From: Carl Worth Date: Tue, 24 Nov 2009 04:12:57 +0000 (-0800) Subject: notmuch search: Remove the chunked-searching hack. X-Git-Tag: 0.1~341 X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=1fd8b7866f189a66e4491b01452f476371759f91;p=notmuch.git notmuch search: Remove the chunked-searching hack. 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). --- diff --git a/lib/notmuch.h b/lib/notmuch.h index 260cc22d..9b40fb69 100644 --- a/lib/notmuch.h +++ b/lib/notmuch.h @@ -322,14 +322,6 @@ notmuch_query_set_sort (notmuch_query_t *query, notmuch_sort_t sort); * object is owned by the query and as such, will only be valid until * notmuch_query_destroy. * - * The 'first' and 'max_threads' arguments can be used to obtain - * partial results from the search.
