Revision 1.1, Sun Aug 29 13:43:46 2021 UTC (2 years, 8 months ago) by claudio
Branch: MAIN
CVS Tags: OPENBSD_7_5_BASE, OPENBSD_7_5, OPENBSD_7_4_BASE, OPENBSD_7_4, OPENBSD_7_3_BASE, OPENBSD_7_3, OPENBSD_7_2_BASE, OPENBSD_7_2, OPENBSD_7_1_BASE, OPENBSD_7_1, OPENBSD_7_0_BASE, OPENBSD_7_0, HEAD
Branch point for: OPENBSD_6_9 

Implement --exclude/exclude-file and --include/include-file.
Currently only simple include and excludes work, the advanced filters
introduced later in rsync are not implemented. It is unclear if the per
directory filters are something we want to implement. This requires
more modern protocols which openrsync is not able to handle right now.

This adds a special matching function to allow the ** matching which behaves
mostly like rsyncs version with the exception of how bad [] patterns are
expanded. For bad patterns openrsync follows more how fnmatch behaves and
not the somewhat strange rsync behaviour.

Not perfect but committing now so people can test and provide feedback.
