"""Core options text extractor
The purpose of this script is to set up & provide functions for automatic generation of 'libretro_core_options_intl.h'
from 'libretro_core_options.h' using translations from Crowdin.
Both v1 and v2 structs are supported. It is, however, recommended to convert v1 files to v2 using the included
'v1_to_v2_converter.py'.
Usage:
python3 path/to/core_option_translation.py "path/to/where/libretro_core_options.h & libretro_core_options_intl.h/are" "core_name"
This script will:
1.) create key words for & extract the texts from libretro_core_options.h & save them into intl/_us/core_options.h
2.) do the same for any present translations in libretro_core_options_intl.h, saving those in their respective folder

Frequently Asked Questions about zlib
If your question is not there, please check the zlib home page
http://zlib.net/ which may have more recent information.
The lastest zlib FAQ is at http://zlib.net/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://zlib.net/ .
3. Where can I get a Visual Basic interface to zlib?
See
* http://marknelson.us/1997/01/01/zlib-engine/
* 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 available 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. See http://zlib.net/zlib_how.html for a
heavily annotated example.
6. Where's the zlib documentation (man pages, etc.)?
It's in zlib.h . Examples of zlib usage are in the files test/example.c
and test/minigzip.c, with more in examples/ .
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?
By default a shared (and a static) library is built for Unix. So:
make distclean
./configure
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. You can check the version at the top of zlib.h or with the
ZLIB_VERSION symbol defined in zlib.h .
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.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?
Yes. 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. Alternatively, you can scan a
deflate stream once to generate an index, and then use that index for
random access. See examples/zran.c .
29. Does zlib work on MVS, OS/390, CICS, etc.?
It has in the past, but we have not heard of any recent evidence. There
were working ports of zlib 1.1.4 to MVS, but those links no longer work.
If you know of recent, successful applications of zlib on these operating
systems, please let us know. 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 an 8K string space (or other value as set by
gzbuffer()), other than the caller of gzprintf() assuring that the output
will not exceed 8K. 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, and versions
1.2.1 and 1.2.2 were subject to an access exception when decompressing
invalid compressed data.
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://zlib.net/ .
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 as well as contradicted each other. 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. Even though the code was
correct, versions 1.2.4 and later was changed to not stimulate these
checkers.
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
specification 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. I'm having a problem with the zip functions in zlib, can you help?
There are no zip functions in zlib. You are probably using minizip by
Giles Vollant, which is found in the contrib directory of zlib. It is not
part of zlib. In fact none of the stuff in contrib is part of zlib. The
files in there are not supported by the zlib authors. You need to contact
the authors of the respective contribution for help.
42. The match.asm code in contrib is under the GNU General Public License.
Since it's part of zlib, doesn't that mean that all of zlib falls under the
GNU GPL?
No. The files in contrib are not part of zlib. They were contributed by
other authors and are provided as a convenience to the user within the zlib
distribution. Each item in contrib has its own license.
43. Is zlib subject to export controls? What is its ECCN?
zlib is not subject to export controls, and so is classified as EAR99.
44. 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.

# If you want to build just a static library, use: ./configure --static
#
# To impose specific compiler or flags or install directory, use for example:
# prefix=$HOME CC=cc CFLAGS="-O4" ./configure
# or for csh/tcsh users:
# (setenv prefix $HOME; setenv CC cc; setenv CFLAGS "-O4"; ./configure)
# Incorrect settings of CC or CFLAGS may prevent creating a shared library.
# If you have problems, try without defining CC and CFLAGS before reporting
# an error.

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 too 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.

Abstract
This specification defines a lossless compressed data format. The
data can be produced or consumed, even for an arbitrarily long
sequentially presented input data stream, using only an a priori
bounded amount of intermediate storage. The format presently uses
the DEFLATE compression method but can be easily extended to use
other compression methods. It can be implemented readily in a manner
not covered by patents. This specification also defines the ADLER-32
checksum (an extension and improvement of the Fletcher checksum),
used for detection of data corruption, and provides an algorithm for
computing it.

