lib: make notmuch_threads_valid return FALSE when passed NULL

2014-01-25T00:20:54Z

Without this patch, the example code in the header docs crashes for certain invalid queries (see id:871u00oimv.fsf@approx.mit.edu)

query: bind queries to database objects

2013-11-02T13:20:01Z

The queries don't really work after a database is closed, and we would like them to be freed if the database is destroyed. Acknowledged-by: David Bremner Signed-off-by: Felipe Contreras

lib: add NOTMUCH_EXCLUDE_FLAG to notmuch_exclude_t

2013-06-25T05:53:16Z

Add NOTMUCH_EXCLUDE_FLAG to notmuch_exclude_t so that it can cover all four values of search --exclude in the cli. Previously the way to avoid any message being marked excluded was to pass in an empty list of excluded tags: since we now have an explicit option we might as well honour it. The enum is in a slightly strange order as the existing FALSE/TRUE options correspond to the new NOTMUCH_EXCLUDE_FLAG/NOTMUCH_EXCLUDE_TRUE options so this means we do not need to bump the version number. Indeed, an example of this is that the cli count and show still use FALSE/TRUE and still work.

lib: add --exclude=all option

2013-05-14T00:32:03Z

Adds a exclude all option to the lib which means that excluded messages are completely ignored (as if they had actually been deleted).

bitmap:improve memory usage using CHAR_BITS and unsigned CHAR

2013-02-16T00:05:10Z

Using char instead of int allows for simpler definitions of the DOCIDSET macros so the code is easier to understand and consistent with respect to memory-usage. Estimated reduction of memory-usage for bitmap about 8 times.

lib: change default for notmuch_query_set_omit_excluded

lib: fix an exclude bug

2012-03-18T12:14:23Z

When the exclude tags contain a tag that does not occur anywhere in the Xapian database the exclusion fails. We modify the way the query is constructed to `work around' this. (In fact the new code is cleaner anyway.) It also seems to fix another exclusion failure bug reported by jrollins but we have not yet worked out why it helps in that case.

lib: Add exclude query debug output

lib: Expose query debug output via an environment variable

2012-03-18T12:14:22Z

Allow query debugging to be enabled at run-time by setting the NOTMUCH_DEBUG_QUERY environment variable to a non-empty string. Previously, enabling query debugging required recompiling, but parsed queries are often useful for tracking down bugs in situations where recompiling is inconvenient.

lib: Add the exclude flag to notmuch_query_search_threads

2012-03-02T12:28:39Z

Add the NOTMUCH_MESSAGE_FLAG_EXCLUDED flag to notmuch_query_search_threads. Implemented by inspecting the tags directly in _notmuch_thread_create/_thread_add_message rather than as a Xapian query for speed reasons. Note notmuch_thread_get_matched_messages now returns the number of non-excluded matching messages. This API is not totally desirable but fixing it means breaking binary compatibility so we delay that.
