changes from 0.607: * a rare case of not being able to decompress archives was fixed * the lzma library was updated to version 920 * more debugging info was added in maximum verbose mode * fewer messages occur without verbose mode ------------------------------------------------------------------- Tue May 17 09:45:10 UTC 2011 - pascal.bleser@opensuse.org - update to 0.606: * lrzuntar broke as lrzip doesn't automatically use stdout now, so use lrzcat in the lrztar script instead ------------------------------------------------------------------- Sun May 8 14:04:40 UTC 2011 - pascal.bleser@opensuse.org - update to 0.605: * lrzcat was added, which automatically decompresses .lrz files to STDOUT * lrzip and lrunzip will no longer automatically output to STDOUT when output is redirected * progress output will no longer spam the output unless the percentage has changed * lrzip now has no lower limit on the file sizes it will happily compress and is able to work with zero byte sized files * the percentage counter when getting file information on small files will not show %nan * the executable bit will not be enabled when compressing via a means that can't preserve the original permissions (e.g. from STDIN) ------------------------------------------------------------------- Wed Apr 27 07:16:13 UTC 2011 - pascal.bleser@opensuse.org - update to 0.604: * lrzip will no longer fail with a "resource temporarily unavailable" error when compressing files over 100GB that require hundreds of threads to complete ------------------------------------------------------------------- Sun Apr 24 20:53:38 UTC 2011 - pascal.bleser@opensuse.org - update to 0.603: * detect when stdout is being redirected and automatically direct output to stdout unless a filename is specified * update lrztar to properly support -S -O and -o, and use new syntax not requiring '-o -' for stdout * update lrzip.conf to support encryption * do a sanity check to ensure lrzip is not attempting to work on a directory ------------------------------------------------------------------- Sun Apr 24 20:16:57 UTC 2011 - pascal.bleser@opensuse.org - update to 0.603: ------------------------------------------------------------------- Wed Apr 13 09:37:00 UTC 2011 - pascal.bleser@opensuse.org - update to 0.602: * limits were imposed for 32-bit machines with way too much RAM for their own good * full version is displayed with -V * fle permissions are better carried over instead of being only 0600 ------------------------------------------------------------------- Wed Mar 23 23:30:52 UTC 2011 - pascal.bleser@opensuse.org - update to 0.601: no user-visible changes ------------------------------------------------------------------- Wed Mar 23 09:29:45 UTC 2011 - pascal.bleser@opensuse.org - update to 0.600: * massive rewrite with new file format to accomodate new features * allocate temporary buffers of safely sized ram that can act as temporary storage for performing de/compression to/from STDIN/STDOUT without requiring temporary physical files; files compressed on machines with much larger ram being decompressed on smaller ram machines may still require temporary files, but as much as possible is done using in-ram decompression, and minimally sized temporary files; information displayed is more verbose and accurate in STDIN/STDOUT mode * the temporary buffers created for decompressing to STDOUT are also used for decompressing regular files now avoiding multiple write/reads when re-constructing the file on decompression: this can dramatically speed up the rzip phase of decompression on complicated files with many small matches, and always makes testing faster * compress block headers as well now since we know how many bytes can be used to describe the length of the block, decreasing overall file size * store the rzip chunk size per chunk to make it possible to check total file size by summating each rzip chunk size when it's not known till the end (as happens when compressing from STDIN) * implement password protected encryption: + import the polarssl code for sha512 and aes128 routines + read password without echoing to screen by disabling echo via terminfo + take the password then multiply hash it according to the date it was generated + increase the number of hashes according to Moore's law so it always takes approximately 1 second per password on the most modern hardware when first encrypted + hash the password against 8 bytes of salt which is a combination of the 2 byte encoded loop counter (for how many times to hash the password) and 6 random bytes + take random from /dev/urandom if it's available and fall back to random() if not + encrypt each block of compressed data with 8 extra bytes of random salt + once the headers are written, go back and encrypt the headers as well + then encrypt the md5 hash value as well + anything beyond the initial lrzip magic header should apppear as random data and no two successive encryptions of the same data with the same password should generate the same data + big Endian fixes + change lrztar and lrzuntar to not use temporary files + countless other fixes, documentation and cleanups ------------------------------------------------------------------- Tue Mar 08 10:38:13 UTC 2011 - pascal.bleser@opensuse.org - update to 0.571: * negative value allocs are now prevented with high thread/low RAM combinations * free space is now checked before attempting to compress or decompress, and the program aborts if there is inadequate space and -f is not enabled * the check for where data is going when refusing to write stdout to a terminal was corrected * temporary files are unlinked as soon as possible to minimize the chance of stale temporary files being left * file check can no longer be enabled when meaningless * the time displayed and progress when known from STDIN were fixed * spurious errors when trying to mmap files are avoided * temporary file sizes used when decompressing to STDOUT were minimized ------------------------------------------------------------------- Fri Feb 25 16:51:19 UTC 2011 - pascal.bleser@opensuse.org - update to 0.570: * improvements were made for more CPU usage and faster compression and decompression * memory is now precisely controlled to avoid running out of memory while using the largest possible compression windows * a single thread is used when advantageous * verbose output options were added for -i information * the lrzip.conf features were updated * the -M option was dropped * the -T lzo testing option was changed to not take a parameter * deletion of files that the program has refused to overwrite is prevented * output in failure modes was made cleaner * default compiler flags were added * the program now refuses to read from or write to a terminal with stdin/stdout * missed temporary files are deleted * a large clean up of the documentation was done ------------------------------------------------------------------- Mon Feb 21 19:12:05 UTC 2011 - pascal.bleser@opensuse.org - update to 0.560: * implement md5 hash checking on compression and decompression by using buffers to pass to the existing crc checking and re-using them for the md5 checking * speed up the hash checking on compression by not reading the whole chunk at once to do the hash check, and instead read one paged size chunk * store the md5 hash value at the end of the archive, maintaining backward compatibility with existing 0.5 versions of lrzip, and places a flag in the header denoting its existence * use the header flag for md5's existence to determine what hash check to perform on decompression * add hash value display to maximum verbose output and in information mode * add -H option to enable hash value displaying without verbose mode * display what hash checking will be used on decompression in verbose mode and in information displayed with -i * add -c option to perform a hash check on the file generated on decompression, comparing it to that stored in the lrzip archive, or that generated on decompression on archives that do not have it stored * delete broken or damaged files generated on interruption or when they fail integrity testing by default * implement the -k option to keep broken or damaged files ------------------------------------------------------------------- Fri Feb 11 12:05:13 UTC 2011 - pascal.bleser@opensuse.org - update to 0.552: * fix incompressible blocks causing failure with bzip2 and gzip * flush writes to disk before allocating ram * relax memory allocation when no back end compression will be used * clean up unnecessary semaphore usage in decompression * fix minor typos * convert mmaps to malloc in runzip as they may silently fail if not a multiple of page size, thereby leading to silent corruption on decompression * return the correct length by unzip_literal - changes from 0.551: * fix stdin failing due to getting sizes all wrong * fix stdin compression values not being shown at end * fix inappropriate failure when lzma doesn't compress block - changes from 0.550: * move the threading on compression to higher up in the code, allowing the next stream to start using compression threads before the previous stream has finished; this speeds up compression on files that take more than one pass to compress * limit the number of threads decompressing stream 0 to just 1 since it's always followed by stream 1 chunks, and it may lead to failure to decompress due to running out of memory by running too many threads * default compression level and window size on lzma is set to 7 which is the highest it goes; scale the 9 lrzip levels into 7, thus making the default lzma level 5 which uses a lot less memory and is substantially faster at the cost of some compression * rationalise the memory testing now that the default lzma settings use a lot less ram by default, and make all systems use no more than 1/3 ram in one mmap; this allows larger windows to be used by 32 bit at last without memory allocation errors * revert "Make threads spawn at regular intervals along chunk size thus speeding up compression" as it actually slowed it down instead of speeding it up * cope with compression/decompression threads failing by waiting till the previous thread has finished its work, thus serialising the work and using less ram, making success more likely * fix some dodgy callocs which weren't really allocating enough ram * destroy semaphores used in stream_in on closing the stream * minor output improvements ------------------------------------------------------------------- Wed