Frequently Asked Questions about zlib
|
||||
|
||||
|
||||
If your question is not there, please check the zlib home page
|
||||
http://www.zlib.org which may have more recent information.
|
||||
The lastest zlib FAQ is at http://www.gzip.org/zlib/zlib_faq.html
|
||||
|
||||
|
||||
1. Is zlib Y2K-compliant?
|
||||
|
||||
Yes. zlib doesn't handle dates.
|
||||
|
||||
2. Where can I get a Windows DLL version?
|
||||
|
||||
The zlib sources can be compiled without change to produce a DLL.
|
||||
See the file win32/DLL_FAQ.txt in the zlib distribution.
|
||||
Pointers to the precompiled DLL are found in the zlib web site at
|
||||
http://www.zlib.org.
|
||||
|
||||
3. Where can I get a Visual Basic interface to zlib?
|
||||
|
||||
See
|
||||
* http://www.dogma.net/markn/articles/zlibtool/zlibtool.htm
|
||||
* contrib/visual-basic.txt in the zlib distribution
|
||||
* win32/DLL_FAQ.txt in the zlib distribution
|
||||
|
||||
4. compress() returns Z_BUF_ERROR.
|
||||
|
||||
Make sure that before the call of compress, the length of the compressed
|
||||
buffer is equal to the total size of the compressed buffer and not
|
||||
zero. For Visual Basic, check that this parameter is passed by reference
|
||||
("as any"), not by value ("as long").
|
||||
|
||||
5. deflate() or inflate() returns Z_BUF_ERROR.
|
||||
|
||||
Before making the call, make sure that avail_in and avail_out are not
|
||||
zero. When setting the parameter flush equal to Z_FINISH, also make sure
|
||||
that avail_out is big enough to allow processing all pending input.
|
||||
Note that a Z_BUF_ERROR is not fatal--another call to deflate() or
|
||||
inflate() can be made with more input or output space. A Z_BUF_ERROR
|
||||
may in fact be unavoidable depending on how the functions are used, since
|
||||
it is not possible to tell whether or not there is more output pending
|
||||
when strm.avail_out returns with zero.
|
||||
|
||||
6. Where's the zlib documentation (man pages, etc.)?
|
||||
|
||||
It's in zlib.h for the moment, and Francis S. Lin has converted it to a
|
||||
web page zlib.html. Volunteers to transform this to Unix-style man pages,
|
||||
please contact us (zlib@gzip.org). Examples of zlib usage are in the files
|
||||
example.c and minigzip.c.
|
||||
|
||||
7. Why don't you use GNU autoconf or libtool or ...?
|
||||
|
||||
Because we would like to keep zlib as a very small and simple
|
||||
package. zlib is rather portable and doesn't need much configuration.
|
||||
|
||||
8. I found a bug in zlib.
|
||||
|
||||
Most of the time, such problems are due to an incorrect usage of
|
||||
zlib. Please try to reproduce the problem with a small program and send
|
||||
the corresponding source to us at zlib@gzip.org . Do not send
|
||||
multi-megabyte data files without prior agreement.
|
||||
|
||||
9. Why do I get "undefined reference to gzputc"?
|
||||
|
||||
If "make test" produces something like
|
||||
|
||||
example.o(.text+0x154): undefined reference to `gzputc'
|
||||
|
||||
check that you don't have old files libz.* in /usr/lib, /usr/local/lib or
|
||||
/usr/X11R6/lib. Remove any old versions, then do "make install".
|
||||
|
||||
10. I need a Delphi interface to zlib.
|
||||
|
||||
See the contrib/delphi directory in the zlib distribution.
|
||||
|
||||
11. Can zlib handle .zip archives?
|
||||
|
||||
Not by itself, no. See the directory contrib/minizip in the zlib
|
||||
distribution.
|
||||
|
||||
12. Can zlib handle .Z files?
|
||||
|
||||
No, sorry. You have to spawn an uncompress or gunzip subprocess, or adapt
|
||||
the code of uncompress on your own.
|
||||
|
||||
13. How can I make a Unix shared library?
|
||||
|
||||
make clean
|
||||
./configure -s
|
||||
make
|
||||
|
||||
14. How do I install a shared zlib library on Unix?
|
||||
|
||||
After the above, then:
|
||||
|
||||
make install
|
||||
|
||||
However, many flavors of Unix come with a shared zlib already installed.
|
||||
Before going to the trouble of compiling a shared version of zlib and
|
||||
trying to install it, you may want to check if it's already there! If you
|
||||
can #include <zlib.h>, it's there. The -lz option will probably link to it.
|
||||
|
||||
15. I have a question about OttoPDF.
|
||||
|
||||
We are not the authors of OttoPDF. The real author is on the OttoPDF web
|
||||
site: Joel Hainley, jhainley@myndkryme.com.
|
||||
|
||||
16. Can zlib decode Flate data in an Adobe PDF file?
|
||||
|
||||
Yes. See http://www.fastio.com/ (ClibPDF), or http://www.pdflib.com/ .
|
||||
To modify PDF forms, see http://sourceforge.net/projects/acroformtool/ .
|
||||
|
||||
17. Why am I getting this "register_frame_info not found" error on Solaris?
|
||||
|
||||
After installing zlib 1.1.4 on Solaris 2.6, running applications using zlib
|
||||
generates an error such as:
|
||||
|
||||
ld.so.1: rpm: fatal: relocation error: file /usr/local/lib/libz.so:
|
||||
symbol __register_frame_info: referenced symbol not found
|
||||
|
||||
The symbol __register_frame_info is not part of zlib, it is generated by
|
||||
the C compiler (cc or gcc). You must recompile applications using zlib
|
||||
which have this problem. This problem is specific to Solaris. See
|
||||
http://www.sunfreeware.com for Solaris versions of zlib and applications
|
||||
using zlib.
|
||||
|
||||
18. Why does gzip give an error on a file I make with compress/deflate?
|
||||
|
||||
The compress and deflate functions produce data in the zlib format, which
|
||||
