jolt's `is` was a fixed macro with no assert-expr multimethod, and the runner
bypassed the report multimethod, so libraries couldn't register custom
assertions or custom report types (e.g. test.check's ::trial/::shrunk).
Add assert-expr (2-arg [msg form], dispatch on the form's first symbol /
:default / :always-fail), do-report routing through report, and report
:pass/:fail/:error methods that feed the counters. `is` dispatches to an
explicitly-registered assert-expr method before its inline path, so thrown?/
thrown-with-msg?/= and every built-in form stay byte-identical.
Runtime stdlib only, no re-mint. test/chez/clojure-test.clj self-checks the
extension points + full is/are/testing/thrown?/use-fixtures surface; smoke gate
runs it.
- (proxy [ThreadLocal] [] (initialValue [] body)) now builds a real per-thread
store backed by a Chez thread-parameter, with a lazy initialValue; .get/.set/
.remove work. Other proxies stay nil. test.check's no-seed PRNG (next-rng) uses
one, so gen/sample and gen/generate (and everything built on them) now work.
- clojure.test/*testing-vars* (+ *report-counters*) are bound vars now, so a
defspec run through its :test metadata / default reporter doesn't hit an unbound
var.
make test green (+1 corpus row), shakesmoke byte-identical. One re-mint (proxy).
Running clojure.tools.reader's own suite on jolt surfaced a batch of general
gaps (all runtime, JVM-certified, no re-mint — reader.ss is loaded at runtime
and jolt-core has no octal literals, so selfhost holds):
Reader:
- (load "rel") resolves a non-/ path against the current namespace's directory,
like Clojure — (load "common_tests") from clojure.tools.reader-test loads
clojure/tools/common_tests.clj. Was resolved against the roots directly.
- Octal integer literals: 042 reads as 34, not decimal 42; octal string escapes
(\377 is one char, not \0 + "00"). \oNNN char octal already worked.
- (symbol nil name) now equals (symbol name) and the reader literal — a nil
namespace is the #f no-ns sentinel, not jolt-nil (jolt= compares ns by equal?).
clojure.test:
- thrown-with-msg? honors the class hierarchy (instance?) before falling back to
a simple-name match, so (thrown-with-msg? RuntimeException ...) matches an
ExceptionInfo, like thrown? already did.
Host interop (java layer):
- java.util.regex: Pattern.matcher / Matcher.matches / .group / .groupCount /
.find, and Pattern/compile.
- clojure.lang: RT/map, PersistentList/create, PersistentHashSet/createWithCheck.
- java.lang.Character: digit / isDigit / isWhitespace / valueOf.
- java.util.LinkedList (Deque surface over the ArrayList backing); ArrayList /
LinkedList are now seqable.
- BigInteger 2-arg ctor (string, radix) + .negate / .bitLength / .signum / .abs;
BigInt/fromBigInteger and Numbers/reduceBigInt (identity on jolt's exact ints).
Suite: reader_test 22/30, reader-edn_test 13/16. The remaining failures are
fundamental numeric-model differences (no BigDecimal type; BigInt and Long are
one exact-integer type) or need JVM reflection (record/ctor tagged literals via
getConstructors) — out of scope.
make test green (+8 corpus rows, 0 new divergences), shakesmoke byte-identical.
Six correctness fixes, each a general gap (not hiccup-specific):
- deftype is not a map. jolt treated every deftype instance as a map
(map?/record?/seqable over its fields); in Clojure only a defrecord is
map-like, a bare deftype is an opaque object. defrecord now marks its type;
map?/record?/coll?/seq/empty? gate on it, while a deftype implementing a
collection interface still dispatches through its methods.
- cross-ns extend-protocol on an imported deftype. register-method built the
type tag from the *calling* ns + bare name, so (extend-protocol P Raw …) in
one ns missed a Raw value defined in another. A simple-name index resolves
the bare name to the type's real tag (local ns still wins).
- str vs print. str of a collection is its readable form (nested strings
quoted: (str ["x"]) => ["x"]); print leaves them raw. jolt defined print
as str, conflating the two. Split via a __print1 seam.
- clojure.test thrown? now honors the exception hierarchy (instance?), so
(thrown? IllegalArgumentException …) matches an ArityException subclass.
- java.net.URI is value-equal (= and hash by string form).
- clojure.walk/macroexpand-all was missing; an unresolved qualified var made
the analyzer report "Unknown class walk".
deftype/defrecord + print are seed sources, re-minted. hiccup 365->381 of its
own suite; the rest are charset-encoding / var-meta niches.
class / .getClass now return a Class value that renders like the JVM —
(str c)/.toString -> "class <name>", pr -> "<name>", .getName/.getSimpleName/
.getCanonicalName work — but stays = and hash equal to its name string, so
(= (class x) String), class-keyed maps, multimethod dispatch on class, and
instance? keep working against the bare class-name tokens. instance? unwraps
a Class passed as the type arg.
clojure.test/class-match? no longer assumes (class e) is a string (a jolt-ism;
on the JVM a Class isn't a string either) — reads the name via .getName.
Matches JVM Class.toString, which libraries surface in error messages
(clojure.data.json DJSON-54 expects "...of class java.net.URI"). data.json
suite 139/139 bar the one UTF-16 surrogate test (Unicode-scalar char model).
5 corpus rows certified vs JVM; make test + shakesmoke green, 0 new divergences.
clojure.test reported a host-condition crash with a blank message (ex-message is
nil for non-ex-info conditions); fall back to jolt.host/condition-message.
condition-message itself left a Chez format-template message (open-input-file's
'failed for ~a: ~(~a~)') unformatted; apply its irritants.
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.
