Changes since the last public release (1.6.14):
|
||||
Changed "if (!x)" to "if (x == 0)" and "if (x)" to "if (x != 0)"
|
||||
Simplified png_free_data().
|
||||
Added missing "ptr = NULL" after some instances of png_free().
|
||||
Made a one-line revision to configure.ac to support ARM on aarch64
|
||||
(bug report by Marcin Juszkiewicz, fix by John Bowler).
|
||||
Avoid out-of-bounds memory access in png_user_version_check().
|
||||
Simplified and future-proofed png_user_version_check().
|
||||
Fixed GCC unsigned int->float warnings. Various versions of GCC
|
||||
seem to generate warnings when an unsigned value is implicitly
|
||||
converted to double. This is probably a GCC bug but this change
|
||||
avoids the issue by explicitly converting to (int) where safe.
|
||||
Free all allocated memory in pngimage. The file buffer cache was left
|
||||
allocated at the end of the program, harmless but it causes memory
|
||||
leak reports from clang.
|
||||
Fixed array size calculations to avoid warnings. At various points
|
||||
in the code the number of elements in an array is calculated using
|
||||
sizeof. This generates a compile time constant of type (size_t) which
|
||||
is then typically assigned to an (unsigned int) or (int). Some versions
|
||||
of GCC on 64-bit systems warn about the apparent narrowing, even though
|
||||
the same compiler does apparently generate the correct, in-range,
|
||||
numeric constant. This adds appropriate, safe, casts to make the
|
||||
warnings go away.
|
||||
Removed #ifdef PNG_16BIT_SUPPORTED/#endif around png_product2(); it is
|
||||
needed by png_reciprocal2().
|
||||
Added #ifdef PNG_16BIT_SUPPORTED/#endif around png_log16bit() and
|
||||
png_do_swap().
|
||||
Changed all "#endif /* PNG_FEATURE_SUPPORTED */" to "#endif /* FEATURE */"
|
||||
The macros passed in the command line to Borland make were ignored if
|
||||
similarly-named macros were already defined in makefiles. This behavior
|
||||
is different from POSIX make and other make programs. Surround the
|
||||
macro definitions with ifndef guards (Cosmin).
|
||||
Added "-D_CRT_SECURE_NO_WARNINGS" to CFLAGS in scripts/makefile.vcwin32.
|
||||
Removed the obsolete $ARCH variable from scripts/makefile.darwin.
|
||||
Changes since the last public release (1.6.15):
|
||||
Added ".align 2" to arm/filter_neon.S to support old GAS assemblers that
|
||||
don't do alignment correctly.
|
||||
Revised Makefile.am and scripts/*.dfn to work with MinGW/MSYS;
|
||||
renamed scripts/*.dfn to scripts/*.c (Bob Friesenhahn and John Bowler).
|
||||
Quiet a "comparison always true" warning in pngstest.c (John Bowler).
|
||||
Restored a test on width that was removed from png.c at libpng-1.6.9
|
||||
(Bug report by Alex Eubanks).
|
||||
Fixed an overflow in png_combine_row with very wide interlaced images.
