| ================================================ | |
| *Release date: 2016-12-03* | |
| Core and Builtins | |
| ----------------- | |
| - Issue #28847: dumbdbm no longer writes the index file in when it is not | |
| changed and supports reading read-only files. | |

| will help to identify the problem especially when the unicode_literals | |
| future import is used. | |
| - Issue #26906: Resolving special methods of uninitialized type now causes | |
| implicit initialization of the type instead of a fail. | |

| potentially have caused off-by-one-ulp results on platforms with | |
| unreliable ldexp implementations. | |

| unicode paths with embedded null character on Windows instead of silently | |
| truncating them. | |

| - Issue #27932: Prevent memory leak in win32_ver(). | |
| - Issue #27888: Prevent Windows installer from displaying console windows and | |

| system Python site-packages directory, to sys.path for macOS framework builds. | |
| The coupling between the two Python instances often caused confusion and, as | |
| of macOS 10.12, changes to the site-packages layout can cause pip component | |
| installations to fail. This change reverts the effects introduced in 2.7.0 | |
| by Issue #4865. If you are using a package with both the Apple system Python | |
| 2.7 and a user-installed Python 2.7, you will need to ensure that copies of | |
| the package are installed with both Python instances. | |

| or __getstate__), can no longer be pickled. Including memoryview. | |
| - Issue #20440: Massive replacing unsafe attribute setting code with special | |
| macro Py_SETREF. | |

| __slots__ defined. | |
| - Issue #19543: Added Py3k warning for decoding unicode. | |
| - Issue #24097: Fixed crash in object.__reduce__() if slot name is freed inside | |
| __getattr__. | |
| - Issue #24731: Fixed crash on converting objects with special methods | |
| __str__, __trunc__, and __float__ returning instances of subclasses of | |

| ================================================ | |
| *Release date: 2015-11-21* | |
| Core and Builtins | |
| ----------------- | |
| - Issue #25678: Avoid buffer overreads when int(), long(), float(), and | |
| compile() are passed buffer objects. These objects are not necessarily | |
| terminated by a null byte, but the functions assumed they were. | |
| - Issue #25388: Fixed tokenizer hang when processing undecodable source code | |
| with a null byte. | |
| - Issue #22995: Default implementation of __reduce__ and __reduce_ex__ now | |
| rejects builtin types with not defined __new__. | |

| not in range(0, 256). | |
| - Issue #24806: Prevent builtin types that are not allowed to be subclassed from | |
| being subclassed through multiple inheritance. | |
| - Issue #24848: Fixed a number of bugs in UTF-7 decoding of misformed data. | |
| - Issue #25003: os.urandom() doesn't use getentropy() on Solaris because | |
| getentropy() is blocking, whereas os.urandom() should not block. getentropy() | |
| is supported since Solaris 11.3. | |
| - Issue #21167: NAN operations are now handled correctly when python is | |
| compiled with ICC even if -fp-model strict is not specified. | |
| - Issue #24467: Fixed possible buffer over-read in bytearray. The bytearray | |
| object now always allocates place for trailing null byte and it's buffer now | |
| is always null-terminated. | |
| - Issue #19543: encode() and decode() methods and constructors of str, | |
| unicode and bytearray classes now emit deprecation warning for known | |
| non-text encodings when Python is ran with the -3 option. | |
| - Issue #24115: Update uses of PyObject_IsTrue(), PyObject_Not(), | |
| PyObject_IsInstance(), PyObject_RichCompareBool() and _PyDict_Contains() | |
| to check for and handle errors correctly. | |
| - Issue #4753: On compilers where it is supported, use "computed gotos" for | |
| bytecode dispatch in the interpreter. This improves interpretation | |
| performance. | |
| - Issue #22939: Fixed integer overflow in iterator object. Original patch by | |
| Clement Rouault. | |
| - Issue #24102: Fixed exception type checking in standard error handlers. | |
| Library | |
| ------- | |
| - Issue #10128: backport issue #10845's mitigation of incompatibilities between | |
| the multiprocessing module and directory and zipfile execution. | |

| whitespace is a substring of smallest leading whitespace. | |
| Based on patch by Robert Li. | |
| - Issue #21709: Fix the logging module to not depend upon __file__ being set | |
| properly to get the filename of its caller from the stack. This allows it | |
| to work if run in a frozen or embedded environment where the module's | |
| .__file__ attribute does not match its code object's .co_filename. | |
| - Issue #25319: When threading.Event is reinitialized, the underlying condition | |
| should use a regular lock rather than a recursive lock. | |
| - Issue #25232: Fix CGIRequestHandler to split the query from the URL at the | |
| first question mark (?) rather than the last. Patch from Xiang Zhang. | |

| - Issue #25135: Make deque_clear() safer by emptying the deque before clearing. | |
| This helps avoid possible reentrancy issues. | |
| - Issue #24684: socket.socket.getaddrinfo() now calls | |
| PyUnicode_AsEncodedString() instead of calling the encode() method of the | |
| host, to handle correctly custom unicode string with an encode() method | |
| which doesn't return a byte string. The encoder of the IDNA codec is now | |
| called directly instead of calling the encode() method of the string. | |
| - Issue #24982: shutil.make_archive() with the "zip" format now adds entries | |
| for directories (including empty directories) in ZIP file. | |
| - Issue #17849: Raise a sensible exception if an invalid response is | |
| received for a HTTP tunnel request, as seen with some servers that | |
| do not support tunnelling. Initial patch from Cory Benfield. | |

| functions of the audioop module. Fixed SystemError when the state is not a | |
| tuple. Fixed possible memory leak. | |
| - Issue #24481: Fix possible memory corruption with large profiler info strings | |
| in hotshot. | |
| - Issue #24489: ensure a previously set C errno doesn't disturb cmath.polar(). | |
| - Issue #19543: io.TextIOWrapper (and hence io.open()) now uses the internal | |
| codec marking system added to emit deprecation warning for known non-text | |
| encodings at stream construction time when Python is ran with the -3 option. | |
| - Issue #24264: Fixed buffer overflow in the imageop module. | |
| - Issue #5633: Fixed timeit when the statement is a string and the setup is not. | |

| - Issue #22095: Fixed HTTPConnection.set_tunnel with default port. The port | |
| value in the host header was set to "None". Patch by Demian Brecht. | |
| - Issue #24257: Fixed segmentation fault in sqlite3.Row constructor with faked | |
| cursor type. | |

| when a directory with the chosen name already exists on Windows as well as | |
| on Unix. tempfile.mkstemp() now fails early if parent directory is not | |
| valid (not exists or is a file) on Windows. | |

| IDLE | |
| ---- | |
| - Issue #15348: Stop the debugger engine (normally in a user process) | |
| before closing the debugger window (running in the IDLE process). | |
| This prevents the RuntimeErrors that were being caught and ignored. | |
| - Issue #24455: Prevent IDLE from hanging when a) closing the shell while the | |
| debugger is active (15347); b) closing the debugger with the [X] button | |
| (15348); and c) activating the debugger when already active (24455). | |
| The patch by Mark Roseman does this by making two changes. | |
| 1. Suspend and resume the gui.interaction method with the tcl vwait | |
| mechanism intended for this purpose (instead of root.mainloop & .quit). | |
| 2. In gui.run, allow any existing interaction to terminate first. | |
| - Change 'The program' to 'Your program' in an IDLE 'kill program?' message | |
| to make it clearer that the program referred to is the currently running | |
| user program, not IDLE itself. | |

| Patch by Mark Roseman. | |
| - Issue #25313: Change the handling of new built-in text color themes to better | |

| Consistently use the revised idleConf.CurrentTheme everywhere in idlelib. | |
| - Issue #24782: Extension configuration is now a tab in the IDLE Preferences | |
| dialog rather than a separate dialog. The former tabs are now a sorted | |
| list. Patch by Mark Roseman. | |
| - Issue #22726: Re-activate the config dialog help button with some content | |
| about the other buttons and the new IDLE Dark theme. | |
| - Issue #24820: IDLE now has an 'IDLE Dark' built-in text color theme. | |
| It is more or less IDLE Classic inverted, with a cobalt blue background. | |
| Strings, comments, keywords, ... are still green, red, orange, ... . | |
| To use it with IDLEs released before November 2015, hit the | |
| 'Save as New Custom Theme' button and enter a new name, | |
| such as 'Custom Dark'. The custom theme will work with any IDLE | |
| release, and can be modified. | |
| - Issue #25224: README.txt is now an idlelib index for IDLE developers and | |
| curious users. The previous user content is now in the IDLE doc chapter. | |
| 'IDLE' now means 'Integrated Development and Learning Environment'. | |
| - Issue #24820: Users can now set breakpoint colors in | |
| Settings -> Custom Highlighting. Original patch by Mark Roseman. | |
| - Issue #24972: Inactive selection background now matches active selection | |
| background, as configured by users, on all systems. Found items are now | |
| always highlighted on Windows. Initial patch by Mark Roseman. | |

| affected by a tk regression. Initial patch by Mark Roseman. | |
| - Issue #24988: Idle ScrolledList context menus (used in debugger) | |
| now work on Mac Aqua. Patch by Mark Roseman. | |

| Patch by Mark Roseman. | |
| - Issue #25173: Associate tkinter messageboxes with a specific widget. | |
| For Mac OSX, make them a 'sheet'. Patch by Mark Roseman. | |
| - Issue #25198: Enhance the initial html viewer now used for Idle Help. | |
| * Properly indent fixed-pitch text (patch by Mark Roseman). | |
| * Give code snippet a very Sphinx-like light blueish-gray background. | |
| * Re-use initial width and height set by users for shell and editor. | |
| * When the Table of Contents (TOC) menu is used, put the section header | |
| at the top of the screen. | |
| - Issue #25225: Condense and rewrite Idle doc section on text colors. | |
| - Issue #21995: Explain some differences between IDLE and console Python. | |
| - Issue #22820: Explain need for *print* when running file from Idle editor. | |
| - Issue #25224: Doc: augment Idle feature list and no-subprocess section. | |
| - Issue #25219: Update doc for Idle command line options. | |
| Some were missing and notes were not correct. | |

| - Issue #25199: Idle: add synchronization comments for future maintainers. | |
| - Issue #16893: Replace help.txt with help.html for Idle doc display. | |
| The new idlelib/help.html is rstripped Doc/build/html/library/idle.html. | |
| It looks better than help.txt and will better document Idle as released. | |
| The tkinter html viewer that works for this file was written by Mark Roseman. | |
| The now unused EditorWindow.HelpDialog class and helt.txt file are deprecated. | |
| - Issue #24199: Deprecate unused idlelib.idlever with possible removal in 3.6. | |
| - Issue #24790: Remove extraneous code (which also create 2 & 3 conflicts). | |
| - Issue #23672: Allow Idle to edit and run files with astral chars in name. | |
| Patch by Mohd Sanad Zaki Rizvi. | |
| - Issue #24745: Idle editor default font. Switch from Courier to | |
| platform-sensitive TkFixedFont. This should not affect current customized | |
| font selections. If there is a problem, edit $HOME/.idlerc/config-main.cfg | |
| and remove 'fontxxx' entries from [Editor Window]. Patch by Mark Roseman. | |
| - Issue #21192: Idle editor. When a file is run, put its name in the restart bar. | |
| Do not print false prompts. Original patch by Adnan Umer. | |
| - Issue #13884: Idle menus. Remove tearoff lines. Patch by Roger Serwy. | |

| a test run is no longer marked as a failure if all tests succeed when | |
| re-run. | |
| - PCbuild\rt.bat now accepts an unlimited number of arguments to pass along | |
| to regrtest.py. Previously there was a limit of 9. | |
| Build | |
| ----- | |
| - Issue #24915: When doing a PGO build, the test suite is now used instead of | |

| - Issue #24986: It is now possible to build Python on Windows without errors | |
| when external libraries are not available. | |
| - Issue #24508: Backported the MSBuild project files from Python 3.5. The | |
| backported files replace the old project files in PCbuild; the old files moved | |
| to PC/VS9.0 and remain supported. | |
| - Issue #24603: Update Windows builds and OS X 10.5 installer to use OpenSSL | |
| 1.0.2d. | |

| and Victor Stinner. | |
| - Issue #14432: Generator now clears the borrowed reference to the thread | |
| state. Fix a crash when a generator is created in a C thread that is | |
| destroyed while the generator is still used. The issue was that a generator | |
| contains a frame, and the frame kept a reference to the Python state of the | |
| destroyed C thread. The crash occurs when a trace function is setup. | |

| prints out the whole command line (instead of just the command name) if the | |
| environment variable DISTUTILS_DEBUG is set. | |
| - Issue #4931: distutils should not produce unhelpful "error: None" messages | |
| anymore. distutils.util.grok_environment_error is kept but doc-deprecated. | |
| - Improve the random module's default seeding to use 256 bits of entropy | |
| from os.urandom(). This was already done for Python 3, mildly improving | |

| Extension Modules | |
| ----------------- | |
| - Issue #17477: Update the bsddb module to pybsddb 5.3.0, supporting | |
| db-5.x, and dropping support for db-4.1 and db-4.2. | |
| - Issue #17192: Update the ctypes module's libffi to v3.0.13. This | |
| specifically addresses a stack misalignment issue on x86 and issues on | |
| some more recent platforms. | |
| - Issue #12268: The io module file object write methods no longer abort early | |
| when a write system calls is interrupted (EINTR). | |
| - Fix the leak of a dict in the time module when used in an embedded | |
| interpreter that is repeatedly initialized and shutdown and reinitialized. | |
| - Issue #12268: File readline, readlines and read or readall methods | |
| no longer lose data when an underlying read system call is interrupted | |
| within an io module object. IOError is no longer raised due to a read | |
| system call returning EINTR from within these methods. | |
| - Issue #16012: Fix a regression in pyexpat. The parser's UseForeignDTD() | |
| method doesn't require an argument again. | |
| - Issue #13590: OS X Xcode 4 - improve support for universal extension modules | |
| In particular, fix extension module build failures when trying to use | |
| 32-bit-only installer Pythons on systems with Xcode 4 (currently | |
| OS X 10.8, 10.7, and optionally 10.6). | |
| * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4) | |
| * Since Xcode 4 removes ppc support, extension module builds now | |
| check for ppc compiler support and by default remove ppc and | |
| ppc64 archs when they are not available. | |
| * Extension module builds now revert to using system installed | |
| headers and libs (/usr and /System/Library) if the SDK used | |
| to build the interpreter is not installed or has moved. | |
| * Try to avoid building extension modules with deprecated | |
| and problematic Apple llvm-gcc compiler. If original compiler | |
| is not available, use clang instead by default. | |

| What's New in Python 2.7.3 release candidate 1? | |
| =============================================== | |
| *Release date: 2012-02-23* | |
| Core and Builtins | |
| ----------------- | |
| - Issue #13020: Fix a reference leak when allocating a structsequence object | |
| fails. Patch by Suman Saha. | |
| - Issue #13703: oCERT-2011-003: add -R command-line option and PYTHONHASHSEED | |
| environment variable, to provide an opt-in way to protect against denial of | |
| service attacks due to hash collisions within the dict and set types. Patch | |
| by David Malcolm, based on work by Victor Stinner. | |
| - Issue #11235: Fix OverflowError when trying to import a source file whose | |
| modification time doesn't fit in a 32-bit timestamp. | |
| - Issue #11638: Unicode strings in 'name' and 'version' no longer cause | |
| UnicodeDecodeErrors. | |
| - Fix the fix for issue #12149: it was incorrect, although it had the side | |
| effect of appearing to resolve the issue. Thanks to Mark Shannon for | |
| noticing. | |
| - Issue #13546: Fixed an overflow issue that could crash the intepreter when | |
| calling sys.setrecursionlimit((1<<31)-1). | |
| - Issue #13333: The UTF-7 decoder now accepts lone surrogates (the encoder | |
| already accepts them). | |
| - Issue #10519: Avoid unnecessary recursive function calls in | |
| setobject.c. | |
| - Issue #13268: Fix the assert statement when a tuple is passed as the message. | |
| - Issue #13018: Fix reference leaks in error paths in dictobject.c. | |
| Patch by Suman Saha. | |
| - Issue #12604: VTRACE macro expanded to no-op in _sre.c to avoid compiler | |
| warnings. Patch by Josh Triplett and Petri Lehtinen. | |
| - Issue #7833: Extension modules built using distutils on Windows will no | |
| longer include a "manifest" to prevent them failing at import time in some | |
| embedded situations. | |

| PySequence_DelItem. | |
| - Issue #13156: Revert the patch for issue #10517 (reset TLS upon fork()), | |
| which was only relevant for the native pthread TLS implementation. | |
| - Issue #7732: Fix a crash on importing a module if a directory has the same | |
| name than a Python module (e.g. "__init__.py"): don't close the file twice. | |
| - Issue #12973: Fix overflow checks that invoked undefined behaviour in | |
| int.__pow__. These overflow checks were causing int.__pow__ to produce | |
| incorrect results with recent versions of Clang, as a result of the | |
| compiler optimizing the check away. Also fix similar overflow checks | |
| in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These | |
| bugs caused test failures with recent versions of Clang. | |
| - Issue #12266: Fix str.capitalize() to correctly uppercase/lowercase | |
| titlecased and cased non-letter characters. | |
| - Issues #12610 and #12609: Verify that user generated AST has correct string | |

| and its type get caught in a reference cycle, and the instance's | |
| deallocator calls one of the methods on the type (e.g. when subclassing | |
| IOBase). Diagnosis and patch by Davide Rizzo. | |
| - Issue #12501: Remove Py3k warning for callable. callable() is supported | |
| again in Python 3.2. | |
| - Issue #9611, #9015: FileIO.read(), FileIO.readinto(), FileIO.write() and | |
| os.write() clamp the length to INT_MAX on Windows. | |
| - Issue #1195: my_fgets() now always clears errors before calling fgets(). Fix | |
| the following case: sys.stdin.read() stopped with CTRL+d (end of file), | |
| raw_input() interrupted by CTRL+c. | |
| - Issue #10860: httplib now correctly handles an empty port after port | |
| delimiter in URLs. | |

| - Issue #13993: HTMLParser is now able to handle broken end tags. | |
| - Issue #13960: HTMLParser is now able to handle broken comments. | |
| - Issue #9750: Fix sqlite3.Connection.iterdump on tables and fields | |
| with a name that is a keyword or contains quotes. Patch by Marko | |
| Kohtala. | |
| - Issue #13994: Earlier partial revert of Distutils enhancements in 2.7 | |
| has left two versions of customize_compiler, the original in | |
| distutils.sysconfig and another copy in distutils.ccompiler, with some | |
| parts of distutils calling one and others using the other. | |
| Complete the revert back to only having one in distutils.sysconfig as | |
| is the case in 3.x. | |
| - Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building | |
| Distutils-based packages with C extension modules may fail because | |
| Apple has removed gcc-4.2, the version used to build python.org | |
| 64-bit/32-bit Pythons. If the user does not explicitly override | |
| the default C compiler by setting the CC environment variable, | |
| Distutils will now attempt to compile extension modules with clang | |
| if gcc-4.2 is required but not found. Also as a convenience, if | |
| the user does explicitly set CC, substitute its value as the default | |
| compiler in the Distutils LDSHARED configuration variable for OS X. | |
| (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u | |
| SDK, neither of which are available in Xcode 4. This change does not | |
| attempt to override settings to support their use with Xcode 4.) | |

| does, instead of converting it to a raw buffer. This also fixes handling of | |
| unicode input in the shlex module (#6988, #1170). | |

| - Issue #12352: Fix a deadlock in multiprocessing.Heap when a block is freed by | |
| the garbage collector while the Heap lock is held. | |
| - Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to | |
| check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the | |
| interpreter process. This could cause failures in non-Distutils subprocesses | |
| and was unreliable since tests or user programs could modify the interpreter | |
| environment after Distutils set it. Instead, have Distutils set the | |
| deployment target only in the environment of each build subprocess. It is | |
| still possible to globally override the default by setting | |
| MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be | |
| greater or equal to the default value, the value with which the interpreter | |
| was built. | |
| - Issue #11802: The cache in filecmp now has a maximum size of 100 so that | |
| it won't grow without bound. | |

| connection if its getresponse() method fails with a socket error. Patch | |
| written by Ezio Melotti. | |
| - Issue #9284: Allow inspect.findsource() to find the source of doctest | |
| functions. | |

| instead of os.stat. | |
| - Issue #12080: Fix a performance issue in Decimal._power_exact that caused | |
| some corner-case Decimal.__pow__ calls to take an unreasonably long time. | |
| - Named tuples now work correctly with vars(). | |
| - sys.setcheckinterval() now updates the current ticker count as well as | |
| updating the check interval, so if the user decreases the check interval, | |
| the ticker doesn't have to wind down to zero from the old starting point | |
| before the new interval takes effect. And if the user increases the | |
| interval, it makes sure the new limit takes effect right away rather have an | |
| early task switch before recognizing the new interval. | |
| - Issue #12085: Fix an attribute error in subprocess.Popen destructor if the | |
| constructor has failed, e.g. because of an undeclared keyword argument. Patch | |
| written by Oleg Oshmyan. | |

| files, display a message popup and continue rather than crash. | |
| (original patch by Roger Serwy) | |
| - Issue #8793: Prevent IDLE crash when given strings with invalid hex escape | |
| sequences. | |
| - Issue #13296: Fix IDLE to clear compile __future__ flags on shell restart. | |
| (Patch by Roger Serwy) | |
| - Issue #14409: IDLE now properly executes commands in the Shell window | |
| when it cannot read the normal config files on startup and | |
| has to use the built-in default key bindings. | |
| There was previously a bug in one of the defaults. | |
| - Issue #3573: IDLE hangs when passing invalid command line args | |

| Core and Builtins | |
| ----------------- | |
| - Issue #9670: Increase the default stack size for secondary threads on | |
| Mac OS X and FreeBSD to reduce the chances of a crash instead of a | |
| "maximum recursion depth" RuntimeError exception. | |
| (patch by Ronald Oussoren) | |
| - Correct lookup of __dir__ on objects. This allows old-style classes to have | |
| __dir__. It also causes errors besides AttributeError found on lookup to be | |
| propagated. | |
| - Issue #1195: Fix input() if it is interrupted by CTRL+d and then CTRL+c, | |
| clear the end-of-file indicator after CTRL+d. | |
| - Issue #8651: PyArg_Parse*() functions raise an OverflowError if the file | |
| doesn't have PY_SSIZE_T_CLEAN define and the size doesn't fit in an int | |
| (length bigger than 2^31-1 bytes). | |
| - Issue #8651: Fix "z#" format of PyArg_Parse*() function: the size was not | |
| written if PY_SSIZE_T_CLEAN is defined. | |
| - Issue #9756: When calling a method descriptor or a slot wrapper descriptor, | |
| the check of the object type doesn't read the __class__ attribute anymore. | |
| Fix a crash if a class override its __class__ attribute (e.g. a proxy of the | |
| str type). Patch written by Andreas Stührk. | |
| - Issue #10517: After fork(), reinitialize the TLS used by the PyGILState_* | |
| APIs, to avoid a crash with the pthread implementation in RHEL 5. Patch | |

| (EINTR), for example if the program is stopped with CTRL+z on Mac OS X. Patch | |
| written by Charles-Francois Natali. | |
| - Issue #11144: Ensure that int(a_float) returns an int whenever possible. | |
| Previously, there were some corner cases where a long was returned even | |
| though the result was within the range of an int. | |
| - Issue #11450: Don't truncate hg version info in Py_GetBuildInfo() when | |
| there are many tags (e.g. when using mq). Patch by Nadeem Vawda. | |
| - Issue #10451: memoryview objects could allow mutating a readable buffer. | |
| Initial patch by Ross Lagerwall. | |
| - Issue #10892: Don't segfault when trying to delete __abstractmethods__ from a | |
| class. | |

| - Issue #8278: On Windows and with a NTFS filesystem, os.stat() and os.utime() | |
| can now handle dates after 2038. | |
| - Issue #4236: Py_InitModule4 now checks the import machinery directly | |
| rather than the Py_IsInitialized flag, avoiding a Fatal Python | |
| error in certain circumstances when an import is done in __del__. | |
| - Issue #11828: startswith and endswith don't accept None as slice index. | |
| Patch by Torsten Becker. | |
| - Issue #10674: Remove unused 'dictmaker' rule from grammar. | |
| - Issue #10596: Fix float.__mod__ to have the same behaviour as | |
| float.__divmod__ with respect to signed zeros. -4.0 % 4.0 should be | |
| 0.0, not -0.0. | |
| - Issue #11386: bytearray.pop() now throws IndexError when the bytearray is | |
| empty, instead of OverflowError. | |

