Feature request

we are currently in the process of implementing subversion on our site and I have found out
it lacks one feature I'd really love to use: relative local paths for svn:externals.

I already started a discussion about such a feature over in the user@ mailing list, and
after a little discussion I got the suggestion to write about my wish here and start a
discussion here.

I know that there are other possible solutions for my problem, but none of those seems to
have the elegancy and simplicity a svn:externals based solution would have! They're either
failure prone (user errors) or would require to use OS level commands/techniques which are
Unfamiliar/strange to normal users here which wouldn't increase trust in a SCM solution at

Here's what I'd like to do:

Given the following directory structure (on Windows):


where each Project directory contains one working copy and relies also on files from CommonFiles
and all of those projects and CommonFiles are from the same repository.

I'd like to be able to specify on Project1 ../CommonFiles as local path of the svn:externals
property. I can understand the security concerns raised over in user@, but for this the feature
should either

a) have a global switch in the client to disallow usage of ../ completely
b) have the possibility to specify a list of "trusted" domains/URL which may contain ../ paths
   and for all other repositories ../ as local path for svn:externals would be illigal
c) A combination of a) and b) so you can switch it off even if a "trusted" list exists

I don't mind a) or b) either would be fine with me.

Another security meassure could be built in I'd be ok with as well: limit relative local
svn:external paths to one single hierarchy level: ../CommonFiles would be allowed but
../../ would be illegal. So for my example nothing could leave d:\Source with that limit.

I hope my wish has been well enough written to be understandable. If not feel free to
contact me for further clarifications.

Best regards

Markus Humm
