Description

The Import Hook PEP provides ways to get the sourcecode of modules imported using an import hook like the zipimporter or others. Django does not use this currently. But it would be a good thing if it would do because python eggs, and many template engines use it.

I don't have a patch yet but some sourcecode from the colubrid package that provides this: ​http://trac.pocoo.org/browser/colubrid/trunk/colubrid/debug.py

Ramiro, #3527 is about "better debug traceback with code executing". Did you confuse it with another ticket?

Sorry, I totally missed the point. I thought this ticket was also asking for the integration of fancy stack traces
with more debugging info about the modules. Please disregard my comment.

Keywords: debug __loader__ added
Summary: __loader__ support for debuggin module → __loader__ support for debugging module
Triage Stage: Unreviewed → Design decision needed

comment:6 by Armin Ronacher, 18 years ago

Ramiro: Not, not code execution. Just the ability of seeing the sourcecode of eggs, zipfiles imported etc. Unfortunately django doesn't use linecache but file() directly, so that this doesn't work out of the box.

comment:7 by Armin Ronacher, 18 years ago

I created a patch now. Note on the additional escapes: it's likely that there is a value called "<module>" or "<unknown>" so it's better to escape that.
