Mako v0.4.1

Mako v0.4.1

365 Mako tests + 81 Rust tests, 0 failures. 11/11 CI jobs green.

Runtime

• Zero-alloc print(f"..."), log_*(f"..."), http_respond(f"...") — f-string bodies consumed directly from the stack buffer, no malloc/free
• writev print on Unix — single syscall for data + newline
• Stored hashes in string-keyed maps — skip memcmp on hash mismatch during probing
• Faster integer hash (splitmix64 replaces wyhash for int-keyed maps)
• Result/Option = {0} aggregate init instead of memset
• Fix memory leaks in wrap_err, error_join, error_tag
• Map probe MAKO_LIKELY branch hints

Codegen

• len(f"...") computes length from stack buffer without materializing a string
• Skip redundant old-pointer save on s = append(s, v) self-append
• emit_fstring_as_view / emit_fstring_view_call helpers for zero-alloc f-string consumers

Performance

• Inline introsort with corrected depth limit and linear sorted/reverse fast paths
• Map key ownership: avoid cloning fresh string keys (literals, interpolation, concatenation)
• Workload: ~23M req/s — tied with Rust, 2x faster than C and Go

Build

• Windows storage I/O: direct fd, mmap, WAL primitives
• Portable temp paths for Windows filesystem tests
• Fix Windows CI: skip plugin compilation test when cc is unavailable
• All 11 CI jobs pass: Ubuntu, macOS, Windows, ASan, UBSan, TSan, GCC, cross-compile, bench gates, claims

Mako v0.4.0

v0.4.0 — Performance, DCE, lint, runtime speed

362 Mako tests + 80 Rust tests, 0 failures. All CI jobs pass.

Performance

• 99.8% C output reduction (30,184 → 64 lines for hello.mko)
• Fast int-to-string (24x faster, no snprintf)
• Realloc string concat (16% faster chained ops)
• Dead code elimination (default-on)
• Demand-driven type helpers (tuples, arrays, channels)
• Compile-time folding: booleans, strings, len, contains, prefix, suffix, repeat, replace

Lint (mako lint)

• Unused imports, unreachable code, unused variables, shadowed variables

Concurrency

• Hardened channel select (thread-local state, seeded stress tests under TSan)

Build

• --strip flag for smaller binaries
• Improved Linux installer (distro detection, profile persistence)

Mako v0.2.5

v0.2.5 — Memory safety audit + LSP + honest docs

357 tests, 0 failures. Full suite passes under AddressSanitizer.

Memory safety (10 codegen ownership bugs fixed)

• Return-from-field clone, consumed-argument transfer, void-call sink
• Arena scope free suppression, stack-view boxing in Result/Option
• Ok/Err/Some transfer_own_on_return, struct-borrow from array indexing
• String/struct array reassign shallow-free
• Save/restore own_drop_live across if-branches
• Source temp marked as moved on reassign

Proven regression test

own_branch_regress_test reproduces the exact if-branch ownership defect:
fails with heap-use-after-free on the pre-fix compiler, passes on this release.

LSP v0.5.0

• Hover, inlay hints, signature help with parameter info

Infrastructure

• Per-test timeout, ASan + UBSan + GCC CI, Windows CI corrected
• Installer: --no-same-owner, graceful read-only shell RC
