This file is part of bzip2/libbzip2, a program and library for
lossless, block-sorting data compression.
bzip2/libbzip2 version 1.0.8 of 13 July 2019
Copyright (C) 1996-2019 Julian Seward <jseward@acm.org>
Please read the WARNING, DISCLAIMER and PATENTS sections in the
README file.
This program is released under the terms of the license contained
in the file LICENSE.
------------------------------------------------------------------
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.
1.0.6 (6 Sept 10)
~~~~~~~~~~~~~~~~~
* Security fix for CVE-2010-0405. This was reported by Mikolaj
Izdebski.
* Make the documentation build on Ubuntu 10.04
1.0.7 (27 Jun 19)
~~~~~~~~~~~~~~~~~
* Fix undefined behavior in the macros SET_BH, CLEAR_BH, & ISSET_BH
* bzip2: Fix return value when combining --test,-t and -q.
* bzip2recover: Fix buffer overflow for large argv[0]
* bzip2recover: Fix use after free issue with outFile (CVE-2016-3189)
* Make sure nSelectors is not out of range (CVE-2019-12900)
1.0.8 (13 Jul 19)
~~~~~~~~~~~~~~~~~
* Accept as many selectors as the file format allows.
This relaxes the fix for CVE-2019-12900 from 1.0.7
so that bzip2 allows decompression of bz2 files that
use (too) many selectors again.
* Fix handling of large (> 4GB) files on Windows.
* Cleanup of bzdiff and bzgrep scripts so they don't use
any bash extensions and handle multiple archives correctly.
* There is now a bz2-files testsuite at
https://sourceware.org/git/bzip2-tests.git

This is the README for bzip2/libzip2.
This version is fully compatible with the previous public releases.
------------------------------------------------------------------
This file is part of bzip2/libbzip2, a program and library for
lossless, block-sorting data compression.
bzip2/libbzip2 version 1.0.8 of 13 July 2019
Copyright (C) 1996-2019 Julian Seward <jseward@acm.org>
Please read the WARNING, DISCLAIMER and PATENTS sections in this file.
This program is released under the terms of the license contained
in the file LICENSE.
------------------------------------------------------------------
Complete documentation is available in Postscript form (manual.ps),
PDF (manual.pdf) or html (manual.html). A plain-text version of the
manual page is available as bzip2.txt.
HOW TO BUILD -- UNIX
Type 'make'. This builds the library libbz2.a and then the programs
bzip2 and bzip2recover. Six self-tests are run. If the self-tests
complete ok, carry on to installation:
To install in /usr/local/bin, /usr/local/lib, /usr/local/man and
/usr/local/include, type
make install
To install somewhere else, eg, /xxx/yyy/{bin,lib,man,include}, type
make install PREFIX=/xxx/yyy
If you are (justifiably) paranoid and want to see what 'make install'
is going to do, you can first do
make -n install or
make -n install PREFIX=/xxx/yyy respectively.
The -n instructs make to show the commands it would execute, but not
actually execute them.
HOW TO BUILD -- UNIX, shared library libbz2.so.
Do 'make -f Makefile-libbz2_so'. This Makefile seems to work for
Linux-ELF (RedHat 7.2 on an x86 box), with gcc. I make no claims
that it works for any other platform, though I suspect it probably
will work for most platforms employing both ELF and gcc.
bzip2-shared, a client of the shared library, is also built, but not
self-tested. So I suggest you also build using the normal Makefile,
since that conducts a self-test. A second reason to prefer the
version statically linked to the library is that, on x86 platforms,
building shared objects makes a valuable register (%ebx) unavailable
to gcc, resulting in a slowdown of 10%-20%, at least for bzip2.
Important note for people upgrading .so's from 0.9.0/0.9.5 to version
1.0.X. All the functions in the library have been renamed, from (eg)
bzCompress to BZ2_bzCompress, to avoid namespace pollution.
Unfortunately this means that the libbz2.so created by
Makefile-libbz2_so will not work with any program which used an older
version of the library. I do encourage library clients to make the
effort to upgrade to use version 1.0, since it is both faster and more
robust than previous versions.
HOW TO BUILD -- Windows 95, NT, DOS, Mac, etc.
It's difficult for me to support compilation on all these platforms.
My approach is to collect binaries for these platforms, and put them
on the master web site (https://sourceware.org/bzip2/). Look there. However
(FWIW), bzip2-1.0.X is very standard ANSI C and should compile
unmodified with MS Visual C. If you have difficulties building, you
might want to read README.COMPILATION.PROBLEMS.
At least using MS Visual C++ 6, you can build from the unmodified
sources by issuing, in a command shell:
nmake -f makefile.msc
(you may need to first run the MSVC-provided script VCVARS32.BAT
so as to set up paths to the MSVC tools correctly).
VALIDATION
Correct operation, in the sense that a compressed file can always be
decompressed to reproduce the original, is obviously of paramount
importance. To validate bzip2, I used a modified version of Mark
Nelson's churn program. Churn is an automated test driver which
recursively traverses a directory structure, using bzip2 to compress
and then decompress each file it encounters, and checking that the
decompressed data is the same as the original.
Please read and be aware of the following:
WARNING:
This program and library (attempts to) compress data by
performing several non-trivial transformations on it.
Unless you are 100% familiar with *all* the algorithms
contained herein, and with the consequences of modifying them,
you should NOT meddle with the compression or decompression
machinery. Incorrect changes can and very likely *will*
lead to disastrous loss of data.
DISCLAIMER:
I TAKE NO RESPONSIBILITY FOR ANY LOSS OF DATA ARISING FROM THE
USE OF THIS PROGRAM/LIBRARY, HOWSOEVER CAUSED.
Every compression of a file implies an assumption that the
compressed file can be decompressed to reproduce the original.
Great efforts in design, coding and testing have been made to
ensure that this program works correctly. However, the complexity
of the algorithms, and, in particular, the presence of various
special cases in the code which occur with very low but non-zero
probability make it impossible to rule out the possibility of bugs
remaining in the program. DO NOT COMPRESS ANY DATA WITH THIS
PROGRAM UNLESS YOU ARE PREPARED TO ACCEPT THE POSSIBILITY, HOWEVER
SMALL, THAT THE DATA WILL NOT BE RECOVERABLE.
That is not to say this program is inherently unreliable.
Indeed, I very much hope the opposite is true. bzip2/libbzip2
has been carefully constructed and extensively tested.
PATENTS:
To the best of my knowledge, bzip2/libbzip2 does not use any
patented algorithms. However, I do not have the resources
to carry out a patent search. Therefore I cannot give any
guarantee of the above statement.
WHAT'S NEW IN 0.9.0 (as compared to 0.1pl2) ?
* Approx 10% faster compression, 30% faster decompression
* -t (test mode) is a lot quicker
* Can decompress concatenated compressed files
* Programming interface, so programs can directly read/write .bz2 files
* Less restrictive (BSD-style) licensing
* Flag handling more compatible with GNU gzip
* Much more documentation, i.e., a proper user manual
* Hopefully, improved portability (at least of the library)
WHAT'S NEW IN 0.9.5 ?
* Compression speed is much less sensitive to the input
data than in previous versions. Specifically, the very
slow performance caused by repetitive data is fixed.
* Many small improvements in file and flag handling.
* A Y2K statement.
WHAT'S NEW IN 1.0.x ?
See the CHANGES file.
I hope you find bzip2 useful. Feel free to contact the developers at
bzip2-devel@sourceware.org
if you have any suggestions or queries. Many people mailed me with
comments, suggestions and patches after the releases of bzip-0.15,
bzip-0.21, and bzip2 versions 0.1pl2, 0.9.0, 0.9.5, 1.0.0, 1.0.1,
1.0.2 and 1.0.3, and the changes in bzip2 are largely a result of this
feedback. I thank you for your comments.

