                                                        BuildbotEngineStrategy

A subclass of the ThreadLocalEngineStrategy that can effectively interact with Buildbot.

This adjusts the passed-in parameters to ensure that we get the behaviors Buildbot wants from particular drivers, and wraps the outgoing Engine object so that its methods run in threads and return deferreds.

Nested Classes
Inherited from `sqlalchemy.engine.strategies.ThreadLocalEngineStrategy`: `engine_cls`

Instance Methods

special_case_sqlite(self, u, kwargs)
For sqlite, percent-substitute %(basedir)s and use a full path to the basedir.

source code

special_case_mysql(self, u, kwargs)
For mysql, take max_idle out of the query arguments, and use its value for pool_recycle.

source code

create(self, name_or_url, **kwargs)
Given arguments, returns a new Engine instance.

Method Details

special_case_sqlite(self, u, kwargs)

source code

For sqlite, percent-substitute %(basedir)s and use a full path to the basedir. If using a memory database, force the pool size to be 1.

special_case_mysql(self, u, kwargs)

source code

For mysql, take max_idle out of the query arguments, and use its value for pool_recycle. Also, force use_unicode and charset to be True and 'utf8', failing if they were set to anything else.

create(self, name_or_url, **kwargs)

source code

Given arguments, returns a new Engine instance.
