v8 learns to serialize X509Certificate, http2 frees canceled-write memory
By RepoJournal · Filed · About Node.js · Composed from the cited sources · methodology
Node's X.509 series lands its third patch, v8.serialize() gains certificate support with chain handling, and http2 stops leaking memory credit when uploads are canceled.
v8: support X509Certificate serialization nodejs/node
v8.serialize() used to reject X509Certificate objects outright; it now encodes a host object carrying the certificate's DER snapshot, follows issuerCertificate up the chain, and reconstructs fresh instances in v8.deserialize(). The patch reads the stored snapshot rather than the cached raw Buffer, which callers can mutate, and decodes each certificate independently instead of imposing issuer re...
http2: release memory credit for canceled writes nodejs/node
Bytes from a canceled HTTP/2 upload were discarded but still counted against the session's memory limit, which could make later requests on the same session fail with NGHTTP2_ENHANCE_YOUR_CALM. Cleanup now subtracts those bytes before the write callbacks run, with tests covering both server-side cancellation and destroy() from a write callback.
lib: place `value` before `done` in iterator results nodejs/node
Iterator result objects now place value before done, matching what ECMA-262 requires and the order V8 optimizes for. The change buys real throughput: the url/url-searchparams-iterator-consumers.js benchmark with method='Map' measured +35.6% ops/sec. Note the reversal from the lint rule that enforced the opposite order.
deps: load amaro from dist/internal.js nodejs/node
amaro 1.3.0 reduced dist/index.js to a thin wrapper around dist/internal.js, so the built-in now registers and requires internal.js, which would otherwise fail to resolve its sibling. Relevant if you vendor or pin amaro yourself.
feat: index riscv64-pointer-compression builds (#257) nodejs/unofficial-builds
The unofficial-builds index now covers riscv64 pointer-compression builds, which requires a later nodejs-dist-indexer than the one currently in use. The same repo stops building musl x64 after Node.js 26 and had its README run through markdownlint-cli2 --fix.
