lib: add function to get the number of threads matching a search

2011-11-15T23:12:32Z

Add function notmuch_query_count_threads() to get the number of threads matching a search. This is done by performing a search and figuring out the number of unique thread IDs in the matching messages, a significantly heavier operation than notmuch_query_count_messages().

Mark some structures in the library interface with visibility=default attribute.

2011-05-11T20:27:15Z

As of gcc 4.6, there are new warnings from -Wattributes along the lines of: warning: ‘_notmuch_messages’ declared with greater visibility than the type of its field ‘_notmuch_messages::iterator’ [-Wattributes] To squelch these, we decorate all such containing structs with __attribute__((visibility("default"))). We take care to let only the C++ compiler see this, (since the C compiler would otherwise warn about ignored visibility attributes on types).

Simplify _notmuch_doc_id_set_init interface.

2011-01-31T02:01:56Z

Don't require the caller of _notmuch_doc_id_set_init to pass in a correct bound; instead compute it from the array. This simplifies the caller and makes this interface easier to use correctly.

Remove code repetition in the doc ID bitmap code.

2011-01-31T01:58:27Z

Remove the repeated "sizeof (doc_ids->bitmap[0])" that bothered cworth by instead defining macros to compute the word and bit offset of a given bit in the doc ID set bitmap.

Optimize thread search using matched docid sets.

2010-12-08T00:40:05Z

This reduces thread search's 1+2t Xapian queries (where t is the number of matched threads) to 1+t queries and constructs exactly one notmuch_message_t for each message instead of 2 to 3. notmuch_query_search_threads eagerly fetches the docids of all messages matching the user query instead of lazily constructing message objects and fetching thread ID's from term lists. _notmuch_thread_create takes a seed docid and the set of all matched docids and uses a single Xapian query to expand this docid to its containing thread, using the matched docid set to determine which messages in the thread match the user query instead of using a second Xapian query. This reduces the amount of time required to load my inbox from 4.523 seconds to 3.025 seconds (1.5X faster).

lib: Eliminate some redundant includes of xapian.h

2010-11-02T06:24:40Z

Most files including this already include database-private.h which includes xapian.h already.

lib: Add two functions: notmuch_query_get_query_string and _get_sort

2010-10-28T17:30:26Z

It can be handy to be able to query these settings from an existing query object.

lib: Fix notmuch_query_search_threads to return NULL on any Xapian exception.

2010-10-23T00:56:58Z

Previously, if the underlying search_messages hit an exception and returned NULL, this function would ignore that and return a non-NULL, (but empty) threads object. Fix this to properly propagate the error.

lib: Ensure notmuch_query_search_messages returns NULL on an exception.

2010-04-24T14:27:50Z

Previously, this function may have segfaulted immediately after reporting the exception.

query.cc: allow to return query results unsorted

2010-04-21T23:06:05Z

Previously, we always sorted the returned results by some string value, (newest-to-oldest by default), however in some cases (as when applying tags to a search result) we are not interested in any special order. This introduces a NOTMUCH_SORT_UNSORTED value that does just that. It is not used at the moment anywhere in the code. Signed-off-by: Sebastian Spaeth
