ydb/library/cpp/yt/misc/ya.make, branch CLI_2.32.0Mirror of YDB github reposhttps://code.mastervirt.ru/ydb/atom?h=CLI_2.32.02026-06-06T21:16:49ZCache process/thread id getters and use them in TError origin capture2026-06-06T21:16:49Zbabenkobabenko@yandex-team.com2026-06-06T20:52:00Zurn:sha1:f10c7206fb31af8057446bceef9707aabaa9456e
## Motivation
Profiling the YT master Automaton thread showed TOriginAttributes::Capture (run on every non-OK TError) spending ~60% of its time in a getpid() syscall — uncached on glibc >= 2.25. NYT::GetCurrentThreadId() (gettid) feeds hot thread-affinity / log-manager checks on the same thread.
## Changes
- New library/cpp/yt/system/process_id.* with cached GetProcessId(); GetSystemThreadId() now caches the kernel tid in TLS. Both caches reset in the child after fork.
- Moved thread_name.{h,cpp} from misc to system.
- Removed GetCurrentProcessId/GetCurrentThreadId shims from yt/yt/core/misc/proc.{h,cpp}; migrated all callers to NYT::GetProcessId / NYT::GetSystemThreadId.
- TOriginAttributes::Capture uses the cached getters; recorded Tid is now the real kernel tid (matches perf/ps).
- Added microbenchmarks (library/cpp/yt/system/benchmarks, yt/yt/core/benchmarks/error.cpp).
