Frequently Asked Questions about zlib
If your question is not there, please check the zlib home page
http://www.cdrom.com/pub/infozip/zlib/ which may have more recent information.
1) I need a Windows DLL
2) I need a Visual Basic interface to zlib
3) compress() returns Z_BUF_ERROR
4) deflate or inflate returns Z_BUF_ERROR
5) Where is the zlib documentation (man pages, etc...)?
6) Why don't you use GNU autoconf, libtool, etc...?
7) There is a bug in zlib.
8) I get "undefined reference to gzputc"
1) I need a Windows DLL
The zlib sources can be compiled without change to produce a DLL.
If you want a precompiled DLL, see http://www.winimage.com/zLibDll
2) I need a Visual Basic interface to zlib
See http://www.tcfb.com/dowseware/cmp-z-it.zip
http://web2.airmail.net/markn/articles/zlibtool/zlibtool.htm
and contrib/visual-basic.txt
3) 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").
4) deflate or inflate returns Z_BUF_ERROR
Make sure that before the call avail_in and avail_out are not zero.
5) Where is the zlib documentation (man pages, etc...)?
It's in zlib.h for the moment. Volunteers to transform this
to man pages, please contact jloup@gzip.org. Examples of zlib usage
are in the files example.c and minigzip.c.
6) Why don't you use GNU autoconf, libtool, etc...?
Because we would like to keep zlib as a very small and simple package.
zlib is rather portable and doesn't need much configuration.
7) There is 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 us the corresponding source at zlib@quest.jpl.nasa.gov
Do not send multi-megabyte data files without prior agreement.
8) I get "undefined reference to gzputc"
If "make test" produces something like
example.o(.text+0x174):
check that you don't have old files libz.* in /usr/lib, /usr/local/lib
or /usr/X11R6/lib. Remove old versions then do "make install".

zlib/README 0 → 100644
zlib 1.1.3 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
ftp://ds.internic.net/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 jloup@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 or descrip.mms.
Questions about zlib should be sent to <zlib@quest.jpl.nasa.gov>, or to
Gilles Vollant <info@winimage.com> for the Windows DLL version.
The zlib home page is http://www.cdrom.com/pub/infozip/zlib/
The official zlib ftp site is ftp://ftp.cdrom.com/pub/infozip/zlib/
Before reporting a problem, please check those sites to verify that
you have the latest version of zlib; otherwise get the latest version and
check whether the problem still exists or not.
Mark Nelson <markn@tiny.com> wrote an article about zlib for the Jan. 1997
issue of Dr. Dobb's Journal; a copy of the article is available in
http://web2.airmail.net/markn/articles/zlibtool/zlibtool.htm
The changes made in version 1.1.3 are documented in the file ChangeLog.
The main changes since 1.1.2 are:
- fix "an inflate input buffer bug that shows up on rare but persistent
occasions" (Mark)
- fix gzread and gztell for concatenated .gz files (Didier Le Botlan)
- fix gzseek(..., SEEK_SET) in write mode
- fix crc check after a gzeek (Frank Faubert)
- fix miniunzip when the last entry in a zip file is itself a zip file
(J Lillge)
- add contrib/asm586 and contrib/asm686 (Brian Raiter)
See http://www.muppetlabs.com/~breadbox/software/assembly.html
- add support for Delphi 3 in contrib/delphi (Bob Dellaca)
- add support for C++Builder 3 and Delphi 3 in contrib/delphi2 (Davide Moretti)
- do not exit prematurely in untgz if 0 at start of block (Magnus Holmgren)
- use macro EXTERN instead of extern to support DLL for BeOS (Sander Stoks)
- added a FAQ file
plus many changes for portability.
Unsupported third party contributions are provided in directory "contrib".
A Java implementation of zlib is available in the Java Development Kit 1.1
http://www.javasoft.com/products/JDK/1.1/docs/api/Package-java.util.zip.html
See the zlib home page http://www.cdrom.com/pub/infozip/zlib/ for details.
A Perl interface to zlib written by Paul Marquess <pmarquess@bfsec.bt.co.uk>
is in the CPAN (Comprehensive Perl Archive Network) sites, such as:
ftp://ftp.cis.ufl.edu/pub/perl/CPAN/modules/by-module/Compress/Compress-Zlib*
A Python interface to zlib written by A.M. Kuchling <amk@magnet.com>
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.westend.com/~kupries/doc/trf/man/man.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 at http://www.winimage.com/zLibDll/unzip.html
and also in the contrib/minizip directory of zlib.
Notes for some targets:
- To build a Windows DLL version, include in a DLL project zlib.def, zlib.rc
and all .c files except example.c and minigzip.c; compile with -DZLIB_DLL
The zlib DLL support was initially done by Alessandro Iacopetti and is
now maintained by Gilles Vollant <info@winimage.com>. Check the zlib DLL
home page at http://www.winimage.com/zLibDll
From Visual Basic, you can call the DLL functions which do not take
a structure as argument: compress, uncompress and all gz* functions.
See contrib/visual-basic.txt for more information, or get

