Koni Marti 132b5fed9e mbox: filtering for mbox accounts
Use FetchDirectoryContents for filtering instead of the SearchDirectory
message. This was an omission from rebasing the mbox worker and from not
realizing that c2f4404f ("threading: enable filtering of server-side
threads") changed the way we filter in the message store for the
server-side threading implementation. This patch enables filtering for
the mbox worker.

Tim Culverhouse fdfec2c07a seqmap: refactor seqmap to use slice instead of map
The imap worker's seqmap is represented as a map of sequence number to
UID. This presents a problem when expunging group of messages from the
mailbox: each individual expunge decrements the sequence numbers by 1
(for every sequence number greater than the expunged). This requires a
looping around the map to update the keys. The use of a map also
requires that both the sequence number and the UID of a message be known
in order to insert it into the map. This is only discovered by fetching
individual message body parts (flags, headers, etc), leaving the seqmap
to be empty until we have fetched information about each message. In
certain instances (if a mailbox has recently been loaded), all
information is loaded in memory and no new information is fetched -
leaving the seqmap empty and the UI out of sync with the worker.

Refactor the seqmap as a slice, so that any expunge automatically
decrements the rest of the sequences.

Use the results of FetchDirectoryContents or FetchDirectoryThreaded to
initialize the seqmap with all discovered UIDs. Sort the UIDs in
ascending order: IMAP specification requires that sequence numbers start
at 1 increase in order of ascending UID.

Add individual messages to the map if they come via a MessageUpdate and
have a sequence number larger than our slice.

Update seqmap tests with new logic.

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

Robin Jarry 5dec1f09b1 imap: fix error when server returns a message without body section
When opening unread emails from certain people (I won't name any names,
sorry), an annoying error message is displayed on the status line:

 could not get section &imap.BodySectionName{BodyPartName:
 imap.BodyPartName{Specifier:"", Path:[]int(nil), Fields:[]string(nil),
 NotFields:false}, Peek:false, Partial:[]int(nil), value}

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
to get rid of these extra messages.

Koni Marti a1a276e002 mbox: implement an mbox backend worker
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.

Tim Culverhouse 7aa71d334b imap: add option to cache headers
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.

Much of this work is based on previous efforts by Vladimír Magyar.

When moving/copying/deleting/archiving a message in imap, the RUE counts
displayed in the dirlist would not update properly. Maildir has (had) an
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
that the action has happened.

Robin Jarry 8ed95b0d2a imap: avoid crash when replying to unread message
When running `:reply -q` on an unread message, aerc crashes after
opening the editor:

panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x18 pc=0x5d1019]

goroutine 63 [running]:

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
to get rid of these extra messages.

Koni Marti 698c0957d7 pgp: ensure CRLF line endings in pgpmail reader
Ensure CRLF line endings in the pgpmail reader. Fix the pgp signature
verification for maildir and notmuch.

These backends do not return the full message body with CRLF
line endings. But the accepted OpenPGP convention is for signed data to
end with a <CR><LF> sequence (see RFC3156).

If this is not the case the signed and transmitted data are considered
not the same and thus signature verification fails.

Moritz Poldrack ae83373fa6 logging: added a log on panic
Since panics still regularly "destroy" the terminal, it is hard to get a
stack trace for panics you do not anticipate. This commit adds a panic
handler that automatically creates a logfile inside the current working
directory.

It has to be added to every goroutine that is started and will repair
the terminal on a panic.

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.
