Hi,

Part-time listener, first time caller ;-)  Came across this message, and
thought I'd share...

Back in mid-December I started using rev 1744 of the vcauth-reorg branch, in
order to get the svnauthz functionality.  I wanted to be able to use multiple
authz files, and found that I could achieve this by _not_ specifying an
authzfile in the [authz-svnauthz] section, and by creating per-repo stanzas
that used root-{reponame}, which look like:

> [root-repo1/options]
> authorizer = svnauthz
> [root-repo1/authz-svnauthz]
> authzfile = /path/to/svn/repo1/conf/authz
>
> [root-repo2/options]
> authorizer = svnauthz
> [root-repo2/authz-svnauthz]
> authzfile = /other/path/svn/repo2/conf/authz


...and figured this would work, based on what's defined in lib/config.py

170     params = {}
171     authz_section = 'authz-%s' % (authorizer)
172     if rootname:
173       root_authz_section = 'root-%s/authz-%s' % (rootname, authorizer)
174     for section in self.parser.sections():
175       if section == authz_section \
176          or (rootname and section == root_authz_section):
177         params.update(self.parser.items(section))
178     return params

...which I presumed was there precisely for this purpose, and appeared to do
the Right Thing, i.e., I can define and use multiple authz files, one per repo.
And as I understand it, this is similar to, but not the same as the vhost
configuration.

I tried this again just now against head (2015), and it still appears to be
working as in the earlier release (so far, at least).  So, what am I doing
incorrectly to make this work? :-D

I'd vote for that one, too.
