b5e57b04	2023-05-06T16:41:13	[cid] Improve tracing messages; formatting.
be15811c	2023-05-03T01:31:37	[t1cid] Improve cid_get_cid_from_glyph_index(). Update cid_get_cid_from_glyph_index() to return an error and CID=0 in the case that the specified glyph index points to an invalid entry. cidgload.h (cid_compute_fd_and_offsets): Declare new helper function to set the fd_select and 2 offsets to access the glyph description data. cidgload.c (cid_compute_fd_and_offsets): Move the part loading fd_select and 2 offsets from cid_load_glyph() to here. If the loaded parameters are broken, return the Invalid_Offset error. This function does not load the glyph data, only fills these parameters. (cid_load_glyph): Use new helper function in above. cidriver.c (cid_get_cid_from_glyph_index): Check whether the requested glyph index points to a valid entry, by calling cid_compute_fd_and_offsets(). If it is valid, fill the cid by the glyph index (=CID). If it is invalid, return an error and fill the cid by 0.
4908c1e8	2023-04-28T06:54:25	* src/cid/cidgload.c (cid_load_glyph): Fix compiler warnings.
f312b340	2023-04-22T02:11:21	[t1cid] Change the trace messages of the charstrings retrieval errors. The t1cid driver catches 3 types of errors in the charstrings retrieval; A) The invalid FD number, there are 2 subtypes; A-1) FD number is the maximum number fitting to FDBytes. A-2) FD number is greater than num_dicts. B) Declared length is overrunning. C) Declared length is invalid (its end is before its head). Considering that some widely distributed fonts (e.g., "CJKV" book by O'Reilly) have A-1 errors in the unimplemented glyphs, the trace level for A-1 is calmed to level 1. The errors A-2, B, and C would be irregular; their trace levels are kept at level 0, but the updated trace messages include the CID number.
5ac6276a	2023-03-03T17:21:10	[cff,cid,type1] Shorten de-referencing. * src/cff/cffobjs.c (cff_clot_init): Use immediate library reference. * src/cid/cidobjs.c (cid_slot_init): Ditto. * src/type1/t1objs.c (T1_GlyphSlot_Init): Ditto.
09b326fa	2023-03-01T12:19:17	Avoid strtol on non-null-terminated data. Technically, `strtol` can only be used with C strings terminated with `\0`. CID data is not generally null-terminated and often does not contain a `\0` if it is hex-encoded. AddressSanitizer with `ASAN_OPTIONS` containing `strict_string_checks=1` verifies this by using an adversarial `strtol` that always reads to the terminating `\0`. To avoid undefined behavior from `strtol` in `cid_parser_new`, use the parser to parse the tokens instead of attempting to parse them ad-hoc. This will internally use `PS_Conv_Strtol` to parse the integer, which respects the parser's limits and directly implements the PostScript parsing rules for integers. * src/cid/cidparse.c (cid_parser_new): Use the parser to parse the tokens. Fixes: https://bugs.chromium.org/p/chromium/issues/detail?id=1420329

82fd32d6	2021-05-03T13:49:14	* src/cid/cidload.c (cid_hex_to_binary): Improve return value. Add argument to return the actual number of bytes that were decoded. The actual number of bytes decoded can be quite variable depending on the number of ignored 'whitespace' bytes or early termination with `>`. (cid_face_open): Updated to use this calculated value. This avoids trusting `parser->binary_length` is always be correct and reading uninitialized bits if fewer are actually decoded. First reported as https://crbug.com/1203240
d911cb53	2021-05-01T23:49:11	* src/cid/cidload.c (cid_read_subrs): Tweak allocaton macro.

d924a66a	2021-02-04T07:44:06	* src/*: Don't use more than one '\n' in `FT_TRACE` and `FT_ERROR`. This ensures good logging output, with all lines having a proper prefix (if requested). This is a continuation of a similar patch from 2020-12-02, which missed some locations.
b6e8a712	2021-01-17T07:18:48	Update all copyright notices.
a6adb256	2020-12-02T14:15:07	* src/*: Don't use more than one '\n' in `FT_TRACE` and `FT_ERROR`. This ensures good logging output, with all lines having a proper prefix (if requested).
5abd252a	2020-11-20T15:24:42	[cff,cid,type1] Demote old engine for lack of CFF2. * src/cff/cffobjs.c (cff_iriver_init): Always default to Adobe engine. * src/cid/cidobjs.c (cid_driver_init): Ditto. * src/type1/t1objs.c (T1_Driver_Init): Ditto.

