This requires another database schema change. With this change messages
at the root of a thread reference themselves in the 'threads' table,
i.e. 'root' contains the value of 'id' for these messages. It makes
selecting all messages in a thread much simpler.
Database updates can be surprisingly slow. This lead to slow updates of
the user interface which in turn made working with K-9 Mail not as fun
as it should be. This commit hopefully changes that.
This changes the interface to MessagingController and the way flags are
updated in the database. Now messages aren't changed one by one but in
batches of 500. This should give better performance, but breaks the
unread and flagged count. I'm not very sad about this, because now we
can move towards only displaying the number of unread/flagged messages
in the local database.
Missing:
- UI support for threading when polling
- code to upgrade existing installations
- UI elements to switch from/to threaded display mode
- threading of messages with same subject
* rbayer/IMAPsearch: (21 commits)
More cleanup
Code Cleanup getRemoteSearchFullText -> isRemoteSearchFullText line wraps for preference items
Refactor to allow fetching of extra search results beyond original request. Most code moved out of ImapStore and ImapFolder and into MessagingController.searchRemoteMessagesSynchronous. Should make it easier to add remoteSearch for other server types.
Prevent delete of search results while search results open
remove duplicated code block
Don't hide Crypto when IMAPsearch disabled
Code Style Cleanup: Tabs -> 4 spaces Remove trailing whitespace from blank lines
tabs -> spaces (my bad...)
Fix opening of folders to be Read-Write when necessary, even if they were previously opened Read-Only.
add missing file
Working IMAP search, with passable UI.
UI improvements
Simple help info when enabling Remote Search
Dependency for preferences
Basic IMAP search working
On my emulator, it takes 70ms instead of 250ms.
On a very specific hardware, it takes 0,5s instead of 4,1s.
I willingly did not indent the code between my try/catch (for the patch to be readable).
