fix(ai,nodes): surface database error text from execute and add refresh_schema tool - #2283
nihalnihalani wants to merge 7 commits into
Conversation
…sh_schema tool Two gaps in the shared database node base, both scoped to stay out of the way of the pull requests already open against this file. _executeRawQuery caught every SQLAlchemyError, logged it, and returned None, so execute() answered with the same 'check server logs for details' string whether the statement had a typo, named a missing table, or was refused for permissions. Its except clause now raises with the driver's own message through IGlobal._format_db_error. Only that clause changes: execute()'s `if result is None` branch becomes unreachable but is left in place, with a comment saying so, because an open PR is rewriting that region. Session-bound execute already re-raised the real exception, so the two paths finally agree, and the max_execute_rows rollback is untouched. IGlobal.db_schema is assigned exactly once, in beginGlobal, so get_schema serves a task-start snapshot for the life of the task and a table created through execute stays invisible until the pipeline restarts. The new refresh_schema tool re-reflects and replaces it, returning the get_schema shape plus a refreshed_at UTC timestamp so a caller can show how current the schema it holds is. Reflection and publication run under a module-level lock: concurrent callers would otherwise repeat the same full table walk and race to publish the result. The tool is additive and lives entirely in db_instance_base.py, since another open PR is adding to db_global_base.py. It also fixes the natural-language path, which describes that same dict to the LLM. get_schema's nested table formatter is lifted to a shared private method so both tools render one shape. Tests are a new module rather than an addition to test_db_base.py, which two open PRs are both appending to. Eleven cases over an in-memory SQLite engine cover the driver text reaching the caller, the gate still refusing first, re-reflection seeing created and dropped tables, the timestamp format, and four concurrent refreshes all returning. Tool tables in the four node READMEs that inherit this surface list refresh_schema and say in one sentence what get_schema's snapshot does not show. services.json declares no tool list, so nothing to mirror there.

execute()'s stateless failure path now formats the driver error through IGlobal, but this module builds IGlobal as a SimpleNamespace carrying only the four fields the transaction tests needed. Nothing failed, because no test here drove a bad statement through that path — the next one to try would have died with AttributeError instead of the RuntimeError it was asserting. The stub borrows the real DatabaseGlobalBase implementation rather than a lambda, so the message a test sees is the message a caller gets. A test for the stateless failure path comes with it, so the fixture stays honest: removing the one line makes it fail with AttributeError.

No behaviour change; this only narrows what the previous commit touched in a file three open pull requests are editing. get_schema's body is back to exactly what develop has, docstring aside: the nested _format_table closure returns, and the _format_table static method and _schemaPayload helper it had been lifted into are gone. Sharing them was tidier, but it rewrote a method none of the open PRs needs to change, and a few duplicated formatting lines cost less than that. That hunk is now five added docstring lines instead of a 31-line rewrite. refresh_schema moves to the end of the tool section, below dialect, so the whole tool arrives as one appended block past the execute body PR rocketride-org#1908 rewrites rather than as an insertion ahead of it. It formats its own tables inline, and the lock is now _REFLECT_LOCK. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01T4fLnswQF6yKQ6x7eWzSdd

Two review findings on the READMEs this PR touched, both in the section
the node README schema calls the agent-facing contract and holds to the
highest accuracy bar.
db_postgres listed four tool functions in the summary and in "As a tool",
then a separate table of three transaction tools — seven of the nine
@tool_function methods an agent actually sees on DatabaseInstanceBase.
`execute` appeared only as prose inside the transaction paragraph and
`dialect` only as the QuestionType.DIALECT lane behaviour, so an agent
author reading the inventory would not know either exists as a tool. The
count is now nine in both places, `dialect` joins the open table, and
`execute` joins what was the Transactions table, renamed "Raw SQL and
transactions" because a statement without a session_id is neither. That
table's gate sentence also said requests are "silently dropped" when
allow_execute is off; the four tools raise (db_instance_base.py:301,
339, 371), and it is the questions lane that logs and drops — the two
behaviours are now stated apart. The `execute` row records the driver
message and the rollback-on-overflow that this PR's own change produced,
rather than implying a truncated result set.
rocketride_sql named refresh_schema in its tool table but left its
contract out of the prose beneath, where that README already documents
every other non-obvious argument and return shape. It takes no arguments
(input_schema declares no properties) and returns {database, tables}
exactly as get_schema does, plus a refreshed_at UTC ISO-8601 timestamp
from datetime.now(timezone.utc).isoformat().
Docs only; no behaviour change. Both nodes still pass
scripts/validate-node-readme.py, and so does the whole corpus under
./builder docs:validate.

