Previously, the preview server would incorrectly identify a running
`aio_preview` CI job as failed and therefore skip creating a preview.
This happened because it only checked whether the job's status is
`success`, failing to account for the fact that the job would have a
`running` status.
(This bug was accidentally introduced in #45934.)
This commit avoids the problem by getting rid of the job status check
altogether. This check does not offer any benefit, since the CI job will
always be in a `running` state (i.e. neither successfully completed nor
failed).
PR Close#45948
Previously, Travis pushed the build artitfacts to the preview server.
This required us to use JWT to secure the POST request from Travis, to
ensure we couldn't receive malicious builds.
JWT has been deprecated and we are moving our builds to CircleCI.
This commit rewrites the TypeScript part of the preview server that
handles converting build artifact into hosted previews of the docs.
This commit adds an API endpoint for notifying the preview server about PR
updates (`/pr-updated`). According to the update, the preview server can take
several actions. Currently, it will only check and (if necessary) update the
PR's preview visibility (but more actions could be supported in the future).
The API can be used with an automatic trigger (e.g. a GitHub webhook) to
instantly update a PR's preview visibility when it changes.
Fixes#16526
