'ww test' gains the istest build path (-T injection in build_one/
buildone) and do_test/dotest accept -I, mirroring do_run - both twins.
The 35 converted lib tests drop their interim bare mains (-T
synthesizes the entry from @test fns and rejects a user main); their
35 C run-drivers flip 'ww run' -> 'ww test'; 989_lib_byteid compiles
lib tests under -T (8 user-main probe fixtures stay non-T, gated on
the fixture field). Abort-on-first-failure stands until the deferred
record-and-continue harness lands with the multi-package arc.
package L + import P.L is self-import in Go terms regardless of path
spelling (the parser drops the dotted prefix); the text-level
import-string!=package-name comparison hid these 3 from the PREP-a set.
All three verified black-box (qualifier-only exported-API use) — plain
rename, dotted imports kept as legit cross-package.
The flat checker scope makes ANY decl named assert/abort anywhere in
the combined unit disable the builtin unit-wide (the #45 shadow shape:
scope_lookup_prefer's cross-module fallback finds it). lib carried
three colliding @symbol("rt_abort") shims (os, time, strconv/stof)
plus the os.assert wrapper, so a bare assert(cond) in ANY program
importing os mis-bound os.assert and failed arity — a hard blocker for
regex fold-5 (regex.ha:660/670 bring builtin-assert mass). Ruled
respell-now per the recurrence test (#45 -> #58).
Delete the shims and the os.assert wrapper; every bare abort(msg)
caller (regex, strings, utf8, hash, getopt, encoding/*, time, stof)
now lands on the builtin, and the ~40 os.assert(c, m) sites respell to
the builtin assert(c, m) — restoring the exact Hare spelling the lib
ports diverged from (e.g. ref/hare/bytes/tokenize.ha:23). os.assert
had no Hare counterpart (Hare's assert is a language builtin); rule-9
wrapper removed. temp/dirs/bufio already use the non-colliding rtabort
spelling and keep it.
Now-dead 'import os;' lines kept (pre-existing precedent:
lib/strconv/strconv.ww carries one); a tree-wide dead-import sweep is
a separate concern. regex.ww's if+abort workarounds citing #58 stay
for the fold-5 owner to fold back into assert.
combined.ww regenerated for all five selfhost tools + the smoke
fixture via make.
The literal array dimensions ([64]u8/[8]u32/[64]u32) where Hare uses the
BLOCKSZ def / [_]u32 are forced by ww rejecting a def in array-dimension
position. rule-7 requires a retained divergence carry a filed-task
pointer; add the #269 cite to the header divergence list and the state.x
at-site note (previously described the limitation but cited no task).
Port of ref/hare/crypto/sha256/sha256.ha — block-processed [64]u8
chunks, u32 modular arithmetic, hash::hash + io.writer surface. The
state embeds hash.hash (inline vtable at offset 0); the vtable + sum/
reset slots are wired post-construction (base64/memio convention).
u32 WRAPPING + vtable dispatch CONFIRMED CLEAN: all NIST vectors verify
byte-identical — empty, "abc", the 56-byte block-boundary case, and the
one-million-'a' multi-block stream (1000-byte chunks across many blocks,
stressing write()'s partial-block carry). cgen truncates u32 add/shift/
rotate to 32 bits correctly; no masking workaround needed.
Semantics-preserving spelling divergences (slice-copy as byte loops,
close()/digest loops) are noted at-site per CLAUDE.md rule 5/13.
ONE BEHAVIORAL DIVERGENCE, blocked on a cgen bug (flagged for ken/drew):
Hare's sum() snapshots the state (`let copy = *h`) so it is re-entrant.
That deref-copy of an array-containing struct miscompiles in ww cgen
(copied array fields come back zeroed). So sum() runs on the live state
and is SINGLE-SHOT until the cgen fix lands; every current caller does
one terminal sum(), so the digests are unaffected. Minimal repro:
type t = struct { h: [4]u32 };
let c: t = *(&s); // c.h reads back wrong
A sibling bug (array return-by-value zeroes the result) was also found
and is avoided in the test's buffer-based helper. Both filed for ken.
The hash/crypto modules are dead-imported (no selfhost combined.ww
regen). 9xx test numbers are full, so the run-test shares the 989
prefix with siphash (distinct `short` name; 949_* multi-file precedent).
Subset port of ref/hare/crypto/math/bits.ha: the 32-bit rotations
sha256's message schedule and compression need. The wider bits.ha
surface (rotl64/rotr64, the constant-time compare family, xor) lands as
callers arrive. rotr32 is exercised end-to-end by the sha256 NIST
digest vectors, so no standalone @test ships here.
