a253e89bda compose: prevent sending empty address list headers
Aerc was sending empty address list header fields (specifically CC by
default). This was causing DKIM failures in lists.sr.ht. RFC 5322 states
that an address field should consist of the field name and one or more
addresses, implying empty fields are not allowed.

57bd9e318b terminal: fix deadlock with finer-grained locking
Commit 1bac87e804 ("terminal: fix race when closing a terminal") fixed
a race in Terminal.Draw by using a mutex. The current locking of the
entire Draw function could create a deadlock, however, since this
function itself might call Terminal.Close which is protected by the same
mutex. A finer-grained locking solves both the race and deadlock
problem.

1bac87e804 terminal: fix race when closing a terminal
Fix race when closing a terminal. The race appears as a nil pointer
dereference panic in pty.StartWithAttrs when trying to access the
provided term.cmd variable.

Before calling pty.StartwithAttrs in the Terminal.Draw function,
term.cmd is checked for nil. Terminal.Close must be called concurrently
right after this check and before/while entering pty.StartWithAttrs.
This can be avoided with a mutex.

4a4050ee0f ui: fix panic in selector when resizing terminal
Fix panic when resizing the terminal by dynamically adjusting the width
of the option selector. The selector does not check the width of the
terminal before printing. This can lead to a panic in the account wizard
when reducing the terminal width.

If the terminal width is not large enough, the space between the options
is reduced. If this is still not enough, then the selector will only
show the focused option and arrows indicating the alternatives.

32a16dcd8d pgp: check encryption keys before sending message
Add check for public keys of all message recipients (to, cc, and bcc)
before sending the message. Adds an OnFocusLost callback to header
editors to facilitate a callback for checking keys whenever a new
recipient is added (OnChange results in too many keyring checks).

Once encryption is initially set, the callbacks are registered. If a
public key is not available for any recipient, encryption is turned off.
However, notably, the callbacks are still registered meaning as s soon
as the user removes the recipients with missing keys, encryption is
turned back on.

57699b1fa6 feat: add gpg integration
This commit adds gpg system integration. This is done through two new
packages: gpgbin, which handles the system calls and parsing; and gpg
which is mostly a copy of emersion/go-pgpmail with modifications to
interface with package gpgbin. gpg includes tests for many cases, and
by it's nature also tests package gpgbin. I separated these in case an
external dependency is ever used for the gpg sys-calls/parsing (IE we
mirror how go-pgpmail+openpgp currently are dependencies)

Two new config options are introduced:
* pgp-provider. If it is not explicitly set to "gpg", aerc will default to
it's internal pgp provider
* pgp-key-id: (Optionally) specify a key by short or long keyId

d3a10b4983 Initialization fix for dynamic folders
There is an issue with backends, that provide dynamic folders, namely
when opening folder, that isn't defined in config file, you get empty
folder. To actually get messages listed, you need to open that folder
twice.

At first attempt only DirectoryInfo is fetched and new
MessageStore created. Second attempt populates previously created
MessageStore with list of messages.

For pre-configured folders, DirectoryInfos are fetched upon connection
to backend and, when folder is opened, MessageStore is updated with list
of messages.

e50ab59284 sort: keep sort criteria applied to folder
Keep the sort criteria applied to the selected folder until the default
sort order should be restored. Call the sort command without arguments
to restore the default sort order.

The current behavior is that the default sort order is restored as soon
as the folder reloads. This happens often and then the results of the
sort command are lost. This makes the sort command not very
user-friendly. Instead, we should keep the sort criteria applied until
the user explicitly wants to restore the default sort order again.

generalize the focusing of header editors - which can now be called by

9f4da4de0c msglist: update message counter upon filter change
Update message counter in msglist when the filter is changed (either set or

When we apply a filter, we change the number of uids in the message
store. This can unintentionally trigger the storeUpdate() function of
the msglist which checks the number of uids for new messages and
advances the pointer by the difference in the number of messages. This
can be avoided when we update the message counter upon changing the
filter.

74366d895d viewer: add key passthrough mode

'/', to easily enter "less" search mode. When in the passthrough mode,
all bindings are ignored by default. The default binds.conf only defines
a single keybinding in that mode: <Esc> to get back out. $ex is bound to
<C-x> to allow typing colons.

cb3090956c dirlist: skip unnecessary change-folder action
when traversing the directory list, aerc will fetch the contents for
every directory even though the user might just move on to the next.
This causes an unnecessary delay (and load on the worker) and can be
avoided by skipping the old change-folder action when a newer one
arrives within a predefined time interval.

eafb537081 dirlist: improve change-folder responsiveness
improves change-folder responsiveness. When changing folders, the
highlighted directory is currently updated in a callback function to the
open-directory action. This creates an unpleasent lag in the ui until
the entire operation is done. Instead, we should provide an immediate
visual feedback of the selection to the user and keep loading the
directory contents in the background.

