The allows `-E create_symlink` to work on Windows. It utilizes
`uv_fs_symlink`. I am still unsure exactly which Windows platforms will
work without requiring Administrator privileges or needing a user/group
with the "Create Symbolic Links" User Rights. It does work with my
Windows 10 Pro with Developer Mode turned on. In the test suite check
that the symlink either worked or failed with a permissions error.
Use recent changes in cmSystemTools::FileExists to check that a symlink
is broken.
Document the previously internal option of '-B' and provide a
matching source directory option with '-S'. Both '-B', and '-S'
can be used independently of each other.
While we already support `cmake --build . -- -j`, the options after `--`
are specific to the native build tool. Add new options `--parallel
[<N>]` and `-j [<N>]` to abstract this and map to the proper option
for the native build tool.
Some code paths in `ExpandVariablesInString{New,Old}` were not checking
the `filename` parameter for a null pointer, but this can happen when
using the above flags together. Add the checks and a test case.
Fixes: #17896
This commit changes the internal -E__run_iwyu to be -E__run_co_compile. This
is used for co-compile commands. These are tools that want to mirror the
compiler. For each compiler invocation the tool will be invoked first. This
started as a way to implement include what you use (iwyu), but has expanded
to include cpplint, cppcheck and others. Likely there will be more in the
future as well. This commit implements each one in its own function and
provides a way to add additional ones in the future with less work.
Use it to split pipe and stdin/out handling out of cmServer itself.
The server will shut down when it looses its connection to the client.
This has the nice property that a crashing client will cause the server
to terminate as the OS will close the connection on behave of the client.
Adds a bare-bones cmake-server implementation and makes it possible
to start that with "cmake -E server".
Communication happens via stdin/stdout for now.
Protocol is based on Json objects surrounded by magic strings
("[== CMake Server ==[" and "]== CMake Server ==]"), which simplifies
Json parsing significantly.
This patch also defines an interface used to implement different
versions of the protocol spoken by the server, but does not include
any protocol implementaiton.
Even in relatively small projects using `--trace` (and `--trace-expand`)
may produce a lot of output. When developing a custom module usually
one is interested in output of only a few particular modules.
Add a `--trace-source=<file>` option to enable tracing only a subset of
source files. The final output would be only from requested modules,
ignoring anything else not matched to given filename(s).
Previously we did not clearly document that `--target` is only supported
to be specified once. Even worse, specifying it multiple times would
silently ignore any previously specified targets and only build the last
target.
Update the documentation to specify this. Update the implementation to
reject multiple `--target` options to prevent user errors.
Since this command was introduced in 2002 it has incorrectly constructed
the child process command line by concatenating arguments separated by
spaces with no quoting. Fix this by passing the command argument vector
directly to RunSingleCommand without an intermediate quoting and
re-parsing step.

Expand the -W set of cmake options to include support for the -Werror
and -Wno-error format, which is used to control upgrading and
downgrading warning and error messages. Implement support for these new
formats for the dev and deprecated message types.
Add tests and updated documentation for new options.
If multiple input files are provided then the destination must be a
directory. If only one input file is provided then destination may be
either a file or directory.
Explicitly enable deprecated warnings by default, via the
cmake::GetSuppressDeprecatedWarnings method, which signals
suppression is turned off unless the CMake variables are set
as required.
Add tests and update the documentation for the new
functionality.
Change the '-Wdev' and '-Wno-dev' options to also enable and
suppress the deprecated warnings output, via the
'CMAKE_WARN_DEPRECATED' CMake variable, by default. This
action does not happen if the user specifies a deprecated
warning message option.
Add tests and update the documentation for the new
functionality.
Add 'deprecated' warning options type, to allow setting
CMAKE_WARN_DEPRECATED via the -W '-Wdeprecated' and
'-Wno-deprecated' options.
Add tests for new options and updated documentation.
Refactor the -Wdev and -Wno-dev options parser to use a generic -W
parser that follows the GCC pattern, excluding support for
-Werror=TYPE and -Wno-error=TYPE formats for now.
Explicitly enable author warnings by default, via the
cmake::GetSuppressDevWarnings method, which signals suppression
is turned off unless the CMake variables are set as required.
Add test cases for author and deprecated messages displayed by
default.
The changes in commit c96fe0b4 (cmake: Add -W options to control
deprecation warnings and errors, 2015-07-28) fail to account for
-Wdev warnings produced by places in CMake other than message().
This causes a regression in which -Wno-dev fails to suppress such
warnings. Revert the feature until it can be revised accordingly.
Refactor the -Wdev and -Wno-dev to use a generic -W parser that follows
the GCC pattern. Include support for setting CMAKE_ERROR_DEPRECATED and
CMAKE_WARN_DEPRECATED via the deprecated warning. Add -Werror=dev and
-Wno-error=dev options so that dev warning options are in line with
deprecated warning options. Use a new CMAKE_SUPPRESS_DEVELOPER_ERRORS
internal cache entry to store the above new dev options persistently.
Add tests for new options and updated cmake documentation and release
notes to list new options.
The --trace option is helpful, but sometimes, what you're looking for is
deep under many layers of function calls and figuring out what instance
of the function call you're looking at is tedious to determine (usually
involving patching and message()). Instead, add a --trace-expand option
to trace while expanding commands into what CMake actually sees.
The VS >= 10 generators need to parse the .sln file from the build
directory to locate targets in subdirectories. This occurs after we
change the working directory to the build tree. If a relative directory
other than "." was given then we would change to it and also refer to
the .sln file location with it. Fix this by converting the build tree
to a full path always. This will also give a more informative error
message when the directory does not exist.
Add an internal "cmake -E __run_iwyu" mode to wrap the compiler call.
Run a given include-what-you-use command line with the compiler options
and report a warning if it finds anything. Then run the real compiler.

Port most CMakeTestBadCommandLines test cases to RunCMake.CommandLine
and drop the former test. Add validation of expected results, which was
not done by the old test.
Otherwise an #include directive on the first line of a source file is
ignored if the file contains a Byte-Order-Mark.

Read file names from the lines of a specified file. Reject input lines
starting in '-' to leave room for option parsing to be added later. Add
just '--add-file=' now to allow files starting in '-' to be specified.
Add an option to set the mtime of entries in a tarball so that one can
create a tarball with a consistent content hash (e.g. MD5) for a given
set of files regardless of their current timestamps on disk. This will
be useful for submission of tarballs to CDash, which tracks content
hashes to avoid duplication.

Expect tests to specify stderr content if it is present.
Fix the CMP0019 test, which has only been testing the WARN status
until now. Specify in the CommandLine and FPHSA tests that content
is at least one character.
Set policies in the Language and CheckModules tests, which have empty
test output, modulo unrelated policies on some platforms.
