Implementing my own GDM

[Guenther Sohler]

We use subversion for version control of Cadence Databases and it would be
nice, if we could integrate it more into cadence.
I can activate it, when we set the DMTYPE to "svn" in the cdsinfo.tag.

Then cadence looks for a shared object file called libgdmsvn_sh.so
which i can create. But we do not know what to exactly put inside.
We were able to guess some structures like defined symbols like

gdmsvnWrapFuncs

and some of its members but i am curious if there exist official
documentation about that

There *is* documentation available. You just have to pay Cadence a
license fee to get it. I personally feel that Cadence should open up
this spec. However, there is likely difficulty for Cadence in that
their business partners (Synchronicity) would lose a lot of money.

Supposedly, you can get by with the libgdmsvn_sh.so always returning
nil and then writing all your functions using skill hooks. That is
what ICManage did in order to integrate Perforce.

Actually, they have a true GDM integration as far as I know...

To do a GDM integration is actually a lot more work than it might initially
appear, and in practice very few people have done it as a result. Because of
that, making the API entirely open is a lot of work in terms of documentation,
testing, and so on, and it's not worth the bang for the buck (in my opinion;
this is not the view of my employer).

Andrew.
