Progress on detailing section
This task is about taking a particular RPC an adding in more detail to create a 'gold standard' that can be used as a template in future.
+ settled on statfs as the detailed item. + Andrew understands this task as looking at what happens at the boundary conditions for RPC fields.
This is what Chris is expecting.
Andrew is expecting to provide a version of statfs for review in a day or two. For clarification, a further discussion of the error conditions when statting a file took place. The questions that should be considered include:
- when you try and stat a file, what happens when the file doesn't exist?
- what kinds of messages get sent when an error happens?
Sarp request progress milestones need to be shared so OpenSFS can
Richard said he would prepare suitable milestones for next weeks meeting.
