feat(storage): Improve error messages

Current `errorToStatus` is not displaying the underlying error if the status code is 400. Additionally, we are sending the error into this function twice: Once in the error message and again in the error itself. This commit changes the way `errorToStatus` works by sending a message indicating where the error occured and then the actual error as a different argument. Additionally, it changes `errorToStatus` to always print the input message and the error regardless of error type.

Hugo	7d2654e707	feat(storage): Improve error messages Current `errorToStatus` is not displaying the underlying error if the status code is 400. Additionally, we are sending the error into this function twice: Once in the error message and again in the error itself. This commit changes the way `errorToStatus` works by sending a message indicating where the error occured and then the actual error as a different argument. Additionally, it changes `errorToStatus` to always print the input message and the error regardless of error type.	2024-10-01 15:13:57 +01:00
Hugo	759ac083ac	feat(storage): Drop checksum headers Some non-MinIO services that can use this plugin do not support `x-amz-checksum-algorithm` and/or `x-amz-checksum-sha256`. Important to note that if a SHA256 checksum still comes through in the response, the existing code will verify that it matches what we have locally.	2024-10-01 15:13:57 +01:00

If the error is a permission related error, convert the error to a `Permission` proto and attach it to the gRPC status - Update `dryRun` method to join all errors before returning response. This ensures all the permissions are validated before returning * refactor errorToStatus to return storage states * update oncreate and validate errorcodes on failure * update go.mod for new sdk version * update tests to parse state instead of permissions --------- Co-authored-by: Elim Tsiagbey <elim.tsiagbey@hashicorp.com>	2024-07-17 15:37:45 -04:00
Hugo	caa6c4eda2	feat(storage): Make checksum verification optional Some 3rd party services the MinIO SDK can connect with do not return a checksum whenever a file is uploaded. Before this change, this would lead to an error, rendering it impossible to operate with those 3rd party services. With this change, we'll continue to verify checksums if they come through, however we won't error out if they don't and the PutObject call is successful. Note: There are no new tests with this change as this behaviour is not unit-testeable at the moment. I suggest we could have end-to-end tests for this.	2024-06-10 16:19:20 +01:00
