New features
The experimental asyncio loop engine (CPython >= 3.4)
asyncio (also known as 'tulip') is the new infrastructure for writing non-blocking/async/callback-based code with Python 3.
This plugin (experimental) allows you to use asyncio as the uWSGI loop engine
Docs: http://uwsgi-docs.readthedocs.org/en/latest/asyncio.html
httprouter advanced timeout management
The http router got 2 new specific timeout:
-http-headers-timeout <n> ; defines the timeout while waiting for http headers
-http-connect-timeout <n> ; defines the timeout when connecting to backend instances
they should help the sysadmin in improving security and availability
allow disabling cache warnings in -cache2
the 'ignore_full' keyval option has beed added to cache2. This will disable warnings when a cache is full
purge LRU cache feature by Yu Zhao (getcwd)
This new mode allows you to configure a cache to automatically expires least recently used (LRU) items when it is full.
Just add purge_lru=1 to your cache2 directive
support embedded config on FreeBSD
You can now embed config on FreeBSD systems:
http://uwsgi-docs.readthedocs.org/en/latest/Embed.html#step-2-embedding-the-config-file
rpc hook
Two new hooks have been added:
'rpc' -> call the specified rpc function (fails on error)
'rpcretry' -> call the specified rpc function (retry on error)
setmodifier1 and setmodifier2 routing actions
having to load the 'uwsgi' routing plugin just for setting modifiers was really annoying. This two routing actions (embedded in the core) allows you to dinamically set modifiers.
no_headers option for static router
keyval based static routing action can now avoid to rewrite response headers (useful for X-Sendfile), just add no_headers=1 to your keyval options.
uWSGI 2.0.3
Bugfixes
fixed spooler 'at' key usage
fixed a memory and fd leak with on-demand Emperor sokets
on __APPLE__ use LOG_NOTICE for syslog plugin
fixed mongrel2 support
hack for avoiding libmongoclient to crash on broken cursor
log alarm is now a uwsgi_log_verbose() wrapper
fixed tuntap router memory corruption
Set ECDHE curve independently from DHE parameters (Hynek Schlawack)
do not wait for a whole Emperor cycle before checking for each waitpid
fix a regression with caller() not indicating the starting *.psgi program (Ævar Arnfjörð Bjarmason)
New features
Emperor SIGWINCH and SIGURG
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
or
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 {
uwsgi::add_var("newvar","newvalue");
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)
