- put the crc table in FAR data (I dislike more and more the medium model :) | |
- added get_crc_table | |
- added a dimension to all arrays (Borland C can't count). | |
- workaround Borland C bug in declaration of inflate_codes_new & inflate_fast | |
- guard against multiple inclusion of *.h (for precompiled header on Mac) | |
- Watcom C pretends to be Microsoft C small model even in 32 bit mode. | |
- don't use unsized arrays to avoid silly warnings by Visual C++: | |
warning C4746: 'inflate_mask' : unsized array treated as '__far' | |
(what's wrong with far data in far model?). | |
- define enum out of inflate_blocks_state to allow compilation with C++ | |
Changes in 0.95 (16 Aug 95) | |
- fix MSDOS small and medium model (now easier to adapt to any compiler) | |
- inlined send_bits | |
- fix the final (:-) bug for deflate with flush (output was correct but | |
not completely flushed in rare occasions). | |
- default window size is same for compression and decompression | |
(it's now sufficient to set MAX_WBITS in zconf.h). | |
- voidp -> voidpf and voidnp -> voidp (for consistency with other | |
typedefs and because voidnp was not near in large model). | |
Changes in 0.94 (13 Aug 95) | |
- support MSDOS medium model | |
- fix deflate with flush (could sometimes generate bad output) | |
- fix deflateReset (zlib header was incorrectly suppressed) | |
- added support for VMS | |
- allow a compression level in gzopen() | |
- gzflush now calls fflush | |
- For deflate with flush, flush even if no more input is provided. | |
- rename libgz.a as libz.a | |
- avoid complex expression in infcodes.c triggering Turbo C bug | |
- work around a problem with gcc on Alpha (in INSERT_STRING) | |
- don't use inline functions (problem with some gcc versions) | |
- allow renaming of Byte, uInt, etc... with #define. | |
- avoid warning about (unused) pointer before start of array in deflate.c | |
- avoid various warnings in gzio.c, example.c, infblock.c, adler32.c, zutil.c | |
- avoid reserved word 'new' in trees.c | |
Changes in 0.93 (25 June 95) | |
- temporarily disable inline functions | |
- make deflate deterministic | |
- give enough lookahead for PARTIAL_FLUSH | |
- Set binary mode for stdin/stdout in minigzip.c for OS/2 | |
- don't even use signed char in inflate (not portable enough) | |
- fix inflate memory leak for segmented architectures | |
Changes in 0.92 (3 May 95) | |
- don't assume that char is signed (problem on SGI) | |
- Clear bit buffer when starting a stored block | |
- no memcpy on Pyramid | |
- suppressed inftest.c | |
- optimized fill_window, put longest_match inline for gcc | |
- optimized inflate on stored blocks. | |
- untabify all sources to simplify patches | |
Changes in 0.91 (2 May 95) | |
- Default MEM_LEVEL is 8 (not 9 for Unix) as documented in zlib.h | |
- Document the memory requirements in zconf.h | |
- added "make install" | |
- fix sync search logic in inflateSync | |
- deflate(Z_FULL_FLUSH) now works even if output buffer too short | |
- after inflateSync, don't scare people with just "lo world" | |
- added support for DJGPP | |
Changes in 0.9 (1 May 95) | |
- don't assume that zalloc clears the allocated memory (the TurboC bug | |
was Mark's bug after all :) | |
- let again gzread copy uncompressed data unchanged (was working in 0.71) | |
- deflate(Z_FULL_FLUSH), inflateReset and inflateSync are now fully implemented | |
- added a test of inflateSync in example.c | |
- moved MAX_WBITS to zconf.h because users might want to change that. | |
- document explicitly that zalloc(64K) on MSDOS must return a normalized | |
pointer (zero offset) | |
- added Makefiles for Microsoft C, Turbo C, Borland C++ | |
- faster crc32() | |
Changes in 0.8 (29 April 95) | |
- added fast inflate (inffast.c) | |
- deflate(Z_FINISH) now returns Z_STREAM_END when done. Warning: this | |
is incompatible with previous versions of zlib which returned Z_OK. | |
- work around a TurboC compiler bug (bad code for b << 0, see infutil.h) | |
(actually that was not a compiler bug, see 0.81 above) | |
- gzread no longer reads one extra byte in certain cases | |
- In gzio destroy(), don't reference a freed structure | |
- avoid many warnings for MSDOS | |
- avoid the ERROR symbol which is used by MS Windows | |
Changes in 0.71 (14 April 95) | |
- Fixed more MSDOS compilation problems :( There is still a bug with | |
TurboC large model. | |
Changes in 0.7 (14 April 95) | |
- Added full inflate support. | |
- Simplified the crc32() interface. The pre- and post-conditioning | |
(one's complement) is now done inside crc32(). WARNING: this is | |
incompatible with previous versions; see zlib.h for the new usage. | |
Changes in 0.61 (12 April 95) | |
- workaround for a bug in TurboC. example and minigzip now work on MSDOS. | |
Changes in 0.6 (11 April 95) | |
- added minigzip.c | |
- added gzdopen to reopen a file descriptor as gzFile | |
- added transparent reading of non-gziped files in gzread. | |
- fixed bug in gzread (don't read crc as data) | |
- fixed bug in destroy (gzio.c) (don't return Z_STREAM_END for gzclose). | |
- don't allocate big arrays in the stack (for MSDOS) | |
- fix some MSDOS compilation problems | |
Changes in 0.5: | |
- do real compression in deflate.c. Z_PARTIAL_FLUSH is supported but | |
not yet Z_FULL_FLUSH. | |
- support decompression but only in a single step (forced Z_FINISH) | |
- added opaque object for zalloc and zfree. | |
- added deflateReset and inflateReset | |
- added a variable zlib_version for consistency checking. | |
- renamed the 'filter' parameter of deflateInit2 as 'strategy'. | |
Added Z_FILTERED and Z_HUFFMAN_ONLY constants. | |
Changes in 0.4: | |
- avoid "zip" everywhere, use zlib instead of ziplib. | |
- suppress Z_BLOCK_FLUSH, interpret Z_PARTIAL_FLUSH as block flush | |
if compression method == 8. | |
- added adler32 and crc32 | |
- renamed deflateOptions as deflateInit2, call one or the other but not both | |
- added the method parameter for deflateInit2. | |
- added inflateInit2 | |
- simplied considerably deflateInit and inflateInit by not supporting | |
user-provided history buffer. This is supported only in deflateInit2 | |
and inflateInit2. | |
Changes in 0.3: | |
- prefix all macro names with Z_ | |
- use Z_FINISH instead of deflateEnd to finish compression. | |
- added Z_HUFFMAN_ONLY | |
- added gzerror() |
