We only rarely need to actually open the database for writing, but we
always create a Xapian::WritableDatabase. This has the effect of
preventing searches and like whilst updating the index.

More fallout from _get_header now returning "" for missing headers.
The bug here is that we would no longer detect that a file is not an
email message and give up on it like we should.
And this time, I actually audited all callers to
notmuch_message_get_header, so hopefully we're done fixing this
bug over and over.
There's been a fair amount of fallout from when we changed
message_file_get_header from returning NULL to returning "" for
missing headers. This is yet more fallout from that, (where we were
accepting an empty message-ID rather than generating one like we want
to).
This was recently introduced in commit:
64c03ae97f
which was adding extra checks to avoid adding a self-referencing
message.
How many times am I going to fix a dumb regression like this and say
"we really need a test suite" before I actually sit down and write the
test suite?
We had exposed this to the internal implementation for a short time,
(only while we had the silly code fetching In-Reply-To values from
message files instead of from the database). Make this private again
as it should be.
Maybe ths lack of this documentation is why I forgot we were actually
storing this and wrote the ugly code to fetch In-Reply-To from message
files rather than from the database.
Which is more consistent with the XREFERENCE prefix used in the terms
in the database. Also remove some stale documentation describing the
removal of resolved references from the database (we no longer do
this).
In our scheme it's illegal for any message to refer to itself, (nor
would it be useful for anything anyway). Cut these self-references off
at the source, before they trip up any internal errors.
This function has only one caller, and that one caller was passing the
same value for both talloc_owner and the notmuch database. Dropping
the redundant argument simplifies the documentation of this function
considerably.
When this function was originally written, the 'message' object was
always destroyed locally, so I thought it would be good to use a NULL
talloc context to make it more obvious if there was any leak.
Since then, however, this function has been changed to optionally
return the added message, and in that case we *don't* free the message
locally, so let's let the database be the talloc context.
We never did export any interface to get at these, and when I went to
use these, I found them inadequate, (because I wanted to distinguish
address found in from: from those found in To:). Meanwhile, it was
easy enough to extract addresses with a search like:
notmuch show tag:sent | grep ^To:
so the storage of contact terms was just wasting space. Stop that.
This will allow for things like the database path to be specified
without any cheesy NOTMUCH_BASE environment variable. It also will
allow "notmuch reply" to recognize the user's email address when
constructing a reply in order to do the right thing, (that is, to use
the user's address to which mail was sent as From:, and not to reply
to the user's own addresses).
With this change, the "notmuch setup" command is now strictly for
changing the configuration of notmuch. It no longer creates the
database, but instead instructs the user to call "notmuch new" to do
that.
