The corpus certifier (test/conformance) flagged four cases where jolt's
hand-written :expected matched a real defect rather than Clojure. Fixed in the
jolt-core overlay, corrected the spec :expected, re-certified against JVM Clojure:
- ex-message: returns nil for a non-throwable (dropped the lenient string branch);
still returns the message for ex-info. (jolt-l8e8)
- munge: preserves the argument's type — a symbol munges to a symbol, not a string.
(jolt-hc35)
- print: (print nil) emits "nil", not "" (top-level nil guard; str yields "").
(jolt-pqio)
- bounded-count: uses the counted? fast path (full count), else counts up to n via
seq — was (min n (count coll)), wrong for counted colls. Added an uncounted-coll
spec case. (jolt-2507)
Removed the 4 :bug entries from known-divergences.edn (now certified), regenerated
corpus + profile, re-minted the Chez bootstrap seed (clojure.core changed). Gates:
Janet 155/0, JVM certify clean, both Chez corpus gates 2534 (floors raised),
bootstrap 6/6, fixpoint intact.
jolt's catch is (catch class binding body*); the binding (3rd element) must be
a symbol. Neither the analyzer nor the interpreter validated it, so a non-symbol
binding crashed with an internal Janet error (expected integer key for array...)
and, in the interpreter, a malformed clause whose body never threw was silently
swallowed (returned the try value). Clojure rejects a non-class/non-symbol catch
clause; match that with an up-front error in analyze-try and eval-try.
Surfaced building the Chez try/throw emit. Regression rows in exceptions-spec
(runs x3 modes) plus a unit test asserting the clean message in interpret and
compile. jolt-kg6p.
adds self-hosted compiler is functionally:
- The default compile path is the portable pipeline using jolt.analyzer (Clojure) → host-neutral IR → backend.janet.
- The analyzer is itself Clojure, compiled by jolt for true self-hosting.
- bootstrap-fixpoint passes (stage1 == stage2 == stage3): rebuilding the compiler on its own output.
- clojure.core is now self-hosted in the overlay.
- Stateful forms (defmacro/ns/deftype/defmulti/require/in-ns) are interpreted by design.
Mine the remaining integration 'ported Clojure' batteries into the spec layer
and delete them (clojure-atom/control/for/logic/macros, core, logic). A broad
function-coverage diff confirmed they exercised no clojure.core fn the spec
lacked; their distinctive value was the truthiness/boolean contract, now
captured in a dedicated spec.
New/expanded spec coverage:
- spec/truthiness-spec: only nil/false are falsy (0, "", [], {}, #{} are truthy);
not / and / or return-value & short-circuit semantics; if-not/when-not/boolean
- assert (exceptions-spec), get-validator (state-spec)
Layout now: spec 23 files / 732 cases; integration trimmed to 10 genuine
cross-cutting batteries (conformance, SCI bootstrap/runtime, jank, compile-mode,
api, namespace, bootstrap, features, systematic-coverage). conformance 218/218,
jpm test green.
Close jolt-dd5.
- catch now binds the originally-thrown value (unwrapping the :jolt/exception
envelope), so (catch ... e (throw e)) rethrows the same exception instead of
nesting another envelope, and (catch ... e e) on (throw 42) yields 42.
- var-set updates the innermost thread-binding frame for the var (replacing the
stack slot) when the var is dynamically bound, matching Clojure; it falls back
to the root otherwise.
Restored spec cases: exceptions rethrow + catch-binds-thrown-value, namespaces
var-set-in-binding. conformance 218/218, jpm test green.
Mine the cljs port batteries into the spec layer and delete them (their behavior
is covered by spec; the unique functions they exercised are now specced).
Removed test/integration/ports/ entirely.
New/expanded spec coverage from the mining:
- spec/exceptions-spec: try/catch/finally, throw, ex-info/ex-message/ex-data/ex-cause
- doto, pr-str, keyword/symbol constructors, atom?, dynamic var binding
Two rare edges filed (jolt-...): rethrow of a caught ex-info re-wraps it; var-set
on a dynamic var inside binding no-ops. Core try/catch/ex-info and binding work.
Test layout is now spec (22 files, ~677 cases) / integration / unit / support.
conformance 218/218, jpm test green.
