      Put gzflags() functionality back in zutil.c. · 55b8b5fe
      Mark Adler 提交于
      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.

      Enable dictionary setting in middle of stream, and keeping the dictionary. · afe7cf78
      Mark Adler 提交于
      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.

      Change ON macro to Z_ARG to avoid application conflicts. · 6715208b
      Mark Adler 提交于
      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.

      Add #define ZLIB_CONST option to use const in the z_stream interface. · 5ab9f477
      Mark Adler 提交于
      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.

      Add undocumented inflateResetKeep() function for CAB file decoding. · 77b47d55
      Mark Adler 提交于
      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.

      Add a ./config --solo option to make zlib subset with no libary use · f442c1e8
      Mark Adler 提交于
      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.

      Merge vestigial vsnprintf determination from zutil.h to gzguts.h. · 00c836e3
      Mark Adler 提交于
      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.
