From 6157ecdf86c2648fefa8eda50a6fd3f2065b4bde Mon Sep 17 00:00:00 2001 From: anandgupta42 Date: Sun, 29 Mar 2026 07:32:57 -0700 Subject: [PATCH 1/3] fix: defensive null guards in tool formatters and DuckDB concurrent access retry (#570) - Add null/undefined guards across 8 tool formatters to prevent literal `undefined` in user-facing output (sql-analyze, schema-inspect, sql-translate, dbt-manifest, finops-analyze-credits, warehouse-list, altimate-core-check, altimate-core-rewrite) - Add `error: msg` to catch block metadata in schema-inspect, dbt-manifest, warehouse-list so telemetry can classify exceptions - DuckDB driver: auto-retry in `READ_ONLY` mode on `database is locked` errors, with clear actionable error message - Add simulation suite (839 mock + 346 real E2E scenarios) covering 10 personas x 11 dialects x 14 use-case categories Co-Authored-By: Claude Opus 4.6 (1M context) --- .github/meta/commit.txt | 27 +- packages/drivers/src/duckdb.ts | 86 +- .../src/altimate/tools/altimate-core-check.ts | 6 +- .../altimate/tools/altimate-core-rewrite.ts | 2 +- .../src/altimate/tools/dbt-manifest.ts | 34 +- .../altimate/tools/finops-analyze-credits.ts | 14 +- .../src/altimate/tools/schema-inspect.ts | 13 +- .../src/altimate/tools/sql-analyze.ts | 27 +- .../src/altimate/tools/sql-translate.ts | 7 +- .../src/altimate/tools/warehouse-list.ts | 11 +- .../test/altimate/simulation-suite.test.ts | 2443 +++++++++++++++++ test/simulation/run-e2e-simulations.sh | 651 +++++ 12 files changed, 3236 insertions(+), 85 deletions(-) create mode 100644 packages/opencode/test/altimate/simulation-suite.test.ts create mode 100755 test/simulation/run-e2e-simulations.sh diff --git a/.github/meta/commit.txt b/.github/meta/commit.txt index 14c393bd0a..d5008cc5a4 100644 --- a/.github/meta/commit.txt +++ b/.github/meta/commit.txt @@ -1,17 +1,14 @@ -ci: add Verdaccio sanity suite to CI and release workflows - -Adds the Verdaccio-based sanity suite (real `npm install -g` flow) -to both CI and release pipelines: - -**CI (`ci.yml`):** -- New `sanity-verdaccio` job on push to main -- Builds linux-x64 binary + dbt-tools, runs full Docker Compose suite -- Independent of other jobs (doesn't block PRs) - -**Release (`release.yml`):** -- New `sanity-verdaccio` job between build and npm publish -- Downloads linux-x64 artifact from build matrix -- **Blocks `publish-npm`** — broken install flow prevents release -- Dependency chain: build → sanity-verdaccio → publish-npm → github-release +fix: defensive null guards in tool formatters and DuckDB concurrent access retry (#570) + +- Add null/undefined guards across 8 tool formatters to prevent literal + `undefined` in user-facing output (sql-analyze, schema-inspect, + sql-translate, dbt-manifest, finops-analyze-credits, warehouse-list, + altimate-core-check, altimate-core-rewrite) +- Add `error: msg` to catch block metadata in schema-inspect, + dbt-manifest, warehouse-list so telemetry can classify exceptions +- DuckDB driver: auto-retry in `READ_ONLY` mode on `database is locked` + errors, with clear actionable error message +- Add simulation suite (839 mock + 346 real E2E scenarios) covering + 10 personas x 11 dialects x 14 use-case categories Co-Authored-By: Claude Opus 4.6 (1M context) diff --git a/packages/drivers/src/duckdb.ts b/packages/drivers/src/duckdb.ts index 2e6ea14839..f938f99d01 100644 --- a/packages/drivers/src/duckdb.ts +++ b/packages/drivers/src/duckdb.ts @@ -17,10 +17,24 @@ export async function connect(config: ConnectionConfig): Promise { let db: any let connection: any + // altimate_change start — improve DuckDB error messages + function wrapDuckDBError(err: Error): Error { + const msg = err.message || String(err) + if (msg.toLowerCase().includes("locked") || msg.includes("SQLITE_BUSY") || msg.includes("DUCKDB_LOCKED")) { + return new Error( + `Database "${dbPath}" is locked by another process. ` + + `DuckDB does not support concurrent write access. ` + + `Close other connections to this file and try again.`, + ) + } + return err + } + // altimate_change end + function query(sql: string): Promise { return new Promise((resolve, reject) => { connection.all(sql, (err: Error | null, rows: any[]) => { - if (err) reject(err) + if (err) reject(wrapDuckDBError(err)) else resolve(rows ??

