      Avoid using KWSys auto_ptr by adopting it ourselves · b5ec5b09
      Brad King authored
      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 \

      cmake: Add an option to control what files needs to be traced · e63151ff
      Alex Turbov authored
      Even in relatively small projects using `--trace` (and `--trace-expand`)
      may produce a lot of output.  When developing a custom module usually
      one is interested in output of only a few particular modules.
      Add a `--trace-source=<file>` option to enable tracing only a subset of
      source files.  The final output would be only from requested modules,
      ignoring anything else not matched to given filename(s).

      Remove `//------...` horizontal separator comments · 0ac18d40
      Brad King authored
      Modern editors provide plenty of ways to visually separate functions.
      Drop the explicit comments that previously served this purpose.
      Use the following command to automate the change:
          $ git ls-files -z -- \
              "*.c" "*.cc" "*.cpp" "*.cxx" "*.h" "*.hh" "*.hpp" "*.hxx" |

            egrep -z -v "^Source/cmDependsJavaParser(\.y|\.cxx|Tokens\.h)" |

            xargs -0 sed -i '/^\(\/\/---*\|\/\*---*\*\/\)$/ {d;}'

      Isolate formatted streaming blocks with clang-format off/on · 64b55203
      Brad King authored
      The clang-format tool can do a good job formatting most code, but

      Surround such blocks with the pair

      Format include directive blocks and ordering with clang-format · e1c77472
      Brad King authored
      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
            - 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 semantics · 7c36d206
      Brad King authored
      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
      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 purpose · 0e44f489

      Rename methods:
      * `cmMakefile::Find{ => LocalNonAlias}Target`

      Fix lookup of an ALIAS target outside aliased target's directory (#16044) · bc30f8b5
      Brad King authored
      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.

      Avoid occasional use-after-free when a variable watch is executed · c6104028
      Yves Frederix authored
      Re-lookup a variable value when an associated VariableWatch is executed
      in cmMakefile::GetDefinition.
      This fixes a problem with 'def' sometimes becoming invalid due to memory
      reallocation inside an std::vector. In this case, the problem was that
      if the call to VariableAccessed actually executed a callback function,
      the internal state of the makefile has changed due to the associated
      function scope being pushed. This in turn implies that a new
      cmDefinitions instance was pushed in cmMakefile::VarTree. As
      cmLinkedTree is based on an std::vector, this push can have triggered
      reallocation of its internal memory buffer. However, as the value of
      'def', which was computed on method entry, actually points to a property
      of one of the cmDefinitions instances in cmMakefile::VarTree,
      reallocation can invalidate the value of 'def' so that it cannot simply
      be returned at the end of the function. The solution implemented here is
      to simply lookup the value of 'def' again.

      Optimize cmMakefile::ExpandVariablesInStringNew. · bd2384f5
      Milian Wolff authored
      We can remove the temporary allocations required for the
      default-constructed t_lookup passed into the openstack by refactoring
      the code slightly. Furthermore, we use a vector instead of a stack,
      since the latter is based on a deque which is not required for a
      heap / lifo structure.
      This patch removes ~215k allocations.
      This hotspot was found with heaptrack.

      Added a 'force' flag to the cmake::IssueMessage method, to

      message related CMake variables directly in a CMake file.
      Expand message command tests to cover the AUTHOR_WARNING message
