|
|---|
| 293 |
|
|---|
| 294 | Changes in 1.0.4 (24 Jul 96)
|
|---|
| 295 | - In very rare conditions, deflate(s, Z_FINISH) could fail to produce an EOF
|
|---|
| 296 | bit, so the decompressor could decompress all the correct data but went
|
|---|
| 297 | on to attempt decompressing extra garbage data. This affected minigzip too.
|
|---|
| 298 | - zlibVersion and gzerror return const char* (needed for DLL)
|
|---|
| 299 | - port to RISCOS (no fdopen, no multiple dots, no unlink, no fileno)
|
|---|
| 300 | - use z_error only for DEBUG (avoid problem with DLLs)
|
|---|
| 301 |
|
|---|
| 302 | Changes in 1.0.3 (2 Jul 96)
|
|---|
| 303 | - use z_streamp instead of z_stream *, which is now a far pointer in MSDOS
|
|---|
| 304 | small and medium models; this makes the library incompatible with previous
|
|---|
| 305 | versions for these models. (No effect in large model or on other systems.)
|
|---|
| 306 | - return OK instead of BUF_ERROR if previous deflate call returned with
|
|---|
| 307 | avail_out as zero but there is nothing to do
|
|---|
| 308 | - added memcmp for non STDC compilers
|
|---|
| 309 | - define NO_DUMMY_DECL for more Mac compilers (.h files merged incorrectly)
|
|---|
| 310 | - define __32BIT__ if __386__ or i386 is defined (pb. with Watcom and SCO)
|
|---|
| 311 | - better check for 16-bit mode MSC (avoids problem with Symantec)
|
|---|
| 312 |
|
|---|
| 313 | Changes in 1.0.2 (23 May 96)
|
|---|
| 314 | - added Windows DLL support
|
|---|
| 315 | - added a function zlibVersion (for the DLL support)
|
|---|
| 316 | - fixed declarations using Bytef in infutil.c (pb with MSDOS medium model)
|
|---|
| 317 | - Bytef is define's instead of typedef'd only for Borland C
|
|---|
| 318 | - avoid reading uninitialized memory in example.c
|
|---|
| 319 | - mention in README that the zlib format is now RFC1950
|
|---|
| 320 | - updated Makefile.dj2
|
|---|
| 321 | - added algorithm.doc
|
|---|
| 322 |
|
|---|

|---|
| 324 | - fix array overlay in deflate.c which sometimes caused bad compressed data
|
|---|
| 325 | - fix inflate bug with empty stored block
|
|---|
| 326 | - fix MSDOS medium model which was broken in 0.99
|
|---|
| 327 | - fix deflateParams() which could generated bad compressed data.
|
|---|
| 328 | - Bytef is define'd instead of typedef'ed (work around Borland bug)
|
|---|
| 329 | - added an INDEX file
|
|---|
| 330 | - new makefiles for DJGPP (Makefile.dj2), 32-bit Borland (Makefile.b32),
|
|---|
| 331 | Watcom (Makefile.wat), Amiga SAS/C (Makefile.sas)
|
|---|
| 332 | - speed up adler32 for modern machines without auto-increment
|
|---|
| 333 | - added -ansi for IRIX in configure
|
|---|
| 334 | - static_init_done in trees.c is an int
|
|---|
| 335 | - define unlink as delete for VMS
|
|---|
| 336 | - fix configure for QNX
|
|---|
| 337 | - add configure branch for SCO and HPUX
|
|---|
| 338 | - avoid many warnings (unused variables, dead assignments, etc...)
|
|---|
| 339 | - no fdopen for BeOS
|
|---|
| 340 | - fix the Watcom fix for 32 bit mode (define FAR as empty)
|
|---|
| 341 | - removed redefinition of Byte for MKWERKS
|
|---|
| 342 | - work around an MWKERKS bug (incorrect merge of all .h files)
|
|---|
| 343 |

