From bde127c6c72b55e116caddb4effc5c24fbc2ac32 Mon Sep 17 00:00:00 2001 From: Elior Erez Date: Tue, 23 Jun 2026 19:48:41 -0400 Subject: [PATCH 1/2] Add `graphify ci-select` subcommand for graph-informed CI test selection Uses the graphify knowledge graph to determine which CI tests to run for a given set of code changes. BFS traversal up to N hops from changed files, then maps reachable nodes to CI job names via a test-jobs.yaml mapping. Features: - Parse git diffs or accept explicit file lists - BFS traversal with configurable depth (default 3 hops) - Cross-repo impact detection via source_file prefixes - Confidence tiers: >=0.8 use as-is, 0.5-0.8 log, <0.5 full suite fallback - Job categorization: must_run (3+ pattern matches), should_run (1-2), skip (0) - Structured JSON output with reasoning and graph paths - Sub-second performance on 51K-node graphs --- graphify/__main__.py | 8 + graphify/ci_select.py | 600 ++++++++++++++++++++++++++++++++++++++++ graphify/cli.py | 4 + tests/test_ci_select.py | 351 +++++++++++++++++++++++ 4 files changed, 963 insertions(+) create mode 100644 graphify/ci_select.py create mode 100644 tests/test_ci_select.py diff --git a/graphify/__main__.py b/graphify/__main__.py index 924ae986d3..cf1a8d0d48 100644 --- a/graphify/__main__.py +++ b/graphify/__main__.py @@ -623,6 +623,14 @@ def _run_cli() -> None: print(" global remove remove a repo's nodes from the global graph") print(" global list list repos in the global graph") print(" global path print path to the global graph file") + print(" ci-select graph-informed CI test selection from a diff") + print(" --repo repository name (required)") + print(" --diff-cmd shell command to produce a diff (e.g. 'git diff origin/main...HEAD')") + print(" --diff read diff from file or stdin") + print(" --files comma-separated changed file paths") + print(" --graph path to graph.json (default graphify-out/graph.json)") + print(" --test-jobs path to test-jobs.yaml mapping (auto-detected if omitted)") + print(" --depth N BFS traversal depth (default 3)") print(" benchmark [graph.json] measure token reduction vs naive full-corpus approach") print(" export callflow-html emit Mermaid-based architecture/call-flow HTML") print(" hook install install post-commit/post-checkout git hooks (all platforms)") diff --git a/graphify/ci_select.py b/graphify/ci_select.py new file mode 100644 index 0000000000..6df5c9296b --- /dev/null +++ b/graphify/ci_select.py @@ -0,0 +1,600 @@ +"""graphify ci-select: Graph-informed CI test selection. + +Uses the graphify knowledge graph to determine which CI tests to run +for a given set of code changes.
