Ignore name of index when fetching settings #823

Description

This commit fixes a situation where an index cannot be updated through this client as the index is aliased, with the client pointing to the alias.

As the GET /<index>/_settings request will only ever return the settings for the specified index (through the alias), it would only have one key, so the name of the key would not matter. We can pop the key to get the settings object for the index through the alias.

Describe what this change achieves.

What's the value of _name vs. what it is after the change here?
Can you please add a test?

Thank you @dblock for your quick response! The value of removing self._name is that saving an index previously wouldn't work if OS-py accesses it through an alias (and using an alias seems to be a good practice for downtime prevention). All the requests that are triggered by the .save() method can work transparently through an index, however, when making the GET /<alias>/_settings request, the dict response key is the name of the true index, rather than the alias. This causes the KeyError. However, the data we're extracting doesn't depend on the name, so it'd be safe to disregard and pop the key/value.

If it's wanted, I could add a check that the alias only points to one index to raise a more specific error. Would that be appreciated?

I've added a test, but I'm a little skeptical of the coverage report as it's based off a 6-month-old commit.

Thank you!

Possibly, but doesn't have to block this PR. Give it a shot after I merge this!

This all makes sense.

I think you have to do the same for the async code (see https://github.com/opensearch-project/opensearch-py/blob/main/opensearchpy/_async/helpers/index.py#L308). Add a test for that too.

I've added support for async, the checks for multiple indices, and testing for these.

Looks good!

I have some small language asks for the error. Also check that the tests do run because CodeCov seems unhappy and complains that tests are missing which seems odd.

What's the reason for this change? AFAIK it should always be https.

Oh sorry, didn't mean to commit that! I had noticed that the tests did not run, and had to uncomment these list values to get the tests to run:

ignores = [
"test_opensearchpy/test_server/",
"test_opensearchpy/test_server_secured/",
"test_opensearchpy/test_async/test_server/",
"test_opensearchpy/test_async/test_server_secured/",
]

I am a little hesitant to commit such changes as I don't have much context as to why this has been done and if it'd break anything. Also, the base commit for Codecov is quite old.

Ugh this looks like a mess. I opened #826 with a high level idea of what we should do here (maybe someone wants to help later, wink wink).

For this PR I'd like to ensure the tests you wrote actually run (and pass) in CI. Is this the case?

The tests do pass locally with the files un-ignored (although this assertion is somewhat empty)

On GitHub Actions they would be skipped as there is no OpenSearch service for the tests to use.

That's the whole point, integration tests should run on GHA in one of the workflows.

@tienne-B so we can't merge this without a passing CI, help out with whatever the right answer is to get it to pass and ensuring that the tests you have added do run in CI, please?

I debugged the test failure but couldn't find a solution. You can rebase with the workaround in #828 for now (or maybe you know how to fix that failure?).
