[ISSUE #4206] Add github-action 'stale' bot to this repo

[Pil0tXia]

Fixes #4206.

Motivation

Please see #4206.

If an issue or pull request remains inactive for a certain period of time, it will be automatically closed.

Modifications

I have set up a whitelist for pull requests with the help wanted label and for issues with the labels pinned, discussion, good first issue, Hacktoberfest and help wanted.

For Contributors

The good first issue list is maintained by @Alonexc . If a pull request remains inactive for an extended period, it will be closed. However, if the assignee has not even submitted the pull request, it cannot be automatically handled. This decision depends on Alonexc's preference. If maintaining it becomes too burdensome, I suggest removing this whitelist and adding the help wanted label to good first issues that have been inactive for a long time and triggered the stale status.

For Maintainers

Pinned issues and to-do lists need to be labeled with the pinned or discussion or help wanted tag.

• [Good First Issue List] Issues for first-time contributors #888 just this issue
• All issues in What are we doing now? (We Want You) #3873

Documentation

• Does this pull request introduce a new feature? (yes)
• If yes, how is the feature documented? (JavaDocs)
• If a feature is not applicable for documentation, explain why?
• If a feature is not documented yet in this PR, please create a followup issue for adding the documentation

@Alonexc Hello Alonexc, I noticed that not all of the good first issues were labeled good first issue, as a resualt the good first issue label added to exempt (or whitelist) will not cover all of the good first issues.

Considering this situation and comparing with the solution I mentioned which "removing this whitelist and adding the help wanted label to good first issues that have been inactive for a long time and triggered the stale status", would you think it would be better to remove the good first issue exempt?

[Alonexc]

Hi, I think it's OK, the tag will be marked when it's raised, and if some issues are fixed, I'll go ahead and close it too.

[Pil0tXia]

Thank you for your reply. I have removed good first issue and Hacktoberfest label exempt. You will get notified when assignees appear to be inactive.

I added weopen-star, GLCC, summer of code label to the exempt. These kinds of open source events go on for a long time. It should be nice now.

Change log:

• Close timer after stale message extended to 14 days

@xwm1992 @pandaapo @mxsm

I have updated this action. Now, the Stale Bot will not close any issues or pull requests. I prefer to have it simply provide reminders and guide contributors on how to advance their work with the help of the community.

In my opinion, the most effective way for reviewers to use the Stale Bot is to combine it with the mailing list. Comments sent by the Stale Bot in the issue@eventmesh.apache.org can be archived into a dedicated folder. Whenever this folder receives a new email, reviewers can check the corresponding pull request to see the progress.

I have added exclusion labels for issues that do not require comments from the Stale Bot.

Let me know your thoughts on this.

For the parameter days-before-pr-stale: 60, I set it to 60 because, apart from Dependabot's PR, there were 19 inactive PRs in the past 90 days, 20 inactive PRs in the past 60 days, and 21 inactive PRs in the past 30 days. Therefore, I feel that 60 is a reasonable value.

Days Before PR Stale	Number of Inactive PRs
90	19
60	20
30	21

For the parameter days-before-issue-stale: 90, I feel that 90 is a reasonable value:

Days Before Issue Stale	Number of Inactive Issues
120	152
90	155
60	160
30	174
