PySqlite

​PySqlite is a Python binding for the ​SQLite light-weight database engine, which is Trac's default DatabaseBackend.

It should still be possible to use the old SQLite 2.8.x with the Pysqlite ​1.0.1, but Trac 0.9 works best with SQLite 3.2.x. The compatible Python bindings are:

• either the 1.x release branch of PySqlite (version 1.1.6 as of this writing)
• or, better, the newer 2.0.x release branch (version ≥ 2.0.5 preferred)
• (the upcoming 2.1.x release branch has just been started and has not yet been tested with Trac)

Recent versions are available from ​there.

Note: If you want to use Trac in a multi-threaded setup by using either TracModPython or TracStandalone, be sure to build a thread-safe version of SQLite, by using the --enable-threadsafe configuration switch. If you use a non thread-safe library, which is unfortunately what you get by default on non-windows platforms, you face the risk to get persistent database locks (see #2170).
