An alternative approach to fixing MMapDirectory, via a DrainReclaimer class.

Description

This is an alternative approach to #1361, as a stacked PR on top of that for comparison. Much of the underlying work is the same, but this fixes the dilemma of risking AVEs vs non-deterministic GC cleanup.

First, some benchmarks:

Design	MMap parallel	req/s	MMap serial	req/s	vs SimpleFS (parallel)	vs Beta 17 MMap (parallel)
beta17 (4.8.0-beta00017)	460.49s	217	7.86s	12,722	260x slower	(n/a)
finalizer (mmap-redesign)	0.64s	156,000	3.38s	29,600	2.8x faster	720x faster
drain reclaimer (mmap-reclaimer)	0.68s	149,000	3.84s	26,100	2.6x faster	677x faster

(Note that I have a different machine than the prior benchmarks in #1151, but this was modeled in the same way. This new machine has more cores, and thus performs even worse under heavy concurrent load for beta 17.)

This branch/approach has a very small performance penalty compared to #1361, but allows for deterministic cleanup (does not rely on GC/finalizers), and does not have AVE risk either.

Core Idea

The core idea of this PR is that it uses a "drain reclaimer" to track entries and exits around raw memory access. When the parent requests closure, if any readers are mid-read, it will spin-wait until all readers have exited before reclaiming the memory. This is how it prevents AVEs at the readers. The Enter/Exit calls are around short critical regions that are not expected to throw or hang, but could theoretically be de-scheduled by the OS under heavy multitasking contention. The spin-wait will spin for a few cycles then yield to allow the OS to clear the threads. This is analogous to Lucene 10.x's behavior.

This is implemented via volatile reads/writes to be lock-free. This results in very good performance, only a minimal penalty compared to the other PR which lacks these checks.

Other Ideas Explored

To get here, I first explored the JDK FFM API to understand how it was implemented. I thought that maybe we could re-implement the API in .NET, but that is not really possible, since it requires a HotSpot feature that checks stack traces for "scoped" regions.

This wasn't a dead-end, though. Through extensive conversation with Claude Code, it made me learn about a technique called Epoch-Based Reclamation. This allows for lock-free reclamation of protected resources like raw memory access across concurrent threads. I prototyped this, but it wasn't quite right: it is more for longer-lived protection than a single IndexInput.

This then brought me to the idea of Hazard Pointers, which is almost identical to what this PR is, the only difference is that with a HP, the HP owns the pointer, whereas here the DrainReclaimer just does the bookkeeping of concurrent access, and the pointer is owned by the chunk. But it's very close in theory to Hazard Pointers, and operates much in the same way. I called this type DrainReclaimer since it isn't a true HP.

…ache#1151

…ss slices - Move MemoryMappedViewAccessorIndexInput into MMapDirectory.cs as the internal nested MMapIndexInput class, per the repo convention of not adding new files in Lucene-derived directories. - Replace the slicer's manual dispose loop with IOUtils.DisposeWhileHandlingException. - Share one MemoryMappedFile + chunk array per file per MMapDirectory instance via a refcounted SharedMapping tracked in a ConcurrentDictionary<string, Lazy<SharedMapping>>. OpenInput, CreateSlicer, its slices, and clones all piggyback on the same underlying mapping; the mapping is torn down when the last referrer disposes. - Use bufferSize: 1 + RandomAccess | Asynchronous on all FileStream creations since MemoryMappedFile bypasses the FileStream buffer. - Add a FEATURE_CONCURRENTDICTIONARY_TRYREMOVE_KEYVALUEPAIR gate and a polyfill in Support/ConcurrentDictionaryExtensions.cs for target frameworks predating .NET 5, where the TryRemove(KeyValuePair) overload is unavailable. - Add TestSharedMappingLifecycle covering the end-to-end lifecycle of the shared mapping across OpenInput, slicer, slices, and clones.

