621 | - In very rare conditions, deflate(s, Z_FINISH) could fail to produce an EOF | ||
622 | bit, so the decompressor could decompress all the correct data but went | ||
623 | on to attempt decompressing extra garbage data. This affected minigzip too. | ||

701 | - include errno.h for Cray | ||
702 | - ignore error if ranlib doesn't exist | ||
703 | - call ranlib twice for NeXTSTEP | ||
704 | - use exec_prefix instead of prefix for libz.a | ||
705 | - renamed ct_* as _tr_* to avoid conflict with applications | ||
706 | - clear z->msg in inflateInit2 before any error return | ||
707 | - initialize opaque in example.c, gzio.c, deflate.c and inflate.c | ||
708 | - fixed typo in zconf.h (_GNUC__ => __GNUC__) | ||
709 | - check for WIN32 in zconf.h and zutil.c (avoid farmalloc in 32-bit mode) | ||
710 | - fix typo in Make_vms.com (f$trnlnm -> f$getsyi) | ||
711 | - in fcalloc, normalize pointer if size > 65520 bytes | ||
712 | - don't use special fcalloc for 32 bit Borland C++ | ||
713 | - use STDC instead of __GO32__ to avoid redeclaring exit, calloc, etc... | ||
714 | - use Z_BINARY instead of BINARY | ||
715 | - document that gzclose after gzdopen will close the file | ||
716 | - allow "a" as mode in gzopen. | ||
717 | - fix error checking in gzread | ||
718 | - allow skipping .gz extra-field on pipes | ||
719 | - added reference to Perl interface in README | ||
720 | - put the crc table in FAR data (I dislike more and more the medium model :) | ||
721 | - added get_crc_table | ||
722 | - added a dimension to all arrays (Borland C can't count). | ||
723 | - workaround Borland C bug in declaration of inflate_codes_new & inflate_fast | ||
724 | - guard against multiple inclusion of *.h (for precompiled header on Mac) | ||
725 | - Watcom C pretends to be Microsoft C small model even in 32 bit mode. | ||
726 | - don't use unsized arrays to avoid silly warnings by Visual C++: | ||
727 | warning C4746: 'inflate_mask' : unsized array treated as '__far' | ||
728 | (what's wrong with far data in far model?). | ||
729 | - define enum out of inflate_blocks_state to allow compilation with C++ | ||
730 | |||
731 | Changes in 0.95 (16 Aug 95) | ||
732 | - fix MSDOS small and medium model (now easier to adapt to any compiler) | ||
733 | - inlined send_bits | ||
734 | - fix the final (:-) bug for deflate with flush (output was correct but | ||
735 | not completely flushed in rare occasions). | ||
736 | - default window size is same for compression and decompression | ||
737 | (it's now sufficient to set MAX_WBITS in zconf.h). | ||
738 | - voidp -> voidpf and voidnp -> voidp (for consistency with other | ||
739 | typedefs and because voidnp was not near in large model). | ||
740 | |||
741 | Changes in 0.94 (13 Aug 95) | ||
742 | - support MSDOS medium model | ||
743 | - fix deflate with flush (could sometimes generate bad output) | ||
744 | - fix deflateReset (zlib header was incorrectly suppressed) | ||
745 | - added support for VMS | ||
746 | - allow a compression level in gzopen() | ||
747 | - gzflush now calls fflush | ||
748 | - For deflate with flush, flush even if no more input is provided. | ||
749 | - rename libgz.a as libz.a | ||
750 | - avoid complex expression in infcodes.c triggering Turbo C bug | ||
751 | - work around a problem with gcc on Alpha (in INSERT_STRING) | ||
752 | - don't use inline functions (problem with some gcc versions) | ||
753 | - allow renaming of Byte, uInt, etc... with #define. | ||
754 | - avoid warning about (unused) pointer before start of array in deflate.c | ||
755 | - avoid various warnings in gzio.c, example.c, infblock.c, adler32.c, zutil.c | ||
756 | - avoid reserved word 'new' in trees.c | ||
757 | |||
758 | Changes in 0.93 (25 June 95) | ||
759 | - temporarily disable inline functions | ||
760 | - make deflate deterministic | ||
761 | - give enough lookahead for PARTIAL_FLUSH | ||
762 | - Set binary mode for stdin/stdout in minigzip.c for OS/2 | ||
763 | - don't even use signed char in inflate (not portable enough) | ||
764 | - fix inflate memory leak for segmented architectures | ||
765 | |||
766 | Changes in 0.92 (3 May 95) | ||
767 | - don't assume that char is signed (problem on SGI) | ||
768 | - Clear bit buffer when starting a stored block | ||
769 | - no memcpy on Pyramid | ||
770 | - suppressed inftest.c | ||
771 | - optimized fill_window, put longest_match inline for gcc | ||
