0.9.0
|
||||
~~~~~
|
||||
First version.
|
||||
|
||||
|
||||
0.9.0a
|
||||
~~~~~~
|
||||
Removed 'ranlib' from Makefile, since most modern Unix-es
|
||||
don't need it, or even know about it.
|
||||
|
||||
|
||||
0.9.0b
|
||||
~~~~~~
|
||||
Fixed a problem with error reporting in bzip2.c. This does not effect
|
||||
the library in any way. Problem is: versions 0.9.0 and 0.9.0a (of the
|
||||
program proper) compress and decompress correctly, but give misleading
|
||||
error messages (internal panics) when an I/O error occurs, instead of
|
||||
reporting the problem correctly. This shouldn't give any data loss
|
||||
(as far as I can see), but is confusing.
|
||||
|
||||
Made the inline declarations disappear for non-GCC compilers.
|
||||
|
||||
|
||||
0.9.0c
|
||||
~~~~~~
|
||||
Fixed some problems in the library pertaining to some boundary cases.
|
||||
This makes the library behave more correctly in those situations. The
|
||||
fixes apply only to features (calls and parameters) not used by
|
||||
bzip2.c, so the non-fixedness of them in previous versions has no
|
||||
effect on reliability of bzip2.c.
|
||||
|
||||
In bzlib.c:
|
||||
* made zero-length BZ_FLUSH work correctly in bzCompress().
|
||||
* fixed bzWrite/bzRead to ignore zero-length requests.
|
||||
* fixed bzread to correctly handle read requests after EOF.
|
||||
* wrong parameter order in call to bzDecompressInit in
|
||||
bzBuffToBuffDecompress. Fixed.
|
||||
|
||||
In compress.c:
|
||||
* changed setting of nGroups in sendMTFValues() so as to
|
||||
do a bit better on small files. This _does_ effect
|
||||
bzip2.c.
|
||||
|
||||
|
||||
0.9.5a
|
||||
~~~~~~
|
||||
Major change: add a fallback sorting algorithm (blocksort.c)
|
||||
to give reasonable behaviour even for very repetitive inputs.
|
||||
Nuked --repetitive-best and --repetitive-fast since they are
|
||||
no longer useful.
|
||||
|
||||
Minor changes: mostly a whole bunch of small changes/
|
||||
bugfixes in the driver (bzip2.c). Changes pertaining to the
|
||||
user interface are:
|
||||
|
||||
allow decompression of symlink'd files to stdout
|
||||
decompress/test files even without .bz2 extension
|
||||
give more accurate error messages for I/O errors
|
||||
when compressing/decompressing to stdout, don't catch control-C
|
||||
read flags from BZIP2 and BZIP environment variables
|
||||
decline to break hard links to a file unless forced with -f
|
||||
allow -c flag even with no filenames
|
||||
preserve file ownerships as far as possible
|
||||
make -s -1 give the expected block size (100k)
|
||||
add a flag -q --quiet to suppress nonessential warnings
|
||||
stop decoding flags after --, so files beginning in - can be handled
|
||||
resolved inconsistent naming: bzcat or bz2cat ?
|
||||
bzip2 --help now returns 0
|
||||
|
||||
Programming-level changes are:
|
||||
|
||||
fixed syntax error in GET_LL4 for Borland C++ 5.02
|
||||
let bzBuffToBuffDecompress return BZ_DATA_ERROR{_MAGIC}
|
||||
fix overshoot of mode-string end in bzopen_or_bzdopen
|
||||
wrapped bzlib.h in #ifdef __cplusplus ... extern "C" { ... }
|
||||
close file handles under all error conditions
|
||||
added minor mods so it compiles with DJGPP out of the box
|
||||
fixed Makefile so it doesn't give problems with BSD make
|
||||
fix uninitialised memory reads in dlltest.c
|
||||
|
||||
0.9.5b
|
||||
~~~~~~
|
||||
Open stdin/stdout in binary mode for DJGPP.
