Brad King 1763c31c3b Set policy CMP0025 to NEW while building CMake itself
CMake is aware of the policy's NEW behavior and the AppleClang compiler
id.  Set the policy to NEW explicitly to avoid the warning and get the
NEW behavior.

Also teach the RunCMake test infrastructure to build tests with
-DCMAKE_POLICY_DEFAULT_CMP0025=NEW to avoid the policy warning
in test output that must match specific regular expressions.

Brad King 221b5b6977 KWSys: Remove dependencies on FundamentalType
The hash_fun.hxx header is configured whether FundamentalType is enabled
or not and so cannot depend on it.  Run the relevant platform tests
whether or not FundamentalType is on and configure the result directly
into hash_fun.  While at it, remove the dependence of SystemInformation
on FundamentalType too since it needs only information that we now
always compute.

e48796b KWSys: Fix SystemTools environment memory handling (#13156)

2012-05-01 14:09:12 -04:00
Brad King e48796b26b KWSys: Fix SystemTools environment memory handling (#13156)
The SystemTools::PutEnv function tries to provide the "putenv" API
without leaking memory.  However, the kwsysDeletingCharVector singleton
frees memory that may still be referenced by the environment table,
having been placed there by putenv.  If any static destruction or
processing by an external tool happens after the singleton is destroyed
and accesses the environment it will read invalid memory.

Replace use of putenv with setenv/unsetenv when available.  The latter
manage internal copies of the values passed instead of referencing the
original memory.  When setenv/unsetenv are not available use putenv with
a singleton that removes its values from the environment before freeing
their memory.  This requires an "unputenv" implementation.  On at least
some platforms it must be written in terms of "putenv" because other
APIs are not available and direct modification of the "environ" global
is not safe (e.g. on Windows there is interaction with "wenviron").
Fortunately either putenv("A=") or putenv("A") will remove "A" from the
environment on these platforms.  On other platforms fall back to direct
manipulation of "environ".

Also add UnPutEnv to the API and add a test for the behavior of both.

Brad King 5f807a62a5 KWSys: Remove DateStamp
KWSys is no longer shared in projects via a server-side directory
symlink in CVS.  An automated nightly date stamp commit can no longer be
shared by multiple projects directly.  It needs a per-project replay
robot so the nightly commits end up needing N+1 robots instead of N.
Remove the DateStamp feature because it is no longer useful or
maintained by nightly commits.

Brad King 29487bacea KWSys: Do not trust EXECUTABLE_OUTPUT_PATH for ProcessFwd9x encoding

Brad King ffac70b528 KWSys: Use EXPORT name only if installing library

KWSYS_INSTALL_EXPORT_NAME.  Require KWSYS_INSTALL_LIB_DIR to be set too.

Brad King 3b26fa13c4 KWSys: Optionally suppress consistent test failures

Brad King b84220b287 KWSys: Use short fallback timeout for Process tests
If any of the KWSys Process tests take more than a minute or two then
something is wrong.  There is no need to wait for a long default
timeout.

Brad King 5c16024fbb KWSys: Pass ptrdiff_t check result to System.c
Since commit "Provide unix-sytle command line parsing" (2009-07-13) the
reference to KWSYS_C_HAS_PTRDIFF_T in System.c has been meaningless
because the macro was never passed to the compiler!

Brad King 3f92947524 KWSys: Configure DynamicLoader library prefix/suffix
The DynamicLoader::LibPrefix and DynamicLoader::LibExtension methods
previously hard-coded the module name components for each platform.  Set
them from the CMAKE_SHARED_MODULE_PREFIX and CMAKE_SHARED_MODULE_SUFFIX
CMake variables instead.  This ensures consistency in a program that
uses these methods to construct the file names for its own modules.

Brad King 357096d35a KWSys: Build tests after libraries
The TestSharedForward executable and TestDynload module do not actually
link to a KWSys library, but it is nice to build them after the
libraries just like all other test binaries.

