LRZIP Changelog

What's new in LRZIP 0.616

Sep 10, 2013
  • Making things more homogeneous in checks, some space removed.
  • Simplifying and refactoring logic, alignment edits, empty semantic rewire.
  • Target directories must always exist and -f should not create them.
  • Deferring output directory after -f check has taken place.
  • Preserve extraction semantics without resorting to tar stripping.
  • Making sure last forward slash is removed from input path.
  • Removing pointless forced overwrite point check.

New in LRZIP 0.615 (Sep 5, 2013)

  • 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.
