Koni Marti 65ae87a524 threading: honor user-defined sort criteria
Apply the user-defined sort criteria to the message with the highest
uid in a threaded discussion. Restore the default sort order when
leaving threading mode.

Commit 7811620eb8 ("threading: implement on-the-fly message
threading") introduced message threading with the threaded messages
being only sorted by their message uids irrespective of the defined sorting
criteria. It did not restore the default sort order either.

wagner riffel 55ae3d2cab maildir: fix data race in maildir worker
Fix a data race due dirInfo pointer being read in the main goroutine
by NewMessageStore and written in the anonymous goroutine launched in
Worker.getDirectoryInfo.

To address the issue raised in https://todo.sr.ht/~rjarry/aerc/16, we
use readdir(3) once, parse and cache its results, this replaces
go-maildir library Dir.Flags based  stat(3) and filepath.Glob
causing the issue when N (emails) is large.

Koni Marti 7811620eb8 threading: implement on-the-fly message threading
implement message threading on the message store level using the
jwz algorithm. Build threads on-the-fly when new message headers arrive.

Use the references header to create the threads and the in-reply-to
header as a fall-back option in case no references header is present.

Does not run when the worker provides its own threading (e.g. imap
server threads).

Include only those message headers that have been fetched and are
stored in the message store.

Koni Marti 05ad96a30c imap: improve reconnect stability
improves the robustness of the imap reconnect feature which was
introduced in commit beae17a6da ("imap: auto-reconnects on connection
error").

If a connection error is emitted, the message list is cleared and a
corresponding error message is shown in the ui. Status bar is updated as
well. Upon reconnect, the directories and the message list will be
re-fetched (same behavior as the connect command).

Reconnect can be enabled and disabled with the connect and the
disconnect commands.

Robin Jarry 622802d3a5 maildir: defer the count of recent messages
Since commit 01c96e78df ("Update DirectoryInfo handling for maildir"),
flags are checked for every message of a folder when entering it.
Iterating over all messages of a folder takes a long time for large

Only count the number of messages and state that the directory info
counts are not accurate. Defer the parsing of message flags in
a goroutine to have a more responsive UI.

Koni Marti 022bf1a11f imap: fix panic when sending multiple connect cmds
fixes the panic when the user sends multiple connect commands and is
already connected. The panic is caused by closing an already closed
channel. This happens when the idle re-init code is not executed, e.g.
when there's a return statement in the switch block.  A defer func()
before the switch block will prevent this. The existing behavior of only
creating a new idleStop channel when properly connected is preseverd.

Kalyan Sriram 402612fd97 notmuch: allow sort by file order
When using the notmuch backend, it often makes more sense to sort
folders (actual virtual folders, or queries) by the order specified in
the query-map file, rather than alphabetically. This patch introduces a
configuration option (disabled by default) that allows this.

Additionally, due to the notmuch backend previously using maps (which
are order-undefined) to store the list of queries, default query
selection on aerc startup fluctuated. This patch fixes that by using
slices to store query order.

Reto Brunner 1687e558d3 notmuch/maildir: remove double emit of the dirinfo
There was some bug which could be worked around by double emitting an event.
However that proofed to be brittle:

We send the first message here from the worker goroutine:
https://git.sr.ht/~sircmpwn/aerc/tree/a5553438/item/worker/maildir/worker.g=
o#L306

Then Tick() is waked in the main goroutine and calls ProcessMessage:
https://git.sr.ht/~sircmpwn/aerc/tree/a5553438/item/widgets/account.go#L100

ProcessMessage in the main goroutine reads types.Message state with
msg.getId() and msg.InResponseTo():
https://git.sr.ht/~sircmpwn/aerc/tree/a5553438/item/worker/types/worker.go#=
L74-76

Meanwhile in the worker goroutine we call PostMessage for a second
time with a pointer that points to the *same* previous message that
ProcessMessage is reading:
https://git.sr.ht/~sircmpwn/aerc/tree/a5553438/item/worker/maildir/worker.g=
o#L306

The second PostMessage call makes writes to message while
ProcessMessage in the main goroutine is possibly reading:
https://git.sr.ht/~sircmpwn/aerc/tree/a5553438/item/worker/types/worker.go#=
L59

This led to a data race in the event loop

Jeff Martin 0acb28645f handle message unknown charset error
This change handles message parse errors by printing the error when the
user tries to view the message. Specifically only handling unknown
charset errors in this patch, but there are many types of invalid
messages that can be handled in this way.

aerc currently leaves certain messages in the msglist in the pending
(spinner) state, and I'm unable to view or modify the message. aerc also
only prints parse errors with message when they are initially loaded.
This UX is a little better, because you can still see the header info
about the message, and if you try to view it, you will see the specific
error.

Reto Brunner c846307144 base models.Address on the mail.Address type
This allows us to hook into the std libs implementation of parsing related stuff.
For this, we need to get rid of the distinction between a mailbox and a host
to just a single "address" field.

However this is already the common case. All but one users immediately
concatenated the mbox/domain to a single address.

So this in effects makes it simpler for most cases and we simply do the
transformation in the special case.

ARaspiK fe1cabb077 Add support for :rmdir
The `:rmdir` command removes the current directory (`-f` is required if
the directory is not empty).

This is not supported on the notmuch backend.

An issue with the maildir backend is that some sync programs (e.g.
offlineimap) may recover the directory after it is deleted.  They need
to specifically be configured to accept deletions, or special commands
need to be executed (e.g. `offlineimap --delete-folder`) to properly
delete folders.

A danger of using this on the IMAP backend is that it is possible for a
new message to be added to the directory and for aerc to not show it
immediately (due to a slow connection) - using `:rmdir` at this moment
(with `-f` if the directory already contains messages) would delete the
directory and the new message that just arrived (and all other
contents).  This is documented in aerc(1) so that users are aware of
possible risks.

Reto Brunner f1a0fd20d6 improve date parsing for notmuch/maildir
If a message date would fail to parse, the worker would never receive
the MessageInfo it asked for, and so it wouldn't display the message.

The problem is the spec for date formats is too lax, so trying to ensure
we can parse every weird date format out there is not a strategy we want
to pursue. On the other hand, preventing the user from reading and
working with a message due to the error format is also not a solution.

The maildir and notmuch workers will now fallback to the internal date, which
is based on the received header if we can't parse the format of the Date header.

The UI will also fallback to the received header whenever the date header can't
be parsed.

This patch is based on the work done by Lyudmil Angelov <lyudmilangelov@gmail.com>
But tries to handle a parsing error a bit more gracefully instead of just returning
the zero date.