------------------------------------------------------------------
bzip2 should compile without problems on the vast majority of
platforms. Using the supplied Makefile, I've built and tested it
myself for x86-linux and amd64-linux. With makefile.msc, Visual C++
6.0 and nmake, you can build a native Win32 version too. Large file
support seems to work correctly on at least on amd64-linux.
When I say "large file" I mean a file of size 2,147,483,648 (2^31)
bytes or above. Many older OSs can't handle files above this size,
but many newer ones can. Large files are pretty huge -- most files
you'll encounter are not Large Files.
Early versions of bzip2 (0.1, 0.9.0, 0.9.5) compiled on a wide variety
of platforms without difficulty, and I hope this version will continue
in that tradition. However, in order to support large files, I've had
to include the define -D_FILE_OFFSET_BITS=64 in the Makefile. This
can cause problems.
The technique of adding -D_FILE_OFFSET_BITS=64 to get large file
support is, as far as I know, the Recommended Way to get correct large
file support. For more details, see the Large File Support
Specification, published by the Large File Summit, at
http://ftp.sas.com/standards/large.file
As a general comment, if you get compilation errors which you think
are related to large file support, try removing the above define from
the Makefile, ie, delete the line
BIGFILES=-D_FILE_OFFSET_BITS=64
from the Makefile, and do 'make clean ; make'. This will give you a
version of bzip2 without large file support, which, for most
applications, is probably not a problem.
Alternatively, try some of the platform-specific hints listed below.
You can use the spewG.c program to generate huge files to test bzip2's
large file support, if you are feeling paranoid. Be aware though that
any compilation problems which affect bzip2 will also affect spewG.c,
alas.
AIX: I have reports that for large file support, you need to specify
-D_LARGE_FILES rather than -D_FILE_OFFSET_BITS=64. I have not tested
this myself.

The script xmlproc.sh takes an xml file as input,
and processes it to create .pdf, .html or .ps output.
It uses format.pl, a perl script to format <pre> blocks nicely,
and add CDATA tags so writers do not have to use eg. &lt;
The file "entities.xml" must be edited to reflect current
version, year, etc.
Usage:
./xmlproc.sh -v manual.xml
Validates an xml file to ensure no dtd-compliance errors
./xmlproc.sh -html manual.xml
Output: manual.html
./xmlproc.sh -pdf manual.xml
Output: manual.pdf
./xmlproc.sh -ps manual.xml
Output: manual.ps
Notum bene:
- pdfxmltex barfs if given a filename with an underscore in it
- xmltex won't work yet - there's a bug in passivetex
which we are all waiting for Sebastian to fix.
So we are going the xml -> pdf -> ps route for the time being,
using pdfxmltex.

.SH NAME
bzip2, bunzip2 \- a block-sorting file compressor, v1.0.8
.br
bzcat \- decompresses files to stdout
.br
bzip2recover \- recovers data from damaged bzip2 files
.SH SYNOPSIS

.RB [ " \-s " ]
[
.I "filenames \&..."
]
.br
.B bzip2recover
.I "filename"
.SH DESCRIPTION
.I 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 statistical compressors.
The command-line options are deliberately very similar to
those of
.I GNU gzip,
but they are not identical.
.I bzip2
expects a list of file names to accompany the
command-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, permissions, and, when possible,
ownership as the corresponding 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 preserving original
file names, permissions, ownerships or dates in filesystems which lack
these concepts, or have serious file name length restrictions, such as
MS-DOS.
.I bzip2
and
.I bunzip2
will by default not overwrite existing
files. If you want this to happen, specify the \-f flag.
If no file names are specified,
.I bzip2
compresses from standard
input to standard output. In this case,
.I bzip2
will decline to
write compressed output to a terminal, as this would be entirely
incomprehensible and therefore pointless.
.I bunzip2
(or
.I bzip2 \-d)
decompresses all
specified files. Files which were not created by
.I bzip2
will be detected and ignored, and a warning issued.
.I 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,
.I .bz2,
.I .bz,
.I .tbz2
or
.I .tbz,
.I bzip2
complains that it cannot
guess the name of the original file, and uses the original name
with
.I .out
appended.
As with compression, supplying no
filenames causes decompression from
standard input to standard output.
.I bunzip2
will correctly decompress a file which is the
concatenation 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 compressed and
decompressed like this. The resulting outputs are fed sequentially to
stdout. Compression of multiple files
in this manner generates a stream
containing multiple compressed file representations. Such a stream
can be decompressed correctly only by
.I bzip2
version 0.9.0 or
later. Earlier versions of
.I bzip2
will stop after decompressing
the first file in the stream.
.I bzcat
(or
.I bzip2 -dc)
decompresses all specified files to
the standard output.
.I bzip2
will read arguments from the environment variables
.I BZIP2
and
.I 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,
.I
bzip2
uses 32-bit CRCs to
make sure that the decompressed version of a file is identical to the
original. This guards against corruption of the compressed data, and
against undetected bugs in
.I 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
.I 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
.I bzip2
to panic.
.SH OPTIONS
.TP
.B \-c --stdout
Compress or decompress to standard output.
.TP
.B \-d --decompress
Force decompression.
.I bzip2,
.I bunzip2
and
.I 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
.I bzip2
to decompress.
.TP
.B \-z --compress
The complement to \-d: forces compression, regardless of the
invocation name.
.TP
.B \-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.
.TP
.B \-f --force
Force overwrite of output files. Normally,
.I bzip2
will not overwrite
existing output files. Also forces
.I 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.
.TP
.B \-k --keep
Keep (don't delete) input files during compression
or decompression.
.TP
.B \-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.
.TP
.B \-q --quiet
Suppress non-essential warning messages. Messages pertaining to
I/O errors and other critical events will not be suppressed.
.TP
.B \-v --verbose
Verbose mode -- show the compression ratio for each file processed.
Further \-v's increase the verbosity level, spewing out lots of
information which is primarily of interest for diagnostic purposes.
.TP
.B \-L --license -V --version
Display the software version, license terms and conditions.
.TP
.B \-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
significantly faster.
And \-\-best merely selects the default behaviour.
.TP
.B \--
Treats all subsequent arguments as file names, even if they start
with a dash. This is so you can handle files with names beginning
with a dash, for example: bzip2 \-- \-myfilename.
.TP
.B \--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 versions, which was sometimes useful. 0.9.5 and above have an
improved algorithm which renders these flags irrelevant.
.SH MEMORY MANAGEMENT
.I 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) respectively. At decompression time, the block size used for
compression is read from the header of the compressed file, and
.I 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
.I 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,
.I bunzip2
will require about 3700 kbytes to decompress. To support decompression
of any file on a 4 megabyte machine,
.I bunzip2
has an option to
decompress using approximately half this amount of memory, about 2300
kbytes. Decompression 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 constraints allow,
since that maximises the compression achieved. Compression and
decompression speed are virtually 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 Compression 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 dominated by smaller files.

.SH RECOVERING DATA FROM DAMAGED FILES
.I bzip2
compresses files in blocks, usually 900kbytes long. Each
block is handled independently. If a media or transmission 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.
.I 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
.I bzip2
\-t
to test the
integrity of the resulting files, and decompress those which are
undamaged.
.I bzip2recover
takes a single argument, the name of the damaged 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 processing -- for example,
"bzip2 -dc rec*file.bz2 > recovered_data" -- processes the files in
the correct order.
.I 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 minimise
any potential data loss through media or transmission errors,
you might consider compressing with a smaller
block size.
.SH 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 monitor progress in great detail, if you want.
Decompression speed is unaffected by these phenomena.
.I bzip2
usually allocates several megabytes of memory to operate
in, and then charges all over it in a fairly random fashion. This means
that performance, both for compressing 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
.I bzip2
will perform best on machines with very large caches.
