wired through BlobEnvironment, Environment, VSCEnvironment, DfsServer, and FilesystemHandler. - Replace non-atomic copy+delete rename with persistence-level renameBlob() and renameBlobsByPrefix() on both LokiJS and SQL stores, keeping directory renames atomic and avoiding unnecessary extent copies. - Extract and forward If-Match, If-None-Match, If-Modified-Since, and If-Unmodified-Since conditional headers on DFS getProperties, read, and delete operations via ModifiedAccessConditions. - Expose full blob lease lifecycle (acquire, release, renew, break, change) on the DFS endpoint by detecting x-ms-lease-action and delegating to the existing IBlobMetadataStore lease infrastructure. - Add DFS-specific error helpers for conditional and lease failures. - Extend dfsProxy.test.ts with tests for conditional headers, all lease operations, and atomic directory rename with children verification.

From 956c39cc3823667fe154478ad1cb835bdc3708c3 Mon Sep 17 00:00:00 2001 From: Jasmin Savard Date: Wed, 18 Mar 2026 03:04:13 -0400 Subject: [PATCH 04/34] Add HNS parent-child hierarchy table for directory relationship tracking Implement the dedicated hierarchy table required by the Azurite ADLS Gen2 Implementation Guidance wiki ("Add table matching each item with parent"). - IBlobMetadataStore: Add registerHnsPath, unregisterHnsPath, unregisterHnsPathsByPrefix, renameHnsPaths, isHnsDirectoryEmpty, and hnsPathExists methods for managing parent-child relationships. - LokiBlobMetadataStore: New $HNS_HIERARCHY$ collection indexed on (accountName, containerName, path) and (parentPath) for fast lookups. - SqlBlobMetadataStore: New HnsHierarchy table with unique path index and parentPath index; rename operations use transactions. - PathHandler: create() registers paths in hierarchy; delete() uses isHnsDirectoryEmpty() for non-recursive guard and cleans up hierarchy records; renamePath() updates hierarchy atomically; ensureIntermediateDirectories() registers intermediate dirs. - Tests: non-empty directory delete returns 409; recursive delete succeeds; auto-created intermediate directories are visible via HEAD.

add identity field to IDfsContext. - DfsAuthenticationMiddleware: Extract identity claims (oid, upn, tid, appid) from Bearer JWT tokens when ACL mode is active; store in DFS context for downstream enforcement. - DfsAclEnforcer: New module implementing POSIX ACL evaluation: - Parses ACL strings ("user::rwx,user:oid:r-x,group::r-x,other::---") - Evaluates in POSIX order: owner -> named user -> group -> other - Applies mask entries to limit named user/group permissions - $superuser and unauthenticated requests bypass checks - Maps operations to required permissions (r/w/x) - PathHandler: Add enforceAcl() helper; check ACL before getProperties, read, delete, and update operations; accept OAuthLevel from factory. - DfsRequestListenerFactory: Pass OAuth level to PathHandler. - Tests: 19 unit tests for ACL enforcer covering parsing, bypass scenarios, owner/named-user/group/other permissions, mask application, and UPN matching. All passing.

Now always uses listBlobs prefix scan (no delimiter) to find ALL descendant blobs regardless of how they were created, then deletes them all before removing the directory marker itself. Fixes: DeleteDirectory_WithContents_DeletesAll test failure where directoryClient.DeleteAsync(recursive: true) deleted the directory marker but left child blobs intact.

Introduces renamePathAtomic on IBlobMetadataStore that collapses all three mutations into a single call: - LokiJS: all operations are synchronous LokiJS calls with no intermediate awaits, so the event loop never yields during the rename. - SQL: all operations run inside a single Sequelize transaction, giving database-level atomicity and rollback on failure. PathHandler.renamePath is updated to call renamePathAtomic instead of the three individual methods.

DFS tests pass true explicitly - DFS routing: add x-ms-lease-action and ?recursive signals so lease/delete ops reach DFS handler - DfsRequestListenerFactory: when enableHierarchicalNamespace=true at server level, all containers are treated as HNS-enabled (skip per-container metadata check, matching Azure account-wide HNS) - DfsContext URL parsing: detect DataLake SDK move() bug where destination URL omits account name on IP-based emulator URLs; fall back to EMULATOR_ACCOUNT_NAME when first path segment is not a known account - PathHandler.getProperties: forward 412 ConditionNotMet instead of 500 - dfsProxy tests: use dfsAxios instance with DataLake user-agent for HEAD/DELETE calls so they reach the DFS router; enable skipApiVersionCheck for SDK version compatibility All 36 DFS @loki tests pass.

Subsequent `getProperties` falls back to the server-wide flag. +**Fix:** Read existing metadata with `getContainerProperties`, preserve `azurite_hns_enabled`, then overlay client-supplied properties before calling `setContainerMetadata`. + +#### [P2-C-2] `ContainerHandler.setMetadata` (Blob API) also wipes `azurite_hns_enabled` 🔲 +**File:** `src/blob/handlers/ContainerHandler.ts` lines 202–230 +**Problem:** `PUT ?comp=metadata` replaces the entire metadata map; `azurite_hns_enabled` is not preserved.

SDK clients receive `x-ms-meta-azurite_hns_enabled` as a user metadata header, polluting the metadata map and enabling round-trip corruption. +**Fix:** Filter `azurite_hns_enabled` from metadata in `getContainerProperties` response, mirroring `FilesystemHandler.getProperties`. + +#### [P2-C-4] `x-ms-meta-azurite_hns_enabled` header lets clients forge the HNS flag 🔲 +**File:** `src/blob/dfs/handlers/FilesystemHandler.ts` `extractMetadata` ~line 224 +**Problem:** `extractMetadata` reads all `x-ms-meta-*` headers verbatim, including `x-ms-meta-azurite_hns_enabled`. A client can send this header to disable HNS on any writable container. The `x-ms-properties` path already filters this key; the `x-ms-meta-*` path does not. +**Fix:** In `extractMetadata`, skip the `azurite_hns_enabled` key. + +--- + +### Major + +#### [P2-M-1] `listPaths` returns `200 {paths:[]}` instead of `404` for non-existent directory 🔲 +**File:** `src/blob/dfs/handlers/PathHandler.ts` lines 361–430 +**Problem:** When `?directory=nonexistent` is set and no blobs match, the response is `200 { paths: [] }`. Azure returns `404 PathNotFound`. DataLake SDK `listPaths` relies on 404 to detect missing directories. +**Fix:** After `listBlobs`, if results are empty and `directory` was specified, check if the directory blob exists; if not, return `sendDfsError(res, pathNotFound(directory))`. + +#### [P2-M-2] `PathHandler.delete` does not handle 412 conditional header mismatch 🔲 +**File:** `src/blob/dfs/handlers/PathHandler.ts` lines 204–211 +**Problem:** The `catch` block only handles 404.

Two concurrent appends at `position=0` both pass the check, generate the same block ID, and the second overwrites the first.

Coerce metadata values through String() before base64-encoding to avoid Buffer type errors. Replace the fragile body extraction in appendData with an explicit Buffer/string/array/object branch so plain-object bodies (e.g. {}) are treated as empty rather than causing a crash. Adds a regression test for both cases.
