Reporting an Issue & Feature Suggestions

You can find a list of all outstanding issues and feature requests on our Github issue tracker. Before creating a new issue or feature suggestion, ensure that:

  • The issue or feature request hasn't been addressed in a newer version of mpiFileUtils.
  • That the issue or feature request doesn't already exist in the issue tracker.

If the issue or feature request already exists, please provide additional information if possible.

When creating a new issue, please provide at least the following information:

  • mpiFileUtils Version
  • Linux Distribution & Version
  • Steps to reproduce the problem

Pull Requests

If you would like us to consider a change to mpiFileUtils, feel free to submit a pull request. Your pull request must meet the following criteria before it can be merged.

  • Your pull request must be based on the current master branch and apply without conflicts.
  • Please try to limit pull requests to a single commit which resolves one issue.
  • Make sure your commit messages have a Signed-off-by line. See Contributor's Declaration for more information.
  • For large pull requests, consider structuring your changes as a stack of logically independent patches which build on each other. This makes large changes easier to review and approve which speeds up the merging process.
  • Try to keep pull requests simple. Simple code with comments is much easier to review and approve.
  • Test cases should be provided when appropriate.
  • Your pull request must pass automated testing.
  • All proposed changes must be approved by an mpiFileUtils project member.

Contributor's Declaration

mpiFileUtils has adopted the signed-off-by process as described in Section 11 of the Linux kernel document on Submitting Patches. Each proposed contribution to the mpiFileUtils code base must include the text "Signed-off-by:" followed by the contributor's name and email address. This is the developer's certification that they have the right to submit the patch for inclusion into the code base and indicates agreement to the Developer's Certificate of Origin:

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

  1. 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
  2. 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
  3. The contribution was provided directly to me by some other person who certified (1), (2) or (3) and I have not modified it.
  4. 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 or the open source license(s) involved."

After reading and agreeing to the Contributor's Declaration, include your Signed-off-by text like the following as the last line in your commit message:

Proposed contributions failing to include a "Signed-off-by:" certification will not be accepted into mpiFileUtils. The maintainers reserve the right to revert any commit made without the required certification.
