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 like node.config.json to streamline flag management for testing and other experimental features, enhancing developer experience. Additionally, it includes updates to crypto 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. [FEATURE REQUEST] [V26.X] Node should run on Debian/Ubuntu-based images without having to manually install libatomic first: This issue addresses the problem that Node.js version 25.0.0 and later require the libatomic library, which is not pre-installed on common Debian and Ubuntu base images, causing runtime failures unless libatomic is manually installed. The user proposes that Node.js should either include libatomic or handle its installation to ensure seamless operation on these major Linux distributions without additional manual steps.

   • The comments discuss technical details about libatomic dependencies, compiler behaviors (GCC, Clang, Zig), and potential solutions including static linking libatomic or migrating to V8's custom libcxx; a pull request has been submitted to statically link libatomic for Linux Clang builds as a temporary fix, with urgency expressed due to the upcoming Node 26 LTS release and its impact on users relying on Debian/Ubuntu images.
   • Number of comments this week: 6

2. Abort "Lazy deopt after a fast API call with return value is unsupported" in Buffer.byteLength called from maybePrepareFinalChunk / res.end(string): This issue reports a process abort in Node.js v26.10.0 triggered by a "Lazy deopt after a fast API call with return value is unsupported" error occurring inside Buffer.byteLength when called from maybePrepareFinalChunk during res.end(string) with a large string payload. The problem appears under sustained, varied traffic on Linux CI runners running a Vite dev server, likely due to V8's current inability to handle deoptimization after fast API calls that return values, causing the Node.js process to terminate unexpectedly instead of gracefully deoptimizing.

   • The comments detail extensive reproduction attempts on Windows and Linux environments that fail to trigger the abort, suggesting the issue requires a long-running, polymorphic workload with memory pressure and optimized TurboFan code paths active. Diagnostics confirm the abort stems from V8's deliberate crash on lazy deoptimization after fast API calls returning values, with the recommended workaround being to avoid passing large strings directly to res.end by converting them to buffers first; contributors discuss potential Node-side mitigations and confirm the issue persists on the current main branch until V8 implements proper support.
   • Number of comments this week: 6

3. [META] ubuntu-slim runners time out after 15 mins while it usually takes <3 mins: This issue reports that GitHub Actions jobs running on the ubuntu-slim runner frequently time out after 15 minutes, whereas they typically complete in under 3 minutes on more powerful runners. The problem affects multiple workflows, including linting and build tasks, and discussions focus on potential solutions such as reverting to ubuntu-latest, migrating to ARM runners with more CPUs, adding caching, or reducing workload, but no definitive fix has been implemented yet.

   • Comments reveal ongoing troubleshooting with retries and observations of frequent timeouts on single-CPU runners; suggestions include reverting to more powerful runners or adding caching, though caching is limited by rate-limiting issues; cost and reliability trade-offs are debated, with some tests showing ARM runners improve success rates and reduce timeouts, but no consensus solution has been finalized.
   • Number of comments this week: 5

4. JSON.parse returns the wrong object key after an earlier sibling object with a "\\" key (v24.14.1): This issue describes a bug in Node.js v24.14.1 where JSON.parse incorrectly returns the wrong object key when parsing a JSON string containing sibling objects with escaped keys, specifically confusing a key with a single backslash and a key with an escaped quotation mark. The problem appears to be a regression in the V8 engine's JSON parser that causes it to treat distinct escaped keys as equal, leading to incorrect parsing results that differ silently from the input JSON.

   • The comments confirm the bug reproduces in v24.15.0 but not in earlier or later Node.js versions, indicating a V8 regression fixed in a later release; the fix was backported to v24.22.1, after which the issue no longer occurs, and the reporter is asked to verify the resolution in the latest release.
   • Number of comments this week: 4

5. [CONFIRMED-BUG] Missing html docs: This issue reports that the release builds and nightly builds of Node.js have stopped generating HTML documentation starting from version 26.11.0 and nightly version v27.0.0-nightly20260916bd2b98f549, likely due to a recent redesign. The discussion focuses on identifying the cause, confirming the regression slipped through existing checks, and proposing solutions including adding tests to catch missing docs earlier and potentially reverting the redesign changes on the main branch to restore documentation for upcoming releases.

   • The comments confirm the missing HTML docs began with a specific nightly build and link the issue to a redesign PR. They note that current CI checks do not verify the presence of HTML files, only the docs folder, and suggest adding tests to detect missing files earlier. The team discusses reverting the redesign on the main branch to ensure docs are available for the imminent Node.js 27 release, with plans to reintroduce fixes later.
   • Number of comments this week: 3

This section lists, groups, and then summarizes issues that were created within the last week in the repository.

