+
+ Release version 0.8.3 with the following changes:
+ * Issue #34: Move zconf.h, zlib.h, and adler32.c into a zlib subdirectory to
+ avoid conflicts with other revisions of these files included in Chromium.
+ Please see: http://codereview.chromium.org/9555002/
+ * Issue #32: Fix erroneous parameter in unit test.
+
+Tue, 27 Sep 2011 10:30:38 -0700 Google Inc. <opensource@google.com>
+
+ Release version 0.8.2 with the following changes:
+ * Issue #29: Include public header format_extension_flags.h in the Debian
+ package libvcdenc-dev.
+ * Issue #31: Add missing license text to codetablewriter_interface.h and to
+ the packaging scripts.
+
+Fri, 6 Aug 2010 11:36:36 -0800 Google Inc. <opensource@google.com>
+
+ Release version 0.8.1 with the following change:
+ * Issue #24: Revert the fix for Issue #21, which caused a regression
+ (the Debian package did not properly install the vcdiff executable.)
+ This version of open-vcdiff builds and tests successfully using MinGW 5.1.6,
+ so Issue #21 is no longer a problem.
+ * Fix warning in autogen.sh by providing only one directory argument to
+ AC_CONFIG_MACRO_DIR. The subordinate directory gflags/m4 is still
+ specified as an -I argument to aclocal.
+
+Tue, 3 Aug 2010 10:44:32 -0800 Google Inc. <opensource@google.com>
+
+ Release version 0.8 with the following changes:
+ * Issue #12: Truncate decoded_target_ after decoding each window, rather than
+ after each call to DecodeChunk(). This helps limit memory usage when
+ processing multiple windows.
+ * Issue #22: To work around a bug in the gold linker
+ (http://sourceware.org/bugzilla/show_bug.cgi?id=10238), list all direct
+ library dependencies in Makefile.am.
+ * Issue #23: Add an option for the encoder to produce simple JSON output
+ instead of VCDIFF (RFC 3284) format.
+ * Issue #25: Enable VCDIFF_USE_BLOCK_COMPARE_WORDS for the PowerPC
+ architecture as well as for x86. The test
+ BlockContentsMatchIsAsFastAsBlockCompareWords failed on a PowerPC machine
+ running AIX 5.3.8.
+ * Issue #28: Only call string::reserve() when the required capacity is greater
+ than the string's current capacity.
+ * Get rid of ExitFatal(). It is no longer used for anything since the custom
+ test framework was replaced with gtest.
+ * Get rid of the match count feature.
+ * Rename the log macros: for example, LOG(ERROR) is now VCD_ERROR.
+ Rename COMPILE_ASSERT to VCD_COMPILE_ASSERT.
+ * Simplify RollingHash by performing its sanity checks at compile time.
+ * The googletest package is now referenced as an svn:externals property.
+ Remove the branched googletest sources from src/gtest and instead reference
+ the source files in the top-level gtest directory.
+ * Likewise, the google-gflags package is now referenced as an svn:externals
+ property. Remove the branched gflags sources from src/gflags and instead
+ reference the source files in the top-level gflags directory.
+ * Use version 1.11 of Automake.
+ * Explicitly include the m4 directory in configuration scripts.
+ * Call LT_INIT from configure.ac as suggested by libtool.
+ * Don't distribute gflags and gtest documents whose names conflict with the
+ same documents in the open-vcdiff package.
+ * Only define _XOPEN_SOURCE if not already defined.
+ * Fix warnings that appeared when compiling on RedHat 9 with gcc 3.2.2:
+ src/encodetable_test.cc:111: warning: cannot pass objects of non-POD
+ type `struct std::string' through `...'; call will abort at runtime
+ * Fix Visual Studio compiler warning about mismatch between size_t and int
+ in blockhash_test.cc.
+ * Add contributors' names to THANKS file.
+
+Fri, 09 Oct 2009 10:32:10 -0700 Google Inc. <opensource@google.com>
+
+ Release version 0.7 with the following changes:
+ * Fix a case in which VarintBE::Parse would read off the end of available
+ input if the variable-length integer began with leading zero bytes
+ with their continuation bits set (0x80 bytes.)
+ * Define std::string as string only within namespaces and class definitions
+ in case there is a string class defined at the outermost scope. If that
+ is the case, the HAS_GLOBAL_STRING label should be defined manually.
+ * Update with changes to gflags package as of 2009/07/23.
+
+Thu, 09 Apr 2009 09:16:58 -0700 Google Inc. <opensource@google.com>
+
+ Release version 0.6 with the following changes:
+ * Issue #9: Add option to optimize VCDIFF decoder when VCD_TARGET will not be
+ used as source segment.
+ Add new interface SetAllowVcdTarget to control whether the VCD_TARGET flag
+ may be used. If this option is set to false and the decoder finds a
+ VCD_TARGET flag, it will issue an error and refuse to continue decoding.
+ * Issue #19: ERROR: Length of target window (100001916) exceeds limit of
+ 67108864 bytes
+ Remove the limit of INT32_MAX on the value of --max_target_file_size, since
+ the new SetAllowVcdTarget feature means that the entire target file will not
+ need to be kept in memory. Separate vcdecoder_test into five test targets,
+ one of which is devoted to the new SetAllowVcdTarget feature. Get rid of
+ kMaxBufferSize and kDefaultBufferSize, which were used ambiguously. A new
+ constant kDefaultMaxTargetSize provides the default values for the
+ --max_target_file_size and --max_target_window_size options. The
+ --buffersize option, if specified, should control the buffer size used,
+ without limits on its value.
+ * Issue #21: Fail to test on MinGW 5.1.4
+ The wrapper executables produced by libtool failed on MinGW with the error
+ "File /bin/sh not found". Add the option AC_DISABLE_FAST_INSTALL to avoid
+ creating wrapper executables. The option implies an extra link step during
+ "make install", but the package is small enough that this does not take
+ long.
+ * Remove the annotated-output feature from the decoder.
+ * Automatically detect and work around a Solaris 10 bug which causes the error
+ "libstdc++.la is not a valid libtool archive".
+ http://whocares.de/2006/05/solaris-10-fixup-for-libstdcla-is-not-a-valid-libtool-archive/
+ * Update with latest changes to gflags package.
+ * Fix type-conversion warning in vcdiff_main.cc in 32-bit Visual Studio build.
+
+Wed, 18 Mar 2009 14:28:23 -0700 Google Inc. <opensource@google.com>
+
+ * Issue #14: HashedDictionary may free memory twice if implicitly copied.
+ * Add private copy constructor and assignment operator for HashedDictionary.
+ * Issue #18: Building RPM package fails on Fedora 9: Installed (but
+ unpackaged) file vcdiff.1.gz.
+ * Some OS, including Fedora 9, automatically compress man pages that are
+ installed using /usr/bin/install. This confuses the RPM packager, which
+ expects a file named "vcdiff.1" and finds one named "vcdiff.1.gz" instead.
+ Use a wild-card character to accept either of these two alternatives.
+ * Change the VCDIFF block size to 16, but have the encoder discard all matches
+ smaller than 32 bytes. This doubles the CPU and memory needed by the
+ encoder, but finds better string matches, producing a more efficient
+ encoding. Loosen the timing test limit in blockhash_test.cc for the debug
+ build only.
+ * Make the code table writer a virtual interface.
+ * Add an interface SetTargetMatching() to the simple encoder class
+ VCDEncoder.
+ * Remove all references to LOG and logging.h from the unit tests and
+ command-line client.
+ * Remove all special cases for kBlockSize < 4. kBlockSize must be a multiple
+ of the machine word size (see blockhash.cc), so it will never be smaller
+ than 4.
+ * Use version 1.10 of Automake.
+ * Incorporate recent changes to gflags package
+ (http://code.google.com/p/google-gflags/)
+ * Fix Visual Studio type-mismatch warning in vcdecoder4_test.cc.
+ * Use address cache helper functions IsSameMode(), IsHereMode(), etc. to
+ simplify test code.
+ * Add contributor's name to THANKS file.
+
+Thu, 23 Oct 2008 09:03:56 -0700 Google Inc. <opensource@google.com>
+
+ * Issue #6: vcdiff crashes with zero-size dictionary
+ * Add special cases for empty dictionary file in vcdiff_main.cc.
+ * Issue #7: vcdiff incorrect binary I/O on Windows
+ * Change stdin/stdout file type to binary in vcdiff_main.cc.
+ * Issue #13: Add unit test for vcdiff command-line executable
+ * Unit test vcdiff_test.bat added for Visual Studio testing of vcdiff.exe.
+ Includes regression tests for issues #6 and #7.
+ * Issue #15: open-vcdiff fails to compile on Fedora 9
+ * Apply patch sent by Daniel Kegel
+ * Add header <string.h> to src/vcdiffengine.cc, which uses memcpy.
+ * Remove const qualifier from integral return types to fix gcc 4.3.1
+ warning.
+ * Add contributors' names to THANKS file.
+
+Fri, 10 Oct 2008 11:16:23 -0700 Google Inc. <opensource@google.com>
+
+ * Issue #15: open-vcdiff fails to compile on Fedora 9
+ * Add header <string.h> to source files that use memcmp, memset, memcpy,
+ and/or strlen.
+ * Change C++-style includes like <cstdlib> to C-style includes like
+ <stdlib.h> so that function names are guaranteed to be defined
+ in the global namespace.
+ * Issue #8: Decoder should not crash if it runs out of memory
+ * Add a new interface that places a limit on the maximum bytes allowed in
+ a single target window or a target file.
+ * Issue #13: Add unit test for vcdiff command-line executable
+ * Unit test vcdiff_test.sh added for Linux and Mac builds.
+ * Still need to add a Windows version of this test.
+
+Tue, 02 Sep 2008 09:27:54 -0700 Google Inc. <opensource@google.com>
+
+ * Fix problems found on OpenBSD platform.
+ * Issue #1: vcdiff command-line executable crashes on startup.
+ This was a problem with the stub intended to replace pthread_once if the
+ package was not linked with the pthreads library. Simplify gflags.cc to
+ assume single-threaded execution.
+ * Issue #2: Unit test blockhash_test fails.
+ Define VCDIFF_USE_BLOCK_COMPARE_WORDS for BSD platforms to ensure that
+ the most efficient version of memcmp is used in the encoder's inner loop.
+ * Fix compilation warnings in gtest-filepath.cc: "warning: missing
+ initializer for member 'stat::...'"
+
+Mon, 16 Jun 2008 15:15:51 -0700 Google Inc. <opensource@google.com>
+
+ * open-vcdiff: initial release:
+ The open-vcdiff package provides an encoder and decoder for the VCDIFF format
+ described in RFC 3284 (http://www.ietf.org/rfc/rfc3284.txt).

