Pull request overview

This PR primarily updates Azurite’s JS/TS codebase and test suite to align with newer Azure SDK behaviors (credential access, header casing, and Uint8Array usage), and adjusts the Blob swagger/generated artifacts to remove the default for x-ms-blob-sequence-number.

Changes:

Upgrade/adjust Azure SDK dependencies and update tests to match new SDK response/option shapes.
Standardize binary handling toward Uint8Array across blob code paths and tests.
Remove the swagger/generated default value for the BlobSequenceNumber header parameter.

restoreUint8Array no longer handles legacy persisted Buffer JSON shapes (e.g. { type: "Buffer", data: [...] }) and will mis-restore those objects (treating only type/data keys as array indices). Since Azurite may load existing Loki metadata created by older versions, please keep backward-compat support (handle obj instanceof Uint8Array, obj instanceof Buffer, and the {type:"Buffer",data} form) before falling back to the numeric-key object case.

    if (chunk) this.bodyText += (chunk! as any).toString();
    this.subResponse.end();
+    return this;


SubResponseTextBodyStream.end(...) overrides Writable.end but doesn't delegate to super.end(...) or invoke the optional callback. This can break expected stream semantics (e.g., finish events / callback-based completion) and may cause hangs if any caller relies on the callback. Consider calling super.end(chunk as any, encoding as any, cb as any) and only then notifying subResponse.end() (or wrapping it in the callback).

Suggested change

if (chunk) this.bodyText += (chunk! as any).toString();

this.subResponse.end();

return this;

let finalChunk = chunk;

let finalEncoding = encoding;

SimpleTokenCredential is importing TokenCredential/AccessToken/GetTokenOptions from @azure/identity, but this helper only needs the core auth types. Prefer importing these types from @azure/core-auth (already present in devDependencies) to avoid adding a heavyweight identity dependency just for typings.

The shared-key string-to-sign header order looks incorrect: Content-Language is currently appended before Content-Encoding. For Azure Storage SharedKey auth, the canonical string should include Content-Encoding before Content-Language. Swapping these will cause signature mismatches whenever either header is present.

src/blob/persistence/LokiBlobMetadataStore.ts:3121

restoreUint8Array no longer handles values persisted in the common JSON form { type: "Buffer", data: [...] } or values that are already Uint8Array. If existing Loki DB files contain this representation, the current implementation will treat {type,data} as a 2-byte array and corrupt MD5 restoration. Please re-add handling for obj instanceof Uint8Array and for obj.type === "Buffer" (using obj.data) to maintain backward compatibility.

  private restoreUint8Array(obj: any): Uint8Array | undefined {

These assertions hardcode st=/se= timestamps that depend on the local timezone because startDate/endDate are constructed with new Date(year, month, ...) (local time). This makes the expected SAS string non-deterministic across environments. Consider using UTC construction (e.g. new Date(Date.UTC(...)) or an ISO ...Z string) so the expected query parameters are stable on CI and developer machines.

This file has been fully commented out, leaving a large block of dead code in the repository. If the test needs to be disabled, prefer describe.skip(...) with a short explanation, or delete the file entirely if it's no longer relevant. Keeping hundreds of lines commented makes maintenance and future debugging harder.

- Uncommented overrideRequest function in tests/testutils.ts - Fixed type annotation from StorageServiceClient to any for compatibility - Resolves remaining 6 TypeScript compilation errors - All tests now compile and run successfully

- Update xml2js direct dependency to 0.6.2 (latest) - Add overrides for vsce and azure-storage to use xml2js ^0.5.0 - Eliminates vulnerable xml2js <0.5.0 in dependency tree - Reduces package-lock.json size by 45% through deduplication - All tests pass, no breaking changes

computeHMACSHA256() currently copies the key buffer (new Uint8Array(key)) before hashing. Node's createHmac accepts Buffer directly, so this extra allocation/copy is unnecessary and will add overhead on hot paths (auth/SAS signing).

restoreUint8Array() no longer handles the common JSON-serialized Buffer form ({ type: "Buffer", data: [...] }). If Loki persists or reloads buffers in that shape, this loop will throw because it expects numeric keys.

overrideRequest() now takes service: any, which loses type safety for a helper that monkeypatches _buildRequestOptions. Since this is only used with azure-storage services, consider importing a type-only service interface (or defining a minimal local interface for _buildRequestOptions / __original_buildRequestOptions) to keep compile-time checking without pulling runtime deps.

This test now relies on the global AbortController (no longer imported).

tedious was bumped to ^18.x, but this major line requires newer Node runtimes (package metadata indicates node >=18), and it also pulls in newer Azure deps that require even higher Node versions. With engines.node still set to >=10.0.0, installs/runs on older Node versions will likely break. Please either bump engines.node (and related @types/node/tooling) accordingly or pin tedious (and other deps) to versions compatible with the supported Node range.

 export async function getMD5FromString(text: string): Promise<Uint8Array> {
-  return createHash("md5").update(text).digest();
+  return createHash("md5").update(text).digest() as any;
 }


getMD5FromString() returns digest() as any. Since digest() returns a Buffer (which is already a Uint8Array), you can avoid both any and extra copies by returning it with a type-safe cast (or by changing the return type to Buffer).

+      } as any;


This test patches global.Uint8Array to assert on allocation behavior. Overriding a global built-in is brittle and can introduce flakiness if any other code executed during the test constructs a Uint8Array (including unrelated library internals). Consider removing the global patch and asserting performance characteristics via more targeted instrumentation/benchmarks.

readIntoString() now copies every chunk via Uint8Array.from(...). The chunks yielded by a Node readable are already Buffer/Uint8Array, and Buffer.concat accepts Uint8Array[], so this introduces unnecessary allocations. Consider pushing chunk as Uint8Array (or Buffer.from(chunk as any) only when needed) to avoid the per-chunk copy.

chunks.push(Uint8Array.from(chunk as Buffer));

chunks.push(chunk as Uint8Array);

SubResponseTextBodyStream.end() overrides Writable.end() but never calls super.end(...) and ignores the encoding/cb parameters. This can prevent the stream from reaching the finished state and can break callers that rely on the callback/finish event. Consider delegating to super.end(...) and triggering subResponse.end() in the completion path.

+    if (obj instanceof Buffer) {
+      return new Uint8Array(obj);
    }

    const length = Object.keys(obj).length;


restoreUint8Array() no longer handles the common JSON shape produced when a Buffer is serialized ({ type: "Buffer", data: [...] }). In that case this method will treat the object keys (type, data) as bytes and return incorrect data. Please re-add handling for the { type: "Buffer", data } form (and ideally keep the fast-path for Uint8Array inputs).
