| |
| Apply Savannah patch #7422. |
| |
| If we encounter a space in a string then the sbit buffer is NULL, |
| height and width are 0s. So the check in ftc_snode_compare will |
| always pass for spaces (comparision with 255). Here the comments |
| above the condition are proper but the implementation is not. When |
| we create an snode I think it is the proper way to initialize the |
| width to 255 and then put a check for being equal to 255 in snode |
| compare function. |
| |
| * src/cache/ftcsbits.c (FTC_SNode_New): Initialize sbit widths with |
| value 255. |
| (ftc_snode_compare): Fix condition. |

| |
| [cache] Change the hash types to FT_PtrDist. |
| |
| On LLP64 platforms (e.g. Win64), FT_ULong (32-bit) |
| variables are inappropriate to calculate hash values |
| from the memory address (64-bit). The hash variables |
| are extended from FT_ULong to FT_PtrDist and new |
| hashing macro functions are introduced. The hash |
| values on 16-bit memory platforms are changed, but |
| ILP32 and LP64 are not changed. The hash value in |
| the cache subsystem is not reverted to the memory |
| address, so using signed type FT_PtrDist is safe. |
| |
| * src/cache/ftccache.h (_FTC_FACE_ID_HASH): New hash |
| function to replace FTC_FACE_ID_HASH() for portability. |
| * src/cache/ftcmanag.h (FTC_SCALER_HASH): Replace |

| [cache] Hide internal macros incompatible with LLP64. |
| |
| FT_POINTER_TO_ULONG(), FTC_FACE_ID_HASH() and |

| Change the type of FT_MEM_VAL() from FT_ULong to FT_PtrDist. |
| |
| On LLP64 platforms (e.g. Win64), unsigned long (32-bit) |
| cannot cover the memory address (64-bit). FT_MEM_VAL() is |
| used for hashing only and not dereferred, so using signed |
| type FT_PtrDist is safe. |
| |
| * src/base/ftdbgmem.c (FT_MEM_VAL): Change the type of the |

| Replace "%lx" for memory address by "%p", LLP64 platforms. |
| |
| On LLP64 platforms (e.g. Win64), long (32-bit) cannot cover |
| the memory address (64-bit). Also the casts from the pointer |
| type to long int should be removed to preserve the address |
| correctly. |
| |
| * src/raster/ftraster.c (New_Profile): Replace "%lx" by "%p". |

| [raccess] Skip unrequired resource access rules by Darwin VFS. |
| |
| When a resource fork access rule by Darwin VFS could open the |
| resource fork but no font is found in it, the rest of rules |
| by Darwin VFS are skipped. It reduces the warnings of the |
| deprecated resource fork access method by recent Darwin kernel. |
| Fix MacPorts ticket #18859: |
| http://trac.macports.org/ticket/18859 |
| |
| * src/base/ftobjs.c (load_face_in_embedded_rfork): |
| When FT_Stream_New() returns FT_Err_Cannot_Open_Stream, it |
| means that the file is possible to be fopen()-ed but zero-sized. |
| Also there is a case that the resource fork is not zero-sized, |
| but no supported font exists in it. If a rule by Darwin VFS |
| falls into such cases, there is no need to try other Darwin VFS |
| rules anymore. Such cases are marked by vfs_rfork_has_no_font. |
| If it is TRUE, the Darwin VFS rules are skipped. |
| |
| 2010-10-13 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> |
| |
| [raccess] Grouping resource access rules based on Darwin VFS. |
| |
| MacOS X/Darwin kernel supports a few tricky methods to access |
| a resource fork via ANSI C or POSIX interface. Current resource |
| fork accessor tries all possible methods to support all kernels. |
| But if a method could open a resource fork but no font is found, |
| there is no need to try other methods older than tested method. |
| To determine whether the rule index is for Darwin VFS, a local |
| function ftrfork.c::raccess_rule_by_darwin_vfs() is introduced. |
| To use this function in ftobjs.c etc but it should be inlined, |
| it is exposed by ftbase.h. |
| |
| * src/base/ftrfork.c (FT_RFork_Rule): New enum type to identify |
| the rules to access the resource fork. |
| (raccess_guess_rec): New structure to bind the rule function and |
| rule enum type. |
| (FT_Raccess_Guess): The list of the rule functions is replaced by |
| (raccess_guess_table): This. This is exposed to be used by other |
| intra module functions. |
| (raccess_rule_by_darwin_vfs): A function to return a boolean |
| if the rule specified by the rule index is based on Darwin VFS. |

| Prevent to open a FT_Stream for zero-sized file on non-Unix. |
| |
| builds/unix/ftsystem.c prevents to open an useless stream from |
| zero-sized file and returns FT_Err_Cannot_Open_Stream, but the |
| stream drivers for ANSI C, Amiga and VMS return useless streams. |
| For cross-platform consistency, all stream drivers should act |
| same. |
| |
| * src/base/ftsystem.c (FT_Stream_Open): If the size of the opened |
| file is zero, FT_Err_Cannot_Open_Stream is returned. |

