Re: Hob 1.2 design - Settings dialogue

I've added the reset option (restores the directories' default values) to
the Settings design document. The new version is at:

Hi Belen,

Sorry this is so long, I don't know how to turn off my verbose switch.

On page 4 you mention Shane's intention to have proxy settings in the
UI
- I just want to point out that this is usually an OS level
configuration and we should be wary about how we implement it.
I'd suggest we go so far as to just have a "Change system proxy
settings" button which launches the OS's network configuration
settings.

Of course, this opens us up to potential issues around supporting the
multitude of available network configuration tools on Linux but I'd
suggest we start with a lowest common denominator approach and have the
program behave intelligently.

Explicitly we can detect whether the binary gnome-control-center and
the
so file /usr/lib64/control-center-1/panels/libnetwork.so exist (being
clever about that path, too) and if so we can execute:

"gnome-control-center display network"

Which will display the network configuration (and therefore proxy)
settings for stock Fedora and Ubuntu desktops.
You guys are the experts. You tell me how you want it to work and I'll
design the UI for it! :)
My concern here was not to duplicate OS GUI to change OS settings, feels
to me that this is generally a bad idea. However I see from an
alternative thread that the intention is to only set the proxy
configuration for Yocto, if this is achievable through the site.conf I'm
all for it!

I understand why the Machines option might be more useful as a list
widget (p5), rather than a combo box, but feel that this is devalued at
least slightly by the fact that the list of available Machines isn't
static and therefore it's not unlikely a user would have to scroll that
list.
Yes, the list will scroll at some point. I am not too worried about it
though, since I don't think that changing the image types will be
something users will do very often. I might be wrong though.
I've made similar assumptions too, and as we don't have any data I'm in
no rush to disagree with either of us :-)

One suggestion might be to favour machines with a higher layer priority
by listing them higher in the list?
I donĀ¹t know how the layer priorities work. Who sets those priorities?
Are
they aligned with user's priorities? If they are, yes, we should use the
layer priorities to determine the order of that list of machines.
Layer priority currently is set by the layers author, but is editable by
the layers user (it's "just" a text file).

Maybe something to consider for future. There's been discussion about
making it easier to enable system users to alter the layer priority,
perhaps we'll make GUI changes if something like that happens? Or
perhaps we'll make the change for the sake of the GUI? More thought
required.

Although the next page, 5, mentions that the machine list is a combo
box. Is that the case?
It is the case in the Image configuration screen, where users, before
building an image, select their machine using a combo box. This screen
is
different from the Settings dialogue, where you set some BibBake output
and system variables (the image output types between them). This
document
in the wiki

http://wiki.yoctoproject.org/wiki/File:Hob_1.2_screens_inventory.pdf

might help making sense of the different screens.
Gotcha!

Love the package format selection pieces!

For the two parallel threads buttons we should recommend a default
value
and set a maximum based on the number of CPU cores - I think there's
been a lot of discussion about this but I'm not certain what the
recommendation which came out of it was.
That would be really useful. Is it easy to accurately determine how many
cores are supported by the CPU of the machine running Hob?
We can easily detect that, yes. The difficulty with enabling this kind
of feature in the past has been balancing between providing an accurate
recommendation and allowing the user to ignore it.

I wonder if this would be better as a feature for later to allow us more
time to get it right?


For the directories on page 13 would it make sense to have a reset
button to more easily get back to the defaults?
Yes, this probably makes sense. I'll add that to the document next week.
Great, thanks.

Joshua
