Follow up commit 1de08685 (cmSystemTools: Restore unreachable return to
silence warnings, 2014-04-02) by excluding the unreachable return on the
HP compiler as well as Clang. Both recognize that it is unreachable and
warn.
Some compilers do not recognize that the end of copy_data cannot
be reached and complain that there is no return statement. Clang
warns that there is an unreachable return statement if it appears.
Conditionally add the return statement when not building with Clang.
Use the clang RemoveCStrCalls tool to automatically migrate the
code. This was only run on linux, so does not have any positive or
negative effect on other platforms.
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.
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.

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.
If a symlink fails to extract and the host system is Windows then report
a warning and skip the entry instead of failing. This will allow
archives containing symbolic links to be extracted on Windows with
somewhat gracefully degraded behavior.
Simplify extraction message logic to be easier to follow and to write a
newline before any error messages that may be produced. Also flip
handling of the archive_write_header return code to handle success in
the "then" case and failure in the "else" case.
Install the Help directory next to Modules to make it available in CMake
distributions. Use cmRST to read Help .rst documents and print them as
help output.
Add options
--help-manual-list
--help-manual
to list available manuals or print one of them. Implement the options
--help-commands
--help-modules
--help-policies
--help-properties
--help-variables
by mapping to the corresponding manual page. Implement the options
--help-command-list
--help-module-list
--help-policy-list
--help-property-list
--help-variable-list
by globbing the available Help .rst documents of the corresponding type
and reading their titles. Implement the options
--help-command
--help-module
--help-policy
--help-property
--help-variable
by globbing the matching Help .rst document(s) and printing them.
Pass the original file handles to the native tool when using the
--use-stderr option in the build command. This enables the
usage of advanced terminal features like colored output.
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.
While calculating dependencies collapse sequences such as
../../../a/b/c/../../d/e/../../e/f
to avoid total path lengths over the Windows path length limit as much
as possible.
RPATH support is activated on targets that have the MACOSX_RPATH
property turned on.
For install time, it is also useful to set INSTALL_RPATH to help
find dependent libraries with an @rpath in their install name.
Also adding detection of rpath conflicts when using frameworks.
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.
This is for consistency throughout cmake. The cmsys version exists
becaues uses of auto_ptr types as return types does not work with
some implementations in ancient compilers.
Replace use of AppendEnv/RestoreEnv pairs with instances of
SaveRestoreEnvironment. Simplify the signature of AppendEnv and use it
in place of similar loops elsewhere. Move the RestoreEnv implementation
inside the SaveRestoreEnvironment destructor which is the only place
left that calls it.
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.
Define an abstract API around the backend hash algorithm. Expose
ifstream errors to HashFile callers. Always try opening the file.
Succeed only if the end of file is reached without error.

Use static_cast to avoid warnings like

conversion to ‘unsigned int’ from ‘__suseconds_t’ may alter its value
We do not care if the value is truncated because we are looking for just
32 bits anyway.
The Sun compiler does not provide the proper vector constructor to
initialize it from an iterator pair of a non-matching type. Extend the
ParseUnixCommandLine API to provide a vector of the proper type so no
conversion is needed.
The naive time(0) seed is unique only within one second. Instead try to
read a real source of entropy and otherwise fall back to a combination
of the process id and high-resolution time.
This will be needed to use cmArchiveWrire in cmCPackArchiveGenerator
with the same feature set as before. Note that adding zip
support to libarchive-wrapper would also makes it easy to add
a new -E zip command to cmake commands.
Use libarchive through class cmArchiveWrite to implement the method
cmSystemTools::CreateTar. The class includes entries for directories by
automatically traversing the tree on disk.
Since commit "Switch to using libarchive from libtar" (2009-10-30) the
the implementation of "tar xz" has printed all paths from the tarball as
a single line with no separator. This fixes the logic to extract
silently as expected.
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.
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.
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.
The superclass of cmSystemTools is cmsys::SystemTools, which should be
referencable by just SystemTools from inside the class. Borland C++
does not seem to support this, so we use cmSystemTools instead.
The system tools GetParentDirectory method no longer removes the root
path component. This fixes cmSystemTools::FileExistsInParentDirectories
to not infinitely loop at when GetParentDirectory stops at the root.
The cmSystemTools::RenameFile method returns type bool, but its
implementation on Windows returns the result of an API function that
returns BOOL. This change avoids the compiler warning.
This moves the cmGeneratedFileStream::RenameFile method implementation
into cmSystemTools. It works only within a single filesystem volume,
but is atomic when the operating system permits.
This class provides easy syntax to efficiently insert blocks of data
into XML documents with proper escapes. It replaces the old
cmCTest::MakeXMLSafe and cmSystemTools::MakeXMLSafe methods which
allocated extra memory instead of directly streaming the data.
During installation the RPATH and RUNPATH entries of ELF binaries are
edited to match the user specification. Usually either one entry is
present or both entries refer to the same string literal. In the case
that they are both present and refer to separate string literals we need
to update both. I have never seen this case in practice, but we should
do this just in case.
Removal of the RPATH and RUNPATH from ELF binaries must work when both
entries are present. Both entries should be removed. Previously only
one would be removed and the other would be blanked because it pointed
at the same string which was zeroed. This fixes gentoo bug number
224901.
- Add an argument to registry read/write/delete methods to specify
a 32-bit or 64-bit view.
- Default is the bit-ness of the running program.
- See issue #7095.
- Move computation of extended build-tree rpath
to cmComputeLinkInformation
- Only enable the extended build-tree rpath if
the target will be installed
- Generalize the interface of file(CHRPATH)
- When changing the rpath on installation only
replace the part generated by CMake because
the native tools (ex SunCC on Linux) might have
added their own part to the rpath
- Add cmSystemTools::ChangeRPath method
- Add undocumented file(CHRPATH) command
- When installing use file(CHRPATH) to change the rpath
instead of relinking
- Remove CMAKE_CHRPATH lookup from CMakeFindBinUtils
- Remove CMAKE_USE_CHRPATH option since this should
always work
- Reduce false positives in cases of unknown soname
- Make library extension regular expressions match only at end of string
- When linking to libraries in implicit dirs convert to the -l option
only if the file name is one that can be found by the linker
(ex. /usr/lib/libfoo.so.1 should be linked by full path)
- Add cmSystemTools::GuessLibrarySOName to guess the soname of a
library based on presence of a symlink
- In cmComputeLinkInformation try to guess an soname before assuming
that a third-party library is built without an soname
- In cmOrderDirectories guess the soname of shared libraries in cases
it is otherwise unknown
