Client-Server synchronization on Client's shutdown

[modern-nm]

Hi, I am trying to make some feature and i have a problem that I cant solve for a long time. I cant make client to send a custom NetMessage to server for some post processing AFTER user hit "Close" button of ss14 window. I trying to send NetMessage on public override void Shutdown() of Content.Client\Entry\EntryPoint.cs. It is the most early point after "[INFO] game: Shutting down! Reason: Main window closed" i found to inject my code. So I call method _netManager.ClientSendMessage(msg); on Client side.
After that i expect that server capture my message OnSyncMessage(MyNetMessage msg) and process it, but i got [WARN] net: [::1]:59298: Received data message, but not connected. only (if server started in debug mode/ otherwise i dont recieve even that).
But.. if I place such bloody shit like System.Threading.Thread.Sleep(100); right after _netManager.ClientSendMessage(msg); magic is happened and my message delivered and processed. As i think, message is not delivered because client net status is Disconnected already. I cant find way to make netManager send it and dont die while message is flying to server

Help me, im under water

Uhm, why are you trying to do this?

I trying to make a chat autocompletion feature to make input faster. I gather chat messages on client and i want to sync autocompletion dictionary with server to give dictionary back to client on next connect of user.

just store it on the client to begin with instead of juggling it around

That is a very bad way to do that. If the client crashes or gets disconnected due to a network error, you are out of luck. Not to mention that "closes the window" is not the only way the client can get cleanly disconnected from the server.

You should be storing that data locally in writable storage, or continuously synchronizing it to the server.

I already tried it, I stored it in JSON but it made me to edit sandbox.yml in RobustToolbox... unacceptable. I dont know how to store it on the client properly, so i dropped it and proceed to client-server sync. I thought I'll make it continuously synchronizing it to the server and sync on player disconnecting. But for debug I started with sync on disconnecting. Will it be enough to send deltas every N seconds or ticks? What do u think?

Just use Robust's built in YAML serializer. You can look at character profile import/export as example.

I'll try it
