Hi! Static analysis pointed out a few places with potential errors so maybe you will be interested in changes I did:

  • check if frame is nullptr before frame->Submit(); (there is a similar check on the next lines)
  • initialize last_baton_ (it is used but never initialized)
  • initialize client_id_ (it is set in another method but I believe it should be initialized)

Pre-launch Checklist

  • I read the Contributor Guide and followed the process outlined there for submitting PRs.
  • I read the Tree Hygiene wiki page, which explains my responsibilities.
  • I read and followed the Flutter Style Guide and the C++, Objective-C, Java style guides.
  • I listed at least one issue that this PR fixes in the description above.
  • I added new tests to check the change I am making or feature I am adding, or Hixie said the PR is test-exempt. See testing the engine for instructions on
    writing and running engine tests.
  • I updated/added relevant documentation (doc comments with ///).
  • I signed the CLA.
  • All existing and new tests are passing.

If you need help, consider asking for advice on the #hackers-new channel on Discord.

It looks like this pull request may not have tests. Please make sure to add tests before merging. If you need an exemption to this rule, contact Hixie on the #hackers channel in Chat.

If you are not sure if you need tests, consider this rule of thumb: the purpose of a test is to make sure someone doesn't accidentally revert the fix. Ask yourself, is there anything in your PR that you feel it is important we not accidentally revert back to how it was before your fix?

Reviewers: Read the Tree Hygiene page and make sure this patch meets those guidelines before LGTMing.

The comments about default initializing the values in the header are nits. But bumping the submitted frame count when there is no frame must be addressed however.

If the frame pointer is null (checked later), there must be an early return so the submitted frame count in not bumped up.

So something like.

if (!frame) {
  return;
}

followed by the removal of frame && later on like 70 since that check will now be redundant.

Good call. But, consider defaulting it in the header in case another ctor is added later. Something like uint64_t last_baton_ = 0; in embedder_task_runner.h.

Nit but ditto about defaulting in the header.

Unfortunately, this needs to be rebased on ToT for the presubmits to pass. Can you please do the same so I may add the CQ tag?

There is a check on line 70 if frame is nullptr so probably it should be also checked before frame->Submit().