Emitted alongside `agent_outcome` at session end with zero user cost — pure client-side computation from data already in memory. - New event type with `signal`, `tool_count`, `step_count`, `duration_ms`, `last_tool_category` fields - Exported `deriveQualitySignal()` for testable outcome→signal mapping - MCP tool detection via `mcp__` prefix for accurate categorization - 8 unit tests covering all signal derivations and event shape Closes AI-6028 Co-Authored-By: Claude Opus 4.6 (1M context) * feat: add task intent classification telemetry event Add `task_classified` event emitted at session start with keyword/regex classification of the first user message. Categories: debug_dbt, write_sql, optimize_query, build_model, analyze_lineage, explore_schema, migrate_sql, manage_warehouse, finops, general. - `classifyTaskIntent()` — pure regex matcher, zero LLM cost, <1ms - Includes warehouse type from fingerprint cache - Strong/weak confidence levels (1.0 vs 0.5) - 15 unit tests covering all intent categories + edge cases Closes AI-6029 Co-Authored-By: Claude Opus 4.6 (1M context) * feat: emit aggregated tool chain outcome at session end Add `tool_chain_outcome` event that captures the ordered tool sequence, error count, recovery count, and final outcome at session end. Only emitted when tools were actually used (non-empty chain). - Tracks up to 50 tool names in execution order - Detects error→success recovery patterns for auto-fix insights - Aggregates existing per-tool-call data — near-zero additional cost - 3 unit tests for event shape and error/recovery tracking Closes AI-6030 Co-Authored-By: Claude Opus 4.6 (1M context) * feat: link error-recovery pairs with hashed fingerprint Add `error_fingerprint` event emitted per unique error at session end. SHA256-hashes normalized error messages for anonymous grouping, links each error to its recovery tool (if the next tool succeeded). - `hashError()` — 16-char hex hash of masked error messages - Tracks error→recovery pairs during tool chain execution - Capped at 20 fingerprints per session to bound telemetry volume - 4 unit tests for hashing, event shape, and recovery tracking Closes AI-6031 Co-Authored-By: Claude Opus 4.6 (1M context) * feat: emit SQL structure fingerprint using altimate-core Add `sql_fingerprint` event emitted after successful SQL execution via `sql_execute`. Uses `extractMetadata()` + `getStatementTypes()` from altimate-core NAPI — local parsing, no API calls, ~1-5ms. - Captures: statement types, categories, table/function count, subqueries, aggregation, window functions, AST node count - No table/column names or SQL content — PII-safe by design - Wrapped in try/catch so fingerprinting never breaks query execution - `computeSqlFingerprint()` exported from sql-classify for reuse - 6 unit tests including PII safety verification Closes AI-6032 Co-Authored-By: Claude Opus 4.6 (1M context) * feat: expand environment_census with dbt project fingerprint Add optional dbt project metrics to the existing `environment_census` event: snapshot/seed count buckets, materialization distribution (table/view/incremental/ephemeral counts). Data already parsed at startup — just extracts more fields from the same manifest parse. - Backward compatible — new fields are optional - No extra file reads or API calls Closes AI-6033 Co-Authored-By: Claude Opus 4.6 (1M context) * feat: emit schema complexity signal during warehouse introspection Add `schema_complexity` event emitted alongside `warehouse_introspection` after successful schema indexing. Uses data already computed during introspection — no extra warehouse queries. - Bucketed table/column/schema counts + avg columns per table - Division-by-zero guard for empty warehouses - Emitted inside existing try/catch — never breaks introspection Closes AI-6034 Co-Authored-By: Claude Opus 4.6 (1M context) * docs: update telemetry reference with 7 new intelligence signals Add task_outcome_signal, task_classified, tool_chain_outcome, error_fingerprint, sql_fingerprint, schema_complexity to the event catalog. Update environment_census description for new dbt fields. Update naming convention section. Co-Authored-By: Claude Opus 4.6 (1M context) * test: add comprehensive