#639 thread safety of playerc_client_writepacket

Player (393)
Jayen Ashar

We've got a player client with two threads: one for sending commands, and one for receiving data. The two threads use the same playerc_client_t and are in PULL mode. In pull mode, the player client sends a packet, so in our multi-threaded client, it occasionally collides with sending a command, causing the player server to receive an invalid packet and crash. I've attached a patch to fix this.

    In our multi-threaded client, we don't seem to be hitting the system's 8MB stack limit, but I am hitting it in clients like playerv. So, while this patch makes the write_xdrdata a local variable and makes playerc_client_writepacket thread-safe, it exceeds common stack limits, requesting 32MB on the stack.

    I'll update this tracker item soon with a new patch, which will work for playerv without changing the stack limit.
