It supports most -.B gcc -options. -.PP -Unlike -.BR gcc , -.B klcc -compiles with optimization on by default. Furthermore, the -optimization level used depends on whether or not -.B \-g -is specified, since -.B klcc -frequently uses options in the normal case which makes debugging -impossible. Therefore, compile without -.BR \-g , -.BR \-O , -.B \-f -or -.B \-m -option to use the default optimization level; this will generally -result in the smallest binaries. You may want to use -.B \-s -when linking, however. Use -.B \-O0 -to compile without any optimization whatsoever; this may not work depending -on the version of -.B gcc -used. -.PP -Use the -.B \-shared -or -.B \-static -option to compile for and link against shared or static klibc.

Where can I get a Visual Basic interface to zlib? - - See - * http://www.winimage.com/zLibDll/ - * http://www.dogma.net/markn/articles/zlibtool/zlibtool.htm - * contrib/visual-basic.txt in the zlib distribution - - 4. compress() returns Z_BUF_ERROR - - Make sure that before the call of compress, the length of the compressed - buffer is equal to the total size of the compressed buffer and not - zero. For Visual Basic, check that this parameter is passed by reference - ("as any"), not by value ("as long"). - - 5. deflate() or inflate() returns Z_BUF_ERROR - - Before making the call, make sure that avail_in and avail_out are not - zero. When setting the parameter flush equal to Z_FINISH, also make sure - that avail_out is big enough to allow processing all pending input. - Note that a Z_BUF_ERROR is not fatal--another call to deflate() or - inflate() can be made with more input or output space. A Z_BUF_ERROR - may in fact be unavoidable depending on how the functions are used, since - it is not possible to tell whether or not there is more output pending - when strm.avail_out returns with zero. - - 6. Where's the zlib documentation (man pages, etc.)? - - It's in zlib.h for the moment, and Francis S. Lin has converted it to a - web page zlib.html. Volunteers to transform this to Unix-style man pages, - please contact Jean-loup Gailly (jloup@gzip.org). Examples of zlib usage - are in the files example.c and minigzip.c. - - 7. Why don't you use GNU autoconf or libtool or ...? - - Because we would like to keep zlib as a very small and simple - package. zlib is rather portable and doesn't need much configuration. - - 8. I found a bug in zlib. - - Most of the time, such problems are due to an incorrect usage of - zlib. Please try to reproduce the problem with a small program and send - the corresponding source to us at zlib@gzip.org . Do not send - multi-megabyte data files without prior agreement. - - 9. Why do I get "undefined reference to gzputc"? - - If "make test" produces something like - - example.o(.text+0x154): undefined reference to `gzputc' - - check that you don't have old files libz.* in /usr/lib, /usr/local/lib or - /usr/X11R6/lib. Remove any old versions, then do "make install". - -10. I need a Delphi interface to zlib. - - See the contrib/delphi directory in the zlib distribution. - -11. Can zlib handle .zip archives? - - See the directory contrib/minizip in the zlib distribution. - -12. Can zlib handle .Z files? - - No, sorry. You have to spawn an uncompress or gunzip subprocess, or adapt - the code of uncompress on your own. - -13. How can I make a Unix shared library? - - make clean - ./configure -s - make - -14. How do I install a shared zlib library on Unix? - - make install - - However, many flavors of Unix come with a shared zlib already installed. - Before going to the trouble of compiling a shared version of zlib and - trying to install it, you may want to check if it's already there! If you - can #include <zlib.h>, it's there. The -lz option will probably link to it. - -15. I have a question about OttoPDF - - We are not the authors of OttoPDF. The real author is on the OttoPDF web - site Joel Hainley jhainley@myndkryme.com. - -16. 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. - -17. 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. - -18. 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. - - Note that you cannot specify special gzip header contents (e.g. a file - name or modification date), nor will inflate tell you what was in the - gzip header. If you need to customize the header or see what's in it, - you can use the raw deflate and inflate operations and the crc32() - function and roll your own gzip encoding and decoding. Read the gzip - RFC 1952 for details of the header and trailer format. - -19. 