<![CDATA[Important: Unity 2019.X on mobile devices]]>Hi folks,

We've discovered what looks to be a pretty significant issue with using brainCloud for large packet requests on IOS devices. (edit: removed mention of Android as we have confirmed that it does not occur on Android devices).

The issue appears to be limited to Unity 2019.X.

More info here - https://getbraincloud.com/apidocs/warning-unity-2019-x-ios-issues/

We are constructing a minimal test app so that Unity can easily repro this issue (i.e. trying to take brainCloud out-of-the-test loop) - and then we'll submit the defect to Unity directly.

We'll keep you posted.

Paul.

We're haven't confirmed it yet - but this sounds hopeful.

Do we still need the @synchronized fix?

After every unity build to Xcode Project,

@synchronized (self) needs to be wrap the contents of writeMoreBody function.

I believe that's a patch to the Trampoline code that Unity generates.

Unfortunately, it's not so much a patch for brainCloud because those changes would need to be made by each app developer. (And I believe that you would need to re-apply the changes everytime you update Unity).

That said, it might be a short-term fix for someone how needs to release on 2019 now!

(I'll see if I can get a dev to try the fix and test to see if it works for us).

Paul.

We have a fogbugz id linked to our dev who reported it - but that seems to be private to him. It doesn't seem like it's their official defect.

Good to hear. Though, this still does not appear on their issue tracker, so can't vote on it. Do you have an issue tracker link I could access?

No ETA of course - but good to have the official recognition - hopefully a fix will come soon!

Maybe log into the Unity Forum and add a comment that getting that fixed is important to you.

It can't hurt to ensure that that issue is getting lots of attention in the forum.

Paul.

We're using 2019.x for a client app that uses brainCloud as a backend and we're not going to be able to downgrade. I don't think we've seen this issue, but nothing we're doing right now is very large with transferring data to the brainCloud that I know of.

We've only seen one Unity rep acknowledge the issue - with no indication of when (or for what stream) a fix might come.

And this issue is frankly huge. We haven't figured out any way to work around it.

We obviously wouldn't recommend anyone release a Unity app on iOS until this fixed!

I've added my voice to the issue in the Unity forum, and we'll keep an eye out for a time-frame. Since we intend to enter early-access next month, might just have to downgrade.

Thanks for the update!

Omar.

A bug report has been submitted to Unity regarding the UnityWebRequest usage on iOS devices on the Unity 2019 engine.

Bug Information : 1163795 | (Open) iOS - UnityWebRequest Errors - Large Packets - With Examples

Zipped Project : https://www.dropbox.com/s/ccybrg3tirpud0u/iosWebRequestFailures.zip

To Repro:

  • Networking Error observed on iOS devices. Run Example from Editor, Tests will commence immediately. UnityWebRequests of varying sizes ~100b, ~1200b, ~8000b, ~21000b and ~48000b are sent multiple times during the tests. The messages are sent to an echo endpoint, in order to confirm proposed send, and processed server data.
  • Logs are outputed to the screen, as well as the console for larger error packets.
  • All tests pass on Editor.
  • Build for iOS.
  • Open Xcode, Autosign the app, and build for device.
  • Tests fail at inconsistent moments in running tests.
  • Close the app, Re-run tests. Observe different failure conditions. Repeat.

Observed errors. No error, or data response returned. (0b response)
Observed errors. Corrupt data sent. (misaligned data)
Observed errors. Corrupt data sent, varying response from server (different sized response, shorter and larger response size)
Observed errors. CRITICAL networking error, where NO MORE network traffic is processed. (need to hard close the app for Network traffic to occur again)
