The goal of mailstore abstraction is to allow notmuch to store tags
together with email messages. The abstract interface is needed because
people want to use different ways of storing their emails. Currently,
there exists implementation for two types of mailstore - plain files
and maildir. It is expected that additional git-based mailstore will
be developed later.
This patch contains only the interface changes. No functionality is
added, removed or changed.
A new configuration group [mailstore] is defined. Currently, there is
only one key called 'type' whose value determines the used mailstore.
The default value of this option (files) is the plain-file mailstore
currently implemented in notmuch.
This patch changes libnotmuch API (and ABI). The functions
notmuch_database_create() and notmuch_database_open() need additional
parameter to identify the type of mailstore, which is used to access
the messages.
If we want to preserve the API, it would be necessary to encode the
mailstore type into the 'path' parameter. For example the value
<path>#<type> (or <type>://<path>?) would mean use the mailstore of
given 'type' located at 'path'. If we cannot find the type we would
assuse the default mailstore.

The code for detection of new files in the mailstore and their
addition to the database is moved from notmuch-new.c to
lib/mailstore-files.c, where it is called by the abstract mailstore
interface.
The code was only changed to allow the progress reporting functions to
be implemented outside of notmuch library, as can be seen by
git diff HEAD^ -C

From: Michal Sojka @ 2010-04-08 14:42 UTC (permalink / raw)
To: notmuch
This patch modifies notmuch binary to access the messages through mail
store interface, so that non-file based mail stores can also be
implemented.
The API of notmuch library was changed. Now,
notmuch_message_get_filename() returns relative file name with respect
to the database path. As a result, notmuch show also outputs relative
paths so that MUAs need to be changed.
