[PATCH 0/5] lib: make folder: prefix literal

[Jani Nikula]

Hi all, this series makes the folder: search prefix literal, or switches
it from a probabilistic prefix to a boolean prefix. With this, you have
to give the path from the maildir root to the folder you want in full,
including the maildir cur/new component, if any. Examples:

folder:cur
folder:foo/bar
folder:""

The last one can be used to refer to the maildir root (note that in
shell you'll need quoting to pass the double quotes to xapian,
folder:'""').

The old probabilistic folder: prefix is problematic in a number of
ways. It's not possible to refer to the maildir root. It does stemming,
so "inboxing" would match "inbox" too. "cur" for the folder in maildir
root would match all "cur" folders across the maildir hierarchy. Likely
some others I forgot.

WARNING! The change requires a database format version bump, and a
database upgrade, which is automatically done on 'notmuch new'. The
upgrade is irreversible if you want to try this on your database! A
complete database rebuild is required for reverting the database format
version. Make sure your backups are in order!

The series includes some tests, including an initial upgrade test, along
with a test database in the previous format version.


BR,
Jani.
