Constraint Failed on update to externals

[Steven Newson <st...@gmail.com>]

Hi,

I found a reference to someone having this problem in 2011, but there
doesn't appear to have been any response or fix. Sorry if this is a repost
or is already being investigated.

I have a path within a Subversion 1.4.4 server (with a 1.7.7 client) which
has an external:

http://svn.mycompany.co.uk/
  |--> /my-repo/src
        |--> build-resources [ points to
http://svn.mycompany.co.uk/my-repo/build-resources ]

I'm moving the external to a different location:
https://othersvn.mycompany.co.uk/new-repo/build-resources

However, after I commit this, anyone who updates the directory gets the
following error:

External failed: my-repo\src\external
Error: sqlite: constraint failed
Error: sqlite: EXTERNALS.def_repos_relpath may not be NULL

The external is updated correctly and the local copy seems to be OK, so
this error is not a blocker. However, I'd prefer not to get the error in
the first place, particularly as I update externals fairly often.

This doesn't happen if the external is on the same repository as the
parent.

Steps to reproduce:

1. Create a directory in subversion (mkdir blah; svn add blah; svn commit
blah)
2. Add and commit an external pointing at some other directory in the same
repository (svn ps svn:externals ...; svn ci)
3. Edit and commit the external to point at any folder in a different
repository (svn ps svn:externals ...)
4. Update the directory (svn up)

You'll get the error on the last step.

Steve.
