# Ring Benchmark Results
Generated by `lib/erlang/bench_ring.sh` against `sx_server.exe` on the
synchronous Erlang-on-SX scheduler.
| N (processes) | Hops | Wall-clock | Throughput |
|---|---|---|---|
| 10 | 10 | 907ms | 11 hops/s |
| 50 | 50 | 2107ms | 24 hops/s |
| 100 | 100 | 3827ms | 26 hops/s |
| 500 | 500 | 17004ms | 29 hops/s |
| 1000 | 1000 | 29832ms | 34 hops/s |
(Each `Nm` row spawns N processes connected in a ring and passes a
single token N hops total — i.e. the token completes one full lap.)
## Status of the 1M-process target
Phase 3's stretch goal in `plans/erlang-on-sx.md` is a million-process
ring benchmark. **That target is not met** in the current synchronous
scheduler; extrapolating from the table above, 1M hops would take
~30 000 s. Correctness is fine — the program runs at every measured
size — but throughput is bound by per-hop overhead.
Per-hop cost is dominated by:
- `er-env-copy` per fun clause attempt (whole-dict copy each time)
- `call/cc` capture + `raise`/`guard` unwind on every `receive`
- `er-q-delete-at!` rebuilds the mailbox backing list on every match
- `dict-set!`/`dict-has?` lookups in the global processes table
To reach 1M-process throughput in this architecture would need at
least: persistent (path-copying) envs, an inline scheduler that
doesn't call/cc on the common path (msg-already-in-mailbox), and a
linked-list mailbox. None of those are in scope for the Phase 3
checkbox — captured here as the floor we're starting from.

;; Compile-mode flag: "compiling" on the state.

;; lib/js/regex.sx — pure-SX recursive backtracking regex engine
;;
;; Installed via (js-regex-platform-override! ...) at load time.
;; Covers: character classes (\d\w\s . [abc] [^abc] [a-z]),
;; anchors (^ $ \b \B), quantifiers (* + ? {n,m} lazy variants),
;; groups (capturing + non-capturing), alternation (a|b),
;; flags: i (case-insensitive), g (global), m (multiline).
;;
;; Architecture:
;; 1. rx-parse-pattern — pattern string → compiled node list
;; 2. rx-match-nodes — recursive backtracker
;; 3. rx-exec / rx-test — public interface
;; 4. Install as {:test rx-test :exec rx-exec}

## Notes
- The spec interpreter is correct but slow (call/cc + dict-based ivars per send).
- Larger Life multi-step verification, the 8-queens canonical case, and the glider-gun pattern are deferred to the JIT path.
- Generated by `bash lib/smalltalk/conformance.sh`. Both files are committed; the runner overwrites them on each run.

;; SUnit — minimal port written in SX-Smalltalk, run by smalltalk-load.
;;
;; Provides:
;; TestCase — base class. Subclass it, add `testSomething` methods.
;; TestSuite — a collection of TestCase instances; runs them all.
;; TestResult — passes / failures / errors counts and lists.
;; TestFailure — Error subclass raised by `assert:` and friends.
;;
;; Conventions:
;; - Test methods are run in a fresh instance per test.
;; - `setUp` is sent before each test; `tearDown` after.
;; - Failures are signalled by TestFailure; runner catches and records.