- 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 Turbo C the small model is supported only with reduced performance to
avoid any far allocation; it was tested with -DMAX_WBITS=11 -DMAX_MEM_LEVEL=3
- For PalmOs, see http://www.cs.uit.no/~perm/PASTA/pilot/software.html

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 real question is, given a Huffman tree, how to decode fast. The most
important realization 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 set it
for the maximum speed.
inflate() sends new trees relatively often, so it is possibly set for a
smaller first level table than an application that has only one tree for
all the data. 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. It would be
interesting to see if optimizing the first level table for other
applications gave values within a bit or two of the flat code size.
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 to 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.

zlib/contrib/asm586/README.586 0 → 100644
This is a patched version of zlib modified to use
Pentium-optimized assembly code in the deflation algorithm. The files
changed/added by this patch are:
README.586
match.S
The effectiveness of these modifications is a bit marginal, as the the
program's bottleneck seems to be mostly L1-cache contention, for which
there is no real way to work around without rewriting the basic
algorithm. The speedup on average is around 5-10% (which is generally
less than the amount of variance between subsequent executions).
However, when used at level 9 compression, the cache contention can
drop enough for the assembly version to achieve 10-20% speedup (and
sometimes more, depending on the amount of overall redundancy in the
files). Even here, though, cache contention can still be the limiting
factor, depending on the nature of the program using the zlib library.
This may also mean that better improvements will be seen on a Pentium
with MMX, which suffers much less from L1-cache contention, but I have
not yet verified this.
Note that this code has been tailored for the Pentium in particular,
and will not perform well on the Pentium Pro (due to the use of a
partial register in the inner loop).
If you are using an assembler other than GNU as, you will have to
translate match.S to use your assembler's syntax. (Have fun.)

zlib/contrib/asm686/README.686 0 → 100644
This is a patched version of zlib, modified to use
Pentium-Pro-optimized assembly code in the deflation algorithm. The
files changed/added by this patch are:
README.686
match.S
The speedup that this patch provides varies, depending on whether the
compiler used to build the original version of zlib falls afoul of the
PPro's speed traps. My own tests show a speedup of around 10-20% at
the default compression level, and 20-30% using -9, against a version
compiled using gcc 2.7.2.3. Your mileage may vary.
Note that this code has been tailored for the PPro/PII in particular,
and will not perform particuarly well on a Pentium.
If you are using an assembler other than GNU as, you will have to
translate match.S to use your assembler's syntax. (Have fun.)

These are files used to compile zlib under Borland C++ Builder 3.
zlib.bpg is the main project group that can be loaded in the BCB IDE and
loads all other *.bpr projects
zlib.bpr is a project used to create a static zlib.lib library with C calling
convention for functions.
zlib32.bpr creates a zlib32.dll dynamic link library with Windows standard
calling convention.
d_zlib.bpr creates a set of .obj files with register calling convention.
These files are used by zlib.pas to create a Delphi unit containing zlib.
The d_zlib.lib file generated isn't useful and can be deleted.
zlib.cpp, zlib32.cpp and d_zlib.cpp are used by the above projects.

//
// If your DLL uses VCL and exports any functions that pass VCL String objects

// results, you will need to build both your DLL project and any EXE projects
// that use your DLL with the dynamic RTL (the RTL DLL). This will change your
// DLL and its calling EXE's to use BORLNDMM.DLL as their memory manager. In
// these cases, the file BORLNDMM.DLL should be deployed along with your DLL
// and the RTL DLL (CP3240MT.DLL). To avoid the requiring BORLNDMM.DLL in
// these situations, pass string information using "char *" or ShortString
// parameters and then link with the static RTL.

UnZip 0.15 additionnal library
This unzip package allow extract file from .ZIP file, compatible with
PKZip 2.04g, WinZip, InfoZip tools and compatible.
Multi volume ZipFile (span) are not supported, and old compression used by old
PKZip 1.x are not supported.
See probdesc.zip from PKWare for specification of .ZIP format.
What is Unzip
The Zlib library support the deflate compression and the creation of gzip (.gz)
file. Zlib is free and small.
The .Zip format, which can contain several compressed files (.gz can containt
only one file) is a very popular format. This is why I've written a package for reading file compressed in Zipfile.
Using Unzip package
You need source of Zlib (get zlib111.zip and read zlib.h).
Get unzlb015.zip and read unzip.h (whith documentation of unzip functions)
The Unzip package is only two file : unzip.h and unzip.c. But it use the Zlib
files.
unztst.c is a simple sample program, which list file in a zipfile and display
README.TXT or FILE_ID.DIZ (if these files are found).
miniunz.c is a mini unzip program.
I'm also currenlyt writing a zipping portion (zip.h, zip.c and test with minizip.c)
Please email me for feedback.
I hope my source is compatible with Unix system, but I need your help for be sure
