jolt build -m ns on a namespace with only top-level side effects and no
-main produced a binary that printed its output, then crashed calling a nil
-main ("nil cannot be cast to IFn"). The launcher now calls -main only when
the entry ns actually defines one; otherwise the top-level forms (already run
at heap build) are the whole program and it exits cleanly. Regression case
added to build-smoke.sh.
Bring the language up to the 1.13.0-alpha1 changes that apply off the JVM:
- req! (CLJ-2949): a get-variant that throws "Expected key: k" on a missing
key, without nil-punning. The primitive behind checked destructuring.
- Checked-keys destructuring (CLJ-2961): :keys!/:syms!/:strs! bind and throw
when a key is absent; keys after & are declared-only (required for the !
variants, accepted otherwise) and create no binding.
- & is no longer a legal local binding in let/loop (CLJ-2954).
- Keyword-only array maps grow to 64 entries before going hash (was 8),
across the literal, assoc, and transient paths, so the common keyword map
keeps insertion order up to 64.
Skipped CLJ-2891 (JVM __init bytecode, JVM-only). 1.13 is still alpha, so
this tracks alpha1 and may shift. Regression tests in test/chez/unit.edn
(ahead of the JVM 1.12.5 the corpus certifies against). Seed re-minted.
jolt is Clojure, so a dep on org.clojure/clojure is always satisfied
intrinsically — the "skipping unsupported coordinate" warning on its
:mvn/version coordinate was just noise. Other unsupported mvn coords
still warn.
The nREPL server bound its loopback socket through libc process symbols,
which don't carry the socket entry points on Windows — they live in
ws2_32.dll and aren't in joltc.exe's export table, so --nrepl-server died
with "no entry for socket". Load ws2_32 before the foreign bindings there,
call WSAStartup once, and use Winsock's closesocket and int-typed
recv/send. Also fix SOL_SOCKET/SO_REUSEADDR, which the old macos-only
check got wrong on Windows.
Bake a version string into the self-contained binary at build time (from
$JOLT_VERSION, else git describe) and expose it via jolt.host/jolt-version:
--version / -V print it, and it shows in --help, the repl banner, and the
nREPL startup line. Dev runs off bin/joltc read it from git describe.
Add -e to the help output.
A user downloaded the auto-generated 'Source code' zip from the release
(no submodules) and hit the raw 'load failed for vendor/irregex/irregex.scm'.
cli.ss and make now check for vendor/irregex up front and print the fix
(clone --recurse-submodules / git submodule update --init --recursive);
README documents both and warns that GitHub's source archives can't build.
Release notes updated with the same pointer.
The -e path worked but jolt build died: jolt_petite_boot_len wasn't
foreign-entry-visible. -rdynamic's Windows equivalent for an exe is an
export table; -Wl,--export-all-symbols provides one.
A literal (foreign-procedure "chmod" ...) in compiled code becomes a fasl
relocation resolved when the boot loads — on Windows (no chmod/sigemptyset/
sigaddset in the CRT) that killed joltc.exe before any guard could run
(msvcrt abort, exit 3). jolt-foreign-proc-safe defers the lookup through
eval at evaluation time, where the guard works and a missing entry just
yields the fallback. chmod also skips the /bin/sh fallback on nt (execute
is by extension).
The built joltc.exe exited 3 (msvcrt abort) with no output on the -e smoke.
Link -static so the exe carries no libwinpthread/libgcc/lz4 DLL deps (needed
for distribution regardless), and add an ntldd + direct-run debug step.
Chez's system/process use cmd.exe on nt; every build command here is
written for sh. bld-sh-wrap spills the command to a temp script and runs
sh on it (no cmd quoting), identity on other platforms.
zuo's install target shells the unix installsh through cmd and dies. The
build tree already has everything: scheme.exe (boot files beside it, where
the Windows kernel looks), and scheme.h/libkernel.a/boots into a csv dir
that JOLT_CHEZ_CSV points the jolt build at.