.SH CAVEATS
I/O error messages are not as helpful as they could be.
.I 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 1.0.8 of
.I bzip2.
Compressed 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 above, 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.
.I 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
.I bzip2
are due to (at least) the following
people: Michael Burrows and David Wheeler (for the block sorting
transformation), David Wheeler (again, for the Huffman coder), Peter
Fenwick (for the structured coding model in the original
.I bzip,
and many refinements), and Alistair Moffat, Radford Neal and Ian Witten
(for the arithmetic coder in the original
.I bzip).
I am much
indebted for their help, support and advice. See the manual 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 compression. Bela Lubkin encouraged me to improve the
worst-case compression performance.
Donna Robinson XMLised the documentation.
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.

_b_z_i_p_2 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 _G_N_U _g_z_i_p_, but they are not identical.
_b_z_i_p_2 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.
_b_z_i_p_2 and _b_u_n_z_i_p_2 will by default not overwrite existing
files. If you want this to happen, specify the −f flag.
If no file names are specified, _b_z_i_p_2 compresses from
standard input to standard output. In this case, _b_z_i_p_2
will decline to write compressed output to a terminal, as
this would be entirely incomprehensible and therefore
pointless.
_b_u_n_z_i_p_2 (or _b_z_i_p_2 _−_d_) decompresses all specified files.
Files which were not created by _b_z_i_p_2 will be detected and
ignored, and a warning issued. _b_z_i_p_2 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,
_._b_z_2_, _._b_z_, _._t_b_z_2 or _._t_b_z_, _b_z_i_p_2 complains that it cannot
guess the name of the original file, and uses the original
name with _._o_u_t appended.
As with compression, supplying no filenames causes decom­
pression from standard input to standard output.
_b_u_n_z_i_p_2 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 _b_z_i_p_2 version 0.9.0 or
later. Earlier versions of _b_z_i_p_2 will stop after decom­
pressing the first file in the stream.
_b_z_c_a_t (or _b_z_i_p_2 _‐_d_c_) decompresses all specified files to
the standard output.
_b_z_i_p_2 will read arguments from the environment variables
_B_Z_I_P_2 and _B_Z_I_P_, 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, _b_z_i_p_2 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 _b_z_i_p_2 (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
_b_z_i_p_2_r_e_c_o_v_e_r 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 _b_z_i_p_2 to panic.

_b_z_i_p_2 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 _b_u_n_z_i_p_2 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 _b_z_i_p_2 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,
_b_u_n_z_i_p_2 will require about 3700 kbytes to decompress. To
support decompression of any file on a 4 megabyte machine,
_b_u_n_z_i_p_2 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.

_b_z_i_p_2 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.
_b_z_i_p_2_r_e_c_o_v_e_r 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 _b_z_i_p_2 −t to test
the integrity of the resulting files, and decompress those
which are undamaged.
_b_z_i_p_2_r_e_c_o_v_e_r 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.
_b_z_i_p_2_r_e_c_o_v_e_r 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.
PPEERRFFOORRMMAANNCCEE NNOOTTEESS
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.
_b_z_i_p_2 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 _b_z_i_p_2 will per­
form best on machines with very large caches.
CCAAVVEEAATTSS
I/O error messages are not as helpful as they could be.
_b_z_i_p_2 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 1.0.8 of _b_z_i_p_2_. 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 above, 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.
_b_z_i_p_2_r_e_c_o_v_e_r 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.

NAME
bzip2, bunzip2 - a block-sorting file compressor, v1.0.8
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 1.0.8 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 above, 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

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

.TH BZMORE 1
.SH NAME
bzmore, bzless \- file perusal filter for crt viewing of bzip2 compressed text
.SH SYNOPSIS
.B bzmore
[ name ... ]
.br
.B bzless
[ name ... ]
.SH NOTE
In the following description,
.I bzless
and
.I less
can be used interchangeably with
.I bzmore
and
.I more.
.SH DESCRIPTION
.I Bzmore
is a filter which allows examination of compressed or plain text files
one screenful at a time on a soft-copy terminal.
.I bzmore
works on files compressed with
.I bzip2
and also on uncompressed files.
If a file does not exist,
.I bzmore
looks for a file of the same name with the addition of a .bz2 suffix.
.PP
.I Bzmore
normally pauses after each screenful, printing --More--
at the bottom of the screen.
If the user then types a carriage return, one more line is displayed.
If the user hits a space,
another screenful is displayed. Other possibilities are enumerated later.
.PP
.I Bzmore
looks in the file
.I /etc/termcap
to determine terminal characteristics,
and to determine the default window size.
On a terminal capable of displaying 24 lines,
the default window size is 22 lines.
Other sequences which may be typed when
.I bzmore
pauses, and their effects, are as follows (\fIi\fP is an optional integer
argument, defaulting to 1) :
.PP
.IP \fIi\|\fP<space>
display
.I i
more lines, (or another screenful if no argument is given)
.PP
.IP ^D
display 11 more lines (a ``scroll'').
If
.I i
is given, then the scroll size is set to \fIi\|\fP.
.PP
.IP d
same as ^D (control-D)
.PP
.IP \fIi\|\fPz
same as typing a space except that \fIi\|\fP, if present, becomes the new
window size. Note that the window size reverts back to the default at the
end of the current file.
.PP
.IP \fIi\|\fPs
skip \fIi\|\fP lines and print a screenful of lines
.PP
.IP \fIi\|\fPf
skip \fIi\fP screenfuls and print a screenful of lines
.PP
.IP "q or Q"
quit reading the current file; go on to the next (if any)
.PP
.IP "e or q"
When the prompt --More--(Next file:
.IR file )
is printed, this command causes bzmore to exit.
.PP
.IP s
When the prompt --More--(Next file:
.IR file )
is printed, this command causes bzmore to skip the next file and continue.
.PP
.IP =
Display the current line number.
.PP
.IP \fIi\|\fP/expr
search for the \fIi\|\fP-th occurrence of the regular expression \fIexpr.\fP
If the pattern is not found,
.I bzmore
goes on to the next file (if any).
Otherwise, a screenful is displayed, starting two lines before the place
where the expression was found.
The user's erase and kill characters may be used to edit the regular
expression.
Erasing back past the first column cancels the search command.
.PP
.IP \fIi\|\fPn
search for the \fIi\|\fP-th occurrence of the last regular expression entered.
.PP
.IP !command
invoke a shell with \fIcommand\|\fP.
The character `!' in "command" are replaced with the
previous shell command. The sequence "\\!" is replaced by "!".
.PP
.IP ":q or :Q"
quit reading the current file; go on to the next (if any)
(same as q or Q).
.PP
.IP .
(dot) repeat the previous command.
.PP
The commands take effect immediately, i.e., it is not necessary to
type a carriage return.
Up to the time when the command character itself is given,
the user may hit the line kill character to cancel the numerical
argument being formed.
In addition, the user may hit the erase character to redisplay the
--More-- message.
.PP
At any time when output is being sent to the terminal, the user can
hit the quit key (normally control\-\\).
.I Bzmore
will stop sending output, and will display the usual --More--
prompt.
The user may then enter one of the above commands in the normal manner.
Unfortunately, some output is lost when this is done, due to the
fact that any characters waiting in the terminal's output queue
are flushed when the quit signal occurs.
.PP
The terminal is set to
.I noecho
mode by this program so that the output can be continuous.
What you type will thus not show on your terminal, except for the / and !
commands.
.PP
If the standard output is not a teletype, then
.I bzmore
acts just like
.I bzcat,
except that a header is printed before each file.

