* Py3 migration * Update to Python 3 for CircleCI * Fix auth bugs for python 3 Also fix notifier bug to check for active users * Update notifier exception handling Ignore role:target lookup failures from Iris, since these don't represent problems with the underlying system, just that people have inactive users on-call in the future. * Add get_id param option (#246) * add get_id param option * removed superfluous select and simplified logic * Flake8 typo (#247) * Hide confusing team settings in an advanced dropdown * Fix test fixtures * Add "allow duplicate" scheduler in UI Already in backend, so enable in FE too * Add Dockerfile to run oncall in a container * Move deps into a virtualenv. Run app not as super user. Mimick prod setup by using uwsgi * Fix issue with Dockerfile not having MANIFEST.in and wrong passwords in (#257) config * Update to ubuntu:18.04 and python3 packages and executables * Open config file as utf8 The default configuration file has utf8 characters, and python3 attempts to open the file as ASCII unless an alternate encoding is specified * Switch to the python3 uwsgi plugin * Update print and os.execv statements for python3 Python3 throws an exception when the first argument to os.execv is empty: ValueError: execv() arg 2 first element cannot be empty The module documentation suggests that the first element should be the name of the executed program: https://docs.python.org/3.7/library/os.html#os.execv * Map config.docker.yaml in to the container as a volume ./ops/entrypoint.py has the start of environment variable support to specify a configuration file, but it is incomplete until we update ./ops/daemons/uwsgi-docker.yaml or add environment support to oncall-notifier and oncall-scheduler. This commit allows users to map a specific configuration file in to their container and have it used by all oncall programs. * Convert line endings to match the rest of the project. * Add mysql port to docker configuration * Assume localhost mysql for default config.yaml * Update python-dev package and MySQL root password * Use password when configuring mysql The project has started using a password on the mysql instance. Once password auth is consistently working we can consider extracting the hardcoded password into an env file that is optionally randomly generated on initial startup. * Fix preview for round-robin (#269) * #275 fix for Python3 and Gunicorn load config * Fixed E303 flake8 * Change encoding & collation + test unicode name Co-authored-by: Daniel Wang <dwang159@gmail.com> Co-authored-by: ahm3djafri <42748963+ahm3djafri@users.noreply.github.com> Co-authored-by: TK <tkahnoski+github@gmail.com> Co-authored-by: Tim Freund <tim@freunds.net> Co-authored-by: Rafał Zawadzki <bluszcz@bluszcz.net>
