What does the PR do?

Aligns this repository with the org-wide setup consolidated in triton-inference-server/.github:

  • .pre-commit-config.yaml: shared baseline hooks, conventional-commit message validation (commit-msg stage), and the centralized add-license hook from the org .github repository (rev: v1.4.3 — excludes .github/ templates, never rewrites LICENSE files).
  • Pre-commit CI runs only on files modified by the PR.
  • Caller stub for the org-wide reusable conventional-pr workflow (@v1.4.3): validates the PR title against Conventional Commits (hard gate — it becomes the squash-merge commit), derives one human-readable label per distinct type found in the title and all conforming commit subjects (e.g. ci:CI/CD, feat:feature, fix:fix), enforces org-wide label colors/descriptions, detects cherry-picks, and fails if no type is derivable and no type label is assigned.
  • No per-repo templates: PR templates and issue routing are inherited from the org-wide defaults in triton-inference-server/.github (issues route to the server repository).

Repo-specific: keeps the ^src/grpc_generated exclude and the mypy hook.

Depends on triton-inference-server/.github#5 (pinned tags current: v1.4.3 — already exist, CI is green).

Pros / Cons

Pros

  • Single home (org .github repo) for hooks, templates, issue routing, and the PR-title workflow — one change propagates everywhere.
  • Repos carry only a config file and two small workflow stubs; no template copies to drift.
  • Commit/PR title format enforced both locally (commit-msg hook) and in CI (reusable workflow), with automatic type labels.
  • License hooks never modify LICENSE files.

Cons / risks

  • Version-pinned dependency on the org .github repository (tags are write-once; changes ship as a new tag + rev bump).
  • Template inheritance requires the org .github repository to remain public.

Test plan

  • pre-commit validate-config passes; pre-commit run --files <PR diff> passes locally with the centralized hooks pinned to the .github branch SHA.
  • After .github#5 merges and v1.4.3 exists: the conventional-pr check validates this PR's own title and applies the ci label.
  • No LICENSE file content is changed by this PR.

Caveats

  • None beyond the merge-order note above.

Checklist

  • PR title follows <commit_type>: <Title> (conventional commit)
  • I ran pre-commit locally on all files changed by this PR and it passes
  • Copyright header is correct on all changed files
  • External contributors: I have read the Contribution guidelines and signed the Contributor License Agreement

Adopt the shared pre-commit baseline: two-line SPDX header, conventional
commit message validation (commit-msg stage), and the centralized
add-license / add-spdx-license hooks from developer_tools v0.2.0.
Run pre-commit CI only on files modified by the PR, and roll out the
standard issue templates and the simplified single PR template.

Identical to python_backend#449. Quick LGTM.

Greptile Summary

This PR aligns the repository's CI infrastructure with the org-wide standards consolidated in triton-inference-server/.github, replacing per-repo copies with thin caller stubs that delegate to pinned reusable workflows and hooks.

  • Adds conventional-pr.yml: a thin caller that routes same-repo PRs through the safe pull_request event and fork PRs through pull_request_target (labeling only, no code checkout), both delegating to the org reusable workflow at v1.4.3.
  • Rewrites pre-commit.yml: drops the old pre-commit/action wrapper in favour of a direct invocation with null-delimited path handling (-z/-0), deleted-file filtering (--diff-filter=d), and a ~/.cache/pre-commit cache keyed on the config hash.
  • Updates .pre-commit-config.yaml: adds default_install_hook_types, a commit-msg-stage conventional-pre-commit hook, fixes flake8 arg quoting, and migrates add-license from developer_tools@v0.1.0 to triton-inference-server/.github@v1.4.3.

Confidence Score: 5/5

Safe to merge — all three files contain CI/tooling configuration only; no production code is touched.

The fork-PR routing conditional in conventional-pr.yml is logically correct, the pull_request_target path is protected by an explicit if guard, and the pre-commit workflow HEAD^1 HEAD diff works correctly with GitHub Actions merge-commit checkout. The contents: read permission is present in both workflows.

No files require special attention.

Important Files Changed

Filename Overview
.github/workflows/conventional-pr.yml New thin-caller workflow; routes same-repo PRs via pull_request and fork PRs via pull_request_target with correct conditional, appropriate permissions, and pinned reusable workflow at v1.4.3
.github/workflows/pre-commit.yml Improved pre-commit runner: adds contents:read permission, pre-commit environment caching, null-delimited path handling for spaces, and --diff-filter=d to skip deleted files
.pre-commit-config.yaml Adds default_install_hook_types, conventional-pre-commit commit-msg hook, fixes flake8 args quoting/spacing, and migrates add-license hook from developer_tools to the org .github repo at v1.4.3

P1 Version tag mismatch with PR description and test plan

The workflow (and .pre-commit-config.yaml) pin to v1.4.2, but the PR description and test plan consistently say v1.4.1 ("pinned tags current: v1.4.1 — already exist, CI is green" / "After .github#5 merges and v1.4.1 exists"). If v1.4.2 is the intended tag and it exists, this is a stale description — update the prose. If v1.4.2 has not yet been published to the org .github repo, both the workflow and the pre-commit hook will fail at runtime when the tag cannot be resolved.

Fixed - documentation drift: the descriptions have been refreshed to the current pinned tag v1.4.3 (they lagged behind the tag revisions; the tag exists and CI is green fleet-wide).

Comment thread .github/workflows/conventional-pr.yml Outdated
- conventional-pr stub: dual pull_request/pull_request_target triggers
  so fork PRs from external contributors get labeled too (the reusable
  workflow never checks out PR code); explicit contents:read; pinned
  v1.4.3.
- pre-commit workflow: robust modified-files runner (null-delimited
  paths, deletion-only PRs handled, deleted paths filtered, no
  undocumented -r flag, cache keyed on config hash).
- flake8 args quoted correctly (the flow-scalar form split at commas
  and silently reduced the select list).
- hooks pinned to .github v1.4.3.

Closing: the team is moving away from centralized org-level configuration in favor of per-repository self-contained setups (see triton-inference-server/server#8897 for the first decentralized implementation). Branch retained for reference. TRI-1100
