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 1.0.6 of 6 September 2010

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 (http://www.bzip.org). 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.

||||

I hope you find bzip2 useful. Feel free to contact me at
|
||||
jseward@bzip.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.