is different and incompatible with the gzip format. The gz* functions in
|
||||
zlib on the other hand use the gzip format. Both the zlib and gzip
|
||||
formats use the same compressed data format internally, but have different
|
||||
headers and trailers around the compressed data.
|
||||
|
||||
19. Ok, so why are there two different formats?
|
||||
|
||||
The gzip format was designed to retain the directory information about
|
||||
a single file, such as the name and last modification date. The zlib
|
||||
format on the other hand was designed for in-memory and communication
|
||||
channel applications, and has a much more compact header and trailer and
|
||||
uses a faster integrity check than gzip.
|
||||
|
||||
20. Well that's nice, but how do I make a gzip file in memory?
|
||||
|
||||
You can request that deflate write the gzip format instead of the zlib
|
||||
format using deflateInit2(). You can also request that inflate decode
|
||||
the gzip format using inflateInit2(). Read zlib.h for more details.
|
||||
|
||||
21. Is zlib thread-safe?
|
||||
|
||||
Yes. However any library routines that zlib uses and any application-
|
||||
provided memory allocation routines must also be thread-safe. zlib's gz*
|
||||
functions use stdio library routines, and most of zlib's functions use the
|
||||
library memory allocation routines by default. zlib's Init functions allow
|
||||
for the application to provide custom memory allocation routines.
|
||||
|
||||
Of course, you should only operate on any given zlib or gzip stream from a
|
||||
single thread at a time.
|
||||
|
||||
22. Can I use zlib in my commercial application?
|
||||
|
||||
Yes. Please read the license in zlib.h.
|
||||
|
||||
23. Is zlib under the GNU license?
|
||||
|
||||
No. Please read the license in zlib.h.
|
||||
|
||||
24. The license says that altered source versions must be "plainly marked". So
|
||||
what exactly do I need to do to meet that requirement?
|
||||
|
||||
You need to change the ZLIB_VERSION and ZLIB_VERNUM #defines in zlib.h. In
|
||||
particular, the final version number needs to be changed to "f", and an
|
||||
identification string should be appended to ZLIB_VERSION. Version numbers
|
||||
x.x.x.f are reserved for modifications to zlib by others than the zlib
|
||||
maintainers. For example, if the version of the base zlib you are altering
|
||||
is "1.2.3.4", then in zlib.h you should change ZLIB_VERNUM to 0x123f, and
|
||||
ZLIB_VERSION to something like "1.2.3.f-zachary-mods-v3". You can also
|
||||
update the version strings in deflate.c and inftrees.c.
|
||||
|
||||
For altered source distributions, you should also note the origin and
|
||||
nature of the changes in zlib.h, as well as in ChangeLog and README, along
|
||||
with the dates of the alterations. The origin should include at least your
|
||||
name (or your company's name), and an email address to contact for help or
|
||||
issues with the library.
|
||||
|
||||
Note that distributing a compiled zlib library along with zlib.h and
|
||||
zconf.h is also a source distribution, and so you should change
|
||||
ZLIB_VERSION and ZLIB_VERNUM and note the origin and nature of the changes
|
||||
in zlib.h as you would for a full source distribution.
|
||||
|
||||
25. Will zlib work on a big-endian or little-endian architecture, and can I
|
||||
exchange compressed data between them?
|
||||
|
||||
Yes and yes.
|
||||
|
||||
26. Will zlib work on a 64-bit machine?
|
||||
|
||||
It should. It has been tested on 64-bit machines, and has no dependence
|
||||
on any data types being limited to 32-bits in length. If you have any
|
||||
difficulties, please provide a complete problem report to zlib@gzip.org
|
||||
|
||||
27. Will zlib decompress data from the PKWare Data Compression Library?
|
||||
|
||||
No. The PKWare DCL uses a completely different compressed data format
|
||||
than does PKZIP and zlib. However, you can look in zlib's contrib/blast
|
||||
directory for a possible solution to your problem.
|
||||
|
||||
28. Can I access data randomly in a compressed stream?
|
||||
|
||||
No, not without some preparation. If when compressing you periodically
|
||||
use Z_FULL_FLUSH, carefully write all the pending data at those points,
|
||||
and keep an index of those locations, then you can start decompression
|
||||
at those points. You have to be careful to not use Z_FULL_FLUSH too
|
||||
often, since it can significantly degrade compression.
|
||||
|
||||
29. Does zlib work on MVS, OS/390, CICS, etc.?
|
||||
|
||||
We don't know for sure. We have heard occasional reports of success on
|
||||
these systems. If you do use it on one of these, please provide us with
|
||||
a report, instructions, and patches that we can reference when we get
|
||||
these questions. Thanks.
|
||||
|
||||
30. Is there some simpler, easier to read version of inflate I can look at
|
||||
to understand the deflate format?
|
||||
|
||||
First off, you should read RFC 1951. Second, yes. Look in zlib's
|
||||
contrib/puff directory.
|
||||
|
||||
31. Does zlib infringe on any patents?
|
||||
|
||||
As far as we know, no. In fact, that was originally the whole point behind
|
||||
zlib. Look here for some more information:
|
||||
|
||||
http://www.gzip.org/#faq11
|
||||
|
||||
32. Can zlib work with greater than 4 GB of data?
|
||||
|
||||
Yes. inflate() and deflate() will process any amount of data correctly.
|
||||
Each call of inflate() or deflate() is limited to input and output chunks
|
||||
