Don't put too much weight on my interest. I cannot promise to do a lot
because I still have only limited time free....
I hate to see you lose time over this just because I started
commenting on this subject.
I think I will first make a simple approach and build on the code
supplied by Ronaldo Capaverde after converting it to MSSQL and also
making it more configurable for other ADO database connections.
The original code has (in my view) put too much into designtime
component properties. I will most probably change that into regular
If that works out OK I may look at the database end via the audit API
So first test using the parsing of RCS files from Ronaldo Capaverde
but towards a MSSQL database.
Next I will probably test it using ODBC against a SQLite database.
Then switching to getting the info via regular cvs calls rather than
direct access to the RCS files. Have to figure out how to do that in a
good way though. Any ideas how ViewVC did it when they switched from
GNU rcs calls to using the cvsnt cvs.exe?
Finally trying to get the database stuff going via audit API calls (if
at all possible for me). THis would decouple the database knowledge
from the importer.

COM is a pig!
We use COM (or rather DCOM) in our automation software since 2002. It
has caused a lot of grief concerning the handling of the type
libraries and the evolution of those in order not to crash older
versions of our software. Microsoft has failed to make a reasonable
way to version type libraries so that an installer can check that it
does not inadvertently replace a newer tlb with an older one, thus
breaking existing installed applications!
We had to make a dll out of the tlb and include our own versioning
info in that so we can make the installer (still InnoSetup!) do the
Very strange errors can also happen like when a customer had a service
pack for XP installed and the system stopped working. Noone even knew
about the SP at first and we tried in vain to get it going until we
finally found that the SP had changed the fundamental base handling in
Winows of DCOM and RPC. Had to put a strange registry entry in place
to fix that....
And lost about a week's worth of service engineer time on location (of
course half way across the world too). Not funny.
Unfortunately we are now stuck with it...
Had we known at the time we might have designed the whole system