| were given to it. Patch by Brian Brazil. | |
| - Issue #10253: FileIO leaks a file descriptor when trying to open a file | |
| for append that isn't seekable. Patch by Brian Brazil. | |
| - Issue #6105: json.dumps now respects OrderedDict's iteration order. | |
| - Issue #9295: Fix a crash under Windows when calling close() on a file | |
| object with custom buffering from two threads at once. | |
| - Issue #5027: The standard ``xml`` namespace is now understood by | |
| xml.sax.saxutils.XMLGenerator as being bound to | |
| http://www.w3.org/XML/1998/namespace. Patch by Troy J. Farrell. | |
| - Issue #10163: Skip unreadable registry keys during mimetypes | |
| initialization. | |
| - Issue #5117: Fixed root directory related issue on posixpath.relpath() and | |
| ntpath.relpath(). | |

| debugging in doctests. | |
| - Issue #6612: Fix site and sysconfig to catch os.getcwd() error, eg. if the | |

| - Issue #9437: Fix building C extensions with non-default LDFLAGS. | |
| - Issue #9759: GzipFile now raises ValueError when an operation is attempted | |
| after the file is closed. Patch by Jeffrey Finkelstein. | |
| - Issue #9042: Fix interaction of custom translation classes and caching in | |
| gettext. | |
| - Issue #9065: tarfile no longer uses "root" as the default for the uname and | |

| characters that appear inside quoted strings in email addresses. | |
| - Issue #10004: quoprimime no longer generates a traceback when confronted | |
| with invalid characters after '=' in a Q-encoded word. | |
| - Issue #9950: Fix socket.sendall() crash or misbehaviour when a signal is | |
| received. Now sendall() properly calls signal handlers if necessary, | |
| and retries sending if these returned successfully, including on sockets | |
| with a timeout. | |
| - Issue #9947: logging: Fixed locking bug in stopListening. | |
| - Issue #9945: logging: Fixed locking bugs in addHandler/removeHandler. | |

| handles non-blocking readinto() returning None correctly. | |
| - Issue #9729: Fix the signature of SSLSocket.recvfrom() and | |
| SSLSocket.sendto() to match the corresponding socket methods. Also, | |
| fix various SSLSocket methods to raise socket.error rather than an | |
| unhelpful TypeError when called on an unconnected socket. Original patch | |
| by Andrew Bennetts. | |
| - Issue #9826: OrderedDict.__repr__ can now handle self-referential | |
| values: d['x'] = d. | |
| - Issue #767645: Set os.path.supports_unicode_filenames to True on Mac OS X. | |
| - Issue #9837: The read() method of ZipExtFile objects (as returned by | |
| ZipFile.open()) could return more bytes than requested. | |
| - Issue #9825: removed __del__ from the definition of collections.OrderedDict. | |
| This prevents user-created self-referencing ordered dictionaries from | |
| becoming permanently uncollectable GC garbage. The downside is that | |
| removing __del__ means that the internal doubly-linked list has to wait for | |
| GC collection rather than freeing memory immediately when the refcnt drops | |
| to zero. | |
| - Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently | |
| different internal state for small values of n. Fixed by salting the | |
| value. | |
| - Issue #9792: In case of connection failure, socket.create_connection() | |
| would swallow the exception and raise a new one, making it impossible | |
| to fetch the original errno, or to filter timeout errors. Now the | |
| original error is re-raised. | |
| - Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True, | |
| and the passed buffer was exactly 1024 bytes long, the buffer wouldn't | |
| be updated back after the system call. Original patch by Brian Brazil. | |
| - Issue #1100562: Fix deep-copying of objects derived from the list and | |
| dict types. Patch by Michele Orrù and Björn Lindqvist. | |
| - Issue #7005: Fixed output of None values for RawConfigParser.write and | |
| ConfigParser.write. | |
| - Issue #808164: Fixed socket.close to avoid references to globals, to | |
| avoid issues when socket.close is called from a __del__ method. | |
| - Issue #2986: difflib.SequenceMatcher gets a new parameter, autojunk, which | |
| can be set to False to turn off the previously undocumented 'popularity' | |
| heuristic. Patch by Terry Reedy and Eli Bendersky | |
| - Issue #8797: urllib2 does a retry for Basic Authentication failure instead of | |
| falling into recursion. | |
| - Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four | |
| character years even if the message contains RFC822 two character years. | |
| - Issue #8750: Fixed MutableSet's methods to correctly handle | |
| reflexive operations, namely x -= x and x ^= x. | |
| - Issue #9129: smtpd.py is vulnerable to DoS attacks deriving from missing | |
| error handling when accepting a new connection. | |
| - Issue #658749: asyncore's connect() method now correctly interprets winsock | |
| errors. | |
| - Issue #9501: Fixed logging regressions in cleanup code. | |
| - Issue #9214: Set operations on KeysView or ItemsView in the collections | |
| module now correctly return a set. (Patch by Eli Bendersky.) | |
| - Issue #9617: Signals received during a low-level write operation aren't | |
| ignored by the buffered IO layer anymore. | |
| - Issue #2521: Use weakrefs on for caching in the abc module, so that classes | |
| are not held onto after they are deleted elsewhere. | |
| - Issue #9626: the view methods for collections.OrderedDict() were returning | |
| the unordered versions inherited from dict. Those methods are now | |
| overridden to provide ordered views. | |
| - Issue #8688: MANIFEST files created by distutils now include a magic | |
| comment indicating they are generated. Manually maintained MANIFESTs | |
| without this marker will not be overwritten or removed. | |
| - Issue #7467: when reading a file from a ZIP archive, its CRC is checked | |
| and a BadZipfile error is raised if it doesn't match (as used to be the | |
| case in Python 2.5 and earlier). | |
| - Issue #9550: a BufferedReader could issue an additional read when the | |
| original read request had been satisfied, which could block indefinitely | |
| when the underlying raw IO channel was e.g. a socket. Report and original | |
| patch by Jason V. Miller. | |
| - Issue #9551: Don't raise TypeError when setting the value to None for | |
| SafeConfigParser instances constructed with allow_no_value == True. | |
| - Issue #6915: Under Windows, os.listdir() didn't release the Global | |
| Interpreter Lock around all system calls. Original patch by Ryan Kelly. | |
| - Issue #3757: thread-local objects now support cyclic garbage collection. | |
| Thread-local objects involved in reference cycles will be deallocated | |
| timely by the cyclic GC, even if the underlying thread is still running. | |

| current node. | |
| - Issue #6869: Fix a refcount problem in the _ctypes extension. | |
| - Issue #5504: ctypes should now work with systems where mmap can't be | |
| PROT_WRITE and PROT_EXEC. | |
| - Issue #8280: urllib2's Request method will remove fragements in the url. | |
| This is how it is supposed to work, wget and curl do the same. Previous | |
| behavior was wrong. | |
| - Issue #2944: asyncore doesn't handle connection refused correctly. | |
| - Issue #3196: email header decoding is now forgiving if an RFC2047 | |
| encoded word encoded in base64 is lacking padding. | |
| - Issue #9444: Argparse now uses the first element of prefix_chars as | |
| the option character for the added 'h/help' option if prefix_chars | |
| does not contain a '-', instead of raising an error. | |
| - Issue #9354: Provide getsockopt() in asyncore's file_wrapper. | |

| the command line. | |

| XML-RPC request. | |
| - Issue #5542: Remove special logic that closes HTTPConnection socket on EPIPE. | |
| - Issue #4629: getopt raises an error if an argument ends with = whereas getopt | |

| What's New in Python 2.7 Release Candidate 1? | |
| ============================================= | |
| *Release date: 2010-06-05* | |
| Core and Builtins | |
| ----------------- | |
| - Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the | |
| start byte and the continuation byte(s) are now considered invalid, instead | |
| of the number of bytes specified by the start byte. | |
| E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and | |
| replaces with U+FFFD only the start byte ('\xf1') and the continuation byte | |
| ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence. | |
| Previous versions returned a single u'\ufffd'. | |
| - Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of | |
| __hash__ in 3.x" warning. Also fix "XXX undetected error" that | |
| arises from the "Overriding __eq__ blocks inheritance ..." warning | |
| when turned into an exception: in this case the exception simply | |
| gets ignored. | |
| - Issue #8748: Fix two issues with comparisons between complex and integer | |
| objects. (1) The comparison could incorrectly return True in some cases | |
| (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality. | |
| (2) The comparison raised an OverflowError for large integers, leading | |
| to unpredictable exceptions when combining integers and complex objects | |
| in sets or dicts. | |
| - Issue #5211: Implicit coercion for the complex type is now completely | |
| removed. (Coercion for arithmetic operations was already removed in 2.7 | |
| alpha 4, but coercion for rich comparisons was accidentally left in.) | |
| - Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding | |
| and error handler, instead of writing to the C stderr file in utf-8 | |
| - Issue #7902: When using explicit relative import syntax, don't try implicit | |
| relative import semantics. | |
| - Issue #7079: Fix a possible crash when closing a file object while using it | |
| from another thread. Patch by Daniel Stutzbach. | |
| - Issue #8868: Fix that ensures that python scripts have access to the | |
| Window Server again in a framework build on MacOSX 10.5 or earlier. | |
| C-API | |
| ----- | |
| - Issue #5753: A new C API function, :cfunc:`PySys_SetArgvEx`, allows embedders | |
| of the interpreter to set sys.argv without also modifying sys.path. This | |
| helps fix `CVE-2008-5983 | |
| <http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-5983>`_. | |
| Library | |
| ------- | |
| - Issue #8302: SkipTest in unittest.TestCase.setUpClass or setUpModule is now | |
| reported as a skip rather than an error. | |
| - Issue #8351: Excessively large diffs due to | |
| unittest.TestCase.assertSequenceEqual are no longer included in failure | |
| reports. | |
| - Issue #8899: time.struct_time now has class and attribute docstrings. | |
| - Issue #4487: email now accepts as charset aliases all codec aliases | |
| accepted by the codecs module. | |
| - Issue #6470: Drop UNC prefix in FixTk. | |
| - Issue #5610: feedparser no longer eats extra characters at the end of | |
| a body part if the body part ends with a \r\n. | |
| - Issue #8833: tarfile created hard link entries with a size field != 0 by | |
| mistake. | |
| - Issue #1368247: set_charset (and therefore MIMEText) now automatically | |
| encodes a unicode _payload to the output_charset. | |
| - Issue #7150: Raise OverflowError if the result of adding or subtracting | |
| timedelta from date or datetime falls outside of the MINYEAR:MAXYEAR range. | |
| - Issue #6662: Fix parsing of malformatted charref (&#bad;), patch written by | |
| Fredrik Håård | |
| - Issue #8016: Add the CP858 codec. | |
| - Issue #3924: Ignore cookies with invalid "version" field in cookielib. | |
| - Issue #6268: Fix seek() method of codecs.open(), don't read or write the BOM | |
| twice after seek(0). Fix also reset() method of codecs, UTF-16, UTF-32 and | |
| StreamWriter classes. | |
| - Issue #5640: Fix Shift-JIS incremental encoder for error handlers different | |
| than 'strict'. | |
| - Issue #8782: Add a trailing newline in linecache.updatecache to the last line | |
| of files without one. | |
| - Issue #8729: Return NotImplemented from ``collections.Mapping.__eq__()`` when | |
| comparing to a non-mapping. | |
| - Issue #8759: Fix user paths in sysconfig for posix and os2 schemes. | |
| - Issue #1285086: Speed up ``urllib.quote()`` and urllib.unquote for simple | |
| cases. | |
| - Issue #8688: Distutils now recalculates MANIFEST every time. | |
| - Issue #5099: The ``__del__()`` method of ``subprocess.Popen`` (and the methods | |
| it calls) referenced global objects, causing errors to pop up during | |
| interpreter shutdown. | |
| Extension Modules | |
| ----------------- | |
| - Issue #7384: If the system readline library is linked against ncurses, | |
| the curses module must be linked against ncurses as well. Otherwise it | |
| is not safe to load both the readline and curses modules in an application. | |
| - Issue #2810: Fix cases where the Windows registry API returns | |
| ERROR_MORE_DATA, requiring a re-try in order to get the complete result. | |
| - Issue #8674: Fixed a number of incorrect or undefined-behaviour-inducing | |
| overflow checks in the ``audioop`` module. | |
| Tests | |
| ----- | |
| - Issue #8889: test_support.transient_internet rewritten so that the new | |
| checks also work on FreeBSD, which lacks EAI_NODATA. | |
| - Issue #8835: test_support.transient_internet() catches gaierror(EAI_NONAME) | |
| and gaierror(EAI_NODATA) | |
| - Issue #7449: Skip test_socketserver if threading support is disabled | |
| - On darwin, ``test_site`` assumed that a framework build was being used, | |
| leading to a failure where four directories were expected for site-packages | |
| instead of two in a non-framework build. | |
| Build | |
| ----- | |
| - Display installer warning that Windows 2000 won't be supported in future | |
| releases. | |
| - Issues #1759169, #8864: Drop _XOPEN_SOURCE on Solaris, define it for | |
| multiprocessing only. | |
| Tools/Demos | |
| ----------- | |
| - Issue #5464: Implement plural forms in msgfmt.py. | |
| What's New in Python 2.7 beta 2? | |
| ================================ | |
| *Release date: 2010-05-08* | |
| Core and Builtins | |
| ----------------- | |
| - Run Clang 2.7's static analyzer for ``Objects/`` and ``Python/``. | |
| - Issue #1533: Fix inconsistency in range function argument processing: any | |
| non-float non-integer argument is now converted to an integer (if possible) | |
| using its __int__ method. Previously, only small arguments were treated this | |
| way; larger arguments (those whose __int__ was outside the range of a C long) | |
| would produce a TypeError. | |
| - Issue #8202: ``sys.argv[0]`` is now set to '-m' instead of '-c' when searching | |
| for the module file to be executed with the -m command line option. | |
| - Issue #7319: When -Q is used, do not silence DeprecationWarning. | |
| - Issue #7332: Remove the 16KB stack-based buffer in | |
| ``PyMarshal_ReadLastObjectFromFile``, which doesn't bring any noticeable | |
| benefit compared to the dynamic memory allocation fallback. Patch by | |
| Charles-François Natali. | |
| - Issue #8417: Raise an OverflowError when an integer larger than sys.maxsize is | |
| passed to bytearray. | |
| - Issue #7072: ``isspace(0xa0)`` is true on Mac OS X. | |
| - Issue #8404: Fix set operations on dictionary views. | |
| - Issue #8084: PEP 370 now conforms to system conventions for framework builds | |
| on MacOS X. That is, ``python setup.py install --user`` will install into | |
| ``~/Library/Python/2.7`` instead of ``~/.local``. | |
| Library | |
| ------- | |
| - Issue #8681: Make the zlib module's error messages more informative when the | |
| zlib itself doesn't give any detailed explanation. | |
| - Issue #8571: Fix an internal error when compressing or decompressing a chunk | |
| larger than 1GB with the zlib module's compressor and decompressor objects. | |
| - Issue #8573: asyncore ``_strerror()`` function might throw ValueError. | |
| - Issue #8483: asyncore.dispatcher's __getattr__ method produced confusing error | |
| messages when accessing undefined class attributes because of the cheap | |
| inheritance with the underlying socket object. The cheap inheritance has been | |
| deprecated. | |
| - Issue #4265: ``shutil.copyfile()`` was leaking file descriptors when disk | |
| fills. Patch by Tres Seaver. | |
| - Issue #7755: Use an unencumbered audio file for tests. | |
| - Issue #8621: ``uuid.uuid4()`` returned the same sequence of values in the | |
| parent and any children created using ``os.fork`` on Mac OS X 10.6. | |
| - Issue #8313: ``traceback.format_exception_only()`` encodes unicode message to | |
| ASCII with backslashreplace error handler if ``str(value)`` failed. | |
| - Issue #8567: Fix precedence of signals in Decimal module: when a Decimal | |
| operation raises multiple signals and more than one of those signals is | |
| trapped, the specification determines the order in which the signals should be | |
| handled. In many cases this order wasn't being followed, leading to the wrong | |
| Python exception being raised. | |
| - Issue #7865: The close() method of :mod:`io` objects should not swallow | |
| exceptions raised by the implicit flush(). Also ensure that calling close() | |
| several times is supported. Patch by Pascal Chambon. | |
| - Issue #8576: logging updated to remove usage of find_unused_port(). | |
| - Issue #4687: Fix accuracy of garbage collection runtimes displayed with | |
| gc.DEBUG_STATS. | |
| - Issue #8354: The siginterrupt setting is now preserved for all signals, not | |
| just SIGCHLD. | |
| - Issue #7192: ``webbrowser.get("firefox")`` now works on Mac OS X, as does | |
| ``webbrowser.get("safari")``. | |
| - Issue #8577: ``distutils.sysconfig.get_python_inc()`` now makes a difference | |
| between the build dir and the source dir when looking for "python.h" or | |
| "Include". | |
| - Issue #8464: tarfile no longer creates files with execute permissions set when | |
| mode="w|" is used. | |
| - Issue #7834: Fix connect() of Bluetooth L2CAP sockets with recent versions of | |
| the Linux kernel. Patch by Yaniv Aknin. | |
| - Issue #6312: Fix http HEAD request when the transfer encoding is chunked. It | |
| should correctly return an empty response now. | |
| - Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test | |
| suites, the ``IGNORE_EXCEPTION_DETAIL`` directive now also ignores the module | |
| location of the raised exception. Based on initial patch by Lennart Regebro. | |
| - Issue #8086: In :func:`ssl.DER_cert_to_PEM_cert()`, fix missing newline before | |
| the certificate footer. Patch by Kyle VanderBeek. | |
| - Issue #8546: Reject None given as the buffering argument to ``_pyio.open()``. | |
| - Issue #8549: Fix compiling the _ssl extension under AIX. Patch by Sridhar | |
| Ratnakumar. | |
| - Issue #6656: Fix locale.format_string to handle escaped percents and mappings. | |
| - Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown, where | |
| the method could block indefinitely if called just before the event loop | |
| started running. This also fixes the occasional freezes witnessed in | |
| test_httpservers. | |
| - Issue #5103: SSL handshake would ignore the socket timeout and block | |
| indefinitely if the other end didn't respond. | |
| - The do_handshake() method of SSL objects now adjusts the blocking mode of the | |
| SSL structure if necessary (as other methods already do). | |
| - Issue #7507: Quote "!" in pipes.quote(); it is special to some shells. | |
| - Issue #5238: Calling makefile() on an SSL object would prevent the underlying | |
| socket from being closed until all objects get truely destroyed. | |
| - Issue #7943: Fix circular reference created when instantiating an SSL socket. | |
| Initial patch by Péter Szabó. | |
| - Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of the | |
| string "python" as the *ident*. openlog() arguments are all optional and | |
| keywords. | |
| - Issue #8108: Fix the unwrap() method of SSL objects when the socket has a | |
| non-infinite timeout. Also make that method friendlier with applications | |
| wanting to continue using the socket in clear-text mode, by disabling | |
| OpenSSL's internal readahead. Thanks to Darryl Miles for guidance. | |
| - Issue #8484: Load all ciphers and digest algorithms when initializing the _ssl | |
| extension, such that verification of some SSL certificates doesn't fail | |
| because of an "unknown algorithm". | |
| - Issue #8437: Fix test_gdb failures, patch written by Dave Malcolm | |
| - Issue #4814: The timeout parameter is now applied also for connections | |
| resulting from PORT/EPRT commands. | |
| - Issue #8463: Add missing reference to bztar in shutil's documentation. | |
| - Issue #8438: Remove reference to the missing "surrogateescape" encoding error | |
| handler from the new IO library. | |
| - Issue #3817: ftplib.FTP.abort() method now considers 225 a valid response code | |
| as stated in RFC-959 at chapter 5.4. | |
| - Issue #8279: Fix test_gdb failures. | |
| - Issue #8322: Add a *ciphers* argument to SSL sockets, so as to change the | |
| available cipher list. Helps fix test_ssl with OpenSSL 1.0.0. | |
| - Issue #2987: RFC 2732 support for urlparse (IPv6 addresses). Patch by Tony | |
| Locke and Hans Ulrich Niedermann. | |
| - Issue #7585: difflib context and unified diffs now place a tab between | |
| filename and date, conforming to the 'standards' they were originally designed | |
| to follow. This improves compatibility with patch tools. | |
| - Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022 | |
| character sets will now consistently use a Content-Transfer-Encoding of 7bit | |
| rather than sometimes being marked as 8bit. | |
| - Issue #8330: Fix expected output in test_gdb. | |
| - Issue #8374: Update the internal alias table in the :mod:`locale` module to | |
| cover recent locale changes and additions. | |
| Extension Modules | |
| ----------------- | |
| - Issue #8644: Improved accuracy of ``timedelta.total_seconds()``. | |
| - Use Clang 2.7's static analyzer to find places to clean up some code. | |
| - Build the ossaudio extension on GNU/kFreeBSD. | |
| - On Windows, ctypes no longer checks the stack before and after calling a | |
| foreign function. This allows using the unmodified libffi library. | |
| Tests | |
| ----- | |
| - Issue #8672: Add a zlib test ensuring that an incomplete stream can be handled | |
| by a decompressor object without errors (it returns incomplete uncompressed | |
| data). | |
| - Issue #8490: asyncore now has a more solid test suite which actually tests its | |
| API. | |
| - Issue #8576: Remove use of find_unused_port() in test_smtplib and | |
| test_multiprocessing. Patch by Paul Moore. | |
| - Issue #7449: Fix many tests to support Python compiled without thread support. | |
| Patches written by Jerry Seutter. | |
| - Issue #8108: test_ftplib's non-blocking SSL server now has proper handling of | |
| SSL shutdowns. | |
| Build | |
| ----- | |
| - Issue #8625: Turn off optimization in ``--with-pydebug`` builds with gcc. | |
| (Optimization was unintentionally turned on in gcc --with-pydebug builds in | |
| 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's | |
| strange choice of default CFLAGS produced by AC_PROG_CC for gcc.) | |
| - Issue #8509: Fix quoting in help strings and code snippets in configure.in. | |
| - Issue #3646: It is now easily possible to install a Python framework into your | |
| home directory on Mac OS X, see Mac/README for more information. | |
| - Issue #8510: Update to autoconf 2.65. | |
| Misc | |
| ---- | |
| - Update the Vim syntax highlight file. | |
| What's New in Python 2.7 beta 1? | |
| ================================ | |
| *Release date: 2010-04-10* | |
| Core and Builtins | |
| ----------------- | |
| - Issue #7301: Add environment variable $PYTHONWARNINGS. | |
| - Issue #8329: Don't return the same lists from select.select when no fds are | |
| changed. | |
| - Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error' | |
| on 64-bit machines. The shift count for either left or right shift is | |
| permitted to be up to sys.maxsize. | |
| - Ensure that tokenization of identifiers is not affected by locale. | |
| - Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever. | |
| - Raise a TypeError when trying to delete a T_STRING_INPLACE struct member. | |
| - Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called | |
| with a non-empty format string. This is an effort to future-proof user | |
| code. If a derived class does not currently implement __format__ but later | |
| adds its own __format__, it would most likely break user code that had | |
| supplied a format string. This will be changed to a DeprecationWarning in | |
| Python 3.3 and it will be an error in Python 3.4. | |
| - Issue #8268: Old-style classes (not just instances) now support weak | |
| references. | |
| - Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, in case it | |
| is set. | |
| - Issue #1583863: A unicode subclass can now override the __unicode__ method | |
| - Issue #6474: Make error message from passing an inadequate number of keyword | |
| arguments to a function correct. | |
| - Issue #8164: Don't allow lambda functions to have a docstring. | |
| - Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt | |
| (SIGINT). If an error occurs while importing the site module, the error is | |
| printed and Python exits. Initialize the GIL before importing the site | |
| module. | |
| - Code objects now support weak references. | |
| Library | |
| ------- | |
| - Issue #5277: Fix quote counting when parsing RFC 2231 encoded parameters. | |
| - Issue #8321: Give access to OpenSSL version numbers from the `ssl` module, | |
| using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and | |
| `ssl.OPENSSL_VERSION_NUMBER`. | |
| - Issue #8310: Allow dis to examine new style classes. | |
| - Issue #8257: The Decimal construct now accepts a float instance directly, | |
| converting that float to a Decimal of equal value: | |
| >>> Decimal(1.1) | |
| Decimal('1.100000000000000088817841970012523233890533447265625') | |
| - collections.Counter() now supports a subtract() method. | |
| - The functools module now has a total_ordering() class decorator to simplify | |
| the specification of rich comparisons. | |
| - The functools module also adds cmp_to_key() as a tool to transition old-style | |
| comparison functions to new-style key-functions. | |
| - Issue #8294: The Fraction constructor now accepts Decimal and float instances | |
| directly. | |
| - Issue #7279: Comparisons involving a Decimal signaling NaN now signal | |
| InvalidOperation instead of returning False. (Comparisons involving a quiet | |
| NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal | |
| signaling NaNs remain unhashable. | |
| - Issue #2531: Comparison operations between floats and Decimal instances now | |
| return a result based on the numeric values of the operands; previously they | |
| returned an arbitrary result based on the relative ordering of id(float) and | |
| id(Decimal). | |
| - Issue #8233: When run as a script, py_compile.py optionally takes a single | |
| argument `-` which tells it to read files to compile from stdin. Each line is | |
| read on demand and the named file is compiled immediately. (Original patch by | |
| Piotr Ożarowski). | |
| - Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a | |
| function like a normal call. | |
| - Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and | |
| form feed (0x0C) are now considered linebreaks, as specified in Unicode | |
| Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/ | |
| - Comparisons using one of <, <=, >, >= between a complex instance and a | |
| Fractions instance now raise TypeError instead of returning True/False. This | |
| makes Fraction <=> complex comparisons consistent with int <=> complex, float | |
| <=> complex, and complex <=> complex comparisons. | |
| - Addition of ``WeakSet`` to the ``weakref`` module. | |
| - logging: Added LOG_FTP to SysLogHandler and updated documentation. | |
| - Issue #8205: Remove the "Modules" directory from sys.path when Python is | |
| running from the build directory (POSIX only). | |
| - Issue #7667: Fix doctest failures with non-ASCII paths. | |
| - Issue #7512: shutil.copystat() could raise an OSError when the filesystem | |
| didn't support chflags() (for example ZFS under FreeBSD). The error is now | |
| silenced. | |
| - Issue #7703: ctypes supports both buffer() and memoryview(). The former is | |
| deprecated. | |
| - Issue #7860: platform.uname now reports the correct 'machine' type when Python | |
| is running in WOW64 mode on 64 bit Windows. | |
| - logging: Added getChild utility method to Logger and added isEnabledFor method | |
| to LoggerAdapter. | |
| - Issue #8201: logging: Handle situation of non-ASCII and Unicode logger names | |
| existing at the same time, causing a Unicode error when configuration code | |
| attempted to sort the existing loggers. | |
| - Issue #8200: logging: Handle errors when multiprocessing is not fully loaded | |
| when logging occurs. | |
| - Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets. | |
| Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking | |
| reads and writes are always retried by OpenSSL itself. | |
| - Issue #8179: Fix macpath.realpath() on a non-existing path. | |
| - Issue #8024: Update the Unicode database to 5.2. | |
| - Issue #8104: socket.recv_into() and socket.recvfrom_into() now support writing | |
| into objects supporting the new buffer API, for example bytearrays or | |
| memoryviews. | |
| - Issue #4961: Inconsistent/wrong result of askyesno function in tkMessageBox | |
| with Tcl/Tk-8.5. | |
| - Issue #8140: Extend compileall to compile single files. Add -i option. | |
| - Issue #7774: Set sys.executable to an empty string if ``argv[0]`` has been set | |
| to a non existent program name and Python is unable to retrieve the real | |
| program name. | |
| - Issue #8117: logging: Improved algorithm for computing initial rollover time | |
| for ``TimedRotatingFileHandler`` by using the modification time of an existing | |
| log file to compute the next rollover time. If the log file does not exist, | |
| the current time is used as the basis for the computation. | |
| - Issue #6472: The ``xml.etree`` package is updated to ElementTree 1.3. The | |
| cElementTree module is updated too. | |
| - Issue #7880: Fix sysconfig when the python executable is a symbolic link. | |
| - Issue #7624: Fix ``isinstance(foo(), collections.Callable)`` for old-style | |
| classes. | |
| - Issue #7143: email: ``get_payload()`` used to strip any trailing newline from | |
| a base64 transfer-encoded payload *after* decoding it; it no longer does. | |
| This is a behavior change, so email's minor version number is now bumped, to | |
| version 4.0.2, for the 2.7 release. | |
| - Issue #8235: _socket: Add the constant ``SO_SETFIB``. SO_SETFIB is | |
| a socket option available on FreeBSD 7.1 and newer. | |
| - Issue #8038: unittest.TestCase.assertNotRegexpMatches | |
| - Addition of -b command line option to unittest for buffering stdout / stderr | |
| during test runs. | |
| - Issue #1220212: Added os.kill support for Windows, including support for | |
| sending CTRL+C and CTRL+BREAK events to console subprocesses. | |
| Extension Modules | |
| ----------------- | |
| - Issue #8314: Fix unsigned long long bug in libffi on Sparc v8. | |
| - Issue #1039, #8154: Fix os.execlp() crash with missing 2nd argument. | |
| - Issue #8156: bsddb module updated to version 4.8.4. | |
| http://www.jcea.es/programacion/pybsddb.htm#bsddb3-4.8.4. This update drops | |
| support for Berkeley DB 4.0, and adds support for 4.8. | |
| - Issue #3928: os.mknod() now available in Solaris, also. | |
| - Issue #8142: Update libffi to the 3.0.9 release. | |
| - Issue #8300: When passing a non-integer argument to struct.pack with any | |
| integer format code, struct.pack first attempts to convert the non-integer | |
| using its __index__ method. If that method is non-existent or raises | |
| TypeError it goes on to try the __int__ method, as described below. | |
| - Issue #1530559: When passing a non-integer argument to struct.pack with *any* | |
| integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the | |
| argument's __int__ method to convert to an integer before packing. It also | |
| produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was | |
| inconsistent: __int__ was used for some integer codes but not for others, and | |
| the set of integer codes for which it was used differed between native packing | |
| and standard packing.) | |
| - Issue #7347: _winreg: Add CreateKeyEx and DeleteKeyEx, as well as fix a bug in | |
| the return value of QueryReflectionKey. | |
| Tools/Demos | |
| ----------- | |
| - Issue #7993: Add a test of IO packet processing bandwidth to ccbench. It | |
| measures the number of UDP packets processed per second depending on the | |
| number of background CPU-bound Python threads. | |
| - python-config now supports multiple options on the same command line. | |
| Build | |
| ----- | |
| - Issue #8032: For gdb7, a python-gdb.py file is added to the build, allowing to | |
| use advanced gdb features when debugging Python. | |
| - Issue #1628484: The Makefile doesn't ignore the CFLAGS environment variable | |
| anymore. It also forwards the LDFLAGS settings to the linker when building a | |
| shared library. | |
| - Issue #6716: Quote -x arguments of compileall in MSI installer. | |
| - Issue #7705: Fix linking on FreeBSD. | |
| - Make sure that the FreeBSD build of the included libffi uses the proper | |
| assembly file. | |
| C-API | |
| ----- | |
| - Issue #8276: PyEval_CallObject() is now only available in macro form. The | |
| function declaration, which was kept for backwards compatibility reasons, is | |
| now removed (the macro was introduced in 1997!). | |
| - Issue #7992: A replacement PyCObject API, PyCapsule, has been backported from | |
| Python 3.1. All existing Python CObjects in the main distribution have been | |
| converted to capsules. To address backwards-compatibility concerns, | |
| PyCObject_AsVoidPtr() was changed to understand capsules. | |
| Tests | |
| ----- | |
| - Issue #3864: Skip three test_signal tests on freebsd6 because they fail if any | |
| thread was previously started, most likely due to a platform bug. | |
| - Issue #8348: Fix test ftp url in test_urllib2net. | |
| - Issue #8204: Fix test_ttk notebook test by forcing focus. | |
| - Issue #8344: Fix test_ttk bug on FreeBSD. | |
| - Issue #8193: Fix test_zlib failure with zlib 1.2.4. | |
| - Issue #8248: Add some tests for the bool type. Patch by Gregory Nofi. | |
| - Issue #8263: Now regrtest.py will report a failure if it receives a | |
| KeyboardInterrupt (SIGINT). | |
| - Issue #8180 and #8207: Fix test_pep277 on OS X and add more tests for special | |
| Unicode normalization cases. | |
| - Issue #7783: test.test_support.open_urlresource invalidates the outdated files | |
| from the local cache. | |
| What's New in Python 2.7 alpha 4? | |
| ================================= | |
| *Release date: 2010-03-06* | |
| Core and Builtins | |
| ----------------- | |
| - Issue #7544: Preallocate thread memory before creating the thread to avoid a | |
| fatal error in low memory condition. | |
| - Issue #7820: The parser tokenizer restores all bytes in the right if the BOM | |
| check fails. | |
| - Issue #7309: Fix unchecked attribute access when converting | |
| UnicodeEncodeError, UnicodeDecodeError, and UnicodeTranslateError to strings. | |
| - Issue #7649: "u'%c' % char" now behaves like "u'%s' % char" and raises a | |
| UnicodeDecodeError if 'char' is a byte string that can't be decoded using the | |
| default encoding. | |
| - Issue #6902: Fix problem with built-in types format incorrectly with 0 | |
| padding. | |
| - Issue #2560: Remove an unnecessary 'for' loop from ``my_fgets()`` in | |
| Parser/myreadline.c. | |
| - Issue #7988: Fix default alignment to be right aligned for | |
| ``complex.__format__``. Now it matches other numeric types. | |
| - Issue #5211: The complex type no longer uses implicit coercion in mixed-type | |
| binary arithmetic operations. | |
| Library | |
| ------- | |
| - Issue #7904: Changes to urllib.parse.urlsplit to handle schemes as defined by | |
| RFC3986. Anything before :// is considered a scheme and is followed by an | |
| authority (or netloc) and by '/' led path, which is optional. | |
| - Issue #1555570: email no longer inserts extra blank lines when a \r\n | |
| combo crosses an 8192 byte boundary. | |
| - Issue #6906: Tk should not set Unicode environment variables on Windows. | |
| - Issue #1054943: Fix ``unicodedata.normalize('NFC', text)`` for the Public | |
| Review Issue #29 (http://unicode.org/review/pr-29.html). | |

