Harshavardhana	1d8a8c63db	Simplify data verification with HashReader. (#5071) ... Verify() was being called by caller after the data has been successfully read after io.EOF. This disconnection opens a race under concurrent access to such an object. Verification is not necessary outside of Read() call, we can simply just do checksum verification right inside Read() call at io.EOF. This approach simplifies the usage.	2017-10-22 11:00:34 +05:30
Harshavardhana	d3eb5815d9	Avoid DDOS in PutObject() when objectName is '/' and size '0' (#4962) ... It can happen that an incoming PutObject() request might have inputs of following form eg:- - bucketName is 'testbucket' - objectName is '/' bucketName exists and was previously created but there are no other objects in this bucket. In a situation like this parentDirIsObject() goes into an infinite loop. Verifying that if '/' is an object fails on both backends but the resulting `path.Dir('/')` returns `'/'` this causes the closure to loop onto itself. Fixes #4940	2017-09-25 14:47:58 -07:00
