Проблема
Сервис статуса ADCM хранит токены аутентифицированных пользователей в обычном Go-отображении (map). HTTP-запросы обрабатываются параллельно, поэтому несколько запросов могут одновременно читать и записывать в это отображение.
Это может вызвать гонку данных (data race) или привести к завершению работы сервиса статуса с ошибкой:
fatal error: concurrent map read and map writeКэш токенов теперь защищён с помощью
sync.RWMutex. Добавлен регрессионный тест на корректность работы в конкурентной среде.Влияние на другие продукты
Другие продукты не затронуты. Проблема и исправление изолированы в сервисе статуса ADCM на Go и не меняют его API или внешнее поведение.
