Solution to have svn managed file-permissions and ownership


From: http://www.abmh.de/en/papers/linux/a...rmissions.html

asvn - svn including file permissions and ownership

If you want to control somethink like /etc with svn you definitely need svn to take care of file permissions. I found this asvn script which works good after I spend some time to sort out all this patch-chaos. I found nowhere an up-to-date version. So I decided to put it up here.

This script was written by Ross Mark (rossm at controllingedge.com.au), I downloaded it from http://svn.collab.net/repos/svn/trun...ient-side/asvn. That I patched it with http://markmail.org/message/rqitgigeh2ep5dsw and made it working. So I hope its going to help you.

Code:

#    This script was written by Ross Mark (rossm at
#    controllingedge.com.au), I (Andreas Hofmeier, http://www.abmh.de/)
#    downloaded it from
#    http://svn.collab.net/repos/svn/trunk/contrib/client-side/asvn. Than
#    I patched it with http://markmail.org/message/rqitgigeh2ep5dsw and
#    made it working. So I hope its going to help you.

#    Description:
#    Archive SVN (asvn) will allow the recording of file types not
#    normally handled by svn. Currently this includes devices,
#    symlinks and file ownership/permissions.
#
#    Every file and directory has a 'file:permissions' property set and
#    every directory has a 'dir:devices' and 'dir:symlinks' for
#    recording the extra information.
#	
#    Run this script instead of svn with the normal svn arguments.