|
||||
|
||||
0.9.5c
|
||||
~~~~~~
|
||||
Changed BZ_N_OVERSHOOT to be ... + 2 instead of ... + 1. The + 1
|
||||
version could cause the sorted order to be wrong in some extremely
|
||||
obscure cases. Also changed setting of quadrant in blocksort.c.
|
||||
|
||||
0.9.5d
|
||||
~~~~~~
|
||||
The only functional change is to make bzlibVersion() in the library
|
||||
return the correct string. This has no effect whatsoever on the
|
||||
functioning of the bzip2 program or library. Added a couple of casts
|
||||
so the library compiles without warnings at level 3 in MS Visual
|
||||
Studio 6.0. Included a Y2K statement in the file Y2K_INFO. All other
|
||||
changes are minor documentation changes.
|
||||
|
||||
1.0
|
||||
~~~
|
||||
Several minor bugfixes and enhancements:
|
||||
|
||||
* Large file support. The library uses 64-bit counters to
|
||||
count the volume of data passing through it. bzip2.c
|
||||
is now compiled with -D_FILE_OFFSET_BITS=64 to get large
|
||||
file support from the C library. -v correctly prints out
|
||||
file sizes greater than 4 gigabytes. All these changes have
|
||||
been made without assuming a 64-bit platform or a C compiler
|
||||
which supports 64-bit ints, so, except for the C library
|
||||
aspect, they are fully portable.
|
||||
|
||||
* Decompression robustness. The library/program should be
|
||||
robust to any corruption of compressed data, detecting and
|
||||
handling _all_ corruption, instead of merely relying on
|
||||
the CRCs. What this means is that the program should
|
||||
never crash, given corrupted data, and the library should
|
||||
always return BZ_DATA_ERROR.
|
||||
|
||||
* Fixed an obscure race-condition bug only ever observed on
|
||||
Solaris, in which, if you were very unlucky and issued
|
||||
control-C at exactly the wrong time, both input and output
|
||||
files would be deleted.
|
||||
|
||||
* Don't run out of file handles on test/decompression when
|
||||
large numbers of files have invalid magic numbers.
|
||||
|
||||
* Avoid library namespace pollution. Prefix all exported
|
||||
symbols with BZ2_.
|
||||
|
||||
* Minor sorting enhancements from my DCC2000 paper.
|
||||
|
||||
* Advance the version number to 1.0, so as to counteract the
|
||||
(false-in-this-case) impression some people have that programs
|
||||
with version numbers less than 1.0 are in some way, experimental,
|
||||
pre-release versions.
|
||||
|
||||
* Create an initial Makefile-libbz2_so to build a shared library.
|
||||
Yes, I know I should really use libtool et al ...
|
||||
|
||||
* Make the program exit with 2 instead of 0 when decompression
|
||||
fails due to a bad magic number (ie, an invalid bzip2 header).
|
||||
Also exit with 1 (as the manual claims :-) whenever a diagnostic
|
||||
message would have been printed AND the corresponding operation
|
||||
is aborted, for example
|
||||
bzip2: Output file xx already exists.
|
||||
When a diagnostic message is printed but the operation is not
|
||||
aborted, for example
|
||||
bzip2: Can't guess original name for wurble -- using wurble.out
|
||||
then the exit value 0 is returned, unless some other problem is
|
||||
also detected.
|
||||
|
||||
I think it corresponds more closely to what the manual claims now.
|
||||
|
||||
|
||||
1.0.1
|
||||
~~~~~
|
||||
* Modified dlltest.c so it uses the new BZ2_ naming scheme.
|
||||
* Modified makefile-msc to fix minor build probs on Win2k.
|
||||
* Updated README.COMPILATION.PROBLEMS.
|
||||
|
||||
There are no functionality changes or bug fixes relative to version
|
||||
1.0.0. This is just a documentation update + a fix for minor Win32
|
||||
build problems. For almost everyone, upgrading from 1.0.0 to 1.0.1 is
|
||||
utterly pointless. Don't bother.
