Yes. However, cancelled context is currently treated as a special case everywhere else that checks for expected errors (eg. here and here), so this PR makes reading an object consistent with that. We could remove all the special checks for context cancellation, but that would then be a change in current behaviour for all consumers of this library. |

Isn't this actually hiding an error? If the initial s3 read that we do to check for 404 fails because of connection issue we don't get timing or error metrics |

This PR fixes an issue where the
objstore_bucket_operation_failures_totalmetric is incremented if the context is cancelled while reading an object from a bucket but after theGetorGetRangemethod has returned.This makes the behaviour consistent with other operations, and makes the behaviour consistent with a cancellation that occurs while
GetorGetRangeis executing.Verification
I have added unit tests to cover this scenario.
