Mark Adler	c661c374e8	Do not return Z_BUF_ERROR if deflateParam() has nothing to write. If the compressed data was already at a block boundary, then deflateParam() would report Z_BUF_ERROR, because there was nothing to write. With this patch, Z_OK is returned in that case.	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	68f64498c2	Make sure that no extra inserting is done if the strategy changes.	13 years ago
Mark Adler	4f5779a8e7	Insert the first two strings in the hash table after a flush. This allows deflate to generate the same output when continuing after a Z_SYNC_FLUSH vs. using deflateSetDictionary() after a Z_FULL_FLUSH or a deflateReset(). It also slightly improves compression when flushing by providing two more strings to possibly match at the start of the new block.	13 years ago
Mark Adler	0b828b4aa6	Write out all of the available bits when using Z_BLOCK. Previously, the bit buffer would hold 1 to 16 bits after "all" of the output is provided after a Z_BLOCK deflate() call. Now at most seven bits remain in the output buffer after Z_BLOCK. flush_pending() now flushes the bit buffer before copying out the byte buffer, in order for it to really flush as much as possible.	13 years ago
Mark Adler	263b1a05b0	Allow deflatePrime() to insert bits in the middle of a stream. This allows the insertion of multiple empty static blocks for the purpose of efficiently bringing a stream to a byte boundary.	13 years ago
Mark Adler	19761b8506	Permit Z_NULL arguments to deflatePending. This avoids having to create useless variables for return values that aren't needed.	13 years ago
Mark Adler	9d55abc969	Avoid extraneous empty blocks when doing empty flushes. Previously when doing an empty flush, a extra static or stored block could be emitted before the requested empty static or stored block. This patch prevents the emission of empty blocks by the deflate_* functions.	13 years ago
Mark Adler	f1ebdd6a9c	Permit stronger flushes after Z_BLOCK flushes. The incorporation of the Z_BLOCK flush did not update the rejection of lower ranked flushes immediately after higher ranked flushes with no more input data. This prevented an empty Z_SYNC_FLUSH right after a Z_BLOCK flush, which would be desired to bring the deflate stream to a byte boundary conditionally on whether or not it was already at a byte boundary. This patch re-ranks Z_BLOCK above Z_NO_FLUSH but below Z_PARTIAL_FLUSH, allowing stronger empty flushes to follow a Z_BLOCK flush.	13 years ago
Mark Adler	df60b50769	Change version numbers to 1.2.5.3.	13 years ago
Mark Adler	afe7cf78d5	Enable dictionary setting in middle of stream, and keeping the dictionary. This patch adds the deflateResetKeep() function to retain the sliding window for the next deflate operation, and fixes an inflateResetKeep() problem that came from inflate() not updating the window when the stream completed. This enables constructing and decompressing a series of concatenated deflate streams where each can depend on the history of uncompressed data that precedes it. This generalizes deflateSetDictionary() and inflateSetDictionary() to permit setting the dictionary in the middle of a stream for raw deflate and inflate. This in combination with the Keep functions enables a scheme for updating files block by block with the transmission of compressed data, where blocks are sent with deflateResetKeep() to retain history for better compression, and deflateSetDictionary() is used for blocks already present at the receiver to skip compression but insert that data in the history, again for better compression. The corresponding inflate calls are done on the receiver side.	13 years ago
Mark Adler	f442c1e89e	Add a ./config --solo option to make zlib subset with no libary use A common request has been the ability to compile zlib to require no other libraries. This --solo option provides that ability. The price is that the gz, compress, and uncompress functions are eliminated, and that the user must provide memory allocation and free routines to deflate and inflate when initializing.	13 years ago
Mark Adler	1250ac745d	Add assertions to fill_window() in deflate.c to match comments.	13 years ago
Mark Adler	5cf0930ba5	Assure that high-water mark initialization is always applied in deflate.	13 years ago
Mark Adler	faa03d5141	Avoid searching past window for Z_RLE strategy. Without this, Z_RLE could under some circumstances read one byte past the end of the allocated sliding window. This would normally not be a problem unless the window is right at the end of an allocated page, or if a bounds checker is being used.	13 years ago
Mark Adler	d6cbbd5c64	Change version numbers to 1.2.5.2 and release dates Also added "-motley" to ZLIB_VERSION in zlib.h, so that versions in-between 1.2.5.1 and 1.2.5.2 that are pulled down from github can be identified as such if bugs are reported on them.	13 years ago
