Brad King 7f2dc8dc54 configure_file: Test that CMake re-runs on input change or output missing
With the Makefile generators we expect that touching or modifying the
input file of a configure_file, or removing its output, will cause CMake
to re-run on the next build.  Extend the RunCMake.configure_file test
with a case covering this.  Also check that CMake does not re-run if
nothing has changed.

have a server then the drop might actually appear to work.  Instead use
an explicit '-no-site-' host to ensure it cannot connect.

Stephen Kelly 23f3798c7b cmTarget: Compute link language of TARGET_OBJECTS with CMP0026 OLD (#15338)
Commit v3.1.0-rc1~297^2~5 (cmTarget: Drop 'head' argument from
GetSourceFiles, 2014-07-10) exposed a dormant bug in source file computation,
causing the test case to regress.  After that commit, the source file
computation and caching finds an existing container of source files.  Prior to
that patch, the GetSourceFiles method was called with either a null pointer
for the head cmTarget, or it was called with the this pointer.  The
processSources method is eventually called, which normalizes the difference
between the null pointer and the this pointer for the head target.  However,
the cache key depends on the actual pre-normalized pointer.  The change in
that commit caused the entry to be found in the cache where it was not before,
which resulted in incorrect behavior.

Prior to that commit, the test case also fails if the GetSourceFiles overload
taking a vector<cmSourceFile*> is changed to normalize the head target at
the beginning of the method:

  cmTarget const* head = head_ ? head_ : this;

Such a construct was correctly used in other locations where similar caching
was in place, before being removed in commit v3.1.0-rc1~310^2~25 (cmTarget:
Remove 'head' argument from GetLinkInformation, 2014-06-12), but is not
neccessary anymore.

Commit v3.1.0-rc1~674^2~2 (cmTarget: Cache the cmSourceFiles in
GetSourceFiles., 2014-04-05) introduced the caching, but fails the test case
for an unrelated reason.  That unrelated error was introduced in
commit v3.1.0-rc1~688^2~5 (cmTarget: Allow any generator expression in
SOURCES property., 2014-03-18) and fixed in
commit v3.1.0-rc1~561^2~1 (cmTarget: Fix listing of source files at
configure-time., 2014-04-13).

All commits which fail the test case in the testable way do so when such a
cached version of the source files is found and returned at generate
time.  In the test case, the cached content is populated at configure-time
through the use of the deprecated LOCATION property with CMP0026 OLD.  The
cached content is an empty container for the bar target in the test case,
because its source file 'foo.cpp.o' is not known until generate-time.  That
means that no source files are available to compute the link language and
the reported error is issued.

The actual problem is that the SourceFilesMap should be cleared after
configure time by cmTarget::ClearLinkMaps.  Clear it there now.

Robert Maynard f73718c9b8 Features: Enable writing of MSVC compiler feature header.
Notes:
VS2015 and above are the only MSVC versions to support cxx_final, so remove
usages from the tests, and instead only test for cxx_override.

VS2012 and above to conform to cxx_decltype_incomplete_return_types
proposal, but without support for auto return types the dcl.type.simple
example in the proposal doesn't compile.

VS2013 and above to conform to the updated cxx_contextual_conversions proposal,
but VS2010 and above pass the test.

Compilers such as MSVC have no explicit flags to enable C++11 mode,
it just is always on. So only run the link tests with compilers that require
a flag to specify the language version.

2014-12-01 08:57:34 -05:00
Stephen Kelly e134805666 Export: Disallow export of targets with INTERFACE_SOURCES
This can be allowed in the next release, but it needs to have some
features present and tested such as

* Ensuring that relative paths do not appear in the generated property.
* Ensuring that paths to the source or build directories do not appear.
* Generating a check in the file for CMake 3.1 or later so that the
    resulting property will be consumed.
* Ensuring that any referenced targets are part of an export set and
    generating a check for them.
* INSTALL_INTERFACE and BUILD_INTERFACE content.

