The clojure.string case fns and searches now take any Object s through its
toString like the reference's ^CharSequence signatures ((upper-case :kw) is
":KW", (capitalize 1) is "1"); nil throws, and a nil substr in
starts-with?/ends-with? throws. some-fn re-ported with the reference
arities: (some-fn) is an arity error and a no-match result is the last
predicate's own falsy value (false, not nil). ifn? covers multimethods,
promises (which are now invocable — calling one delivers, via a cold-path
invoke-arm registry that costs the hot dispatch nothing), and deftypes
implementing IFn's invoke.
One structural find on the way: defmulti/defmethod deferred inside a fn
body (the deftest pattern) interned/resolved in whatever namespace was
current when they RAN, not the one they were written in — the macros now
bake their expansion ns and the setups honor it.
Also: Boolean/Integer/Double wrapper ctors, primitive TYPE statics
(Integer/TYPE etc.), .reduce on collections (IReduce), and Long/TYPE.
cts baseline 5857 -> 5904 pass, 58 -> 28 errors, 57 baselined namespaces —
the string cluster, some-fn, ifn-qmark, boolean-qmark, and reduce
namespaces are all fully clean. 7 JVM-certified corpus rows; spec entry.
Round 1 (correctness + dead code):
- Fix duplicate java.util.HashMap registration in host-static.ss: the alist
impl shadowed the hashtable ctor while leaving the hashtable methods bound,
so .keySet/.values/.remove/.clear crashed. Drop the alist version.
- Delete jolt-core/jolt/reader.clj: a 463-line dead duplicate reader, never
required or compiled (the live reader is host/chez/reader.ss) and drifted.
- Remove dead defs: ir/rt + :rt op + unused ir/op; the Janet branch in
clojure.edn/drain-reader; a shadowed first clojure.string/trim-newline;
io.ss jolt-char-array + the reader def-var (both shadowed by natives-array);
concurrency.ss jolt-future-done?*; compile-eval.ss jolt-analyze-emit.
Round 2 (perf + determinism):
- emit-quoted-map-value / quoted sets now emit sorted by emitted text instead
of host-hash order, which isn't stable across Chez versions (jolt-8479).
- jolt-into folds through a transient, so into/vec/mapv/filterv onto a vector
are O(n) instead of O(n^2).
- deps resolve-deps walks its queue with an index cursor (was subvec-per-pop).
- async channel and agent action queues use amortized-O(1) FIFOs; ArrayList is
backed by a growable vector (O(1) add/get) instead of a list.
Rename src/jolt -> stdlib (the runtime-loaded layer; jolt-core stays the
seed-baked layer) and update the loader / emit-image / doc paths. Drop dead
code: the spike/ experiments, the duplicate clojuredocs-export.edn (json moves
to tools/), the Janet-era jolt.http binding, and the orphaned
persistent_vector.clj whose ns/path didn't even match.
Strip porting residue from comments and docstrings across host/chez, jolt-core,
stdlib, tests, and docs: internal issue ids, "Phase N" markers, and the "vs
Janet" historical exposition, leaving present-tense descriptions and the real
JVM-Clojure semantic contrasts. Same pass over the corpus suite labels. The seed
is unchanged (docstrings/comments aren't emitted), so the self-host fixpoint and
corpus are untouched.
Port tools/spec_coverage.py off the dead janet probe to bin/joltc and regenerate
coverage.md; drop the dead :host/janet rule from certify.clj and regenerate the
conformance profile. Add docs/host-interop.md (the JVM shims and how to register
your own host class from a library) and a writing-style note in CLAUDE.md.
Stabilize the four racy concurrency corpus cases (future-cancel and agent
send/send-off): give the future a sleeping body and the agent a slow action, so
cancel reliably catches an in-flight future and deref reliably reads the
pre-update snapshot. They certify deterministically now, so drop their :flaky
allowlist entries and the orphaned legend.
