Hello,
Is there a built-in way to get a ctest -S script to checkout and pull from a
git branch other than 'master'? I can't seem to find a way to so this and
there is no mention of branches at all in the official documentation:
https://cmake.org/cmake/help/v3.6/command/ctest_update.html?highlight=ctest_update
and there is no mention of "branch" at:
https://cmake.org/Wiki/CMake/Testing_With_CTest
Currently, I see code that people have written which is explicitly checking out
and updating the desired branch after ctest_update() is called (e.g. this what
TribitsCTestDriverCore.cmake does). Therefore, this CTest code is really just
using ctest_update() to do a `git fetch` on the external repo. In this case,
if the local branch is changed to a tracking branch, then will ctest_update()
leave that tracking branch as is and just pull from the tracking branch the
next time the ctest -S script is called? If that is the case, then I would
expect CTest to report the correct list of "updated files". But if
ctest_update() instead switches back to the 'master' branch and then does the
pull, then it will likely report the wrong list of "updated files".
I can dig into the source code for CTest to see what it actually does but it
would be nice to have direct support for choosing the branch or at the very
least just documenting the current behavior and describe the best way to work
around the issue.
Thanks,
-Ross