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. - -20. Can I use zlib in my commercial application? - - Yes. Please read the license in zlib.h. - -21. Is zlib under the GNU license? - - No. Please read the license in zlib.h. - -22. 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. - -23. Will zlib work on a big-endian or little-endian architecture, and can I - exchange compressed data between them? - - Yes and yes. - -24. Will zlib work on a 64-bit machine? - - It should. It has been tested on 64-bit machines, and has no dependence - on any data types being limited to 32-bits in length. If you have any - difficulties, please provide a complete problem report to zlib@gzip.org - -25. 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. - -26. 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. - -27. Does zlib work on MVS, OS/390, CICS, etc.? - - We don't know for sure. We have heard occasional reports of success on - these systems. If you do use it on one of these, please provide us with - a report, instructions, and patches that we can reference when we get - these questions. Thanks. - -28. 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. - -29. 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 - -30. 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. - -31. Does zlib have any security vulnerabilities? - - The only one that we are aware of is potentially in gzprintf(). If zlib - is compiled to use sprintf() or vsprintf(), then there is no protection - against a buffer overflow of a 4K string space, other than the caller of - gzprintf() assuring that the output will not exceed 4K. On the other - hand, if zlib is compiled to use snprintf() or vsnprintf(), which should - normally be the case, then there is no vulnerability. The ./configure - script will display warnings if an insecure variation of sprintf() will - be used by gzprintf(). Also the zlibCompileFlags() function will return - information on what variant of sprintf() is used by gzprintf(). - - If you don't have snprintf() or vsnprintf() and would like one, you can - find a portable implementation here: - - http://www.ijs.si/software/snprintf/ - - Note that you should be using the most recent version of zlib. Versions - 1.1.3 and before were subject to a double-free vulnerability. - -32. Is there a Java version of zlib? - - Probably what you want is to use zlib in Java. zlib is already included - as part of the Java SDK in the java.util.zip package. If you really want - a version of zlib written in the Java language, look on the zlib home - page for links: http://www.zlib.org/ - -33. I get this or that compiler or source-code scanner warning when I crank it - up to maximally-pendantic. Can't you guys write proper code? - - Many years ago, we gave up attempting to avoid warnings on every compiler - in the universe. It just got to be a waste of time, and some compilers - were downright silly. So now, we simply make sure that the code always - works. - -34. 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. - -35. 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 gpg ( http://www.gnupg.org/ ) which already includes zlib compression. - For PKZIP compatible "encryption", look at http://www.info-zip.org/ - -36. What's the difference between the "gzip" and "deflate" HTTP 1.1 encodings? - - "gzip" is the gzip format, and "deflate" is the zlib format. They should - probably have called the second one "zlib" instead to avoid confusion - with the raw deflate compressed data format. While the HTTP 1.1 RFC 2616 - correctly points to the zlib specification in RFC 1950 for the "deflate" - transfer encoding, there have been reports of servers and browsers that - incorrectly produce or expect raw deflate data per the deflate - specficiation in RFC 1951, most notably Microsoft. So even though the - "deflate" transfer encoding using the zlib format would be the more - efficient approach (and in fact exactly what the zlib format was designed - for), using the "gzip" transfer encoding is probably more reliable due to - an unfortunate choice of name on the part of the HTTP 1.1 authors. - - Bottom line: use the gzip format for HTTP 1.1 encoding. - -37. 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. - -38. 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.

