Bases: object

Shared code for configuring Galaxy-like app objects.

wait_for_toolbox_reload(old_toolbox)[source]

galaxy.main module

Entry point for starting Galaxy without starting as part of a web server.

Example Usage: Start a job/workflow handler without a web server and with a given name using.

galaxy-main –server-name handler0

Start as a daemon with (requires daemonized - install with ‘pip install daemonize’):

galaxy-main -d –daemon-log-file=handler0-daemon.log –pid-file handler0.pid –server-name handler0

In daemon mode logging of Galaxy (as opposed to this script) is configured via a loggers section in Galaxy’s ini file - this can be overridden with sensible defaults logging to a single file with the following:

galaxy-main -d –server-name handler0 –daemon-log-file=handler0-daemon.log –pid-file handler0.pid –log-file handler0.log

This can also be used to start Galaxy as a uWSGI mule, e.g. for job handling:

uwsgi … –py-call-osafterfork –mule=lib/galaxy/main.py –mule=lib/galaxy/main.py –farm=job-handlers:1,2

The –py-call-osafterfork allows for proper shutdown on SIGTERM/SIGINT.

galaxy.queue_worker module

Galaxy control queue and worker. This is used to handle ‘app’ control like reloading the toolbox, etc., across multiple processes.

galaxy.queue_worker.send_local_control_task(app, task, kwargs={})[source]

This sends a message to the process-local control worker, which is useful for one-time asynchronous tasks like recalculating user disk usage.

galaxy.queue_worker.send_control_task(app, task, noop_self=False, kwargs={})[source]

This sends a control task out to all processes, useful for things like reloading a data table, which needs to happen individually in all processes.

galaxy.queue_worker.create_panel_section(app, **kwargs)[source]

Updates in memory toolbox dictionary.

galaxy.queue_worker.reload_tool(app, **kwargs)[source]
galaxy.queue_worker.reload_toolbox(app, **kwargs)[source]
galaxy.queue_worker.reload_data_managers(app, **kwargs)[source]
galaxy.queue_worker.reload_display_application(app, **kwargs)[source]

Bases: kombu.mixins.ConsumerMixin, threading.Thread

This is a flexible worker for galaxy’s queues. Each process, web or handler, will have one of these used for dispatching so called ‘control’ tasks.

galaxy.queues module

All message queues used by Galaxy

galaxy.queues.all_control_queues_for_declare(config, application_stack)[source]

For in-memory routing (used by sqlalchemy-based transports), we need to be able to build the entire routing table in producers.

Refactor later to actually persist this somewhere instead of building it repeatedly.

galaxy.queues.control_queue_from_config(config)[source]

Returns a Queue instance with the correct name and routing key for this galaxy process’s config

galaxy.queues.connection_from_config(config)[source]

galaxy.version module
