"svn export" forgets svn:externals in local working copies

[Ryan Schmidt <su...@ryandesign.com>]

Hi. We just updated Subversion on our servers from 1.1.4 to 1.2.3 and  
are therefore experiencing this issue:

https://subversion.tigris.org/issues/show_bug.cgi?id=2429

The problem is that since Subversion 1.2.3 (possibly since 1.2.0?),  
if you have a working copy which contains externals definitions, and  
you export that working copy, then the export does not contain the  
external items. If you instead export from the repository URL  
directly, the external items are present.

We have a script which we use to deploy all of our projects, and it  
relies on the now-broken behavior: we have a working copy on the  
production server which the script updates, and then the script  
exports the working copy to another location.

I can confirm the behavior with Subversion 1.2.3 on Gentoo Linux i386  
and also with Subversion 1.3.1 on Mac OS X 10.4.6 PPC.

There seem to be no notes in the bug other than the initial reporting.

Does anybody have any additional information about this problem, or  
suggestions for workarounds? Thinking about it for a moment, I can  
think of the following workarounds:

* svn export the repository URL instead of the working copy. This is  
fine for small projects but we also have some projects approaching  
100MB and the time needed to pull all that over the net for each  
release would be unfortunate, not to mention that we have to pay for  
the bandwidth.

* Write our own svn export routine, which unless I'm mistaken should  
just be:

	cp -RPp working-copy export
	find export -type d -name .svn -print0 | xargs -0 rm -rf

Or apparently (finding my way with rsync here):

	rsync --archive --cvs-exclude working-copy export-tmp
	mv export-tmp/working-copy export
	rmdir export-tmp

Any other ideas?
