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.

-
-LICENSE_1_0.txt - License file.
-readme.txt - This file.
-DotZLib.chm - Class library documentation
-DotZLib.build - NAnt build file
-DotZLib.sln - Microsoft Visual Studio 2003 solution file
-
-DotZLib\*.cs - Source files for the class library
-
-Unit tests:
------------
-The file DotZLib/UnitTests.cs contains unit tests for use with NUnit 2.1 or higher.
-To include unit tests in the build, define nunit before building.
-
-
-Build instructions:
--------------------
-
-1. Using Visual Studio.Net 2003:
- Open DotZLib.sln in VS.Net and build from there. Output file (DotZLib.dll)
- will be found ./DotZLib/bin/release or ./DotZLib/bin/debug, depending on
- you are building the release or debug version of the library. Check
- DotZLib/UnitTests.cs for instructions on how to include unit tests in the
- build.
-
-2. Using NAnt:
- Open a command prompt with access to the build environment and run nant
- in the same directory as the DotZLib.build file.
- You can define 2 properties on the nant command-line to control the build:
- debug={true|false} to toggle between release/debug builds (default=true).
- nunit={true|false} to include or esclude unit tests (default=true).
- Also the target clean will remove binaries.
- Output file (DotZLib.dll) will be found in either ./DotZLib/bin/release
- or ./DotZLib/bin/debug, depending on whether you are building the release
- or debug version of the library.
-

* - * Copyright (C) 2003 Chris Anderson <christop@charm.net> - * Please use the copyright conditions above. - * - * This version (Jan-23-2003) of inflate_fast was coded and tested under - * GNU/Linux on a pentium 3, using the gcc-3.2 compiler distribution. On that - * machine, I found that gzip style archives decompressed about 20% faster than - * the gcc-3.2 -O3 -fomit-frame-pointer compiled version. Your results will - * depend on how large of a buffer is used for z_stream.next_in & next_out - * (8K-32K worked best for my 256K cpu cache) and how much overhead there is in - * stream processing I/O and crc32/addler32. In my case, this routine used - * 70% of the cpu time and crc32 used 20%. - * - * I am confident that this version will work in the general case, but I have - * not tested a wide variety of datasets or a wide variety of platforms. - * - * Jan-24-2003 -- Added -DUSE_MMX define for slightly faster inflating. - * It should be a runtime flag instead of compile time flag... - * - * Jan-26-2003 -- Added runtime check for MMX support with cpuid instruction. - * With -DUSE_MMX, only MMX code is compiled. With -DNO_MMX, only non-MMX code - * is compiled. Without either option, runtime detection is enabled. Runtime - * detection should work on all modern cpus and the recomended algorithm (flip - * ID bit on eflags and then use the cpuid instruction) is used in many - * multimedia applications. Tested under win2k with gcc-2.95 and gas-2.12 - * distributed with cygwin3. Compiling with gcc-2.95 -c inffast.S -o - * inffast.obj generates a COFF object which can then be linked with MSVC++ - * compiled code. Tested under FreeBSD 4.7 with gcc-2.95. - * - * Jan-28-2003 -- Tested Athlon XP... MMX mode is slower than no MMX (and - * slower than compiler generated code). Adjusted cpuid check to use the MMX - * code only for Pentiums < P4 until I have more data on the P4. Speed - * improvment is only about 15% on the Athlon when compared with code generated - * with MSVC++. Not sure yet, but I think the P4 will also be slower using the - * MMX mode because many of it's x86 ALU instructions execute in .5 cycles and - * have less latency than MMX ops. Added code to buffer the last 11 bytes of - * the input stream since the MMX code grabs bits in chunks of 32, which - * differs from the inffast.c algorithm. I don't think there would have been - * read overruns where a page boundary was crossed (a segfault), but there - * could have been overruns when next_in ends on unaligned memory (unintialized - * memory read). - * - * Mar-13-2003 -- P4 MMX is slightly slower than P4 NO_MMX. I created a C - * version of the non-MMX code so that it doesn't depend on zstrm and zstate - * structure offsets which are hard coded in this file. This was last tested - * with zlib-1.2.0 which is currently in beta testing, newer versions of this - * and inffas86.c can be found at http://www.eetbeetee.com/zlib/ and - * http://www.charm.net/~christop/zlib/ - */ - - -/* - * if you have underscore linking problems (_inflate_fast undefined), try - * using -DGAS_COFF - */ -#if ! defined( GAS_COFF ) && ! defined( GAS_ELF ) - -#if defined( WIN32 ) || defined( __CYGWIN__ ) -#define GAS_COFF /* windows object format */ -#else -#define GAS_ELF -#endif - -#endif /* !

