dimgigov	2d09edd9f7	fix+refactor: soft keywords as identifiers, full test wiring, ORC crash docs ... - 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	2026-07-30 13:11:28 +03:00
dimgigov	ed5a71913c	fix: harden exception handling, break ARC cycles, sync license/client ... Replace bare except: with CatchableError across storage, query, Raft, backup, and protocol code so Defects are not swallowed. Break uncollectable ARC cycles in server shard/gossip callbacks via Server-owned refs and cursor locals. Align package license with LICENSE (BSD-3-Clause), sync README version, and point test_all at the canonical clients/nim baradb client (parseConnectionString + aliases).	2026-07-23 01:07:51 +03:00
dimgigov	8db5cfe7e1	feat: harden storage, schema persistence, fair benches, fix wire crash ... 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.	2026-07-18 16:55:50 +03:00
dimgigov	aa4ab11210	feat: canonical Nim client refactor with typed rows, pool, and allographer wrapper ... - Extract wire protocol into clients/nim/src/baradb/wire.nim - Add BaraError exception hierarchy - Refactor BaraClient/SyncClient with typedRows, AsyncLock request queue, timeouts, TLS config - Add BaraPool and optional HTTP fallback - Add mock-server wire and pool unit tests - Bump baradb nimble package to 1.2.0 - Make nim-allographer depend on canonical baradb client - Use typed rows in allographer toJson - Deprecate src/barabadb/client/client.nim - Update docs/en/clients.md and clients/nim/README.md	2026-06-18 21:29:55 +03:00
dimgigov	1c42eff7ef	fix(vector): use float64 accumulators for distance functions ... Vector distance functions (cosine, euclidean, dot, manhattan) returned float64 but accumulated sums in float32, causing precision loss in SQL results (e.g. sqrt(2) truncated to float32). Use float64 accumulators and casts throughout. docs(bugs): mark BUG-023 and BUG-024 as fixed The code already cleans up pendingAcks and passes oldAssignments from rebalance to migrateData; update BUGS.md to match the implementation.	2026-06-12 23:06:19 +03:00
dimgigov	ef264d7d69	feat: add unified search engine — HNSW heap-opt, segment index, boolean/phrase/ngram/facet ... New src/barabadb/search/ module with 9 components: - priority_queue.nim: BoundedHeap for O(log n) search - hnsw_opt.nim: heap-based searchLayer (2.4x faster, 92-99% recall@10) - inverted.nim: segment-based index with soft-delete and compaction - phrase.nim: positional phrase + proximity search - boolean.nim: recursive descent parser (AND/OR/NOT/ranges/wildcards) - ngram.nim: trigram index for O(1) fuzzy/prefix/wildcard - stemmer.nim: Porter2 stemmers (EN/BG/DE/FR/RU) - facet.nim: faceted search with filter pushdown - engine.nim: UnifiedSearchEngine combining all search types Performance (dim=128, efConstruction=200): N=1K: 0.30ms search, 99.6% recall@10 N=10K: 1.09ms search, 92.6% recall@10 N=50K: 2.26ms search, 75.5% recall@10 Includes search benchmarks (benchmarks/search_bench.nim), updated docs (en/bg fts.md, en/bg search.md), and crossmodal engine integration.	2026-05-30 13:42:08 +03:00
dimgigov	965ed2f675	perf: optimize FTS and HNSW engines + real PostgreSQL benchmarks ... FTS Engine (src/barabadb/fts/engine.nim): - Fix bm25Score doing O(n) linear scan per document - Cache IDF per token instead of recomputing for each doc - Use entry.termFreq directly instead of searching postings again - Result: FTS search +438% (249 -> 1360 queries/s) HNSW Vector Engine (src/barabadb/vector/engine.nim): - Optimize distance functions with float32 + 4x loop unrolling - Rewrite searchLayer: swap+pop instead of O(n) del, track worst-nearest instead of sorting nearest on every iteration - Result: HNSW insert +117% (245 -> 543 ops/s), search 2.2x faster Benchmarks: - Add real PostgreSQL comparison script (benchmarks/pg_bench.py) - Add report generator (benchmarks/generate_report.py) - Fix compare.nim cpuTime() bug (was dividing by 1M incorrectly) - Add nimble tasks: bench_pg, bench_report Docs: - Update README.md and docs/en/performance.md with real measured numbers - Add benchmarks/REAL_COMPARISON.md Version bump: 1.1.7 -> 1.1.8	2026-05-29 17:11:22 +03:00

