In FluidSynth 2.2.0 an extra state was added to denote stopping. To transition
from this state to a stopped state the rendering needs to be running. Since
04ce1f07 locking was added that skipped the rendering when something else held
a lock, so the state would never get to stopped and join would never return.
Under normal circumstances the server's ID is 32 characters excluding '\0', however this can be changed at the server. This ID is sent to the server for company name hashing. The client reads it into a statically allocated buffer of 33 bytes, but fills only the bytes it received from the server. However, the hash assumes all 33 bytes are set, thus potentially reading uninitialized data, or a part of the server ID of a previous game in the hashing routine.
It is still reading from memory assigned to the server ID, so nothing bad happens, except that company passwords might not work correctly.
If a viewport sign straddles the top of a viewport, a crash will occur if the viewport height is zero. This is resolved by simply not attempting to draw the viewport in this situation, consistent with other widgets.
One could join a network game from within an already running network game. This would call a NetworkDisconnect, but keeps the UI alive. If, during that process the join is aborted, e.g. by cancelling on a password dialog, you would still be in your network game but also get shown the server list.
Solve all the underlying problems by falling back to the main UI when (re)connecting to a(nother) server.
The idea is that if you query an older server that does not support
this packet yet, the client receives an error. The assumption was
that on every "illegal packet" the connection would be closed. This
turns out to be false.
Now CLIENT_GAME_INFO aligns with the old PACKET_CLIENT_NEWGRFS_CHECKED,
which does a pre-check (which fails), and an error is sent back
and the connection is closed.
This is not a nice solution, but it is the best we got.
They are likely not working as expected on Windows, so prevent their usage.
Winsock does not set errno and strerror does not return anything useful for Winsock error numbers.
YAPF was constantly measuring its performance, but only at
certain debug-levels this information was shown.
Now after years, I sincerely wonder if anyone still knows about this
feature and who still use it. Especially with the new framerate window,
this detailed performance is not as meaningful anymore as it once
was.
