I. News

1.1 Recent Version Releases:

The current version of this repository is v23.10.0

1.2 Version Information:

Released on March 13, 2025, this version introduces the --experimental-config-file feature, allowing developers to use JSON configuration files to simplify running tests and managing numerous flags, enhancing developer experience. Additionally, it includes updates to root certificates, new TLS and V8 methods, improved error handling, and various tooling and documentation enhancements.

II. Issues

2.1 Top 5 Active Issues:

We consider active issues to be issues that that have been commented on most frequently within the last week. Bot comments are omitted.

1. test_runner: child process exits 0xC0000005 on Windows after its tests pass: This issue describes an intermittent problem on Windows where a child process running test files under the Node.js test runner crashes with an access violation (0xC0000005) after all tests in the file have passed, causing the file to be incorrectly reported as failed. The crash only occurs with the default test isolation mode that runs tests in child processes, does not reproduce with --test-isolation=none, and appears to be related to the child process lifecycle or teardown rather than the tests themselves, with stress testing showing the issue persists on Node.js v24.19.0 and v24.20.0 but not on v26.8.1 so far.

   • The comments detail attempts to reproduce and narrow down the issue, including stress testing across multiple Node.js versions and isolation modes, confirming the crash is tied to the child process isolation path rather than generic process spawning, and proposing further tests to isolate the problem to the runner’s process-isolation plumbing.
   • Number of comments this week: 7

2. [META] ubuntu-slim runners time out after 15 mins while it usually takes <3 mins: This issue describes a problem where GitHub Actions jobs running on the ubuntu-slim runners are timing out after 15 minutes, whereas they typically complete in under 3 minutes on other runners. The timeouts are causing significant disruptions in the continuous integration process, leading to failed merges and difficulties in maintaining a green CI status, with discussions focusing on whether to revert to ubuntu-latest runners or implement caching to mitigate the problem.

   • The comments reveal that the timeouts are intermittent but frequent, affecting multiple workflows and likely related to the single CPU limitation and 15-minute usage cap of ubuntu-slim runners. Contributors discuss potential solutions including reverting to ubuntu-latest, adding caching to speed up jobs, and acknowledging that the issue may stem from GitHub Actions infrastructure changes, with no immediate fix apparent.
   • Number of comments this week: 6

3. Feature request: per-async-context current working directory (AsyncLocalStorage-aware chdir/cwd): This issue requests a feature to enable a per-async-context current working directory in Node.js, addressing the problem that process.chdir() currently changes the global working directory for the entire process, which causes conflicts when multiple asynchronous tasks run concurrently. The proposal suggests making process.cwd() and process.chdir() respect an AsyncLocalStorage-based override or adding a scoped API to isolate working directories per async context, improving use cases like per-request build tools and sandboxing without spawning child processes.

   • The comments discuss the technical feasibility and design considerations of making process.chdir() async-context aware, with one user explaining the practical motivation from their project and clarifying that the underlying syscall cannot be scoped but the JS layer can; another user expresses skepticism about acceptance and suggests exploring the experimental Virtual File System API as an alternative.
   • Number of comments this week: 6

4. fs: fs.link() on exFAT volumes (Windows) fails with misleading EISDIR instead of "not supported": This issue reports that on Windows systems, the fs.linkSync() function fails with a misleading EISDIR error when attempting to create hard links on exFAT volumes, which do not support hard links. The underlying Windows error is ERROR_INVALID_FUNCTION, but Node.js incorrectly translates this to EISDIR, causing confusion for developers; the issue requests a more accurate error mapping to reflect the unsupported operation.

   • The comments show a contributor volunteering to investigate and fix the error translation by tracing the Windows error through libuv to Node.js, with the original reporter providing detailed test data for validation. The contributor acknowledges and corrects a misunderstanding about the contribution process, commits to focusing on this issue exclusively, and plans to submit a fix and regression test for review and re-testing on exFAT volumes.
   • Number of comments this week: 6

5. [QUIC] [WEBTRANSPORT] quic: is stream priority compatible to w3c webtransport sendgroups ?: This issue discusses whether the current QUIC stream priority implementation in Node.js is compatible with the W3C WebTransport sendGroup mechanism, highlighting that the existing priority system differs significantly from the W3C specification. It explores the challenges of aligning these priorities due to architectural differences, the need for upstream changes in ngtcp2, and proposes a potential unified approach to local scheduling priorities across HTTP/3, WebTransport, and QUIC streams.