… text `_format_db_error` only produced a clean `Error <code>: <msg>` when the driver put an integer first in `orig.args` — the pymysql and clickhouse-driver shape. psycopg2 and sqlite3 put a string there, so both fell through to `str(exc)`, which for a SQLAlchemy StatementError is the full repr: the executed statement in `[SQL: ...]` and the values bound into it in `[parameters: ...]`. That string is no longer log-only. `_executeRawQuery` re-raises it as a RuntimeError that the `execute` tool returns to its caller, and rocketride-org#2282 wires a user-facing Refresh/Run UI onto exactly that path, so a failed INSERT would hand the caller back the row it tried to write. Unwrap each driver shape explicitly and keep only the primary message: the numeric-code branch as before; psycopg2's `diag.message_primary` (its `str()` also carries a `LINE n:` echo of the statement, which psycopg2 has already interpolated the bind values into); and `args[0]` for sqlite3 and the generic DBAPI shape. Every branch then runs through `_strip_statement_detail`, which truncates at the first `[SQL:`, `[parameters:`, `LINE n:`, `DETAIL:`/`HINT:`/`CONTEXT:` or sqlalche.me marker, so a driver shape not enumerated here still cannot leak the tail. DETAIL is dropped along with the rest because PostgreSQL uses it to restate the offending key values. The helper is module-level rather than a method so `_format_db_error` keeps working when tests bind it onto a stub IGlobal. Tests cover the real sqlite3 driver end-to-end through `execute`, plus the psycopg2 (with and without `diag`), sqlite3 and pymysql shapes and a bare StatementError repr. `test_format_db_error_falls_back_to_str_when_args_not_int_first` pinned the old leaking fallback, so it is replaced by an assertion that the driver message — not `str(exc)` — is what comes back. `_strip_statement_detail`'s degenerate case gets the same treatment. A message that is nothing but detail markers left no primary sentence, and the old fallback returned the first line — which on that input is the `[SQL: ...]` echo the function exists to remove. It now returns a neutral constant, so there is no input on which the helper hands back the statement. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
`refresh_schema` replaced `IGlobal.db_schema`, the database-wide reflection the natural-language path describes to the LLM, and stopped there. `IGlobal.schema` — the configured table's column map that `_insertData` iterates to build every answers-lane INSERT — is a second start-up snapshot, and it was left untouched, rebuilt only lazily when falsy. So the node was current on one path and stale on the other: after running `ALTER TABLE ... ADD COLUMN` and calling the refresh tool, the LLM path saw the new column while the insert lane kept writing the start-up column set and silently dropped it. The four db node READMEs document both the insert lane and "re-reads the schema from the database", so the documented contract overstated the code. Invalidate the map inside the same reflection lock. Emptying it re-arms the lazy rebuild already at the top of `_insertData`, which reflects through the same `_getTableSchema` call `beginGlobal` uses, so the next insert sees what a freshly started node would. Emptying rather than re-reflecting here keeps the call cheap for a node with no answers lane wired, and makes the write a single atomic rebind: a concurrent `_insertData` either reads the old map or finds it falsy and rebuilds, never a half-built dict. Invalidating the map is only safe once `_insertData` stops binding a generated primary key, so that is fixed in the same commit. `_createTableFromData` curates `IGlobal.schema` down to the data columns for an auto-created table, because the `id` it prepends is generated by the database; a map built by reflection carries `id` instead. Since `_insertData` binds NULL for any schema column the rows do not supply, swapping the curated map for a reflected one would have started binding `id=None` on every later insert — tolerated by SQLite's rowid alias, a not-null violation against the `id SERIAL NOT NULL` Postgres renders for the same column. `_insertData` now drops primary-key columns that no row in the batch supplies, decided once per batch so every mapping handed to executemany keeps an identical key set. The two maps therefore produce the same INSERT and refreshing cannot change answers-lane behaviour mid-task. It also fixes the same NULL bind on the path that always reflected: a table that already existed when `beginGlobal` ran. Tests cover the refreshed insert picking up a new column, the pre-existing stale behaviour it fixes, a dropped configured table leaving a falsy map, and — by asserting on the compiled INSERT rather than on what SQLite tolerates — that an auto-created table's insert still carries the data columns only after a refresh, that a reflected primary key the rows do not supply is omitted, that one they do supply is still bound, and that a primary-key-only table falls back to binding it.

