Traceback (most recent call last):
File "/home/ike/mitx_all/python/local/lib/python2.7/site-packages/gunicorn/workers/sync.py", line 33, in run
client, addr = self.socket.accept()
File "/usr/lib/python2.7/socket.py", line 202, in accept
sock, addr = self._sock.accept()
error: [Errno 11] Resource temporarily unavailable
* cleaned up error module:
- only one template
- save error message in xml and reload
* better display of problem definition and metadata to staff
* save error messages as string, not exception objects.
* call error tracker when needed
* remove duplicate logging--just add info and re-raise
* xml modulestore uses error tracker to capture load errors
* add unstyled list of import errors to courseware homepage!
* simplify logic--tracker just tracks errors. Trackers should not raise,
and are not be responsible for logging.
* adapted code to use trackers.
* Started cleanup of error handling code:
- if need to add info and re-raise, just do that. No logging.
- if working around a problem, log and track as needed.
