* clang-tidy: Replace typedef with usingRegina Pfeifer2019-09-041-1/+1
| | | | | | | | Automate the conversion with perl -i -0pe 's/typedef ([^;]*) ([^ ]+);/using $2 = $1;/g' then manually fix a few places.
* cmDepends: Define DependencyMap instead of DependencyVectorSebastian Holtermann2019-03-271-8/+7
| | | | | | | | | | | | | In `cmDepends` use `typedef std::map<std::string, std::vector<std::string>> DependencyMap` instead of defining a `class DependencyVector : public std::vector<std::string>` and using it in `std::map<std::string, DependencyVector>`. Since `std::map<std::string, std::vector<std::string>>` is used in various other places, we now reuse all of it's auto generated methods. This doesn't happen when we use `DependencyVector` in a `std::map`, because it is a different class than `std::vector<std::string>`.
* cmDepends: Refactor cmDepends::CheckDependencies methodSebastian Holtermann2019-03-271-5/+0
| | | | | | | | | | | This patch changes the following issues in `cmDepends::CheckDependencies`: - Use the `std::string` based `std::getline` interface to read lines from a file instead of using raw reads into raw buffers. - To reduce the file system access, we load file times only once from `cmFileTimeCache` and keep them on the stack for later comparison. - When a file is removed from the file system we remove it from the `cmFileTimeCache` as well.

* Rename cmFileTimeComparison to cmFileTimeCacheSebastian Holtermann2019-03-181-6/+3
| | | | | The name `cmFileTimeCache` reflects the functionality of the class more appropriately.

* cmDepends: all members accept std::string argumentsVitaly Stakhovsky2019-01-191-5/+8
| | | | | | Most `const char*` arguments converted to `const std::string&` in `cmDepends` and derived classes. In addition performed minor code cleanup.
* clang-tidy: Use default member initializationRegina Pfeifer2018-12-151-3/+3

* cmDepends: Remove attempt to change directory that always failsCraig Scott2018-03-081-6/+0
| | | | | | | Nothing ever set `CompileDirectory` except `SetDirectory()`, but nothing ever called that function. Therefore, `CompileDirectory` was always empty for the attempt to change directory in `Check()`, which therefore would always fail. Nothing was checking the result and the code was always going to have no effect.
* IWYU: Mark cmConfigure.h with pragma: keepDaniel Pfeifer2017-08-261-1/+1

* 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.
* Remove extra semicolons from C++ code.Stephen Kelly2014-04-031-1/+1
| | | | | Clang based tools running over the code complain about these, but clang has a fixit for removing them.

* cmDepends: allow multiple dependees per dependerAlex Neundorf2012-11-061-2/+4
| | | | | | | | | | | | | | | | | | | | | This patch is heavily inspired by Michael Wild. The interfaces cmDepends::Write and cmDepends::WriteDependencies where extended to allow multiple dependees (sources) per depender (object). cmDepends::Write first collect all dependencies into a std::set before passing it to cmDepends::WriteDependencies. cmDependsC::WriteDependencies also first collects all explicit and implicit dependencies into a std::set and only then writes depend.{internal,make}. The implementation of cmDependsFortran simply loops over all sources and proceeds as before, whereas the cmDependsJava implementation is as trivial as before. This is for preventing exponential growth of depend.{internal,make} in the next commit which fixes dependency-vector erasure in cmDepends::CheckDependencies.

* fix #13474: also rescan dependencies if the depender does not existAlex Neundorf2012-08-171-0/+1
| | | | | | | | If the depender (e.g. foo.o) does not exist, also rescan dependencies if one of the dependees (e.g. foo.cxx) is older than the already existing depend.internal file, since this means it can be out of date. Alex
* Remove trailing whitespace from most CMake and C/C++ codeKitware Robot2012-08-131-3/+3
| | | | | | | | | | | | | | | | | Our Git commit hooks disallow modification or addition of lines with trailing whitespace. Wipe out all remnants of trailing whitespace everywhere except third-party code. Run the following shell code: git ls-files -z -- \ bootstrap doxygen.config '*.readme' \ '*.c' '*.cmake' '*.cpp' '*.cxx' \ '*.el' '*.f' '*.f90' '*.h' '*.in' '*.in.l' '*.java' \ '*.mm' '*.pike' '*.py' '*.txt' '*.vim' | egrep -z -v '^(Utilities/cm|Source/(kwsys|CursesDialog/form)/)' | egrep -z -v '^(Modules/CPack\..*\.in)' | xargs -0 sed -i 's/ \+$//'
* 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.
* Major optimization of C/C++ dependency scanning.Alexander Neundorf2009-09-231-4/+9
| | | | | | | | | | | | | | Now only the dependencies for the file where the dependencies actually may have changed are rescanned, before that this was done for all source files even if only one source file had changed. This reduces e.g. on my machine the time for scanning the dependencies of kdelibs/khtml/ when only one file (khtml_global.cpp) has changed from around 7.5 seconds to 1.2 seconds. The tests succeed, it does what I expected it to do on kdelibs, and Brad also reviewed the patch, so I think it should be ok. Alex

Several previous changes added more and more information for use by the dependency scanner and it was converging to having the full local generator anyway.
