I may just be doing something wrong here so I apologize if this isn't a real issue, but something is definitely not working correctly.
To start with, I posted this question which Ned answered: http://stackoverflow.com/questions/27363230/python-unittest-with-coverage-report-on-subprocesses/
I changed my
sitecustomize.py to be:
import coverage coverage.process_startup()
... because I didn't want to be running coverage during normal usage. My understanding from the docs is that it shouldn't do anything unless it finds the
COVERAGE_PROCESS_START environment variable. However when I try to kill my program that's running as user
www-data I get the following error:
Error in atexit._run_exitfuncs: Traceback (most recent call last): File "/sites/metrics_dev/env/lib/python3.4/site-packages/coverage/control.py", line 417, in _atexit self.save() File "/sites/metrics_dev/env/lib/python3.4/site-packages/coverage/control.py", line 493, in save self.data.write(suffix=data_suffix) File "/sites/metrics_dev/env/lib/python3.4/site-packages/coverage/data.py", line 91, in write self.write_file(filename) File "/sites/metrics_dev/env/lib/python3.4/site-packages/coverage/data.py", line 131, in write_file fdata = open(filename, 'wb') PermissionError: [Errno 13] Permission denied: '/.coverage.dev.12466.403470'
This indicates that it's trying to write coverage details to a file even though I haven't set the environment variable. Originally I thought this was due to a cached .pyc file in pycache but after deleting that I'm still getting that error message.