The Windows PATH step embedded real newlines in its printf strings, which
broke the block scalar and invalidated the whole workflow file (the push
run failed at parse; workflow_dispatch refused). The wrappers are plain
echo pairs now.
rand-nth vec'd its argument, so (rand-nth nil) hit index-out-of-bounds
through the empty vector where the reference's (nth coll (rand-int (count
coll))) returns nil (and a set throws) — the last genuinely-fixable row in
the suite baseline; rand-nth is fully clean now. Corpus/README counts
updated to the current ~3570 rows, the run-corpus regression floor raised
from 2730 to 3390 to match current parity, and the stale traceability line
dropped.
A transient CDN timeout handed bash a 2-minute HTML error page instead of
linux-install.sh and failed the run. curl now fails on HTTP errors and
retries, and the script is sanity-checked before running.
Adds a windows-latest job to the release matrix: MSYS2/MinGW-w64 toolchain,
Chez 10.4.1 built from source (ta6nt), the same build-joltc flow, packaged
as a zip of joltc.exe. The whole job runs in the msys2 shell so cc/xxd/paths
behave; the produced binary is a plain Windows executable.
Platform seams: bld-nt? with the winsock/COM/registry link set, no -rdynamic
under MinGW, GetModuleFileName as the launcher's self-path on _WIN32, and
built binaries (joltc itself and jolt-build outputs) normalize to a .exe
suffix. workflow_dispatch added so the matrix can be dry-run without tagging;
the release upload step only fires on tags.
For #205.
Dialects without JVM interop can now filter the conformance corpus: :jvm
marks rows exercising host interop (java.*/clojure.lang.* class references,
dot forms, ctors, statics, arrays, proxy/bean), :common is portable Clojure
any dialect must satisfy. 3565 rows tagged (3175 common / 390 jvm), the key
documented in the row schema, and regen-corpus preserves it on rewrite.
Closes#289.
Auditing the remaining cts baseline for R7 exposed real contract gaps hiding
among the model residue — all fixed to reference behavior:
- stale no-ratio-era stubs: numerator/denominator now work over jolt's exact
rationals (non-ratio is the Ratio cast failure); rational? includes decimals
- casts and pending: peek/pop demand an IPersistentStack (pop nil is nil),
realized? demands an IPending (a plain list/range throws), transient demands
an editable COLLECTION (non-colls throw; the RFC 0003 sorted/list/seq
superset keeps the copy-on-write fallback), empty on a plain record throws
- nil and empties: (nth nil i) is nil, (nth nil i d) is d, a nil index is NPE,
keys/vals of anything empty are nil, (conj nil) is nil
- lookups: contains? on a string is index-only (other keys IAE), get on an
array is lenient (nth still throws), a VECTOR invocation has nth semantics
(([1 2] 5) throws — call position and jolt-invoke both)
- into only transients editable collections; a PersistentQueue/sorted target
folds through conj (RT's IEditableCollection split)
- numbers: number?/num accept BigDecimal, quot/rem throw on an Infinite/NaN
quotient, even?/odd? demand integers
- ordering: keywords compare namespace-first with nil first (Symbol.compareTo)
- misc: run! honors reduced, eval self-evaluates non-form values, intern
demands an existing namespace, counted? excludes strings, seqable? includes
arrays, shuffle rejects maps, sort-by rejects a collection comparator,
when-let demands one binding pair, case*/deftype*/letfn*/reify*/& are
special symbols
Two mis-certified corpus rows fixed (they threw on the JVM too and hid in the
tolerated bucket): a raw \d string escape and duplicate literal map keys.
SPEC.md gains the baseline-traceability section: every one of the 146
remaining suite failures maps to a documented divergence (integer-box,
no-single-float, RFC 0003 transients, seq/chunking model, stm-refs,
parse-uuid strictness, vec-array adoption). cts baseline 5955 -> 6042 pass,
5 errors, 30 namespaces. 9 JVM-certified corpus rows.