Upstream Java's MMapDirectory.map allocates nrBuffers = floor + 1 and tolerates a final 0-byte ByteBuffer at `buffers[N]`. That sentinel exists because ByteBufferIndexInput's read loop unconditionally advances its buffer cursor past the end of each buffer, so indexing `buffers[N]` must remain valid after reading the last byte of a file whose length is a whole multiple of chunkSize. Our ReadInternal bounds-checks `pos + len` before indexing and only advances `chunkIdx` while `len > 0`, so no sentinel is needed. Also, MemoryMappedFile.CreateViewAccessor rejects a zero-length view, which would force a special-case code path anyway. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

Each OpenInput/CreateSlicer now creates a fresh SharedMapping rather than sharing one via a per-file ConcurrentDictionary cache. Matches upstream Java Lucene 4.8.1 (fresh FileChannel.map() per openInput) and fixes the stale-length divergence where a second OpenInput after a file grew on disk would observe the cached length. Removes _mappings, AcquireMapping/ReleaseMapping, Lazy<SharedMapping>, and SharedMapping's refcount (TryAcquire/Release). Ownership becomes a simple ownsMapping bool passed at MMapIndexInput construction; only root instances and slicers dispose the underlying mapping. Adds three tests covering snapshot-at-open semantics, second-open- after-growth, and reopen-after-cache-drained — confirmed to match upstream Java behavior via a Maven repro against lucene-core 4.8.1. Benchmarked against the cached design and upstream Java (BDN on .NET 10, JMH on JDK 8): no-cache is within noise on 5/6 benchmarks; the only measurable cost is ~250 us over 100 sequential opens of the same file at 64 MB, a synthetic workload Lucene callers don't hit.

…ointers Rewrites the inner IndexInput to derive directly from IndexInput rather than BufferedIndexInput, and to read straight from cached raw pointers obtained once per chunk via SafeBuffer.AcquirePointer. ReadByte / ReadInt16 / ReadInt32 / ReadInt64 become single-bounds- check fast paths with no managed-buffer indirection; ReadVInt32, ReadVInt64, ReadString, etc. inherit from DataInput and call our fast ReadByte, so they pick up the speedup automatically. This mirrors upstream Java's ByteBufferIndexInput, which also derives directly from IndexInput. Per-chunk concurrency now uses a rent count + closed flag packed into a single int. A reader holds a "rent" on the chunk for as long as it caches that chunk's pointer (between chunk crossings, or until Seek / Dispose). Chunk.Close flips the closed bit immediately, but the actual ReleasePointer + accessor.Dispose is deferred until every outstanding rent has been released. This is the lazy-unmap pattern: Close never blocks, no SpinWait, and AccessViolationExceptions are structurally impossible because UnmapViewOfFile / munmap can't run while any rent is outstanding — fixing apache#1013 by construction rather than by retry. The fast path stores a precomputed `readBase` pointer (chunkBasePtr + baseOffset - chunkFileStart) so the hot-path load is a single *(readBase + pos) with no extra adds. ReadBytes uses Unsafe.CopyBlockUnaligned with a chunk-crossing loop. Cross-thread Dispose (slicer.Dispose tearing down slices being read on other threads — the apache#1013 scenario) clears currentEnd to 0 from any thread; the reader's next call falls into the slow path, observes the closed state, releases its own rent on its own thread, and throws AlreadyClosedException. Adds extensive unit tests in TestMultiMMap covering chunk-boundary crossings for every read entry point (ReadByte, ReadInt16/32/64, ReadVInt32/64, ReadBytes, Seek, SkipBytes), cross-thread Dispose during reads, post-X-thread-dispose read paths, slicer-Dispose-while- slices-being-read, double-dispose idempotency, sliced reads with non- zero base offsets across chunk boundaries, EOF at exact length, and zero-length file handling.

