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 d1f9f18de1a7a4b5a11da66bdc92017a3edb0672 Mon Sep 17 00:00:00 2001 From: Jasmin Savard Date: Wed, 18 Mar 2026 03:04:13 -0400 Subject: [PATCH 04/50] 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.

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.

validate position against actual implied length and return InvalidFlushPosition if mismatched - SqlBlobConfiguration/SqlBlobServer: thread enableHierarchicalNamespace so SQL mode enables DFS routing consistently with Loki mode - DfsRequestListenerFactory: thread skipApiVersionCheck and disableProductStyleUrl into createDfsContextMiddleware so DFS context parsing honours the same server config as Blob - DfsAuthenticationMiddleware: gate unauthenticated passthrough on oauth === undefined so requests are rejected when OAuth is explicitly configured - PathHandler helpers: pass ctx.requestId to all createStorageContext() calls for consistent request correlation across metadata store operations Co-Authored-By: Claude Sonnet 4.6 --- Dockerfile | 4 +- Dockerfile.Windows | 4 +- README.md | 17 ++-- docs/designs/ADLS-gen2-parity.md | 27 ++++--- package.json | 10 --- src/azurite.ts | 6 -- src/blob/BlobEnvironment.ts | 20 ----- src/blob/BlobRequestListenerFactory.ts | 4 +- src/blob/BlobServerFactory.ts | 3 +- src/blob/DfsConfiguration.ts | 34 -------- src/blob/DfsRequestListenerFactory.ts | 6 +- src/blob/DfsServer.ts | 49 ----------- src/blob/IBlobEnvironment.ts | 2 - src/blob/SqlBlobConfiguration.ts | 3 +- src/blob/SqlBlobServer.ts | 3 +- src/blob/dfs/DfsAuthenticationMiddleware.ts | 5 +- src/blob/dfs/handlers/FilesystemHandler.ts | 7 +- src/blob/dfs/handlers/PathHandler.ts | 90 +++++++++++++++------ src/blob/main.ts | 6 -- src/blob/utils/constants.ts | 2 - src/common/Environment.ts | 22 +---- src/common/Telemetry.ts | 6 +- src/common/VSCEnvironment.ts | 8 -- tests/blob/dfsProxy.test.ts | 18 +---- tests/blob/dfsSDKIntegration.test.ts | 16 +--- 25 files changed, 113 insertions(+), 259 deletions(-) delete mode 100644 src/blob/DfsConfiguration.ts delete mode 100644 src/blob/DfsServer.ts diff --git a/Dockerfile b/Dockerfile index 4406ece8c..566b9de7b 100644 --- a/Dockerfile +++ b/Dockerfile @@ -42,7 +42,5 @@ EXPOSE 10000 EXPOSE 10001 # Table Storage Port EXPOSE 10002 -# DFS (ADLS Gen2) Port -EXPOSE 10004 -CMD ["azurite", "-l", "/data", "--blobHost", "0.0.0.0", "--dfsHost", "0.0.0.0", "--queueHost", "0.0.0.0", "--tableHost", "0.0.0.0"] +CMD ["azurite", "-l", "/data", "--blobHost", "0.0.0.0", "--queueHost", "0.0.0.0", "--tableHost", "0.0.0.0"] diff --git a/Dockerfile.Windows b/Dockerfile.Windows index 1ffa6a720..c43b9cf34 100644 --- a/Dockerfile.Windows +++ b/Dockerfile.Windows @@ -67,11 +67,9 @@ EXPOSE 10000 EXPOSE 10001 # Table Storage Port EXPOSE 10002 -# DFS (ADLS Gen2) Port -EXPOSE 10004 ENTRYPOINT "cmd.exe /S /C" WORKDIR C:\\Node\\node-v22.12.0-win-x64\\ -CMD azurite -l c:/data --blobHost 0.0.0.0 --dfsHost 0.0.0.0 --queueHost 0.0.0.0 --tableHost 0.0.0.0 \ No newline at end of file +CMD azurite -l c:/data --blobHost 0.0.0.0 --queueHost 0.0.0.0 --tableHost 0.0.0.0 \ No newline at end of file diff --git a/README.md b/README.md index f8addbcd1..762f0dee0 100644 --- a/README.md +++ b/README.md @@ -189,8 +189,6 @@ Following extension configurations are supported: - `azurite.blobHost` Blob service listening endpoint, by default 127.0.0.1 - `azurite.blobPort` Blob service listening port, by default 10000 -- `azurite.dfsHost` DFS service listening endpoint, by default 127.0.0.1 -- `azurite.dfsPort` DFS service listening port, by default 10004 - `azurite.blobKeepAliveTimeout` Blob service keep alive timeout in seconds, by default 5 - `azurite.queueHost` Queue service listening endpoint, by default 127.0.0.1 - `azurite.queuePort` Queue service listening port, by default 10001 @@ -228,18 +226,17 @@ To view Azurite logs in Visual Studio Code: > Note.

