* Remove threadlocal engine strategy, engine strategies pool threadlocalMike Bayer2019-07-151-160/+0
| | | | | | | | | | | | 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)
* Add deprecation warnings to all deprecated APIsMike Bayer2019-01-231-4/+15
| | | | | | | | | | | | | | | 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

* Post black reformattingMike Bayer2019-01-061-4/+5
| | | | | | | | | | | | | Applied on top of a pure run of black -l 79 in I7eda77fed3d8e73df84b3651fd6cfcfe858d4dc9, this set of changes resolves all remaining flake8 conditions for those codes we have enabled in setup.cfg. Included are resolutions for all remaining flake8 issues including shadowed builtins, long lines, import order, unused imports, duplicate imports, and docstring issues. Change-Id: I4f72d3ba1380dd601610ff80b8fb06a2aff8b0fe
* Run black -l 79 against all source filesMike Bayer2019-01-061-20/+30
| | | | | | | | | | | | | | 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.

* Better hide engine passwordValery Yundin2017-01-161-1/+1
| | | | | | | | | | Avoid putting engine password in the exception message in `MetaData.reflect` (since exception messages often appear in logs). Use the same redacted `__repr__` implementation in `TLEngine` as in its base class `Engine` Change-Id: Ic0a7baea917a9c8d87dffdd82ef566673ab08e02 Pull-request: https://github.com/zzzeek/sqlalchemy/pull/327

* - simplify the "noconnection" error handling, settingMike Bayer2014-12-081-1/+1
| | | | | | | _handle_dbapi_exception_noconnection() to only invoke in the case of raw_connection() in the constructor of Connection. in all other cases the Connection proceeds with _handle_dbapi_exception() including revalidate.
* - adjust _revalidate_connection() again such that we pass a _wrap=FalseMike Bayer2014-12-051-1/+4
| | | | | | | | | | to it, so that we say we will do the wrapping just once right here in _execute_context() / _execute_default(). An adjustment is made to _handle_dbapi_error() to not assume self.__connection in case we are already in an invalidated state further adjustment to 0639c199a547343d62134d2f233225fd2862ec45, 41e7253dee168b8c26c49, #3266

* - some doc reorgMike Bayer2011-03-171-2/+2
| | | | | | | | | | - change engine.Connection to _connection_cls so sphinx doesn't get upset - globally add "." to all :class:`Foo` - start naming sections that are mostly docstrings "API Documentation - blah blah" - move some ad-hoc docstrings into "API" sections, there is some inconsistency here and it may be that we just have to leave it that way - add "internals" rsts to core, orm, I'm not super thrilled how these look but they are targeted by some of the public api docs, users typically become aware of these anyway
* - rename EngineEvents to ConnectionEventsMike Bayer2011-02-171-11/+1
| | | | | | | | - simplify connection event model to be inline inside Connection, don't use ad-hoc subclasses (technically would leak memory for the app that keeps creating engines and adding events) - not doing listen-per-connection yet. this is closer. overall things are much simpler now (until we put listen-per-connection in...)

| | | | | | | | | object. this leaves the original Event class alone so sphinx documents it. this is all a mess right now but the pool/engine tests are working fully at the moment so wanted to mark a working version.

* - Pool classes will reuse the same "pool_logging_name" settingMike Bayer2010-05-301-1/+2
| | | | | | | | | | | | | | | | | | | | after a dispose() occurs. - Engine gains an "execution_options" argument and update_execution_options() method, which will apply to all connections generated by this engine. - Added more aggressive caching to the mapper's usage of UPDATE, INSERT, and DELETE expressions. Assuming the statement has no per-object SQL expressions attached, the expression objects are cached by the mapper after the first create, and their compiled form is stored persistently in a cache dictionary for the duration of the related Engine. - change #3 required change #1 so that we could test a set of mappers operating over the course of many engines without memory usage increase.
* - threadlocal engine wasn't properly closing the connectionMike Bayer2010-02-271-0/+2
| | | | | | | | | | upon close() - fixed that. - Transaction object doesn't rollback or commit if it isn't "active", allows more accurate nesting of begin/rollback/commit. - Added basic support for mxODBC [ticket:1710]. - Python unicode objects as binds result in the Unicode type, not string, thus eliminating a certain class of unicode errors on drivers that don't support unicode binds.

WVD had a lot of overhead, apparently. *CAUTION* - im pretty confident about this change, as the threadlocal dict gets explicitly managed anyway, tests pass with PG etc., but keep a close eye on this one regardless.