of the maximum value that can be stored in the compiler's "unsigned int"
|
||||
type, but there is no limit to the number of chunks. Note however that the
|
||||
strm.total_in and strm_total_out counters may be limited to 4 GB. These
|
||||
counters are provided as a convenience and are not used internally by
|
||||
inflate() or deflate(). The application can easily set up its own counters
|
||||
updated after each call of inflate() or deflate() to count beyond 4 GB.
|
||||
compress() and uncompress() may be limited to 4 GB, since they operate in a
|
||||
single call. gzseek() and gztell() may be limited to 4 GB depending on how
|
||||
zlib is compiled. See the zlibCompileFlags() function in zlib.h.
|
||||
|
||||
The word "may" appears several times above since there is a 4 GB limit
|
||||
only if the compiler's "long" type is 32 bits. If the compiler's "long"
|
||||
type is 64 bits, then the limit is 16 exabytes.
|
||||
|
||||
33. Does zlib have any security vulnerabilities?
|
||||
|
||||
The only one that we are aware of is potentially in gzprintf(). If zlib
|
||||
is compiled to use sprintf() or vsprintf(), then there is no protection
|
||||
against a buffer overflow of a 4K string space, other than the caller of
|
||||
gzprintf() assuring that the output will not exceed 4K. On the other
|
||||
hand, if zlib is compiled to use snprintf() or vsnprintf(), which should
|
||||
normally be the case, then there is no vulnerability. The ./configure
|
||||
script will display warnings if an insecure variation of sprintf() will
|
||||
be used by gzprintf(). Also the zlibCompileFlags() function will return
|
||||
information on what variant of sprintf() is used by gzprintf().
|
||||
|
||||
If you don't have snprintf() or vsnprintf() and would like one, you can
|
||||
find a portable implementation here:
|
||||
|
||||
http://www.ijs.si/software/snprintf/
|
||||
|
||||
Note that you should be using the most recent version of zlib. Versions
|
||||
1.1.3 and before were subject to a double-free vulnerability.
|
||||
|
||||
34. Is there a Java version of zlib?
|
||||
|
||||
Probably what you want is to use zlib in Java. zlib is already included
|
||||
as part of the Java SDK in the java.util.zip package. If you really want
|
||||
a version of zlib written in the Java language, look on the zlib home
|
||||
page for links: http://www.zlib.org/
|
||||
|
||||
35. I get this or that compiler or source-code scanner warning when I crank it
|
||||
up to maximally-pedantic. Can't you guys write proper code?
|
||||
|
||||
Many years ago, we gave up attempting to avoid warnings on every compiler
|
||||
in the universe. It just got to be a waste of time, and some compilers
|
||||
were downright silly. So now, we simply make sure that the code always
|
||||
works.
|
||||
|
||||
36. Valgrind (or some similar memory access checker) says that deflate is
|
||||
performing a conditional jump that depends on an uninitialized value.
|
||||
Isn't that a bug?
|
||||
|
||||
No. That is intentional for performance reasons, and the output of
|
||||
deflate is not affected. This only started showing up recently since
|
||||
zlib 1.2.x uses malloc() by default for allocations, whereas earlier
|
||||
versions used calloc(), which zeros out the allocated memory.
|
||||
|
||||
37. Will zlib read the (insert any ancient or arcane format here) compressed
|
||||
data format?
|
||||
|
||||
Probably not. Look in the comp.compression FAQ for pointers to various
|
||||
formats and associated software.
|
||||
|
||||
38. How can I encrypt/decrypt zip files with zlib?
|
||||
|
||||
zlib doesn't support encryption. The original PKZIP encryption is very weak
|
||||
and can be broken with freely available programs. To get strong encryption,
|
||||
use GnuPG, http://www.gnupg.org/ , which already includes zlib compression.
|
||||
For PKZIP compatible "encryption", look at http://www.info-zip.org/
|
||||
|
||||
39. What's the difference between the "gzip" and "deflate" HTTP 1.1 encodings?
|
||||
|
||||
"gzip" is the gzip format, and "deflate" is the zlib format. They should
|
||||
probably have called the second one "zlib" instead to avoid confusion
|
||||
with the raw deflate compressed data format. While the HTTP 1.1 RFC 2616
|
||||
correctly points to the zlib specification in RFC 1950 for the "deflate"
|
||||
transfer encoding, there have been reports of servers and browsers that
|
||||
incorrectly produce or expect raw deflate data per the deflate
|
||||
specficiation in RFC 1951, most notably Microsoft. So even though the
|
||||
"deflate" transfer encoding using the zlib format would be the more
|
||||
efficient approach (and in fact exactly what the zlib format was designed
|
||||
for), using the "gzip" transfer encoding is probably more reliable due to
|
||||
an unfortunate choice of name on the part of the HTTP 1.1 authors.
|
||||
|
||||
Bottom line: use the gzip format for HTTP 1.1 encoding.
|
||||
|
||||
40. Does zlib support the new "Deflate64" format introduced by PKWare?
|
||||
|
||||
No. PKWare has apparently decided to keep that format proprietary, since
|
||||
they have not documented it as they have previous compression formats.
|
||||
In any case, the compression improvements are so modest compared to other
|
||||
more modern approaches, that it's not worth the effort to implement.
|
||||
|
||||
41. Can you please sign these lengthy legal documents and fax them back to us
|
||||
so that we can use your software in our product?
|
||||
|
||||
No. Go away. Shoo.

