It does not aim for maximum -compression, or compatibility with any other compression library; instead, -it aims for very high speeds and reasonable compression. For instance, -compared to the fastest mode of zlib, Snappy is an order of magnitude faster -for most inputs, but the resulting compressed files are anywhere from 20% to -100% bigger. (For more information, see "Performance", below.) - -Snappy has the following properties: - - * Fast: Compression speeds at 250 MB/sec and beyond, with no assembler code. - See "Performance" below. - * Stable: Over the last few years, Snappy has compressed and decompressed - petabytes of data in Google's production environment. The Snappy bitstream - format is stable and will not change between versions. - * Robust: The Snappy decompressor is designed not to crash in the face of - corrupted or malicious input. - * Free and open source software: Snappy is licensed under a BSD-type license. - For more information, see the included COPYING file. - -Snappy has previously been called "Zippy" in some Google presentations -and the like. - - -Performance -=========== - -Snappy is intended to be fast. On a single core of a Core i7 processor -in 64-bit mode, it compresses at about 250 MB/sec or more and decompresses at -about 500 MB/sec or more. (These numbers are for the slowest inputs in our -benchmark suite; others are much faster.) In our tests, Snappy usually -is faster than algorithms in the same class (e.g. LZO, LZF, QuickLZ, -etc.) while achieving comparable compression ratios. - -Typical compression ratios (based on the benchmark suite) are about 1.5-1.7x -for plain text, about 2-4x for HTML, and of course 1.0x for JPEGs, PNGs and -other already-compressed data. Similar numbers for zlib in its fastest mode -are 2.6-2.8x, 3-7x and 1.0x, respectively. More sophisticated algorithms are -capable of achieving yet higher compression rates, although usually at the -expense of speed. Of course, compression ratio will vary significantly with -the input. - -Although Snappy should be fairly portable, it is primarily optimized -for 64-bit x86-compatible processors, and may run slower in other environments. -In particular: - - - Snappy uses 64-bit operations in several places to process more data at - once than would otherwise be possible. - - Snappy assumes unaligned 32 and 64-bit loads and stores are cheap. - On some platforms, these must be emulated with single-byte loads - and stores, which is much slower. - - Snappy assumes little-endian throughout, and needs to byte-swap data in - several places if running on a big-endian platform. - -Experience has shown that even heavily tuned code can be improved. -Performance optimizations, whether for 64-bit x86 or other platforms, -are of course most welcome; see "Contact", below. - - -Building -======== - -You need the CMake version specified in [CMakeLists.txt](./CMakeLists.txt) -or later to build: - -```bash -git submodule update --init -mkdir build -cd build && cmake ../ && make -``` - -Usage -===== - -Note that Snappy, both the implementation and the main interface, -is written in C++. However, several third-party bindings to other languages -are available; see the [home page](docs/README.md) for more information. -Also, if you want to use Snappy from C code, you can use the included C -bindings in snappy-c.h. - -To use Snappy from your own C++ program, include the file "snappy.h" from -your calling file, and link against the compiled library. - -There are many ways to call Snappy, but the simplest possible is - -```c++ -snappy::Compress(input.data(), input.size(), &output); -``` - -and similarly - -```c++ -snappy::Uncompress(input.data(), input.size(), &output); -``` - -where "input" and "output" are both instances of std::string. - -There are other interfaces that are more flexible in various ways, including -support for custom (non-array) input sources. See the header file for more -information. - - -Tests and benchmarks -==================== - -When you compile Snappy, the following binaries are compiled in addition to the -library itself. You do not need them to use the compressor from your own -library, but they are useful for Snappy development. - -* `snappy_benchmark` contains microbenchmarks used to tune compression and - decompression performance. -* `snappy_unittests` contains unit tests, verifying correctness on your machine - in various scenarios. -* `snappy_test_tool` can benchmark Snappy against a few other compression - libraries (zlib, LZO, LZF, and QuickLZ), if they were detected at configure - time. To benchmark using a given file, give the compression algorithm you want - to test Snappy against (e.g. --zlib) and then a list of one or more file names - on the command line. - -If you want to change or optimize Snappy, please run the tests and benchmarks to -verify you have not broken anything. - -The testdata/ directory contains the files used by the microbenchmarks, which -should provide a reasonably balanced starting point for benchmarking. (Note that -baddata[1-3].snappy are not intended as benchmarks; they are used to verify -correctness in the presence of corrupted data in the unit test.) - -Contributing to the Snappy Project -================================== - -In addition to the aims listed at the top of the [README](README.md) Snappy -explicitly supports the following: - -1. C++11 -2. Clang (gcc and MSVC are best-effort). -3. Low level optimizations (e.g. assembly or equivalent intrinsics) for: - - [x86](https://en.wikipedia.org/wiki/X86) - - [x86-64](https://en.wikipedia.org/wiki/X86-64) - - ARMv7 (32-bit) - - ARMv8 (AArch64) -4. Supports only the Snappy compression scheme as described in - [format_description.txt](format_description.txt). -5. CMake for building - -Changes adding features or dependencies outside of the core area of focus listed -above might not be accepted. If in doubt post a message to the -[Snappy discussion mailing list](https://groups.google.com/g/snappy-compression). - -We are unlikely to accept contributions to the build configuration files, such -as `CMakeLists.txt`. We are focused on maintaining a build configuration that -allows us to test that the project works in a few supported configurations -inside Google.

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.

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 , 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.

All the code is -thread safe. The data format used by the zlib library is described by RFCs -(Request for Comments) 1950 to 1952 in the files -http://tools.ietf.org/html/rfc1950 (zlib format), rfc1951 (deflate format) and -rfc1952 (gzip format). - -All functions of the compression library are documented in the file zlib.h -(volunteer to write man pages welcome, contact zlib@gzip.org). A usage example -of the library is given in the file test/example.c which also tests that -the library is working correctly. Another example is given in the file -test/minigzip.c. The compression library itself is composed of all source -files in the root directory. - -To compile all files and run the test program, follow the instructions given at -the top of Makefile.in. In short "./configure; make test", and if that goes -well, "make install" should work for most flavors of Unix. For Windows, use -one of the special makefiles in win32/ or contrib/vstudio/ . For VMS, use -make_vms.com. - -Questions about zlib should be sent to , or to Gilles Vollant - for the Windows DLL version. The zlib home page is -http://zlib.net/ . Before reporting a problem, please check this site to -verify that you have the latest version of zlib; otherwise get the latest -version and check whether the problem still exists or not. - -PLEASE read the zlib FAQ http://zlib.net/zlib_faq.html before asking for help. - -Mark Nelson wrote an article about zlib for the Jan. 1997 -issue of Dr. Dobb's Journal; a copy of the article is available at -http://marknelson.us/1997/01/01/zlib-engine/ . - -The changes made in version 1.2.13 are documented in the file ChangeLog. - -Unsupported third party contributions are provided in directory contrib/ . - -zlib is available in Java using the java.util.zip package, documented at -http://java.sun.com/developer/technicalArticles/Programming/compression/ . - -A Perl interface to zlib written by Paul Marquess is available -at CPAN (Comprehensive Perl Archive Network) sites, including -http://search.cpan.org/~pmqs/IO-Compress-Zlib/ . - -A Python interface to zlib written by A.M. Kuchling is -available in Python 1.5 and later versions, see -http://docs.python.org/library/zlib.html . - -zlib is built into tcl: http://wiki.tcl.tk/4610 . - -An experimental package to read and write files in .zip format, written on top -of zlib by Gilles Vollant , is available in the -contrib/minizip directory of zlib. - - -Notes for some targets: - -- For Windows DLL versions, please see win32/DLL_FAQ.txt - -- For 64-bit Irix, deflate.c must be compiled without any optimization. With - -O, one libpng test fails. The test works in 32 bit mode (with the -n32 - compiler flag). The compiler bug has been reported to SGI. - -- zlib doesn't work with gcc 2.6.3 on a DEC 3000/300LX under OSF/1 2.1 it works - when compiled with cc. - -- On Digital Unix 4.0D (formely OSF/1) on AlphaServer, the cc option -std1 is - necessary to get gzprintf working correctly. This is done by configure. - -- zlib doesn't work on HP-UX 9.05 with some versions of /bin/cc. It works with - other compilers. Use "make test" to check your compiler. - -- gzdopen is not supported on RISCOS or BEOS. - -- For PalmOs, see http://palmzlib.sourceforge.net/ - - -Acknowledgments: - - The deflate format used by zlib was defined by Phil Katz. The deflate and - zlib specifications were written by L. Peter Deutsch.

There are a series of bugs -and security problems associated with that old zlib version, and -we recommend the users to update their ZLib unit. - - -Summary of modifications -======================== - -- Improved makefile, adapted to zlib version 1.2.1. - -- Some field types from TZStreamRec are changed from Integer to - Longint, for consistency with the zlib.h header, and for 64-bit - readiness. - -- The zlib_version constant is updated. - -- The new Z_RLE strategy has its corresponding symbolic constant. - -- The allocation and deallocation functions and function types - (TAlloc, TFree, zlibAllocMem and zlibFreeMem) are now cdecl, - and _malloc and _free are added as C RTL stubs. As a result, - the original C sources of zlib can be compiled out of the box, - and linked to the ZLib unit. - - -Suggestions for improvements -============================ - -Currently, the ZLib unit provides only a limited wrapper around -the zlib library, and much of the original zlib functionality is -missing. Handling compressed file formats like ZIP/GZIP or PNG -cannot be implemented without having this functionality. -Applications that handle these formats are either using their own, -duplicated code, or not using the ZLib unit at all. - -Here are a few suggestions: - -- Checksum class wrappers around adler32() and crc32(), similar - to the Java classes that implement the java.util.zip.Checksum - interface. - -- The ability to read and write raw deflate streams, without the - zlib stream header and trailer. Raw deflate streams are used - in the ZIP file format. - -- The ability to read and write gzip streams, used in the GZIP - file format, and normally produced by the gzip program. - -- The ability to select a different compression strategy, useful - to PNG and MNG image compression, and to multimedia compression - in general. Besides the compression level - - TCompressionLevel = (clNone, clFastest, clDefault, clMax); - - which, in fact, could have used the 'z' prefix and avoided - TColor-like symbols - - TCompressionLevel = (zcNone, zcFastest, zcDefault, zcMax); -

It is meant to supplement RFC 1951, which formally -describes the deflate format. I have received many questions on details of the -deflate format, and I hope that reading this code will answer those questions. -puff.c is heavily commented with details of the deflate format, especially -those little nooks and cranies of the format that might not be obvious from a -specification. - -puff.c may also be useful in applications where code size or memory usage is a -very limited resource, and speed is not as important. - -How to use it -- - -Well, most likely you should just be reading puff.c and using zlib for actual -applications, but if you must ... - -Include puff.h in your code, which provides this prototype: - -int puff(unsigned char *dest, /* pointer to destination pointer */ - unsigned long *destlen, /* amount of output space */ - unsigned char *source, /* pointer to source data pointer */ - unsigned long *sourcelen); /* amount of input available */ - -Then you can call puff() to decompress a deflate stream that is in memory in -its entirety at source, to a sufficiently sized block of memory for the -decompressed data at dest. puff() is the only external symbol in puff.c The -only C library functions that puff.c needs are setjmp() and longjmp(), which -are used to simplify error checking in the code to improve readability. puff.c -does no memory allocation, and uses less than 2K bytes off of the stack. - -If destlen is not enough space for the uncompressed data, then inflate will -return an error without writing more than destlen bytes. Note that this means -that in order to decompress the deflate data successfully, you need to know -the size of the uncompressed data ahead of time. - -If needed, puff() can determine the size of the uncompressed data with no -output space. This is done by passing dest equal to (unsigned char *)0. Then -the initial value of *destlen is ignored and *destlen is set to the length of -the uncompressed data. So if the size of the uncompressed data is not known, -then two passes of puff() can be used--first to determine the size, and second -to do the actual inflation after allocating the appropriate memory. Not -pretty, but it works. (This is one of the reasons you should be using zlib.) - -The deflate format is self-terminating. If the deflate stream does not end -in *sourcelen bytes, puff() will return an error without reading at or past -endsource. - -On return, *sourcelen is updated to the amount of input data consumed, and -*destlen is updated to the size of the uncompressed data.