Compression algorithm (deflate) - -The deflation algorithm used by gzip (also zip and zlib) is a variation of -LZ77 (Lempel-Ziv 1977, see reference below). It finds duplicated strings in -the input data. The second occurrence of a string is replaced by a -pointer to the previous string, in the form of a pair (distance, -length). Distances are limited to 32K bytes, and lengths are limited -to 258 bytes. When a string does not occur anywhere in the previous -32K bytes, it is emitted as a sequence of literal bytes. (In this -description, `string' must be taken as an arbitrary sequence of bytes, -and is not restricted to printable characters.) - -Literals or match lengths are compressed with one Huffman tree, and -match distances are compressed with another tree. The trees are stored -in a compact form at the start of each block. The blocks can have any -size (except that the compressed data for one block must fit in -available memory). A block is terminated when deflate() determines that -it would be useful to start another block with fresh trees. (This is -somewhat similar to the behavior of LZW-based _compress_.) - -Duplicated strings are found using a hash table. All input strings of -length 3 are inserted in the hash table. A hash index is computed for -the next 3 bytes. If the hash chain for this index is not empty, all -strings in the chain are compared with the current input string, and -the longest match is selected. - -The hash chains are searched starting with the most recent strings, to -favor small distances and thus take advantage of the Huffman encoding. -The hash chains are singly linked. There are no deletions from the -hash chains, the algorithm simply discards matches that are too old. - -To avoid a worst-case situation, very long hash chains are arbitrarily -truncated at a certain length, determined by a runtime option (level -parameter of deflateInit). So deflate() does not always find the longest -possible match but generally finds a match which is long enough. - -deflate() also defers the selection of matches with a lazy evaluation -mechanism. After a match of length N has been found, deflate() searches for -a longer match at the next input byte. If a longer match is found, the -previous match is truncated to a length of one (thus producing a single -literal byte) and the process of lazy evaluation begins again. Otherwise, -the original match is kept, and the next match search is attempted only N -steps later. - -The lazy match evaluation is also subject to a runtime parameter. If -the current match is long enough, deflate() reduces the search for a longer -match, thus speeding up the whole process. If compression ratio is more -important than speed, deflate() attempts a complete second search even if -the first match is already long enough. - -The lazy match evaluation is not performed for the fastest compression -modes (level parameter 1 to 3). For these fast modes, new strings -are inserted in the hash table only when no match was found, or -when the match is not too long. This degrades the compression ratio -but saves time since there are both fewer insertions and fewer searches. - - -2. Decompression algorithm (inflate) - -2.1 Introduction - -The key question is how to represent a Huffman code (or any prefix code) so -that you can decode fast. The most important characteristic is that shorter -codes are much more common than longer codes, so pay attention to decoding the -short codes fast, and let the long codes take longer to decode. - -inflate() sets up a first level table that covers some number of bits of -input less than the length of longest code. It gets that many bits from the -stream, and looks it up in the table. The table will tell if the next -code is that many bits or less and how many, and if it is, it will tell -the value, else it will point to the next level table for which inflate() -grabs more bits and tries to decode a longer code. - -How many bits to make the first lookup is a tradeoff between the time it -takes to decode and the time it takes to build the table. If building the -table took no time (and if you had infinite memory), then there would only -be a first level table to cover all the way to the longest code. However, -building the table ends up taking a lot longer for more bits since short -codes are replicated many times in such a table. What inflate() does is -simply to make the number of bits in the first table a variable, and then -to set that variable for the maximum speed. - -For inflate, which has 286 possible codes for the literal/length tree, the size -of the first table is nine bits. Also the distance trees have 30 possible -values, and the size of the first table is six bits. Note that for each of -those cases, the table ended up one bit longer than the ``average'' code -length, i.e. the code length of an approximately flat code which would be a -little more than eight bits for 286 symbols and a little less than five bits -for 30 symbols. - - -2.2 More details on the inflate table lookup - -Ok, you want to know what this cleverly obfuscated inflate tree actually -looks like. You are correct that it's not