is not used for anything else afterwards.

Provide a standardized way to handle the C++ "standard" headers
customized to be used with current CMake C++ standard constraints.
Offer under directory `cm` headers which can be used as direct
replacements of the standard ones. For example:
#include <cm/string_view>
can be used safely for CMake development in place of the `<string_view>`
standard header.

This replaces the code pattern
```
std::vector<std::string> args;
cmExpandList(valueStr, args, ...)
```
with
```
std::vector<std::string> args = cmExpandedList(valueStr, ...)

This patch is generated by a python script that uses regular expressions to
search for string concatenation patterns of the kind
```
std::string str = <ARG0>;
str += <ARG1>;
str += <ARG2>;
...
```
and replaces them with a single `cmStrCat` call
```
std::string str = cmStrCat(<ARG0>, <ARG1>, <ARG2>, ...);
```
If any `<ARGX>` is itself a concatenated string of the kind
```
a + b + c + ...;
```
then `<ARGX>` is split into multiple arguments for the `cmStrCat` call.
If there's a sequence of literals in the `<ARGX>`, then all literals in the
sequence are concatenated and merged into a single literal argument for
the `cmStrCat` call.
Single character strings are converted to single char arguments for
the `cmStrCat` call.
`std::to_string(...)` wrappings are removed from `cmStrCat` arguments,
because it supports numeric types as well as string types.
`arg.substr(x)` arguments to `cmStrCat` are replaced with
`cm::string_view(arg).substr(x)`

This changes `cmMakefile::AddDefinition` to take a `cm::string_view` as value
argument instead of a `const char *`.
Benefits are:
- `std::string` can be passed to `cmMakefile::AddDefinition` directly without
the `c_str()` plus string length recomputation fallback.
- Lengths of literals passed to `cmMakefile::AddDefinition` can be computed at
compile time.
In various sources uses of `cmMakefile::AddDefinition` are adapted to avoid
`std::string::c_str` calls and the `std::string` is passed directly.
Uses of `cmMakefile::AddDefinition`, where a `nullptr` `const char*` might
be passed to `cmMakefile::AddDefinition` are extended with `nullptr` checks.
|
|
|
|
|
|
|
| |
This simplifies the `cmMakefile::AddDefinition` method with bool value
overload to call the string based `cmMakefile::AddDefinition` method
with either an "ON" or "OFF" string.
Also the method is renamed to `cmMakefile::AddDefinitionBool`

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.

After changing the ``cmGeneratedFileStream`` methods to accept
``std::string const&`` instead of ``const char*`` we don't
need to call ``std::string::c_str`` anymore when passing
a ``std::string`` to a ``cmGeneratedFileStream`` method.
This patch removes all redundant ``std::string::c_str``
calls when passing a string to a ``cmGeneratedFileStream`` method.
It was generated by building CMake with clang-tidy enabled using
the following options:
-DCMAKE_CXX_CLANG_TIDY=/usr/bin/clang-tidy-4.0;-checks=-*,readability-redundant-string-cstr;-fix;-fix-errors

* 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.

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 continues the changes made in CTest to support std::chrono

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.

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.

Refactoring in commit 66419bc046 (CTest: convert timeouts to
std::chrono::duration, 2017-11-20) changed out "infinite" timeout to a
value not representable by a 64-bit integer. This causes undefined
behavior when e.g. KWSys Process converts the duration to a `long` to
interact with system APIs. Use the old `1.0e7` maximum value.

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.

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.

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