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,
which is extremely unlikely. In version 1.0.3 maxLen was
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
produced by versions pre-1.0.3, the decompressor must still
handle lengths of up to 20. */

If you got this far and the 'cmp's didn't complain, it looks
like you're in business.
To install in /usr/local/bin, /usr/local/lib, /usr/local/man and
/usr/local/include, type
make install
To install somewhere else, eg, /xxx/yyy/{bin,lib,man,include}, type
make install PREFIX=/xxx/yyy
If you are (justifiably) paranoid and want to see what 'make install'
is going to do, you can first do
make -n install or
make -n install PREFIX=/xxx/yyy respectively.
The -n instructs make to show the commands it would execute, but
not actually execute them.
Instructions for use are in the preformatted manual page, in the file
bzip2.txt. For more detailed documentation, read the full manual.
It is available in Postscript form (manual.ps), PDF form (manual.pdf),
and HTML form (manual.html).
You can also do "bzip2 --help" to see some helpful information.

0.17 (up to commit 077661f, 2023-08-08)
========================================
Deprecated and removed features:
--------------------------------
* None
New features
------------
* json_patch: add first implementation only with patch application
* Add --disable-static and --disable-dynamic options to the cmake-configure script.
* Add -DBUILD_APPS=NO option to disable app build
* Minimum cmake version is now 3.9
Significant changes and bug fixes
---------------------------------
* When serializing with JSON_C_TO_STRING_PRETTY set, keep the opening and
closing curly or square braces on same line for empty objects or arrays.
* Disable locale handling when targeting a uClibc system due to problems
with its duplocale() function.
* When parsing with JSON_TOKENER_STRICT set, integer overflow/underflow
now result in a json_tokener_error_parse_number. Without that flag
values are capped at INT64_MIN/UINT64_MAX.
* Fix memory leak with emtpy strings in json_object_set_string
* json_object_from_fd_ex: fail if file is too large (>=INT_MAX bytes)
* Add back json_number_chars, but only because it's part of the public API.
* Entirely drop mode bits from open(O_RDONLY) to avoid warnings on certain
platforms.
* Specify dependent libraries, including -lbsd, in a more consistent way so
linking against a static json-c works better
* Fix a variety of build problems and add & improve tests
* Update RFC reference to https://www.rfc-editor.org/rfc/rfc8259
***
0.16 (up to commit 66dcdf5, 2022-04-13)
========================================
Deprecated and removed features:
--------------------------------
* JSON_C_OBJECT_KEY_IS_CONSTANT is deprecated in favor of
JSON_C_OBJECT_ADD_CONSTANT_KEY
* Direct access to lh_table and lh_entry structure members is deprecated.
Use access functions instead, lh_table_head(), lh_entry_next(), etc...
* Drop REFCOUNT_DEBUG code.
New features
------------
* The 0.16 release introduces no new features
Build changes
-------------
* Add a DISABLE_EXTRA_LIBS option to skip using libbsd
* Add a DISABLE_JSON_POINTER option to skip compiling in json_pointer support.
Significant changes and bug fixes
---------------------------------
* Cap string length at INT_MAX to avoid various issues with very long strings.
* json_object_deep_copy: fix deep copy of strings containing '\0'
* Fix read past end of buffer in the "json_parse" command
* Avoid out of memory accesses in the locally provided vasprintf() function
(for those platforms that use it)
* Handle allocation failure in json_tokener_new_ex
* Fix use-after-free in json_tokener_new_ex() in the event of printbuf_new() returning NULL
* printbuf_memset(): set gaps to zero - areas within the print buffer which
have not been initialized by using printbuf_memset
* printbuf: return -1 on invalid arguments (len < 0 or total buffer > INT_MAX)
* sprintbuf(): propagate printbuf_memappend errors back to the caller
Optimizations
--------------
* Speed up parsing by replacing ctype functions with simplified, faster
non-locale-sensitive ones in json_tokener and json_object_to_json_string.
* Neither vertical tab nor formfeed are considered whitespace per the JSON spec
* json_object: speed up creation of objects, calloc() -> malloc() + set fields
* Avoid needless extra strlen() call in json_c_shallow_copy_default() and
json_object_equal() when the object is known to be a json_type_string.
Other changes
-------------
* Validate size arguments in arraylist functions.
* Use getrandom() if available; with GRND_NONBLOCK to allow use of json-c
very early during boot, such as part of cryptsetup.
* Use arc4random() if it's available.
* random_seed: on error, continue to next method instead of exiting the process
* Close file when unable to read from /dev/urandom in get_dev_random_seed()
***
0.15 (up to commit 870965e, 2020/07/26)
========================================
Deprecated and removed features:
--------------------------------
* Deprecate `array_list_new()` in favor of `array_list_new2()`
* Remove the THIS_FUNCTION_IS_DEPRECATED define.
* Remove config.h.win32
New features
------------
* Add a `JSON_TOKENER_ALLOW_TRAILING_CHARS` flag to allow multiple objects
to be parsed even when `JSON_TOKENER_STRICT` is set.
* Add `json_object_new_array_ext(int)` and `array_list_new_2(int)` to allow
arrays to be allocated with the exact size needed, when known.
* Add `json_object_array_shrink()` (and `array_list_shrink()`) and use it in
json_tokener to minimize the amount of memory used.
* Add a json_parse binary, for use in testing changes (not installed, but
available in the apps directory).
Build changes
-------------
* #639/#621 - Add symbol versions to all exported symbols
* #508/#634 - Always enable -fPIC to allow use of the json-c static library in
other libraries
* Build both static and shared libraries at the same time.
* #626 - Restore compatibility with cmake 2.8
* #471 - Always create directories with mode 0755, regardless of umask.
* #606/#604 - Improve support for OSes like AIX and IBM i, as well as for
MINGW32 and old versions of MSVC
* #451/#617 - Add a DISABLE_THREAD_LOCAL_STORAGE cmake option to disable
the use of thread-local storage.
Significant changes and bug fixes
---------------------------------
* Split the internal json_object structure into several sub-types, one for
each json_type (json_object_object, json_object_string, etc...).
This improves memory usage and speed, with the benchmark under
bench/ report 5.8% faster test time and 6%(max RSS)-12%(peak heap)
less memory usage.
Memory used just for json_object structures decreased 27%, so use cases
with fewer arrays and/or strings would benefit more.
* Minimize memory usage in array handling in json_tokener by shrinking
arrays to the exact number of elements parsed. On bench/ benchmark:
9% faster test time, 39%(max RSS)-50%(peak heap) less memory usage.
Add json_object_array_shrink() and array_list_shrink() functions.
* #616 - Parsing of surrogate pairs in unicode escapes now properly handles
incremental parsing.
* Fix incremental parsing of numbers, especially those with exponents, e.g.
so parsing "[0", "e+", "-]" now properly returns an error.
Strict mode now rejects missing exponents ("0e").
* Successfully return number objects at the top level even when they are
followed by a "-", "." or "e". This makes parsing things like "123-45"
behave consistently with things like "123xyz".
Other changes
-------------
* #589 - Detect broken RDRAND during initialization; also, fix segfault
in the CPUID check.
* #592 - Fix integer overflows to prevert out of bounds write on large input.
* Protect against division by zero in linkhash, when created with zero size.
* #602 - Fix json_parse_uint64() internal error checking, leaving the retval
untouched in more failure cases.
* #614 - Prevent truncation when custom double formatters insert extra \0's

0.14 (up to commit 9ed00a6, 2020/04/14)
=========================================
Deprecated and removed features:
--------------------------------
* bits.h has been removed
* lh_abort() has been removed
* lh_table_lookup() has been removed, use lh_table_lookup_ex() instead.
* Remove TRUE and FALSE defines, use 1 and 0 instead.
Build changes:
--------------
## Deprecated and removed features:
* bits.h has been removed
* lh_abort() has been removed
* lh_table_lookup() has been removed, use lh_table_lookup_ex() instead.
