Nightly crashes when trying to load a sequence

[kevinsaucier]

Just downloaded and installed the latest nightly (2024/05/13). I was working on a previous nightly (from Thursday, maybe) and it was working fine. Needed to reboot my computer so figured I'd update my xLights. Installed over the top of the old nightly and opened it up. It opens fine but, when trying to load the sequence I was working on, it crashed (I can see the crash window outline come up but it doesn't populate and then the program is gone). Tried again, same issue.

Full uninstall/reinstall (which is painful because it apparently removes the registry entries - that should be an option wink wink). Tried to open the sequence. Same issue. Tried a different sequence. Same issue. Tried a blank sequence. Same issue. Seems to crash as soon as it tries to load the model list. Musical/Animation. Doesn't matter. 40fps/20fps. Doesn't matter. 'All Models' or a view when creating the sequence. Doesn't matter.

It's not creating a dump file so I'm not sure how else I can help to troubleshoot. Guess it could be just me but figured I'd note it since it's probably not.

On a related note........is it possible to get a previous 'nightly' EXE or does Github only store the latest one? Of course, I deleted the previous downloads and I only keep one copy of the nightly installed. since it usually works well enough. 🤦‍♂️

You may need to be logged in to see the Assets... Try this anc let us know if still and issue or user error... :) https://github.com/xLightsSequencer/xLights/actions/workflows/win_nightly.yml

LOL, thanks. Grabbed #900 from here - https://github.com/xLightsSequencer/xLights/actions/runs/9048978743

Installed and opened my sequence no problem. Went back and installed the latest nightly over the top and back to crashing. Debug package attached.

Well all we have there is the show folder layout. I can open that and create a new sequence just fine. I'm on a Mac though.

Yup, that's all it takes to crash. It's not a specific sequence, just creating a new sequence does it. Seems to happen as soon as it tries to load the list of models but it's hard to tell since the whole app just disappears.

Same here .. downloaded nightly. Open sequence .. count to about 5 and poof it just closes out. WIndows - my layout.

Hooray! It's not just me! No user error here @cybercop23 ! 🤣

This is repeatable .. every time I open a sequence with this Nightly.. And now I cant open xlights at all :-(

A bit of a guess here but on bootup.. GetActiveModels() returns nothing.. the models.front() returns nothing.

    auto models = GetActiveModels();
    bool single_model = models.size() == 1;

    // if single model make sure the effect setting is on correct head...if not move it
    auto model = models.front();

I see this .. perhaps it needs to be higher?

    // Set current timing track in Dimmer window
    if (model == nullptr) return;

[derwin12]

This gets me by .. ( I dont have moving heads in this layout) btw bool single_model = models.size() == 1 << is that ANY 1 model or do you mean if you only have 1 moving head model?

[AzGilrock]

Thanks for tracking that down. I see what happened. I moved that "auto model = models.front();" line outside the if (single_model) section so that I could access it lower for the timing track. Well the single model flag was preventing it from executing when the count was zero. I pushed your fix in. Just not sure why it wasn't crashing on mine. That's what is frustrating when the different OS's react differently.
