Remove threadlocal engine strategy, engine strategies pool threadlocal 2019-07-16T02:48:47+00:00 Mike Bayer mike_mp@zzzcomputing.com 2019-04-11T18:21:13+00:00 dfb20f07d8796ec27732df84c40b4ce4857fd83b The "threadlocal" execution strategy, deprecated in 1.3, has been removed for 1.4, as well as the concept of "engine strategies" and the ``Engine.contextual_connect`` method. The "strategy='mock'" keyword argument is still accepted for now with a deprecation warning; use :func:`.create_mock_engine` instead for this use case. Fixes: #4632 Change-Id: I8a351f9fa1f7dfa2a56eec1cd2d1a4b9d65765a2 (cherry picked from commit b368c49b44c5716d93c7428ab22b6761c6ca7cf5)

Move initialize do_rollback() outside of the dialect 2019-05-10T01:50:59+00:00 Matthew Wilkes git@matthewwilkes.name 2019-05-09T22:04:35+00:00 f601791a914d3181252493800871c458ad6c46d1 Moved the "rollback" which occurs during dialect initialization so that it occurs after additional dialect-specific initialize steps, in particular those of the psycopg2 dialect which would inadvertently leave transactional state on the first new connection, which could interfere with some psycopg2-specific APIs which require that no transaction is started.

Add deprecation warnings to all deprecated APIs 2019-01-23T23:10:06+00:00 Mike Bayer mike_mp@zzzcomputing.com 2018-12-21T03:05:36+00:00 4c2c2c40fde17c85013e00a6f3303a99e2b32c12 A large change throughout the library has ensured that all objects, parameters, and behaviors which have been noted as deprecated or legacy now emit ``DeprecationWarning`` warnings when invoked. As the Python 3 interpreter now defaults to displaying deprecation warnings, as well as that modern test suites based on tools like tox and pytest tend to display deprecation warnings, this change should make it easier to note what API features are obsolete. See the notes added to the changelog and migration notes for further details. Fixes: #4393 Change-Id: If0ea11a1fc24f9a8029352eeadfc49a7a54c0a1b

Run black -l 79 against all source files 2019-01-06T17:34:50+00:00 Mike Bayer mike_mp@zzzcomputing.com 2019-01-06T06:14:26+00:00 1e1a38e7801f410f244e4bbb44ec795ae152e04e This is a straight reformat run using black as is, with no edits applied at all. The black run will format code consistently, however in some cases that are prevalent in SQLAlchemy code it produces too-long lines. The too-long lines will be resolved in the following commit that will resolve all remaining flake8 issues including shadowed builtins, long lines, import order, unused imports, duplicate imports, and docstring issues.

Add LIFO for connection pooling 2018-09-19T01:58:02+00:00 Taem Park wwwee98@gmail.com 2018-08-21T14:54:45+00:00 b64a3dd87a4204ce6d4f2793a7a3f7fbf72eb01f Added new "lifo" mode to :class:`.QueuePool`, typically enabled by setting the flag :paramref:`.create_engine.pool_use_lifo` to True. "lifo" mode means the same connection just checked in will be the first to be checked out again, allowing excess connections to be cleaned up from the server side during periods of the pool being only partially utilized.

Allow multiple plugin names 2018-02-13T20:28:11+00:00 Mike Bayer mike_mp@zzzcomputing.com 2018-02-13T20:11:53+00:00 15ea75981305fdad8286f6803671b864ccda13f2 The :class:`.URL` object now allows query keys to be specified multiple times where their values will be joined into a list. This is to support the plugins feature documented at :class:`.CreateEnginePlugin` which documents that "plugin" can be passed multiple times. Additionally, the plugin names can be passed to :func:`.create_engine` outside of the URL using the new :paramref:`.create_engine.plugins` parameter.
