[RFC 0/2] useradd improvements

[Eilís 'pidge' Ní Fhlannagáin]

This patch series includes tests for a few deficits in useradd and a patch to
user add that should fix a few issues with recipes who have useradd 
interdependencies. It's still a WIP, but after discussion with RP I wanted
to send this out.

[RFC 2/2] useradd.bbclass: ensure sysroot_setscene for DEPENDS

[Eilís 'pidge' Ní Fhlannagáin]

[YOCTO #13419]

If recipeB creates a user and assigns it to a group created in recipeA,
we need to ensure two things:

That recipeA is in recipeB's DEPENDS (documentation issue) and that the
sysroot setscene, in the case of a TMPDIR wipeout, is in
USERADDSETSCENEDEPS.

RP and I discussed adding a USERADD_DEPENDS variable to deal with this,
but there is some magic around DEPENDS that a new variable wouldn't have
so I'm sending this as is for people to poke at.

This commit should also fix issues seen in the following bugs:

https://bugzilla.yoctoproject.org/show_bug.cgi?id=13279

Can you be more specific about this "magic"?

I'm still worrying that DEPENDS is too broad, there are many more
things in there which we don't want listed as setscene dependencies and
I think this needs to be more precise.

Cheers,

Richard

The interesting thing here is if we do something like:

python __anonymous() {
     setscenedeps = ""
     if "-native" not in d.getVar("PN") and d.getVar("USERADD_DEPENDS") 
is not None:
         for pkg in d.getVar("USERADD_DEPENDS").split():
             setscenedeps += " %s:do_populate_sysroot_setscene " % pkg
         d.setVar("USERADDSETSCENEDEPS", "%s %s" % 
(d.getVar("USERADDSETSCENEDEPS"), setscenedeps))
}

we end up throwing:

ERROR: creategroup2-1.0-r0 do_prepare_recipe_sysroot: The sstate 
manifest for task 'creategroup1:populate_sysroot' (multilib variant '') 
could not be found.
The pkgarchs considered were: qemux86_64, core2-64, x86_64, allarch, 
none_none-nativesdk.
But none of these manifests exists:
 
/home/pidge/poky/build/tmp/sstate-control/manifest-qemux86_64-creategroup1.populate_sysroot
 
/home/pidge/poky/build/tmp/sstate-control/manifest-core2-64-creategroup1.populate_sysroot
 
/home/pidge/poky/build/tmp/sstate-control/manifest-x86_64-creategroup1.populate_sysroot

/home/pidge/poky/build/tmp/sstate-control/manifest-none_none-nativesdk-creategroup1.populate_sysroot

The weird thing (hence this being an RFC), is that the patch I sent 
doesn't throw this. At first, I thought it was something happening with 
a polluted sstate but I don't think so now. I am absolutely unsure as to 
why that would be, BUT my suspicion is that this error is related to 
14961 (which I'm still poking at).

I had a crack at this tonight. Interestingly enough, limiting the code 
"fixes" the issue, eg and allows us to use USERADD_DEPENDS:

if "-native" not in d.getVar("PN") and d.getVar("USERADD_DEPENDS") is 
not None and d.getVar("BB_CURRENTTASK") == "package":

I guess my question is why would it work with DEPENDS but fail with 
USERADD_DEPENDS unless we limited to do_package? (hence the magic I'm 
seeing). I'm still guessing this is something in staging.bbclass that is 
doing something funny.

A bit more on this. The above is incorrect in that DEPENDS certainly is 
special in this context (I had inadvertently switched to 'bitbake -f -c 
package').

Not using the useradd patch works with -f -c (which makes sense)
So initial patch works with either -f -c or -c
Subsequent USERADD_DEPENDS code works with -f -c only.

Which tells me that there is something special about basing the patch on 
DEPENDS which isn't doing what USERADD_DEPENDS is doing, which again 
points to something deep in staging.

Unfortunately this test isn't safe for a shared sstate cache like we
have on the autobuilder since we should never use cleansstate there
without special handling (isolated cache). You would also never need -f
with clean*.

Instead you could do something like a "bitbake creategroup2 -C fetch"
if you always want it to rebuild.
