graceful reload of mule processes (Credits: Paul Egan)¶
SIGHUP is now sent to mules instead of directly killing them. You are free to trap/catch the signal in your code. If a mule does not die in the allowed “mercy time” (–mule-reload-mercy, default 60 seconds), SIGKILL will be sent.
return routing action (Credits: Yu Zhao)¶
This new action will allow users to write simplified “break” clauses.
For example, “return:403” is equivalent to “break:403 Forbidden”, with response body “Forbidden”.
The response body is quite useful for telling end users what’s going wrong.
This new option completely disables the Emperor’s blacklisting subsystem.
Icecast2 protocol helpers¶
One of the upcoming unbit.com projects is a uWSGI based audio/video streaming server.
The plugin (should be released during Europython 2014) already supports the Icecast2 protocol.
A bunch of patches have been added to the HTTP router to support the Icecast2 protocol.
For example the
--http-manage-source option allows the HTTP router to honor SOURCE method requests, automatically placing them in raw mode.
–metrics-no-cores, –stats-no-cores, –stats-no-metrics¶
When you have hundreds (or thousands) of async cores, exposing metrics for them may get really slow.
Three new options have been added allowing you to disable the generation of core-related metrics and consequently their usage in the stats server.
This exit code (15) can be raised by a worker to tell the master to not respawn it.
PROXY1 support for the http router (Credits: bgglenn)¶
--http-enable-proxy-protocol allows the HTTP router to understand PROXY1 protocol requests, such as those made by Haproxy or Amazon Elastic Load Balancer (ELB).
reset_after_push for metrics (Credits: Babacar Tall)¶
This metric attribute ensures that the metric value is reset to 0 (or its hardcoded initial_value) after the metric is pushed to external systems (such as Carbon or StatsD).
This new routing action allows you to completely override the REMOTE_ADDR detected by protocol handlers:
[uwsgi] ; treat all requests as local route-run = setremoteaddr:127.0.0.1
the resolve option¶
There are uWSGI options (or plugins) that do not automatically resolve DNS names to IP addresses. This option allows you to map a placeholder to the DNS resolution result of a string:
[uwsgi] ; place the dns resolution of 'example.com' in the 'myserver' placeholder resolve = myserver=example.com ; %(myserver) would now be 220.127.116.11 subscribe2 = server=%(myserver),key=foobar
uWSGI 2.0.5 has been released on  and can be downloaded from:
