Crash on mac launched via editor

#1

@britzl @jcash

I have got a crash on Mac while playing the game launched via the editor. This was totally unexpected to me, I don’t see any error report in the console (but the call stack). Nothing special was going on. Here is the crash dump file:

_crash_2103292216.zip (2.9 KB)

I am using: defos, fmod and playfab. But I would say I was not using them at all in the moment of the crash, also sfx and music were disabled.

Many many thanks for any help!

Ciao!

The callstack (opening the _crash file in a text editor):

The callstack looks ok (valid), so I trust it.

The issue is http request related (the dmHttpService::HandleRequest).
Since http requests work most of the time, I think something more special occurred, like the request timed out.

In the 1.2.181 BETA we fixed a number of issues related to the http.requests, and I think #5672 might fix this issue.

On a related note, we’re also considering removing the cares library altogether, but that won’t happen until the 1.2.182 at the earliest)

@jcash Thank you so much for the interpretation of the call stack and the crash!

Indeed, now that you pointed me in the right direction, I was uploading some big files while the crash happened. So the internet was slow (not the best speed here) and probably the playfab player login timed out.

I hope that #5672 may fix this as you think. Otherwise I have to prevent the timeout event (how?) if the internet connection of a player is slow or there is no connection at all.

Thanks again!

Ciao!

You can test using the beta build found here:
https://d.defold.com/beta/

Note that there is a file format change in there,.So, to make it easier, make sure you already have your data checked in before using the latest editor with your project. That way it will be easy to revert those fileformat changes after testing.

Thanks! But I am not in a hurry about this:

  1. the leaderboard (hence playfab) is disabled in the first release for Switch, just to simplify our life with submission to Nintendo; we will make an update later with the leaderboard

  2. the PC / mobile releases will be after the Switch release.
