Mark Adler	9aaec95e82	Use post-increment only in inffast.c. An old inffast.c optimization turns out to not be optimal anymore with modern compilers, and furthermore was not compliant with the C standard, for which decrementing a pointer before its allocated memory is undefined. Per the recommendation of a security audit of the zlib code by Trail of Bits and TrustInSoft, in support of the Mozilla Foundation, this "optimization" was removed, in order to avoid the possibility of undefined behavior.	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	33a7aff45d	Fix typo.	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	93b0af4aa7	Correct the size of the inflate state in the comments.	8 years ago
Mark Adler	70a8763b71	Fix typo in blast.c.	9 years ago
Mark Adler	2bcfc31188	Add configure.log to .gitignore.	9 years ago
Mark Adler	4f1df003ed	Loop on write() calls in gzwrite.c in case of non-blocking I/O.	9 years ago
Mark Adler	4423fef8dc	Fix gzseek() problem on MinGW due to buggy _lseeki64 there.	9 years ago
Mark Adler	6cef1de740	Fix bug that accepted invalid zlib header when windowBits is zero. When windowBits is zero, the size of the sliding window comes from the zlib header. The allowed values of the four-bit field are 0..7, but when windowBits is zero, values greater than 7 are permitted and acted upon, resulting in large, mostly unused memory allocations. This fix rejects such invalid zlib headers.	9 years ago
Mark Adler	8f1b3744e5	Use a consistent and more modern approach to not use a parameter. A remarkably creative and diverse set of approaches to letting the compiler know that opaque was being used when it wasn't is changed by this commit to the more standard (void)opaque.	9 years ago
Mark Adler	f77c982344	Use UTF-8 for non-ASCII characters in ChangeLog.	9 years ago
Mark Adler	44ae761dc2	Clean up portability for shifts and integer sizes.	9 years ago
Mark Adler	e54e129940	Avoid shifts of negative values inflateMark(). The C standard says that bit shifts of negative integers is undefined. This casts to unsigned values to assure a known result.	9 years ago
Mark Adler	27ef026603	Fix typo.	10 years ago
Mark Adler	82e9dc6093	Use const for static tree descriptions in deflate. This is in order to permit shared memory for these structures.	10 years ago
Mark Adler	55d98b4c30	Allow building zlib outside of the source directory. To build, simply run configure from the source directory by specifying its path. That path will be used to find the source files. The source directory will not be touched. All new and modified files will be made in the current directory. Discovered in the process that not all makes understand % or $<, and not all compilers understand -include or -I-. This required a larger Makefile.in with explicit dependencies.	10 years ago
Mark Adler	bfcace04f9	Do not initialize unsigned with -1 in compress.c uncompr.c. Sun compiler complained. Use (unsigned)0 - 1 instead.	10 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	2fc6d66797	Define _POSIX_SOURCE to enable POSIX extensions on some systems.	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	c901a34c92	Avoid uninitialized access by gzclose_w().	10 years ago
Mark Adler	51a223def4	Avoid use of DEBUG macro -- change to ZLIB_DEBUG.	10 years ago
Mark Adler	0b22337126	Avoid use of reallocf() in test/infcover.c.	10 years ago
Mark Adler	0db8fd3714	Fix inflateInit2() bug when windowBits is 16 or 32. A windowBits value of 0, 16, or 32 gets the window bits from the zlib header. However there is no zlib header for 16, or for 32 when the input is gzip. This commit sets the window bits for inflate to 15 if a gzip stream is detected and windowBits was 16 or 32.	10 years ago
Mark Adler	b56d1c62ee	Add comment about not using windowBits of 8 for deflate().	10 years ago
Mark Adler	e7ebb399d7	Put license in zlib.3 man page. Previously there was a confusing reference to a "distribution directory".	10 years ago
Mark Adler	95698093f0	Improve speed of gzprintf() in transparent mode.	10 years ago
Mark Adler	8a979f6c79	Avoid left shift of a negative value in flush rank calculation. The C standard permits an undefined result for a left shift of a negative value.	10 years ago
Mark Adler	9859a94c10	Remedy Coverity warning. [Randers-Pehrson]	10 years ago
Mark Adler	5370d99a2a	Add inflateCodesUsed() function for internal use.	10 years ago
Mark Adler	283520baf7	Fix bug in test/example.c where error code not saved.	11 years ago
Mark Adler	9cbda797c1	Note in zlib.h that compress() uses Z_DEFAULT_COMPRESSION.	11 years ago
Mark Adler	7d54c69413	Fix uncompress() to work on lengths more than a maximum unsigned.	11 years ago
Mark Adler	f898bbed89	Fix compress() to work on lengths more than a maximum unsigned.	11 years ago
Mark Adler	72c70060d8	Assure that gzoffset() is correct when appending. An open() with O_APPEND followed by an lseek() to determine the position will return zero for a non-empty file, even though the next write will start at the end of the file. This commit works around that by doing an lseek() to the end when appending.	11 years ago
Mark Adler	799c87c0d8	Improve contrib/blast to return unused bytes. Fix the test code to report the count of unused bytes at the end correctly. Add the ability to provide initial input to blast().	12 years ago

Mark Adler	f5ec26344f	Update some copyright years.	12 years ago
Mark Adler	bddc968b14	Do not force Z_CONST for C++. Forcing Z_CONST resulted in an issue when compiling Firefox. Now if someone wants to compile zlib as C++ code (which it isn't), now they will need to #define Z_CONST themselves.	12 years ago
Mark Adler	5481269e1f	Update contrib/minizip/iowin32.c for Windows RT [Vollant].	12 years ago
