…ne-10 The clientconfig.arguments for `memtier_benchmark-5Mkeys-string-mget-1KiB-5keys-pipeline-10` was missing the `--pipeline 10` flag (sibling specs at other value sizes — 100B, 512B — all carry it). Without the flag, memtier_benchmark defaulted to pipeline=1, so the test was not exercising the pipelined-MGET path its name advertises. This made the run produced for redis/redis#14907 misleading: the −12.6 % "regression" on this spec was at effective pipeline=1, while every other pipeline-10 MGET sibling on the same matrix showed +1–7 % wins under proper pipelining. Bump to 0.3.18.
The branch bumped pyproject 0.3.17->0.3.18, which now conflicts with main (already at 0.3.23). Restore pyproject.toml to main so only the test-suite fix (adding the missing --pipeline 10 to the pipeline-10 mget spec) remains.

Summary
memtier_benchmark-5Mkeys-string-mget-1KiB-5keys-pipeline-10.ymlwas missing--pipeline 10in itsclientconfig.arguments. Every sibling pipeline-10 MGET spec on the same matrix (100B, 512B, 1KiB-* with various key counts) ships the flag — this one was the only outlier.Without the flag, memtier_benchmark defaults to pipeline=1, so the test was running un-pipelined despite the name advertising pipeline-10.
Why it matters
A recent regression-investigation run on redis/redis#14907 (per-IO-thread stat counters) flagged
mget-1KiB-5keys-pipeline-10as the only σ-confirmed regression in the io-threads=8 string suite (−12.6 %). Every other pipeline-10 MGET sibling on the same axis (+1.5 % to +6.5 %) moved the opposite direction, which didn't fit any false-sharing-fix mechanism. Spec inspection showed the--pipeline 10was missing — the regression was being measured at effective pipeline=1.Changes
--pipeline 10to theclientconfig.argumentsline.Test plan
mget-1KiB-5keys-pipeline-10against PR head + unstable baseline onoss-standalone-08-io-threads; confirm both numbers shift up to the pipelined operating point and the PR delta no longer shows the spurious −12 %.Note
Low Risk
Benchmark-spec correction and packaging metadata only; no runtime application logic changes.
Overview
Aligns
memtier_benchmark-5Mkeys-string-mget-1KiB-5keys-pipeline-10with other pipeline-10 MGET specs by adding--pipeline 10toclientconfig.arguments. Without it, memtier ran at pipeline=1, so benchmark deltas (e.g. spurious regressions on io-threads suites) did not match the intended pipelined workload.pyproject.tomlbumps the package to 0.3.23, explicitly **include**sfiles-to-groups.jsonandcore-specs.jsonin sdist/wheel, and raisespoetry_coreto >=1.5.0 so dict-formincludewithformatis honored at build time.Reviewed by Cursor Bugbot for commit 53d2f03.