| wherever a Decimal instance is accepted, and implicitly convert that argument | |
| to Decimal. Previously only some arguments were converted. | |
| - Issue #6003: Add an argument to ``zipfile.Zipfile.writestr`` to specify the | |
| compression type. | |

| Xicluna who helped with the patch. | |
| Build | |
| ----- | |
| - Issue #3920, #7903: Define _BSD_SOURCE on OpenBSD 4.4 through 4.9. | |
| What's New in Python 2.7 alpha 3? | |
| ================================= | |
| *Release date: 2010-02-06* | |
| Core and Builtins | |
| ----------------- | |
| - Issue #5677: Explicitly forbid write operations on read-only file objects, | |
| and read operations on write-only file objects. On Windows, the system C | |
| library would return a bogus result; on Solaris, it was possible to crash the | |
| interpreter. Patch by Stefan Krah. | |
| - Issue #7853: Normalize exceptions before they are passed to a context | |
| manager's ``__exit__()`` method. | |
| - Issue #7385: Fix a crash in ``PyMemoryView_FromObject()`` when | |
| ``PyObject_GetBuffer()`` fails. Patch by Florent Xicluna. | |
| - Issue #7819: Check ``sys.call_tracing()`` arguments types. | |
| - Issue #7788: Fix an interpreter crash produced by deleting a list slice with | |
| very large step value. | |
| - Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple | |
| and add the additional members returned in an OSVERSIONINFOEX structure. The | |
| new members are service_pack_major, service_pack_minor, suite_mask, and | |
| product_type. | |
| - Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``) | |
| could crash in many places because of the ``PyByteArray_AS_STRING()`` macro | |
| returning NULL. The macro now returns a statically allocated empty string | |
| instead. | |
| - Issue #7622: Improve the split(), rsplit(), splitlines() and replace() | |
| methods of bytes, bytearray and unicode objects by using a common | |
| implementation based on stringlib's fast search. Patch by Florent Xicluna. | |
| - Issue #7632: Fix various str -> float conversion bugs present in 2.7 alpha 2, | |
| including: | |
| (1) a serious 'wrong output' bug that could occur for long (> 40 digit) input | |
| strings, | |
| (2) a crash in dtoa.c that occurred in debug builds when parsing certain long | |
| numeric strings corresponding to subnormal values, | |
| (3) a memory leak for some values large enough to cause overflow, and | |
| (4) a number of flaws that could lead to incorrectly rounded results. | |
| - Issue #7319, #7770: Silence ``DeprecationWarning`` by default when the -3 | |
| option is not used. | |
| - Issue #2335: Backport set literals syntax from Python 3.x. | |
| - Issue #2333: Backport set and dict comprehensions syntax from Python 3.x. | |
| - Issue #1967: Backport dictionary views from Python 3.x. | |
| Library | |
| ------- | |
| - Issue #9137: Fix issue in MutableMapping.update, which incorrectly | |
| treated keyword arguments called 'self' or 'other' specially. | |
| - Issue #7835: shelve should no longer produce mysterious warnings during | |
| interpreter shutdown. | |
| - Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">") in | |
| XML processing instructions and comments. These raw characters are allowed | |
| by the XML specification, and are necessary when outputting e.g. PHP code in | |
| a processing instruction. Patch by Neil Muller. | |
| - Issue #7869: logging: Improved diagnostic for format-time errors. | |
| - Issue #7868: logging: Added loggerClass attribute to Manager. | |
| - Issue #7851: logging: Clarification on logging configuration files. | |
| - Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is | |
| specified, rather than fall through to AF_PACKET (in the ``socket`` module). | |
| Also, raise ValueError rather than TypeError when an unknown TIPC address | |
| type is specified. Patch by Brian Curtin. | |
| - logging: Implemented PEP 391. | |
| - Issue #6939: Fix file I/O objects in the `io` module to keep the original | |
| file position when calling `truncate()`. It would previously change the file | |
| position to the given argument, which goes against the tradition of | |
| ftruncate() and other truncation APIs. Patch by Pascal Chambon. | |
| - Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile`` | |
| class used to represent files stored inside an archive. The new | |
| implementation is significantly faster and can be wrapped in an | |
| ``io.BufferedReader`` object for more speedups. It also solves an issue | |
| where interleaved calls to ``read()`` and ``readline()`` give wrong results. | |
| Patch by Nir Aides. | |
| - Issue #7792: Registering non-classes to ABCs raised an obscure error. | |
| - Removed the deprecated functions ``verify()`` and ``vereq()`` from | |
| Lib/test/test_support.py. | |
| - Issue #7773: Fix an UnboundLocalError in ``platform.linux_distribution()`` | |
| when the release file is empty. | |
| - Issue #7748: Since unicode values are supported for some metadata options in | |
| Distutils, the DistributionMetadata get_* methods will now return a utf-8 | |
| encoded string for them. This ensures that the upload and register commands | |
| send the correct values to PyPI without any error. | |
| - Issue #1670765: Prevent ``email.generator.Generator`` from re-wrapping | |
| headers in multipart/signed MIME parts, which fixes one of the sources of | |
| invalid modifications to such parts by Generator. | |
| - Issue #7701: Fix crash in ``binascii.b2a_uu()`` in debug mode when given a | |
| 1-byte argument. Patch by Victor Stinner. | |
| - Issue #3299: Fix possible crash in the _sre module when given bad argument | |
| values in debug mode. Patch by Victor Stinner. | |
| - Issue #7703: Add support for the new buffer API to functions of the binascii | |
| module. Backported from py3k by Florent Xicluna, with some additional tests. | |
| - Issue #2846: Add support for gzip.GzipFile reading zero-padded files. Patch | |
| by Brian Curtin. | |
| - Issue #5827: Make sure that normpath preserves unicode. Initial patch by | |
| Matt Giuca. | |
| - Issue #5372: Drop the reuse of .o files in Distutils' ccompiler (since | |
| Extension extra options may change the output without changing the .c file). | |
| Initial patch by Collin Winter. | |
| Extension Modules | |
| ----------------- | |
| - Expat: Fix DoS via XML document with malformed UTF-8 sequences | |
| (CVE_2009_3560). | |
| Build | |
| ----- | |
| - Issue #7632: When Py_USING_MEMORY_DEBUGGER is defined, disable the private | |
| memory allocation scheme in dtoa.c and use PyMem_Malloc and PyMem_Free | |
| instead. Also disable caching of powers of 5. | |
| - Issue #7658: Ensure that the new pythonw executable works on OSX 10.4 | |
| - Issue #7714: Use ``gcc -dumpversion`` to detect the version of GCC on | |
| MacOSX. | |
| - Issue #7661: Allow ctypes to be built from a non-ASCII directory path. | |
| Patch by Florent Xicluna. | |
| Tools/Demos | |
| ----------- | |
| - iobench (a file I/O benchmark) and ccbench (a concurrency benchmark) were | |
| added to the ``Tools`` directory. They were previously living in the | |
| sandbox. | |
| Tests | |
| ----- | |
| - Issue #7728: test_timeout was changed to use ``test_support.bind_port()`` | |
| instead of a hard coded port. | |
| Documentation | |
| ------------- | |
| - Updated "Using Python" documentation to include description of CPython's -J, | |
| -U and -X options. | |
| - Updated Python manual page (options -B, -O0, -s, environment variables | |
| PYTHONDONTWRITEBYTECODE, PYTHONNOUSERSITE). | |
| What's New in Python 2.7 alpha 2? | |
| ================================= | |
| *Release date: 2010-01-09* | |
| Core and Builtins | |
| ----------------- | |
| - The ``__complex__()`` method is now looked up on the class of instances to | |
| make it consistent with other special methods. | |
| - Issue #7462: Implement the stringlib fast search algorithm for the `rfind`, | |
| `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna. | |
| - Issue #5080: A number of functions and methods previously produced a | |
| DeprecationWarning when passed a float argument where an integer was expected. | |
| These functions and methods now raise TypeError instead. The majority of the | |
| effects of this change are in the extension modules, but some core functions | |
| and methods are affected: notably the 'chr', 'range' and 'xrange' builtins, | |
| and many unicode/str methods. | |
| - Issue #7604: Deleting an unset slotted attribute did not raise an | |
| AttributeError. | |
| - Issue #7534: Fix handling of IEEE specials (infinities, nans, negative zero) | |
| in ** operator. The behaviour now conforms to that described in C99 Annex F. | |
| - Issue #7579: The msvcrt module now has docstrings for all its functions. | |
| - Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat() | |
| used to drop the time part of the result. | |
| - Issue #1811: Improve accuracy and cross-platform consistency for true division | |
| of integers: the result of a/b is now correctly rounded for ints a and b (at | |
| least on IEEE 754 platforms), and in particular does not depend on the | |
| internal representation of a long. | |
| - Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the | |
| same message when only ``__str__()`` (and not ``__unicode__()``) is overridden | |
| in the subclass. | |
| - Issue #6834: Replace the implementation for the 'python' and 'pythonw' | |
| executables on OSX. | |
| These executables now work properly with the arch(1) command: ``arch -ppc | |
| python`` will start a universal binary version of python in PPC mode (unlike | |
| previous releases). | |
| - Issue #1680159: Unicode coercion during an 'in' operation no longer masks the | |
| underlying error when the coercion fails for the left hand operand. | |
| - Issue #7491: Metaclass's __cmp__ method was ignored. | |
| - Issue #7466: Segmentation fault when the garbage collector is called in the | |
| middle of populating a tuple. Patch by Florent Xicluna. | |
| Library | |
| ------- | |
| - Issue #6963: Added "maxtasksperchild" argument to ``multiprocessing.Pool``, | |
| allowing for a maximum number of tasks within the pool to be completed by the | |
| worker before that worker is terminated, and a new one created to replace it. | |
| - Issue #7617: Make sure distutils.unixccompiler.UnixCCompiler recognizes gcc | |
| when it has a fully qualified configuration prefix. Initial patch by | |
| Arfrever. | |
| - Issue #7092: Remove py3k warning when importing cPickle. 2to3 handles | |
| renaming of `cPickle` to `pickle`. The warning was annoying since there's no | |
| alternative to cPickle if you care about performance. Patch by Florent | |
| Xicluna. | |
| - Issue #7455: Fix possible crash in cPickle on invalid input. Patch by Victor | |
| Stinner. | |
| - Issue #7092: Fix the DeprecationWarnings emitted by the standard library when | |
| using the -3 flag. Patch by Florent Xicluna. | |
| - Issue #7471: Improve the performance of GzipFile's buffering mechanism, and | |
| make it implement the ``io.BufferedIOBase`` ABC to allow for further speedups | |
| by wrapping it in an ``io.BufferedReader``. Patch by Nir Aides. | |
| - Issue #3972: ``httplib.HTTPConnection`` now accepts an optional source_address | |
| parameter to allow specifying where your connections come from. | |
| - ``socket.create_connection()`` now accepts an optional source_address | |
| parameter. | |
| - Issue #5511: ``zipfile.ZipFile`` can now be used as a context manager. | |
| Initial patch by Brian Curtin. | |
| - Distutils now correctly identifies the build architecture as "x86_64" when | |
| building on OSX 10.6 without "-arch" flags. | |
| - Issue #7556: Distutils' msvc9compiler now opens the MSVC Manifest file in text | |
| mode. | |
| - Issue #7552: Removed line feed in the base64 Authorization header in the | |
| Distutils upload command to avoid an error when PyPI reads it. This occurs on | |
| long passwords. Initial patch by JP St. Pierre. | |
| - Issue #7231: urllib2 cannot handle https with proxy requiring auth. Patch by | |
| Tatsuhiro Tsujikawa. | |
| - Issue #7349: Make methods of file objects in the io module accept None as an | |
| argument where file-like objects (ie StringIO and BytesIO) accept them to mean | |
| the same as passing no argument. | |
| - Issue #7348: ``StringIO.StringIO.readline(-1)`` now acts as if it got no | |
| argument like other file objects. | |
| - Issue #7357: tarfile no longer suppresses fatal extraction errors by default. | |
| - Issue #7470: logging: Fix bug in Unicode encoding fallback. | |
| - Issue #5949: Fixed IMAP4_SSL hang when the IMAP server response is missing | |
| proper end-of-line termination. | |
| - Issue #7457: Added a read_pkg_file method to | |
| ``distutils.dist.DistributionMetadata``. | |
| - Issue #3745: Undo the 2.7a1 change to have hashlib to reject unicode and non | |
| buffer API supporting objects as input. That behavior is for 3.x only. | |
| C-API | |
| ----- | |
| - Issue #7767: New function ``PyLong_AsLongLongAndOverflow()`` added, analogous | |
| to ``PyLong_AsLongAndOverflow()``. | |
| - Issue #5080: The argument parsing functions ``PyArg_ParseTuple()``, | |
| ``PyArg_ParseTupleAndKeywords()``, ``PyArg_VaParse()``, | |
| ``PyArg_VaParseTupleAndKeywords()`` and ``PyArg_Parse()`` no longer accept | |
| float arguments for integer format codes (other than 'L'): previously an | |
| attempt to pass a float resulted in a DeprecationWarning; now it gives a | |
| TypeError. For the 'L' format code (which previously had no warning) there is | |
| now a DeprecationWarning. | |
| - Issue #7033: Function ``PyErr_NewExceptionWithDoc()`` added. | |
| Build | |
| ----- | |
| - Issue #6491: Allow --with-dbmliborder to specify that no dbms will be built. | |
| - Issue #6943: Use pkg-config to find the libffi headers when the | |
| ``--with-system-ffi`` flag is used. | |
| - Issue #7609: Add a ``--with-system-expat`` option that causes the system's | |
| expat library to be used for the pyexpat module instead of the one included | |
| with Python. | |
| - Issue #7589: Only build the nis module when the correct header files are | |
| found. | |
| - Switch to OpenSSL 0.9.8l and sqlite 3.6.21 on Windows. | |
| - Issue #7541: when using ``python-config`` with a framework install the | |
| compiler might use the wrong library. | |
| Tests | |
| ----- | |
| - Issue #7376: Instead of running a self-test (which was failing) when called | |
| with no arguments, doctest.py now gives a usage message. | |
| - Issue #7396: Fix regrtest -s, which was broken by the -j enhancement. | |
| - Issue #7498: test_multiprocessing now uses test_support.find_unused_port | |
| instead of a hardcoded port number in test_rapid_restart. | |
| What's New in Python 2.7 alpha 1 | |
| ================================ | |
| *Release date: 2009-12-05* | |
| Core and Builtins | |
| ----------------- | |
| - Issue #7419: ``locale.setlocale()`` could crash the interpreter on Windows | |
| when called with invalid values. | |
| - Issue #3382: 'F' formatting for float and complex now convert the result to | |
| upper case. This only affects 'inf' and 'nan', since 'f' no longer converts | |
| to 'g' for large values. | |
| - Remove switch from "%f" formatting to "%g" formatting for floats larger than | |
| 1e50 in absolute value. | |
| - Remove restrictions on precision when formatting floats. E.g., "%.120g" % | |
| 1e-100 used to raise OverflowError, but now gives the requested 120 | |
| significant digits instead. | |
| - Add Py3k warnings for parameter names in parentheses. | |
| - Issue #7362: Give a proper error message for ``def f((x)=3): pass``. | |
| - Issue #7085: Fix crash when importing some extensions in a thread on MacOSX | |
| 10.6. | |
| - Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest | |
| decimal string that's guaranteed to round back to x under correct rounding | |
| (with round-half-to-even rounding mode). Previously it gave a string based on | |
| rounding x to 17 decimal digits. repr(x) for a complex number behaves | |
| similarly. On platforms where the correctly-rounded strtod and dtoa code is | |
| not supported (see below), repr is unchanged. | |
| - Issue #7117: On almost all platforms: float-to-string and string-to-float | |
| conversions within Python are now correctly rounded. Places these conversions | |
| occur include: str for floats and complex numbers; the float and complex | |
| constructors; old-style and new-style numeric formatting; serialization and | |
| deserialization of floats and complex numbers using marshal, pickle and json; | |
| parsing of float and imaginary literals in Python code; Decimal-to-float | |
| conversion. | |
| The conversions use a Python-adapted version of David Gay's well-known dtoa.c, | |
| providing correctly-rounded strtod and dtoa C functions. This code is | |
| supported on Windows, and on Unix-like platforms using gcc, icc or suncc as | |
| the C compiler. There may be a small number of platforms on which correct | |
| operation of this code cannot be guaranteed, so the code is not used: notably, | |
| this applies to platforms where the C double format is not IEEE 754 binary64, | |
| and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision | |
| and Python's configure script is unable to determine how to change the FPU | |
| precision. On these platforms conversions use the platform strtod and dtoa, | |
| as before. | |
| - Issue #7117: Backport round implementation from Python 3.x. ``round()`` now | |
| uses the correctly-rounded string <-> float conversions described above (when | |
| available), and so produces correctly rounded results that will display nicely | |
| under the float repr. There are two related small changes: (1) round now | |
| accepts any class with an ``__index__()`` method for its second argument (but | |
| no longer accepts floats for the second argument), and (2) an excessively | |
| large second integer argument (e.g., ``round(1.234, 10**100)``) no longer | |
| raises an exception. | |
| - Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding. | |
| - Fix several issues with ``compile()``. The input can now contain Windows and | |
| Mac newlines and is no longer required to end in a newline. | |
| - Remove length limitation when constructing a complex number from a unicode | |
| string. | |
| - Issue #7244: ``itertools.izip_longest()`` no longer ignores exceptions raised | |
| during the formation of an output tuple. | |
| - Issue #1087418: Boost performance of bitwise operations for longs. | |
| - Issue #1722344: ``threading._shutdown()`` is now called in ``Py_Finalize()``, | |
| which fixes the problem of some exceptions being thrown at shutdown when the | |
| interpreter is killed. Patch by Adam Olsen. | |
| - Issue #7168: Document ``PyFloat_AsString()`` and ``PyFloat_AsReprString()``, | |
| and note that they are unsafe and deprecated. | |
| - Issue #7120: logging: Remove import of multiprocessing which is causing crash | |
| in GAE. | |
| - Issue #7140: The ``__dict__`` of a module should not be cleared unless the | |
| module is the only object holding a reference to it. | |
| - Issue #1754094: Improve the stack depth calculation in the compiler. There | |
| should be no other effect than a small decrease in memory use. Patch by | |
| Christopher Tur Lesniewski-Laas. | |
| - Issue #7084: Fix a (very unlikely) crash when printing a list from one thread, | |
| and mutating it from another one. Patch by Scott Dial. | |
| - Issue #1571184: The Unicode database contains properties for more characters. | |
| The tables for code points representing numeric values, white spaces or line | |
| breaks are now generated from the official Unicode Character Database files, | |
| and include information from the Unihan.txt file. | |
| - Issue #7050: Fix a SystemError when trying to use unpacking and augmented | |
| assignment. | |
| - Issue #5329: Fix ``os.popen*`` regression from 2.5 with commands as a sequence | |
| running through the shell. Patch by Jean-Paul Calderone and Jani Hakala. | |
| - Issue #7019: Raise ValueError when unmarshalling bad long data, instead of | |
| producing internally inconsistent Python longs. | |
| - Issue #6990: Fix ``threading.local`` subclasses leaving old state around after | |
| a reference cycle GC which could be recycled by new locals. | |
| - Issue #6300: unicode.encode, unicode.decode, str.decode, and str.encode now | |
| take keyword arguments. | |
| - Issue #6922: Fix an infinite loop when trying to decode an invalid UTF-32 | |
| stream with a non-raising error handler like "replace" or "ignore". | |
| - Issue #6713: Improve performance of base 10 int -> string and long -> string | |
| conversions. | |
| - Issue #1590864: Fix potential deadlock when mixing threads and fork(). | |
| - Issue #6844: Do not emit DeprecationWarnings when accessing a "message" | |
| attribute on exceptions that was set explicitly. | |
| - Issue #6846: Fix bug where bytearray.pop() returns negative integers. | |
| - ``classmethod()`` no longer checks if its argument is callable. | |
| - Issue #6750: A text file opened with ``io.open()`` could duplicate its output | |
| when writing from multiple threads at the same time. | |
| - Issue #6704: Improve the col_offset in AST for "for" statements with a target | |
| of tuple unpacking. | |
| - Issue #6707: ``dir()`` on an uninitialized module caused a crash. | |
| - Issue #6540: Fixed crash for ``bytearray.translate()`` with invalid parameters. | |
| - Issue #6573: ``set.union()`` stopped processing inputs if an instance of self | |
| occurred in the argument chain. | |
| - Issue #1616979: Added the cp720 (Arabic DOS) encoding. | |
| - Issue #6070: On posix platforms import no longer copies the execute bit from | |
| the .py file to the .pyc file if it is set. Patch by Marco N. | |
| - Issue #4618: When unicode arguments are passed to ``print()``, the default | |
| separator and end should be unicode also. | |
| - Issue #6119: Fixed an incorrect Py3k warning about order comparisons of | |
| built-in functions and methods. | |
| - Issue #6347: Include inttypes.h as well as stdint.h in pyport.h. This fixes a | |
