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!
Git's diff-tree format has no '\n'-terminated blank line at the end of
its commit message body block if there are no diff lines. Instead the
message body is terminated by '\0' and there is no diff section. Teach
CTest to parse the format in this case.
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.
At this point, CTestTest3 causes more problems than it's worth.
It uses CVS to grab a remote (over the network) copy of kwsys
code for testing. This causes some sort of problem nearly every
night on the nightly CMake dashboards. Worse: it causes problems
on different machines on different nights, then the next day, it's
fine again. So: remove this test and monitor the coverage.
If we lose a significant portion of code coverage, I will revert
this commit and re-activate the test. However, if we do not lose
a significant portion of code coverage, I will remove the code
for the test as well as removing it from the CMakeLists.txt file.
Brad King and I discussed this over the last few weeks, and we both
think we have sufficient coverage of all the checkout and update code
in other locally (non-network) based tests.
On the other hand, even if we do take a mild hit on coverage temporarily,
it should be relatively easy to increase our coverage again by adding
bits to those other locally based tests.
The bootstrap script works under MSYS, so test it. Use a launcher batch
file since 'ctest --build-and-test' is a Windows program and will not
honor the shebang line in the script.
Even though this test is checking that the ctest running it can handle
test output without newlines we should run the just-built CMake binary.
This allows the MemCheck test mode to check the correct CMake.
Use 'git fetch' followed by 'git reset' to update the source tree. This
is better than 'git pull' because it can handle a rewritten upstream
branch and does not leave local modifications. After fetch, parse
FETCH_HEAD to find the merge head that 'git pull' would choose to track
the upstream branch. Then reset to the selected head.
In the normal fast-forward case the behavior remains unchanged.
However, now local modifications and commits will be erased, and
upstream rewrites are handled smoothly. This ensures that the upstream
branch is tested as expected.
Teach (create|run)_dashboard_script macros to treat the argument as the
name of a build tree. Append '.cmake' to generate the dashboard script
name. This allows future re-use of the macros for multiple test
scripts.
Use it from ExternalProject and the ExternalProject test's
CMakeLists file rather than having duplicate find_program calls.
Add logic so that we do not try to use *.cmd variants of git
programs when using the MSYS Makefiles generator. Should fix
the last remaining dashboard issue with the new ExternalProject
git support additions.
Also, correct minor problem regarding placement of the local git
repo during test execution. On clean builds, it was being placed
incorrectly because of the ../.. relative reference. Use an absolute
path to place the local git repo in the proper directory, and only
use the relative reference when referring to it.
The Intel C compiler for Linux does not seem to reject any bad flags or
object files on its link lines. Work around the problem by using a
preprocessor #error directive to ensure that BADFLAG appears in the
build output. This does not really achieve the purpose of the tests but
it allows them to pass.
Double quote executable names that may have spaces in them.
Do not run the new git portions of the test on machines that
have git < version 1.6.5 on them.
The Borland librarian actually creates a BADFLAG.obj when the object is
missing the first time! This causes later tests to not reject it.
Instead use a Borland-specific variation on the flag.
Add archives of these file types and add to the test
cases covered in the ExternalProject test.
Also add an "Example" directory in the Tests/ExternalProject
directory containing the canonical simplest example of
ExternalProject usage.
Add a LinkFlags test series to check that these properties work. Since
no link flag is accepted everywhere we test for presence of flags by
adding a bad flag and looking for the complaint in the test output.
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.
Improve FILE(DOWNLOAD ...):
- Add percent complete progress output to the FILE DOWNLOAD
command. This progress output is off by default to
preserve existing behavior. To turn it on, pass
SHOW_PROGRESS as an argument.
- Add EXPECTED_MD5 argument. Verify that the downloaded
file has the expected md5 sum after download is complete.
- Add documentation for SHOW_PROGRESS and EXPECTED_MD5.
When the destination file exists already and has the
expected md5 sum, then do not bother re-downloading
the file. ("Short circuit" return.)
Also, add a test that checks for the status output
indicating that the short circuit behavior is actually
occurring. Use a binary file for the test so that the
md5 sum is guaranteed to be the same on all platforms
regardless of "shifting text file line ending" issues.
Improve ExternalProject:
- Add argument URL_MD5.
- Add verify step that compares md5 sum of .tar.gz file
before extracting it.
- Add md5 check to download step, too, to prevent
unnecessary downloads.
- Emit a warning message when a file is not verified.
Indicate that the file may be corrupt or that no
checksum was specified.
Add the <Email>...</Email> element in Update.xml for each commit
reported. This field was defined by Dart but never really used.
Distributed version control systems use author name and email
instead of a user id, so now it makes sense to use this field.
Some Mac linkers produce the message
"file was built for unsupported file format which is not the
architecture being linked"
for this test. Update the test output regex to match it.
Git does not automatically checkout the matching version of a submodule
when it checks out a new version of the parent project in the work tree.
If the submodule reference changed in the parent project then we were
reporting the submodule path as a local modification. Work around the
problem in ctest_update using "git submodule update" after "git pull".
For projects with no submodules this is a no-op. See issue #10662.
Also add a submodule to the test project for CTest.UpdateGIT to test the
work-around.
For builds from Git repositories, add "-g<commit>" to the end of the
version number. If the source tree is modified, append "-dirty".
For builds from CVS checkouts, add "-cvs-<branch>".