ZLIB DATA COMPRESSION LIBRARY
|
||||
|
||||
zlib 1.2.3 is a general purpose data compression library. All the code is
|
||||
thread safe. The data format used by the zlib library is described by RFCs
|
||||
(Request for Comments) 1950 to 1952 in the files
|
||||
http://www.ietf.org/rfc/rfc1950.txt (zlib format), rfc1951.txt (deflate format)
|
||||
and rfc1952.txt (gzip format). These documents are also available in other
|
||||
formats from ftp://ftp.uu.net/graphics/png/documents/zlib/zdoc-index.html
|
||||
|
||||
All functions of the compression library are documented in the file zlib.h
|
||||
(volunteer to write man pages welcome, contact zlib@gzip.org). A usage example
|
||||
of the library is given in the file example.c which also tests that the library
|
||||
is working correctly. Another example is given in the file minigzip.c. The
|
||||
compression library itself is composed of all source files except example.c and
|
||||
minigzip.c.
|
||||
|
||||
To compile all files and run the test program, follow the instructions given at
|
||||
the top of Makefile. In short "make test; make install" should work for most
|
||||
machines. For Unix: "./configure; make test; make install". For MSDOS, use one
|
||||
of the special makefiles such as Makefile.msc. For VMS, use make_vms.com.
|
||||
|
||||
Questions about zlib should be sent to <zlib@gzip.org>, or to Gilles Vollant
|
||||
<info@winimage.com> for the Windows DLL version. The zlib home page is
|
||||
http://www.zlib.org or http://www.gzip.org/zlib/ Before reporting a problem,
|
||||
please check this site to verify that you have the latest version of zlib;
|
||||
otherwise get the latest version and check whether the problem still exists or
|
||||
not.
|
||||
|
||||
PLEASE read the zlib FAQ http://www.gzip.org/zlib/zlib_faq.html before asking
|
||||
for help.
|
||||
|
||||
Mark Nelson <markn@ieee.org> wrote an article about zlib for the Jan. 1997
|
||||
issue of Dr. Dobb's Journal; a copy of the article is available in
|
||||
http://dogma.net/markn/articles/zlibtool/zlibtool.htm
|
||||
|
||||
The changes made in version 1.2.3 are documented in the file ChangeLog.
|
||||
|
||||
Unsupported third party contributions are provided in directory "contrib".
|
||||
|
||||
A Java implementation of zlib is available in the Java Development Kit
|
||||
http://java.sun.com/j2se/1.4.2/docs/api/java/util/zip/package-summary.html
|
||||
See the zlib home page http://www.zlib.org for details.
|
||||
|
||||
A Perl interface to zlib written by Paul Marquess <pmqs@cpan.org> is in the
|
||||
CPAN (Comprehensive Perl Archive Network) sites
|
||||
http://www.cpan.org/modules/by-module/Compress/
|
||||
|
||||
A Python interface to zlib written by A.M. Kuchling <amk@amk.ca> is
|
||||
available in Python 1.5 and later versions, see
|
||||
http://www.python.org/doc/lib/module-zlib.html
|
||||
|
||||
A zlib binding for TCL written by Andreas Kupries <a.kupries@westend.com> is
|
||||
availlable at http://www.oche.de/~akupries/soft/trf/trf_zip.html
|
||||
|
||||
An experimental package to read and write files in .zip format, written on top
|
||||
of zlib by Gilles Vollant <info@winimage.com>, is available in the
|
||||
contrib/minizip directory of zlib.
|
||||
|
||||
|
||||
Notes for some targets:
|
||||
|
||||
- For Windows DLL versions, please see win32/DLL_FAQ.txt
|
||||
|
||||
- For 64-bit Irix, deflate.c must be compiled without any optimization. With
|
||||
-O, one libpng test fails. The test works in 32 bit mode (with the -n32
|
||||
compiler flag). The compiler bug has been reported to SGI.
|
||||
|
||||
- zlib doesn't work with gcc 2.6.3 on a DEC 3000/300LX under OSF/1 2.1 it works
|
||||
when compiled with cc.
|
||||
|
||||
- On Digital Unix 4.0D (formely OSF/1) on AlphaServer, the cc option -std1 is
|
||||
necessary to get gzprintf working correctly. This is done by configure.
|
||||
|
||||
- zlib doesn't work on HP-UX 9.05 with some versions of /bin/cc. It works with
|
||||
other compilers. Use "make test" to check your compiler.
|
||||
|
||||
- gzdopen is not supported on RISCOS, BEOS and by some Mac compilers.
|
||||
|
||||
- For PalmOs, see http://palmzlib.sourceforge.net/
|
||||
|
||||
- When building a shared, i.e. dynamic library on Mac OS X, the library must be
|
||||
installed before testing (do "make install" before "make test"), since the
|
||||
library location is specified in the library.
|
||||
|
||||
|
||||
Acknowledgments:
|
||||
|
||||
The deflate format used by zlib was defined by Phil Katz. The deflate
|
||||
and zlib specifications were written by L. Peter Deutsch. Thanks to all the
|
||||
people who reported problems and suggested various improvements in zlib;
|
||||
they are too numerous to cite here.

