SQLAlchemy is the Python SQL toolkit and Object Relational Mapper that gives application developers the full power and flexibility of SQL. SQLAlchemy provides a full suite of well known enterprise-level persistence patterns, designed for efficient and high-performing database access, adapted into a simple and Pythonic domain language.
v1.0 [Jul 16, 2015]
[engine] [bug] Fixed critical issue whereby the pool “checkout” event handler may be called against a stale connection without the “connect” event handler having been called, in the case where the pool attempted to reconnect after being invalidated and failed; the stale connection would remain present and would be used on a subsequent attempt. This issue has a greater impact in the 1.0 series subsequent to 1.0.2, as it also delivers a blanked-out .info dictionary to the event handler; prior to 1.0.2 the .info dictionary is still the previous one.¶
[sqlite] [bug] Fixed bug in SQLite dialect where reflection of UNIQUE constraints that included non-alphabetic characters in the names, like dots or spaces, would not be reflected with their name.¶
[misc] [bug] Fixed an issue where a particular base class within utils didn’t implement __slots__, and therefore meant all subclasses of that class didn’t either, negating the rationale for __slots__ to be in use. Didn’t cause any issue except on IronPython which apparently does not implement __slots__ behavior compatibly with cPython.¶
Feature-rich relational database known for its high performance and excellent concurrency
