| * Propagate backtraces from LINK_LIBRARIES through to link line itemsBrad King2020-02-101-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | Since commit d4d0dd0f6a (cmLinkLineComputer: Add ComputeLinkLibs overload with backtraces, 2019-09-13, v3.16.0-rc1~87^2~4), backtraces have been collected by `ComputeLinkLibs` by looking back through the link implementation libraries for one matching the text of the link line item. This is slow in projects with long link lines. Instead, teach `cmComputeLinkDepends` and `cmComputeLinkInformation` to carry backtrace information explicitly along with the text of each item. Fixes: #20322
* | clang-format: fix erroneous handling of header <queue>Marc Chevrier2020-01-061-2/+1
|/ | | | The rule Regex: '^<' was not applied to this header because a more specific one applies: Regex: '^(<|")Qt?[A-Z]' used for Qt headers (rules are not case-sensitive). So adding a specific rule for this header before the Qt rule is required.
* Revise include order using clang-format-6.0Kitware Robot2019-10-011-5/+6
| | | | | Run the `clang-format.bash` script to update our C and C++ code to a new include order `.clang-format`. Use `clang-format` version 6.0.
* cmComputeLinkDepends: remove manual memory deallocationTushar Maheshwari2019-09-181-1/+2
| | | | | - Replace owning raw `DependSetList` pointer with direct object. - Use an extra `bool Initialized` flag to imitate `nullptr` semantics.
* clang-tidy: Replace typedef with usingRegina Pfeifer2019-09-031-4/+4

* IWYU: Fix handling of <memory> standard headerBrad King2019-07-101-0/+1
| | | | | | | | An old workaround for `std::allocator_traits<>::value_type` lints from IWYU on `std::vector<>` usage breaks IWYU's handling of `<memory>`. Convert the workaround to use the same approach we already use for a workaround of `std::__decay_and_strip<>::::__type` lints. Then update the `<memory>` inclusions to follow the now-correct IWYU lints.
* modermize: replace some raw pointers w/ `unique_ptr`Alex Turbov2019-06-241-1/+1
|
* Delete some default constructors and assignment operatorsAlbert Astals Cid2019-02-151-0/+3
| | | | | | They are unused, but if someone used them they would lead to problems since they would copy the internal raw pointers and the destructor would cause double delete
* cleanup: Prefer compiler provided special member functionsRegina Pfeifer2019-01-251-2/+0
|
* clang-tidy: Use `= default`Regina Pfeifer2019-01-251-8/+2
| | | | | | Suppress some cases in `Source/cmGeneratorExpressionNode.cxx` and `Source/cmUVHandlePtr.h` where a few older compilers require a user-defined default constructor (with `{}`).

* clang-tidy: Remove redundant member initializationsRegina Pfeifer2018-12-151-2/+1

* Fix dependency propagation through same-name imported targetsBrad King2018-09-071-3/+3
| | | | | | | | | | If two imported targets in different directories have the same name we should still be able to propagate transitive link dependencies from both. Fix the target and link dependency analyzers to de-duplicate targets using target pointers rather than target names since the pointers will not be duplicated even if the names are. Issue: #18345
* cmLinkItem: Convert to a "sum type" over a string and target pointerBrad King2018-09-071-2/+1
| | | | | | | | | Avoid exposing the item name implicitly as std::string. When the item is a target, avoid storing a second copy of its name. Most link item construction is paired with calls to `FindTargetToLink` to get the possible target pointer. Rename these methods to `ResolveLinkItem` and refactor them to construct the entire item.

* 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.

| | | | | | | | | | | | | 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 King2016-04-291-1/+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 King2016-04-291-1/+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.
* Remove some obsolete declarationsStephen Kelly2015-10-271-1/+0
| | | | | | | | | | | | | Ensure that cmStandardIncludes.h is included before any platform header in cmGeneratorExpressionEvaluator.h. That file needs to change as a result of removal of the cmMakefile.h header from cmGeneratorExpressionNode.h, affecting the compilation of cmGeneratorExpressionNode.cxx. On AIX we need to include our own headers first to get large file support macros defined consistently within system headers. The old order in this header worked only because it was always included after other headers.

* cmTarget: Lookup targets in LinkInterface and LinkImplementationBrad King2014-06-231-5/+5
| | | | | | | | | | | | | | | Instead of storing just the string names in these structures, lookup any target associated with each item and store its cmTarget pointer. Use the cmLinkItem class to hold the name and pointer together. Update client sites to use the pre-stored lookup result instead of looking up the target name again. Create a cmTarget::LookupLinkItems helper method to handle the lookup. Since lookups are now moving from cmComputeLinkDepends::AddLinkEntries to cmTarget::LookupLinkItems, move use of CheckCMP0004 to the latter. This drops use of CheckCMP0004 from entries added for _LIB_DEPENDS variables by cmComputeLinkDepends::AddVarLinkEntries, but I do not think that use was intentional originally anyway.
* cmComputeLinkInformation: Remove 'head' argumentBrad King2014-06-231-3/+1
| | | | | | It is only ever constructed with the current target as its own 'head'. Co-Author: Stephen Kelly <steveire@gmail.com>
* stringapi: Pass configuration names as stringsBen Boeckel2014-03-081-2/+3
|
* strings: Remove cmStdString referencesBen Boeckel2014-03-081-2/+2
| | | | | | | | | | | 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.

* cmTarget: Make GetProperty() const.Stephen Kelly2013-10-311-3/+4
| | | | | | This has follow-on effects for other methods and classes. Further work on making the use of const cmTarget pointers common can be done, particularly with a view to generate-time methods.
* Make linking APIs aware of 'head' targetStephen Kelly2013-01-081-1/+2
| | | | | | | | | | | The 'head' is the dependent target to be linked with the current target. It will be used to evaluate generator expressions with proper handling of mapped configurations and is used as the source target of properties. This requires that memoization is done with a key of a pair of target and config, instead of just config, because now the result also depends on the target. Removing the memoization entirely is not an option because it slows cmake down considerably.
* Tolerate cycles in shared library link interfaces (#12647)Brad King2012-01-131-0/+4
| | | | | | | | | | | | | Since commit 183b9509 (Follow all dependencies of shared library private dependencies, 2011-12-14) we honor LINK_INTERFACE_LIBRARIES when following dependent shared libraries. The link interface properties may form a cycle if set incorrectly by a project. Furthermore, the property LINK_DEPENDENT_LIBRARIES may form a cycle if set incorrectly by hand (though CMake should never generate one). In either case, do not follow the cycle forever when following the dependent shared library closure. We only need to add dependency edges to the constraint graph once. Add "LinkInterfaceLoop" test to cover this case.
* Split notion of node lists and edge listsBrad King2010-08-251-0/+1

* Convert CMake to OSI-approved BSD LicenseBrad King2009-09-281-14/+9
| | | | | | | 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.
* Define 'multiplicity' for cyclic dependenciesBrad King2009-09-011-0/+1
| | | | | | | | | We create target property "LINK_INTERFACE_MULTIPLICITY" and a per-config version "LINK_INTERFACE_MULTIPLICITY_<CONFIG>". It sets the number of times a linker should scan through a mutually dependent group of static libraries. The largest value of this property on any target in the group is used. This will help projects link even for extreme cases of cyclic inter-target dependencies.
