hi,
my first post here ;)
PSGI (looks similar to the eyetoy example, but does not work for me):
...
uwsgi::websocket_handshake($env->{HTTP_SEC_WEBSOCKET_KEY},
$env->{HTTP_ORIGIN});
while(1) {
# wait for updates in the sharedarea
uwsgi::sharedarea_wait(0, 50); # this is line 70
# send a binary websocket message directly from the sharedarea
uwsgi::websocket_send_from_sharedarea(0, 0);
}
INI
[uwsgi]
plugins = http,0:psgi,coroae
psgi = /path/to/my.psgi
http-socket = :8080
master = true
coroae = 40
http-websockets = true
sharedarea = 1
uid = www-data
gid = www-data
testing uwsgi 2.0.3 and 2.0.4, both fail with:
[uwsgi-perl error] FATAL: Coro SLF calls can only be made normally, not
via goto or any other means, caught at ... line 70.
-> multiple times

Need to check it, but in the mean time can you try with latest
coro::anyevent package ? (from sources)
coro::anyevent 6.37 (04.03.2014) is the latest available package showed
by cpan...
no clue where to find nightly builds or something similar...
Unfortunately that error pop-up when libev engine is loaded in coro
(Coro::EV). I did not understand why it is triggered but i was able to
fake it calling Coro::AnyEvent::sleep using perl_eval_pv:
https://github.com/unbit/uwsgi/blob/master/plugins/coroae/coroae.c#L68
definitely not a great way, but it should work
Let me know
yes, that solved the problem.
but i ask myself if using sharedarea_wait() with
websocket_send_from_sharedarea()
is the only way for broadcasting data to all listeners.
your eyetoy example looks ideal to this method.
but a simple chat (single user sends message to all listeners) seems
much more difficult to me than i expected.
i'll keep trying...
kind regards
alex