|
||||
|
||||
|
||||
1.0.2
|
||||
~~~~~
|
||||
A bug fix release, addressing various minor issues which have appeared
|
||||
in the 18 or so months since 1.0.1 was released. Most of the fixes
|
||||
are to do with file-handling or documentation bugs. To the best of my
|
||||
knowledge, there have been no data-loss-causing bugs reported in the
|
||||
compression/decompression engine of 1.0.0 or 1.0.1.
|
||||
|
||||
Note that this release does not improve the rather crude build system
|
||||
for Unix platforms. The general plan here is to autoconfiscate/
|
||||
libtoolise 1.0.2 soon after release, and release the result as 1.1.0
|
||||
or perhaps 1.2.0. That, however, is still just a plan at this point.
|
||||
|
||||
Here are the changes in 1.0.2. Bug-reporters and/or patch-senders in
|
||||
parentheses.
|
||||
|
||||
* Fix an infinite segfault loop in 1.0.1 when a directory is
|
||||
encountered in -f (force) mode.
|
||||
(Trond Eivind Glomsrod, Nicholas Nethercote, Volker Schmidt)
|
||||
|
||||
* Avoid double fclose() of output file on certain I/O error paths.
|
||||
(Solar Designer)
|
||||
|
||||
* Don't fail with internal error 1007 when fed a long stream (> 48MB)
|
||||
of byte 251. Also print useful message suggesting that 1007s may be
|
||||
caused by bad memory.
|
||||
(noticed by Juan Pedro Vallejo, fixed by me)
|
||||
|
||||
* Fix uninitialised variable silly bug in demo prog dlltest.c.
|
||||
(Jorj Bauer)
|
||||
|
||||
* Remove 512-MB limitation on recovered file size for bzip2recover
|
||||
on selected platforms which support 64-bit ints. At the moment
|
||||
all GCC supported platforms, and Win32.
|
||||
(me, Alson van der Meulen)
|
||||
|
||||
* Hard-code header byte values, to give correct operation on platforms
|
||||
using EBCDIC as their native character set (IBM's OS/390).
|
||||
(Leland Lucius)
|
||||
|
||||
* Copy file access times correctly.
|
||||
(Marty Leisner)
|
||||
|
||||
* Add distclean and check targets to Makefile.
|
||||
(Michael Carmack)
|
||||
|
||||
* Parameterise use of ar and ranlib in Makefile. Also add $(LDFLAGS).
|
||||
(Rich Ireland, Bo Thorsen)
|
||||
|
||||
* Pass -p (create parent dirs as needed) to mkdir during make install.
|
||||
(Jeremy Fusco)
|
||||
|
||||
* Dereference symlinks when copying file permissions in -f mode.
|
||||
(Volker Schmidt)
|
||||
|
||||
* Majorly simplify implementation of uInt64_qrm10.
|
||||
(Bo Lindbergh)
|
||||
|
||||
* Check the input file still exists before deleting the output one,
|
||||
when aborting in cleanUpAndFail().
|
||||
(Joerg Prante, Robert Linden, Matthias Krings)
|
||||
|
||||
Also a bunch of patches courtesy of Philippe Troin, the Debian maintainer
|
||||
of bzip2:
|
||||
|
||||
* Wrapper scripts (with manpages): bzdiff, bzgrep, bzmore.
|
||||
|
||||
* Spelling changes and minor enhancements in bzip2.1.
|
||||
|
||||
* Avoid race condition between creating the output file and setting its
|
||||
interim permissions safely, by using fopen_output_safely().
|
||||
No changes to bzip2recover since there is no issue with file
|
||||
permissions there.
|
||||
|
||||
* do not print senseless report with -v when compressing an empty
|
||||
file.
|
||||
|
||||
* bzcat -f works on non-bzip2 files.
|
||||
|
||||
* do not try to escape shell meta-characters on unix (the shell takes
|
||||
care of these).
|
||||
|
||||
* added --fast and --best aliases for -1 -9 for gzip compatibility.
|
||||
|
||||
|
||||
1.0.3 (15 Feb 05)
|
||||
~~~~~~~~~~~~~~~~~
|
||||
Fixes some minor bugs since the last version, 1.0.2.
|
||||
|
||||
* Further robustification against corrupted compressed data.
