openSUSE Salt Packaging

This repository tracks upstream salt and the patches for the openSUSE salt package.

See here for working with remote git repositories.

Branches

  • develop - upstream development
  • 2015.8 - upstream branch for 2015.8.X bugfixes
  • openSUSE-2015.8.3 - openSUSE branch for the openSUSE salt package

The openSUSE-2015.8.3 branch is based on the v2015.8.3 upstream tag. Commits on the openSUSE-2015.8.3 branch apply cleanly on the salt-2015.8.3.tar.gz release tarball.

Workflow

Policies

  • ⚠️ Always try to keep patches merged to the upstream, if your patch is related to the source. If upstream does not likes the fix, try to find a compromise and try having no patches that aren't upstream.
  • ⚠️ Always open Pull Requests for your fixes upstream and never on openSUSE branch. The openSUSE branch exists merely for the accepted-ready commits that were already discussed.
  • Keep patches local as long as they do not need to be posted upstream and are package-related, outside of the source code tarball.
  • Pick only the changes from the upstream that are verified and/or are really needed (e.g. required fix won't get in without related changes).
  • Preferably add patches only after they were already accepted upstream and passed all the checks they run themselves separately. This is not always the case, but keeps you at the safe side.
  • Always squash commits per a topic. That is, one patch (file) per one PR please. Do not make few .patch files, related to the same problem. Do not use fixup (discards the commit message), but squash. This way you will always keep the commit messages inside one big message of the patch, hence everyone can look up what happened and what commits were actually included. IOW, be verbose in commit messages, be sparse in physical files!

Submitting to build.opensuse.org

  • Only submit to systemsmanagement:saltstack:testing/salt
  • ⚠️ Check systemsmanagement:saltstack/salt for changes introduced by openSUSE:Factory (Yes, the openSUSE:Factory maintainers can introduce changes by themselves just to keep Factory working)

Request push access

An example adding a new patch to the 2015.8.3 package

  • Checkout the openSUSE-2015.8.3 branch
  • Add the fix, using cherry-pick of the range from the corresponding upstream branch. In case of conflicts (they usually are normal) fix them in place.
  • Commit the fix to the openSUSE-2015.8.3 branch
  • Run git format-patch v2015.8.3 against this tag
  • ⚠️ If you have more than one patch files appeared, squash them into one file, leaving all the commit messages as one big message. See "Changing an existing patch" part below.
  • Add the latest .patch file to the package
  • Build the package
  • Test the package
  • ⚠️ Perform the final git push only if package is built and all the tests passes!

Changing an existing patch

  • Checkout the openSUSE-2015.8.3 branch
  • Run git rebase -i v2015.8.3 — this will open your $EDITOR
  • In case to correct something within the commit, change pick to edit of the patch you want to change, then save and exit your editor
  • In case to merge many commits into one, use squash technique.
  • Change the file(s)
  • git add, git commit, git rebase --continue
  • Run git format-patch v2015.8.3
  • Move all .patch files to the package
  • Build the package
  • Test the package
  • git push -f if tests passes. Pushing with --force is perfectly OK.

Upgrade to a new upstream release

Example: New 2015.8.x release

Assumptions:

  • Old openSUSE branch: openSUSE-2015.8.3, based on v2015.8.3

  • New release v2015.8.4

  • New openSUSE branch: openSUSE-2015.8.4 based on v2015.8.4

  • git fetch upstream to get your repo up-to-date compared to upstream

  • git fetch opensuse to get your repo up-to-date compared to openSUSE

  • git checkout openSUSE-2015.8.3 to go to the openSUSE-2015.8.3 branch

  • git pull opensuse openSUSE-2015.8.3 to get up-to-date with the openSUSE patches

  • git checkout 2015.8 to go to the 2015.8 branch

  • git pull upstream 2015.8 to get the latest branch state from upstream

  • git checkout v2015.8.4 to place git HEAD to the upstream release tag

  • git checkout -b openSUSE-2015.8.4 to create the new openSUSE release branch

  • git cherry-pick v2015.8.3..openSUSE-2015.8.3 to move all patches from the old openSUSE release branch to the new one. This will automagically detect patches that were merge upstream. You might run into conflicts if a openSUSE patch touches the same code area as an upstream commit. Go fix these conflicts, then git add ..., git cherry-pick --continue resp. git cherry-pick --allow-empty

  • git push opensuse openSUSE-2015.8.4 to push the new branch to opensuse