Final pre-merge review pass. Four small changes plus matching tests: - Drop unused Chunk.IsClosed property. Was only referenced by stale comments from an earlier design; no callers in source or tests. - Use Interlocked.Exchange instead of Volatile.Write to clear currentEnd from the cross-thread Dispose path. Lucene.NET still targets net462, where 64-bit writes can tear on 32-bit x86. The rent keeps the mapping alive so a torn write isn't a memory-safety bug, but it could let a disposed reader return one extra byte before throwing on the next call. Interlocked.Exchange is atomic on every supported runtime. - Validate offset/length in IndexInputSlicer.OpenSlice. Reject negative offset, negative length, and ranges that exceed the file. Previously a bad slice with offset+length > mapping.Length would read trailing zero bytes from the page-rounded mapping rather than failing — Java's MMapDirectory validates here too. - MMapIndexInput.Clone() now checks instanceClosed up front and throws AlreadyClosedException, rather than deferring the failure to the first read on the clone. Matches upstream Java's fail-fast contract. Tests: adds TestOpenSlice_OutOfBounds_Throws covering negative offsets/lengths, ranges past EOF, and the legitimate edge cases (empty slice at start, empty slice at file end, full file); TestCloneAfterRootDispose_ThrowsAlreadyClosed locking in the new Clone fail-fast contract; TestSliceNonZeroOffset_SeekToZero_ReadsSliceStart exercising slice-relative Seek(0) from a slice that begins mid-chunk. Updates TestCloneAfterDispose_ReadsThrowAlreadyClosed (the post- dispose half) to expect Clone() itself to throw. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

…1090 retry loop MemoryMappedFile.CreateFromFile accepts capacity: 0 to mean "size the mapping from the file's current length on disk." The framework does its own stat as part of the mapping creation, so there is no caller-side capacity for the file size to disagree with — the race window that apache#1090 was about is closed at the API boundary. This also lets us drop the FileStream we were holding alongside SharedMapping. The only thing it was being used for was capturing fc.Length to feed into our retry loop, plus being kept alive so the mapping had a handle. The path-based CreateFromFile overload opens its own handle and disposes it with the MemoryMappedFile, so we no longer need our own. Removes the retry loop in CreateMemoryMappedFile, the s_capacityRetryCount and s_maxCapacityAttemptsObserved test-observability counters, and the fileStream field on SharedMapping. Rewrites TestOpenInputConcurrentFileExtension_Issue1090 from a "race fired and was retried" assertion into a "OpenInput succeeds under concurrent file extension" smoke test. With capacity: 0 the original race no longer reaches the framework, so 8700 OpenInput iterations over 15s observed zero retries before the change. The test now shortens to a 5s window and simply asserts that every OpenInput completes cleanly while another thread extends/truncates the file.

…-while-mapped The path-based MemoryMappedFile.CreateFromFile overload internally opens the file with FileShare.Read. On Windows that blocks any subsequent open-for-write or open-for-delete on the same file while we hold the mapping. Callers like FreeTextSuggester build a temp index, dispose the directory, and then recursively delete the directory; on Windows that recursive delete fails with "The process cannot access the file ... because it is being used by another process" because Windows requires FILE_SHARE_DELETE on the existing handle for a delete to proceed against an open file. Switch back to opening our own FileStream so we control the share flags. We use FileShare.ReadWrite | FileShare.Delete to match the prior behavior (other writers/deleters can proceed; Windows will defer the actual unlink until our last close, which is the standard Unix-like semantic the rest of the framework expects). We still pass capacity: 0 to CreateFromFile so the framework does its own size stat — the apache#1090 race window stays closed. leaveOpen: false hands the FileStream's lifetime to the MMF, so we don't have to track it as a SharedMapping field. Zero-length files are handled up front rather than letting CreateViewAccessor reject the empty view: we dispose the FileStream eagerly and return an empty SharedMapping. Caught by Windows CI: TestFreeTextSuggester.TestBasic and siblings failed with InvalidOperationException("failed to remove ...") wrapped around IOException("write.lock ... being used by another process") on net8.0 / net472 / net48 Windows runners. Linux passed because Linux's "delete while open" semantics don't depend on the open handle's share mode. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

The slow path of ReadInt16/32/64 routed through base.ReadIntXX, which called back into our ReadByte 2-8 times via virtual dispatch. Replace with stackalloc + ReadBytes + BinaryPrimitives.ReadXxxBigEndian so the JIT can devirtualize the inner reads. ReadBytes(byte[]) and ReadBytes(Span<byte>) now share a private ReadBytesCore(ref byte, int) that takes a raw ref to skip the per-call Span ctor and per-iteration Slice/GetReference. Adds a small-copy switch (1/2/4/8) so the int slow paths avoid CopyBlockUnaligned entry overhead. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

Chunk's basePtr/length fields are internal-readonly and used outside the type, so they were renamed to PascalCase per review. The API scan flags any non-public field that doesn't match camelCase; add an exception regex for these two as suggested in the review.