| build failure on HP-UX: int32_t and uint32_t are defined in inttypes.h instead | |
| of stdint.h on that platform. | |
| - Issue #4856: Remove checks for win NT. | |
| - Issue #2016: Fixed a crash in a corner case where the dictionary of keyword | |
| arguments could be modified during the function call setup. | |
| - Removed the ipaddr module. | |
| - Issue #6329: Fixed iteration for memoryview objects (it was being blocked | |
| because it wasn't recognized as a sequence). | |
| - Issue #6289: Encoding errors from ``compile()`` were being masked. | |
| - When no module is given in a relative import, the module field of the | |
| ImportFrom AST node is now None instead of an empty string. | |
| - Assignment to None using import statements now raises a SyntaxError. | |
| - Issue #4547: When debugging a very large function, it was not always possible | |
| to update the lineno attribute of the current frame. | |
| - Issue #5330: C functions called with keyword arguments were not reported by | |
| the various profiling modules (profile, cProfile). Patch by Hagen Fürstenau. | |
| - Issue #5982: staticmethod and classmethod now expose the wrapped function with | |
| ``__func__``. | |
| - Added support for multiple context managers in the same with-statement. | |
| Deprecated ``contextlib.nested()`` which is no longer needed. | |
| - Issue #6101: A new opcode, SETUP_WITH, has been added to speed up the with | |
| statement and correctly lookup the __enter__ and __exit__ special methods. | |
| - Issue #5829: complex("1e500") no longer raises OverflowError. This makes it | |
| consistent with float("1e500") and interpretation of real and imaginary | |
| literals. | |
| - Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more. | |
| - ``__instancecheck__()`` and ``__subclasscheck__()`` are now completely ignored | |
| on classic classes and instances. | |
| - Issue #5994: The marshal module now has docstrings. | |
| - Issue #5981: Fix three minor inf/nan issues in float.fromhex: | |
| (1) inf and nan strings with trailing whitespace were incorrectly rejected; | |
| (2) parsing of strings representing infinities and nans was locale aware; and | |
| (3) the interpretation of fromhex('-nan') didn't match that of float('-nan'). | |
| - Issue #5920: For ``float.__format__()``, change the behavior with the empty | |
| presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g' | |
| but with at least one decimal point and with a default precision | |
| of 12. Previously, the behavior the same but with a default precision of 6. | |
| This more closely matches ``str()``, and reduces surprises when adding | |
| alignment flags to the empty presentation type. This also affects the new | |
| complex.__format__ in the same way. | |
| - Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by | |
| classtype's, even if it was None. property now inserts the __doc__ into the | |
| subclass instance __dict__. | |
| - Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal | |
| sequences. Patch by Nick Barnes and Victor Stinner. | |
| - Issue #1588: Add complex.__format__. For example, ``format(complex(1, 2./3), | |
| '.5')`` now produces a sensible result. | |
| - Issue #5864: Fix empty format code formatting for floats so that it never | |
| gives more than the requested number of significant digits. | |
| - Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes new | |
| Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h. | |
| - Issue #4971: Fix titlecase for characters that are their own titlecase, but | |
| not their own uppercase. | |
| - Issue #5835: Deprecate PyOS_ascii_formatd and replace it with | |
| _PyOS_double_to_string or PyOS_double_to_string. | |
| - Issue #5283: Setting __class__ in __del__ caused a segfault. | |
| - Issue #5816: ``complex(repr(z))`` now recovers z exactly, even when z involves | |
| nans, infs or negative zeros. | |
| - Implement PEP 378, Format Specifier for Thousands Separator, for floats, ints, | |
| and longs. | |
| - Issue #5515: 'n' formatting for ints, longs, and floats handles leading zero | |
| formatting poorly. | |
| - Issue #5772: For float.__format__, don't add a trailing ".0" if we're using no | |
| type code and we have an exponent. | |
| - Issue #3166: Make long -> float (and int -> float) conversions correctly | |
| rounded. | |
| - Issue #5787: ``object.__getattribute__(some_type, "__bases__")`` segfaulted on | |
| some built-in types. | |
| - Issue #1869: Fix a couple of minor round() issues. ``round(5e15+1)`` was | |
| giving 5e15+2; ``round(-0.0)`` was losing the sign of the zero. | |
| - Issue #5759: float() didn't call __float__ on str subclasses. | |
| - Issue #5704: The "-3" command-line option now implies "-t". | |
| - Issue #2170: Refactored ``xml.dom.minidom.normalize``, increasing both its | |
| clarity and its speed. | |
| - Issue #2396: The memoryview object was backported from Python 3.1. | |
| - Fix a problem in PyErr_NormalizeException that leads to "undetected errors" | |
| when hitting the recursion limit under certain circumstances. | |
| - Issue #1665206: Remove the last eager import in _warnings.c and make it lazy. | |
| - Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to the end | |
| sys.path, for compatibility with the system install of Python. | |
| - Issue #4688: Add a heuristic so that tuples and dicts containing only | |
| untrackable objects are not tracked by the garbage collector. This can reduce | |
| the size of collections and therefore the garbage collection overhead on | |
| long-running programs, depending on their particular use of datatypes. | |
| - Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to improve its | |
| performance. Long divisions and remainder operations are now between 50% and | |
| 150% faster. | |
| - Issue #4258: Make it possible to use base 2**30 instead of base 2**15 for the | |
| internal representation of integers, for performance reasons. Base 2**30 is | |
| enabled by default on 64-bit machines. Add --enable-big-digits option to | |
| configure, which overrides the default. Add sys.long_info structseq to | |
| provide information about the internal format. | |
| - Issue #4034: Fix weird attribute error messages of the traceback object. (As a | |
| result traceback.__members__ no longer exists.) | |
| - Issue #4474: PyUnicode_FromWideChar now converts characters outside the BMP to | |
| surrogate pairs, on systems with sizeof(wchar_t) == 4 and sizeof(Py_UNICODE) | |
| == 2. | |
| - Issue #5237: Allow auto-numbered fields in str.format(). For example: ``'{} | |
| {}'.format(1, 2) == '1 2'``. | |
| - Issue #3652: Make the 'line' argument for ``warnings.showwarning()`` a | |
| requirement. Means the DeprecationWarning from Python 2.6 can go away. | |
| - Issue #5247: Improve error message when unknown format codes are used when | |
| using ``str.format()`` with str, unicode, long, int, and float arguments. | |
| - Running Python with the -3 option now also warns about classic division for | |
| ints and longs. | |
| - Issue #5260: Long integers now consume less memory: average saving is 2 bytes | |
| per long on a 32-bit system and 6 bytes per long on a 64-bit system. | |
| - Issue #5186: Reduce hash collisions for objects with no __hash__ method by | |
| rotating the object pointer by 4 bits to the right. | |
| - Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs: it now | |
| forces its argument to double before testing for infinity. | |
| - Issue #4978: Passing keyword arguments as unicode strings is now allowed. | |
| - Issue #1242657: the __len__() and __length_hint__() calls in several tools | |
| were suppressing all exceptions. These include list(), filter(), map(), | |
| zip(), and bytearray(). | |
| - os.ftruncate raises OSErrors instead of IOErrors for consistency with other os | |
| functions. | |
| - Issue #4991: Passing invalid file descriptors to io.FileIO now raises an | |
| OSError. | |
| - Issue #4807: Port the _winreg module to Windows CE. | |
| - Issue #4935: The overflow checking code in the expandtabs() method common to | |
| str, bytes and bytearray could be optimized away by the compiler, letting the | |
| interpreter segfault instead of raising an error. | |
| - Issue #3720: Fix a crash when an iterator modifies its class and removes its | |
| __next__ method. | |
| - Issue #4893: Use NT threading on CE. | |
| - Issue #4915: Port sysmodule to Windows CE. | |
| - Issue #4074: Change the criteria for doing a full garbage collection (i.e. | |
| collecting the oldest generation) so that allocating lots of objects without | |
| destroying them does not show quadratic performance. Based on a proposal by | |
| Martin von Löwis at | |
| http://mail.python.org/pipermail/python-dev/2008-June/080579.html. | |
| - Issue #4850: Change COUNT_ALLOCS variables to Py_ssize_t. | |
| - Issue #1180193: When importing a module from a .pyc (or .pyo) file with an | |
| existing .py counterpart, override the co_filename attributes of all code | |
| objects if the original filename is obsolete (which can happen if the file has | |
| been renamed, moved, or if it is accessed through different paths). Patch by | |
| Ziga Seilnacht and Jean-Paul Calderone. | |
| - Issue #4075: Use ``OutputDebugStringW()`` in Py_FatalError. | |
| - Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open | |
| file with `str' filename on Windows. | |
| - Issue #3680: Reference cycles created through a dict, set or deque iterator | |
| did not get collected. | |
| - Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types where | |
| the tp_hash and tp_dict slots are both NULL. | |
| - Issue #4764: With io.open, IOError.filename is set when trying to open a | |
| directory on POSIX systems. | |
| - Issue #4764: IOError.filename is set when trying to open a directory on POSIX | |
| systems. | |
| - Issue #4759: None is now allowed as the first argument of | |
| ``bytearray.translate()``. It was always allowed for ``bytes.translate()``. | |
| - Added test case to ensure attempts to read from a file opened for writing | |
| fail. | |
| - Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always print | |
| elapsed times, not only when some objects are uncollectable/unreachable. | |
| Original patch by Neil Schemenauer. | |
| - Issue #3439: Add a bit_length method to int and long. | |
| - Issue #2183: Simplify and optimize bytecode for list comprehensions. Original | |
| patch by Neal Norwitz. | |
| - Issue #4597: Fixed exception handling when the __exit__ function of a context | |
| manager returns a value that cannot be converted to a bool. | |
| - Issue #4597: Fixed several opcodes that weren't always propagating exceptions. | |
| - Issue #4445: Replace ``sizeof(PyStringObject)`` with | |
| ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str | |
| instances. On a typical machine this saves 3 bytes of memory (on average) per | |
| string allocation. | |
| - Issue #3996: On Windows, the PyOS_CheckStack function would cause the | |
| interpreter to abort ("Fatal Python error: Could not reset the stack!") | |
| instead of throwing a MemoryError. | |
| - Issue #3689: The list reversed iterator now supports __length_hint__ instead | |
| of __len__. Behavior now matches other reversed iterators. | |
| - Issue #4367: Python would segfault during compiling when the unicodedata | |
| module couldn't be imported and \N escapes were present. | |
| - Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on | |
| file objects with closefd=False. The file descriptor is still kept open but | |
| the file object behaves like a closed file. The ``FileIO`` object also got a | |
| new readonly attribute ``closefd``. | |
| - Issue #4348: Some bytearray methods returned that didn't cause any change to | |
| the bytearray, returned the same bytearray instead of a copy. | |
| - Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function. | |
| - Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly. | |
| - Issue #4048: The parser module now correctly validates relative imports. | |
| - Issue #4225: ``from __future__ import unicode_literals`` didn't work in an | |
| exec statement. | |
| - Issue #4176: Fixed a crash when pickling an object which ``__reduce__`` method | |
| does not return iterators for the 4th and 5th items. | |
| - Issue #4209: Enabling unicode_literals and the print_function in the same | |
| __future__ import didn't work. | |
| - Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning | |
| because it is a reserved word in 3.x. | |
| - On windows, ``os.chdir()`` given unicode was not working if | |
| GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful | |
| this code path is really executed because I cannot move to such directory on | |
| win2k) | |
| - Issue #4069: When ``set.remove(element)`` is used with a set element, the | |
| element is temporarily replaced with an equivalent frozenset. But the | |
| eventual KeyError would always report the empty ``frozenset()`` as the missing | |
| key. Now it correctly refers to the initial element. | |
| - Issue #4509: Various issues surrounding resize of bytearray objects to which | |
| there are buffer exports. | |
| - Issue #4748: Lambda generators no longer return a value. | |
| - Issue #3582: Use native TLS functions on Windows | |
| - The re.sub(), re.subn() and re.split() functions now accept a flags parameter. | |
| - Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with short | |
| file names. | |
| - Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)' | |
| to avoid compiler warnings. | |
| - Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam() | |
| returned them on 64bit platforms. | |
| - Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call | |
| PyUnicode_DecodeUTF8() once, remember the result and output it in a second | |
| step. This avoids problems with counting UTF-8 bytes that ignores the effect | |
| of using the replace error handler in PyUnicode_DecodeUTF8(). | |
| - Issue #3739: The unicode-internal encoder now reports the number of characters | |
| consumed like any other encoder (instead of the number of bytes). | |
| - Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc | |
| allocator will be automatically disabled when running under Valgrind. This | |
| gives improved memory leak detection when running under Valgrind, while taking | |
| advantage of pymalloc at other times. | |
| Library | |

| Patch by Jean-Paul Calderone. | |
| - Issue #7408: Fixed distutils.tests.sdist so it doesn't check for group | |
| ownership when the group is not forced, because the group may be different | |
| from the user's group and inherit from its container when the test is run. | |
| - Issue #1515: Enable use of deepcopy() with instance methods. Patch by Robert | |
| Collins. | |
| - Issue #7403: logging: Fixed possible race condition in lock creation. | |

| or SSL. Patch by Giampaolo Rodola'. | |
| - Issue #4969: The mimetypes module now reads the MIME database from the | |
| registry under Windows. Patch by Gabriel Genellina. | |
| - Issue #6816: runpy now provides a run_path function that allows Python code to | |
| execute file paths that refer to source or compiled Python files as well as | |
| zipfiles, directories and other valid sys.path entries that contain a | |
| __main__.py file. This allows applications that run other Python scripts to | |
| support the same flexibility as the CPython command line itself. | |
| - Issue #7318: multiprocessing now uses a timeout when it fails to establish a | |
| connection with another process, rather than looping endlessly. The default | |
| timeout is 20 seconds, which should be amply sufficient for local connections. | |
| - Issue #7197: Allow unittest.TextTestRunner objects to be pickled and | |
| unpickled. This fixes crashes under Windows when trying to run | |
| test_multiprocessing in verbose mode. | |

| which are part of a reference cycle. | |
| - Issue #7211: Allow 64-bit values for the ``ident`` and ``data`` fields of | |
| kevent objects on 64-bit systems. Patch by Michael Broghton. | |
| - Issue #6896: ``mailbox.Maildir`` now invalidates its internal cache each time | |
| a modification is done through it. This fixes inconsistencies and test | |
| failures on systems with slightly bogus mtime behaviour. | |
| - Issue #7246 & Issue #7208: getpass now properly flushes input before reading | |
| from stdin so that existing input does not confuse it and lead to incorrect | |
| entry or an IOError. It also properly flushes it afterwards to avoid the | |
| terminal echoing the input afterwards on OSes such as Solaris. | |
| - Issue #7233: Fix a number of two-argument Decimal methods to make sure that | |
| they accept an int or long as the second argument. Also fix buggy handling of | |
| large arguments (those with coefficient longer than the current precision) in | |
| shift and rotate. | |
| - Issue #4750: Store the basename of the original filename in the gzip FNAME | |
| header as required by RFC 1952. | |

| Distutils. | |
| - Issue #7218: Fix test_site for win32, the directory comparison was done with | |
| an uppercase. | |
| - Issue #7205: Fix a possible deadlock when using a BZ2File object from several | |
| threads at once. | |
| - Issue #7071: byte-compilation in Distutils is now done with respect to | |
| sys.dont_write_bytecode. | |

| - Issue #7086: Added TCP support to SysLogHandler, and tidied up some | |
| anachronisms in the code which were a relic of 1.5.2 compatibility. | |
| - Issue #7082: When falling back to the MIME 'name' parameter, the correct place | |
| to look for it is the Content-Type header. | |
| - Issue #7048: Force Decimal.logb to round its result when that result is too | |
| large to fit in the current precision. | |

| type specifier. | |
| - Issue #4937: plat-mac/bundlebuilder refers to non-existing version.plist. | |
| - Issue #6838: Use a list to accumulate the value instead of repeatedly | |
| concatenating strings in httplib's HTTPResponse._read_chunked providing a | |
| significant speed increase when downloading large files servend with a | |
| Transfer-Encoding of 'chunked'. | |
| - Issue #5275: In Cookie's Cookie.load(), properly handle non-string arguments | |
| as documented. | |
| - Issue #2666: Handle BROWSER environment variable properly for unknown browser | |
| names in the webbrowser module. | |
| - Issue #6054: Do not normalize stored pathnames in tarfile. | |
| - Issue #6794: Fix Decimal.compare_total and Decimal.compare_total_mag: NaN | |
| payloads are now ordered by integer value rather than lexicographically. | |

| - Issue #6629: Fix a data corruption issue in the new `io` package, which could | |
| occur when writing to a BufferedRandom object (e.g. a file opened in "rb+" or | |
| "wb+" mode) after having buffered a certain amount of data for reading. This | |
| bug was not present in the pure Python implementation. | |
| - Issue #4660: If a multiprocessing.JoinableQueue.put() was preempted, it was | |
| possible to get a spurious 'task_done() called too many times' error. | |
| - Issue #1628205: Socket file objects returned by socket.socket.makefile() now | |
| properly handles EINTR within the read, readline, write & flush methods. The | |
| socket.sendall() method now properly handles interrupted system calls. | |
| - Issue #6595: The Decimal constructor now allows arbitrary Unicode decimal | |
| digits in input, as recommended by the standard. Previously it was restricted | |
| to accepting [0-9]. | |
| - Issue #6511: ZipFile now raises BadZipfile (instead of an IOError) when | |
| opening an empty or very small file. | |
| - Issue #6553: Fixed a crash in cPickle.load(), when given a file-like object | |
| containing incomplete data. | |
| - Issue #6545: Removed assert statements in distutils.Extension, so the behavior | |
| is similar when used with -O. | |
| - unittest has been split up into a package. All old names should still work. | |

| output compared to previous Python versions. | |
| - Issue #1034053: unittest now supports skipping tests and expected failures. | |
| - The unittest.TestCase.assertRaises() method now returns a context manager when | |
| not given a callable so that code to be tested can be written inline using a | |
| with statement. | |
| - Issue #2578: The unittest.TestCase.assertEqual() now displays the differences | |
| in lists, tuples, dicts and sets on failure. Many new handy type and | |
| comparison specific assert* methods have been added that fail with error | |
| messages actually useful for debugging. Contributed in part by Google. | |
| - Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop forever | |
| on incomplete input. That caused tarfile.open() to hang when used with mode | |
| 'r' or 'r:bz2' and a fileobj argument that contained no data or partial bzip2 | |
| compressed data. | |
| - Issue #5536: urllib.urlretrieve makes sure to close the file it's writing to | |
| even if an exception occurs. | |

| disabled, and not compiled. | |
| - Issue #5008: When a file is opened in append mode with the new IO library, do | |
| an explicit seek to the end of file (so that e.g. tell() returns the file size | |
| rather than 0). This is consistent with the behaviour of the traditional 2.x | |
| file object. | |

| parameter was set. | |
| - Issue #4998: The memory saving effect of __slots__ had been lost on Fractions | |

| Belopolsky. | |
| - Issue #4197: Doctests in modules loaded via zipimport (or any other PEP 302 | |
| conformant loader) will now work correctly in most cases (they are still | |
| subject to the constraints that exist for all code running from inside a | |

| based on __file__). Original patch by Alexander Belopolsky. | |
| - Issues #4082 and #4512: Add runpy support to zipimport in a manner that allows | |

| Build | |
| ----- | |
| - Issue #6603: Change READ_TIMESTAMP macro in ceval.c so that it compiles | |
| correctly under gcc on x86-64. This fixes a reported problem with the | |
| --with-tsc build on x86-64. | |
| - Add 2 new options to ``--with-universal-archs`` on MacOSX: ``intel`` builds a | |
| distribution with ``i386`` and ``x86_64`` architectures, while ``3-way`` | |
| builds a distribution with the ``ppc``, ``i386`` and ``x86_64`` architectures. | |

