[wp-hackers] Plugin Upgrade Failing when using Subversion

[Mike Schinkel]

Hi All:

I've just run into a problem with plugin upgrades failing when using Subversion for version control.  Subversion stores a collection of readme files and when the upgrade process tries to delete them it fails to and then fails the upgrade process.  Am I the first person on this list to experience this?  It fails in a very ungraceful way, i.e. basically it just says "Sorry, sux to be you." ;-)

Potential solutions:

1.) Bypass deleting any .svn directory(s) and in that case don't require the plugin directory to be deleted in order to continue the upgrade process.
2.) Remove the read-only attribute and delete the files.
3.) Something else?

I think #1 is most preferable because it doesn't loose the Subversion info and the next check-in will check-in the new plugin info.  Maybe this could be a configuration option, i.e. to do #1 by default or #2 if configured to do so instead?

I need this fixed ASAP so I can do the work to fix it but I've yet to contribute any patches so I don't know the process.
