The binary was stamped before dev advanced (vindex publication landed in
el_runtime.c and engram_vindex.c). Rebuilt against the merged runtime so the
committed compiler matches the runtime it ships beside. Fixpoint re-verified
byte-identical; test_compiler 82/82; engram/src/server.el still compiles and
still emits its 18 config declarations.
server.el declares a `program` block, which the previously committed elc cannot
parse. Without this the tree is internally inconsistent: source in the repo that
the compiler in the repo rejects.
This is the documented re-stamp from BOOTSTRAP.md / AGENTS.md, and its
precondition is met -- the self-hosting fixpoint was verified byte-identical
(stage3 output == stage2 output) both before installing and again with the
installed binary. tests/native/test_compiler.el passes 82/82 against it.
Two pre-existing failures are unchanged and are NOT from this work, confirmed
by rebuilding them against the original runtime: test_env's
"state_keys returns JSON array" fails identically before and after, and
test_json/test_state fail to link on symbols (json_build_array, state_has) that
were never prototyped -- the same class of gap as config(), which this branch
fixed because it blocked the build.
Float + previously fell through to string concat (segfault); -, *, /, %
operated on raw IEEE-754 bit patterns as integers (garbage results). Floats
are now tracked via a __float_names typed-binding set (parallel to the
existing int-tracking scheme) and arithmetic is emitted as real C double
ops.
Also fixes math_log, which was wrongly aliased to natural log (duplicating
math_ln) — now uses log10 — and adds the missing <math.h> include. Rebuilt
elc binary included.
Rebuilt from fix/elc-oom-checkout: scan_fn_sigs_el() --emit-header path
+ el_mem_check() guard. Verified on checkout.el: all 3 sigs in .elh,
clean exit under normal load, exit(1) on memory limit exceeded.
Implement compile_test() entry point that emits a C test harness instead
of a normal program. Test blocks (previously skipped) now compile to
static functions with per-assertion pass/fail tracking. Assert statement
added to parser and codegen. Runtime extended with now_ns, fs_list_json,
json_build_object, json_build_array, json_escape_string, state_has,
state_get_or. Fix float negation codegen, float equality comparisons,
time_to_parts return type (JSON string), time_format empty-fmt, json_set
raw-value semantics, state_keys JSON array return. All 310 native tests
pass across 9 suites (core, text, string, math, env, state, json, time, fs).
test "name" { ... } blocks were not recognized by the self-hosted
compiler. The body { } was parsed as a Map literal, creating a huge
AST with O(n²) string concatenation in the toplevel_exec_stmts loop
(which had no arena scope). A 272-line test file would consume 400MB+
and a 720-line file importing the full compiler source caused 150GB
usage and crashed the machine.
Two fixes:
1. Skip Test tokens in codegen_streaming before parse_one() —
advance past "name" and skip_to_rbrace on the body block.
Test blocks are never compiled; self-hosted compiler has no test runner.
2. Add per-statement arena scope to toplevel_exec_stmts emission loop,
matching the el_main_body loop. Frees intermediate strings after
each statement to prevent O(n²) accumulation from any unrecognized
construct that reaches that path.
Result: test_string.el (272 lines, 27 test blocks): 0MB peak (was 400MB+).
test_compiler.el (720 lines + 8728 imported): 15MB peak (was 150GB).
Wrapped compile() body in el_arena_push/pop so the arena is active
before lex() and scan_fn_sigs(). Previously both ran with
_tl_arena_active=0, leaking all token and signature strings permanently.
Also prevents inner pop(mark=0) calls from deactivating the arena
between per-function scopes. Verified: self-host PASS, RSS stable.
