Use generic thread-local value for kernel/groupattrs, crash context and eventlog scope

2025-11-27T21:47:44Z

- fix StdThreadLocalImpl -- make static state refcounted, there is no guarantee that static fields will outlive threads or TThreadLocalValues; - replace thread local values to generic local storage value in some places; - call runtime Init and replace local values factory; - don't disable NCurrentThreadEventlog for ytxx runtime, it should now work; - ensure generic local storage values are allocated after runtime init; - use function-scope static variables to prevent issues with order of construction and destruction; - basesearch now almost works with coroutines (with NProfile disabled). commit_hash:7fde81591b0dbc3a53b8d1cb11bb96930a2e9a80

TThreadLocalValue over standard thread_locals

2025-11-24T22:25:22Z

Current TThreadLocal implementation doesn't destroy objects on thread exit (so we can't replace thread\_local tls value with it, and with TGenericLocalValue too), standard thread\_local values can't be class members. So try to reimplement TThreadLocalValue: - instead of adressing by thread id, address objects by uniq object id in thread\_local deque of all objects of current type; - use hashmap of all existing perthread deques to destroy objects with their TThreadLocal; - try to make object ids flat; - no complex lookup inside and no contention between tls.Get calls; - ShortLivedThreads ut now works; - some fixes in Trace ut, make threads outlive tls value; - benchmark results , looks better than all others; - probably should switch to this implementation by default and remove old. commit_hash:262ce4d363751f577373a452a0c2c84d1fe5b79c

fix tsan warnings in library/cpp/threading unit tests

2024-09-12T16:43:48Z

- blocking_counter: fix destroy order; - thread_local: Head_.load must use std::memory_order_acquire to match memory_order_release in compare_exchange and ensure all writes are visible; also fix always null node value in first compare_exchange call; - work_stealing: use atomics. commit_hash:53f01a16bb40dd3eb890b0eb60388ecb0ce9c908
