* Fix newly discovered clang-tidy issuesDaniel Pfeifer2016-10-211-6/+6
| | | | | | | Clang-tidy reports some issues only from the currently compiled source file and its associated header file. Separating the compilation of commands exposed some clang-tidy issues that were not reported previously. Fix them.

* Simplify CMake per-source license noticesBrad King2016-09-271-12/+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copyright/license notice headers that spell out copyright holder names and years are hard to maintain and often out-of-date or plain wrong.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.

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 King2016-04-291-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Source: Stabilize include orderBrad King2016-04-291-0/+1
| | | | | Each source file has a logical first include file. Include it in an isolated block so that tools that sort includes do not move them.

| * cmConditionEvaluator: Pre-allocate keyword stringsBrad King2016-03-291-31/+58
| | | | | | | | | | | | Calls to `IsKeyword("...")` cause runtime construction of std::string. Avoid possible repeated allocation by pre-allocating keyword strings during initialization.
* | cmConditionEvaluator: Remove GetConditionContext methodBrad King2016-03-291-12/+0
| | | | | | | | | | All it does is call cmListFileContext::FromCommandContext, so move this to the call sites.
* | cmConditionEvaluator: Drop unnecessary path conversionBrad King2016-03-291-8/+1
|/ | | | | | | | | | In commit v3.4.0-rc2~1^2 (cmIfCommand: Issue CMP0054 warning with appropriate context, 2015-10-20) we added construction of a cmListFileContext with conversion of the calling file path. This code path runs on every condition (e.g. `if()`) and so the path conversion has a noticeable performance cost. Fortunately the only use of this context is for insertion into cmMakefile::CMP0054ReportedIds so we do not need to convert the path. Simply drop the conversion.
* cmConditionEvaluator: Fix matching of `CMAKE_MATCH_*` values (#15944)Brad King2016-02-011-0/+10
| | | | | | | | | | | While evaluating `if(MATCHES)` we get a `const char*` pointer to the string to be matched. On code like if(CMAKE_MATCH_COUNT MATCHES "Y") the string to be matched may be owned by our own result variables. We must move the value to our own buffer before clearing them. Otherwise we risk reading freed storage.
* cmIfCommand: Issue CMP0054 warning with appropriate context. (#15802)Stephen Kelly2015-10-201-5/+35
| | | | | | | | | | | | | | | Commit v3.4.0-rc1~494^2~4 (cmMakefile: Add API for elseif to create backtrace., 2015-05-29) removed the use of cmMakefileCall to push/pop execution context in favor of a new way to create backtraces. However, a call to cmMakefile::GetExecutionContext is still invoked to issue a contextual CMP0054 warning through cmConditionEvaluator. As the elseif is not part of the call stack, this resulted in trying to access an empty vector. Avoid the attempt at getting execution context when evaluating elseif by constructing a context and backtrace on behalf of the cmConditionEvaluator in all cases.
* if: Add "TEST <test>" conditionMatt McCormick2015-08-031-1/+25
| | | | | | | | if(TEST TestNameThatExists) will return true if a test with the name TestNameThatExists has been added with add_test. The syntax is similar to if(TARGET TargetName). Since use of "TEST" as an argument to if() could previously be interpreted as a non-keyword argument, add policy CMP0064 to treat it as a keyword as NEW behavior.

| | | | | This is cheaper than getting the whole backtrace, and the cmListFileBacktrace will not always be composed of cmListFileContext objects.

* cmMakefile: store the number of last matches in a CMake varBen Boeckel2014-12-031-3/+2
| | | | | | | | | With PushScope and PopScope, keeping track of another bit of data for each scope isn't easy. Instead, store it as another CMake variable so it gets implicitly tracked along with everything else. This works in a revert of commit 7d674b5f0b28a610333644d417c2e8cb796cc9e4.
* Revert "ClearMatches: Only clear matches which were actually set" (#15261)Ben Boeckel2014-11-261-2/+3
| | | | | | | | | | | This reverts commit v3.1.0-rc1~557^2~2 (ClearMatches: Only clear matches which were actually set, 2014-03-12). The optimization did not track the match count in the same scope as the variables, allowing possible inconsistency. Resolve conflicts in Source/cmIfCommand.cxx, Source/cmMakefile.cxx, and Source/cmMakefile.h by moving the changes to the new location of the code involved.
