Today it's very hard to debug ImportErrors raise inside modules
referenced through a zcml directive, because the ImportError is
swallowed an no traceback comes back to the user. Just a
ConfigurationError: ('Invalid value for', 'class', "Couldn't
import some.class, cannot import name somename")
which doesn't point anywhere useful.
I'd like to modify zope.configuration.config to something like:
try:
mod = __import__(mname, *_import_chickens)
except ImportError, v:
+ if sys.exc_info()[2].tb_next is not None:
+ # ImportError was caused deeper
+ raise
raise ConfigurationError, (
"Couldn't import %s, %s" % (mname, v)
), sys.exc_info()[2]
Instead of the simpler code that was there (this nice trick is by
PJE, and is used ).
Also I need to fix zope.configuration.xmlconfig, today it has a bare
except:
try:
self.context.begin(name, data, info)
except:
if self.testing:
raise
raise ZopeXMLConfigurationError, (
info, sys.exc_info()[0], sys.exc_info()[1]
), sys.exc_info()[2]
Shouldn't it just catch ConfigurationError?
With both changes I get much nicer error report: just a traceback
with the correct info.
