| | | | | Добавляем `TMultiHashMap::node_allocator_type` по аналогии с [THashMap::node_allocator_type](https://a.yandex-team.ru/arcadia/util/generic/hash.h?rev=rXXXXXX#L19), чтобы вычислять объем занимаемой памяти объектов `TMultiHashMap`. commit_hash:49c8bbcd57ac8292ff1fffa7b59e45fdd88c3278
* [util] the THashSet::operator== must compare elements using their comparison ↵swarmer2025-06-083-9/+111
| | | | | | | | | | | | | operators. The C++ standard describes the requirements for comparing unordered containers in [unord.req.general]: > Two unordered containers a and b compare equal if a.size() == b.size() and, > for every equivalent-key group [Ea1, Ea2) obtained from a.equal_range(Ea1), > there exists an equivalent-key group [Eb1, Eb2) obtained from b.equal_range(Ea1), > such that is_permutation(Ea1, Ea2, Eb1, Eb2) returns true. THashSet should use the same comparison logic. commit_hash:b897cd7387d275324bb22268d0be79da4e74bf16

| | | | | | | | | Было: при добавлении-удалении обьекта берем мьютекс, молимся чтобы тот не оказался залочен при форке, никак перед форком на лок не смотрим Помимо того что это просто не очень надежно, оно не всегда работает. Может случиться так что с мьютексом все нормально, но IntrusiveList все равно [скорапчен](HIDDEN_URL и список закольцован не там где надо (по всей видимости cpu reorder на apple m1 ехидничает). Стало: берем спинлок вместо мьютекса, в том числе берем его на время форка. commit_hash:94145ab392390a2c0b9f885275302082524606b2

* Add an option to disable the fork aware mode for TThreadPoolandybg2025-03-282-2/+14
| | | | | | | | | | | | | Продолжение починки крэшей при форке Ситуация такая же - используем subprocess для обработки данных ( subprocess не наши, написаны множеством команд на нескольких языках под конкретные ситуации), быстро избавиться от форка не получится. Есть шанс избавиться от этого пул треда, но тоже не быстро. Предлагается простое решение - не вызывать `TAtforkQueueRestarter::Get()`совсем, тогда не будет создание singletonа и вызова `pthread_atfork`. Все это под опцией `SetForkAware` - кто хочет может ее включать, для всех остальных ничего не изменится. Полная обратная совместимость, фикс ничего не мог зацепить. Проверил локально, вызова `pthread_atfork` нет в `unified agent` больше. Тесты на это очень сложно написать, без больших изменений в тред пуле, пробовал с перехватом `pthread_atfork`, к сожалении, не только `TAtforkQueueRestarter` им пользуется и нормально перехватить тоже не получилось. commit_hash:3711c6175ca64564f31f811ee1308d70ef6eb5e3

* remove Y_STRING_LIFETIME_BOUNDtazjin2025-03-121-18/+0
| | | | | | | This macro was previously used to conditionally toggle `lifetimebound` for `TString`-related functions which took its copy-on-write behaviour into account. As of rXXXXXX this is no longer used. commit_hash:93ac110d46ffbe59751c2cecc685b9838bba42b4
* check lifetimes of TStringBuf constructed from TString without taking into ↵swarmer2025-03-111-1/+1
| | | | | | | | | | | | | account copy-on-write semantics `TString` is a copy-on-write type, which means that in some cases the valid lifetime of its data might extend beyond the lifetime of an individual `TString` (if it was copied). However, there are practically no cases where this behaviour is appropriate, and leaving around an "owning" `TString` is undesirable. Due to this behaviour we have previously refrained from enabling `[[clang::lifetimebound]]` for `TStringBuf` constructors, because some cases of view construction from a temporary `TString` were in fact valid. This commit enables the check, as all existing related bugs in Arcadia have been fixed. Please see the related ticket and the announcement on Этушка (link will be in the post-commit comments) for more information. commit_hash:b2b6831ac3106a4e76064b85ec2d748b415ed67c
