Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟡 Moderate · up to The new profiling workflow currently uses mutable CI dependencies, broader-than-necessary repository permissions, and cleanup behavior that can skip profiling analysis after a failed build; concurrent pull-request runs may also consume excessive runner capacity. The PR should be merged only after these bounded CI security, result-integrity, and resource-use risks are fixed or explicitly accepted.

equivalent concurrency is already enforced by the caller, preserve that

a reviewed ClangBuildAnalyzer commit rather than its default branch.

captures shammake’s exit status without immediately exiting, always runs
ClangBuildAnalyzer --stop during cleanup, then re-raises the original build
status. Ensure the subsequent analysis runs whenever capture_build.bin exists,
including after a failed build.
- Around line 4-20: Set contents: read at the workflow-level permissions

same job-level permission to shamrock_linux_acpp_build_profile in

GitHub Actions reusable workflows permissions caller job called workflow workflow_call workflow_dispatch official documentation
💡 Result:
In GitHub Actions, the permissions of a called (reusable) workflow are strictly governed by the permissions defined in the calling job. Key principles regarding these permissions include: 1. Permission Capping: The GITHUB_TOKEN permissions available to a called workflow are capped by the permissions granted in the calling job [1][2][3]. A called workflow can downgrade permissions but cannot elevate them beyond what the caller provides [1][3]. If a called workflow requests a scope that the caller has not granted, the run will fail with an error such as: "the workflow is requesting 'X', but is only allowed 'Y'" [2][4]. 2. Caller Job Configuration: You define permissions for the caller job using the permissions key within that specific job [1][5]. If this key is omitted in the calling job, the called workflow will default to the standard repository permissions for the GITHUB_TOKEN [1][3]. To ensure security, it is best practice to explicitly declare the minimum necessary permissions in the caller job [6][7][8]. 3. Called Workflow Declaration: While the caller job dictates the maximum permitted scope, the called workflow should also explicitly declare its required permissions [2]. The effective permissions for the called workflow will be the intersection of the permissions granted by the caller and the permissions requested by the called workflow [2]. 4. Chain Propagation: This restriction applies throughout chains of nested reusable workflows (A > B > C) [9][10]. Permissions can only be maintained or reduced, never elevated, as they pass down the chain [9][3]. 5. Workflow Triggers: Reusable workflows are defined using the workflow_call trigger [10][5]. They can be triggered manually in the calling repository using workflow_dispatch, but the reuse mechanism itself relies on the jobs.<job_id>.uses syntax [9][6][5]. For secure implementation, follow the principle of least privilege: explicitly configure permissions in the caller job to grant only the access required by the called workflow, and ensure the called workflow also specifies its required permissions to enforce the intersection of these sets [2][7][8].

Apply least-privilege permissions at both workflow boundaries.
Add contents: read at workflow level in .github/workflows/shamrock-acpp-clang-build-profile.yml and at job level for shamrock_linux_acpp_build_profile in .github/workflows/main_workflow.yml. The called workflow uses actions/checkout, and the caller otherwise passes the repository’s default token permissions.

🚀 Performance & Scalability | 🔵 Trivial
Limit concurrent profiling runs.
This job can occupy a runner for up to 120 minutes, but this workflow defines no concurrency group. GitHub permits multiple workflow runs concurrently by default. Add a group keyed by the pull request or ref, with cancel-in-progress: true for obsolete pull-request commits, or confirm that the caller already enforces equivalent behavior. (docs.github.com)

Pin all executable CI dependencies to immutable references.
Use an image digest, full commit SHAs for both actions/checkout and actions/upload-artifact, and a reviewed commit for ClangBuildAnalyzer instead of its default branch.

GitHub Actions default bash shell --noprofile --norc -eo pipefail run step upload-artifact if-no-files-found default behavior
💡 Result:
In GitHub Actions, the default behavior for the bash shell and the upload-artifact action is as follows: Default Bash Shell Behavior When you explicitly specify shell: bash in a GitHub Actions workflow, the runner executes the command with bash --noprofile --norc -eo pipefail {0} [1][2]. The inclusion of --noprofile and --norc ensures that the shell does not load startup files like .bashrc or .bash_profile, providing a consistent environment across runs [3][4]. The -e flag causes the script to exit immediately if any command fails, and pipefail ensures that the pipeline returns a non-zero exit code if any command in the pipeline fails [1][2]. If you do not specify a shell (i.e., using the default shell), non-Windows runners execute bash -e {0} [1][2]. While this default still provides error-exiting behavior via -e, it does not explicitly include the pipefail option or the --noprofile --norc flags in the same way as the explicit bash declaration [1][2]. Upload-Artifact if-no-files-found Behavior The upload-artifact action provides the if-no-files-found input to control the workflow's behavior when the specified path does not match any files [5][6]. The default behavior is warn, which means the action will complete successfully but will output a warning in the workflow logs [5][7][8]. You can override this default by setting if-no-files-found to one of the following [5][6][8]: - warn: (Default) Outputs a warning but does not fail the action [5][8]. - error: Fails the action with an error message [5][6]. - ignore: Suppresses all warnings and errors; the action does not fail [5][8].

Stop ClangBuildAnalyzer before propagating build failures.
Because shell: bash enables -e, a failed shammake skips ClangBuildAnalyzer --stop; the analysis step is then skipped. Capture the build status, run --stop during cleanup, and re-raise the original status. Run analysis when capture data exists, even after a build failure.
