Devin Review on PR #168 found 5 issues — all real, all addressed.
🚩 ANALYSIS_001 (architectural): concurrent-slot guard didn't protect
actual BQ query execution. Earlier `_enforce_remote_bq_quota_and_cap`
ran dry-run + cap check inside `with quota.acquire(user_id):`, then
returned — releasing the slot BEFORE `analytics.execute(...)` ran. Spec
§4.3.3 explicitly designs the slot to wrap execute so the per-user
concurrent cap limits BQ scans, not just dry-runs.
Refactor to a context manager `_bq_quota_and_cap_guard`. Caller's `with`
block now holds the slot through dry-run, cap check, the actual
`analytics.execute(...)` (which is what triggers the BQ scan when DuckDB
resolves the master view), AND the post-flight record_bytes. Slot
released only when caller's `with` body exits.
🟡 BUG_001: placeholder JS walked `original` (full GET payload root)
instead of `original.sections`. `placeholder_from: ["data_source",
"bigquery", "project"]` is a section-relative path, so billing_project
placeholder NEVER rendered. Fix: walk `original.sections` (with fallback
to `original` for safety).
🟡 BUG_002 + BUG_003: admin_tables.html register and edit modals'
operator help text referenced `max_bytes_per_remote_query` (the old
name from the spec) but the actual config key is `bq_max_scan_bytes`
after the fix-up commit `6423888d` moved it. Replace both occurrences.
🟡 BUG_004: CHANGELOG entry said `api.query.bq_max_scan_bytes` (the
old path) but the read at app/api/query.py:53 is
`get_value("data_source", "bigquery", "bq_max_scan_bytes", ...)`. An
operator who set it under `api.query` in their yaml would have no
effect. Correct path in CHANGELOG.
All 95 #160-affected tests pass after the changes.
Closes the operator-side half of the reporter's loop. The CLI fix in
the previous commit makes USER_PROJECT_DENIED errors readable to
analysts; this commit lets admins verify reachability proactively
from /admin/server-config without waiting for analyst reports.
New endpoint POST /api/admin/bigquery/test-connection
(app/api/admin_bigquery_test.py, ~110 LOC):
- Depends(require_admin); registered in app/main.py.
- Builds BqAccess via existing get_bq_access(), runs `SELECT 1 AS ok`
with a 10s polling timeout.
- 200 with {ok, billing_project, data_project, elapsed_ms} on success.
- 400 for `BqAccessError(not_configured)` (operator config issue).
- 502 for any other typed BqAccessError or unknown upstream exception.
- 504 for concurrent.futures.TimeoutError; best-effort cancel_job
invoked (BQ-side cancel may still run; documented caveat).
Server-config placeholder (app/api/admin.py + admin_server_config.html):
- `data_source.bigquery.billing_project` field-spec gains
`placeholder_from: ["data_source", "bigquery", "project"]`.
- renderLeafInput's text branch reads `opts.spec.placeholder_from`,
walks the loaded `original` config dict, injects
`placeholder="(defaults to <project>)"` into the input HTML at
construction time. Admin sees the access.py:339-340 fallback rule
visible directly in the UI without reading source.
UI button:
- "Test BigQuery connection" button next to data_source's Save button.
- onTestBigQuery() POSTs to the endpoint, renders structured result
inline (green check + elapsed_ms on success; red kind + hint on
failure).
Tests: 6 endpoint cases + 1 placeholder payload test = 7 GREEN. 62
total across the affected admin server-config test files.
Today /admin/server-config renders fields by iterating Object.keys(payload) on the YAML value — if a key isn't in instance.yaml, the operator can't see it. They have to know to type it via the JSON-patch textarea (which only renders for empty sections) or SSH and edit YAML.
Adds a known-fields registry (`_KNOWN_FIELDS` in app/api/admin.py) the UI consumes alongside the YAML payload. Renderer shows BOTH:
- existing fields (from YAML) with current value
- known-but-unset fields with dashed-border placeholder + hint, ready to fill in
Renderer (`renderField`, `renderSection`, `collectSection`):
- kind="string"|"secret"|"bool"|"int"|"select"|"object"|"array"|"map" — picks input type
- kind="object" with `fields` — recursive structured form, arbitrary depth (corporate_memory needs 3-4 levels)
- kind="array" with `item_kind` — vertical stack of typed inputs + add/remove buttons
- kind="map" with `key_kind` + `value_kind` — key:value rows + add/remove (used for confidence.base, domain_owners, entity_resolution.entities)
- data-path encoded as JSON segment array so map keys with embedded dots (e.g. 'user_verification.correction') survive collect → patch round-trip
- .cfg-field.is-unset CSS — dashed border, muted label, italic hint
Sections newly exposed (added to _EDITABLE_SECTIONS):
- openmetadata: url, token (secret), cache_ttl_seconds, verify_ssl
- desktop: jwt_issuer, jwt_secret (secret), url_scheme
Known fields populated for existing sections:
- data_source.bigquery: billing_project (the cause of the 403 USER_PROJECT_DENIED footgun when SA can read but not bill the data project), legacy_wrap_views (bigquery_query() wrap for VIEWs — issue #101 default off, ON for view-heavy deployments), max_bytes_per_materialize (cost guardrail)
- data_source.keboola: stack_url, project_id (hints; values already populated)
- ai: base_url (required for openai_compat), structured_output (select)
- corporate_memory: full schema from instance.yaml.example — distribution_mode, approval_mode, review_period_months, notify_on_new_items, sources.{claude_local_md,session_transcripts}, extraction.{model,sensitivity_check,contradiction_check}, confidence.{base,modifiers,decay.{mode,half_life_months,decay_rate_monthly,floor}}, contradiction_detection.{enabled,max_candidates}, entity_resolution.{enabled,entities}, domain_owners, domains
- Known partial: confidence.modifiers is map<string, map<string, float>> — falls through to JSON-textarea with TODO; structured editor for that one shape needs more renderer work
Tests:
- test_admin_server_config_known_fields — registry envelope shape, smoke fixture
- test_admin_server_config_renderer_depth — 4-level nested objects, arrays of strings, maps of floats, dotted-key safety
- test_admin_server_config_corp_memory — full corporate_memory schema, 12 fields incl. nested
- test_admin_server_config — existing tests adjusted for new shape
Adds /admin/server-config UI for editing instance.yaml from the web. Hardening: SSRF gate on data_source URLs, narrow-overlay write strategy, atomic writes, audit log with secret masking on shape changes, threading lock on read-modify-write, corrupt-overlay refusal on write side + louder log on read side, modal Promise resolution on backdrop dismiss, sentinel scrub on save (defense-in-depth client+server). Bundles Windows PowerShell wrapper from #80. Cuts release v0.13.0.
