- Update to 5.2.5:
* liblzma:
- Fixed several C99/C11 conformance bugs. Now the code is clean
under gcc/clang -fsanitize=undefined. Some of these changes
might have a negative effect on performance with old GCC
versions or compilers other than GCC and Clang. The configure
option --enable-unsafe-type-punning can be used to (mostly)
restore the old behavior but it shouldn't normally be used.
- Improved API documentation of lzma_properties_decode().
- Added a very minor encoder speed optimization.
* xz:
- Fixed a crash in "xz -dcfv not_an_xz_file". All four options
were required to trigger it. The crash occurred in the
progress indicator code when xz was in passthru mode where
xz works like "cat".
- Fixed an integer overflow with 32-bit off_t. It could happen
when decompressing a file that has a long run of zero bytes
which xz would try to write as a sparse file. Since the build
system enables large file support by default, off_t is
normally 64-bit even on 32-bit systems.
- Fixes for --flush-timeout:
* Fix semi-busy-waiting.
* Avoid unneeded flushes when no new input has arrived
since the previous flush was completed.
- Added a special case for 32-bit xz: If --memlimit-compress is
used to specify a limit that exceeds 4020 MiB, the limit will
be set to 4020 MiB. The values "0" and "max" aren't affected
by this and neither is decompression. This hack can be
helpful when a 32-bit xz has access to 4 GiB address space
but the specified memlimit exceeds 4 GiB. This can happen
e.g. with some scripts.
- Capsicum sandbox is now enabled by default where available
(FreeBSD >= 10). The sandbox debug messages (xz -vv) were
removed since they seemed to be more annoying than useful.
