2.3.0

This release includes two important updates:

1. An Update update to task-collection configuration variables and logic.
2. The first released version of the experimental SSH features.

Re: task-collection configuration, we now support two main use cases:

1. When running a production instance (including on a SLURM cluster), you should set e.g. FRACTAL_TASKS_PYTHON_DEFAULT_VERSION=3.10, and make sure that FRACTAL_TASKS_PYTHON_3_10=/some/python is an absolute path. Optionally, you can define other variables like FRACTAL_TASKS_PYTHON_3_9, FRACTAL_TASKS_PYTHON_3_11 or FRACTAL_TASKS_PYTHON_3_12.

2. If you leave FRACTAL_TASKS_PYTHON_DEFAULT_VERSION unset, then only the Python interpreter that is currently running fractal-server can be used for task collection.

WARNING: If you don't set FRACTAL_TASKS_PYTHON_DEFAULT_VERSION, then you will only have a single Python interpreter available for tasks (namely the one running fractal-server).

• API:
  • Introduce api/v2/task/collect/custom/ endpoint (#1607, #1613, #1617, #1629).
• Task collection:

  • Remove TaskCollectStatusV2 and get_collection_data internal schema/function (#1598).
  • Introduce CollectionStatusV2 enum for task-collection status (#1598).
  • Reject task-collection request if it includes a wheel file and a version (#1608). SSH features:
  • Introduce fractal_server/ssh subpackage (#1545, #1599, #1611).
  • Introduce SSH executor and runner (#1545).
  • Introduce SSH task collection (#1545, #1599, #1626).
  • Introduce SSH-related configuration variables (#1545).
  • Modify app lifespan to handle SSH connection (#1545).
  • Split app/runner/executor/slurm into sudo and ssh subfolders (#1545).
  • Introduce FractalSSH object which is a wrapper class around fabric.Connection object. It provides a lock to avoid loss of ssh instructions and a custom timeout (#1618)
• Dependencies:
  • Update sqlmodel to ^0.0.19 (#1584).
  • Update pytest-asyncio to ^0.23 (#1558).

2.2.0

This release streamlines options for the Gunicorn startup command, and includes two new experimental features.

• --worker-class fractal_server.gunicorn_fractal.FractalWorker
• --logger-class fractal_server.gunicorn_fractal.FractalGunicornLogger

NOTE 2: A new experimental local runner is available, which uses processes instead of threads and support shutdown. You can try it out with the configuration variable FRACTAL_BACKEND_RUNNER=local_experimental

NOTE 3: A new PostgreSQL database adapter is available, fully based on psycopg3 (rather than pyscopg2+asyncpg). You can try it out with the configuration variable DB_ENGINE=postgres-psycopg (note that this requires the pip install extra postgres-psycopg-binary).

2.0.6
