Idle It should be return Request Response like this e.g. :

Sample Request

This requests returns the objects in BucketName.

HEAD / HTTP/1.1
Date: Fri, 10 Feb 2012 21:34:55 GMT
Authorization: authorization string
Host: myawsbucket.s3.amazonaws.com
Connection: Keep-Alive
Sample Response

HTTP/1.1 200 OK
x-amz-id-2: JuKZqmXuiwFeDQxhD7M8KtsKobSzWA1QEjLbTMTagkKdBX2z7Il/jGhDeJ3j6s80
x-amz-request-id: 32FE2CEB32F5EE25
Date: Fri, 10 2012 21:34:56 GMT
Server: AmazonS3

But here for LeoFS Response header doen't return object name or 200 OK.
it gives headers like this(404 Not Found) :

HEAD / HTTP/1.1
Host: test.localhost:8080
User-Agent: aws-sdk-php2/2.6.0 Guzzle/3.8.1 curl/7.19.7 PHP/5.3.3
Date: Mon, 14 Apr 2014 07:22:34 +0000
Authorization: AWS 05236:mEfYFW7i3tudc0yhuyYMTC2Q16s=

HTTP/1.1 404 Not Found
connection: keep-alive
date: Mon, 14 Apr 2014 07:22:34 GMT
content-length: 0
server: LeoFS

Due to this response above all methods are not working.

Hi @Paras2009.
I've fixed this issue just now with this commit(leo-project/leo_gateway@88a28d5).
Please confirm with the latest develop branches?

[rr-paras-patel]

Hi i have confirmed this updated. It is working fine.

[yosukehara]

Thank you so much 👍

[rr-paras-patel]

I want to reopen this issue.

[yosukehara]

@patelparas What's happen in your environment. Let me know the detail.

[rr-paras-patel]

doesBucketExist() method always return 'true'.
Whether bucket exist or don't exist.

[mocchira]

@patelparas please tell me which version of aws-sdk-php you are using?

[rr-paras-patel]

my aws-sdk-php version is 2.7.5.

[mocchira]

@patelparas Thanks.
I could reproduce your issue and almost found out why this happen.
please wait for a while.

[mocchira]

LeoFS have responded 403 status when the requested bucket doesn't exist,
but sdk expect 404.

We need to respond as below.

ErrorCode: NoSuchBucket
Description: The specified bucket does not exist
HTTP Status: 404

[mocchira]

@patelparas I found that
http://docs.aws.amazon.com/aws-sdk-php/v2/api/class-Aws.S3.S3Client.html#_doesBucketExist
this method can handle 403 as a NOT FOUND by setting the second argument to false.
So the below test code have passed.

leo-project/leofs_client_tests@61add23

If this works for you, we will close this issue.

[rr-paras-patel]

ok i will check it. Thank you

[mocchira]

I found that head_bucket occasionally fails after creating bucket successfully.
So I gonna look into this issue again.

[mocchira]

found out why.
