Harshavardhana 6266328a85 XL/metadata: use new hashOrder algorithm for newXLMeta. (#2147) 2016-07-08 15:39:21 -07:00
Harshavardhana ca1b1921c4 XL: Implement ignore errors. (#2136)
Each metadata ops have a list of errors which can be
ignored, this is essentially needed when

  - disks are not found
  - disks are found but cannot be accessed (permission denied)
  - disks are there but fresh disks were added

This is needed since we don't have healing code in place where
it would have healed the fresh disks added.

Fixes #2072

Harshavardhana 8a028a9efb handler/PUT: Handle signature verification through a custom reader. (#2066)
Change brings in a new signVerifyReader which provides a io.Reader
compatible reader, additionally implements Verify() function.

Verify() function validates the signature present in the incoming
request. This approach is choosen to avoid complexities involved
in using io.Pipe().

Thanks to Krishna for his inputs on this.

Harshavardhana 734e779b19 XL/erasureCreate: Create a limit reader if size is specified. (#2059)
This is needed so that we only write data which was requested
for, using a limit reader avoids spurious reads on the incoming
client data. Additionally using limit reader provides server
safety from rogue clients sending copious amounts of data (for
example a denial of service attack).

This patch also caters for size == -1 when content encoding from
a client is set as chunked, we happily read till io.EOF

Krishnan Parthasarathi 64899e5197 xl: Used unique tmp file to update xl.json in putObjectPart (#2043)
An in-place update to xl.json amidst concurrent PutObjectPart operations
lead to racy updates to xl.json making it un-parseable. To avoid this,
we create a unique tmp file where updates to xl.json are staged before
renaming it to the final location.