+Installation Instructions
+*************************

+without warranty of any kind.
+
+Basic Installation
+==================
+
+ Briefly, the shell commands `./configure; make; make install' should
+configure, build, and install this package. The following
+more-detailed instructions are generic; see the `README' file for
+instructions specific to this package. Some packages provide this
+`INSTALL' file but do not implement all of the features documented
+below. The lack of an optional feature in a given package is not
+necessarily a bug. More recommendations for GNU packages can be found
+in *note Makefile Conventions: (standards)Makefile Conventions.
+
+ The `configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation. It uses
+those values to create a `Makefile' in each directory of the package.
+It may also create one or more `.h' files containing system-dependent
+definitions. Finally, it creates a shell script `config.status' that
+you can run in the future to recreate the current configuration, and a
+file `config.log' containing compiler output (useful mainly for
+debugging `configure').
+
+ It can also use an optional file (typically called `config.cache'
+and enabled with `--cache-file=config.cache' or simply `-C') that saves
+the results of its tests to speed up reconfiguring. Caching is
+disabled by default to prevent problems with accidental use of stale
+cache files.
+
+ If you need to do unusual things to compile the package, please try
+to figure out how `configure' could check whether to do them, and mail
+diffs or instructions to the address given in the `README' so they can
+be considered for the next release. If you are using the cache, and at
+some point `config.cache' contains results you don't want to keep, you
+may remove or edit it.
+
+ The file `configure.ac' (or `configure.in') is used to create
+`configure' by a program called `autoconf'. You need `configure.ac' if
+you want to change it or regenerate `configure' using a newer version
+of `autoconf'.
+
+ The simplest way to compile this package is:
+
+ 1. `cd' to the directory containing the package's source code and type
+ `./configure' to configure the package for your system.
+
+ Running `configure' might take a while. While running, it prints
+ some messages telling which features it is checking for.
+
+ 2. Type `make' to compile the package.
+
+ 3. Optionally, type `make check' to run any self-tests that come with
+ the package, generally using the just-built uninstalled binaries.
+
+ 4. Type `make install' to install the programs and any data files and
+ documentation. When installing into a prefix owned by root, it is
+ recommended that the package be configured and built as a regular
+ user, and only the `make install' phase executed with root
+ privileges.
+
+ 5. Optionally, type `make installcheck' to repeat any self-tests, but
+ this time using the binaries in their final installed location.
+ This target does not install anything. Running this target as a
+ regular user, particularly if the prior `make install' required
+ root privileges, verifies that the installation completed
+ correctly.
+
+ 6. You can remove the program binaries and object files from the
+ source code directory by typing `make clean'. To also remove the
+ files that `configure' created (so you can compile the package for
+ a different kind of computer), type `make distclean'. There is
+ also a `make maintainer-clean' target, but that is intended mainly
+ for the package's developers. If you use it, you may have to get
+ all sorts of other programs in order to regenerate files that came
+ with the distribution.
+
+ 7. Often, you can also type `make uninstall' to remove the installed
+ files again. In practice, not all packages have tested that
+ uninstallation works correctly, even though it is required by the
+ GNU Coding Standards.
+
+ 8. Some packages, particularly those that use Automake, provide `make
+ distcheck', which can by used by developers to test that all other
+ targets like `make install' and `make uninstall' work correctly.
+ This target is generally not run by end users.
+
+Compilers and Options
+=====================
+
+ Some systems require unusual options for compilation or linking that
+the `configure' script does not know about. Run `./configure --help'
+for details on some of the pertinent environment variables.
+
+ You can give `configure' initial values for configuration parameters
+by setting variables in the command line or in the environment. Here
+is an example:
+
+ ./configure CC=c99 CFLAGS=-g LIBS=-lposix
+
+ *Note Defining Variables::, for more details.
+
+Compiling For Multiple Architectures
+====================================
+
+ You can compile the package for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory. To do this, you can use GNU `make'. `cd' to the
+directory where you want the object files and executables to go and run
+the `configure' script. `configure' automatically checks for the
+source code in the directory that `configure' is in and in `..'. This
+is known as a "VPATH" build.
+
+ With a non-GNU `make', it is safer to compile the package for one
+architecture at a time in the source code directory. After you have
+installed the package for one architecture, use `make distclean' before
+reconfiguring for another architecture.
+
+ On MacOS X 10.5 and later systems, you can create libraries and
+executables that work on multiple system types--known as "fat" or
+"universal" binaries--by specifying multiple `-arch' options to the
+compiler but only a single `-arch' option to the preprocessor. Like
+this:
+
+ ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
+ CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
+ CPP="gcc -E" CXXCPP="g++ -E"
+
+ This is not guaranteed to produce working output in all cases, you
+may have to build one architecture at a time and combine the results
+using the `lipo' tool if you have problems.
+
+Installation Names
+==================
+
+ By default, `make install' installs the package's commands under
+`/usr/local/bin', include files under `/usr/local/include', etc. You
+can specify an installation prefix other than `/usr/local' by giving
+`configure' the option `--prefix=PREFIX', where PREFIX must be an
+absolute file name.
+
+ You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files. If you
+pass the option `--exec-prefix=PREFIX' to `configure', the package uses
+PREFIX as the prefix for installing programs and libraries.
+Documentation and other data files still use the regular prefix.
+
+ In addition, if you use an unusual directory layout you can give
+options like `--bindir=DIR' to specify different values for particular
+kinds of files. Run `configure --help' for a list of the directories
+you can set and what kinds of files go in them. In general, the
+default for these options is expressed in terms of `${prefix}', so that
+specifying just `--prefix' will affect all of the other directory
+specifications that were not explicitly provided.
+
+ The most portable way to affect installation locations is to pass the
+correct locations to `configure'; however, many packages provide one or
+both of the following shortcuts of passing variable assignments to the
+`make install' command line to change installation locations without
+having to reconfigure or recompile.
+
+ The first method involves providing an override variable for each
+affected directory. For example, `make install
