sockets + portable HTTP server — 6 primitives, same server runs in all 3
Added tcp-listen/accept/connect/recv/send/close to Python, C, and asm. One examples/http-server.lsp runs identically in all three impls and serves HTTP/1.0 with routing, content-type, and content-length headers. asm additions: - SYS_SOCKET/BIND/LISTEN/ACCEPT/CONNECT/SETSOCKOPT syscalls - 6 tcp-* builtins using the existing port encoding (SPECIAL ≥ 1000) - bi_tcp_connect: dotted-quad IPv4 parser, no DNS dependency Defects fixed along the way (surfaced by the HTTP server): - string-append: was 2-arg only; now variadic (walks arg list twice) - number->string: was stubbed to VAL_VOID; now correctly writes digits into a heap-allocated string (incl. negative handling) - String-literal reader: \r and \0 escape sequences now handled (was silently dropping backslash, treating them as literal 'r' / '0') - tcp_accept: sockaddr buffer was 8 bytes, now 16 (was corrupting caller's stack when accept wrote full struct sockaddr_in) Pinocchio benchmark (tests/web-benchmark.sh): At concurrency=20, 1000 requests, serving a 1KB body: uncommonlisp Python 373 req/s uncommonlisp C 370 req/s uncommonlisp asm 370 req/s python3 http.server 381 req/s (stdlib reference) busybox httpd 382 req/s (production reference) All five converge within 3% — the client (curl fork/exec) is the bottleneck, not the server. Our single-threaded blocking servers are indistinguishable from battle-tested ones at this load. Binary sizes: uncommonlisp asm 45 KB (HTTP + everything else) busybox httpd 2.1 MB (multi-call binary) python3 8 MB (interpreter) The asm HTTP server is 46× smaller than busybox and 176× smaller than Python, serves from 7 Linux syscalls, and the entire protocol handler is 70 lines of portable Scheme. Test counts: 132 asm (up 1), rest unchanged. All green.
