- How will all the targets in TI be created? By using the

Or create all the targets directly using Python?
If we do use libti.so it will be through ctypes but the plan is to
create all the targets using Python.
OK. In this case, then, I think it would be useful to discuss how
you are
planning to go about creating the targets using Python. Are you
going to call
commands via Python, or are you going to use some Python APIs
from some components? If I remember correctly, ZFS has some Python
interfaces.
Whatever you decide to do, I think it should be documented.
We both think this is an implementation detail and shouldn't be in a
design doc.
Personally, I don't think of this as an implementation detail.
Whether Python will be
calling a command or some other Python API provided by another project
are all
imported interfaces, and I think they should be listed in the design doc.
After talking with you on the phone I understand more what you want.
We'll put in the
doc the info that as to what projects we'll be using (fdisk, zfs etc)
and what type of interfaces we
are expecting to use (cli, python).
* Section 8.2:
- It's not clear to me where these destroy data object and create
data object
live in the DOC tree?
The live in the checkpoint node for TI.
The checkpoint node for TI... When will the checkpoint node for TI
be created, and
who creates that?
The application creates all checkpoint nodes, right?
I guess that depends on the application. I don't see why an
application need
to create any checkpoint nodes. Are you saying that in order to pass
in the
the tree of objects for TI to create, an application is required to
create the TI checkpoint node?
Yes. I believe we agreed on the phone that the application would be
creating a DOC node with the create
object in it to pass to TI.
Thanks,
Jean