+prefix=/alternate/directory' will choose an alternate location for all
+directory configuration variables that were expressed in terms of
+`${prefix}'. Any directories that were specified during `configure',
+but not in terms of `${prefix}', must each be overridden at install
+time for the entire installation to be relocated. The approach of
+makefile variable overrides for each directory variable is required by
+the GNU Coding Standards, and ideally causes no recompilation.
+However, some platforms have known limitations with the semantics of
+shared libraries that end up requiring recompilation when using this
+method, particularly noticeable in packages that use GNU Libtool.
+
+ The second method involves providing the `DESTDIR' variable. For
+example, `make install DESTDIR=/alternate/directory' will prepend
+`/alternate/directory' before all installation names. The approach of
+`DESTDIR' overrides is not required by the GNU Coding Standards, and
+does not work on platforms that have drive letters. On the other hand,
+it does better at avoiding recompilation issues, and works well even
+when some directory options were not specified in terms of `${prefix}'
+at `configure' time.
+
+Optional Features
+=================
+
+ If the package supports it, you can cause programs to be installed
+with an extra prefix or suffix on their names by giving `configure' the
+option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
+
+ Some packages pay attention to `--enable-FEATURE' options to
+`configure', where FEATURE indicates an optional part of the package.
+They may also pay attention to `--with-PACKAGE' options, where PACKAGE
+is something like `gnu-as' or `x' (for the X Window System). The
+`README' should mention any `--enable-' and `--with-' options that the
+package recognizes.
+
+ For packages that use the X Window System, `configure' can usually
+find the X include and library files automatically, but if it doesn't,
+you can use the `configure' options `--x-includes=DIR' and
+`--x-libraries=DIR' to specify their locations.
+
+ Some packages offer the ability to configure how verbose the
+execution of `make' will be. For these packages, running `./configure
+--enable-silent-rules' sets the default to minimal output, which can be
+overridden with `make V=1'; while running `./configure
+--disable-silent-rules' sets the default to verbose, which can be
+overridden with `make V=0'.
+
+Particular systems
+==================
+
+ On HP-UX, the default C compiler is not ANSI C compatible. If GNU
+CC is not installed, it is recommended to use the following options in
+order to use an ANSI C compiler:
+
+ ./configure CC="cc -Ae -D_XOPEN_SOURCE=500"
+
+and if that doesn't work, install pre-built binaries of GCC for HP-UX.
+
+ On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot
+parse its `<wchar.h>' header file. The option `-nodtk' can be used as
+a workaround. If GNU CC is not installed, it is therefore recommended
+to try
+
+ ./configure CC="cc"
+
+and if that doesn't work, try
+
+ ./configure CC="cc -nodtk"
+
+ On Solaris, don't put `/usr/ucb' early in your `PATH'. This
+directory contains several dysfunctional programs; working variants of
+these programs are available in `/usr/bin'. So, if you need `/usr/ucb'
+in your `PATH', put it _after_ `/usr/bin'.
+
+ On Haiku, software installed for all users goes in `/boot/common',
+not `/usr/local'. It is recommended to use the following options:
+
+ ./configure --prefix=/boot/common
+
+Specifying the System Type
+==========================
+
+ There may be some features `configure' cannot figure out
+automatically, but needs to determine by the type of machine the package
+will run on. Usually, assuming the package is built to be run on the
+_same_ architectures, `configure' can figure that out, but if it prints
+a message saying it cannot guess the machine type, give it the
+`--build=TYPE' option. TYPE can either be a short name for the system
+type, such as `sun4', or a canonical name which has the form:
+
+ CPU-COMPANY-SYSTEM
+
+where SYSTEM can have one of these forms:
+
+ OS
+ KERNEL-OS
+
+ See the file `config.sub' for the possible values of each field. If
+`config.sub' isn't included in this package, then this package doesn't
+need to know the machine type.
+
+ If you are _building_ compiler tools for cross-compiling, you should
+use the option `--target=TYPE' to select the type of system they will
+produce code for.
+
+ If you want to _use_ a cross compiler, that generates code for a
+platform different from the build platform, you should specify the
+"host" platform (i.e., that on which the generated programs will
+eventually be run) with `--host=TYPE'.
+
+Sharing Defaults
+================
+
+ If you want to set default values for `configure' scripts to share,
+you can create a site shell script called `config.site' that gives
+default values for variables like `CC', `cache_file', and `prefix'.
+`configure' looks for `PREFIX/share/config.site' if it exists, then
+`PREFIX/etc/config.site' if it exists. Or, you can set the
+`CONFIG_SITE' environment variable to the location of the site script.
+A warning: not all `configure' scripts look for a site script.
+
+Defining Variables
+==================
+
+ Variables not defined in a site shell script can be set in the
+environment passed to `configure'. However, some packages may run
+configure again during the build, and the customized values of these
+variables may be lost. In order to avoid this problem, you should set
+them in the `configure' command line, using `VAR=value'. For example:
+
+ ./configure CC=/usr/local2/bin/gcc
+
+causes the specified `gcc' to be used as the C compiler (unless it is
+overridden in the site shell script).
+
+Unfortunately, this technique does not work for `CONFIG_SHELL' due to
+an Autoconf bug. Until the bug is fixed you can use this workaround:
+
+ CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash
+
+`configure' Invocation
+======================
+
+ `configure' recognizes the following options to control how it
+operates.
+
+`--help'
+`-h'
+ Print a summary of all of the options to `configure', and exit.
+
+`--help=short'
+`--help=recursive'
+ Print a summary of the options unique to this package's
+ `configure', and exit. The `short' variant lists options used
+ only in the top level, while the `recursive' variant lists options
+ also present in any nested packages.
+
+`--version'
+`-V'
+ Print the version of Autoconf used to generate the `configure'
+ script, and exit.
+
+`--cache-file=FILE'
+ Enable the cache: use and save the results of the tests in FILE,
+ traditionally `config.cache'. FILE defaults to `/dev/null' to
+ disable caching.
+
+`--config-cache'
+`-C'
+ Alias for `--cache-file=config.cache'.
+
+`--quiet'
+`--silent'
+`-q'
+ Do not print messages saying which checks are being made. To
+ suppress all normal output, redirect it to `/dev/null' (any error
+ messages will still be shown).
+
+`--srcdir=DIR'
+ Look for the package's source code in directory DIR. Usually
+ `configure' can determine that directory automatically.
+
+`--prefix=DIR'
+ Use DIR as the installation prefix. *note Installation Names::
+ for more details, including other options available for fine-tuning
+ the installation locations.
+
+`--no-create'
+`-n'
+ Run the configure checks, but stop before creating any output
+ files.
+
+`configure' also accepts some other, not widely useful, options. Run
+`configure --help' for more details.