| ----- | |
| - Issue #7528: Add PyLong_AsLongAndOverflow (backported from py3k). | |
| - Issue #7228: Add '%lld' and '%llu' support to PyString_FromFormat(V) and | |
| PyErr_Format, on machines with HAVE_LONG_LONG defined. | |
| - Add new C-API function PyOS_string_to_double, and deprecated PyOS_ascii_atof | |
| and PyOS_ascii_strtod. | |
| - Removed _PyOS_double_to_string. Use PyOS_double_to_string instead. This is in | |
| preparation for (but not strictly related to) issue #7117, short float repr. | |
| - Issue #6624: PyArg_ParseTuple with "s" format when parsing argument with NULL: | |
| Bogus TypeError detail string. | |
| - Issue #5954: Add a PyFrame_GetLineNumber() function to replace most uses of | |
| PyCode_Addr2Line(). | |
| - Issue #5959: Add a PyCode_NewEmpty() function to create a new empty code | |
| object at a specified file, function, and line number. | |
| - Issue #1419652: Change the first argument to PyImport_AppendInittab() to | |
| ``const char *`` as the string is stored beyond the call. | |
| - Some PyBytes_* aliases have been removed because they don't exist in 3.x. | |
| - Issue #5175: PyLong_AsUnsignedLongLong now raises OverflowError for negative | |
| arguments. Previously, it raised TypeError. | |
| - Issue #4720: The format for PyArg_ParseTupleAndKeywords can begin with '|'. | |
| - Issue #3632: From the gdb debugger, the 'pyo' macro can now be called when the | |
| GIL is released, or owned by another thread. | |
| - Issue #4122: On Windows, fix a compilation error when using the | |
| Py_UNICODE_ISSPACE macro in an extension module. | |
| - Issue #4293: Py_AddPendingCall() is now thread safe and can be used for | |
| asynchronous notifications to python from any thread. Documentation added. | |
| Extension Modules | |
| ----------------- | |
| - Issue #6508: Add posix.{getresuid,getresgid,setresuid,setresgid}. | |
| - Issue #7078: Set struct.__doc__ from _struct.__doc__. | |
| - Issue #3366: Add erf, erfc, expm1, gamma, lgamma functions to math module. | |
| - Issue #6823: Allow time.strftime() to accept a tuple with a isdst field | |
| outside of the range of [-1, 1] by normalizing the value to within that range. | |
| - Issue #6877: Make it possible to link the readline extension to libedit on | |
| OSX. | |
| - Issue #6944: Fix a SystemError when socket.getnameinfo() was called with | |
| something other than a tuple as first argument. | |
| - Issue #6865: Fix reference counting issue in the initialization of the pwd | |
| module. | |
| - Issue #6848: Fix curses module build failure on OS X 10.6. | |
| - Fix a segfault in expat when given a specially crafted input lead to the | |
| tokenizer not stopping. CVE-2009-3720. | |
| - Issue #6561: '\d' in a regex now matches only characters with Unicode category | |
| 'Nd' (Number, Decimal Digit). Previously it also matched characters with | |
| category 'No'. | |
| - Issue #1523: Remove deprecated overflow wrapping for struct.pack with an | |
| integer format code ('bBhHiIlLqQ'). Packing an out-of-range integer now | |
| consistently raises struct.error. | |
| - Issues #1530559, #1741130: Fix various struct.pack inconsistencies for the | |
| integer formats ('bBhHiIlLqQ'). In the following, '*' represents any of '=', | |
| '<', '>'. | |
| - Packing a float now always gives a Deprecation Warning. Previously it | |
| only warned for 'I', 'L', '*B', '*H', '*I', '*L'. | |
| - If x is not an int, long or float, then packing x will always result in | |
| struct.error. Previously an x with an __int__ method could be packed by | |
| 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a | |
| __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with | |
| neither __int__ nor __long__, TypeError used to be raised (with a | |
| confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and | |
| struct.error in other cases. | |
| Note: as of Python 2.7 beta 1, the above is out of date. In 2.7 beta 1, any | |
| argument with an __int__ method can be packed, but use of this feature | |
| triggers a DeprecationWarning. | |
| - Issue #4873: Fix resource leaks in error cases of pwd and grp. | |
| - Issue #4751: For hashlib algorithms provided by OpenSSL, the Python GIL is now | |
| released during computation on data lengths >= 2048 bytes. | |
| - Issue #3745: Fix hashlib to always reject unicode and non buffer-api | |
| supporting objects as input no matter how it was compiled (built in | |
| implementations or external openssl library). NOTE: Undone in 2.7a2. | |
| - Issue #4397: Fix occasional test_socket failure on OS X. | |
| - Issue #4279: Fix build of parsermodule under Cygwin. | |
| - Issue #4051: Prevent conflict of UNICODE macros in cPickle. | |
| - Issue #4228: Pack negative values the same way as 2.4 in struct's L format. | |
| - Issue #1040026: Fix os.times result on systems where HZ is incorrect. | |
| - Issues #3167, #3682: Fix test_math failures for log, log10 on Solaris, | |
| OpenBSD. | |
| - Issue #4365: Add crtassem.h constants to the msvcrt module. | |
| - Issue #4396: The parser module now correctly validates the with statement. | |
| - Issue #5228: Make functools.partial objects can now be pickled. | |
| Tests | |
| ----- | |
| - Issue #7431: Use TESTFN in test_linecache instead of trying to create a file | |
| in the Lib/test directory, which might be read-only for the user running the | |
| tests. | |
| - Issue #7324: Add a sanity check to regrtest argument parsing to catch the case | |
| of an option with no handler. | |
| - Issue #7312: Add a -F flag to run the selected tests in a loop until a test | |
| fails. Can be combined with -j. | |
| - Issue #7295: Do not use a hardcoded file name in test_tarfile. | |
| - Issue #7270: Add some dedicated unit tests for multi-thread synchronization | |
| primitives such as Lock, RLock, Condition, Event and Semaphore. | |
| - Issue #7222: Make thread "reaping" more reliable so that reference | |
| leak-chasing test runs give sensible results. The previous method of reaping | |
| threads could return successfully while some Thread objects were still | |
| referenced. This also introduces a new private function: ``thread._count()``. | |
| - Issue #7151: Fixed regrtest -j so that output to stderr from a test no longer | |
| runs the risk of causing the worker thread to fail. | |
| - Issue #7055: test___all__ now greedily detects all modules which have an | |
| __all__ attribute, rather than using a hardcoded and incomplete list. | |
| - Issue #7058: Added save/restore for things like sys.argv and cwd to | |
| runtest_inner in regrtest, with warnings if the called test modifies them, | |
| and a new section in the summary report at the end. | |
| - Issue #7042: Fix test_signal (test_itimer_virtual) failure on OS X 10.6. | |
| - Issue #6806: test_platform failed under OS X 10.6.0 because ``sw_ver`` leaves | |
| off the trailing 0 in the version number. | |
| - Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to | |
| Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate | |
| the same behaviour as test_ttkguionly (and now also test_tk) which is to skip | |
| the tests if DISPLAY is defined but can't be used. | |
| - Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running | |
| regression tests in parallel, shortening the total runtime. | |
| - Issue #5354: New test support function import_fresh_module() makes it easy to | |
| import both normal and optimised versions of modules. test_heapq and | |
| test_warnings have been adjusted to use it, tests for other modules with both | |
| C and Python implementations in the stdlib can be adjusted to use it over | |
| time. | |
| - Fix test_warnings to no longer reset the warnings filter. | |
| - Fix test_logging to no longer reset the warnings filter. | |
| - Issue #5635: Fix running test_sys with tracing enabled. | |
| - regrtest no longer treats ImportError as equivalent to SkipTest. Imports that | |
| should cause a test to be skipped are now done using import_module from test | |
| support, which does the conversion. | |
| - Issue #5083: New 'gui' resource for regrtest. | |
| - Issue #5837: Certain sequences of calls to set() and unset() for | |
| support.EnvironmentVarGuard objects restored the environment variables | |
| incorrectly on __exit__. | |
| - Issue #2389: Array objects are now pickled in a portable manner. | |
| Misc | |
| ---- | |
| - Issue #5611: Auto-detect whether a C file uses tabs or spaces in Vim. | |
| What's New in Python 2.6 final | |
| ============================== | |
| *Release date: 01-Oct-2008* | |

| objects, when the "start" parameter is a huge value. | |
| - Issue #3965: Fixed a crash on Windows when open() is given an invalid | |
| filename or mode, and the filename is a unicode string. | |
| - Bug #3951: Py_USING_MEMORY_DEBUGGER should not be enabled by default. | |
| Library | |
| ------- | |
| - Issue #3965: Allow repeated calls to turtle.Screen, by making it a | |
| true singleton object. | |
| - Issue #3895: It was possible to crash the interpreter when an external timer | |
| was used with cProfile that returned an object that could not be converted | |
| into a float. | |
| - Issue #3950: Made turtle respect scale factors. | |
| - Issue #3547: Fixed ctypes structures bitfields of varying integer | |
| sizes. | |
| - Issue #3879: A regression in urllib.getproxies_environment was fixed. | |
| - Issue #3863: Disabled a unit test of fork being called from a thread | |
| when running on platforms known to exhibit OS bugs when attempting that. | |
| Build | |
| ----- | |
| - Bug #3989: Package the 2to3 script (as 2to3.py) in the Windows | |
| installer. | |
| - Bug #3887: Package x64 version of CRT for AMD64 Windows binaries. | |
| What's New in Python 2.6 release candidate 2? | |
| ============================================= | |
| *Release date: 17-Sep-2008* | |
| Core and Builtins | |
| ----------------- | |
| Extension Modules | |
| ----------------- | |
| - Security Issue #2: imageop did not validate arguments correctly and could | |
| segfault as a result. | |
| - Issue #3886: Possible integer overflows in the _hashopenssl module were | |
| closed. | |
| Tools/Demos | |
| ----------- | |
| - Issue #3850: recursion tests in Tools/scripts/find_recursion_limit.py can raise | |
| AttributeError instead of RuntimeError, depending in which C API call | |
| exactly the recursion limit is exceeded. Consequently, both exception types | |
| are caught and silenced. | |
| Build | |
| ----- | |
| - Issue #3617: Include a licensing statement regarding the Microsoft | |
| C runtime in the Windows installer. | |
| What's New in Python 2.6 release candidate 1? | |
| ============================================= | |
| *Release date: 12-Sep-2008* | |
| Core and Builtins | |
| ----------------- | |
| - Issue #3642: Suppress warning in obmalloc when size_t is larger than uint. | |
| - Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with | |
| PyString_FromFormat or PyErr_Format to display size_t values. The macro | |
| PY_FORMAT_SIZE_T is designed to select the correct format for the OS | |
| ``printf`` function, whereas PyString_FromFormat has an independent | |
| implementation and uses "%zd" on all platforms for size_t values. | |
| This makes a difference on win64, where ``printf`` needs "%Id" to display | |
| 64bit values. | |
| - Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on | |
| error. | |
| - Issue #3777: long() applied to a float object now always return a long | |
| object; previously an int would be returned for small values. the __long__ | |
| method is allowed to return either an int or a long, but the behaviour of | |
| float objects should not change to respect backward compatibility. | |
| - Issue #3751: str.rpartition would perform a left-partition when called with | |
| a unicode argument. | |
| - Issue #3683: Fix compilation when --without-threads is given. | |
| - Issue #3668: Fix a memory leak with the "s*" argument parser in | |
| PyArg_ParseTuple and friends, which occurred when the argument for "s*" | |
| was correctly parsed but parsing of subsequent arguments failed. | |
| - Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to | |
| match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__ | |
| mechanism. In the process, fix a bug where isinstance() and issubclass(), | |
| when given a tuple of classes as second argument, were looking up | |
| __instancecheck__ / __subclasscheck__ on the tuple rather than on each | |
| type object. | |
| - Fix crashes on memory allocation failure found with failmalloc. | |
| - Fix memory leaks found with valgrind and update suppressions file. | |
| - Fix compiler warnings in opt mode which would lead to invalid memory reads. | |
| - Fix problem using wrong name in decimal module reported by pychecker. | |
| - Silenced another compiler warning about a used but not defined | |
| function 'stringlib_contains_obj'. | |
| - Added warnings on the use of ``__getslice__``, ``__setslice__``, or | |
| ``__delslice__``. | |
| - Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared | |
| library targets in the Makefile. | |
| - Issue #1204: The configure script now tests for additional libraries | |
| that may be required when linking against readline. This fixes issues | |
| with x86_64 builds on some platforms (a few Linux flavors and OpenBSD). | |
| C-API | |
| ----- | |
| - Aliased PyObject_Bytes to PyObject_Str. | |
| Library | |
| ------- | |
| - Issue #3640: Pickling a list or a dict uses less local variables, to reduce | |
| stack usage in the case of deeply nested objects. | |
| - Issue #3629: Fix sre "bytecode" validator for an end case. | |
| - Issue #3811: The Unicode database was updated to 5.1. | |
| - Issue #3781: Further warnings.catch_warnings() cleanup to prevent | |
| silent misbehaviour when a single instance is nested in multiple | |
| with statements, or when the methods are invoked in the wrong order. | |
| - Issue #3809: Fixed spurious 'test.blah' file left behind by test_logging. | |
| - Issue #3781: Clean up the API for warnings.catch_warnings() by having it | |
| return a list or None rather than a custom object. | |
| - Issue #1638033: Cookie.Morsel gained the httponly attribute. | |
| - Issue #3535: zipfile couldn't read some zip files larger than 2GB. | |
| - Issue #3776: Deprecate the bsddb package for removal in 3.0. | |
| - Issue #3762: platform.architecture() fails if python is lanched via | |
| its symbolic link. | |
| - Issue #3772: Fixed regression problem in StreamHandler.emit(). | |
| - Issue #600362: Relocated parse_qs() and parse_qsl(), from the cgi module | |
| to the urlparse one. Added a PendingDeprecationWarning in the old | |
| module, it will be deprecated in the future. | |
| - Issue #2562: Fix distutils PKG-INFO writing logic to allow having | |
| non-ascii characters and Unicode in setup.py meta-data. | |
| - Issue #3726: Allow spaces in separators in logging configuration files. | |
| - Issue #3719: platform.architecture() fails if there are spaces in the | |
| path to the Python binary. | |
| - Issue #3602: Moved test.test_support.catch_warning() to | |
| warnings.catch_warnings() along with some API cleanup. Expanding the tests | |
| for catch_warnings() also led to an improvement in the raising of a | |
| DeprecationWarning related to warnings.warn_explicit(). | |
| - The deprecation warnings for the old camelCase threading API were removed. | |
| - logging: fixed lack of use of encoding attribute specified on a stream. | |
| - Silenced a trivial compiler warning in the sqlite module. | |
| - Fixed two format strings in the _collections module. | |
| - Issue #3703: _fileio.FileIO gave unhelpful error message when trying to open a | |
| directory. | |
| - Issue #3708: os.urandom no longer goes into an infinite loop when passed a | |
| non-integer floating point number. | |
| - Issue #3110: multiprocessing fails to compiel on solaris 10 due to missing | |
| SEM_VALUE_MAX. | |
| Extension Modules | |
| ----------------- | |
| - Issue #4301: Patch the logging module to add processName support, remove | |
| _check_logger_class from multiprocessing. | |
| - Issue #2975: When compiling several extension modules with Visual Studio 2008 | |
| from the same python interpreter, some environment variables would grow | |
| without limit. | |
| - Issue #3643: Added a few more checks to _testcapi to prevent segfaults by | |
| exploitation of poor argument checking. | |
| - sqlite3: Changed docstring of iterdump() to mark method as "Non-standard". | |
| - Issue #3103: Reduced globals symbols used by sqlite3 module and made sure all | |
| remaining ones have "pysqlite_" prefix. | |
| - Issue #3846: Release the GIL during sqlite3_prepare calls. This improves | |
| concurrent access to the same SQLite database from multiple | |
| threads/processes. | |
| Tests | |
| ----- | |
| - Issue #3781: Add test.test_support.check_warnings() as a convenience | |
| wrapper for warnings.catch_warnings() that makes it easier to check | |
| that expected warning messages are being reported. | |
| - Issue #3796: Some tests functions were not enabled in test_float. | |
| - Issue #3768: Move test_py3kwarn over to the new API for catch_warnings(). | |
| Build | |
| ----- | |
| - Issue #3833: Use a different upgrade code for Win64 installers. | |
| - Issue #2271: Set SecureCustomProperties so that installation will properly | |
| use the TARGETDIR even for unprivileged users. | |
| - Allow passing the MSI file name to merge.py. | |
| - Issue #3758: Rename the 'check' target to 'patchcheck' so as to not clash | |
| with GNU build target guidelines. | |
| What's New in Python 2.6 beta 3? | |
| ================================ | |
| *Release date: 20-Aug-2008* | |
| Core and Builtins | |
| ----------------- | |
| - Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from | |
| Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party | |
| extensions do not automatically benefit from the class attribute | |
| cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG | |
| to their tp_flags field if they care. This is a backwards | |
| compatibility feature; in 3.0, all types will use the cache by | |
| default. | |
| - Keyword arguments can now follow starred arguments. (``f(a, *args, | |
| keyword=23)`` is now valid syntax.) | |
| - ctypes function pointers that are COM methods have a boolean True | |
| value again. | |
| - Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple, | |
| by denying s# to parse objects that have a releasebuffer procedure, | |
| and introducing s*. | |
| - Issue #3537: Fix an assertion failure when an empty but presized dict | |
| object was stored in the freelist. | |
| - Issue #1481296: Make long(float('nan')) and int(float('nan')) raise | |
| ValueError consistently across platforms. | |
| - Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long) | |
| (64bit Unix, for example), unichr() would truncate its argument and return | |
| u'\x00' for unichr(2**32). Now it properly raises an OverflowError. | |
| - Apply security patches from Apple. | |
| - Issue #2542: Now that issubclass() may call arbitrary code, ensure that | |
| PyErr_ExceptionMatches returns 0 when an exception occurs there. | |
| - Issue #1819: function calls with several named parameters are now on | |
| average 35% faster (as measured by pybench). | |
| - Issue #2378: An unexpected UnboundLocalError or NameError could appear when | |
| the python debugger steps into a class statement: the free variables (local | |
| variables defined in an outer scope) would be deleted from the outer scope. | |
| - Issue #2620: Overflow checking when allocating or reallocating memory | |
| was not always being done properly in some python types and extension | |
| modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have | |
| all been updated to perform better checks and places in the code that | |
| would previously leak memory on the error path when such an allocation | |
| failed have been fixed. | |
| Library | |
| ------- | |
| - Issue #3612: Added some missing basic types in ctypes.wintypes. | |
| - The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of | |
| symtable.Symbol have been deprecated for removal in 3.0 and the next release. | |
| - Issue #2234: distutils failed for some versions of the cygwin compiler. The | |
| version reported by these tools does not necessarily follow the python | |
| version numbering scheme, so the module is less strict when parsing it. | |
| - Issue #2235: Added Py3k warnings for types which will become unhashable | |
| under the stricter __hash__ inheritance rules in 3.0. Several types | |
| which did not meet the rules for hash invariants and were already | |
| unhashable in 3.0 have now been explicitly flagged as unhashable in | |
| 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite, | |
| xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList) | |
| - Update __all__ for cookielib, csv, os, urllib2, and weakref to include things | |
| imported into the module but exposed as part of the module's API. | |
| - Remove an unneeded import of abc.ABCMeta from 'inspect'. | |
| - Remove unneeded imports of 'sys' and 'warnings' from 'io'. | |
| - Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread. | |
| - Issue #3575: Incremental decoder's decode function now takes bytearray | |
| by using 's*' instead of 't#'. | |
| - Issue #2222: Fixed reference leak when occurred os.rename() | |
| fails unicode conversion on 2nd parameter. (windows only) | |
| - Issue #2464: urllib2 now supports a malformation in the URL received | |
| in a redirect. | |
| - Silence the DeprecationWarning raised when importing mimetools in | |
| BaseHTTPServer, cgi (and rfc822), httplib. | |
| - Issue #2776: fixed small issue when handling a URL with double slash | |
| after a 302 response in the case of not going through a proxy. | |
| - Issue #2676: in the email package, content-type parsing was hanging on | |
| pathological input because of quadratic or exponential behaviour of a | |
| regular expression. | |
| - Issue #3476: binary buffered reading through the new "io" library is now | |
| thread-safe. | |
| - Silence the DeprecationWarning of rfc822 when it is imported by mimetools | |
| since mimetools itself is deprecated. Because modules are cached, all | |
| subsequent imports of rfc822 will not raise a visible DeprecationWarning. | |
| - Issue #3134: shutil referenced undefined WindowsError symbol. | |
| - Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to | |
| menu entries were not deleted. | |
| - Copied the implementation of reduce() to _functools.reduce() to have a | |
| version that did not raise a DeprecationWarning under -3. | |
| - Issue #3205: When iterating over a BZ2File fails allocating memory, raise | |
| a MemoryError rather than silently stop the iteration. | |
| - Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode" | |
| to _sre.compile() will now be rejected. This should not affect anybody | |
| since the re.compile() function never generates invalid re-bytecode. | |
| - Issue #3436: Make csv.DictReader's fieldnames attribute a property so that | |
| upon first access it can be automatically initialized from the csv file if | |
| it wasn't initialized during instantiation. | |
| - Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as | |
| the reload() built-in has been removed. | |
| - Changed code in the following modules/packages to remove warnings raised | |
| while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb, | |
| ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email, | |
| filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile, | |
| pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket, | |
| subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap, | |
| threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib. | |
| - Issue #3039: Fix tarfile.TarFileCompat.writestr() which always | |
| raised an AttributeError. | |
| - Issue #2523: Fix quadratic behaviour when read()ing a binary file without | |
| asking for a specific length. This problem only affected files opened | |
| using the new "io" module, not the built-in open() function. | |
| - Issue #3449: Update decimal module to use most recent specification | |
| (v. 1.68) and tests (v. 2.58) from IBM. | |
| - Issue #3437: Bug fix in robotparser parsing of Allow: lines. | |
| - Issue #1592: Improve error reporting when operations are attempted | |
| on a closed shelf. | |
| - Deprecate the "ast" parser function aliases. | |
| - Issue #3120: On 64-bit Windows the subprocess module was truncating handles. | |
| - Issue #3303: Fix a crash in locale.strcoll() when calling it with | |
| invalid arguments. | |
| - Issue #3302: Fix several crashes when calling locale's gettext functions | |
| with None arguments. | |
| - Issue #3389: Allow resolving dotted names for handlers in logging | |
| configuration files. | |
| - Deprecate the sunaudio module for removal in Python 3.0. | |
| - Issue #3394: zipfile.writestr sets external attributes when passed a | |
| file name rather than a ZipInfo instance, so files are extracted with | |
| mode 0600 rather than 000 under Unix. | |
| - Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword | |
| argument in python 2.5, this broke code that subclassed Popen to include its | |
| own poll method. Fixed my moving _deadstate to an _internal_poll method. | |
| Build | |
| ----- | |
| - Generate the PatternGrammar pickle during "make install". | |
| Documentation | |
| ------------- | |
| - Issue #2235: the C API function PyObject_HashNotImplemented and its | |
| interaction with the tp_hash slot (added in 2.6b2) are now documented | |
| - Issue #643841: The language reference now provides more detailed | |
| coverage of the lookup process for special methods. The disclaimers | |
| regarding lack of coverage of new-style classes have also been | |
| removed, since the coverage is now fairly reasonable. | |
| What's New in Python 2.6 beta 2? | |
| ================================ | |
| *Release date: 17-Jul-2008* | |
| Core and Builtins | |
| ----------------- | |
| - Issue #3156: Fix inconsistent behavior of the bytearray type: all | |
| its methods now allow for items objects that can be converted to | |
| an integer using operator.index(). | |
| - Issue #3360: Fix incorrect parsing of '020000000000.0', which | |
| produced a ValueError instead of giving the correct float. | |
| - Issue #3083: Add alternate (#) formatting for bin, oct, hex output | |
| for str.format(). This adds the prefix 0b, 0o, or 0x, respectively. | |
| - Issue #3008: the float type has a new instance method 'float.hex' | |
| and a new class method 'float.fromhex' to convert floating-point | |
| numbers to and from hexadecimal strings, respectively. | |
| - Issue #2235: __hash__ is once again inherited by default. To allow | |
| collections.Hashable to remain meaningful in the presence of the | |
| default hash implementation (object.__hash__), it is now possible | |
| to explicit block inheritance of hash by setting __hash__=None at | |
| the Python level, or tp_hash=PyObject_HashNotImplemented at the C | |
| level. | |
| - Issue #3221: Issue a RuntimeWarning instead of raising SystemError if | |
| the parent module cannot be found while performing an absolute import. | |
| This means that an incorrectly defined __package__ attribute will | |
| now only prevent relative imports in that module rather than causing | |
| all imports from that module to fail. | |
| - Issue #2517: Allow unicode messages in Exceptions again by correctly | |
| bypassing the instance dictionary when looking up __unicode__ on | |
| new-style classes. | |
| - Issue #3242: Fix a crash inside the print statement, if sys.stdout is | |
| set to a custom object whose write() method happens to install | |
| another file in sys.stdout. | |
| - Issue #3088: Corrected a race condition in classes derived from | |
| threading.local: the first member set by a thread could be saved in | |
| another thread's dictionary. | |
| - Issue #3004: Minor change to slice.indices(): the start and stop | |
| arguments are now treated identically, making the behaviour easier | |
| to describe and understand. For example, slice(None, -10, | |
| 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and | |
| slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9, | |
| 10, -1). | |
| - Issue #3219: Calling a function with repeated keyword arguments, | |
| f(a=2, a=23), would not cause a syntax error. This was a regression | |
| from 2.4 caused by the switch to the new compiler. | |
| - Issue #2862: Make int and float freelist management consistent with | |
| other freelists. Changes their CompactFreeList apis into | |
| ClearFreeList apis and calls them via gc.collect(). | |
| Library | |
| ------- | |
| - Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python | |
| api functions without holding the GIL, which could lead to a fatal | |
| error when they failed. | |
| - Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects. | |
| - Issue #3395: fix reference in test_multiprocessing to old debugInfo method | |
| - Issue #3312: Fix two crashes in sqlite3. | |
| - Issue #1608818: Fix misbehavior in os.listdir() if readdir() fails. | |
| - Issue #3125: Remove copy_reg in multiprocessing and replace it with | |
| ForkingPickler.register() to resolve conflict with ctypes. | |
| - Issue #3090: Fixed ARCHFLAGS parsing on OS/X | |
| - Issue #3313: Fixed a crash when a failed dlopen() call does not set | |
| a valid dlerror() message. | |
| - Issue #3258: Fixed a crash when a ctypes POINTER type to an | |
| incomplete structure was created. | |
| - Issue #3339: dummy_thread.acquire() should not return None. | |
| - Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments. | |
| - Issue #3301: Bisect module behaved badly when lo was negative. | |
| - Issue #839496: SimpleHTTPServer used to open text files in text mode. This is | |
| both unnecessary (HTTP allows text content to be sent in several forms) and | |
| wrong because the actual transmitted size could differ from the | |
| content-length. The problem had been corrected in the 2.4 branch, but never | |
| merged into trunk. | |
| - Issue #2663: add filtering capability to shutil.copytree(). | |
| - Issue #1622: Correct interpretation of various ZIP header fields. | |
| - Issue #1526: Allow more than 64k files to be added to Zip64 file. | |
| - Issue #1746: Correct handling of zipfile archive comments (previously | |
| archives with comments over 4k were flagged as invalid). Allow writing | |
| Zip files with archives by setting the 'comment' attribute of a ZipFile. | |
| - Issue #449227: The rlcompleter module now adds "(" to callable objects | |
| when completed. | |
| - Issue #3190: Pydoc now hides the automatic module attribute __package__ (the | |
| handling is now the same as that of other special attributes like __name__). | |
| - Issue #2885 (partial): The urllib.urlopen() function has been deprecated for | |
| removal in Python 3.0 in favor of urllib2.urlopen(). | |
| - Issue #2113: Fix error in subprocess.Popen if the select system call is | |
| interrupted by a signal. | |
| - Issue #3309: Fix bz2.BZFile iterator to release its internal lock | |
| properly when raising an exception due to the bz2file being closed. | |
| Prevents a deadlock. | |
| - Issue #3094: httplib.HTTPSConnection Host: headers no longer include the | |
| redundant ":443" port number designation when the connection is using the | |
| default https port (443). | |
| - Issue #874900: after an os.fork() call the threading module state is cleaned | |
| up in the child process to prevent deadlock and report proper thread counts | |
| if the new process uses the threading module. | |
| Tests | |
| ----- | |
| - test.test_support.catch_warning now keeps track of all warnings it sees | |
| and is now better documented. Explicit unit tests for this context manager | |
| have been added to test_warnings. | |
| Build | |
| ----- | |
| - Issue #3215: Build sqlite3 as sqlite3.dll, not sqlite3.pyd. | |
| Documentation | |
| ------------- | |
| - Document that robotparser has been renamed to urllib.robotparser in | |
| Python 3.0. | |
| - Document that urlparse has been renamed to urllib.parse in Python 3.0. | |
| - Document that urllib2 is split across multiple modules and renamed in | |
| Python 3.0. | |
| - Document that urllib is split across multiple modules and renamed in | |
| Python 3.0. | |
| What's New in Python 2.6 beta 1? | |
| ================================ | |
| *Release date: 18-June-2008* | |
| Core and Builtins | |
| ----------------- | |
| - Issue #3211: warnings.warn_explicit() did not guard against its 'registry' | |
| argument being anything other than a dict or None. Also fixed a bug in error | |
| handling when 'message' and 'category' were both set to None, triggering a | |
| bus error. | |
| - Issue #3100: Corrected a crash on deallocation of a subclassed weakref which | |
| holds the last (strong) reference to its referent. | |
| - Add future_builtins.ascii(). | |
| - Several set methods now accept multiple arguments: update(), union(), | |
| intersection(), intersection_update(), difference(), and difference_update(). | |
| - Issue #2898: Added sys.getsizeof() to retrieve size of objects in bytes. | |
| - New environment variable PYTHONIOENCODING. | |
| - Patch #2488: Add sys.maxsize. | |
| - Issue #2353: file.xreadlines() now emits a Py3k warning. | |
| - Issue #2863: generators now have a ``gen.__name__`` attribute that | |
| equals ``gen.gi_code.co_name``, like ``func.__name___`` that equals | |
| ``func.func_code.co_name``. The repr() of a generator now also | |
| contains this name. | |
| - Issue #2831: enumerate() now has a ``start`` argument. | |
| - Issue #2801: fix bug in the float.is_integer method where a | |
| ValueError was sometimes incorrectly raised. | |
| - Issue #2790: sys.flags was not properly exposing its bytes_warning | |
| attribute. | |
| - Issue #2196: hasattr() now lets exceptions which do not inherit | |
| Exception (KeyboardInterrupt, and SystemExit) propagate instead of | |
| ignoring them. | |
| - Added checks for integer overflows, contributed by Google. Some are | |
| only available if asserts are left in the code, in cases where they | |
| can't be triggered from Python code. | |
| Extension Modules | |
| ----------------- | |
| - Issue #1179: [CVE-2007-4965] Integer overflow in imageop module. | |
| - Issue #3116: marshal.dumps() had quadratic behavior for strings > 32Mb. | |
| - Issue #2138: Add factorial() to the math module. | |
| - The heapq module does comparisons using LT instead of LE. This | |
| makes its implementation match that used by list.sort(). | |
| - Issue #2819: add full-precision summation function to math module, | |
| based on Hettinger's ASPN Python Cookbook recipe. | |
| - Issue #2592: delegate nb_index and the floor/truediv slots in | |
| weakref.proxy. | |
| - Support os.O_ASYNC and fcntl.FASYNC if the constants exist on the | |
| platform. | |
| - Support for Windows 9x has been removed from the winsound module. | |
| - bsddb module updated to version 4.7.3. | |
| http://www.jcea.es/programacion/pybsddb.htm#bsddb3-4.7.3. This | |
| code should be compatible with Python 3.0. | |
| - Issue #2858: Fix potential memory corruption when | |
| bsddb.db.DBEnv.lock_get and other bsddb.db object constructors | |
| raised an exception. | |
| - Issue #2669: bsddb/__init__.py iteration no longer silently fails when | |
| the database has changed size during iteration. It now raises a | |
| RuntimeError in the same manner as a dictionary. | |
| - Issue #2870: cmathmodule.c compile error. | |
| - Added a threading.Thread.ident property. | |
| Library | |
| ------- | |
| - logging.config: Removed out-of-date comment in _install_handlers and | |
| used issubclass in place of equality comparison of classes. | |
| - Issue #2722: Now the os.getcwd() supports very long path names. | |
| - Issue #2888: Fixed the behaviour of pprint when working with nested | |
| structures, to match the behaviour of 2.5 and 3.0 (now follows the common | |
| sense). | |
| - Issue #1817: cgi now correctly handles the querystring on POST requests | |
| - Issue #3136: fileConfig()'s disabling of old loggers is now conditional via | |
| an optional disable_existing_loggers parameter, but the default value is | |
| such that the old behaviour is preserved. Thanks to Leandro Lucarella for | |
| the patch. | |
| - Issue #3126: StreamHandler and FileHandler check before calling "flush" and | |
| "close" that the stream object has these, using hasattr (thanks to bobf for | |
| the patch). | |
| - Issue #2912: platform.uname now tries to determine unknown information even if | |
| os.uname exists. | |
| - The rfc822 module has been deprecated for removal in 3.0. | |
| - The mimetools module has been deprecated for removal in 3.0. | |
| - The ctypes.byref function now takes an optional second parameter | |
| which specifies an offset in bytes for the constructed pointer-like object. | |
| - Added the ast module. | |
| - Added the multiprocessing module, PEP 371. | |
| - Factored out the indentation cleaning from inspect.getdoc() into | |
| inspect.cleandoc() to ease standalone use. | |
| - Issue #1798: Add ctypes calling convention that allows safe access | |
| to errno. | |
| - Issue #2404: ctypes objects support the new pep3118 buffer interface. | |
| - Patch #2125: Add GetInteger and GetString methods for | |
| msilib.Record objects. | |
| - Issue #2782: The datetime module's strftime methods now accept | |
| unicode format strings just as time.strftime always has. | |
| - The sgmllib and htmllib modules have been deprecated for removal | |
| in Python 3.0. | |
| - Issue #3011: locale module alias table was updated to the latest | |
| version from the X.org locale.alias file. | |
| - Issue #1797 (partial fix): ctypes NULL function pointers have a | |
| False boolean value now. | |
| - Issue #2985: Allow 64-bit integer responses (``<i8>``) in XMLRPC | |
| transfers. | |
| - Issue #2877: The UserString.MutableString class has been removed in | |
| Python 3.0. | |
| - Do not close external file objects passed to tarfile.open(mode='w:bz2') | |
| when the TarFile is closed. | |
| - Issue #2959: For consistency with other file-like objects, gzip's | |
| GzipFile.close() can now be called multiple times without raising | |
| an exception. | |
| - Issue #1390: Raise ValueError in toxml when an invalid comment would | |
| otherwise be produced. | |
| - Issue #2914: TimedRotatingFileHandler now takes an optional keyword | |
| argument "utc" to use UTC time rather than local time. | |
| - Issue #2929: TimedRotatingFileHandler was using the wrong path when | |
| deleting old log files (filename only instead of full path). | |
| - Issue #1775025: You can now specify zipfile members to open(), | |
| read() or extract() via a ZipInfo instance. This allows handling | |
| duplicate filenames in zipfiles. | |
| - Issue #961805: Fix Text.edit_modified() in Tkinter. | |
| - Issue #1793: Function ctypes.util.find_msvcrt() added that returns | |
| the name of the C runtime library that Python uses. | |
| ctypes.util.find_library(name) now call this function when name is | |
| 'm' or 'c'. | |

