From 1718823b803bc8170e1692b3a0d9420d89b0c33e Mon Sep 17 00:00:00 2001 From: Evangelos Ribeiro Tzaras Date: Thu, 16 Sep 2021 16:51:42 +0200 Subject: [PATCH] sip: Do not fail if CallsNetworkWatch is unavailable In this case network changes will not be detected. Additionally fall back to binding on all network interfaces (in this case a user will have problems when using multiple network interfaces, but there is really not much we can do without a functioning CallsNetworkWatch). --- plugins/sip/calls-sip-origin.c | 17 ++++++++++++----- 1 file changed, 12 insertions(+), 5 deletions(-) diff --git a/plugins/sip/calls-sip-origin.c b/plugins/sip/calls-sip-origin.c index 32fd80a..a193d19 100644 --- a/plugins/sip/calls-sip-origin.c +++ b/plugins/sip/calls-sip-origin.c @@ -803,8 +803,10 @@ setup_nua (CallsSipOrigin *self) if (!sip_test_env || sip_test_env[0] == '\0') { CallsNetworkWatch *nw = calls_network_watch_get_default (); - ipv4_bind = calls_network_watch_get_ipv4 (nw); - ipv6_bind = calls_network_watch_get_ipv6 (nw); + if (nw) { + ipv4_bind = calls_network_watch_get_ipv4 (nw); + ipv6_bind = calls_network_watch_get_ipv6 (nw); + } } uuid = nua_generate_instance_identifier (self->ctx->home); @@ -1461,9 +1463,14 @@ calls_sip_origin_init (CallsSipOrigin *self) { const char *sip_test_env = g_getenv ("CALLS_SIP_TEST"); - if (!sip_test_env || sip_test_env[0] == '\0') - g_signal_connect_swapped (calls_network_watch_get_default (), "network-changed", - G_CALLBACK (on_network_changed), self); + if (!sip_test_env || sip_test_env[0] == '\0') { + CallsNetworkWatch *nw = calls_network_watch_get_default (); + if (nw) + g_signal_connect_swapped (calls_network_watch_get_default (), "network-changed", + G_CALLBACK (on_network_changed), self); + else + g_warning ("Network watch unavailable.