   • The comments reveal attempts to implement alignment via a numeric sendOrder option, which was ultimately closed due to incompatibilities and missing upstream support for sendGroups. Further discussion clarifies the distinction between HTTP/3 priority signaling and WebTransport local scheduling, suggesting a simplified API approach focusing on local scheduling priorities and deferring full alignment until upstream libraries support necessary features.
   • Number of comments this week: 4

2.2 Top 5 Stale Issues:

2.4 Closed Issues

This section lists, groups, and then summarizes issues that were closed within the last week in the repository. This section also links the associated pull requests if applicable.

Issues Closed This Week: 29

Summarized Issues:

• Zip File Archive Support: This issue proposes adding native support in Node.js for basic manipulation of zip file archives, including reading directory listings, accessing files, and adding files within archives. The goal is to provide a more efficient, secure, and cross-platform alternative to existing userland implementations and third-party dependencies.
  • issues/45434

• Port Binding Race Condition in Clustered Environment: A race condition occurs in Node.js clustered environments when binding a second server to a recently closed port, intermittently causing an EADDRINUSE error despite the port being reported as free. This issue is especially prevalent under CPU load and complicates server restarts within the same cluster worker.
  • issues/53738

• Test Failures and Flakiness on Specific Platforms: Several issues describe flaky or failing tests on specific platforms or configurations, including a parallel test-runner-coverage failure on Windows ARM64 due to falsy coverage values, and WASI pthread test failures caused by assertion errors leading to unexpected process termination.
  • issues/55154, issues/64226

• Mock Module API Simplification: A proposal suggests consolidating the separate defaultExport and namedExports options in mock.module into a single exports option to align with other testing frameworks. This includes plans for deprecation, migration support, and eventual removal of the old options to simplify the API.
  • issues/58443

• Filesystem Encoding and Case Sensitivity Issues: Problems exist with fs.mkdtemp always returning strings even when given non-UTF8 Buffer prefixes, causing encoding issues, and with fs.glob on Windows preserving original pattern casing instead of actual filesystem casing, leading to case-sensitive exclude pattern failures. A proposal includes making case sensitivity configurable.
  • issues/58795, issues/58991

• Event Loop Blocking Attribution and Live Lock Issues: There is a need for supported methods to identify asynchronous callbacks causing event loop blocking, as current reliance on async_hooks.createHook() is discouraged. Additionally, the locks.request mechanism can cause live locks or high event loop utilization, prompting replacement with user-land solutions using SharedArrayBuffer and Atomics.
  • issues/60169, issues/62644

• V8 Engine and Memory-Related Crashes: Issues include a fatal V8 crash on Windows triggered by Unicode-escaped direct eval followed by a function expression, and a worker thread termination due to out-of-memory conditions in V8 version 14.6 during wasm allocation tests, highlighting changes in V8 behavior causing unexpected process aborts.
  • issues/63067, issues/62870

• SQLite Enhancements and Bugs: Proposals and bugs involve enabling the "decimal" extension in SQLite builds to support decimal math operations, refactoring tests to use in-memory databases for speed, and a bug where user-supplied JavaScript getters cause segmentation faults during option retrieval in DatabaseSync methods.
  • issues/63119, issues/64665, issues/65586

• CommonJS Named-Exports Detection API Proposal: A proposal suggests adding an API to expose CommonJS named-exports detection internally in Node.js, allowing frameworks to avoid depending on external packages like cjs-module-lexer and simplifying integration when loading CJS modules from ESM.
  • issues/63123

• Integration and Validation Issues Related to User Edgarruiz8585: Two issues report problems related to integration and validation involving the user Edgarruiz8585, though details are limited to the identification of the problem and user involvement.
  • issues/63787, issues/63788

• Stream Iterator Helpers Not Destroying Source Stream: The readable.find(), some(), and every() stream iterator helpers fail to destroy the source stream upon a match if the stream has not ended, causing the stream to remain open and potentially leak resources in long-lived or never-ending streams.
  • issues/64261

• URLPattern API Dictionary Member Access Issues: The URLPatternInit conversion accesses and exposes dictionary members in an incorrect order and includes absent members as enumerable properties with undefined values, deviating from expected WebIDL dictionary semantics.
  • issues/64780

• Use-After-Free Bug in CleanupHookThunkRun: A use-after-free bug occurs during environment teardown for every node::ObjectWrap instance still alive, caused by redundant removal of cleanup hooks leading to invalid memory reads.
  • issues/65195

• Permission Audit Mode Enforcement Inconsistencies: The --permission-audit flag unexpectedly enforces permission checks such as on lstat, symlink, and dlopen operations instead of merely auditing them, resulting in different behavior compared to normal execution and causing confusion.
  • issues/65419

