Monitoring subversion usage

[Jean Lofts <je...@eng.ox.ac.uk>]

Hello All

I'm fairly new to subversion but have a (simple?) question
about monitoring usage.

Each user has a folder at the top level of our single
repository. They only have write access in their own folder.
We are using the Berkeley DB backend.

On a traditional filesystem it's easy for me to monitor how
much disk space each user is consuming and send off an
email if somebody is being too greedy.
Can anybody suggest how I can do something similar with
subversion?

Many thanks

Jean

Well, that's why it's so nice to get commit emails;  they describe 
exactly what got committed.  You could certainly modify your 
email-script to examine and announce the file-sizes of things that got 
added in each commit.  On the other hand, if the email shows a user 
committing a large collection of .mp3 files, that may be enough 
indication.  :-)

You realize that BDB just grows and grows, right?  It never, ever gets 
smaller?  If a user commits a huge file to his repository area, then 
gets scolded and deletes the file, the file still remains in history 
forever.  The database doesn't shrink.

That said, you can certainly write a program to use the svn_fs.h API to 
walk the repository filesystem and add up file-sizes.  I'm just not 
sure that your quota idea makes any sense to enforce anymore.