Unused symbols - * are common, hence the special coding for zero lengths. - * - * - The symbols for 0..18 are Huffman coded, and so that code must be - * described first. This is simply a sequence of up to 19 three-bit values - * representing no code (0) or the code length for that symbol (1..7). - * - * - A dynamic block starts with three fixed-size counts from which is computed - * the number of literal/length code lengths, the number of distance code - * lengths, and the number of code length code lengths (ok, you come up with - * a better name!) in the code descriptions. For the literal/length and - * distance codes, lengths after those provided are considered zero, i.e. no - * code.

* of the input text which are identical to earlier input (within a - * sliding window trailing behind the input currently being processed). - * - * The most straightforward technique turns out to be the fastest for - * most input files: try all possible matches and select the longest. - * The key feature of this algorithm is that insertions into the string - * dictionary are very simple and thus fast, and deletions are avoided - * completely. Insertions are performed at each input character, whereas - * string matches are performed only when the previous match ends. So it - * is preferable to spend more time in matches to allow very fast string - * insertions and avoid deletions. The matching algorithm for small - * strings is inspired from that of Rabin & Karp. A brute force approach - * is used to find longer strings when a small match has been found. - * A similar algorithm is used in comic (by Jan-Mark Wams) and freeze - * (by Leonid Broukhis). - * A previous version of this file used a more sophisticated algorithm - * (by Fiala and Greene) which is guaranteed to run in linear amortized - * time, but has a larger average cost, uses more memory and is patented. - * However the F&G algorithm may be faster for some highly redundant - * files if the parameter max_chain_length (described below) is too large. - * - * ACKNOWLEDGEMENTS - * - * The idea of lazy evaluation of matches is due to Jan-Mark Wams, and - * I found it in 'freeze' written by Leonid Broukhis. - * Thanks to many people for bug reports and testing. - * - * REFERENCES - * - * Deutsch, L.P.,"DEFLATE Compressed Data Format Specification". - * Available in http://tools.ietf.org/html/rfc1951 - * - * A description of the Rabin and Karp algorithm is given in the book - * "Algorithms" by R.

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.

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. - -3.

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] */ - - - - -Deutsch & Gailly Informational [Page 10] - -RFC 1950 ZLIB Compressed Data Format Specification May 1996 - - - unsigned long adler32(unsigned char *buf, int len) - { - return update_adler32(1L, buf, len); - } - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -Deutsch & Gailly Informational [Page 11] - diff --git a/cpp/third_party/zlib-1.2.13/doc/rfc1951.txt b/cpp/third_party/zlib-1.2.13/doc/rfc1951.txt deleted file mode 100644 index 403c8c722..000000000 --- a/cpp/third_party/zlib-1.2.13/doc/rfc1951.txt +++ /dev/null @@ -1,955 +0,0 @@ - - - - - - -Network Working Group P.

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 . 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. - - - - - - - - - - -Deutsch Informational [Page 4] - -RFC 1951 DEFLATE Compressed Data Format Specification May 1996 - - -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.

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).

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 - adds X,Y,X,Y,X to the output stream. - - We now specify each compression method in turn. - - 3.2.4.

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 - Code Bits Length(s) Code Bits Lengths Code Bits Length(s) - ---- ---- ------ ---- ---- ------- ---- ---- ------- - 257 0 3 267 1 15,16 277 4 67-82 - 258 0 4 268 1 17,18 278 4 83-98 - 259 0 5 269 2 19-22 279 4 99-114 - 260 0 6 270 2 23-26 280 4 115-130 - 261 0 7 271 2 27-30 281 5 131-162 - 262 0 8 272 2 31-34 282 5 163-194 - 263 0 9 273 3 35-42 283 5 195-226 - 264 0 10 274 3 43-50 284 5 227-257 - 265 1 11,12 275 3 51-58 285 0 258 - 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. - - Extra Extra Extra - Code Bits Dist Code Bits Dist Code Bits Distance - ---- ---- ---- ---- ---- ------ ---- ---- -------- - 0 0 1 10 4 33-48 20 9 1025-1536 - 1 0 2 11 4 49-64 21 9 1537-2048 - 2 0 3 12 5 65-96 22 10 2049-3072 - 3 0 4 13 5 97-128 23 10 3073-4096 - 4 1 5,6 14 6 129-192 24 11 4097-6144 - 5 1 7,8 15 6 193-256 25 11 6145-8192 - 6 2 9-12 16 7 257-384 26 12 8193-12288 - 7 2 13-16 17 7 385-512 27 12 12289-16384 - 8 3 17-24 18 8 513-768 28 13 16385-24576 - 9 3 25-32 19 8 769-1024 29 13 24577-32768 - - 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.

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. - - - - - -Deutsch Informational [Page 15] - -RFC 1951 DEFLATE Compressed Data Format Specification May 1996 - - -5.

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.

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.

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 allow 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 block 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 allow list and -no byte that belongs to the block 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 block-listed codes, either by mistake or by peculiar design -considerations. In such cases, a scheme that tolerates a small fraction -of block-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. - - --- -Cosmin Truta -Last updated: 2006-May-28 diff --git a/cpp/third_party/zlib-1.2.13/examples/README.examples b/cpp/third_party/zlib-1.2.13/examples/README.examples deleted file mode 100644 index e3a4b88bb..000000000 --- a/cpp/third_party/zlib-1.2.13/examples/README.examples +++ /dev/null @@ -1,54 +0,0 @@ -This directory contains examples of the use of zlib and other relevant -programs and documentation. - -enough.c - calculation and justification of ENOUGH parameter in inftrees.h - - calculates the maximum table space used in inflate tree - construction over all possible Huffman codes - -fitblk.c - compress just enough input to nearly fill a requested output size - - zlib isn't designed to do this, but fitblk does it anyway - -gun.c - uncompress a gzip file - - illustrates the use of inflateBack() for high speed file-to-file - decompression using call-back functions - - is approximately twice as fast as gzip -d - - also provides Unix uncompress functionality, again twice as fast - -gzappend.c - append to a gzip file - - illustrates the use of the Z_BLOCK flush parameter for inflate() - - illustrates the use of deflatePrime() to start at any bit - -gzjoin.c - join gzip files without recalculating the crc or recompressing - - illustrates the use of the Z_BLOCK flush parameter for inflate() - - illustrates the use of crc32_combine() - -gzlog.c -gzlog.h - efficiently and robustly maintain a message log file in gzip format - - illustrates use of raw deflate, Z_PARTIAL_FLUSH, deflatePrime(), - and deflateSetDictionary() - - illustrates use of a gzip header extra field - -gznorm.c - normalize a gzip file by combining members into a single member - - demonstrates how to concatenate deflate streams using Z_BLOCK - -zlib_how.html - painfully comprehensive description of zpipe.c (see below) - - describes in excruciating detail the use of deflate() and inflate() - -zpipe.c - reads and writes zlib streams from stdin to stdout - - illustrates the proper use of deflate() and inflate() - - deeply commented in zlib_how.html (see above) - -zran.c -zran.h - index a zlib or gzip stream and randomly access it - - illustrates the use of Z_BLOCK, inflatePrime(), and - inflateSetDictionary() to provide random access diff --git a/cpp/third_party/zlib-1.2.13/examples/enough.c b/cpp/third_party/zlib-1.2.13/examples/enough.c deleted file mode 100644 index 8a3cade49..000000000 --- a/cpp/third_party/zlib-1.2.13/examples/enough.c +++ /dev/null @@ -1,597 +0,0 @@ -/* enough.c -- determine the maximum size of inflate's Huffman code tables over - * all possible valid and complete prefix codes, subject to a length limit. - * Copyright (C) 2007, 2008, 2012, 2018 Mark Adler - * Version 1.5 5 August 2018 Mark Adler - */ - -/* Version history: - 1.0 3 Jan 2007 First version (derived from codecount.c version 1.4) - 1.1 4 Jan 2007 Use faster incremental table usage computation - Prune examine() search on previously visited states - 1.2 5 Jan 2007 Comments clean up - As inflate does, decrease root for short codes - Refuse cases where inflate would increase root - 1.3 17 Feb 2008 Add argument for initial root table size - Fix bug for initial root table size == max - 1 - Use a macro to compute the history index - 1.4 18 Aug 2012 Avoid shifts more than bits in type (caused endless loop!) - Clean up comparisons of different types - Clean up code indentation - 1.5 5 Aug 2018 Clean up code style, formatting, and comments - Show all the codes for the maximum, and only the maximum - */ - -/* - Examine all possible prefix codes for a given number of symbols and a - maximum code length in bits to determine the maximum table size for zlib's - inflate.