- *
- * Dec-29-2003 -- I added AMD64 inflate asm support. This version is also
- * slightly quicker on x86 systems because, instead of using rep movsb to copy
- * data, it uses rep movsw, which moves data in 2-byte chunks instead of single
- * bytes. I've tested the AMD64 code on a Fedora Core 1 + the x86_64 updates
- * from http://fedora.linux.duke.edu/fc1_x86_64
- * which is running on an Athlon 64 3000+ / Gigabyte GA-K8VT800M system with

- * when decompressing mozilla-source-1.3.tar.gz.
- *
- * Mar-13-2003 -- Most of this is derived from inffast.S which is derived from
- * the gcc -S output of zlib-1.2.0/inffast.c. Zlib-1.2.0 is in beta release at
- * the moment. I have successfully compiled and tested this code with gcc2.96,
- * gcc3.2, icc5.0, msvc6.0. It is very close to the speed of inffast.S
- * compiled with gcc -DNO_MMX, but inffast.S is still faster on the P3 with MMX

-
-/*
- Decode literal, length, and distance codes and write out the resulting
- literal and match bytes until either not enough input or output is
- available, an end-of-block is encountered, or a data error is encountered.
- When large enough input and output buffers are supplied to inflate(), for
- example, a 16K input buffer and a 64K output buffer, more than 95% of the
- inflate execution time is spent in this routine.
-
- Entry assumptions:
-
- state->mode == LEN
- strm->avail_in >= 6
- strm->avail_out >= 258
- start >= strm->avail_out
- state->bits < 8
-
- On return, state->mode is one of:
-
- LEN -- ran out of enough output space or enough available input
- TYPE -- reached end of block code, inflate() to interpret next block
- BAD -- error in block data
-
- Notes:
-
- - The maximum input bits used by a length/distance pair is 15 bits for the
- length code, 5 bits for the length extra, 15 bits for the distance code,
- and 13 bits for the distance extra. This totals 48 bits, or six bytes.
- Therefore if strm->avail_in >= 6, then there is enough input to avoid
- checking for available input while decoding.
-
- - The maximum bytes that a single length/distance pair can output is 258
- bytes, which is the maximum length that can be coded. inflate_fast()
- requires strm->avail_out >= 258 for each loop to avoid checking for
- output space.

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 readabilty. 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.

This does not mean a zero-length code, but rather - * that no code should be created for this symbol. There is no way in the - * deflate format to represent a zero-length code. - * - * - The maximum number of bits in a code is 15, so the possible lengths for - * any code are 1..15. - * - * - The fact that a length of zero is not permitted for a code has an - * interesting consequence. Normally if only one symbol is used for a given - * code, then in fact that code could be represented with zero bits. However - * in deflate, that code has to be at least one bit. So for example, if - * only a single distance base symbol appears in a block, then it will be - * represented by a single code of length one, in particular one 0 bit. This - * is an incomplete code, since if a 1 bit is received, it has no meaning, - * and should result in an error. So incomplete distance codes of one symbol - * should be permitted, and the receipt of invalid codes should be handled. - * - * - It is also possible to have a single literal/length code, but that code - * must be the end-of-block code, since every dynamic block has one. This - * is not the most efficient way to create an empty block (an empty fixed - * block is fewer bits), but it is allowed by the format. So incomplete - * literal/length codes of one symbol should also be permitted. - * - * - If there are only literal codes and no lengths, then there are no distance - * codes. This is represented by one distance code with zero bits. - * - * - The list of up to 286 length/literal lengths and up to 30 distance lengths - * are themselves compressed using Huffman codes and run-length encoding. In - * the list of code lengths, a 0 symbol means no code, a 1..15 symbol means - * that length, and the symbols 16, 17, and 18 are run-length instructions. - * Each of 16, 17, and 18 are follwed by extra bits to define the length of - * the run. 16 copies the last length 3 to 6 times. 17 represents 3 to 10 - * zero lengths, and 18 represents 11 to 138 zero lengths. 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. The code length code lengths are received in a permuted order (see - * the order[] array below) to make a short code length code length list more - * likely. As it turns out, very short and very long codes are less likely - * to be seen in a dynamic code description, hence what may appear initially - * to be a peculiar ordering. - * - * - Given the number of literal/length code lengths (nlen) and distance code - * lengths (ndist), then they are treated as one long list of nlen + ndist - * code lengths. Therefore run-length coding can and often does cross the - * boundary between the two sets of lengths. - * - * - So to summarize, the code description at the start of a dynamic block is - * three counts for the number of code lengths for the literal/length codes, - * the distance codes, and the code length codes.

