Work around mail.163.com not returning UIDNEXT on SELECT and STATUS

[fengguowudi]

• Operating System (Linux/Mac/Windows/iOS/Android):
• Delta Chat Version:1.42.0
• Expected behavior:
  successful login
• Actual behavior:
  could not read INBOX status Caused by: 0: STATUS (UIDNEXT) error for "INBOX" 1: io: Error(Error { input: [42, 32, 83, 84, 65, 84, 85, 83, 32, 34, 73, 78, 66, 79, 88, 34, 32, 40, 41, 13, 10, 65, 48, 48, 48, 56, 32, 79, 75, 32, 83, 84, 65, 84, 85, 83, 32, 99, 111, 109, 112, 108, 101, 116, 101, 100, 13, 10], code: TakeWhile1 }) during parsing of [42, 32, 83, 84, 65, 84, 85, 83, 32, 34, 73, 78, 66, 79, 88, 34, 32, 40, 41, 13, 10, 65, 48, 48, 48, 56, 32, 79, 75, 32, 83, 84, 65, 84, 85, 83, 32, 99, 111, 109, 112, 108, 101, 116, 101, 100, 13, 10] 2: Error(Error { input: [42, 32, 83, 84, 65, 84, 85, 83, 32, 34, 73, 78, 66, 79, 88, 34, 32, 40, 41, 13, 10, 65, 48, 48, 48, 56, 32, 79, 75, 32, 83, 84, 65, 84, 85, 83, 32, 99, 111, 109, 112, 108, 101, 116, 101, 100, 13, 10], code: TakeWhile1 }) during parsing of [42, 32, 83, 84, 65, 84, 85, 83, 32, 34, 73, 78, 66, 79, 88, 34, 32, 40, 41, 13, 10, 65, 48, 48, 48, 56, 32, 79, 75, 32, 83, 84, 65, 84, 85, 83, 32, 99, 111, 109, 112, 108, 101, 116, 101, 100, 13, 10]

Other clients are working normally. I use mailbox 163.

So we asked for (UIDNEXT) and the server returned nothing:

>>> ''.join(chr(x) for x in [42, 32, 83, 84, 65, 84, 85, 83, 32, 34, 73, 78, 66, 79, 88, 34, 32, 40, 41, 13, 10, 65, 48, 48, 48, 56, 32, 79, 75, 32, 83, 84, 65, 84, 85, 83, 32, 99, 111, 109, 112, 108, 101, 116, 101, 100, 13, 10])
'* STATUS "INBOX" ()\r\nA0008 OK STATUS completed\r\n'

I made a PR for imap-proto to allow parsing this: djc/tokio-imap#154

This is a bug in mail.163.com IMAP server.

there is a new android apk that should fix the bug:

🍋 download.delta.chat/android/deltachat-gplay-release-1.42.4.apk (android, overwrites existing gplay installs, keeps data)

EDIT: this is superseded by 1.42.5 from below

[fengguowudi]

However, the latest desktop version of deltachat, which is 1.42.1, still has this problem of not being able to log in.

Ok, we will need to fallback to using UIDNEXT=0 when STATUS does not return any UIDNEXT. Guess 163 simply does not return UIDNEXT for SELECT and STATUS, but messages still have UID.

Waiting for a new release of imap-proto from https://github.com/djc/tokio-imap that includes djc/tokio-imap#154

[link2xt]

This should be fixed by #5049 and in core 1.131.8, but let's keep the issue open until confirmed.

thanks all for helping fixing the issue! here is Delta Chat 1.42.5 that contains the recent fix #5049:

• 🍋 https://download.delta.chat/android/beta/deltachat-gplay-release-1.42.5.apk (android, overwrites existing gplay installs, should keep data)
• 🍉 https://download.delta.chat/android/beta/deltachat-fat-debug-1.42.5.apk (android, can be installed beside gplay)

@fengguowudi can you confirm that 163.com works with that version?

Sorry, I didn't make it clear what kind of hardware platform I used. I use IPhone and MAC. haha

Then we need a macOS desktop release with core 1.131.8 for testing.

In half an hour or so there should be a test build at deltachat/deltachat-desktop#3573

[Simon-Laux]

here is the test build: https://download.delta.chat/desktop/preview/deltachat-desktop-mas-3573.zip keep in mind that it is not signed, so needs to be allowed in the settings.

Perfect!

@fengguowudi Does this build work for you, can it login to mail.163.com? If so we can close the issue, otherwise please post the logs.
