| Changes since the last public release (1.5.26): |
| |
| version 1.5.27beta01 [March 9, 2016] |
| Removed LE/BE dependencies in pngvalid, to 'fix' the current problem |
| in the BigEndian tests by not testing it, making the BE code the same |
| as the LE version. |
| Fixes to pngvalid for various reduced build configurations (eliminate unused |
| statics) and a fix for the case in rgb_to_gray when the digitize option |
| reduces graylo to 0, producing a large error. |
| Widened the 'limit' check on the internally calculated error limits in |
| the 'DIGITIZE' case (the code used prior to 1.7 for rgb_to_gray error |
| checks) and changed the check to only operate in non-release builds |
| (base build type not RC or RELEASE.) |
| Fixed undefined behavior in pngvalid.c, undefined because |
| (png_byte) << shift is undefined if it changes the signed bit |
| (because png_byte is promoted to int). The libpng exported functions |
| png_get_uint_32 and png_get_uint_16 handle this. (Bug reported by |
| David Drysdale as a result of reports from UBSAN in clang 3.8). |
| This changes pngvalid to use BE random numbers; this used to produce |
| errors but these should not be fixed as a result of the previous changes. |
| In projects/vstudio, combined readme.txt and WARNING into README.txt |
| Worked around a false-positive Coverity issue in pngvalid.c. |
| Only use exit(77) from pngvalid.c in configure builds. |
| Updated CMakeLists.txt, added supporting scripts/gen*.cmake.in |
| and test.cmake.in (Roger Leigh). |
| Added a common-law trademark notice and export control information |
| to the LICENSE file, png.h, and the man page. |
| Changed PNG_INFO_cHNK and PNG_FREE_cHNK from 0xnnnn to 0xnnnnU in png.h |
| (Robert C. Seacord). |
| Fixed some misleading indentation in pngvalid.c (Krishnaraj Bhat). |
