From f1de5e6d184fa315e664bcf8f034c58eafcb6535 Mon Sep 17 00:00:00 2001 From: Boris Tyshkevich Date: Sat, 8 Aug 2026 14:22:27 +0200 Subject: [PATCH 01/13] feat(#630): add authenticatedResponse to the authenticated request seam Phase 7 checkpoint 1 (plan sections 5, 23): compose authenticatedRequest with the package's ensureClickHouseSuccess classifier so a caller that must own its own byte-stream consumption (raw export, later checkpoints) can get back the exact successful native Response, untouched, with a non-2xx status raised as the package's ClickHouseError. authenticatedRequest remains sole owner of token/epoch/refresh/lifecycle; this adds exactly one classification after settlement, no retry, no second fetch. Adds unit coverage for Response identity, unread body, non-2xx -> ClickHouseError, abort/network TypeError identity propagation, and unchanged one-refresh-then-classify bounds.

Format/settings mapping matches the retired net/ch-client.ts runQuery exactly, including applying a positive rowLimit cap uniformly across all four format branches (plan §2.5) and keeping the script over-fetch cap in params, spread after stmt.params so it always wins a collision, never duplicated into settings (plan §2.3/§8). ExportService (src/application/export-service.ts) now uses exportResponse/runEffectText (mirroring authenticatedResponse/ authenticatedText) instead of exportQuery/runQuery, deleting its own resp.ok/resp.text() classification path — package HTTP success classification happens once via authenticatedResponse, and the successful Response stays unread until streamToFile's own body.getReader(). Both explicit cancel paths (grid Cancel button and Export's own Cancel) now go through a single owner-scoped cancelOwnedQuery(ownerEpoch, queryId) callback in app.ts, which fences a replacement (non-owner) authenticated-execution-scope epoch via conn.captureCancellationLease before reaching the frozen kill — local abort always happens before the best-effort remote KILL QUERY. Owner epoch is captured once at operation registration/start (workbench ActiveRun.ownerEpoch; ExportService's exportOwnerEpoch/ exportScriptOwnerEpoch), never re-read at cancel time. app.ts wires QES/ExportService's authenticated primitives directly over authenticatedProgress/authenticatedText/authenticatedResponse (net/authenticated-clickhouse-request.ts) against the live chCtx, and carries the documented killWithLease bridge cast so ch.killQueryWithLease keeps compiling with its still-required 3rd sqlString argument until a later sub-task drops it. Deviations from the declared file scope, both required to keep the shared `npm run check:types` gate green and explained here rather than silently expanded: tests/spike/clickhouse-client/parity.test.ts and live-sessions.test.ts needed a small compile-compat adapter (runTextViaShim) bridging their pre-Phase-7 (ctx, sql, RunQueryOptions) shims to QueryExecutionDeps's new shape — NOT the real Checkpoint 2C spike retarget (plan §19), which is a later sub-task's job. runQuery/exportQuery/ordinary killQuery still exist in net/ch-client.ts (their own tests keep them covered) — only production QES/ExportService/ app.ts consumers stop using them, per plan §21/Checkpoint 2D (deletion) being a later sub-task. Full local gate green: check:types, check:arch, check:schemas, check:examples, npm test (225 files / 7386 tests, 100/100/97.11/100 coverage, no per-file floor violations), npm run build.

candidate-entry.ts's tree-shaking retention list follows the rename. No spike .ts file (excluding run-matrix.mjs/run-matrix.test.ts, owned by a separate sub-task) imports/type-references runQuery, exportQuery, RunQueryOptions, or RunQueryResult anymore.

Under real parallel Chromium+WebKit load this occasionally let the whole 3000ms server-side hold elapse before the delayed timer fired, racing the export to normal EOF completion instead of cancelling it (observed flake: movedToPartial null since retainPartial's move() never fired), and WebKit was separately observed splitting the initial burst into more than one native read/progress pair, breaking the exact-count assertions. Fixes: - Schedule the cancel synchronously from inside the FIRST update() callback (same deterministic, load-independent technique clickhouse-http-transport.spec.js's own Scenario 6/7/9 already use) instead of a wall-clock wait. - Relax the pre-cancel assertions to ">=1 progress/write pair" and "committed bytes > 0" (the amount actually written is bytes-received minus the 32 KiB still held back, not itself > 32 KiB) rather than assuming exactly one native read delivers the whole first chunk. Verified with 20 consecutive chromium+webkit runs, all green (previously flaky within single-digit repeats).

One deferred microtask lands after the loop's synchronous continuation has issued the next read, making the mid-read-abort genuinely true while staying deterministic under parallel Chromium+WebKit load like the prior synchronous version.