|
||||
There are currently no known bitstreams which can cause the
|
||||
decompressor to crash, loop or access memory which does not
|
||||
belong to it. If you are using bzip2 or the library to
|
||||
decompress bitstreams from untrusted sources, an upgrade
|
||||
to 1.0.3 is recommended. This fixes CAN-2005-1260.
|
||||
|
||||
* The documentation has been converted to XML, from which html
|
||||
and pdf can be derived.
|
||||
|
||||
* Various minor bugs in the documentation have been fixed.
|
||||
|
||||
* Fixes for various compilation warnings with newer versions of
|
||||
gcc, and on 64-bit platforms.
|
||||
|
||||
* The BZ_NO_STDIO cpp symbol was not properly observed in 1.0.2.
|
||||
This has been fixed.
|
||||
|
||||
|
||||
1.0.4 (20 Dec 06)
|
||||
~~~~~~~~~~~~~~~~~
|
||||
Fixes some minor bugs since the last version, 1.0.3.
|
||||
|
||||
* Fix file permissions race problem (CAN-2005-0953).
|
||||
|
||||
* Avoid possible segfault in BZ2_bzclose. From Coverity's NetBSD
|
||||
scan.
|
||||
|
||||
* 'const'/prototype cleanups in the C code.
|
||||
|
||||
* Change default install location to /usr/local, and handle multiple
|
||||
'make install's without error.
|
||||
|
||||
* Sanitise file names more carefully in bzgrep. Fixes CAN-2005-0758
|
||||
to the extent that applies to bzgrep.
|
||||
|
||||
* Use 'mktemp' rather than 'tempfile' in bzdiff.
|
||||
|
||||
* Tighten up a couple of assertions in blocksort.c following automated
|
||||
analysis.
|
||||
|
||||
* Fix minor doc/comment bugs.
|
||||
|
||||
|
||||
1.0.5 (10 Dec 07)
|
||||
~~~~~~~~~~~~~~~~~
|
||||
Security fix only. Fixes CERT-FI 20469 as it applies to bzip2.

NAME
|
||||
bzip2, bunzip2 - a block-sorting file compressor, v1.0.4
|
||||
bzcat - decompresses files to stdout
|
||||
bzip2recover - recovers data from damaged bzip2 files
|
||||
|
||||
|
||||
SYNOPSIS
|
||||
bzip2 [ -cdfkqstvzVL123456789 ] [ filenames ... ]
|
||||
bunzip2 [ -fkvsVL ] [ filenames ... ]
|
||||
bzcat [ -s ] [ filenames ... ]
|
||||
bzip2recover filename
|
||||
|
||||
|
||||
DESCRIPTION
|
||||
bzip2 compresses files using the Burrows-Wheeler block
|
||||
sorting text compression algorithm, and Huffman coding.
|
||||
Compression is generally considerably better than that
|
||||
achieved by more conventional LZ77/LZ78-based compressors,
|
||||
and approaches the performance of the PPM family of sta-
|
||||
tistical compressors.
|
||||
|
||||
The command-line options are deliberately very similar to
|
||||
those of GNU gzip, but they are not identical.
|
||||
|
||||
bzip2 expects a list of file names to accompany the com-
|
||||
mand-line flags. Each file is replaced by a compressed
|
||||
version of itself, with the name "original_name.bz2".
|
||||
Each compressed file has the same modification date, per-
|
||||
missions, and, when possible, ownership as the correspond-
|
||||
ing original, so that these properties can be correctly
|
||||
restored at decompression time. File name handling is
|
||||
naive in the sense that there is no mechanism for preserv-
|
||||
ing original file names, permissions, ownerships or dates
|
||||
in filesystems which lack these concepts, or have serious
|
||||
file name length restrictions, such as MS-DOS.
|
||||
|
||||
bzip2 and bunzip2 will by default not overwrite existing
|
||||
files. If you want this to happen, specify the -f flag.
|
||||
|
||||
If no file names are specified, bzip2 compresses from
|
||||
standard input to standard output. In this case, bzip2
|
||||
will decline to write compressed output to a terminal, as
|
||||
this would be entirely incomprehensible and therefore
|
||||
pointless.
