Freezes occur on subsequent syncs over WebDAV

[stormlash]

Ever since upgrading to 1.7.2, I find that mobileorg.org regularly freezes while showing "Syncing Org-files: mobileorg.org".

Steps to reproduce:

1. Launch MobileOrg
2. Sync. It will sync the Org-files and complete successfully
3. Sync again. It will report "Syncing changes" and iterate through "mobileorg.org", "checksums.dat", and "index.org" before displaying "mobileorg.org" again and pausing. After a few moments, the label will change to "Syncing Org-files", but it will still be stuck on mobileorg.org. The only way to get past this screen is to force-close the app and resync.

Configuration:
iPhone 7+
MobileOrg 1.7.2
WebDAV sync (using https and a trusted self-signed certificate)

Did this also happen with the TestFlight version?

[stormlash]

No idea. TestFlight didn't notify me that a new version was available, and currently does not list me as an approved tester.

after upgraded to 1.7.2, I also have this issue.
Configuration:
iPhone 6s
MobileOrg 1.7.2
WebDAV sync (using https and a trusted self-signed certificate)

It seems it comes down to the self signed certificates.

There could be a different behaviour of iOS whether you're trusting the certificates or the CA. Trusting the CA is the preferred way.

We do need a test environment for that. I could imagine that using this docker repo could help to create (automated) tests for this issue.

PRs containing a test environment for this issue would be very welcome.

Could it be that the freeze only happens if changes on the iPhone are synced back to the server?

[stormlash]

Yes, I think that's quite possible - though I still see it even if nothing has changed on the iPhone.

[stormlash]

Ok - so I'm pretty convinced that this isn't related to certificate signing. I bit the bullet and swapped out my webdav cert with one generated through LetsEncrypt (which is automatically trusted by my iPhone), but the behavior is exactly the same: the sync freezes while displaying "Syncing Org-files".

Thank you @stormlash. That helps. I think I've found the issue.

When I updated the softwore to 1.7.2 version, I found the password feature can not use. 😭 😭 😭 I want to install 1.7.1, but IOS can not do it.

[mgmart]

@frapples, could you please give some details what your issue with password is about?

I would suggest to create a new issue with some details like iOS version, device, sync-method etc.
And of course as much detail as possible about the problem itself.

[webframp]

@frapples if you can give the details @mgmart mentioned that would help. We can also add you to the next round if TestFlight testing if you want to then confirm the fix

[stormlash]

I'm retracting my previous statement (which I've also deleted) - the fixes do address my issue. (I had been building off the MobileOrg fork, not the mgmart fork.) Sorry for the false alarm!