All of these checks are already done for INTERFACE_INCLUDE_DIRECTORIES,
but it is too late to add them for INTERFACE_SOURCES for CMake 3.1.
As the checks introduce some new error conditions, it is better to
disallow exporting fully for this case and introduce proper error
conditions later instead of policies.
2014-11-29 12:24:59 +01:00
Stephen Kelly bb5905bb13 cmTarget: Don't allow relative paths in INTERFACE_SOURCES
Follow the pattern of checks that are made for INTERFACE_INCLUDE_DIRECTORIES.
Existence is already checked by cmSourceFile::GetFullPath.  Add a check
to disallow relative paths in source directories. Otherwise code such as

 target_sources(lib1 INTERFACE foo.cpp)

would fail if consumed by a target in a different directory.

Unlike the INTERFACE_INCLUDE_DIRECTORIES behavior, we don't care whether
the entry comes from an IMPORTED target or not.  In the include directories
case, the directory for a non-imported target might not exist yet but
might be created.  In the sources case, a file which does not yet
exist in the filesystem must be explicitly marked with the GENERATED
property.

Adjust existing tests and add a new test for the error.

Stephen Kelly 26e98c34dc file(GENERATE): Re-run cmake when appropriate.
Re-run if the input file changes or if the output file is removed.

This only works with the Makefile generators currently.  The limitation
of the Ninja generator is tracked as issue #15256.  The IDE
generators will need larger refactoring as they currently rely on
being able to determine the depends and output files at the start of
generate-time, which is too early for the file(GENERATE) case.

Brad King e15a7075b5 Add an option for explicit BYPRODUCTS of custom commands (#14963)
A common idiom in CMake-based build systems is to have custom commands
that generate files not listed explicitly as outputs so that these
files do not have to be newer than the inputs.  The file modification
times of such "byproducts" are updated only when their content changes.
Then other build rules can depend on the byproducts explicitly so that
their dependents rebuild when the content of the original byproducts
really does change.

This "undeclared byproduct" approach is necessary for Makefile, VS, and
Xcode build tools because if a byproduct were listed as an output of a
rule then the rule would always rerun when the input is newer than the
byproduct but the byproduct may never be updated.

Ninja solves this problem by offering a 'restat' feature to check
whether an output was really modified after running a rule and tracking
the fact that it is up to date separately from its timestamp.  However,
Ninja also stats all dependencies up front and will only restat files
that are listed as outputs of rules with the 'restat' option enabled.
Therefore an undeclared byproduct that does not exist at the start of
the build will be considered missing and the build will fail even if
other dependencies would cause the byproduct to be available before its
dependents build.

CMake works around this limitation by adding 'phony' build rules for
custom command dependencies in the build tree that do not have any
explicit specification of what produces them.  This is not optimal
because it prevents Ninja from reporting an error when an input to a
rule really is missing.  A better approach is to allow projects to
explicitly specify the byproducts of their custom commands so that no
phony rules are needed for them.  In order to work with the non-Ninja
generators, the byproducts must be known separately from the outputs.

Add a new "BYPRODUCTS" option to the add_custom_command and
add_custom_target commands to specify byproducts explicitly.  Teach the
Ninja generator to specify byproducts as outputs of the custom commands.
In the case of POST_BUILD, PRE_LINK, and PRE_BUILD events on targets
that link, the byproducts must be specified as outputs of the link rule
that runs the commands.  Activate 'restat' for such rules so that Ninja
knows it needs to check the byproducts, but not for link rules that have
no byproducts.

Peter Collingbourne fe5d6e8c0f Add USES_TERMINAL option for custom commands
Teach the add_custom_command and add_custom_target commands a new
USES_TERMINAL option.  Use it to tell the generator to give the command
direct access to the terminal if possible.

