2010-11-01lib: Eliminate some redundant includes of xapian.hCarl Worth
Most files including this already include database-private.h which includes xapian.h already.
2010-10-28lib: Add two functions: notmuch_query_get_query_string and _get_sortCarl Worth
It can be handy to be able to query these settings from an existing query object.
2010-10-22lib: Fix notmuch_query_search_threads to return NULL on any Xapian exception.Carl Worth
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.
2010-04-24lib: Ensure notmuch_query_search_messages returns NULL on an exception.Carl Worth
Previously, this function may have segfaulted immediately after reporting the exception.
2010-04-21query.cc: allow to return query results unsortedSebastian Spaeth
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 <Sebastian@SSpaeth.de>
2010-04-21Name thread based on matching msgs instead of first msg.Jesse Rosenthal
At the moment all threads are named based on the name of the first message in the thread. However, this can cause problems if people either start new threads by replying-all (as unfortunately, many out there do) or change the subject of their mails to reflect a shift in a thread on a list. This patch names threads based on (a) matches for the query, and (b) the search order. If the search order is oldest-first (as in the default inbox) it chooses the oldest matching message as the subject. If the search order is newest-first it chooses the newest one. Reply prefixes ("Re: ", "Aw: ", "Sv: ", "Vs: ") are ignored (case-insensitively) so a Re: won't change the subject. Note that this adds a "sort" argument to _notmuch_thread_create and _thread_add_matched_message, so that when constructing the thread we can be aware of the sort order.

2010-04-09lib: Handle "*" as a query string to match all messages.Carl Worth
This seems like a generally useful thing to support, (but the previous support through an empty string was not convenient for some users, (such as the command-line client).
2010-03-09lib: Rename iterator functions to prepare for reverse iteration.Carl Worth
We rename 'has_more' to 'valid' so that it can function whether iterating in a forward or reverse direction. We also rename 'advance' to 'move_to_next' to setup parallel naming with the proposed functions 'move_to_first', 'move_to_last', and 'move_to_previous'.
2010-01-09lib: Explicitly set BoolWeight when searching.Carl Worth
All notmuch searches currently sort by value (either date or message ID) so it's just wasted effort for Xapian to compute relevance values for each result. We now explicitly tell Xapian that we're uninterested in the relevance values.
2009-11-27Silence compiler warning by initializing a variable.Jeffrey C. Ollie
If Xapian threw an exception on notmuch_query_count_messages the count variable could be used uninitialized. Initialize count to solve the problem. Signed-off-by: Jeffrey C. Ollie <jeff@ocjtech.us>
2009-11-24lib/messages.c: Make message searches stream as well.Carl Worth
Xapian provides an interator-based interface to all search results. So it was natural to make notmuch_messages_t be iterator-based as well. Which we did originally. But we ran into a problem when we added two APIs, (_get_replies and _get_toplevel_messages), that want to return a messages iterator that's *not* based on a Xapian search result. My original compromise was to use notmuch_message_list_t as the basis for all returned messages iterators in the public interface. This had the problem of introducing extra latency at the beginning of a search for messages, (the call would block while iterating over all results from Xapian, converting to a message list). In this commit, we remove that initial conversion and instead provide two alternate implementations of notmuch_messages_t (one on top of a Xapian iterator and one on top of a message list). With this change, I tested a "notmuch search" returning *many* results as previously taking about 7 seconds before results started appearing, and now taking only 2 seconds.
2009-11-23lib/query: Drop the first and max_messages arguments from search_messages.Carl Worth
These only existed to support the chunky-searching hack, but that was recently dropped anyway.
2009-11-23lib/query: Fix notmuch_threads_t to stream results rather than blocking.Carl Worth
Previously, notmuch_query_search_threads would do all the work, so the caller would block until all results were processed. Now, we do the work as we go, as the caller iterates with notmuch_threads_next. This means that once results start coming back from "notmuch search" they just keep continually streaming. There's still some initial blocking before the first results appear because the notmuch_messages_t object has the same bug (for now).
2009-11-23notmuch search: Remove the chunked-searching hack.Carl Worth
This was a poor workaround around the fact that the existing notmuch_threads_t object is implemented poorly. It's got a fine iterartor-based interface, but the implementation does all of the work up-front in _create rather than doing the work incrementally while iterating. So to start fixing this, first get rid of all the hacks we had working around this. This drops the --first and --max-threads options from the search command, (but hopefully nobody was using them anyway---notmuch.el certainly wasn't).
2009-11-23Add 'notmuch count' command to show the count of matching messagesKeith Packard
Getting the count of matching threads or messages is a fairly expensive operation. Xapian provides a very efficient mechanism that returns an approximate value, so use that for this new command. This returns the number of matching messages, not threads, as that is cheap to compute. Signed-off-by: Keith Packard <keithp@keithp.com>
2009-11-22Catch and optionally print about exception at database->flush.Carl Worth
If an earlier exception occurred, then it's not unexpected for the flush to fail as well. So in that case, we'll silently catch the exception. Otherwise, make some noise about things going wrong at the time of flush.