The `Raw SQL and transactions` section said `allow_execute` is "the same gate as `QuestionType.EXECUTE`" and contrasted the tools with "the `questions` lane, which logs and drops the request". No SQL database node implements that branch: `DatabaseInstanceBase.writeQuestions` does not look at `question.type` at all, and `QuestionType` appears in db_instance_base.py only at the import and in one unrelated `Question(type=QuestionType.QUESTION, ...)` construction. The dispatch-on-type behaviour belongs to the graph node (`graph_instance_base.py` handles `DIALECT` and `EXECUTE`), and the wording was carried across without being checked against this file. Correct it wherever it appears in prose: - db_postgres: the "Two special question types are handled on the questions lane" bullets are removed — the lane has one behaviour, translate-then-execute, and `dialect` / `execute` are the tool functions that reach those behaviours. The gate sentence now says what `allow_execute` gates (the four raw-SQL tools) and that it does not change the questions lane, which never runs raw SQL. - rocketride_sql: same two claims, in the config and Notes sections. Also make the refresh_schema wording match the code now that the tool invalidates the answers-lane column map as well as the database-wide schema, so "re-reads the schema from the database" is true end to end rather than only for the LLM path. The same claim lived in the generated config tables, whose source of truth is the `allow_execute` field description in each node's services*.json. Those five descriptions now name the four tool functions the flag actually gates, and the generated regions are regenerated from them, so db_postgres/README.md no longer contradicts itself between its prose and its parameter table. Only the SQL nodes are touched: the graph nodes do dispatch on `QuestionType.EXECUTE`, so their copy is correct as it stands. Two smaller instances of the same transposition: the new db_postgres sentence named `db_neo4j`, a retired path that redirects to `graph_neo4j`, and db_clickhouse/IInstance.py said its dialect string is "surfaced via QuestionType.DIALECT" when only the `dialect` tool reaches it.

In `@nodes/src/nodes/db_clickhouse/README.md`:
- Around line 60-62: Update the README text describing cached column-map refresh
to remove the nonexistent “answers” insert lane reference, while preserving the
accurate description of schema refresh behavior and ensuring lane and connection
descriptions match the node’s declared inputs.
In `@nodes/src/nodes/db_postgres/README.md`:
- Line 80: Update the README description of get_schema and refresh_schema to
accurately state that get_schema serves the current cached IGlobal.db_schema
snapshot, while refresh_schema replaces that database-wide cache and invalidates
IGlobal.schema for lazy reconstruction on the next insert. Keep the description
aligned with the node implementation and configured service behavior.
- Line 64: Update the README description of the questions lane to state that
every question uses the natural-language processing path, but only valid
generated SQL is executed; when writeQuestions receives isValid: false, it
returns the prose answer without calling _executeSQLQuery. Remove the claim that
every question is executed while preserving the distinction from dialect and
raw-SQL tool functions.
In `@packages/ai/src/ai/common/database/db_global_base.py`:
- Around line 120-123: The raw execute error handling around _DB_ERROR_DETAIL
currently exposes driver-specific messages and submitted literals to callers.
Update _executeRawQuery to format failures with a generic safe fallback or
stable category, while retaining the complete exception details in server-side
logs; add regression coverage for PostgreSQL and MySQL errors containing
literals.
In `@packages/ai/src/ai/common/database/db_instance_base.py`:
- Line 457: Update _insertData to hold _REFLECT_LOCK across the falsy-schema
check, _getTableSchema rebuild, and schema snapshot copy, then use that copied
snapshot for all insert operations so concurrent inserts cannot observe a
partially rebuilt or mutating IGlobal.schema.
- Around line 897-901: Update the batch mapping logic around supplied_keys and
omit_columns to partition rows by whether generated primary-key columns are
present, then execute each homogeneous group with its consistent column set.
Ensure rows omitting generated keys exclude those columns so database defaults
apply, while rows supplying them retain the columns and values.
- Around line 902-905: Update the insert logic around the omit_columns fallback
so a table containing only a database-generated primary key uses a DEFAULT
VALUES insert instead of binding NULL. If that sole key is not generated, reject
the missing required value, and update
test_insert_binds_the_primary_key_when_it_is_the_only_column to cover the
revised behavior.

