Exception not captured

[Miki Tebeka]

Hello All,

Can someone please explain how is the following code fragment possible?
(If you're interested I can place the whole project somewhere).

def checkout(dest, log):
'''Get latest version from SCM

client - SCM client to use
dest - Destination directory
'''
try:
SCM.checkout(de st, log)
except SCMError, e:
raise NightlyError("C heckout")
except Exception, e:
import inspect
file = inspect.getsour cefile(e.__clas s__)
line = inspect.getsour celines(e.__cla ss__)[1]
print "%s:%d" % (file, line)
file = inspect.getsour cefile(SCMError )
line = inspect.getsour celines(SCMErro r)[1]
print "%s:%d" % (file, line)
print SCMError is e.__class__
raise SystemExit

I get to the second "except" clause, and the printout is:
/home/mikit/work/nightly/scm/common.py:3
/home/mikit/work/nightly/scm/common.py:3
False

How is this possible?
Bye.

Some kind of duplicate import, maybe? E.g.:
[color=blue][color=green][color=darkred]
>>> import sys
>>> import inspect
>>> getsource = inspect.getsour ce
>>> del sys.modules["inspect"]
>>> import inspect
>>> getsource is inspect.getsour ce[/color][/color][/color]
False

I suspect you meant to do:

print "SCMError is", e.__class__

The way you have it now, it's printing out the result of the "is"
operator, which tests for identity.
