RE: resolution of relative external path for given 'peg' revision

At which URL do you set the ‘svn:externals’ property?

And on which URL does the node have when you perform the update?

The ../../ is applied against the URL the node has at the time of running update/checkout. If that node has a different url then when you tagged it (and that is a problem) you shouldn’t have used a node relative external definition.

Update doesn’t check the revision in which the property was set on the directory to determine which URL to use for resolving relative externals or you would have many other problems

Subject: resolution of relative external path for given 'peg' revision

Hi,

I am not in the list, so please Cc me for any feedback.

I have the following use case that does not work and I think it's a (conceptual) bug with 'pegged' AND 'relative' externals:

- consider the following structure (revision 1)

/proj/lib/a/trunk/

/proj/app/b/trunk/

- now we add a 'pegged' external to check out the lib "a" at its initial revision from within b (yielding revision 2)

proj/app/b/trunk => svn:external := "../../../lib/a/trunk_at_1 <mailto:../../../lib/a/trunk_at_1> a" (that gets resolved to "/proj/lib/a/trunk_at_1 <mailto:proj/lib/a/trunk_at_1> ")

- now I simply move "proj" to "proj2" in the repository (yielding revision 3)

Now doing a checkout of "proj2"s including the external will not work, claiming there was "no /proj2/lib/a/trunk at revision 1". Which is utterly true. But why is SVN looking for that "proj2" path despite me pinning my 'external' to revision "1"? What is the purpose of completing the relative path using any other revision than 'peg', only to fetch the local copy for the 'peg' revision anyway, no matter what revision I specifiy in the parameters of a checkout or an update?

I think this is a misconception. It should be fixed by respecting the 'peg' revision of an 'external' when resolving the actual path, thus getting the path of the attribute owner for 'peg' revision and not for HEAD or whatever was specified to the command.

I am currently not involved as an active developer but I'd offer to become one and provide a patch if that makes sense to anyone.