The reader now rejects what the JVM reader rejects: a token that starts
like a number but doesn't parse is NumberFormatException (1a, 08, 0x2g,
2r2 — never a symbol); ratio parts are digit runs (1/-1 invalid) with a
zero denominator throwing ArithmeticException; empty ns/name parts are
invalid tokens (:, ::, foo/, /foo) while /, ns//, and :/ stay valid;
duplicate map keys and set elements throw at read; unsupported string
escapes and octal escapes past \377 throw; a stray close delimiter is
'Unmatched delimiter'; \r ends line comments. #inst validates its
calendar fields progressively (leap years included) and #uuid demands
canonical hex. 1-arg symbol splits its ns at the FIRST slash
(Symbol.intern): (symbol "foo/bar/baz") is foo/"bar/baz".
clojure.edn gets its own strict seam (__read-form-edn): auto-resolved
keywords are invalid there, every #_ discarded form validates through the
same :readers/:default pipeline (an unreadable tagged element throws even
when discarded), built-in tags win over :default, M literals construct
BigDecimals, lists satisfy list?, and EOF honors :eof — an opts map
without :eof makes end-of-input an error.
clojure.edn-test.read-string goes 246 pass / 46 fail / 5 errors -> 297/0/0
(fully clean). cts baseline 5904 -> 5955 pass, 23 errors, 56 baselined
namespaces. 9 JVM-certified corpus rows; reader spec section.
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.
byte/short/int/long/char silently wrapped or passed out-of-range values
through; the JVM range-checks (RT.byteCast family). One checked-cast
helper now carries the ranges: a double range-checks ITSELF before
truncating ((byte 1.1) is 1, (byte 127.000001) throws), NaN casts to 0,
ratios and bigdecs truncate, a non-number is CCE, and the throw carries
the JVM message. float range-checks against Float/MAX_VALUE. The
unchecked-* casts now genuinely wrap and sign-fold ((unchecked-byte 200)
is -56 — the old bit-and lost the sign) with doubles saturating like
Java's conversions; unchecked-long/int are host natives. double/float of
a bigdec convert instead of crashing. The no-single-float residue stays
accepted (SPEC.md).
Also fixes#290: a binary built by the SELF-CONTAINED joltc died with
'variable var-deref is not bound' when a namespace loaded at runtime.
The in-process build compiled flat.ss against a clean copy-environment,
which orphans every top-level define in locations the binary's runtime
eval can't see. It now compiles against the default interaction
environment (defines land in the real symbol cells, same as the legacy
fresh-Chez path) and a generated prologue pre-binds each kernel name the
runtime redefines to its kernel value, so the earliest boot reads match
the legacy path's primitive references. requiring-resolve is implemented
(the issue's dynamic-require pattern), and the release workflow smokes a
runtime require in a built binary.
Cast namespaces byte/short/int/long/char now fully clean; cts baseline
5805 -> 5857 pass, 67 baselined namespaces. 7 JVM-certified corpus rows.
add-watch/remove-watch/set-validator!/get-validator were atom-only; the
atom ctor ignored :meta and :validator; watching a var crashed. Now the
ARef contract is one seam: atoms keep their record slots (hot path
unchanged), every other reference type registers a predicate and stores
watches/validators in identity-keyed side tables, and notifies at its
mutation points. Vars notify on root changes (def on a watched var,
var-set outside a thread binding, alter-var-root — thread-binding sets
don't notify, like the JVM); agents notify per action. The def-var! wrap
costs two weak-table probes per def and does IRef work only on a watched
var.
Ctor options follow ARef: the validator gates the initial value
(IllegalStateException 'Invalid reference state' — also the class for
rejected swap!/reset!), :meta must be a map (else ClassCastException),
nil allowed. meta reads any reference through the identity side-table
(the type-gated fall-through is gone); alter-meta!/reset-meta! work on
non-var references.
Runtime-only (no re-mint). 9 JVM-certified corpus rows; spec entry; cts
baseline 5781 -> 5805 pass, 73 baselined namespaces (the residual error
in the watch namespaces is their STM ref section — refs stay out of
scope).
derive/underive/ancestors/descendants/parents/isa? re-ported from
clojure.core with the argument assertions and throw contracts intact:
derive asserts tag/parent shapes (AssertionError) and throws on redundant
or cyclic derivation; underive/derive on a non-hierarchy value throw at the
parents lookup (the map is called as a function, like the reference);
(descendants h SomeClass) throws UnsupportedOperationException. isa? gains
the reference's supers arm (a relationship derived on a class's super
applies to the class).
