Mark Adler	e9d5486e66	Remove K&R function definitions from zlib. C2X has removed K&R definitions from the C function syntax. Though the standard has not yet been approved, some high-profile compilers are now issuing warnings when such definitions are encountered.	2 years ago
Mark Adler	02a6049eb3	Fix crash when gzsetparams() attempted for transparent write. gzsetparams() now returns a Z_STREAM_ERROR in this case.	2 years ago
Mark Adler	84c6716a48	Minor formatting improvements. No code changes.	2 years ago
Mark Adler	21767c654d	zlib 1.2.12	3 years ago

Mark Adler	90287635ef	Return an error if the gzputs string length can't fit in an int.	8 years ago
Mark Adler	793ad7f559	Avoid some conversion warnings in gzread.c and gzwrite.c.	8 years ago
Mark Adler	cacf7f1d4e	zlib 1.2.11	8 years ago
Mark Adler	0b5c158cc7	Fix bug in gzwrite.c that produced corrupt gzip files.	8 years ago
Mark Adler	2fa463bacf	zlib 1.2.9	8 years ago
Mark Adler	cca27e95cf	Avoid the need for ssize_t. Limit read() and write() requests to sizes that fit in an int. This allows storing the return value in an int, and avoiding the need to use or construct an ssize_t type. This is required for Microsoft C, whose _read and _write functions take an unsigned request and return an int.	8 years ago
Mark Adler	8f147c3d12	Avoid some random compiler warnings on various platforms.	8 years ago
Mark Adler	77bc4f8944	Add gzfwrite(), duplicating the interface of fwrite().	8 years ago
Mark Adler	ca50ebd4df	Create z_size_t and z_ssize_t types. Normally these are set to size_t and ssize_t. But if they do not exist, then they are set to the smallest integer type that can contain a pointer. size_t is unsigned and ssize_t is signed.	8 years ago
Mark Adler	c5ee34c28a	Don't need to emit an empty fixed block when changing parameters. gzsetparams() was using Z_PARTIAL_FLUSH when it could use Z_BLOCK instead. This commit uses Z_BLOCK, which avoids emitting an unnecessary ten bits into the stream.	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	1101ea79c6	Explicitly ignore a return value in gzwrite.c.	8 years ago
Mark Adler	7096424f23	Clean up type conversions.	8 years ago
Mark Adler	4f1df003ed	Loop on write() calls in gzwrite.c in case of non-blocking I/O.	9 years ago
Mark Adler	c901a34c92	Avoid uninitialized access by gzclose_w().	9 years ago
Mark Adler	95698093f0	Improve speed of gzprintf() in transparent mode.	10 years ago
Mark Adler	70252daf89	Add casts in gzwrite.c for pointer differences.	12 years ago
Mark Adler	0b16609409	zlib 1.2.7.1	12 years ago
Mark Adler	e9f0b78443	Add casts and consts to ease user conversion to C++. You would still need to run zlib2ansi on all of the *.c files.	12 years ago
Mark Adler	b06dee4369	Add gzvprintf() as an undocumented function in zlib. The function is only available if stdarg.h is available.	12 years ago
Mark Adler	c4888637ea	Fix bug in gzclose() when gzwrite() runs out of memory. If the deflateInit2() called for the first gzwrite() failed with a Z_MEM_ERROR, then a subsequent gzclose() would try to free an already freed pointer. This fixes that.	12 years ago
Mark Adler	0cf495a1ca	Fix bug where gzopen(), gzclose() would write an empty file. A gzopen() to write (mode "w") followed immediately by a gzclose() would output an empty zero-length file. What it should do is write an empty gzip file, with the gzip header, empty deflate content, and gzip trailer totalling 20 bytes. This fixes it to do that.	12 years ago
Mark Adler	aa566e86c4	Fix unintialized value bug in gzputc() introduced by const patches. Avoid the use of an uninitialized value when the write buffers have not been initialized. A recent change to avoid the use of strm-> next_in in order to resolve some const conflicts added the use of state->in in its place. This patch avoids the use of state->in when it is not initialized. Nothing bad would actually happen, since two variables set to the same unintialized value are subtracted. However valgrind was rightly complaining. So this fixes that.	12 years ago
Mark Adler	62d6112a79	Clean up the usage of z_const and respect const usage within zlib. This patch allows zlib to compile cleanly with the -Wcast-qual gcc warning enabled, but only if ZLIB_CONST is defined, which adds const to next_in and msg in z_stream and in the in_func prototype. A --const option is added to ./configure which adds -DZLIB_CONST to the compile flags, and adds -Wcast-qual to the compile flags when ZLIBGCCWARN is set in the environment.	12 years ago
Mark Adler	53bfe01cea	Fix bug in gzclose_w() when gzwrite() fails to allocate memory.	13 years ago
Mark Adler	05de38d11e	Cast to char * in gzprintf to avoid warnings [Zinser].	13 years ago
Mark Adler	55b8b5fec1	Put gzflags() functionality back in zutil.c. gzflags() was put in gzwrite.c in order to be compiled exactly the same as gzprintf(), so that it was guaranteed to return the correct information. However that causes a static linkage to zlib to bring in many routines that are often not used. All that is required to duplicate the compilation environment of gzprintf() is to include gzguts.h. So that is now done in zutil.c to assure that the correct flags are returned.	13 years ago
Mark Adler	e75de023b6	zlib 1.2.6	13 years ago
Mark Adler	22eb01184f	Have gzputc return the character written instead of the argument. When successful, gzputc would return the second argument. If the second argument were -1, gzputc would return -1 instead of the character written, which was 255. However the -1 would not be distinguishable from an error. Now gzputc returns 255 in that case.	13 years ago
Mark Adler	850a198ff1	Avoid use of Z_BUF_ERROR in gz* functions except for premature EOF. Z_BUF_ERROR was also being used for an unsuccessful gzungetc and for buffer lengths that didn't fit in an int. Those uses were changed to Z_DATA_ERROR in order to assure that Z_BUF_ERROR occurs only when a premature end of input occurs, indicating that gzclearerr() can be used.	13 years ago
Mark Adler	fb00fda903	Fix gzwrite.c to accommodate reduced memory zlib compilation. gzwrite.c had hard-coded parameters to deflateInit2() which could contradict compile-time options for the use of less memory and fewer code bits. This patch suggested by Karsten Saunte fixes that.	13 years ago
Mark Adler	26a99cd895	Add a transparent write mode to gzopen() when 'T' is in the mode.	13 years ago
Mark Adler	00c836e325	Merge vestigial vsnprintf determination from zutil.h to gzguts.h. This also moves some of the same from zconf.h to gzguts.h. A new function, gzflags(), was created to pass the compilation flags related to vsnprintf usage back to zlibCompileFlags() in zutil.c. In the process, various compiler configuration files were updated to include gzflags(), as well as the new gzgetc_() function added when the gzgetc() macro was introduced in a previous patch.	13 years ago
Mark Adler	8768ba98af	Fix gzclose() to return the actual error last encountered.	13 years ago
