Annotation of embedaddon/rsync/zlib/README.rsync, revision 1.1.1.1

1.1       misho       1: READ THIS BEFORE TRYING TO DYNAMICALLY LINK RSYNC AND ZLIB!
                      2: 
                      3: zlib has been adapted slightly for use in rsync. Please don't bother
                      4: the zlib authors with problems related to the use of zlib in rsync as
                      5: any bugs are likely to be our fault and not theirs.
                      6: 
                      7: Specific changes that have been made to zlib for rsync include:
                      8: 
                      9: - add Z_INSERT_ONLY to allow for efficient history updating without
                     10:   actually emitting any data. This is used to compress the matched
                     11:   blocks that don't cross the wire, which gives better compression
                     12:   ratios on the literal data.
                     13: 
                     14: - fixed a number of minor compilation issues. (redefinition of MAX and
                     15:   other such trivial things)
                     16: 
                     17: - include rsync.h to ensure that we get a consistent set of includes
                     18:   for all C code in rsync and to take advantage of autoconf
                     19: 
                     20: As a result of the first item, the streams from rsync's version of
                     21: zlib are *not compatible* with those produced by the upstream version
                     22: of rsync.  In other words, if you link rsync against your system's
                     23: copy, it will not be able to interoperate with any other version if
                     24: the -z option is used.  (Sorry.  Sometimes standard is better than
                     25: better.)
                     26: 
                     27: The rsync maintainers hope to fix this problem in the future by either
                     28: merging our changes into the upstream version, or backing them out of
                     29: rsync in a way that preserves wire compatibility.  But in the meantime
                     30: this version must be maintained in parallel.
