Updating bioconda-utils

This section documents the steps required to update bioconda-utils and have it working on Azure DevOps and building packages.

bioconda-utils is currently using Release Please to manage updates, changelogs, and versioning. This works in a specific way, so the steps below walk through the process if you’re not already familiar.

Prefix the PR title, as well as at least one commit in the PR, with one of the following change types. Some special types will change the bioconda-utils version number, as noted below.

  • <type>! (that is, any of the types below ending an exclamation point) indicates a breaking change. PRs with this title will result in a new MAJOR VERSION

  • feat: a new feature. PRs with this title will result in a new MINOR VERSION

  • fix: fixes a bug. PRs with this title will result in a new PATCH VERSION

  • test: changes related to tests

  • chore: for maintenance changes. E.g. dependency version changes (should use a to indicate breaking change in this case)

  • ci: for changes related to CI of bioconda-utils

  • docs: a change that only affects documentation (ReST, comments, docstrings)

  • refactor: a change in code that neither fixes a bug nor adds a feature

  • style: whitespace, formatting, etc

The general workflow is:

  1. Open a pull request to bioconda-utils repo, being sure to use

conventional commit messages in your title.

Why do I need to pay attention to the PR title?

This is part of Release Please, which uses the PR titles (as well as individual commits within the PR) to decide on semantic version bumps. The bioconda-utils repo has a GitHub Action that will check for conventional commit message in the PR title, and the PR will fail without a properly-formatted title.

Note that if you update the PR title to address a failing check, you may need to push an additional commit to trigger the check again (or possibly close and then reopen the PR).

  1. Merge to master branch

    Won't the changes be immediately used?

    Our infrastructure no longer points directly to the master branch of bioconda-utils. Instead, the infrastructure points to specific releases. Merging to master branch does not create a release – see below for how releases are created.

    Release Please monitors the master branch to determine what to add to the special release PR.

  2. Allow Release Please to automatically create a release PR

    What's a release PR?

    A release PR is a special PR automatically create by the Release Please GitHub Action running in the bioconda-utils repo. The release PR will keep track of accumulated changes since the last release. The version in the title of the PR will reflect semantic versioning to use based on the accumulated changes. Here’s an example. Merging the special release PR will create a release.

  3. Merge the release PR to automatically create a new GitHub release of bioconda-utils

    I'm done, right?

    Not done yet…our infrastructure uses the conda package of bioconda-utils, which is in turn hosted on bioconda-recipes. So simply creating a new GitHub release of bioconda-utils is insufficient to use it on our infrastructure. We still need to build the conda package, which happens over on bioconda-recipes.

  4. Allow the autobump bot to detect the new release and create a new PR over on bioconda-recipes to create an updated conda package.

    How are dependencies kept consistent?

    bioconda-utils keeps a requirements.txt file for its own tests. But this needs to match the conda recipe. To double-check this, the recipe over in bioconda-recipes has a test that installs the bioconda_utils-requirements.txt file into the recipe’s test environment, and the test ensures that doing so does not result in any changes to the environment – confirming that the requirements file in the bioconda-utile repo and its meta.yaml in the bioconda-recipes repo match.

  5. Once tests pass, treat it as a typical package: get approval, and then merge.

    What version is used to build the package?

    That new conda package is built using the previous version of bioconda-utils since that’s what’s running on our infrastructure. Merge into bioconda-recipes when tests pass.

  6. Once the conda package is available (check by trying to install locally), update bioconda-common/ to point to the new version

    Where is that file used?

    The file is used in various workflows (like GitHub Actions and Azure DevOps) as a means of having a single central authority on what versions are being used.

At this point, the next time the various workflows run they will get the new version of, which will cause a cache miss and trigger the installation of the version of bioconda-utils specified in that file. bioconda-recipes is now using the updated version..

How do I check?

You can keep an eye on new bioconda-recipe PRs, or maybe close and then reopen an existing one. Look for Azure DevOps log under the “Restore cache” step (it should say cache miss on the first time it runs) and then check “Install bioconda-utils” step to ensure it installed the version you expect.
