2016-08-29 15:46:27 +00:00
Version 1.6.26beta01 [September 26, 2016]
2016-09-01 22:28:08 +00:00
Fixed handling zero length IDAT in pngfix (bug report by Agostino Sarubbo,
bugfix by John Bowler).
Do not issue a png_error() on read in png_set_pCAL() because png_handle_pCAL
has allocated memory that libpng needs to free.
Conditionally compile png_set_benign_errors() in pngread.c and pngtest.c
Issue a png_benign_error instead of a png_error on ADLER32 mismatch
while decoding compressed data chunks.
Changed PNG_ZLIB_VERNUM to ZLIB_VERNUM in pngpriv.h, pngstruct.h, and
pngrutil.c.
If CRC handling of critical chunks has been set to PNG_CRC_QUIET_USE,
ignore the ADLER32 checksum in the IDAT chunk as well as the chunk CRCs.
Issue png_benign_error() on ADLER32 checksum mismatch instead of png_error().
Add tests/badcrc.png and tests/badadler.png to tests/pngtest.
Merged pngtest.c with libpng-1.7.0beta84/pngtest.c
Version 1.6.26beta02 [October 1, 2016]
Updated the documentation about CRC and ADLER32 handling.
Quieted 117 warnings from clang-3.8 in pngtrans.c, pngread.c,
pngwrite.c, pngunknown.c, and pngvalid.c.
Quieted 116 (out of 288) -Wconversion compiler warnings by changing
flag definitions in pngpriv.h from 0xnnnn to 0xnnnnU and trivial changes
in png.c, pngread.c, and pngwutil.c.