* Remove TRUE and FALSE defines, use 1 and 0 instead.
* autoconf support, including autogen.sh, has been removed. See details about cmake, below.
* With the addition of json_tokener_get_parse_end(), access to internal fields of json_tokener, as well as use of many other symbols and types in json_tokener.h, is deprecated now.
* The use of Android.configure.mk to build for Android no longer works, and it is unknown how (or if) the new cmake-based build machinery can be used.
* Reports of success, or pull requests to correct issues are welcome.
## Notable improvements and new features
### Builds and documentation
* Build machinery has been switched to CMake. See README.md for details about how to build.
* TL;DR: `mkdir build ; cd build ; cmake -DCMAKE_INSTALL_PREFIX=/some/path ../json-c ; make all test install`
* To ease the transition, there is a `cmake-configure` wrapper that emulates the old autoconf-based configure script.
* This has enabled improvements to the build on Windows system; also all public functions have been fixed to be properly exported. For best results, use Visual Studio 2015 or newer.
* The json-c style guide has been updated to specify the use of clang-format, and all code has been reformatted.
* Since many lines of code have trivial changes now, when using git blame, be sure to specify -w
* Numerous improvements have been made to the documentation including function effects on refcounts, when passing a NULL is safe, and so on.
### json_tokener changes
* Added a json_tokener_get_parse_end() function to replace direct access of tok->char_offset.
* The char_offset field, and the rest of the json_tokener structure remain exposed for now, but expect a future release to hide it like is done with json_object_private.h
* json_tokener_parse_ex() now accepts a new JSON_TOKENER_VALIDATE_UTF8 flag to validate that input is UTF8.
* If validation fails, json_tokener_get_error(tok) will return json_tokener_error_parse_utf8_string (see enum json_tokener_error).
### Other changes and additions
* Add support for unsigned 64-bit integers, uint64_t, to gain one extra bit of magnitude for positive ints.
* json_tokener will now parse values up to UINT64_MAX (18446744073709551615)
* Existing methods returning int32_t or int64_t will cap out-of-range values at INT32_MAX or INT64_MAX, preserving existing behavior.
* The implementation includes the possibility of easily extending this to larger sizes in the future.
* A total of 7 new functions were added:
* json_object_get_uint64 ( struct json_object const* jso )
* json_object_new_uint64 ( uint64_t i )
* json_object_set_uint64 ( struct json_object* jso, uint64_t new_value )
* json_parse_uint64 ( char const* buf, uint64_t* retval )
* See description of uint64 support, above.
* json_tokener_get_parse_end ( struct json_tokener* tok )
* See details under "json_tokener changes", above.
* json_object_from_fd_ex ( int fd, int in_depth )
* Allows the max nesting depth to be specified.
* json_object_new_null ( )
* Simply returns NULL. Its use is not recommended.
* The size of struct json_object has decreased from 96 bytes to 88 bytes.
### Testing
* Many updates were made to test cases, increasing code coverage.
* There is now a quick way (JSONC_TEST_TRACE=1) to turn on shell tracing in tests.
* To run tests, use `make test`; the old "check" target no longer exists.
## Significant bug fixes
For the full list of issues and pull requests since the previous release, please see issues_closed_for_0.14.md
* [Issue #389](https://github.com/json-c/json-c/issues/389): Add an assert to explicitly crash when _ref_count is corrupted, instead of a later "double free" error.
* [Issue #407](https://github.com/json-c/json-c/issues/407): fix incorrect casts in calls to ctype functions (isdigit and isspace) so we don't crash when asserts are enabled on certain platforms and characters > 128 are parsed.
* [Issue #418](https://github.com/json-c/json-c/issues/418): Fix docs for json_util_from_fd and json_util_from_file to say that they return NULL on failures.
* [Issue #422](https://github.com/json-c/json-c/issues/422): json_object.c:set errno in json_object_get_double() when called on a json_type_string object with bad content.
* [Issue #453](https://github.com/json-c/json-c/issues/453): Fixed misalignment in JSON serialization when JSON_C_TO_STRING_SPACED and JSON_C_TO_STRING_PRETTY are used together.
* [Issue #463](https://github.com/json-c/json-c/issues/463): fix newlocale() call to use LC_NUMERIC_MASK instead of LC_NUMERIC, and remove incorrect comment.
* [Issue #486](https://github.com/json-c/json-c/issues/486): append a missing ".0" to negative double values to ensure they are serialized as floating point numbers.
* [Issue #488](https://github.com/json-c/json-c/issues/488): use JSON_EXPORT on functions so they are properly exported on Windows.
* [Issue #539](https://github.com/json-c/json-c/issues/539): use an internal-only serializer function in json_object_new_double_s() to avoid potential conflicts with user code that uses the json_object_userdata_to_json_string serializer.
***
0.13.1 (up to commit 0f814e5, 2018/03/04)
=========================================
* Bump the major version of the .so library generated up to 4.0 to avoid
conflicts because some downstream packagers of json-c had already done
their own bump to ".so.3" for a much older 0.12 release.
* Add const size_t json_c_object_sizeof()
* Avoid invalid free (and thus a segfault) when ref_count gets < 0
* PR#394: fix handling of custom double formats that include a ".0"
* Avoid uninitialized variable warnings in json_object_object_foreach
* Issue #396: fix build for certain uClibc based systems.
* Add a top level fuzz directory for fuzzers run by OSS-Fuzz
0.13 (up to commit 5dae561, 2017/11/29)
=================================
This release, being three and a half years after the 0.12 branch (f84d9c),
has quite a number of changes included. The following is a sampling of
the most significant ones.
Since the 0.12 release, 250 issues and pull requests have been closed.
See issues_closed_for_0.13.md for a complete list.
Deprecated and removed features:
--------------------------------
* All internal use of bits.h has been eliminated. The file will be removed.
Do not use: hexdigit(), error_ptr(), error_descrition() and it_error()
* lh_abort() is deprecated. It will be removed.
Behavior changes:
-----------------
* Tighten the number parsing algorithm to raise errors instead of truncating
the results. For example 12.3.4 or 2015-01-15, which now return null.
See commit 99d8fc
* Use size_t for array length and size. Platforms where sizeof(size_t) != sizeof(int) may not be backwards compatible
See commits 45c56b, 92e9a5 and others.
* Check for failure when allocating memory, returning NULL and errno=ENOMEM.
See commit 2149a04.
* Change json_object_object_add() return type from void to int, and will return -1 on failures, instead of exiting. (Note: this is not an ABI change)
New features:
-------------
* We're aiming to follow RFC 7159 now.
* Add a couple of additional option to json_object_to_json_string_ext:
JSON_C_TO_STRING_PRETTY_TAB
JSON_C_TO_STRING_NOSLASHESCAPE
* Add a json_object_object_add_ex() function to allow for performance
improvements when certain constraints are known to be true.
* Make serialization format of doubles configurable, in two different ways:
Call json_object_set_serializer with json_object_double_to_json_string and a custom
format on each double object, or
Call json_c_set_serialization_double_format() to set a global or thread-wide format.
* Add utility function for comparing json_objects - json_object_equal()
* Add a way to copy entire object trees: json_object_deep_copy()
* Add json_object_set_<type> function to modify the value of existing json_object's
without the need to recreate them. Also add a json_object_int_inc function to
adjust an int's value.
* Add support for JSON pointer, RFC 6901. See json_pointer.h
* Add a json_util_get_last_err() function to retrieve the string describing the
cause of errors, instead of printing to stderr.
* Add perllike hash function for strings, and json_global_set_string_hash() 8f8d03d
* Add a json_c_visit() function to provide a way to iterate over a tree of json-c objects.
