- Check return value of PyErr_Malloc and set an exception in case of error
- Avoid exposing variables with refcount 0 as connection attributes.
- PyErr_Free guards itself for NULL input
Just compiled! No test run yet and many points to review, marked in the
code.
The patch is largely Martin von Löwis work, simplified after refactoring
in the previous commits and adapted to the new code (as the patch was
originally for Psycopg 2.0.9)
.c files only need to import psycopg.h: it will in turn import
dependencies from Python and libpq and configure.h. psycopg.h should be
the first to be imported, so the basic imports are not required in
the .h's
As a guideline I'm trying to import from the most specific to the most
generic to detect missing imports in the .h's.
We don't do somersaults to ensure people can use snowmen as transaction
ids anyway: it would require passing the connection to xid_ensure and
down below to use the correct encoding.
