Author	SHA1	Message	Date
Mark Adler	e54494e6bc	Clarify gz* function interfaces, referring to parameter names.	4 years ago
Mark Adler	0e96d8e7c7	Explicitly note that the 32-bit check values are 32 bits.	6 years ago
Mark Adler	f8719f5ae5	Speed up software CRC-32 computation by a factor of 1.5 to 3. Use the interleaved method of Kadatch and Jenkins in order to make use of pipelined instructions through multiple ALUs in a single core. This also speeds up and simplifies the combination of CRCs, and updates the functions to pre-calculate and use an operator for CRC combination.	6 years ago
Mark Adler	41d86c73b2	Add crc32_combine_gen() and crc32_combine_op() for fast combines. When the same len2 is used repeatedly, it is faster to use crc32_combine_gen() to generate an operator, that is then used to combine CRCs with crc32_combine_op().	6 years ago
Mark Adler	e99813dbfe	Correct the initialization requirements for deflateInit2().	7 years ago
Mark Adler	bf88202e31	Emphasize the need to continue decompressing gzip members.	7 years ago
Mark Adler	a577351394	Make the names in functions declarations identical to definitions.	7 years ago
Mark Adler	f9694097dd	Permit a deflateParams() parameter change as soon as possible. This commit allows a parameter change even if the input data has not all been compressed and copied to the application output buffer, so long as all of the input data has been compressed to the internal pending output buffer. This also allows an immediate deflateParams change so long as there have been no deflate calls since initialization or reset.	8 years ago
Mark Adler	5ff989033e	Cygwin does not have _wopen(), so do not create gzopen_w() there.	8 years ago
Mark Adler	7d60b86782	Change version number to 1.2.11.1.	8 years ago
Mark Adler	cacf7f1d4e	zlib 1.2.11	8 years ago
Mark Adler	cbbd20302c	Permit immediate deflateParams changes before any deflate input. This permits deflateParams to change the strategy and level right after deflateInit, without having to wait until a header has been written. The parameters can be changed immediately up until the first deflate call that consumes any input data.	8 years ago
Mark Adler	11ceaed751	Change version number to 1.2.10.1.	8 years ago
Mark Adler	4a090adef8	zlib 1.2.10	8 years ago
Mark Adler	52aa5501ec	Minor edits and clarifications of comments.	8 years ago
Mark Adler	20e472546e	Change version number to zlib 1.2.9.1.	8 years ago
Mark Adler	2fa463bacf	zlib 1.2.9	8 years ago
Mark Adler	b9ae6f0079	Add crc32_z() and adler32_z() functions with size_t lengths.	8 years ago
Mark Adler	50dca6d127	Fix init macros to use z_ prefix when requested.	8 years ago
Mark Adler	ee7d7b5dda	Add deflateGetDictionary() function. Per request, but its utility is likely to be very limited. See the comments in zlib.h.	8 years ago
Mark Adler	77bc4f8944	Add gzfwrite(), duplicating the interface of fwrite().	8 years ago
Mark Adler	44dfd831d2	Add gzfread(), duplicating the interface of fread().	8 years ago
Mark Adler	123f9cfaf7	Clean up gz* function return values. In some cases the return values did not match the documentation, or the documentation did not document all of the return values. gzprintf() now consistently returns negative values on error, which matches the behavior of the stdio fprintf() function.	8 years ago
Mark Adler	7161ad76e2	Assure that deflateParams() will not switch functions mid-block. This alters the specification in zlib.h, so that deflateParams() will not change any parameters if there is not enough output space in the event that a block is emitted in order to allow switching the compression function.	8 years ago
Mark Adler	37281ac222	Add uncompress2() function, which returns the input size used.	8 years ago
Mark Adler	001300d0d9	Minor edits to the documentation in source file contents.	8 years ago
Mark Adler	03614c56ad	Fix some typos.	8 years ago
Mark Adler	77fd7e56bf	Document the rejection of 256-byte window requests in zlib.h.	8 years ago
Mark Adler	ebbc57393d	Avoid recursive gzgetc() macro call. Recursive macro calls are normally caught by the preprocessor and avoided. This commit avoids the possibility of a problem entirely.	8 years ago
Mark Adler	7096424f23	Clean up type conversions.	8 years ago
Mark Adler	3fb251b363	Remove dummy structure declarations for old buggy compilers. While woolly mammoths still roamed the Earth and before Atlantis sunk into the ocean, there were C compilers that could not handle forward structure references, e.g. "struct name;". zlib dutifully provided a work-around for such compilers. That work-around is no longer needed, and, per the recommendation of a security audit of the zlib code by Trail of Bits and TrustInSoft, in support of the Mozilla Foundation, should be removed since what a compiler will do with this is technically undefined. From the report: "there is no telling what interactions the bug could have in the future with link-time optimizations and type-based alias analyses, both features that are present (but not default) in clang."	8 years ago
Mark Adler	9852c209ac	Add option to not compute or check check values. The undocumented (except in these commit comments) function inflateValidate(strm, check) can be called after an inflateInit(), inflateInit2(), or inflateReset2() with check equal to zero to turn off the check value (CRC-32 or Adler-32) computation and comparison. Calling with check not equal to zero turns checking back on. This should only be called immediately after the init or reset function. inflateReset() does not change the state, so a previous inflateValidate() setting will remain in effect. This also turns off validation of the gzip header CRC when present. This should only be used when a zlib or gzip stream has already been checked, and repeated decompressions of the same stream no longer need to be validated.	8 years ago
Mark Adler	44ae761dc2	Clean up portability for shifts and integer sizes.	9 years ago
Mark Adler	43bfaba3d7	Align deflateParams() and its documentation in zlib.h. This updates the documentation to reflect the behavior of deflateParams() when it is not able to compress all of the input data provided so far due to insufficient output space. It also assures that data provided is compressed before the parameter changes, even if at the beginning of the stream.	10 years ago
Mark Adler	b4ce6caf09	Compile the gzopen_w() function when __CYGWIN__ defined.	10 years ago
Mark Adler	5701f48cf5	Clarify deflateReset() documentation. It previously could have been misinterpreted to mean that parameter changes after deflateInit2() would be reversed, which is not the case.	10 years ago
Mark Adler	51a223def4	Avoid use of DEBUG macro -- change to ZLIB_DEBUG.	10 years ago
Mark Adler	b56d1c62ee	Add comment about not using windowBits of 8 for deflate().	10 years ago
Mark Adler	95698093f0	Improve speed of gzprintf() in transparent mode.	10 years ago
Mark Adler	9cbda797c1	Note in zlib.h that compress() uses Z_DEFAULT_COMPRESSION.	11 years ago
