From a37d5f5976de07b36141aa6b4a98cf913a3cf2fe Mon Sep 17 00:00:00 2001 From: David Bremner Date: Sun, 14 Feb 2021 20:55:55 -0400 Subject: [PATCH] test: Fix race condition in T568-lib-thread.sh The assignment of thread-ids is (apparently) non-deterministic in a way that mostly seems to show up on multicore machines. In my tests the number is different from that previously assumed by this test about 15% of the time on a 50 thread (25 core) Xeon. Since message id's are fixed, use a message known to be in the thread of interest to pick out the correct thread-id. --- test/T568-lib-thread.sh | 10 ++++++++-- 1 file changed, 8 insertions(+), 2 deletions(-) diff --git a/test/T568-lib-thread.sh b/test/T568-lib-thread.sh index ac13d986..088e66dd 100755 --- a/test/T568-lib-thread.sh +++ b/test/T568-lib-thread.sh @@ -8,6 +8,11 @@ add_email_corpus test_begin_subtest "building database" test_expect_success "NOTMUCH_NEW" +test_begin_subtest "finding thread" +THREAD=$(notmuch search --output=threads id:20091117190054.GU3165@dottiness.seas.harvard.edu) +count=$(notmuch count $THREAD) +test_expect_equal "$count" "7" + cat <<'EOF' > c_tail if (stat) { const char *stat_str = notmuch_database_status_string (db); @@ -30,7 +35,7 @@ int main (int argc, char** argv) notmuch_thread_t *thread = NULL; notmuch_threads_t *threads = NULL; notmuch_query_t *query = NULL; - const char *id = "thread:0000000000000009"; + const char *id = "${THREAD}"; stat = notmuch_database_open_verbose (argv[1], NOTMUCH_DATABASE_MODE_READ_WRITE, &db, &msg); if (stat != NOTMUCH_STATUS_SUCCESS) { @@ -52,10 +57,11 @@ cat c_head - c_tail <<'EOF' | test_C ${MAIL_DIR} printf("%d\n%s\n", thread != NULL, id2); } EOF +thread_num=${THREAD#thread:} cat < EXPECTED == stdout == 1 -0000000000000009 +${thread_num} == stderr == EOF test_expect_equal_file EXPECTED OUTPUT -- 2.45.2
