This replaces `std::ostringstream`, when it is written to only once.
If the single written argument was numeric, `std::to_string` is used instead.
Otherwise, the single written argument is used directly instead of the
`std::ostringstream::str()` invocation.
Sanitizers do not create a log file when no defects are found. Therefore,
it is currently impossible for ctest_memcheck to set both
`CAPTURE_CMAKE_ERROR` and `RETURN_VALUE` to zero.
With defects, `CAPTURE_CMAKE_ERROR`=0 and `RETURN_VALUE`=-1, as expected.
With no defects, `CAPTURE_CMAKE_ERROR`=-1 and `RETURN_VALUE`=0.

* Change some functions to take `std::string` instead of
`const char*` in the following classes: `cmMakeFile`, `cmake`,
`cmCoreTryCompile`, `cmSystemTools`, `cmState`, `cmLocalGenerator`
and a few others.
* Greatly reduce using of `const char*` overloads for
`cmSystemTools::MakeDirectory` and `cmSystemTools::RelativePath`.
* Remove many redundant `c_str()` conversions throughout the code.
A problem area by recent refactoring of time to std::chrono has been the
unsafe conversion from duration<double> to std::chrono::seconds, which
is of an unspecified integer type.
This commit adds a template function that for a given type provides a
safe conversion, effectively clamping a duration<double> into what fits
safely in that type. A specialisation for int and unsigned int are
provided.
It changes the protential problem areas to use this safe function.
IWYU incorrectly classifies this internal STL type as not internal, and
suggests including `<type_traits>` for it. Work around the problem by
mapping the offending names to a file that we always include.
See include-what-you-use issue 434.
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'
This check was not functioning properly for the following reasons:
* The "DropSite" and "DropLocation" CTest Configurations do not
get set until ctest_submit() is called. So if ctest_submit()
was not called before ctest_test() we would end up with uncompressed
output, even if the CDash server was new enough to support this feature.
* CDash's API is now versioned. The current location to query is
now /api/v1/getversion.php, not /api/getversion.php.
As a result of these issues, CTest would not compress test/memcheck
output when it should. Rather than fix this check, we now assume that
CTest is communicating with a new enough version of CDash. This behavior
can be controlled through the use of the --no-compress-output command-line
argument.
Apply the change from commit bd3d0eaf (cmCTest: don't redefine cout and
cerr, 2016-09-01) to the rest of ctest and cpack. These definitions
are no longer needed because our conventions are well established.
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 clang-tidy's modernize-use-override checker. This checker must have
issues in version 3.8. It has way too little matches. And it adds
override to destructors. Revert the changes on the destructors and
change override to CM_OVERRIDE.
Use clang-tidy's readability-simplify-boolean-expr checker.
After applying the fix-its, revise all changes *very* carefully.
Be aware of false positives and invalid changes.
