galaxy.di module

Dependency injection framework for Galaxy-type apps.

class galaxy.di.Container(container: Optional[Container] = None, log_undefined_deps: Union[bool, Logger] = False)[source]

Bases: Container

Abstraction around lagom to provide a dependency injection context.

Abstractions used by Galaxy should come through this interface so we can swap out the backend as needed. For instance https://punq.readthedocs.io/en/latest/ containers look very nice and would allow us to also inject by name (e.g. for config variables for instance).

resolve_or_none(dep_type: Type[T]) → Optional[T][source]

Resolve the dependent type or just return None.

If resolution is impossible assume caller has a backup plan for constructing the desired object. Used to construct controllers that may or may not be resolvable (some have upgraded but legacy framework still works).

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

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

__init__(queue_worker)[source]
property connection
property control_queues
property exchange
property declare_queues
on_response(message)[source]
send_task(payload, routing_key, local=False, get_response=False, timeout=10)[source]
galaxy.queue_worker.reconfigure_watcher(app, **kwargs)[source]

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

Bases: ConsumerProducerMixin, 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]
send_local_control_task(task, get_response=False, kwargs=None)[source]

shutdown()[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) → Optional[Connection][source]

galaxy.structured_app module

Typed description of Galaxy’s app object.

class galaxy.structured_app.BasicSharedApp(container: Optional[Container] = None, log_undefined_deps: Union[bool, Logger] = False)[source]

Bases: Container

Stripped down version of the app shared between Galaxy and ToolShed.

Code that is shared between Galaxy and the Tool Shed should be annotated as using BasicSharedApp instead of StructuredApp below.

class galaxy.structured_app.StructuredApp(container: Optional[Container] = None, log_undefined_deps: Union[bool, Logger] = False)[source]

Bases: MinimalManagerApp

Interface defining typed description of the Galaxy UniverseApplication.

Ideally nothing that depends on StructuredApp should require StructuredApp so we can have a clean import dag. This will require setting up a lot more distinction between interfaces and implementations in Galaxy though. In the meantime, for imports that would bring in StructuredApp if properly type (cyclical imports), we’re just setting the class attributes to Any.
