Application Description
Slavealloc is a client-server application. The client is runslave.py. Communication is via a very basic HTTP request to http://slavealloc.build.mozilla.org/gettac/$slavename, where the response is expected to be a buildbot.tac file suitable for use to start buildslave.
The slavealloc server is a implemented as a small Twisted application (source) which serves the tac generator, a JSON REST interface, and a client-side JavaScript interface.
The same source code also implements a command-line frontend to the REST interface.
Requirements
The server depends on
- MySQL database
- Python
- Twisted
- SQLAlchemy
Development
First, install build/tools in a virtualenv:
cd tools virtualenv sandbox sandbox/bin/pip install -e .
Then you can run the slavealloc daemon locally from the root of the tools repository with a simple:
sandbox/bin/twistd -noy lib/python/slavealloc/contrib/slavealloc-combined.tac
Note that due to what I believe to be a bug in pip, you may need to explicitly install Twisted to get the twistd executable installed:
pip install -U twisted
To set up a fresh database, use
sandbox/bin/slavealloc dbinit -D sqlite:///slavealloc.db
This configuration will use SQLite to access {{{slavealloc.db}}} in the current directory. You can hack on the static web content while the daemon is running.
Production Instance
Deployment Requests
To request an update to the code for slavealloc, file a bug in "Infrastructure & Operations - WebOps: IT-Managed Tools" with the following information (bugzilla template):
- Name of the cluster ("releng cluster") pre-entered
- Short name of the site (e.g., "slavealloc") pre-entered
- Revision to update to REVISION_NUMBER in template
- Any limitations on timing ("not before", etc.) TIME_CRITERIA in template
- Link to the relevant mana page pre-entered