Issues Opened This Week: 30

Summarized Issues:

• Process and Permission Aborts: Multiple issues describe Node.js process aborts triggered by permission system bugs and internal assertion failures. These include aborts caused by overlapping wildcard permission grants during process.permission.drop(), and crashes related to inspector subsystem callbacks lacking proper V8 HandleScope during exit. Such aborts highlight critical stability problems in permission handling and process shutdown sequences.
• [issues/66901, issues/66943, issues/66973]

• Memory Leaks and Retention: Several issues report memory leaks or retention bugs in Node.js components, including HTTP/2 sessions retaining idle timers after destruction, ffi subsystem leaks on macOS due to repeated dlopen failures, and WebAssembly JSPI stack memory not being unmapped on Linux x64. These leaks cause increased memory usage over time, impacting performance and resource management.
• [issues/66885, issues/67006, issues/67016]

• Filesystem Operation Bugs: There are multiple bugs affecting filesystem operations such as fs.mkdir hanging on procfs with recursive option, fs.cp() failing to replace dangling symlinks, fs.copyFile spinning on truncated source files, and fs.rmSync returning prematurely without deleting directories under concurrent modifications. These issues cause hangs, incorrect error returns, or incomplete file operations.
• [issues/66890, issues/66934, issues/66946, issues/67010]

• Module and Loader Regressions: Node.js module loading and linking regressions include a performance regression in SourceTextModule linker causing quadratic relinking, and a regression where module.registerHooks() with resolve hooks breaks CommonJS loading via require.extensions. These regressions degrade module loading performance and cause syntax errors in TypeScript files.
• [issues/66938, issues/66998]

• Buffer and Stream Handling Issues: Bugs in buffer and stream APIs include incorrect clamping of byteOffset in Buffer.indexOf and includes for buffers larger than 2 GiB, and fs.createReadStream ignoring setDefaultHighWaterMark settings, continuing to use a fixed buffer size. These issues cause incorrect search results and inconsistent stream buffer sizing.
• [issues/66937, issues/67008]

• Child Process and Forking Problems on macOS: Issues on macOS involve child processes created by fork() aborting during exit due to Mach semaphore destruction failures, and fs.copyFile hanging due to source truncation. These problems stem from platform-specific resource handling and cause process crashes or hangs.
• [issues/66933, issues/66934]

• Cryptographic and Randomness Behavior: The cryptographic random functions continue from a saved deterministic state after snapshot or checkpoint restore, requiring applications to reseed to avoid repeated outputs. This behavior is inherited from OpenSSL's deterministic random bit generator and needs clearer documentation.
• [issues/66880]

• Environment Variable Handling Regression: Since Node.js v26.11.0, reassigning process.env and spawning child processes without specifying options.env causes child processes to receive the OS environment instead of the reassigned environment, breaking environment variable overrides. This regression leads to inconsistent child process environments compared to previous versions.
• [issues/66882]

• Build and Compilation Issues: Problems in the build system include cross-compilation of Rust archives mixing host and target archives incorrectly, and a Linux From Scratch compilation failure due to ICU character encoding check failure. These issues cause build failures or incorrect artifact placement.

• [issues/66951, issues/66981]

• JSON Parsing and URL Parsing Bugs: Bugs include JSON.parse returning incorrect keys due to escaped backslash sequences causing key confusion, and URL.canParse intermittently returning false for valid URLs with non-ASCII hosts in older Node.js versions. These parsing issues cause silent data corruption or inconsistent URL validation.
• [issues/66916, issues/67012]

• Zip and Archive Handling Bugs: The ZipProvider.rename() method silently overwrites files when renaming directories onto nonempty destinations without rollback, and a test failure occurs due to zipinfo utility mangling non-ASCII filenames without UTF-8 support. These issues cause data loss or test failures related to archive handling.
• [issues/66972, issues/66975]

• FFI Subsystem Bugs: The ffi subsystem has multiple bugs including silent creation of void callbacks when arguments are reversed, rejection of valid -0 integer arguments before optimization, and memory leaks on macOS due to retained native memory from repeated dlopen failures. These bugs cause incorrect native interop behavior and resource leaks.
• [issues/66996, issues/67006, issues/67033]

• Worker Thread Memory Limit Overrides: Programmatically set memory limits for worker threads are overridden by global process flags like --max-old-space-size, preventing intended heap size containment within workers and causing unexpected memory behavior.
• [issues/67014]

• Heap Memory Inquiry: A user inquiry about a potential heap memory problem in Node.js version 22.23.4 is noted without further details or resolution.
• [issues/67034]

2. sqlite: tidy up handle ownership and lifetimes: This pull request tidies up handle ownership and lifetimes in the SQLite integration by centralizing statement tracking within the Statement constructor, replacing custom deleters with a unified DeleteFnPtr for all SQLite handles, consolidating BackupJob cleanup through a single Settle() method to prevent leaks, and caching the SQLTagStore constructor template on the environment to optimize prototype sharing.

• URL: pull/66912

• Associated Commits: b0694, 52e05, 9ad23, b8409

3. url: use indexed appends in search params getAll: This pull request improves the performance of the URLSearchParams.getAll() method by replacing primordial push calls with indexed appends when collecting matching query parameter values, resulting in significantly higher throughput and no change in result order, as demonstrated by local benchmarks on Apple M2/macOS with V8 15.6.

