So, https://github.com/wordpress-mobile/WordPress-iOS/issues/12331 turned out to affect only apps running on Japanese.

This issue in particular seems to be related to this other ticket: https://github.com/wordpress-mobile/WordPress-iOS/issues/12028

I tried testing with WPiOS 13.0 (app store version) on iPhone 6S iOS 12.4 and the app did not crash on startup in my test, so I'm looking for any details about how to trigger the crash that I might be missing when testing from my end.

Noting the details from https://ios.forums.wordpress.org/topic/app-crashing-after-update

Recently I Updated My WordPress App to Latest Version in iPhone 7 and After that Whenever i Open App it Just Crash Instantly. Like - I Clicked on WP App>> It Shows Dashboard for 0.5 Seconds>> Blackout for 0.5 Second and Closed without any Notification. I Tried to Restart my Device but no Luck.

Noting some details from 6166545-hc

New iphone upgrade - WP App initiation just produces frozen blue screen with W in the middle. Computer is fine but I need to have both working.

Followed by:

On the phone I have 2 WP logos. One takes me straight into stats and via that to all the rest. It is light blue and works (so I have that). No idea if the upgrade has been applied. This is the portal I generally use.

The other is the basic WP portal, now dark blue (I assume from the upgrade)

I clicked on it today. I got the frozen screen I described. I couldn't get past that so I went to the App itself where I saw the upgrade details (unaware before that)

Sounds like they have two installs? Interesting. Maybe one is a TestFlight beta install. 🤔

Confirmed they are using iPhone 7.

cc @aleone89 in the future can you include a teeny bit more detail when reporting issues mentioning internal references such as 6166545-hc on issues like this one? It's super helpful even if you just copy a short quote from the problem report or any quick/relevant details you have like device/app version or type of site! Thanks tons!

Oof. Looks like there's not much chance to get app logs in these cases, but @chaitanyamsv if by some chance the app starts working long enough for you to get to the Profile > Help & Support > Activity Logs screen, please add a copy of the logs and send them our way via support in the app or in #cellular-happiness on Slack! 😊

For reports of these cases, we'd like to confirm:

Did this happen for you only after upgrading to version 13.0 of the WordPress app?
What is your iOS version?
What is your device language set to in Settings > General > Language & Region?

If anyone experiencing this is able to get to the logs in Profile > Help & Support > Activity Logs, please send us a copy in the Contact Us screen in the app or by sending to [email protected]. Thank you!

I can see from sentry that this happens on -[CommentService mergeHierarchicalComments:forPage:forPost:] but I haven't been able to figure out any possible cause. My guess is that it could be related to a specific comment being synced, and not device-specific, so it would be interesting if we could try to reproduce this with any of the affected accounts.

Noting the details from https://ios.forums.wordpress.org/topic/wordpress-app-crashing

I am running iOS 12.4 on an iPhone 5s.

I can’t remember which part of the app I was using but was working perfectly prior to the most recent update. The app stays on the start up screen for around 15 seconds before closing.

Just to let you know that deleting the app then reinstalling it fixed the issue, hopefully this might work for anyone else having this issue.

I couldn't access the activity logs before I deleted the app as I couldn't access any part of the app unfortunately.

Working with another report in #2296429-zen

A blue screen appears as though it’s going to open, then goes. Double clicking the home button shows it’s there, but trying to open it from there has just the same effect.

This person has an iPod Touch running iOS 12.3.1 and WPiOS 13.0, and this crash began after updating to 13.0.
In addition, they're running the TestFlight public beta on an iPad, currently WPiOS 13.1, and the crash is occurring there as well.
I'm asking them to clarify the device language.

2296429-zen from above came back to let us know that their devices updated to iOS 12.4.1, and their WPiOS apps on both devices are still crashing.

thehenrybyrd on 1 Sep 2019

Unfortunately we are still investigating this issue. We haven't been able to replicate it, but we are putting more logging and mitigation fixes in place. For now the only thing we can tell users is to uninstall and reinstall the app. If anyone is seeing the issue after following those steps please ping me.

elibud on 2 Sep 2019

That's been my experience too. WordPress app stopped crashing once I uninstalled the existing version (13.1) and installed the updated version (13.1.1) on my iPhone 7 running on iOS 12.2.

Simply updating the app did not help; I had to uninstall the current version and install the latest version.

chaitanyamsv on 2 Sep 2019

I'm seeing a crash on startup happen for account design5279 with WP Internal 13.1.0.20190819 on both my iPhone and iPad right after updating to iOS 13.1 beta 4 (from 13.1 beta 3). I also have the app store version installed on the same device and that one is working normally—the app store version is a fresh install though, I deleted and reinstalled before noticing the crash-on-startup issue in WP Internal.