1. Introduction
1.1. Purpose
The purpose of this specification is to define a lossless
compressed data format that:
* Is independent of CPU type, operating system, file system,
and character set, and hence can be used for interchange;
* Can be produced or consumed, even for an arbitrarily long
sequentially presented input data stream, using only an a
priori bounded amount of intermediate storage, and hence can
be used in data communications or similar structures such as
Unix filters;
* Can use a number of different compression methods;
* Can be implemented readily in a manner not covered by
patents, and hence can be practiced freely.
The data format defined by this specification does not attempt to
allow random access to compressed data.
Deutsch & Gailly Informational [Page 2]
RFC 1950 ZLIB Compressed Data Format Specification May 1996
1.2. Intended audience
This specification is intended for use by implementors of software
to compress data into zlib format and/or decompress data from zlib
format.
The text of the specification assumes a basic background in
programming at the level of bits and other primitive data
representations.
1.3. Scope
The specification specifies a compressed data format that can be
used for in-memory compression of a sequence of arbitrary bytes.
1.4. Compliance
Unless otherwise indicated below, a compliant decompressor must be
able to accept and decompress any data set that conforms to all
the specifications presented here; a compliant compressor must
produce data sets that conform to all the specifications presented
here.
1.5. Definitions of terms and conventions used
byte: 8 bits stored or transmitted as a unit (same as an octet).
(For this specification, a byte is exactly 8 bits, even on
machines which store a character on a number of bits different
from 8.) See below, for the numbering of bits within a byte.
1.6. Changes from previous versions
Version 3.1 was the first public release of this specification.
In version 3.2, some terminology was changed and the Adler-32
sample code was rewritten for clarity. In version 3.3, the
support for a preset dictionary was introduced, and the
specification was converted to RFC style.
2. Detailed specification
2.1. Overall conventions
In the diagrams below, a box like this:
+---+
| | <-- the vertical bars might be missing
+---+
Deutsch & Gailly Informational [Page 3]
RFC 1950 ZLIB Compressed Data Format Specification May 1996
represents one byte; a box like this:
+==============+
| |
+==============+
represents a variable number of bytes.
Bytes stored within a computer do not have a "bit order", since
they are always treated as a unit. However, a byte considered as
an integer between 0 and 255 does have a most- and least-
significant bit, and since we write numbers with the most-
significant digit on the left, we also write bytes with the most-
significant bit on the left. In the diagrams below, we number the
bits of a byte so that bit 0 is the least-significant bit, i.e.,
the bits are numbered:
+--------+
|76543210|
+--------+
Within a computer, a number may occupy multiple bytes. All
multi-byte numbers in the format described here are stored with
the MOST-significant byte first (at the lower memory address).
For example, the decimal number 520 is stored as:
0 1
+--------+--------+
|00000010|00001000|
+--------+--------+
^ ^
| |
| + less significant byte = 8
+ more significant byte = 2 x 256
2.2. Data format
A zlib stream has the following structure:
0 1
+---+---+
|CMF|FLG| (more-->)
+---+---+
Deutsch & Gailly Informational [Page 4]
RFC 1950 ZLIB Compressed Data Format Specification May 1996
(if FLG.FDICT set)
0 1 2 3
+---+---+---+---+
| DICTID | (more-->)
+---+---+---+---+
+=====================+---+---+---+---+
|...compressed data...| ADLER32 |
+=====================+---+---+---+---+
Any data which may appear after ADLER32 are not part of the zlib
stream.
CMF (Compression Method and flags)
This byte is divided into a 4-bit compression method and a 4-
bit information field depending on the compression method.
bits 0 to 3 CM Compression method
bits 4 to 7 CINFO Compression info
CM (Compression method)
This identifies the compression method used in the file. CM = 8
denotes the "deflate" compression method with a window size up
to 32K. This is the method used by gzip and PNG (see
references [1] and [2] in Chapter 3, below, for the reference
documents). CM = 15 is reserved. It might be used in a future
version of this specification to indicate the presence of an
extra field before the compressed data.
CINFO (Compression info)
For CM = 8, CINFO is the base-2 logarithm of the LZ77 window
size, minus eight (CINFO=7 indicates a 32K window size). Values
of CINFO above 7 are not allowed in this version of the
specification. CINFO is not defined in this specification for
CM not equal to 8.
FLG (FLaGs)
This flag byte is divided as follows:
bits 0 to 4 FCHECK (check bits for CMF and FLG)
bit 5 FDICT (preset dictionary)
bits 6 to 7 FLEVEL (compression level)
The FCHECK value must be such that CMF and FLG, when viewed as
a 16-bit unsigned integer stored in MSB order (CMF*256 + FLG),
is a multiple of 31.
Deutsch & Gailly Informational [Page 5]
RFC 1950 ZLIB Compressed Data Format Specification May 1996
FDICT (Preset dictionary)
If FDICT is set, a DICT dictionary identifier is present
immediately after the FLG byte. The dictionary is a sequence of
bytes which are initially fed to the compressor without
producing any compressed output. DICT is the Adler-32 checksum
of this sequence of bytes (see the definition of ADLER32
below). The decompressor can use this identifier to determine
which dictionary has been used by the compressor.
FLEVEL (Compression level)
These flags are available for use by specific compression
methods. The "deflate" method (CM = 8) sets these flags as
follows:
0 - compressor used fastest algorithm
1 - compressor used fast algorithm
2 - compressor used default algorithm
3 - compressor used maximum compression, slowest algorithm
The information in FLEVEL is not needed for decompression; it
is there to indicate if recompression might be worthwhile.
compressed data
For compression method 8, the compressed data is stored in the
deflate compressed data format as described in the document
"DEFLATE Compressed Data Format Specification" by L. Peter
Deutsch. (See reference [3] in Chapter 3, below)
Other compressed data formats are not specified in this version
of the zlib specification.
ADLER32 (Adler-32 checksum)
This contains a checksum value of the uncompressed data
(excluding any dictionary data) computed according to Adler-32
algorithm. This algorithm is a 32-bit extension and improvement
of the Fletcher algorithm, used in the ITU-T X.224 / ISO 8073
standard. See references [4] and [5] in Chapter 3, below)
Adler-32 is composed of two sums accumulated per byte: s1 is
the sum of all bytes, s2 is the sum of all s1 values. Both sums
are done modulo 65521. s1 is initialized to 1, s2 to zero. The
Adler-32 checksum is stored as s2*65536 + s1 in most-
significant-byte first (network) order.
Deutsch & Gailly Informational [Page 6]
RFC 1950 ZLIB Compressed Data Format Specification May 1996
2.3. Compliance
A compliant compressor must produce streams with correct CMF, FLG
and ADLER32, but need not support preset dictionaries. When the
zlib data format is used as part of another standard data format,
the compressor may use only preset dictionaries that are specified
by this other data format. If this other format does not use the
preset dictionary feature, the compressor must not set the FDICT
flag.
A compliant decompressor must check CMF, FLG, and ADLER32, and
provide an error indication if any of these have incorrect values.
A compliant decompressor must give an error indication if CM is
not one of the values defined in this specification (only the
value 8 is permitted in this version), since another value could
indicate the presence of new features that would cause subsequent
data to be interpreted incorrectly. A compliant decompressor must
give an error indication if FDICT is set and DICTID is not the
identifier of a known preset dictionary. A decompressor may
ignore FLEVEL and still be compliant. When the zlib data format
is being used as a part of another standard format, a compliant
decompressor must support all the preset dictionaries specified by
the other format. When the other format does not use the preset
dictionary feature, a compliant decompressor must reject any
stream in which the FDICT flag is set.

8. Appendix: Rationale
8.1. Preset dictionaries
A preset dictionary is specially useful to compress short input
sequences. The compressor can take advantage of the dictionary
context to encode the input in a more compact manner. The
decompressor can be initialized with the appropriate context by
virtually decompressing a compressed version of the dictionary
without producing any output. However for certain compression
algorithms such as the deflate algorithm this operation can be
achieved without actually performing any decompression.
The compressor and the decompressor must use exactly the same
dictionary. The dictionary may be fixed or may be chosen among a
certain number of predefined dictionaries, according to the kind
of input data. The decompressor can determine which dictionary has
been chosen by the compressor by checking the dictionary
identifier. This document does not specify the contents of
predefined dictionaries, since the optimal dictionaries are
application specific. Standard data formats using this feature of
the zlib specification must precisely define the allowed
dictionaries.
8.2. The Adler-32 algorithm
The Adler-32 algorithm is much faster than the CRC32 algorithm yet
still provides an extremely low probability of undetected errors.
The modulo on unsigned long accumulators can be delayed for 5552
bytes, so the modulo operation time is negligible. If the bytes
are a, b, c, the second sum is 3a + 2b + c + 3, and so is position
and order sensitive, unlike the first sum, which is just a
checksum. That 65521 is prime is important to avoid a possible
large class of two-byte errors that leave the check unchanged.
(The Fletcher checksum uses 255, which is not prime and which also
makes the Fletcher check insensitive to single byte changes 0 <->
255.)
The sum s1 is initialized to 1 instead of zero to make the length
of the sequence part of s2, so that the length does not have to be
checked separately. (Any sequence of zeroes has a Fletcher
checksum of zero.)
Deutsch & Gailly Informational [Page 9]
RFC 1950 ZLIB Compressed Data Format Specification May 1996
9. Appendix: Sample code
The following C code computes the Adler-32 checksum of a data buffer.
It is written for clarity, not for speed. The sample code is in the
ANSI C programming language. Non C users may find it easier to read
with these hints:
& Bitwise AND operator.
>> Bitwise right shift operator. When applied to an
unsigned quantity, as here, right shift inserts zero bit(s)
at the left.
<< Bitwise left shift operator. Left shift inserts zero
bit(s) at the right.
++ "n++" increments the variable n.
% modulo operator: a % b is the remainder of a divided by b.
#define BASE 65521 /* largest prime smaller than 65536 */
/*
Update a running Adler-32 checksum with the bytes buf[0..len-1]
and return the updated checksum. The Adler-32 checksum should be
initialized to 1.
Usage example:
unsigned long adler = 1L;
while (read_buffer(buffer, length) != EOF) {
adler = update_adler32(adler, buffer, length);
}
if (adler != original_adler) error();
*/
unsigned long update_adler32(unsigned long adler,
unsigned char *buf, int len)
{
unsigned long s1 = adler & 0xffff;
unsigned long s2 = (adler >> 16) & 0xffff;
int n;
for (n = 0; n < len; n++) {
s1 = (s1 + buf[n]) % BASE;
s2 = (s2 + s1) % BASE;
}
return (s2 << 16) + s1;
}
/* Return the adler32 of the bytes buf[0..len-1] */

