When we kill a child we send SIGSTOP first so that we can traverse its
child processes recursively. On unwinding the recursion we then send
SIGKILL. Current Cygwin has trouble when both signals are sent in quick
succession by the parent process. Add a usleep(1) after sending the
first signal to give up our time slice and give Cygwin a chance to
process the first signal before sending the second.
The languages used in compiling STATIC libraries need to be propagated
to dependents regardless of the settings of INTERFACE_LINK_LIBRARIES or
CMP0022. They are independent of the libraries in the link interface.
Prior to commit v2.8.12~192^2~2 (Introduce the INTERFACE_LINK_LIBRARIES
property, 2013-06-04) the cmTarget::ComputeLinkInterface code path for
"explicitLibraries" could never be taken for STATIC libraries, so the
logic to propagate languages existed only in the non-explicitLibraries
code path. After that commit, INTERFACE_LINK_LIBRARIES could be set for
STATIC libraries to cause the "explicitLibraries" code path to be taken.
The commit also left the old non-explicitLibraries code path conditional
on CMP0022 not being set to NEW. Thus link language propagation was
left missing from two cases by that commit.
The explicitLibraries code path was fixed to propagate languages by
commit v2.8.12~149^2~1 (cmTarget: Fix iface libraries and languages for
static libraries, 2013-07-26). However, the non-explicitLibraries case
was never taught to propagate languages when CMP0022 is set to NEW. Fix
that now. Factor the logic to propagate link languages out of the link
interface libraries conditions so that it always occurs. Update
Tests/Fortran to set CMP0022 to NEW to test this case (because the test
passes only if link language propagation works).
Add ERROR_SHARING_VIOLATION to the set of errors (previously including
only ERROR_ACCESS_DENIED) that cause a rename (MoveFile) on Windows to
retry. The condition was observed when two renames to the same target
file name were happening simultaneously.
Since commit v3.0.0-rc1~305^2 (Ninja: deptype msvc for Intel's compiler
on Windows, 2013-11-25) we used "deps = msvc" for the Intel compiler.
This is correct only on Windows. On Linux we still want "deps = gcc".
Fix the logic to use "deps = msvc" when the compiler id or the "simulate
id" is "MSVC". This will preserve the behavior on Intel for Windows and
fix the behavior on Intel for Linux. In the future this should be
converted to a platform information module variable.
This policy should be checked at the call site that tries to access the
LOCATION property, not the directory scope containing the target.
Thread the caller context through cmTarget::GetProperty to use for
checking the policy setting and emitting a diagnostic with proper
backtrace.
Extend the RunCMake.CMP0026 test with a cross-directory case.
There are no versions of /MANIFESTUAC:NO where addition values are
appended. Remove both of the MANIFESTUAC:NO entries from our flag
tables and replace them with one which would set EnableUAC to false and
immediately stop processing the /MANIFESTUAC:NO option.
Drop the icon file extension. This fixes the desktop file validation
message:
"CMakeSetup32.png" for key "Icon" in group "Desktop Entry" is an icon
name with an extension, but there should be no extension as described in
the Icon Theme Specification if the value is not an absolute path

If creation of the global generator fails, return early with an error
message instead of trying to use the generator and crashing.
Add a CTestTestBadGenerator test to cover this case.

Include execinfo.h, cxxabi.h, and dlfcn.h under the same conditions
under which we use the APIs from them. Move their inclusion out of
OS-specific blocks.
This option was removed during conversion to the reStructuredText
documentation. Restore it. Process documentation starting at
Help/index.rst so that all manuals are included in the output.
Fix cmOSXBundleGenerator::CreateCFBundle to place Info.plist under the
same root directory as the rest of the bundle. Without this, Info.plist
was placed into CMAKE_BINARY_DIR, not CMAKE_CURRENT_BINARY_DIR because
the target path was not generated correctly.
These policies are triggered by the use of a particular compiler rather
than outdated CMake code in a project. Avoid warning in every project
that enables a language by not displaying the policy warning by default.
Add variable CMAKE_POLICY_WARNING_CMP<NNNN> to control the warning
explicitly; otherwise enable the warning with --debug-output or --trace.
This breaks with strict policy convention because it does not provide
developers with any warning about the behavior change by default.
Existing projects will continue to build without a warning or change in
behavior. When a developer changes the minimum required version of
CMake in a project to a sufficiently high value (3.0), the project will
suddenly get the new compiler id and may break, but at least the
breakage comes with a change to the project rather than the version of
CMake used to build it.
Breaking strict policy convention is worthwhile in this case because
very few projects will be affected by the behavior change but every
project would have to see the warning if it were enabled by default.
Restore support for the undocumented <CONFIG>_LOCATION target property
removed by commit v3.0.0-rc1~175^2 (cmTarget: Remove support for
<CONFIG>_LOCATION property, 2013-12-30) as part of the CMP0026 OLD
behavior.
Override the QT_QTMAIN_LIBRARY cache variable with a regular
variable in the Qt 5 configuration. This avoids linking with the
Qt 4 version of the WinMain library.
Visual Studio is handled as a special case for autogen depends. However,
the special handling works only for target dependencies, not file
dependencies output by a custom command.
Use a PRE_BUILD step only if all depends are targets.
My last related commit e5e3f3d4 (CTest: filter /showIncludes output from
ninja compile launcher, 2013-12-01) filtered /showIncludes messages from
the generated xml output but they also need to be filtered in
ScrapeLog(). Otherwise they are being detected as warnings when using
compilers withs english diagnostics.
Teach the install(FILES) and install(PROGRAMS) commands to evaluate
generator expressions in the list of files.
Extend the ExportImport test to cover installation cases involving
generator expressions.
Add a Makefile member to the cmInstallFilesGenerator class and
populate it on construction. This will be useful in a following
change to evaluate generator expressions with proper context.
Historically CMake used three version components for the feature level.
We released new features while incrementing only the third version
component. Since commit v2.8.2~105^2~4 (New version scheme to support
branchy workflow, 2010-04-23) we used the fourth version component for
bug-fix releases and the development date:
<major>.<minor>.<patch>[.<tweak>][-rc<n>] = Release
<major>.<minor>.<patch>.<date>[-<id>] = Development
This solidified use of three components for the feature level, and was
necessary to continue releasing 2.x versions because:
* Some existing projects performed floating-point comparisons of
${CMAKE_MAJOR_VERSION}.${CMAKE_MINOR_VERSION} to 2.x numbers
so ``x`` could never be higher than 9.
* Version 2.9.<date> was used briefly in post-2.8.0 development in
CVS prior to the transition to Git, so using it in releases may
have caused confusion.
Now that we are moving to 3.x versions, these two restrictions go away.
Therefore we now change to use only two components for the feature
level and use the scheme:
<major>.<minor>.<patch>[-rc<n>] = Release
<major>.<minor>.<date>[-<id>] = Development
