Set the SkipSort flag when sending directory infos for counting
purposes. Without this, the directory infos would trigger a directory
fetch which could bring the notmuch threads out of sync with the message
list. The notmuch backend sends these directory infos automatically
every minute.
To reproduce the weird cursor movement in notmuch's threaded view:
1. enter threaded view in notmuch
2. wait 1 min (until the auto directory infos are sent out)
3. move cursor around and notice how it jumps over threads

When opening unread emails from certain people (I won't name any names,

could not get section &imap.BodySectionName{BodyPartName:
imap.BodyPartName{Specifier:"", Path:[]int(nil), Fields:[]string(nil),

This does not occur for already read messages. This issue is similar to
the one that was fixed in commit 8ed95b0d2a ("imap: avoid crash when
replying to unread message").
This happens because the flags are updated in the callback that receives
the message itself. It causes the flag update to arrive in the same
channel/request. Ignore the messages that have an empty body (i.e. only
containing flag updates). This is inherently racy but there seems no way

Implement an mbox backend worker. Worker can be used for testing and
development by mocking a backend for the message store. Worker does not
modify the actual mbox file on disk; all operations are performed in
memory.
To use the mbox backend, create an mbox account in the accounts.conf
where the source uses the "mbox://" scheme, such as
source = mbox://~/mbox/
or
source = mbox://~/mbox/file.mbox
If the mbox source points to a directory, all files in this directory
with the .mbox suffix will be opened as folders.
If an outgoing smtp server is defined for the mbox account, replies can
be sent to emails that are stored in the mbox file.

Add option to cache headers for imap accounts. Cache db is located at
$XDG_CACHE_DIR/aerc/{account name}. The cache is cleaned of stale
entries when aerc is first opened.
Two new account level configuration options are introduced:
* cache-headers (Default: false)
* cache-max-age (Default: 30 days (720 hours))
The change in worker/imap/open.go is to set the selected directory. This
is required to access the UIDVALIDITY field, which is used in
combination with the message ID to form the key for use in the cache db.
The key structure is: "header.{UIDVALIDITY}.{UID}"
Where reasonable, cache does not stop aerc from running. In general, if
there is an error in the cache, aerc should continue working as usual.
Errors are either displayed to the user or logged.
All messages are stored without flags, and when retrieved have the flags
set to SEEN. This is to prevent UI flashes. A new method to
FetchMessageFlags is introduced to update flags of cached headers. This
is done asynchronously, and the user will see their messages appear and
then any flags updated. The message will initially show as SEEN, but
will update to unread. I considered updating the cache with the
last-known flag state, however it seems prudent to spare the R/W cycle
and assume that - eventually - all messages will end up read, and if it
isn't the update will occur rather quickly.
Note that leveldb puts a lock on the database, preventing multiple
instances of aerc from accessing the cache at the same time.

When moving/copying/deleting/archiving a message in imap, the RUE counts

implementation that recounts the entire directory and updates the
DirectoryInfo after one of these actions.
This patch implements a more efficient method of updating, and also
enables it to apply to IMAP without any additional requests. Upon
completion of the action, the counts are manually updated with the count
of messages in the action and recent and/or unseen states of those
messages. This is more efficient for maildir, because we aren't counting
everything in the store. For IMAP, we get the updates for free because
we are only performing the update after confirmation from the server

In the maildir worker we manually need to track the Recent flag in order for the
notification command etc to work.
Push that responsibility to the container, we must make sure to manually add the
flag though if one grabs the message info.
We frequently had issues with notmuch segfaulting and my guess is that this
was due to the garbage collection magic used in the module.
This changes to a fork that ripped the functionality out.
We made a new type out of go-message/mail.Address without any real reason.
This suddenly made it necessary to convert from one to the other without actually
having any benefit whatsoever.
This commit gets rid of the additional type
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.
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.
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.
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.
If accounts.conf contains an invalid maildir url, return a nice
error instead of panicking.
Log a couple of different error cases to provide extra
information about the error to the user.
Aerc usually used the path []int{1} if it didn't know what the proper path is.
However this only works for multipart messages and breaks if it isn't one.
This patch removes all the hard coding and extracts the necessary helpers to lib.
Provide search and filter with the option to specify more flag based
conditions.
Use '-x <flag>' to search for messages with a flag (seen, answered,
flagged) and '-X <flag>' to search for messages without a flag.
When message dates failed to parse, the error displayed would try to
include the time object it failed to obtain, which would display as
something like 0001-01-01 00:00:00 UTC, which isn't of much help.
Instead, display the text we were trying to parse into a date, which
makes the problem easier to debug.
More mail flags can now be set, unset, and toggled, not just the
read/seen flag.
This functionality is implemented with a new `:flag` and `:unflag`
command, which are extensions to the matching `:read` and `:unread`
commands, adding support for different flags. In fact, the
`read`/`unread` commands are now recognized aliases to `flag`/`unflag`.
The new commands are also well documented in aerc(1).
The change mostly extends the previous read/unread setting functionality
by adding a selection for the flag to change.
