Improvements to Drafts folder cleaning functionality

Send Later compacts the user's Drafts folder in certain circumstances, but in reality for IMAP Drafts folders it's probably sufficient to just expunge the IMAP folder without compacting the local copy of it. Therefore, before compacting we now attempt expunging and only compact if the expunge fails. This should further minimize the Drafts folder corruption issues we've been seeing.

Another attempted corruption fix; make menu commands work for >100 messages

Increase the amount of time that Send Later requires the Drafts folder to be idle for before attempting to compact it from 1 second to 5 seconds, in yet another attempt to work around the Thunderbird Drafts folder corruption issue.

Fix a bug which was causing only 100 messages to be processed by the Send Later menu commands if more than that were selected.

Reattach the scheduling popup; another attempt to fix Drafts corruption

Reattach scheduling popup for TB128+

The scheduling popup that appears when you type Ctrl-Shift-Enter or Click the "Send Later" button in a compose window is supposed to be "attached" to the button, and things work better overall when it is. Unfortunately, there is/was a bug in Thunderbird 115 which would sometimes make the attached window disappear immediately after appearing, so as a workaround we disconnected the popup from the button [details]. We've been asked by the Thunderbird team whether this is still an issue in Thunderbird 128, so I'm re-attaching the popup to the window for TB128 and newer. However, there is a new preference you can uncheck in the preferences window if you run into problems with this and need to go back to a detached popup.

Another attempt to fix the Drafts folder corruption issue

In rare cases, Thunderbird is corrupting the local copy of the user's Drafts folder when a message is scheduled with Send Later [details]. To be clear, this is a Thunderbird bug, not a Send Later bug, but something Send Later is doing is triggering it. In previous releases I've tried various workarounds, but none of them have worked reliably. This release contains yet aanother attempted workaround approach: monitoring the timestamps on the local Drafts folder data files and not compacting the folder until they have been unmodified for a full second.

Another attempt to fix drafts corruption; close pop-up window when compose window closes

This release attempts a different approach to fixing the corrupt drafts folder problem that some users are experiencing. Rather than compacting the drafts folder shortly after a message is scheduled, we wait until the beginning of the next main loop run to do it. Relatedly, this release fixes a bug which was causing drafts folders to be compacted repeatedly when they didn't need to be.

Also, this release fixes the problem of the pop-up window not getting dismissed properly after a message is scheduled. As a bonus, it also makes the pop-up window go away automatically if the user closes the compose window while the pop-up window is open.

Fix for scheduling from message list; another attempt at fixing drafts folder corruption

When the user selects one or more messages in the messages list and then uses the "Schedule message(s)" menu command, fill in the pop-up window properly with the default send time.

Increase the compact delay after scheduling, intended to avoid Drafts folder corruption, from 1 second to 2 seconds, because apparently 1 second isn't long enough. I don't know for certain that this change will work but I need to get it out into the world to collect more data about it.

Fix rare data corruption issue with TB128

In rare cases we can't quite identify, scheduled drafts are getting corrupted when they are saved by Send Later. This appears to be a race condition related to the fact that we compact the Drafts folder immediately after saving a draft. As a workaround, which seems to work, for the time being we are delaying the compact for a second after saving the draft.
