Bala.FA c70bc2209e api: refactor list object handling in fs backend
When list object is invoked, it creates a goroutine if not available
for given parameters else uses existing goroutine.  These goroutines
are alive for 15 seconds for further continuation list object request
else they exit.

Fixes #1076

Brendan Ashworth 0a0451a0fb pkg/fs: DRY SetBucketMetadata
It had a lot of code that was the same as GetBucketMetadata, so instead
call GBM from SBM so as to reduce doing the same thing in two different
spots. Theoretically this will induce a small overhead as now at least
two calls of denormalizeBucket are made, although this shouldn't be
noticeable.

Brendan Ashworth 294ea814bf pkg/fs: for locks, prefer defer and read-only ops
This commit prefers the use of 'defer' for fs.Unlock (and fs.RUnlock)
because it is more idiomatic Go and reduces repetition in the code,
lending to a cleaner code base.

It also switches a few uses of the lock to read-only locks, which should
improve performance of those functions dramatically in certain contexts.

Harshavardhana aed62788d9 api: Implement multiple objects Delete api - fixes #956
This API takes input XML input in following form.

```
<?xml version="1.0" encoding="UTF-8"?>
<Delete>
    <Quiet>true</Quiet>
    <Object>
         <Key>Key</Key>
    </Object>
    <Object>
         <Key>Key</Key>
    </Object>
    ...
</Delete>
```

and responds the list of successful deletes, list of errors
for all the deleted objects.

```
<?xml version="1.0" encoding="UTF-8"?>
<DeleteResult xmlns="http://s3.amazonaws.com/doc/2006-03-01/">

Harshavardhana 0aedb67de0 contentType: Reply back proper contentTypes based on the file extension.
Currently the server would set 'application/octet-stream' for all
objects, set this value based on the file extension transparently.

This is useful in case of minio browser to facilitate displaying
proper icons for the different mime data types.

Harshavardhana 2469c9c591 presign: Verify query params for presign individually
Incoming request params in presigned can come in different order
for different implementations. Rather than verifying a full string
we should verify individual params instead.

This patch fixes an incompatibility issue with AWS SDK Java.

Harshavardhana 5934a00058 listObjects: ListObjects should have idempotent behavior.
listObjects was returning inconsistent results, i.e missing
entries during recursive and non-recursive listing. This led
to 'mc mirror' copying contents repeatedly consisdering
these files to be missing on the destination.

This patch addresses this problem - fixes #1056

Harshavardhana db387912f2 jwt: Deprecate RSA usage, use HMAC instead.
HMAC is a much simpler implementation, providing the same
benefits as RSA, avoids additional steps and keeps the code
simpler.

This patch also additionally

- Implements PutObjectURL API.
- GetObjectURL, PutObjectURL take TargetHost as another
  argument for generating URL's for proper target destination.
- Adds experimental TLS support for JSON RPC calls.

Harshavardhana 9ca3372870 listObjects: Marker should be unescaped before being used internally.
Without this change listObjects() goes into an infinite loop for
files which have special characters i.e "++" encoded with "%2B%2B".

We have to unescape and convert them to their native representation
before being used internally.

Harshavardhana 5d87fdb35c Merge pull request #1051 from harshavardhana/fix-multipart
multipart: NewMultipartUpload shouldn't return empty UploadID
2016-01-26 15:15:44 -08:00
Harshavardhana 2e311168ee multipart: NewMultipartUpload shouldn't return empty UploadID
Existing code
```
{
  if os.IsNotExist(e) {
       e = os.MkdirAll(objectDir, 0700)
       if e != nil {
            return "", probe.NewError(e)
       }
  }
  return "", probe.NewError(e)  ---> Error was here.
}
```
For a successful 'MkdirAll' it would still return an empty uploadID,
but the 'error' would be nil. This would succeed the request but
client would fail.

Fix is to re-arrange the logic. Thanks to Alexander Neumann @fd0, for
reporting this problem.

Harshavardhana 8cdaf87c8f signature: Add aws-cli work-around for now.
Golang http server strips off 'Expect' header, if the
client sent this as part of signed headers we need to
handle otherwise we would see a signature mismatch.
`aws-cli` sets this as part of signed headers which is
a bad idea since servers trying to implement AWS

Signature version '4' will all encounter this issue.
According to
 http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.20
Expect header is always of form:

   Expect       =  "Expect" ":" 1#expectation
   expectation  =  "100-continue" | expectation-extension

So it safe to assume that '100-continue' is what would
be sent, for the time being keep this work around.
