command, or for imap with the STATUS command, at start or on
reconnection and every X time duration
IMAP:
The selected folder is skipped, per specification. Additional config
options are included for including/excluding folders explicitly.
Maildir/Notmuch:
An external command will be run in the background to check for new mail.
An optional timeout can be used with maildir/notmuch. Default is 10s
New account options:
check-mail
check-mail-cmd (maildir/notmuch only)
check-mail-timeout (maildir/notmuch only), default 10s
check-mail-include (IMAP only)
check-mail-exclude (IMAP only)
If unset, or set less than or equal to 0, check-mail will be ignored

Add a debouncer to the idle mode. Avoid unnecessary idling when another
job arrives within a certain time frame.
For example, the ui sends three messages to the worker at the same time
when we open a message (FlagMessage, FetchMessageBodyPart, and the
FetchMessageHeaders). The debouncer prevents the unnecessary entering
and leaving of the idle mode between those messages.

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.

Wait is capped at 16s. Prevents many reconnect attemps in a short time period.

improved the reliability of the reconnect mechanism but did not
implement controls to prevent the triggering of too many reconnects

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.

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.

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.
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.
- Add maildir flags to complement a messages imap flags
- Set the "seen" flag on sent messages when using the maildir backend
- Cleanup AppendMessage interface to use models.Flag for both IMAP and
maildir
Apparently sending an event for every incoming messageInfo slows down
the application significantly.
Therefore this slows down the emmision rate, on the cost of being out of date
in some cases.
The idle restart code is at the end of handleMessage in the worker.
However if an unsupported msg comes in, we returned early, skipping the re-init.
That lead to a crash due to double closing idleStop in the next iteration.
Configure an oauthbearer source without a token_endpoint
parameter would panic due to nil pointer dereference
Example
source=imaps+oauthbearer://frode.aa%40gmail.com@imap.gmail.com:993
source-cred-cmd=pass oatuh2 frode.aa@gmail.com
token_endpoint is not required as it will use the provided
password as access_token when it is not set
This fixes ~sircmpwn/aerc2#245. This sets up the imap client to send
error messages to the logger of the worker. Errors now end up in the
bottom status line.
https://todo.sr.ht/~sircmpwn/aerc2/245
imaps+oauthbearer://user:token@host?token_endpoint=...
- the config Source password is used as access token if
no token_endpoint parameter is set
- the config Source password is used as refresh token if
token_endpoint parameter is set, and used to exchange
with an access token
The implementation has only been tested with Gmail.

Before, we were using several IMAP-specific concepts to represent
information being displayed in the UI. Factor these structures out of
the IMAP package to make it easier for other backends to provide the
required information.
Before, the information needed to display different parts of the UI was
tightly coupled to the specific messages being sent back and forth to
the backend worker. Separating out a models package allows us to be more
specific about exactly what a backend is able to and required to
provide for the UI.
Adds an archive command that moves the current message into the folder
specified in the account config entry.
Supports three layouts at this point:
- flat: puts all messages next to each other
- year: creates a folder per year
- month: same as above, plus folders per month
This also adds a "-p" argument to "cp" and "mv" that works like
"--parents" on mkdir(1). We use this to auto-create the directories
for the archive layout.