1. Compression algorithm (deflate)
|
||||
|
||||
The deflation algorithm used by gzip (also zip and zlib) is a variation of
|
||||
LZ77 (Lempel-Ziv 1977, see reference below). It finds duplicated strings in
|
||||
the input data. The second occurrence of a string is replaced by a
|
||||
pointer to the previous string, in the form of a pair (distance,
|
||||
length). Distances are limited to 32K bytes, and lengths are limited
|
||||
to 258 bytes. When a string does not occur anywhere in the previous
|
||||
32K bytes, it is emitted as a sequence of literal bytes. (In this
|
||||
description, `string' must be taken as an arbitrary sequence of bytes,
|
||||
and is not restricted to printable characters.)
|
||||
|
||||
Literals or match lengths are compressed with one Huffman tree, and
|
||||
match distances are compressed with another tree. The trees are stored
|
||||
in a compact form at the start of each block. The blocks can have any
|
||||
size (except that the compressed data for one block must fit in
|
||||
available memory). A block is terminated when deflate() determines that
|
||||
it would be useful to start another block with fresh trees. (This is
|
||||
somewhat similar to the behavior of LZW-based _compress_.)
|
||||
|
||||
Duplicated strings are found using a hash table. All input strings of
|
||||
length 3 are inserted in the hash table. A hash index is computed for
|
||||
the next 3 bytes. If the hash chain for this index is not empty, all
|
||||
strings in the chain are compared with the current input string, and
|
||||
the longest match is selected.
|
||||
|
||||
The hash chains are searched starting with the most recent strings, to
|
||||
favor small distances and thus take advantage of the Huffman encoding.
|
||||
The hash chains are singly linked. There are no deletions from the
|
||||
hash chains, the algorithm simply discards matches that are too old.
|
||||
|
||||
To avoid a worst-case situation, very long hash chains are arbitrarily
|
||||
truncated at a certain length, determined by a runtime option (level
|
||||
parameter of deflateInit). So deflate() does not always find the longest
|
||||
possible match but generally finds a match which is long enough.
|
||||
|
||||
deflate() also defers the selection of matches with a lazy evaluation
|
||||
mechanism. After a match of length N has been found, deflate() searches for
|
||||
a longer match at the next input byte. If a longer match is found, the
|
||||
previous match is truncated to a length of one (thus producing a single
|
||||
literal byte) and the process of lazy evaluation begins again. Otherwise,
|
||||
the original match is kept, and the next match search is attempted only N
|
||||
steps later.
|
||||
|
||||
The lazy match evaluation is also subject to a runtime parameter. If
|
||||
the current match is long enough, deflate() reduces the search for a longer
|
||||
match, thus speeding up the whole process. If compression ratio is more
|
||||
important than speed, deflate() attempts a complete second search even if
|
||||
the first match is already long enough.
|
||||
|
||||
The lazy match evaluation is not performed for the fastest compression
|
||||
modes (level parameter 1 to 3). For these fast modes, new strings
|
||||
are inserted in the hash table only when no match was found, or
|
||||
when the match is not too long. This degrades the compression ratio
|
||||
but saves time since there are both fewer insertions and fewer searches.
|
||||
|
||||
|
||||
2. Decompression algorithm (inflate)
|
||||
|
||||
2.1 Introduction
|
||||
|
||||
The key question is how to represent a Huffman code (or any prefix code) so
|
||||
that you can decode fast. The most important characteristic is that shorter
|
||||
codes are much more common than longer codes, so pay attention to decoding the
|
||||
short codes fast, and let the long codes take longer to decode.
|
||||
|
||||
inflate() sets up a first level table that covers some number of bits of
|
||||
input less than the length of longest code. It gets that many bits from the
|
||||
stream, and looks it up in the table. The table will tell if the next
|
||||
code is that many bits or less and how many, and if it is, it will tell
|
||||
the value, else it will point to the next level table for which inflate()
|
||||
grabs more bits and tries to decode a longer code.
|
||||
|
||||
How many bits to make the first lookup is a tradeoff between the time it
|
||||
takes to decode and the time it takes to build the table. If building the
|
||||
table took no time (and if you had infinite memory), then there would only
|
||||
be a first level table to cover all the way to the longest code. However,
|
||||
building the table ends up taking a lot longer for more bits since short
|
||||
codes are replicated many times in such a table. What inflate() does is
|
||||
simply to make the number of bits in the first table a variable, and then
|
||||
to set that variable for the maximum speed.
|
||||
|
||||
For inflate, which has 286 possible codes for the literal/length tree, the size
|
||||
of the first table is nine bits. Also the distance trees have 30 possible
|
||||
values, and the size of the first table is six bits. Note that for each of
|
||||
those cases, the table ended up one bit longer than the ``average'' code
|
||||
length, i.e. the code length of an approximately flat code which would be a
|
||||
little more than eight bits for 286 symbols and a little less than five bits
|
||||
for 30 symbols.
|
||||
|
||||
|
||||
2.2 More details on the inflate table lookup
|
||||
|
||||
Ok, you want to know what this cleverly obfuscated inflate tree actually
|
||||
looks like. You are correct that it's not a Huffman tree. It is simply a
|
||||
lookup table for the first, let's say, nine bits of a Huffman symbol. The
|
||||
symbol could be as short as one bit or as long as 15 bits. If a particular
|
||||
symbol is shorter than nine bits, then that symbol's translation is duplicated
|
||||
in all those entries that start with that symbol's bits. For example, if the
|
||||
symbol is four bits, then it's duplicated 32 times in a nine-bit table. If a
|
||||
symbol is nine bits long, it appears in the table once.
|
||||
|
||||
If the symbol is longer than nine bits, then that entry in the table points
|
||||
to another similar table for the remaining bits. Again, there are duplicated
|
||||
entries as needed. The idea is that most of the time the symbol will be short
|
||||
and there will only be one table look up. (That's whole idea behind data
|
||||
compression in the first place.) For the less frequent long symbols, there
|
||||
will be two lookups. If you had a compression method with really long
|
||||
symbols, you could have as many levels of lookups as is efficient. For
|
||||
inflate, two is enough.
|
||||
|
||||
So a table entry either points to another table (in which case nine bits in
|
||||
the above example are gobbled), or it contains the translation for the symbol
|
||||
and the number of bits to gobble. Then you start again with the next
|
||||
ungobbled bit.
|
||||
|
||||
You may wonder: why not just have one lookup table for how ever many bits the
|
||||
longest symbol is? The reason is that if you do that, you end up spending
|
||||
more time filling in duplicate symbol entries than you do actually decoding.
|
||||
At least for deflate's output that generates new trees every several 10's of
|
||||
kbytes. You can imagine that filling in a 2^15 entry table for a 15-bit code
|
||||
would take too long if you're only decoding several thousand symbols. At the
|
||||
other extreme, you could make a new table for every bit in the code. In fact,
|
||||
that's essentially a Huffman tree. But then you spend two much time
|
||||
traversing the tree while decoding, even for short symbols.
|
||||
|
||||
So the number of bits for the first lookup table is a trade of the time to
|
||||
fill out the table vs. the time spent looking at the second level and above of
|
||||
the table.
|
||||
|
||||
Here is an example, scaled down:
|
||||
|
||||
The code being decoded, with 10 symbols, from 1 to 6 bits long:
|
||||
|
||||
A: 0
|
||||
B: 10
|
||||
C: 1100
|
||||
D: 11010
|
||||
E: 11011
|
||||
F: 11100
|
||||
G: 11101
|
||||
H: 11110
|
||||
I: 111110
|
||||
J: 111111
|
||||
|
||||
Let's make the first table three bits long (eight entries):
|
||||
|
||||
000: A,1
|
||||
001: A,1
|
||||
010: A,1
|
||||
011: A,1
|
||||
100: B,2
|
||||
101: B,2
|
||||
110: -> table X (gobble 3 bits)
|
||||
111: -> table Y (gobble 3 bits)
|
||||
|
||||
Each entry is what the bits decode as and how many bits that is, i.e. how
|
||||
many bits to gobble. Or the entry points to another table, with the number of
|
||||
bits to gobble implicit in the size of the table.
|
||||
|
||||
Table X is two bits long since the longest code starting with 110 is five bits
|
||||
long:
|
||||
|
||||
00: C,1
|
||||
01: C,1
|
||||
10: D,2
|
||||
11: E,2
|
||||
|
||||
Table Y is three bits long since the longest code starting with 111 is six
|
||||
bits long:
|
||||
|
||||
000: F,2
|
||||
001: F,2
|
||||
010: G,2
|
||||
011: G,2
|
||||
100: H,2
|
||||
101: H,2
|
||||
110: I,3
|
||||
111: J,3
|
||||
|
||||
So what we have here are three tables with a total of 20 entries that had to
|
||||
be constructed. That's compared to 64 entries for a single table. Or
|
||||
compared to 16 entries for a Huffman tree (six two entry tables and one four
|
||||
entry table). Assuming that the code ideally represents the probability of
|
||||
the symbols, it takes on the average 1.25 lookups per symbol. That's compared
|
||||
to one lookup for the single table, or 1.66 lookups per symbol for the
|
||||
Huffman tree.
|
||||
|
||||
There, I think that gives you a picture of what's going on. For inflate, the
|
||||
meaning of a particular symbol is often more than just a letter. It can be a
|
||||
byte (a "literal"), or it can be either a length or a distance which
|
||||
indicates a base value and a number of bits to fetch after the code that is
|
||||
added to the base value. Or it might be the special end-of-block code. The
|
||||
data structures created in inftrees.c try to encode all that information
|
||||
compactly in the tables.

