\r
86 Ok, I'll check some further. I am checking whether nm_thread is NULL
\r
87 though, the preceding code is as follows
\r
88 (astroid/src/modes/thread_index/thread_index.cc:258):
\r
92 notmuch_threads_valid (threads);
\r
93 notmuch_threads_move_to_next (threads)) {
\r
95 notmuch_thread_t * thread;
\r
96 thread =3D notmuch_threads_get (threads);
\r
98 if (thread =3D=3D NULL) {
\r
99 log << error << "ti: error: could not get thread." << endl;
\r
100 throw database_error ("ti: could not get thread (is NULL)");
\r
103 /* test for revision discarded */
\r
104 const char * ti =3D notmuch_thread_get_thread_id (thread);
\r
105 if (ti =3D=3D NULL) {
\r
106 log << error << "ti: revision discarded, trying to reopen." << endl=
\r
109 refresh (all, current_thread + count, false);
\r
114 NotmuchThread *t =3D new NotmuchThread (thread); // get_tags is insid=
\r
117 notmuch_thread_destroy (thread);
\r
121 (note that there is a bit of code there trying to determine whether the
\r
122 db is still valid, or needs to be re-opened)
\r