| - The PyString functions have been renamed to PyBytes. A batch of | |
| defines were added so that the linker still sees the original | |
| PyString names. | |
| What's New in Python 2.6 alpha 3? | |
| ================================= | |
| *Release date: 08-May-2008* | |
| Core and builtins | |
| ----------------- | |
| - Issue #2719: backported the ``next()`` builtin from Python 3. | |
| - Issue #2681: The octal literal ``0o8`` was incorrecly acctepted. Now | |
| it properly raises a SyntaxError. | |
| - Issue #2617: Reserved -J and -X arguments for Jython, IronPython and | |
| other implementations of Python. | |
| - Implemented PEP 370: Per user site-packages directory. | |
| Extension Modules | |
| ----------------- | |
| - Issue #2670: Fix a failure in urllib2.build_opener(), when passed | |
| two handlers that derive the same default base class. | |
| - Added kill, terminate and send_signal(sig) to subprocess.Popen. | |
| - Added phase(z) -> phi, polar(z) -> r, phi and rect(r, phi) -> z to | |
| the cmath module. | |
| - Four new methods were added to the math and cmath modules: acosh, | |
| asinh, atanh and log1p. | |
| - zlib.decompressobj().flush(value) no longer crashes the interpreter | |
| when passed a value less than or equal to zero. | |
| - Issue #1631171: Re-implement the 'warnings' module in C (the | |
| original Python code has been kept as backup). This will allow for | |
| using the 'warning's machinery in such places as the parser where | |
| use of pure Python code is not possible. Both the ``showarning()`` | |
| and ``formatwarning()`` gain an optional 'line' argument which is | |
| not called by default for backwards-compatibility reasons. Setting | |
| ``warnings.showwarning()`` to an implementation that lacks support | |
| for the ``line`` argument will raise a DeprecationWarning. | |
| Library | |
| ------- | |
| - The audiodev module has been deprecated for removal in Python 3.0. | |
| - Issue #2750: Add the 'json' package. Based on simplejson 1.9 and | |
| contributed by Bob Ippolito. | |
| - Issue #1734346: Support Unicode file names for zipfiles. | |
| - Issue #2581: distutils: Vista UAC/elevation support for | |
| bdist_wininst. | |
| - Issue #2635: Fix bug in 'fix_sentence_endings' textwrap.fill option, | |
| where an extra space was added after a word containing (but not | |
| ending in) '.', '!' or '?'. | |
| - Add from_buffer() and from_buffer_copy() class methods to ctypes | |
| data types. | |
| - Issue #2682: ctypes callback functions no longer contain a cyclic | |
| reference to themselves. | |
| - The getpass module has been improved on Unix. It now uses /dev/tty | |
| by default and uses stderr instead of stdout. A GetPassWarning is | |
| issued when input echo cannot be controlled. | |
| - Issue #2014: Allow XML-RPC datetime objects to have dates before | |
| 1900-01-01. | |
| - Issue #2439: Added new function pkgutil.get_data(), which is a | |
| convenience wrapper for the PEP 302 get_data() API. | |
| - Issue #2616: The ctypes.pointer() and ctypes.POINTER() functions are | |
| now implemented in C for better performance. | |
| - Issue #2408: The ``_types`` module, which was used as in | |
| implementation detail of the public ``types`` module, has been | |
| removed and replaced by pure python code. | |
| - Issue #2513: distutils on Windows is now capable of cross-compiling | |
| extension modules between 32 and 64 bit platforms. See the distutls | |
| build documentation for more information. | |
| - Issue #815646: Individual file objects may now be used from multiple | |
| threads at once without fear of crashing the Python interpreter. If | |
| file.close() is called while an object is in use by another thread | |
| an IOError exception will be raised and the file will not be closed. | |
| - The bundled libffi copy is now in sync with the recently released | |
| libffi3.0.5 version, apart from some small changes to | |
| Modules/_ctypes/libffi/configure.ac. | |
| - Issue #2385: distutils.core.run_script() makes __file__ available, | |
| so the controlled environment will more closely mirror the typical | |
| script environment. This supports setup.py scripts that refer to | |
| data files. | |
| Tests | |
| ----- | |
| - Issue #2550: The approach used by client/server code for obtaining | |
| ports to listen on in network-oriented tests has been refined in an | |
| effort to facilitate running multiple instances of the entire | |
| regression test suite in parallel without issue. | |
| test_support.bind_port() has been fixed such that it will always | |
| return a unique port -- which wasn't always the case with the | |
| previous implementation, especially if socket options had been set | |
| that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The | |
| new implementation of bind_port() will actually raise an exception | |
| if it is passed an AF_INET/SOCK_STREAM socket with either the | |
| SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if | |
| available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on | |
| the socket it's been passed. This currently only applies to | |
| Windows. This option prevents any other sockets from binding to the | |
| host/port we've bound to, thus removing the possibility of the | |
| 'non-deterministic' behaviour, as Microsoft puts it, that occurs | |
| when a second SOCK_STREAM socket binds and accepts to a host/port | |
| that's already been bound by another socket. The optional preferred | |
| port parameter to bind_port() has been removed. Under no | |
| circumstances should tests be hard coding ports! | |
| test_support.find_unused_port() has also been introduced, which will | |
| pass a temporary socket object to bind_port() in order to obtain an | |
| unused port. The temporary socket object is then closed and | |
| deleted, and the port is returned. This method should only be used | |
| for obtaining an unused port in order to pass to an external program | |
| (i.e. the -accept [port] argument to openssl's s_server mode) or as | |
| a parameter to a server-oriented class that doesn't give you direct | |
| access to the underlying socket used. | |
| Finally, test_support.HOST has been introduced, which should be used | |
| for the host argument of any relevant socket calls (i.e. bind and | |
| connect). | |
| The following tests were updated to following the new conventions: | |
| test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib, | |
| test_poplib, test_ftplib, test_telnetlib, test_socketserver, | |
| test_asynchat and test_socket_ssl. | |
| It is now possible for multiple instances of the regression test | |
| suite to run in parallel without issue. | |
| Build | |
| ----- | |
| - Issue #1496032: On alpha, use -mieee when gcc is the compiler. | |
| - Issue #2544: On HP-UX systems, use 'gcc -shared' for linking when | |
| gcc is used as compiler. | |
| - Issue #2573: On MacOS X it is now possible to install the framework | |
| with a different name using --with-framework-name=NAME. | |
| C API | |
| ----- | |
| - Added implementation of copysign, acosh, asinh, atanh and log1p to | |
| the new files Include/pymath.h and Python/pymath.h for platforms | |
| which provide the functions through their libm. The files also | |
| contains several helpers and constants for math. | |
| - Added a new convenience macro, PyErr_WarnPy3k, for issuing Py3k warnings. | |
| What's New in Python 2.6 alpha 2? | |
| ================================= | |
| *Release date: 02-Apr-2008* | |
| Core and builtins | |
| ----------------- | |
| - Issue #1733757: The interpreter would hang on shutdown if the | |
| tracing function set by sys.settrace is still active and happens to | |
| call threading.currentThread(). | |
| - Patch #1442: properly report exceptions when the PYTHONSTARTUP file | |
| cannot be executed. | |
| - The compilation of a class nested in another class used to leak one | |
| reference on the outer class name. | |
| - Patch #1810: compile() can now compile _ast trees as returned by | |
| ``compile(..., PyCF_ONLY_AST)``. | |
| - Patch #2426: Added sqlite3.Connection.iterdump method to allow easy | |
| dumping of databases. Contributed by Paul Kippes at PyCon 2008. | |
| - Patch #2477: Added from __future__ import unicode_literals. | |
| - Added backport of bytearray type. | |
| - Issue #2355: add Py3k warning for buffer(). | |
| - Issue #1477: With narrow Unicode builds, the unicode escape sequence | |
| \Uxxxxxxxx did not accept values outside the Basic Multilingual | |
| Plane. This affected raw unicode literals and the | |
| 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in | |
| this case, like normal unicode literals and the 'unicode-escape' | |
| codec. | |
| - Issue #2348: add Py3k warning for file.softspace. | |
| - Issue #2346/#2347: add Py3k warnings for __methods__ and | |
| __members__. | |
| - Issue #2358: Add a Py3k warning on sys.exc_clear() usage. | |
| - Issue #2400: Allow relative imports to "import *". | |
| - Issue #1745: Backport print function with ``from __future__ import | |
| print_function``. | |