8ed5a247	2020-06-19T10:35:57	[cff, cid] Fix segfaults in case of error (#58621). * src/cff/cffobjs.c (cff_slot_done), src/cid/cidobjs.c (cid_slot_done): If `ft_glyphslot_init' fails to allocate `internal', then the class' `done_slot' callback (called by `ft_glyphslot_done') must not dereference the pointer to `internal'.
16586859	2020-06-13T21:15:45	Remove redundant inclusion of `ft2build.h'. * /: Remove `#include <ft2build.h>' where possible. * include/freetype/freetype.h: Remove cpp error about missing inclusion of `ft2build.h'.
e1339133	2020-06-08T13:31:55	Make macros for header file names optional. We no longer have to take care of the 8.3 file name limit; this allows us (a) to introduce longer, meaningful file names, and (b) to avoid macro names in `#include' lines altogether since some compilers (most notably Visual C++) doesn't support this properly. /: Replace #include FOO_H with #include <freetype/foo.h> or something similar. Also update the documentation.
4eee1340	2020-05-18T09:16:12	Remove Jamfile files from the tree. These have not been used in a very, very long time, so better remove them. A corresponding patch will be submitted to the `freetype2-demos' repository. * src/Jamfile, src/*/Jamfile, Jamrules: Delete.
e5038be7	2020-01-19T17:05:19	Update all copyright notices.

2f4b740c	2019-03-07T09:42:25	Fix invalid function pointer casts. This change should allow Freetype to work on WASM/Emscripten without needing `-s EMULATE_FUNCTION_POINTER_CASTS=1'. * src/autofit/afdummy.c (af_dummy_hints_apply): Fix signature. * src/cid/cidload.c (cid_parse_font_matrix, parse_fd_array, parse_expansion_factor, parse_font_name): Return `void', not `FT_Error'. * include/freetype/internal/ftobjs.h (FT_CMap_CharVarIsDefaultFunc): Fix signature.

f686ad46	2019-01-22T20:31:44	Update copyright years.
a9af6914	2018-09-25T09:10:09	Fix handing of `FT_Bool'. Before this commit we had code like (FT_Bool)( globals->glyph_styles[gindex] & 0x8000) Since `FT_Bool' is defined to be an `unsigned char', the code evaluated to something like (unsigned char)( 0x8532 & 0x8000) which in turn expanded to (unsigned char)( 0x8000) and finally yielded 0x00 – i.e., false – not as expected. Problem reported and analyzed by Tony Smith <tony.smith@macro4.com>. * include/freetype/fttypes.h (FT_BOOL): Add a comparison against zero so that we always have a Boolean expression. /: Replace castings to `FT_Bool' with calls to `FT_BOOL' where possible.
a0dd16fb	2018-08-15T18:13:17	Don't use `trace_' prefix for FT_COMPONENT arguments. * include/freetype/internal/ftdebug.h (FT_TRACE_COMP, FT_TRACE_COMP_): New auxiliary macros to add `trace_' prefix. (FT_TRACE): Use `FT_TRACE_COMP'. / (FT_COMPONENT): Updated.

8e57746c	2018-07-31T10:46:57	[cid] Trace PostScript dictionaries. * src/cid/cidload.c: Include FT_INTERNAL_POSTSCRIPT_AUX_H (cid_load_keyword, cid_parse_font_matrix, parse_fd_array, parse_expansion_factor, cid_parse_dict): Add tracing calls. (parse_font_name): New function to trace `/FontName' keywords in /FDArray dict. (cid_field_records): Register `parse_font_name'.
a5acdce1	2018-07-22T12:11:52	[cid] Sanitize `BlueShift' and `BlueFuzz'. This code is taken from the type1 module. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=9510 * src/cid/cidload.c (parse_fd_array): Set some private dict default values. (cid_face_open): Do the sanitizing. Fix some tracing messages.

9ac9060d	2018-06-03T09:01:17	[GSoC] src/.: Convert block comments to `light' style. This monster commit was created by applying Nikhil's scripts `docconverter.py' and `markify.py' to all C header and source files, followed up by minor manual clean-up. No change in functionality, of course. I used commit f7419907bc6044b9b7057f9789866426c804ba82 from https://github.com/nikramakrishnan/freetype-docs.git.
95149592	2018-05-02T20:27:48	Remove FT_CONFIG_OPTION_PIC and related code. / [FT_CONFIG_OPTION_PIC]: Remove all code guarded by this preprocessor symbol. /: Replace `XXX_GET' macros (which could be either a function in PIC mode or an array in non-PIC mode) with `xxx' arrays. * include/freetype/internal/ftpic.h, src/autofit/afpic.c, src/autofit/afpic.h, src/base/basepic.c, src/base/basepic.h, src/base/ftpic.c, src/cff/cffpic.c, src/cff/cffpic.h, src/pshinter/pshpic.c, src/pshinter/pshpic.h, src/psnames/pspic.c, src/psnames/pspic.h, src/raster/rastpic.c, src/raster/rastpic.h, src/sfnt/sfntpic.c, src/sfnt/sfntpic.h, src/smooth/ftspic.c, src/smooth/ftspic.h, src/truetype/ttpic.c, src/truetype/ttpic.h: Removed.

