SEA gets ZIP asset archives, HTTP server sheds per-request allocations
By RepoJournal · Filed · About Node.js · Composed from the cited sources · methodology
Node.js landed two runtime-facing changes: a "vfsArchive" option that serves SEA assets straight from a prebuilt ZIP, and an HTTP server pass that removes the closures and header lookups paid on every request.
sea: add vfsArchive to serve the assets from a ZIP archive nodejs/node
Matteo Collina added a "vfsArchive" option to the SEA configuration, letting --build-sea embed a prebuilt ZIP verbatim as a single reserved asset instead of listing individual "assets" entries; the same work fixed a performance bug in the SEA asset lookup found while benchmarking it.
http: reduce per-request allocations in the server nodejs/node
updateOutgoingData.bind() is now one closure per connection reused by every response, resOnFinish.bind() became a shared 'finish' listener that reaches state through the connection stored on the response, and the Host, Expect, Content-Length and Transfer-Encoding header checks can skip materializing req.headers. Every Node HTTP server pays these costs once per request today, so the win scales w...
tls: preserve CN name constraints with OpenSSL 4.1 nodejs/node
OpenSSL 4.1 stopped applying DNS name constraints to the subject CN by default, while tls.checkServerIdentity() still consults it when no DNS SAN is present, so the patch enables subject name constraints to preserve the existing behavior. Relevant if you build against or test against OpenSSL 4.1.
doc: document the node:ffi call paths nodejs/node
doc/api/ffi.md now documents all three node:ffi call paths, the V8 Fast API with a generated trampoline, the per-function shared buffer path that was previously undocumented, and the generic libffi invoker, plus the order in which one is selected and which signatures qualify.
adds beta docs to learn nodejs/learn
Beta docs now appear in learn, reordered after the current docs, with a ui-components bump to fix the nav accent and lint left off for the moment. The doc-kit packages moved from 1.4.3 to 2.0.2 in the same stretch of dependabot work.
