[PATCH 1/7] Hob: Fix MACHINE setting

[Dongxiao Xu]

Define the empty curr_mach to be "" instead of None.
Fix the judgement for ' if self.curr_mach == "" ' to be
' if self.curr_mach '.
Also set machine to bitbake server when "MACHINE" is not empty.

[PATCH 3/7] Hob: Make layers define in bblayers.conf as default

[Dongxiao Xu]

For layers defined in bblayers.conf, we treat them as default layers
and users are not allowed to remove them.

Can you explain the rationale behind this change? I see what you're 
doing but it's not entirely clear why.

I think this is a bad idea. Early on in the design of Hob we decided we 
didn't want configuration made for non-Hob builds to affect builds made 
with Hob, and vice versa.

Thanks,
Joshua

The issue I am going to solve is that, with current local.conf
(DISTRO="poky") and bblayers.conf (bblayers="meta meta-yocto"), we are
not able to delete the meta-yocto layer in Hob since it will meet
local.conf parsing error since it could not find where "poky" is
defined.

This patch is to set those layers define in bblayers.conf as default
layers and they could not be removed. For example, in Yocto Project,
"meta", "meta-yocto", and "meta-hob" are not removable. For pure OE-Core
environment, "meta" and "meta-hob" are not removable.

Thanks,
Dongxiao

Just discussed with Josh on this problem.

He suggested that meta-yocto should be still removable. If user met the
error after deleting the meta-yocto layer, he/she should change the
DISTRO setting in "Setting" dialog to "defaultsetup".

Current code to handle the distro setting is:

    def set_distro(self, distro):  
        if distro != "defaultsetup":   
            self.server.runCommand(["setVariable", "DISTRO", distro])

Therefore even if user has selected defaultsetup, it will not set any
value to bitbake server, and then DISTRO ?= "poky" will take effect
while parsing local.conf.

To make DISTRO ?= "poky" doesn't take effect, we need to change the code
to be:

    def set_distro(self, distro):  
        if distro == "defaultsetup":   
            distro = ""
        self.server.runCommand(["setVariable", "DISTRO", distro])

However Richard ever worried about this approach.
See:
http://lists.linuxtogo.org/pipermail/bitbake-devel/2012-March/002438.html

In summary, there are two solutions now:

1) Set those layers defined in bblayers.conf as default, and don't allow
users to delete them, like this [PATCH 3/7] does.
2) Use the empty string "" as the value of DISTRO variable for
"defaultsetup", and set this value before parsing configuration files,
making the DISTRO ?= "poky" in local.conf doesn't take effect.

Welcome for comments on this issue.

I'd be happy if you change the above code to do:

        self.server.runCommand(["deleteVariable", "DISTRO"])

which is subtly different but consistent with what we really want. I
have no idea if we have a deleteVariable command but if we don't, we
should add one.

Richard

I ever tried this approach with the following patch, however it didn't
work. The setting of DISTRO ?= "poky" will still take effect.

It seems that delVar(DISTRO) is different from setting DISTRO="".

It is different but it is what setting up OE-Core without DISTRO set
does and that is known to work.

We need to understand why this isn't working as it should...

Thinking more about this, I think I can see a pattern in the issues I'm
seeing patches for from you and Shane.

I think you have things setup such that you do:

a) Set variables
b) Parse configuration

And the problem is that if anywhere in the configuration, something like
A = "B" happens, the value of A is overridden if you set it in A. This
also would apply if you run delVar, then the code does a ?= since it
will get reset.

The trouble is you have to do this since you need to set MACHINE and
DISTRO in advance.

I'm starting to think you may have to have hob have its own empty
"local.conf" which overrides the user provided one. You would parse the
user's local.conf separately and extract any settings into hob as needed
though (pass through all values except the ones you know need specific
values from the UI).

Its ugly but I can't see any better way to handle this situation that
will make sense to the user and give the correct user experience. As I
said to Shane elsewhere, we cannot force the local.conf file to be
written in a certain way, just to suit the requirements of hob.

Cheers,

Richard

I wrote a quick hack this afternoon to do "settings import" from a users 
local.conf and whilst it is not a great solution it did spark some 
real-time conversation between Richard and I.

In an attempt at summary, it should be possible to have Hob:
* call bb.parse.handle() to load the user's settings from local.conf
* add appropriate values to the data store based on the parsed 
local.conf values and any appropriate hob settings
* parse as normal to fully populate the data store

Cheers,
Joshua

Re: [PATCH 3/7] Hob: Make layers define in bblayers.conf as default

[Wang, Shane]

Is that in Josh's hand or Dongxiao's hand?
There is a bug https://bugzilla.yoctoproject.org/show_bug.cgi?id=2254 reported by QA, which is related to this issue.
I assigned to Josh temporarily. Please assign to the right owner if I am wrong.

[PATCH 4/7] Revert "lib/bb/ui/crumbs/hig: fix layers_changed test"

[Dongxiao Xu]

We do not sort the layer list, therefore when response_cb, the ordering
is also not needed.

This reverts commit 71c1de347eef07a2059fc4544dc3cae090181f44.

This only makes sense if 3/7 is merged, correct?

Yes, I should have made the comment more clear.

[PATCH 5/7] Hob: Remove some calling of initiate_new_build()

[Dongxiao Xu]

initiate_new_build() function is in async mode and could not be called
before another async function.

Also we could not initialize the build if user simply change a setting,
therefore remove this function.

[PATCH 6/7] Hob: Remove duplication for certain bitbake variables

[Dongxiao Xu]

Sometimes, certain variables have duplicated values inside, for example,
IMAGE_FSTYPES = "tar.bz2 ext3 tar.bz2 ext3"

We need to remove the redundancy for those values.