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. A Blob SDK `SetContainerMetadata` call after creating an HNS container silently disables HNS. +**Fix:** Same as P2-C-1 — read existing metadata and preserve the reserved key. + +#### [P2-C-3] `azurite_hns_enabled` leaks as user-visible metadata via Blob API 🔲 +**File:** `src/blob/handlers/ContainerHandler.ts` `getContainerProperties` ~line 133 +**Problem:** `GetContainerProperties` returns metadata unfiltered. 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. A `deleteBlob` 412 (e.g., `If-Match` header mismatch) is logged and returned as 500 `InternalError`. `getProperties` handles 412 correctly. +**Fix:** Add a 412 handler in the catch block, same pattern as `getProperties`. + +#### [P2-M-3] `DfsContext` 400 response missing `x-ms-error-code` header 🔲 +**File:** `src/blob/dfs/DfsContext.ts` lines 101–104 +**Problem:** Missing account name sends `res.status(400).json(...)` directly, bypassing `sendDfsError`. Azure SDKs require the `x-ms-error-code` header for structured error parsing. +**Fix:** Replace with `sendDfsError(res, { statusCode: 400, code: "InvalidQueryParameterValue", message: "Account name is required." }); return;` + +#### [P2-M-4] Multi-block read stream not destroyed on error — resource leak 🔲 +**File:** `src/blob/dfs/handlers/PathHandler.ts` lines 319–329 +**Problem:** `stream.on("error", reject)` does not call `stream.destroy()`. The stream continues emitting after the Promise rejects, potentially writing to a closed response. +**Fix:** `stream.on("error", (err) => { stream.destroy(); reject(err); });` + +#### [P2-M-5] `x-ms-lease-break-period` NaN propagated to `breakBlobLease` 🔲 +**File:** `src/blob/dfs/handlers/PathHandler.ts` `breakLease` ~line 953 +**Problem:** `parseInt(header, 10)` returns `NaN` for non-numeric values and is passed directly to `breakBlobLease`, producing undefined behavior instead of `400 InvalidHeaderValue`. +**Fix:** Validate the parsed value; return 400 if NaN. + +#### [P2-M-6] Concurrent appends at same position cause silent data loss 🔲 +**File:** `src/blob/dfs/handlers/PathHandler.ts` lines 475–543 +**Problem:** Position check + `stageBlock` are not atomic. Two concurrent appends at `position=0` both pass the check, generate the same block ID, and the second overwrites the first. The first append's extent is leaked. +**Fix:** Document as known limitation, or make position check + block stage a single atomic metadata operation. + +#### [P2-M-7] `listPaths` returns hardcoded owner/group/permissions, ignoring stored ACL 🔲 +**File:** `src/blob/dfs/handlers/PathHandler.ts` lines 394–413 +**Problem:** Every entry in `listPaths` response has `owner: "$superuser"`, `group: "$superuser"`, `permissions: "rwxr-x---"` regardless of stored ACL. ACL-aware applications reading from `listPaths` always see wrong data. +**Fix:** Include `blob.metadata?.dfsAclOwner || "$superuser"` etc. per entry, or document as a known limitation. + +--- + +### Minor + +#### [P2-m-1] `dynamic require("crypto")` inside hot path 🔲 +**File:** `src/blob/dfs/handlers/PathHandler.ts` `appendData` ~line 499 +**Fix:** Move to top-level `import { createHash } from "crypto"`. + +#### [P2-m-2] `parentPath` variable shadowed inside `try` block 🔲 +**File:** `src/blob/dfs/handlers/PathHandler.ts` lines 52 and 104 +**Problem:** Outer `parentPath` (ACL check, empty-string for root) and inner `parentPath` (HNS registration, `null` for root) have the same name but different semantics. +**Fix:** Rename the inner variable to `hnsParentPath`. + +#### [P2-m-3] `FilesystemHandler.setProperties` does not preserve existing user metadata 🔲 +**File:** `src/blob/dfs/handlers/FilesystemHandler.ts` lines 182–207 +**Problem:** Beyond the HNS flag (P2-C-1), user metadata set via `x-ms-meta-*` on prior requests is also overwritten on every `PATCH ?resource=filesystem`. +**Fix:** Read existing metadata and merge, overwriting only the keys from `x-ms-properties`. + +#### [P2-m-4] Dispatch mis-routes `?resource=filesystem` + non-empty path 🔲 +**File:** `src/blob/DfsRequestListenerFactory.ts` lines 87–90 +**Problem:** When `resource=filesystem` AND `ctx.path` is set, any HTTP method is mapped to `Filesystem_ListPaths`. A `PUT` with both conditions would silently become a list operation. +**Fix:** Add a method check (`&& method === "GET"`) or return 400 for the combination. + +#### [P2-m-5] `ensureIntermediateDirectories` accepts a file as a path component 🔲 +**File:** `src/blob/dfs/handlers/PathHandler.ts` `ensureIntermediateDirectories` ~line 1128 +**Problem:** If `a/b` already exists as a file, the loop skips creating the directory entry and the create of `a/b/c` proceeds. Azure returns an error in this case. +**Fix:** After `safeGetBlobProperties`, check if the existing entry is actually a directory; if not, return an appropriate error. + +--- + +## Pass 2 — Test Gaps | # | Scenario | Related issue | |---|----------|---------------| -| 1 | Multi-cycle `append→flush→append→flush` on the same file | C-1 | -| 2 | Rename to an already-existing destination | M-1 | -| 3 | ETag format validation (`"0x..."` pattern) | M-8 | -| 4 | `setProperties` with reserved key names (`hdi_isfolder`, ACL keys) | M-2 | -| 5 | Container/filesystem delete cleans up HNS hierarchy rows | C-2 | -| 6 | ACL enforcement blocks `create` when caller lacks write on parent | C-5 | -| 7 | Non-numeric `?position=garbage` on append/flush | m-5 | -| 8 | Path names containing `%` or `_` in SQL rename/delete | M-7 | +| 1 | `setProperties` PATCH then verify `x-ms-namespace-enabled` still correct | P2-C-1 | +| 2 | Blob API `SetContainerMetadata` then verify DFS still works | P2-C-2 | +| 3 | `GetContainerProperties` via Blob API does not expose `azurite_hns_enabled` | P2-C-3 | +| 4 | `listPaths ?directory=nonexistent` returns 404 | P2-M-1 | +| 5 | `delete` with non-matching `If-Match` returns 412 | P2-M-2 | +| 6 | `listPaths` returns correct `owner`/`group`/`permissions` after `setAccessControl` | P2-M-7 | From 14b1f9a0c4a80a53ec80e3905d7665de048b16e6 Mon Sep 17 00:00:00 2001 From: Jasmin Savard Date: Fri, 1 May 2026 08:52:16 -0400 Subject: [PATCH 26/50] =?UTF-8?q?fix(dfs):=20address=20pass-2=20review=20?= =?UTF-8?q?=E2=80=94=20HNS=20metadata=20safety,=20listPaths,=20error=20han?= =?UTF-8?q?dling?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Criticals (azurite_hns_enabled integrity): - FilesystemHandler.setProperties: read existing metadata first, preserve HNS flag and existing user metadata before applying x-ms-properties overlay (P2-C-1, P2-m-3) - FilesystemHandler.extractMetadata: filter x-ms-meta-azurite_hns_enabled to block forgery (P2-C-4) - ContainerHandler.setMetadata: preserve azurite_hns_enabled from existing metadata when Blob API SetContainerMetadata replaces the metadata map (P2-C-2) - ContainerHandler.getContainerProperties: filter azurite_hns_enabled from user-visible metadata in Blob API response (P2-C-3) - FilesystemHandler: add newEtag() import; use it in setProperties Majors: - listPaths: return 404 when specified directory does not exist (P2-M-1) - listPaths: read stored dfsAclOwner/dfsAclGroup/dfsAclPermissions per entry instead of hardcoded $superuser defaults (P2-M-7) - PathHandler.delete: handle 412 ConditionNotMet from conditional-header mismatch (P2-M-2) - DfsContext: replace raw res.status(400).json() with sendDfsError so response includes x-ms-error-code header (P2-M-3) - Multi-block read: call stream.destroy() on error to prevent resource leak (P2-M-4) - breakLease: validate x-ms-lease-break-period for NaN; return 400 if invalid (P2-M-5) - appendData: document TOCTOU limitation for concurrent appends (P2-M-6) Minors: - PathHandler: replace dynamic require("crypto") with top-level import (P2-m-1) - PathHandler.create: rename inner parentPath to hnsParentPath to avoid shadowing (P2-m-2) - DfsRequestListenerFactory: restrict resource=filesystem + ctx.path dispatch to GET only (P2-m-4) - ensureIntermediateDirectories: throw 409 if a file occupies an intermediate path (P2-m-5) Tests (4 new in dfsProxy.test.ts): - HNS flag survives filesystem setProperties PATCH - listPaths returns 404 for non-existent directory - delete with non-matching If-Match returns 412 - listPaths returns stored ACL owner/group per path 55 DFS @loki tests passing.