The class arms now answer fully through the one class graph: parents of a
class are its direct supers (bases), ancestors are the transitive set
rooted at java.lang.Object for concrete classes (interfaces are marked and
don't root at Object, matching getSuperclass semantics). deftype/defrecord
classes register into the graph at definition — protocol interfaces they
implement appear as supers (JVM-munged ns spelling), records carry the
record interfaces (IRecord/IPersistentMap/... whose closure supplies
Associative/Seqable), bare deftypes carry IType. The type NAME var still
holds the ctor (a jolt-ism); class-key maps it back to the class so
(ancestors TypeName)/(isa? x TypeName) work. canonical-host-tag learned to
NOT canonicalize deftype names through the graph arm (extend-type on a
deftype was registering under the bare segment its values never report).
Five old corpus rows used non-namespaced derive tags that throw on the JVM
too; now namespaced. 8 new JVM-certified corpus rows; spec entries for the
hierarchy family; cts baseline 5730 -> 5781 pass (ancestors/derive/
descendants/parents/underive namespaces fully clean), 74 baselined
namespaces.
Arithmetic and comparisons lowered to raw Chez ops, so an operand outside
Chez's tower (BigDecimal) crashed with a raw condition, and Chez contagion
leaked: (* 1.0 0) gave exact 0 where the JVM gives 0.0, (* ##Inf 0) gave 0
instead of ##NaN, (/ 1 0) raised an untyped error.
One seam now (host/chez/seq.ss): call position emits jolt-n* macros with the
both-Chez-numbers fast path open-coded; value position folds through the same
binary ops. Anything outside the tower falls to per-op slow hooks that
java/bigdec.ss extends, so bigdec arithmetic works in every position (the old
static-only :bigdec typing limitation is gone). JVM rules patched into the
fast path: a double operand wins, an exact zero divisor throws
ArithmeticException while a double zero divisor yields Inf/NaN, quot/rem/mod
cover ratios and doubles, min/max return the original operand with NaN
winning, a nil operand is NPE and a non-number CCE, zero-arg -// throw
ArityException at runtime instead of failing expansion.
Also: with-precision now binds *math-context* and bigdec results round with
real RoundingMode semantics (UNNECESSARY throws; division rounds to precision
instead of throwing); rationalize goes through the shortest decimal print
like BigDecimal.valueOf (the identity stub is gone); ratios coerce to bigdec
like Numbers.toBigDecimal; min/max int-literal operands no longer coerce to
flonum in the numeric pass.
Perf neutral: fib and seq benches unchanged (the fast path is two type checks
the optimizer folds); hinted fl/fx paths untouched. 19 JVM-certified corpus
rows; cts baseline 5614->5730 pass, 192->88 errors, 84->79 baselined
namespaces.
are let-bound its template vars, so a var inside quote never substituted:
(are [x] (special-symbol? 'x) if def) tested the literal symbol x twice.
Rebuild are on clojure.template/do-template (postwalk substitution), the
same architecture as upstream, with the same arg-count check.
This un-aborts every suite namespace whose are rows need substitution:
cts baseline moves 5302->5614 pass, 236->192 errors, 88->84 baselined
namespaces. The newly-reachable assertions also surface real divergences
now baselined and filed (edn reader strictness, Boolean ctor).
jank-lang/clojure-test-suite (per-core-fn clojure.test suites shared across
Clojure dialects) joins the default gate as vendor/clojure-test-suite, run by
host/chez/cts.sh: one joltc process per test namespace (a hang or crash is
contained by a per-process timeout), through the test/chez/cts-app project and
its cts-run runner, parallel workers.
Gating is exact per namespace against test/chez/cts-known-failures.txt, like
certify's allowlist: a namespace doing worse than the baseline fails, and one
doing better also fails as stale until the baseline is updated in the same
change. JOLT_CTS_WRITE_BASELINE=1 regenerates it; JOLT_CTS_NS runs a subset
verbosely.
Current standing: 243 namespaces, 5302 assertions pass, 340 fail + 236 error
across 88 namespaces pinned in the baseline (dominant clusters: BigDecimal
arithmetic operands, derive/ancestors hierarchy, transients, special-symbol?,
clojure.string case fns, the accepted narrow-int and seq-type-model
divergences). Two consecutive full runs produce identical counts. Wired into
make ci; skips cleanly when the submodule isn't checked out.