This also works around a universal binary bug in Xcode 2.x.  It forgets
to create the output directory for the executable before linking it.  We
avoid the problem by putting the library in the directory first.

Brad King 15316c12f5 KWSys: Remove default exe output path
KWSys should not set variables outside its namespace.  It can honor the
EXECUTABLE_OUTPUT_PATH set by a host project, but tere is no need for it
to set a default in the host project cache.

Brad King 9ec851bc90 KWSys: Set CMP0003 to NEW
The commit "Enable loose loop constructs in KWSys" set the minimum
required CMake version to 2.4.5.  This regressed the setting of CMP0003,
so we restore it in this commit.

Brad King bbbdf54a35 Fix KWSys FundamentalType for Universal Binaries
The FundamentalType header needs to know type sizes at preprocessing
time.  This commit teaches it to avoid using CHECK_TYPE_SIZE because the
macro does not work for types whose size varies across architectuers in
Mac OS X universal binaries.  Fortunately the Mac compilers provide just
enough information to detect the needed type sizes during preprocessing.

We now use preprocessor macros instead of configuration tests whenever
they are available.  As a side effect this reduces the number of
try-compiles needed with GCC.

See issue #9913.

Brad King 2d80c9e31a Check for 'long long' without computing size
In KWSys IOStream we need to detect whether 'long long' exists but we do
not need its size.  We avoid using CHECK_TYPE_SIZE because it does not
work for types whose size varies across architectuers in Mac OS X
universal binaries.  See issue #9913.

Brad King de955e4b6d Convert KWSys to OSI-approved BSD License
This converts the KWSys 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 KWSys copyright to
cover the full development time range.

Brad King 832f0a88f0 Install KWSys Copyright.txt as documentation
This commit adds KWSys configuration option KWSYS_INSTALL_DOC_DIR to
specify the directory for installation of documentation.  We use it to
put the KWSys Copyright.txt file at the location

  ${KWSYS_INSTALL_DOC_DIR}/${KWSYS_NAMESPACE}/Copyright.txt

in the project installation tree.  This helps containing projects meet
the license requirement to distribute the copyright and license with
binary forms.

Brad King 207aab6acf Define kwsys_ios_binary macro for std::ios::binary
The 'binary' openmode does not exist on all compilers.  We define macro
<kwsys>_ios_binary, where <kwsys> is the KWSys namespace, to refer to
std::ios::binary if it exists and 0 otherwise.  Sample usage:

  kwsys_ios::ifstream fin(fn, kwsys_ios::ios::in | kwsys_ios_binary);

Brad King cf1225b9af BUG: Enable large files only if <cstdio> works
Some AIX/gcc version combinations the <cstdio> header breaks when large
file support is enabled.  See this GCC issue for details:

  http://gcc.gnu.org/bugzilla/show_bug.cgi?id=20366

We work around the problem by enhancing the configuration check for
large file support to include <cstdio> when available.  This will cause
LFS to be disabled when the above problem occurs.

Brad King 776e21d1c7 COMP: Avoid String.c inclusion by Compaq templates
The Compaq compiler (on VMS) includes 'String.c' in source files that
use the stl string while looking for template definitions.  This was the
true cause of double-inclusion of the 'kwsysPrivate.h' header.  We work
around the problem by conditionally compiling the entire source file on
a condition only true when really building the source.

Brad King 32be27c6de BUG: Enforce KWSys component dependencies early
KWSys component dependencies must be enforced before any tests for
enabled components are done.  This moves the dependency enforcement code
to be as early as possible.

Brad King 6a906befae ENH: In KWSys set the IMPLICIT_DEPENDS_INCLUDE_TRANSFORM property.
- Tells CMake about the KWSYS_HEADER macro.
  - Enables implicit dependencies of private source files.
  - When a CMake new enough to support the property is required
    the "#if 0" hack can be removed from the source files.
