~rjarry/aerc#70: 
Two threading bugs

Using aerc-0.11 on Gentoo with the default config.

Here's a minimal maildir to reproduce it: http://0x0.st/oeTf.tar.gz Extract it somewhere ($HOME in the example) and temporarily add to your accounts.conf:

[Threading bug]
source = maildir://~/threading_bug
default = Inbox
from = dummy <dummy@dummy.net>

#1st bug

The todo.sr.ht discussion with subject "Re: ~rjarry/aerc#65: Charset handling in filters" isn't threaded at all, while it is on neomutt (without thread root).

#2nd bug

Resize your terminal windows to be something like 10 lines high and open aerc. The "[dev] Replace ranlib(1) calls?" thread isn't properly rendered until all messages have been displayed (by scrolling down or using G).

Thanks for reporting this and sending the messages to test! Much appreciated!

This discussion is not threaded because these messages lack the References header that aerc relies on for client-side message threading. Mutt seems to use the subject line when there is no References header available as a fallback.

We could consider bug #1 as a feature request for using the subject line when no References header is available.

Client-side message threading only applies to the messages that have been fetched (i.e. were loaded in the message list) for performance reasons. It does not thread your entire mailbox. If this is required, server-side threading would be the only way for now until we have a message cache for the entire folder available. Server-side threading can be done with IMAP servers that support the THREAD extension or with the notmuch backend.

I see.

What's the caching situation? Does it fetch/cache only what's visible or a specific block size? I could imagine setting that to say "threads will contain at least the last N days".

In any way, it should be able to thread more than what's seen, at least a few weeks; that's really the point of threads, to group messages differently from the rest, despite their time spread.

Well, beggars can't be choosers, as they say.

If you have caching turned on, messages which have been fetched (IE displayed) will be cached. You can set the max age of any item via cache-max-age. That said, just because it's in the cache doesn't mean it will now be threaded. Cached messages are only loaded when they need to be displayed.