…ing cleanup SharedMapping now owns and deterministically disposes the backing FileStream (leaveOpen: true) instead of relying on the finalizer; the MemoryMappedFile only borrows the handle and never disposes the stream object. Adds internal test seams (MMapIndexInput.Mapping, SharedMapping.IsFileStreamDisposed) and tests asserting the stream is disposed on input/slicer dispose. Fixes the two DisposeWhileHandlingException misuses (CreateAttempt and MapChunks): dispose via the swallowing overload then rethrow with a bare throw, so the original stack trace is preserved and there is no double-throw. Removes the dead catch/dispose guards in OpenInput and CreateSlicer (the constructors only set fields and cannot throw there) and documents the mapping-ownership and slice-lifetime contracts. Corrects the test comment that implied AlreadyClosedException is a distinct type from ObjectDisposedException. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

Wraps a real MMapDirectory in MockDirectoryWrapper and exercises the root input, slicer, and slice disposal paths. On dispose the wrapper throws "cannot close: there are still open files" if any directly-opened input/slicer/slice was not disposed, so this gates the MMap-specific disposal paths end to end (TestRandomChunkSizes already covers the OpenInput-via-IndexWriter path). Documents that clones are not tracked by upstream MockDirectoryWrapper and that this gate is at the IndexInput level, distinct from the FileStream-disposal seam test.

…ache#1013) Fixes a permanent leak of a MemoryMappedViewAccessor (and its mapped address space) when an MMapIndexInput is disposed on a different thread than the one holding its cached chunk rent, e.g. IndexInputSlicer.Dispose tearing down slices that other threads are still reading (the apache#1013 scenario). NightOwl888 reproduced this on PR apache#1267 as a non-zero undisposed-accessor openCount after a postings-format test run. Root cause: the cross-thread Dispose path correctly skips releasing the reader's rent (releasing it there could unmap the view under a live read, an AVE). But if that reader then stops reading without disposing on its own thread, the rent is never released, so the chunk's inFlight count stays >= 1, Chunk.ReleaseNative never runs, Chunk.accessor is never nulled and stays reachable via SharedMapping.Chunks[], so the accessor is never finalized and the view is never unmapped, for the process lifetime. Fix: on the cross-thread Dispose path, hand the stranded rent off to a finalizable StrandedRentReleaser whose finalizer calls Chunk.Release() exactly once. The releaser is a separate object (not a finalizer on MMapIndexInput, which the base IndexInput.Dispose() would un-arm via its unconditional GC.SuppressFinalize) referenced from the input, so its finalizer runs only once the input is unreachable, at which point no thread can be mid-read through it, making the Release (and any resulting unmap) AVE-safe. The same-thread Dispose path is unchanged and stays allocation- and finalizer-free; the hot read path is untouched. ReleaseCurrentChunk and HandOffStrandedRent both swap currentChunk via Interlocked.Exchange so a rent is released at most once. Adds TestStrandedChunkRentReclaimedByFinalizer (a TDD regression test that fails without the handoff and passes with it) plus two internal test-only Chunk seams (IsNativeReleased, IsNativeReleasedOrZeroRent). Verified against the nightly cross-thread/slicer stress tests (no AVE). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

…integration) Rebasing onto master pulled in apache#1357 (path validation for FSDirectory), which added EnsureCanRead(name) to MMapDirectory.OpenInput. On master, CreateSlicer delegated to OpenInput, so it was covered transitively. The PR's redesigned CreateSlicer builds its own SharedMapping and no longer routes through OpenInput, so it would have silently dropped that validation. Call EnsureCanRead(name) directly in CreateSlicer to preserve apache#1357's behavior. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