|
|---|
| 346 | - allow compression level 0 (no compression)

|---|
| 347 | - add deflateParams in zlib.h: allow dynamic change of compression level
|
|---|
| 348 | and compression strategy.
|
|---|
| 349 | - test large buffers and deflateParams in example.c
|
|---|
| 350 | - add optional "configure" to build zlib as a shared library
|
|---|
| 351 | - suppress Makefile.qnx, use configure instead
|
|---|
| 352 | - fixed deflate for 64-bit systems (detected on Cray)
|
|---|
| 353 | - fixed inflate_blocks for 64-bit systems (detected on Alpha)

|
|---|
| 355 | - always return Z_BUF_ERROR when deflate() has nothing to do
|
|---|
| 356 | - deflateInit and inflateInit are now macros to allow version checking
|
|---|
| 357 | - prefix all global functions and types with z_ with -DZ_PREFIX
|
|---|
| 358 | - make falloc completely reentrant (inftrees.c)
|
|---|
| 359 | - fixed very unlikely race condition in ct_static_init
|
|---|
| 360 | - free in reverse order of allocation to help memory manager
|
|---|
| 361 | - use zlib-1.0/* instead of zlib/* inside the tar.gz
|
|---|
| 362 | - make zlib warning-free with "gcc -O3 -Wall -Wwrite-strings -Wpointer-arith

|
|---|
| 365 | - deflateEnd now returns Z_DATA_ERROR if it was premature
|
|---|
| 366 | - deflate is finally (?) fully deterministic (no matches beyond end of input)
|
|---|
| 367 | - Document Z_SYNC_FLUSH
|
|---|
| 368 | - add uninstall in Makefile
|
|---|
| 369 | - Check for __cpluplus in zlib.h
|
|---|
| 370 | - Better test in ct_align for partial flush

|
|---|
| 376 | - ignore error if ranlib doesn't exist
|
|---|
| 377 | - call ranlib twice for NeXTSTEP
|
|---|
| 378 | - use exec_prefix instead of prefix for libz.a
|
|---|

|
|---|
| 385 | - in fcalloc, normalize pointer if size > 65520 bytes
|
|---|
| 386 | - don't use special fcalloc for 32 bit Borland C++
|
|---|
| 387 | - use STDC instead of __GO32__ to avoid redeclaring exit, calloc, etc...
|
|---|
| 388 | - use Z_BINARY instead of BINARY
|
|---|
| 389 | - document that gzclose after gzdopen will close the file
|

|
|---|
| 395 | - added get_crc_table
|
|---|
| 396 | - added a dimension to all arrays (Borland C can't count).
|

|
|---|
| 398 | - guard against multiple inclusion of *.h (for precompiled header on Mac)
|
|---|
| 399 | - Watcom C pretends to be Microsoft C small model even in 32 bit mode.
|
|---|
| 400 | - don't use unsized arrays to avoid silly warnings by Visual C++:
|
|---|
| 401 | warning C4746: 'inflate_mask' : unsized array treated as '__far'
|
|---|
| 402 | (what's wrong with far data in far model?).
|
|---|
| 403 | - define enum out of inflate_blocks_state to allow compilation with C++
|
|---|
| 404 |
|
|---|
| 405 | Changes in 0.95 (16 Aug 95)
|
|---|
| 406 | - fix MSDOS small and medium model (now easier to adapt to any compiler)
|
|---|
| 407 | - inlined send_bits
|
|---|
| 408 | - fix the final (:-) bug for deflate with flush (output was correct but
|
|---|
| 409 | not completely flushed in rare occasions).
|
|---|
| 410 | - default window size is same for compression and decompression
|
|---|
| 411 | (it's now sufficient to set MAX_WBITS in zconf.h).
|
|---|
| 412 | - voidp -> voidpf and voidnp -> voidp (for consistency with other
|
|---|
| 413 | typedefs and because voidnp was not near in large model).
|
|---|
| 414 |
|
|---|

