Ben Boeckel 270eb96df0 strings: Remove cmStdString references
Casts from std::string -> cmStdString were high on the list of things
taking up time. Avoid such implicit casts across function calls by just
using std::string everywhere.

The comment that the symbol name is too long is no longer relevant since
modern debuggers alias the templates anyways and the size is a
non-issue since the underlying methods are generated since it's
inherited.

Brad King 7b1f966a6c Windows: Make file delete/rename retry configurable
Several CMake operations need to replace files in rapid succession.
This commonly fails on Windows due to filesystem lock behavior so
we have retry loops.  No matter how many times we retry or how long
we delay there will inevitably be someone with an environment that
needs more.  Make the retry count and delay configurable in the
Windows Registry keys:

 {HKCU,HKLM}/Software/Kitware/CMake/Config

in DWORD values

 FilesystemRetryCount = Number of tries
 FilesystemRetryDelay = Delay in milliseconds between tries

Leave the feature undocumented for now to see how it goes.

Brad King d1526f825e Refactor internal resource location APIs and initialization
Rename cmSystemTools::FindExecutableDirectory to FindCMakeResources.
Teach it to compute the locations of cmake, ctest, cpack, ccmake, and
cmake-gui executables, and the location of CMAKE_ROOT.  Provide this
information from static cmSystemTools::Get<resource>() methods.
Refactor code that needs these locations to use the new APIs.

Teach FindCMakeResources to use the OS X system API to lookup the
executable location.  When running from the CMake build tree itself,
leave a file in the tree that FindCMakeResources can use to read the
location of the source tree.  This avoids the need to compile the source
tree location into a binary that may be installed and used without the
source tree.

Teach the QtDialog on OS X to create a "cmake-gui" symlink in the build
tree next to "cmake" and the other tools, as is already done in the
install tree for the application bundle.  This ensures a consistent set
of executables are available in one directory.

Brad King 4c383b52d0 cmake: Avoid '-E tar' failure to extract symlinks on Windows (#13251)
If a symlink fails to extract and the host system is Windows then report

archives containing symbolic links to be extracted on Windows with
somewhat gracefully degraded behavior.

Brad King 45d2966dcc VS: Avoid leaking child process output back to IDE (#14266)
The VS IDE sets the environment variable VS_UNICODE_OUTPUT when
executing build rules in order to tell MS tools to report output through
a back door instead of through stdout/stderr.  Unset this variable so
that CMake can capture or properly redirect all output from processes it
runs even when running inside a VS IDE build environment.

This generalizes the special cases fixed by commit 80d045b0 (When
GetPrerequisites.cmake runs dumpbin while running inside the VS IDE...,
2008-05-01) and commit 44aff73d (ExternalProject: Avoid bleed-through
output when logging, 2011-01-06), so drop special handling of
VS_UNICODE_OUTPUT in those instances.

Brad King 59b568e5e8 Fix cmSystemTools::RenameFile race on Windows
Since commit d46d8df0 (Re-implemented cmGeneratedFileStream to look like a
real stream and replace the destination file atomically, 2004-11-03) our
RenameFile implementation tries to deal with MoveFile not replacing
read-only files.  In order to avoid the Get/SetFileAttributes pair we used
stat to test for existence of the destination file.  This has a race in
which the destination could be created between the test for existence and
the MoveFile call.

Remove the stat call and use GetFileAttributes to detect whether the file
exists.  This shortens the race but does not eliminate it.  Use a loop to
try multiple times in case we lose the race.  While at it, drop Win9x
support and always use MoveFileEx.

Clinton Stimpson 131eed6607 cmake-gui: Improve interrupt granularity to fix bug 12649.
Instead of enabling interrupt only when a progress or message callback is called, add a new callback specifically for
interrupt.  This new callback is called from GetFatalErrorOccured() so cmake-gui can immediately report interrupt status
instead of calling queuing a call to cmSystemTools::SetFatalErrorOccured() and waiting for the progress or message
callback to be called to process that queued call.

Bill Hoffman fb51d98562 Switch to using libarchive from libtar for cpack and cmake -E tar
This allows for a built in bzip and zip capability, so external tools
will not be needed for these packagers.  The cmake -E tar xf should be
able to handle all compression types now as well.

Brad King 96afb12087 Convert CMake to OSI-approved BSD License
This converts the CMake license to a pure 3-clause OSI-approved BSD
License.  We drop the previous license clause requiring modified
versions to be plainly marked.  We also update the CMake copyright to
cover the full development time range.

Brad King b41a548d86 Add parentheses around '&&' between '||' for gcc
The GNU compiler warns about possible operator precedence mistakes and
asks for explicit parentheses (-Wparentheses).  We add the parentheses
to silence the warning.  This also fixes one real logic error in the
find_package() implementation by correcting expression evaluation order.
