segfault in FRM_Trains::getTrains

[nward]

Great mod, but unfortunately it's been crashing for us every couple of hours.

Unsure if you're open to these - but here's a stack trace from a crash in FRM_Trains::getTrains:

[porisius]

Thanks, I'll look when I get a moment

[porisius]

Troubleshooting this, any chance that you have a train that, isn't at a station and doesn't have a schedule configured?

I'm not saying it is your problem, but why the problem is happening.

[nward]

Yes I do - I have one that's permanently like that (disconnected from the main train network and just used to test layouts) and we also use trains manually driven from time to time.

Actually, I think that one time we had the crash, I was driving a manual train and I'd just crashed it heh.

[porisius]

Thanks, I think a null value is the problem. I will give that a try

[porisius]

This seems to fix it for me. I just have a locomotive that I just built and called the API.

Uploading FRM 1.0.10 now

[cavejonhon]

I just ran into this problem on version 1.0.10. It seems like getting in a freshly spawned train crashes the server immediately. The crash report seems pretty identical to the one posted here as well.

[porisius]

Looks like it gets a MultiUnitMaster, but without a train TimeTable schedule it is null and says "nope".

[porisius]

I have a test build uploaded to a Google Drive link that I have posted on the Discord. You're welcome to test it, and confirm that the build works for you.

[cavejonhon]

I tried the 1.0.11 build from google drive. I am still crashing, but it seems to be unrelated to trains now. I'll post the crash dump here just in case it still is relevant to this. I included a bit before the actual crash. It is right after a getProdStats request, which I noticed that was another problem mentioned recently.

[2024.10.18-10.10.41:387][386]LogExit: Executing StaticShutdownAfterError

[Chaotic]

Is there a new official version coming for this fix? I was running into the issue the other day (but haven't tried the on on drive yet).

[porisius]

I would appreciate more looking at the test build in case there is another bug. I just got back from vacation, so I am trying to get caught back up on everything. I am looking over the two PRs and seeing about the Drone Info before release.

[saffronjam]

Adding another crash on /getTrains here for reference.

I could not reproduce this again by just reloading the save and requesting /getTrains, so it could a bit higher-level issue.

Version: 372858, IsEditor: No, IsPerforceBuild: No, BuildConfiguration: Shipping, Launcher: Steam, NetMode: Listen Server, IsUsingMods: Yes, IsSaveGameEdited: No