• FFI Memory Helper Silent Failures: FFI memory helper functions return undefined instead of throwing errors when required arguments are omitted, leading to silent failures and inconsistent behavior across these helpers.
  • issues/65499

• Unreproducible Builds with --shared Flag: Building Node.js version 24.19.0 twice with the --shared flag on Linux Debian results in small but consistent binary differences in libnode, indicating unreproducible builds caused by prior changes.
  • issues/65508

• Mutual-TLS getPeerCertificate Regression: A regression in Node.js v26.8.0 causes getPeerCertificate(true) to return only the leaf certificate without the full client certificate chain during mutual-TLS connections, due to caching interactions triggered by internal use of getPeerX509Certificate().
  • issues/65579

• Aligned Buffer Pool RangeError Regression: A regression introduced in Node.js 26.8.0 causes RangeError exceptions when creating multi-byte typed-array views without explicit lengths, due to increased backing ArrayBuffer size in the aligned Buffer pool, breaking previously working functionality.
  • issues/65601

• Platform-Specific Test Failures and Watcher Bugs: The fs-watch-recursive-delete-race test fails consistently on AIX due to ENODEV errors, and on Windows, deleting a directory being watched by fs.watch() causes an unbounded flood of rename events at high rates instead of proper error handling, leading to excessive CPU usage.
  • issues/65697, issues/65837

• Child Process execArgv Option Ignored: The execArgv option passed to child_process.spawn() is silently ignored, unlike fork(), causing flags like --jitless to not take effect in spawned child processes despite documentation suggesting otherwise.
  • issues/65725

• Agent Friendly Score Badge Addition: A proposal to add an Agent Friendly score badge to the Node.js README to publicly display its score of 84.4 out of 100 for agent friendliness.
  • issues/65816

Other Closed Pull Requests

• Filesystem module Buffer prefix fix: This pull request fixes an issue in the Node.js filesystem module where passing a Buffer as the prefix to the mkdtemp functions incorrectly returned a string, potentially corrupting non-UTF8 paths. It ensures the encoding option is forced to 'buffer' when a Buffer prefix is detected across asynchronous, synchronous, and disposable versions.
  • pull/64397

• V8 heap profiling API addition: This pull request introduces the v8.setHeapProfileNearHeapLimit(limit) API to the V8 engine, enabling the writing of an active sampling heap profile to disk when the heap approaches its limit. This complements existing heap snapshot functionality and requires prior heap profiling activation via v8.startHeapProfile() or the --heap-prof CLI option.
  • pull/64676

• Crypto module FIPS indicator and enforcement: This pull request introduces a FIPS indicator diagnostics channel and a strict enforcement mode to Node.js's crypto module. It enables users to observe when non-FIPS-approved operations occur with OpenSSL FIPS providers and optionally reject such operations at runtime via new flags without impacting existing defaults or performance.
  • pull/65645

• SQLite undefined binding fix: This pull request addresses the issue of binding undefined values in SQLite by converting them to null, thereby fixing the related problem reported in the Node.js repository.
  • pull/62008

• Native addons loading from virtual file system: This pull request enables loading native addons from a mounted virtual file system by reading the addon's bytes directly from the VFS and loading them into a private, self-cleaning image using platform-specific minimal on-disk footprints. This overcomes the limitation that dlopen() and LoadLibrary() require a real file system path with an inode.
  • pull/65680

• Contributor guidance workflow improvements: This pull request refines the contributor guidance workflow by using the Node.js GitHub bot token for association checks, independently routing welcome and caution messages, and ensuring all outside contributors are processed through agentscan with appropriate labeling to support moderation efforts.
  • pull/65745

• Fixes for flaky tests in CI pipeline: This pull request addresses and fixes six recurring flaky tests in the Node.js continuous integration pipeline by root-causing each failure and applying targeted test code changes.

  • pull/65780

• PerformanceResourceTiming attribute additions: This pull request adds missing PerformanceResourceTiming attributes and updates the responseStart getter to align with the Resource Timing specification. It also includes these new getters in the toJSON() output, updates Web Platform Tests status, and provides comprehensive tests and documentation.
  • pull/65017

• QUIC implementation refactor for TLS handshake: This pull request refactors the QUIC implementation to reuse the generic TLS handshake suspension mechanism from node:tls, eliminating the previous event deferral system. It restructures ALPN and SNI resolution to precalculate values at the suspend point, enhancing handshake flow clarity and enabling future features without altering existing behavior outside node:quic.
  • pull/65522

• V8 engine backport attempt: This pull request attempts to backport several V8 engine commits focused on optimizing stack frame handling and stack trace summarization to address a specific Node.js issue, but it was not merged.
  • pull/65764

