Bug report and pull requests

Vineyard is hosted on Github, and use Github issues as the bug tracker. You can file an issue when you find anything that is expected to work with vineyard but it doesn’t.

Before creating a new bug entry, we recommend you first search among existing vineyard bugs to see if it has already been resolved.

When creating a new bug entry, please provide necessary information of your problem in the description, such as operating system version, vineyard version, and other system configurations to help us diagnose the problem.

We also welcome any help on vineyard from the community, including but not limited to fixing bugs and adding new features. Our project vineyard has enabled DCO thus you will be asked to sign-off your commits that are included in your pull requests. Git has a -s command line option that can sign-off your commit automatically:

git commit -s -m 'This is my commit message'

Code format

Vineyard follows the Google C++ Style Guide. When submitting patches to vineyard, please format your code with clang-format by the Makefile command make vineyard_clformat, and make sure your code doesn’t break the cpplint convention using the CMakefile command make vineyard_cpplint.

Open a pull request

When opening issues or submitting pull requests, we’ll ask you to prefix the pull request title with the issue number and the kind of patch (BUGFIX or FEATURE) in brackets, for example, [BUGFIX-1234] Fix crash in sealing vector to vineyard or [FEATURE-2345] Support seamless operability with PyTorch’s tensors.

Git workflow for newcomers

You generally do NOT need to rebase your pull requests unless there are merge conflicts with the main. When Github complaining that “Can’t automatically merge” on your pull request, you’ll be asked to rebase your pull request on top of the latest main branch, using the following commands:

  • First rebasing to the most recent main:

git remote add upstream https://github.com/v6d-io/v6d.git
git fetch upstream
git rebase upstream/main
  • Then git may show you some conflicts when it cannot merge, say conflict.cpp, you need - Manually modify the file to resolve the conflicts - After resolved, mark it as resolved by

git add conflict.cpp
  • Then you can continue rebasing by

git rebase --continue
  • Finally push to your fork, then the pull request will be got updated:

git push --force