|
||||
|
||||
bunzip2 (or bzip2 -d) decompresses all specified files.
|
||||
Files which were not created by bzip2 will be detected and
|
||||
ignored, and a warning issued. bzip2 attempts to guess
|
||||
the filename for the decompressed file from that of the
|
||||
compressed file as follows:
|
||||
|
||||
filename.bz2 becomes filename
|
||||
filename.bz becomes filename
|
||||
filename.tbz2 becomes filename.tar
|
||||
filename.tbz becomes filename.tar
|
||||
anyothername becomes anyothername.out
|
||||
|
||||
If the file does not end in one of the recognised endings,
|
||||
.bz2, .bz, .tbz2 or .tbz, bzip2 complains that it cannot
|
||||
guess the name of the original file, and uses the original
|
||||
name with .out appended.
|
||||
|
||||
As with compression, supplying no filenames causes decom-
|
||||
pression from standard input to standard output.
|
||||
|
||||
bunzip2 will correctly decompress a file which is the con-
|
||||
catenation of two or more compressed files. The result is
|
||||
the concatenation of the corresponding uncompressed files.
|
||||
Integrity testing (-t) of concatenated compressed files is
|
||||
also supported.
|
||||
|
||||
You can also compress or decompress files to the standard
|
||||
output by giving the -c flag. Multiple files may be com-
|
||||
pressed and decompressed like this. The resulting outputs
|
||||
are fed sequentially to stdout. Compression of multiple
|
||||
files in this manner generates a stream containing multi-
|
||||
ple compressed file representations. Such a stream can be
|
||||
decompressed correctly only by bzip2 version 0.9.0 or
|
||||
later. Earlier versions of bzip2 will stop after decom-
|
||||
pressing the first file in the stream.
|
||||
|
||||
bzcat (or bzip2 -dc) decompresses all specified files to
|
||||
the standard output.
|
||||
|
||||
bzip2 will read arguments from the environment variables
|
||||
BZIP2 and BZIP, in that order, and will process them
|
||||
before any arguments read from the command line. This
|
||||
gives a convenient way to supply default arguments.
|
||||
|
||||
Compression is always performed, even if the compressed
|
||||
file is slightly larger than the original. Files of less
|
||||
than about one hundred bytes tend to get larger, since the
|
||||
compression mechanism has a constant overhead in the
|
||||
region of 50 bytes. Random data (including the output of
|
||||
most file compressors) is coded at about 8.05 bits per
|
||||
byte, giving an expansion of around 0.5%.
|
||||
|
||||
As a self-check for your protection, bzip2 uses 32-bit
|
||||
CRCs to make sure that the decompressed version of a file
|
||||
is identical to the original. This guards against corrup-
|
||||
tion of the compressed data, and against undetected bugs
|
||||
in bzip2 (hopefully very unlikely). The chances of data
|
||||
corruption going undetected is microscopic, about one
|
||||
chance in four billion for each file processed. Be aware,
|
||||
though, that the check occurs upon decompression, so it
|
||||
can only tell you that something is wrong. It can't help
|
||||
you recover the original uncompressed data. You can use
|
||||
bzip2recover to try to recover data from damaged files.
|
||||
|
||||
Return values: 0 for a normal exit, 1 for environmental
|
||||
problems (file not found, invalid flags, I/O errors, &c),
|
||||
2 to indicate a corrupt compressed file, 3 for an internal
|
||||
consistency error (eg, bug) which caused bzip2 to panic.
|
||||
|
||||
|
||||
OPTIONS
|
||||
-c --stdout
|
||||
Compress or decompress to standard output.
|
||||
|
||||
-d --decompress
|
||||
Force decompression. bzip2, bunzip2 and bzcat are
|
||||
really the same program, and the decision about
|
||||
what actions to take is done on the basis of which
|
||||
name is used. This flag overrides that mechanism,
|
||||
and forces bzip2 to decompress.
|
||||
|
||||
-z --compress
|
||||
The complement to -d: forces compression,
|
||||
regardless of the invocation name.