Abstract
This specification defines a lossless compressed data format that
compresses data using a combination of the LZ77 algorithm and Huffman
coding, with efficiency comparable to the best currently available
general-purpose compression methods. The data can be produced or
consumed, even for an arbitrarily long sequentially presented input
data stream, using only an a priori bounded amount of intermediate
storage. The format can be implemented readily in a manner not
covered by patents.

1. Introduction
1.1. Purpose
The purpose of this specification is to define a lossless
compressed data format that:
* Is independent of CPU type, operating system, file system,
and character set, and hence can be used for interchange;
* Can be produced or consumed, even for an arbitrarily long
sequentially presented input data stream, using only an a
priori bounded amount of intermediate storage, and hence
can be used in data communications or similar structures
such as Unix filters;
* Compresses data with efficiency comparable to the best
currently available general-purpose compression methods,
and in particular considerably better than the "compress"
program;
* Can be implemented readily in a manner not covered by
patents, and hence can be practiced freely;
Deutsch Informational [Page 2]
RFC 1951 DEFLATE Compressed Data Format Specification May 1996
* Is compatible with the file format produced by the current
widely used gzip utility, in that conforming decompressors
will be able to read data produced by the existing gzip
compressor.
The data format defined by this specification does not attempt to:
* Allow random access to compressed data;
* Compress specialized data (e.g., raster graphics) as well
as the best currently available specialized algorithms.
A simple counting argument shows that no lossless compression
algorithm can compress every possible input data set. For the
format defined here, the worst case expansion is 5 bytes per 32K-
byte block, i.e., a size increase of 0.015% for large data sets.
English text usually compresses by a factor of 2.5 to 3;
executable files usually compress somewhat less; graphical data
such as raster images may compress much more.
1.2. Intended audience
This specification is intended for use by implementors of software
to compress data into "deflate" format and/or decompress data from
"deflate" format.
The text of the specification assumes a basic background in
programming at the level of bits and other primitive data
representations. Familiarity with the technique of Huffman coding
is helpful but not required.
1.3. Scope
The specification specifies a method for representing a sequence
of bytes as a (usually shorter) sequence of bits, and a method for
packing the latter bit sequence into bytes.
1.4. Compliance
Unless otherwise indicated below, a compliant decompressor must be
able to accept and decompress any data set that conforms to all
the specifications presented here; a compliant compressor must
produce data sets that conform to all the specifications presented
here.
1.5. Definitions of terms and conventions used
Byte: 8 bits stored or transmitted as a unit (same as an octet).
For this specification, a byte is exactly 8 bits, even on machines
Deutsch Informational [Page 3]
RFC 1951 DEFLATE Compressed Data Format Specification May 1996
which store a character on a number of bits different from eight.
See below, for the numbering of bits within a byte.
String: a sequence of arbitrary bytes.
1.6. Changes from previous versions
There have been no technical changes to the deflate format since
version 1.1 of this specification. In version 1.2, some
terminology was changed. Version 1.3 is a conversion of the
specification to RFC style.
2. Compressed representation overview
A compressed data set consists of a series of blocks, corresponding
to successive blocks of input data. The block sizes are arbitrary,
except that non-compressible blocks are limited to 65,535 bytes.
Each block is compressed using a combination of the LZ77 algorithm
and Huffman coding. The Huffman trees for each block are independent
of those for previous or subsequent blocks; the LZ77 algorithm may
use a reference to a duplicated string occurring in a previous block,
up to 32K input bytes before.
Each block consists of two parts: a pair of Huffman code trees that
describe the representation of the compressed data part, and a
compressed data part. (The Huffman trees themselves are compressed
using Huffman encoding.) The compressed data consists of a series of
elements of two types: literal bytes (of strings that have not been
detected as duplicated within the previous 32K input bytes), and
pointers to duplicated strings, where a pointer is represented as a
pair <length, backward distance>. The representation used in the
"deflate" format limits distances to 32K bytes and lengths to 258
bytes, but does not limit the size of a block, except for
uncompressible blocks, which are limited as noted above.
Each type of value (literals, distances, and lengths) in the
compressed data is represented using a Huffman code, using one code
tree for literals and lengths and a separate code tree for distances.
The code trees for each block appear in a compact form just before
the compressed data for that block.

