Karthic Rao 99af0444b7 Handling maxKeys=0 case with a empty response 2016-03-18 15:16:30 +05:30
Harshavardhana 88714e7c8e bucketpolicy: Improve bucket policy validation, avoid nested rules.
Bucket policy validation is more stricter now, to avoid nested
rules. The reason to do this is keep the rules simpler and more
meaningful avoiding conflicts.

This patch implements stricter checks.

Example policy to be generally avoided.

Brendan Ashworth 583e4ecff6 pkg/fs: optimize GetObject syscalls for common case
In the common case, GetObject is called on a bucket that exists and an
object that exists and is not a directory. It should be optimized for
this case, thus error-related syscalls are pushed back until they are
necessary.

This should not impact performance negatively in the uncommon case, and
instead drops two otherwise unnecessary os.Stat's in the common case.

The race conditions around a proper error being returned were present
beforehand.

It also renames 'err' to 'e'.

Brendan Ashworth b2257682e4 pkg/fs: add benchmark for GetObject
This commit adds a benchmark for GetObject. It doesn't leverage the I/O
as much because it uses short text for data, just 58 chars.

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.

Brendan Ashworth cd3eb63c4a pkg/fs: test, document, and fix IsValid{Bucket,Object}Name
This commit improves the docs for both functions (more Go-like) and
drops an unnecessary condition in IsValidBucketName. This also drops a
condition in IsValidObjectName where "" (empty string) was a valid
object name. This has been fixed and will no longer return true.

This commit also adds tests for both functions, including a regression
test for the bug fix.

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.

for all the deleted objects.
