Subject Re: Excessive Lock/Unlock Traffic
Date Fri, 21 Jul 2006 15:33:21 GMT
I'm pretty sure Mladen didn't intentionally do a 'svn lock/unlock' on each
file. Maybe his IDE did - he can
comment on what commands he used to perform the operation.

However, I don't see any reason for svn to send a mail whenever a file is
locked or unlocked - the
purpose ( AFAIK ) is to allow review and inform people of repository
activity - locking a file
doesn't look like something you would "-1", it's more of an internal svn/dav

Changing a property on all files in a repository is a normal, legal
operation that other
projects may do ( tomcat will probably avoid this in future :-).

If you think svn is correct in sending lock/unlock/proppatch mails for each
individual file ( without at least agreggating them ) - then
it would be good to inform projects on what to expect, how to turn off mail
before doing such changes, or
how to do this kind of changes without locking.