/*
|
||||
Notes beyond the 1.93a appnote.txt:
|
||||
|
||||
1. Distance pointers never point before the beginning of the output
|
||||
stream.
|
||||
2. Distance pointers can point back across blocks, up to 32k away.
|
||||
3. There is an implied maximum of 7 bits for the bit length table and
|
||||
15 bits for the actual data.
|
||||
4. If only one code exists, then it is encoded using one bit. (Zero
|
||||
would be more efficient, but perhaps a little confusing.) If two
|
||||
codes exist, they are coded using one bit each (0 and 1).
|
||||
5. There is no way of sending zero distance codes--a dummy must be
|
||||
sent if there are none. (History: a pre 2.0 version of PKZIP would
|
||||
store blocks with no distance codes, but this was discovered to be
|
||||
too harsh a criterion.) Valid only for 1.93a. 2.04c does allow
|
||||
zero distance codes, which is sent as one code of zero bits in
|
||||
length.
|
||||
6. There are up to 286 literal/length codes. Code 256 represents the
|
||||
end-of-block. Note however that the static length tree defines
|
||||
288 codes just to fill out the Huffman codes. Codes 286 and 287
|
||||
cannot be used though, since there is no length base or extra bits
|
||||
defined for them. Similarily, there are up to 30 distance codes.
|
||||
However, static trees define 32 codes (all 5 bits) to fill out the
|
||||
Huffman codes, but the last two had better not show up in the data.
|
||||
7. Unzip can check dynamic Huffman blocks for complete code sets.
|
||||
The exception is that a single code would not be complete (see #4).
|
||||
8. The five bits following the block type is really the number of
|
||||
literal codes sent minus 257.
|
||||
9. Length codes 8,16,16 are interpreted as 13 length codes of 8 bits
|
||||
(1+6+6). Therefore, to output three times the length, you output
|
||||
three codes (1+1+1), whereas to output four times the same length,
|
||||
you only need two codes (1+3). Hmm.
|
||||
10. In the tree reconstruction algorithm, Code = Code + Increment
|
||||
only if BitLength(i) is not zero. (Pretty obvious.)
|
||||
11. Correction: 4 Bits: # of Bit Length codes - 4 (4 - 19)
|
||||
12. Note: length code 284 can represent 227-258, but length code 285
|
||||
really is 258. The last length deserves its own, short code
|
||||
since it gets used a lot in very redundant files. The length
|
||||
258 is special since 258 - 3 (the min match length) is 255.
|
||||
13. The literal/length and distance code bit lengths are read as a
|
||||
single stream of lengths. It is possible (and advantageous) for
|
||||
a repeat code (16, 17, or 18) to go across the boundary between
|
||||
the two sets of lengths.

