- We don't want both active (since brute mode detects everything that intense mode detects), but they can have different recursion depth limits, so helper functions helps keeping things clean
- Progress of copying uncompressed bytes is shown
- Better bzip2 on-the-fly compression progress
- lzma on-the-fly compression: As this buffers internally and we do not know how much bytes will be written beforehand, it shows a seperate progress text (total/written/left lzma data in MiB)
- Use of std::string constructor instead of "\b\b\b..." strings
- No more "status strings" in DLL mode (e.g. "Precompressing: ")
- Time between progress updates set to 250 ms for both work sign and percentage
- Use at least the memory for LZMA preset 1
- Added methods for memory and thread defaults to avoid code duplication
- Fix: Precomp Comfort used invalid Compression_Method as default
- Fix: Use singular if only 1 thread is used
- Fix: precomp_dll.h had use_mp3 declared twice
- original compressed size is tracked now
- trying combination stop has a new constraint: new compressed size must
be the same as the original compressed size
- fixed some usages of identical_bytes_decomp (instead of
best_identical_bytes_decomp) that could lead to "No matches" although
matches were found
- Merged compare_file_mem and compare_files_penalty
- There was a temporary file between the two functions before which is
not needed anymore, comparisons are done in memory on 512 byte chunks
- Result on silesia.zip: 15% faster (30,7 s => 26,2 s)
- See issue #14
- Before, partial matches led to additional decompression and
recompression to determinate the precise size of the partial match
- We can remove these 2 steps by using a slightly less precise size that
is known before
- Results for silesia.zip: 20% faster (37->30 seconds), 0.2% overhead in
bZip2 compressed variant (64,629,217 -> 64,764,849 bytes)
- Moved contrib declarations from precomp.cpp in header files in contrib
directories
- Moved Precomp declarations to precomp.h
- Renamed old precomp.h to precomp_dll.h
