* Simplify CMake per-source license noticesBrad King2016-09-271-11/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | Per-source copyright/license notice headers that spell out copyright holder names and years are hard to maintain and often out-of-date or plain wrong. Precise contributor information is already maintained automatically by the version control tool. Ultimately it is the receiver of a file who is responsible for determining its licensing status, and per-source notices are merely a convenience. Therefore it is simpler and more accurate for each source to have a generic notice of the license name and references to more detailed information on copyright holders and full license terms. Our `Copyright.txt` file now contains a list of Contributors whose names appeared source-level copyright notices. It also references version control history for more precise information. Therefore we no longer need to spell out the list of Contributors in each source file notice. Replace CMake per-source copyright/license notice headers with a short description of the license and links to `Copyright.txt` and online information available from "https://cmake.org/licensing". The online URL also handles cases of modules being copied out of our source into other projects, so we can drop our notices about replacing links with full license text. Run the `Utilities/Scripts/filter-notices.bash` script to perform the majority of the replacements mechanically. Manually fix up shebang lines and trailing newlines in a few files. Manually update the notices in a few files that the script does not handle.
* cmState: Record buildsystem target names in each directoryBrad King2016-09-191-0/+2

| | | | | | | Use clang-tidy's performance-unnecessary-value-param checker to find value parameter declarations of expensive to copy types that are not modified inside the function. Ignore findings in kwsys. After applying the fix-its, manually change `const T&` to `T const&`.

| | | | | | | | | | | | | Run the `Utilities/Scripts/clang-format.bash` script to update all our C++ code to a new style defined by `.clang-format`. Use `clang-format` version 3.8. * If you reached this commit for a line in `git blame`, re-run the blame operation starting at the parent of this commit to see older history for the content. * See the parent commit for instructions to rebase a change across this style transition commit.
* Format include directive blocks and ordering with clang-formatBrad King2016-04-291-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Sort include directives within each block (separated by a blank line) in lexicographic order (except to prioritize `sys/types.h` first). First run `clang-format` with the config file: --- SortIncludes: false ... Commit the result temporarily. Then run `clang-format` again with: --- SortIncludes: true IncludeCategories: - Regex: 'sys/types.h' Priority: -1 ... Commit the result temporarily. Start a new branch and cherry-pick the second commit. Manually resolve conflicts to preserve indentation of re-ordered includes. This cleans up the include ordering without changing any other style. Use the following command to run `clang-format`: $ git ls-files -z -- \ '*.c' '*.cc' '*.cpp' '*.cxx' '*.h' '*.hh' '*.hpp' '*.hxx' | egrep -z -v '(Lexer|Parser|ParserHelper)\.' | egrep -z -v '^Source/cm_sha2' | egrep -z -v '^Source/(kwsys|CursesDialog/form)/' | egrep -z -v '^Utilities/(KW|cm).*/' | egrep -z -v '^Tests/Module/GenerateExportHeader' | egrep -z -v '^Tests/RunCMake/CommandLine/cmake_depends/test_UTF-16LE.h' | xargs -0 clang-format -i This selects source files that do not come from a third-party.

* cmListFileBacktrace: Refactor storage to provide efficient value semanticsBrad King2016-04-181-14/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since commit v3.4.0-rc1~321^2~2 (Genex: Store a backtrace, not a pointer to one, 2015-07-08) we treat cmListFileBacktrace instances as lightweight values. This was true at the time only because the backtrace information was kept in the cmState snapshot hierarchy. However, that forced us to accumulate a lot of otherwise short-lived snapshots just to have the backtrace fields available for reference by cmListFileBacktrace instances. Recent refactoring made backtrace instances independent of the snapshot hierarchy to avoid accumulating short-lived snapshots. This came at the cost of making backtrace values heavy again, leading to lots of string coying and slower execution. Fix this by refactoring cmListFileBacktrace to provide value semantics with efficient shared storage underneath. Teach cmMakefile to maintain its call stack using an instance of cmListFileBacktrace. This approach allows the current backtrace to be efficiently saved whenever it is needed. Also teach cmListFileBacktrace the notion of a file-level scope. This is useful for messages about the whole file (e.g. during parsing) that are not specific to any line within it. Push the CMakeLists.txt scope for each directory and never pop it. This ensures that we always have some context information and simplifies cmMakefile::IssueMessage. Push/pop a file-level scope as each included file is processed. This supersedes cmParseFileScope and improves diagnostic message context information in a few places. Fix the corresponding test cases to expect the improved output.
* cmState: Avoid accumulating snapshot storage for backtracesBrad King2016-04-151-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Changes during post-3.3/pre-3.4 development refactored storage of most configure-time information, including variable bindings and function scopes. All scopes (even short-lived) were kept persistently for possible future debugging features, causing huge accumulated memory usage. This was mostly addressed by commit v3.4.1~4^2 (cmState: Avoid accumulating snapshot storage for short-lived scopes, 2015-11-24). Since then we still keep short-lived scopes when they are needed for a backtrace. This is because since commit v3.4.0-rc1~378^2 (cmListFileBacktrace: Implement in terms of cmState::Snapshot, 2015-05-29) backtraces have been lightweight objects that simply point into the snapshot tree. While the intention of this approach was to avoid duplicating the call stack file path strings, the cost turned out to be holding on to the entire call stack worth of scope snapshots, which is much worse. Furthermore, since commit v3.4.0-rc2~1^2 (cmIfCommand: Issue CMP0054 warning with appropriate context, 2015-10-20) all conditions used in `if()` commands hold a backtrace for use in diagnostic messages. Even though the backtrace is short-lived it still causes the scope snapshot to be kept. This means that code like function(foo) if(0) endif() endfunction() foreach(i RANGE 1000000) foo() endforeach() accumulates storage for the function call scope snapshots. Fix this by partially reverting commit v3.4.0-rc1~378^2 and saving the entire call stack during cmListFileBacktrace construction. This way we can avoid keeping short-lived scope snapshot storage in all cases.
