Harshavardhana 6a87ed001c Handle errors properly during erasure Decoding, also populate technique and verify 2015-03-24 18:14:13 -07:00
Harshavardhana 0474439b43 Code restructuring, assigning proper subsystems to each 
- Drivers contain
    * donut/*
    * file/*
    * memory/*

 - Storage format contains
    * donut/*
      - GetObject() --> renamed to GetObjectReader()
      - Deleted stale objectwriter.go, renamed donutwriter.go to object_writer.go

Simplifying, and documenting codebase further

Harshavardhana 596eeb097e Move from fmt.Errorf to errors.New 
In many cases fmt.Errorf is good enough, but since
error is an interface, you can use arbitrary data
structures as error values, to allow callers to
inspect the details of the error.

Harshavardhana e5af8a3f5d Further fixes - 
- All test files have been renamed to their respective <package>_test name,

        imports are largely used in testing, but to avoid namespace collision
        and circular dependencies

  - Never use _* in package names other than "_test" change fragment_v1 to expose
    fragment just like 'gopkg.in/check.v1'

This change brings in domain and subdomain support

   - ./minio --domain "yourminiodomain.com"

This change brings in a much needed feature by keeping
bucketnames as part of your 'DNS' name.

All your existing applications can be migrated off from s3 to
Minio without little to no modifications.

NOTE: Setting up DNS for your `buckets` is out of scope of this feature
