Hiya folks,
Now that Python 2.5 is offically out and has introduced "with" blocks
(http://docs.python.org/whatsnew/pep-343.html), I'm wondering if we
(i.e. the module authors) should standardize how DB-API compliant
modules leverage this functionality.
One obvious possibility is that connection and cursor objects could
return themselves in __enter__ and close themselves on __exit__. This
would allow the user to write something like this:
with module.connect(...) as conn:
with conn.cursor() as cur:
# ...
which is much easier to read than the equivalent:
conn = module.connect(...)
try:
cur = conn.cursor()
try:
# ...
finally:
cur.close()
finally:
conn.close()
I've already implemented this behavior for InformixDB in CVS, but if
people have better ideas, I'm definitely open to suggestions.
-Carsten