-=======================================================
-
-This directory contains projects that build zlib and minizip using
-Microsoft Visual C++ 7.0/7.1.
-
-You don't need to build these projects yourself. You can download the
-binaries from:
- http://www.winimage.com/zLibDll
-
-More information can be found at this site.
-
-
-Build instructions
-------------------
-- Unzip zlib*.zip and copy the files from contrib\vstudio\vc7,
- from contrib\vstudio\masmx86 and from contrib\minizip into the same
- directory.
-- Download the crtdll library from
- http://www.winimage.com/zLibDll/crtdll.zip
- Unzip crtdll.zip to extract crtdll.lib.
-- If you are using x86, use the Release target.
-- Open zlibvc.sln with Microsoft Visual C++ 7.0 or 7.1
- (Visual Studio .Net 2002 or 2003).
-
-
-Important
----------
-- To use zlibwapi.dll in your application, you must define the
- macro ZLIB_WINAPI when compiling your application's source files.
-
-
-Additional notes
-----------------
-- This DLL, named zlibwapi.dll, is compatible to the old zlib.dll built
- by Gilles Vollant from the zlib 1.1.x sources, and distributed at
- http://www.winimage.com/zLibDll
- It uses the WINAPI calling convention for the exported functions, and
- includes the minizip functionality. If your application needs that
- particular build of zlib.dll, you can rename zlibwapi.dll to zlib.dll.
-
-- The new DLL was renamed because there exist several incompatible
- versions of zlib.dll on the Internet.
-
-- There is also an official DLL build of zlib, named zlib1.dll. This one
- is exporting the functions using the CDECL convention. See the file
- win32\DLL_FAQ.txt found in this zlib distribution.
-
-- There used to be a ZLIB_DLL macro in zlib 1.1.x, but now this symbol
- has a slightly different effect. To avoid compatibility problems, do
- not define it here.