Replace the hand-rolled per-chunk "rent" state machine (packed state/CLOSED_BIT/RENT_INC, TryAcquire/Release/Close/ReleaseNative CAS loops) with the BCL's own SafeMemoryMappedViewHandle refcount: a per-chunk-crossing AcquirePointer/ReleasePointer is the drain barrier, and accessor.Dispose() defers the actual unmap until all references drain and fails a later crossing fast (ObjectDisposedException -> AlreadyClosedException). This is the .NET-native equivalent of the custom rent, correct by construction, and apache#1151-safe because the reference is taken once per chunk crossing, not per read (a per-read refcount touch is the ~218x concurrency cliff apache#1151 is about). The cross-thread Dispose deferral is still required: a disposer must not release a read reference the acquiring reader may be mid-dereference of, or Chunk.Close could unmap the view under it (AVE). A same-thread Dispose releases directly; a cross-thread Dispose hands the reference to a finalizable StrandedReadRefReleaser that releases it once the input is unreachable. This is proven necessary by TestConcurrentSliceReadVsSlicerDispose, which AVEs without it. Tests: replace the finalizer-reclamation test with deterministic cross-thread-dispose and clone-dispose leak tests that assert chunk views and the backing FileStream are released synchronously (no GC.Collect/WaitForPendingFinalizers). The clone-dispose test closes the gap NightOwl888 hit (apache#1267): MockDirectoryWrapper's open-files gate does not track clones, so a clone leaking its view on its own Dispose would not fail that gate but would keep the file mapped (blocking overwrite/ delete on Windows). All 4 nightly concurrent race tests pass. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

Pull the Lucene.NET-specific raw-pointer chunked read engine out of MMapDirectory.MMapIndexInput into a reusable base class. Upstream Java keeps this logic in ByteBufferIndexInput (a real Store class), but ours is a .NET-specific invention with no Java counterpart, so it lives under Support/ per convention (and gets no compatibility-level header). The base owns the cursor, the fast read paths (ReadByte/ReadInt*/ ReadBytes), the chunk-crossing logic, and the concurrency/teardown coordination (per-crossing read reference, cross-thread strand deferral, StrandedReadRefReleaser). A subclass supplies only the chunk source via four members: ChunkCount, TryAcquireChunk(int, out byte*), ReleaseChunk(int), ChunkLength(int). The engine keys the cached chunk by int index and never sees the underlying MemoryMappedViewAccessor. MMapIndexInput becomes a thin subclass that wires those four to a SharedMapping's Chunks plus Clone/DisposeChunkSource. MMapDirectory.cs drops from ~1330 to ~760 lines; behavior is unchanged and all existing TestMultiMMap tests (incl. the 4 nightly concurrent race tests) pass. The extraction's payoff is testability: a managed-byte[]-backed UnsafeChunkIndexInput subclass can unit-test the engine logic without real mmap - no host-crashing AVEs, and the cross-thread strand path can be forced deterministically with a barrier. TestUnsafeChunkIndexInput adds such a fixture covering read correctness across chunk boundaries, fail-fast (read after close -> AlreadyClosed), reference lifecycle, and the forced cross-thread strand (a reader parked inside TryAcquireChunk while another thread disposes the clone; asserts the engine defers rather than releasing the reader's reference). The GC/finalizer reclamation tail is left to the deterministic real-mmap tests, as it is inherently timing-dependent. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

…ently (apache#1013) Pins the invariant that a same-thread Dispose of the owning MMapIndexInput is not the Java unmap-hack. The owning thread reads and disposes the master same-thread while N other threads read clones sharing the master's mapping. Disposing the owner closes the shared chunks (requesting unmap), but the SafeHandle refcount defers the actual unmap until every reader's outstanding AcquirePointer reference drains, so sibling readers never dereference a freed view. The owner releases only its own reference; sibling readers see valid bytes or AlreadyClosed, never an AVE. Ran 16,690 interleaved iterations in 15s on net10.0 with no AVE/NRE/IOException.