Nov 24 17:36:35 UTC 2010 - pascal.bleser@opensuse.org - update to 0.543: * now copes when there are multiple stream 0 entries per chunk, which would cause a failure on massive file decompression * a mistake in which lzma windows were being set far too small at all times was fixed * the nice level of the main process was decreased compared to back end threads as it tends to be the rate limiting step ------------------------------------------------------------------- Sat Nov 20 11:38:35 UTC 2010 - pascal.bleser@opensuse.org - update to 0.542: * sane defaults are now chosen for memory usage because Linux ludicriously overcommits * a sliding mmap is used for compression windows greater than 2/3 RAM * testing of allocatable RAM was consolidated and simplified * minor tweaks were made to output * the size of the high buffer in sliding mmap was rounded up to one page * a little more was squeezed out of 32-bit compression windows * a problem with sliding mmap from not working from the 2nd pass onwards, causing a slowdown of death, was fixed ------------------------------------------------------------------- Thu Nov 18 16:54:52 UTC 2010 - pascal.bleser@opensuse.org - update to 0.541: * massive multithreading was implemented for decompression, making slower algorithms scale dramatically with number of CPUs, and completing huge scalability improvements on both compression and decompression * the output of zpaq consuming lots of CPU time and trampling on itself in the console was fixed * the control window is now ensured to be set appropriately on 32 bit * numerous minor output improvements were made * the docs and benchmarks were updated ------------------------------------------------------------------- Sat Nov 13 23:59:52 UTC 2010 - pascal.bleser@opensuse.org - update to 0.530: * a massive multithreading implementation allows a huge speed-up on SMP machines during compression * the -p option was added to override the number of processors to use * the -P option was deprecated * the size of all compression windows was increased to minimize the number of headers written * screen output was altered to suit threading ------------------------------------------------------------------- Sun Nov 7 11:14:20 UTC 2010 - pascal.bleser@opensuse.org - update to 0.5.2: * cases of extreme RAM usage on 32-bit failing was fixed by limiting zpaq to 600MB windows as well * page size is checked if possible instead of assuming it's always 4k * the progress output was improved * failure to chmod and failure to set nice level were changed to warnings only * a distinction between stderr messages and output was standardized ------------------------------------------------------------------- Fri Nov 5 23:33:46 UTC 2010 - pascal.bleser@opensuse.org - update to 0.5.1: * implements unlimited sized compression windows not constrained by RAM through a "sliding mmap" design * modifies the default compression windows to find the largest possible safely addressable RAM instead of guessing * these changes both have major compression improvements on files larger than RAM * improved screen output * more checks and error messages * numerous fixes, micro-optimisations, and cleanups * updated docs and benchmarks ------------------------------------------------------------------- Tue Nov 2 12:25:52 UTC 2010 - pascal.bleser@opensuse.org - update to 0.5: * variable byte width offsets are now used, and match lengths were shrunk for better compression and speed * a new file format was implemented * memory initialization was rewritten to find the maximum window size possible without failing * up to 44-bit sized offsets can be addressed on 32-bit machines on decompression * compression from stdin without temporary files is now possible * more robust fatal warnings were provided * there were numerous cleanups and tidying of code, and the documentation and comments were updated ------------------------------------------------------------------- Sat May 22 10:09:17 UTC 2010 -

pascal.bleser@opensuse.org - update to 0.43: * added stdin/stdout support * added test function * config files should now accept zpaq options * add a warning when attempting to decompress a file from a newer lrzip version ------------------------------------------------------------------- Mon Nov 30 07:19:52 UTC 2009 - pascal.bleser@opensuse.org - update to 0.42: * fixes the progress update in ZPAQ to not update with each byte, which was wasting heaps of CPU time * progress update has been changed to show which of 2 chunks are being compressed in ZPAQ ------------------------------------------------------------------- Sun Nov 29 22:17:14 UTC 2009 - pascal.bleser@opensuse.org - update to 0.41: * zpaq compression backend was added for extremely good but extremely slow compression (from the PAQ family of the best general compression algorithms around today) * chunk size passed to LZMA is now limited to 4GB to avoid library overflows * minor changes were made to the formatting output * lower limit of the -T threshhold was changed to 0 to allow disabling it * lzo_compresses check was added into zpaq and bzip2 as well since they're slow ------------------------------------------------------------------- Thu Nov 26 19:59:02 UTC 2009 -
