Fix database fetch correctness and Testbench cleanup - #18
Conversation
Forward custom PDO fetch arguments through every result set and configure cursor statements once so streamed rows retain fetchAll-compatible column and class defaults.\n\nPreserve null and other falsey cursor values, make pretend cursors yield nothing without resolving PDO state, and cover the behavior directly with SQLite regressions.\n\nRemove Capsule's ineffective connection-wide fetch setter and its unused configuration. Query-scoped fetchUsing() remains the safe public row-shape boundary.
Keep custom fetch modes on row-returning queries while isolating booleans, aggregates, pagination counts, plucks, and scalar helpers behind an exception-safe scoped default. Preserve caller callbacks and fetch state without adding queries or connection-wide mutation.\n\nDistinguish nullable rows from absence, retain null cursor values after callbacks, remove internal group-limit fields from associative rows, restore temporary columns after failures, and make ID iteration independent of PDO-controlled collection keys.\n\nCarry Query Builder key and value types through processors and Eloquent forwarding, and add portable four-engine regressions for terminal shapes, cursor pagination, streaming, pagination, callbacks, and iteration positions.
Assert that default Query Builder results remain integer-keyed stdClass values while custom PDO modes conservatively widen keys and row values across chained and statement-form calls.\n\nKeep cursor and lazy sequences integer-keyed, preserve Eloquent model collections through direct builder and relation forwarding, and isolate receiver mutations so later fixture assertions cannot inherit accidental state.
Describe cursor rows as mixed and preserve withoutTablePrefix() callback return types through interface-typed callers. Mark transactionLevel() impure at the connection contract that owns its mutable semantics.\n\nExpose that impurity through the DB facade mixin while excluding only the generated transactionLevel() proxy tag, preserving richer manager methods with colliding names. Regenerate the facade for the updated cursor and result-set signatures and pin the behavior with documenter and PHPStan fixtures.
Stop requiring an orphaned serve master to retain its original command line after Swoole changes the process title. Keep PPID, runtime pid file, marker pid, liveness, and process-start identity checks as the complete ownership boundary.\n\nAdd focused live-process regressions proving a renamed master is recognized only when the runtime pid file identifies it, while retaining mismatch, PID-reuse, malformed-marker, dead-process, and active-runtime protections.
Document query-scoped PDO row shapes, reset behavior, shape-owning terminals, streaming limitations, ID and cursor-pagination requirements, and the Eloquent hydration boundary using Laravel-style public guidance.\n\nRecord Capsule's deliberate omission of the ineffective connection-wide setter and direct consumers to Query Builder's safe per-query fetchUsing() API.
Capture the verified Laravel and Hypervel defects, final fetch-mode ownership rules, performance boundaries, transaction typing contract, Testbench process-identity safeguards, and user-documentation requirements.\n\nRecord the focused and four-engine regression matrix plus the full verification and review workflow so the implemented behavior remains recoverable and auditable without preserving rejected designs or review history.
Harden exception-path tests so their own assertion failures, skips, and incomplete outcomes cannot satisfy the exception being exercised. Capture controlled exceptions and assert identity outside intercepting catches, move callback observations outside those catches, and pin portable failure types and consequences where the test does not control the exact exception instance. Narrow the queue middleware catch where the expected type is fixed, keep the data-driven catch structurally non-vacuous, and document the deliberately consequence-only cache funnel catch. Add focused test-writing guidance explaining PHPUnit's exception hierarchy and requiring tests to pin escaped exceptions unless propagation is already proven by a unique later consequence. No production behavior changes.

Greptile SummaryThe PR corrects query-scoped PDO fetch behavior and fixed-shape query terminals, improves database result typing and exception-safe state restoration, and revises Testbench stale-runtime cleanup.
Confidence Score: 3/5The PR does not appear safe to merge until stale-runtime cleanup can no longer mistake a PID-reused unrelated orphan for the owned serve process and kill its process tree. The previously reported ownership defect remains: the retained PID file and coarse start identity can collide after PID reuse, and the accepted PID is then passed to recursive SIGKILL cleanup without another executable-level identity check.