…e#1151) Wire the MMapDirectory read engine to an IMMapReclaimer that defers each mapping's unmap until in-flight readers drain, replacing the cross-thread StrandedReadRefReleaser finalizer with a hazard-pointer-style handshake. - HazardMMapReclaimer: each reader owns a private depth slot; Enter announces a dereference and Exit drains it. Close publishes a closed flag and scans the slots, deferring the unmap until all readers drain (no AVE). Asymmetric fencing keeps the hot path fence-free where Interlocked.MemoryBarrierProcessWide is available (net core), falling back to a symmetric per-read barrier on net462/netstandard2.0. - Chunk caches its base pointer once at map time; the per-chunk-crossing AcquirePointer (the apache#1151 contention) is gone. Release performs the unmap. - UnsafeChunkIndexInput brackets each dereference with Enter/Exit; each clone re-registers for its own slot (ResetClonedCursor) so root and clones never share a depth counter. - Tests: rewrite the engine tests to the new model; add a PausingReclaimer that parks a reader inside the bracket to prove Close defers the unmap until drain. All engine + nightly real-mmap race tests pass (no AVE). Benchmark vs the finalizer: the asymmetric fence preserves the apache#1151 concurrency win (x8 ~4900 MiB/s, ~6x SimpleFS) but is still ~2.4x slower single-threaded; further hot-path optimization to follow.

…e reads Close the single-thread and concurrency gaps vs the finalizer baseline while keeping the lock-free, finalizer-free design. - Drop the IMMapReclaimer interface (HazardMMapReclaimer is the only impl); the read engine holds the concrete reclaimer + Slot, so Enter/Exit devirtualize and inline. - Asymmetric fencing: the hot path takes no StoreLoad barrier; Close issues a process-wide barrier (Interlocked.MemoryBarrierProcessWide, gated on the new FEATURE_MEMORYBARRIER_PROCESSWIDE) so every reader's announce is visible to the scan. net462/netstandard2.0 fall back to a symmetric per-read barrier. - The hot read paths call EnterCore/Exit directly instead of using/try-finally: the bracketed body is a raw Unsafe load that can only AVE (uncatchable) and never throws a managed exception, so the finally never runs. Removing the try region restores JIT enregistration and nearly halves SeqReadByte. Add a ReadScope ref struct for the using-friendly form (not on the hot path). - Tighten scopes to wrap only the dereference; tests use a slot OnEnterForTest hook instead of a reclaimer decorator. Benchmark (net10.0 Release, 64 MiB, 16 cores) vs the finalizer: SeqReadByte 1.71 vs 1.22 ns/byte (1.4x, and faster than SimpleFS 1.69) Concurrent x8 ~4900 vs 6293 MiB/s (78%, still ~4.6x SimpleFS) The apache#1151 concurrency win is preserved.

Slot.Exit decremented Depth with a plain store on the fast path. The protected pointer load in the caller and the Depth-- have no data dependency, so on a weakly-ordered CPU (ARM64) the decrement could become globally visible before the load retires - letting Close's scan observe Depth==0 and unmap the page while the load is still outstanding (AccessViolationException). The asymmetric process-wide barrier in Close only orders the Enter/announce side; the Exit/retire side needs a release store so the load completes first. Use Volatile.Write for the decrement on all target frameworks (the net462/netstandard2.0 fallback already did this; the fast path had dropped it). Latent on x64 (TSO does not reorder loads after stores), reachable on ARM64. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

- Rename HazardMMapReclaimer -> DrainReclaimer: the type is not MMap-specific (Register/Enter/Exit/Close over any shared resource). It's a per-user drain barrier, hazard-pointer-inspired but using a re-entrancy counter rather than tagging a pointer, so the name reflects what it does. Generalize the class doc. - Use the ReadScope/using form on the bulk ReadBytesCore copy (amortized over a whole chunk, so the try-finally is negligible - confirmed 0.063 ns/byte), which also gives ReadScope/Enter() a real use instead of leaving them dead. - Fix accessor leak: the Chunk ctor now does a fallible AcquirePointer, so wrap its construction to dispose the in-flight accessor if it throws (it isn't in result[] yet, so DisposeChunks would miss it). - Refresh stale doc-comments that still described the old per-chunk-crossing read reference / SafeHandle-refcount drain model (the comment at the chunk- creation site actively contradicted the new cached-pointer code).

