| # A workflow that implements similar logic to actions/stale. | |
| # | |
| # Compared to actions/stale, it is implemented to make API requests proportional | |
| # to the number of stale PRs, not the total number of issues in the repo. This | |
| # is because PyTorch has a lot of issues/PRs, so the actions/stale runs into | |
| # rate limits way too quickly. | |
| # | |
| # The behavior is: | |
| # - If a PR is not labeled stale, after 60 days inactivity label the PR as stale and comment about it. | |
| # - If a PR is labeled stale, after 30 days inactivity close the PR. | |
| # - `high priority` and `no-stale` PRs are exempt. | |
