CopyObjectHandler() was incorrectly performing comparison
between destination and source object paths, which sometimes
leads to a lock race. This PR simplifies comparaison and add
one test case.
We can't use Content-Encoding to verify if `aws-chunked` is set
or not. Just use 'streaming' signature header instead.
While this is considered mandatory, on the contrary aws-sdk-java
doesn't set this value
http://docs.aws.amazon.com/AmazonS3/latest/API/sigv4-streaming.html
```
Set the value to aws-chunked.
```
We will relax it and behave appropriately. Also this PR supports
saving custom encoding after trimming off the `aws-chunked`
parameter.
Fixes#3983
startOffset was re-assigned to '0' so it would end up
copying wrong content ignoring the requested startOffset.
This also fixes the corruption issue we observed while
using docker registry.
Fixes https://github.com/docker/distribution/issues/2205
Also fixes#3842 - incorrect routing.
The globalMaxObjectSize limit is instilled in S3 spec perhaps
due to certain limitations on S3 infrastructure. For minio we
don't have such limitations and we can stream a larger file
instead.
So we are going to bump this limit to 16GiB.
Fixes#3825
Content-Encoding is set to "aws-chunked" which is an S3 specific
API value which is no meaning for an object. This is how S3
behaves as well for a streaming signature uploaded object.
This is written so that to simplify our handler code
and provide a way to only update metadata instead of
the data when source and destination in CopyObject
request are same.
Fixes#3316
* Refactor streaming signatureV4 w/ state machine
- Used state machine to make transitions between reading chunk header,
chunk data and trailer explicit.
* debug: add print/panic statements to gather more info on CI failure
* Persist lastChunk status between Read() on ChunkReader
... remove panic() which was added as interim aid for debugging.
* Add unit-tests to cover v4 streaming signature
- Cleaning up of ListMultipartUpload API test for improving readability,
code maintainance and extensibility.
- Moving ListMultipartUploads to Go 1.7 sub tests.
- Using the new Anonymous request helper function for
ListMultipartUploads.
- Add helper function for API handler anonymous request tests.
- Add PutObject Part Anonymous request case using the new helper
function to validate its functionality.
- Clean up PutObjectPart and ListObjectPart API handler tests.
- Add more comments, make the tests more readable.
- Add verification for HTTP response status code.
- Initialize the test using object Layer.
- Move to Go 1.7 sub tests.
* Add missing uploadID test
... make variables in test code unexported.
* Add ServerNotInitialized test for ListObjectPartsHandler
* Add tests for ListObjectParts with signatureV2 and Anonymous requests
* Add failure test cases for ListObjectParts
* api/complete-multipart: tests and simplification.
- Removing the logic of sending white space characters.
- Fix for incorrect HTTP response status for certain cases.
- Tests for New Multipart Upload and Complete Multipart Upload.