dimgigov	0c7847abba	docs: update backup.md with multi-database and HTTP API docs	2026-05-25 18:49:26 +03:00
dimgigov	eb62b381a1	feat: multi-database backup, HTTP API endpoints, admin panel UI ... - backup CLI: add --all-databases, --database, --data-root flags - backup format: tar.gz with databases/<name>/ + backup.json metadata - HTTP API: new endpoints /databases, /backup, /backups, /restore - HTTP API: database switching via X-Database header - Admin panel: database selector dropdown, Databases tab, Backups tab - Admin panel: backup/restore UI with fetch() to new endpoints - Update deps: hunos 1.3.0, jwt-nim-baraba 2.1.0 - Docker: backup cron uses --all-databases --data-root=/data/databases - Docs: update api-http.md, protocol.md with correct endpoints - OpenAPI spec updated to v1.1.6 Known limitation: DELETE /databases disabled due to ORC SIGSEGV in LSMTree.close(). Use SQL DROP DATABASE instead.	2026-05-25 18:46:07 +03:00
dimgigov	a9ea80a1f8	fix(prop_test): "Nil expr evaluates to NULL" test — compare Value.kind, not Value == "" ... The test was comparing a Value to a string literal which always failed. Changed to check s.kind == vkNull on both calls. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>	2026-05-23 22:06:37 +03:00
dimgigov	7d19e06805	fix(btree): critical seq.del vs seq.delete bug and B+ tree leaf traversal ... Root cause: seq.del(i) does swap-with-last (destroys sorted order) while seq.delete(i) preserves order. This caused massive data loss during B-tree removes. Changes: - btree.nim: Replace seq.del with seq.delete (critical data corruption fix) - btree.nim: search() traverses leaf linked list for duplicate boundary keys - btree.nim: splitChild() consolidates duplicate boundary key values before split - btree.nim: len() counts unique keys via leaf traversal - btree.nim: remove() traverses leaf linked list to remove ALL occurrences - btree.nim: Fix separator update in internal node (node.keys[i-1] not [i]) - prop_test.nim: Use set equality for interleaved test (rebalancing reorders) Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>	2026-05-23 22:01:20 +03:00
dimgigov	b25fea4d21	fix: all 5 bugs — reserved words, cloneForConnection, SQL injection, SHOW TABLES, getRowPlain	2026-05-21 22:51:04 +03:00
dimgigov	837b4d56fc	fix(nim-allographer/baradb): critical client fixes and bug audit ... - Export hidden symbols in baradb_client.nim (socket, nextId, readQueryResponse, toString, toBytes) - Add missing imports in baradb_exec.nim (asyncnet, enums, baradb_query) - Rewrite toJson() to use wire protocol columnTypes instead of guessing types from strings - Fix aggregate functions (count, avg, sum) to handle JInt/JFloat/JString correctly - Fix paginate/fastPaginate discard issues - Add placeholder arguments for whereIn/whereNotIn/whereBetween/whereNotBetween - Add placeholder count validation in formatSql() - Fix getRowPlain() to avoid IndexDefect on empty results - Harden transactionStart/transactionEnd against server crashes - Reset placeHolder in insertSql() to avoid stale values - Fix test_query.nim to use backtick quoting for BaraDB compatibility Known server bugs documented in BARADB_CLIENT_BUGS.md	2026-05-21 22:01:55 +03:00
dimgigov	bb843b9a03	feat: migrate system + cross-DB engine + IMPORT/EXPORT syntax -- 22 files, client+server+docs	2026-05-21 19:32:14 +03:00

dimgigov	8a385cba6a	docs(readme): clarify this is a BaraDB fork of nim-allographer	2026-05-21 15:54:56 +03:00
dimgigov	6bfc5b3a3c	feat(clients): add nim-allographer client with BaraDB driver support ... - Pure Nim wire protocol client (async + sync, no C FFI) - Query Builder: fluent API, SQL generator, execution, transactions - Schema Builder: create/alter/drop tables, column operations - Connection pool with aging and timeout handling - ORM integration via compile-time DB_BARADB switch - Tests: test_open, test_query - Documentation: README.md, PLAN_BARADB.md	2026-05-21 15:49:11 +03:00
