a7319cf ctest_update: Run 'git submodule' at top level
7bf8dc1 ctest_update: Support ".git file" work trees
65cb72f ctest_update: Abort if Git FETCH_HEAD has no candidates
The git submodule porcelain must be executed from the top level of the
work tree. Use 'git rev-parse --show-cdup' to find the top level
relative to the source tree. This is better than searching up the tree
for .git ourselves because it will always work the same way Git does and
thus honors settings like GIT_DISCOVERY_ACROSS_FILESYSTEM.
Commit c3781efb (Support Git upstream branch rewrites, 2010-06-08)
assumed that ".git/FETCH_HEAD" exists inside the source tree. Fix the
implementation to handle a work tree using a ".git file" to link to its
repository. Use "git rev-parse --git-dir" to locate the real .git dir.
If .git/FETCH_HEAD provides no merge candidate do not attempt to update.
Also log FETCH_HEAD lines as we parse them since they are essentially
output from the git fetch command.

e525649 Checksums on CTest submit files, and retry timed out submissions.
Previously, we were only going into the retry block
for time out conditions. But a "could not connect"
response, or really any sort of curl failure, is
also a condition where we should retry the submit
if the user has requested a retry.
Fix niggly in ExternalProject that would inadvertently
create a log file of output when a command was explicitly
set to the empty string.
Also, increase the default value for showing context
around build errors to 10 lines, up from 6. Also add
the ability to customize this setting so that users
can put it back to 6 or even lower if they want, or
show more if they want.
Change types of local variables, or casting, or re-arrange
expressions to get rid of "conversion may alter value" warnings
as seen on recent dashboard submissions from londinium.kitware.
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.
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.
Commit 67277bac (Teach ctest_update about Git submodules, 2010-05-04)
accidentally logged "git submodule update" with the prefixes "pull-out"
and "pull-err". Fix it to use "submodule-out" and "submodule-err"
instead.
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.
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.
Report in <UpdateReturnStatus> when the update command line returns
non-zero. Otherwise the failure may be silently ignored since the error
was previously recorded only in the local log file.
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.
