* Refactor: Modernize `cmVariableWatchCommand` a littleAlex Turbov2019-10-171-7/+7
|
* clang-tidy: modernize-use-autoRegina Pfeifer2019-09-101-2/+1
| | | | | | Set the MinTypeNameLength option to an impossibly high value in order to limit the diagnostics to iterators. Leave new expressions and cast expressions for later.
* clang-tidy: Use `= default`Regina Pfeifer2019-01-251-6/+2
| | | | | | Suppress some cases in `Source/cmGeneratorExpressionNode.cxx` and `Source/cmUVHandlePtr.h` where a few older compilers require a user-defined default constructor (with `{}`).
* variable_watch: Made it safe to add/remove watches in access callbacksJustin Berger2017-09-211-19/+16

* Meta: modernize old-fashioned loops to range-based `for`.Pavel Solodovnikov2017-09-121-8/+5
| | | | | | Changes done via `clang-tidy` with some manual fine-tuning for the variable naming and `auto` type deduction where appropriate.
* Use quotes for non-system includesDaniel Pfeifer2017-04-111-1/+1
| | | | | | | | | | | | | Automate with: git grep -l '#include <cm_' -- Source \ | xargs sed -i 's/#include <\(cm_.*\)>/#include "\1"/g' git grep -l '#include <cmsys/' -- Source \ | xargs sed -i 's/#include <\(cmsys\/.*\)>/#include "\1"/g' git grep -l '#include <cm[A-Z]' -- Source \ | xargs sed -i 's/#include <\(cm[A-Z].*\)>/#include "\1"/g'
* 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copyright/license notice headers that spell out copyright holder names and years are hard to maintain and often out-of-date or plain wrong.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 King2016-06-291-2/+2
| | | | | | | | | | | | 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|'
* cmVariableWatch: Fix potential memory leakBrad King2016-05-251-2/+4
| | | | | Teach cmVariableWatch::AddWatch to own the Pair it allocates until it needs to pass ownership to WatchMap.
* Revise C++ coding style using clang-formatKitware Robot2016-05-161-45/+29
| | | | | | | | | | | | | 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.
* Avoid occasional use-after-free when a variable watch is executedYves Frederix2016-03-231-1/+3
| | | | | | | | | | | | | | | | | | | 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.

* variable_watch: Remove undocumented and redundant access typeBen Boeckel2014-05-221-1/+0
| | | | | | The ALLOWED_UNKNOWN_VARIABLE_READ_ACCESS access type was switched on an undocumented variable and its lookup caused an unnecessary performance impact. Remove it.
* variable_watch: Prevent making extra entries in the watch mapBen Boeckel2013-08-081-0/+4
| | | | | | | When removing a watch on a variable, using the operator [] on the internal map will create an empty watch if the variable doesn't have any existing watches. Rather than creating this empty structure in the map, return if there isn't a watch on the variable already.
* variable_watch: Allow specifying the data to match in RemoveWatchBen Boeckel2013-08-081-2/+6
| | | | | Now that watches are dependent on their client_data when adding, it also makes sense to allow matching the data for removal.
* variable_watch: Match client_data when finding duplicatesBen Boeckel2013-08-081-5/+6
| | | | | | | | | If a callback has the same data as another call, we don't want to delete the old callback. This is because if the client_data is the same, it might get deleted causing the new client_data to be bogus. Now, AddWatch will return true if it will use the watch, false otherwise. Callers should check the return value to know whether client_data was adopted by the watch or not.
* variable_watch: Add a deleter for the client dataBen Boeckel2013-08-081-1/+3
| | | | | | The client data is arbitrary and the callback may be called an unspecified number of times, so the cmVariableWatch must be the one to delete the client data in the end (if it is needed at all).
* variable_watch: Store client data as pointersBen Boeckel2013-08-081-6/+21
| | | | | The STL containers create extra copies which makes keeping track of the owner of the client data much messier.
* variable_watch: Add missing string enumeration entry (#14188)Yichao Yu2013-06-031-0/+1
| | | | | | | | In commit 9a5b4eba (All variable accesses should produce watch callbacks, 2007-05-17) we added a new enumeration value but did not update the list of strings matching them. Add the missing entry. Without this, variable_watch prints REMOVED_ACCESS instead of MODIFIED_ACCESS when set the value of the variable.
* Remove trailing whitespace from most CMake and C/C++ codeKitware Robot2012-08-131-4/+4
| | | | | | | | | | | | | | | | | 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.
