Support for SVN repository on a UNC path on Windows

[morphiend@…]

While setting up a Trac installation a year ago, I ran into a problem where my SVN repository was stored on a UNC accessible path on a Windows-based Apache system. In other words, I was running Trac on Apache for Windows, with the python module for Apache. Our SVN repository was stored on a separate network drive and only accessible via a UNC path.

At the time I was using Trac 0.11.x (not sure of the revision, and I no longer operate that system).

The problem is due to SubversionRepository __init__ not handling the UNC slashes properly. When the path is fixed by converting the '\'\' to '\' the UNC slashes were being transformed to just '\' instead of staying '\'\'. I corrected this by adding splitunc() call before the replace and only performing the replace on the non-UNC portion of the path.

I've attached a diff patch making the similar change to the latest version from the 0.12 trunk, as well as the original modified version from my 0.11 installation.

Interesting!

But please have a look at TracDev/SubmittingPatches, we prefer to get submissions as patches instead of whole files, as this makes it much easier to see the changes from the ticket and comment on it.

One thing I can already comment on: splitunc is not available on Unix, so you should either make the code platform dependent (if os.name == 'nt':) or add a trac.util.compat.splitunc utility function that encapsulate this.

No fixup in one year, unscheduling.

If someone is interested by the feature, please provide a patch as suggested above.

Revised patch: t9208.diff​ for 1.0-stable.

I get weird behavior of trac-admin. The 2 backslash character in UNC path is converted to 3 backslash characters. Even though the behavior, the patch works well for UNC path in repository browser, file view and blame view.
