Summary: Slow execution of tests
Description:
Tests execution is very slow if we didn't use CDash.
time make test
Running tests...

...... (the longer one is 0.03 sec)....
.......
real 0m10.473s
user 0m0.060s
sys 0m0.043s
So take 10 seconds to execute 36 tests of ~0.01 seconds. The longer was to wait
passing the first test.
While tracing in GDB when waiting on first test :

The problem came from : int res = cmCTest::HTTPRequest(url, cmCTest::HTTP_GET,
response, "", "", 3); in GetCDashVersion().
When not using CDash on projects I only use "enable_testing()" in CMakeLists.txt
so didn't set CDashDropSite (maybe this is a mistake, but what to setup if I
didn't intend to use cdash ???).
In such case, DropSite is empty, so requested url is
"http:///api/getversion.php"; which lead to "http:" as domain lookup into curl.
It finish by waiting the 3 second before timout ... for nothing.
Partialy related to this commit : 41fcf6e1558cb3ef4639928f87d58531b45fe237.
Maybe another one interfer with it by setting an empty drop site by default as I
observe this bug for a couple of months.
Also observed on a Gentoo, ubuntu x86_64.
Steps to Reproduce:
Setup a project with fast tests and only setup "enable_tesing()" in
CMakeLists.txt. Do not consider usage of cdash and simply compile and run tests
:
mkdir build
cd build
cmake ..
make
make test
You will wait at least 3 seconds.
Additional Information:
Suggest to simply add of if statement before starting the request and bypass
this when drop site is empty.
