commit 0ea1fe6c35991b6650a3530ac6cbfe6e36f6133d
Author: Michael James Gratton <mike vee net>
Date: Fri Mar 9 12:14:15 2018 +1100
Don't use the database for internal ConversationMonitor bookkeeping.
This replaces the use of Geary.Folder.find_boundaries_async in
ConversationMonitor with a simple sorted set of known in-folder message
ids. This is both easy and fast, reduces needless DB load when loading
conversations, and also allows allows removing what is otherwise
single-use implementation overhead in classes deriving from Folder.
* src/engine/app/app-conversation-monitor.vala (ConversationMonitor):
Replace get_lowest_email_id_async() with window_lowest property, update
call sites. Implement the property by using a sorted set of known
listed email ids from the base folder. Update the set as messages in
the base folder are listed. Rename notify_emails_removed to just
removed and remove ids from the set if any messages from the base
folder are removed.
* src/engine/api/geary-folder.vala (Folder): Remove
get_lowest_email_id_async since it is now unused, do same for all
subclasses.
