zlib 1.2.0.8
2011-09-10 02:23:14 -04:00
* ZLIB.INC - Interface to the general purpose compression library
*
* ILE RPG400 version by Patrick Monnerat, DATASPHERE.
Change version number to 1.2.8.1.
2013-05-03 02:12:54 -04:00
* Version 1.2.8.1
zlib 1.2.0.8
2011-09-10 02:23:14 -04:00
*
*
* WARNING:
* Procedures inflateInit(), inflateInit2(), deflateInit(),
* deflateInit2() and inflateBackInit() need to be called with
* two additional arguments:
* the package version string and the stream control structure.
* size. This is needed because RPG lacks some macro feature.
* Call these procedures as:
* inflateInit(...: ZLIB_VERSION: %size(z_stream))

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.

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.

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.
