touch-reload style for clearing the cache

[unbit]

In a project (my company website) i have added

touch-reload = .git/index

to trigger an instance reload whenever the git repository changes. This is mainly to clear the uWSGI cache as each page (after generated) is put there and served using the 'cache internal router'

Reloading the whole server (only to clear the cache) seems overkill, so a

--touch-cache-clear

would be a great (and cheap) solution

[akx]

Wouldn't just filemon signals + cache_clear() do?

EDIT: So as to keep the core a little bit leaner, or to have a more "hackable" solution.

i think the way of "touch" files has been abused (see logrotate and logreopen). The master fifo way is a lot better for sure. We can eventually add a command to clear the cache.

I'm looking for a command to clear the cache on certain URI for instance.

Is touch-reload = .git/index the only solution ?

[unbit]

you could map a file monitor to a uwsgi.cache_clear() api command:

uwsgi.register_file_monitor(0, "/tmp", "worker", do_clear_cache)

def do_clear_cache(signal_number, filename):
    uwsgi.cache_clear()

Thanks @unbit, is there anything that could be used with the internal routing such as http://uwsgi-docs.readthedocs.io/en/latest/InternalRouting.html#the-first-example