That will result in a - final compressed stream whose length is less than or equal to the - requested size. Assuming sufficient input and a requested size - greater than a few hundred bytes, the shortfall will typically be - less than ten bytes. - - If the input is short enough that the first compression completes - before filling the requested output size, then that compressed - stream is return with no recompression. - - EXCESS is chosen to be just greater than the shortfall seen in a - two pass approach similar to the above. That shortfall is due to - the last deflate block compressing more efficiently with a smaller - header on the second pass. EXCESS is set to be large enough so - that there is enough uncompressed data for the second pass to fill - out the requested size, and small enough so that the final deflate - block of the second pass will be close in size to the final deflate - block of the third and final pass. MARGIN is chosen to be just - large enough to assure that the final compression has enough room - to complete in all cases. - */ - -#include <stdio.h> -#include <stdlib.h> -#include <assert.h> -#include "zlib.h" - -#define local static - -/* print nastygram and leave */ -local void quit(char *why) -{ - fprintf(stderr, "fitblk abort: %s\n", why); - exit(1); -} - -#define RAWLEN 4096 /* intermediate uncompressed buffer size */ - -/* compress from file to def until provided buffer is full or end of - input reached; return last deflate() return value, or Z_ERRNO if - there was read error on the file */ -local int partcompress(FILE *in, z_streamp def) -{ - int ret, flush; - char raw[RAWLEN]; - - flush = Z_NO_FLUSH; - do { - def->avail_in = fread(raw, 1, RAWLEN, in); - if (ferror(in)) - return Z_ERRNO; - def->next_in = raw; - if (feof(in)) - flush = Z_FINISH; - ret = deflate(def, flush); - assert(ret != Z_STREAM_ERROR); - } while (def->avail_out != 0 && flush == Z_NO_FLUSH); - return ret; -} - -/* recompress from inf's input to def's output; the input for inf and - the output for def are set in those structures before calling; - return last deflate() return value, or Z_MEM_ERROR if inflate() - was not able to allocate enough memory when it needed to */ -local int recompress(z_streamp inf, z_streamp def) -{ - int ret, flush; - char raw[RAWLEN]; - - flush = Z_NO_FLUSH; - do { - /* decompress */ - inf->avail_out = RAWLEN; - inf->next_out = raw; - ret = inflate(inf, Z_NO_FLUSH); - assert(ret != Z_STREAM_ERROR && ret != Z_DATA_ERROR && - ret != Z_NEED_DICT); - if (ret == Z_MEM_ERROR) - return ret; - - /* compress what was decompresed until done or no room */ - def->avail_in = RAWLEN - inf->avail_out; - def->next_in = raw; - if (inf->avail_out != 0) - flush = Z_FINISH; - ret = deflate(def, flush); - assert(ret != Z_STREAM_ERROR); - } while (ret != Z_STREAM_END && def->avail_out != 0); - return ret; -} - -#define EXCESS 256 /* empirically determined stream overage */ -#define MARGIN 8 /* amount to back off for completion */ - -/* compress from stdin to fixed-size block on stdout */ -int main(int argc, char **argv) -{ - int ret; /* return code */ - unsigned size; /* requested fixed output block size */ - unsigned have; /* bytes written by deflate() call */ - char *blk; /* intermediate and final stream */ - char *tmp; /* close to desired size stream */ - z_stream def, inf; /* zlib deflate and inflate states */ - - /* get requested output size */ - if (argc != 2) - quit("need one argument: size of output block"); - ret = strtol(argv[1], argv + 1, 10); - if (argv[1][0] != 0) - quit("argument must be a number"); - if (ret < 8) /* 8 is minimum zlib stream size */ - quit("need positive size of 8 or greater"); - size = (unsigned)ret; - - /* allocate memory for buffers and compression engine */ - blk = malloc(size + EXCESS); - def.zalloc = Z_NULL; - def.zfree = Z_NULL; - def.opaque = Z_NULL; - ret = deflateInit(&def, Z_DEFAULT_COMPRESSION); - if (ret != Z_OK || blk == NULL) - quit("out of memory"); - - /* compress from stdin until output full, or no more input */ - def.avail_out = size + EXCESS; - def.next_out = blk; - ret = partcompress(stdin, &def); - if (ret == Z_ERRNO) - quit("error reading input"); - - /* if it all fit, then size was undersubscribed -- done!

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 unusued 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 <stdio.h> -#include <stdlib.h> -#include <string.h> -#include <fcntl.h> -#include <unistd.h> -#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);