+open-vcdiff is an encoder and decoder for the VCDIFF format, as described in
+RFC 3284 : The VCDIFF Generic Differencing and Compression Data Format
+(http://www.ietf.org/rfc/rfc3284.txt)
+A library with a simple API is included, as well as a command-line executable
+that can apply the encoder and decoder to source, target, and delta files.
+For further details, please refer to:
+http://code.google.com/p/open-vcdiff/wiki/HowToUseOpenVcdiff
+
+See INSTALL for (generic) installation instructions for C++: basically
+ ./configure && make && make install
+
+This should compile the unit tests as well as "vcdiff", a simple command-line
+utility to run the encoder and decoder. Typical usage of vcdiff is as follows
+(the "<" and ">" are file redirect operations, not optional arguments):
+ vcdiff encode -dictionary file.dict < target_file > delta_file
+ vcdiff decode -dictionary file.dict < delta_file > target_file
+To see the command-line syntax of vcdiff, use "vcdiff --help" or just "vcdiff".
+
+To call the encoder from C++ code, assuming that dictionary, target, and delta
+are all std::string objects:
+#include <google/vcencoder.h> // Read this file for interface details
+[...]
+ open_vcdiff::VCDiffEncoder encoder(dictionary.data(), dictionary.size());
+ encoder.SetFormatFlags(open_vcdiff::VCD_FORMAT_INTERLEAVED);
+ encoder.Encode(target.data(), target.size(), &delta);
+
+Calling the decoder is just as simple:
+#include <google/vcdecoder.h> // Read this file for interface details
+[...]
+ open_vcdiff::VCDiffDecoder decoder;
+ decoder.Decode(dictionary.data(), dictionary.size(), delta, &target);
+
+When using the encoder, the C++ application must be linked with the library
+options -lvcdcom and -lvcdenc; when using the decoder, it must be linked with
+-lvcdcom and -lvcddec.
+
+To verify that the package works on your system, especially after making
+modifications to the source code, please run the unit tests using
+ make check