• URL: pull/66872

• Associated Commits: 74a74, 2f1f9, 5fff1

Other Open Pull Requests

• Zlib performance improvements: Multiple pull requests enhance zlib convenience methods by optimizing buffer handling and stream usage. One PR grows the output buffer dynamically during large asynchronous decompression calls to reduce threadpool round trips, while another bypasses Transform stream creation in synchronous methods to reduce memory allocations and improve performance without changing behavior.
  [pull/66863, pull/66864]

• HTTP and HTTP/2 socket and session handling: Improvements include releasing or unreferencing sockets of unread HTTP responses to prevent sockets from keeping the process alive unnecessarily, and fixing HTTP/2 session destruction by clearing timeouts and listeners to avoid idle timers retaining sessions. These changes ensure proper resource cleanup and timely process exit.
  [pull/66865, pull/66886]

• EventEmitter and utility function optimizations: The EventEmitter.eventNames() method is optimized by using indexed appends for better performance, and the hexSlice function used in util.inspect() is simplified by exporting it directly from internal/buffer to reduce prototype pollution risks. Both changes improve internal efficiency and safety.
  [pull/66875, pull/66974]

• Test runner and coverage improvements: The test runner is enhanced to forward command-line arguments after -- directly to test files and to merge coverage data using a range-tree merge instead of a set-based merge. These fixes address argument forwarding issues and ensure uncovered nested blocks are correctly retained across processes.
  [pull/66911, pull/66873]

• Reverts fixing AsyncLocalStorage regression: Two pull requests revert previous commits that changed how parked TransformStream writes were handled, which caused regressions in AsyncLocalStorage propagation within transform() and flush() methods. The reverts restore original behavior to maintain compatibility and pass all relevant tests.
  [pull/66913, pull/66914]

• Filesystem fixes and backports: A backport fixes recursive fs.mkdir to prevent endless retries on ENOENT errors for existing parent directories like /proc, including regression tests for nested /proc paths. Another fix ensures fs.rmSync correctly handles entries removed by other processes during recursive deletion, preventing silent failures.
  [pull/66927, pull/67011]

• Module linking optimization: The module linking process in the Node.js VM is improved by tracking and skipping already linked modules during a single link() call. This prevents redundant linking and reduces quadratic growth in linker calls, addressing issue #66938.
  [pull/66942]

• OpenSSL concurrency regression test: A regression test is added to ensure concurrent first use of OpenSSL, specifically decoding an RSA-PSS certificate while other threads initialize OpenSSL, does not cause the previously observed decode failure fixed by a revert. This test prevents recurrence of ERR_OSSL_EVP_DECODE_ERROR.
  [pull/66966]

• QUIC internal error and crypto error fixes: Fixes include correcting internal error code conversion by replacing NGTCP2_INTERNAL_ERROR with NGTCP2_ERR_INTERNAL to properly report internal failures, and refining QUIC crypto error classification to decode only transport namespace errors as TLS alerts. These changes add regression tests and improve compliance with RFC 9000 and RFC 9001.
  [pull/66967, pull/66968]

• ZipProvider rename method validation: The ZipProvider.rename() and renameSync() methods are improved by adding validation to prevent directory renames from merging into non-empty directories or overwriting regular files, returning appropriate errors. The implementation also ensures all members are read before writing during renames to avoid partial writes, with comprehensive tests added.
  [pull/66976]

• Security changelog updates: Changelogs for Node.js versions v22.23.4 and v24.22.1 are updated to include CVE-2026-106072, documenting the security fix that rejects non-canonical IP addresses in alignment with the security advisory and the existing v26.12.1 changelog.
  [pull/66984]

• Child process environment inheritance fix: A regression fix ensures that spawning child processes without specifying options.env correctly inherits changes made by reassigning process.env. The environment handling logic now detects if process.env is the native proxy and falls back to copying the environment object when it is not, preserving expected behavior.
  [pull/66883]

• Snapshot builder crash fix and storage binding: Fixes a crash in the snapshot builder caused by web storage binding not registering C++ callbacks as external references. It also ensures creating localStorage or sessionStorage during snapshot creation throws an error and adjusts option handling to honor runtime flags and warnings correctly.
  [pull/66884]

• Readable stream fractional limit fixes: The behavior of Readable.prototype.take() and Readable.prototype.drop() is corrected by truncating fractional limits toward zero before range checking. This ensures compliance with the iterator helpers specification and prevents off-by-one errors when fractional limits are used.
  [pull/66888]

• Timer mock fix for running all timers: The t.mock.timers.runAll() function is fixed to correctly execute the longest scheduled timer by updating the priority queue's peek method to identify the largest timer among heap leaves rather than assuming the last element is largest. A regression test verifies this fix.
  [pull/66896]

• X.509 certificate chain cloning improvements: Cloning of X.509 certificate chains across isolates in crypto and TLS modules is improved by snapshotting leaf and peer certificates as DER data and parsing separate native certificates in each isolate. This enables iterative construction of JavaScript chains for TLS inspection, structuredClone(), MessagePort, and workers, ensuring each certificate position has its own object.
  [pull/66898]