| 2010-09-19 Werner Lemberg <wl@gnu.org> |
| |
| Minor fixes. |
| |
| * src/cff/cffload.c (cff_charset_compute_cids): `charset->sids[i]' |
| is `FT_UShort'. |
| (cff_index_access_element): Don't use additions in comparison. |
| * src/sfnt/ttpost.c (load_format_20): Make `post_limit' of type |
| `FT_Long'. |
| Don't use additions in comparison. |
| Improve tracing messages. |
| (load_format_25, load_post_names): Make `post_limit' of type |
| `FT_Long'. |
| |
| 2010-09-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> |
| |
| [cff] Truncate the element length at the end of the stream. |
| See Savannah bug #30975. |
| |
| * src/cff/cffload.c (cff_index_access_element): `off2', the offset |
| to the next element is truncated at the end of the stream to prevent |
| invalid I/O. As `off1', the offset to the requested element has |
| been checked by FT_STREAM_SEEK(), `off2' should be checked |
| similarly. |
| |
| 2010-09-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> |
| |
| [cff] Ignore CID > 0xFFFFU. |
| See Savannah bug #30975. |
| |
| * src/cff/cffload.c (cff_charset_compute_cids): Ignore CID if |
| greater than 0xFFFFU. CFF font spec does not mention maximum CID in |
| the font, but PostScript and PDF spec define that maximum CID is |
| 0xFFFFU. |
| |
| 2010-09-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> |
| |
| [cff] Make trace message in cff_charset_load() verbose. |
| See Savannah bug #30975. |
| |
| * src/cff/cffload.c (cff_charset_load): Report the original `nleft' |
| and truncated `nleft'. |
| |
| 2010-09-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> |
| |
| [cff] Correct `max_cid' from CID array length to max CID. |
| See Savannah bug #30975. |
| |
| * src/cff/cffload.c (cff_charset_compute_cids): Don't increment |
| max_cid after detecting max CID. The array CFF_Charset->cids is |
| allocated by max_cid + 1. |
| (cff_charset_cid_to_gindex): Permit CID is less than or equal to |
| CFF_Charset->max_cid. |
| * src/cff/cffobjs.c (cff_face_init): FT_Face->num_glyphs is |
| calculated as CFF_Charset->max_cid + 1. |
| |
| 2010-09-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> |
| |
| [truetype] Sanitize the broken offsets in `loca'. |
| See Savannah bug #31040. |
| |
| * src/truetype/ttpload.c (tt_face_get_location): If `pos1', the |
| offset to the requested entry in `glyf' exceeds the end of the |
| table, return offset=0, length=0. If `pos2', the offset to the next |
| entry in `glyf' exceeds the end of the table, truncate the entry |
| length at the end of `glyf' table. |
| |
| 2010-09-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> |
| |
| [sfnt] Prevent overrunning in `post' table parser. |
| See Savannah bug #31040. |
| |
| * src/sfnt/ttpost.c (load_post_names): Get the length of `post' |
| table and pass the limit of `post' table to load_format_20() and |
| load_format_25(). |
| (load_format_20): Stop the parsing when we reached at the limit of |
| `post' table. If more glyph names are required, they are filled by |
| NULL names. |
| |
| 2010-09-17 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> |
| |
| [truetype] Don't duplicate size->twilight structure to be freed. |
| See Savannah bug #31040 for detail. |
| |
| * src/truetype/ttinterp.c (free_buffer_in_size): Don't duplicate |
| FT_GlyphZoneRec size->twilight to be freed. If duplicated, |
| FT_FREE() erases the duplicated pointers only and leave original |
| pointers. They can cause the double-free crash when the burst |
| errors occur in TrueType interpreter and free_buffer_in_size() is |
| invoked repeatedly. |
| |
| 2010-09-15 Werner Lemberg <wl@gnu.org> |
| |
| Make bytecode debugging with FontForge work again. |
| |
| * src/truetype/ttinterp.c (TT_RunIns): Don't call |
| `free_buffer_in_size' in case of error if a debugger is active. |
| |
| 2010-09-14 Werner Lemberg <wl@gnu.org> |
| |
| Improve tracing messages. |
| |
| * src/truetype/ttinterp.c (TT_RunIns): Improve wording of tracing |
| message. |
| * src/truetype/ttobjs.c (tt_size_run_fpgm, tt_size_run_prep): Add |
| tracing message. |
| * src/truetype/ttgload.c (tt_loader_init): Add tracing message. |
| * src/cache/ftcsbits.c (ftc_snode_load): Emit tracing message if |
| glyph doesn't fit into a small bitmap container. |
| |
| 2010-09-13 Werner Lemberg <wl@gnu.org> |
| |
| Fix minor issues reported by <muktha.narayan@wipro.com>. |
| |
| * src/autofit/aflatin.c (af_latin_compute_stem_width): Remove |
| redundant conditional check. |
| * src/base/ftsynth.c (FT_GlyphSlot_Embolden): Ditto. |
| * src/cff/cffload.c (cff_encoding_load): Remove conditional check |
| which always evaluates to `true'. |
| * src/pshinter/pshalgo.c (ps_glyph_interpolate_strong_points): |
| Ditto. |
| * src/truetype/ttinterp.c (Ins_IUP): Ditto. |
| * src/cid/cidgload.c (cid_slot_load_glyph): Don't check for NULL if |
| value is already dereferenced. |
| * src/winfonts/winfnt.c (FNT_Load_Glyph): Fix check of `face'. |
| |
| 2010-08-31 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> |
| |
| Ignore the environmental setting of LIBTOOL. |
| Patch is suggested by Adrian Bunk, to prevent unexpected |
| reflection of environmental LIBTOOL. See: |
| http://savannah.nongnu.org/patch/?7290 |
| |
| * builds/unix/unix-cc.in: LIBTOOL is unconditionally set to |
| $(FT_LIBTOOL_DIR)/libtool. FT_LIBTOOL_DIR is set to $(BUILD_DIR) |
| by default. |
| * configure: When configured for the building out of source tee, |
| FT_LIBTOOL_DIR is set to $(OBJ_DIR). |
| |
| 2010-08-31 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> |
| |
| [truetype] Decrease the trace level catching the interpreter error. |
| |
| * src/truetype/ttinterp.c (TT_RunIns): Decrease the trace level |
| showing the error when the interpreter returns with an error, |
| from FT_TRACE7() to FT_TRACE1(). |
| |
| 2010-08-30 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> |
| |
| [truetype] Prevent bytecode reuse after the interpretation error. |
| |
| * src/truetype/ttinterp.c (free_buffer_in_size): New function to |
| free the buffer allocated during the interpretation of this glyph. |
| (TT_RunIns): Unset FT_Face->size->{cvt_ready,bytecode_ready} if |
| an error occurs in the bytecode interpretation. The interpretation |
| of invalid bytecode may break the function definitions and referring |
| them in later interpretation is danger. By unsetting these flags, |
| `fpgm' and `prep' tables are executed again in next interpretation. |
| |
| This fixes Savannah bug #30798, reported by Robert Święcki. |
| |
| 2010-08-29 Werner Lemberg <wl@gnu.org> |
| |
| [ftraster] Pacify compiler. |
| |
| * src/raster/ftraster.c (ft_black_new) [_STANDALONE_]: `memory' is |
| not used. |
| |
| 2010-08-29 Werner Lemberg <wl@gnu.org> |
| |
| [cff] Allow SIDs >= 65000. |
| |
| * src/cff/cffload.c (cff_charset_load): Fix change from 2009-03-20: |
| The threshold for SIDs is not applicable here. I misinterpreted the |
| `SID values 65000 and above are available for implementation use' |
| sentence in the CFF specification. |
| |
| Problem reported by Ivan Ninčić <inincic@pdftron.com>. |