• V8 sandbox build support: This pull request implements support for building Node.js with the V8 sandbox enabled by refactoring memory allocation to ensure all ArrayBuffer backing stores are allocated inside the sandbox’s memory cage. It introduces a unified method to adopt or copy memory into the sandbox and adjusts various subsystems to comply with sandbox constraints.
  • pull/62237

• IPv6 loopback recognition fix: This pull request updates the isLoopback function to correctly recognize bare IPv6 loopback addresses (::1 and 0:0:0:0:0:0:0:1) in addition to bracket-wrapped forms, ensuring it returns true regardless of whether the IPv6 address includes brackets.
  • pull/63619

• Stream read/write performance optimization: This pull request optimizes stream read and write operations by allocating read buffers from a shared 64KB slab to eliminate per-read allocations and map bookkeeping. It also creates WriteWrap objects lazily only when writes do not complete synchronously, improving performance and reducing memory overhead.
  • pull/64455

• Collaborator automation documentation: This pull request documents procedures and best practices for collaborators using automation tools such as the commit queue, fast-track, stale automation, and saved triage views. It also clarifies the semantics of the needs-ci label and expectations for reviewer follow-through.
  • pull/65671

• Experimental Hybrid KEMs in Web Crypto API: This pull request adds experimental Hybrid Key Encapsulation Mechanisms (KEMs) to the Web Cryptography API in Node.js, enabling support for algorithms like MLKEM768-X25519 under non-FIPS conditions. Future plans include replacing the current JavaScript composition once OpenSSL provides native support.
  • pull/65759

• SQLite virtual tables support: This pull request introduces support for SQLite virtual tables by adding a new database.createModule(name, options) method that wraps the sqlite3_create_module_v2() API. It allows users to create read-only virtual tables backed by JavaScript data sources with configurable columns, rows, and usage options, ensuring type validation and SQL injection protection.
  • pull/61544

• HTTPS proxy CONNECT header size enforcement: This pull request enforces the maximum HTTP header size limit when reading HTTPS proxy CONNECT responses, optimizes the use of readable listeners to prevent unbounded buffer growth, and adds regression tests for fragmented or incomplete proxy response headers.
  • pull/64545

• ZipProvider virtual filesystem implementation: This pull request introduces a new node:vfs provider called ZipProvider, which uses a node:zlib ZIP archive to expose the archive's contents as a virtual filesystem tree. It supports explicit and implicit directories, read-only or writable modes, asynchronous and synchronous operations, and includes disposal methods for resource management.
  • pull/64915

• Inspector JavaScript execution deferral: This pull request defers JavaScript execution triggered by V8 interrupts in the Node.js inspector by dispatching inspector messages using a microtask to preserve timing contracts. It also enables a V8 API feature that restricts executing JavaScript during interrupt callbacks, primarily affecting addons using v8::Isolate::RequestInterrupt.
  • pull/65397

• Build-tarball.yml updates and revert: This pull request involves updates to the build-tarball.yml file, including changes referenced by the identifier TZAHAL 18520, but it was not merged and includes commits that both apply and revert these updates.
  • pull/65824

• Remove doc-only target on riscv64: This pull request removes the doc-only target from the default make test-ci process on riscv64 systems to prevent various documented failures, aligning this behavior with previous adjustments made for AIX and IBMi platforms.
  • pull/62251

• REPL inline syntax highlighting: This pull request introduces inline syntax highlighting to the Node.js REPL by using the Acorn tokenizer to colorize JavaScript input in real-time with distinct colors for keywords, strings, numbers, regular expressions, and comments. The underlying text remains plain and the feature can be disabled via configuration or environment variables.
  • pull/64609

• Builtin code cache API for embedders: This pull request introduces a new public API allowing embedders who create contexts and environments without Node.js's built-in snapshot to supply a precompiled builtin code cache. This improves startup performance by enabling processes to use a cached compilation of builtins instead of compiling from source each time, with flags and tests to generate, supply, and control the cache.
  • pull/65352

• fs.cp() performance and correctness improvements: This pull request improves the fs.cp() and fs.promises.cp() functions by moving the directory tree walk from a JavaScript-based sequential process to a single C++ thread pool operation using the existing fs.cpSync() implementation. This results in significantly faster copy performance, correct preservation of source directory permissions, enhanced error handling, and consistent behavior with special file types and symbolic links.
  • pull/65488

• SQLite connection validation fix: This pull request addresses a bug in the SQLite integration by adding a validation step to ensure the database connection remains open after reading options. This prevents segmentation faults and memory errors caused by operations running on a closed connection.
  • pull/65591
