Re: Microsoft's SCC interface

Having done some proprietary work with the SCC API in the past, the key is
that using the SCC lets you integrate into the Microsoft Toolset. As with
anything, over time it's become the defacto version control interface into
many tools. Accesibility to all the tools that use the SCC API would be the
big win for Subversion for it to gain corporate acceptance.

Since it provides only about 12 basic functions (checkin / checkout /
undocheckout, etc..) the problem of mapping what those mean is somewhat
mitigated. It does help as well that Subversion thinks about versioning
directories, which CVS did not. But the lack of openness of the SCC means
having to decide if it's ok to have closed boundary layer between Microsoft
and Subversion which is what the CvsScc work was all about.

Using the MS COM interfaces won't get you integrated into the toolsets, only
into the SourceSafe object model, which is not where you want to go. Having
heard mention of having Subverion COM interfaces would provide the
equivalent access to Subversion. It would be cool if I could replace my
build scripts which use SourceSafe by changing the COM interface code to
Subversion.