The output gzip file - has a minimal ten-byte gzip header with no file name or modification time. - - This program was written to illustrate the use of the Z_BLOCK option of - inflate() and the crc32_combine() function. gzjoin will not compile with - versions of zlib earlier than 1.2.3. - */ - -#include <stdio.h> /* fputs(), fprintf(), fwrite(), putc() */ -#include <stdlib.h> /* exit(), malloc(), free() */ -#include <fcntl.h> /* open() */ -#include <unistd.h> /* close(), read(), lseek() */ -#include "zlib.h" - /* crc32(), crc32_combine(), inflateInit2(), inflate(), inflateEnd() */ - -#define local static - -/* exit with an error (return a value to allow use in an expression) */ -local int bail(char *why1, char *why2) -{ - fprintf(stderr, "gzjoin error: %s%s, output incomplete\n", why1, why2); - exit(1); - return 0; -} - -/* -- simple buffered file input with access to the buffer -- */ - -#define CHUNK 32768 /* must be a power of two and fit in unsigned */ - -/* bin buffered input file type */ -typedef struct { - char *name; /* name of file for error messages */ - int fd; /* file descriptor */ - unsigned left; /* bytes remaining at next */ - unsigned char *next; /* next byte to read */ - unsigned char *buf; /* allocated buffer of length CHUNK */ -} bin; - -/* close a buffered file and free allocated memory */ -local void bclose(bin *in) -{ - if (in != NULL) { - if (in->fd != -1) - close(in->fd); - if (in->buf != NULL) - free(in->buf); - free(in); - } -} - -/* open a buffered file for input, return a pointer to type bin, or NULL on - failure */ -local bin *bopen(char *name) -{ - bin *in; - - in = malloc(sizeof(bin)); - if (in == NULL) - return NULL; - in->buf = malloc(CHUNK); - in->fd = open(name, O_RDONLY, 0); - if (in->buf == NULL || in->fd == -1) { - bclose(in); - return NULL; - } - in->left = 0; - in->next = in->buf; - in->name = name; - return in; -} - -/* load buffer from file, return -1 on read error, 0 or 1 on success, with - 1 indicating that end-of-file was reached */ -local int bload(bin *in) -{ - ssize_t len; - - if (in == NULL) - return -1; - if (in->left != 0) - return 0; - in->next = in->buf; - do { - len = read(in->fd, in->buf + in->left, CHUNK - in->left); - if (len < 0) - return -1; - in->left += (unsigned)len; - } while (len != 0 && in->left < CHUNK); - return len == 0 ? 1 : 0; -} - -/* get a byte from the file, bail if end of file */ -#define bget(in) (in->left ? 0 : bload(in), \ - in->left ?

The - strategy is to write the short strings in an uncompressed form to the end of - the gzip file, only compressing when the amount of uncompressed data has - reached a given threshold. - - gzlog also provides protection against interruptions in the process due to - system crashes. The status of the operation is recorded in an extra field - in the gzip file, and is only updated once the gzip file is brought to a - valid state. The last data to be appended or compressed is saved in an - auxiliary file, so that if the operation is interrupted, it can be completed - the next time an append operation is attempted. - - gzlog maintains another auxiliary file with the last 32K of data from the - compressed portion, which is preloaded for the compression of the subsequent - data. 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.

Why -not? Well, it turns out that <tt>deflate()</tt> can do no wrong here. Let's go through -<tt>deflate()</tt>'s return values and dispense with them one by one.

This is already guaranteed by calling <tt>deflate()</tt> with <tt>Z_FINISH</tt> -until it has no more output. <tt>Z_STREAM_ERROR</tt> is only possible if the stream is not -initialized properly, but we did initialize it properly. There is no harm in checking for -<tt>Z_STREAM_ERROR</tt> here, for example to check for the possibility that some -other part of the application inadvertently clobbered the memory containing the <em>zlib</em> state. -<tt>Z_BUF_ERROR</tt> will be explained further below, but -suffice it to say that this is simply an indication that <tt>deflate()</tt> could not consume -more input or produce more output. <tt>deflate()</tt> can be called again with more output space -or more available input, which it will be in this code. -<pre><b> - ret = deflate(&strm, flush); /* no bad return value */ - assert(ret != Z_STREAM_ERROR); /* state not clobbered */ -</b></pre> -Now we compute how much output <tt>deflate()</tt> 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 <tt>deflate()</tt>.

Then we know that <tt>deflate()</tt> 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. -<p> -The way we tell that <tt>deflate()</tt> has no more output is by seeing that it did not fill -the output buffer, leaving <tt>avail_out</tt> greater than zero.

This -is because the application has the option to provide the start of the zlib stream in -order for <tt>inflateInit()</tt> to have access to information about the compression -method to aid in memory allocation. In the current implementation of <em>zlib</em> -(up through versions 1.2.x), the method-dependent memory allocations are deferred to the first call of -<tt>inflate()</tt> anyway.