Those - properties are: we cannot use more bit patterns than are available; and when - all the symbols are used, there are exactly zero possible bit patterns left - unused. - - The inflate Huffman decoding algorithm uses two-level lookup tables for - speed. There is a single first-level table to decode codes up to root bits - in length (root == 9 for literal/length codes and root == 6 for distance - codes, in the current inflate implementation). The base table has 1 << root - entries and is indexed by the next root bits of input. Codes shorter than - root bits have replicated table entries, so that the correct entry is - pointed to regardless of the bits that follow the short code. If the code is - longer than root bits, then the table entry points to a second-level table. - The size of that table is determined by the longest code with that root-bit - prefix. If that longest code has length len, then the table has size 1 << - (len - root), to index the remaining bits in that set of codes. Each - subsequent root-bit prefix then has its own sub-table. The total number of - table entries required by the code is calculated incrementally as the number - of codes at each bit length is populated. When all of the codes are shorter - than root bits, then root is reduced to the longest code length, resulting - in a single, smaller, one-level table. - - The inflate algorithm also provides for small values of root (relative to - the log2 of the number of symbols), where the shortest code has more bits - than root. In that case, root is increased to the length of the shortest - code. This program, by design, does not handle that case, so it is verified - that the number of symbols is less than 1 << (root + 1). - - In order to speed up the examination (by about ten orders of magnitude for - the default arguments), the intermediate states in the build-up of a code - are remembered and previously visited branches are pruned. The memory - required for this will increase rapidly with the total number of symbols and - the maximum code length in bits. However this is a very small price to pay - for the vast speedup. - - First, all of the possible prefix codes are counted, and reachable - intermediate states are noted by a non-zero count in a saved-results array. - Second, the intermediate states that lead to (root + 1) bit or longer codes - are used to look at all sub-codes from those junctures for their inflate - memory usage. (The amount of memory used is not affected by the number of - codes of root bits or less in length.) Third, the visited states in the - construction of those sub-codes and the associated calculation of the table - size is recalled in order to avoid recalculating from the same juncture. - Beginning the code examination at (root + 1) bit codes, which is enabled by - identifying the reachable nodes, accounts for about six of the orders of - magnitude of improvement for the default arguments. About another four - orders of magnitude come from not revisiting previous states.

The gzip file is written to directly, to - avoid copying that file, in case it's large. Note that this results in the - unfriendly behavior that if gzappend fails, the gzip file is corrupted. - - This program was written to illustrate the use of the new Z_BLOCK option of - zlib 1.2.x's inflate() function. This option returns from inflate() at each - block boundary to facilitate locating and modifying the last block bit at - the start of the final deflate block. Also whether using Z_BLOCK or not, - another required feature of zlib 1.2.x is that inflate() now provides the - number of unused bits in the last input byte used. gzappend will not work - with versions of zlib earlier than 1.2.1. - - gzappend first decompresses the gzip file internally, discarding all but - the last 32K of uncompressed data, and noting the location of the last block - bit and the number of unused bits in the last byte of the compressed data. - The gzip trailer containing the CRC-32 and length of the uncompressed data - is verified. This trailer will be later overwritten. - - Then the last block bit is cleared by seeking back in the file and rewriting - the byte that contains it. Seeking forward, the last byte of the compressed - data is saved along with the number of unused bits to initialize deflate. - - A deflate process is initialized, using the last 32K of the uncompressed - data from the gzip file to initialize the dictionary. If the total - uncompressed data was less than 32K, then all of it is used to initialize - the dictionary. The deflate output bit buffer is also initialized with the - last bits from the original deflate stream. From here on, the data to - append is simply compressed using deflate, and written to the gzip file. - When that is complete, the new CRC-32 and uncompressed length are written - as the trailer of the gzip file. - */ - -#include -#include -#include -#include -#include -#include "zlib.h" - -#define local static -#define LGCHUNK 14 -#define CHUNK (1U << LGCHUNK) -#define DSIZE 32768U - -/* print an error message and terminate with extreme prejudice */ -local void bye(char *msg1, char *msg2) -{ - fprintf(stderr, "gzappend error: %s%s\n", msg1, msg2);

This minimizes the impact to the compression ratio of appending. - */ - -/* - Operations Concept: - - Files (log name "foo"): - foo.gz -- gzip file with the complete log - foo.add -- last message to append or last data to compress - foo.dict -- dictionary of the last 32K of data for next compression - foo.temp -- temporary dictionary file for compression after this one - foo.lock -- lock file for reading and writing the other files - foo.repairs -- log file for log file recovery operations (not compressed) - - gzip file structure: - - fixed-length (no file name) header with extra field (see below) - - compressed data ending initially with empty stored block - - uncompressed data filling out originally empty stored block and - subsequent stored blocks as needed (16K max each) - - gzip trailer - - no junk at end (no other gzip streams) - - When appending data, the information in the first three items above plus the - foo.add file are sufficient to recover an interrupted append operation. The - extra field has the necessary information to restore the start of the last - stored block and determine where to append the data in the foo.add file, as - well as the crc and length of the gzip data before the append operation. - - The foo.add file is created before the gzip file is marked for append, and - deleted after the gzip file is marked as complete. So if the append - operation is interrupted, the data to add will still be there. If due to - some external force, the foo.add file gets deleted between when the append - operation was interrupted and when recovery is attempted, the gzip file will - still be restored, but without the appended data. - - When compressing data, the information in the first two items above plus the - foo.add file are sufficient to recover an interrupted compress operation. - The extra field has the necessary information to find the end of the - compressed data, and contains both the crc and length of just the compressed - data and of the complete set of data including the contents of the foo.add - file. - - Again, the foo.add file is maintained during the compress operation in case - of an interruption. If in the unlikely event the foo.add file with the data - to be compressed is missing due to some external force, a gzip file with - just the previous compressed data will be reconstructed. In this case, all - of the data that was to be compressed is lost (approximately one megabyte). - This will not occur if all that happened was an interruption of the compress - operation. - - The third state that is marked is the replacement of the old dictionary with - the new dictionary after a compress operation. Once compression is - complete, the gzip file is marked as being in the replace state. This - completes the gzip file, so an interrupt after being so marked does not - result in recompression. Then the dictionary file is replaced, and the gzip - file is marked as completed. This state prevents the possibility of - restarting compression with the wrong dictionary file. - - All three operations are wrapped by a lock/unlock procedure. In order to - gain exclusive access to the log files, first a foo.lock file must be - exclusively created. When all operations are complete, the lock is - released by deleting the foo.lock file. If when attempting to create the - lock file, it already exists and the modify time of the lock file is more - than five minutes old (set by the PATIENCE define below), then the old - lock file is considered stale and deleted, and the exclusive creation of - the lock file is retried. To assure that there are no false assessments - of the staleness of the lock file, the operations periodically touch the - lock file to update the modified date. - - Following is the definition of the extra field with all of the information - required to enable the above append and compress operations and their - recovery if interrupted. Multi-byte values are stored little endian - (consistent with the gzip format). File pointers are eight bytes long. - The crc's and lengths for the gzip trailer are four bytes long. (Note that - the length at the end of a gzip file is used for error checking only, and - for large files is actually the length modulo 2^32.) The stored block - length is two bytes long. The gzip extra field two-byte identification is - "ap" for append. It is assumed that writing the extra field to the file is - an "atomic" operation. That is, either all of the extra field is written - to the file, or none of it is, if the operation is interrupted right at the - point of updating the extra field. This is a reasonable assumption, since - the extra field is within the first 52 bytes of the file, which is smaller - than any expected block size for a mass storage device (usually 512 bytes or - larger). - - Extra field (35 bytes): - - Pointer to first stored block length -- this points to the two-byte length - of the first stored block, which is followed by the two-byte, one's - complement of that length. The stored block length is preceded by the - three-bit header of the stored block, which is the actual start of the - stored block in the deflate format. See the bit offset field below. - - Pointer to the last stored block length. This is the same as above, but - for the last stored block of the uncompressed data in the gzip file. - Initially this is the same as the first stored block length pointer. - When the stored block gets to 16K (see the MAX_STORE define), then a new - stored block as added, at which point the last stored block length pointer - is different from the first stored block length pointer. When they are - different, the first bit of the last stored block header is eight bits, or - one byte back from the block length. - - Compressed data crc and length. This is the crc and length of the data - that is in the compressed portion of the deflate stream. These are used - only in the event that the foo.add file containing the data to compress is - lost after a compress operation is interrupted. - - Total data crc and length. This is the crc and length of all of the data - stored in the gzip file, compressed and uncompressed. It is used to - reconstruct the gzip trailer when compressing, as well as when recovering - interrupted operations. - - Final stored block length. This is used to quickly find where to append, - and allows the restoration of the original final stored block state when - an append operation is interrupted. - - First stored block start as the number of bits back from the final stored - block first length byte. This value is in the range of 3..10, and is - stored as the low three bits of the final byte of the extra field after - subtracting three (0..7). This allows the last-block bit of the stored - block header to be updated when a new stored block is added, for the case - when the first stored block and the last stored block are the same. (When - they are different, the numbers of bits back is known to be eight.) This - also allows for new compressed data to be appended to the old compressed - data in the compress operation, overwriting the previous first stored - block, or for the compressed data to be terminated and a valid gzip file - reconstructed on the off chance that a compression operation was - interrupted and the data to compress in the foo.add file was deleted. - - The operation in process. This is the next two bits in the last byte (the - bits under the mask 0x18). The are interpreted as 0: nothing in process, - 1: append in process, 2: compress in process, 3: replace in process. - - The top three bits of the last byte in the extra field are reserved and - are currently set to zero. - - Main procedure: - - Exclusively create the foo.lock file using the O_CREAT and O_EXCL modes of - the system open() call. If the modify time of an existing lock file is - more than PATIENCE seconds old, then the lock file is deleted and the - exclusive create is retried. - - Load the extra field from the foo.gz file, and see if an operation was in - progress but not completed. If so, apply the recovery procedure below. - - Perform the append procedure with the provided data. - - If the uncompressed data in the foo.gz file is 1MB or more, apply the - compress procedure. - - Delete the foo.lock file. - - Append procedure: - - Put what to append in the foo.add file so that the operation can be - restarted if this procedure is interrupted. - - Mark the foo.gz extra field with the append operation in progress. - + Restore the original last-block bit and stored block length of the last - stored block from the information in the extra field, in case a previous - append operation was interrupted. - - Append the provided data to the last stored block, creating new stored - blocks as needed and updating the stored blocks last-block bits and - lengths. - - Update the crc and length with the new data, and write the gzip trailer. - - Write over the extra field (with a single write operation) with the new - pointers, lengths, and crc's, and mark the gzip file as not in process. - Though there is still a foo.add file, it will be ignored since nothing - is in process. If a foo.add file is leftover from a previously - completed operation, it is truncated when writing new data to it. - - Delete the foo.add file. - - Compress and replace procedures: - - Read all of the uncompressed data in the stored blocks in foo.gz and write - it to foo.add. Also write foo.temp with the last 32K of that data to - provide a dictionary for the next invocation of this procedure. - - Rewrite the extra field marking foo.gz with a compression in process. - * If there is no data provided to compress (due to a missing foo.add file - when recovering), reconstruct and truncate the foo.gz file to contain - only the previous compressed data and proceed to the step after the next - one. Otherwise ... - - Compress the data with the dictionary in foo.dict, and write to the - foo.gz file starting at the bit immediately following the last previously - compressed block. If there is no foo.dict, proceed anyway with the - compression at slightly reduced efficiency. (For the foo.dict file to be - missing requires some external failure beyond simply the interruption of - a compress operation.) During this process, the foo.lock file is - periodically touched to assure that that file is not considered stale by - another process before we're done. The deflation is terminated with a - non-last empty static block (10 bits long), that is then located and - written over by a last-bit-set empty stored block. - - Append the crc and length of the data in the gzip file (previously - calculated during the append operations). - - Write over the extra field with the updated stored block offsets, bits - back, crc's, and lengths, and mark foo.gz as in process for a replacement - of the dictionary. - @ Delete the foo.add file. - - Replace foo.dict with foo.temp. - - Write over the extra field, marking foo.gz as complete. - - Recovery procedure: - - If not a replace recovery, read in the foo.add file, and provide that data - to the appropriate recovery below. If there is no foo.add file, provide - a zero data length to the recovery. In that case, the append recovery - restores the foo.gz to the previous compressed + uncompressed data state. - For the the compress recovery, a missing foo.add file results in foo.gz - being restored to the previous compressed-only data state. - - Append recovery: - - Pick up append at + step above - - Compress recovery: - - Pick up compress at * step above - - Replace recovery: - - Pick up compress at @ step above - - Log the repair with a date stamp in foo.repairs - */ - -#include -#include /* rename, fopen, fprintf, fclose */ -#include /* malloc, free */ -#include /* strlen, strrchr, strcpy, strncpy, strcmp */ -#include /* open */ -#include /* lseek, read, write, close, unlink, sleep, */ - /* ftruncate, fsync */ -#include /* errno */ -#include /* time, ctime */ -#include /* stat */ -#include /* utimes */ -#include "zlib.h" /* crc32 */ - -#include "gzlog.h" /* header for external access */ - -#define local static -typedef unsigned int uint; -typedef unsigned long ulong; - -/* Macro for debugging to deterministically force recovery operations */ -#ifdef GZLOG_DEBUG - #include /* longjmp */ - jmp_buf gzlog_jump; /* where to go back to */ - int gzlog_bail = 0; /* which point to bail at (1..8) */ - int gzlog_count = -1; /* number of times through to wait */ -# define BAIL(n) do { if (n == gzlog_bail && gzlog_count-- == 0) \ - longjmp(gzlog_jump, gzlog_bail); } while (0) -#else -# define BAIL(n) -#endif - -/* how old the lock file can be in seconds before considering it stale */ -#define PATIENCE 300 - -/* maximum stored block size in Kbytes -- must be in 1..63 */ -#define MAX_STORE 16 - -/* number of stored Kbytes to trigger compression (must be >= 32 to allow - dictionary construction, and <= 204 * MAX_STORE, in order for >> 10 to - discard the stored block headers contribution of five bytes each) */ -#define TRIGGER 1024 - -/* size of a deflate dictionary (this cannot be changed) */ -#define DICT 32768U - -/* values for the operation (2 bits) */ -#define NO_OP 0 -#define APPEND_OP 1 -#define COMPRESS_OP 2 -#define REPLACE_OP 3 - -/* macros to extract little-endian integers from an unsigned byte buffer */ -#define PULL2(p) ((p)[0]+((uint)((p)[1])<<8)) -#define PULL4(p) (PULL2(p)+((ulong)PULL2(p+2)<<16)) -#define PULL8(p) (PULL4(p)+((off_t)PULL4(p+4)<<32)) - -/* macros to store integers into a byte buffer in little-endian order */ -#define PUT2(p,a) do {(p)[0]=a;(p)[1]=(a)>>8;} while(0) -#define PUT4(p,a) do {PUT2(p,a);PUT2(p+2,a>>16);} while(0) -#define PUT8(p,a) do {PUT4(p,a);PUT4(p+4,a>>32);} while(0) - -/* internal structure for log information */ -#define LOGID "\106\035\172" /* should be three non-zero characters */ -struct log { - char id[4]; /* contains LOGID to detect inadvertent overwrites */ - int fd; /* file descriptor for .gz file, opened read/write */ - char *path; /* allocated path, e.g. "/var/log/foo" or "foo" */ - char *end; /* end of path, for appending suffices such as ".gz" */ - off_t first; /* offset of first stored block first length byte */ - int back; /* location of first block id in bits back from first */ - uint stored; /* bytes currently in last stored block */ - off_t last; /* offset of last stored block first length byte */ - ulong ccrc; /* crc of compressed data */ - ulong clen; /* length (modulo 2^32) of compressed data */ - ulong tcrc; /* crc of total data */ - ulong tlen; /* length (modulo 2^32) of total data */ - time_t lock; /* last modify time of our lock file */ -}; - -/* gzip header for gzlog */ -local unsigned char log_gzhead[] = { - 0x1f, 0x8b, /* magic gzip id */ - 8, /* compression method is deflate */ - 4, /* there is an extra field (no file name) */ - 0, 0, 0, 0, /* no modification time provided */ - 0, 0xff, /* no extra flags, no OS specified */ - 39, 0, 'a', 'p', 35, 0 /* extra field with "ap" subfield */ - /* 35 is EXTRA, 39 is EXTRA + 4 */ -}; - -#define HEAD sizeof(log_gzhead) /* should be 16 */ - -/* initial gzip extra field content (52 == HEAD + EXTRA + 1) */ -local unsigned char log_gzext[] = { - 52, 0, 0, 0, 0, 0, 0, 0, /* offset of first stored block length */ - 52, 0, 0, 0, 0, 0, 0, 0, /* offset of last stored block length */ - 0, 0, 0, 0, 0, 0, 0, 0, /* compressed data crc and length */ - 0, 0, 0, 0, 0, 0, 0, 0, /* total data crc and length */ - 0, 0, /* final stored block data length */ - 5 /* op is NO_OP, last bit 8 bits back */ -}; - -#define EXTRA sizeof(log_gzext) /* should be 35 */ - -/* initial gzip data and trailer */ -local unsigned char log_gzbody[] = { - 1, 0, 0, 0xff, 0xff, /* empty stored block (last) */ - 0, 0, 0, 0, /* crc */ - 0, 0, 0, 0 /* uncompressed length */ -}; - -#define BODY sizeof(log_gzbody) - -/* Exclusively create foo.lock in order to negotiate exclusive access to the - foo.* files.

