Hi,
this should allow me to do what I wish to accomplish. The message
deletion is still a problem though, I can see two options at the moment:
a) output during notmuch new to a hook or a list somewhere deleted files.
if list: notmuch will not handle this list, only append to it and
the user must
purge it when it is safe to do so.
if hook: for my purposes I would just create a hook appending to the
list. as a minimum I think thread_id, message_id and revision number
should be included.
b) maintain a full list of deleted / dead messages. a user initiated
purge can clean this from the database. a tag could be used for this,
so that clients can ignore unlinked/deleted/dead messages. this
differs from a 'deleted' message (IMAP/Maildir context) that has not
yet been expunged so there is confusion to be avoided.
a garbage collection function and interface must also be set up, but
this one is probably simple.
in most cases I think a) would be sufficient, and probably much easier
to do. it might be slow in cases where large amounts of messages have been
deleted, but this is seldom the case for me at least.
cheers, gaute