3. Detailed specification
3.1. Overall conventions In the diagrams below, a box like this:
+---+
| | <-- the vertical bars might be missing
+---+
represents one byte; a box like this:
+==============+
| |
+==============+
represents a variable number of bytes.
Bytes stored within a computer do not have a "bit order", since
they are always treated as a unit. However, a byte considered as
an integer between 0 and 255 does have a most- and least-
significant bit, and since we write numbers with the most-
significant digit on the left, we also write bytes with the most-
significant bit on the left. In the diagrams below, we number the
bits of a byte so that bit 0 is the least-significant bit, i.e.,
the bits are numbered:
+--------+
|76543210|
+--------+
Within a computer, a number may occupy multiple bytes. All
multi-byte numbers in the format described here are stored with
the least-significant byte first (at the lower memory address).
For example, the decimal number 520 is stored as:
0 1
+--------+--------+
|00001000|00000010|
+--------+--------+
^ ^
| |
| + more significant byte = 2 x 256
+ less significant byte = 8
3.1.1. Packing into bytes
This document does not address the issue of the order in which
bits of a byte are transmitted on a bit-sequential medium,
since the final data format described here is byte- rather than
Deutsch Informational [Page 5]
RFC 1951 DEFLATE Compressed Data Format Specification May 1996
bit-oriented. However, we describe the compressed block format
in below, as a sequence of data elements of various bit
lengths, not a sequence of bytes. We must therefore specify
how to pack these data elements into bytes to form the final
compressed byte sequence:
* Data elements are packed into bytes in order of
increasing bit number within the byte, i.e., starting
with the least-significant bit of the byte.
* Data elements other than Huffman codes are packed
starting with the least-significant bit of the data
element.
* Huffman codes are packed starting with the most-
significant bit of the code.
In other words, if one were to print out the compressed data as
a sequence of bytes, starting with the first byte at the
*right* margin and proceeding to the *left*, with the most-
significant bit of each byte on the left as usual, one would be
able to parse the result from right to left, with fixed-width
elements in the correct MSB-to-LSB order and Huffman codes in
bit-reversed order (i.e., with the first bit of the code in the
relative LSB position).
3.2. Compressed block format
3.2.1. Synopsis of prefix and Huffman coding
Prefix coding represents symbols from an a priori known
alphabet by bit sequences (codes), one code for each symbol, in
a manner such that different symbols may be represented by bit
sequences of different lengths, but a parser can always parse
an encoded string unambiguously symbol-by-symbol.
We define a prefix code in terms of a binary tree in which the
two edges descending from each non-leaf node are labeled 0 and
1 and in which the leaf nodes correspond one-for-one with (are
labeled with) the symbols of the alphabet; then the code for a
symbol is the sequence of 0's and 1's on the edges leading from
the root to the leaf labeled with that symbol. For example:
Deutsch Informational [Page 6]
RFC 1951 DEFLATE Compressed Data Format Specification May 1996
/\ Symbol Code
0 1 ------ ----
/ \ A 00
/\ B B 1
0 1 C 011
/ \ D 010
A /\
0 1
/ \
D C
A parser can decode the next symbol from an encoded input
stream by walking down the tree from the root, at each step
choosing the edge corresponding to the next input bit.
Given an alphabet with known symbol frequencies, the Huffman
algorithm allows the construction of an optimal prefix code
(one which represents strings with those symbol frequencies
using the fewest bits of any possible prefix codes for that
alphabet). Such a code is called a Huffman code. (See
reference [1] in Chapter 5, references for additional
information on Huffman codes.)
Note that in the "deflate" format, the Huffman codes for the
various alphabets must not exceed certain maximum code lengths.
This constraint complicates the algorithm for computing code
lengths from symbol frequencies. Again, see Chapter 5,
references for details.
3.2.2. Use of Huffman coding in the "deflate" format
The Huffman codes used for each alphabet in the "deflate"
format have two additional rules:
* All codes of a given bit length have lexicographically
consecutive values, in the same order as the symbols
they represent;
* Shorter codes lexicographically precede longer codes.
Deutsch Informational [Page 7]
RFC 1951 DEFLATE Compressed Data Format Specification May 1996
We could recode the example above to follow this rule as
follows, assuming that the order of the alphabet is ABCD:
Symbol Code
------ ----
A 10
B 0
C 110
D 111
I.e., 0 precedes 10 which precedes 11x, and 110 and 111 are
lexicographically consecutive.
Given this rule, we can define the Huffman code for an alphabet
just by giving the bit lengths of the codes for each symbol of
the alphabet in order; this is sufficient to determine the
actual codes. In our example, the code is completely defined
by the sequence of bit lengths (2, 1, 3, 3). The following
algorithm generates the codes as integers, intended to be read
from most- to least-significant bit. The code lengths are
initially in tree[I].Len; the codes are produced in
tree[I].Code.
1) Count the number of codes for each code length. Let
bl_count[N] be the number of codes of length N, N >= 1.
2) Find the numerical value of the smallest code for each
code length:
code = 0;
bl_count[0] = 0;
for (bits = 1; bits <= MAX_BITS; bits++) {
code = (code + bl_count[bits-1]) << 1;
next_code[bits] = code;
}
3) Assign numerical values to all codes, using consecutive
values for all codes of the same length with the base
values determined at step 2. Codes that are never used
(which have a bit length of zero) must not be assigned a
value.
for (n = 0; n <= max_code; n++) {
len = tree[n].Len;
if (len != 0) {
tree[n].Code = next_code[len];
next_code[len]++;
}
Deutsch Informational [Page 8]
RFC 1951 DEFLATE Compressed Data Format Specification May 1996
}
Example:
Consider the alphabet ABCDEFGH, with bit lengths (3, 3, 3, 3,
3, 2, 4, 4). After step 1, we have:
N bl_count[N]
- -----------
2 1
3 5
4 2
Step 2 computes the following next_code values:
N next_code[N]
- ------------
1 0
2 0
3 2
4 14
Step 3 produces the following code values:
Symbol Length Code
------ ------ ----
A 3 010
B 3 011
C 3 100
D 3 101
E 3 110
F 2 00
G 4 1110
H 4 1111
3.2.3. Details of block format
Each block of compressed data begins with 3 header bits
containing the following data:
first bit BFINAL
next 2 bits BTYPE
Note that the header bits do not necessarily begin on a byte
boundary, since a block does not necessarily occupy an integral
number of bytes.
Deutsch Informational [Page 9]
RFC 1951 DEFLATE Compressed Data Format Specification May 1996
BFINAL is set if and only if this is the last block of the data
set.
BTYPE specifies how the data are compressed, as follows:
00 - no compression
01 - compressed with fixed Huffman codes
10 - compressed with dynamic Huffman codes
11 - reserved (error)
The only difference between the two compressed cases is how the
Huffman codes for the literal/length and distance alphabets are
defined.
In all cases, the decoding algorithm for the actual data is as
follows:
do
read block header from input stream.
if stored with no compression
skip any remaining bits in current partially
processed byte
read LEN and NLEN (see next section)
copy LEN bytes of data to output
otherwise
if compressed with dynamic Huffman codes
read representation of code trees (see
subsection below)
loop (until end of block code recognized)
decode literal/length value from input stream
if value < 256
copy value (literal byte) to output stream
otherwise
if value = end of block (256)
break from loop
otherwise (value = 257..285)
decode distance from input stream
move backwards distance bytes in the output
stream, and copy length bytes from this
position to the output stream.
end loop
while not last block
Note that a duplicated string reference may refer to a string
in a previous block; i.e., the backward distance may cross one
or more block boundaries. However a distance cannot refer past
the beginning of the output stream. (An application using a
Deutsch Informational [Page 10]
RFC 1951 DEFLATE Compressed Data Format Specification May 1996
preset dictionary might discard part of the output stream; a
distance can refer to that part of the output stream anyway)
Note also that the referenced string may overlap the current
position; for example, if the last 2 bytes decoded have values
X and Y, a string reference with <length = 5, distance = 2>
adds X,Y,X,Y,X to the output stream.
We now specify each compression method in turn.
3.2.4. Non-compressed blocks (BTYPE=00)
Any bits of input up to the next byte boundary are ignored.
The rest of the block consists of the following information:
0 1 2 3 4...
+---+---+---+---+================================+
| LEN | NLEN |... LEN bytes of literal data...|
+---+---+---+---+================================+
LEN is the number of data bytes in the block. NLEN is the
one's complement of LEN.
3.2.5. Compressed blocks (length and distance codes)
As noted above, encoded data blocks in the "deflate" format
consist of sequences of symbols drawn from three conceptually
distinct alphabets: either literal bytes, from the alphabet of
byte values (0..255), or <length, backward distance> pairs,
where the length is drawn from (3..258) and the distance is
drawn from (1..32,768). In fact, the literal and length
alphabets are merged into a single alphabet (0..285), where
values 0..255 represent literal bytes, the value 256 indicates
end-of-block, and values 257..285 represent length codes
(possibly in conjunction with extra bits following the symbol
code) as follows:
Deutsch Informational [Page 11]
RFC 1951 DEFLATE Compressed Data Format Specification May 1996
Extra Extra Extra

266 1 13,14 276 3 59-66
The extra bits should be interpreted as a machine integer
stored with the most-significant bit first, e.g., bits 1110
represent the value 14.

