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	defd366a41	zlib 1.2.5.3	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	3d85f02a09	Restore gzgetc function for binary compatibility. Newly compiled applications will use the gzgetc macro.	13 years ago

Mark Adler	fe61dfb8a2	zlib 1.2.5.2	13 years ago
Mark Adler	2556706d67	Document gzread() capability to read concurrently written files. Also since gzread() will no longer return an error for an incomplete gzip file, have gzclose() return an error if the last gzread() ended in the middle of a gzip stream.	13 years ago
Mark Adler	421c7a61f0	Have inflate() with Z_FINISH avoid the allocation of a window. inflate() avoided that allocation normally, until it was modified to update the window on a normal completion so that inflateResetKeep() could work. This patch restores that behavior, but only when Z_FINISH is used successfully to complete an inflation of a stream in a single call of inflate(). The comments in zlib.h have been updated accordingly.	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	6715208bdb	Change ON macro to Z_ARG to avoid application conflicts. Using "ON" was a dumb idea, since it is common to have macros with names like ON and OFF. In fact, defining the OF macro back in 1995 was a bad idea, but now we're stuck with it. Attempts to rename OF to something else breaks many applications.	13 years ago
Mark Adler	e8576790be	Note behavior of uncompress() to provide as much data as it can.	13 years ago
Mark Adler	6dbf1d1026	Add comment to gzdopen() in zlib.h to use dup() when using fileno(). A problem surfaced in a multi-threaded application where fileno() was used to get a file descriptor from an fopen(), which was then fed to gzdopen(). The problem occurred when the gzclose() followed by the fclose() tried to close the same file descriptor twice. If fclose() were not done, there would be a memory leak. The only way out is to dup() the file descriptor so that gzclose() closes the duplicated file descriptor, and fclose() closes the original file descriptor.	13 years ago
Mark Adler	5ab9f47745	Add #define ZLIB_CONST option to use const in the z_stream interface. This permits compilers to check for the proper treatment of next_in and msg in the z_stream structure. This is an option instead of the default in order to preserve backward compatibility. Some applications make use of the z_stream structure outside of zlib, and perform operations such as free(strm->next_in), which would not be permitted when next_in is const. The #define ZLIB_CONST needs to precede the #include "zlib.h">, in order to make next_in and msg const pointers in the z_stream type.	13 years ago
Mark Adler	77b47d55f1	Add undocumented inflateResetKeep() function for CAB file decoding. The Microsoft CAB file format compresses each block with completed deflate streams that depend on the sliding window history of the previous block in order to decode. inflateResetKeep() does what inflateReset() does, except the sliding window history from the previous inflate operation is retained.	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	26a99cd895	Add a transparent write mode to gzopen() when 'T' is in the mode.	13 years ago
Mark Adler	3c9d261809	Correct documentation of gzdirect() since junk at end now ignored.	13 years ago
Mark Adler	be959acf80	Clarify how gzopen() appends in zlib.h comments.	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
Mark Adler	acfc85772a	Change gzgetc() to a macro for speed (~40% speedup in testing).	13 years ago
Mark Adler	a9ae24b653	Change gzread() and related to ignore junk after gzip streams. Previously the new gz* functions (introduced in 1.2.4) would read and return raw data after the last gzip stream. This is inconsistent with the behavior of gzip and the previous versions of zlib. Now when one or more gzip streams have been decoded from the file, which is then followed by data that is not a gzip stream (as detemined by not finding the magic header), then that subsequent trailing garbage is ignored, and no error is returned.	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
