Optimizing List Objects by using binary sort to discard entries in cases
where prefix or marker is set.
Adding test coverage to ListObjects.
Adding benchmark to ListObjects.
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'.
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.
Fixes#1076
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.
There is now a simple test and a benchmark for ListBuckets. I also
dropped an unnecessary check that was simply repeated from above,
guaranteed to be true.
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.
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.
This API takes input XML input in following form.
```
<?xml version="1.0" encoding="UTF-8"?>
<Delete>
<Quiet>true</Quiet>
<Object>
<Key>Key</Key>
</Object>
<Object>
<Key>Key</Key>
</Object>
...
</Delete>
```
and responds the list of successful deletes, list of errors
for all the deleted objects.
```
<?xml version="1.0" encoding="UTF-8"?>
<DeleteResult xmlns="http://s3.amazonaws.com/doc/2006-03-01/">
<Deleted>
<Key>sample1.txt</Key>
</Deleted>
<Error>
<Key>sample2.txt</Key>
<Code>AccessDenied</Code>
<Message>Access Denied</Message>
</Error>
</DeleteResult>
```
Golang 1.6 is default version for the build now.
Additionally set 'GODEBUG=cgocheck=0' for now, until
we fix the erasure coding package.

- Move fs-definitions.go and break them into fs-datatypes.go, fs-bucket-acl.go
and fs-utils.go
- Move api-definitions.go to api-response.go, where they should be.
- Move web-definitions to its related handlers.
Minor optimization.
- Add 1000 entries buffered channel for walkerCh.
- Reset marker after the lexical order has reached and
compare only if the marker is set.
- Fixes initiating parallel uploads, and configs being quickly
re-written by another incoming request.
- Parallel uploads work smoothly now and return expected behavior.
