Con Kolivas 624de254ce Revert "Fallocate space in advance on decompression." 
This reverts commit cf03cb0c04.

Fallocating for some reason fails to write the end of the file! Revert change pending further investigation.

Con Kolivas cf03cb0c04 Fallocate space in advance on decompression. 
This often can speed up decompression of large files and decreases fragmentation.

ckolivas 9b60d6e703 Update manpage to new, cleaner help format. 2011-02-25 10:55:27 +11:00
ckolivas 930b86fabe Update manpage reflecting verbose information. 2011-02-25 10:32:33 +11:00
ckolivas e337cce320 Increment version to 0.570. 2011-02-25 10:16:58 +11:00
ckolivas f9f880908c Remove the slightly fragile exponential growth buffer size. 
It was only speeding up compression a small amount, yet adversely affected compression and would segfault due to the size not being consistent on successive passes.

Con Kolivas dcf62d11a0 Make sure not to make the bufsize larger than the limit. 
Drop the page rounding since it is of no demonstrable benefit but adds complexity.
 2011-02-24 12:20:06 +11:00
Con Kolivas 22ae326d01 Make it always clear that a failure to allocate a buffer has occurred on compression. 2011-02-24 11:52:30 +11:00
Con Kolivas 8bf60c3114 Don't round to page size if the entire buffer will fit, otherwise this generates one extra pass of a tiny chunk. 2011-02-24 11:38:31 +11:00
Con Kolivas a0ab78ba8d Update lrzip.conf parser to respect -U, -H, -T, k, and -c options. 
Further updates to documentation.

 2011-02-24 03:07:57 +11:00
Con Kolivas d90f670fbd The output from information is confusing on 32 bit when it cuts the available ram for internal use. 
Display the actual amount of ram detected, and then decrease the value for calculating what the calculated window will be.
Move the variables to where they're only used locally.
 2011-02-23 23:58:50 +11:00
Con Kolivas 402dbbed65 Make sure we don't start shrinking the buffer size. 2011-02-23 15:34:43 +11:00
Con Kolivas 48e7e31dad Make sure to not delete files that already exist and we've refused to overwrite! 2011-02-23 15:01:43 +11:00
Con Kolivas 9fef6ab803 Add verbose and max verbose modes for -i information. 
This will give a breakdown of each rzip chunk and compressed block by jumping to each head offset and reading the header information.

Con Kolivas 8edc4bd052 Trivial 2011-02-23 01:29:17 +11:00

Con Kolivas e79127ace8 Trivial changes. 2011-02-23 01:22:54 +11:00
Con Kolivas 94673d3fe3 Change the LZO testing option to be a bool on/off instead of taking a confusing parameter. 
Make the lzo testing message simpler and only appear when max verbose mode is enabled.

Con Kolivas fa34905d9d Update documentation. 2011-02-22 21:17:00 +11:00

Con Kolivas aa9056b461 Minor output fix to prevent %% showing when one thread changes from 100% to be replaced with 10%. 2011-02-22 20:39:13 +11:00
Con Kolivas 9c8b1ee795 Deprecate the -M option as it is no longer of any significant utility compared to the -U option. 2011-02-22 20:38:39 +11:00
Con Kolivas 0f1d447541 Update benchmarks. 2011-02-22 20:26:55 +11:00
Con Kolivas 011344753a With lzma and zpaq, the compression overhead per thread is significant. 
As we can work out what that compression overhead is, we can factor that into testing how much ram we can allocate.
There is no advantage to running multiple threads when there is no compression back end so drop to 1 only.
Limit ram for compression back end to 1/3 ram regardless for when OSs lie due to heavy overcommit.
 2011-02-22 15:19:31 +11:00
Con Kolivas bcb857d934 Don't add extra threads for single-threaded decompression case. 2011-02-22 00:58:55 +11:00
Con Kolivas bb33f7571c Multi-threading speed ups. 
Add one more thread on compression and decompression to account for the staggered nature of thread recruitment.
Make the initial buffer slightly smaller and make it progressively larger, thus recruiting threads sooner and more evenly.
This also speeds up decompression for the same reason.
Check the amount of memory being used by each thread on decompression to ensure we don't try to recruit too much ram.
