NightOwl888 opened a new pull request #441: URL: https://github.com/apache/lucenenet/pull/441
Combined with #439, this closes #417. This review included the following collections: - `LurchTable<TKey, TValue>` - `ConcurrentDictionary<TKey, TValue>` - `ConcurrentQueue<T>` - `ConcurrentStack<T>` - `ConcurrentBag<T>` - `BlockingCollection<T>` With the exception of `FieldCacheImpl`, all access to these collections were checked to ensure proper use. Locks were added in cases where they were missing, and collections were swapped for non-synchronized versions in cases where there was no reason to use one. There are a few places we use `ConcurrentDictionary<TKey, TValue>` just to take advantage of the fact that its enumerator allows modification of the collection without throwing an exception. `FEATURE_DICTIONARY_REMOVE_CONTINUEENUMERATION` was added so we will be able to use `Dictionary<TKey, TValue>` in .NET 5.x+ because it now supports modification during enumeration also. There were a few bugs found and fixed with `GetOrAdd` method calls and one found in the `LuceneTestCase` class (the base class for all tests in the TestFramework) which replaced the collection with a concurrent one, but didn't take into account the other related code that was inside of the lock that was removed. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
