At the moment all preproduction masters run on preproduction-master.build.mozilla.org server.
Pre-production system has a "managing" master, which runs quality check of the releng repositories.
At the moment the managing master runs at http://preproduction-master.build.mozilla.org:8710 and the corresponding repository is here.
This master runs the following check for each push:
- sets up a virtual environment and installs all needed modules
- runs test-masters.sh
- runs pylint
- generates a coverage report for buildbotcustom and publishes it at http://preproduction-stage.build.mozilla.org/coverage/buildbotcustom/
There are 3 other types of masters running on the same machine:
- scheduler master
- polls Firefox hg repositories with reduced poll interval (6h)
- uses local MySQL database as a backend
- builder master
- has 1 build slave per platform
- tests master
- has 1 test slave per platform
Once a week the managing master recreates virtual environment for all masters listed above, removes all database entries and restarts the servers.
There is a hourly cronjob which scans twistd.log files for unhandled exceptions and emails them to release@ mailing list.
