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>
```
This commit makes code cleaner and reduces the repetitions in the code
base. Specifically, it reduces the clutter in setObjectHeaders. It also
merges encodeSuccessResponse and encodeErrorResponse together because
they served no purpose differently. Finally, it adds a simple test for
generateRequestID.
