This reverts commit v3.7.0-rc1~275^2 (Ninja: Use full path for all
source files, 2016-08-05). Unfortunately using absolute paths can
cause incorrect rebuilds due to ninja limitations. The ninja
manual [1] explains:
> ... using absolute paths, your depfile may result in a mixture of
> relative and absolute paths. Paths used by other build rules need
> to match exactly.
Passing an absolute path to a source file to the compiler while using a
relative path in the ninja build manifest can cause such mixture and
lead to incorrect rebuilds. Simply revert the change for now.
Note that there was a follow-up to the original change in commit
v3.7.0-rc2~10^2 (Ninja: Fix RC language depfile generation with
cmcldeps, 2016-10-13). We don't need to revert that because that
change made the relevant code cleverly adapt to whatever variable
we use to reference the source file.

Issue: #13894
Create a `<LANG>_CPPLINT` target property (initialized by a
`CMAKE_<LANG>_CPPLINT` variable) to specify a `cpplint` style checker
command line to be run along with the compiler.
Call sites of `ExpandRuleVariables` are now responsible for inserting
the `RULE_LAUNCH_{COMPILE,LINK,CUSTOM}` values in rule command lines.
Audit all call sites and add a comment to each one that does not insert
a launcher to explain why.
Change the default compile PDB file name for static libraries to match
the Visual Studio default of using the logical target name. This may be
incompatible with existing behavior but `COMPILE_PDB_NAME` documents
that the default is unspecified. Projects depending on a particular
name should set the property.
Closes: #16438
This allows users to specify different genex-based compile flags for
each file in a target, e.g. compiling just a single file with `Od/Ox` in
release builds on Visual Studio.
Add a factory function to cmLocalGenerator so that variableMappings can
be provided from it, and so that Ninja can always have a hard-coded
TargetImpLib.
The rule replacement API should not really be in cmLocalGenerator, but
it was historically, and this coupled many other things together here
too, such as output conversion. Make the output converter a parameter
so that rule replacement can be removed from cmLocalGenerator.
This one is not like the others as it doesn't participate in
substitutions. Keep ExpandRuleVariables doing only one thing and make
callers responsible for inserting a launcher prefix, simplifying the
code all-around.
Remove now-obsolete InsertRuleLauncher method.
In commit v3.7.0-rc1~275^2 (Ninja: Use full path for all source files,
2016-08-05), the source path was changed to use an absolute path.
Inside of `cmcldeps` for `.rc` file compilation, it uses a separate
argument for the path to the source file. This ended up causing
`cmcldeps` to transform the following call:
cmcldeps.exe RC source.rc ... C:/full/path/to/source.rc
into:
... C:/full/path/to//Tc source.rc
which is invalid. Update the source filename to use the full path to
the source file so that the path is replaced properly.
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.
Fortran INCLUDE statements are not handled by the preprocessor.
Since the location of the preprocessed file is distinct from the
original source file explicitly add the source file's directory
as an include path in the actual compile step (not the preprocessing step)
so INCLUDE can find it.
Closes: #16332
All Fortran sources need to be preprocessed before any source may be
compiled so that module dependencies can be (later) extracted. Factor
out an explicit preprocessing step preceding compilation. Use Ninja
depfile dependencies on the preprocessing step and then compile the
already-preprocessed source with a separate build statement that depends
explicitly only on the preprocessor output. Later we will insert
dynamic discovery of module dependencies between these steps.
Ninja 1.7 introduced support for implicit outputs on build statements.
Teach WriteBuild to generate the corresponding syntax. Leave it up to
callers to decide whether implicit outputs are supported by the Ninja
version in use. For now simply update all call sites to pass an empty
list of implicit outputs.
With the Makefile generator one can use `cd $subdir; make install` to build and
install targets associated with a given subdirectory. This is not possible to
do with the Ninja generator since there is only one `build.ninja` file at the
top of the build tree. However, we can approximate it by allowing one to run
`ninja $subdir/install` at the top of the tree to build the targets in the
corresponding subdirectory and install them.
This also makes sense for `test`, `package`, and other GLOBAL_TARGET targets.
It was already done for `all` by commit v3.6.0-rc1~240^2~2 (Ninja: Add
`$subdir/all` targets, 2016-03-11).

In commit v3.6.0-rc1~174^2 (Ninja: Honor CMAKE_NINJA_FORCE_RESPONSE_FILE
for compile rules, 2016-04-06), Ninja learned to look for
`CMAKE_NINJA_FORCE_RESPONSE_FILE` in the current scope or the
environment in order to force response file usage for all compilation
rules.
However, on Windows, the RC compiler goes through cmcldeps which does a
`replace(output, output + ".dep.obj")` on the command line. However,
with a response file (which we name `output + ".rsp"`), the response
file path is replaced instead causing the compiler to (correctly)
complain that the response file `output + ".dep.obj.rsp"` does not
exist.
What needs to happen is for cmcldeps to look through the response file,
replace *its* contents and place it in the `output + ".dep.obj.rsp"`
file.
Also add a test which actually compiles an RC file into a library and
executable for all generators on Windows and additionally test
`CMAKE_NINJA_FORCE_RESPONSE_FILE` for Ninja generators.

Sort include directives within each block (separated by a blank line) in
lexicographic order (except to prioritize `sys/types.h` first). First
run `clang-format` with the config file:
---
SortIncludes: false
...
Commit the result temporarily. Then run `clang-format` again with:
---
SortIncludes: true
IncludeCategories:
- Regex: 'sys/types.h'
Priority: -1
...
Commit the result temporarily. Start a new branch and cherry-pick the
second commit. Manually resolve conflicts to preserve indentation of
re-ordered includes. This cleans up the include ordering without
changing any other style.
Use the following command to run `clang-format`:
$ git ls-files -z -- \
'*.c' '*.cc' '*.cpp' '*.cxx' '*.h' '*.hh' '*.hpp' '*.hxx' |
egrep -z -v '(Lexer|Parser|ParserHelper)\.' |
egrep -z -v '^Source/cm_sha2' |
egrep -z -v '^Source/(kwsys|CursesDialog/form)/' |
egrep -z -v '^Utilities/(KW|cm).*/' |
egrep -z -v '^Tests/Module/GenerateExportHeader' |
egrep -z -v '^Tests/RunCMake/CommandLine/cmake_depends/test_UTF-16LE.h' |
xargs -0 clang-format -i
This selects source files that do not come from a third-party.
