[webkit-dev] Announcing Login with GitHub on EWS webpages

[Aakash Jain]

Hi Everyone,

I am happy to announce that we expanded this feature and now any person with WebKit committer or reviewer privilege can also press "Stop" button on any ongoing EWS build. This is intended to be used in scenarios like:

- You got the required information from EWS (as some important EWS failed and you need to iteration on the PR/patch), and no longer need builds on other EWSes. (note that adding skip-ews GitHub label on the PR is another option to achieve similar thing)

- Cancelling any bad builds which seems to be stuck (e.g.: every api test timing out due to bug in PR/patch and test-run taking multiple hours)

- Trying to iterate over multiple versions of PR/patches for a particular platform, when you don't need builds on other platform for those iterations

- You don't need a specific EWS run and want to save EWS resources

Please use your own good judgement in deciding when to press that button.

Thanks
Aakash

Very small subset of our users (especially admins, bot-watchers etc.) actually need to login on build.webkit.org . On build.webkit.org, one common operation is to do "Force Clean build" (which does a clean build instead of incremental build). Any admin or WebKit reviewer can now login and perform that operation. If anyone feels like any other functionality needs to be exposed to wider audience, please let me know.

That way you could run EWS on specific queues.

>> Also, please note that the word 'Rebuild' and "Builder" comes from buildbot terminology, and might be little confusing for some of us, as we use terminology of "Builder" and "Tester" queues which means building WebKit and running tests. However, buildbot refers any queue as "Builder', and it refers retrying an EWS run as "Rebuild". Pressing "Rebuild" button on a tester queue (e.g.: webkitpy-ews) might not involve building WebKit or anything.

To login, on any ews buildbot page, simply click on "Anonymous" -> "Login with GitHub" (on top-right). You will need to authorize "WebKit EWS" to access your GtiHub account to Login.

>>> After login, any WebKit contributor (listed in https://github.com/orgs/WebKit/teams/contributors/members) can press "Rebuild" button on any build. This would provide ability to retry not just the failing builds, but any builds, including failed, cancelled, skipped or even successful builds (for example if last EWS run on a PR was many days back and you want to run EWS again). Please click on this button only when needed, as unnecessary retries might waste resources.

>>> If you are not listed in https://github.com/orgs/WebKit/teams/contributors/members and should have been listed there (e.g.: you are in contributors.json and have listed your GitHub account in it), please let me (or any WebKit admin) know.