Unit tests for the lock-free DrainReclaimer primitive, independent of MMapDirectory: registration returns distinct slots, Enter/Exit balances and is re-entrant, the ReadScope using form ends the bracket, Enter after Close (and on a slot registered after Close) throws AlreadyClosed without leaving depth elevated, Close cleans up immediately when idle, defers while a user is inside the bracket (via the OnEnterForTest seam) then runs on drain, runs the cleanup exactly once with many users racing, and a nightly concurrent stress test asserting the cleanup never runs while a user is inside the bracket (the use-after-free analog) across 2000 iterations.

Add #nullable enable to match the adjacent Support/ files and annotate the two null-bearing fields (_unmap, OnEnterForTest).

Add two MMapDirectory tests for the determinism guarantee against real mapped memory, using only the existing zero-cost SetOnEnterForTest seam (a null-check already on the hot path - no new production overhead): - TestCloseWhileCloneReadingDefersUnmapThenReleasesOnDrain: the owner is disposed WHILE a clone is parked mid-read; the chunks must stay mapped (deferred), then unmap the instant that last reader drains - with no GC/finalizer step. This is the close-while-reading ordering the existing tests didn't cover. - TestLastSliceFinishedThenSlicerDisposeUnmapsDeterministically: a slice reads to completion (drained), then the slicer is disposed -> every chunk and the FileStream are unmapped synchronously. Also sweep the MMap tests + comments inherited from the mmap-redesign branch that described the old per-chunk-crossing read-reference / SafeHandle-refcount drain / "shared View" / TryEnterRead / "chunk rent" model, which no longer exists on this branch, and rephrase them for the DrainReclaimer design. Comment-only; behavior and assertions unchanged. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

Instead of deferring the cleanup to whichever reader drains last, Close now spin-waits (SpinWait, which escalates to yielding) until every in-flight user has drained, then runs the cleanup inline. So SharedMapping.Dispose is now synchronous: when it returns, the views are unmapped and the FileStream is closed - matching the Lucene 10.x shared-Arena close model (which likewise spins the closing thread). This is deadlock-free under the one-input-per-thread contract: a bracket is never held across calls (each read closes its own Enter/Exit before returning), so the thread calling Close can never itself hold a bracket open. The wait only ever blocks on other threads' short, bounded reads. Simplifies the primitive: Exit is now a plain release-store decrement (no reclaim trigger), and the _unmap field, _reclaimed once-guard, and the 100ms spin bound are gone. Read hot path is unchanged (AdventureWorks apache#1151 MMap parallel ~0.66s, same as before; Exit is now cheaper). Updated the tests that asserted the deferred behavior to assert blocking + synchronous unmap. All engine + 4 nightly real-mmap race tests pass on arm64 (no AVE).

…imary Add the missing [LuceneNetSpecific] attribute to TestSharedMappingLifecycle (it tests the LUCENENET-specific SharedMapping/single-MemoryMappedFile-per-file refactor and has no upstream Java counterpart; the other untagged tests in this file are genuine 4.8.1 Java ports and correctly stay untagged). Also rename the "master" IndexInput local/prose to "primary" in the three tests added in this PR (TestConcurrentCloneReadVsDispose_Issue1013, TestSameThreadOwnerDisposeWhileSiblingClonesRead_NoAVE, TestConcurrentCloneVsDispose_RaceScenario) for culturally-aware terminology, and refresh two stale comments that said the reclaimer "defers" the unmap (it now blocks until drained). The Java-ported TestCloneSafety keeps its original wording. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

…dNames These PascalCase internal fields can't satisfy the camelCase/ALL_CAPS private- field rule: Depth is accessed via ref (Volatile.Read/Write(ref slot.Depth)), so it must stay a field, and OnEnterForTest is the test seam. Add both to the exception regex, matching the existing precedent for MMapDirectory+Chunk. BasePtr/Length (same situation: ref-accessed field-like members of a nested helper class).