zlib Usage Example

-We often get questions about how the deflate() and inflate() functions should be used. -Users wonder when they should provide more input, when they should use more output, -what to do with a Z_BUF_ERROR, how to make sure the process terminates properly, and -so on. So for those who have read zlib.h (a few times), and -would like further edification, below is an annotated example in C of simple routines to compress and decompress -from an input file to an output file using deflate() and inflate() respectively. The -annotations are interspersed between lines of the code. So please read between the lines. -We hope this helps explain some of the intricacies of zlib. -

-Without further adieu, here is the program zpipe.c: -

-We now include the header files for the required definitions. From -stdio.h we use fopen(), fread(), fwrite(), -feof(), ferror(), and fclose() for file i/o, and -fputs() for error messages. From string.h we use -strcmp() for command line argument processing. -From assert.h we use the assert() macro. -From zlib.h -we use the basic compression functions deflateInit(), -deflate(), and deflateEnd(), and the basic decompression -functions inflateInit(), inflate(), and -inflateEnd(). -

-#include <stdio.h>
-#include <string.h>
-#include <assert.h>
-#include "zlib.h"
-
-This is an ugly hack required to avoid corruption of the input and output data on -Windows/MS-DOS systems. Without this, those systems would assume that the input and output -files are text, and try to convert the end-of-line characters from one standard to -another. That would corrupt binary data, and in particular would render the compressed data unusable. -This sets the input and output to binary which suppresses the end-of-line conversions. -SET_BINARY_MODE() will be used later on stdin and stdout, at the beginning of main(). -

-#  define SET_BINARY_MODE(file)

-
-CHUNK is simply the buffer size for feeding data to and pulling data -from the zlib routines. Larger buffer sizes would be more efficient, -especially for inflate(). If the memory is available, buffers sizes -on the order of 128K or 256K bytes should be used. -

-#define CHUNK 16384
-
-The def() routine compresses data from an input file to an output file. The output data -will be in the zlib format, which is different from the gzip or zip -formats. The zlib format has a very small header of only two bytes to identify it as -a zlib stream and to provide decoding information, and a four-byte trailer with a fast -check value to verify the integrity of the uncompressed data after decoding. -

-/* Compress from file source to file dest until EOF on source.
-   def() returns Z_OK on success, Z_MEM_ERROR if memory could not be
-   allocated for processing, Z_STREAM_ERROR if an invalid compression
-   level is supplied, Z_VERSION_ERROR if the version of zlib.h and the
-   version of the library linked do not match, or Z_ERRNO if there is
-   an error reading or writing the files. */
-int def(FILE *source, FILE *dest, int level)
-{
-
-Here are the local variables for def(). ret will be used for zlib -return codes. flush will keep track of the current flushing state for deflate(), -which is either no flushing, or flush to completion after the end of the input file is reached. -have is the amount of data returned from deflate(). The strm structure -is used to pass information to and from the zlib routines, and to maintain the -deflate() state. in and out are the input and output buffers for -deflate(). -

-    int ret, flush;
-    unsigned have;
-    z_stream strm;
-    unsigned char in[CHUNK];
-    unsigned char out[CHUNK];
-
-The first thing we do is to initialize the zlib state for compression using -deflateInit(). This must be done before the first use of deflate(). -The zalloc, zfree, and opaque fields in the strm -structure must be initialized before calling deflateInit(). Here they are -set to the zlib constant Z_NULL to request that zlib use -the default memory allocation routines. An application may also choose to provide -custom memory allocation routines here. deflateInit() will allocate on the -order of 256K bytes for the internal state. -(See zlib Technical Details.) -

-deflateInit() is called with a pointer to the structure to be initialized and -the compression level, which is an integer in the range of -1 to 9. Lower compression -levels result in faster execution, but less compression. Higher levels result in -greater compression, but slower execution. The zlib constant Z_DEFAULT_COMPRESSION, -equal to -1, -provides a good compromise between compression and speed and is equivalent to level 6. -Level 0 actually does no compression at all, and in fact expands the data slightly to produce -the zlib format (it is not a byte-for-byte copy of the input). -More advanced applications of zlib -may use deflateInit2() here instead. Such an application may want to reduce how -much memory will be used, at some price in compression. Or it may need to request a -gzip header and trailer instead of a zlib header and trailer, or raw -encoding with no header or trailer at all. -

-We must check the return value of deflateInit() against the zlib constant -Z_OK to make sure that it was able to -allocate memory for the internal state, and that the provided arguments were valid. -deflateInit() will also check that the version of zlib that the zlib.h -file came from matches the version of zlib actually linked with the program. This -is especially important for environments in which zlib is a shared library. -

-Note that an application can initialize multiple, independent zlib streams, which can -operate in parallel. The state information maintained in the structure allows the zlib -routines to be reentrant. -


