f34f1925 | 2014-11-26 21:59:21 | * src/*: Add checks for parameters of API functions where missing. `API functions' are functions tagged with `FT_EXPORT_DEF'. Besides trivial fixes, the following changes are included, too. * src/base/ftbdf.c (FT_Get_BDF_Charset_ID, FT_Get_BDF_Property): Set error code if no service is available. * src/base/ftinit.c (FT_Done_FreeType): Change return value for invalid `library' parameter to `Invalid_Library_Handle'. * src/base/ftobjs.c (FT_New_Size): Change return value for invalid `asize' parameter to `Invalid_Argument'. * src/base/ftoutln.c (FT_Outline_Copy): Change return value for invalid `source' and `target' parameters to `Invalid_Outline'. (FT_Outline_Done_Internal): Change return value for invalid `outline' parameter to `Invalid_Outline'. | |

dc624ca4 | 2013-06-04 10:30:48 | Apply fixes for cppcheck nitpicks. http://cppcheck.sourceforge.net/ Note that the current version heavily chokes on FreeType, delivering even wrong results. I will report those issues to the cppcheck team so that a newer version gives improved results hopefully. */* Improve variable scopes. */* Remove redundant initializations which get overwritten. * src/base/ftmac.c ,builds/mac/ftmac.c (count_faces_scalable): Remove unused variable. * src/base/ftdbgmem.c (ft_mem_table_destroy): `table' can't be zero. * src/gxvalid/gxvkern.c (gxv_kern_subtable_fmt1_entry_validate): Remove functionless code. * src/tools/ftrandom.c (main): Fix memory leak. | |
|
e3c93015 | 2013-03-14 11:21:17 | */*: Use FT_Err_Ok only. This is a purely mechanical conversion. | |
|
059bc335 | 2013-03-14 10:27:35 | */*: Use `FT_THROW'. This is essentially a mechanical conversion, adding inclusion of `FT_INTERNAL_DEBUG_H' where necessary, and providing the macros for stand-alone compiling modes of the rasterizer modules. To convert the remaining occurrences of FT_Err_XXX and friends it is necessary to rewrite the code. Note, however, that it doesn't harm if some cases are not handled since FT_THROW is a no-op. | |
 |
26dfeb6d | 2012-03-08 06:04:03 | Prepare source code for amalgamation. * src\autofit\aferrors.h, src\bdf\bdferror.h, src\bzip2\ftbzip2.c, src\cache\ftcerror.h, src\cff\cfferrs.h, src\cid\ciderrs.h, src\gxvalid\gxverror.h, src\gzip\ftgzip.c, src\lzw\ftlzw.c, src\otvalid\otverror.h, src\pcf\pcferror.h, src\pfr\pfrerror.h, src\psaux\psauxerr.h, src\pshinter\pshnterr.h, src\psnames\psnamerr.h, src\raster\rasterrs.h, src\sfnt\sferrors.h, src\smooth\ftsmerrs.h, src\truetype\tterrors.h, src\type1\t1errors.h, src\type42\t42error.h, src\winfonts\fnterrs.h: Add #undef FT_ERR_PREFIX before #define FT_ERR_PREFIX. | |
 |
1749d8bc | 2012-01-17 02:00:24 | Remove trailing spaces. | |
 |
487913d9 | 2011-09-11 09:18:10 | Slightly improve LZW_CLEAR handling. * src/lzw/ftzopen.c (ft_lzwstate_io) <FT_LZW_PHASE_CODE>: Ensure that subsequent (modulo garbage byte(s)) LZW_CLEAR codes are handled as clear codes. This also re-sets old_code and old_char to predictable values, which is a little better than using `random' ones if the code following LZW_CLEAR is invalid. | |
|
83cb6c00 | 2011-09-11 09:13:45 | Add explicit LZW decompression stack size limit. Stack larger than 1<<LZW_MAX_BITS is never needed if prefix table is constructed correctly. It's even less than that, see e.g. libarchive code comment for a better size upper bound: http://code.google.com/p/libarchive/source/browse/trunk/libarchive/archive_read_support_filter_compress.c?r=3635#121 This patch adds explicit stack size limit, enforced when stack is realloced. An alternative is to ensure that code < state->prefix[code - 256] when traversing prefix table. Such check is less efficient and should not be required if prefix table is constructed correctly in the first place. * src/lzw/ftzopen.c (ft_lzwstate_stack_grow): Implement it. | |
|
86c3c69c | 2011-09-11 09:08:40 | Protect against loops in the prefix table. LZW decompressor did not sufficiently check codes read from the input LZW stream. A specially-crafted or corrupted input could create a loop in the prefix table, which leads to memory usage spikes, as there's no decompression stack size limit. * src/lzw/ftzopen.c (ft_lzwstate_io) <FT_LZW_PHASE_START>: First code in valid LZW stream must be 0..255. <FT_LZW_PHASE_CODE>: In the special KwKwK case, code == free_ent, code > free_ent is invalid. | |
|
e62c876b | 2011-06-15 02:48:33 | Fix g++4.6 compiler warnings in module drivers. The background is same with previous commit. * src/truetype/ttgxvar.c (ft_var_readpackedpoints): Init `points'. (TT_Vary_Get_Glyph_Deltas): Init `delta_xy'. (TT_Get_MM_Var): Init `mmvar'. * src/type1/t1load.c (T1_Get_MM_Var): Ditto. * src/cff/cffdrivr.c (cff_ps_get_font_info): Init `font_info'. * src/cff/cffload.c (cff_index_get_pointers): Init `t'. (cff_font_load): Init `sub'. * src/cff/cffobjs.c (cff_size_init): Init `internal'. (cff_face_init): Init `cff'. * src/pfr/pfrload.c (pfr_extra_item_load_stem_snaps): Init `snaps'. * src/pcf/pcfread.c (pcf_get_properties): Init `properties'. (pcf_get_bitmaps): Init `offsets'. (pcf_get_encodings): Init `tmpEncoding'. * src/sfnt/ttload.c (tt_face_load_gasp): Init `gaspranges'. * src/sfnt/ttsbit.c (Load_SBit_Image): Init `components'. * src/cache/ftcmru.c (FTC_MruList_New): Init `node'. * src/gzip/ftgzip.c (FT_Stream_OpenGzip): Init `zip' and `zip_buff'. * src/lzw/ftlzw.c (FT_Stream_OpenLZW): Init `zip'. * src/bzip2/ftbzip2.c (FT_Stream_OpenBzip2): Init `zip'. | |
|
f765e440 | 2010-06-24 10:34:29 | */*: Use module specific error names where appropriate. | |
|
fc58155a | 2010-01-05 20:00:35 | Apply reports from clang static analyzer. * src/lzw/ftlzw.c (ft_lzw_file_init), src/base/ftstroke.c (FT_Stroker_ParseOutline), src/base/ftsynth.c (FT_GlyphSlot_Embolden): Remove dead code. * src/base/ftpatent.c (_tt_check_patents_in_table): Initialize `offset_i'. | |