This version of the library supports only one compression method - (deflation) but other algorithms will be added later and will have the same - stream interface. - <p> - - Compression can be done in a single step if the buffers are large - enough (for example if an input file is mmap'ed), or can be done by - repeated calls of the compression function. In the latter case, the - application must provide more input and/or consume the output - (providing more output space) before each call. - <p> - - The library also supports reading and writing files in gzip (.gz) format - with an interface similar to that of stdio. - <p> - - The library does not install any signal handler. The decoder checks - the consistency of the compressed data, so the library should never - crash even in case of corrupted input. - <p> - -<hr> -<a name="Utility functions"><h2> Utility functions </h2> - The following utility functions are implemented on top of the - <a href="#Basic functions">basic stream-oriented functions</a>. - To simplify the interface, some - default options are assumed (compression level and memory usage, - standard memory allocation functions). The source code of these - utility functions can easily be modified if you need special options. -<h3> Function list </h3> -<ul> -<li> int <a href="#compress">compress</a> (Bytef *dest, uLongf *destLen, const Bytef *source, uLong sourceLen); -<li> int <a href="#compress2">compress2</a> (Bytef *dest, uLongf *destLen, const Bytef *source, uLong sourceLen, int level); -<li> int <a href="#uncompress">uncompress</a> (Bytef *dest, uLongf *destLen, const Bytef *source, uLong sourceLen); -<li> typedef voidp gzFile; -<li> gzFile <a href="#gzopen">gzopen</a> (const char *path, const char *mode); -<li> gzFile <a href="#gzdopen">gzdopen</a> (int fd, const char *mode); -<li> int <a href="#gzsetparams">gzsetparams</a> (gzFile file, int level, int strategy); -<li> int <a href="#gzread">gzread</a> (gzFile file, voidp buf, unsigned len); -<li> int <a href="#gzwrite">gzwrite</a> (gzFile file, const voidp buf, unsigned len); -<li> int VA <a href="#gzprintf">gzprintf</a> (gzFile file, const char *format, ...); -<li> int <a href="#gzputs">gzputs</a> (gzFile file, const char *s); -<li> char * <a href="#gzgets">gzgets</a> (gzFile file, char *buf, int len); -<li> int <a href="#gzputc">gzputc</a> (gzFile file, int c); -<li> int <a href="#gzgetc">gzgetc</a> (gzFile file); -<li> int <a href="#gzflush">gzflush</a> (gzFile file, int flush); -<li> z_off_t <a href="#gzseek">gzseek</a> (gzFile file, z_off_t offset, int whence); -<li> z_off_t <a href="#gztell">gztell</a> (gzFile file); -<li> int <a href="#gzrewind">gzrewind</a> (gzFile file); -<li> int <a href="#gzeof">gzeof</a> (gzFile file); -<li> int <a href="#gzclose">gzclose</a> (gzFile file); -<li> const char * <a href="#gzerror">gzerror</a> (gzFile file, int *errnum); -</ul> -<h3> Function description </h3> -<dl> -<font color="Blue"><dt> int <a name="compress">compress</a> (Bytef *dest, uLongf *destLen, const Bytef *source, uLong sourceLen);</font> -<dd> - Compresses the source buffer into the destination buffer. sourceLen is - the byte length of the source buffer.

