Code Review

This pull request adds the SPDX-FileCopyrightText to many files in the repository. The changes are mostly correct and consistent with the PR's goal. I've found one minor issue in tools/check_pickle_imports.py where the SPDX-License-Identifier was duplicated. Please see my comment for the suggested fix.

👋 Hi! Thank you for contributing to the vLLM project.

💬 Join our developer Slack at https://slack.vllm.ai to discuss your PR in #pr-reviews, coordinate on features in #feat- channels, or join special interest groups in #sig- channels.

Just a reminder: PRs would not trigger full CI run by default. Instead, it would only run fastcheck CI which starts running only a small and essential subset of CI tests to quickly catch errors. You can run other CI tests on top of those by going to your fastcheck build on Buildkite UI (linked in the PR checks section) and unblock them. If you do not have permission to unblock, ping simon-mo or khluu to add you in our Buildkite org.

Once the PR is approved and ready to go, your PR reviewer(s) can run CI to test the changes comprehensively before merging.

To run CI, PR reviewers can either: Add ready label to the PR or enable auto-merge.

Thanks, I wonder why pre-commit doesn't add them automatically? Can you fix it in this PR?

Thanks, I wonder why pre-commit doesn't add them automatically?

It's because we only check SPDX_HEADER_PREFIX but not check the existance of SPDX-FileCopyrightText, so file only has SPDX-License-Identifier header can still pass the check:

vllm/tools/check_spdx_header.py

Lines 6 to 21 in 7f03671

	SPDX_HEADER = (
	"# SPDX-License-Identifier: Apache-2.0\n"
	"# SPDX-FileCopyrightText: Copyright contributors to the vLLM project")
	SPDX_HEADER_PREFIX = "# SPDX-License-Identifier:"
	def check_spdx_header(file_path):
	with open(file_path, encoding='UTF-8') as file:
	lines = file.readlines()
	if not lines:
	# Empty file like __init__.py
	return True
	for line in lines:
	if line.strip().startswith(SPDX_HEADER_PREFIX):
	return True
	return False
