Hi Pekka,
Just noticed this in our testing group. Pretty much tells me no one is
using TCP as a transport.
Back between 1.12.5 and 1.12.6, you removed the
if (su_setblocking(socket, 0) < 0)
return *return_reason = "su_setblocking", -1;
From tport_type_tcp.c and tport_type_sctp.c in the
tport_tcp_init_secondary() functions.
This causes the TCP sockets to be blocking and the connect() to hang
until a connection is established or it times out.
For us, running single threaded, causes the stack to hang for 180
seconds if the registrar is configured improperly, then the retry and
hang again. Basically causing our application to be unresponsive. Worse
than a crash for since at least with a crash, we can restart.
I tracked down the patch that did this. Not much help, but here it is:
Changes to libsofia-sip-ua/tport/tport_type_tcp.c:
Thu Feb 22 12:33:47 PST 2007 Pekka Pessi <pekka.pe...@nokia.com>
* su_addrinfo.c: fixed Solaris addrinfo() which returns 0 in ai_protocol
This caused an assertion failure in tport.c on Solaris.
Any chance you remember why this change to the blocking mode of the TCP
sockets was made ?
Thanks,
Colin..
