Sean McBride	5b23752205	Replaced incorrect double checked locking with a static Thread Sanitizer identified an incorrect implementation of double checked locking. Replaced it with a static, which therefore can only be created once.	3 years ago

Vincent Rabaud	fc28ba3156	Merge pull request #21594 from vrabaud:3.4_msan * Fix harmless MSAN error. This is similar to https://github.com/opencv/opencv/pull/21527 A macro is also created to simplify the code. * Declare fallback only once.	3 years ago

cudawarped	f66a2ffa1e	Fix GpuMat to correctly calculate dataend when using GpuMat::create(). Add output to createMat() to be used by locateROI test cases.	3 years ago
Ed Martin	dc29632d4e	Fallback to vaCreateImage + vaPutImage/vaGetImage when vaDeriveImage fails Per intel docs for libva, when vaDeriveImage fails vaCreateImage + vaPutImage should be tried. This is important as mesa with AMD HW will always fail because the image is interlaced so a indirect method must be used to get the surface to/from and image Fixes https://github.com/opencv/opencv/issues/21536	3 years ago
Vincent Rabaud	b5b52afd35	Merge pull request #21527 from vrabaud:3.4_msan * Fix wrong MSAN errors. Because Fortran is called in Lapack, MSAN does not think the memory has been written even though it is the case. MSAN does no support well cross-language memory analysis. * Make a dedicated check.	3 years ago
Vadim Levin	d88730685e	fix: submodules creation and registration - Add special case handling when submodule has the same name as parent - `PyDict_SetItemString` doesn't steal reference, so reference count should be explicitly decremented to transfer object life-time ownership - Add sanity checks for module registration input - Add Python 2 and Python 3 reference counting handling	3 years ago

pkubaj	5d9ea394ba	Fix VSX detection on FreeBSD hwcap should actually be long.	3 years ago
Yuriy Chernyshov	d1b533d399	Disable -Wreturn-type-c-linkage under clang-cl clang-cl defines both __clang__ and _MSC_VER, yet uses `#pragma GCC` to disable certain diagnostics. At the time `-Wreturn-type-c-linkage` was reported by clang-cl. This PR fixes this behavior by reordering defines.	3 years ago

dwardor	54c180092d	Merge pull request #21114 from dwardor:patch-1 * Fix compile against lapack-3.10.0 Fix compilation against lapack >= 3.9.1 and 3.10.0 while not breaking older versions OpenCVFindLAPACK.cmake & CMakeLists.txt: determine OPENCV_USE_LAPACK_PREFIX from LAPACK_VERSION hal_internal.cpp : Only apply LAPACK_FUNC to functions whose number of inputs depends on LAPACK_FORTRAN_STR_LEN in lapack >= 3.9.1 lapack_check.cpp : remove LAPACK_FUNC which is not OK as function are not used with input parameters (so lapack.h preprocessing of "LAPACK_xxxx(...)" is not applicable with lapack >= 3.9.1 If not removed lapack_check fails so LAPACK is deactivated in build (not want we want) use OCV_ prefix and don't use Global, instead generate OCV_LAPACK_FUNC depending on CMake Conditions Remove CONFIG from find_package(LAPACK) and use LAPACK_GLOBAL and LAPACK_NAME to figure out if using netlib's reference LAPACK implementation and how to #define OCV_LAPACK_FUNC(f) * Fix typos and grammar in comments	3 years ago

Vincent Rabaud	6b4ea68bc7	Solve Rect overflow issues. Fow now, it is possible to define valid rectangle for which some functions overflow (e.g. br(), ares() ...). This patch fixes the intersection operator so that it works with any rectangle.	3 years ago

Piotr Kubaj	68e425f869	Add support for runtime CPU feature check on POWER on FreeBSD. 1. Code uses PPC_FEATURE_HAS_VSX, but it's not checked similarly to PPC_FEATURE2_ARCH_3_00 and PPC_FEATURE2_ARCH_3_00 for availability. FreeBSD has those macros in machine/cpu.h, but I went with the way chosen for PPC_FEATURE2_ARCH_3_00 and PPC_FEATURE2_ARCH_3_00. Other than that, FreeBSD also has sys/auxv.h and that's where elf_aux_info() is defined. 2. getauxval() is actually Linux-only, but code checked for __unix__. It won't work on all UNIX, so change it back to __linux__. Add another code variant strictly for FreeBSD. 3. Update comment. This commit adds code for FreeBSD, but recently there appeared support for powerpc64 in OpenBSD.	3 years ago
