Testing Recipes Locally

Queue times on CircleCI may sometimes make it more convenient and faster to work on complex packages locally. There are several ways to do so, each with their own caveats.

Using the Circle CI Client

You can execute an almost exact copy of our Linux build pipeline by installing the CircleCI client locally and running it from the folder where your copy of bioconda-recipes resides:

# Ensure the build container is up-to-date
docker pull bioconda/bioconda-utils-build-env:latest

# Run the build locally
circleci build

You will have to have “commited” some changes as described above. The command will run our build system just as it is run online in a docker container. It will detect which recipes where modified using the git history and proceed with linting and building those.

Please note that this will only run the Linux build steps.

Using the “Bootstrap” Method

Due to technical limitations of the Circle CI client, the above test does not run the more stringent mulled-build tests. To do so, use the following commands:

./bootstrap.py /tmp/miniconda
source ~/.config/bioconda/activate

# optional linting
bioconda-utils lint --git-range master

# build and test
bioconda-utils build --docker --mulled-test --git-range master

The above commands do the following:

  • Install a separate miniconda installation in a temporary directory:
    • Set up bioconda channels,

    • install bioconda-utils dependencies into the root environment of that installation,

    • and write the file ~/.config/bioconda/activate

  • Source that new file to specifically activate the root environment of the new installation

  • Run bioconda-utils in the new installation:
    • The lint command will run the lint checks on your recipes

    • The build command will run the build pipeline

Note

  • You can select recipes to lint/build using --git-range master, which which will select those recipes that have been changed between your master and your branch. Or you can specify recipes directly using --packages mypackage1 mypackage2.

  • The --docker flag instructs bioconda-utils to execute the build within a docker container. On MacOS, this will do a Linux build in addition to the local MacOS build.

  • The --mulled-test flag instructs bioconda-utils to repeat the recipes test in a clean, freshly created docker container to ensure that the package does not depend on anything that happens to be included in the build container.

If you do not have access to Docker, you can still run the basic test by telling the bootstrap setup to not use docker, and by excluding the --docker and --mulled-test arguments in the last command:

./bootstrap.py --no-docker /tmp/miniconda
source ~/.config/bioconda/activate
bioconda-utils build --git-range master

Using the “Debug” Method

  • Explain how to use conda debug for difficult recipes.

  • Explain how to create patch series.