available, an end-of-block is encountered, or a data error is encountered.
|
||||
When large enough input and output buffers are supplied to inflate(), for
|
||||
example, a 16K input buffer and a 64K output buffer, more than 95% of the
|
||||
inflate execution time is spent in this routine.
|
||||
|
||||
Entry assumptions:
|
||||
|
||||
state->mode == LEN
|
||||
strm->avail_in >= 6
|
||||
strm->avail_out >= 258
|
||||
start >= strm->avail_out
|
||||
state->bits < 8
|
||||
|
||||
On return, state->mode is one of:
|
||||
|
||||
LEN -- ran out of enough output space or enough available input
|
||||
TYPE -- reached end of block code, inflate() to interpret next block
|
||||
BAD -- error in block data
|
||||
|
||||
Notes:
|
||||
|
||||
- The maximum input bits used by a length/distance pair is 15 bits for the
|
||||
length code, 5 bits for the length extra, 15 bits for the distance code,
|
||||
and 13 bits for the distance extra. This totals 48 bits, or six bytes.
|
||||
Therefore if strm->avail_in >= 6, then there is enough input to avoid
|
||||
checking for available input while decoding.
|
||||
|
||||
- The maximum bytes that a single length/distance pair can output is 258
|
||||
bytes, which is the maximum length that can be coded. inflate_fast()
|
||||
requires strm->avail_out >= 258 for each loop to avoid checking for
|
||||
output space.