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 <windows.h>, 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 - <windows.h> 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 - <<my favorite C run-time library>> ? - - - 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. If you need something peculiar from this DLL, you - can send your suggestion to the zlib mailing list. - - However, in case you do rebuild the DLL yourself, you can run - it with the test programs found in the DLL distribution. - Running these test programs is not a guarantee of compliance, - but a failure can imply a detected problem. - -** - -This document is written and maintained by -Cosmin Truta <cosmint@cs.ubbcluj.ro> diff --git a/cpukit/zlib/win32/Makefile.bor b/cpukit/zlib/win32/Makefile.bor deleted file mode 100644 index 3981d4246b..0000000000 --- a/cpukit/zlib/win32/Makefile.bor +++ /dev/null @@ -1,110 +0,0 @@ -# Makefile for zlib -# Borland C++ for Win32 -# -# Usage: -# make -f win32/Makefile.bor -# make -f win32/Makefile.bor LOCAL_ZLIB=-DASMV OBJA=match.obj OBJPA=+match.obj - -# ------------ Borland C++ ------------ - -# Optional nonstandard preprocessor flags (e.g. -DMAX_MEM_LEVEL=7) -# should be added to the environment via "set LOCAL_ZLIB=-DFOO" or -# added to the declaration of LOC here: -LOC = $(LOCAL_ZLIB) - -CC = bcc32 -AS = bcc32 -LD = bcc32 -AR = tlib -CFLAGS = -a -d -k- -O2 $(LOC) -ASFLAGS = $(LOC) -LDFLAGS = $(LOC) - - -# variables -ZLIB_LIB = zlib.lib - -OBJ1 = adler32.obj compress.obj crc32.obj deflate.obj gzclose.obj gzlib.obj gzread.obj -OBJ2 = gzwrite.obj infback.obj inffast.obj inflate.obj inftrees.obj trees.obj uncompr.obj zutil.obj -#OBJA = -OBJP1 = +adler32.obj+compress.obj+crc32.obj+deflate.obj+gzclose.obj+gzlib.obj+gzread.obj -OBJP2 = +gzwrite.obj+infback.obj+inffast.obj+inflate.obj+inftrees.obj+trees.obj+uncompr.obj+zutil.obj -#OBJPA= - - -# targets -all: $(ZLIB_LIB) example.exe minigzip.exe - -.c.obj: - $(CC) -c $(CFLAGS) $< - -.asm.obj: - $(AS) -c $(ASFLAGS) $< - -adler32.obj: adler32.c zlib.h zconf.h - -compress.obj: compress.c zlib.h zconf.h - -crc32.obj: crc32.c zlib.h zconf.h crc32.h - -deflate.obj: deflate.c deflate.h zutil.h zlib.h zconf.h - -gzclose.obj: gzclose.c zlib.h zconf.h gzguts.h - -gzlib.obj: gzlib.c zlib.h zconf.h gzguts.h - -gzread.obj: gzread.c zlib.h zconf.h gzguts.h - -gzwrite.obj: gzwrite.c zlib.h zconf.h gzguts.h - -infback.obj: infback.c zutil.h zlib.h zconf.h inftrees.h inflate.h \ - inffast.h inffixed.h - -inffast.obj: inffast.c zutil.h zlib.h zconf.h inftrees.h inflate.h \ - inffast.h - -inflate.obj: inflate.c zutil.h zlib.h zconf.h inftrees.h inflate.h \ - inffast.h inffixed.h - -inftrees.obj: inftrees.c zutil.h zlib.h zconf.h inftrees.h - -trees.obj: trees.c zutil.h zlib.h zconf.h deflate.h trees.h - -uncompr.obj: uncompr.c zlib.h zconf.h - -zutil.obj: zutil.c zutil.h zlib.h zconf.h - -example.obj: example.c zlib.h zconf.h - -minigzip.obj: minigzip.c zlib.h zconf.h - - -# For the sake of the old Borland make, -# the command line is cut to fit in the MS-DOS 128 byte limit: -$(ZLIB_LIB): $(OBJ1) $(OBJ2) $(OBJA) - -del $(ZLIB_LIB) - $(AR) $(ZLIB_LIB) $(OBJP1) - $(AR) $(ZLIB_LIB) $(OBJP2) - $(AR) $(ZLIB_LIB) $(OBJPA) - - -# testing -test: example.exe minigzip.exe - example - echo hello world | minigzip | minigzip -d - -example.exe: example.obj $(ZLIB_LIB) - $(LD) $(LDFLAGS) example.obj $(ZLIB_LIB) - -minigzip.exe: minigzip.obj $(ZLIB_LIB) - $(LD) $(LDFLAGS) minigzip.obj $(ZLIB_LIB) - - -# cleanup -clean: - -del $(ZLIB_LIB) - -del *.obj - -del *.exe - -del *.tds - -del zlib.bak - -del foo.gz diff --git a/cpukit/zlib/win32/Makefile.emx b/cpukit/zlib/win32/Makefile.emx deleted file mode 100644 index 4d6ab0efa6..0000000000 --- a/cpukit/zlib/win32/Makefile.emx +++ /dev/null @@ -1,69 +0,0 @@ -# Makefile for zlib.
