Unpoison use-after-dtor access to ref counter

2026-07-17T10:21:08Z

Two scenarios addressed: - Access to ref counters after explicit destructor of an object - Access to vptr for upcast of an already destroyed object commit_hash:a8f27500111817f325832d006feb3ce6c3c830f1

YT-18571: Drop TSharedRef::FromString(const char* str)

2026-07-11T09:16:30Z

Rationale: all overloads of `TSharedRef::FromString` must remain cheap and don't copy any payload. Remove the zero-terminated C string overload of `TSharedRef::FromString`. Callers passing a string literal should use `std::string/TString` explicitly. #| || **![](https://nda.ya.ru/t/mAiQIjHx7Mm3JC =30x) Echo tests** || |# commit_hash:1a6718abcbe4e6a8f58592f55de8c37ceb2b73d3

Address-salted ref-counted signature

2026-06-27T08:28:22Z

Self-validating signature word at the head of every `TRefCounter` (`YT_ENABLE_REF_COUNTED_SIGNATURE`, on by default in debug) so a coredump walker can distinguish a live ref-counted object from freed-but-unreclaimed memory and locate the counter without virtual-base casts. Consumed by gdb_plugin (separate PR). commit_hash:6696d8c26a8298be6543b1e3456de617d06417e9

Add ExactRefCountedCast and TRef::Contains

2026-06-24T09:39:10Z

Some handy helpers. `ExactRefCountedCast(p)`: exact-type downcast for `New()`-allocated objects. `New(`) builds a final `TRefCountedWrapper`, so this casts to the wrapper and upcasts back to `T*`; being final, the `dynamic_cast` lowers to a single `type_info` compare (~2ns vs ~20ns for the is-a path). `TRef::Contains(other)`: true iff other's range lies within this range. commit_hash:138e8719b8ecbd953437b81380e54f736db029ef
