* config: make various sections accessible via global varsRobin Jarry2022-12-141-2/+3
| | | | | | | | | | | | | | | | | | | | There is only one instance of AercConfig which is associated to the Aerc widget. Everywhere we need to access configuration options, we need somehow to get a reference either to the Aerc widget or to a pointer to the AercConfig instance. This makes the code cluttered. Remove the AercConfig structure and every place where it is referenced. Instead, declare global variables for every configuration section and access them directly from the `config` module. Since bindings and ui sections can be "contextual" (i.e. per account, per folder or per subject), leave most local references intact. Replacing them with config.{Ui,Binds}.For{Account,Folder,Subject} would make this patch even more unreadable. This is something that may be addressed in the future.

| | | | | | | | | | | Change the default provider to gpg unless the internal keyring is initialized and contains one key. This should be more user friendly.

* logging: homogenize levelsRobin Jarry2022-12-022-2/+2
| | | | | | | | | | | | | | | | | | The main goal is to ensure that by default, the log file (if configured) does not grow out of proportions. Most of the logging messages in aerc are actually for debugging and/or trace purposes. Define clear rules for logging levels. Enforce these rules everywhere. After this patch, here is what the log file looks like after starting up with a single account: INFO 2022/11/24 20:26:16.147164 aerc.go:176: Starting up version 0.13.0-100-g683981479c60 (go1.18.7 amd64 linux) INFO 2022/11/24 20:26:17.546448 account.go:254: [work] connected.

* pgp: enable quoted replies of encrypted messagesTim Culverhouse2022-08-311-0/+15
| | | | | | | | | | | | | | When quoting an encrypted message for reply, the quoted text is shown as "Version: 1.0". This is due to this being the first non-multipart text portion of the message, which is what the quoted reply logic looks for. Properly quote replies to encrypted messages by decrypting the message, and quoting the content. The message must be open in a message view in order to quote it (it must be decrypted, which is handled by the message viewer).

* gpg: fix error handling during decryptionTim Culverhouse2022-06-281-3/+5
| | | | | | | | | | | | An non-zero exit code from the execution of gpg during decryption would prevent aerc from parsing the output of gpg. The output should always be parsed. Gpg can exit with an error due to not being able to validate a signature. Aerc handles this error with the UI, and therefore all output should be parsed regardless of exit state of gpg. The parsing of stdout will find the errors and report back to aerc properly. Signed-off-by: Tim Culverhouse <tim@timculverhouse.com> Acked-by: Moritz Poldrack <moritz@poldrack.dev>

* 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 Culverhouse2022-05-064-0/+23
| | | | | | | | | | | | | | | | 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.

* 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>
