ONE vscode Developer's Certificate of Origin - Samsung/ONE-vscode GitHub Wiki

The ONE-vscode project uses the signed-off-by language and process, to give us a clear chain of trust for every patch received.

By making a contribution to this project, I certify that:

(a) The contribution was created in whole or in part by me and I have the right to submit it under the open source license indicated in the file; or

(b) The contribution is based upon previous work that, to the best of my knowledge, is covered under an appropriate open source license and I have the right under that license to submit that work with modifications, whether created in whole or in part by me, under the same open source license (unless I am permitted to submit under a different license), as indicated in the file; or

(c) The contribution was provided directly to me by some other person who certified (a), (b) or (c) and I have not modified it.

(d) I understand and agree that this project and the contribution are public and that a record of the contribution (including all personal information I submit with it, including my sign-off) is maintained indefinitely and may be redistributed consistent with this project, under the same open source license.

We have the same requirements for using the signed-off-by process as the Linux kernel. In short, you need to include a signed-off-by tag in every patch:

"Signed-off-by:" this is a developer's certification that he or she has the right to submit the patch for inclusion into the project. It is an agreement to the Developer's Certificate of Origin (above). Code without a proper signoff cannot be merged into the mainline.

You should use your real name and email address in the format below:

ONE-vscode-DCO-1.0-Signed-off-by: Random O Developer [email protected]

It is easy to forget adding DCO end of every commit message. Fortunately there is a nice way to do it automatically. Once you've cloned the repository into your local machine, you can add prepare-commit-msg hook in .git/hooks directory like this:

#!/usr/bin/env python3

import sys

commit_msg_filepath = sys.argv[1]

with open(commit_msg_filepath, "r+") as f:
	content = f.read()
	if "Signed-off-by:" not in content:
		f.seek(0, 0)
		f.write("%s\n\nONE-vscode-DCO-1.0-Signed-off-by: <Your Name> <<Your Email>>" % content)

or, if you are a bash user:

#!/usr/bin/env bash

COMMIT_MSG_FILE=$1
NAME=$(git config user.name)
EMAIL=$(git config user.email)

if [[ $(git log --oneline HEAD ^upstream/main | wc -l) -gt 0 ]]; then
  exit 0
fi

if ! grep "Signed-off-by:" ${COMMIT_MSG_FILE}; then
  echo -e "\n\nONE-vscode-DCO-1.0-Signed-off-by: $NAME <$EMAIL>" >> ${COMMIT_MSG_FILE}
fi
