Add conditional retry for flaky GTFS download step in mt-download-data workflow

[Copilot]

MT download data (& archive) intermittently fails, but often succeeds on rerun. This updates the workflow to automatically perform one delayed retry only when the first attempt fails.

• Workflow resilience

  • Added id: mt-download-data to the primary download step.
  • Set the primary step to continue-on-error: true so failure can be handled by a follow-up retry step in the same job.

• Targeted retry behavior

  • Added a new step immediately after the primary download step.
  • Retry step runs only when steps.mt-download-data.outcome == 'failure'.
  • Retry step waits 60 seconds, then reruns the same download script (./agency-parser/download.sh).

- name: MT download data (& archive)
  if: steps.check-input-url.outputs.has_input_url == 'true'
  id: mt-download-data
  continue-on-error: true
  run: ./agency-parser/download.sh
  timeout-minutes: 20

- name: MT download data (& archive) retry after 1 min
  if: ${{ steps.check-input-url.outputs.has_input_url == 'true' && steps.mt-download-data.outcome == 'failure' }}
  run: |
    echo ">> Download failed. Retrying in 1 minute..."
    sleep 60
    ./agency-parser/download.sh
  timeout-minutes: 20

Code Review

This pull request updates the GitHub Actions workflow to retry the data download step after a 1-minute delay if the initial attempt fails. The feedback suggests increasing the job-level timeout to at least 45 minutes to accommodate both the initial run and the retry attempt within the overall job limit. Additionally, it recommends simplifying the retry step's conditional expression by removing redundant checks and expression syntax.

Code Review

This pull request updates the GitHub Actions workflow mt-download-data.yml by increasing the overall job timeout from 30 to 45 minutes and introducing a retry mechanism for the data download step. If the initial download fails, the workflow will now wait for 1 minute before retrying the download. I have no feedback to provide as there are no review comments to assess.
