galaxy package

Galaxy root package – this is a namespace package.

galaxy.app module

class galaxy.app.UniverseApplication(**kwargs)[source]

Bases: galaxy.config.ConfiguresGalaxyMixin

Encapsulates the state of a Universe application

galaxy.config_watchers module

class galaxy.config_watchers.ConfigWatchers(app)[source]

Bases: object

Contains ToolConfWatcher, ToolWatcher and ToolDataWatcher objects.

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, get_response=False, kwargs=None)[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, get_response=False, routing_key='control.*', kwargs=None)[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. Set noop_self to True to not run task for current process. Set get_response to True to wait for and return the task results as a list.

class galaxy.queue_worker.ControlTask(queue_worker)[source]

Bases: object

control_queues
exchange

on_response(message)[source]

galaxy.queue_worker.reconfigure_watcher(app, **kwargs)[source]
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.rebuild_toolbox_search_index(app, **kwargs)[source]
galaxy.queue_worker.reload_job_rules(app, **kwargs)[source]
galaxy.queue_worker.job_rule_modules(app)[source]
galaxy.queue_worker.admin_job_lock(app, **kwargs)[source]
class galaxy.queue_worker.GalaxyQueueWorker(app, task_mapping=None)[source]

Bases: kombu.mixins.ConsumerProducerMixin, 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.

__init__(app, task_mapping=None)[source]
send_control_task(task, noop_self=False, get_response=False, routing_key='control.*', kwargs=None)[source]

galaxy.queues module

All message queues used by Galaxy

galaxy.queues.all_control_queues_for_declare(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.

galaxy.queues.control_queues_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]
