* store: clean marked messagesKoni Marti2022-05-311-0/+18
| | | | | | | | | | | | | Clean marked messages after new uids are fetched. Commit 5c5158b3 ("store: remove callbacks on error") removed side effects in the message store after a longer suspend period but neglected to remove marked zombie messages.

* gpg: refactor tests for macos compatibilityTim Culverhouse2022-05-253-186/+156
| | | | | | | | | | | | | | Refactor lib/crypto/gpg tests to facilitate unit test runs on macos. Macos creates temporary directories with names too long to call gpg-agent (108 characters). Additionally, too many concurrent test calls created IPC errors to gpg-agent. To get around this, tests were given shorter names and refactored into subtests to create fewer concurrent tests Tested on Linux and MacOS.

* pgp: check encryption keys before sending messageTim Culverhouse2022-05-065-0/+37
| | | | | | | | | | | | | | | | 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.

* store: remove callbacks on errorKoni Marti2022-05-061-3/+28
| | | | | | | | | | | | | | | | | | | | | Unmark deleted messages and remove pending headers in the callback function when an error in the backend occurs (e.g. due to connection issues). The message store marks messages that should be deleted. If the delete operation in the backend fails, messages are never unmarked and will remain rendered as empty lines in the message list. This also affects the move and archive commands that rely on a copy and delete operation. A similar issue occurs with the pending headers when the operation to fetch them fails. In this case, messages will appear as loading indefinitely in the message list and are never re-fetched because the corresponding pending headers from the failed operations are still present.

* feat: add gpg integrationTim Culverhouse2022-04-2714-21/+1461
| | | | | | | | | | | | | | | | | | | 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>

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.

* imap: fix no-envelope-for-message errorKoni Marti2022-04-111-1/+3
| | | | | | | | | | | | | | | | | | | | | Fix the "no envelope available for this message" error that can occur when using the same imap mailbox in another mailclient (e.g. through a webmail interface) at the same time. Complements the fixes in commit 7fe7fe4 ("ui: fix panic in header formatter") and commit 074b0a1 ("view,list: fix crash when viewing incomplete imap messages"). The error is caused when a message attribute update is received by the message store before the message list had a chance to fetch the proper header first. In this case, an (incomplete) message info is stored in the message store and the message list will never fetch the correct header. To prevent this, add only messages to the store with a non-nil envelope but make sure that message attribute updates are properly merged.

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.

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.
