Brad King 0c7f84ca41 KWSys Process: Workaround child kill trouble on Cygwin
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.

Brad King 40b9cd0f61 CMP0022: Fix link language propagation in NEW behavior
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).

Joseph Snyder 9ad07fbeb8 CTest: Fix MUMPS coverage parsing and test
Fix the MUMPS coverage parser:

* Account for tabs after entry points

* Stop double incrementing lines that have explicit calls to the 0 line

* If a line has been previously marked as non executable, but then
  contains a count, increment it an extra one to push it back into
  the executable code set.

Add a custom routine and corresponding coverage files in the test case.
This file is smaller and has cmcov/mcov files that have data for only
that routine.

When a project is packaged for redistribution the local package
registries should not be updated or consulted.  They are for developers.

Add variables to disable use of package registries globally:

* CMAKE_EXPORT_NO_PACKAGE_REGISTRY that disables the export(PACKAGE)
  command
* CMAKE_FIND_PACKAGE_NO_PACKAGE_REGISTRY that disables the User Package
  Registry in all the find_package calls.
* CMAKE_FIND_PACKAGE_NO_SYSTEM_PACKAGE_REGISTRY that disables the
  System Package Registry in all the find_package calls.

Update documentation and unit tests.

Brad King 54535f4730 Ninja: Fix deptype for Intel compiler on Linux
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.

Brad King dc3c210244 OS X: Package with DragNDrop instead of PackageMaker
Use the CPack DragNDrop generator instead of the deprecated PackageMaker
tool to package CMake itself.  This provides an installation experience
that is more consistent with other products on OS X and allows users to
select the destination directory easily.  It also avoids installing
"/private/var/db/receipts/com.Kitware.CMake.*" receipts that must be
removed by "pkgutil --forget com.Kitware.CMake" before another version
of CMake can be installed.

The DragNDrop installer does not support a post-flight script, so drop
our configuration of it.  The cmake-gui has an option for installing
symbolic links to enable command-line use.  In practice users may simply
add "/Applications/CMake.app/Contents/bin" to their PATH instead.

Ben Boeckel bc38565863 EVIS: Reimplement using custom parsing code
Introduce a new implementation of ExpandVariablesInString and select
between the old and new implementations based on policy CMP0053.
Instead of cmCommandArgumentParserHelper, use a custom parser with our
own stack.  This is much faster and works well for our simple grammar.

The new behavior of CMP0053 should expand @VAR@ syntax only in certain
contexts.  All existing EVIS callers use "replaceAt == true" so
hard-code our call to the old implementation.  Update the signature to
default to "replaceAt == false" and pass "replaceAt == true" explicitly
in the call sites for configure_file and string(CONFIGURE).

Testing the configure (no generate) step with ParaView shows ~20%
performance improvement.

In terms of complete configure/generate steps, further testing with
ParaView shows a 20% performance improvement over 2.8.12.2 with Unix
Makefiles and minimal with Ninja. Ninja is less because it generate step
is the expensive part (future work will address this) by a long shot and
these changes help the configure step for the most part.

Brad King 5411128645 ctest_build: Do not crash on bad generator name
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.

Mikołaj Siedlarek 1bed75a590 OS X: Use -iframework for system framework directories
Just like -I flag has its -isystem counterpart which marks an include
directory as a system directory and prevents unwanted warnings, on Apple
systems there is -iframework -- a system directory replacement for -F.
Use this flag to implement include_directories(SYSTEM) for frameworks.

Stephen Kelly 205215fb8a cmTarget: Add CXX_STANDARD_REQUIRED to control decay. 2014-05-07 12:17:49 +02:00
Stephen Kelly 1df2116bfa Features: Decay language flag if requested is not available.
Use the highest standard compile flags available if requested language
version is too new.

This supports use-cases like

 set(CMAKE_CXX_STANDARD 14)

 # Compiled with -std=c++11 with GNU 4.7, which has no -std=c++14
 # or equivalent flag
 add_executable(main main.cpp)

This can be used in combination with preprocessor defines which
communicate the availability of certain language features for
optional use.

Stephen Kelly d648c4766f cmTarget: Don't assert on object libraries for configure-time location.
Commit b8af2011 (cmTarget: Fix listing of source files at
configure-time., 2014-04-13) refactored a GetObjectLibrariesCMP0026
method out of GetLanguages.  In flight, a conditional use of a target
if available was changed to an assert-available.

This code is only used to read the LOCATION property at configure
time, when the link information is incomplete, and not all targets
are defined, so the assert is inappropriate, even though it can lead
to incorrect information being generated.  CMP0026 warns about the
potentially incorrect information anyway.

Streams are expensive to construct (looks like some locale-related
stuff), so use strings instead.

As a 'built-in' variable it imposes a cost on all variable lookups
