Log: Couldn't select folder "DeltaChat"

[ChrisPHL]

Dear DC developers,

since Version 1.44.0 my DC instance is not able to receive any message. If I downgrade (uninstall, install v.1.42.6 and restore from backup) all new messages are received as normal.
I would expect the reception of new messages in the current version as before in version 1.42.6. I doubt the fault is related to the access to DeltaChat folder..?
For clarification I append some snippets of the log file.
Please feel free to contact me for further information or in case you need help trying a new debug version... with my account. I could even create an email-account on the same server my email-account is hosted on so you could try out/debug new code if needed.

Would be nice if we can solve the problem together. 😊
Thanks for your great work over the years so far! (I met some of you guys years ago on CCC 😎)

It looks like the "DeltaChat" folder was renamed to "INBOX.DeltaChat" because you have configured_mvbox_folder=INBOX.DeltaChat, but the log tells that there are some existing messages having imap.target=DeltaChat so Delta Chat tries to create this folder in store_seen_flags_on_imap(). Then the server doesn't allow to create the "DeltaChat" folder, but that's the second problem that can be fixed by always trying to create/select a fallback folder with name "INBOX{delimiter}DeltaChat".

EDIT: Need to understand how the older version works then. Looks like a regression though the scenario looks tricky and maybe the older version worked just by chance.

EDIT: @ChrisPHL would be good if you can check if the folder indeed was renamed. Otherwise i don't understand how Delta Chat has run into this. And what is a posiible fix, fixing up imap.target if the folder doesn't exist and can't be created? Not really a question, first need to understand the scenario.

[ChrisPHL]

Thank you so much for your detailed answer!
I'm using an email account that is dedicated to my Delta Chat communication. This account is pretty old, older than DC but when DC came up I just used this account. So you can consider me an early DC adopter. 😉 I can assure that I never renamed any folder manually. Only thing that may be interesting in this case could be a service provider change in January 2023 (the domain where my email account is located was moved to another provider). Since I also use Thunderbird on my PC to read DC messages in addition to DC-AppImage-Client I'm not sure if Thunderbird never changed anything... 🤷‍♀️ but at least I didn't...
Considering your first Edit seems the best way to solve the issue permanently. 👍

Please don't hesitate on case of any further question.

Kind regards
Chris

I just saw this comment mentioning your MR.
Is there a download of an installable APK file from your branch that I could use for a qick test?

[iequidoo]

I added a second commit that should make Delta Chat working with your database, but it's still not a complete fix because messages with incorrect imap.{folder,target} column values ("DeltaChat" instead of "INBOX.DeltaChat") will remain in your db. To build Delta Chat Android APK you should follow steps in https://github.com/deltachat/deltachat-android/blob/main/README.md. Personally i was building it using Nix and Docker, but there are other ways. Maybe an easier way is to create in the https://github.com/deltachat/deltachat-android repo a draft PR using the core with the fix, then you can download the APK file from that PR

[iequidoo]

@ChrisPHL, the PR is merged so you can use the core from the main branch. Or i can try to build the APK a bit later. Still need to think how to fix up your db and if this should be done manually for this particular case or fixed somehow in the code.
