6.2.0

New features

• Add new safir.uws and safir.arq.uws modules that provide the framework of an IVOA Universal Worker Service implementation.
• Add new safir.testing.uws module that provides a mock UWS job runner for testing UWS applications.
• safir.arq is now available as a separate PyPI package, safir-arq, so that it can be installed in environments where the full Safir dependency may be too heavy-weight or conflict with other packages. The safir[arq] dependency will continue to work as before (by installing safir-arq behind the scenes).
• Add new abort_job method to instances of safir.arq.ArqQueue, which tells arq to abort a job that has been queued or in progress. To successfully abort a job that has already started, the arq worker must enable support for aborting jobs.
• Add new utility function safir.arq.build_arq_redis_settings, which constructs the RedisSettings object used to create an arq Redis queue from a Pydantic Redis DSN.
• Add new safir.arq.WorkerSettings class that models the acceptable parameters for an arq WorkerSettings object or class that Safir applications have needed.
• Add new safir.pydantic.SecondsDatetime and safir.pydantic.HumanDatetime types for use in Pydantic models. These behave the same as datetime.timedelta fields but use custom validation. Both support a stringified number of seconds as input, and the latter also supports the interval strings parsed by safir.datetime.parse_timedelta.
• Add new types safir.pydantic.EnvAsyncPostgresDsn and safir.pydantic.EnvRedisDsn, which validate PostgreSQL and Redis DSNs but rewrite them based on the environment variables set by tox-docker. Programs using these types for their configuration will therefore automatically honor tox-docker environment variables when running the test suite. EnvAsyncPostgresDsn also enforces that the scheme of the DSN is compatible with asyncpg and the Safir database support.
• Add the decorator safir.database.retry_async_transaction, which retries a function or method a configurable number of times if it raises a SQLAlchemy exception from the underlying database API. This is primarily intended to retry database operations aborted due to transaction isolation.
• safir.database.create_database_engine now accepts the database URL as a Pydantic Url as well as a str.
• Allow the Slack webhook URL argument to SlackWebhookClient and SlackRouteErrorHandler to be given as a Pydantic SecretStr instead of a str. This simplifies code in applications that get that value from a secret.

Other changes

• Safir is now built with nox instead of tox.
