2022-05-04pgp: check for signing key before signing timeTim Culverhouse
Check that the signing key exists when the user issues the :sign command. The signing key ID will be displayed in the security status also, allowing the user to see what key will be used to sign the message.

2022-04-27feat: add gpg integrationTim Culverhouse
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 Signed-off-by: Tim Culverhouse <tim@timculverhouse.com> Acked-by: Koni Marti <koni.marti@gmail.com> Acked-by: Robin Jarry <robin@jarry.cc>

2022-04-14Initialization fix for dynamic foldersAivars Vaivods
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.

2022-03-25sort: keep sort criteria applied to folderKoni Marti
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.

2022-03-24logging: fix race condition in startupMoritz Poldrack
If a panic occurs in one of the workers, it can happen after the UI was initialised, but before the cleanup function has been registered. With this the start of the worker loops is deferred until the cleanup routine was registered. Signed-off-by: Moritz Poldrack <git@moritz.sh>
2022-03-23logging: added a log on panicMoritz Poldrack
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. Signed-off-by: Moritz Poldrack <git@moritz.sh> Acked-by: Robin Jarry <robin@jarry.cc>

2022-03-22compose: make headerEditor focusing more reliableTim Culverhouse
Focusing header editors was hardcoded as integers which only worked with the default ui. If a user changed the UI to, for example, put CC as a field below "to", FocusSubject would focus the CC field instead of the subject. This commit reuses and modifies the function FocusEditor to generalize the focusing of header editors - which can now be called by name via FocusEditor(name string) Signed-off-by: Tim Culverhouse <tim@timculverhouse.com> Acked-by: Robin Jarry <robin@jarry.cc>
2022-03-20msglist: update message counter upon filter changeKoni Marti
Update message counter in msglist when the filter is changed (either set or cleared in the msgstore). 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.

2022-03-14viewer: add key passthrough modekt programs
When trying to search in less, keys bound to viewer functions can't be used as part of the search query, which makes the search useless. Add a view::passthrough binding mode and a :toggle-key-passthrough command go toggle in and out of that mode. By default, typing '/' in the viewer is bound to enabling key passthrough and automatically inserting '/', 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.

2022-02-25aerc: always check SelectedAccount return valueRobin Jarry
aerc.SelectedAccount() is used in lots of places. Most of them without checking the return value. In some cases, the currently selected tab is not related to any account (widget.Terminal for example). This can lead to unexpected crashes when accessing account specific configuration. When possible, return an error when no account is currently selected. If no error can be returned, fallback to non-account specific configuration.

2022-02-24threading: implement on-the-fly message threadingKoni Marti
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.

2022-02-06imap: improve reconnect stabilityKoni Marti
improves the robustness of the imap reconnect feature which was introduced in commit beae17a6da37 ("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.

2022-01-24dirlist: skip unnecessary change-folder actionKoni Marti
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.

2022-01-24dirlist: improve change-folder responsivenessKoni Marti
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. Signed-off-by: Koni Marti <koni.marti@gmail.com>
2022-01-19terminal: fix nil pointer dereference in pty.GetsizeKoni Marti
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.

2022-01-07pgp: PGP/MIME encryption for outgoing emailsKoni Marti
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". References: https://todo.sr.ht/~rjarry/aerc/6 Signed-off-by: Koni Marti <koni.marti@gmail.com>
2022-01-07pgp: PGP/MIME signing for outgoing emailsKoni Marti

Private keys can be exported from gpg into aerc as follows: $ gpg --export-secret-keys >> ~/.local/share/aerc/keyring.asc A message is signed with the ":sign" command. The sign command sets a bool flag in the Composer struct. Using the command repeatedly will toggle the flag.
