Priority: ➖ Normal Estimated code review effort: 3 (Moderate) | ~20 minutes Change: Bug fix Suggested reviewers: Merge Risk: 🟡 Moderate · up to A library that waits for a background compilation can hang indefinitely, and the new test may not detect a failure of simultaneous loading. Address the lock-held callback before merging. Security Architecture ReviewSecurity architecture risk: 🟡 Moderate · up to The shared lock addresses inconsistent global-name lookup, but it also lets a library loader stall unrelated compilation and global-property access in the same runtime. A loader that waits for a background job needing that lock can deadlock indefinitely. The exposure depends on which scripts and libraries the host permits and which workloads share a runtime.

69-74: 🎯 Functional Correctness | 🔵 Trivial | ⚡ Quick winAdd a participation assertion to the concurrency test.
The worker threads can remain before their first compilation until the registration loop finishes. The test can then stop and join all workers, and
errors.Should().BeEmpty()can pass without any compilation overlapping registration. Add a startup or progress signal and assert that at least one compilation occurred before registration completed.This is a test-coverage improvement, not a production defect.

Это костыль. Данная коллекция это просто коллекция. Она не конкурентная. Если нужен ее конкурентный вариант, надо создать другой класс.

Согласен, флаг из коллекции убрал.

Мне все это не нравится. Компиляция это однопоточный изолированный процесс. Если компиляции одновременно будут модифицировать глобальное пространство имен это потом все на рантайме попадает, когда SymbolBinding полученного модуля не совпадут с тем, что в рантайме

Согласен, переделал: компиляция и изменения глобального пространства имен (#Использовать, ПодключитьВнешнююКомпоненту) теперь идут под одной блокировкой движка, по одной за раз. Конкурентные коллекции и копии таблицы убрал.

Компилятор искал глобальные имена в общей таблице окружения без блокировки, а #Использовать и ПодключитьВнешнююКомпоненту в другом потоке в это время дописывали в нее имена, и компиляция падала с ложным «Неизвестный символ». Теперь компиляция по общей таблице и ее изменения идут под одной блокировкой на самой таблице, по одной за раз. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Компилятор ищет глобальные имена в общей таблице окружения, а первое
#Использоватьбиблиотеки, глобальные перечисления компоненты иПодключитьВнешнююКомпонентув это время дописывают туда имена и области. Пока словарь имен перестраивается, поиск не находит давно зарегистрированное имя, и сценарий, который компилируется в соседнем задании или запросе, падает с ложным «Неизвестный символ».Теперь компиляция по общей таблице и любые изменения таблицы идут под одной блокировкой на самой таблице, по одной за раз. Блокировка реентерабельная:
#Использоватьвнутри компиляции компилирует модули библиотеки в том же потоке.Компиляции в разных потоках теперь идут по очереди: 8 заданий, которые только компилируют, работают в 2,5 раза медленнее, в одном потоке разницы нет. Если тело модуля библиотеки при загрузке ждет фоновое задание, которое само компилирует или подключает компоненту, оба потока встанут.
Тест
GlobalSymbolsThreadSafetyTestsв Core.Tests, без исправления падает. Заодно уходит гонка параллельной загрузки одной библиотеки из #1768: библиотеки грузятся только во время компиляции. Тест оттуда перенесен.🤖 Generated with Claude Code