3.2.6. Compression with fixed Huffman codes (BTYPE=01)
The Huffman codes for the two alphabets are fixed, and are not
represented explicitly in the data. The Huffman code lengths
for the literal/length alphabet are:
Lit Value Bits Codes
--------- ---- -----
0 - 143 8 00110000 through
10111111
144 - 255 9 110010000 through
111111111
256 - 279 7 0000000 through
0010111
280 - 287 8 11000000 through
11000111
Deutsch Informational [Page 12]
RFC 1951 DEFLATE Compressed Data Format Specification May 1996
The code lengths are sufficient to generate the actual codes,
as described above; we show the codes in the table for added
clarity. Literal/length values 286-287 will never actually
occur in the compressed data, but participate in the code
construction.
Distance codes 0-31 are represented by (fixed-length) 5-bit
codes, with possible additional bits as shown in the table
shown in Paragraph 3.2.5, above. Note that distance codes 30-
31 will never actually occur in the compressed data.
3.2.7. Compression with dynamic Huffman codes (BTYPE=10)
The Huffman codes for the two alphabets appear in the block
immediately after the header bits and before the actual
compressed data, first the literal/length code and then the
distance code. Each code is defined by a sequence of code
lengths, as discussed in Paragraph 3.2.2, above. For even
greater compactness, the code length sequences themselves are
compressed using a Huffman code. The alphabet for code lengths
is as follows:
0 - 15: Represent code lengths of 0 - 15
16: Copy the previous code length 3 - 6 times.
The next 2 bits indicate repeat length
(0 = 3, ... , 3 = 6)
Example: Codes 8, 16 (+2 bits 11),
16 (+2 bits 10) will expand to
12 code lengths of 8 (1 + 6 + 5)
17: Repeat a code length of 0 for 3 - 10 times.
(3 bits of length)
18: Repeat a code length of 0 for 11 - 138 times
(7 bits of length)
A code length of 0 indicates that the corresponding symbol in
the literal/length or distance alphabet will not occur in the
block, and should not participate in the Huffman code
construction algorithm given earlier. If only one distance
code is used, it is encoded using one bit, not zero bits; in
this case there is a single code length of one, with one unused
code. One distance code of zero bits means that there are no
distance codes used at all (the data is all literals).
We can now define the format of the block:
5 Bits: HLIT, # of Literal/Length codes - 257 (257 - 286)
5 Bits: HDIST, # of Distance codes - 1 (1 - 32)
4 Bits: HCLEN, # of Code Length codes - 4 (4 - 19)
Deutsch Informational [Page 13]
RFC 1951 DEFLATE Compressed Data Format Specification May 1996
(HCLEN + 4) x 3 bits: code lengths for the code length
alphabet given just above, in the order: 16, 17, 18,
0, 8, 7, 9, 6, 10, 5, 11, 4, 12, 3, 13, 2, 14, 1, 15
These code lengths are interpreted as 3-bit integers
(0-7); as above, a code length of 0 means the
corresponding symbol (literal/length or distance code
length) is not used.
HLIT + 257 code lengths for the literal/length alphabet,
encoded using the code length Huffman code
HDIST + 1 code lengths for the distance alphabet,
encoded using the code length Huffman code
The actual compressed data of the block,
encoded using the literal/length and distance Huffman
codes
The literal/length symbol 256 (end of data),
encoded using the literal/length Huffman code
The code length repeat codes can cross from HLIT + 257 to the
HDIST + 1 code lengths. In other words, all code lengths form
a single sequence of HLIT + HDIST + 258 values.
3.3. Compliance
A compressor may limit further the ranges of values specified in
the previous section and still be compliant; for example, it may
limit the range of backward pointers to some value smaller than
32K. Similarly, a compressor may limit the size of blocks so that
a compressible block fits in memory.
A compliant decompressor must accept the full range of possible
values defined in the previous section, and must accept blocks of
arbitrary size.
4. Compression algorithm details
While it is the intent of this document to define the "deflate"
compressed data format without reference to any particular
compression algorithm, the format is related to the compressed
formats produced by LZ77 (Lempel-Ziv 1977, see reference [2] below);
since many variations of LZ77 are patented, it is strongly
recommended that the implementor of a compressor follow the general
algorithm presented here, which is known not to be patented per se.
The material in this section is not part of the definition of the
Deutsch Informational [Page 14]
RFC 1951 DEFLATE Compressed Data Format Specification May 1996
specification per se, and a compressor need not follow it in order to
be compliant.
The compressor terminates a block when it determines that starting a
new block with fresh trees would be useful, or when the block size
fills up the compressor's block buffer.
The compressor uses a chained hash table to find duplicated strings,
using a hash function that operates on 3-byte sequences. At any
given point during compression, let XYZ be the next 3 input bytes to
be examined (not necessarily all different, of course). First, the
compressor examines the hash chain for XYZ. If the chain is empty,
the compressor simply writes out X as a literal byte and advances one
byte in the input. If the hash chain is not empty, indicating that
the sequence XYZ (or, if we are unlucky, some other 3 bytes with the
same hash function value) has occurred recently, the compressor
compares all strings on the XYZ hash chain with the actual input data
sequence starting at the current point, and selects the longest
match.
The compressor searches the hash chains 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
run-time parameter.
To improve overall compression, the compressor optionally defers the
selection of matches ("lazy matching"): after a match of length N has
been found, the compressor searches for a longer match starting at
the next input byte. If it finds a longer match, it truncates the
previous match to a length of one (thus producing a single literal
byte) and then emits the longer match. Otherwise, it emits the
original match, and, as described above, advances N bytes before
continuing.
Run-time parameters also control this "lazy match" procedure. If
compression ratio is most important, the compressor attempts a
complete second search regardless of the length of the first match.
In the normal case, if the current match is "long enough", the
compressor reduces the search for a longer match, thus speeding up
the process. If speed is most important, the compressor inserts new
strings 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.

6. Security Considerations
Any data compression method involves the reduction of redundancy in
the data. Consequently, any corruption of the data is likely to have
severe effects and be difficult to correct. Uncompressed text, on
the other hand, will probably still be readable despite the presence
of some corrupted bytes.
It is recommended that systems using this data format provide some
means of validating the integrity of the compressed data. See
reference [3], for example.

Abstract
This specification defines a lossless compressed data format that is
compatible with the widely used GZIP utility. The format includes a
cyclic redundancy check value for detecting data corruption. The
format presently uses the DEFLATE method of compression but can be
easily extended to use other compression methods. The format can be
implemented readily in a manner not covered by patents.

