Rongsong Shen	b0a5fbb4e9	feat: persist.c WAL writer with chained CRC32 and dedicated fsync pthread (P0-1) ... - Expose persist_t struct concretely in persist.h (opaque pattern deferred) - persist_set_workdir() derives wal/snap paths from workdir+name - persist_init() creates WAL/snap directories, rejects NFS mounts - persist_wal_async() writes WAL entries with chained CRC32 via zlib - Dedicated fsync pthread fires every wal_sync_ms milliseconds - persist_flush() forces fdatasync for tests and clean shutdown - WAL_CHECKPOINT type rejected with -EINVAL (never written via async path) - Stubs: persist_recover, persist_wal_sync_append, persist_checkpoint - Add fsync_thread_running flag to guard persist_stop when thread not started - Add zlib_dep to controller and unit test meson targets - 3 new TDD tests: init_creates_directories, wal_async_writes_entry, checkpoint_type_rejected — all GREEN	2026-05-07 10:00:10 +00:00
Rongsong Shen	fe69dcbd7a	feat: add persist.h — WAL types, persist_config_t, slot_key_t (P0-B) ... - Define wal_entry_hdr_t (40 bytes, _Static_assert enforced) - Define wal_entry_type enum (WAL_JOB_SUBMIT=1 … WAL_CHECKPOINT=100) - Define persist_config_t with persist_config_defaults() inline helper - Define slot_key_t (index, key[XCE_MAXNAME_LEN], key_len) - Forward-declare persist_t opaque struct and full persist_* API surface - Bootstrap controller Unity test suite (controller_unit_test binary) - Register test('controller test', …, suite: 'controller') in meson - 4 new tests all PASS: wal_header_size, wal_entry_types, persist_config_defaults, slot_key_t_fields	2026-05-07 09:21:36 +00:00
