Compare Source

==================

Breaking changes

• DatabaseJanitor class now accepts only keyword arguments. (#&#8203;899 <https://github.com/ClearcodeHQ/pytest-postgresql/issues/899>__)

Bugfixes

• Fix the remaining DepcrecationWarning for datetime.datetime.utcnow on Python 3.12. (#&#8203;896 <https://github.com/ClearcodeHQ/pytest-postgresql/issues/896>__)

Deprecations

• Deprecated load parameter on a client fixture.
  Developers are encouraged to either use the load function/parameter
  for process fixture, or create an intermediate fixture placed between client
  and tests themselves to fill in the data. (#&#8203;850 <https://github.com/ClearcodeHQ/pytest-postgresql/issues/850>__)

Features

• Now all sql files used to initialise database for tests, has to be passed as pathlib.Path instance.

  This helps the DatabaseJanitor choose correct behaviour based on parameter. (#&#8203;638 <https://github.com/ClearcodeHQ/pytest-postgresql/issues/638>__)

• Have separate parameters for template database name and database name in DatabaseJanitor.
  It'll make it much clearer to understand the code and Janitor's behaviour. (#&#8203;672 <https://github.com/ClearcodeHQ/pytest-postgresql/issues/672>__)

• Template databases are now created with is_template flag turned on, and not by setting allow_connections to false.

  The allow_connections flag being set to false is used strictly right before we attempt to drop the database. (#&#8203;914 <https://github.com/ClearcodeHQ/pytest-postgresql/issues/914>__)
