| 2 | ChangeLog file for zlib | |
| 3 | ||
| 4 | Changes in 1.1.2 (19 March 98) | |
| 5 | - added contrib/minzip, mini zip and unzip based on zlib (Gilles Vollant) | |
| 6 | See http://www.winimage.com/zLibDll/unzip.html | |
| 7 | - preinitialize the inflate tables for fixed codes, to make the code | |
| 8 | completely thread safe (Mark) | |
| 9 | - some simplifications and slight speed-up to the inflate code (Mark) | |
| 10 | - fix gzeof on non-compressed files (Allan Schrum) | |
| 11 | - add -std1 option in configure for OSF1 to fix gzprintf (Martin Mokrejs) | |
| 12 | - use default value of 4K for Z_BUFSIZE for 16-bit MSDOS (Tim Wegner + Glenn) | |
| 13 | - added os2/Makefile.def and os2/zlib.def (Andrew Zabolotny) | |
| 14 | - add shared lib support for UNIX_SV4.2MP (MATSUURA Takanori) | |
| 15 | - do not wrap extern "C" around system includes (Tom Lane) | |
| 16 | - mention zlib binding for TCL in README (Andreas Kupries) | |
| 17 | - added amiga/Makefile.pup for Amiga powerUP SAS/C PPC (Andreas Kleinert) | |
| 18 | - allow "make install prefix=..." even after configure (Glenn Randers-Pehrson) | |
| 19 | - allow "configure --prefix $HOME" (Tim Mooney) | |
| 20 | - remove warnings in example.c and gzio.c (Glenn Randers-Pehrson) | |
| 21 | - move Makefile.sas to amiga/Makefile.sas | |
| 22 | ||
| 23 | Changes in 1.1.1 (27 Feb 98) | |
| 24 | - fix macros _tr_tally_* in deflate.h for debug mode (Glenn Randers-Pehrson) | |
| 25 | - remove block truncation heuristic which had very marginal effect for zlib | |
| 26 | (smaller lit_bufsize than in gzip 1.2.4) and degraded a little the | |
| 27 | compression ratio on some files. This also allows inlining _tr_tally for | |
| 28 | matches in deflate_slow. | |
| 29 | - added msdos/Makefile.w32 for WIN32 Microsoft Visual C++ (Bob Frazier) | |
| 30 | ||
| 31 | Changes in 1.1.0 (24 Feb 98) | |
| 32 | - do not return STREAM_END prematurely in inflate (John Bowler) | |
| 33 | - revert to the zlib 1.0.8 inflate to avoid the gcc 2.8.0 bug (Jeremy Buhler) | |
| 34 | - compile with -DFASTEST to get compression code optimized for speed only | |
| 35 | - in minigzip, try mmap'ing the input file first (Miguel Albrecht) | |
| 36 | - increase size of I/O buffers in minigzip.c and gzio.c (not a big gain | |
| 37 | on Sun but significant on HP) | |
| 38 | ||
| 39 | - add a pointer to experimental unzip library in README (Gilles Vollant) | |
| 40 | - initialize variable gcc in configure (Chris Herborth) | |
| 41 | ||
| 42 | Changes in 1.0.9 (17 Feb 1998) | |
| 43 | - added gzputs and gzgets functions | |
| 44 | - do not clear eof flag in gzseek (Mark Diekhans) | |
| 45 | - fix gzseek for files in transparent mode (Mark Diekhans) | |
| 46 | - do not assume that vsprintf returns the number of bytes written (Jens Krinke) | |
| 47 | - replace EXPORT with ZEXPORT to avoid conflict with other programs | |
| 48 | - added compress2 in zconf.h, zlib.def, zlib.dnt | |
| 49 | - new asm code from Gilles Vollant in contrib/asm386 | |
| 50 | - simplify the inflate code (Mark): | |
| 51 | . Replace ZALLOC's in huft_build() with single ZALLOC in inflate_blocks_new() | |
| 52 | . ZALLOC the length list in inflate_trees_fixed() instead of using stack | |
| 53 | . ZALLOC the value area for huft_build() instead of using stack | |
| 54 | . Simplify Z_FINISH check in inflate() | |
| 55 | ||

| 57 | - in inftrees.c, avoid cc -O bug on HP (Farshid Elahi) | |
| 58 | - in zconf.h move the ZLIB_DLL stuff earlier to avoid problems with | |
| 59 | the declaration of FAR (Gilles VOllant) | |
| 60 | - install libz.so* with mode 755 (executable) instead of 644 (Marc Lehmann) | |
| 61 | - read_buf buf parameter of type Bytef* instead of charf* | |
| 62 | - zmemcpy parameters are of type Bytef*, not charf* (Joseph Strout) | |
| 63 | - do not redeclare unlink in minigzip.c for WIN32 (John Bowler) | |
| 64 | - fix check for presence of directories in "make install" (Ian Willis) | |
| 65 | ||
| 66 | Changes in 1.0.8 (27 Jan 1998) | |
| 67 | - fixed offsets in contrib/asm386/gvmat32.asm (Gilles Vollant) | |
| 68 | - fix gzgetc and gzputc for big endian systems (Markus Oberhumer) | |
| 69 | - added compress2() to allow setting the compression level | |
| 70 | - include sys/types.h to get off_t on some systems (Marc Lehmann & QingLong) | |
| 71 | - use constant arrays for the static trees in trees.c instead of computing | |
| 72 | them at run time (thanks to Ken Raeburn for this suggestion). To create | |
| 73 | trees.h, compile with GEN_TREES_H and run "make test". | |
| 74 | - check return code of example in "make test" and display result | |
| 75 | - pass minigzip command line options to file_compress | |
| 76 | - simplifying code of inflateSync to avoid gcc 2.8 bug | |

| 85 | - avoid warnings in gzio.c and deflate.c (Andreas Kleinert) | |
| 86 | - use const for the CRC table (Ken Raeburn) | |
| 87 | - fixed "make uninstall" for shared libraries | |
| 88 | - use Tracev instead of Trace in infblock.c | |
| 89 | - in example.c use correct compressed length for test_sync | |

| 110 | gzsetparams (thanks to Roland Giersig and Kevin Ruland for some of this code) | |
| 111 | - Fix a deflate bug occuring only with compression level 0 (thanks to | |
| 112 | Andy Buckler for finding this one). | |
| 113 | - In minigzip, pass transparently also the first byte for .Z files. | |
| 114 | - return Z_BUF_ERROR instead of Z_OK if output buffer full in uncompress() | |
| 115 | - check Z_FINISH in inflate (thanks to Marc Schluper) | |
| 116 | - Implement deflateCopy (thanks to Adam Costello) | |
| 117 | - make static libraries by default in configure, add --shared option. | |
| 118 | - move MSDOS or Windows specific files to directory msdos | |
| 119 | - suppress the notion of partial flush to simplify the interface | |
| 120 | (but the symbol Z_PARTIAL_FLUSH is kept for compatibility with 1.0.4) | |

| 122 | (this feature was not implemented anyway in 1.0.4) | |
| 123 | - next_in and avail_in must be initialized before calling inflateInit or | |
| 124 | inflateInit2 | |

| 127 | - added the unsupported "contrib" directory: | |
| 128 | contrib/asm386/ by Gilles Vollant <info@winimage.com> | |
| 129 | 386 asm code replacing longest_match(). | |
| 130 | contrib/iostream/ by Kevin Ruland <kevin@rodin.wustl.edu> | |
| 131 | A C++ I/O streams interface to the zlib gz* functions | |
