Mark Adler	61b91f27f8	Make z_size_t unsigned long for non-standard C. Also declare z_size_t when compiling solo.	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	3f8c768745	Fix compile option for when z_size_t needs to be a long long.	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	9dc5a8585f	Speed up deflation for level 0 (storing). The previous code slid the window and the hash table and copied every input byte three times in order to just write the data as stored blocks with no compression. This commit minimizes sliding and copying, especially for large input and output buffers. Level 0 compression is now more than 20 times faster than before the commit. Most of the speedup is due to deferring hash table slides until deflateParams() is called to change the compression level away from 0. More speedup is due to copying directly from next_in to next_out when the amounts of available input data and output space permit it, avoiding the intermediate pending buffer. Additionally, only the last 32K of the used input data is copied back to the sliding window when large input buffers are provided.	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	1101ea79c6	Explicitly ignore a return value in gzwrite.c.	8 years ago
Mark Adler	21c66cd5ac	Increase verbosity required to warn about bit length overflow. When debugging the Huffman coding would warn about resulting codes greater than 15 bits in length. This is handled properly, and is not uncommon. This increases the verbosity of the warning by one, so that it is not displayed by default.	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	9674807c82	Fix bugs in creating a very large gzip header.	8 years ago
Mark Adler	fc130cdd9f	Add --debug (-d) option to ./configure to define ZLIB_DEBUG.	8 years ago
Mark Adler	a456d898bb	Use memcpy for stored blocks. This speeds up level 0 by about a factor of three, as compared to the previous byte-at-a-time loop. We can do much better though. A later commit avoids this copy for level 0 with large buffers, instead copying directly from the input to the output. This commit still speeds up storing incompressible data found when compressing normally.	8 years ago
Mark Adler	03614c56ad	Fix some typos.	8 years ago
Mark Adler	94575859cf	Fix bug when level 0 used with Z_HUFFMAN or Z_RLE. Compression level 0 requests no compression, using only stored blocks. When Z_HUFFMAN or Z_RLE was used with level 0 (granted, an odd choice, but permitted), the resulting blocks were mostly fixed or dynamic. The reason is that deflate_stored() was not being called in that case. The compressed data was valid, but it was not what the application requested. This commit assures that only stored blocks are emitted for compression level 0, regardless of the strategy selected.	8 years ago
Mark Adler	bedea2483b	Clean up and comment the use of local for static.	8 years ago
Mark Adler	ce12c5cd00	Make a noble effort at setting OS_CODE correctly. This updates the OS_CODE determination at compile time to match as closely as possible the operating system mappings documented in the PKWare APPNOTE.TXT version 6.3.4, section 4.4.2.2. That byte in the gzip header is used by nobody for anything, as far as I can tell. However we might as well try to set it appropriately.	8 years ago
Mark Adler	b516b4bdd7	Do a more thorough check of the state for every stream call. This verifies that the state has been initialized, that it is the expected type of state, deflate or inflate, and that at least the first several bytes of the internal state have not been clobbered.	8 years ago
Mark Adler	77fd7e56bf	Document the rejection of 256-byte window requests in zlib.h.	8 years ago
Mark Adler	049578f0a1	Reject a window size of 256 bytes if not using the zlib wrapper. There is a bug in deflate for windowBits == 8 (256-byte window). As a result, zlib silently changes a request for 8 to a request for 9 (512-byte window), and sets the zlib header accordingly so that the decompressor knows to use a 512-byte window. However if deflateInit2() is used for raw deflate or gzip streams, then there is no indication that the request was not honored, and the application might assume that it can use a 256-byte window when decompressing. This commit returns an error if the user requests a 256-byte window when using raw deflate or gzip encoding.	8 years ago
Mark Adler	a0bf0f31d3	Avoid obfuscating use of default case in inftrees.c.	8 years ago
Mark Adler	da64f1730c	Move macro definition in deflate.c to where it is used. This avoid defining a macro that is never used when not debugging.	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	7d6956b6a1	Make globals in examples local to compilation unit.	8 years ago
Mark Adler	8b95fa19cd	Add --warn option to ./configure, instead of environment variable.	8 years ago