1dcd0f23 | 2009-04-05 18:25:14 | Add #error to modules and files that do not support PIC yet. When FT_CONFIG_OPTION_PIC is defined the following files will create #error: * src/bdf/bdfdrivr.h * src/cache/ftcmanag.c * src/cid/cidriver.h * src/gxvalid/gxvmod.h * src/gzip/ftgzip.c * src/lzw/ftlzw.c * src/otvalid/otvmod.h * src/pcf/pcfdrivr.h * src/pfr/pfrdrivr.h * src/psaux/psauxmod.h * src/type1/t1driver.h * src/type42/t42drivr.h * src/winfonts/winfnt.h | |

68df4f73 | 2005-03-15 18:18:57 | * src/bdf/bdflib.c: various improvements to the bdf loader, mainly used to reduce the amount of heap size required to only test wether we're dealing with a BDF font (the old code allocated 64 Kb right before any test). * src/lzw/ftlzw.c (FT_Stream_OpenLZW): modified the function to check the LZW header before doing anything else. This helps avoid un-necessary heap allocations (400 Kb of heap memory for the LZW decoder ! Oh my !) * src/gzip/ftgzip.c (FT_Stream_OpenGZip): ditto for the .gz decoder, though the code savings is smaller. | |
|
f9b44e30 | 2004-06-15 13:57:00 | * src/lzw/zopen.c: Comment out inclusion of `signal.h' and `unistd.h'. | |
|
10bf05a3 | 2004-04-21 14:30:37 | * src/cff/cffobjs.c (cff_face_init): fixed a small memory leak * src/autofit/afloader.c, src/autofit/afmodule.c, src/base/ftdebug.c: removed compiler warnings * src/autofit/aftypes.h, src/lzw/zopen.c, src/pcf/pcfdrivr.c, src/pcf/pcfread.c, src/psaux/psobjs.c, src/type42/t42drivr.c: changed data arrays to "const" to avoid populating the ".data" segment | |
 |
497cc7c4 | 2004-04-12 18:09:00 | Jamfile to bring in the new lzw module. My first try at this exercise, please report problems, I lack experience! Antoine | |
|
161438c5 | 2004-04-12 15:31:30 | * src/lzw/zopen.c: Don't include sys/param.h and sys/stat.h. | |
|
391de1a6 | 2004-04-11 16:44:54 | * src/lzw/ftlzw.c: Include zopen.h dependent on FT_CONFIG_OPTION_USE_LZW. * src/base/ftdebug.c: s/index/idx/ to avoid compiler warnings. | |