Notable bug fixes and other improvements:
-----------------------------------------
* Make reference increment and decrement atomic to allow passing json objects between threads.
* Fix json_object_object_foreach to avoid uninitialized variable warnings.
* Improve performance by removing unneeded data items from hashtable code and reducing duplicate hash computation.
* Improve performance by storing small strings inside json_object
* Improve performance of json_object_to_json_string by removing variadic printf. commit 9ff0f49
* Issue #371: fix parsing of "-Infinity", and avoid needlessly copying the input when doing so.
* Fix stack buffer overflow in json_object_double_to_json_string_format() - commit 2c2deb87
* Fix various potential null ptr deref and int32 overflows
* Issue #332: fix a long-standing bug in array_list_put_idx() where it would attempt to free previously free'd entries due to not checking the current array length.
* Issue #195: use uselocale() instead of setlocale() in json_tokener to behave better in threaded environments.
* Issue #275: fix out of bounds read when handling unicode surrogate pairs.
* Ensure doubles that happen to be a whole number are emitted with ".0" - commit ca7a19
* PR#331: for Visual Studio, use a snprintf/vsnprintf wrapper that ensures the string is terminated.
* Fix double to int cast overflow in json_object_get_int64.
* Clamp double to int32 when narrowing in json_object_get_int.
* Use strtoll() to parse ints - instead of sscanf
* Miscellaneous smaller changes, including removing unused variables, fixing warning
about uninitialized variables adding const qualifiers, reformatting code, etc...
Build changes:
--------------
* Add Appveyor and Travis build support
* Switch to using CMake when building on Windows with Visual Studio.
A dynamic .dll is generated instead of a .lib
config.h is now generated, config.h.win32 should no longer be manually copied
* Add support for MacOS through CMake too.
* Enable silent build by default
* Link against libm when needed
* Add support for building with AddressSanitizer

0.12.1
======
* Minimal changes to address compile issues.
0.12
====
* Address security issues:
* CVE-2013-6371: hash collision denial of service
* CVE-2013-6370: buffer overflow if size_t is larger than int
* Avoid potential overflow in json_object_get_double
* Eliminate the mc_abort() function and MC_ABORT macro.
* Make the json_tokener_errors array local. It has been deprecated for
a while, and json_tokener_error_desc() should be used instead.
* change the floating point output format to %.17g so values with
more than 6 digits show up in the output.
* Remove the old libjson.so name compatibility support. The library is
only created as libjson-c.so now and headers are only installed
into the ${prefix}/json-c directory.
* When supported by the linker, add the -Bsymbolic-functions flag.
* Various changes to fix the build on MSVC.
* Make strict mode more strict:
* number must not start with 0
* no single-quote strings
* no comments
* trailing char not allowed
* only allow lowercase literals
* Added a json_object_new_double_s() convenience function to allow
an exact string representation of a double to be specified when
creating the object and use it in json_tokener_parse_ex() so
a re-serialized object more exactly matches the input.
* Add support NaN and Infinity
0.11
====
* IMPORTANT: the name of the library has changed to libjson-c.so and
the header files are now in include/json-c.
The pkgconfig name has also changed from json to json-c.
You should change your build to use appropriate -I and -l options.
A compatibility shim is in place so builds using the old name will
continue to work, but that will be removed in the next release.
* Maximum recursion depth is now a runtime option.
json_tokener_new() is provided for compatibility.
json_tokener_new_ex(depth)
* Include json_object_iterator.h in the installed headers.
* Add support for building on Android.
* Rewrite json_object_object_add to replace just the value if the key already exists so keys remain valid.
* Make it safe to delete keys while iterating with the json_object_object_foreach macro.
* Add a json_set_serializer() function to allow the string output of a json_object to be customized.
* Make float parsing locale independent.
* Add a json_tokener_set_flags() function and a JSON_TOKENER_STRICT flag.
* Enable -Werror when building.
* speed improvements to parsing 64-bit integers on systems with working sscanf
* Add a json_object_object_length function.
* Fix a bug (buffer overrun) when expanding arrays to more than 64 entries.
0.10
====
* Add a json_object_to_json_string_ext() function to allow output to be
formatted in a more human readable form.
* Add json_object_object_get_ex(), a NULL-safe get object method, to be able
to distinguish between a key not present and the value being NULL.
* Add an alternative iterator implementation, see json_object_iterator.h
* Make json_object_iter public to enable external use of the
json_object_object_foreachC macro.
* Add a printbuf_memset() function to provide an efficient way to set and
append things like whitespace indentation.
* Adjust json_object_is_type and json_object_get_type so they return
json_type_null for NULL objects and handle NULL passed to
json_objct_object_get().
* Rename boolean type to json_bool.
* Fix various compile issues for Visual Studio and MinGW.
* Allow json_tokener_parse_ex() to be re-used to parse multiple object.
Also, fix some parsing issues with capitalized hexadecimal numbers and
number in E notation.
* Add json_tokener_get_error() and json_tokener_error_desc() to better
encapsulate the process of retrieving errors while parsing.
* Various improvements to the documentation of many functions.
* Add new json_object_array_sort() function.
* Fix a bug in json_object_get_int(), which would incorrectly return 0
when called on a string type object.
Eric Haszlakiewicz
* Add a json_type_to_name() function.
Eric Haszlakiewicz
* Add a json_tokener_parse_verbose() function.
Jehiah Czebotar
* Improve support for null bytes within JSON strings.
Jehiah Czebotar
* Fix file descriptor leak if memory allocation fails in json_util
Zachary Blair, zack_blair at hotmail dot com

### Prerequisites: <a name="installprereq"></a>
- `gcc`, `clang`, or another C compiler
- `cmake>=2.8`, `>=3.16` recommended, `cmake=>3.1` for tests
To generate docs you'll also need:
- `doxygen>=1.8.13`
If you are on a relatively modern system, you'll likely be able to install
the prerequisites using your OS's packaging system.
### Install using apt (e.g. Ubuntu 16.04.2 LTS)
```sh
sudo apt install git
sudo apt install cmake
sudo apt install doxygen # optional
sudo apt install valgrind # optional
```
### Build instructions: <a name="buildcmds"></a>
`json-c` GitHub repo: https://github.com/json-c/json-c
```sh
$ git clone https://github.com/json-c/json-c.git
$ mkdir json-c-build
$ cd json-c-build
$ cmake ../json-c # See CMake section below for custom arguments
```
Note: it's also possible to put your build directory inside the json-c
source directory, or even not use a separate build directory at all, but
certain things might not work quite right (notably, `make distcheck`)
Then:
```sh
$ make
$ make test
$ make USE_VALGRIND=0 test # optionally skip using valgrind
$ sudo make install # it could be necessary to execute make install
```
### Generating documentation with Doxygen:
The library documentation can be generated directly from the source code using Doxygen tool:
```sh
# in build directory
make doc
google-chrome doc/html/index.html
```
CMake Options <a name="CMake"></a>
--------------------
The json-c library is built with [CMake](https://cmake.org/cmake-tutorial/),
which can take a few options.
Variable | Type | Description
-----------------------------|--------|--------------
CMAKE_INSTALL_PREFIX | String | The install location.
CMAKE_BUILD_TYPE | String | Defaults to "debug".
BUILD_SHARED_LIBS | Bool | The default build generates a dynamic (dll/so) library. Set this to OFF to create a static library only.
BUILD_STATIC_LIBS | Bool | The default build generates a static (lib/a) library. Set this to OFF to create a shared library only.
DISABLE_STATIC_FPIC | Bool | The default builds position independent code. Set this to OFF to create a shared library only.
DISABLE_BSYMBOLIC | Bool | Disable use of -Bsymbolic-functions.
DISABLE_THREAD_LOCAL_STORAGE | Bool | Disable use of Thread-Local Storage (HAVE___THREAD).
