The SaveRestoreEnvironment helper object makes sure that the
original environment is restored immediately after the
StartProcess call returns rather than waiting for the end
of the test. When tests are executed in parallel, there is
no guarantee about the ordering of EndTest calls relative
to StartTest calls. In fact, it would be odd for them to
be nested nicely. Therefore, to avoid the corruption of
the calling ctest's environment, the original environment
must be restored before ForkProcess returns.
Allow the user to set the CMake variable CTEST_COST_DATA_FILE, which will be used to store the cost data from test runs. If not set, defaults to the original location in the build tree Testing/Temporary dir.
We use 'git diff-index' to detect local modifications after pull. On
some filesystems the work tree timestamps of a few files may be dated
after the index, making them appear as locally modified. We address the
problem by using 'git update-index --refresh' to refresh the index and
avoid false local modifications.
Our internal path processing methods assume no trailing slashes, but bzr
adds trailing slashes to updated directories. This can lead to empty
entries in Update.xml files. We address the problem by stripping the
slashes as soon as they are parsed.
The improved text gives very clear information when either the CMakeLists.txt or CTestConfig.cmake file is missing. Hopefully, it makes it easier for those poor future souls who encounter these messages to solve their problems quickly.
If APPEND is given to ctest_start, it will read the tag from the current existing Testing/TAG file rather than creating a new one based on the current time stamp. This allows a developer to run several dashboard scripts in a row, all of which will share the same tag/stamp/buildid when they finally get submitted to CDash. Now you can split the running of build phases and test phases for the same dashboard row into multiple scripts.
Previously we produced commit times formatted like
1261403774 -0500
which is what the Git plumbing prints. Now we use a human-readable
format like
2009-12-21 15:28:06 -0500
which is still easy to machine-parse.
Previously we escaped quotes in <UpdateCommand>...</UpdateCommand>
values using '"'. This is not necessary because the value is in
xml CDATA and not an xml attribute.
A Subversion revision is unique across the entire repository, but work
trees typically correspond only to a subdirectory below the root path.
In order to specify the version of the source code that was tested,
CTest now submits a <SVNPath> element in Update.xml that specifies the
directory of the repository that corresponds to the work tree. In
combination with the revision number this uniquely specifies the tested
source. See issue #7541.
We teach CTest to report in a <Revision> element the revision of the
source tree that was tested. This makes sense for all modern VCS tools
because they version the whole tree. We simply omit this element for
CVS because it only versions files. See issue #7541.
In CTest command-driven script mode we support starting without a source
tree. Previously the ctest_start() command would do some initialization
but could not do anything that required CTestConfig.cmake from the input
source tree. Later, ctest_update() would run CTEST_CHECKOUT_COMMAND to
create the source tree, and then re-initialize everything. This
delayed-initialization approach led to many complicated cases of which
only some worked. For example, the second initialization only worked
correctly in Nightly mode and simply failed for Experimental and
Continuous builds.
A simpler solution is to run CTEST_CHECKOUT_COMMAND during ctest_start()
and then have a single initialization path. In principle this change in
behavior could break scripts that set the checkout command after
ctest_start() but before ctest_update(). However, the convention we've
always followed has been to set all variables before ctest_start().
