builder - scheduling and executing jobs
This consists of three programs, a worker, a server, and a client. The single server contains a queue of jobs, which are consumed by a worker. Any number of worker can be connected to the server. The client can modify the schedule: add/remove/modify jobs, also observe a concrete job.
The server keeps persistent state of the job queue (so restarts / crashes are dealt with). A worker connects, provides some information about itself, and then waits for a job. Once a job is read and accepted, it is executed by the worker. Resulting artifacts can be transferred by the client to the server.
The client has the ability to schedule jobs at regular intervals - similar to crontab - but workers are usually executed in sandboxes/ jailed environments.
Handled and unhandled error conditions:
worker execution fails (timeout, restart, killed): not handled, but server has a timeout
worker execution gets a signal: reported to server
worker can't write job data files -> failure is captured and reported
worker can't read job output -> logged to client's console (without artifacts gathered)
worker errors when submitting console output -> ignored
worker fails communication with server -> job is ignored (the server is responsible for restarting)
A templating mechanism is available, look for orb-build.template
as examples. Currently FreeBSD, Debian and Ubuntu are supported, and a repository that receives jobs is live at https://builds.robur.coop/
