- parser: clause keywords (header, format, status, user, csv, ...) now work
as identifiers everywhere; IMPORT/EXPORT accept FORMAT csv/HEADER true
- nimble test + CI run all 13 test suites (650 checks green)
- ExecutionContext.registry is now {.cursor.} (breaks registry<->ctx cycle)
- ORC crash reproduced and bisected (tests/orc_repro.py); ARC stays the MM
Core storage: hash MemTable, WAL group commit, L0 compaction rebuild,
reader-writer lock, and a global StorageGate so HTTP workers and TCP
share the LSM safely under multi-thread access.
Schema: durable CREATE/ALTER/DROP under _schema:tables:* with full LSM
restore on open. Executor types/values/schema split into query/exec/.
Wire protocol: switch default MM to ARC — ORC cycle collector segfaulted
after ~20 async INSERTs. Fair multi-tier benchmarks (SQLite/HTTP/wire/PG)
and honesty docs for mixed-tier comparisons.
- Add --path:src and --threads:on to nim.cfg so tests compile without manual flags
- Add tests/config.nims for automatic path resolution in test directory
- Simplify nimble task definitions (remove redundant flags now in nim.cfg)
- Fix Dockerfile.source comment: remove obsolete nimmax reference
This makes 'nim c tests/test_all.nim' and 'nimble test' work out of the box.
Поправени проблеми:
- MVCC: aborted транзакции вече не стават видими (добавено abortedTxns множество)
- LSM-Tree: поправена загуба на данни при immutable memtable overwrite
- LSM-Tree: поправена SSTable search order (сортиране по id вместо minKey)
- WAL: sync()/close() вече извикват posix.fsync()
- Auth: simpleHash (djb2) заменен с HMAC-SHA256
- Recovery: summary() вече не мутира базата данни
- Raft: поправена majority calculation за четен брой нодове
- Query: EXISTS subqueries вече изпълняват подзаявката
- Nimble: поправен build (-d:ssl) и bench task