DISABLE_WERROR | Bool | Disable use of -Werror.
DISABLE_EXTRA_LIBS | Bool | Disable use of extra libraries, libbsd
DISABLE_JSON_POINTER | Bool | Omit json_pointer support from the build.
ENABLE_RDRAND | Bool | Enable RDRAND Hardware RNG Hash Seed.
ENABLE_THREADING | Bool | Enable partial threading support.
OVERRIDE_GET_RANDOM_SEED | String | A block of code to use instead of the default implementation of json_c_get_random_seed(), e.g. on embedded platforms where not even the fallback to time() works. Must be a single line.
Pass these options as `-D` on CMake's command-line.
```sh
# build a static library only
cmake -DBUILD_SHARED_LIBS=OFF ..
```
### Building with partial threading support
Although json-c does not support fully multi-threaded access to
object trees, it has some code to help make its use in threaded programs
a bit safer. Currently, this is limited to using atomic operations for
json_object_get() and json_object_put().
Since this may have a performance impact, of at least 3x slower
according to https://stackoverflow.com/a/11609063, it is disabled by
default. You may turn it on by adjusting your cmake command with:
-DENABLE_THREADING=ON
Separately, the default hash function used for object field keys,
lh_char_hash, uses a compare-and-swap operation to ensure the random
seed is only generated once. Because this is a one-time operation, it
is always compiled in when the compare-and-swap operation is available.
### cmake-configure wrapper script
For those familiar with the old autoconf/autogen.sh/configure method,
there is a `cmake-configure` wrapper script to ease the transition to cmake.
```sh
mkdir build
cd build
../cmake-configure --prefix=/some/install/path
make
```
cmake-configure can take a few options.
| options | Description|
| ---- | ---- |
| prefix=PREFIX | install architecture-independent files in PREFIX |
| enable-threading | Enable code to support partly multi-threaded use |
| enable-rdrand | Enable RDRAND Hardware RNG Hash Seed generation on supported x86/x64 platforms. |
| enable-shared | build shared libraries [default=yes] |
| enable-static | build static libraries [default=yes] |
| disable-Bsymbolic | Avoid linking with -Bsymbolic-function |
| disable-werror | Avoid treating compiler warnings as fatal errors |
Testing: <a name="testing"></a>
----------
By default, if valgrind is available running tests uses it.
That can slow the tests down considerably, so to disable it use:
```sh
export USE_VALGRIND=0
```
To run tests a separate build directory is recommended:
```sh
mkdir build-test
cd build-test
# VALGRIND=1 causes -DVALGRIND=1 to be passed when compiling code
# which uses slightly slower, but valgrind-safe code.
VALGRIND=1 cmake ..
make
make test
# By default, if valgrind is available running tests uses it.
make USE_VALGRIND=0 test # optionally skip using valgrind
```
If a test fails, check `Testing/Temporary/LastTest.log`,
`tests/testSubDir/${testname}/${testname}.vg.out`, and other similar files.
If there is insufficient output try:
```sh
VERBOSE=1 CTEST_OUTPUT_ON_FAILURE=1 make test
```
or
```sh
JSONC_TEST_TRACE=1 make test
```
and check the log files again.
Building on Unix and Windows with `vcpkg` <a name="buildvcpkg"></a>
--------------------------------------------------
You can download and install JSON-C using the [vcpkg](https://github.com/Microsoft/vcpkg/) dependency manager:
git clone https://github.com/Microsoft/vcpkg.git
cd vcpkg
./bootstrap-vcpkg.sh
./vcpkg integrate install
vcpkg install json-c
The JSON-C port in vcpkg is kept up to date by Microsoft team members and community contributors. If the version is out of date, please [create an issue or pull request](https://github.com/Microsoft/vcpkg) on the vcpkg repository.
Building for Android <a name="android">
----------------------
Building on Android is now particularly well supported, but there
have been some reports of success using
https://developer.android.com/ndk/guides/cmake
```
mkdir json-c-build
cd json-c-build/

Linking to `libjson-c` <a name="linking">
----------------------
If your system has `pkgconfig`,
then you can just add this to your `makefile`:
```make
CFLAGS += $(shell pkg-config --cflags json-c)
LDFLAGS += $(shell pkg-config --libs json-c)
```
Without `pkgconfig`, you might do something like this:
```make
JSON_C_DIR=/path/to/json_c/install
CFLAGS += -I$(JSON_C_DIR)/include/json-c
# Or to use lines like: #include <json-c/json_object.h>
#CFLAGS += -I$(JSON_C_DIR)/include
LDFLAGS+= -L$(JSON_C_DIR)/lib -ljson-c
```
If your project uses cmake:
* Add to your CMakeLists.txt file:
```cmake
find_package(json-c CONFIG)
target_link_libraries(${PROJECT_NAME} PRIVATE json-c::json-c)
```
* Then you might run in your project:
```sh
cd build
cmake -DCMAKE_PREFIX_PATH=/path/to/json_c/install/lib64/cmake ..
```
Using json-c <a name="using">
------------
To use json-c you can either include json.h, or preferably, one of the
following more specific header files:
* json_object.h - Core types and methods.
* json_tokener.h - Methods for parsing and serializing json-c object trees.
* json_pointer.h - JSON Pointer (RFC 6901) implementation for retrieving
objects from a json-c object tree.
* json_object_iterator.h - Methods for iterating over single json_object instances. (See also `json_object_object_foreach()` in json_object.h)
* json_visit.h - Methods for walking a tree of json-c objects.
* json_util.h - Miscellaneous utility functions.
For a full list of headers see [files.html](https://json-c.github.io/json-c/json-c-current-release/doc/html/files.html)
The primary type in json-c is json_object. It describes a reference counted
tree of json objects which are created by either parsing text with a
json_tokener (i.e. `json_tokener_parse_ex()`), or by creating
(with `json_object_new_object()`, `json_object_new_int()`, etc...) and adding
(with `json_object_object_add()`, `json_object_array_add()`, etc...) them
individually.
Typically, every object in the tree will have one reference, from its parent.
When you are done with the tree of objects, you call json_object_put() on just
the root object to free it, which recurses down through any child objects
calling json_object_put() on each one of those in turn.
You can get a reference to a single child
(`json_object_object_get()` or `json_object_array_get_idx()`)
and use that object as long as its parent is valid.
If you need a child object to live longer than its parent, you can
increment the child's refcount (`json_object_get()`) to allow it to survive
the parent being freed or it being removed from its parent
(`json_object_object_del()` or `json_object_array_del_idx()`)
When parsing text, the json_tokener object is independent from the json_object
that it returns. It can be allocated (`json_tokener_new()`)
used one or multiple times (`json_tokener_parse_ex()`, and
freed (`json_tokener_free()`) while the json_object objects live on.
A json_object tree can be serialized back into a string with
`json_object_to_json_string_ext()`. The string that is returned
is only valid until the next "to_json_string" call on that same object.
Also, it is freed when the json_object is freed.

# Release checklist:
## Pre-release tasks
* Figure out whether a release is worthwhile to do.
* Analyze the previous release branch to see if anything should have been
applied to master.
* Collect changes and assemble tentative release notes.
* Identify previous release branch point
* Check commit logs between previous branch point and now for
notable changes worth mentioning
* Create a new issues_closed_for_X.Y.md file
* Include notable entries from here in the release notes.
* Analyze APIs between previous release branch and master to produce list of
changes (added/removed/updated funcs, etc...), and detect backwards compat
issues.
* https://github.com/lvc/abi-compliance-checker
* See also `abi-check.sh`
* If the new release is not backwards compatible, then this is a MAJOR release.
