Address already in use about actix-web HOT 13 CLOSED

Yes, it is a problem at the moment. I have “gracefull shutdown” item in my todo list

from actix-web.

Btw thanks for reporting this problems, it is very helpful

from actix-web.

After your last commit, i search now how catch SIGINT, SIGTERM ... i have found Signal handling – Tokio Example but i don'k know how use it whith actix. What solution did you code to catch the signals ?

Thanks.

You try this actor https://github.com/actix/actix/blob/master/src/actors/signal.rs

from actix-web.

I checked example, it should just work. All you need to do is send StopServer to http server on sigterm.

I will add example

from actix-web.

i wait your example because i don't understand what to do.

I have clone actix, set my Cargo.toml with actix = { "path" = "../actix", features=["signal"] }
and what to do after ...

how change let addr = HttpServer::new(...).bind(...).spaw() to include let addr: SyncAddress<_> = Signals.start(); and after (when SIGTERM) call StopServer ?

I you have a full example, i take.
Thanks for your help.

I added signals support, but I think api could be better

here is example https://github.com/actix/actix-web/tree/master/examples/signals

from actix-web.

Sorry, but I still don't understand how to call the StopServer api after the sigterm signal inside a function which call dev::StopSever + print a graceufll message (by example) + and unconnect db (by example). Is not clear.

from actix-web.

it is not possible to call any arbitrary function on signal at the moment.
if you want to receive signals, you need to implement as Handler for Signal message.

but I see your problem, I will think about this problem.

from actix-web.

btw usually you don't need explicit disconnect in rust, usually connections get closed on "drop"

from actix-web.

I understand better https://actix.github.io/actix-web/guide/qs_3_5.html

I have set .shutdown_timeout(1) (DEV mode) and i feel like I don't have any more latency time when the application is restarted with cargo watch -x run.

from actix-web.

only SIGTERM is graceful restart, SIGINT and SIGQUIT are force restart