-    /* allocate deflate state */
-    strm.zalloc = Z_NULL;
-    strm.zfree = Z_NULL;
-    strm.opaque = Z_NULL;
-    ret = deflateInit(&strm, level);
-    if (ret != Z_OK)
-        return ret;
-
-With the pleasantries out of the way, now we can get down to business. The outer do-loop -reads all of the input file and exits at the bottom of the loop once end-of-file is reached. -This loop contains the only call of deflate(). So we must make sure that all of the -input data has been processed and that all of the output data has been generated and consumed -before we fall out of the loop at the bottom. -

-    /* compress until end of file */
-    do {
-
-We start off by reading data from the input file. The number of bytes read is put directly -into avail_in, and a pointer to those bytes is put into next_in. We also -check to see if end-of-file on the input has been reached. If we are at the end of file, then flush is set to the -zlib constant Z_FINISH, which is later passed to deflate() to -indicate that this is the last chunk of input data to compress. We need to use feof() -to check for end-of-file as opposed to seeing if fewer than CHUNK bytes have been read. The -reason is that if the input file length is an exact multiple of CHUNK, we will miss -the fact that we got to the end-of-file, and not know to tell deflate() to finish -up the compressed stream. If we are not yet at the end of the input, then the zlib -constant Z_NO_FLUSH will be passed to deflate to indicate that we are still -in the middle of the uncompressed data. -

-If there is an error in reading from the input file, the process is aborted with -deflateEnd() being called to free the allocated zlib state before returning -the error. We wouldn't want a memory leak, now would we? deflateEnd() can be called -at any time after the state has been initialized. Once that's done, deflateInit() (or -deflateInit2()) would have to be called to start a new compression process. There is -no point here in checking the deflateEnd() return code. The deallocation can't fail. -


-        strm.avail_in = fread(in, 1, CHUNK, source);
-        if (ferror(source)) {
-            (void)deflateEnd(&strm);
-            return Z_ERRNO;
-        }
-        flush = feof(source) ? Z_FINISH : Z_NO_FLUSH;
-        strm.next_in = in;
-
-The inner do-loop passes our chunk of input data to deflate(), and then -keeps calling deflate() until it is done producing output. Once there is no more -new output, deflate() is guaranteed to have consumed all of the input, i.e., -avail_in will be zero. -

-        /* run deflate() on input until output buffer not full, finish
-           compression if all of source has been read in */
-        do {
-
-Output space is provided to deflate() by setting avail_out to the number -of available output bytes and next_out to a pointer to that space. -

-            strm.avail_out = CHUNK;
-            strm.next_out = out;
-
-Now we call the compression engine itself, deflate(). It takes as many of the -avail_in bytes at next_in as it can process, and writes as many as -avail_out bytes to next_out. Those counters and pointers are then -updated past the input data consumed and the output data written. It is the amount of -output space available that may limit how much input is consumed. -Hence the inner loop to make sure that -all of the input is consumed by providing more output space each time. Since avail_in -and next_in are updated by deflate(), we don't have to mess with those -between deflate() calls until it's all used up. -

-The parameters to deflate() are a pointer to the strm structure containing -the input and output information and the internal compression engine state, and a parameter -indicating whether and how to flush data to the output. Normally deflate will consume -several K bytes of input data before producing any output (except for the header), in order -to accumulate statistics on the data for optimum compression. It will then put out a burst of -compressed data, and proceed to consume more input before the next burst. Eventually, -deflate() -must be told to terminate the stream, complete the compression with provided input data, and -write out the trailer check value. deflate() will continue to compress normally as long -as the flush parameter is Z_NO_FLUSH. Once the Z_FINISH parameter is provided, -deflate() will begin to complete the compressed output stream. However depending on how -much output space is provided, deflate() may have to be called several times until it -has provided the complete compressed stream, even after it has consumed all of the input. The flush -parameter must continue to be Z_FINISH for those subsequent calls. -

-There are other values of the flush parameter that are used in more advanced applications. You can -force deflate() to produce a burst of output that encodes all of the input data provided -so far, even if it wouldn't have otherwise, for example to control data latency on a link with -compressed data. You can also ask that deflate() do that as well as erase any history up to -that point so that what follows can be decompressed independently, for example for random access -applications. Both requests will degrade compression by an amount depending on how often such -requests are made. -

-deflate() has a return value that can indicate errors, yet we do not check it here. Why -not? Well, it turns out that deflate() can do no wrong here. Let's go through -deflate()'s return values and dispense with them one by one. The possible values are -Z_OK, Z_STREAM_END, Z_STREAM_ERROR, or Z_BUF_ERROR. Z_OK -is, well, ok. Z_STREAM_END is also ok and will be returned for the last call of -deflate(). This is already guaranteed by calling deflate() with Z_FINISH -until it has no more output. Z_STREAM_ERROR is only possible if the stream is not -initialized properly, but we did initialize it properly. There is no harm in checking for -Z_STREAM_ERROR here, for example to check for the possibility that some -other part of the application inadvertently clobbered the memory containing the zlib state. -Z_BUF_ERROR will be explained further below, but -suffice it to say that this is simply an indication that deflate() could not consume -more input or produce more output. deflate() can be called again with more output space -or more available input, which it will be in this code. -


-            ret = deflate(&strm, flush);    /* no bad return value */
-            assert(ret != Z_STREAM_ERROR);  /* state not clobbered */
-
-Now we compute how much output deflate() provided on the last call, which is the -difference between how much space was provided before the call, and how much output space -is still available after the call. Then that data, if any, is written to the output file. -We can then reuse the output buffer for the next call of deflate(). Again if there -is a file i/o error, we call deflateEnd() before returning to avoid a memory leak. -

-            have = CHUNK - strm.avail_out;
-            if (fwrite(out, 1, have, dest) != have || ferror(dest)) {
-                (void)deflateEnd(&strm);
-                return Z_ERRNO;
-            }
-
-The inner do-loop is repeated until the last deflate() call fails to fill the -provided output buffer. Then we know that deflate() has done as much as it can with -the provided input, and that all of that input has been consumed. We can then fall out of this -loop and reuse the input buffer. -

-The way we tell that deflate() has no more output is by seeing that it did not fill -the output buffer, leaving avail_out greater than zero. However suppose that -deflate() has no more output, but just so happened to exactly fill the output buffer! -avail_out is zero, and we can't tell that deflate() has done all it can. -As far as we know, deflate() -has more output for us. So we call it again. But now deflate() produces no output -at all, and avail_out remains unchanged as CHUNK. That deflate() call -wasn't able to do anything, either consume input or produce output, and so it returns -Z_BUF_ERROR. (See, I told you I'd cover this later.) However this is not a problem at -all. Now we finally have the desired indication that deflate() is really done, -and so we drop out of the inner loop to provide more input to deflate(). -

-With flush set to Z_FINISH, this final set of deflate() calls will -complete the output stream. Once that is done, subsequent calls of deflate() would return -Z_STREAM_ERROR if the flush parameter is not Z_FINISH, and do no more processing -until the state is reinitialized. -

-Some applications of zlib have two loops that call deflate() -instead of the single inner loop we have here. The first loop would call -without flushing and feed all of the data to deflate(). The second loop would call -deflate() with no more -data and the Z_FINISH parameter to complete the process. As you can see from this -example, that can be avoided by simply keeping track of the current flush state. -


-        } while (strm.avail_out == 0);
-        assert(strm.avail_in == 0);     /* all input will be used */
-
-Now we check to see if we have already processed all of the input file. That information was -saved in the flush variable, so we see if that was set to Z_FINISH. If so, -then we're done and we fall out of the outer loop. We're guaranteed to get Z_STREAM_END -from the last deflate() call, since we ran it until the last chunk of input was -consumed and all of the output was generated. -

-        /* done when last data in file processed */
-    } while (flush != Z_FINISH);
-    assert(ret == Z_STREAM_END);        /* stream will be complete */
-
-The process is complete, but we still need to deallocate the state to avoid a memory leak -(or rather more like a memory hemorrhage if you didn't do this). Then -finally we can return with a happy return value. -

-    /* clean up and return */
-    (void)deflateEnd(&strm);
-    return Z_OK;
-}
-
-Now we do the same thing for decompression in the inf() routine. inf() -decompresses what is hopefully a valid zlib stream from the input file and writes the -uncompressed data to the output file. Much of the discussion above for def() -applies to inf() as well, so the discussion here will focus on the differences between -the two. -

-/* Decompress from file source to file dest until stream ends or EOF.
-   inf() returns Z_OK on success, Z_MEM_ERROR if memory could not be
-   allocated for processing, Z_DATA_ERROR if the deflate data is
-   invalid or incomplete, Z_VERSION_ERROR if the version of zlib.h and
-   the version of the library linked do not match, or Z_ERRNO if there
-   is an error reading or writing the files. */
-int inf(FILE *source, FILE *dest)
-{
-
-The local variables have the same functionality as they do for def(). The -only difference is that there is no flush variable, since inflate() -can tell from the zlib stream itself when the stream is complete. -

-    int ret;
-    unsigned have;
-    z_stream strm;
-    unsigned char in[CHUNK];
-    unsigned char out[CHUNK];
-
-The initialization of the state is the same, except that there is no compression level, -of course, and two more elements of the structure are initialized. avail_in -and next_in must be initialized before calling inflateInit(). This -is because the application has the option to provide the start of the zlib stream in -order for inflateInit() to have access to information about the compression -method to aid in memory allocation. In the current implementation of zlib -(up through versions 1.2.x), the method-dependent memory allocations are deferred to the first call of -inflate() anyway. However those fields must be initialized since later versions -of zlib that provide more compression methods may take advantage of this interface. -In any case, no decompression is performed by inflateInit(), so the -avail_out and next_out fields do not need to be initialized before calling. -

-Here avail_in is set to zero and next_in is set to Z_NULL to -indicate that no input data is being provided. -


-    /* allocate inflate state */
-    strm.zalloc = Z_NULL;
-    strm.zfree = Z_NULL;
-    strm.opaque = Z_NULL;
-    strm.avail_in = 0;
-    strm.next_in = Z_NULL;
-    ret = inflateInit(&strm);
-    if (ret != Z_OK)
-        return ret;
-
-The outer do-loop decompresses input until inflate() indicates -that it has reached the end of the compressed data and has produced all of the uncompressed -output. This is in contrast to def() which processes all of the input file. -If end-of-file is reached before the compressed data self-terminates, then the compressed -data is incomplete and an error is returned. -

-    /* decompress until deflate stream ends or end of file */
-    do {
-
-We read input data and set the strm structure accordingly. If we've reached the -end of the input file, then we leave the outer loop and report an error, since the -compressed data is incomplete. Note that we may read more data than is eventually consumed -by inflate(), if the input file continues past the zlib stream. -For applications where zlib streams are embedded in other data, this routine would -need to be modified to return the unused data, or at least indicate how much of the input -data was not used, so the application would know where to pick up after the zlib stream. -

