I tried to reproduce this but for me the PWA opens and functions correctly. Can someone from QA try to reproduce this?

Thanks @AndiAJ ! Slightly different trace now but that's good info to keep looking into

This seems to be related to one of the most common signatures we are seeing on Nightly. Crash in [@ java.lang.IllegalStateException: at androidx.fragment.app.FragmentManager.ensureExecReady(FragmentManager.java)] bug 1641040

liuche · 2020-06-03T15:03:24Z

I'm going to dupe these to #10709, and I've moved STRs over bc these all have the same crash signature.

liuche · 2020-06-03T17:36:07Z

My bad, this is not the same bug as #10709, will do some un-duping.

…r finishing activities

…tivities

liuche · 2020-06-05T00:01:16Z

A few things we decided to do here for this bug:

for 5.1, made a 5.1.1 branch with a backout of d463696 - this means that [Bug] Need to go back 2 times when reading news from google to return to the inicial list of google news home screen #10718 will show up again in that build
on master, For #8374 - Don't recreate ExternalAppBrowserActivity or finishing ac… #11240 will add some crash checks and then we'll monitor to see if this crash decreases on Nightly

lobontiumira · 2020-06-05T09:36:53Z

I was able to reproduce the crash on OnePlus 5T (Android 9) on 6/5 Nightly build, with the following steps:

Sign in with valid credentials, with an old account.
Open several tabs (I had 10).
Share all opened tabs to all the connected devices.

Fenix either crashes or displayed the "Unable to send RETRY" snackbar.
I wasn't able to reproduce the crash on Beta 77.0.0-beta.2 (beta 5.1.1).

sv-ohorvath · 2020-06-05T14:32:44Z

I just repro-ed the crash on the original STR.

Have Fenix open in PBM homescreen

Background Fenix, Open PWA

Click away from main PWA scope to get toolbar

Select "Open in Fenix" from toolbar

Took me about 10-15 tries and then reproed a second time as well.

I got an ANR error with these steps on 77.0.0-beta2.

liuche · 2020-06-05T19:43:57Z

@softvision-miralobontiu I think this might be a different bug, but is also fragmentmanager related.

Stack trace here specifically is java.lang.IllegalStateException: FragmentManager has been destroyed androidx.fragment.app.FragmentManager.ensureExecReady(FragmentManager.java:4) androidx.fragment.app.FragmentManager.execPendingActions(FragmentManager.java:1)

liuche · 2020-06-11T16:06:45Z

Okay, here's some really consistent STR for me, at least 1/5 times.

Have open links in Private Browsing turned on
Open a link from another app (like from gmail)
Click back immediately (which will close PB mode bc it's the last tab)

The crash seems to happen when the PB system icon goes away.

ekager · 2020-06-18T13:54:55Z

@liuche with those step, I can repro on Nightly ~1/5 times, but I'm seeing a native crash (id bc606679-2815-41ea-9c81-e0b87e3809fb) , not this FragmentManager trace :/

liuche · 2020-06-18T17:09:41Z

I also just repro-ed this on the most recent Nightly, and I'm also getting a native crash, here's the socorro link: https://crash-stats.mozilla.org/report/index/c2d90164-a401-4802-bd6d-7658f0200618

Not sure why it changed.

It also looks like this has decreased in Sentry over the last couple of weeks: https://sentry.prod.mozaws.net/operations/firefox-nightly/?query=is%3Aunresolved+ensureexec&statsPeriod=14d

ekager · 2020-06-19T00:32:08Z

I was able to repro the fragmentmanager crash once, but of the 5 times I crashed with similar STR to #8374 (comment), 4 were the native crash

liuche · 2020-06-26T16:33:56Z

Do we know why this was a native crash sometimes - is it two issues somehow, and we're only handling one of them? Or the native crash is getting triggered racily.

sv-ohorvath · 2020-06-30T10:05:29Z

We've tried the steps to reproduce this on Fenix Beta 78.0.1 & 79.0.1 and looks like it is fixed. Marking this as fixed and closing.
