#### Method Patch
|
||||
|
||||
Patch the object. Request uses gRPC stream. First message must set
|
||||
the address of the object that is going to get patched. If the object's attributes
|
||||
are patched, then these attrubutes must be set only within the first stream message.
|
||||
|
||||
If the patch request is performed by NOT the object's owner but if the actor has the permission
|
||||
to perform the patch, then `OwnerID` of the object is changed. In this case the object's owner
|
||||
loses the object's ownership after the patch request is successfully done.
|
||||
|
||||
As objects are content-addressable the patching causes new object ID generation for the patched object.
|
||||
This object id is set witihn `PatchResponse`. But the object id may remain unchanged in such cases:
|
||||
1. The chunk of the applying patch contains the same value as the object's payload within the same range;
|
||||
2. The patch that reverts the changes applied by preceding patch;
|
||||
3. The application of the same patches for the object a few times.
|
||||
|
||||
Extended headers can change `Patch` behaviour:
