Warns and then closes issues and PRs that have had no activity for a specified amount of time.

The configuration must be on the default branch and the default values will:

• Add a label "Stale" on issues and pull requests after 60 days of inactivity and comment on them
• Close the stale issues and pull requests after 7 days of inactivity
• If an update/comment occur on stale issues or pull requests, the stale label will be removed and the timer will restart

For the execution of this action, it must be able to fetch all issues and pull requests from your repository.
In addition, based on the provided configuration, the action could require more permission(s) (e.g.: add label, remove label, comment, close, etc.).
This can be achieved with the following configuration in the action if the permissions are restricted:

permissions:
  issues: write
  pull-requests: write

You can find more information about the required permissions under the corresponding options that you wish to use.

Every argument is optional.

Personal Access Token (PAT) that allows the stale workflow to authenticate and perform API calls to GitHub.
Under the hood, it uses the @actions/github package.

Default value: ${{ github.token }}

The idle number of days before marking the issues or the pull requests as stale (by adding a label).
The issues or the pull requests will be marked as stale if the last update (based on GitHub issue field updated_at) is older than the idle number of days.
It means that any updates made, or any comments added to the issues or to the pull requests will restart the counter of days before marking as stale.
However, if you wish to ignore this behaviour so that the creation date (based on GitHub issue field created_at) only matters, you can disable the ignore-updates option.

If set to a negative number like -1, no issues or pull requests will be marked as stale automatically.
In that case, you can still add the stale label manually to mark as stale.

The label used to stale is defined by these two options:

• stale-issue-label
• stale-pr-label

A comment can also be added to notify about the stale and is defined by these two options:

• stale-issue-message
• stale-pr-message

You can fine tune which issues or pull requests should be marked as stale based on the milestones, the assignees, the creation date and the missing/present labels from these options:

• exempt-issue-labels
• exempt-pr-labels
• only-labels
• any-of-labels
• start-date
• exempt-milestones
• exempt-all-milestones
• exempt-assignees
• exempt-all-assignees
• ignore-updates

Default value: 60

Useful to override days-before-stale but only for the idle number of days before marking the issues as stale.

Default value: unset

Useful to override days-before-stale but only for the idle number of days before marking the pull requests as stale.

Default value: unset

The idle number of days before closing the stale issues or the stale pull requests (due to the stale label).
The issues or the pull requests will be closed if the last update (based on GitHub issue field updated_at) is older than the idle number of days.
Since adding the stale label will alter the last update date, we can calculate the number of days from this date.

If set to a negative number like -1, the issues or the pull requests will never be closed automatically.

The label used to stale is defined by these two options:

• stale-issue-label
• stale-pr-label

Default value: 7

Override days-before-close but only for the idle number of days before closing the stale issues.

Default value: unset

Override days-before-close but only for the idle number of days before closing the stale pull requests.

Context:
This action performs some API calls to GitHub to fetch or close issues and pull requests, set or update labels, add comments, delete branches, etc.
These operations are made in a very short period of time — because the action is very fast to run — and can be numerous based on your project action configuration and the quantity of issues and pull requests within it.
GitHub has a rate limit and if reached will block these API calls for one hour (or API calls from other actions using the same user (a.k.a.: the github-token from the repo-token option)).
This option helps you to stay within the GitHub rate limits, as you can use this option to limit the number of operations for a single run.

Purpose:
This option aims to limit the number of operations made with the GitHub API to avoid reaching the rate limit.

Based on your project, your GitHub business plan and the date of the cron job you set for this action, you can increase this limit to a higher number. If you are not sure which is the right value for you or if the default value is good enough, you could enable the logs and look at the end of the stale action.
If you reached the limit, you will see a warning message in the logs, telling you that you should increase the number of operations. If you choose not to increase the limit, you might end up with unprocessed issues or pull requests after a stale action run.

When debugging, you can set it to a much higher number like 1000 since there will be fewer operations made with the GitHub API.
Only the actor and the batch of issues (100 per batch) will consume the operations.

Default value: 30

Automatically remove the stale label when the issues or the pull requests are updated (based on GitHub issue field updated_at) or commented.

Default value: true
Required Permission: issues: write and pull-requests: write

Override remove-stale-when-updated but only to automatically remove the stale label when the issues are updated (based on GitHub issue field updated_at) or commented.

Default value: unset

A comma delimited list of labels to remove when a stale issue or pull request receives activity and has the stale-issue-label or stale-pr-label removed from it.

Warning: each label results in a unique API call which can drastically consume the limit of operations-per-run.

Default value: unset
Required Permission: pull-requests: write

Run the stale workflow as dry-run.
No GitHub API calls that can alter your issues and pull requests will happen.
Useful to debug or when you want to configure the stale workflow safely.

Default value: false

Change the order used to fetch the issues and pull requests from GitHub:

• true is for ascending.
• false is for descending.

It can be useful if your repository is processing so many issues and pull requests that you reach the operations-per-run limit.
Based on the order, you could prefer to focus on the new content or on the old content of your repository.

Default value: false

The start date is used to ignore the issues and pull requests created before the start date.
Particularly useful when you wish to add this stale workflow on an existing repository and only wish to stale the new issues and pull requests.

If set, the date must be formatted following the ISO 8601 or RFC 2822 standard.

Default value: unset

If set to true, the stale workflow will automatically delete the GitHub branches related to the pull requests automatically closed by the stale workflow.

Default value: false
Required Permission: pull-requests: read

Collects and display statistics at the end of the stale workflow logs to get a summary of what happened during the run.
This option is only useful if the debug output secret ACTIONS_STEP_DEBUG is set to true in your repository to display the logs.

Default value: true

The option days-before-stale will define the number of days before considering the issues or the pull requests as stale.
In most cases, the purpose of this action is to only stale when necessary so if any update occurs or if a comment is added to them, the counter will restart.
Nonetheless, if you don't care about this, and you prefer to stick to this number of days no matter the update, you can enable this option.
Instead of comparing the number of days based on the GitHub issue field updated_at, it will be based on the GitHub issue field created_at.

Default value: false

Useful to override ignore-updates but only to ignore the updates for the issues.

Default value: unset

Useful to override ignore-updates but only to ignore the updates for the pull requests.

Default value: unset

Logs:
To see the debug output from this action, you must set the secret ACTIONS_STEP_DEBUG to true in your repository.
There are many logs, so this can be very helpful!

Statistics:
If the logs are enabled, you can also enable the statistics log which will be visible at the end of the logs once all issues were processed.
This is very helpful to have a quick understanding of the whole stale workflow.
Set enable-statistics to true in your workflow configuration file.

Dry-run:
You can run this action in debug only mode (no actions will be taken on your issues and pull requests) by passing debug-only to true as an argument to the action.

More operations:
You can increase the maximum number of operations per run by passing operations-per-run to 1000 for example which will help you to handle more operations in a single stale workflow run.
If the debug-only option is enabled, this is very helpful because the workflow will (almost) never reach the GitHub API rate, and you will be able to deep-dive into the logs.

Job frequency:
You could change the cron job frequency in the stale workflow to run the stale workflow more often.
Usually, this is not very helpful though.
