* Remove unnecessary c_str() callsVitaly Stakhovsky2018-09-051-2/+2
| | | | Use the new IsOn(),IsOff() overloads.
* Autogen: Add CMAKE_AUTOGEN_VERBOSE variable supportSebastian Holtermann2018-06-211-3/+19
| | | | | Setting CMAKE_AUTOGEN_VERBOSE enables verbose output during AUTOMOC, AUTOUIC and AUTORCC generation.
* Revise C++ coding style using clang-format-6.0Kitware Robot2018-06-011-1/+1
| | | | | | | | | | | | Run the `clang-format.bash` script to update all our C and C++ code to a new style defined by `.clang-format`. Use `clang-format` version 6.0. * 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.
* Autogen: Add lock file to AUTORCC commandsSebastian Holtermann2018-05-301-2/+3
| | | | | By using a per .qrc lock file in AUTORCC, the same `cmake -E cmake_autorcc ...` command can be called concurrently.

| * Autogen: Use std::istreambuf_iterator for file so string readingSebastian Holtermann2018-04-031-20/+29
| | | | | | | | | | | | | | This adds a dedicated mutex for file reading and writing to cmQtAutoGenerator::FileSystem. The purpose of the change is to avoid that long files reads block cmsys based path computations, which are protected by an other mutex.

* | cmake_minimum_required: Optionally set policies with version rangeBrad King2018-03-211-1/+1
|/ | | | | | | | Teach `cmake_minimum_required` and `cmake_policy(VERSION)` to support a version range of the form `<min>[...<max>]`. Define this to mean that version `<min>` is required, but known policies up to those introduced by `<max>` will be set to `NEW`. This will allow projects to easily specify a range of versions for which they have been updated.
* Autogen: Check if a file is empty before reading itSebastian Holtermann2018-03-061-11/+18
| | | | | | | | | | | Calling `std::string::front()` on an empty string results in an undefined behavior by the C++ standard. In gcc8 it causes an assertion to fail. This adds a check to `AUTOGEN` if a file to read is empty and in case avoids the use of an empty `std::string` buffer. Closes #17793
* Autogen: Process files concurrently in AUTOMOC and AUTOUICSebastian Holtermann2018-01-171-179/+490
| | | | | | | | | | | | | | | | | | | | | | This introduces concurrent thread processing in the `_autogen` target wich processes AUTOMOC and AUTOUIC. Source file parsing is distributed among the threads by using a job queue from which the threads pull new parse jobs. Each thread might start an independent ``moc`` or ``uic`` process. Altogether this roughly speeds up the AUTOMOC and AUTOUIC build process by the number of physical CPUs on the host system. The exact number of threads to start in the `_autogen` target is controlled by the new AUTOGEN_PARALLEL target property which is initialized by the new CMAKE_AUTOGEN_PARALLEL variable. If AUTOGEN_PARALLEL is empty or unset (which is the default) the thread count is set to the number of physical CPUs on the host system. The AUTOMOC/AUTOUIC generator and the AUTORCC generator are refactored to use a libuv loop internally. Closes #17422.
* Autogen: Fix for problematic nested lists separatorSebastian Holtermann2017-12-181-0/+3
| | | | | | | | | | | | | | | In the AutogenInfo.cmake file the separator for nested lists was `@LSEP@` which led to a speed regression because the `@` character triggered an (unsuccessful) expression evaluation. By setting the policy version of the CMake instance in the `_autogen` target to 3.9, the OLD `@` evaluating behavior controlled by policy CMP0053 is disabled. Also the nested lists separator string is changed to `<<<S>>>`, which solves the problem twofold. Closes #17570
* Autogen: Add and use cmQtAutoGenerator base classSebastian Holtermann2017-11-191-0/+320
Adds the new base class `cmQtAutoGenerator` which contains common variables and methods used by `cmQtAutoGeneratorMocUic` and `cmQtAutoGeneratorRcc`.
