* maildir: enable backend threadsTim Culverhouse2022-11-091-1/+85
| | | | | | | | | | Add thread capability to maildir backend. Enables the maildir worker to thread the entire folder, as opposed to only the displayed messages via client side threads.

* maildir: speedup move to larger foldersBence Ferdinandy2022-11-091-7/+4
| | | | | | | | | | When moving or archiving to a very large folder, aerc requests directory info, which can takes several seconds to receive. Also, when moving, we post a MessagesDeleted message. Remove unnecessary call to directory info and change posted message to the correct MessagesMoved.

| | | | | | | | | | | Prepare attachments for multiple reads. The data for lib.PartAttachment is stored as an io.Reader which can only be read once. This will cause an issue when we want to call composer.WriteMessage multiple times, i.e. for a message preview.

* ui: invalidate ui when queuing redrawTim Culverhouse2022-11-064-5/+3
| | | | | | | | | | | | | | | The QueueRedraw function should always be preceeded by a call to ui.Invalidate in order to make a redraw a occur. In one instance, this was not done and it was possible for the UI to not redraw itself (when a terminal closes, a UI redraw request is made but it is possible for the UI to not be invalidated as a result of the close). Move the call to Invalidate into the QueueRedraw function to ensure that every QueueRedraw call will redraw the screen.

* maildir: keep less data in memory for sortingTim Culverhouse2022-11-063-1/+67
| | | | | | | | | | | | | | | | Sorting opens and reads portions of every file within a directory in order to gather the data needed. Specifically, RFC822Headers and BodyStructure are not needed. The RFC822Headers field stores a lot of information, and the BodyStructure field requires parsing the body of the email. Don't set these two values when parsing. Note: in my testing, this dropped sorting a 52k archive from 2.2gb of ram usage, to < 500mb Signed-off-by: Tim Culverhouse <tim@timculverhouse.com> Acked-by: Robin Jarry <robin@jarry.cc>

* maildir: set SkipSort when checking mailTim Culverhouse2022-11-061-1/+2
| | | | | | | | | | | | | The maildir worker's check-mail command did not include the SkipSort directive in the DirectoryInfo, which would cause a fresh fetching of directory contents on the selected maiboxes.

"sort-thread-siblings" is false by default and the siblings will be sorted based on their uid number. Note that this options will only work with client-side threading and when the backend supports sorting. Also, it comes with a slight performance penalty.

| | | | | | | | | | | | | | Instead of failing completely when address-book-cmd returns an invalid line, ignore the line and report a warning in the logs. Do not wait for 100 "valid" addresses before bailing out as the command could only output garbage in large quantities. The issue of the command not printing any new line characters still exists. We could address this but I think it would be overkill.

* address-book-cmd: ignore completion above 100 itemsRobin Jarry2022-11-021-0/+17
| | | | | | | | | | | | | | | | | Avoid aerc from consuming all memory on the system if an address book command returns 12 million addresses. Read at most the first 100 lines and kill the command if it has not finished. Display a warning in the logs for good measure. The command is now assigned an different PGID (equal to its PID) to allow killing it *and* all of its children. When the address book command is a shell script that forks a process which never exits, it will avoid killing the shell process and leaving its children without parents.

* notmuch: move new maildir files to cur upon opening a folderJulian Pidancet2022-10-271-1/+39
| | | | | | | | | | | | | | | | | | | | | By default "notmuch new" will index files in place and won't move new files from the new/ directory to cur/ because it assumes that is the job of the email client. During normal operation, once moved by the client, the "notmuch new" command will "fix" the database by detecting file renames. This workflow is a problem because we need to move the new/ files to cur/, otherwise the maildir lib will not work properly, but at the same time we cannot afford the notmuch database to be out of sync with the location of message files on disk, because we rely on it for listing folders, displaying emails, ect... This change uses a trick that request notmuch to synchronize message tags to maildir flags, that will effectively rename new files and cause them to be moved into the cur/ directory.

| | | | | | | | | | | | | | | | | | | | | | | | | | | By associating the notmuch database with a maildir store, we can add the Copy/Move/Delete operations on messages to the notmuch backend. This change assumes that the notmuch database location is also the root of the maildir store. In a previous change, we added the ability to dynamically add and remove message files to the notmuch DB. This change uses this facility to synchronize the database with the filesystem operations on maildir files. While it's still possible to use the query-map file to create virtual folders from notmuch search queries, the sidebar is now loaded with the folders found in the maildir store. With notmuch, two identical but distinct message files can be indexed in the database with the same key.
