lrzip ChangeLog
DECEMBER 2010, version 0.544 Con Kolivas
* Make multiple stream 0 entry decompression more robust by creating separate
thread groups for stream 0 and stream 1.
* uclibc fails to return valid values for memory size with sysconf so create
a workaround.
* 32 bits has memory allocation errors on large files so be ruthless with
limiting window sizes and use more sliding mmap.
* Split up compression streams according to proportion of hash search thus
evenly distributing work to threads based on raw data length rather than
rzip pre-processed data. This makes for more CPU usage on compression and
smoother write out on decompression with small speed ups.
* Remove unnecessary argument passing.
* Fix -U causing a floating point error with ultra small sized files.
* 32 bits still sometimes fails the lzma compression stage due to internal
memory allocation issues, so use bzip2 as a fallback on blocks that fail to
compress.
* Minor cleanups.
NOVEMBER 2010, version 0.543 Con Kolivas
* Fix for when there are multiple stream 0 entries per chunk, which would
cause a failure on decompression.
