Since the build tree will populate content under the source tree
the test cannot reliably check that the source tree is pristine.
Simply skip most of the test in this case.
We no longer support CVS checkouts from the Git repository.
Drop the case from the CheckSourceTree test. This will also
prevent the test from running and failing when CVS is found
but Git is not.
If GIT_EXECUTABLE is not passed in, and is not available from
DartConfiguration.tcl or CTestConfiguration.ini, then make one
more last ditch attempt to get it from Update.xml, if there is
an Update.xml. For dashboards that have successfully done a
ctest_update call, there should be an Update.xml in the Testing
subdir of the binary tree. Parse that file for the git executable
recorded in the <UpdateCommand> element.
And make this test pass on those RogueResearch dashboard machines!
If GIT_EXECUTABLE is not passed into the test, but the source
tree is a git checkout, then use GitCommand or UpdateCommand
from the ctest ini file to set its value. Presumably, a dashboard
running the test suite had to have set this properly in order
to do the ctest_update step.
Echo results of calling git status before exiting with
an error. Add one special case so that the test may pass
on the dashmacmini2 continuous dashboard, despite a 'git
status' non-zero return code. More logic like this may
be required. I will re-evaluate based on tomorrow's
nightly dashboard runs.
Additionally, output some more information in both cvs
and git cases. When it is a cvs checkout, echo the contents
of CVS/Root and CVS/Repository to the test output. When it
is a git checkout, echo the output of 'git branch -a'.
This will allow us to see more details about any given CMake
source tree right in the CDash results for this test.
