[Csync2] Partial path excludes?

[Tony Muka]

Sorry to drag up this old message, but I didn't see much documentation
on this issue, and wanted to share my findings in trying to exclude
.svn folders with csync2.

After trying many failing variations of

exclude .svn
exclude .snv*
exclude .svn/*
exclude ".svn/*"
exclude *svn*

the only thing that worked was

exclude /var/www/*/htdocs/.svn/*;
exclude /var/www/*/htdocs/*/.svn/*;
exclude /var/www/*/htdocs/*/*/.svn/*;
exclude /var/www/*/htdocs/*/*/*/.svn/*;
exclude /var/www/*/htdocs/*/*/*/*/.svn/*;
exclude /var/www/*/htdocs/*/*/*/*/*/.svn/*;
exclude /var/www/*/htdocs/*/*/*/*/*/*/.svn/*;
exclude /var/www/*/htdocs/*/*/*/*/*/*/*/.svn/*;
exclude /var/www/*/htdocs/*/*/*/*/*/*/*/*/.svn/*;
exclude /var/www/*/htdocs/*/*/*/*/*/*/*/*/*/.svn/*;

It would really be nice if there was a way to use one simple rule to
exclude the descendants of any .svn folder, but for now, this works.

I probably don't have a good enough reason to exclude the .svn paths
to use this case as a justification for the feature, etc... Excluding
the .svn folders does cut my disk usage by 50% on the slave nodes.*

I have something like that in my csync2.cfg:

	exclude /the_base_path_to_my_sites/*/home/www/views_c/*;

It works. However, my case is quite easy: the '/*/' never contains paths but
always a single dir (say, '/domain.tld/'). I don't know if the '/*/' "thing"
matches against a path (say, '/this/is/a/customer/path/'), but I think it
doesn't...

In this case, however, you may try to evince a few patterns in the paths you
want to exclude, then exclude each of them. Another way could be to
regularly use some external tool (like a script invoking 'find', in example)
to discover the paths containing a 'views_c' or 'template_c' directory, then
automatically add to csync2.cfg an exclude directive for each of these path
and, finally, csync the csync2.cfg file (this is important: csync2 mail fail
otherwise!).

Please also note that excluding a dir in a path may impede synchronizing the
removal of the whole path, because the path will not be empty in the target
system. So, if you want also to sync the removal of a site, the better thing
is to avoid 'exclude' in that path. By the way, the kind of exclusion you
want to do is probably due more to improving synch speed than to a real
need, isn't it? It may be worth avoiding this optimization if you prefer to
limit manual adjustments at a minimum.