[t1cid] Improve cid_get_cid_from_glyph_index(). Update cid_get_cid_from_glyph_index() to return an error and CID=0 in the case that the specified glyph index points to an invalid entry. cidgload.h (cid_compute_fd_and_offsets): Declare new helper function to set the fd_select and 2 offsets to access the glyph description data. cidgload.c (cid_compute_fd_and_offsets): Move the part loading fd_select and 2 offsets from cid_load_glyph() to here. If the loaded parameters are broken, return the Invalid_Offset error. This function does not load the glyph data, only fills these parameters. (cid_load_glyph): Use new helper function in above. cidriver.c (cid_get_cid_from_glyph_index): Check whether the requested glyph index points to a valid entry, by calling cid_compute_fd_and_offsets(). If it is valid, fill the cid by the glyph index (=CID). If it is invalid, return an error and fill the cid by 0.

[t1cid] Change the trace messages of the charstrings retrieval errors. The t1cid driver catches 3 types of errors in the charstrings retrieval; A) The invalid FD number, there are 2 subtypes; A-1) FD number is the maximum number fitting to FDBytes. A-2) FD number is greater than num_dicts. B) Declared length is overrunning. C) Declared length is invalid (its end is before its head). Considering that some widely distributed fonts (e.g., "CJKV" book by O'Reilly) have A-1 errors in the unimplemented glyphs, the trace level for A-1 is calmed to level 1. The errors A-2, B, and C would be irregular; their trace levels are kept at level 0, but the updated trace messages include the CID number.

Avoid strtol on non-null-terminated data. Technically, `strtol` can only be used with C strings terminated with `\0`. CID data is not generally null-terminated and often does not contain a `\0` if it is hex-encoded. AddressSanitizer with `ASAN_OPTIONS` containing `strict_string_checks=1` verifies this by using an adversarial `strtol` that always reads to the terminating `\0`. To avoid undefined behavior from `strtol` in `cid_parser_new`, use the parser to parse the tokens instead of attempting to parse them ad-hoc. This will internally use `PS_Conv_Strtol` to parse the integer, which respects the parser's limits and directly implements the PostScript parsing rules for integers. * src/cid/cidparse.c (cid_parser_new): Use the parser to parse the tokens. Fixes: https://bugs.chromium.org/p/chromium/issues/detail?id=1420329

Make macros for header file names optional. We no longer have to take care of the 8.3 file name limit; this allows us (a) to introduce longer, meaningful file names, and (b) to avoid macro names in `#include' lines altogether since some compilers (most notably Visual C++) doesn't support this properly. */*: Replace #include FOO_H with #include <freetype/foo.h> or something similar. Also update the documentation.

Fix handing of `FT_Bool'. Before this commit we had code like (FT_Bool)( globals->glyph_styles[gindex] & 0x8000) Since `FT_Bool' is defined to be an `unsigned char', the code evaluated to something like (unsigned char)( 0x8532 & 0x8000) which in turn expanded to (unsigned char)( 0x8000) and finally yielded 0x00 – i.e., false – not as expected. Problem reported and analyzed by Tony Smith <tony.smith@macro4.com>. * include/freetype/fttypes.h (FT_BOOL): Add a comparison against zero so that we always have a Boolean expression. */*: Replace castings to `FT_Bool' with calls to `FT_BOOL' where possible.

Make Jam support work again. This is just very basic stuff and just a little bit tested on GNU/Linux only. I won't delve into this since I'm not a Jam user. * Jamfile: Call `HDRMACRO' for `ftserv.h' also. (DEFINES): Replace with... (CCFLAGS): ... this. * src/Jamfile: Don't call `HDRMACRO' for `internal.h'; this is already handled in the top-level Jamfile. * src/autofit/Jamfile (DEFINES): Replace with... (CCFLAGS): ... this. (_sources): Add missing files. * src/cache/Jamfile: Don't call `HDRMACRO' for `ftcache.h'; it no longer contains macro header definitions. * src/base/Jamfile, src/cff/Jamfile, src/sfnt/Jamfile, src/truetype/Jamfile (_sources): Add missing files.