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.

validate position as numeric - DfsContext.extractDfsPartsFromPath(): the IP/no-account-hostname fallback that reinterprets the first URL segment as a filesystem name (dropping in devstoreaccount1 as the account) previously applied to EVERY request on those hostnames, not just DataLake SDK rename destinations. This broke DFS URL parsing for legitimate non-emulator account names on IP-based endpoints (e.g. /myaccount/fs/path). Restricted the fallback to requests carrying the x-ms-rename-source header, matching its original intent (SDK move() destination URLs). - PathHandler.appendData / flushData: the query parameter was parsed with parseInt() but never validated, so a non-numeric value (e.g. position=garbage) silently became NaN and was compared against the expected offset, producing a 409 ConditionNotMet/InvalidFlushPosition with a misleading NaN-laden message. Real ADLS Gen2 returns 400 InvalidQueryParameterValue for a malformed position. Both handlers now validate position is a non-negative integer string up front and return 400 InvalidQueryParameterValue otherwise; updated the existing 'rejects non-numeric append position gracefully' test to assert the new 400/InvalidQueryParameterValue behavior instead of accepting 202/409.

All 6 issues below are classified Critical (auth bypass or write-path integrity). 1. Unauthenticated DFS access bypass (DfsAuthenticationMiddleware.ts): removed the blanket "no credentials + no --oauth => pass through" branch, which let ANY request through with zero credentials whenever the server wasn't started with --oauth. This was remotely triggerable against the Blob endpoint too, since BlobRequestListenerFactory routes any request whose User-Agent contains "datalake" (fully client-controlled) into the DFS pipeline. Added PublicAccessAuthenticator to the DFS authenticator chain (same as the Blob pipeline already has) so anonymous access is only ever granted via a real container public-access check, never a blanket pass-through. Documented that the UA-based routing heuristic must never be treated as an authorization signal, now that both pipelines independently enforce real auth. 2. lease() had zero ACL enforcement (PathHandler.ts): any authenticated caller in --oauth acl mode could acquire/break/steal a lease on any path regardless of ACL. Added enforceAcl(..., "w") at the top of lease() before dispatch to the sub-actions. 3. Append/flush bypassed lease enforcement entirely (PathHandler.ts): stageBlock() was called with leaseAccessConditions hardcoded to undefined, and commitBlockList() wasn't passed any conditions at all, so a client with no lease could append/flush data to a leased file. Now both extract and thread x-ms-lease-id through to the metadata store, which validates it via the same BlobWriteLeaseValidator/ BlobReadLeaseValidator used by the Blob pipeline. Also added 412 ConditionNotMet mapping to both handlers' catch blocks, and closed a gap where the "nothing to flush" fast path skipped the position check entirely (a flush(position=) on an unmodified file returned a false 200 instead of validating against the actual committed length). 4. Rename force-deleted the destination with zero lease/conditional-header checks (PathHandler.ts renamePath): the destination could be under an active lease and would still be silently overwritten. Now extracts x-ms-lease-id/If-Match/etc. for the destination and threads them into deleteBlob(); a leased destination without the correct lease id now returns 412 instead of being deleted. Also added x-ms-source-lease-id support: the source blob is now fetched via getBlobProperties() with lease conditions (instead of the ACL-only safeGetBlobProperties), so a leased source without the matching source-lease-id is rejected before any mutation happens. 5. create() ignored conditional headers entirely (PathHandler.ts): there was no If-None-Match/overwrite=false handling for files (only directories had an existence check), so Azurite always overwrote silently where real ADLS Gen2 returns 409 PathAlreadyExists. Now extracts modifiedAccessConditions/leaseAccessConditions and passes them into createBlob(), which already supported and validated them. 6. Rename didn't validate type compatibility (PathHandler.ts renamePath): a file could silently replace an empty directory, or a directory could replace a file, since only "non-empty directory" was rejected. Added an explicit isDir-vs-destIsDir check that returns 409 PathConflict before any destination deletion happens. Fixed 2 pre-existing tests (dfsReproduction.test.ts) that only passed because they relied on the removed anonymous-access bypass; switched them to use account SAS like every other DFS test file. Added 7 new regression tests across dfsProxy.test.ts and dfsAclIntegration.test.ts covering each of the 6 fixes above (lease-gated append/rename, rename type-mismatch in both directions, destination-lease-respecting rename, lease-gated ACL enforcement, and overwrite=false create semantics).

