Apply necessary manual updates to tests to account for changes made by
the introduction of the new diagnostic system. These mainly take three
forms. First, expected output changes that were not caught by the
automated changes made by the previous commit. Second, deprecation
warnings from -Wno-dev which are remedied by replacing uses thereof with
the new -Wno-author form. Third, manipulations of diagnostic state via
the old variables, which are replaced with use of the `cmake_diagnostic`
command.
We have not yet implemented backwards compatibility for the deprecated
`CMAKE_{WARN,ERROR}_DEPRECATED` variables. Once that is done, some of
the tests in the third category will likely reappear in some form.
Update expected test output to account for the new format of diagnostic
messages. These changes were applied entirely by `sed` using the
following commands:
- `/Use -Wno-dev to suppress/s/-Wno-dev/-Wno-author/g`
- `s/Warning [\\][(]dev[\\][)]/Warning \\(author\\)/g`
- `s/CMake Deprecation Warning/CMake Warning \\(deprecated\\)/g`
This is not a complete fix, but covers a significant fraction of the
needed changes, and this commit is strictly automated changes.

Add an additional state to the cmake instance to track diagnostics. Use
this to initialize any new/reset states we create so that other contexts
will inherit the diagnostic state from presets / command-line options.
Modify the front-end to map presets and -W command-line options to
manipulation of this new diagnostic state. Remove old members for
storing diagnostic state. Rework how diagnostic state is persisted.
Deprecate old, non-standard spellings for manipulating diagnostics.
Deprecate old 'dev' spelling for CMD_AUTHOR.
Note that this is a work in progress. Messaging has not yet been
updated, so the new state is not yet being used to control diagnostics,
and some of the logic to update the old state has been stripped (and
will eventually be removed entirely). Backward compatibility support for
the deprecated CMAKE_{WARN,ERROR}_DEPRECATED variables is only partially
implemented. The GUI's interface for manipulating warnings is partially
broken and needs to be overhauled. These tasks are being done in
separate commits in order to minimize review burden and keep the changes
per commit / per merge request more manageable.
This was missed in commit ee83165923 (cmake: Explicitly normalize
input paths as they exist on disk, 2024-10-17, v4.0.0-rc1~597^2),
causing `CMAKE_CURRENT_LIST_FILE` in `cmake -P` scripts to be
regressed by the KWSys behavior change merged by commit e9bd437a43
(Merge branch 'upstream-KWSys' into normalize-input-paths,
2024-10-24, v4.0.0-rc1~589^2~1).
Issue: #27750
Commit 28f2d750ed (Add -Werror and -Wno-error command-line options,
2015-12-21, v3.5.0-rc1~61^2~1) added -W[no-]error along with tests, but
wrote the wrong name in the RunCMakeTest.cmake that actually runs the
test. As a result, the -Wno-error=dev test has never actually run, and
in fact the expected output had an incorrect line number. Fix the
expected output, and fix the RunCMakeTest.cmake to actually run the
test.
Revise the test from commit 01f92efeb0 (Restore expansion of leading '~'
as home directory in input paths, 2025-04-02, v4.0.1~12^2) to tolerate
`~` in the path to CMake's source or build tree. If tilde `~` shell
expansion fails it can only occur at the beginning of a path component.
Enhance `cmake --trace` (and related modes) by adding a backtrace for
the "end" command after "replaying" control structures.
Expand the unit test to include control structures.

Compiler arguments coming from CC environment variables or multi-element
CMAKE_<LANG>_COMPILER variables set by toolchain files were previously not
exposed in the file API. Among other possible problems, this caused clients
to determine wrong system include paths and built-in preprocessor macros by
calling the compiler without these important arguments.
This is fixed by adding an optional "commandFragment" attribute to the
compiler description in the `toolchains` object, containing these arguments
as a command line fragment. This is already the form in which they are
internally stored in the CMAKE_<LANG>_COMPILER_ARG1 variable, so all that is
required is adding this variable to the set of exported variables, besides
some logic to omit it if empty.
Issue: #22568
Print the system error message in case of failure when calling
`CopyFileAlways`, `CopyFileIfDifferent`, `CopyFileIfNewer`,
`CopyADirectory` and `MakeDirectory`.
Remove unnecessary `cmSystemTools` wrappers for `CopyFileIfNewer` and
`CopyADirectory`.
Fixes: #18276
Read the BOM sequentially and store the read bytes for later use if
these do not correspond to a BOM. This allows FIFO to be used as input,
e.g., for piping input or Bash process substitution.
This will allow JSON schemas for these two types of files to describe the
version-specific content without requiring any outside information.
Fixes: #27031
POSIX specifies that two leading slashes have implementation-defined
interpretation, so CMake 3.31 and below did not normalize away leading
double slashes. However, most implementations simply treat a leading
`//` as just `/`, so CMake 4.0 now normalizes them away when they do not
correspond to a network path on Windows.
This change exposed that we were not normalizing `CMAKE_TOOLCHAIN_FILE`
before passing its value to `include()` the first time if it was not
passed with the `FILEPATH` or `PATH` cache entry type. Fix that.
Fixes: #27010
In commit 5aed3ee49d (cmSystemTools: Add GetLogicalWorkingDirectory,
2024-10-28, v4.0.0-rc1~528^2~6) we incorrectly trusted `PWD` to be a
normalized path so long as its realpath matches the current working
directory.
Fixes: #26870
This was accidentally dropped by commit 622596c6b2 (cmSystemTools:
Re-implement ToNormalizedPathOnDisk without translation map, 2024-10-30,
v4.0.0-rc1~528^2~5). Previously it was done by `CollapseFullPath`.
`cm::PathResolver` intentionally does not expand `~` because it makes
sense only for transforming input paths. Teach `ToNormalizedPathOnDisk`
to handle it directly.
