* TMapOps::Value: better return typeignatloskutov2023-06-022-5/+5
| | | | | | | | Выбирается общий тип, а не тип значения в мапе (но не ссылка, потому что auto), что позволяет писать код в духе: ```cpp TMaybe<int> Foo(THashMap<long, int>& map, long key) { return map.Value(key, TMaybe<int>()); } ```

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | platform При сборке проектов с ```--sanitize=thread``` под **darwin**, по умолчанию попадет ```util``` и его часть ```system/context.h```, где в случае ```thread_sanitizer_enabled``` выставляется ```USE_UCONTEXT_CONT```, что приводит к использованию [депрекейтнутного](https://opensource.apple.com/source/libplatform/libplatform-125/include/ucontext.h.auto.html) ```<ucontext.h>``` из [macos_sdk](https://a.yandex-team.ru/arcadia/build/platform/macos_sdk/ya.make?rev=rXXXXXX#L6). Без должных изменений, сборка падает с ошибкой. ```In file included from /Users/hiddenpath/.ya/build/build_root/fnjm/000128/util/all_system_1.cpp:13: In file included from /Users/hiddenpath/arcadia/util/system/context.cpp:31: In file included from /Users/hiddenpath/arcadia/util/system/context.h:46: /Users/hiddenpath/.ya/tools/v4/2088833948/usr/include/ucontext.h:51:2: error: The deprecated ucontext routines require _XOPEN_SOURCE to be defined #error The deprecated ucontext routines require _XOPEN_SOURCE to be defined ^ In file included from /Users/hiddenpath/.ya/build/build_root/fnjm/000128/util/all_system_1.cpp:13: In file included from /Users/hiddenpath/arcadia/util/system/context.cpp:31: /Users/hiddenpath/arcadia/util/system/context.h:68:9: error: use of undeclared identifier 'getcontext' getcontext(&Ctx_); ^ /Users/hiddenpath/arcadia/util/system/context.h:72:9: error: use of undeclared identifier 'getcontext' getcontext(&Ctx_); ^ /Users/hiddenpath/arcadia/util/system/context.h:80:9: error: use of undeclared identifier 'makecontext' makecontext(&Ctx_, (ucontext_func_t)ContextTrampoLine, 1, c.TrampoLine); ^ /Users/hiddenpath/arcadia/util/system/context.h:87:9: error: use of undeclared identifier 'swapcontext' swapcontext(&Ctx_, &next->Ctx_); ^ 5 errors generated.

* charset: do not allow surrogate pairs in UTF-8dpotapov2023-01-162-14/+114
| | | | | | | | | | | | | | | | | | | By [RFC3629 section 3](https://datatracker.ietf.org/doc/html/rfc3629#section-3): ``` The definition of UTF-8 prohibits encoding character numbers between U+D800 and U+DFFF, which are reserved for use with the UTF-16 encoding form (as surrogate pairs) and do not directly represent characters. ``` Current implementation of `ReadUTF8CharAndAdvance` allows `UTF-8` encoded surrogate characters like 0xED 0xA0 0xBD or 0xED 0xB3 0x9A leaving them in the strings that cannot be processed afterwards by external programs like `iconv`. This patch provides `strict` template flag that disables this leniency. This flag is not enabled by default, because Arcadia already has hundreds of tests with inputs containing such surrogate pairs and these tests breaks in strict mode and there is a chance that prod might affected too. SSE4 implementation doesn't perform any validation at all, so it is left unchanged.

* [util] Terminate instead of deadlock after fork with running thread poolssskvor2022-11-101-4/+8
| | | | | Контекст. В древнем странном коде обнаружили, что если создавать `TThreadPool` часто и конкуретно с запуском `TShellCommand`, то иногда последняя дедлочится: если начали выполнять конструктор `TThreadPool` и регистрацию в `TAtforkQueueRestarter`, захватив `TAtforkQueueRestarter::ActionMutex`, а в другом потоке параллельно сделали `fork`, то последний может форкнуться с залоченым мьютексом. Первым делом происходит вызов коллбеков из `pthread_atfork`, где мьютекс лочится заново. Конечно, форкаться в сложных программах с тредпулами категорически запрещено, но, подозреваю, много кода в аркадии так написано. Давайте как-то защитимся от такого.

| | | `#define noexcept throw()` is a questionable idea, since replacing `noexcept` with `throw()` in expressions such as `noexcept(true)` results in spectacular compiler errors. We stopped supporting CUDA 8 (and even CUDA 9) long ago, which means we can just get rid of the problematic define.
