| Summary: Very High Ratio and Speed Compression Designed for Large Files | |
LRZIP is a compression program that can achieve very high compression ratios and speed when used with large files. It uses the combined compression algorithms of lzma for maximum compression, lzo for maximum speed, and the long range redundancy reduction of rzip. It is designed to scale with increases with RAM size, improving compression further. A choice of either size or speed optimizations allows for either better compression than even lzma can provide, or better speed than gzip, but with bzip2 sized compression levels.

can't preserve the original permissions (e.g. from STDIN)
* Wed Apr 27 2011 pascal.bleser@opensuse.org

requiring '-o -' for stdout
* update lrzip.conf to support encryption

* Wed Mar 23 2011 pascal.bleser@opensuse.org
- update to 0.601: no user-visible changes
* Wed Mar 23 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

* 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 2011 pascal.bleser@opensuse.org
- update to 0.570:

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

stdin/stdout
* missed temporary files are deleted
* a large clean up of the documentation was done
* Mon Feb 21 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 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 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 2010 pascal.bleser@opensuse.org
- update to 0.542:
* sane defaults are now chosen for memory usage because Linux ludicriously
overcommits

* 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 2010 pascal.bleser@opensuse.org

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