|
|---|
| 436 | - Set binary mode for stdin/stdout in minigzip.c for OS/2
|
|---|
| 437 | - don't even use signed char in inflate (not portable enough)

| 446 | - optimized inflate on stored blocks.
|
|---|
| 447 | - untabify all sources to simplify patches
|
|---|
| 448 |
|

| 457 |
|
|---|
| 458 | Changes in 0.9 (1 May 95)

|---|
| 459 | - don't assume that zalloc clears the allocated memory (the TurboC bug
|
|---|
| 460 | was Mark's bug after all :)
|
|---|
| 461 | - let again gzread copy uncompressed data unchanged (was working in 0.71)
|
|---|
| 462 | - deflate(Z_FULL_FLUSH), inflateReset and inflateSync are now fully implemented
|
|---|
| 463 | - added a test of inflateSync in example.c
|
|---|
| 464 | - moved MAX_WBITS to zconf.h because users might want to change that.
|
|---|
| 465 | - document explicitly that zalloc(64K) on MSDOS must return a normalized
|
|---|
| 466 | pointer (zero offset)
|
|---|
| 467 | - added Makefiles for Microsoft C, Turbo C, Borland C++
|
|---|

|
|---|
| 471 | - added fast inflate (inffast.c)
|
|---|
| 472 | - deflate(Z_FINISH) now returns Z_STREAM_END when done. Warning: this
|
|---|
| 473 | is incompatible with previous versions of zlib which returned Z_OK.
|
|---|
| 474 | - work around a TurboC compiler bug (bad code for b << 0, see infutil.h)
|
|---|
| 475 | (actually that was not a compiler bug, see 0.81 above)

|
|---|
| 485 | Changes in 0.7 (14 April 95)
|
|---|
| 486 | - Added full inflate support.
|
|---|
| 487 | - Simplified the crc32() interface. The pre- and post-conditioning
|
|---|
| 488 | (one's complement) is now done inside crc32(). WARNING: this is
|
|---|
| 489 | incompatible with previous versions; see zlib.h for the new usage.
|
|---|
| 490 |
|
|---|
| 491 | Changes in 0.61 (12 April 95)
|
|---|
| 492 | - workaround for a bug in TurboC. example and minigzip now work on MSDOS.

|
|---|

|
|---|
| 501 | - fix some MSDOS compilation problems
|
|---|
| 502 |
|
|---|
| 503 | Changes in 0.5:
|
|---|
| 504 | - do real compression in deflate.c. Z_PARTIAL_FLUSH is supported but
|
|---|
| 505 | not yet Z_FULL_FLUSH.
|
|---|
| 506 | - support decompression but only in a single step (forced Z_FINISH)
|
|---|
| 507 | - added opaque object for zalloc and zfree.
|
|---|
| 508 | - added deflateReset and inflateReset
|
|---|
| 509 | - added a variable zlib_version for consistency checking.

|
|---|
| 513 | Changes in 0.4:
|
|---|
| 514 | - avoid "zip" everywhere, use zlib instead of ziplib.
|
|---|
| 515 | - suppress Z_BLOCK_FLUSH, interpret Z_PARTIAL_FLUSH as block flush

| 516 | if compression method == 8.
|
|---|

|
|---|
| 518 | - renamed deflateOptions as deflateInit2, call one or the other but not both
|
|---|
| 519 | - added the method parameter for deflateInit2.
|
|---|
| 520 | - added inflateInit2
|
|---|
| 521 | - simplied considerably deflateInit and inflateInit by not supporting
|
|---|
| 522 | user-provided history buffer. This is supported only in deflateInit2
|
|---|
| 523 | and inflateInit2.
|
|---|
| 524 |
|
|---|
| 525 | Changes in 0.3:
|
|---|
| 526 | - prefix all macro names with Z_
|
|---|
| 527 | - use Z_FINISH instead of deflateEnd to finish compression.
