| * cmMakefile: Implement LinkLibraries as an internal propertyStephen Kelly2016-10-071-7/+0
| | | | | | | | | | | | | | | | | | cmMakefile should not have logic particular to individual cmake commands. The link_libraries() command is generally obsolete in favor of target_link_libraries(). An alternative language for CMake probably would not offer the former. The quirks and historical behaviors of the current language should be separate from the core classes of CMake to allow replacing the language.

* 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copyright/license notice headers that spell out copyright holder names and years are hard to maintain and often out-of-date or plain wrong.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.

* Avoid using KWSys auto_ptr by adopting it ourselvesBrad King2016-06-291-7/+6
| | | | | | | | | | | | Replace use of cmsys::auto_ptr with a CM_AUTO_PTR macro that maps to our own implementation adopted from the KWSys auto_ptr implementation. Later we may be able to map CM_AUTO_PTR to std::auto_ptr on compilers that do not warn about it. Automate the client site conversions: git grep -l auto_ptr -- Source/ | grep -v Source/kwsys/ | xargs sed -i \ 's|cmsys::auto_ptr|CM_AUTO_PTR|;s|cmsys/auto_ptr.hxx|cm_auto_ptr.hxx|'

* Format include directive blocks and ordering with clang-formatBrad King2016-04-291-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 King2016-04-181-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Rename local target lookup methods to clarify purposeBrad King2016-04-011-1/+1
| | | | | | | | | | Rename methods: * `cmMakefile::Find{ => LocalNonAlias}Target` * `cmLocalGenerator::Find{ => LocalNonAlias}GeneratorTarget` These names clarify that they are for directory-local target names and do not consider alias targets.
* Fix lookup of an ALIAS target outside aliased target's directory (#16044)Brad King2016-04-011-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | Refactoring in commit v3.5.0-rc1~272^2~11 (cmTarget: Implement ALIAS in terms of name mapping, 2015-10-25) accidentally introduced logic that assumes ALIAS targets always reference targets in their own directory. Fix this and add a test case. The configure-step fix is that `cmMakefile::FindTarget` should not consider aliases. The purpose of this method is just to look up targets local to a directory. Since ALIAS and normal targets share a namespace we know a locally defined target will never collide with an ALIAS target anyway. The method has 3 call sites, and this change is safe for all of them: * `cmInstallCommand::HandleTargetsMode`: Rejects aliases before the call. * `cmFLTKWrapUICommand::FinalPass`: Should never have considered aliases. * `cmMakefile::FindTargetToUse`: Falls back to a global lookup anyway. The generate-step fix is that `cmLocalGenerator::FindGeneratorTarget` should not consider aliases. This method is the generate-step equivalent to the above. The method has 2 call sites, and this change is safe for both of them: * `cmInstallTargetGenerator::Compute`: Never uses an alias target name. * `cmLocalGenerator::FindGeneratorTargetToUse`: Falls back to global lookup.

* Make message suppression more consistent.Michael Scott2015-11-301-1/+2
| | | | | | | | | | | | | | | | Make the message suppression more consistent, by adding a check for the message related CMake variables in cmake::IssueMessage, which allows callers of IssueMessage other than the message command to behave as expected. Also added a check for CMAKE_SUPPRESS_DEVELOPER_WARNINGS in the message command to mirror the deprecated message type behaviour. Added a 'force' flag to the cmake::IssueMessage method, to make the message suppression consistent, when setting the message related CMake variables directly in a CMake file. Expand message command tests to cover the AUTHOR_WARNING message type as well.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
