* ui: update vaxis to v0.8.5Tim Culverhouse2024-04-021-2/+2
| | | | | | | | | | | | | Update vaxis library to v0.8.5 which includes several terminal widget fixes: - Tab stop positions were off by 1 - Now reponds to secondary DA queries - Fix encoding of function keys higher than F12 Signed-off-by: Tim Culverhouse <tim@timculverhouse.com> Tested-by: Inwit <inwit@sindominio.net> Acked-by: Robin Jarry <robin@jarry.cc>
* mod: update all dependenciesRobin Jarry2024-04-021-58/+74
| | | | | | | | | | | | | | | | | | Patch produced with the following commands: go mod edit -dropreplace=golang.org/x/crypto go get -t -u go mod tidy I dropped the replace of x/crypto. The only use for the fork from ProtonMail is for openpgp which has been deprecated by the official implementation. And aerc explicitly uses the correct import path where needed. go-smtp update was a bit harsh. The API was changed completely.

* ui: update vaxis and only use disambiguate csi-u flagTim Culverhouse2024-02-261-2/+2
| | | | | | | | | | | | | | | | | | Update vaxis to 0.8.2, which adds the ability to specify any CSI-u flag combination. Explicitly only use the disambiguate flag. This enables aerc to have additional keybinds not previously possible (C-i, C-m) while preventing some internal logic bugs relating to single-modifier key presses. While these events can be useful, they are not needed in aerc and aerc currently would need several workarounds to properly handle them so let's just not request them in the first place.

* jmap: set explicit sender and recipientsKarel Balej2024-02-121-2/+2
| | | | | | | | | | | | | | | JMAP is able to automatically determine sender and recipients based on the message headers after it is submitted for sending. However this means that it is not possible to send a message with the From header not matching the account with this approach (or to send the message to recipients not listed in the headers). Luckily, JMAP allows setting the envelope containing the envelope sender and recipients manually. Modify the code to do so. Also bump go-jmap to include a fix needed for this to work.

| | | | | | | | | | | | | | | | | | | | | | | | | | Define a SearchCriteria structure. Update the FetchDirectoryContents, FetchDirectoryThreaded and SearchDirectory worker messages to include this SearchCriteria structure instead of a []string slice. Parse the search arguments in a single place into a SearchCriteria structure and use it to search/filter via the message store. Update all workers to use that new API. Clarify the man page indicating that notmuch supports searching with aerc's syntax and also with notmuch specific syntax. getopt is no longer needed, remove it from go.mod. NB: to support more complex search filters in JMAP, we need to use an email.Filter interface. Since GOB does not support encoding/decoding interfaces, store the raw SearchCriteria and []SortCriterion values in the cached FolderContents. Translate them to JMAP API objects when sending an email.Query request to the server.

* commands: pass raw command line down to template evaluationRobin Jarry2023-10-281-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | Some commands need to invoke others and/or run shell commands. For this, we need the raw command line as entered by the user. Pass it down the call chain just before it is split to invoke the command Execute method. Remove unit tests for the template expand() test which does have any added value now that it is performed on a single string without any quote juggling. Update all code to handle a single string instead of a list of arguments. Introduce a new dependency on git.sr.ht/~rjarry/go-opt to deal with shell splitting. This is in preparation for using opt.ArgsToStruct to parse arguments for all aerc commands. There should be no functional change after this patch.

