GitHub Actions inputs context available workflow_dispatch workflow_call push trigger undefined context expression

💡 Result:

The inputs context in GitHub Actions is strictly limited to workflows triggered by the workflow_dispatch event (manually) or the workflow_call event (reusable workflows) [1][2][3]. It is not available for the push trigger [4][5]. Key points regarding the availability and behavior of the inputs context: 1. Trigger Availability: The inputs context is only populated when a workflow is triggered by workflow_dispatch or workflow_call [1][2]. If you attempt to reference the inputs context in a workflow triggered by a push event, the values will be undefined (or empty), as the inputs configuration block is not supported for push triggers [4][5]. 2. Handling Multiple Triggers: If a single workflow file defines both workflow_dispatch and other triggers (like push), the inputs context will only contain values when the workflow is manually triggered [3][5]. For non-manual triggers, attempting to access ${{ inputs.<input_name> }} will result in an empty or undefined value [4][5]. 3. Expression Context: Because the inputs context is undefined for push triggers, using expressions like ${{ inputs.my_input }} in those runs will not yield the expected results [5]. Workflow authors typically handle this by using conditional logic based on the event name (e.g., if: ${{ github.event_name == 'push' || inputs.my_input }}) or by separating concerns into different workflows where one acts as a reusable workflow (workflow_call) that is invoked by other workflows [4][5]. 4. Compatibility: While the inputs context is the preferred way to access inputs, values passed via workflow_dispatch are also available in the github.event.inputs context for backward compatibility [6][7][3]. Note that github.event.inputs converts all values to strings, whereas the inputs context preserves types like booleans [6][7].

Citations:


Use a defined input source for branch, date, and sha.

This workflow runs only on push, so the inputs context is unavailable. These expressions can resolve to empty values before custom-job.yaml receives them. Use push-event values or declare a supported input trigger. actionlint reports the same issue in the existing jobs.

for the push trigger instead of the unavailable inputs context, matching the

Leaving this one — inputs.branch/date/sha is the existing convention for custom-job.yaml callers in this push-triggered workflow (4 jobs on main already do it, and actionlint flags those identically). The new job just matches its neighbour pandas-tests; changing only this one would make it inconsistent, so it belongs in a repo-wide cleanup rather than here.

@galipremsagar, the consistency rationale is valid. However, inputs.branch, inputs.date, and inputs.sha remain unavailable for this push-triggered workflow.

A repository-wide cleanup is appropriate. Please consider opening a follow-up issue to update all affected custom-job.yaml callers together. This PR still adds three new invalid references, so this finding remains applicable.

"""
Merge the per-module summaries produced by ``summarize-test-results.py`` for
several test shards into a single summary.

Each shard runs a disjoint subset of the suite (see the ``--num-shards``
sharding in ``pandas-testing-plugin.py``), so the combined result for a module
is obtained by summing every numeric field (test counts and the GPU/CPU
function-call counters) across the shards. The same module may appear in more
than one shard because sharding is per test, not per module.

python merge-results.py shard-0/pr-results.json shard-1/pr-results.json > pr-results.json