…ture flag Delete ConcurrentDictionaryExtensions (TryRemove(KeyValuePair)) - it was added during early MMap PR feedback for a ConcurrentDictionary-based mapping registry that was replaced by SharedMapping/DrainReclaimer, and now has zero usages. Also drop its companion gate FEATURE_CONCURRENTDICTIONARY_TRYREMOVE_KEYVALUEPAIR (new in this PR, used nowhere else). Rename FEATURE_MEMORYBARRIER_PROCESSWIDE -> FEATURE_INTERLOCKED_MEMORYBARRIERPROCESSWIDE to match the FEATURE_<TYPE>_<MEMBER> convention (the API is Interlocked.MemoryBarrierProcessWide), like FEATURE_CONDITIONALWEAKTABLE_ENUMERATOR / FEATURE_STREAM_READEXACTLY.

This is now ready for review. All tests pass here on GitHub and ~~on Azure DevOps~~.

I simplified the cleanup logic so that it no longer tries to clean up on Exit, but instead spin-waits (like Lucene 10.x) at the close caller until all critical regions have exited. This means that the cleanup is back to being truly deterministic (although, like in Lucene 10.x, subsequent readers that try to enter a critical region after close has been requested will get an AlreadyClosedException).

I feel good enough about this that I'm going to mark #1361 as draft just for reference.

Edit: I had my build runs mixed up on ADO. There is one failure I'll investigate on net48:

The active test run was aborted. Reason: Test host process crashed : Unhandled Exception: System.NullReferenceException: Object reference not set to an instance of an object.
   at Lucene.Net.Store.UnsafeChunkIndexInput.ReadByte() in /_/src/Lucene.Net/Support/UnsafeChunkIndexInput.cs:line 221
   at Lucene.Net.Store.TestMultiMMap.<>c__DisplayClass53_0.<TestCrossThreadCloneDisposeWhileReading>b__0() in /_/src/Lucene.Net.Tests/Store/TestMultiMMap.cs:line 2231

   at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state)
   at System.Threading.ThreadHelper.ThreadStart()

TestCrossThreadCloneDisposeWhileReading crashed the test host on net48 x64 with a NullReferenceException in ReadByte at *(readBase + pos): a clone being read on thread A was disposed on thread B, and Dispose called ReleaseCurrentChunk(), nulling readBase while thread A sat between its `pos < currentEnd` check and its dereference. Dispose now only zeroes currentEnd (the fail-fast gate) and no longer nulls readBase. There is no native reference tied to the cursor (the DrainReclaimer owns reclamation, and keeps the view mapped until the owning root closes), so a stale readBase is harmless: the in-flight read completes against the still-mapped view, and the zeroed currentEnd makes every subsequent read drop to the slow path and throw AlreadyClosed. readBase is now only ever nulled by the reading thread itself (Seek / EnsureCurrentChunk / clone setup), never cross-thread, so the race is structurally eliminated. The fields are GC'd with the instance. Latent on net10 (timing-lucky in CI); manifested as a host crash on net48 x64. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

Okay, I haven't reviewed the code yet, but I checked the behavior. I did a complete test run in Release mode locally and here is the test log:

{
    "assert": "true",
    "tests": {
        "awaitsfix": "false",
        "verbose": "false"
    }
}

I saw this happen at least twice, so I suspect there may be an issue with that test rather than this PR.

I haven't reviewed the code yet, though. I just wanted to see whether this fixes the issues in #1361, and it does.

Although, see #1400. This branch wasn't rebased against the latest master branch and initially I saw many CheckIndex failures. That gave me pause on this because I thought there was something seriously wrong. But, it turns out that #1360 hasn't yet been included here, so those errors were only caused because the Debug.Assert() statements were invalid and I was running in Debug mode.

Note that with awaitsFix: "true", the JRE crash test also holds open files. But #1292 isn't included here, which is supposed to fix that. I didn't attempt a rebase to work out whether that fix still holds with this directory implementation.
