logging exceptions in production?

[Juraj Variny]

Hi,

when there is an exception in production mode, all I get is one-line message on the console and nothing in the log file, regardless of log level. Is it possible to enable logging of exception backtraces ?
I only found a hint to install external library: https://groups.google.com/d/topic/turbogears/VFVSMaaQbgY/discussion which is not extant anymore.

Or should I wrap all my code in try blocks and log all exceptions manually?

If you set correct email settings in your production.ini you should get the full traceback per Mail!

In addition to what Moritz said, you absolutely should be getting
tracebacks in your log files. I know that I do. What's probably
killing you, though, is the settings in your .ini file. Understanding
all of the ins and outs of configuring the Python logging module is
not always easy.

Could you post your .ini file for your applicaiton (sanitizing
passwords and other sensitive information, of course!), and I'll help
you figure out why you're not getting the info in your log files.

Thanks!

Well, this is the config. I was in impression that I get no email, but cause TG neglects setting Date header, all error emails ended up in the bottom of my inbox (this should be fixed, too.)

TIA. Juraj

It was Pylons WebError that does not put date into emails, and fix was trivial: https://github.com/Pylons/weberror/pull/4 . So at least I can use the email.
