New Features and improvements

Allow calling the spooler from every CPython context

At Europython 2014, Ultrabug (an uWSGI contributor and packager) asked for the possibility to spool tasks directly from a greenlet.

Done.

store_delete cache2 option

Author: goir

The store_delete flag of the --cache2 option allows you to force the cache engine to automatically remove invalid backing store files instead of steadfastly refusing to launch.

file logger rotation

Author: Riccardo Magliocchetti

The file logger has been extended to allow the use of rotation (the same system used by the non-pluggable --logto).

Vassal plugin hooks

The plugin hook API has been extended with two new hooks: vassal and vassal_before_exec.

They allow customizing a vassal soon after its process has been created.

The first third-party plugin using it is 'apparmor': https://github.com/unbit/uwsgi-apparmor

This allows you to apply an Apparmor profile to a vassal.

Broodlord improvements

The Broodlord subsystem has been improved with a new option: --vassal-sos that automatically ask for reinforcement when all of the workers of an instance are busy.

In addition to this a sysadmin can now manually ask for reinforcement sending the 'B' command to the master FIFO of an instance.
