Yes there was a change to the Database constructor in the notmuch2
python module in 0.34.2. It now uses the library to search for
configuration files and databases, so the semantics are a bit
different. But it is also possible that that default for the config
argument should be changed.
Can you try
with Database(config=Database.CONFIG.SEARCH) as db:
@Floris: when I made the change to the Database constructor, I chose the
default as CONFIG.NONE because this matched the previous semantics
_except_ for finding the database path. But since I don't want to use
the ad hoc default_path method anymore, maybe a better default would be
CONFIG.SEARCH. I guess most users of the python bindings will be OK with
the the configuration values in .notmuch-config being loaded by default.
What do you think?
