Management Flags

You can remotely (and without taking offline the uWSGI server) modify the behaviour of the uWSGI stack.

Using the uwsgi protocol you can enable/disable/setup the internal options.

All the flags take an unsigned 32bit value (so the block size is always 4) that contain the value to set for the flag. If you do not specify this value (so you send only the uwsgi header) the server will count it as 0.

This is a table of flag available:

flag	action	note
0	logging	enable/disable logging
1	max_requests	set maximum number of requests per worker
2	socket_timeout	modify the internal socket timeout
3	memory_debug	enable/disable memory debug/report
4	master_interval	set the master process check interval
5	harakiri	set/unset the harakiri timeout
6	cgi_mode	enable/disable cgi mode
7	threads	enable/disable python threads
8	reaper	enable/disable process reaper

A simple (and ugly) script is included to remotly change management flags:

./uwsgi --no-server -w myadmin --pyargv "192.168.173.16 3031 0 0"

the command will disable logging on the uWSGI server listening on 192.168.173.16 port 3031

and

./uwsgi --no-server -w myadmin --pyargv "192.168.173.16 3031 0 1"

will re-enable it