7f34cab5e5 terminal: fix nil pointer dereference in pty.Getsize
pty.Getsize() is used in the Draw function of the terminal widget and wraps the
pty.GetsizeFull() function. However, pty.Getsize does not check the returned
error from pty.GetsizeFull before dereferencing the winsize struct. In case of
an error, this will cause a nil pointer deference and panic.

This has been reported in the upstream package, but in the meantime, we can
directly use pty.GetsizeFull.

b19b844a63 pgp: PGP/MIME encryption for outgoing emails
implements PGP/MIME encryption with go-pgpmail. The Encrypt() function of
go-pgpmail requires a list of public keys which are taken from the
keystore. The keystore is searched for the email addresses of all
recipients (to, cc, and bcc).
If you want to be able to read the encrypted email afterwards, add
yourself as a recipient in either to, cc, or bcc as well.

Public keys can be exported from gpg into aerc as follows:
$ gpg --export  >> ~/.local/share/aerc/keyring.asc

When composing a message, the encryption is enabled with the
":encrypt" command. This sets a bool flag in the Composer struct.
A reapted application of this command will toggle the flag.
The encrypted message can also be signed by using the ":sign"
command before or after ":encrypt".

A message is signed with the ":sign" command. The sign command sets
a bool flag in the Composer struct. Using the command repeatedly will

175d0efeb2 binds: add account specific bindings
When using aerc for multiple accounts often bindings might differ
slightly between accounts. For example:

* Account A archives to one directory (:archive)
* Account B archives to monthly directories (:archive month)

Add account specific bindings to allow the user to add a "context" to a
binding group using a context specifier and a regular expression.

Currently the only context specifier is 'account'.

The regular expression is validated against the accounts loaded from
accounts.conf and the configuration fails to load if there are no
matches.

Contextual bindings are merged with global bindings, with contextual
bindings taking precedence, when that context is active.

Bindings are be configured using a generic pattern of
'view:context=regexp'. E.g.:

    # Globally Applicable Archiving
    [messages]
    A = :read<Enter>:archive<Enter>

    # Monthly Archiving for 'Mailbox' Account
    [messages:account=Mailbox$]
    A = :read<Enter>:archive month<Enter>

In the above example all accounts matching the regular expression will
archive in the monthly format - all others will use the global binding.

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.

98d778eeae widgets/terminal: Only call vterm.ScreenCell.Attrs once in styleFromCell
This fixes a substantial performance issue when scrolling emails with
long/complicated contents, where scrolling down a single line can take
something like hundreds of ms before the screen is updated to reflect
the scroll. It's really bad if the email has lots of columns, e.g. like
if it's an html email that was passed through a filter (w3m, etc) to
render it.

Using pprof, I found that the multiple calls to vterm.ScreenCell.Attrs()
in styleFromCell were really really expensive. This patch replaces them
with a single call.

Here's a before and after with a simple, but very manual test of opening
a large email with contents that went through a w3m filter and
continuously scrolling up and down over and over for ~30 seconds:

f9bba3d17d Apply relevant msglist styles in order
Allow styles to be layered over a base style. The list of styles to
apply is layered over the base style in order, such that if the layer
does not differ from the base it is not used. The order that these
styles are applied in is, from first to last:

msglist_default
msglist_unread
msglist_read    (exclusive with unread, so technically the same level)
msglist_flagged
msglist_deleted
msglist_marked

So, msglist_marked style dominates.

This fixes an issue where the msglist_deleted style was not being applied.

fe42beb3e4 dirlist: fix empty row if dir is added
There is a window where a new dir entry isn't yet in the dirlist.dir.
dirlist.ensureScroll however expected to always find a valid index.
Add a check so that we don't try to scroll to a -1 index.

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.

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.

2d7a870725 show error if account view creation fails
This can happen for example if aerc is compiled without notmuch support but the
notmuch worker is requested.
Pushing a status message isn't good enough, as this gets overridden pretty
quickly if one has multiple accounts configured.
So we show a fullscreen error instead.