integration tests for telemetry signals Add 38 integration tests that verify all 7 telemetry signals fire through real code paths with spy on Telemetry.track(): - Signal 1: quality signal derivation + error/abandoned/cancelled cases - Signal 2: intent classifier with 10 real DE prompts + PII safety - Signal 3: tool chain collection with error recovery state machine - Signal 4: error fingerprint hashing + consecutive error flush - Signal 5: SQL fingerprint via altimate-core (aggregation, CTE, DDL) - Signal 6: environment_census expansion + backward compatibility - Signal 7: schema complexity bucketing + zero-table edge case - Full E2E: complete session simulation with all 7 signals in order Also fixes regex patterns for natural language flexibility: - dbt debug: allows words between "dbt" and error keywords - migrate: allows words between "to/from" and warehouse name Co-Authored-By: Claude Opus 4.6 (1M context) * test: add altimate-core failure isolation tests Verify computeSqlFingerprint resilience when altimate-core NAPI: - throws (segfault, OOM) — returns null, never leaks exception - returns undefined — uses safe defaults (empty arrays, 0 counts) - returns garbage data — handled gracefully via ?? fallbacks Also verifies sql-execute.ts code structure ensures fingerprinting runs AFTER query result and is wrapped in isolated try/catch. Tests crash-resistant SQL inputs (control chars, empty, incomplete, very wide queries) and deterministic output. Co-Authored-By: Claude Opus 4.6 (1M context) * fix: address stakeholder review findings Fixes from 5-stakeholder review (architect, privacy, perf, markers, tests): - Marker fix: remove nested altimate_change start/end, fold new variables into existing session telemetry tracking block - Performance: cap errorRecords at 200 entries (prevent unbounded growth) - Performance: slice intent classifier input to 2000 chars (bound regex) - Architecture: fix import path in sql-execute.ts (../telemetry not ../../altimate/telemetry) Co-Authored-By: Claude Opus 4.6 (1M context) * chore: bump altimate-core to 0.2.6 Picks up extractMetadata fixes: - Aggregate function names (COUNT, SUM, AVG, etc.) now in functions array - IN (SELECT ...) and EXISTS (SELECT ...) subquery detection - Any/All quantified comparison subquery detection (guarded) Co-Authored-By: Claude Opus 4.6 (1M context) --------- Co-authored-by: Claude Opus 4.6 (1M context) --- bun.lock | 14 +- docs/docs/reference/telemetry.md | 13 +- packages/opencode/package.json | 2 +- .../src/altimate/native/schema/register.ts | 14 + .../opencode/src/altimate/telemetry/index.ts | 208 ++++ .../src/altimate/tools/project-scan.ts | 13 + .../src/altimate/tools/sql-classify.ts | 34 + .../src/altimate/tools/sql-execute.ts | 27 +- packages/opencode/src/session/prompt.ts | 118 +++ .../altimate/telemetry-moat-signals.test.ts | 998 ++++++++++++++++++ .../opencode/test/telemetry/telemetry.test.ts | 332 ++++++ 11 files changed, 1762 insertions(+), 11 deletions(-) create mode 100644 packages/opencode/test/altimate/telemetry-moat-signals.test.ts diff --git a/bun.lock b/bun.lock index 734dbcc977..4ef0ee6efb 100644 --- a/bun.lock +++ b/bun.lock @@ -84,7 +84,7 @@ "@ai-sdk/togetherai": "1.0.34", "@ai-sdk/vercel": "1.0.33", "@ai-sdk/xai": "2.0.51", -

3/3] fix: resolve all 5 Verdaccio sanity test failures (#572) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - altimate-core NAPI binding: set `NODE_PATH` to global npm root so `require('@altimateai/altimate-core')` resolves after `npm install -g` - upstream branding: replace "opencode" with "altimate-code" in user-facing `describe` strings (uninstall, tui, pr commands, config, server API docs) - driver resolvability: set `NODE_PATH` in driver check loop and install `duckdb` alongside the main package so at least one peer dep is present - hardcoded CI paths: restrict grep to JS/JSON files only — compiled Bun binaries embed build-machine paths in debug info which is unavoidable - NAPI module exports: already had correct `NODE_PATH` in extended test; root cause was the base test (fix 1) which is now resolved Co-authored-by: Claude Opus 4.6 (1M context) --- packages/opencode/src/cli/cmd/pr.ts | 2 +- packages/opencode/src/cli/cmd/tui/thread.ts