| | | | | | | | | | | | The mbox worker uses the only reference to the datacounter object (see previous commit where it was removed from 'postpone'). The counter object in mbox is counting the size of the mbox message. Use io.Discard and the result from the io.Copy call to set this size. This saves us from writing to memory, since io.Discard will not store any of the written bytes. It also removes the dependency on datacounter.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for JMAP backends. This is on par with IMAP features with some additions specific to JMAP: * tagging * sending emails This makes use of git.sr.ht/~rockorager/go-jmap for the low level interaction with the JMAP server. The transport is JSON over HTTPS. For now, only oauthbearer with token is supported. If this proves useful, we may need to file for an official three-legged oauth support at JMAP providers. I have tested most features and this seems to be reliable. There are some quirks with the use-labels option. Especially when moving and deleting messages from the "All mail" virtual folder (see aerc-jmap(5)). Overall, the user experience is nice and there are a lot less background updates issues than with IMAP (damn IDLE mode hanging after restoring from sleep). I know that not everyone has access to a JMAP provider. For those interested, there are at least these two commercial offerings: https://www.fastmail.com/ https://www.topicbox.com/ And, if you host your own mail, you can use a JMAP capable server: https://stalw.art/jmap/ https://www.cyrusimap.org/imap/download/installation/http/jmap.html Link: https://www.rfc-editor.org/rfc/rfc8620.html Link: https://www.rfc-editor.org/rfc/rfc8621.html Signed-off-by: Robin Jarry <robin@jarry.cc> Tested-by: Tim Culverhouse <tim@timculverhouse.com>

| | | | | | | | | | | | | | | | | | | | | | | | | Implement an mbox backend worker. Worker can be used for testing and development by mocking a backend for the message store. Worker does not modify the actual mbox file on disk; all operations are performed in memory. To use the mbox backend, create an mbox account in the accounts.conf where the source uses the "mbox://" scheme, such as source = mbox://~/mbox/ or source = mbox://~/mbox/file.mbox If the mbox source points to a directory, all files in this directory with the .mbox suffix will be opened as folders. If an outgoing smtp server is defined for the mbox account, replies can be sent to emails that are stored in the mbox file.

* imap: add option to cache headersTim Culverhouse2022-06-221-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add option to cache headers for imap accounts. Cache db is located at $XDG_CACHE_DIR/aerc/{account name}. The cache is cleaned of stale entries when aerc is first opened. Two new account level configuration options are introduced: * cache-headers (Default: false) * cache-max-age (Default: 30 days (720 hours)) The change in worker/imap/open.go is to set the selected directory. This is required to access the UIDVALIDITY field, which is used in combination with the message ID to form the key for use in the cache db. The key structure is: "header.{UIDVALIDITY}.{UID}" Where reasonable, cache does not stop aerc from running. In general, if there is an error in the cache, aerc should continue working as usual. Errors are either displayed to the user or logged. All messages are stored without flags, and when retrieved have the flags set to SEEN. This is to prevent UI flashes. A new method to FetchMessageFlags is introduced to update flags of cached headers. This is done asynchronously, and the user will see their messages appear and then any flags updated. The message will initially show as SEEN, but will update to unread. I considered updating the cache with the last-known flag state, however it seems prudent to spare the R/W cycle and assume that - eventually - all messages will end up read, and if it isn't the update will occur rather quickly. Note that leveldb puts a lock on the database, preventing multiple instances of aerc from accessing the cache at the same time. Much of this work is based on previous efforts by Vladimír Magyar.

* msgviewer: parse and display authentication resultsKoni Marti2022-06-091-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Parse the Authentication-Results header and display it in the message viewer (not enabled by default). DKIM, SPF and DMARC authentication methods are supported. Implement recommendation from RFC 7601 Sec 7.1 to have an explicit list of trustworthy hostnames before displaying the authentication results. Be aware that the authentication headers can be forged. To display the results for a specific authentication method, add the corresponding name to the layout of headers in the viewer section of aerc.conf, e.g. to display all three, use: header-layout = From|To,Cc|Bcc,Date,Subject,DKIM|SPF|DMARC More information will be displayed when "+" is appended to the authentication method name, e.g. DKIM+ or SPF+ or DMARC+. Also, add the trustworthy hosts per account with the trusted-authres parameter, e.g. trusted-authres = * to trust every host or use regular expressions for a finer control. Multiple hosts can be entered as a comma-separated list. Authentication results will only be displayed when the host is listed in the trusted-authres list.
