[mu bug] Get error messages when mark message to read.

[zw963]

Describe the bug I have many unread message in my Maildir.

I want mark all don't care message as read, following is my process:

1. pressing s in mu4e
2. Set filter in minibuffer.(filter to show only unread messages with others condition)
3. search result.
4. pressing W disable show threads
5. run (mu4e-headers-flag-all-read), mark all result as read.
6. pressing g to rerun this.
7. repeat step 5, 6

After i repeat several times, special, when current mixin with read + unread, always get error like this:

error in process filter: [mu4e] Error 32818: '' is not a valid maildir error in process filter: mu4e-error: [mu4e] Error 32814: target maildir must be empty or start with / () error in process filter: [mu4e] Error 32814: target maildir must be empty or start with / () error in process filter: mu4e-error: [mu4e] Error 32818: '' is not a valid maildir error in process filter: [mu4e] Error 32818: '' is not a valid maildir error in process filter: mu4e-error: [mu4e] Error 32814: target maildir must be empty or start with / () error in process filter: [mu4e] Error 32814: target maildir must be empty or start with / ()

Even, it will broken my mu index, which cause following error:

 ╰─ $ mu index
error: Expected block 48951 to be level 2, not 0

But, those issue i remember not happen when i use 1.6.X (at least, seledom happen)

i have to init and reindex all messages. (0.2 million)

The really big issue is, when error happening, all error message will output to minibuffer continously, which cause for a long time, any mu query command failed, i have to wait for several minutes for all error is output done, then i can continue the above process, but same error happen again quickly.

Environment Arch, mu + mu4e 1.8.6

Hmm, I'm unable to reproduce this.

[djcb]

Does this still happen with 1.10.x?

[zw963]

I use 1.8.9 for a while, though, check email frequency not high anyway.

never found this issue again.

I doubt this issue only happen when work with offlineimap, but i switch to use getmail.timer systemd service for a while, this is a single method email retriever.

I compiled a 1.10.0 just now, and do a quick test, it seem like works, thanks very much!

Great - thanks!

[zw963]

Great - thanks!

Hi, @djcb , i get new error message when update to 1.10.0, please check following screenshot.

It will keep happen when mark as read for some special message, that is, if this error raise on one message, it keeping error.

It happen several times when i try to use 1.10.0 several days ago.

BTW: this error never happen when use old 1.8.9.

Thanks

Hmm, that sounds like the kind of error you'd get when message change behind mu's back, e.g. with offlineimap / mbsync, other mail retrievers. I did push some changes for better error messages.