charset=UTF-8 Content-Transfer-Encoding: 8bit Continuing the independent Claude review of PR #2635. Fixes the following warnings (numbering matches the review summary posted earlier): 1. HNS default `false` in 4 handler constructors (ContainerHandler, ServiceHandler, BlobHandler, BlobBatchHandler) contradicted the server-wide default of `true` used everywhere else. Currently dead code in the shipped server paths (BlobServer/SqlBlobServer always pass the flag explicitly), but a landmine for any future/alternate construction path (tests, embedding) that forgets to thread it. All 4 now default to EMULATOR_ACCOUNT_ISHIERARCHICALNAMESPACEENABLED_DEFAULT. 2. ServiceHandler.listContainersSegment leaked the internal azurite_hns_enabled metadata key to clients with include=metadata, unlike GetContainerProperties and DFS getProperties which both filter it. Applied the same filter. 3. DfsContext's URL/path parsing (extractDfsPartsFromPath) could throw a raw URIError on a malformed percent-encoded segment, which Express's default error handler would turn into an HTML/plain response instead of the documented DFS JSON error contract. Wrapped in try/catch, returns 400 InvalidUri. 4. DfsAuthenticationMiddleware's unclassified-operation fallback mapped to a read op (Blob_GetProperties) for SAS permission checking — the least restrictive choice. Changed to the most restrictive (BlockBlob_Upload) so an as-yet-unclassified request is never under-enforced. 5. DfsRequestListenerFactory's terminal error handler flattened everything to a generic 500 and echoed error.message (possible internal detail leak) verbatim to the client. Now maps known body-parser error shapes (entity.too.large -> 413, entity.parse.failed -> 400) and returns a sanitized message for the true 500 fallback, logging the real error server-side instead. 6. DfsAclEnforcer silently fell through named-group ACL entries (no AAD membership resolution in the emulator) to "other" permissions with no signal to the operator. Added a one-time warn-level log per check when named-group entries are present but unevaluated. 8. setAccessControlRecursive only ACL-checked the root path (via update()'s top-level enforceAcl), not each descendant — a caller with write only on a directory root could rewrite ACLs arbitrarily deep into a subtree. Added a per-child check via a new checkAclSilent() helper (denied children are now counted in failureCount instead of aborting the whole operation, consistent with existing per-item error handling). 9. PathHandler.read() ignored Range/x-ms-range entirely, always streaming the full blob and never returning 206/Content-Range. Ported the same range-parsing/clamping logic BlobHandler.downloadBlockBlobOrAppendBlob already uses (deserializeRangeHeader + IExtentStore.readExtents), so DFS reads now support partial/resumable downloads like the Blob API. 10. Rename's destructive destination-delete happened before intermediate directory creation, unnecessarily widening the failure window where a crash could leave the destination path missing entirely. Reordered so the delete is the last step before the atomic rename when a destination exists (and skipped entirely — nothing destructive to do — when it doesn't, in which case only intermediate dirs are created). 11. setAccessControl let any caller with mere write access to a path reassign x-ms-owner, letting them grant themselves owner rights on future requests. Real ADLS Gen2 restricts ownership changes to the current owner or $superuser; added that check (only enforced when ACL mode + identity are active, matching how the rest of enforceAcl works). Added 4 new regression tests: Range/206 support (multiple ranges + beyond- EOF 416), and owner-reassignment denial/allowance in dfsAclIntegration. Not yet addressed (remaining Warnings, deferred as lower severity / larger scope): #7 (recursive delete concurrency-limited but ACL-recursive paging not unified with it — already correctly pages via continuation, noted as a documentation nit not a bug), #12 (TOCTOU between enforceAcl and the subsequent mutating call — accepted emulator limitation, same class as the already-documented append race), #13/#14 (named-group ACL / permission-model documentation nits), and SQL-portability Suggestions from the earlier persistence-layer review pass.

