Hi All,

Has anyone had any success with overriding Houdini's python sys.excepthook?

I'm using it for automated error reporting for our pipeline scripts.

houdini doesn't object if i pass sys.exepthook a custom function, but it never gets called.

cheers,

Hi there,

having the same issue here.

We would like to use Raven/Sentry for Error-Logging (https://github.com/getsentry/raven-python) [github.com]
which is build around sys.excepthook

basically:
def handle_exception(exc_type, exc_value, exc_traceback):
	print "there was a issue"
sys.excepthook = handle_exception
print 1 / 0

in any “normal” python-shell this just prints
"there was a issue".
in the houdini-python-shell I still get the usual Traceback
Traceback (most recent call last):
  File "<console>", line 1, in <module>
ZeroDivisionError: integer division or modulo by zero
is this expected? Am I'm missing something here?


cheers

Loqy,

the last comms i had with sidefx about this was:

I was told that Houdini's Python shell (in the GUI) uses Python's code.InteractiveInterpreter class which, for whatever reason, doesn't use sys.excepthook. The following code will change it to use sys.excepthook:

import sys
import houdiniInterpreter

def showtraceback(self):
sys.excepthook(*sys.exc_info())

houdiniInterpreter.HoudiniConsole.showtraceback = showtraceback

However, for other uncaught exceptions, like shelf tools, there's currently no way to customize the exception callback. There is an RFE submitted for this

in summary, you can override excepthook in the python shell window, but not shelf tools.

Hey!

I know this has been many years ago, but maybe there has been an update to this, since we would also like to do automatic error reporting

Is there nowadays a way to override exception handling basically for any python code executed within Houdini. It could be within
* Shelftools
* Python nodes
* HDAmodules
* Node/Parm callbacks
* ...


Hooking into
houdiniInterpreter.HoudiniConsole.showtraceback
for the Python shell worked, but no success so far for any of the other topics.

I also tried overriding the following:
sys.excepthook
houdiniInterpreter.code.sys.excepthook
houdiniInterpreter.sys.excepthook

Any input would be appreciated!

Cheers!
