GitHub Actions documentation secrets unavailable fork pull request unset empty string default shell bash pipefail

💡 Result:

GitHub Actions behavior regarding secrets in fork pull requests and shell execution is documented as follows: Secrets in Fork Pull Requests Workflows triggered by the pull_request event from a forked repository do not have access to repository or environment secrets [1][2][3]. This is a security feature designed to prevent untrusted code in a fork from accessing sensitive credentials [1][3]. When a step in such a workflow attempts to access a secret, it will receive an empty string [1]. To handle this, common practices include using conditional logic to skip secret-dependent steps when the event originates from a fork (e.g., using if: github.event.pull_request.head.repo.fork == false) [1] or using the pull_request_target event for trusted automation, which runs in the context of the base repository and has access to secrets [4][5][6]. Note that pull_request_target requires careful security management to avoid executing untrusted code [4][7]. Default Shell and pipefail When using the run keyword in GitHub Actions on Linux/macOS runners, the shell behavior depends on whether a shell is explicitly specified [8][9]. 1. Explicit bash: When shell: bash is specified, GitHub uses the command bash --noprofile --norc -eo pipefail {0} [8][9]. The -eo pipefail flags ensure that the script exits immediately if a command fails (-e) and that the pipeline's exit code is determined by the last command to exit with a non-zero status (-o pipefail) [10][9]. 2. Default (Unspecified): If no shell is specified, the default shell on Linux/macOS runners is effectively bash -e {0} [8][11]. While this includes the -e (errexit) flag for fail-fast behavior, it does not include the pipefail option by default [10][9]. To ensure pipefail behavior when the shell is not explicitly set, you should either explicitly define shell: bash or include set -o pipefail in your run script [10][9].

두 워크플로의 plist 생성 단계에서 입력과 출력을 검증하십시오.

GOOGLE_SERVICE_INFO_BASE64가 설정되지 않으면 빈 문자열이 전달될 수 있습니다. 현재 명령은 빈 파일을 성공적으로 생성합니다. Base64로 디코드되지만 plist가 아닌 값도 통과합니다.

  • .github/workflows/fastlane_ci.yml#L39-L44: 디코드 전에 시크릿을 검사하고, 생성 후 plutil -lint를 실행하십시오.
  • .github/workflows/build_test.yml#L26-L30: 동일한 검사를 ByeBoo-iOS/ByeBoo-iOS/GoogleService-Info.plist에 적용하십시오.
