SQLite lands, HTTP and parser fixes follow

node:sqlite is now fully implemented (8df2aa5)

Bun adds the node:sqlite module and wires it into the build, shutdown path, and compat docs. The implementation brings the Node v26.3.0 test suite along with native backup/session-related APIs and macOS runtime gating, making SQLite a first-class Node compatibility surface.

Postgres row parsing now rejects malformed message overruns (6352b79)

DataRow, RowDescription, and ParameterDescription decoding now bounds every read by the enclosing message length instead of treating overruns as a recoverable short read. This closes a protocol bug that could stall queries indefinitely or misparse later wire bytes.

HTTP and S3 close-delimited responses keep their metadata intact (3655b03, 8adb8de)

The HTTP client now treats close-delimited responses more carefully, avoiding progress callbacks that expose partial bodies before terminal metadata arrives. The S3 response path also preserves response headers across later EOF callbacks, fixing a crashy class of responses without Content-Length or Transfer-Encoding.

HTTP/1.0 no longer gets broken chunked responses (9d9fe3b)

When Content-Length is removed, Bun now falls back to close-delimited responses for HTTP/1.0 clients instead of advertising chunked encoding it cannot actually frame. That fixes a real interoperability bug with proxies like nginx.

node:test gets real mock access on TestContext (1b2bb4e)

The test runner’s TestContext.mock now returns the shared mock tracker instead of throwing, unlocking more upstream Node test coverage. This is part of the larger push to match Node’s in-process test API.