-        strm.avail_in = fread(in, 1, CHUNK, source);
-        if (ferror(source)) {
-            (void)inflateEnd(&strm);
-            return Z_ERRNO;
-        }
-        if (strm.avail_in == 0)
-            break;
-        strm.next_in = in;
-
-The inner do-loop has the same function it did in def(), which is to -keep calling inflate() until has generated all of the output it can with the -provided input. -

-        /* run inflate() on input until output buffer not full */
-        do {
-
-Just like in def(), the same output space is provided for each call of inflate(). -

-            strm.avail_out = CHUNK;
-            strm.next_out = out;
-
-Now we run the decompression engine itself. There is no need to adjust the flush parameter, since -the zlib format is self-terminating. The main difference here is that there are -return values that we need to pay attention to. Z_DATA_ERROR -indicates that inflate() detected an error in the zlib compressed data format, -which means that either the data is not a zlib stream to begin with, or that the data was -corrupted somewhere along the way since it was compressed. The other error to be processed is -Z_MEM_ERROR, which can occur since memory allocation is deferred until inflate() -needs it, unlike deflate(), whose memory is allocated at the start by deflateInit(). -

-Advanced applications may use -deflateSetDictionary() to prime deflate() with a set of likely data to improve the -first 32K or so of compression. This is noted in the zlib header, so inflate() -requests that that dictionary be provided before it can start to decompress. Without the dictionary, -correct decompression is not possible. For this routine, we have no idea what the dictionary is, -so the Z_NEED_DICT indication is converted to a Z_DATA_ERROR. -

-inflate() can also return Z_STREAM_ERROR, which should not be possible here, -but could be checked for as noted above for def(). Z_BUF_ERROR does not need to be -checked for here, for the same reasons noted for def(). Z_STREAM_END will be -checked for later. -

-
-The inner do-loop ends when inflate() has no more output as indicated -by not filling the output buffer, just as for deflate(). In this case, we cannot -assert that strm.avail_in will be zero, since the deflate stream may end before the file -does. -

-        } while (strm.avail_out == 0);
-
-The outer do-loop ends when inflate() reports that it has reached the -end of the input zlib stream, has completed the decompression and integrity -check, and has provided all of the output. This is indicated by the inflate() -return value Z_STREAM_END. The inner loop is guaranteed to leave ret -equal to Z_STREAM_END if the last chunk of the input file read contained the end -of the zlib stream. So if the return value is not Z_STREAM_END, the -loop continues to read more input. -

-        /* done when inflate() says it's done */

-
-At this point, decompression successfully completed, or we broke out of the loop due to no -more data being available from the input file. If the last inflate() return value -is not Z_STREAM_END, then the zlib stream was incomplete and a data error -is returned. Otherwise, we return with a happy return value. Of course, inflateEnd() -is called first to avoid a memory leak. -

-}
-
-That ends the routines that directly use zlib. The following routines make this -a command-line program by running data through the above routines from stdin to -stdout, and handling any errors reported by def() or inf(). -

-zerr() is used to interpret the possible error codes from def() -and inf(), as detailed in their comments above, and print out an error message. -Note that these are only a subset of the possible return values from deflate() -and inflate(). -

The compressed file is left open, and can then - be read randomly, having to decompress on the average SPAN/2 uncompressed - bytes before getting to the desired block of data. - - An access point can be created at the start of any deflate block, by saving - the starting file offset and bit of that block, and the 32K bytes of - uncompressed data that precede that block. Also the uncompressed offset of - that block is saved to provide a reference for locating a desired starting - point in the uncompressed stream. deflate_index_build() works by - decompressing the input zlib or gzip stream a block at a time, and at the - end of each block deciding if enough uncompressed data has gone by to - justify the creation of a new access point. If so, that point is saved in a - data structure that grows as needed to accommodate the points. - - To use the index, an offset in the uncompressed data is provided, for which - the latest access point at or preceding that offset is located in the index. - The input file is positioned to the specified location in the index, and if - necessary the first few bits of the compressed data is read from the file. - inflate is initialized with those bits and the 32K of uncompressed data, and - the decompression then proceeds until the desired offset in the file is - reached. Then the decompression continues to read the desired uncompressed - data from the file. - - Another approach would be to generate the index on demand. In that case, - requests for random access reads from the compressed data would try to use - the index, but if a read far enough past the end of the index is required, - then further index entries would be generated and added. - - There is some fair bit of overhead to starting inflation for the random - access, mainly copying the 32K byte dictionary. So if small pieces of the - file are being accessed, it would make sense to implement a cache to hold - some lookahead and avoid many calls to deflate_index_extract() for small - lengths. - - Another way to build an index would be to use inflateCopy(). That would - not be constrained to have access points at block boundaries, but requires - more memory per access point, and also cannot be saved to file due to the - use of pointers in the state.

The state machine is - structured roughly as follows: - - for (;;) switch (state) { - ... - case STATEn: - if (not enough input data or output space to make progress) - return; - ... make progress ... - state = STATEm; - break; - ... - } - - so when inflate() is called again, the same case is attempted again, and - if the appropriate resources are provided, the machine proceeds to the - next state. The NEEDBITS() macro is usually the way the state evaluates - whether it can proceed or should return. NEEDBITS() does the return if - the requested bits are not available. The typical use of the BITS macros - is: - - NEEDBITS(n); - ... do something with BITS(n) ... - DROPBITS(n); - - where NEEDBITS(n) either returns from inflate() if there isn't enough - input left to load n bits into the accumulator, or it continues. BITS(n) - gives the low n bits in the accumulator. When done, DROPBITS(n) drops - the low n bits off the accumulator. INITBITS() clears the accumulator - and sets the number of available bits to zero. BYTEBITS() discards just - enough bits to put the accumulator on a byte boundary. After BYTEBITS() - and a NEEDBITS(8), then BITS(8) would return the next byte in the stream. - - NEEDBITS(n) uses PULLBYTE() to get an available byte of input, or to return - if there is no input available. The decoding of variable length codes uses - PULLBYTE() directly in order to pull just enough bytes to decode the next - code, and no more. - - Some states loop until they get enough input, making sure that enough - state information is maintained to continue the loop where it left off - if NEEDBITS() returns in the loop. For example, want, need, and keep - would all have to actually be part of the saved state in case NEEDBITS() - returns: - - case STATEw: - while (want < need) { - NEEDBITS(n); - keep[want++] = BITS(n); - DROPBITS(n); - } - state = STATEx; - case STATEx: - - As shown above, if the next state is also the next case, then the break - is omitted. - - A state may also return if there is not enough output space available to - complete that state. Those states are copying stored data, writing a - literal byte, and copying a matching string. - - When returning, a "goto inf_leave" is used to update the total counters, - update the check value, and determine whether any progress has been made - during that inflate() call in order to return the proper return code. - Progress is defined as a change in either strm->avail_in or strm->avail_out. - When there is a window, goto inf_leave will update the window with the last - output written. If a goto inf_leave occurs in the middle of decompression - and there is no window currently, goto inf_leave will create one and copy - output to the window for the next call of inflate(). - - In this implementation, the flush parameter of inflate() only affects the - return code (per zlib.h). inflate() always writes as much as possible to - strm->next_out, given the space available and the provided input--the effect - documented in zlib.h of Z_SYNC_FLUSH. Furthermore, inflate() always defers - the allocation of and copying into a sliding window until necessary, which - provides the effect documented in zlib.h for Z_FINISH when the entire input - stream available.

