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.
