The relative URLs being allowed in svn:externals was a huge step
forward. But it still relies on the source path not ever changing.
For example:
/repos/zag foo/bar1
Which is fine as long as "zag" never changes its name.
What if there was some sort of a GUID value for each object, created the
first time that the object is added to the repository, that could then
be used as the source URL?
/repos/GUID:4e1243bd22c66e76c2ba9eddc1f91394e57f9f83 foo/bar1
Which would hopefully track /repos/zag as it changes from /repos/zag to
/repos/zig to /repos/forgreatjustice.
(I suspect this all ties in with the copy/rename issue, which is itself
a rather hairy topic.)
Is this also a moot point if you use the "pegged revision" style of
svn:externals where you prefix the property value with "-r ####"? That
even if "/repos/zag" changes to "/repos/zig" it won't matter because
you're pegging to a revision before the name change occured?
