New features


The Emperor now responds to two new signals:

SIGWINCH: force an emperor rescan of vassals

SIGURG: cleanup the Emperor states (for now it only clears its blacklist)

Building plugins on-the-fly from git repositories

You can now build plugins stored on git servers:

uwsgi --build-plugin https://github.com/unbit/uwsgi-bonjour


UWSGI_EMBED_PLUGINS="bonjour=https://github.com/unbit/uwsgi-bonjour" pip install uwsgi

uwsgi.add_var(key, value)

You can now set request variables direcly from your app, for better integration with the internal routing subsystem

my $app = sub {
     return [200, ['Content-Type' => 'text/html'], ["Hello"]];
uwsgi --http-socket :9090 --psgi hello.pl --response-route-run "log:\${newvar}"

add_var has been implemented in the CPython and Perl plugins

‘disableheaders’ routing action

This new action disables the sending of response headers, independently by the current request state

Smarter Emperor on bad conditions

Now the Emperor completely destroys internal vassal-related structures when it is impossible to correctly kill a broken vassal (both for inconsistent Emperor state or for internal system problems)
