Summary

  • Prefer the current seekdb Python binding for embedded mode.
  • Fall back to legacy pylibseekdb so existing installations remain compatible.
  • Keep the existing backend selection and instance lifecycle unchanged after the binding is loaded.

Scope cleanup

This PR now contains product code only. The latest cleanup removed the embedded full-text tests, source-wheel CI workflow, wheel-manifest helpers, dependency/model CI changes, test documentation, and all unit/integration test modifications from this repository.

The real 4016 regressions and their Linux/macOS execution are owned by the separate internal SeekDB regression MR: obqa/seekdb_test!70. That MR runs the current PySeekDB source against the pipeline-built native wheel and keeps the actual database workload and evidence collection outside this product PR.

Validation

  • Existing tests/unit_tests/test_embedded_client_lifecycle.py: 7 passed without modifying the test file.
  • Python bytecode compilation passed for src/pyseekdb/client.
  • git diff --check passed.

No assertions, skips, or existing tests were weakened. Full source-built wheel and real-database validation remains a merge gate in seekdb_test!70; it is not represented as completed by the local checks above.

Summary by CodeRabbit

  • Bug Fixes

    • Improved embedded-client compatibility by preferring the current seekdb binding while retaining support for the legacy pylibseekdb binding.
    • Updated embedded-client availability messages and documentation to reflect supported bindings.
  • Tests

    • Added integration coverage for embedded full-text search stability during sustained querying, ingestion, and maintenance operations.
    • Added diagnostic evidence collection and validation for failures in embedded full-text scenarios.
  • Chores

    • Improved automated validation of embedded builds and integration test environments.

📝 Walkthrough

Walkthrough

The embedded client now prefers seekdb and falls back to pylibseekdb. New full-text stability scenarios collect diagnostics and validate reports. CI now builds, verifies, installs, caches, and records provenance for a pinned embedded wheel.

Changes

Embedded runtime validation

Layer / File(s) Summary
Embedded binding compatibility
src/pyseekdb/client/__init__.py, src/pyseekdb/client/client_seekdb_embedded.py
The client imports seekdb first and falls back to pylibseekdb. Documentation and runtime errors use generic embedded-binding terminology.
Embedded full-text stability harness
tests/integration_tests/embedded_fulltext_support.py, tests/integration_tests/test_embedded_fulltext_stability.py
The harness adds first-pass and scan-freeze scenarios, bounded error and log capture, JSON report validation, and isolated subprocess regression coverage.
Pinned embedded wheel build
.github/embedded-source.json, .github/scripts/*
The build scripts check pinned source revisions, build the embedded engine and bindings, and record wheel and binary provenance.
CI embedded wheel integration
.github/workflows/ci.yml
The embedded integration job restores or builds the verified wheel, installs it, uploads provenance, and uses uv run --no-sync for testing.

Priority: ⬇️ Low

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

Change: Bug fix

Merge Risk: 🟡 Moderate · up to 458e5

The PR changes embedded runtime selection and CI wheel validation, but examples may exercise a different package and diagnostics may misidentify or lose failure context. Merge readiness is moderate until these paths are corrected or explicitly accepted.

Final downstream validation evidence for head 8bdee2a6b4c3a65ac2f3a8cb81eadffae52ec6bf:

  • Internal GitLab Pipeline 268704 / child 268706 / Job 1841969 completed successfully on Linux with the source-built SeekDB validation wheel.
  • Runtime identity was distribution=seekdb (seekdb-1.4.0.dev1).
  • Unit: 623 passed, 221 skipped.
  • Neutral integration: 3 passed, 39 skipped, 1254 deselected.
  • Embedded integration: 119 passed, 298 skipped, 878 deselected, 1 xpassed.
  • Both required regression cases ran (not skipped/xfail) and passed: test_embedded_fulltext_stability[first-pass] and test_embedded_fulltext_stability[scan-freeze]. No 4016 appeared in the job trace.
  • Sparse, default dense, and ONNX model preparation completed, then the full offline pytest suite exited normally.

The earlier macOS validation (Pipeline 268527 / child 268528) also passed both FTS scenarios without 4016. Its remaining test_collection_fork::test_fork_success[embedded] 4012 timeout is a separate product issue and was not retried or hidden. This PR remains Draft while that product work stays separately tracked.

Do not hide initialization failures from the preferred binding.

importlib.import_module(distribution) can raise ModuleNotFoundError for a dependency of an installed seekdb. The current except ImportError treats that failure as if seekdb were absent, then selects pylibseekdb or reports that no binding exists. Catch only a missing top-level distribution and re-raise other import failures.

-        except ImportError:
-            pass
+        except ModuleNotFoundError as exc:
+            if exc.name != distribution:
+                raise

Update the fallback test to raise ModuleNotFoundError(name="seekdb") instead of the current generic ImportError.

Handle log rotation during file discovery.

capture_logs calls p.stat() while sorting, then calls path.stat() and path.open() without handling FileNotFoundError. If a seekdb.log* file disappears between these operations, the exception escapes. Recorder.error calls capture_logs directly for the first error, so immediate failure-context collection can abort.

Handle FileNotFoundError per path, continue scanning, and record the skipped path with a not-found status in the inventory. Build sortable entries with per-path stat handling instead of using an unguarded sort key.

@hnwyllmm This PR is ready for maintainer review and merge.

Changes are intentionally limited to product code:

  • prefer the current seekdb embedded binding;
  • fall back to legacy pylibseekdb for compatibility;
  • keep backend selection and embedded instance lifecycle unchanged after loading the binding.

All GitHub Actions checks are passing. Existing embedded lifecycle tests pass (7/7), and the real full-text/4016 regression remains in obqa/seekdb_test!70 rather than this product PR.

Record the binding selected by _load_embedded_runtime().

find_spec("seekdb") checks discoverability, not import success. If importing seekdb raises ImportError, _load_embedded_runtime() selects pylibseekdb, but this code still labels the report as seekdb and reads the seekdb version. Populate these fields after make_client() from the loader’s selected distribution, or expose that distribution through SeekdbEmbeddedClient.
