chore: Add static-code-analysis CI pipeline - #342
Conversation
WalkthroughThe pull request adds a GitHub Actions workflow for static code analysis. It filters triggers, selects eligible references, configures restricted permissions, and dispatches scan metadata to a shared workflow repository. ChangesStatic analysis workflow

- Line 85: Update the branch mapping used by the workflow’s ref expression so
each eligible source branch (main, v0.0, v0.1, and v0.2) resolves to an existing
target branch in run-ai/saas-configuration, or create the corresponding target
branches there. Ensure the dispatch ref passed by the static analysis workflow
matches the supported target branches.

duplicate scans through both create and push.

GitHub Actions create event push event branch creation workflow both events
💡 Result:
You can trigger a GitHub Actions workflow using both push and create events by listing them under the on key in your workflow configuration [1][2][3]. Because these are separate event types, GitHub will trigger a separate workflow run for each event that occurs [2]. Example configuration: yaml on: push: branches: - '' create: ### Key Considerations * Separate Runs: If a branch is created via a push (which is common in some workflows), both events might technically be relevant [2]. If both occur, GitHub will initiate distinct workflow runs for each [2]. * Distinguishing Events: To execute specific logic only when a certain event triggers the workflow, you can use the github.event_name context variable within your job definitions [3]: yaml jobs: my-job: runs-on: ubuntu-latest if: github.event_name == 'create' steps: - name: Run only on branch creation run: echo "Branch was created!" * Context Data: When triggered by a create event, you can access specific metadata like github.event.ref_type (which will be branch or tag) and github.event.ref (the name of the branch or tag created) to further refine your logic [3]. * Workflow Limitations: Note that using push and create simultaneously does not inherently provide an "exclusive" trigger mechanism; if you need to prevent one from running under certain conditions, you must use conditional if expressions in your jobs or steps [4][3]. Alternatively, some users prefer to use only the push event and check the event metadata (e.g., github.event.created) within the workflow to differentiate behavior [4].

site:docs.github.com GitHub Actions push event create branch both events branch creation
💡 Result:
In GitHub Actions, the push event and the create event are distinct triggers that serve different purposes regarding branch creation [1][2]. The push event is triggered when commits are pushed to a repository, which includes creating a new branch (if that push contains a new ref) or updating an existing one [1][3][2]. Because pushing a new branch often involves pushing at least one commit, the push event is commonly used as the primary way to trigger workflows on branch creation [4][2]. The create event is triggered specifically when a Git reference (such as a branch or a tag) is created in the repository [1][3]. Unlike the push event, it is not dependent on a commit being pushed; it reacts directly to the creation of the reference itself [1][5]. To handle both events or specifically distinguish between them in your workflows, you can configure your workflow to listen for one or both: on: push: create: When using both, you can use the github.event_name context within your workflow steps or jobs to determine which event triggered the run [6][7]. For example: jobs: example-job: runs-on: ubuntu-latest steps: - if: github.event_name == 'push' run: echo "Triggered by a push (e.g., commit or branch creation)" - if: github.event_name == 'create' run: echo "Triggered by branch or tag creation" Key differences: - Trigger condition: Push triggers on code/tag updates [1][2]; Create triggers strictly when a ref is created [1][3]. - Data context: The github.event payload will contain different information depending on the trigger [6]. For instance, the create event payload specifically identifies the created ref and ref_type (branch or tag) [3]. - Behavior: If you only want to act when a branch is created, you might prefer the create event [1]. If you want to act whenever code is added to a branch, the push event is more appropriate [2].

site:docs.github.com actions workflow syntax branches filter + [0-9] glob pattern
💡 Result:
GitHub Actions workflow branch filters do not explicitly support bracket-style glob character classes (such as [0-9]) [1][2]. The official documentation for workflow syntax specifies that branch and tag filters support glob patterns using characters like *,, +,?, and! [1][2]. These patterns allow you to match more than one branch name [1][2]. If a branch name contains these special characters and you require a literal match, you must escape each character with a backslash () [1][2]. Because the documented glob support for branches and tags is limited to specific wildcard and negation characters, using [0-9] for numeric matching is not a supported feature in the workflow syntax for branch filtering [1][2].

🌐 Web query:
GitHub Actions branch pattern v[0-9]+.[0-9]+ matches v1.2
💡 Result:
Yes, the GitHub Actions branch pattern v[0-9]+.[0-9]+ matches v1.2 [1]. GitHub Actions uses glob patterns for branch and tag filters, which support basic character ranges such as [0-9] [2][3]. In this context: 1. The pattern v[0-9]+.[0-9]+ is interpreted as: - v: A literal 'v'. - [0-9]+: One or more digits (matching '1'). -.: A literal dot. - [0-9]+: One or more digits (matching '2'). Since v1.2 satisfies these components, the pattern successfully matches it [1]. Important technical considerations for these patterns: - Glob Syntax vs. Regex: These are not full regular expressions [4][5]. While [0-9] works as a character class, other regex features (like non-capturing groups or complex quantifiers) are not supported and may lead to errors or unexpected behavior [4][5]. - Quote Requirement: When using square brackets in YAML workflow files, you must enclose the pattern in quotes (e.g., 'v[0-9]+.[0-9]+') to prevent YAML parsing errors [6]. - Glob Matching Behavior: Remember that simple wildcards like * do not cross directory slashes; if you need to match deeper paths, you must use [3]. However, for simple version strings like v1.2, standard glob matching works as expected [1].

site:docs.github.com/en/actions "You can use the following special characters" branches tags filters [0-9]
💡 Result:
In the context of software development, specifically within systems like GitHub Actions, special characters, branches, tags, and filters (including numeric ranges like [0-9]) are primarily used to define workflow triggers and pattern matching [1][2][3]. Glob Pattern Matching When configuring workflows to run on specific branches or tags, you can use glob patterns to match multiple names simultaneously [1][2]. These patterns incorporate special characters that function as wildcards or operators: * *: Matches zero or more characters (e.g., releases/* matches releases/v1 and releases/v2) [1][4]. * : Matches zero or more directories or characters (e.g., in path filtering) [1][5]. * ?: Matches a single character [1][2]. * +: Matches one or more of the preceding character [1][2]. * !: Used as a negation operator to exclude specific branches or tags [1][6]. When using !, you must typically also include at least one pattern that does not use negation [1][6]. * [0-9]: A character class range used within patterns to match any single digit from 0 to 9. This is standard glob/shell-style syntax supported for fine-grained filtering of branch or tag names (e.g., feature-[0-9] matches feature-1, feature-2, etc.). Escaping Characters If a branch or tag name literally contains any of these special characters and you intend to match that name exactly, you must escape the characters using a backslash (\) [1][2]. Workflow Filters Filters like branches, branches-ignore, tags, and tags-ignore allow you to restrict when a workflow executes [1][6]. You cannot use both inclusive and exclusive filters (e.g., branches and branches-ignore) for the same event in a single workflow; instead, use the ! operator within the inclusive filter to achieve both goals [1][6]. These filters also often interact with path filters, where the workflow only proceeds if all defined conditions are satisfied [5].

Remove the create trigger or add event-level deduplication.
For branches such as v1.2 or release-1.2, pushing the initial commit can emit both create and push. Both workflow runs dispatch the same scan.

Create the required target branches or update the branch mapping.
The current eligible source branches (main, v0.0, v0.1, and v0.2) do not resolve to master, v0.0, v0.1, or v0.2 in run-ai/saas-configuration. The dispatch therefore cannot start for these branches.
