From 00ae13f96630dc5c2a9add25a4337710f8fcdaf5 Mon Sep 17 00:00:00 2001 From: Daniel Stenberg Date: Mon, 11 Sep 2006 20:25:13 +0000 Subject: - Guilherme Balena Versiani: I noted a strange BUG in Win32 port (ares_init.c/get_iphlpapi_dns_info() function): when I disable the network by hand or disconnect the network cable in Windows 2000 or Windows XP, my application gets 127.0.0.1 as the only name server. The problem comes from 'GetNetworkParams' function, that returns the empty string "" as the only name server in that case. Moreover, the Windows implementation of inet_addr() returns INADDR_LOOPBACK instead of INADDR_NONE. --- ares/CHANGES | 10 ++++++++++ ares/ares_init.c | 3 ++- 2 files changed, 12 insertions(+), 1 deletion(-) (limited to 'ares') diff --git a/ares/CHANGES b/ares/CHANGES index 0a927c284..2e0393b18 100644 --- a/ares/CHANGES +++ b/ares/CHANGES @@ -1,5 +1,15 @@ Changelog for the c-ares project +* September 11 2006 + +- Guilherme Balena Versiani: I noted a strange BUG in Win32 port + (ares_init.c/get_iphlpapi_dns_info() function): when I disable the network + by hand or disconnect the network cable in Windows 2000 or Windows XP, my + application gets 127.0.0.1 as the only name server.
