dailz	ef26481976	style: apply rustfmt across bench and core crates ... Pure formatting pass - no semantic changes. Mostly long-line reflow, import statement reordering (alphabetical), and trailing-newline fixes that had been accumulating in the working tree. Affected files: * crates/bench/src/{data_gen,main,mmap_reader,pread_reader,report,runner}.rs * crates/bench/src/suites/{concurrent,growth,jump,memory,render,rotation,startup}.rs * crates/core/src/io/{file_reader,index_cache,read_cache}.rs * crates/core/src/{types.rs, watcher/file_watcher.rs}	2026-06-22 16:38:28 +08:00

dailz	a8b64e78bd	fix(bench): stabilize report column/row ordering across input permutations (#39) ... - variants: use direct tuple comparison instead of format! string, add sort() after dedup - Memory section: sort rows by (test_name, backend, variant) before output - Extra Metrics section: sort rows by (test_name, variant_label) before output - add [lib] target to Cargo.toml to enable unit tests - add regression test: same data in different input order produces identical report	2026-06-05 16:24:41 +08:00
dailz	dad5f5a635	fix(bench): eliminate SIGBUS handler static mut UB with Once + raw atomics (closes #33) ... Replace `static mut OLD_SIGBUS_HANDLER` with AtomicU8 + AtomicPtr to remove data race UB when concurrent benchmarks call open() from multiple threads. Key changes: - Use `Once::call_once` to guarantee single handler installation - Publish old handler to atomics BEFORE installing new handler (closes the handler-active-but-state-unpublished race window) - Read atomics with Acquire in signal handler (async-signal-safe) - Align si_addr to page boundary before mmap(MAP_FIXED) - Add concurrent test: 8 threads open all 5 variants simultaneously	2026-06-05 13:22:02 +08:00