If you have -general questions about zlib, you should see the file "FAQ" found -in the zlib distribution, or at the following location: - http://www.gzip.org/zlib/zlib_faq.html - - - 1. What is ZLIB1.DLL, and how can I get it? - - - ZLIB1.DLL is the official build of zlib as a DLL. - (Please remark the character '1' in the name.) - - Pointers to a precompiled ZLIB1.DLL can be found in the zlib - web site at: - http://www.zlib.net/ - - Applications that link to ZLIB1.DLL can rely on the following - specification: - - * The exported symbols are exclusively defined in the source - files "zlib.h" and "zlib.def", found in an official zlib - source distribution. - * The symbols are exported by name, not by ordinal. - * The exported names are undecorated. - * The calling convention of functions is "C" (CDECL). - * The ZLIB1.DLL binary is linked to MSVCRT.DLL. - - The archive in which ZLIB1.DLL is bundled contains compiled - test programs that must run with a valid build of ZLIB1.DLL. - It is recommended to download the prebuilt DLL from the zlib - web site, instead of building it yourself, to avoid potential - incompatibilities that could be introduced by your compiler - and build settings. If you do build the DLL yourself, please - make sure that it complies with all the above requirements, - and it runs with the precompiled test programs, bundled with - the original ZLIB1.DLL distribution. - - If, for any reason, you need to build an incompatible DLL, - please use a different file name. - - - 2. Why did you change the name of the DLL to ZLIB1.DLL? - What happened to the old ZLIB.DLL? - - - The old ZLIB.DLL, built from zlib-1.1.4 or earlier, required - compilation settings that were incompatible to those used by - a static build. The DLL settings were supposed to be enabled - by defining the macro ZLIB_DLL, before including "zlib.h". - Incorrect handling of this macro was silently accepted at - build time, resulting in two major problems: - - * ZLIB_DLL was missing from the old makefile. When building - the DLL, not all people added it to the build options. In - consequence, incompatible incarnations of ZLIB.DLL started - to circulate around the net. - - * When switching from using the static library to using the - DLL, applications had to define the ZLIB_DLL macro and - to recompile all the sources that contained calls to zlib - functions. Failure to do so resulted in creating binaries - that were unable to run with the official ZLIB.DLL build. - - The only possible solution that we could foresee was to make - a binary-incompatible change in the DLL interface, in order to - remove the dependency on the ZLIB_DLL macro, and to release - the new DLL under a different name. - - We chose the name ZLIB1.DLL, where '1' indicates the major - zlib version number. We hope that we will not have to break - the binary compatibility again, at least not as long as the - zlib-1.x series will last. - - There is still a ZLIB_DLL macro, that can trigger a more - efficient build and use of the DLL, but compatibility no - longer dependents on it. - - - 3. Can I build ZLIB.DLL from the new zlib sources, and replace - an old ZLIB.DLL, that was built from zlib-1.1.4 or earlier? - - - In principle, you can do it by assigning calling convention - keywords to the macros ZEXPORT and ZEXPORTVA. In practice, - it depends on what you mean by "an old ZLIB.DLL", because the - old DLL exists in several mutually-incompatible versions. - You have to find out first what kind of calling convention is - being used in your particular ZLIB.DLL build, and to use the - same one in the new build. If you don't know what this is all - about, you might be better off if you would just leave the old - DLL intact. - - - 4. Can I compile my application using the new zlib interface, and - link it to an old ZLIB.DLL, that was built from zlib-1.1.4 or - earlier? - - - The official answer is "no"; the real answer depends again on - what kind of ZLIB.DLL you have. Even if you are lucky, this - course of action is unreliable. - - If you rebuild your application and you intend to use a newer - version of zlib (post- 1.1.4), it is strongly recommended to - link it to the new ZLIB1.DLL. - - - 5. Why are the zlib symbols exported by name, and not by ordinal? - - - Although exporting symbols by ordinal is a little faster, it - is risky. Any single glitch in the maintenance or use of the - DEF file that contains the ordinals can result in incompatible - builds and frustrating crashes. Simply put, the benefits of - exporting symbols by ordinal do not justify the risks. - - Technically, it should be possible to maintain ordinals in - the DEF file, and still export the symbols by name. Ordinals - exist in every DLL, and even if the dynamic linking performed - at the DLL startup is searching for names, ordinals serve as - hints, for a faster name lookup. However, if the DEF file - contains ordinals, the Microsoft linker automatically builds - an implib that will cause the executables linked to it to use - those ordinals, and not the names. It is interesting to - notice that the GNU linker for Win32 does not suffer from this - problem. - - It is possible to avoid the DEF file if the exported symbols - are accompanied by a "__declspec(dllexport)" attribute in the - source files. You can do this in zlib by predefining the - ZLIB_DLL macro. - - - 6. I see that the ZLIB1.DLL functions use the "C" (CDECL) calling - convention. Why not use the STDCALL convention? - STDCALL is the standard convention in Win32, and I need it in - my Visual Basic project! - - (For readability, we use CDECL to refer to the convention - triggered by the "__cdecl" keyword, STDCALL to refer to - the convention triggered by "__stdcall", and FASTCALL to - refer to the convention triggered by "__fastcall".) - - - Most of the native Windows API functions (without varargs) use - indeed the WINAPI convention (which translates to STDCALL in - Win32), but the standard C functions use CDECL. If a user - application is intrinsically tied to the Windows API (e.g. - it calls native Windows API functions such as CreateFile()), - sometimes it makes sense to decorate its own functions with - WINAPI. But if ANSI C or POSIX portability is a goal (e.g. - it calls standard C functions such as fopen()), it is not a - sound decision to request the inclusion of , or to - use non-ANSI constructs, for the sole purpose to make the user - functions STDCALL-able. - - The functionality offered by zlib is not in the category of - "Windows functionality", but is more like "C functionality". - - Technically, STDCALL is not bad; in fact, it is slightly - faster than CDECL, and it works with variable-argument - functions, just like CDECL. It is unfortunate that, in spite - of using STDCALL in the Windows API, it is not the default - convention used by the C compilers that run under Windows. - The roots of the problem reside deep inside the unsafety of - the K&R-style function prototypes, where the argument types - are not specified; but that is another story for another day. - - The remaining fact is that CDECL is the default convention. - Even if an explicit convention is hard-coded into the function - prototypes inside C headers, problems may appear. The - necessity to expose the convention in users' callbacks is one - of these problems. - - The calling convention issues are also important when using - zlib in other programming languages. Some of them, like Ada - (GNAT) and Fortran (GNU G77), have C bindings implemented - initially on Unix, and relying on the C calling convention. - On the other hand, the pre- .NET versions of Microsoft Visual - Basic require STDCALL, while Borland Delphi prefers, although - it does not require, FASTCALL. - - In fairness to all possible uses of zlib outside the C - programming language, we choose the default "C" convention. - Anyone interested in different bindings or conventions is - encouraged to maintain specialized projects. The "contrib/" - directory from the zlib distribution already holds a couple - of foreign bindings, such as Ada, C++, and Delphi. - - - 7. I need a DLL for my Visual Basic project. What can I do? - - - Define the ZLIB_WINAPI macro before including "zlib.h", when - building both the DLL and the user application (except that - you don't need to define anything when using the DLL in Visual - Basic). The ZLIB_WINAPI macro will switch on the WINAPI - (STDCALL) convention. The name of this DLL must be different - than the official ZLIB1.DLL. - - Gilles Vollant has contributed a build named ZLIBWAPI.DLL, - with the ZLIB_WINAPI macro turned on, and with the minizip - functionality built in. For more information, please read - the notes inside "contrib/vstudio/readme.txt", found in the - zlib distribution. - - - 8. I need to use zlib in my Microsoft .NET project. What can I - do? - - - Henrik Ravn has contributed a .NET wrapper around zlib. Look - into contrib/dotzlib/, inside the zlib distribution. - - - 9. If my application uses ZLIB1.DLL, should I link it to - MSVCRT.DLL? Why? - - - It is not required, but it is recommended to link your - application to MSVCRT.DLL, if it uses ZLIB1.DLL. - - The executables (.EXE, .DLL, etc.) that are involved in the - same process and are using the C run-time library (i.e. they - are calling standard C functions), must link to the same - library. There are several libraries in the Win32 system: - CRTDLL.DLL, MSVCRT.DLL, the static C libraries, etc. - Since ZLIB1.DLL is linked to MSVCRT.DLL, the executables that - depend on it should also be linked to MSVCRT.DLL. - - -10. Why are you saying that ZLIB1.DLL and my application should - be linked to the same C run-time (CRT) library? I linked my - application and my DLLs to different C libraries (e.g. my - application to a static library, and my DLLs to MSVCRT.DLL), - and everything works fine. - - - If a user library invokes only pure Win32 API (accessible via - and the related headers), its DLL build will work - in any context. But if this library invokes standard C API, - things get more complicated. - - There is a single Win32 library in a Win32 system. Every - function in this library resides in a single DLL module, that - is safe to call from anywhere. On the other hand, there are - multiple versions of the C library, and each of them has its - own separate internal state. Standalone executables and user - DLLs that call standard C functions must link to a C run-time - (CRT) library, be it static or shared (DLL). Intermixing - occurs when an executable (not necessarily standalone) and a - DLL are linked to different CRTs, and both are running in the - same process. - - Intermixing multiple CRTs is possible, as long as their - internal states are kept intact. The Microsoft Knowledge Base - articles KB94248 "HOWTO: Use the C Run-Time" and KB140584 - "HOWTO: Link with the Correct C Run-Time (CRT) Library" - mention the potential problems raised by intermixing. - - If intermixing works for you, it's because your application - and DLLs are avoiding the corruption of each of the CRTs' - internal states, maybe by careful design, or maybe by fortune. - - Also note that linking ZLIB1.DLL to non-Microsoft CRTs, such - as those provided by Borland, raises similar problems. - - -11. Why are you linking ZLIB1.DLL to MSVCRT.DLL? - - - MSVCRT.DLL exists on every Windows 95 with a new service pack - installed, or with Microsoft Internet Explorer 4 or later, and - on all other Windows 4.x or later (Windows 98, Windows NT 4, - or later). It is freely distributable; if not present in the - system, it can be downloaded from Microsoft or from other - software provider for free. - - The fact that MSVCRT.DLL does not exist on a virgin Windows 95 - is not so problematic. Windows 95 is scarcely found nowadays, - Microsoft ended its support a long time ago, and many recent - applications from various vendors, including Microsoft, do not - even run on it. Furthermore, no serious user should run - Windows 95 without a proper update installed. - - -12. Why are you not linking ZLIB1.DLL to - <> ? - - - We considered and abandoned the following alternatives: - - * Linking ZLIB1.DLL to a static C library (LIBC.LIB, or - LIBCMT.LIB) is not a good option. People are using the DLL - mainly to save disk space. If you are linking your program - to a static C library, you may as well consider linking zlib - in statically, too. - - * Linking ZLIB1.DLL to CRTDLL.DLL looks appealing, because - CRTDLL.DLL is present on every Win32 installation. - Unfortunately, it has a series of problems: it does not - work properly with Microsoft's C++ libraries, it does not - provide support for 64-bit file offsets, (and so on...), - and Microsoft discontinued its support a long time ago. - - * Linking ZLIB1.DLL to MSVCR70.DLL or MSVCR71.DLL, supplied - with the Microsoft .NET platform, and Visual C++ 7.0/7.1, - raises problems related to the status of ZLIB1.DLL as a - system component. According to the Microsoft Knowledge Base - article KB326922 "INFO: Redistribution of the Shared C - Runtime Component in Visual C++ .NET", MSVCR70.DLL and - MSVCR71.DLL are not supposed to function as system DLLs, - because they may clash with MSVCRT.DLL. Instead, the - application's installer is supposed to put these DLLs - (if needed) in the application's private directory. - If ZLIB1.DLL depends on a non-system runtime, it cannot - function as a redistributable system component. - - * Linking ZLIB1.DLL to non-Microsoft runtimes, such as - Borland's, or Cygwin's, raises problems related to the - reliable presence of these runtimes on Win32 systems. - It's easier to let the DLL build of zlib up to the people - who distribute these runtimes, and who may proceed as - explained in the answer to Question 14. - - -13. If ZLIB1.DLL cannot be linked to MSVCR70.DLL or MSVCR71.DLL, - how can I build/use ZLIB1.DLL in Microsoft Visual C++ 7.0 - (Visual Studio .NET) or newer? - - - Due to the problems explained in the Microsoft Knowledge Base - article KB326922 (see the previous answer), the C runtime that - comes with the VC7 environment is no longer considered a - system component. That is, it should not be assumed that this - runtime exists, or may be installed in a system directory. - Since ZLIB1.DLL is supposed to be a system component, it may - not depend on a non-system component. - - In order to link ZLIB1.DLL and your application to MSVCRT.DLL - in VC7, you need the library of Visual C++ 6.0 or older. If - you don't have this library at hand, it's probably best not to - use ZLIB1.DLL. - - We are hoping that, in the future, Microsoft will provide a - way to build applications linked to a proper system runtime, - from the Visual C++ environment. Until then, you have a - couple of alternatives, such as linking zlib in statically. - If your application requires dynamic linking, you may proceed - as explained in the answer to Question 14. - - -14. I need to link my own DLL build to a CRT different than - MSVCRT.DLL. What can I do? - - - Feel free to rebuild the DLL from the zlib sources, and link - it the way you want. You should, however, clearly state that - your build is unofficial. You should give it a different file - name, and/or install it in a private directory that can be - accessed by your application only, and is not visible to the - others (i.e. it's neither in the PATH, nor in the SYSTEM or - SYSTEM32 directories). Otherwise, your build may clash with - applications that link to the official build. - - For example, in Cygwin, zlib is linked to the Cygwin runtime - CYGWIN1.DLL, and it is distributed under the name CYGZ.DLL. - - -15. May I include additional pieces of code that I find useful, - link them in ZLIB1.DLL, and export them? - - - No. A legitimate build of ZLIB1.DLL must not include code - that does not originate from the official zlib source code. - But you can make your own private DLL build, under a different - file name, as suggested in the previous answer. - - For example, zlib is a part of the VCL library, distributed - with Borland Delphi and C++ Builder. The DLL build of VCL - is a redistributable file, named VCLxx.DLL. - - -16. May I remove some functionality out of ZLIB1.DLL, by enabling - macros like NO_GZCOMPRESS or NO_GZIP at compile time? - - - No. A legitimate build of ZLIB1.DLL must provide the complete - zlib functionality, as implemented in the official zlib source - code. But you can make your own private DLL build, under a - different file name, as suggested in the previous answer. - - -17. I made my own ZLIB1.DLL build. Can I test it for compliance? - - - We prefer that you download the official DLL from the zlib - web site.

