From: Carl Worth Date: Wed, 8 Dec 2010 00:33:29 +0000 (-0800) Subject: notmuch search: Fix to display authors in date order. X-Git-Tag: debian/0.6_254~225 X-Git-Url: https://git.notmuchmail.org/git?p=notmuch;a=commitdiff_plain;h=b099fc9ea77e7d1fc68b5dd10d1d3adc764c6efc notmuch search: Fix to display authors in date order. Previously, the authors of the thread were displayed in reverse-chronological order, which was fairly confusing. --- diff --git a/lib/thread.cc b/lib/thread.cc index 3738baa9..31c655b6 100644 --- a/lib/thread.cc +++ b/lib/thread.cc @@ -31,7 +31,7 @@ struct _notmuch_thread { GHashTable *authors_hash; GPtrArray *authors_array; GHashTable *matched_authors_hash; - int has_non_matched_authors; + GPtrArray *matched_authors_array; char *authors; GHashTable *tags; @@ -56,11 +56,16 @@ _notmuch_thread_destructor (notmuch_thread_t *thread) thread->authors_array = NULL; } + if (thread->matched_authors_array) { + g_ptr_array_free (thread->matched_authors_array, TRUE); + thread->matched_authors_array = NULL; + } + return 0; } -/* Add each author of the thread to the thread's authors_hash and the - * thread's authors_array. */ +/* Add each author of the thread to the thread's authors_hash and to + * the thread's authors_array. */ static void _thread_add_author (notmuch_thread_t *thread, const char *author) @@ -82,7 +87,7 @@ _thread_add_author (notmuch_thread_t *thread, } /* Add each matched author of the thread to the thread's - * matched_authors_hash and to the thread's authors string. */ + * matched_authors_hash and to the thread's matched_authors_array. */ static void _thread_add_matched_author (notmuch_thread_t *thread, const char *author) @@ -100,42 +105,54 @@ _thread_add_matched_author (notmuch_thread_t *thread, g_hash_table_insert (thread->matched_authors_hash, author_copy, NULL); - if (thread->authors) - thread->authors = talloc_asprintf (thread, "%s, %s", - thread->authors, - author); - else - thread->authors = author_copy; + g_ptr_array_add (thread->matched_authors_array, author_copy); } -/* Copy any authors from the authors array that were not also matched - * authors onto the end of the thread's authors string. - * We use a '|' to separate matched and unmatched authors. */ +/* Construct an authors string from matched_authors_array and + * authors_array.
