Web front-end

fcgi and flup

Trac uses its own private copy of an old version of ​flup, which works well for basic needs.

More demanding setups may want to use a more recent flup version, notably to benefit from its ​thread pool.

Now Trac detects and uses the installed version of flup, and only falls back to its own version if flup is not installed.

See #9111 for details

Caveats

• This release requires a database upgrade when upgrading from the 0.12.x series:

  trac-admin $TRAC_ENV upgrade
  

• PySqlite 1.1.x is no longer supported; use PySqlite 2 (requires version ≥ 2.5.5 or < 2.5.2, see #9434 for details)

Developer-visible changes

A detailed view of the API changes since 0.12.x can be found in TracDev/ApiChanges/1.0.
