67890a19f3 [libpng17] Committed pngvalid.c omitted from previous commit; fix trivial typos 2015-03-22 21:01:48 -05:00

53097f5bbb [libpng17] Check (png_uint_16) casts for overflow. Also removed png_muldiv_warn,
added RELEASE/!RELEASE convenience macros. png_muldiv_warn was used in
only one place, and the overflow condition is a genuine warning not
an internal error.  Four macros allow code or function parameters to be
condition on RELEASE (or not) builds and tidy up the #ifdef handling of
functions.

36562c1032 [libpng17] Improved some overflow handling. PNG_RELEASE_BUILD replaces tests
where the code depended on the build base type and can be defined on
the command line, allowing testing in beta builds.  Overflows previously
handled by png_warning in png.c have been changed to use new
macros/affirm functions so that beta builds will abort on overflow and
release builds will quietly ignore it.  This avoids release builds
producing warnings that are of no use to end users.

82fa6aed0e [libpng17] Added byte, short and other overflow checking
Added 'assert' based overflow checking for debug builds for char
and short assignments. Simply ignore the error in release builds
(a truncated value will be used without warning). Controlled by
PNG_RANGE_CHECK_SUPPORTED.