^{Tested with WP Internal 13.2.0.20190827 (HockeyApp) on iPhone 6S iOS 13.1.}

@jklausa @jkmassel I followed the previous conversation you had with @chaitanyamsv in Slack about pulling files from a local backup and sent them to you in the same thread. Here are the steps I followed to get the backup:

Follow https://support.apple.com/en-us/HT203977#itunes to make a backup.
Download and install iExplorer.
Give iExplorer full disk access (follow the instructions that pop up).
In iExplorer on Mac, go to today's backup > Backup Explorer > App > org.wordpress.internal.
Export the folder, zip it, save it somewhere online with a share link.

Note: my backup org.wordpress.internal folder is only 1.7 MB.

@designsimply I don't see any crashes that match this version in sentry. Can you look for them in your device and share, just to make sure it's the same crash?

@koke certainly! I zipped up everything from the ~/Library/Logs/CrashReporter/MobileDevice folder for my device and sent it to ya in Slack.

Aside: I also looked for anything related to WP Internal at Settings > Privacy > Analytics > Analytics Data on the device directly but didn't see any file names that looked related.

Used this app infrequently for blog updates and it always worked fine. As of two weeks ago, it stopped working. When opened, the app briefly displays, then crashes to desktop on my iPad. No amount of updating, reinstallation, or patience while waiting for a fix has worked. Will have to begin using a different product to access my Wordpress site.

I still don't know why this happens but at this point:

The app tried to open the core data database and it was incompatible, triggering a migration
The migration has failed for some reason
As a last resort, the app tries to back up the existing database, remove the file, and try again
The NSPersistentStoreCoordinator is still failing to add a persistent store at that URL, even if it should be creating a new clean one.

Worked with @leandroalonso on this for a while now but we failed to find the cause. We saw the same exceptions described in https://github.com/wordpress-mobile/WordPress-iOS/issues/12338#issuecomment-541032550 but there are not enough details. As for the database shared in https://github.com/wordpress-mobile/WordPress-iOS/issues/12338#issuecomment-532808481, we posted our findings in https://github.com/wordpress-mobile/WordPress-iOS/issues/12028#issuecomment-557591559.

We also tried to simulate a locked database file but that yielded a different stack trace.

updated your iOS app, keeps crashing on startup, can’t even open it.
Version 13.6 on iOS 13.1.3, iPhone 6s

This came up in beta testing for 13.7:

Opened a push notification right after updating to 13.7. It crashed on launch, but the second launch seemed fine

App version: 13.7 (13.7.0.0)
Device: iPhone XS
iOS version: 13.2

designsimply on 4 Dec 2019

I don’t get any error message when using the app but after taking a long time to load it just closes down. I get notifications and I can see a pic if I look at all of my open apps but pressing on it means it just refuses to load. It’s baffling as it happened suddenly on my phone first and later my iPad.

App version: 13.7
iPhone 5s and an iPad Air both running iOS 12.4.3.
The capacity of my iPhone is 64gb with 46.27gb free.
The capacity of my iPad is 16gb with 1.15gb free.

These ones in particular were most likely caused by this other issue: https://github.com/wordpress-mobile/WordPress-iOS/pull/13155

diegoreymendez on 3 Jan 2020

I hit this issue on an iPad Pro 11" last night – the app was up-to-date, so the issue was certainly not related to core data migration.

I hit the "open a notification and the app crashes" issue, after which the app was stuck in a crash loop. That makes me think that the app might've been trying to restore the view it was attempting to display when it crashed over and over. The PR merged by @diegoreymendez may resolve this issue in addition to the crash-on-open-notification issue, but let's wait and see – running develop on the device from Xcode broke the crash loop and it launched properly, so the issue _may_ be resolved!

Just adding my info here in case we need to do further debugging.

Another piece of information from the results of the track we implemented in https://github.com/wordpress-mobile/WordPress-iOS/pull/12995:

We've been receiving some track information but they're all related to people in our team (probably running the release process, tests or something like that). You can see the data here. Filtering to remove occurrences from our team results in zero occurrences of this issue.

If we didn't receive any new report about that issue I'd assume that's fixed, as @jkmassel pointed.

Also, we can remove this tracking from the app for the next version. What do you think @jkmassel?

leandroalonso on 10 Jan 2020

@leandroalonso – I agree that it's probably ok to remove this, but I wouldn't mind doing so once this issue is closed – it's possible we have > 1 bug, and if there was no migration as part of the newest release, it's possible that bug remains (but I'm...kinda(?) confident it's ok!)

I think...remove it for now, and if we see other issues, we can just pop it back into another release since we trust the code :)

@leandroalonso – update:

I took a look through the details again, and these are _probably_ live issues, not related to A8C debugging.

This error:

Can't initialize Core Data stack: -[ContextManager persistentStoreCoordinator] (/Users/jeremymassel/Projects/WordPress-iOS/WordPress/Classes/Utility/ContextManager.m:284) Der Vorgang konnte nicht abgeschlossen werden. (NSSQLiteErrorDomain-Fehler 13.) | userInfo: ["NSFilePath": /var/mobile/Containers/Data/Application/CE8EB4CC-0A59-4DCF-AC6D-CC023E9E990A/Documents/WordPress.sqlite, "NSSQLiteErrorDomain": 13]

is odd, because I don't use my device in German, and we don't send Sentry errors for debug builds.

