Known bugs and suggested enhancements in libpng-1.0.8
|

|
||||
1. July 2, 2000 -- BUG -- pnggccrd.c
|
||||
|
||||
Some programs compiled with PNG_USE_PNGGCCRD crash in pnggccrd.c.
|
||||
Also, pnggccrd.c will not compile under gcc-2.95-2.
|
||||
|
||||
STATUS: Under investigation. Experts on MMX assembler code are
|
||||
invited to help with the debugging. Note that pngvcrd.c works fine.
|
||||
|
||||
Update: fixed in libpng-1.0.8beta1. It compiles under gcc-2.7.2.3
|
||||
and seems to work; under gcc-2.7.2.1 it compiles but crashes in
|
||||
execution. It is recommended that people use 2.95.2 or later.
|
||||
|
||||
The png_read_filter() function has still not been fully converted and
|
||||
will not compile under gcc-2.95.2; it is currently ifdef'ed out.
|
||||
|
||||
2. July 3, 2000 -- BUG -- MEMORY LEAK
|
||||
STATUS: Under investigation. Experts on MMX assembler code are
|
||||
invited to help with the debugging. Note that pngvcrd.c works fine.
|
||||
|
||||
There is a memory leak in pngpread.c; it doesn't free "key".
|
||||
|
||||
STATUS: Fixed in libpng-1.0.8beta1, by adding.

png_free(png_ptr, text_ptr);
|
||||

||||
after lines 1221 and 1038 in pngpread.c

3. July 3, 2000 -- BUG -- PNG_EXPORT_VAR
|
||||
|
||||
The definition of PNG_EXPORT_VAR, in pngconf.h, should be
|
||||
# define PNG_EXPORT_VAR(type) extern PNG_IMPEXP type
|
||||
|
||||
STATUS: Fixed in libpng-1.0.8beta1.
|
||||
|
||||
4. July 3, 2000 -- BUG -- PNG_NO_STDIO
|
||||
|
||||
Several places in pngrutil.c and pngwutil.c, there are printf statements
|
||||
inside PNG_NO_STDIO blocks (should be PNG_NO_CONSOLE_IO)
|
||||
|
||||
STATUS: Fixed in libpng-1.0.8beta1.
|
||||

5. July 3, 2000 -- ENHANCEMENT -- WindowsCE support
|
||||
|
||||
Libpng-1.0.7 does not support WindowsCE.
|
||||
|
||||
STATUS: Libpng-1.0.8 and libpng-2.0.0 will support WindowsCE. A
|
||||
new typedef, png_FILE_p, will be added which is normally FILE * but
|
||||
will be HANDLE if libpng is being built for WindowsCE. Other patches
|

required for WindowsCE support have been provided and will be applied.

Finished in libpng-1.0.8beta3.
