From 07862531152bc3b93590f1a2010080c87474c92b Mon Sep 17 00:00:00 2001 From: Azat Khuzhin Date: Thu, 19 Jan 2017 20:34:41 +0300 Subject: [PATCH] test/dns: run async resolving after sync one (to avoid timeouts) If system resolver (sync one) will respond too slow, then we can fail async request and evdns will retransmit tham again, but evdns server will accept that failed requets, so we will have not 2 requests but 4. Reproduced on centos box sometimes. --- test/regress_dns.c | 18 +++++++++--------- 1 file changed, 9 insertions(+), 9 deletions(-) diff --git a/test/regress_dns.c b/test/regress_dns.c index 11c015c5..feef0222 100644 --- a/test/regress_dns.c +++ b/test/regress_dns.c @@ -1250,15 +1250,6 @@ test_bufferevent_connect_hostname(void *arg) bufferevent_setcb(be5, NULL, NULL, be_connect_hostname_event_cb, &be5_outcome); - /* Launch an async resolve that will fail. */ - tt_assert(!bufferevent_socket_connect_hostname(be1, dns, AF_INET, - "nosuchplace.example.com", listener_port)); - /* Connect to the IP without resolving. */ - tt_assert(!bufferevent_socket_connect_hostname(be2, dns, AF_INET, - "127.0.0.1", listener_port)); - /* Launch an async resolve that will succeed. */ - tt_assert(!bufferevent_socket_connect_hostname(be3, dns, AF_INET, - "nobodaddy.example.com", listener_port)); /* Use the blocking resolver.
