This commit introduces the ability to show previews for PRs by any author. It works as follows:
- The build artifacts of all PRs are uploaded to the preview server.
- Automatically verified PRs (i.e. from trusted authors or having a specific label) are deployed and
publicly accessible as usual.
- PRs that could not be automatically verified are stored for later use (after re-verification).
- A PR can be marked as "trusted" and make its preview publicly accessible by adding the GitHub
label specified in the `AIO_TRUSTED_PR_LABEL` env var of the preview server.
At the moment, there is no automatic mechanism for notifying the preview server about changes to the
PR's verification status. The PR's "visibility" will be checked and updated every time a new build
is uploaded.
Before 4f37f8643, we were using `innerText` to retrieved the code content for
copying. This preserved the text layout (including newlines), but suffered from
other issues (browser support, performance). With 4f37f8643 we switched to
`textContent`, which works well except in the following case:
When `prettify` formats the code to have line numbers, it removes the newlines
and uses `<li>` elements instead. This affects `textContent`.
This commit fixes this by keeping a reference of the code as text and using that
for copying.
Fixes#17659
We expect this behavior because it's what Travis does. Also it's better because we want
to test what happens if we merge the PR, not the status of the PR branch.
Running the patch script on Windows (with `patch` available) yields an invalid syntax warning, and does not apply patches.
