[iOS 15.3] Application immediatly close on sync with s3 target

[vfricou]

The sync process to S3 bucket cause an application close on iOS.

When S3 synchronization is configured, at sync process start, the application immediatly close. Even at application restart.
The issue stay in place after an application full uninstall/reinstall.

Tested with S3 target on AWS, Scaleway or Minio (through reverse proxy or not)

Environment

Joplin version: 12.6.2
Platform: iOS
OS specifics: iPhone 12 - iOS 15.3 (problem started on 15.2)

Steps to reproduce

1. Install Joplin from store
2. Configure synchronization on S3 with existing bucket target
3. Start synchronization

Describe what you expected to happen

It’s expected to synchronization ran normally without application close

Logfile

No relevant log available on iPhone, and no relevant log with minio target (no minio server relevant log)

I’ve found error exception with iPhone connected to my Mac :

Hi!

I'm on 15.2.1 now with the latest joplin app (12.6.2) and not getting this error. I also wrote the updated S3 code in Joplin.

• On your Joplin iOS app -> Configuration what version of the DB are you on (I'm on 41)
• Are you inputting a region in the joplin S3 settings?
• Is Force path style on or off?
• Are you able to run a check synchronization configuration or does that trigger the crash?

Hello!

I'm on iOS 15.3 now with the same lastest joplin app(12.6.2) and have the same error. My S3 backend is build with minio.

By the way, on my MacOS 12.0.1 with joplin 2.5.12 and my Android 11 with joplin 2.3.4, this sync method is all OK.

machine	machine version	joplin version	status
iOS	15.3	12.6.2	closed when sync
MacOS	12.0.1	2.5.12	fine
Android	11	2.3.4	fine

Hi,
Replies below.

• On your Joplin iOS app -> Configuration what version of the DB are you on (I'm on 41)

I'm on 41 too

• Are you inputting a region in the joplin S3 settings?

Yes region is defined

• Is Force path style on or off?

Force path style is on

• Are you able to run a check synchronization configuration or does that trigger the crash?

Yes I've done sync test with ok result and this no close app crash.

[leematos]

Thanks, I'll see if I can repro in a test env.

Can you add [iOS] -> [iOS 15.3] to the title for clarity?

[leematos]

I attempted to test this tonight but I need a full OS update to get to the 15.3 simulator... I won't be able to get to that until at least next weekend. :(

I have the same issue with latest Joplin version on iOS.
Is there a workaround?
Thanks a bunch for an awesome app

I was trying to migrate from Joplin server (self hosted) to S3 (also self hosted), but got the same result :

• When configuring S3 sync settings in the iOS app, the sync test says that everything is OK and successful. The app doesn't crash
• But as soon as Joplin tries to do the first sync, it crashes. Then, when starting Joplin again it crashes after 2-3 seconds. The only way to "recover" is to remove and reinstall the app so all settings are reseted.

My config :

• iPhone 13 Pro on iOS 16 beta 4
• Joplin 12.8.1
• The S3 bucket is configured on a self hosted MinIO docker instance

It doesn't seem to be linked to the iOS version as OP reported this on iOS 15.3.

Also, the desktop app on my Mac sync correctly to this same S3 bucket.

Some more info :

• Yes region is defined
• Force path style is on
• DB version displayed in Joplin settings is v41

For now I just reverted to using my sefl hosted Joplin server. I was doing this for educational purpose.

Let me know how I can help.

[leematos]

I think this is a problem with something we send and what MinIO expects/returns

Can you get logs from the minIO side and see if we can see the requests it received?

Is your minio server by chance internet accessible that you could get me a test user set up?

I suspect it's the same as #6047

[lbalogh]

Well I checked the trace logs of MinIO but I don't see any errors. I haven't found YET how to export these logs in text format, so are are some screenshot of what happens when I launch the app on my iPhone :

Maybe there's a way to have more advanced logs... I'll have to investigate.

My MinIO server is not exposed to the outside, but I can send you a temporary access so you can check by yourself. The connection goes to a reverse proxy though, but the result is the same : even when I try locally by configuring the S3 URL directly using a local ip (192.168.1.xxx) Joplin also crash, so I don't think it's linked to the reverse proxy

[lbalogh]

Let me know how I can send you the S3 bucket configuration so you can try by yourself ;)

[leematos]

@lbalogh find dot creativity at github username dot com -- i don't expect to have a chance to look at this until this weekend as I don't have a recent dev env set up.

[lbalogh]

No problem. I sent you the information for the test S3 bucket so you can reproduce the crash. Note that as you won't be able to test it before the week-end, I'll only enable access from outside at the end of the week. Tell me if you need it before

[chaosye0]

the latest joplin app on ios still crashed when sync with s3 (minio)

[leematos]

@chaosye0 -- Any more insight? Logs? anything?

[chaosye0]

@chaosye0 -- Any more insight? Logs? anything?

app closes immediately when s3 sync started, and left one .locks folder in my joplin bucket. After I deleted the .locks folder, the windows joplin app then sync without error.
The ios joplin app starts syncing then closes, when I open it, and left a folder named as ".locks". It can be reproduced in my ios 17.2.1.

Hi there! I've got same problem with my s3 minio instance. Here is a console logs from my iPhone12

Thanks! Any chance you have corresponding s3 minio logs as well for that time period?

Basically in the logs before this I see an SSL connection being attempted, it appears to abort (posibly normal, maybe wrong ciphers) I see another SSL attemption connected, similar messages, and then I see a string of 200 requests, and then this 204 with an exception saying "client is gone". I think Minio logs would help to see what minio was doing with the connection and why.

Beyond that, if you have a test bucket you can set up in minio without https I might suggest trying to sync that and see if the behavior is the same or different. I'm not sure if this is a "malformed request" that minio doesn't like or "SSL issues" that minio doesn't like.

[n3b0r]

This is also happening to me when using third-party S3 providers like iDrive.

Does there exist any temp workaround to run Joplin on iOS while this is addressed?

Thanks

Hi there! Sorry for delay. This log from minio(mc admin trace myminio -a -v). It all starts with launching the Joplin application on my iPhone.