Stephen Kelly b80557c7bd file(GENERATE): Evaluate early to allow generating source files
The evaluation files must be known before cmTargetTraceDependencies
attempts to find them, but we must actually generate the files after
cmTargetTraceDependencies, as that can add to target SOURCES.  The
limitation is that the generated output name must not depend on the
SOURCES of a target if the generated file is used by that target.

Mark the output files as GENERATED so that trace dependencies does
not expect them to already exist in the filesystem.

Move the invokation of ForceLinkerLanguage in the Generate logic
to after the generated file names are known.  ForceLinkerLanguage
tries to determine the sources of a target (in order to determine
an already-known language) and otherwise fails to get information
about the generated file.

Test that the output of file(GENERATE) can be used as a target source
file and that accessing the target SOURCES in the name of the output
file is an error.  Accessing the TARGET_OBJECTS would be a similar
error if it was legal to use that generator expression in this
context.  That is not currently possible and is a different error
condition, so test the current error output as a reminder to change
the expected output if that becomes possible in the future.  Test
that generated rule files resulting from cmTargetTraceDependencies
appear in the SOURCES generated in the output file.

Commit v2.8.11~156^2~2 (Expand includes and defines transitively

and a stack overflow during evaluation of a link implementation
which depends on a transitive property, such as

 add_library(empty1 ...)
 add_library(empty2 ...)
 target_link_libraries(empty1
   PRIVATE
     $<$<STREQUAL:$<TARGET_PROPERTY:INCLUDE_DIRECTORIES>,/foo/bar>:empty2>
 )

There is no use-case for code like that currently, but it should not
cause a stack overflow.

is found.

without using a shell or a full "cmake -P" script to wrap it.

Extend the RunCMake.CommandLine test to cover success and failure cases.

Brad King 0366ba5db6 Tests: Fix RunCMake.TargetSources on Xcode 1.5
Xcode 1.5 does not support multiple configurations.  The generator also
adds some sources internally that cause extra OriginDebug output.
Update the expected output to tolerate it.

Brad King 528e8af19f Allow a toolchain file to specify a generator toolset
Delay use of CMAKE_GENERATOR_TOOLSET until the CMakeSystem.cmake
file has been configured and loaded during the first project() or
enable_language() command.  This gives the toolchain file named by
CMAKE_TOOLCHAIN_FILE a chance to set CMAKE_GENERATOR_TOOLSET.  This
point is still early enough to set the generator toolset prior to
the initialization of any languages that might use the toolset.

The cmake::GeneratorToolset member variable remains an indication
of what was specified by the -T option or loaded from the cache.
It does not need to be updated based on the toolchain file setting.
The cmMakefile::TryCompile can still pass cmake::GeneratorToolset
into the inner instance because the try-compiled project will do
platform and language initialization using the CMakeSystem module
configured for the outer project.

Extend the RunCMake.GeneratorToolset test with cases that use a
toolchain file to set CMAKE_GENERATOR_TOOLSET.

Brad King 44e2923f33 cmake: Fix --build crash on bad CMAKE_GENERATOR in cache
If we fail to create the generator named by CMAKE_GENERATOR, exit
with an error message instead of crashing.  While at it, fix the
wording of the error message when CMAKE_GENERATOR is not set.

Extend the RunCMake.CommandLine test with cases covering the
"cmake --build" option when the named directory does not provide
a CMakeCache.txt with a valid CMAKE_GENERATOR.

Stephen Kelly 60a981ea8e Features: Enable compiler extensions by default.
Compilers enable their extensions by default, and disabling them
implicitly can lead to results which are surprising or non-obvious
to debug.

Allow setting build properties based on the features available
for a target.  The availability of features is determined at
generate-time by evaluating the link implementation.

Ensure that the <LANG>_STANDARD determined while evaluating
COMPILE_FEATURES in the link implementation is not lower than that
provided by the INTERFACE of the link implementation.  This is
similar to handling of transitive properties such as
POSITION_INDEPENDENT_CODE.
