Cirrus-ci-docs: Error: field 'null' should be a value or at most list of values

[awnumar]

My .cirrus.yml file looks like:

linux_task:
  container:
    image: alpine:latest
  env:
    - GOPATH: ${HOME}/go
    - PATH: ${GOPATH}/bin:${PATH}
    - GOPROXY: https://proxy.golang.org
  setup_script:
    - apk add go
    - go version
    - mkdir ${GOPATH}/src/${CIRRUS_REPO_OWNER}
    - cd ${GOPATH}/src/${CIRRUS_REPO_OWNER}
    - git clone ${CIRRUS_REPO_CLONE_URL}
    - cd ${CIRRUS_REPO_NAME}
  build_script:
    - go build -race -v ./...
  test_script:
    - go test -race -count=100 ./...
    - go test -race -v -count=1 ./...

But I get the following error when it attempts to run:

FAILED_PRECONDITION: Field 'null' should be a value or at most list of values!

I thought it might be an issue with white-space but this doesn't seem to be the case.

Hey! Thanks for your question.
Because this is a precondition, it seems to be an issue with your .cirrus.yml. If I remember correctly, I don't think you can use ${ITEM} in env variable declarations yet.

Pretty sure there is an issue mentioning this somewhere.

[fkorotkov]

It's because env is expected to be a mapping and not a list:

env:
    GOPATH: ${HOME}/go
    PATH: ${GOPATH}/bin:${PATH}
    GOPROXY: https://proxy.golang.org

BTW why don't you use golang containers like in an example?

[RDIL]

Ah, that looks like the issue. I agree, containers would be much quicker.

[awnumar]

@fkorotkov That makes sense, thanks!

I considered using the golang images but I need to run tests on specific operating systems and the golang packages weren't flexible enough for this. Are these commands good enough to clone the right branch?

- git clone https://${CIRRUS_REPO_CLONE_TOKEN}@github.com/${CIRRUS_REPO_FULL_NAME}.git
- cd ${CIRRUS_REPO_NAME}
- git checkout ${CIRRUS_BRANCH}

[fkorotkov]

I've added such syntax support in the parser but please still use env as a map until the fix is deployed 😅

[fkorotkov]

@awnumar please check this example with a custom clone command.

[awnumar]

@fkorotkov Thanks for that, I didn't notice it in the docs. However it has an issue every time I try to use it. If I do the following:

env:
    GOPROXY: https://proxy.golang.org
    MODULEPATH: /tmp/go/src/github.com/${CIRRUS_REPO_FULL_NAME}
install_script:
    - apk add go
    - apk add git
    - mkdir -p /tmp/go/src/github.com/${CIRRUS_REPO_OWNER}
clone_script: |
    if [[ -z "$CIRRUS_PR" ]]; then
      git clone --recursive --branch=$CIRRUS_BRANCH https://x-access-token:${CIRRUS_REPO_CLONE_TOKEN}@github.com/${CIRRUS_REPO_FULL_NAME}.git ${MODULEPATH}
      git reset --hard $CIRRUS_CHANGE_IN_REPO
    else
      git clone --recursive https://x-access-token:${CIRRUS_REPO_CLONE_TOKEN}@github.com/${CIRRUS_REPO_FULL_NAME}.git ${MODULEPATH}
      git fetch origin pull/$CIRRUS_PR/head:pull/$CIRRUS_PR
      git reset --hard $CIRRUS_CHANGE_IN_REPO
    fi
    export CIRRUS_WORKING_DIR=${MODULEPATH}
    export GOPATH=/tmp/go
    export PATH=${GOPATH}/bin:${PATH}

then I get the error:

Cloning into '/tmp/go/src/github.com/awnumar/memguard'...
fatal: not a git repository (or any parent up to mount point /)
Stopping at filesystem boundary (GIT_DISCOVERY_ACROSS_FILESYSTEM not set).
Exit status: 128

I've tried a number of things but I can't seem to get rid of it.

[fkorotkov]

This should work:

container:
  image: alpine:latest

test_task:
  env:
    GOPROXY: https://proxy.golang.org
    GOPATH: /tmp/go
    PATH: ${GOPATH}/bin:${PATH}
    CIRRUS_WORKING_DIR: /tmp/go/src/github.com/${CIRRUS_REPO_FULL_NAME}
  install_script:
      - apk add go git
  clone_script: |
      if [[ -z "$CIRRUS_PR" ]]; then
        git clone --recursive --branch=$CIRRUS_BRANCH https://x-access-token:${CIRRUS_REPO_CLONE_TOKEN}@github.com/${CIRRUS_REPO_FULL_NAME}.git ${CIRRUS_WORKING_DIR}
        git reset --hard $CIRRUS_CHANGE_IN_REPO
      else
        git clone --recursive https://x-access-token:${CIRRUS_REPO_CLONE_TOKEN}@github.com/${CIRRUS_REPO_FULL_NAME}.git ${CIRRUS_WORKING_DIR}
        git fetch origin pull/$CIRRUS_PR/head:pull/$CIRRUS_PR
        git reset --hard $CIRRUS_CHANGE_IN_REPO
      fi

You're a wizard, thank you.
