diff src/imap/cmd-thread.c @ 8146:70b53e9b232e HEAD
Rewrote thread indexing code. It's a lot simpler and takes less disk space.
We no longer try to keep a hash table and the entire thread tree stored on
disk. Instead we keep a simple Message-ID string (actually just "uid, ref#"
pointer) -> unique index number mapping on disk, read it to memory and use
it to build the thread tree. After the initial build the thread tree is
still updated incrementally.