* Mention removed features in ChangeLog
* Consider re-adding backwards compatible support, through symbol
aliases and appropriate entries in json-c.sym
* Be sure any new symbols are listed in json-c.sym as part of
the _new_ release version.
* Update the AUTHORS file
PREV=$(git tag | tail -1)
( git log -r ${PREV}..HEAD | grep Author: | sed -e's/Author: //' ; cat AUTHORS ) | sort -u > A1
mv A1 AUTHORS
* Exclude mentioning changes that have already been included in a point
release of the previous release branch.
* Update ChangeLog with relevant notes before branching.
* Check that the compile works on Linux - automatic through Travis
* Check that the compile works on NetBSD
* Check that the compile works on Windows - automatic through AppVeyor
## Release creation
Start creating the new release:
PREV=$(git tag | tail -1)
PREV=${PREV#json-c-}
PREV=${PREV%-*}
release=0.$((${PREV#*.} + 1))
cd ~
git clone https://github.com/json-c/json-c json-c-${release}
rm -rf distcheck
mkdir distcheck
cd distcheck
# Note, the build directory *must* be entirely separate from
# the source tree for distcheck to work properly.
cmake -DCMAKE_BUILD_TYPE=Release ../json-c-${release}
make distcheck
cd ..
Make any fixes/changes *before* branching.
cd json-c-${release}
git checkout -b json-c-${release}
------------
Using ${release}:
Update the version in json_c_version.h
Update the version in CMakeLists.txt (VERSION in the project(...) line)
Update the set_target_properties() line in CmakeLists.txt to set the shared
library version. Generally, unless we're doing a major release, change:
VERSION x.y.z
to
VERSION x.y+1.z
git commit -a -m "Bump version to ${release}"
If we're doing a major release (SONAME bump), also bump the version
of ALL symbols in json-c.sym.
See explanation at https://github.com/json-c/json-c/issues/621
More info at: https://software.intel.com/sites/default/files/m/a/1/e/dsohowto.pdf
------------
Generate the doxygen documentation:
(cd ../distcheck && make doc)
cp -r -p ../distcheck/doc/{html,Doxyfile} doc/.
rm doc/Doxyfile # Remove generated file w/ hardcoded paths
git add -f doc
git commit doc -m "Generate docs for the ${release} release"
------------
Create the release tarballs:
cd ..
echo .git > excludes
tar -czf json-c-${release}.tar.gz -X excludes json-c-${release}
echo 'doc/*.cmake' >> excludes
echo 'doc/CMakeFiles' >> excludes
echo 'doc/Makefile' >> excludes
echo 'doc/Doxyfile' >> excludes
echo 'doc/html' >> excludes
tar -czf json-c-${release}-nodoc.tar.gz -X excludes json-c-${release}
------------
Tag the branch:
cd json-c-${release}
git tag -a json-c-${release}-$(date +%Y%m%d) -m "Release json-c-${release}"
git push origin json-c-${release}
git push --tags
------------
Go to Amazon S3 service at:
https://console.aws.amazon.com/s3/
Upload the two tarballs in the json-c_releases/releases folder.
* Expand "Permissions", pick "Grant public-read access"
* Expand "Properties", ensure "Standard" storage class is picked.
Logout of Amazon S3, and verify that the files are visible.
https://s3.amazonaws.com/json-c_releases/releases/index.html
===================================
Post-release checklist:
git checkout master
Add new section to ChangeLog for ${release}+1
Use ${release}.99 to indicate a version "newer" than anything on the branch:
Update the version in json_c_version.h
Update the version in CMakeLists.txt
Update RELEASE_CHECKLIST.txt, set release=${release}+1
Add a new empty section to the json-c.sym file, for ${release}+1
Update the set_target_properties() line in CmakeLists.txt to match the release branch.
git commit -a -m "Update the master branch to version ${release}.99"
git push
------------
Update the gh-pages branch with new docs:
cd json-c-${release}
git checkout json-c-${release}
cd ..
git clone -b gh-pages https://github.com/json-c/json-c json-c-pages
cd json-c-pages
mkdir json-c-${release}
cp -R ../json-c-${release}/doc json-c-${release}/.
git add json-c-${release}
rm json-c-current-release
ln -s json-c-${release} json-c-current-release
git commit -a -m "Add the ${release} docs."
vi index.html
# Add/change links to current release.
git commit -a -m "Update the doc links to point at ${release}"
git push
------------
Update checksums on wiki page.
cd ..
openssl sha -sha256 json-c*gz
openssl md5 json-c*gz
Copy and paste this output into the wiki page at:
* https://github.com/json-c/json-c/wiki
* https://github.com/json-c/json-c/wiki/Old-Releases

View File

@ -1,31 +0,0 @@
In general:
For minor changes to a function, copy the existing formatting.
When changing the style, commit that separately from other changes.
For new code and major changes to a function, switch to the official json-c style.
Official json-c style:
Aim for readability, not strict conformance to fixed style rules.
Formatting is tab based; previous attempts at proper alignment with
spaces for continuation lines have been abandoned in favor of the
convenience of using clang-format.
Refer to the .clang-format file for details, and run the tool before commit:
clang-format -i somefile.c foo.h
For sections of code that would be significantly negatively impacted, surround
them with magic comments to disable formatting:
/* clang-format off */
...code...
/* clang-format on */
Naming:
Words within function and variable names are separated with underscores. Avoid camel case.
Prefer longer, more descriptive names, but not excessively so. No single letter variable names.
Other:
Variables should be defined for the smallest scope needed.
Functions should be defined static when possible.
When possible, avoid exposing internals in the public API.

Benchmark tests for json-c
General strategy:
-------------------
* Identify "after" commit hash
* Use provided directory
* Use provided commit hash
* Local changes in current working directory
* ${cur_branch}
* Identify "before" commit hash, in order of preference
* Use provided directory
* Use provided commit hash
* Use origin/${cur_branch}, if different from ${after_commit}
* Use previous release
* If not using existing dir, clone to src-${after_commit}
* or, checkout appropriate commit in existing src-${after_commit}
* Create build & install dirs for ${after_commit}
* Build & install ${after_commit}
* Compile benchmark programs against install-${after_commit}
* If not using existing dir, clone to src-${before_commit}
* or, checkout appropriate commit in existing src-${before_commit}
* Create build & install dirs for ${before_commit}
* Build & install ${before_commit}
* Compile benchmark programs against install-${before_commit}
* Run benchmark in each location
* Compare results
heaptrack memory profiler
---------------------------
https://milianw.de/blog/heaptrack-a-heap-memory-profiler-for-linux.html
```
yum install libdwarf-devel elfutils boost-devel libunwind-devel
git clone git://anongit.kde.org/heaptrack
cd heaptrack
mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE=RelWithDebInfo \
-DCMAKE_INSTALL_PREFIX=$HOME/heaptrack-install ..
make install
```
Issues
--------
* jc-bench.sh is incomplete.
* valgrind massif misreports "extra-heap" bytes?
"json_parse -n canada.json" shows 38640 KB maxrss.
Using valgrind --tool=massif, a large amount of memory is listed as
wasted "extra-heap" bytes. (~5.6MB)
```
valgrind --tool=massif --massif-out-file=massif.out ./json_parse -n ~/canada.json
ms_print massif.out
```
Using heaptrack, and analyzing the histogram, only shows ~2.6MB
```
heaptrack ./json_parse -n canada.json
heaptrack --analyze heaptrack*gz -H histogram.out
awk ' { s=$1; count=$2; ru=(int((s+ 15) / 16)) * 16; wasted = ((ru-s)*count); print s, count, ru-s, wasted; total=total+wasted} END { print "Total: ", total }' histogram.out
```
With the (unreleased) arraylist trimming changes, maxrss reported by
getrusage() goes down, but massif claims *more* total usage, and a HUGE
extra-heap amount (50% of total).
