Suggested reviewers: Merge Risk: 🔵 Low · up to The change improves zero-length vector save/restore coverage, but one test assertion may fail to validate every returned response element, allowing a regression to pass unnoticed.

Ubuntu 24.04 Noble default python3 version python3.12
💡 Result:
Yes, Python 3.12 is the default Python 3 version for Ubuntu 24.04 LTS (Noble Numbat) [1][2][3]. The system interpreter, accessible via the python3 command, is based on the Python 3.12 series [4][5][6]. Official documentation and release notes confirm that Python 3.12 is the default version included with the distribution [2][3]. As is standard for Ubuntu, this system-provided Python is used by various system tools (such as apt and cloud-init) [5][6][7]; it is recommended to use virtual environments or tools like pipx to manage project-specific dependencies to avoid conflicts with system-managed packages [5][6][7].

Use strict=True in both zip() calls.
The integration environment uses Python 3.12. Without strict=True, an odd-length response can be silently truncated.

| Filename | Overview |
|---|---|
| src/index_schema.cc | Replaces the zero-length-string rejection with a null-pointer guard so valid empty keys enter the normal mutation pipeline. |
| src/indexes/vector_base.cc | Removes empty-key restrictions from vector metadata tracking, modification, and removal while retaining normal map and internal-ID handling. |
| integration/test_saverestore.py | Adds Flat and HNSW persistence coverage for a zero-length vector key, including pre-save indexing waits and post-restart verification. |
| integration/test_fulltext.py | Adds backfill and live-update coverage for a zero-length hash key in a text index. |
| integration/test_non_vector.py | Adds backfill and live-update coverage for a zero-length JSON key with tag and numeric fields. |
| integration/test_vss_basic.py | Adds Flat and HNSW backfill coverage proving KNN responses preserve a zero-length key. |

Reapplies #1171 and stabilizes zero-length vector save/restore coverage.
Wait for initial backfill and KNN indexing to complete before saving.
