* Cross-allocator copying constructor and copy assignment operator
for concurrent_vector are deprecated.
* Added input_node to the flow graph API. It acts like a source_node
except for being inactive by default; source_node is deprecated.
* Allocator template parameter for flow graph nodes is deprecated. Set
TBB_DEPRECATED_FLOW_NODE_ALLOCATOR to 1 to avoid compilation errors.
* Flow graph preview hetero-features are deprecated.
* Fixed the task affinity mechanism to prevent unlimited memory
consumption in case the number of threads is explicitly decreased.
* Fixed memory leak related NUMA support functionality in task_arena.
OBS-URL: https://build.opensuse.org/package/show/devel:libraries:c_c++/tbb?expand=0&rev=64
* Multiple APIs are deprecated. For details, please see
Deprecated Features appendix in the TBB reference manual.
* Added C++17 deduction guides for flow graph nodes.
Preview Features
* Added isolated_task_group class that allows multiple threads to add
and execute tasks sharing the same isolation.
* Extended the flow graph API to simplify connecting nodes.
* Added erase() by heterogeneous keys for concurrent ordered containers.
* Added a possibility to suspend task execution at a specific point
and resume it later.
Bugs fixed
* Fixed the emplace() method of concurrent unordered containers to
destroy a temporary element that was not inserted.
* Fixed a bug in the merge() method of concurrent unordered
containers.
* Fixed behavior of a continue_node that follows buffering nodes.
* Added support for move-only types to tbb::parallel_pipeline
* Fixed detection of clang version when CUDA toolkit is installed
- Refresh patches:
* cmake-remove-include-path.patch
* disable-irml.patch
* optflags.patch
OBS-URL: https://build.opensuse.org/package/show/devel:libraries:c_c++/tbb?expand=0&rev=59
* Added TBBMALLOC_SET_HUGE_SIZE_THRESHOLD parameter to set the
lower bound for allocations that are not released back to OS
unless a cleanup is explicitly requested.
* Added zip_iterator::base() method to get the tuple of underlying
iterators.
* Improved async_node to never block a thread that sends a message
through its gateway.
* Extended decrement port of the tbb::flow::limiter_node to accept
messages of integral types.
* Removed the number_of_decrement_predecessors parameter from the
constructor of flow::limiter_node. To allow its usage, set
TBB_DEPRECATED_LIMITER_NODE_CONSTRUCTOR macro to 1.
* Added ordered associative containers:
concurrent_{map,multimap,set,multiset} (requires C++11).
OBS-URL: https://build.opensuse.org/package/show/devel:libraries:c_c++/tbb?expand=0&rev=55
* Added support for enqueuing tbb::task into tbb::task_arena
(https://github.com/01org/tbb/issues/116).
* Improved support for allocator propagation on concurrent_hash_map
assigning and swapping.
* Improved scalable_allocation_command cleanup operations to release
more memory buffered by the calling thread.
* Separated allocation of small and large objects into distinct memory
regions, which helps to reduce excessive memory caching inside the
TBB allocator.
- Disable python2 support
