Thanks much for the link to this script (and thanks to Ben Smith-Mannschott
for writing it) - it looks like it could be very useful.
After much discussion it was decided not to try and do this. Our situation is
this: we currently have our svn:externals set to have a specific
revision number.
This is so that when a developer checks out a certain version of the project
they get the specific version of the externals that goes along with the version
of the project they got. But all the versions prior to when we started
doing this
have no -r specified in svn:externals. So when a user pulls one of these older
versions they get the latest and greatest version of the externals, which often
do not work with the old version of the project. Our plan was to
modify svn:externals
for the old versions to have the appropriate -r specified. Instead we
decided to
deal with this procedurally - the developers were all told that if
they update to a
revision <=n then they need to explicitly update all the externals to the same
revision. It would be better if it was automated, but the thought of
mucking around
with the dump file was just too scary for my manager to accept.
