Well Zopeists - I stuck my neck out on the postgres-hackers list late last week, and said I'd take a look at whiping the postgres DA into shape to work with Zope2. This involved modifying the PyGreSQL pgmodule source (wrapping calls to the backend with Py_START_ALLOW_THREADS and PY_END_ALLOW_THREADS macros), as well as the DB class inside ZPyGreSQLDA. Well, I think I've at least got it limping along, at Level 2, using the THUNKED_TM 'Kludge of the Century'. I chose to pass the Zope transaction points on through to the Postgres backend, initiating and ending transactions via the _begin, and _finish calls. Hope this is how it's supposed to work. I get what looks to be the correct set of lines in my postgres logs. It all seems to work in my hands, but this is my first attempt at working with threads, and I've written very little Python, besides ;-) So, I need help with suggestions on how to test everything. For this, I mean formal regression-type tests, at the python module interface level, both inside and outside Zope, rather than end-user, plug it in and see if it works for me testing. Anyone?