| |
| Force hinting when the font lacks its familyname. |
| |
| In Type42 or Type11 font embedded in PostScript & PDF, TrueType sfnt |
| stream may lack `name' table because they are not required. Hinting |
| for nameless fonts is safer for PDFs including embedded Chinese |
| fonts. Written by David Bevan, see: |
| |
| http://lists.gnu.org/archive/html/freetype-devel/2010-08/msg00021.html |
| http://lists.freedesktop.org/archives/poppler/2010-August/006310.html |
| |
| * src/truetype/ttobjs.c (tt_check_trickyness): If a NULL pointer by |
| nameless font is given, TRUE is returned to enable hinting. |
| |
| 2010-08-28 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> |
| |
| Register yet another tricky TrueType font. |
| |
| * src/truetype/ttobjs.c (tt_check_trickyness): Add `HuaTianKaiTi?', |
| a Kaishu typeface paired with `HuaTianSongTi?' by Huatian |
| Information Industry. |

| 2010-05-10 Ken Sharp <ken.sharp@artifex.com> |
| |
| Fix Savannah bug #29846. |
| |
| Previously we discovered fonts which used `setcurrentpoint' to set |
| the initial point of a contour to 0,0. This caused FreeType to |
| raise an error, because the `setcurrentpoint' operator is only |
| supposed to be used with the results from an OtherSubr subroutine. |
| |
| This was fixed by simply ignoring the error and carrying on. |
| |
| Now we have found a font which uses setcurrentpoint to actually |
| establish a non-zero point for a contour during the course of a |
| glyph program. FWIW, these files may be produced by an application |
| called `Intaglio' on the Mac, when converting TrueType fonts to |
| Type 1. |
| |
| The fix allows the new invalid behaviour, the old invalid behaviour |
| and real proper usage of the operator to work the same way as Adobe |
| interpreters apparently do. |
| |
| (t1_decoder_parse_charstrings): Make `setcurrentpoint' use the top |
| two elements of the stack to establish unconditionally the current x |
| and y coordinates. |
| |
| Make the `flex' subroutine handling (OtherSubr 0) put the current |
| x,y coordinates onto the stack, instead of two dummy uninitialised |
| values. |
