From b5c3feda1788301bea7f1dd4f9bb240d13862bd0 Mon Sep 17 00:00:00 2001 From: Kamil Dudka Date: Fri, 30 Jul 2010 00:47:49 +0200 Subject: NTLM tests: boost coverage by forcing the hostname A shared library tests/libtest/.libs/lihostname.so is preloaded in NTLM test-cases to override the system implementation of gethostname(). It makes it possible to test the NTLM authentication for exact match, and this way test the implementation of MD4 and DES. If LD_PRELOAD doesn't work, a debug build willl also workk as debug builds are now made to prefer a specific environment variable and will then return that content as host name instead of the actual one. Kamil wrote the bulk of this, Daniel Stenberg polished it. --- lib/curl_gethostname.c | 52 ++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 52 insertions(+) create mode 100644 lib/curl_gethostname.c (limited to 'lib/curl_gethostname.c') diff --git a/lib/curl_gethostname.c b/lib/curl_gethostname.c new file mode 100644 index 000000000..5a8c6494b --- /dev/null +++ b/lib/curl_gethostname.c @@ -0,0 +1,52 @@ +/*************************************************************************** + * _ _ ____ _ + * Project ___| | | | _ \| | + * / __| | | | |_) | | + * | (__| |_| | _ <| |___ + * \___|\___/|_| \_\_____| + * + * Copyright (C) 1998 - 2010, Daniel Stenberg, , et al. + * + * This software is licensed as described in the file COPYING, which + * you should have received as part of this distribution.
