gravity 1.2.4

Overview

Modern Galaxy servers run multiple disparate processes: gunicorn for serving the web application, celery for asynchronous tasks, tusd for fault-tolerant uploads, standalone Galaxy processes for job handling, and more. Gravity is Galaxy’s process manager, to make configuring and running these services simple.

Installing Gravity will give you two executables, galaxyctl which is used to manage the starting, stopping, and logging of Galaxy’s various processes, and galaxy, which can be used to run a Galaxy server in the foreground.

Quick Start

$ pip install gravity

$ . ./.venv/bin/activate
$ galaxyctl --help
Usage: galaxyctl [OPTIONS] COMMAND [ARGS]...

• Converted CLI from argparse to click.

• Stole ideas and code from planemo in general.

• Improve the AttributeDict so that it can have “hidden” items (anything that starts with a _) that won’t be serialized. Also, it serializes itself and can be created via deserialization from a classmethod. This simplifies using it to persist state data in the new GravityState subclass.

0.8.3

• Merge galaxycfg and galaxyadm commands to galaxy.

0.8.2

• Allow for passing names of individual services directly to supervisorctl via the start, stop, and restart methods.

• Fix a bug where uWSGI would not start when using the automatic virtualenv install method.

0.8.1

• Version bump because I deleted the 0.8 files from PyPI, and despite the fact that it lets you delete them, it doesn’t let you upload once they have been uploaded once…

0.8

• Add auto-register to galaxy start if it’s called from the root (or subdirectory) of a Galaxy root directory.

• Make galaxycfg remove accept instance names as params in addition to config file paths.

• Use the same hash generated for an instance name as the hash for a generated virtualenv name, so virtualenvs are more easily identified as belonging to a config.

• Renamed from galaxyadmin to gravity (thanks John Chilton).

0.7

• Added the galaxyadm subcommand graceful on a suggestion from Nicola Soranzo.

• Install uWSGI into the config’s virtualenv if requested.

• Removed any dependence on Galaxy and eggs.

• Moved project to its own repository from the Galaxy clone I’d been working from.

Older

• Works in progress as part of the Galaxy code.
