🌐 Web query:
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.

LGTM. ASAN Integration tests failed but does not seem to be related to the changes. Try rebasing with the latest main branch and it should be solved.

Hi @bandalgomsu 👋 — flagging this as a P1 launch blocker for valkey-search 1.3 RC1. We're cutting the release branch the morning of Sept 14 (RC1 lands Sept 15), so all P1s need to be merged before then. First-pass reviewer: @boda26 — if your first-pass review is already done, please ignore this message; otherwise, please prioritize getting this PR reviewed. Second-pass reviewer: @yairgott — please take a look/followup with the final review and merge once everything looks good. If anything is blocking merge (open changes, CI, design questions), drop a note here so we can unblock quickly. Board: #1346. Thanks so much! 🙏 |

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