+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
+# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory. The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run. This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+# fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+# fails if $ac_aux_dir is absolute,
+# fails when called from a subdirectory in a VPATH build with
+# a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir. In an in-source build this is usually
+# harmless because $srcdir is `.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
+# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+# MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.
+#
+# Another solution, used here, is to always expand $ac_aux_dir to an
+# absolute PATH. The drawback is that using absolute paths prevent a

+\`configure' configures open-vcdiff 0.8.3 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE. See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+ -h, --help display this help and exit
+ --help=short display options specific to this package
+ --help=recursive display the short help of all the included packages
+ -V, --version display version information and exit
+ -q, --quiet, --silent do not print \`checking...' messages
+ --cache-file=FILE cache test results in FILE [disabled]
+ -C, --config-cache alias for \`--cache-file=config.cache'
+ -n, --no-create do not create output files
+ --srcdir=DIR find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+ --prefix=PREFIX install architecture-independent files in PREFIX
+ [$ac_default_prefix]
+ --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
+ [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.

+ --enable-static[=PKGS] build static libraries [default=yes]
+ --enable-fast-install[=PKGS]
+ optimize for fast installation [default=yes]
+ --disable-libtool-lock avoid locking (might break parallel builds)
+ --enable-namespace=FOO to define these Google
+ classes in the FOO namespace. --disable-namespace
+ to define them in the global namespace. Default
+ is to define them in namespace google.
+
+Optional Packages:
+ --with-PACKAGE[=ARG] use PACKAGE [ARG=yes]
+ --without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no)
+ --with-pic try to use only PIC/non-PIC objects [default=use
+ both]
+ --with-gnu-ld assume the C compiler uses GNU ld [default=no]
+
+Some influential environment variables:
+ CC C compiler command
+ CFLAGS C compiler flags
+ LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
+ nonstandard directory <lib dir>
+ LIBS libraries to pass to the linker, e.g. -l<library>
+ CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
+ you have headers in a nonstandard directory <include dir>
+ CPP C preprocessor
+ CXX C++ compiler command
+ CXXFLAGS C++ compiler flags
+ CXXCPP C++ preprocessor
+
+Use these variables to override the choices made by `configure' or to help
+it to find libraries and programs with nonstandard names/locations.

+# exported API, or moved to Autoconf or Automake where they belong.
+#
+# The trouble is, aclocal is a bit thick. It'll see the old AC_DEFUN

+# using a macro with the same name in our local m4/libtool.m4 it'll
+# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
+# and doesn't know about Autoconf macros at all.)

+# included after everything else. This provides aclocal with the
+# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
+# because those macros already exist, or will be overwritten later.
+# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6.
+#
+# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.

+.SH NAME
+vcdiff \- encoder/decoder for VCDIFF (RFC 3284) format
+.SH DESCRIPTION
+.HP
+\fBvcdiff\fR {\fBencode\fR|\fBdelta\fR|\fBdecode\fR|\fBpatch\fR}
+\fB\-dictionary\fR <filename>
+[<options>]
+.HP
+\fBencode\fR or \fBdelta\fR:
+create delta file from dictionary and target file
+.HP
+\fBdecode\fR or \fBpatch\fR:
+reconstruct target file from dictionary and delta file
+.HP
+\fB\-dictionary\fR <filename>
+.br
+File containing dictionary data (also known as source data.)
+Required for all operations.
+.HP
+\fB\-target\fR <filename>
+.br
+File name of the target file (unencoded data).
+The default value (blank) causes vcdiff to use standard input for encode,
+or standard output for decode.
+.HP
+\fB\-delta\fR <filename>
+.br
+File name of the delta file (encoded data).
+The default value (blank) causes vcdiff to use standard output for encode,
+or standard input for decode.
+.HP
+\fB\-checksum\fR
+.br
+Include an Adler32 checksum of the target data when encoding.
+Default is false.
+.HP
+\fB\-interleaved\fR
+.br
+Use interleaved format. Default is false.
+.HP
+\fB\-stats\fR
+.br
+Write a report to stderr, containing the original target size,
+compressed delta size, and compression percentage.
+Default is false.
+.HP
+\fB\-target_matches\fR
+.br
+Find duplicate strings in target data as well as dictionary data.
+Default is false.
+.HP
+\fB\-buffersize\fR <integer>
+.br
+The memory buffer size (in bytes) used for reading the input file.
+Default is 1048576 (1 MB); if the input file is smaller than that,
+the buffer will match the file size. This parameter does not usually
+need to be specified.

