[gentoo-dev] Re : Cannot see my eclass modifications

[Farid BENAMROUCHE]

Hi all,
 
 I'm currently developping a patch for user.eclass, but I'm
 banging my head against a wall...
 
 So for testing first, I've setup an overlay, and I now that
 it is taken in account by portage (If I rename portage's
 user.eclass, emerge is still working. If I remove my
 overlay, emerge complains about missing user eclass. So my
 overlay is actually working)
 I've modified enewgroup and egetent for example and put some
 einfo and also modified some other stuffs to be sure that
 I'm entering the function....
 
 Then emerge sys-power/nut, I can see the pkg-setup traces,
 just after the call to enewgroup... but still cannot see my
 eclass modifications!
 I tried to modify directly the
 /usr/portage/eclass/user.eclass file, but still the same
 issue...
 I'm totally puzzled about this point! I'm most likely
 missing a stupid point somewhere...
 
 Anyone knows what could be the problem? Please let me know
 what traces/info you need and I will post them.
 
 Thank you!

Hi,

I'm still searching for the reason why I'm not seeing my eclass modifications... no luck so far.

What can I do to debug portage's behavior?

Thank you

You can't override the eclass used by ebuilds in another repo by default.  You have to  edit /etc/portage/repos.conf/gentoo.conf and adjust a setting.  Man portage or googling about repos.conf should provide more info.

Portage will only use eclasses from your overlay for ebuilds in your
overlay, at least by default. You can force it to use your overlay by
setting eclass-overrides in repos.conf.

I have no idea why you would experience this problem if you are
modifying /usr/portage/eclass directly.

Re: [gentoo-dev] Re : Cannot see my eclass modifications

[Farid BENAMROUCHE]

hum... yes I've setup all the relevant settings in my /etc/portage...
I've also read the man, and still not understanding why.

But At least you are confirming me that directly modifying the user.eclass in /usr/portage/eclass should work!

The exact command line I've used was ROOT=/sysroot emerge -av sys-power/nut, where sysroot is a working x86 rootfs (ie, I can chroot in it) with no portage inside...

PORTAGE_ECLASS_WARNING_ENABLE="1" in the make.conf seems to not work too...

 I have no idea why you would
 experience this problem if you are
 modifying
 /usr/portage/eclass directly.

..ok so if you've got a full chroot, you might want to use 'emerge
--config-root=/path/to/chroot [stuff]' and make sure that the
/etc/portage/repos.conf changes you made are in the chroot too.

Barring that, though, the issue may very well be the type of changes
you're trying to make to user.eclass just not working (or being
called) as expected.

A bunch of us hang out on irc.freenode.org in #gentoo-dev-help , and
stuff like this may be easier to help with in a more interactive
environment like that.

Re: [gentoo-dev] Re : Cannot see my eclass modifications

[Farid BENAMROUCHE]

ok, thank you.I will try the chroot stuff as soon as I have some time.

As for what I'm trying to do: making portage able to add user/groups when using --root option.
This is a known limitation since a long time. I'm currently also discussing this point with the "shadow" upstream team (I have some patches for useradd and groupadd)

So for now I'm trying to make portage to just echo some traces when calling enewgroup for example, when I emerge sys-power/nut as a test package (that package is creating a nut user and group)
I tried to put some einfo at the begining of the  enewgroup function, but I do not see them. I also tryed echo "test" > /tmp/test.txt, and I do no see the file too...

And I see the traces from the nut ebuild (package_setup if I remember properly). And if I remove the nut group from my /etc/group, I do see the enewgroup original traces, but not mine.
It's as if portage is using a different enewgroup function, or a cached one...

I tried the irc last time, but nobody was there (most likely because of the time. I will try tomorrow late afternoon)

Re: [gentoo-dev] Re : Cannot see my eclass modifications

[Farid BENAMROUCHE]

I've made some progress!

In my command line, I was still using the -k argument: ROOT=/sysroot emerge -avk sys-power/nut
It seems like the eclass is inside the binary package and thus ignoring the system eclass. (which make sense to me)
Now I can test my modifications and propose something ;)

thank you
