Viktor Lofgren f15dd06473 (index) Delayed close() of SearchIndexReader ... This avoids concurrent access errors. This is especially important when using Unsafe-based LongArrays, since we have concurrent access to the underlying memory-mapped file. If pull the rug from under the caller by closing the file, we'll get a SIGSEGV. Even with a "safe" MemorySegment, we'll get ugly stacktraces if we close the file while a thread is still accessing it. So we spin up a thread that sleeps for a minute before actually unmapping the file, allowing any ongoing requests to wrap up. This is 100% a hack, but it lets us get away with doing this without adding locks to the index readers. Since this is "just" mmapped data, and this operation happens optimistically once a month, it should be safe if the call gets lost.		2024-01-23 11:08:41 +01:00
