uWSGI 2.0.6

Changelog [20140701]

    fixed a memory leak with subscription system
    fixed shortcut for ssl-socket
    fixed apache2 mod_proxy_uwsgi (it is now considered stable with all mpm engines)
    fixed SCRIPT_NAME and PATH_TRANSLATED generation in php plugin
    remove the old FIFO socket from the event queue when recreating it

New features
The new Rados plugins

The rados plugin has been improved and stabilized, and now it is considered \ 
usable in production.

Async modes and multithreading correctly works, and support for uploading \ 
objects (via PUT) and creating new pools (MKCOL) has been added.

Expect webdav support in uWSGI 2.1

Docs have been updated: http://uwsgi-docs.readthedocs.org/en/latest/Rados.html

This is a configuration logic for including options only when the specified \ 
hostname matches:

if-hostname = node1.local
  socket = /tmp/socket1.socket
endif =

if-hostname = node2.local
  socket = /var/run/foo.socket
endif =

Apache2 mod_proxy_uwsgi stabilization

After literally years of bug reports, and corrupted data, the mod_proxy_uwsgi is \ 
now stable, and on modern apache2 releases it supports unix sockets too.

Updated docs: http://uwsgi-docs.readthedocs.org/en/la … roxy-uwsgi
uwsgi[rsize] routing var

this routing var (meaningful only in the 'final' chain) exposes the response \ 
size of the request
the callint scheme

This scheme allows you to generate blob from functions exposed by your uWSGI \ 

uid = @(callint://get_my_uid)
gid = @(callint://get_my_gid)


The corerouters fallback procedure requires a valid key (domain name) has been \ 
requested. This option forces the various routers to trigger the fallback \ 
procedure even if a key has not been found.
php 5.5 opcode caching via -php-sapi-name

For mysterious reasons the opcode caching of php5.5 is not enabled in the embed \ 
sapi. This option (set it to 'apache' if you want) allows you to fake the opcode \ 
caching engine forcing it to enable itself.
Improved chain-reloading

Thanks to Marko Tiikkaja the chain reloading procedure correctly works in \ 
cheaper modes and it is more verbose.
added 'chdir' keyval to -attach-daemon2

You can now set where attached daemons need to chdir()

    fixed mule_get_msg EAGAIN

New features
graceful reload of mule processes

SIGHUP is now sent to mules instead of directly killing them. You are free to \ 
trap/catch the signal in the 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

The new action will allow users to write simplified "break" clause.

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 goes wrong.

this new option, completely disables the blacklisting Emperor 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 \ 

For example the --http-manage-source option allows the HTTP router to honour \ 
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 of them \ 
could be really slow.

Three new options have been added allowing you to disable the generation of \ 
core-related metrics and (eventually) their usage in the stats server.
sharedarea improvements

The sharedarea api continues to improve. Latest patches include support for \ 
mmapping device directly from the command line.

A funny way for testing it, is mapping the raspberrypi BCM2835 memory, the \ 
following example allows you to read the rpi system timer

uwsgi --sharedarea file=/dev/mem,offset=0x20003000,size=4096 ...

now you can read the 64bit value from the first (zero-based) sharedarea:

# read 64bit from 0x20003004
timer = uwsgi.sharedarea_read64(0, 0x04)

obviously, pay attention when accessing rpi memory, an error could crash the \ 
whole system !!!

This exit code (15) can be raised by a worker to tell the master to not respawn it
PROXY1 support for the http router

The option --http-enable-proxy-protocol allows the HTTP router to understand \ 
PROXY1 protocol requests (like the ones made by haproxy or amazon elb)
reset_after_push for metrics

This metric attribute ensure that the matric value is reset to 0 (or its \ 
hardcoded initial_value) evry time the metric is pushed to some external system \ 
(like carbon, or statsd)

This routing action allows you to completely override the REMOTE_ADDR detected \ 
by protocol handlers:

; treat all requests as local
route-run = setremoteaddr:

the resolve option

There are uWSGI options (or plugins) that do not automatically resolves dns name \ 
to ip addresses. This option allows you to map a placeholder to the dns \ 
resolution of a string:

; place the dns resolution of 'example.com' in the 'myserver' placeholder
resolve = myserver=example.com
subscribe2 = server=%(myserver),key=foobar

New features and improvements
CGI plugin

The plugin has been improved to support streaming.

In addition to this the long-awaited async support is finally ready. Now you can
have CGI concurrency without spawning a gazillion of expensive threads/processes

Check: Running CGI scripts on uWSGI
PSGI loading improvements

The PSGI loader now tries to use Plack::Util::load_psgi() function instead of
simple eval. This addresses various inconsistences in the environment (like the
double parsing/compilation/execution of psgi scripts).

If the Plack module is not available, a simple do-based code is used (very
similar to load_psgi)

uWSGI 2.0

Changelog [20131230] Important changes

Dynamic options have been definitely removed as well as the
broken_plugins directory Bugfixes and improvements

    improved log rotation do not rely on unix signals to print
    request status during harakiri added magic vars for uid and
    gid various Lua fixes a tons of coverity-governed bugfixes made
    by Riccardo Magliocchetti

New features --attach-daemon2

this is a keyval based option for configuring external daemons.

Updated docs are: :doc:`AttachingDaemons` Linux setns() support

One of the biggest improvements in uWSGI 1.9-2.0 has been the total
support for Linux namespaces.

This last patch adds support for the setns() syscall.

This syscall allows a process to "attach" to a running namespace.

uWSGI instances can exposes their namespaces file descriptors
(basically they are the files in /proc/self/ns) via a unix socket.

External instances connects to that unix socket and automatically
enters the mapped namespace.

to spawn an instance in "namespace server mode", you use the
--setns-socket <addr> option

uwsgi --setns-socket /var/run/ns.socket --unshare net,ipc,uts ...

to attach you simply use --setns <addr>

uwsgi --setns /var/run/ns.socket ...

Updated docs: :doc:`Namespaces` "private" hooks

When uWSGI runs your hooks, it verbosely print the whole hook action
line. This could be a security problem in some scenario (for example
when you run initial phases as root user but allows unprivileged
access to logs).

Prefixing your action with a '!' will suppress full logging:

[uwsgi] hook-asap = !exec:my_secret_command

Support for yajl library (JSON parser)

Til now uWSGI only supported jansson as the json parser required
for managing .js config files.

You can now use the yajl library (available in centos) as alternative
JSON parser (will be automatically detected) Perl spooler support

The perl/PSGI plugin can now be used as a spooler server:

uwsgi::spooler(sub {
     my $args = shift; print Dumper($args); return -2; });

The client part is still missing as we need to fix some internal
api problem.

Expect it in 2.0.1 ;) Gateways can drop privileges

Gateways (like http router, sslrouter, rawrouter, forkptyrouter
...) can now drop privileges independently by the master.

Currently only the http/https/spdy router exposes the new option
(--http-uid/--http-gid) Subscriptions-governed SNI contexts

The subscription subsystem now supports 3 additional keys (you can
set them with the --subscribe2 option):




all of the takes a path to the relevant ssl files.
