The ownership semantics of the 'testRun' variable are subtle and
may fool static analysers. Add comments explaining them for now.
Later some refactoring could be done to clarify the code.
Issue: #19610
This adds the following functions to cmStringAlgorithms:
- `cmStrToLong`: moved from `cmSystemTools::StringToLong`
- `cmStrToULong`: moved from `cmSystemTools::StringToULong`
Overloads of the given functions for `std::string` are added as well.
An old workaround for `std::allocator_traits<>::value_type` lints from
IWYU on `std::vector<>` usage breaks IWYU's handling of `<memory>`.
Convert the workaround to use the same approach we already use for a
workaround of `std::__decay_and_strip<>::::__type` lints. Then update
the `<memory>` inclusions to follow the now-correct IWYU lints.
Suppress some cases in `Source/cmGeneratorExpressionNode.cxx` and
`Source/cmUVHandlePtr.h` where a few older compilers require a
user-defined default constructor (with `{}`).
Avoid exposing the internal special value that we use to track tests not
available in the tested configuration. This also prevents clients from
having to do the filtering themselves.
format can be 'human' to print the current text format or 'json-v1' to
print the test object model in json format and is useful for IDEs who
want to gather information about the tests. Defaults to 'human' format.
The CTestTestStopTime test has been failing sporadically because the
stop time causes the first internal test to have a timeout short enough
that we might hit it and start the second test just before the stop time
is reached. Instead we should track when a timeout is shortened in
order to stay within the stop time. If a test times out for this reason
then we should consider the stop time reached and not start any more
tests.
The `ctest --test-load` option is implemented in `StartNextTests` by not
starting any tests when the load is too high and instead sleeping and
then returning. Prior to commit v3.11.0-rc1~117^2 (CTest: Re-implement
test process handling using libuv, 2017-12-10) our outer loop in
`RunTests` would immediately call `StartNextTests` again. However, now
the `uv_run` loop may simply terminate if there are no tests running
because no events are left pending.
Fix this by converting the sleep in `StartNextTests` into a libuv timer
that it starts instead. This avoids leaving `uv_run` with no pending
events. In the case that there are other running tests this also allows
CTest to detect when they finish even if it during the wait period where
we previously slept.
This regression was not caught by the test suite because it only
verified that we do not start new tests when the load was too high and
not that we proceed to start tests when the load drops. Revise the test
suite to cover both.

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.
* 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.
Prior to 1.19, libuv does not use SA_RESTART in its signal handler.
Add a helper to cause libuv to install its handler and then revise
the handler's flags to add SA_RESTART.
If `StartTestProcess` does not start a test, propagate this information
back up to the `StartNextTests` loop so that it can move on to another
candidate without allocating processors to a test that didn't run.
Otherwise we have to wait for the next time `RunTests` loops around and
calls `StartNextTests` again.
Avoid creating a cmCTestRunTest instance if the stop time has been
reached. If the stop time occurs in the small time between creating an
instance and computing the child process timeout, we will simply compute
a zero timeout. This is already done for the case that we StartAgain
after the stop time.
As reported in issue 17167, when only RUN_SERIAL tests remain, CTest can
display a misleading message that it is waiting for the load to come
down when in fact, it cannot start any new tests.
This commit fixes that by determining whether this circumstance is
what's happening and adds an additional warning message in this case.
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'.
These functions just need to change the directory for a block of code
and then go back to the caller's expected location. Use
cmWorkingDirectory to ensure that all return paths are handled.
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.