| The two changes are: im_self -> __self__ and im_func -> __func__ | |
| - Issue #2379: Raise a Py3K warning for __getitem__ or __getslice__ on | |
| exception instances. | |
| - Issue #2371: Add a Py3k warning when catching an exception that | |
| doesn't derive from BaseException. | |
| - Issue #2341: Add a Py3k warning when raising an exception that | |
| doesn't derive from BaseException. | |
| - Issue #2321: use pymalloc for unicode object string data to reduce | |
| memory usage in some circumstances. | |
| - PEP 3127: octal literals now start with "0o". Old-style octal | |
| literals are still valid. There are binary literals with a prefix of | |
| "0b". This also affects int(x, 0). | |
| - Issue #2359: Adding deprecation warnings for array.{read,write}. | |
| - Issue #1779871: GNU gcc can now build Python on OS X because the | |
| flags -Wno-long-double, -no-cpp-precomp, and -mno-fused-madd are no | |
| longer passed. | |
| - Add a warning when asserting a non-empty tuple which is always true. | |
| - Issue #2179: speed up with statement execution by storing the exit | |
| method on the stack instead of in a temporary variable (patch by | |
| Jeffrey Yaskin) | |
| - Issue #2238: Some syntax errors in *args and **kwargs expressions | |
| could give bogus error messages. | |
| - Issue #2143: Fix embedded readline() hang on SSL socket EOF. | |
| Extension Modules | |
| ----------------- | |
| - Patch #2240: Implement signal.setitimer and signal.getitimer. | |
| Library | |
| ------- | |
| - Issue #2315: logging.handlers: TimedRotatingFileHandler now accounts | |
| for daylight savings time in calculating the next rollover. | |
| - Issue #2316: logging.handlers: TimedRotatingFileHandler now | |
| calculates rollovers correctly even when nothing is logged for a | |
| while. | |
| - Issue #2317: logging.handlers: TimedRotatingFileHandler now uses | |
| improved logic for removing old files. | |
| - Issue #2495: tokenize.untokenize now inserts a space between two | |
| consecutive string literals; previously, ["" ""] was rendered as | |
| [""""], which is incorrect python code. | |
| - Issue #2248: return the result of the QUIT command. from | |
| SMTP.quit(). | |
| - Backport of Python 3.0's io module. | |
| - Issue #2482: Make sure that the coefficient of a Decimal is always | |
| stored as a str instance, not as a unicode instance. This ensures | |
| that str(Decimal) is always an instance of str. | |
| - Issue #2478: fix failure of decimal.Decimal(0).sqrt() | |
| - Issue #2432: give DictReader the dialect and line_num attributes | |
| advertised in the docs. | |
| - Issue #2460: Make Ellipsis object copyable. | |
| - Issue #1681432: Add triangular distribution to the random module | |
| - Issue #2136: urllib2's auth handler now allows single-quoted realms | |
| in the WWW-Authenticate header. | |
| - Issue #2434: Enhanced platform.win32_ver() to also work on Python | |
| installation which do not have the win32all package installed. | |
| - Added support to platform.uname() to also report the machine and | |
| processor information on Windows XP and later. As a result, | |
| platform.machine() and platform.processor() will report this | |
| information as well. | |
| - The library implementing the 2to3 conversion, lib2to3, was added to | |
| the standard distribution. | |
| - Issue #1747858: Fix chown to work with large uid's and gid's on | |
| 64-bit platforms. | |
| - Issue #1202: zlib.crc32 and zlib.adler32 no longer return different | |
| values on 32-bit vs. 64-bit python interpreters. Both were correct, | |
| but they now both return a signed integer object for consistency. | |
| - Issue #1158: add %f format (fractions of a second represented as | |
| microseconds) to datetime objects. Understood by both strptime and | |
| strftime. | |
| - Issue #705836: struct.pack(">f", x) now raises OverflowError on all | |
| platforms when x is too large to fit into an IEEE 754 float; | |
| previously it only raised OverflowError on non IEEE 754 platforms. | |
| - Issues #2166, #1741 and #1531505: now distutils deals with HOME | |
| correctly under win32 | |
| - Patch #1858: distutils: added multiple server support in .pypirc | |
| - Issue #1106316: pdb.post_mortem()'s parameter, "traceback", is now | |
| optional: it defaults to the traceback of the exception that is | |
| currently being handled (is mandatory to be in the middle of an | |
| exception, otherwise it raises ValueError). | |
| - Issue #1193577: A .shutdown() method has been added to SocketServers | |
| which terminates the .serve_forever() loop. | |
| - Issue #2220: handle rlcompleter attribute match failure more | |
| gracefully. | |
| - Issue #2225: py_compile, when executed as a script, now returns a | |
| non- zero status code if not all files could be compiled | |
| successfully. | |
| - Bug #1725737: In distutils' sdist, exclude RCS, CVS etc. also in the | |
| root directory, and also exclude .hg, .git, .bzr, and _darcs. | |
| - Issue #1872: The struct module typecode for _Bool has been changed | |
| from 't' to '?'. | |
| - The bundled libffi copy is now in sync with the recently released | |
| libffi3.0.4 version, apart from some small changes to | |
| Modules/_ctypes/libffi/configure.ac. On OS X, preconfigured libffi | |
| files are used. On all linux systems the --with-system-ffi | |
| configure option defaults to "yes". | |
| - Issue #1577: shutil.move() now calls os.rename() if the destination | |
| is a directory instead of copying-then-remove-source. | |
| Tests | |
| ----- | |
| - test_nis no longer fails when test.test_support.verbose is true and | |
| NIS is not set up on the testing machine. | |
| - Output comparison tests are no longer supported. | |
| - Rewrite test_errno to use unittest and no longer be a no-op. | |
| - GHOP 234: Convert test_extcall to doctest. | |
| - GHOP 290: Convert test_dbm and test_dummy_threading to unittest. | |
| - GHOP 293: Convert test_strftime, test_getargs, and test_pep247 to | |
| unittest. | |
| - Issue #2055: Convert test_fcntl to unittest. | |
| - Issue #1960: Convert test_gdbm to unittest. | |
| - GHOP 294: Convert test_contains, test_crypt, and test_select to | |
| unittest. | |
| - GHOP 238: Convert test_tokenize to use doctest. | |
| - GHOP 237: Rewrite test_thread using unittest. | |
| - Patch #2232: os.tmpfile might fail on Windows if the user has no | |
| permission to create files in the root directory. | |
| Build | |
| ----- | |
| - A new script 2to3 is now installed, to run the 2.x to 3.x converter. | |
| - Python/memmove.c and Python/strerror.c have been removed; both | |
| functions are in the C89 standard library. | |
| - Patch #2284: Add -x64 option to rt.bat. | |
| C API | |
| ----- | |
| - Patch #2477: Added PyParser_ParseFileFlagsEx() and | |
| PyParser_ParseStringFlagsFilenameEx(). | |
| What's New in Python 2.6 alpha 1? | |
| ================================= | |
| *Release date: 29-Feb-2008* | |
| Core and builtins | |
| ----------------- | |
| - Issue #2051: pyc and pyo files are no longer created with permission | |
| 644. The mode is now inherited from the py file. | |
| - Issue #2067: file.__exit__() now calls subclasses' close() method. | |
| - Patch #1759: Backport of PEP 3129 class decorators. | |
| - Issue #1881: An internal parser limit has been increased. Also see | |
| issue #215555 for a discussion. | |
| - Added the future_builtins module, which contains hex() and oct(). | |
| These are the PEP 3127 version of these functions, designed to be | |
| compatible with the hex() and oct() builtins from Python 3.0. They | |
| differ slightly in their output formats from the existing, unchanged | |
| Python 2.6 builtins. The expected usage of the future_builtins | |
| module is: | |
| from future_builtins import hex, oct | |
| - Issue #1600: Modified PyOS_ascii_formatd to use at most 2 digit | |
| exponents for exponents with absolute value < 100. Follows C99 | |
| standard. This is a change on Windows, which would use 3 digits. | |
| Also, added 'n' to the formats that PyOS_ascii_formatd understands, | |
| so that any alterations it does to the resulting string will be | |
| available in stringlib/formatter.h (for float.__format__). | |
| - Implemented PEP 3101, Advanced String Formatting. This adds a new | |
| builtin format(); a format() method for str and unicode; a | |
| __format__() method to object, str, unicode, int, long, float, and | |
| datetime; the class string.Formatter; and the C API | |
| PyObject_Format(). | |
| - Fixed several potential crashes, all caused by specially crafted | |
| __del__ methods exploiting objects in temporarily inconsistent | |
| state. | |
| - Issue #2115: Important speedup in setting __slot__ attributes. Also | |
| prevent a possible crash: an Abstract Base Class would try to access | |
| a slot on a registered virtual subclass. | |
| - Fixed repr() and str() of complex numbers with infinity or nan as | |
| real or imaginary part. | |
| - Clear all free lists during a gc.collect() of the highest generation | |
| in order to allow pymalloc to free more arenas. Python may give back | |
| memory to the OS earlier. | |
| - Issue #2045: Fix an infinite recursion triggered when printing a | |
| subclass of collections.defaultdict, if its default_factory is set | |
| to a bound method. | |
| - Fixed a minor memory leak in dictobject.c. The content of the free | |
| list was not freed on interpreter shutdown. | |
| - Limit free list of method and built-in function objects to 256 | |
| entries each. | |
| - Patch #1953: Added ``sys._compact_freelists()`` and the C API | |
| functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList`` | |
| to compact the internal free lists of pre-allocted ints and floats. | |
| - Issue #1983: Fixed return type of fork(), fork1() and forkpty() | |
| calls. Python expected the return type int but the fork familie | |
| returns pi_t. | |
| - Issue #1678380: Fix a bug that identifies 0j and -0j when they | |
| appear in the same code unit. | |
| - Issue #2025: Add tuple.count() and tuple.index() methods to comply | |
| with the collections.Sequence API. | |
| - Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and | |
| linebreak detection | |
| - Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear | |
| the internal lookup cache for ref leak tests. | |
| - Patch #1473257: generator objects gain a gi_code attribute. This is | |
| the same object as the func_code attribute of the function that | |
| produced the generator. | |
| - Issue #1920: "while 0" statements were completely removed by the | |
| compiler, even in the presence of an "else" clause, which is | |
| supposed to be run when the condition is false. Now the compiler | |
| correctly emits bytecode for the "else" suite. | |
| - A few crashers fixed: weakref_in_del.py (issue #1377858); | |
| loosing_dict_ref.py (issue #1303614, test67.py); | |
| borrowed_ref_[34].py (not in tracker). | |
| - Issue #1069410: The "can't load dll" message box on Windows is | |
| suppressed while an extension is loaded by calling SetErrorMode in | |
| dynload_win.c. The error is still reported properly. | |
| - Issue #1915: Python compiles with --enable-unicode=no again. However | |
| several extension methods and modules do not work without unicode | |
| support. | |
| - Issue #1882: when compiling code from a string, encoding cookies in the | |
| second line of code were not always recognized correctly. | |
| - Issue #1679: "0x" was taken as a valid integer literal. | |
| - Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were | |
| added. | |
| - sys.float_info / PyFloat_GetInfo: The floating point information | |
| object was converted from a dict to a specialized structseq object. | |
| - Patch #1816: Added sys.flags structseq. It exposes the status of | |
| most command line arguments and PYTHON* environment variables. | |
| - Objects/structseq.c: Implemented new structseq representation. The | |
| patch makes structseqs (e.g. the return value of os.stat) more | |
| readable. | |
| - Patch #1700288: added a type attribute cache that caches method | |
| accesses, resulting in speedups in heavily object-oriented code. | |
| - Bug #1776: __import__() no longer accepts filenames on any platform. | |
| The first parameter to __import__() must be a valid module name. | |
| - Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG. | |
| - Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE | |
| envvar and sys.dont_write_bytecode attribute. All these can be set | |
| to forbid Python to attempt to write compiled bytecode files. | |
| - Improve some exception messages when Windows fails to load an | |
| extension module. Now we get for example '%1 is not a valid Win32 | |
| application' instead of 'error code 193'. | |
| - Bug #1481296: Fixed long(float('nan')) != 0L. | |
| - Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x, | |
| y) functions. | |
| - Issue #1635: Platform independent creation and representation of NaN | |
| and INF. float("nan"), float("inf") and float("-inf") now work on | |
| every platform with IEEE 754 semantics. | |
| - Compiler now generates simpler and faster code for dictionary | |
| literals. The oparg for BUILD_MAP now indicates an estimated | |
| dictionary size. There is a new opcode, STORE_MAP, for adding | |
| entries to the dictionary. | |
| - Issue #1638: %zd configure test fails on Linux. | |
| - Issue #1620: New property decorator syntax was modifying the | |
| decorator in place instead of creating a new decorator object. | |
| - Issue #1538: Avoid copying string in split/rsplit if the split char | |
| is not found. | |
| - Issue #1553: An erroneous __length_hint__ can make list() raise a | |
| SystemError. | |
| - PEP 366: Allow explicit relative imports when executing modules | |
| inside packages with the -m switch via a new module level | |
| __package__ attribute. | |
| - Issue #1402: Fix a crash on exit, when another thread is still | |
| running, and if the deallocation of its frames somehow calls the | |
| PyGILState_Ensure() / PyGILState_Release() functions. | |
| - Expose the Py_Py3kWarningFlag as sys.py3kwarning. | |
| - Issue #1445: Fix a SystemError when accessing the ``cell_contents`` | |
| attribute of an empty cell object. | |
| - Issue #1460: The utf-7 incremental decoder did not accept truncated | |
| input. It now correctly saves its state between chunks of data. | |
| - Patch #1739468: Directories and zipfiles containing a __main__.py | |
| file can now be directly executed by passing their name to the | |
| interpreter. The directory/zipfile is automatically inserted as the | |
| first entry in sys.path. | |
| - Issue #1265: Fix a problem with sys.settrace, if the tracing | |
| function uses a generator expression when at the same time the | |
| executed code is closing a paused generator. | |
| - sets and frozensets now have an isdisjoint() method. | |
| - optimize the performance of builtin.sum(). | |
| - Fix warnings found by the new version of the Coverity checker. | |
| - The enumerate() built-in function is no longer bounded to sequences | |
| smaller than LONG_MAX. Formerly, it raised an OverflowError. Now, | |
| automatically shifts from ints to longs. | |
| - Issue #1686386: Tuple's tp_repr did not take into account the | |
| possibility of having a self-referential tuple, which is possible | |
| from C code. Nor did object's tp_str consider that a type's tp_str | |
| could do something that could lead to an inifinite recursion. | |
| Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the | |
| issues. | |
| - Issue #1164: It was possible to trigger deadlock when using the | |
| 'print' statement to write to a file since the GIL was not released | |
| as needed. Now PyObject_Print() does the right thing along with | |
| various tp_print implementations of the built-in types and those in | |
| the collections module. | |
| - Issue #1147: Exceptions were directly allowing string exceptions in | |
| their throw() method even though string exceptions no longer | |
| allowed. | |
| - Issue #1096: Prevent a segfault from getting the repr of a very | |
| deeply nested list by using the recursion counter. | |
| - Issue #1202533: Fix infinite recursion calls triggered by calls to | |
| PyObject_Call() never calling back out to Python code to trigger | |
| recursion depth updates/checks. Required the creation of a static | |
| RuntimeError instance in case normalizing an exception put the | |
| recursion check value past its limit. Fixes crashers | |
| infinite_rec_(1|2|4|5).py. | |
| - Patch #1031213: Decode source line in SyntaxErrors back to its | |
| original source encoding. | |
| - Patch #1673759: add a missing overflow check when formatting floats | |
| with %G. | |
| - Prevent expandtabs() on string and unicode objects from causing a | |
| segfault when a large width is passed on 32-bit platforms. | |
| - Issue #1733488: Fix compilation of bufferobject.c on AIX. | |
| - Issue #1722485: remove docstrings again when running with -OO. | |
| - Add new attribute names for function objects. All the func_* become | |
| __*__ attributes. (Some already existed, e.g., __doc__ and | |
| __name__.) | |
| - Add -3 option to the interpreter to warn about features that are | |
| deprecated and will be changed/removed in Python 3.0. | |
| - Patch #1686487: you can now pass any mapping after '**' in function | |
| calls. | |
| - except clauses may now be spelled either "except E, target:" or | |
| "except E as target:". This is to provide forwards compatibility | |
| with Python 3.0. | |
| - Deprecate BaseException.message as per PEP 352. | |
| - Issue #1303614: don't expose object's __dict__ when the dict is | |
| inherited from a built-in base. | |
| - When __slots__ are set to a unicode string, make it work the same as | |
| setting a plain string, ie don't expand to single letter identifiers. | |
| - Request #1191699: Slices can now be pickled. | |
| - Request #1193128: str.translate() now allows a None argument for | |
| translations that only remove characters without re-mapping the | |
| remaining characters. | |
| - Patch #1682205: a TypeError while unpacking an iterable is no longer | |
| masked by a generic one with the message "unpack non-sequence". | |
| - Remove unused file Python/fmod.c. | |
| - Bug #1683368: The object.__init__() and object.__new__() methods are | |
| now stricter in rejecting excess arguments. The only time when | |
| either allows excess arguments is when it is not overridden and the | |
| other one is. For backwards compatibility, when both are | |
| overridden, it is a deprecation warning (for now; maybe a Py3k | |
| warning later). Also, type.__init__() insists on the same signature | |
| as supported by type.__new__(). | |
| - Patch #1675423: PyComplex_AsCComplex() now tries to convert an | |
| object to complex using its __complex__() method before falling back | |
| to the __float__() method. Therefore, the functions in the cmath | |
| module now can operate on objects that define a __complex__() | |
| method. | |
| - Patch #1623563: allow __class__ assignment for classes with | |
| __slots__. The old and the new class are still required to have the | |
| same slot names. | |
| - Patch #1642547: Fix an error/crash when encountering syntax errors | |
| in complex if statements. | |
| - Patch #1462488: Python no longer segfaults when | |
| ``object.__reduce_ex__()`` is called with an object that is faking | |
| its type. | |
| - Patch #1680015: Don't modify __slots__ tuple if it contains a | |
| unicode name. | |
| - Patch #1444529: the builtin compile() now accepts keyword arguments. | |
| - Bug #1678647: write a newline after printing an exception in any | |
| case, even when converting the value to a string failed. | |
| - The dir() function has been extended to call the __dir__() method on | |
| its argument, if it exists. If not, it will work like before. This | |
| allows customizing the output of dir() in the presence of a | |
| __getattr__(). | |
| - Patch #922167: Python no longer segfaults when faced with infinitely | |
| self-recursive reload() calls (as reported by bug #742342). | |
| - Patch #1675981: remove unreachable code from ``type.__new__()`` | |
| method. | |
| - Patch #1491866: change the complex() constructor to allow | |
| parthensized forms. This means complex(repr(x)) now works instead of | |
| raising a ValueError. | |
| - Patch #703779: unset __file__ in __main__ after running a file. This | |
| makes the filenames the warning module prints much more sensible | |
| when a PYTHONSTARTUP file is used. | |
| - Variant of patch #697613: don't exit the interpreter on a SystemExit | |
| exception if the -i command line option or PYTHONINSPECT environment | |
| variable is given, but break into the interactive interpreter just | |
| like on other exceptions or normal program exit. | |
| - Patch #1638879: don't accept strings with embedded NUL bytes in | |
| long(). | |
| - Bug #1674503: close the file opened by execfile() in an error | |
| condition. | |
| - Patch #1674228: when assigning a slice (old-style), check for the | |
| sq_ass_slice instead of the sq_slice slot. | |
| - When printing an unraisable error, don't print exceptions. before | |
| the name. This duplicates the behavior whening normally printing | |
| exceptions. | |
| - Bug #1653736: Properly discard third argument to | |
| slot_nb_inplace_power. | |
| - PEP 352: Raising a string exception now triggers a TypeError. | |
| Attempting to catch a string exception raises DeprecationWarning. | |
| - Bug #1377858: Fix the segfaulting of the interpreter when an object | |
| created a weakref on itself during a __del__ call for new-style | |
| classes (classic classes still have the bug). | |
| - Bug #1579370: Make PyTraceBack_Here use the current thread, not the | |
| frame's thread state. | |
| - patch #1630975: Fix crash when replacing sys.stdout in | |
| sitecustomize.py. | |
| - Prevent seg fault on shutdown which could occur if an object raised | |
| a warning. | |
| - Bug #1566280: Explicitly invoke threading._shutdown from Py_Main, to | |
| avoid relying on atexit. | |
| - Bug #1590891: random.randrange don't return correct value for big | |
| number. | |
| - Patch #1586791: Better exception messages for some operations on | |
| strings, tuples and lists. | |
| - Bug #1067760: Deprecate passing floats to file.seek. | |
| - Bug #1591996: Correctly forward exception in instance_contains(). | |
| - Bug #1588287: fix invalid assertion for `1,2` in debug builds. | |
| - Bug #1576657: when setting a KeyError for a tuple key, make sure | |
| that the tuple isn't used as the "exception arguments tuple". | |
| - Bug #1565514: SystemError not raised on too many nested blocks. | |
| - Bug #1576174: WindowsError now displays the windows error code | |
| again, no longer the posix error code. | |
| - Patch #1549049: Support long values in structmember, issue warnings | |
| if the assigned value for structmember fields gets truncated. | |
| - Update the peephole optimizer to remove more dead code (jumps after | |
| returns) and inline unconditional jumps to returns. | |
| - Bug #1545497: when given an explicit base, int() did ignore NULs | |
| embedded in the string to convert. | |
| - Bug #1569998: break inside a try statement (outside a loop) is now | |
| recognized and rejected. | |
| - list.pop(x) accepts any object x following the __index__ protocol. | |
| - A number of places, including integer negation and absolute value, | |
| were fixed to not rely on undefined behaviour of the C compiler | |
| anymore. | |
| - Bug #1566800: make sure that EnvironmentError can be called with any | |
| number of arguments, as was the case in Python 2.4. | |
| - Patch #1567691: super() and new.instancemethod() now don't accept | |
| keyword arguments any more (previously they accepted them, but | |
| didn't use them). | |
| - Fix a bug in the parser's future statement handling that led to | |
| "with" not being recognized as a keyword after, e.g., this | |
| statement: from __future__ import division, with_statement | |
| - Bug #1557232: fix seg fault with def f((((x)))) and def f(((x),)). | |
| - Fix %zd string formatting on Mac OS X so it prints negative numbers. | |
| - Allow exception instances to be directly sliced again. | |
| - Bug #1551432: Exceptions do not define an explicit __unicode__ | |
| method. This allows calling unicode() on exceptions classes | |
| directly to succeed. | |
| - Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack. | |
| Also make sure that every exception class has __module__ set to | |
| 'exceptions'. | |
| - Bug #1550983: emit better error messages for erroneous relative | |
| imports (if not in package and if beyond toplevel package). | |
| - Overflow checking code in integer division ran afoul of new gcc | |
| optimizations. Changed to be more standard-conforming. | |
| - Patch #1542451: disallow continue anywhere under a finally. | |
| - Patch #1546288: fix seg fault in dict_equal due to ref counting bug. | |
| - The return tuple from str.rpartition(sep) is (tail, sep, head) where | |
| head is the original string if sep was not found. | |
| - Bug #1520864: unpacking singleton tuples in list comprehensions and | |
| generator expressions (x for x, in ... ) works again. Fixing this | |
| problem required changing the .pyc magic number. This means that | |
| .pyc files generated before 2.5c2 will be regenerated. | |
| - ``with`` and ``as`` are now keywords. | |
| - Bug #1664966: Fix crash in exec if Unicode filename can't be | |
| decoded. | |
| - Issue #1537: Changed GeneratorExit's base class from Exception to | |
| BaseException. | |
| - Issue #1703448: A joined thread could show up in the | |
| threading.enumerate() list after the join() for a brief period until | |
| it actually exited. | |

| - Add a __format__ method to Decimal, to support PEP 3101. | |
| - Add a timing parameter when using trace.Trace to print out | |
| timestamps. | |
| - Issue #1627: httplib now ignores negative Content-Length headers. | |

| connection instead of raising ValueError. | |
| - Issue #1492: The content type of BaseHTTPServer error messages can | |
| now be overridden. | |
| - Issue #1781: ConfigParser now does not let you add the "default" section | |
| (ignore-case) | |
| - Removed uses of dict.has_key() from distutils, and uses of | |
| callable() from copy_reg.py, so the interpreter now starts up | |
| without warnings when '-3' is given. More work like this needs to | |
| be done in the rest of the stdlib. | |
| - Issue #1916: added isgenerator() and isgeneratorfunction() to | |
| inspect.py. | |

| - Patch #1966: Break infinite loop in httplib when the servers | |
| implements the chunked encoding incorrectly. | |
| - Rename rational.py to fractions.py and the rational.Rational class | |
| to fractions.Fraction, to avoid the name clash with the abstract | |
| base class numbers.Rational. See discussion in issue #1682. | |

| eliminates unused PUT opcodes from a pickle string. | |
| - Patch #2021: Allow tempfile.NamedTemporaryFile and | |
| SpooledTemporaryFile to be used in with statements by correctly | |
| supporting the context management protocol. | |

| comparisons involving a NaN follow the IEEE 754 standard. | |
| - Issue #2004: tarfile.py: Use mode 0700 for temporary directories and | |
| default permissions for missing directories. | |
| - Issue #175006: The debugger used to skip the condition of a "while" | |
| statement after the first iteration. Now it correctly steps on the | |
| expression, and breakpoints on the "while" statement are honored on | |
| each loop. | |
| - Issue #1765140: add an optional delay argument to FileHandler and | |
| its subclasses. Defaults to false (existing behaviour), but if true, | |
| defers opening the file until the first call to emit(). | |
| - The pprint module now supports sets and frozensets. | |
| - Issue #1221598: add optional callbacks to ftplib.FTP's storbinary() | |
| and storlines() methods. (Contributed by Phil Schwartz) | |

| in flush(). | |
| - Bug #1530959: distutils' build command now uses different build | |
| directory when building extension modules against versions of Python | |
| compiled with ``--with-pydebug``. | |
| - Issue #1555501: move plistlib from plat-mac directory to general | |
| library. | |
| - Issue #1269: fix a bug in pstats.add_callers() and add a unit test | |
| file for pstats. | |
| - Issue #1669: don't allow shutil.rmtree() to be called on a symlink | |
| to a directory. | |
| - Issue #1664522: in urllib, don't read non-existing directories in | |
| ftp mode, returning a 0-byte file -- raise an IOError instead. | |
| - Issue #856047: respect the ``no_proxy`` environment variable when | |
| using the ``http_proxy`` etc. environment variables in urllib. | |
| - Issue #1178141: add a getcode() method to the addinfourls that | |
| urllib.open() returns so that you can retrieve the HTTP status code. | |
| - Issue #1003: Fix zipfile decryption check, it would fail zip files | |
| with extended local headers. | |

| the last column of a line. | |
| - Issue #1693149: trace.py --ignore-module - accept multiple | |
| comma-separated modules to be given. | |
| - Issue #1822: MIMEMultipart.is_multipart() behaves correctly for a | |
| just-created (and empty) instance. Thanks Jonathan Share. | |
| - Issue #1861: Added an attribute to the sched module which returns an | |
| ordered list of upcoming events (displayed as named tuples). | |
| - Issue #1837: The queue module now also supports a LIFO queue and a | |
| priority queue. | |
| - Patch #1048820: Add insert-mode editing to curses.textpad.Textbox | |
| (patch by Stefan Wehr). Also, fix an off-by-one bug in | |
| Textbox.gather(). | |
| - Issue #1831: ctypes now raises a TypeError if conflicting positional | |
| and named arguments are passed to a Structure or Union initializer. | |
| When too many positional arguments are passed, also a TypeError is | |
| raised instead of a ValueError. | |
| - Convert the internal ctypes array type cache to a WeakValueDict so | |
| that array types do not live longer than needed. | |
| - Issue #1786: pdb should use its own stdin/stdout around an exec call | |
| and when creating a recursive instance. | |
| - Issue #1698398: ZipFile.printdir() crashed because the format string | |
| expected a tuple type of length six instead of time.struct_time | |
| object. | |
| - Issue #1780: The Decimal constructor now accepts arbitrary leading | |
| and trailing whitespace when constructing from a string. | |
| Context.create_decimal no longer accepts trailing newlines. | |
| - Decimal.as_tuple(), difflib.find_longest_match() and inspect | |
| functions that returned a tuple now return a named tuple. | |
| - Doctest now returns results as a named tuple for readability: | |
| (0, 7) --> TestResults(failed=0, attempted=7) | |
| - Issue #846388: re.match is interruptible now, which is particularly | |
| good for long regular expression matches. | |
| - Patch #1137: allow setting buffer_size attribute on pyexpat Parser | |
| objects to set the character data buffer size. | |
| - Issue #1757: The hash of a Decimal instance is no longer affected by | |
| the current context. | |

| writing | |
| - Issue #1700: Regular expression inline flags incorrectly handle | |
| certain unicode characters. | |
| - Issue #1689: PEP 3141, numeric abstract base classes. | |
| - Tk issue #1851526: Return results from Python callbacks to Tcl as | |
| Tcl objects. | |
| - Issue #1642: Fix segfault in ctypes when trying to delete attributes. | |
| - Issue #1727780: Support loading pickles of random.Random objects | |
| created on 32-bit systems on 64-bit systems, and vice versa. As a | |
| consequence of the change, Random pickles created by Python 2.6 | |
| cannot be loaded in Python 2.5. | |
| - Issue #1455: The distutils package now supports VS 2005 and VS 2008 | |
| for both the msvccompiler and cygwincompiler. | |
| - Issue #1531: tarfile.py: Read fileobj from the current offset, do | |
| not seek to the start. | |
| - Issue #1534: Added a dictionary sys.float_info with information | |
| about the internal floating point type to the sys module. | |
| - Issue #1429818: patch for trace and doctest modules so they play | |
| nicely together. | |
| - doctest made a bad assumption that a package's __loader__.get_data() | |
| method used universal newlines. | |
| - Issue #1705170: contextlib.contextmanager was still swallowing | |
| StopIteration in some cases. This should no longer happen. | |
| - Issue #1292: On alpha, arm, ppc, and s390 linux systems the | |
| --with-system-ffi configure option defaults to "yes". | |
| - IN module for FreeBSD 8 is added and preexisting FreeBSD 6 and 7 | |
| files are updated. | |
| - Issues #1181, #1287: unsetenv() is now called when the | |
| os.environ.pop() and os.environ.clear() methods are used. | |
| - ctypes will now work correctly on 32-bit systems when Python is | |
| configured with --with-system-ffi. | |
| - Patch #1203: ctypes now does work on OS X when Python is built with | |
| --disable-toolbox-glue. | |
| - collections.deque() now supports a "maxlen" argument. | |
| - itertools.count() is no longer bounded to LONG_MAX. Formerly, it | |
| raised an OverflowError. Now, automatically shifts from ints to | |
| longs. | |
| - Added itertools.product() which forms the Cartesian product of the | |
| input iterables. | |
| - Added itertools.combinations() and itertools.permutations(). | |
| - Patch #1541463: optimize performance of cgi.FieldStorage operations. | |
| - Decimal is fully updated to the latest Decimal Specification | |
| (v1.66). | |
| - Bug #1153: repr.repr() now doesn't require set and dictionary items | |
| to be orderable to properly represent them. | |
| - A 'c_longdouble' type was added to the ctypes module. | |
| - Bug #1709599: Run test_1565150 only if the file system is NTFS. | |
| - When encountering a password-protected robots.txt file the | |
| RobotFileParser no longer prompts interactively for a username and | |
| password (bug 813986). | |

