Subject: [PATCH 156/169] cloudsync: Fix bug in cloudsync-fops-c.py
|
|
|
14f8ab |
|
|
|
14f8ab |
In some of the fops generated by generator.py, xdata request
|
|
|
14f8ab |
was not being wound to the child xlator correctly.
|
|
|
14f8ab |
|
|
|
14f8ab |
This was happening because when though the logic in
|
|
|
14f8ab |
cloudsync-fops-c.py was correct, generator.py was generating
|
|
|
14f8ab |
a resultant code that omits this logic.
|
|
|
14f8ab |
|
|
|
14f8ab |
Made changes in cloudsync-fops-c.py so that correct code is
|
|
|
14f8ab |
produced.
