#pragma once is a widely supported compiler pragma, even though it is
not part of the C++ standard. Many of the issues keeping #pragma once
from being standardized (distributed filesystems, build farms, hard
links, etc.) do not apply to CMake - it is easy to build CMake on a
single machine. CMake also does not install any header files which can
be consumed by other projects (though cmCPluginAPI.h has been
deliberately omitted from this conversion in case anyone is still using
it.) Finally, #pragma once has been required to build CMake since at
least August 2017 (7f29bbe6 enabled server mode unconditionally, which
had been using #pragma once since September 2016 (b13d3e0d)). The fact
that we now require C++11 filters out old compilers, and it is unlikely
that there is a compiler which supports C++11 but does not support
#pragma once.
The `PROCESSES` test property name added for CMake 3.16 is too close to
the existing `PROCESSORS` test property. Furthermore, the property in
principle specifies groups of resources organized in a way that is
meaningful to a particular test. The groups may often correspond to
processes but they could have other meanings. Since the property name
`PROCESSES` has not been in a final 3.16 release yet, simply rename it
to `RESOURCE_GROUPS`.

Exit code constants on Windows, such as `STATUS_NO_MEMORY` do not fit in
a 32-bit signed integer type. They do fit in an unsigned 32-bit type,
but for compatibility with UNIX semantics we treat exit codes as signed.
Use a 64-bit signed integer to handle both.
- Number of passed/failed tests is colored according to the whole outcome
- Individual listed tested are colored according to their completion status:
* Disabled: blue
* Failed: red
* Not Run: yellow
In commit v2.8.0~170 (ENH: Added ctest test options PROCESSORS and
RUN_SERIAL, 2009-09-07) CTest learned to track the number of processors
allocated to running tests in order to balance it against the desired
level of parallelism. Extend this idea by introducing a new
`PROCESSOR_AFFINITY` test property to ask that CTest run a test
with the CPU affinity mask set. This will allow a set of tests
that are running concurrently to use disjoint CPU resources.
This commit introduces cmDuration as a typedef for
std::chrono::duration<double, std::ratio<1>>. It is less verbose and
provides for a point to put future common functionality for durations.
No functional change intended.
This commit continues the refactoring of CTest to adopt std::chrono.
After the last sets of changes that introduced std::chrono::steady_clock
and std::chrono::system_clock respectively, it makes sense to have all
the timeouts be stored as std::chrono::duration.
No functional change intended.
After the refactor to make CTest use std::chrono::steady_clock for the
keeping of time for test duration, there are still references to
cmSystemTools::GetTime() left.
To further adopt std::chrono for time related activities, this commit
changes those remaining references to std::chrono::system_clock::now()
calls and alters the storage from either unsigned int or double to
std::chrono::system_clock::time_point.
For ease of conversion, a converter method is added to cmXMLWriter that
converts from a std::chrono::system_clock::time_point to the number of
seconds since the UN*X epoch as that is expected behaviour. This means
no more casts as required.
Functionally should be no difference as the system_clock is implemented
in the same terms.
It was reported in issue #17345 that CTest does not use monotonic time
to report test duration. Monotonic clocks are not affected by large NTP
adjustments or things like daylight savings time.
As CMake 3.10 requires C++11, which introduced std::chrono, this commit
moves the time keeping in CTest from cmSystemTools::GetTime() to
std::chrono::steady_clock.

We now require C++11 support including `override`. Drop use of
the old compatibility macro. Convert references as follows:
git grep -l CM_OVERRIDE -- '*.h' '*.hxx' '*.cxx' |
xargs sed -i 's/CM_OVERRIDE/override/g'
This commit splits out the reporting of labels and labels used for sub
projects. If a label is a sub project label it will not be included in
the label summary. To implement this the commit creates
PrintLabelOrSubprojectSummary which is able to do the work of both
PrintLabelSummary and PrintSubprojectSummary avoiding code duplication.
When this property is set, the test is skipped and its status is
automatically set to 'Not Run'. A disabled test will not be counted in
the total number of tests and its completion status will be 'Disabled'.
Per-source copyright/license notice headers that spell out copyright holder
names and years are hard to maintain and often out-of-date or plain wrong.
Precise contributor information is already maintained automatically by the
version control tool. Ultimately it is the receiver of a file who is
responsible for determining its licensing status, and per-source notices are
merely a convenience. Therefore it is simpler and more accurate for
each source to have a generic notice of the license name and references to
more detailed information on copyright holders and full license terms.
Our `Copyright.txt` file now contains a list of Contributors whose names
appeared source-level copyright notices. It also references version control
history for more precise information. Therefore we no longer need to spell
out the list of Contributors in each source file notice.
Replace CMake per-source copyright/license notice headers with a short
description of the license and links to `Copyright.txt` and online information
available from "https://cmake.org/licensing". The online URL also handles
cases of modules being copied out of our source into other projects, so we
can drop our notices about replacing links with full license text.
Run the `Utilities/Scripts/filter-notices.bash` script to perform the majority
of the replacements mechanically. Manually fix up shebang lines and trailing
newlines in a few files. Manually update the notices in a few files that the
script does not handle.
Add new test properties:
* FIXTURES_SETUP
* FIXTURES_CLEANUP
* FIXTURES_REQUIRED
to specify the roles and dependencies of tests providing/using
test fixtures.
Run the `Utilities/Scripts/clang-format.bash` script to update
all our C++ code to a new style defined by `.clang-format`.
Use `clang-format` version 3.8.

Add ctest command-line options:
--test-output-size-passed <n>
--test-output-size-failed <n>
to set the amount of test output to store in Test.xml as a command-line
dashboard client.
