Stall at JDA build when Dynmap is on the same server
LemADEC opened this issue · 19 comments
As of DiscordSRV-Build-1.16.9, plugin may lock the server at boot, just before reporting the Discord server channel.
Here's an observed failed boot

May I ask what the actual reason is behind using a blocking method (JDABuilder#build().awaitReady()) over just using things like a ReadyListener to declare DiscordSRV as "ready"?
Because there are certain parts of DiscordSRV that require DiscordSRV to be ready, and blocking it is ok because it is on it's own thread. What could have been happening here is a deadlock (some how)
Issue has gone stale, and there have been many updates that might effect this. Will be reopened if the issue can still be reproduced by someone
This has nothing to do with DiscordSRV.
This is an error from Dynmap.

No, it's not an error from Dynmap, look again the next successful boot.
Dynmap is running in a separate thread anyway.
I know what my plugin looks like when it starts, thanks.
I’m not going to look into this unless you can produce another log that has only DiscordSRV’s output and you’ve given DiscordSRV sufficient time to connect.
As seen in the second log, the "Error loading configuration file for Steamcraft" log is a 'normal' error during a successful boot, as such it's not representative of the issue in failed boot.
As seen in the first log, the server was down for almost 2h, seems fairly sufficient time to connect.
From a quick check in DiscordSRV, we can see a blocking wait in the JDA Builder:
As per JDA documentation, the API has timeout that defaults to 0, which means infinite wait. Early in version 3.0.x, they added ways to define actual timeout values. Latest version seems to provide this through setWebsocketFactory(), setHttpClientBuilder() and setHttpClient().
However, since both Dynmap and DiscordSRV are unresponsive when issue happens, both being in different threads, we would need to consider other possibilities of bad multi-threading, notably in log4j (seems unlikely), SSLContext.setDefault() (weird, but still possible). By extension, it seems unlikely that we can reproduce the issue with just DiscordSRV here.
Long story short, adding finer logs during DiscordSRV initialization may help narrow down where the collision is happening, possibly use this opportunity to add actual timeouts to JDA would make a nice improvement.
People use DiscordSRV with Dynmap all the time... This is likely an issue with an old/newer version of Dynmap that the general public isn't using
Maybe try putting DiscordSRV/Dynmap to load before each other?
Any other plugins that might have similar dependencies? Like something with a web server or maybe even votifier?
Today a different server got stuck with similar symptoms. Interestingly, that server doesn't have Dynmap.

craftbukkit 1.8.8
dynmap 2.1-alpha-1
votifier 1.9
Could you try testing on a non-forge server (spigot/craftbukkit) 1.7.10 with the same plugins and see if the issue persists?
If that still doesn't work, please provide a full list of your plugins
Issue is very intermittent in nature, we can't reproduce on command, we can only wait for the next occurrence. As such, adding more logs during boot may help understand the problem next time we catch it.
The full list of plugins from the second server is right above your post @Vankka . There's no Dynmap mod on that server, just the DynmapCBBridge which I forgot to remove.

The Dynmap version reported is from the CBBridge, the actual Dynmap mod is 2.6-beta-1-forge-1.7.10.
How often does it happen? or is it just random?
The output with DebugJDA set to true (during startup) would probably the most helpful atm (needs to be on latest dev build)
it's about once a month, with 3 servers rebooting every 4 hours.
Is there an environment variable to enable DebugJDA or do I need a new compilation of the plugin?
Config option, some stuff was changed related to it in dev builds,
Latest dev build download link: https://ci.scarsz.me/guestAuth/app/rest/builds/id:102/artifacts/content/DiscordSRV-Build-1.17.0-SNAPSHOT-120.jar
(though since it's so hard to reproduce, and debug logs a ton of log messages, you probably should not have it on all the time)
I didn't see much added logs during boot with just DebugJDA: true.
Should I just set DebugJDA: true, or also set DebugLevel: 1?
I'm on the build you've linked.
DebugJDA has no visible effect during boot.
DebugLevel: 2 adds some callstacks:
