Harshavardhana 00c697393a Merge pull request #1381 from minio/xl-layer 
Implement XL layer
 2016-04-25 15:59:30 -07:00
Harshavardhana 55032ffdf9 xl: Simplify blockingWriter and its usage. (#1373) 
This removes odd races since we don't need to
track errors and avoids locking. All we need
is a Wait() and Done() waitgroup.

Harshavardhana 8bce699dae xl: Add logging. (#1372) 2016-04-25 12:47:31 -07:00
Harshavardhana 57f35c2bcc xl: Introduce new blocking writer to make CreateFile atomic. (#1362) 
Creates a new write closer that must be released
by the read consumer. This is necessary so that
while commiting the underlying writers in erasure
coding we need to make sure we reply success only if
we have committed to disk.

This in turn also fixes plethora of bugs related to
subsequent PutObject() races with namespace locking.

This patch also enables most of the tests, other than
ListObjects paging which has some issues still.

Fixes #1358, #1360

Krishna Srinivas becc814531 Xl layer selfheal quorum2 
* xl/selfheal: selfheal based on read quorum on GET

* xl: getReadableDisks() also returns whether self-heal is needed so that this info can be used by ReadFile/SelfHeal/StatFile.

* xl: trigger selfheal from StatFile.

Harshavardhana bf8a9702a4 tests: Fix a bug in TestObjectAPIIsUploadIDExists. (#1375) 
The following code crashes when upload ID does not
exist, since we are setting err == nil when we find
err == errFileNotFound.

```
if e == nil {
   t.Fatal(e.Error())
```

Fix it.

Harshavardhana 4cf73caf02 api: Add diskInfo as part of StatVol and ListVols. (#1349) 
It is the bucket and volumes which needs to have this
value rather than the DiskInfo API itself. Eventually
this can be extended to show disk usage per
Buckets/Volumes whenever we have that functionality.

For now since buckets/volumes are thinly provisioned
this is the right approach.

Bala FA bea6f33b08 backend/fs: remove timer channel from scanMultipartDir() (#1310) 
Previously scanMultipartDir() returns object info channel and timer
channel where timer channel is used to check whether object info
channel is alive or not.  This causes a race condition that timeout
may occur while object info channel in use.

This patch fixes the issue by removing timer channel and uses object
info channel directly where each object info has End bool field
indicates whether received object info is end or not.
