* seqmap: refactor seqmap to use slice instead of mapTim Culverhouse2022-08-035-48/+80
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The imap worker's seqmap is represented as a map of sequence number to UID. This presents a problem when expunging group of messages from the mailbox: each individual expunge decrements the sequence numbers by 1 (for every sequence number greater than the expunged). This requires a looping around the map to update the keys. The use of a map also requires that both the sequence number and the UID of a message be known in order to insert it into the map. This is only discovered by fetching individual message body parts (flags, headers, etc), leaving the seqmap to be empty until we have fetched information about each message. In certain instances (if a mailbox has recently been loaded), all information is loaded in memory and no new information is fetched - leaving the seqmap empty and the UI out of sync with the worker. Refactor the seqmap as a slice, so that any expunge automatically decrements the rest of the sequences. Use the results of FetchDirectoryContents or FetchDirectoryThreaded to initialize the seqmap with all discovered UIDs. Sort the UIDs in ascending order: IMAP specification requires that sequence numbers start at 1 increase in order of ascending UID. Add individual messages to the map if they come via a MessageUpdate and have a sequence number larger than our slice. Update seqmap tests with new logic.

Make sure to pad the patch number with zero characters to allow series of up to 999 patches. Only re-order messages before piping them if all the Message-Id headers look like git-send-email headers.

| | | | | | | | | | | | | | | | Set the SkipSort flag when sending directory infos for counting purposes.

| | | | | | | | | | | | | | | | | | This can be useful in cases when: 1. outgoing-cred-cmd requires a user action or confirmation (e.g. when using pass with a Yubikey or similar smart card that requires a user to enter a pin or touch the device when decrypting the password) 2. A user starts aerc frequently, but not all the sessions end up with sending emails 3. So the user only wants to execute outgoing-cred-cmd when the password is really used, so the user doesn't have to enter pin or touch their Yubikey each time aerc starts Signed-off-by: Stas Rudakou <stas@garage22.net> Acked-by: Robin Jarry <robin@jarry.cc>

| | | | | | | | | | | | | | This is a workaround for https://todo.sr.ht/~rjarry/aerc/22, by injecting zero-width spaces in front of wide characters to make up width calculation in fmt.Sprintf. With this applied, columns will still be misaligned a little only if they are left with trailing zero-width spaces when cut. It is better than a large offset caused by each wide characters in the column.

| | | | | | | | | | | | | | | | Debounce client-side thread building in the message store. Debouncing is useful when multiple messages are loaded, i.e. when scrolling with PgUp/PgDown. Without the debouncing, all client-side threads will be built everytime the message store is updated which creates a noticable lag in the message list ui when client-side threading is activated. The default debouncing delay can be changed by changing 'client-threads-delay' in the UI config section. Signed-off-by: Koni Marti <koni.marti@gmail.com> Acked-by: Robin Jarry <robin@jarry.cc>
