== Application Description ==
Slavealloc is a client-server application.  The client is [http://hg.mozilla.org/build/puppet-manifests/file/tip/modules/buildslave/files/runslave.py 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 <tt>buildbot.tac</tt> file suitable for use to start buildslave.


The slavealloc server is a implemented as a small Twisted application ([http://hg.mozilla.org/build/tools/file/tip/lib/python/slavealloc 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.
