Having both WebDAV access and being able to hotcopy a Subversion repository
I use the Subversion version control system for a couple of things. Every night I make a backup of the repository to a remote server, having hot-backup.py
run by a user in the svnusers
group without further privileges. So all files in the repositories should be group readable and writable. This is relatively easy to accomplish for local and svn+ssh
users with the Subversion book. However, for access via WebDAV there are more steps and they're not so easy to find out:
- Change group ownership of all files in the repository to
svnusers
. - Set the SGID permission bit on the
dav/
,db/
andlocks/
directories, so new files will also be owned bysvnusers
. - Run apache httpd with the
mod_umask
module. It's undocumented, but reasonably simple. First install it (it's not part of a standard apache install). This may entail compiling from source. Then just putLoadModule umask_module /usr/lib/apache2/modules/mod_umask.so
and
umask 0017
somewhere in yourhttpd.conf
(or if you're so lucky as to be running Debian, use the tricks by them: add theLoadModule
to a new file inmods-available
and theumask
to the file insites-available
that takes care of your Subversion repository, then enable them).
Of course, now you still need to enable SSL to make it secure...
