* test: Ensure failure to throw at all doesn’t pass (brianc#3671) * Assorted test fixes and cleanup (brianc#3672) * cleanup: Remove duplicate test * cleanup: Remove nonsense test * cleanup: Simplify promise rejection test * test: Fix and tighten assertion that would always pass because of the `SELECTR` typo. * cleanup: Add missing `await`s when using `assert.rejects` in tests; remove unneeded function wrappers * ci: Node 26 followup (brianc#3670) * Revert unneeded pg-native→libpq dependency range adjustment This reverts part of commit 1025d12. * dev: Upgrade libpq/nan in lockfile for Node 26 compatibility * fix: apply SASLprep (RFC 4013) to passwords before SCRAM-SHA-256 PBKDF2 (brianc#3669) * fix: apply SASLprep (RFC 4013) to passwords before SCRAM-SHA-256 PBKDF2 `pg`'s SCRAM-SHA-256 client passes the raw password into PBKDF2 with no normalization, while PostgreSQL's server (and libpq) apply SASLprep (B.1 mapping -> NFKC -> prohibition + bidi check) when computing the stored verifier. Passwords whose NFKC form differs from themselves (e.g. containing U+00A8 dieresis, U+2011 non-breaking hyphen, U+00BC vulgar one quarter, NBSP, soft hyphen) authenticate with psql/libpq but fail against pg with `28P01`. Wire `@mongodb-js/saslprep` (the maintained fork used by mongodb's official Node driver) into `continueSession` before `crypto.deriveKey`, with a try/catch fallback to the raw password on prohibited / bidi violations to match `libpq`'s `pg_saslprep` behavior. Also adds: - Unit tests covering the soft-hyphen B.1 mapping equivalence, the Roman-numeral-IX NFKC asymmetry, the prohibited-char fallback, and a deterministic snapshot for the original bug-report password. - A gated integration test block (SCRAM_TEST_PGUSER_UNICODE / SCRAM_TEST_PGPASSWORD_UNICODE) covering raw + NFKC-equivalent + wrong password. - A `scram_unicode_test` role (password `U&'IX-\2168'`) provisioned in CI plus matching env vars so the new integration tests run on every Node version. - A Cloudflare Workers regression guard that exercises `sasl.continueSession` to ensure `@mongodb-js/saslprep` resolves cleanly under workerd. - A `pg@8.21.0` CHANGELOG entry. * fix: inline SASLprep, drop @mongodb-js/saslprep dependency Per review feedback on brianc#3669: ship the SASLprep step as a small in-tree function instead of pulling a runtime dep with an unpinned transitive. The function performs only the three byte-changing steps from RFC 4013 (Table C.1.2 -> SPACE, Table B.1 -> empty, NFKC) and skips the prohibition (RFC 4013 section 2.3) and bidi (RFC 3454 section 6) checks, since libpq is forgiving on those paths and Postgres's own SASLprep is similarly lenient. Removes the try/catch fallback (no code path throws). The deterministic snapshot tests stay byte-for-byte valid because none of them touch U+200B, the only edge case where the inline impl diverges from `@mongodb-js/saslprep`. RFC 3454 places U+200B in Table B.1 (mapped to nothing); the dep maps it to SPACE. PostgreSQL's saslprep.c follows the RFC, so the inline impl matches libpq more closely on that codepoint. The B.1 unit-test rename ("passes ASCII control characters through normalization unchanged") keeps the same snapshot bytes since BEL is unchanged by all three steps.

RFC 4013 SASLprep is probably misusing that list of non-ASCII spaces, and says nothing about the overlap. (At least it’s obsoleted.) * cleanup: Simplify regex character classes with ranges --------- Co-authored-by: charmander <charmander@noreply.github.com> Co-authored-by: Charmander <~@charmander.me> --------- Co-authored-by: Charmander <~@charmander.me> Co-authored-by: charmander <charmander@noreply.github.com>
