Cool. Glad to know I'm not completely off the mark from the beginning :)

Could you point me at (or explain) this concept? I had a search through
the mailing list before I posted this, but I didn't find anything that
seemed appropriate.

(Er, that should read "bugtraq:clsid" or "bugtraq:progid"...)

Hmmm. In our situation, that's not a problem, because we use SSPI. I can
use either the currently logged-in user, or I can rely on integrated
NTLM auth with the issue tracker to give me the correct issues. Worst
case (I guess) the COM object would have to prompt for (and potentially
cache) the credentials. This would be on per-repos basis, so this would
have to be one of the parameters to the COM interface.

If implemented the way I imagine, this is a problem (an implementation
detail, rather than an interface detail) for the COM object to handle,
rather than for TortoiseSVN.

My plan was to define the COM interface and requirements, implement the
client-side stuff in TortoiseProc, and leave the rest as an "exercise
for the reader". I might do an example implementation against Trac (once
the XmlRpc plugin is brought up-to-date with Trac-v0.11, probably).
We're not going to be using Trac at work, but I've started using it on
some personal projects.

My plan was to implement something useful to us internally, but generic
enough that the patches could go back into TortoiseSVN core, to save us
the overhead of building TortoiseSVN every time you guys drop a new
release. Hence COM.

Thanks. I'm not so sure that the username thing is as big a problem as
you make out.

That's probably because I'm a little blinkered by only ever using
Subversion and TortoiseSVN on closed-source stuff, and not having to
think about the open-source side. I'd definitely appreciate any insight
you could offer into how this feature would be used differently.

Yeah. This depends on the API to the issuetracker. If it's a web service
(e.g. XML RPC or SOAP), then I can run the call in a background thread
and cancel it if it's taking too long. If it's something else, this
needs more thought.

OK. I'll get TortoiseProc built and spike something out in the next
week. That'll give me an idea of direction, and then I can write some
slightly more formal documentation for my proposal.

Cheers,
Roger.
