This is meant to reflect the RPC's comment verbatim. If I change it here, we'll need to update the protos as well.

Is this PR checking in generated code? I'm not sure we need to reflect the RPC's comment verbatim (though, yes, it should be changed there too.)

The delta here is nearly identical to the generated code, so yes. I'm adding it in this way (as opposed to copy-pasting the new GAPIC client entirely) to preserve existing manual changes and ensure that dependencies won't break.

Updated the comment.

this looks testable

This is a direct import of the generated GAPIC surface for the Wait* portion of the LRO proto, so none of the *Settings() getters in this file are tested (as is the case in all the generated GAPIC libraries).

I'm trying to understand whether you're proposing re-generating code in the future. That's not longterm maintainable. There are two paths that can work. Either the code is generated every time when the project is compiled, with the generated code never checked into the repo (the protobuf approach) or it's generated once, checked into the repo, and then manually edited for ever after. Anything in between makes maintenance extremely difficult. Which path is this PR proposing?

Ping. This is a critical issue.

This PR (and others in this repo) only updates the LRO client with the auto-generated section for Wait, and does not propose a particular path. While the long-term path is not clear yet, keeping this client as consistent as possible with the generated code will make debugging less error prone and make updates easier, while we figure this out.

Autogenerated or no., I still think a test helps here. If the autogenerated code chages in a way that causes the test to fail, the test will make that apparent.

I've filed #1299 to track this, since adding tests for this method is essentially equivalent to setting up tests for all the settings getters, which is beyond the scope of this PR.

This is a great point, and I'll look into whether we can add such autogenerated tests to gapic-generator-java.

I still think there should be a test of this method.

As above - tracked in #1299, will investigate this feature for gapic-generator-java.

@Override

I don't think there's a corresponding method in BackgroundResource? Unless you meant that the @Override should be added to GrpcOperationsStub, in which case, done.

Also, I'll be adding this to the GAPIC generation, so this will be consistent with a future generated surface.

This is very strange. The response can have multiple types?

Copied verbatim from the standard generated GAPIC library for the LRO proto, as are the methods above.

Would prefer to keep this as close to the auto-generated code as possible, so that manual, semantic-impacting changes can be easily identified if this LRO GAPIC ever needs to be regenerated.

LGTM, but I'm wondering how the code was created for this PR (generated, manually or generated+manually).

A question about all of the changes in this PR: are these chagnes were added manually or generated, or some sort of "generated and then manually postprocessed"?