a Huffman tree. It is simply a -lookup table for the first, let's say, nine bits of a Huffman symbol. The -symbol could be as short as one bit or as long as 15 bits. If a particular -symbol is shorter than nine bits, then that symbol's translation is duplicated -in all those entries that start with that symbol's bits. For example, if the -symbol is four bits, then it's duplicated 32 times in a nine-bit table. If a -symbol is nine bits long, it appears in the table once. - -If the symbol is longer than nine bits, then that entry in the table points -to another similar table for the remaining bits. Again, there are duplicated -entries as needed. The idea is that most of the time the symbol will be short -and there will only be one table look up. (That's whole idea behind data -compression in the first place.) For the less frequent long symbols, there -will be two lookups. If you had a compression method with really long -symbols, you could have as many levels of lookups as is efficient. For -inflate, two is enough. - -So a table entry either points to another table (in which case nine bits in -the above example are gobbled), or it contains the translation for the symbol -and the number of bits to gobble. Then you start again with the next -ungobbled bit. - -You may wonder: why not just have one lookup table for how ever many bits the -longest symbol is? The reason is that if you do that, you end up spending -more time filling in duplicate symbol entries than you do actually decoding. -At least for deflate's output that generates new trees every several 10's of -kbytes. You can imagine that filling in a 2^15 entry table for a 15-bit code -would take too long if you're only decoding several thousand symbols. At the -other extreme, you could make a new table for every bit in the code. In fact, -that's essentially a Huffman tree. But then you spend two much time -traversing the tree while decoding, even for short symbols. - -So the number of bits for the first lookup table is a trade of the time to -fill out the table vs. the time spent looking at the second level and above of -the table. - -Here is an example, scaled down: - -The code being decoded, with 10 symbols, from 1 to 6 bits long: - -A: 0 -B: 10 -C: 1100 -D: 11010 -E: 11011 -F: 11100 -G: 11101 -H: 11110 -I: 111110 -J: 111111 - -Let's make the first table three bits long (eight entries): - -000: A,1 -001: A,1 -010: A,1 -011: A,1 -100: B,2 -101: B,2 -110: -> table X (gobble 3 bits) -111: -> table Y (gobble 3 bits) - -Each entry is what the bits decode as and how many bits that is, i.e. how -many bits to gobble. Or the entry points to another table, with the number of -bits to gobble implicit in the size of the table. - -Table X is two bits long since the longest code starting with 110 is five bits -long: - -00: C,1 -01: C,1 -10: D,2 -11: E,2 - -Table Y is three bits long since the longest code starting with 111 is six -bits long: - -000: F,2 -001: F,2 -010: G,2 -011: G,2 -100: H,2 -101: H,2 -110: I,3 -111: J,3 - -So what we have here are three tables with a total of 20 entries that had to -be constructed. That's compared to 64 entries for a single table. Or -compared to 16 entries for a Huffman tree (six two entry tables and one four -entry table). Assuming that the code ideally represents the probability of -the symbols, it takes on the average 1.25 lookups per symbol. That's compared -to one lookup for the single table, or 1.66 lookups per symbol for the -Huffman tree. - -There, I think that gives you a picture of what's going on. For inflate, the -meaning of a particular symbol is often more than just a letter. It can be a -byte (a "literal"), or it can be either a length or a distance which -indicates a base value and a number of bits to fetch after the code that is -added to the base value. Or it might be the special end-of-block code. The -data structures created in inftrees.c try to encode all that information -compactly in the tables. - - -Jean-loup Gailly Mark Adler -jloup@gzip.org madler@alumni.caltech.edu - - -References: - -[LZ77] Ziv J., Lempel A., ``A Universal Algorithm for Sequential Data -Compression,'' IEEE Transactions on Information Theory, Vol. 23, No. 3, -pp. 337-343. - -``DEFLATE Compressed Data Format Specification'' available in -http://www.ietf.org/rfc/rfc1951.txt diff --git a/klibc/klibc/zlib/compress.c b/klibc/klibc/zlib/compress.c deleted file mode 100644 index 3f4b44266a..0000000000 --- a/klibc/klibc/zlib/compress.c +++ /dev/null @@ -1,79 +0,0 @@ -/* compress.c -- compress a memory buffer - * Copyright (C) 1995-2002 Jean-loup Gailly. - * For conditions of distribution and use, see copyright notice in zlib.h - */ - -/* @(#) $Id: compress.c,v 1.1 2005/02/27 23:15:39 hpa Exp $ */ - -#define ZLIB_INTERNAL -#include "zlib.h" - -/* =========================================================================== - Compresses the source buffer into the destination buffer.

* 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.

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. So the only thing the flush parameter actually does is: - when flush is set to Z_FINISH, inflate() cannot return Z_OK.