772 | - optimized inflate on stored blocks. | ||
773 | - untabify all sources to simplify patches | ||
774 | |||
775 | Changes in 0.91 (2 May 95) | ||
776 | - Default MEM_LEVEL is 8 (not 9 for Unix) as documented in zlib.h | ||
777 | - Document the memory requirements in zconf.h | ||
778 | - added "make install" | ||
779 | - fix sync search logic in inflateSync | ||
780 | - deflate(Z_FULL_FLUSH) now works even if output buffer too short | ||
781 | - after inflateSync, don't scare people with just "lo world" | ||
782 | - added support for DJGPP | ||
783 | |||
784 | Changes in 0.9 (1 May 95) | ||
785 | - don't assume that zalloc clears the allocated memory (the TurboC bug | ||
786 | was Mark's bug after all :) | ||
787 | - let again gzread copy uncompressed data unchanged (was working in 0.71) | ||
788 | - deflate(Z_FULL_FLUSH), inflateReset and inflateSync are now fully implemented | ||
789 | - added a test of inflateSync in example.c | ||
790 | - moved MAX_WBITS to zconf.h because users might want to change that. | ||
791 | - document explicitly that zalloc(64K) on MSDOS must return a normalized | ||
792 | pointer (zero offset) | ||
793 | - added Makefiles for Microsoft C, Turbo C, Borland C++ | ||
794 | - faster crc32() | ||
795 | |||
796 | Changes in 0.8 (29 April 95) | ||
797 | - added fast inflate (inffast.c) | ||
798 | - deflate(Z_FINISH) now returns Z_STREAM_END when done. Warning: this | ||
799 | is incompatible with previous versions of zlib which returned Z_OK. | ||
800 | - work around a TurboC compiler bug (bad code for b << 0, see infutil.h) | ||
801 | (actually that was not a compiler bug, see 0.81 above) | ||
802 | - gzread no longer reads one extra byte in certain cases | ||
803 | - In gzio destroy(), don't reference a freed structure | ||
804 | - avoid many warnings for MSDOS | ||
805 | - avoid the ERROR symbol which is used by MS Windows | ||
806 | |||
807 | Changes in 0.71 (14 April 95) | ||
808 | - Fixed more MSDOS compilation problems :( There is still a bug with | ||
809 | TurboC large model. | ||
810 | |||
811 | Changes in 0.7 (14 April 95) | ||
812 | - Added full inflate support. | ||
813 | - Simplified the crc32() interface. The pre- and post-conditioning | ||
814 | (one's complement) is now done inside crc32(). WARNING: this is | ||
815 | incompatible with previous versions; see zlib.h for the new usage. | ||
816 | |||
817 | Changes in 0.61 (12 April 95) | ||
818 | - workaround for a bug in TurboC. example and minigzip now work on MSDOS. | ||
819 | |||
820 | Changes in 0.6 (11 April 95) | ||
821 | - added minigzip.c | ||
822 | - added gzdopen to reopen a file descriptor as gzFile | ||
823 | - added transparent reading of non-gziped files in gzread. | ||
824 | - fixed bug in gzread (don't read crc as data) | ||
825 | - fixed bug in destroy (gzio.c) (don't return Z_STREAM_END for gzclose). | ||
826 | - don't allocate big arrays in the stack (for MSDOS) | ||
827 | - fix some MSDOS compilation problems | ||
828 | |||
829 | Changes in 0.5: | ||
830 | - do real compression in deflate.c. Z_PARTIAL_FLUSH is supported but | ||
831 | not yet Z_FULL_FLUSH. | ||
832 | - support decompression but only in a single step (forced Z_FINISH) | ||
833 | - added opaque object for zalloc and zfree. | ||
834 | - added deflateReset and inflateReset | ||
835 | - added a variable zlib_version for consistency checking. | ||
836 | - renamed the 'filter' parameter of deflateInit2 as 'strategy'. | ||
837 | Added Z_FILTERED and Z_HUFFMAN_ONLY constants. | ||
838 | |||
839 | Changes in 0.4: | ||
840 | - avoid "zip" everywhere, use zlib instead of ziplib. | ||
841 | - suppress Z_BLOCK_FLUSH, interpret Z_PARTIAL_FLUSH as block flush | ||
842 | if compression method == 8. | ||
843 | - added adler32 and crc32 | ||
844 | - renamed deflateOptions as deflateInit2, call one or the other but not both | ||
845 | - added the method parameter for deflateInit2. | ||
846 | - added inflateInit2 | ||
847 | - simplied considerably deflateInit and inflateInit by not supporting | ||
848 | user-provided history buffer. This is supported only in deflateInit2 | ||
849 | and inflateInit2. | ||
850 | |||
851 | Changes in 0.3: | ||
852 | - prefix all macro names with Z_ | ||
853 | - use Z_FINISH instead of deflateEnd to finish compression. | ||
854 | - added Z_HUFFMAN_ONLY | ||
855 | - added gzerror() | ||
