Collapsible sections lines not hidden in output

GitLab CI/CD
1

Hi,

i’m trying to use collapsible sections like described here Jobs | GitLab , but it seems other than stated in the documentation the lines are not removed from the rendered output.

The first variant is directly from the documentation, the second one was just to change color…

Here’s the html for those lines

Any idea why those are not hidden ?
I’m not sure what i’m doing wrong :frowning:

Hi, please post the .gitlab-ci.yml Part of the configuration and your current GitLab Version?

Hi,

sure this is one example where it happens
And GitLab is current Version 13.7.1 (c97c8073a0e)

build_image_docker:
  stage: build-docker
  image: srv-nexus-oss.mydomain.com/docker:latest
  services:
  - docker:dind
  script:
    - echo -e "section_start:`date +%s`:before_script_section[collapsed=true]\r\e[0K\e[0K\e[33;1mBuilding Docker Image"
    - echo "{\"name\":\"`echo $CI_PROJECT_DIR | cut -d'/' -f 7-`\",\"version\":\"$CI_BUILD_REF_NAME\",\"build_nr\":\"$CI_BUILD_ID\",\"build_date\":\"`date`\"}" >> ci-build.json
    - cat ci-build.json
    - docker login -u $CI_REGISTRY_USER -p $CI_REGISTRY_PASSWORD $CI_REGISTRY  
    - echo $DOCKERREGISTRY_PWD | docker login -u k8s --password-stdin $URL_DOCKERREGISTRY
    - docker pull -q $DOCKER_IMAGE_NAME_LATEST || true
    - docker build --cache-from ${DOCKER_IMAGE_NAME_LATEST} --build-arg env=$CI_COMMIT_REF_NAME -t ${DOCKER_IMAGE_NAME_FULL} -f ./Dockerfile .
    - docker tag ${DOCKER_IMAGE_NAME_FULL} ${DOCKER_IMAGE_NAME_LATEST}
    - docker push $DOCKER_IMAGE_NAME_FULL
    - docker push $DOCKER_IMAGE_NAME_LATEST
    - echo -e "section_end:`date +%s`:before_script_section\r\e[0K"
  interruptible: true
  tags:
    - kubernetes
  rules:
    - if: $CI_MERGE_REQUEST_IID
    - if: $CI_COMMIT_TAG
    - if: $CI_COMMIT_BRANCH

And this is the other part from my screenshot

before_script:
    - echo -e "section_start:`date +%s`:before_script_section[collapsed=true]\r\e[0KRunning before_script"
    - mkdir -p /tmp
    - export VAULT_ADDR=https://vault.mydomain.com
    - export VAULT_TOKEN="$(vault write -field=token auth/jwt/login role=terraform jwt=$CI_JOB_JWT)"
    - echo -e "section_end:`date +%s`:before_script_section\r\e[0K"

Not sure, but I think you don’t need the second clear ANSI Escape Code before adding a Color
Consider the building Docker Image section output:

    - echo -e "section_start:`date +%s`:before_script_section[collapsed=true]\r\e[0K\e[0K\e[33;1mBuilding Docker Image"

\e[0K removes some control char, probably the one which would normally hide this line. Remove one \e[0K and try:

    - echo -e "section_start:`date +%s`:before_script_section[collapsed=true]\r\e[0K\e[33;1mBuilding Docker Image"

I’m having the same issue, could it be because the docker container is using /bin/sh, and doesn’t have the support for escape sequences like in Bash?

I tried this suggestion, but it didn’t help. I’m suspecting it’s to do with the terminal in the container doing something with the escape sequences. Tried using echo and printf, but no difference.

After series of experiments, it seems that I found a way to make it work!

this one doesn’t hide the ugly block:

build_front:
  extends: .build_front_template
  script:
    - printf "\e[0Ksection_start:`date +%s`:execution_section_0[collapsed=true]\r\e[0KBuilding frontend\n"
    - yarn build --version=${RELEASE_VERSION} --git_branch="${CI_COMMIT_REF_NAME}" --revision_number="${CI_COMMIT_SHA}"
    - printf "section_end:`date +%s`:execution_section_0\r\e[0K"

while this one does! :partying_face:

build_front:
  extends: .build_front_template
  script:
    - >
      printf "\e[0Ksection_start:`date +%s`:execution_section_0[collapsed=true]\r\e[0KBuilding frontend\n"
      yarn build --version=${RELEASE_VERSION} --git_branch="${CI_COMMIT_REF_NAME}" --revision_number="${CI_COMMIT_SHA}"
      printf "section_end:`date +%s`:execution_section_0\r\e[0K"

P.S. Using printf instead of echo doesn’t make sense, so ignore it