1. Introduction
1.1. Purpose
The purpose of this specification is to define a lossless
compressed data format that:
* Is independent of CPU type, operating system, file system,
and character set, and hence can be used for interchange;
* Can compress or decompress a data stream (as opposed to a
randomly accessible file) to produce another data stream,
using only an a priori bounded amount of intermediate
storage, and hence can be used in data communications or
similar structures such as Unix filters;
* Compresses data with efficiency comparable to the best
currently available general-purpose compression methods,
and in particular considerably better than the "compress"
program;
* Can be implemented readily in a manner not covered by
patents, and hence can be practiced freely;
* Is compatible with the file format produced by the current
widely used gzip utility, in that conforming decompressors
will be able to read data produced by the existing gzip
compressor.
Deutsch Informational [Page 2]
RFC 1952 GZIP File Format Specification May 1996
The data format defined by this specification does not attempt to:
* Provide random access to compressed data;
* Compress specialized data (e.g., raster graphics) as well as
the best currently available specialized algorithms.
1.2. Intended audience
This specification is intended for use by implementors of software
to compress data into gzip format and/or decompress data from gzip
format.
The text of the specification assumes a basic background in
programming at the level of bits and other primitive data
representations.
1.3. Scope
The specification specifies a compression method and a file format
(the latter assuming only that a file can store a sequence of
arbitrary bytes). It does not specify any particular interface to
a file system or anything about character sets or encodings
(except for file names and comments, which are optional).
1.4. Compliance
Unless otherwise indicated below, a compliant decompressor must be
able to accept and decompress any file that conforms to all the
specifications presented here; a compliant compressor must produce
files that conform to all the specifications presented here. The
material in the appendices is not part of the specification per se
and is not relevant to compliance.
1.5. Definitions of terms and conventions used
byte: 8 bits stored or transmitted as a unit (same as an octet).
(For this specification, a byte is exactly 8 bits, even on
machines which store a character on a number of bits different
from 8.) See below for the numbering of bits within a byte.
1.6. Changes from previous versions
There have been no technical changes to the gzip format since
version 4.1 of this specification. In version 4.2, some
terminology was changed, and the sample CRC code was rewritten for
clarity and to eliminate the requirement for the caller to do pre-
and post-conditioning. Version 4.3 is a conversion of the
specification to RFC style.
Deutsch Informational [Page 3]
RFC 1952 GZIP File Format Specification May 1996
2. Detailed specification
2.1. Overall conventions
In the diagrams below, a box like this:
+---+
| | <-- the vertical bars might be missing
+---+
represents one byte; a box like this:
+==============+
| |
+==============+
represents a variable number of bytes.
Bytes stored within a computer do not have a "bit order", since
they are always treated as a unit. However, a byte considered as
an integer between 0 and 255 does have a most- and least-
significant bit, and since we write numbers with the most-
significant digit on the left, we also write bytes with the most-
significant bit on the left. In the diagrams below, we number the
bits of a byte so that bit 0 is the least-significant bit, i.e.,
the bits are numbered:
+--------+
|76543210|
+--------+
This document does not address the issue of the order in which
bits of a byte are transmitted on a bit-sequential medium, since
the data format described here is byte- rather than bit-oriented.
Within a computer, a number may occupy multiple bytes. All
multi-byte numbers in the format described here are stored with
the least-significant byte first (at the lower memory address).
For example, the decimal number 520 is stored as:
0 1
+--------+--------+
|00001000|00000010|
+--------+--------+
^ ^
| |
| + more significant byte = 2 x 256
+ less significant byte = 8
Deutsch Informational [Page 4]
RFC 1952 GZIP File Format Specification May 1996
2.2. File format
A gzip file consists of a series of "members" (compressed data
sets). The format of each member is specified in the following
section. The members simply appear one after another in the file,
with no additional information before, between, or after them.
2.3. Member format
Each member has the following structure:
+---+---+---+---+---+---+---+---+---+---+
|ID1|ID2|CM |FLG| MTIME |XFL|OS | (more-->)
+---+---+---+---+---+---+---+---+---+---+
(if FLG.FEXTRA set)
+---+---+=================================+
| XLEN |...XLEN bytes of "extra field"...| (more-->)
+---+---+=================================+
(if FLG.FNAME set)
+=========================================+
|...original file name, zero-terminated...| (more-->)
+=========================================+
(if FLG.FCOMMENT set)
+===================================+
|...file comment, zero-terminated...| (more-->)
+===================================+
(if FLG.FHCRC set)
+---+---+
| CRC16 |
+---+---+
+=======================+
|...compressed blocks...| (more-->)
+=======================+
0 1 2 3 4 5 6 7
+---+---+---+---+---+---+---+---+
| CRC32 | ISIZE |
+---+---+---+---+---+---+---+---+
Deutsch Informational [Page 5]
RFC 1952 GZIP File Format Specification May 1996
2.3.1. Member header and trailer
ID1 (IDentification 1)
ID2 (IDentification 2)
These have the fixed values ID1 = 31 (0x1f, \037), ID2 = 139
(0x8b, \213), to identify the file as being in gzip format.
CM (Compression Method)
This identifies the compression method used in the file. CM
= 0-7 are reserved. CM = 8 denotes the "deflate"
compression method, which is the one customarily used by
gzip and which is documented elsewhere.
FLG (FLaGs)
This flag byte is divided into individual bits as follows:
bit 0 FTEXT
bit 1 FHCRC
bit 2 FEXTRA
bit 3 FNAME
bit 4 FCOMMENT
bit 5 reserved
bit 6 reserved
bit 7 reserved
If FTEXT is set, the file is probably ASCII text. This is
an optional indication, which the compressor may set by
checking a small amount of the input data to see whether any
non-ASCII characters are present. In case of doubt, FTEXT
is cleared, indicating binary data. For systems which have
different file formats for ascii text and binary data, the
decompressor can use FTEXT to choose the appropriate format.
We deliberately do not specify the algorithm used to set
this bit, since a compressor always has the option of
leaving it cleared and a decompressor always has the option
of ignoring it and letting some other program handle issues
of data conversion.
If FHCRC is set, a CRC16 for the gzip header is present,
immediately before the compressed data. The CRC16 consists
of the two least significant bytes of the CRC32 for all
bytes of the gzip header up to and not including the CRC16.
[The FHCRC bit was never set by versions of gzip up to
1.2.4, even though it was documented with a different
meaning in gzip 1.2.4.]
If FEXTRA is set, optional extra fields are present, as
described in a following section.
Deutsch Informational [Page 6]
RFC 1952 GZIP File Format Specification May 1996
If FNAME is set, an original file name is present,
terminated by a zero byte. The name must consist of ISO
8859-1 (LATIN-1) characters; on operating systems using
EBCDIC or any other character set for file names, the name
must be translated to the ISO LATIN-1 character set. This
is the original name of the file being compressed, with any
directory components removed, and, if the file being
compressed is on a file system with case insensitive names,
forced to lower case. There is no original file name if the
data was compressed from a source other than a named file;
for example, if the source was stdin on a Unix system, there
is no file name.
If FCOMMENT is set, a zero-terminated file comment is
present. This comment is not interpreted; it is only
intended for human consumption. The comment must consist of
ISO 8859-1 (LATIN-1) characters. Line breaks should be
denoted by a single line feed character (10 decimal).
Reserved FLG bits must be zero.
MTIME (Modification TIME)
This gives the most recent modification time of the original
file being compressed. The time is in Unix format, i.e.,
seconds since 00:00:00 GMT, Jan. 1, 1970. (Note that this
may cause problems for MS-DOS and other systems that use
local rather than Universal time.) If the compressed data
did not come from a file, MTIME is set to the time at which
compression started. MTIME = 0 means no time stamp is
available.
XFL (eXtra FLags)
These flags are available for use by specific compression
methods. The "deflate" method (CM = 8) sets these flags as
follows:
XFL = 2 - compressor used maximum compression,
slowest algorithm
XFL = 4 - compressor used fastest algorithm
OS (Operating System)
This identifies the type of file system on which compression
took place. This may be useful in determining end-of-line
convention for text files. The currently defined values are
as follows:
Deutsch Informational [Page 7]
RFC 1952 GZIP File Format Specification May 1996
0 - FAT filesystem (MS-DOS, OS/2, NT/Win32)
1 - Amiga
2 - VMS (or OpenVMS)
3 - Unix
4 - VM/CMS
5 - Atari TOS
6 - HPFS filesystem (OS/2, NT)
7 - Macintosh
8 - Z-System
9 - CP/M
10 - TOPS-20
11 - NTFS filesystem (NT)
12 - QDOS
13 - Acorn RISCOS
255 - unknown
XLEN (eXtra LENgth)
If FLG.FEXTRA is set, this gives the length of the optional
extra field. See below for details.
CRC32 (CRC-32)
This contains a Cyclic Redundancy Check value of the
uncompressed data computed according to CRC-32 algorithm
used in the ISO 3309 standard and in section 8.1.1.6.2 of
ITU-T recommendation V.42. (See http://www.iso.ch for
ordering ISO documents. See gopher://info.itu.ch for an
online version of ITU-T V.42.)
ISIZE (Input SIZE)
This contains the size of the original (uncompressed) input
data modulo 2^32.
2.3.1.1. Extra field
If the FLG.FEXTRA bit is set, an "extra field" is present in
the header, with total length XLEN bytes. It consists of a
series of subfields, each of the form:
+---+---+---+---+==================================+
|SI1|SI2| LEN |... LEN bytes of subfield data ...|
+---+---+---+---+==================================+
SI1 and SI2 provide a subfield ID, typically two ASCII letters
with some mnemonic value. Jean-Loup Gailly
<gzip@prep.ai.mit.edu> is maintaining a registry of subfield
IDs; please send him any subfield ID you wish to use. Subfield
IDs with SI2 = 0 are reserved for future use. The following
IDs are currently defined:
Deutsch Informational [Page 8]
RFC 1952 GZIP File Format Specification May 1996
SI1 SI2 Data
---------- ---------- ----
0x41 ('A') 0x70 ('P') Apollo file type information
LEN gives the length of the subfield data, excluding the 4
initial bytes.
2.3.1.2. Compliance
A compliant compressor must produce files with correct ID1,
ID2, CM, CRC32, and ISIZE, but may set all the other fields in
the fixed-length part of the header to default values (255 for
OS, 0 for all others). The compressor must set all reserved
bits to zero.
A compliant decompressor must check ID1, ID2, and CM, and
provide an error indication if any of these have incorrect
values. It must examine FEXTRA/XLEN, FNAME, FCOMMENT and FHCRC
at least so it can skip over the optional fields if they are
present. It need not examine any other part of the header or
trailer; in particular, a decompressor may ignore FTEXT and OS
and always produce binary output, and still be compliant. A
compliant decompressor must give an error indication if any
reserved bit is non-zero, since such a bit could indicate the
presence of a new field that would cause subsequent data to be
interpreted incorrectly.