Five fixes shaken out by running jank-lang/clojure-test-suite:
- = short-circuits on identity like Util.equiv's k1 == k2, so (= s s) on an
infinite lazy seq answers true instead of walking forever. Numbers keep the
exactness-aware arm ((= ##NaN ##NaN) stays false like the JVM's).
- Calling a non-fn names the operator's CLASS in the ClassCastException, like
the JVM — never the value, whose printed form may be unbounded: ((range))
must throw, not hang rendering an infinite seq.
- realized? on a seq cell answers by its forced flag (the rest of a realized
lazy chain is a cseq under jolt's seq model), and the overlay's unsupported-
type error names the class, not the (possibly infinite) value.
- clojure.test/is dispatches a REGISTERED assert-expr method before its by-name
inline paths, like clojure.test where the built-ins are just pre-registered
methods — so an alias-qualified p/thrown? (the suite's portability helper)
isn't captured by the built-in thrown? path, which read its body as a class.
- clojure.test tracks tests and fixtures per namespace: deftest records its
defining ns, use-fixtures registers under the calling ns (no more cross-ns
clobbering), (run-tests 'ns ...) runs only those namespaces like clojure.test,
and each run-tests call prints/returns its own summary (global counters stay
cumulative for the n-pass/n-fail harness API).
Re-mint (20-coll.clj is seed; prelude only). +2 JVM-certified corpus rows;
the clojure-test fixture pins the alias-qualified assert-expr, per-call
summaries, and ns filtering.
The macos-13 Intel runner no longer gets allocated, so the x86_64-macos release
job queues forever. Ship prebuilt binaries for x86_64-linux and aarch64-macos;
Intel Macs build from source. The install script now says so instead of 404ing
on a missing asset.
next.jdbc's own source needs clojure.datafy + clojure.java.data and its tests
need JVM JDBC drivers, so it doesn't run on jolt. Keep clojure.jdbc (via
jolt-lang/db's jdbc.core over FFI SQLite) as the supported JDBC surface; point
migratus at jolt-lang/db.
The self-contained build reads the bundled Chez petite/scheme boots from the
joltc binary via foreign-entry on the embedded jolt_* symbols. On Linux dlsym
can't see an executable's symbols unless they're in the dynamic symbol table, so
'build' died with 'foreign-entry: no entry for jolt_petite_boot_len'. -rdynamic
exports them (macOS already resolves them). The new release self-contained-build
smoke caught this on the Linux runner.
`joltc build` inlines the runtime (host/chez/rt.ss and everything it loads, the
seed, compile-eval, loader, ffi, the vendored irregex) into each app binary by
reading those files off disk. That works from a jolt checkout but not from the
installed self-contained binary, which has no source tree:
joltc build -m app.core
=> Exception in call-with-input-file: failed for host/chez/rt.ss: no such file
build-joltc now bakes the exact transitive closure of files the build inlines
into the binary as embedded resources (keyed by the path the `(load "…")` forms
use), and build.ss/dce.ss read runtime source through bld-source-string, which
takes the embedded copy when present and falls back to disk otherwise. So the
same joltc builds apps both from a checkout and standalone.
The release workflow now smoke-tests a self-contained build (compile a tiny app
from an isolated dir, run it) — this is exactly what shipped broken, so it now
gates the release. buildsmoke/shakesmoke/staticnativesmoke unchanged and green.
Build tooling only — no re-mint, no runtime change.
install (root) downloads the self-contained joltc release asset for the host
platform, verifies its sha256, and drops the binary in /usr/local/bin (--dir /
--version override). Resolves the latest release via the GitHub API, clears the
macOS quarantine flag, and backs up an existing joltc. Modeled on babashka's
installer. README gets a one-line curl|bash install.
Document the register-class-supers! seam next to the other host-class hooks:
when a library class belongs to a hierarchy (a custom exception caught as
IOException, a value matching instance? across its supertypes and dispatching a
protocol extended to any of them), declare its supers once and instance?/isa?/
supers/extend-protocol all derive.
