Inspect API

[prakashsvmx]

Inspect API ( mc admin inspect [--encrypt] <alias> <path> )

Steps to Test:

• With Encryption flag
  • .enc file will be generated along with a decryption key
  • use inspect tool and enter the decryption key to get the .zip file
  • use xl-meta tool to verify the contents of .zip file
• Without Encryption flag
  • use xl-meta tool to verify the contents of .zip file.

API URL : /api/v1/admin/inspect?file=test.txt%2Fxl.meta&volume=test-bucket&encrypt=true

When I reach an invalid path (invalid bucket or objects) , I get status response 200 instead of 404

The API is not designed to get 404 it's expected to see failures since it's a "debugging" API - Do not think of it like S3 API as it is allowed to download any path any file in its RAW form.

Like you can download

• alias/.minio.sys/format.json
• alias/.minio.sys/** (recursively download all .minio.sys data from all nodes all drives)
• alias/bucket/path/** (recursively download all xl.meta, part.1 data from all nodes all drives)
• alias/bucket/path/object/* (just download files at the path - non-recursive but all files at this path)
• alias/bucket/path/object//part.1 (download just part.1 for a specific object data-dir at uuid)

The response is a Zip stream, so failures are allowed and normal.

The UI should be designed to support these requirements
