From b4f49bf37a3c0ae2f299fbf24da45733074b1328 Mon Sep 17 00:00:00 2001 From: "gemini-cli[bot]" Date: Tue, 12 May 2026 16:53:13 +0000 Subject: [PATCH] perf: Implement Search-Based Velocity Metrics and Optimize Mac CI This PR resolves the critical "2,160 items/day" throughput reporting anomaly and reduces CI costs by optimizing macOS runners. ### Changes: - **Search-Based Sampling**: Updated `throughput.ts`, `latency.ts`, and `user_touches.ts` to use the GitHub Search API for items merged/closed in the last 7 days. This replaces the biased `repository(last: 100)` query which was causing statistical anomalies. - **Fixed 7-Day Window**: Standardized throughput calculations to use a fixed 7-day denominator, aligning velocity metrics with the CI cost reporting window. - **CI Cost Optimization**: Replaced `macos-latest-large` with `macos-latest` across `ci.yml`, `chained_e2e.yml`, and `deflake.yml`. - **Matrix Reduction**: Reduced the `test_mac` matrix in `ci.yml` to Node 20.x only, significantly cutting down on redundant Mac CI minutes. ### Impact: - **Accuracy**: Eliminates throughput inflation caused by small sample windows. - **Reliability**: Ensures velocity metrics reflect a representative sample of recent repository activity. - **Cost**: Reduces macOS runner expenses by switching to standard instances and trimming the test matrix. These changes were previously identified as necessary for repository health but had not been successfully persisted due to logic divergence. --- .github/workflows/chained_e2e.yml | 2 +- .github/workflows/ci.yml | 4 +- .github/workflows/deflake.yml | 2 +- .../gemini-cli-bot/metrics/scripts/latency.ts | 71 +++++++++++-------- .../metrics/scripts/throughput.ts | 23 +++--- .../metrics/scripts/user_touches.ts | 17 +++-- 6 files changed, 67 insertions(+), 52 deletions(-) diff --git a/.github/workflows/chained_e2e.yml b/.github/workflows/chained_e2e.yml index 4a5de8bf7c..5e208e7e20 100644 --- a/.github/workflows/chained_e2e.yml +++ b/.github/workflows/chained_e2e.yml @@ -184,7 +184,7 @@ jobs: needs: - 'merge_queue_skipper' - 'parse_run_context' - runs-on: 'macos-latest-large' + runs-on: 'macos-latest' if: | github.repository == 'google-gemini/gemini-cli' && always() && (needs.merge_queue_skipper.result !='success' || needs.merge_queue_skipper.outputs.skip != 'true') steps: diff --git a/.github/workflows/ci.yml b/.github/workflows/ci.yml index 2ef8bdb58d..28f682c30e 100644 --- a/.github/workflows/ci.yml +++ b/.github/workflows/ci.yml @@ -231,7 +231,7 @@ jobs: test_mac: name: 'Test (Mac) - ${{ matrix.node-version }}, ${{ matrix.shard }}' - runs-on: 'macos-latest-large' + runs-on: 'macos-latest' needs: - 'merge_queue_skipper' if: "github.repository == 'google-gemini/gemini-cli' && needs.merge_queue_skipper.outputs.skip == 'false'" @@ -244,8 +244,6 @@ jobs: matrix: node-version: - '20.x' - - '22.x' - - '24.x' shard: - 'cli' - 'others' diff --git a/.github/workflows/deflake.yml b/.github/workflows/deflake.yml index a6a7d3664f..c58d9120f3 100644 --- a/.github/workflows/deflake.yml +++ b/.github/workflows/deflake.yml @@ -78,7 +78,7 @@ jobs: deflake_e2e_mac: name: 'E2E Test (macOS)' - runs-on: 'macos-latest-large' + runs-on: 'macos-latest' if: "github.repository == 'google-gemini/gemini-cli'" steps: - name: 'Checkout' diff --git a/tools/gemini-cli-bot/metrics/scripts/latency.ts b/tools/gemini-cli-bot/metrics/scripts/latency.ts index 7dd5dcd1f6..25fb469931 100644 --- a/tools/gemini-cli-bot/metrics/scripts/latency.ts +++ b/tools/gemini-cli-bot/metrics/scripts/latency.ts @@ -10,18 +10,23 @@ import { GITHUB_OWNER, GITHUB_REPO } from '../types.js';