4. Security Considerations
Any data compression method involves the reduction of redundancy in
the data. Consequently, any corruption of the data is likely to have
severe effects and be difficult to correct. Uncompressed text, on
the other hand, will probably still be readable despite the presence
of some corrupted bytes.
It is recommended that systems using this data format provide some
means of validating the integrity of the compressed data, such as by
setting and checking the CRC-32 check value.

7. Appendix: Jean-Loup Gailly's gzip utility
The most widely used implementation of gzip compression, and the
original documentation on which this specification is based, were
created by Jean-Loup Gailly <gzip@prep.ai.mit.edu>. Since this
implementation is a de facto standard, we mention some more of its
features here. Again, the material in this section is not part of
the specification per se, and implementations need not follow it to
be compliant.
When compressing or decompressing a file, gzip preserves the
protection, ownership, and modification time attributes on the local
file system, since there is no provision for representing protection
attributes in the gzip file format itself. Since the file format
includes a modification time, the gzip decompressor provides a
command line switch that assigns the modification time from the file,
rather than the local modification time of the compressed input, to
the decompressed output.
8. Appendix: Sample CRC Code
The following sample code represents a practical implementation of
the CRC (Cyclic Redundancy Check). (See also ISO 3309 and ITU-T V.42
for a formal specification.)
The sample code is in the ANSI C programming language. Non C users
may find it easier to read with these hints:
& Bitwise AND operator.
^ Bitwise exclusive-OR operator.
>> Bitwise right shift operator. When applied to an
unsigned quantity, as here, right shift inserts zero
bit(s) at the left.
! Logical NOT operator.
++ "n++" increments the variable n.
0xNNN 0x introduces a hexadecimal (base 16) constant.
Suffix L indicates a long value (at least 32 bits).