If an orphaned process reuses a stale runtime PID within the same macOS one-second start-time bucket or Linux clock tick, the retained PID-file, marker, parent, and start-identity checks accept it as the owned server, causing killProcessTree() to terminate the unrelated process and its descendants.

Thanks. I traced the complete ownership predicate and am leaving this unchanged. The marker already combines the PID with the live OS process-start identity and the runtime PID file. A false match would require PID reuse with the same measured start tick or second and the same stale runtime files; no supported realistic path was found. Restoring command-line matching would reintroduce the verified defect because Swoole rewrites the live master title. Additional identity machinery would add complexity without addressing a demonstrated failure.

Pin the exact callback exception in the funnel, file-lock, and Redis-lock release tests so an acquisition timeout or another pre-callback failure cannot satisfy the test accidentally. Keep deliberately throwing closures precise, fix the database plan table rendering, and document the two valid ways tests can prove that a catch did not bypass the behavior under test.

The three lock tests now assert the exact callback exception before they verify lock release. This prevents pre-callback failures from satisfying the tests. The pipeline closure now correctly declares I also reviewed the unchanged items. The Testbench ownership checks use the live PID, orphan status, runtime PID file, and process-start identity. Command matching would conflict with Swoole process-title changes. The remaining README, facade PHPDoc, fixture, and documentation-policy decisions are consistent with the code and repository guidance. Thanks for the detailed follow-up. 🐇 ✏️ Learnings added

Summary
This PR fixes how custom PDO fetch modes flow through database connections and query builders. It also fixes stale Testbench runtime cleanup and hardens exception-path tests that could accidentally treat PHPUnit failures as success.
The database changes keep custom fetch modes scoped to row-returning queries. Methods with fixed return contracts, such as
exists(), aggregates, counts, plucks, and scalar helpers, retain those contracts regardless of the selected row mode.Context
The existing fetch-mode implementation had several correctness gaps:
selectResultSets()could not forward custom fetch arguments.transactionLevel()was treated as pure even though it reads mutable connection state.Database changes
Connection execution
fetchAll()defaults for mode-only column and class fetches.selectResultSets().fetchUsing()as the safe query-scoped API.Query Builder behavior
get(),first(), cursors, chunks, lazy iteration, and paginated result rows.nullrow from an absent row in throwing and fallback lookups where the API can represent that difference.Types and facade contracts
stdClassrows while widening custom fetch modes to their supported mixed row shapes.fetchUsing()calls.find(), result-set, andwithoutTablePrefix()contracts.transactionLevel()impure at the connection interface and expose that contract through theDBfacade without discarding richer manager signatures.Testbench cleanup
Testbench now identifies an orphaned serve runtime using the process parent, runtime PID file, marker PID, process liveness, and process start identity. It no longer requires the Swoole master to keep its original command line after Swoole changes the process title.
This keeps the PID-reuse and ownership safeguards while allowing interrupted test runs to clean up the server tree they created.
Test correctness
Several exception-path tests caught broad exception types around their own assertions. In those cases, an assertion failure, skipped test, or incomplete marker could satisfy the catch and make the test pass.
The affected tests now capture and pin the expected exception outside the intercepting catch, then assert callback observations and restored state. The testing guide records this rule so future exception-path tests do not repeat the pattern. No production behavior changes are included in this part.
Documentation
The query documentation now explains:
Compatibility and performance
The default query path keeps the same SQL, bindings, statement preparation, and result processing. The changes add no queries, network calls, connection checkouts, result buffering, worker-lifetime state, or caches.
Laravel-style query APIs and named arguments remain intact. The only deliberate public omission is Capsule's ineffective connection-wide fetch setter; query-scoped
fetchUsing()is the supported replacement.Testing
