Explanation
[
#1763]DefaultTypeManagernow protects_knownTypeswith_lock, uses aConcurrentDictionaryfor name lookups, and returns a locked snapshot. However,RegisterTypeInternalassigns aliases with_knownTypesByName[td.Alias] = tdwithout checking for an existing alias or type name. Two registrations with colliding aliases, or an alias that matches another type name, silently replace the lookup mapping. A concurrentGetTypeByNamecan therefore return a descriptor for the wrong type, contrary to the issue's requirement to prevent incorrect name lookups during registration.Resolution
Validate the type name and alias keys before mutating either collection. Reject conflicting keys rather than replacing their mappings. Add tests for concurrent registrations whose aliases collide, including an alias that matches another registered type name.

- Around line 150-153: Wrap TypeManager.RegisterType in the attached-module
registration flow with a catch that removes the typeName entries from
_loadedModules and _fileHashes while holding _registrationLock, then rethrows.
Keep publishing both entries before registration so ScriptFactory cannot observe
a registered type without its module.

Просьба пояснить, зачем делается именно так
There was a problem hiding this comment.
Список типов читают без блокировки: TryGetType(Type), GetTypeByFrameworkType и IsKnownType перебирают его, а RegisteredTypes отдает наружу — Рефлектор.ИзвестныеТипы перебирает его, пока другое задание может подключать сценарий. List.Add параллельно с перебором либо падает с «Collection was modified», либо отдает null: размер увеличивается раньше, чем записан элемент, а при расширении подменяется внутренний массив.
Поэтому при регистрации собирается новый массив и подменяется ссылка: читатель один раз берет ссылку и перебирает неизменный снимок. С блокировкой на чтение RegisteredTypes все равно пришлось бы копировать на каждый вызов, а так копирование происходит только при регистрации. Регистрация редкая — на старте около 280 типов плюс подключаемые сценарии, так что копирование незаметно.
Массив обновляется раньше словаря имен, чтобы тип, найденный по имени, уже был и в списке.

Попробовал. Тип по имени ищется на каждом Новый и Тип(), и с ReaderWriterLockSlim 8 фоновых заданий, создающих объекты, замедлились в 2,5 раза (393 → 967 мс), в одном потоке на 5–8%: читатели толкаются на общем состоянии блокировки. Поэтому поиск по имени оставил без блокировки на ConcurrentDictionary, а регистрацию и редкие обращения к списку типов сделал под обычным lock. Копирование массива и порядок обновления убрал.

Мне комментарий непонятен, слишком машинный. И весь кусок кода непонятен.

Переписал проще: этот кусок убрал. Список и словарь теперь меняются под одной блокировкой, так что порядок больше не важен.

DefaultTypeManager и AttachedScriptsFactory хранили типы и модули в обычных Dictionary/List без блокировок, а регистрируют их и из фоновых заданий (ПодключитьСценарий, классы библиотек, внешние компоненты). Регистрация и список типов теперь под блокировкой, поиск типа по имени без нее: он идет на каждом Новый и Тип(). Closes EvilBeaver#1763 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Closes #1763
Типы регистрируются и во время исполнения: ПодключитьСценарий, классы библиотек, внешние компоненты — в том числе из фоновых заданий.
DefaultTypeManagerиAttachedScriptsFactoryхранили их в обычныхDictionary/Listбез блокировок: при параллельной регистрации словари портились, тип мог не находиться сразу после регистрации, а подключение одного сценария из двух заданий падало с «An item with the same key has already been added».Теперь регистрация и список типов под блокировкой, поиск по имени — без нее: он идет на каждом
НовыйиТип(). Кэш фабрик типов исправлен в #1762.🤖 Generated with Claude Code