+ The 'zlib' compression library provides in-memory compression and
+ decompression functions, including integrity checks of the uncompressed
+ data. This version of the library supports only one compression method
+ (deflation) but other algorithms will be added later and will have the same
+ stream interface.
+
+ Compression can be done in a single step if the buffers are large
+ enough (for example if an input file is mmap'ed), or can be done by
+ repeated calls of the compression function. In the latter case, the
+ application must provide more input and/or consume the output
+ (providing more output space) before each call.
+
+ The compressed data format used by default by the in-memory functions is
+ the zlib format, which is a zlib wrapper documented in RFC 1950, wrapped
+ around a deflate stream, which is itself documented in RFC 1951.
+
+ The library also supports reading and writing files in gzip (.gz) format
+ with an interface similar to that of stdio using the functions that start
+ with "gz". The gzip format is different from the zlib format. gzip is a
+ gzip wrapper, documented in RFC 1952, wrapped around a deflate stream.
+
+ This library can optionally read and write gzip streams in memory as well.
+
+ The zlib format was designed to be compact and fast for use in memory
+ and on communications channels. The gzip format was designed for single-
+ file compression on file systems, has a larger header than zlib to maintain
+ directory information, and uses a different, slower check method than zlib.
+
+ The library does not install any signal handler. The decoder checks
+ the consistency of the compressed data, so the library should never
+ crash even in case of corrupted input.

+ deflate compresses as much data as possible, and stops when the input
+ buffer becomes empty or the output buffer becomes full. It may introduce some
+ output latency (reading input without producing any output) except when
+ forced to flush.
+
+ The detailed semantics are as follows. deflate performs one or both of the
+ following actions:
+
+ - Compress more input starting at next_in and update next_in and avail_in
+ accordingly. If not all input can be processed (because there is not
+ enough room in the output buffer), next_in and avail_in are updated and
+ processing will resume at this point for the next call of deflate().
+
+ - Provide more output starting at next_out and update next_out and avail_out
+ accordingly. This action is forced if the parameter flush is non zero.
+ Forcing flush frequently degrades the compression ratio, so this parameter
+ should be set only when necessary (in interactive applications).
+ Some output may be provided even if flush is not set.
+
+ Before the call of deflate(), the application should ensure that at least
+ one of the actions is possible, by providing more input and/or consuming
+ more output, and updating avail_in or avail_out accordingly; avail_out
+ should never be zero before the call. The application can consume the
+ compressed output when it wants, for example when the output buffer is full
+ (avail_out == 0), or after each call of deflate(). If deflate returns Z_OK
+ and with zero avail_out, it must be called again after making room in the
+ output buffer because there might be more output pending.
+
+ Normally the parameter flush is set to Z_NO_FLUSH, which allows deflate to
+ decide how much data to accumualte before producing output, in order to
+ maximize compression.
+
+ If the parameter flush is set to Z_SYNC_FLUSH, all pending output is
+ flushed to the output buffer and the output is aligned on a byte boundary, so
+ that the decompressor can get all input data available so far. (In particular
+ avail_in is zero after the call if enough output space has been provided
+ before the call.) Flushing may degrade compression for some compression
+ algorithms and so it should be used only when necessary.
+
+ If flush is set to Z_FULL_FLUSH, all output is flushed as with
+ Z_SYNC_FLUSH, and the compression state is reset so that decompression can
+ restart from this point if previous compressed data has been damaged or if
+ random access is desired. Using Z_FULL_FLUSH too often can seriously degrade
+ compression.
+
+ If deflate returns with avail_out == 0, this function must be called again
+ with the same value of the flush parameter and more output space (updated
+ avail_out), until the flush is complete (deflate returns with non-zero
+ avail_out). In the case of a Z_FULL_FLUSH or Z_SYNC_FLUSH, make sure that
+ avail_out is greater than six to avoid repeated flush markers due to
+ avail_out == 0 on return.
+
+ If the parameter flush is set to Z_FINISH, pending input is processed,
+ pending output is flushed and deflate returns with Z_STREAM_END if there
+ was enough output space; if deflate returns with Z_OK, this function must be
+ called again with Z_FINISH and more output space (updated avail_out) but no
+ more input data, until it returns with Z_STREAM_END or an error. After
+ deflate has returned Z_STREAM_END, the only possible operations on the
+ stream are deflateReset or deflateEnd.
+
+ Z_FINISH can be used immediately after deflateInit if all the compression
+ is to be done in a single step. In this case, avail_out must be at least
+ the value returned by deflateBound (see below). If deflate does not return
+ Z_STREAM_END, then it must be called again as described above.
+
+ deflate() sets strm->adler to the adler32 checksum of all input read
+ so far (that is, total_in bytes).
+
+ deflate() may update strm->data_type if it can make a good guess about
+ the input data type (Z_BINARY or Z_TEXT). In doubt, the data is considered
+ binary. This field is only for information purposes and does not affect
+ the compression algorithm in any manner.
+
+ deflate() returns Z_OK if some progress has been made (more input
+ processed or more output produced), Z_STREAM_END if all input has been
+ consumed and all output has been produced (only when flush is set to
+ Z_FINISH), Z_STREAM_ERROR if the stream state was inconsistent (for example
+ if next_in or next_out was NULL), Z_BUF_ERROR if no progress is possible
+ (for example avail_in or avail_out was zero). Note that Z_BUF_ERROR is not

