| Summary | 0004978: Engine hangs in SDL2 / libX11 after load (linux/nvidia driver) | ||||||||
| Description | I built this engine from 100.0 tag in git. The version string was manually set to 100.0 in order to join public servers. I was able to join a game once after building. After a reboot, subsequent attempts to load a game result in a hang. The watchdog thread gives the following, after a brief delay at load: [f=0000000] [LuaIntro] LuaIntro v1.0 (Lua 5.1) [... ~5 sec delay ...] [f=0000000] Warning: [Watchdog] Hang detection triggered for Spring 100.0.

| Additional Information | The main thread is hanging inside SDL2/libX11. Obviously I do not have the source or debuginfo for these compiled in but it seems to be inside XSync / XReply: looks like SDL2 events. Are there SDL2 parameters that I can tweak to attempt a workaround or to diagnose? | ||||||||

Update: The hang occurs for both Balanced Annihilation and Tech Annihilation in network play. Update: I can start the engine from the command line ("./spring") and it will arrive at the system menu with no hang. I can also start a 1-player in the "testing only" sandbox and it will load and function correctly. |

(22:18:00) [99]Gambit: it's 100.0-33-gfa5d693 -- it is based on 100.0 with a few changes (22:18:15) abma_irc: then you broke the code |

No, it still happens with 100.0 and with the tarball. I checked 100.0 before posting, obviously. The changes I made are nothing that would break anything. |

possible related to 0004952 the nvidia driver seems to cause a bug there |

This problem went away with Safemode = 1 in springlobby.conf. Unfortunately, this does not look like the true fix. When I revert back to Safemode = 0, the problem vanishes and the engine starts properly again. So the problem may involve some hysteresis or memory on the part of the driver (if it is in fact the nvidia driver). Also, the next line after the hang *should* read one of the two: [f=0000000] LoadingScreen: single-threaded or [f=0000000] Registering thread controls for thread [load] ...depending on whether you have LoadingMT=-1 or LoadingMT=0 |

reminiscent of 0004908 (although without the error messages), but too old now and not reported by anyone else. |