|

Process a set of code lengths to create a canonical Huffman code. The
|
||||
code lengths are lens[0..codes-1]. Each length corresponds to the
|
||||
symbols 0..codes-1. The Huffman code is generated by first sorting the
|
||||
symbols by length from short to long, and retaining the symbol order
|
||||
for codes with equal lengths. Then the code starts with all zero bits
|
||||
for the first code of the shortest length, and the codes are integer
|
||||
increments for the same length, and zeros are appended as the length
|
||||
increases. For the deflate format, these bits are stored backwards
|
||||
from their more natural integer increment ordering, and so when the
|
||||
decoding tables are built in the large loop below, the integer codes
|
||||
are incremented backwards.
|
||||
|
||||
This routine assumes, but does not check, that all of the entries in
|
||||
lens[] are in the range 0..MAXBITS. The caller must assure this.
|
||||
1..MAXBITS is interpreted as that code length. zero means that that
|
||||
symbol does not occur in this code.
|
||||
|
||||
The codes are sorted by computing a count of codes for each length,
|
||||
creating from that a table of starting indices for each length in the
|
||||
sorted table, and then entering the symbols in order in the sorted
|
||||
table. The sorted table is work[], with that space being provided by
|
||||
the caller.
|
||||
|
||||
The length counts are used for other purposes as well, i.e. finding
|
||||
the minimum and maximum length codes, determining if there are any
|
||||
codes at all, checking for a valid set of lengths, and looking ahead
|
||||
at length counts to determine sub-table sizes when building the

decoding tables.

Create and fill in decoding tables. In this loop, the table being

with length len. That code is converted to an index by dropping drop

bits off of the bottom. For codes where len is less than drop + curr,

those top drop + curr - len bits are incremented through all values to

root is the number of index bits for the root table. When len exceeds

new sub-table should be started. drop is zero when the root table is

being filled, and drop is root when sub-tables are being filled.
|
||||
|
||||
When a new sub-table is needed, it is necessary to look ahead in the
|

code lengths to determine what size sub-table is needed. The length
|
||||
counts are used for this, and so count[] is decremented as codes are

entered in the tables.

used keeps track of how many table entries have been allocated from the

provided *table space. It is checked when a LENS table is being made
|
||||
against the space in *table, ENOUGH, minus the maximum space needed by
|
||||
the worst case distance code, MAXD. This should never happen, but the
|
||||
sufficiency of ENOUGH has not been proven exhaustively, hence the check.
|
||||

.TH ZLIB 3 "18 July 2005"
|
||||
.SH NAME
|
||||
zlib \- compression/decompression library
|
||||
.SH SYNOPSIS
|
||||
[see
|
||||
.I zlib.h
|
||||
for full description]
|
||||
.SH DESCRIPTION
|
||||
The
|
||||
.I zlib
|
||||
library is a general purpose data compression library.
|
||||
The code is thread safe.
|
||||
It provides in-memory compression and decompression functions,
|
||||
including integrity checks of the uncompressed data.
|
||||
This version of the library supports only one compression method (deflation)
|
||||
but other algorithms will be added later
|
||||
and will have the same stream interface.
|
||||
.LP
|
||||
Compression can be done in a single step if the buffers are large enough
|
||||
(for example if an input file is mmap'ed),
|
||||
or can be done by repeated calls of the compression function.
|
||||
In the latter case,
|
||||
the application must provide more input and/or consume the output
|
||||
(providing more output space) before each call.
|
||||
.LP
|
||||
The library also supports reading and writing files in
|
||||
.IR gzip (1)
|
||||
(.gz) format
|
||||
with an interface similar to that of stdio.
|
||||
.LP
|
||||
The library does not install any signal handler.
|
||||
The decoder checks the consistency of the compressed data,
|
||||
so the library should never crash even in case of corrupted input.
|
||||
.LP
|
||||
All functions of the compression library are documented in the file
|
||||
.IR zlib.h .
|
||||
The distribution source includes examples of use of the library
|
||||
in the files
|
||||
.I example.c
|
||||
and
|
||||
.IR minigzip.c .
|
||||
.LP
|
||||
Changes to this version are documented in the file
|
||||
.I ChangeLog
|
||||
that accompanies the source,
|
||||
and are concerned primarily with bug fixes and portability enhancements.
|
||||