Remove the nonexistent answers insert lane.
This node declares no answers input lane. The new text incorrectly states that schema refresh affects inserts on that lane.

| - **`QuestionType.EXECUTE`**: runs the question text as raw SQL (read or write, no LLM, no safety check). Gated by `allow_execute`; when disabled the request is logged and dropped. `SELECT` results are capped at 25,000 rows; write statements report `affected_rows`. | ||
| The `questions` lane has one behaviour: every question is translated to SQL and executed. It does not branch on `Question.type` — there is no dialect or raw-SQL path on the lane, so a `QuestionType.DIALECT` or `QuestionType.EXECUTE` question is handled exactly like any other natural-language question. (The graph node `graph_neo4j` *does* dispatch on those two types; this node never has.) Reach the dialect and raw-SQL behaviours through the `dialect` and `execute` tool functions below instead. |

Do not state that every question is executed.
If the LLM returns isValid: false, writeQuestions emits its prose answer without calling _executeSQLQuery. State that every question uses the natural-language processing path, and that only valid generated SQL is executed.

| `get_schema` serves the schema reflected when the node started, so a table created or altered since is invisible to it; `refresh_schema` takes no arguments and re-reflects the database. It refreshes both caches the node keeps: the database-wide schema that the natural-language path describes to the LLM, and the configured table's column map that the `answers` lane builds its INSERTs from — so a column added by DDL is populated on the next insert instead of being dropped as unknown. |

Describe the two cache updates precisely.
After refresh_schema, get_schema serves the refreshed IGlobal.db_schema, not the startup snapshot. The method also invalidates IGlobal.schema; it does not rebuild that column map until the next insert.
Describe get_schema as serving the current cached snapshot. State that refresh_schema replaces the database-wide cache and invalidates the insert cache for lazy reconstruction.

Synchronize the lazy schema rebuild with schema readers.
After this assignment, _insertData rebuilds the cache through _getTableSchema. That method sets IGlobal.schema = {} and then adds columns incrementally.
A concurrent insert can see the partially populated dictionary. It can omit incoming columns or fail while iterating a dictionary that changes size.
Use _REFLECT_LOCK around the falsy check, rebuild, and snapshot copy in _insertData. All insert operations must use the copied snapshot.

Handle mixed primary-key presence per row group.
supplied_keys is the union of keys from the complete batch. If one row supplies id and another row omits it, id remains in every mapping. The row without id then binds NULL instead of using the generated value. PostgreSQL rejects the complete batch for a SERIAL NOT NULL key.
Partition rows into homogeneous groups based on generated-key presence. Execute each group with a consistent column set.

Use a default-values insert for a generated-only table.
This fallback binds the sole primary key as NULL. SQLite accepts this for an integer rowid alias, but PostgreSQL rejects NULL for a generated SERIAL NOT NULL key.
If the sole column is database-generated, issue a default-values insert instead. If it is not generated, reject the missing required key. Update test_insert_binds_the_primary_key_when_it_is_the_only_column accordingly.