+ inflate decompresses as much data as possible, and stops when the input
+ buffer becomes empty or the output buffer becomes full. It may introduce
+ some output latency (reading input without producing any output) except when
+ forced to flush.
+
+ The detailed semantics are as follows. inflate performs one or both of the
+ following actions:
+
+ - Decompress more input starting at next_in and update next_in and avail_in
+ accordingly. If not all input can be processed (because there is not
+ enough room in the output buffer), next_in is updated and processing
+ will resume at this point for the next call of inflate().
+
+ - Provide more output starting at next_out and update next_out and avail_out
+ accordingly. inflate() provides as much output as possible, until there
+ is no more input data or no more space in the output buffer (see below
+ about the flush parameter).
+
+ Before the call of inflate(), the application should ensure that at least
+ one of the actions is possible, by providing more input and/or consuming
+ more output, and updating the next_* and avail_* values accordingly.
+ The application can consume the uncompressed output when it wants, for
+ example when the output buffer is full (avail_out == 0), or after each
+ call of inflate(). If inflate returns Z_OK and with zero avail_out, it
+ must be called again after making room in the output buffer because there
+ might be more output pending.
+
+ The flush parameter of inflate() can be Z_NO_FLUSH, Z_SYNC_FLUSH,
+ Z_FINISH, or Z_BLOCK. Z_SYNC_FLUSH requests that inflate() flush as much
+ output as possible to the output buffer. Z_BLOCK requests that inflate() stop
+ if and when it gets to the next deflate block boundary. When decoding the
+ zlib or gzip format, this will cause inflate() to return immediately after
+ the header and before the first block. When doing a raw inflate, inflate()
+ will go ahead and process the first block, and will return when it gets to
+ the end of that block, or when it runs out of data.
+
+ The Z_BLOCK option assists in appending to or combining deflate streams.
+ Also to assist in this, on return inflate() will set strm->data_type to the
+ number of unused bits in the last byte taken from strm->next_in, plus 64
+ if inflate() is currently decoding the last block in the deflate stream,
+ plus 128 if inflate() returned immediately after decoding an end-of-block
+ code or decoding the complete header up to just before the first byte of the
+ deflate stream. The end-of-block will not be indicated until all of the
+ uncompressed data from that block has been written to strm->next_out. The
+ number of unused bits may in general be greater than seven, except when
+ bit 7 of data_type is set, in which case the number of unused bits will be
+ less than eight.
+
+ inflate() should normally be called until it returns Z_STREAM_END or an
+ error. However if all decompression is to be performed in a single step
+ (a single call of inflate), the parameter flush should be set to
+ Z_FINISH. In this case all pending input is processed and all pending
+ output is flushed; avail_out must be large enough to hold all the
+ uncompressed data. (The size of the uncompressed data may have been saved
+ by the compressor for this purpose.) The next operation on this stream must
+ be inflateEnd to deallocate the decompression state. The use of Z_FINISH
+ is never required, but can be used to inform inflate that a faster approach
+ may be used for the single inflate() call.
+
+ In this implementation, inflate() always flushes as much output as
+ possible to the output buffer, and always uses the faster approach on the
+ first call. So the only effect of the flush parameter in this implementation
+ is on the return value of inflate(), as noted below, or when it returns early
+ because Z_BLOCK is used.
+
+ If a preset dictionary is needed after this call (see inflateSetDictionary
+ below), inflate sets strm->adler to the adler32 checksum of the dictionary
+ chosen by the compressor and returns Z_NEED_DICT; otherwise it sets
+ strm->adler to the adler32 checksum of all output produced so far (that is,
+ total_out bytes) and returns Z_OK, Z_STREAM_END or an error code as described
+ below. At the end of the stream, inflate() checks that its computed adler32
+ checksum is equal to that saved by the compressor and returns Z_STREAM_END
+ only if the checksum is correct.
+
+ inflate() will decompress and check either zlib-wrapped or gzip-wrapped
+ deflate data. The header type is detected automatically. Any information
+ contained in the gzip header is not retained, so applications that need that
+ information should instead use raw inflate, see inflateInit2() below, or
+ inflateBack() and perform their own processing of the gzip header and
+ trailer.
+
+ inflate() returns Z_OK if some progress has been made (more input processed
+ or more output produced), Z_STREAM_END if the end of the compressed data has
+ been reached and all uncompressed output has been produced, Z_NEED_DICT if a
+ preset dictionary is needed at this point, Z_DATA_ERROR if the input data was
+ corrupted (input stream not conforming to the zlib format or incorrect check
+ value), Z_STREAM_ERROR if the stream structure was inconsistent (for example
+ if next_in or next_out was NULL), Z_MEM_ERROR if there was not enough memory,
+ Z_BUF_ERROR if no progress is possible or if there was not enough room in the
+ output buffer when Z_FINISH is used. Note that Z_BUF_ERROR is not fatal, and
+ inflate() can be called again with more input and more output space to
+ continue decompressing. If Z_DATA_ERROR is returned, the application may then