I suspect this is a real user, and the filename is just what it is because I built the hotfix on my local machine.

I now think we should consider these real crashes and react to them appropriately :(

jkmassel on 10 Jan 2020

@jkmassel Hmmm... that's bad.

I was talking with @shiki and most errors refer to NSSQLiteErrorDomain: 778 (errors 13 are related to disk full).

From SQLite documentation:

(778) SQLITE_IOERR_WRITE
The SQLITE_IOERR_WRITE error code is an extended error code for SQLITE_IOERR indicating an I/O error in the VFS layer while trying to write into a file on disk. This error might result from a hardware malfunction or because a filesystem came unmounted while the file was open. This error should not occur if the filesystem is full as there is a separate error code (SQLITE_FULL) for that purpose.

The database exists, it can be read, but it can't be written. I still have no idea why this is happening. 😢

leandroalonso on 20 Jan 2020

That's interesting – IMHO we should handle the error 13 – Disk Full issue with a graceful message to the user? One weird way to potentially mitigate this would be to catch that error specifically, clear out WP's own local caches (for images etc), and retry the save? At least that way user data would be safely stored away?

The error 778 is really strange! It doesn't appear to be because of write lock contention (I was thinking maybe we were calling save from the wrong thread?), but I think that'd be error 15 (maybe?), but I'm not super confident about that.

I kind of wonder if it's a transient thing. In the same way we'd special-case a full-disk, WDYT about special-casing a 778 error and just retrying in order to see if it tends to be a temporary hiccup or a persistently broken DB? If the DB is just broken, we could present UI offering the user the option to rebuild their database – we should have all their credentials in the keychain, so just removing the DB and rebuilding from scratch should work well?

These are sort of off-the-cuff ideas that would take some time to implement, but WDYT?

jkmassel on 20 Jan 2020

@jkmassel Sorry for taking too long to reply.

On the error 13 – Disk Full: I wonder if the OS itself doesn't handle that when the app crashes (with the "Storage Almost Full" warning). My main concern is that we'll need to be aware and handle other cases (in WordPressAppDelegate for example) to prevent other parts of the app to access the database (which will cause a crash) — so it's not as simple as just showing a View. Thoughts?

On the 778: what's your idea? To retry right recreating the persistentStoreCoordinator right away?

@designsimply I wonder how many tickets we've been receiving of users complaining of the app crashing on the startup. Do you know?

If the number is low, probably it's just something temporary as @jkmassel mentioned and maybe the retry can be a good solution.

The newest update causes the app to crash. Worked fine prior to this update. App will open but won’t allow you to do anything and won’t show any traffic info. Have to delete the app and reinstall to get it to work again. Have to do this once a day or so since updating...

There haven't been any new reports of crash on startup in app reviews for 2020 to date, which is way cool!

designsimply on 20 Feb 2020

On the 778: what's your idea? To retry right recreating the persistentStoreCoordinator right away?

Yeah that would be my thought. Even throw in a jittery delay to retry it – IMHO the goal is to say "is this a transient thing the device can recover from, or is it a permanent failure?". Also – for this specific error, it might be valuable to try to find out what point this is happening. As a for-instance, do we know for sure this isn't a background crash happening while the user's device is locked? If the app launches in the background, is the storage locked? I don't know what data protection level we use for the DB, but I'd be curious about that. Also curious about if the app crashes and SQLite is trying to apply the WAL to recover and we come in trying to set up our Core Data stack at that time whether we'd have issues. Just a few more off-the-cuff thoughts – this is definitely a tricky one. Last thought – part of me wonders if this could all be resolved by adopting NSPersistentContainer and getting out of the "initialize the stack" business?

In terms of priority, I _think_ the main crash-on-launch issue we were hitting was the notification one, which was fixed in https://github.com/wordpress-mobile/WordPress-iOS/pull/13158, which is why we're seeing fewer user complaints now.

That background crash happening is a good idea. I wonder if that's really what's causing this. 🤔

Also curious about if the app crashes and SQLite is trying to apply the WAL to recover and we come in trying to set up our Core Data stack at that time whether we'd have issues.

The last time I looked at this, the WAL recovery happens when the persistent store is created during:

https://github.com/wordpress-mobile/WordPress-iOS/blob/052de444122a933bf5c27c71b1ed358f69852962/WordPress/Classes/Utility/ContextManager.m#L249-L253

So I think that routine is under our control. Everything should be happening in the main thread too last I checked.

part of me wonders if this could all be resolved by adopting NSPersistentContainer and getting out of the "initialize the stack" business?

This would be great. I believe the Core Data initialization stack is overdue for a refresh. Especially since we have that Core Data migration failing silently issue lurking around: #13014.

The App has been down for a long time, and every time you open it, you can't turn on every function. But the Internet is normal, and other apps can be used normally. Only Wordpress doesn't work, the page keeps turning but never opens. I hope to fix it soon, thank you! ~
