buildkite/agent v3.50.0 on GitHub

v3.50.0 (2023-07-18)

This release contains multiple issues:

Severity	Description	Fixed in
Medium	When uploading pipelines, some group steps are not correctly parsed, and were ignored.	✅ Fixed in v3.50.1
Low	Uploading pipelines with empty or zero-length `steps` failed, where they should've been a no-op.	✅ Fixed in v3.50.1
⚠️ Very High	Jobs running on this version of the agent are not cancellable from the UI/API	✅ Fixed in v3.50.2
Medium	When uploading pipelines, if any object in the pipeline YAML contained multiple merge keys, the pipeline would fail to parse. See below for a workaround	⏳ Fix incoming, stay tuned

Workaround for yaml merge key issue

For example, this pipeline would fail to parse:

default_plugins: &default_plugins
  plugins:
    - docker#4.0.0:
        image: alpine:3.14

default_retry: &default_retry
  retry:
    automatic:
      - exit_status: 42

steps:
  - <<: *default_plugins
    <<: *default_retry
    command: "echo 'hello, world!'"

As a workaround for this, you can use yaml array merge syntax instead:

default_plugins: &default_plugins
  plugins:
    - docker#4.0.0:
        image: alpine:3.14

default_retry: &default_retry
  retry:
    automatic:
      - exit_status: 42

steps:
  - <<: [*default_plugins, *default_retry]
    command: "echo 'hello, world!'"