+ZEXTERN int ZEXPORT deflateInit2 OF((z_streamp strm,
+ int level,
+ int method,
+ int windowBits,
+ int memLevel,
+ int strategy));
+
+ This is another version of deflateInit with more compression options. The
+ fields next_in, zalloc, zfree and opaque must be initialized before by
+ the caller.
+
+ The method parameter is the compression method. It must be Z_DEFLATED in
+ this version of the library.
+
+ The windowBits parameter is the base two logarithm of the window size
+ (the size of the history buffer). It should be in the range 8..15 for this
+ version of the library. Larger values of this parameter result in better
+ compression at the expense of memory usage. The default value is 15 if
+ deflateInit is used instead.
+
+ windowBits can also be -8..-15 for raw deflate. In this case, -windowBits
+ determines the window size. deflate() will then generate raw deflate data
+ with no zlib header or trailer, and will not compute an adler32 check value.
+
+ windowBits can also be greater than 15 for optional gzip encoding. Add
+ 16 to windowBits to write a simple gzip header and trailer around the
+ compressed data instead of a zlib wrapper. The gzip header will have no
+ file name, no extra data, no comment, no modification time (set to zero),
+ no header crc, and the operating system will be set to 255 (unknown). If a
+ gzip stream is being written, strm->adler is a crc32 instead of an adler32.
+
+ The memLevel parameter specifies how much memory should be allocated
+ for the internal compression state. memLevel=1 uses minimum memory but
+ is slow and reduces compression ratio; memLevel=9 uses maximum memory
+ for optimal speed. The default value is 8. See zconf.h for total memory
+ usage as a function of windowBits and memLevel.
+
+ The strategy parameter is used to tune the compression algorithm. Use the
+ value Z_DEFAULT_STRATEGY for normal data, Z_FILTERED for data produced by a
+ filter (or predictor), Z_HUFFMAN_ONLY to force Huffman encoding only (no
+ string match), or Z_RLE to limit match distances to one (run-length
+ encoding). Filtered data consists mostly of small values with a somewhat
+ random distribution. In this case, the compression algorithm is tuned to
+ compress them better. The effect of Z_FILTERED is to force more Huffman
+ coding and less string matching; it is somewhat intermediate between
+ Z_DEFAULT and Z_HUFFMAN_ONLY. Z_RLE is designed to be almost as fast as
+ Z_HUFFMAN_ONLY, but give better compression for PNG image data. The strategy
+ parameter only affects the compression ratio but not the correctness of the
+ compressed output even if it is not set appropriately. Z_FIXED prevents the
+ use of dynamic Huffman codes, allowing for a simpler decoder for special
+ applications.
+
+ deflateInit2 returns Z_OK if success, Z_MEM_ERROR if there was not enough

+ Initializes the compression dictionary from the given byte sequence

+ dictionary (see inflateSetDictionary).
+
+ The dictionary should consist of strings (byte sequences) that are likely
+ to be encountered later in the data to be compressed, with the most commonly
+ used strings preferably put towards the end of the dictionary. Using a
+ dictionary is most useful when the data to be compressed is short and can be
+ predicted with good accuracy; the data can then be compressed better than
+ with the default empty dictionary.
+
+ Depending on the size of the compression data structures selected by
+ deflateInit or deflateInit2, a part of the dictionary may in effect be
+ discarded, for example if the dictionary is larger than the window size in
+ deflate or deflate2. Thus the strings most likely to be useful should be
+ put at the end of the dictionary, not at the front. In addition, the
+ current implementation of deflate will use at most the window size minus
+ 262 bytes of the provided dictionary.
+
+ Upon return of this function, strm->adler is set to the adler32 value
+ of the dictionary; the decompressor may later use this value to determine
+ which dictionary has been used by the compressor. (The adler32 value
+ applies to the whole dictionary even if only a subset of the dictionary is
+ actually used by the compressor.) If a raw deflate was requested, then the
+ adler32 value is not computed and strm->adler is not set.

+ function trusts the application to not change the output buffer passed by
+ the output function, at least until inflateBack() returns.
+
+ inflateBackInit() must be called first to allocate the internal state
+ and to initialize the state with the user-provided window buffer.
+ inflateBack() may then be used multiple times to inflate a complete, raw
+ deflate stream with each call. inflateBackEnd() is then called to free
+ the allocated state.
+
+ A raw deflate stream is one with no zlib or gzip header or trailer.
+ This routine would normally be used in a utility that reads zip or gzip
+ files and writes out uncompressed files. The utility would decode the

+ only the raw deflate stream to decompress. This is different from the
+ normal behavior of inflate(), which expects either a zlib or gzip header and
+ trailer around the deflate stream.
+
+ inflateBack() uses two subroutines supplied by the caller that are then
+ called by inflateBack() for input and output. inflateBack() calls those
+ routines until it reads a complete deflate stream and writes out all of the
+ uncompressed data, or until it encounters an error. The function's
+ parameters and return types are defined above in the in_func and out_func
+ typedefs. inflateBack() will call in(in_desc, &buf) which should return the
+ number of bytes of provided input, and a pointer to that input in buf. If
+ there is no input available, in() must return zero--buf is ignored in that
+ case--and inflateBack() will return a buffer error. inflateBack() will call
+ out(out_desc, buf, len) to write the uncompressed data buf[0..len-1]. out()
+ should return zero on success, or non-zero on failure. If out() returns
+ non-zero, inflateBack() will return with an error. Neither in() nor out()
+ are permitted to change the contents of the window provided to
+ inflateBackInit(), which is also the buffer that out() uses to write from.
+ The length written by out() will be at most the window size. Any non-zero
+ amount of input may be provided by in().
+
+ For convenience, inflateBack() can be provided input on the first call by
+ setting strm->next_in and strm->avail_in. If that input is exhausted, then
+ in() will be called. Therefore strm->next_in must be initialized before
+ calling inflateBack(). If strm->next_in is Z_NULL, then in() will be called
+ immediately for input. If strm->next_in is not Z_NULL, then strm->avail_in
+ must also be initialized, and then if strm->avail_in is not zero, input will
+ initially be taken from strm->next_in[0 .. strm->avail_in - 1].
+
+ The in_desc and out_desc parameters of inflateBack() is passed as the
+ first parameter of in() and out() respectively when they are called. These
+ descriptors can be optionally used to pass any information that the caller-
+ supplied in() and out() functions need to do their job.
+
+ On return, inflateBack() will set strm->next_in and strm->avail_in to

+ error in the deflate stream (in which case strm->msg is set to indicate the

+ distinguished using strm->next_in which will be Z_NULL only if in() returned
+ an error. If strm->next is not Z_NULL, then the Z_BUF_ERROR was due to
+ out() returning non-zero. (in() will always be called before out(), so