|
||||
|
||||
-t --test
|
||||
Check integrity of the specified file(s), but don't
|
||||
decompress them. This really performs a trial
|
||||
decompression and throws away the result.
|
||||
|
||||
-f --force
|
||||
Force overwrite of output files. Normally, bzip2
|
||||
will not overwrite existing output files. Also
|
||||
forces bzip2 to break hard links to files, which it
|
||||
otherwise wouldn't do.
|
||||
|
||||
bzip2 normally declines to decompress files which
|
||||
don't have the correct magic header bytes. If
|
||||
forced (-f), however, it will pass such files
|
||||
through unmodified. This is how GNU gzip behaves.
|
||||
|
||||
-k --keep
|
||||
Keep (don't delete) input files during compression
|
||||
or decompression.
|
||||
|
||||
-s --small
|
||||
Reduce memory usage, for compression, decompression
|
||||
and testing. Files are decompressed and tested
|
||||
using a modified algorithm which only requires 2.5
|
||||
bytes per block byte. This means any file can be
|
||||
decompressed in 2300k of memory, albeit at about
|
||||
half the normal speed.
|
||||
|
||||
During compression, -s selects a block size of
|
||||
200k, which limits memory use to around the same
|
||||
figure, at the expense of your compression ratio.
|
||||
In short, if your machine is low on memory (8
|
||||
megabytes or less), use -s for everything. See
|
||||
MEMORY MANAGEMENT below.
|
||||
|
||||
-q --quiet
|
||||
Suppress non-essential warning messages. Messages
|
||||
pertaining to I/O errors and other critical events
|
||||
will not be suppressed.
|
||||
|
||||
-v --verbose
|
||||
Verbose mode -- show the compression ratio for each
|
||||
file processed. Further -v's increase the ver-
|
||||
bosity level, spewing out lots of information which
|
||||
is primarily of interest for diagnostic purposes.
|
||||
|
||||
-L --license -V --version
|
||||
Display the software version, license terms and
|
||||
conditions.
|
||||
|
||||
-1 (or --fast) to -9 (or --best)
|
||||
Set the block size to 100 k, 200 k .. 900 k when
|
||||
compressing. Has no effect when decompressing.
|
||||
See MEMORY MANAGEMENT below. The --fast and --best
|
||||
aliases are primarily for GNU gzip compatibility.
|
||||
In particular, --fast doesn't make things signifi-
|
||||
cantly faster. And --best merely selects the
|
||||
default behaviour.
|
||||
|
||||
-- Treats all subsequent arguments as file names, even
|
||||
if they start with a dash. This is so you can han-
|
||||
dle files with names beginning with a dash, for
|
||||
example: bzip2 -- -myfilename.
|
||||
|
||||
--repetitive-fast --repetitive-best
|
||||
These flags are redundant in versions 0.9.5 and
|
||||
above. They provided some coarse control over the
|
||||
behaviour of the sorting algorithm in earlier ver-
|
||||
sions, which was sometimes useful. 0.9.5 and above
|
||||
have an improved algorithm which renders these
|
||||
flags irrelevant.
|
||||
|
||||
|
||||
MEMORY MANAGEMENT
|
||||
bzip2 compresses large files in blocks. The block size
|
||||
affects both the compression ratio achieved, and the
|
||||
amount of memory needed for compression and decompression.
|
||||
The flags -1 through -9 specify the block size to be
|
||||
100,000 bytes through 900,000 bytes (the default) respec-
|
||||
tively. At decompression time, the block size used for
|
||||
compression is read from the header of the compressed
|
||||
file, and bunzip2 then allocates itself just enough memory
|
||||
to decompress the file. Since block sizes are stored in
|
||||
compressed files, it follows that the flags -1 to -9 are
|
||||
irrelevant to and so ignored during decompression.
