2021-12-24Fix deflateBound and compressBound returning very small size estimates.Hans Kristian Rosbach
Remove workaround in switchlevels.c, so we do actual testing of this. Use named defines instead of magic numbers where we can.

http://infozip.sourceforge.net/ is sadly not having HTTPS access enabled. Shoutout to somebody with admin access for this project: It would be nice to enable it and thus allowing secure access to these pages via https://infozip.sourceforge.io/ . The option has been there for a while now: https://sourceforge.net/blog/introducing-https-for-project-websites/ also: - follow permanent redirects - add ending slashes

deflate.c:589:49: warning: comparison between signed and unsigned integer expressions [-Wsign-compare]
2020-07-10Fixed ubsan error in deflatePrime when bits is 32.Nathan Moinvaziri
deflate.c:602:15: runtime error: shift exponent 32 is too large for 32-bit type 'int32_t' (aka 'int') SUMMARY: UndefinedBehaviorSanitizer: undefined-behavior /src/zlib-ng/deflate.c:602:15
2020-07-01Fixed bad shift operation warning in deflatePrime.Nathan Moinvaziri
Check that bits value is not greater than bits allowed by value type. CID 293475 (#2-4 of 4): Bad bit shift operation (BAD_SHIFT) In expression 1UL << put, left shifting by more than 63 bits has undefined behavior.

2020-06-08Fixed wrong 64-bit casting in deflatePrime potentially causing bits to be lost.Nathan Moinvaziri
Arithmetic overflow: Using operator '<<' on a 4 byte value and then casting the result to a 8 byte value. Cast the value to the wider type before calling operator '<<' to avoid overflow (io.2). Arithmetic overflow: 32-bit value is shifted, then cast to 64-bit value. Results might not be an expected value.
