Phase 1 — PHP import integrity

Keeps the existing one-call import workflow and direct importer behavior; no dependencies, caller configuration, schema additions, or recovery/versioning layer.

Changes

  • Preserve binary64 cases and affected numeric metadata using the existing shared encoder with locale/configuration-independent 17-digit formatting.
  • Temporarily use PDO exception mode during imports, restoring the caller's mode on success/failure instead of silently accepting failed SQL writes.
  • Reject caller-owned transactions before mutation.
  • Finalize SQLite/PostgreSQL success journals inside the importer's native transaction; preserve MySQL/MariaDB/Dolt attempt-owned compensation.

Evidence

  • RED commit 2cf4ab7: 13 reproduced failures; 2 PostgreSQL integration cases skipped locally.
  • GREEN commit e5d30bb: composer check and the staged-tree pre-commit checks pass: 544 tests, 3,274 assertions, 82 environment-dependent skips.
  • Local independent subagent review found an encoding corner case; fixed in the shared helper and covered at default and nondefault serialize_precision. Full-diff re-review: No findings.
  • Both push and pull-request CI runs passed all 20 jobs: PHP 8.4/8.5 plus PostgreSQL 17.10/18.4, MySQL 8.4.11/9.7.2, MariaDB 11.4.12/11.8.8/12.3.2, and Dolt 2.2.2/2.2.3 integration matrices. Local mock results are not claimed as live-server evidence.
  • Local checkout has CRLF hook shebangs; ran the tracked LF pre-commit script explicitly against the staged archive before committing. No hook/config changes included.

Scope and next phase

This is phase 1 of the approved correctness/performance/simplification plan. Next: Python in-place metadata integrity (shared value-label ownership and referenced-variable deletion), in its own PR.

Final review

  • Latest-head @codex review completed for e5d30bb: no findings, confirmed by the bot’s comment and 👍 reaction.
  • CodeRabbit's two comments were independently adjudicated: explicit exception chaining duplicates PHP's native finally behavior; extra cleanup connections/persistent recovery are outside the supplied-PDO contract and cannot safely replace fail-closed rollback handling. Runtime evidence and rationale are recorded in the review threads.
  • Residual limitation: if the MySQL-family connection/rollback itself fails, an attempt-owned physical table can require manual cleanup. The importer does not issue potentially implicit-committing DROP on an uncertain transaction.

Please do not merge automatically. Phase 1 is ready for handoff; the overall plan is not complete.

📝 Walkthrough

Walkthrough

The change preserves Binary64 numeric values, strengthens PDO transaction handling, and coordinates import finalization with transaction boundaries. Tests cover precision preservation, caller-owned transactions, error-mode restoration, rollback behavior, and finalization failures.

Changes

Import integrity changes

Layer / File(s) Summary
Binary64 persistence
src/Core/Binary64.php, src/Sql/NormativeCatalog.php, src/Sql/SqliteV3MetadataImporter.php, src/Sql/SqliteWideTableImporter.php, tests/Spss/SpssAdapterTest.php, tests/Sql/*WideTableImporterTest.php
Finite numeric values use 17-digit hexadecimal encoding. Multiple-response counted values and SQLite numeric cells preserve the encoded representation. Tests cover binary64 values and string-form counted values.
Transactional SQL import safety
src/Sql/MySqlWideTableImporter.php, src/Sql/PostgreSqlWideTableImporter.php, src/Sql/SqliteWideTableImporter.php, tests/Sql/*WideTableImporterTest.php
Import entry points reject caller-owned transactions, use PDO exception mode during operations, check transaction results, restore the previous error mode, and surface rollback failures.
Adapter finalization flow
src/Spss/SpssAdapter.php, tests/Spss/SpssAdapterTest.php, tests/Integration/PostgreSqlSpssRoundTripTest.php
Finalization runs inside the importer transaction for PostgreSQL and SQLite. MySQL finalization runs after importer completion. Tests verify failed finalization rollback, journaling, unchanged prior state, and error-mode restoration.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to e5d30

Rare database failure paths can leave orphaned tables or record the wrong import failure. These integrity and diagnostic issues should be addressed before merge.

In `@src/Sql/MySqlWideTableImporter.php`:
- Around line 104-109: The MySqlWideTableImporter::import() failure path must
clean up the physical table even when rollback fails or throws, without using
the active $pdo transaction. Add a separate known-cleanup connection or durable
recovery mechanism that invokes dropPhysicalTable() after rollback handling
while preserving rollback error propagation and ensuring SpssAdapter still
receives the definition for compensateFailure().
- Around line 115-117: Update all five PDO::ATTR_ERRMODE restoration finally
blocks in MySqlWideTableImporter::import(), SqliteWideTableImporter::import(),
both PostgreSqlWideTableImporter methods, and SpssAdapter::import() to retain
the primary operation exception; when setAttribute() fails, throw the
restoration RuntimeException with the captured primary exception as its previous
cause, while preserving normal restoration behavior when no primary exception
exists.