dimgigov	2d310a33a1	fix: resolve all 55 identified bugs across the codebase ... Comprehensive bug fix pass across all subsystems: - Critical: lexer infinite loop, WAL lock discipline, checkpoint safety, compaction verification, HMAC key truncation, healthCheck leak - High: MVCC lock safety, B-Tree delete rebalancing, Raft stale term handling, replication socket leaks and ack cleanup, sharding migration with old assignments, 2PC recovery, JWT/SCRAM auth fixes, wire protocol bounds checks - Medium: config error handling, MERGE parser completeness, IR/codegen correctness, UDF bounds checks, LIMIT cost accuracy, mmap safety - Low: timeout handling, float parsing edge cases, uint32 truncation, cache entry cleanup Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>	2026-05-21 10:59:51 +03:00
dimgigov	7fc6adbe47	chore: remove old planning and bug report files ... These files are outdated and only cause confusion. Keep only the current PLAN.md.	2026-05-21 09:47:40 +03:00
dimgigov	072e7a5d13	test(join): add test for duplicate columns in SELECT * ... Verify that JOIN with overlapping column names preserves both left (bare) and right (qualified) values.	2026-05-21 09:44:32 +03:00
dimgigov	d4dc433e48	fix(query): preserve both sides of duplicate column names in JOIN ... When SELECT * joins tables with overlapping column names (e.g. 'id' in both users and orders), the right-side value was being dropped because irekStar filtered out dotted keys. - Add expandStarRow() that keeps bare columns and adds qualified aliases (u.id, o.id) only for duplicated names - Fix r.columns expansion to include all joined tables, qualifying duplicates from the right side	2026-05-21 09:44:31 +03:00
dimgigov	1ff6fabaff	fix(backup): resolve relative SSTable paths in incremental backup ... MANIFEST stores relative paths like 'sstables/1.sst'. The old code checked fileExists against CWD instead of dataDir, silently omitting SSTables when run from another directory. Now resolves paths relative to dataDir.	2026-05-21 09:44:28 +03:00
dimgigov	4a83eb6783	docs: update distributed/backup/schema/storage for multi-database ... - Add multi-database limitations to distributed docs - Fix backup commands and add multi-database backup guidance - Add SQL migration section to schema docs - Update storage examples to use per-database paths	2026-05-21 09:44:25 +03:00
dimgigov	a526a3aef9	docs: remove non-English/Bulgarian language docs, fix links ... Remove ar, de, fa, ru, tr, zh documentation folders. Update docs/index.md and docs/bg/index.md to only list en/bg. Update README badge from 7 to 2 languages. Update changelog entry for Bulgarian docs.	2026-05-21 09:44:17 +03:00
dimgigov	372e5cf627	fix(query,types): refactor Row to Value-typed map, fix IN list, nkPath, multi-table joins ... - Refactored Row from Table[string, string] to Table[string, Value] - Added Value operators: ==, !=, $, in for string interop - Fixed valueToString for vkNull to return '\\N' instead of '' - Fixed evalExpr irekField to return vkNull when field not found - Added IN (val1, val2, ...) parser support - Fixed nkPath column names in multi-table joins - Fixed LATERAL JOIN null padding when no matching rows - Added CREATE/DROP/USE/SHOW DATABASE parser support - Adapted all tests for new Value type	2026-05-20 23:22:14 +03:00
dimgigov	57d2908066	fix(executor,mvcc,tests): dedup aliases, fix txn delete, fix MIN/MAX null, add regression tests ... - Add isDelete flag to VersionedRecord to fix COMMIT treating empty values as DELETE. Previously version.xmax != TxnId(0) was never true for active transactions, so deletes inside transactions never removed rows. - Fix MIN/MAX aggregates skipping NULL: was checking for "\\N" instead of correct "\N" sentinel, so NULL values were never skipped. - Add duplicate alias deduplication in lowerSelect() and getSelectColumns(). Identical aliases now get _1, _2 suffixes (e.g. count(*), count(*)_1). - Add nil guard for expr.subqueryPlan in irekSubquery evalExpr handler. - Initialize txnManager in newExecutionContext to prevent segfault on BEGIN. - Add regression tests: DELETE in transaction, PK-only row survival, MIN/MAX NULL skipping.	2026-05-20 21:36:15 +03:00