charset=UTF-8 Content-Transfer-Encoding: 8bit Closes out the review findings not addressed in the previous two commits. Documentation/doc-only fixes: - #12: documented the TOCTOU window between enforceAcl() and the mutating operation that follows it as an accepted emulator limitation, same class as the already-documented append-position race. - #13: (already covered by the earlier #6 fix — named-group ACL entries now log a warning when present-but-unevaluated.) - #14: documented in getRequiredPermission() that "setAccessControl" shares the same "w" permission bucket as ordinary writes, and that PathHandler.setAccessControl separately guards x-ms-owner reassignment specifically (the one case with real privilege-escalation risk) rather than the permission model distinguishing "write data" from "write ACL" in general. - #7: reviewed setAccessControlRecursive/delete's pagination — both already correctly page via continuation/marker; no action needed (the original finding was a documentation nit, not a bug). SQL portability fix (Suggestion): - SqlBlobMetadataStore's escapeLike()/likePrefixCondition()/ conditionalPrefixReplaceExpr() used '\' as the LIKE escape character, requiring MySQL/MariaDB-specific doubled-backslash handling that silently breaks if the target server runs with the NO_BACKSLASH_ESCAPES sql_mode (backslash stops being a string-literal metacharacter, so the doubled-escape clause becomes wrong). Switched the escape character to '^', which has no special meaning in any supported dialect's string literal syntax (sqlite/postgres/mysql/mariadb/mssql), eliminating the sql_mode dependency entirely and simplifying the code (no more per-dialect ESCAPE clause branching). Added a regression test renaming a directory whose name contains literal '%'/'_' characters, verifying an unrelated sibling blob that would spuriously match if those characters were misinterpreted as wildcards is left untouched. Verified: tsc --noEmit clean, eslint clean, DFS suite 70/70 passing (was 69 + 1 new), full @loki suite 642/642 passing (was 641 + 1 new). Note: the SQL escape-character change could not be verified against a live MySQL/MariaDB/MSSQL server in this environment (no such server available here); it was validated for syntactic consistency with the existing per-dialect quoting in the same file and the @loki test suite, but a maintainer with SQL-backend CI access should confirm the @sql suite still passes before merge. --- src/blob/dfs/DfsAclEnforcer.ts | 9 ++++ src/blob/dfs/handlers/PathHandler.ts | 8 ++++ src/blob/persistence/SqlBlobMetadataStore.ts | 43 ++++++++++--------- tests/blob/dfsProxy.test.ts | 45 ++++++++++++++++++++ 4 files changed, 84 insertions(+), 21 deletions(-) diff --git a/src/blob/dfs/DfsAclEnforcer.ts b/src/blob/dfs/DfsAclEnforcer.ts index af6ade79c..ae5622327 100644 --- a/src/blob/dfs/DfsAclEnforcer.ts +++ b/src/blob/dfs/DfsAclEnforcer.ts @@ -21,6 +21,15 @@ export type AclPermission = "r" | "w" | "x"; /** * Maps DFS operations to the minimum required permission. + * + * NOTE: "setAccessControl" returns "w" like ordinary data/property writes. + * Real Azure ADLS Gen2 treats changing a path's ACL as a stricter operation + * than writing data (in practice: owning user or superuser) — this emulator + * does not distinguish "write data/properties" from "write ACL" at the + * permission-level, but setAccessControl() additionally enforces an + * owner-or-$superuser check specifically for x-ms-owner reassignment (see + * PathHandler.setAccessControl) to avoid the most severe privilege-escalation + * case.