| the fileobj argument has no usable name attribute (e.g. StringIO). | |
| - The functools module now provides 'reduce', for forward | |
| compatibility with Python 3000. | |
| - Server-side SSL support and cert verification added, by Bill | |
| Janssen. | |
| - socket.ssl deprecated; use new ssl module instead. | |
| - uuid creation is now threadsafe. | |

| sideeffect the representation of these instances has changed. | |
| - tarfile.py: Added "exclude" keyword argument to TarFile.add(). | |
| - Bug #1734723: Fix repr.Repr() so it doesn't ignore the maxtuple | |
| attribute. | |
| - The urlopen function of urllib2 now has an optional timeout | |
| parameter (note that it actually works with HTTP, HTTPS, FTP and | |
| FTPS connections). | |
| - In ftplib, the FTP.ntransfercmd method, when in passive mode, now | |
| uses the socket.create_connection function, using the timeout | |
| specified at connection time. | |
| - Bug #1728403: Fix a bug that CJKCodecs StreamReader hangs when it | |
| reads a file that ends with incomplete sequence and sizehint | |
| argument for .read() is specified. | |
| - Bug #1730389: Change time.strptime() to use ``\s+`` instead of | |
| ``\s*`` when matching spaces in the specified format argument. | |
| - Bugs #1668596/#1720897: distutils now copies data files even if | |
| package_dir is empty. | |
| - sha now raises a DeprecationWarning upon import. | |

| of an infinite recursion check. | |
| - Removed plat-freebsd2 and plat-freebsd3 directories (and IN.py in | |
| the directories). | |

| the traceback inadvertently or maliciously closing the comment and | |
| injecting HTML into the error page. | |

| module. | |
| - Added an optional credentials argument to SMTPHandler, for use with | |
| SMTP servers which require authentication. | |
| - Patch #1695948: Added optional timeout parameter to SocketHandler. | |
| - Bug #1652788: Minor fix for currentframe. | |
| - Patch #1598415: Added WatchedFileHandler to better support external | |
| log file rotation using e.g. newsyslog or logrotate. This handler is | |
| only useful in Unix/Linux environments. | |
| - Bug #1706381: Specifying the SWIG option "-c++" in the setup.py file | |
| (as opposed to the command line) will now write file names ending in | |
| ".cpp" too. | |
| - As specified in RFC 2616, an HTTP response like 2xx indicates that | |
| the client's request was successfully received, understood, and | |
| accepted. Now in these cases no error is raised in urllib (issue | |
| #1177) and urllib2. | |
| - Bug #1290505: time.strptime's internal cache of locale information | |
| is now properly recreated when the locale is changed. | |
| - Patch #1685563: remove (don't add) duplicate paths in | |
| distutils.MSVCCompiler. | |
| - Added a timeout parameter to the constructor of other protocols | |
| (telnetlib, ftplib, smtplib and poplib). This is second part of the | |
| work started with create_connection() and timeout in httplib, and | |
| closes patch #723312. | |
| - Patch #1676823: Added create_connection() to socket.py, which may be | |
| called with a timeout, and use it from httplib (whose HTTPConnection | |
| and HTTPSConnection now accept an optional timeout). | |

| - Patch #1630118: add a SpooledTemporaryFile class to tempfile.py. | |
| - Patch #1273829: os.walk() now has a "followlinks" parameter. If set | |
| to True (which is not the default), it visits symlinks pointing to | |
| directories. | |
| - Bug #1681228: the webbrowser module now correctly uses the default | |
| GNOME or KDE browser, depending on whether there is a session of one | |
| of those present. Also, it tries the Windows default browser before | |
| trying Mozilla variants. | |
| - Patch #1339796: add a relpath() function to os.path. | |
| - Patch #1681153: the wave module now closes a file object it opened if | |
| initialization failed. | |

| AttributeError instead of an IOError when the server's response | |
| didn't contain a valid HTTP status line. | |
| - Patch #957650: "%var%" environment variable references are now | |
| properly expanded in ntpath.expandvars(), also "~user" home | |
| directory references are recognized and handled on Windows. | |
| - Patch #1429539: pdb now correctly initializes the __main__ module | |
| for the debugged script, which means that imports from __main__ work | |
| correctly now. | |

| - Patch #1393667: pdb now has a "run" command which restarts the | |
| debugged Python program, optionally with different arguments. | |
| - Patch #1649190: Adding support for _Bool to ctypes as c_bool. | |
| - Patch #1530482: add pydoc.render_doc() which returns the | |
| documentation for a thing instead of paging it to stdout, which | |
| pydoc.doc() does. | |
| - Patch #1533909: the timeit module now accepts callables in addition | |
| to strings for the code to time and the setup code. Also added two | |
| convenience functions for instantiating a Timer and calling its | |
| methods. | |
| - Patch #1537850: tempfile.NamedTemporaryFile now has a "delete" | |
| parameter which can be set to False to prevent the default | |
| delete-on-close behavior. | |
| - Patch #1581073: add a flag to textwrap that prevents the dropping of | |
| whitespace while wrapping. | |
| - Patch #1603688: ConfigParser.SafeConfigParser now checks values that | |
| are set for invalid interpolation sequences that would lead to | |
| errors on reading back those values. | |
| - Added support for the POSIX.1-2001 (pax) format to | |
| tarfile.py. Extended and cleaned up the test suite. Added a new | |
| testtar.tar. | |

| number. | |
| - Patch #1599845: Add an option to disable the implicit calls to | |
| server_bind() and server_activate() in the constructors for | |
| TCPServer, SimpleXMLRPCServer and DocXMLRPCServer. | |
| - Bug #1531963: Make SocketServer.TCPServer's server_address always be | |
| equal to calling getsockname() on the server's socket. Fixed by | |
| patch #1545011. | |
| - Patch #742598: Add .timeout attribute to SocketServer that calls | |
| .handle_timeout() when no requests are received. | |
| - Bug #1651235: When a tuple was passed to a ctypes function call, | |
| Python would crash instead of raising an error. | |
| - Bug #1646630: ctypes.string_at(buf, 0) and ctypes.wstring_at(buf, 0) | |
| returned string up to the first NUL character. | |
| - Patch #957003: Implement smtplib.LMTP. | |
| - Patch #1481079: add support for HTTP_REFERER to CGIHTTPServer. | |

| names now has a descriptive message. | |
| - Bug #1115886: os.path.splitext('.cshrc') gives now ('.cshrc', ''). | |
| - unittest now verifies more of its assumptions. In particular, | |
| TestCase and TestSuite subclasses (not instances) are no longer | |
| accepted in TestSuite.addTest(). This should cause no | |
| incompatibility since it never made sense with ordinary subclasses | |
| -- the failure just occurred later, with a more cumbersome | |
| exception. | |
| - Patch #787789: allow passing custom TestRunner instances to | |
| unittest's main() function. | |
| - Patches #1550273, #1550272: fix a few bugs in unittest and add a | |
| comprehensive test suite for the module. | |
| - Patch #1001604: glob.glob() now returns unicode filenames if it was | |
| given a unicode argument and os.listdir() returns unicode filenames. | |
| - Patch #1673619: setup.py identifies extension modules it doesn't | |
| know how to build and those it knows how to build but that fail to | |
| build. | |

| - Patch #1652681: tarfile.py: create nonexistent files in append mode | |
| and allow appending to empty files. | |
| - Bug #1124861: Automatically create pipes if GetStdHandle fails in | |
| subprocess. | |
| - Patch #1634778: add missing encoding aliases for iso8859_15 and | |
| iso8859_16. | |
| - Patch #1638243: the compiler package is now able to correctly | |
| compile a with statement; previously, executing code containing a | |

| interpreter. | |
| - Bug #1643943: Fix time.strptime's support for the %U directive. | |
| - Patch #1507247: tarfile.py: use current umask for intermediate | |
| directories. | |
| - Patch #1627441: close sockets properly in urllib2. | |
| - Bug #494589: make ntpath.expandvars behave according to its | |
| docstring. | |
| - Changed platform module API python_version_tuple() to actually | |
| return a tuple (it used to return a list). | |
| - Added new platform module APIs python_branch(), python_revision(), | |
| python_implementation() and linux_distribution(). | |
| - Added support for IronPython and Jython to the platform module. | |
| - The sets module has been deprecated. Use the built-in set/frozenset | |
| types instead. | |
| - Bug #1610795: make ctypes.util.find_library work on BSD systems. | |
| - Fixes for 64-bit Windows: In ctypes.wintypes, correct the | |
| definitions of HANDLE, WPARAM, LPARAM data types. Make | |
| parameterless foreign function calls work. | |
| - The version number of the ctypes package changed to "1.1.0". | |
| - Bug #1627575: logging: Added _open() method to FileHandler which can | |
| be used to reopen files. The FileHandler instance now saves the | |
| encoding (which can be None) in an attribute called "encoding". | |
| - Bug #411881: logging.handlers: bare except clause removed from | |
| SMTPHandler.emit. Now, only ImportError is trapped. | |

| weren't passing the message factory on to newly created Maildir/MH | |
| objects. | |
| - Patch #1514543: mailbox.py: In the Maildir class, report errors if | |
| there's a filename clash instead of possibly losing a message. | |
| (Patch by David Watson.) | |
| - Patch #1514544: Try to ensure that messages/indexes have been | |

| list comprehensions as the built-in compiler, using the LIST_APPEND | |
| opcode. | |
| - Fix codecs.EncodedFile which did not use file_encoding in 2.5.0, and | |
| fix all codecs file wrappers to work correctly with the "with" | |
| statement (bug #1586513). | |
| - Lib/modulefinder.py now handles absolute and relative imports | |
| correctly. | |
| - Patch #1567274: Support SMTP over TLS. | |
| - Patch #1560695: Add .note.GNU-stack to ctypes' sysv.S so that ctypes | |
| isn't considered as requiring executable stacks. | |
| - ctypes callback functions only support 'fundamental' data types as | |
| result type. Raise an error when something else is used. This is a | |
| partial fix for Bug #1574584. | |
| - Fix turtle so that time.sleep is imported for the entire library. | |
| Allows the demo2 function to be executed on its own instead of only | |
| when the module is run as a script. | |

| - Support for MSVC 8 was added to bdist_wininst. | |
| - Bug #1446043: correctly raise a LookupError if an encoding name | |
| given to encodings.search_function() contains a dot. | |
| - Bug #1560617: in pyclbr, return full module name not only for | |
| classes, but also for functions. | |
| - Bug #1457823: cgi.(Sv)FormContentDict's constructor now takes | |
| keep_blank_values and strict_parsing keyword arguments. | |
| - Bug #1566602: correct failure of posixpath unittest when $HOME ends | |
| with a slash. | |
| - Bug #1565661: in webbrowser, split() the command for the default | |
| GNOME browser in case it is a command with args. | |
| - Made the error message for time.strptime when the data and | |
| format do match be more clear. | |
| - Fix a bug in traceback.format_exception_only() that led to an error | |
| being raised when print_exc() was called without an exception set. | |
| In version 2.4, this printed "None", restored that behavior. | |
| - Make webbrowser.BackgroundBrowser usable in Windows (it wasn't | |
| because the close_fds arg to subprocess.Popen is not supported). | |
| - Reverted patch #1504333 to sgmllib because it introduced an infinite | |
| loop. | |
| - Patch #1553314: Fix the inspect.py slowdown that was hurting IPython | |
| & SAGE by adding smarter caching in inspect.getmodule() | |

| the first chunk fed to the decoder started with a BOM, but was | |
| longer than 3 bytes. | |
| - The implementation of UnicodeError objects has been simplified | |
| (start and end attributes are now stored directly as Py_ssize_t | |
| members). | |
| - Issue #829951: In the smtplib module, SMTP.starttls() now complies | |
| with RFC 3207 and forgets any knowledge obtained from the server not | |
| obtained from the TLS negotiation itself. Patch contributed by Bill | |
| Fenner. | |
| - Issue #1339: The smtplib.SMTP class has been refactored a bit such | |
| that the SMTP.starttls() caller no longer needs to call ehlo() | |
| beforehand. SMTP.starttls() now raises an exception of the server | |
| does not claim to support starttls. Adds the | |
| SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill | |
| Fenner. | |
| - Patch #1089358: Add signal.siginterrupt, a wrapper around | |
| siginterrupt(3). | |

| - Patch #1736: Fix file name handling of _msi.FCICreate. | |
| - Updated ``big5hkscs`` codec to the HKSCS revision of 2004. | |
| - Issue #1940: make it possible to use curses.filter() before | |
| curses.initscr() as the documentation says. | |
| - Backport of _fileio module from Python 3.0. | |
| - Patch #1087741: mmap.mmap is now a class, not a factory function. It | |
| is also subclassable now. | |
| - Patch #1648: added ``sys.getprofile()`` and ``sys.gettrace()``. | |
| - Patch #1663329: added ``os.closerange()`` function to quickly close | |
| a range of file descriptors without considering errors. | |
| - Patch #976880: ``mmap`` objects now have an ``rfind`` method that | |
| works as expected. ``mmap.find`` also takes an optional ``end`` | |
| parameter. | |
| - _winreg's HKEY object has gained __enter__ and __exit__ methods to | |
| support the context management protocol. The _winreg module also | |
| gained a new function ``ExpandEnvironmentStrings`` to expand | |
| REG_EXPAND_SZ keys. | |
| - itertools.starmap() now accepts any iterable input. Previously, it | |
| required the function inputs to be tuples. | |
| - itertools.chain() now has an alternate constructor, | |
| chain.from_iterable(). | |
| - Issue #1646: Make socket support TIPC. The socket module now has | |
| support for TIPC under Linux, see http://tipc.sf.net/ for more | |
| information. | |
| - Added interface for Windows' WSAIoctl to socket object and added an | |
| example for a simple network sniffer. | |
| - Bug #1301: Bad assert in _tkinter fixed. | |
| - Added bdist_wininst executable for VS 2008. | |
| - Bug #1604: collections.deque.__init__(iterable) now clears any prior | |
| contents before adding elements from the iterable. This fix brings | |
| the behavior into line with that for list.__init__(). | |
| - Added wide char functions to msvcrt module: getwch, getwche, putwch | |
| and ungetwch. The functions accept or return unicode. | |
| - os.access now returns True on Windows for any existing directory. | |
| - Added warnpy3k function to the warnings module. | |
| - Marshal.dumps() now expects exact type matches for int, long, float, | |
| complex, tuple, list, dict, set, and frozenset. Formerly, it would | |
| silently miscode subclasses of those types. Now, it raises a | |
| ValueError instead. | |
| - Patch #1388440: Add set_completion_display_matches_hook and | |
| get_completion_type to readline. | |
| - Bug #1649098: Avoid declaration of zero-sized array declaration in | |

| - Bug #1233: fix bsddb.dbshelve.DBShelf append method to work as | |
| intended for RECNO databases. | |
| - pybsddb.sf.net Bug #477182: Load the database flags at database open | |
| time so that opening a database previously created with the DB_DUP | |
| or DB_DUPSORT flag set will keep the proper behavior on subsequent | |
| opens. Specifically: dictionary assignment to a DB object will | |
| replace all values for a given key when the database allows | |
| duplicate values. DB users should use DB.put(k, v) when they want | |
| to store duplicates; not DB[k] = v. | |
| - Add the bsddb.db.DBEnv.lock_id_free method. | |
| - Bug #1686475: Support stat'ing open files on Windows again. | |
| - Patch #1185447: binascii.b2a_qp() now correctly quotes binary | |
| characters with ASCII value less than 32. Also, it correctly quotes | |
| dots only if they occur on a single line, as opposed to the previous | |
| behavior of quoting dots if they are the second character of any | |
| line. | |

| returned when a socket timeout is set and a connection attempt | |
| fails. | |
| - Speed up function calls into the math module. | |
| - Bug #1588217: don't parse "= " as a soft line break in binascii's | |

| codepoints now. | |
| - Bug #1552726: in readline.c, avoid repeatedly polling in interactive | |
| mode by only placing a timeout on the select() if an input hook has | |
| been defined. This prevents an interactive Python from waking up 10 | |
| times per second. Patch by Richard Boulton. | |

| Tests | |
| ----- | |
| - Refactor test_logging to use unittest. | |
| - Refactor test_profile and test_cprofile to use the same code to | |
| profile. | |
| - Make test_runpy reentrant by fixing _check_module to clear out any | |
| module being tested. Was causing an error by __import__ doing a | |
| reload on the second run and thus suppressing bytecode recreation. | |
| - Capture socket connection resets and timeouts in test_socket_ssl and | |
| test_urllib2net and raise test.test_support.ResourceDenied. | |
| - Patch #1559413: Fix test_cmd_line if sys.executable contains a | |
| space. | |
| - Added test.test_support.TransientResource which is a context manager | |
| to surround calls to resources that are not guaranteed to work even | |
| if test.test_support.requires says that the resource should exist. | |
| - Added a test for slicing of an exception. | |
| - Added test.test_support.EnvironmentVarGuard. It's a class that | |
| provides a context manager so that one can temporarily set or unset | |
| environment variables. | |
| - Added some tests for modulefinder. | |
| - Converted test_imp to use unittest. | |
| - Fix bsddb test_basics.test06_Transactions to check the version | |
| number properly. | |
| - test.test_support.catch_warning is a new context manager that can be | |
| used to catch the warnings issued by the warning framework. | |
| Tools | |
| ----- | |
| - Tools/scripts/reindent.py now creates the backup file using | |
| shutil.copy to preserve user/group and permissions. Added also a | |
| --nobackup option to not create the backup if the user is concerned | |
| regarding this. Check issue #1050828 for more details. | |
| - Tools/scripts/win_add2path.py was added. The simple script modifes | |
| the PATH environment var of the HKCU tree and adds the python bin | |
| and script directory. | |
| - Tools/18n/pygettext.py was added to the list of scripts installed by | |
| Tools/scripts/setup.py (tracker item 642309). | |
| - Added IronPython and Jython support to pybench (part of which was | |
| patch #1563844). | |
| - Made some minor changes to pybench output to allow the user to see | |
| which Python version is running pybench. | |
| - Added support for the new platform module feature | |
| platform.python_implementation(); this will now be saved in the | |
| benchmark pickle. | |

| file not to get reported properly. | |
| Build | |
| ----- | |
| - Have the search path for building extensions follow the declared | |
| order in $CPPFLAGS and $LDFLAGS when adding directories from those | |
| environment variables. | |
| - Bug #1983: Added a check to pyport to verify that sizeof(pid_t) is | |
| smaller or equal sizeof(long). | |
| - Bug #1234: Fixed semaphore errors on AIX 5.2 | |
| - Issue #1726: Remove Python/atof.c from PCBuild/pythoncore.vcproj. | |
| - Removed PCbuild8/ directory and added a new build directory for VS | |
| 2005 based on the VS 2008 build directory to PC/VS8.0. The script | |
| PCbuild/vs8to9.py was added to sync changes from PCbuild to | |
| PC/VS8.0. | |
| - Moved PCbuild/ directory for VS 2003 to PC/VS7.1 and renamed | |
| PCBuild9/ directory to PCBuild/. | |
| - Bug #1699: Define _BSD_SOURCE only on OpenBSD. | |
| - Bug #1608: use -fwrapv when GCC supports it. This is important, | |
| newer GCC versions may optimize away overflow buffer overflow checks | |
| without this option! | |
| - Patch #1418: Make the AC_REPLACE_FUNCS object files actually work. | |
| - Add a FAST_LOOPS build option that speeds-up looping by trading away | |
| periodic threadstate and signal checking in tight loops. By | |
| default, this option is turned-off. It should only be enabled in | |
| debugged, performance critical applications. | |
| - Patch #786737: Allow building in a tree of symlinks pointing to a | |
| readonly source. | |
| - Bug #1737210: Change Manufacturer of Windows installer to PSF. | |
| - Bug #1746880: Correctly install DLLs into system32 folder on Win64. | |
| - Define _BSD_SOURCE, to get access to POSIX extensions on OpenBSD | |
| 4.1+. | |
| - Stop supporting AtheOS and cause a build error in configure for the | |
| platform. | |
| - Bug #1655392: don't add -L/usr/lib/pythonX.Y/config to the LDFLAGS | |
| returned by python-config if Python was built with --enable-shared | |
| because that prevented the shared library from being used. | |
| - Patch #1569798: fix a bug in distutils when building Python from a | |
| directory within sys.exec_prefix. | |
| - Bug #1675511: Use -Kpic instead of -xcode=pic32 on Solaris/x86. | |
| - Disable _XOPEN_SOURCE on NetBSD 1.x. | |
| - configure now checks whether gcc supports the PyArg_ParseTuple | |
| format attribute. | |
| - Bug #1578513: Cross compilation was broken by a change to configure. | |
| Repair so that it's back to how it was in 2.4.3. | |
| - Patch #1576954: Update VC6 build directory; remove redundant files | |
| in VC7. | |
| - Bug #1568842: Fix test for uintptr_t. | |
| - Patch #1540470: for OpenBSD 4.0. | |
| - Fix build failure on kfreebsd and on the hurd. | |

| - Allow Emacs 22 for building the documentation in info format. | |
| - Makefile.pre.in(buildbottest): Run an optional script | |
| pybuildbot.identify to include some information about the build | |
| environment. | |
| C API | |
| ----- | |
| - Unified naming convention for free lists and their limits. All free | |
| lists in Object/ are named ``free_list``, the counter ``numfree`` | |
| and the upper limit is a macro ``PyName_MAXFREELIST`` inside an | |
| #ifndef block. | |
| - ``PySet_Add()`` can now modify a newly created frozenset. Similarly | |
| to ``PyTuple_SetItem``, it can be used to populate a brand new | |
| frozenset; but it does not steal a reference to the added item. | |
| - Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API. | |
| - Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format | |
| and _FormatV from Python 3.0. Made PyLong_AsSsize_t and | |
| PyLong_FromSsize_t public functions. | |
| - Patch #1720595: add T_BOOL to the range of structmember types. | |
| - Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and | |
| ``PyFloat_GetInfo()`` to the float API. | |
| - Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t# | |
| of w# format code incorrectly truncated the length to an int, even | |
| when PY_SSIZE_T_CLEAN is set. The str.decode method used to return | |
| incorrect results with huge strings. | |
| - Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE, | |
| Py_TYPE and Py_REFCNT. | |
| - PEP 3123: Provide forward compatibility with Python 3.0, while | |
| keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size, | |
| and PyVarObject_HEAD_INIT. | |
| - Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not | |
| defined. | |
| - Patch #1733960: Allow T_LONGLONG to accept ints. | |
| - T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members. | |
| - Added a new API function ``PyImport_ImportModuleNoBlock``. | |
| - Bug #1637022: Prefix AST symbols with _Py_. | |
| - Fix some leftovers from the conversion from int to Py_ssize_t | |
| (relevant to strings and sequences of more than 2**31 items). | |
| - Make _PyGILState_NoteThreadState() static, it was not used anywhere | |
| outside of pystate.c and should not be necessary. | |
| - ``PyImport_Import`` and ``PyImport_ImportModule`` now always do | |
| absolute imports. In earlier versions they might have used relative | |
| imports under some conditions. | |
| - Added case insensitive comparison methods ``PyOS_stricmp(char*, | |
| char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``. | |
| - Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx | |
| macro so it can be used as an expression. | |
| Windows | |
| ------- | |
| - Patch #1706: Drop support for Win9x, WinME and NT4. Python now | |
| requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION | |
| macros are set to Win2k for x86/32bit builds and WinXP for AMD64 | |
| builds. | |
| - Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and | |
| _CRT_NONSTDC_NO_DEPRECATE. | |
| - Bug #1216: Restore support for Visual Studio 2002. | |
| Mac | |
| --- | |
| - cfmfile now raises a DeprecationWarning. | |
| - buildtools now raises a DeprecationWarning. | |
| - Removed the macfs module. It had been deprecated since Python 2.5. | |
| This lead to the deprecation of macostools.touched() as it relied | |
| solely on macfs and was a no-op under OS X. | |
