Sorry that this was left with unanswered questions for so long...

The main thing to read would be this:

  https://wiki.samba.org/index.php/Contribute

It links to some other pages that are useful.

README.Coding.md at the top of the Samba tree is worth reading.

If you're only working on CTDB then you can ./configure and make
within the ctdb/ subdirectory.

In that case tests/README is worth a scan.

For the work on "ctdb dbstatistics" that you were proposing you would
probably want to add some tests in tests/UNIT/tool/.  I notice that we
don't currently have any tests for "ctdb dbstatistics" there.

That would actually involve implementing CTDB_CONTROL_GET_DB_STATISTICS
in tests/src/fake_ctdb.c.  One implementation would be to add
reading of canned data when fake ctdbd starts, as occurs with quite a
few other controls.

peace & happiness,
martin
