In order to keep infinitely-recursive scripts from causing a stack
overflow in the CMake executable, CMake now imposes a maximum
recursion limit before issuing an error message. The limit can be
adjusted at runtime with CMAKE_MAXIMUM_RECURSION_DEPTH.
Fixes: #18694
This is to avoid scope issues with CTEST_RUN_CURRENT_SCRIPT. If
ctest_start() is called within a function scope, the value of
CTEST_RUN_CURRENT_SCRIPT that it sets doesn't make it to the global
scope. With this change, ctest_start() no longer sets
CTEST_RUN_CURRENT_SCRIPT, and instead sets a field directly in
cmCTestScriptHandler. The old behavior of CTEST_RUN_CURRENT_SCRIPT
has also been kept for projects and tests that rely on setting it.
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.
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.
Fixes: #17345
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'
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names and years are hard to maintain and often out-of-date or plain wrong.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.
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.

Casts from std::string -> cmStdString were high on the list of things
taking up time. Avoid such implicit casts across function calls by just
using std::string everywhere.
The comment that the symbol name is too long is no longer relevant since
modern debuggers alias the templates anyways and the size is a
non-issue since the underlying methods are generated since it's
inherited.
Make sure that CMakeCache.txt is the last file being removed since
the binary directory may be left in a state that is no longer
removable otherwise.
Also retry removal a couple of times which makes this more robust
on windows where file locks may temporarily prevent removal.
We will no longer support full documentation generation from executables
and will instead generate documentation with other tools. Disable (with
a warning left behind) the command-line options:
--copyright
--help-compatcommands
--help-full
--help-html
--help-man
Drop supporting code. Drop manual sections generation from executables.
Remove internal documentation construction APIs. Drop unused sections

This converts the CMake license to a pure 3-clause OSI-approved BSD
License. We drop the previous license clause requiring modified
versions to be plainly marked. We also update the CMake copyright to
cover the full development time range.
