e1339133 | 2020-06-08 13:31:55 | 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. | |

9ac9060d | 2018-06-03 09:01:17 | [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. | |

8521ad99 | 2016-08-16 13:44:38 | [lzw] Optimize last commit. * src/lzw/ftzopen.c (ft_lzwstate_get_code): Move check into conditional clause. | |

83d4181a | 2015-02-25 08:10:58 | [lzw] Signedness fixes. * src/lzw/ftzopen.c, src/lzw/ftzopen.h: Apply. | |

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. | |

c6afa122 | 2006-05-02 22:22:16 | * include/freetype/internal/ftmemory.h: s/new/newsz/ (for C++). (FT_ALLOC): Remove redundant redefinition. * builds/compiler/gcc-dev.mk (CFLAGS) [g++]: Don't use `-Wstrict-prototypes'. * src/base/ftstream.c (FT_Stream_EnterFrame): Add cast.
