[reSIProcate] DnsUtil.cxx

[Mike Hubbard]

Hi Scott,

 

The delay occurs every time I start the application.  It is the
getaddrinfo() API call that is causing the delay.

Hi Mike,

 

I have not noticed this problem on my systems (Windows 7 with IPv6 enabled).
I have some applications using resip statically and some using it in a DLL.
Does the delay only happen when the machine is starting up, or everytime you
start your application?  Are you able to put a break point in
DnsUtil::getLocalHostName to see which API is causing the delay?   Note:
getLocalHostName also calls initNetwork - which calls WSAStartup.

Hello,

 

I noticed in the most recent version of reciprocate that the routine
getLocalHostName() in the file DnsUtil.cxx has changed.  This routine seems
to be called by Helper.cxx in the following line of code:

 

static Data localhostname = DnsUtil::getLocalHostName();

 

This occurs when my .dll is loaded even  before the first line of the main()
routine is executed in the .exe.  On certain machines (mostly Windows 7 with
IPv6 enabled) the new call to getaddrinfo() is taking over 2 minutes to
return.  Then my code breaks on the first line of the main() function.

 

Is anyone else experiencing a similar problem?  If so, do you have any
advice?

 

Thanks in advance,

Mike