|
||||
|
||||
Compression and decompression requirements, in bytes, can
|
||||
be estimated as:
|
||||
|
||||
Compression: 400k + ( 8 x block size )
|
||||
|
||||
Decompression: 100k + ( 4 x block size ), or
|
||||
100k + ( 2.5 x block size )
|
||||
|
||||
Larger block sizes give rapidly diminishing marginal
|
||||
returns. Most of the compression comes from the first two
|
||||
or three hundred k of block size, a fact worth bearing in
|
||||
mind when using bzip2 on small machines. It is also
|
||||
important to appreciate that the decompression memory
|
||||
requirement is set at compression time by the choice of
|
||||
block size.
|
||||
|
||||
For files compressed with the default 900k block size,
|
||||
bunzip2 will require about 3700 kbytes to decompress. To
|
||||
support decompression of any file on a 4 megabyte machine,
|
||||
bunzip2 has an option to decompress using approximately
|
||||
half this amount of memory, about 2300 kbytes. Decompres-
|
||||
sion speed is also halved, so you should use this option
|
||||
only where necessary. The relevant flag is -s.
|
||||
|
||||
In general, try and use the largest block size memory con-
|
||||
straints allow, since that maximises the compression
|
||||
achieved. Compression and decompression speed are virtu-
|
||||
ally unaffected by block size.
|
||||
|
||||
Another significant point applies to files which fit in a
|
||||
single block -- that means most files you'd encounter
|
||||
using a large block size. The amount of real memory
|
||||
touched is proportional to the size of the file, since the
|
||||
file is smaller than a block. For example, compressing a
|
||||
file 20,000 bytes long with the flag -9 will cause the
|
||||
compressor to allocate around 7600k of memory, but only
|
||||
touch 400k + 20000 * 8 = 560 kbytes of it. Similarly, the
|
||||
decompressor will allocate 3700k but only touch 100k +
|
||||
20000 * 4 = 180 kbytes.
|
||||
|
||||
Here is a table which summarises the maximum memory usage
|
||||
for different block sizes. Also recorded is the total
|
||||
compressed size for 14 files of the Calgary Text Compres-
|
||||
sion Corpus totalling 3,141,622 bytes. This column gives
|
||||
some feel for how compression varies with block size.
|
||||
These figures tend to understate the advantage of larger
|
||||
block sizes for larger files, since the Corpus is domi-
|
||||
nated by smaller files.

RECOVERING DATA FROM DAMAGED FILES
|
||||
bzip2 compresses files in blocks, usually 900kbytes long.
|
||||
Each block is handled independently. If a media or trans-
|
||||
mission error causes a multi-block .bz2 file to become
|
||||
damaged, it may be possible to recover data from the
|
||||
undamaged blocks in the file.
|
||||
|
||||
The compressed representation of each block is delimited
|
||||
by a 48-bit pattern, which makes it possible to find the
|
||||
block boundaries with reasonable certainty. Each block
|
||||
also carries its own 32-bit CRC, so damaged blocks can be
|
||||
distinguished from undamaged ones.
|
||||
|
||||
bzip2recover is a simple program whose purpose is to
|
||||
search for blocks in .bz2 files, and write each block out
|
||||
into its own .bz2 file. You can then use bzip2 -t to test
|
||||
the integrity of the resulting files, and decompress those
|
||||
which are undamaged.
|
||||
|
||||
bzip2recover takes a single argument, the name of the dam-
|
||||
aged file, and writes a number of files
|
||||
"rec00001file.bz2", "rec00002file.bz2", etc, containing
|
||||
the extracted blocks. The output filenames are
|
||||
designed so that the use of wildcards in subsequent pro-
|
||||
cessing -- for example, "bzip2 -dc rec*file.bz2 > recov-
|
||||
ered_data" -- processes the files in the correct order.
|
||||
|
||||
bzip2recover should be of most use dealing with large .bz2
|
||||
files, as these will contain many blocks. It is clearly
|
||||
futile to use it on damaged single-block files, since a
|
||||
damaged block cannot be recovered. If you wish to min-
|
||||
imise any potential data loss through media or transmis-
|
||||
sion errors, you might consider compressing with a smaller
|
||||
block size.
