lrzip ChangeLog
SEPTEMBER 2013, version 0.615 Con Kolivas, George Makrydakis
* Adjusting -O flag semantics, options help update.
* Making -O flag operative for lrztar, whitespace path fix, lrzuntar fix, other
minor.
* Further tighten up ram restrictions with stdin/stdout to prevent running out
of memory with all the buffers involved.
* Massive files fail with -U due to trying to allocate the whole lot in ram
while doing checksums. Do it piecemeal to avoid the problem. Patch and debugging
courtesy of Adam Tkáč.
* We have to run through the clear buffer function even for empty buffers or
corrupt archives with empty match streams.
* MD5 code uses little endian so remove arbitrary SWAP macro and explicitly use
htole32.
* Rewrite the magic if we receive lzma properties and have not yet written them
yet during stdout operation.
* Set the control lzma properties only once.
* Add a control lock mutex for protecting certain control variables.
* Fix stdin fake mremap creating null bytes on osx, patch courtesy of John
Boyle.
* Cache frequently used indirectly referenced variables in the sliding mmap
code.
* Micro-optimise sliding_get_sb_range.
* A fix for a bug where large files containing the same non-zero bytes which
requires a sliding window, courtesy of Serge Belyshev.
* Put vchar should take a 64 bit integer and is used from more than one call
site so uninline it.
* Microoptimise in hash_search.
* Inline rzip functions used from only one caller.
* Check for successful calloc of hash table only after performing it.
* stdin_eof is just a bool
* hash_bits can only be up to 64 so use a char type.
* Check endianness of build with autotools to enable md5 support on more
platforms.
JULY 2012, version 0.614 Con Kolivas
* Fix lrztar failing due to incorrect fix for -S freeing segfault.
