New Features and Backports
--------------------------

The custom worker api
*********************

Finally you are able to override the uWSGI processing model to completely get control of it. This is very similar to what
you can do in projects like gunicorn (and its integration with tornado or gevent). Obviously native plugins are still the best approach (they allow integration with uWSGI api and states), but in some case you may want to use uWSGI process management facilities and let your app do the rest of the work.

Currently only the python plugin supports "overriding" of workers, an aiohttp (asyncio) example module is available:

https://github.com/unbit/uwsgi-docs/blob/master/WorkerOverride.rst


--wsgi-disable-file-wrapper
***************************

This option disables the wsgi.file_wrapper optimization of the WSGI standard. In some corner case this is the only trick to avoid errors.

Official PHP 7 support
**********************

PHP 7 is now officially supported in the php plugin.


uwsgi.spooler_get_task api (Credits: Alexandre Bonnetain)
*********************************************************

This patch allows you to easily parse spooler files.

Check the example/test here:

https://github.com/unbit/uwsgi/blob/master/t/spooler/read.py

--if-hostname-match (Credits: Alexandre Bonnetain)
**************************************************

This options for config logic allows you to define options only when a regexp over the hostname matches:

.. code-block:: ini

[uwsgi]
if-hostname-match = ^prod
threads = 20
endif =

New Features
************

The unix_signal hook
^^^^^^^^^^^^^^^^^^^^

You can now remap UNIX signals to specific functions symbols:

.. code-block:: c

#include <stdio.h>

void hello_world(int signum) {
printf("Hello World\n");
}

.. code-block:: sh

gcc -o libhello.so -shared hello.c
uwsgi --dlopen ./libhello.so --hook-master-start "unix_signal:1 hello_world" ...

will run the function hello_world whenever signal 1 (SIGHUP) is raised

New Features
************

The mem_collector thread
^^^^^^^^^^^^^^^^^^^^^^^^

Evil memory monitors (like --evil-reload-on-rss) are now asynchronously managed by a dedicated thread.

This solves the issue of runaway processes not catched by the master.

fixpathinfo routing action
^^^^^^^^^^^^^^^^^^^^^^^^^^

This is another step in removing the need of the infamous uwsgi_modifier1 30 relic.

This routing action assumes the PATH_INFO cgi var has the SCRIPT_NAME part included.

This action allows you to set SCRIPT_NAME in nginx without bothering to rewrite the PATH_INFO (something nginx cannot afford)

.. code-block:: ini

[uwsgi]
; blindly assumes PATH_INFO is clobbered with SCRIPT_NAME
route-run = fixpathinfo:

uwsgi[sor] and time[micros] routing vars
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

This two new vars exposes the start of the current request (in micros) and the current time (again in micros)

.. code-block:: ini

[uwsgi]
route-run = log:request started at ${uwsgi[sor]}
route-run = log:current micros time is ${time[micros]}

wait-for-socket
^^^^^^^^^^^^^^^

This works like wait-for-fs/iface/file/dir

The spawn of the instance is suspended until the specified tcp/unix socket is ready.

You can use it to synchronize vassals spawn (like stopping a vassal until a postgresql server has been spawned)

wait_for hooks
^^^^^^^^^^^^^^

All of the wait-for-* functions can now be used as a hook:

.. code-block:: ini

[uwsgi]
; wait for postgres soon after privileges drop
hook-as-user = wait_for_socket:127.0.0.1:5432