It may introduce - some output latency (reading input without producing any output) except when - forced to flush. - - The detailed semantics are as follows. deflate performs one or both of the - following actions: - - - Compress more input starting at next_in and update next_in and avail_in - accordingly. If not all input can be processed (because there is not - enough room in the output buffer), next_in and avail_in are updated and - processing will resume at this point for the next call of deflate(). - - - Generate more output starting at next_out and update next_out and avail_out - accordingly. This action is forced if the parameter flush is non zero. - Forcing flush frequently degrades the compression ratio, so this parameter - should be set only when necessary. Some output may be provided even if - flush is zero. - - Before the call of deflate(), the application should ensure that at least - one of the actions is possible, by providing more input and/or consuming more - output, and updating avail_in or avail_out accordingly; avail_out should - never be zero before the call. The application can consume the compressed - output when it wants, for example when the output buffer is full (avail_out - == 0), or after each call of deflate(). If deflate returns Z_OK and with - zero avail_out, it must be called again after making room in the output - buffer because there might be more output pending. See deflatePending(), - which can be used if desired to determine whether or not there is more output - in that case. - - Normally the parameter flush is set to Z_NO_FLUSH, which allows deflate to - decide how much data to accumulate before producing output, in order to - maximize compression. - - If the parameter flush is set to Z_SYNC_FLUSH, all pending output is - flushed to the output buffer and the output is aligned on a byte boundary, so - that the decompressor can get all input data available so far. (In - particular avail_in is zero after the call if enough output space has been - provided before the call.) Flushing may degrade compression for some - compression algorithms and so it should be used only when necessary. This - completes the current deflate block and follows it with an empty stored block - that is three bits plus filler bits to the next byte, followed by four bytes - (00 00 ff ff). - - If flush is set to Z_PARTIAL_FLUSH, all pending output is flushed to the - output buffer, but the output is not aligned to a byte boundary. All of the - input data so far will be available to the decompressor, as for Z_SYNC_FLUSH. - This completes the current deflate block and follows it with an empty fixed - codes block that is 10 bits long. This assures that enough bytes are output - in order for the decompressor to finish the block before the empty fixed - codes block. - - If flush is set to Z_BLOCK, a deflate block is completed and emitted, as - for Z_SYNC_FLUSH, but the output is not aligned on a byte boundary, and up to - seven bits of the current block are held to be written as the next byte after - the next deflate block is completed. In this case, the decompressor may not - be provided enough bits at this point in order to complete decompression of - the data provided so far to the compressor. It may need to wait for the next - block to be emitted. This is for advanced applications that need to control - the emission of deflate blocks. - - If flush is set to Z_FULL_FLUSH, all output is flushed as with - Z_SYNC_FLUSH, and the compression state is reset so that decompression can - restart from this point if previous compressed data has been damaged or if - random access is desired. Using Z_FULL_FLUSH too often can seriously degrade - compression. - - If deflate returns with avail_out == 0, this function must be called again - with the same value of the flush parameter and more output space (updated - avail_out), until the flush is complete (deflate returns with non-zero - avail_out). In the case of a Z_FULL_FLUSH or Z_SYNC_FLUSH, make sure that - avail_out is greater than six to avoid repeated flush markers due to - avail_out == 0 on return. - - If the parameter flush is set to Z_FINISH, pending input is processed, - pending output is flushed and deflate returns with Z_STREAM_END if there was - enough output space. If deflate returns with Z_OK or Z_BUF_ERROR, this - function must be called again with Z_FINISH and more output space (updated - avail_out) but no more input data, until it returns with Z_STREAM_END or an - error. After deflate has returned Z_STREAM_END, the only possible operations - on the stream are deflateReset or deflateEnd. - - Z_FINISH can be used in the first deflate call after deflateInit if all the - compression is to be done in a single step. In order to complete in one - call, avail_out must be at least the value returned by deflateBound (see - below). Then deflate is guaranteed to return Z_STREAM_END. If not enough - output space is provided, deflate will not return Z_STREAM_END, and it must - be called again as described above. - - deflate() sets strm->adler to the Adler-32 checksum of all input read - so far (that is, total_in bytes). If a gzip stream is being generated, then - strm->adler will be the CRC-32 checksum of the input read so far. (See - deflateInit2 below.) - - deflate() may update strm->data_type if it can make a good guess about - the input data type (Z_BINARY or Z_TEXT). If in doubt, the data is - considered binary. This field is only for information purposes and does not - affect the compression algorithm in any manner. - - deflate() returns Z_OK if some progress has been made (more input - processed or more output produced), Z_STREAM_END if all input has been - consumed and all output has been produced (only when flush is set to - Z_FINISH), Z_STREAM_ERROR if the stream state was inconsistent (for example - if next_in or next_out was Z_NULL or the state was inadvertently written over - by the application), or Z_BUF_ERROR if no progress is possible (for example - avail_in or avail_out was zero).

It may introduce - some output latency (reading input without producing any output) except when - forced to flush. - - The detailed semantics are as follows. inflate performs one or both of the - following actions: - - - Decompress more input starting at next_in and update next_in and avail_in - accordingly. If not all input can be processed (because there is not - enough room in the output buffer), then next_in and avail_in are updated - accordingly, and processing will resume at this point for the next call of - inflate(). - - - Generate more output starting at next_out and update next_out and avail_out - accordingly. inflate() provides as much output as possible, until there is - no more input data or no more space in the output buffer (see below about - the flush parameter). - - Before the call of inflate(), the application should ensure that at least - one of the actions is possible, by providing more input and/or consuming more - output, and updating the next_* and avail_* values accordingly. If the - caller of inflate() does not provide both available input and available - output space, it is possible that there will be no progress made. The - application can consume the uncompressed output when it wants, for example - when the output buffer is full (avail_out == 0), or after each call of - inflate(). If inflate returns Z_OK and with zero avail_out, it must be - called again after making room in the output buffer because there might be - more output pending. - - The flush parameter of inflate() can be Z_NO_FLUSH, Z_SYNC_FLUSH, Z_FINISH, - Z_BLOCK, or Z_TREES. Z_SYNC_FLUSH requests that inflate() flush as much - output as possible to the output buffer. Z_BLOCK requests that inflate() - stop if and when it gets to the next deflate block boundary. When decoding - the zlib or gzip format, this will cause inflate() to return immediately - after the header and before the first block. When doing a raw inflate, - inflate() will go ahead and process the first block, and will return when it - gets to the end of that block, or when it runs out of data. - - The Z_BLOCK option assists in appending to or combining deflate streams. - To assist in this, on return inflate() always sets strm->data_type to the - number of unused bits in the last byte taken from strm->next_in, plus 64 if - inflate() is currently decoding the last block in the deflate stream, plus - 128 if inflate() returned immediately after decoding an end-of-block code or - decoding the complete header up to just before the first byte of the deflate - stream. The end-of-block will not be indicated until all of the uncompressed - data from that block has been written to strm->next_out. The number of - unused bits may in general be greater than seven, except when bit 7 of - data_type is set, in which case the number of unused bits will be less than - eight. data_type is set as noted here every time inflate() returns for all - flush options, and so can be used to determine the amount of currently - consumed input in bits. - - The Z_TREES option behaves as Z_BLOCK does, but it also returns when the - end of each deflate block header is reached, before any actual data in that - block is decoded. This allows the caller to determine the length of the - deflate block header for later use in random access within a deflate block. - 256 is added to the value of strm->data_type when inflate() returns - immediately after reaching the end of the deflate block header. - - inflate() should normally be called until it returns Z_STREAM_END or an - error. However if all decompression is to be performed in a single step (a - single call of inflate), the parameter flush should be set to Z_FINISH. In - this case all pending input is processed and all pending output is flushed; - avail_out must be large enough to hold all of the uncompressed data for the - operation to complete. (The size of the uncompressed data may have been - saved by the compressor for this purpose.) The use of Z_FINISH is not - required to perform an inflation in one step. However it may be used to - inform inflate that a faster approach can be used for the single inflate() - call. Z_FINISH also informs inflate to not maintain a sliding window if the - stream completes, which reduces inflate's memory footprint. If the stream - does not complete, either because not all of the stream is provided or not - enough output space is provided, then a sliding window will be allocated and - inflate() can be called again to continue the operation as if Z_NO_FLUSH had - been used. - - In this implementation, inflate() always flushes as much output as - possible to the output buffer, and always uses the faster approach on the - first call. So the effects of the flush parameter in this implementation are - on the return value of inflate() as noted below, when inflate() returns early - when Z_BLOCK or Z_TREES is used, and when inflate() avoids the allocation of - memory for a sliding window when Z_FINISH is used. - - If a preset dictionary is needed after this call (see inflateSetDictionary - below), inflate sets strm->adler to the Adler-32 checksum of the dictionary - chosen by the compressor and returns Z_NEED_DICT; otherwise it sets - strm->adler to the Adler-32 checksum of all output produced so far (that is, - total_out bytes) and returns Z_OK, Z_STREAM_END or an error code as described - below. At the end of the stream, inflate() checks that its computed Adler-32 - checksum is equal to that saved by the compressor and returns Z_STREAM_END - only if the checksum is correct. - - inflate() can decompress and check either zlib-wrapped or gzip-wrapped - deflate data. The header type is detected automatically, if requested when - initializing with inflateInit2(). Any information contained in the gzip - header is not retained unless inflateGetHeader() is used. When processing - gzip-wrapped deflate data, strm->adler32 is set to the CRC-32 of the output - produced so far. The CRC-32 is checked against the gzip trailer, as is the - uncompressed length, modulo 2^32. - - inflate() returns Z_OK if some progress has been made (more input processed - or more output produced), Z_STREAM_END if the end of the compressed data has - been reached and all uncompressed output has been produced, Z_NEED_DICT if a - preset dictionary is needed at this point, Z_DATA_ERROR if the input data was - corrupted (input stream not conforming to the zlib format or incorrect check - value, in which case strm->msg points to a string with a more specific - error), Z_STREAM_ERROR if the stream structure was inconsistent (for example - next_in or next_out was Z_NULL, or the state was inadvertently written over - by the application), Z_MEM_ERROR if there was not enough memory, Z_BUF_ERROR - if no progress was possible or if there was not enough room in the output - buffer when Z_FINISH is used. Note that Z_BUF_ERROR is not fatal, and - inflate() can be called again with more input and more output space to - continue decompressing.

The remedy is to not use 8 - with deflateInit2() with this initialization, or at least in that case use 9 - with inflateInit2(). - - windowBits can also be -8..-15 for raw deflate.
