- sql_generator: normalize ISO/epoch values only against a resolved target type (Nullable/LowCardinality unwrapped); untyped epoch-looking strings are preserved and unparseable temporal values raise instead of coercing. Removes the heuristic that wrote sentinel dates (2106-02-07 = UInt32 max) into business date columns. - sql_generator: ClickHouse string-literal escaping — backslash, quote and control characters escaped; ANSI '' doubling alone silently rewrote paths and tabs on insert. - service_target_schema: one fetch_target_column_types resolver for both direct_db and SQL Lab insert paths (300s cache) plus a single column-catalog SQL builder; EXPLORE trace when the catalog is unreachable/empty instead of a silent untyped fallback. - _lang_detect: script-conflict downgrade no longer depends on the target language list; letterless text becomes und; short/number-heavy Cyrillic cannot survive as a Latin language; sanitize_detected_language validates the LLM arbitration answer by script. - _batch_proc/_utils: und rows actually reach LLM arbitration (same-language, cache and preview short-circuits blocked) and trust a cache entry only when its stored source language is confirmed; detector version bumped to invalidate the v2 cache. - _key_mapping: single source->target key mapping; MERGE with target_language_column absent from target_key_cols rejected in preflight before any fetch/LLM; lang_code is a target-only discriminator (no fictitious source key). Removes 5 divergent copies. - frontend: global run indicator elapsed timer (1s tick, server started_at, cleanup) reusing formatDuration; MERGE-key inline validation with en/ru i18n keys; UX contract and decision-memory updates. - tests: real ClickHouse testcontainers coverage on dm.debt_comment_translations (Date32/DateTime transfer, epoch/millis/sentinel/boundaries, NULL semantics, text escaping round-trip, MERGE language discriminator, chunked batch, production projection); unit coverage for typed normalization, escaping, key mapping and the arbitration cache. Existing integration module had a stale untyped-epoch expectation.
Superset Tools Frontend (SvelteKit)
This is the frontend for the Superset Tools application, built with SvelteKit in SPA mode.
Development
-
Install dependencies:
npm install -
Run development server:
npm run devThe frontend will be available at
http://localhost:5173. It is configured to proxy API requests tohttp://localhost:8000.
Production Build
-
Build the static SPA:
npm run buildThis generates a static SPA in the
build/directory. -
Serve with Backend: The Python backend is configured to serve the files from
frontend/build/. Ensure the backend is running:cd ../backend python src/app.py
Architecture
- Routing: File-based routing in
src/routes/. - Layouts: Shared UI in
src/routes/+layout.svelte. - Data Loading:
loadfunctions in+page.tsfor efficient data fetching. - API Client: Centralized API logic in
src/lib/api.js. - Styling: Tailwind CSS.
