Benchmark exercises full save×load matrix across Python/C/asm plus the
mismatch cases (wrong format, truncated input, missing file, corrupt
header). Cases that used to segfault or report wrong paths now degrade
cleanly.
asm (uncommonlisp.s):
- (define var) with no value now binds to VOID instead of segfault
- portal-resume checks sys_read returned full 48-byte header; sanity-
checks heap_size and heap_base before committing r14/r15 restore.
Corrupt/truncated portals now return #f cleanly.
py (uncommonlisp.py):
- file-not-found error inside a nested (load) now reports the actual
missing path (via FileNotFoundError.filename) rather than the outer
script path.
- _load wraps UnicodeDecodeError (binary file loaded as text) into a
LispErr with the path; no more raw Python traceback.
tests/portal-benchmark.sh: 50-iter benchmark, 4 parts
(save / load / cross-process / mismatch-classification).
Representative numbers (this laptop, 2026-04-16):
setup+save: Python 126ms, C 3ms, asm 0.9ms
cross-proc: Py→Py 260ms, C→C 6ms, asm→asm 1.5ms
All three test suites still pass: 571 py unit, 131 asm, 189 shared.
67 new tests covering: any/every/find/count/sort/iota/fold-right,
named let with multi-body, internal defines, letrec mutual recursion,
do loops with results, tail position in cond/when/unless/and/or,
nested closures with mutation, deep TCO at 200k depth, string ops
(contains/split/join/trim), apply, variadic args, quasiquote splicing,
set-car!/set-cdr!, list-tail, make-list, hash-table-delete!.
Both Python and C pass 181/181.
tests/functional.lsp — single .lsp file, runs identically in Python and C.
Covers: arithmetic, comparison, booleans, pairs, lists, strings, characters,
vectors, hash tables, control flow, let/lambda/closures, do loops, define,
recursion, TCO (100k depth), quasiquote, macros, type predicates, call/cc,
error handling, mergesort, higher-order programs.
Fixed C call/cc: proper escape continuations via setjmp/longjmp.
make test-all runs: Python unit (571) + C unit (58) + shared functional (114).