A Fast Method for Identifying Plain Text Files
==============================================
Introduction
------------
Given a file coming from an unknown source, it is sometimes desirable
to find out whether the format of that file is plain text. Although
this may appear like a simple task, a fully accurate detection of the
file type requires heavy-duty semantic analysis on the file contents.
It is, however, possible to obtain satisfactory results by employing
various heuristics.
Previous versions of PKZip and other zip-compatible compression tools
were using a crude detection scheme: if more than 80% (4/5) of the bytes
found in a certain buffer are within the range [7..127], the file is
labeled as plain text, otherwise it is labeled as binary. A prominent
limitation of this scheme is the restriction to Latin-based alphabets.
Other alphabets, like Greek, Cyrillic or Asian, make extensive use of
the bytes within the range [128..255], and texts using these alphabets
are most often misidentified by this scheme; in other words, the rate
of false negatives is sometimes too high, which means that the recall
is low. Another weakness of this scheme is a reduced precision, due to
the false positives that may occur when binary files containing large
amounts of textual characters are misidentified as plain text.
In this article we propose a new, simple detection scheme that features
a much increased precision and a near-100% recall. This scheme is
designed to work on ASCII, Unicode and other ASCII-derived alphabets,
and it handles single-byte encodings (ISO-8859, MacRoman, KOI8, etc.)
and variable-sized encodings (ISO-2022, UTF-8, etc.). Wider encodings
(UCS-2/UTF-16 and UCS-4/UTF-32) are not handled, however.
The Algorithm
-------------
The algorithm works by dividing the set of bytecodes [0..255] into three
categories:
- The white list of textual bytecodes:
9 (TAB), 10 (LF), 13 (CR), 32 (SPACE) to 255.
- The gray list of tolerated bytecodes:
7 (BEL), 8 (BS), 11 (VT), 12 (FF), 26 (SUB), 27 (ESC).
- The black list of undesired, non-textual bytecodes:
0 (NUL) to 6, 14 to 31.
If a file contains at least one byte that belongs to the white list and
no byte that belongs to the black list, then the file is categorized as
plain text; otherwise, it is categorized as binary. (The boundary case,
when the file is empty, automatically falls into the latter category.)
Rationale
---------
The idea behind this algorithm relies on two observations.
The first observation is that, although the full range of 7-bit codes
[0..127] is properly specified by the ASCII standard, most control
characters in the range [0..31] are not used in practice. The only
widely-used, almost universally-portable control codes are 9 (TAB),
10 (LF) and 13 (CR). There are a few more control codes that are
recognized on a reduced range of platforms and text viewers/editors:
7 (BEL), 8 (BS), 11 (VT), 12 (FF), 26 (SUB) and 27 (ESC); but these
codes are rarely (if ever) used alone, without being accompanied by
some printable text. Even the newer, portable text formats such as
XML avoid using control characters outside the list mentioned here.
The second observation is that most of the binary files tend to contain
control characters, especially 0 (NUL). Even though the older text
detection schemes observe the presence of non-ASCII codes from the range
[128..255], the precision rarely has to suffer if this upper range is
labeled as textual, because the files that are genuinely binary tend to
contain both control characters and codes from the upper range. On the
other hand, the upper range needs to be labeled as textual, because it
is used by virtually all ASCII extensions. In particular, this range is
used for encoding non-Latin scripts.
Since there is no counting involved, other than simply observing the
presence or the absence of some byte values, the algorithm produces
consistent results, regardless what alphabet encoding is being used.
(If counting were involved, it could be possible to obtain different
results on a text encoded, say, using ISO-8859-16 versus UTF-8.)
There is an extra category of plain text files that are "polluted" with
one or more black-listed codes, either by mistake or by peculiar design
considerations. In such cases, a scheme that tolerates a small fraction
of black-listed codes would provide an increased recall (i.e. more true
positives). This, however, incurs a reduced precision overall, since
false positives are more likely to appear in binary files that contain
large chunks of textual data. Furthermore, "polluted" plain text should
be regarded as binary by general-purpose text detection schemes, because
general-purpose text processing algorithms might not be applicable.
Under this premise, it is safe to say that our detection method provides
a near-100% recall.
Experiments have been run on many files coming from various platforms
and applications. We tried plain text files, system logs, source code,
formatted office documents, compiled object code, etc. The results
confirm the optimistic assumptions about the capabilities of this
algorithm.

strm provides the memory allocation functions and window buffer on input,
and provides information on the unused input on return. For Z_DATA_ERROR
returns, strm will also provide an error message.
in() and out() are the call-back input and output functions. When
inflateBack() needs more input, it calls in(). When inflateBack() has
filled the window with output, or when it completes with data in the
window, it calls out() to write out the data. The application must not
change the provided input until in() is called again or inflateBack()
returns. The application must not change the window/output buffer until
inflateBack() returns.
in() and out() are called with a descriptor parameter provided in the
inflateBack() call. This parameter can be a structure that provides the
information required to do the read or write, as well as accumulated
information on the input and output such as totals and check values.
in() should return zero on failure. out() should return non-zero on
failure. If either in() or out() fails, than inflateBack() returns a
Z_BUF_ERROR. strm->next_in can be checked for Z_NULL to see whether it
was in() or out() that caused in the error. Otherwise, inflateBack()
returns Z_STREAM_END on success, Z_DATA_ERROR for an deflate format
error, or Z_MEM_ERROR if it could not allocate memory for the state.
inflateBack() can also return Z_STREAM_ERROR if the input parameters
are not correct, i.e. strm is Z_NULL or the state was not initialized.

Decompresses the source buffer into the destination buffer. *sourceLen is
the byte length of the source buffer. Upon entry, *destLen is the total size
of the destination buffer, which must be large enough to hold the entire
uncompressed data. (The size of the uncompressed data must have been saved
previously by the compressor and transmitted to the decompressor by some
mechanism outside the scope of this compression library.) Upon exit,
*destLen is the size of the decompressed data and *sourceLen is the number
of source bytes consumed. Upon return, source + *sourceLen points to the
first unused input byte.
uncompress returns Z_OK if success, Z_MEM_ERROR if there was not enough
memory, Z_BUF_ERROR if there was not enough room in the output buffer, or
Z_DATA_ERROR if the input data was corrupted, including if the input data is
an incomplete zlib stream.

.TH ZLIB 3 "15 Jan 2017"
.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, assuming that the standard library functions
used are thread safe, such as memory allocation routines.
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 may be added later
with the same stream interface.
.LP
Compression can be done in a single step if the buffers are large enough
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 the 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 test/example.c
and
.IR test/minigzip.c,
as well as other examples in the
.IR examples/
directory.
.LP
Changes to this version are documented in the file
.I ChangeLog
that accompanies the source.
.LP
.I zlib
is built in to many languages and operating systems, including but not limited to
Java, Python, .NET, PHP, Perl, Ruby, Swift, and Go.
.LP
An experimental package to read and write files in the .zip format,
written on top of
.I zlib
by Gilles Vollant (info@winimage.com),
is available at:
.IP
http://www.winimage.com/zLibDll/minizip.html
and also in the
.I contrib/minizip
directory of the main
.I zlib
source distribution.
.SH "SEE ALSO"
The
.I zlib
web site can be found at:
.IP
http://zlib.net/
.LP
The data format used by the
.I zlib
library is described by RFC
(Request for Comments) 1950 to 1952 in the files:
.IP
http://tools.ietf.org/html/rfc1950 (for the zlib header and trailer format)
.br
http://tools.ietf.org/html/rfc1951 (for the deflate compressed data format)
.br
http://tools.ietf.org/html/rfc1952 (for the gzip header and trailer format)
.LP
Mark Nelson wrote an article about
.I zlib
for the Jan. 1997 issue of Dr. Dobb's Journal;
a copy of the article is available at:
.IP
http://marknelson.us/1997/01/01/zlib-engine/
.SH "REPORTING PROBLEMS"
Before reporting a problem,
please check the
.I zlib
web site to verify that you have the latest version of
.IR zlib ;
otherwise,
obtain the latest version and see if the problem still exists.
Please read the
.I zlib
FAQ at:
.IP
http://zlib.net/zlib_faq.html
.LP
before asking for help.
Send questions and/or comments to zlib@gzip.org,
or (for the Windows DLL version) to Gilles Vollant (info@winimage.com).