|
||||
|
||||
|
||||
PERFORMANCE NOTES
|
||||
The sorting phase of compression gathers together similar
|
||||
strings in the file. Because of this, files containing
|
||||
very long runs of repeated symbols, like "aabaabaabaab
|
||||
..." (repeated several hundred times) may compress more
|
||||
slowly than normal. Versions 0.9.5 and above fare much
|
||||
better than previous versions in this respect. The ratio
|
||||
between worst-case and average-case compression time is in
|
||||
the region of 10:1. For previous versions, this figure
|
||||
was more like 100:1. You can use the -vvvv option to mon-
|
||||
itor progress in great detail, if you want.
|
||||
|
||||
Decompression speed is unaffected by these phenomena.
|
||||
|
||||
bzip2 usually allocates several megabytes of memory to
|
||||
operate in, and then charges all over it in a fairly ran-
|
||||
dom fashion. This means that performance, both for com-
|
||||
pressing and decompressing, is largely determined by the
|
||||
speed at which your machine can service cache misses.
|
||||
Because of this, small changes to the code to reduce the
|
||||
miss rate have been observed to give disproportionately
|
||||
large performance improvements. I imagine bzip2 will per-
|
||||
form best on machines with very large caches.
|
||||
|
||||
|
||||
CAVEATS
|
||||
I/O error messages are not as helpful as they could be.
|
||||
bzip2 tries hard to detect I/O errors and exit cleanly,
|
||||
but the details of what the problem is sometimes seem
|
||||
rather misleading.
|
||||
|
||||
This manual page pertains to version 1.0.4 of bzip2. Com-
|
||||
pressed data created by this version is entirely forwards
|
||||
and backwards compatible with the previous public
|
||||
releases, versions 0.1pl2, 0.9.0, 0.9.5, 1.0.0, 1.0.1,
|
||||
1.0.2 and 1.0.3, but with the following exception: 0.9.0
|
||||
and above can correctly decompress multiple concatenated
|
||||
compressed files. 0.1pl2 cannot do this; it will stop
|
||||
after decompressing just the first file in the stream.
|
||||
|
||||
bzip2recover versions prior to 1.0.2 used 32-bit integers
|
||||
to represent bit positions in compressed files, so they
|
||||
could not handle compressed files more than 512 megabytes
|
||||
long. Versions 1.0.2 and above use 64-bit ints on some
|
||||
platforms which support them (GNU supported targets, and
|
||||
Windows). To establish whether or not bzip2recover was
|
||||
built with such a limitation, run it without arguments.
|
||||
In any event you can build yourself an unlimited version
|
||||
if you can recompile it with MaybeUInt64 set to be an
|
||||
unsigned 64-bit integer.

|
||||
|
||||
The ideas embodied in bzip2 are due to (at least) the fol-
|
||||
lowing people: Michael Burrows and David Wheeler (for the
|
||||
block sorting transformation), David Wheeler (again, for
|
||||
the Huffman coder), Peter Fenwick (for the structured cod-
|
||||
ing model in the original bzip, and many refinements), and
|
||||
Alistair Moffat, Radford Neal and Ian Witten (for the
|
||||
arithmetic coder in the original bzip). I am much
|
||||
indebted for their help, support and advice. See the man-
|
||||
ual in the source distribution for pointers to sources of
|
||||
documentation. Christian von Roques encouraged me to look
|
||||
for faster sorting algorithms, so as to speed up compres-
|
||||
sion. Bela Lubkin encouraged me to improve the worst-case
|
||||
compression performance. Donna Robinson XMLised the docu-
|
||||
mentation. The bz* scripts are derived from those of GNU
|
||||
gzip. Many people sent patches, helped with portability
|
||||
problems, lent machines, gave advice and were generally
|
||||
helpful.

looping. However, this count-scaling step is only needed if

one of the generated Huffman code words is longer than

maxLen, which up to and including version 1.0.2 was 20 bits,

changed to 17 bits, which has minimal effect on compression

ratio, but does mean this scaling step is used from time to

time, enough to verify that it works.

This means that bzip2-1.0.3 and later will only produce

Huffman codes with a maximum length of 17 bits. However, in

order to preserve backwards compatibility with bitstreams