2009-11-22Print information about where Xapian exception occurred.Carl Worth
Previously, our Xapian exception reports where identical so they were hard to track down.
2009-11-21When a search query triggers a Xapian exception, log what the query was.Eric Anholt
In my script containing a series of queries to be run on new mail for setting up tags, it's nice to see which query I typed wrong. Signed-off-by: Eric Anholt <eric@anholt.net>
2009-11-19Allow lone "not" search operatorsAdrian Perez
As suggested by Keith in FLAG_PURE_NOT allows for expressions like: notmuch search NOT tag:inbox Note that this way a search like: notmuch search foobar NOT tag:inbox should not be written instead: notmuch search foobar AND NOT tag:inbox In my opinion, the latter feels more natural and is somewhat more explicit. It gives a better clue of what the search is about instead of assuming that an implicit AND operator is there.
2009-11-17notmuch search: Change default search order to be newest messages first.Carl Worth
This is what most people want for a _search_ command. It's often different for actually reading mail in an inbox, (where it makes more sense to have results displayed in chronological order), but in such a case, ther user is likely using an interface that can simply pass the --sort=oldest-first option to "notmuch search". Here we're also change the sort enum from NOTMUCH_SORT_DATE and NOTMUCH_SORT_DATE_REVERSE to NOTMUCH_SORT_OLDEST_FIRST and NOTMUCH_SORT_NEWEST_FIRST. Similarly we replace the --reverse option to "notmuch search" with two options: --sort=oldest-first and --sort=newest-first. Finally, these changes are all tracked in the emacs interface, (which has no change in its behavior).
2009-11-15lib/messages: Add new notmuch_message_list_t to internal interface.Carl Worth
Previously, the notmuch_messages_t object was a linked list built on top of a linked-list node with the odd name of notmuch_message_list_t. Now, we've got much more sane naming with notmuch_message_list_t being a list built on a linked-list node named notmuch_message_node_t. And now the public notmuch_messages_t object is a separate iterator based on notmuch_message_node_t. This means the interfaces for the new notmuch_message_list_t object are now made available to the library internals.
2009-11-14lib: Move notmuch_messages_t code from query.cc to new messages.cCarl Worth
The new object is simply a linked-list of notmuch_message_t objects, (unlike the old object which contained a couple of Xapian iterators). This works now by the query code immediately iterator over all results and creating notmuch_message_t objects for them, (rather than waiting to create the objects until the notmuch_messages_get call as we did earlier). The point of this change is to allow other instances of lists of messages, (such as in notmuch_thread_t), that are not directly related to Xapian search results.
2009-11-12notmuch search: Add support for a --reverse option to reverse sort order.Carl Worth
Note that the difference between thread results in date order and thread results in reverse-date order is not simply a matter of reversing the final results. When sorting in date order, the threads are sorted by the oldest message in the thread. When sorting in reverse-date order, the threads are sorted by the newest message in the thread. This difference means that we might want an explicit option in the interface to reverse the order, (even though the default will be to display the inbox in date order and global searches in reverse-date order).
2009-11-12notmuch search: Print the number of matched/total messages for each thread.Carl Worth
Note that we don't print the number of *unread* messages, but instead the number of messages that matched the search terms. This is in keeping with our philosophy that the inbox is nothing more than a search view. If we search for messages with an inbox tag, then that's what we'll get a count of. (And if somebody does want to see unread counts, then they can search for the "unread" tag.) Getting the number of matched messages is really nice when doing historical searches. For example in a search like: notmuch search tag:sent (where the "sent" tag has been applied to all messages originating from the user's email address)---here it's really nice to be able to see a thread where the user just mentioned one point [1/13] vs. really getting involved in the discussion [10/29].
2009-11-12notmuch search: Print all authors contributing to a thread.Carl Worth
We've now expanded the notmuch_thread_create function to fire off a secondary database query to find all the messages that belong to this particular thread. This allows us to now have the complete authors' list for the thread, and will also make it trivial to print accurate message counts for threads in the future.
2009-11-12notmuch_query_search_threads: Avoid returning more threads than asked for.Carl Worth
I thought it would be safe enough to return a few extra threads, (since we happened to already get the relevant messages out of the database). The problem is that then requires the caller to carefully read the number of threads returned and adjust its next "first" value accordingly. The interface is much simpler to use if we simply return exactly what is asked for and no more.
2009-11-12notmuch search: Fix a second bug in the change to support incremental searches.Carl Worth
The search was dropping the first thread from the results. When am I going to break down and write a test suite? It's long overdue now.
2009-11-12notmuch search: Fix to actually return something.Carl Worth
This serves me right for committing untested code. The notmuch_query_search_threads was totally broken, (it didn't properly treat -1 as being unlimited and instead returned no threads in that case).
2009-11-12libnotmuch: Underlying support for doing partial-results searches.Carl Worth
The library interface now allows the caller to do incremental searches, (such as one page of results at a time). Next we'll just need to hook this up to "notmuch search" and the emacs interface.
2009-11-09libify: Move library sources down into lib directory.Carl Worth
A "make" invocation still works from the top-level, but not from down inside the lib directory yet.
