Harshavardhana ad1abc4486 xl-v1/Cleanup: use listOnlineDisks instead of getReadableDisks. (#1389)

to get the version list and extract higherVersion.

Harshavardhana 42254b5c4d xl: Rename blockingWriteCloser to waitCloser. (#1376) 2016-04-25 16:00:58 -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
