[v24.x backport] perf_hooks: sample delay per event loop iteration by pabloerhard · Pull Request #64480 · nodejs/node

pabloerhard · 2026-07-13T19:35:43Z

Add a samplePerIteration option to monitorEventLoopDelay that records event loop delay from libuv event loop iterations instead of the timer interval sampler. The default remains interval-based; existing uses of monitorEventLoopDelay() keep behaving the same unless the samplePerIteration option is passed through.

Replace the O(n) case-insensitive algorithm-name scan with an O(1) SafeMap lookup. The map is pre-built at module init alongside kSupportedAlgorithms. Hoist the opts object literal used in normalizeAlgorithm to module level to avoid allocating identical { prefix, context } objects on every call. Pre-compute ObjectKeys() for simpleAlgorithmDictionaries entries at module init to avoid allocating a new keys array on every normalizeAlgorithm call.

Replace object spread in nested WebIDL conversion options with stable-shape ordinary objects. This keeps hot dictionary and sequence conversion paths from allocating null-prototype spread results. Apply the same pattern to Web Crypto converter wrappers that override allowResizable or enable [EnforceRange].

This function call can fail with `Z_VERSION_ERROR` if the compiled library vs loaded library mismatched in version number or in stream structure size. In those cases, zlib doesn't initialize the `strm_.msg` field to null. Therefore, when a `CompressionError` object is created via `ErrorForMessage()`, it can read a stale or uninitialized `strm_.msg` pointer that will cause a crash. Example ASAN report: ``` AddressSanitizer: SEGV on unknown address #0 __strlen_avx2 string/../sysdeps/x86_64/multiarch/strlen-avx2.S:76 nodejs#1 strlen (/work/node/out/Debug/node+0x1a42ab7) nodejs#2 v8::(anonymous namespace)::StringLength(char const*) /work/node/out/../deps/v8/src/api/api.cc:7581:16 nodejs#3 v8::(anonymous namespace)::StringLength(unsigned char const*) /work/node/out/../deps/v8/src/api/api.cc:7587:10 nodejs#4 v8::String::NewFromOneByte(v8::Isolate*, unsigned char const*, v8::NewStringType, int) /work/node/out/../deps/v8/src/api/api.cc:7677:3 nodejs#5 node::OneByteString(v8::Isolate*, char const*, int, v8::NewStringType) /work/node/out/../src/util-inl.h:166:10 nodejs#6 node::(anonymous namespace)::CompressionStream< node::(anonymous namespace)::ZlibContext> ::EmitError(node::(anonymous namespace) ::CompressionError const&) /work/node/out/../src/node_zlib.cc:565:7 nodejs#7 node::(anonymous namespace)::CompressionStream< node::(anonymous namespace)::ZlibContext> ::CheckError() /work/node/out/../src/node_zlib.cc:519:5 nodejs#8 node::(anonymous namespace)::CompressionStream< node::(anonymous namespace)::ZlibContext> ::AfterThreadPoolWork(int) /work/node/out/../src/node_zlib.cc:543:10 nodejs#9 node::ThreadPoolWork::ScheduleWork() ::'lambda'(uv_work_s*, int) ::operator()(uv_work_s*, int) const /work/node/out/../src/threadpoolwork-inl.h:57:15 nodejs#10 node::ThreadPoolWork::ScheduleWork() ::'lambda'(uv_work_s*, int) ::__invoke(uv_work_s*, int) /work/node/out/../src/threadpoolwork-inl.h:48:7 nodejs#11 uv__work_done /work/libuv-1.51.0/src/threadpool.c:330:5 nodejs#12 uv__async_io.part.0 /work/libuv-1.51.0/src/unix/async.c:208:5 ``` Signed-off-by: ndossche <[email protected]> PR-URL: nodejs#63476 Reviewed-By: Anna Henningsen <[email protected]>
