[gentoo-dev] glibc ebuilds

[Collins Richey]

You need a new option in portage.  A glibc ebuild (in this case
triggered  by emerge system)  will stop after several hours of
compiles complaining that "this cannot be done when X is active."  You
should detect this up front to avaoid wasting a lot of compile time.

Hi!

Here is a simple patch to glibc-2.2.4-r2.ebuild to check for a running
Xserver and if there is to exit and echo telling the user to quit X and
merge from the console.

Not going to work.  As i am sitting here, if I do a 'su -' to su to
root, $DISPLAY is not defined anymore after su, and it _is_ after all
only root (for the moment anyhow) that can merge packages.

Hi!

My bad. Sorry.  That's what I get for staying up to late.

Hi!

Ok, here is another attempt.  This one checks for a LCK..tty* file in
/var/lock.

Again sorry for the previous brain fart :)

Whatever works.  I'm not repeating this for a third time.  Take your
time and come up with a permanent solution.

Is there any fundamentally good reason why you don't check for the
presence of /tmp/.X?-lock, which XFree itself checks for to determine if
an existing X is running ?


Kind regards,

Yes... my blatant ignorance of X! :)  You are right /tmp/.X?-lock is
the way to check for X running.  As you can tell, I have no qualms about
baring my ass in public.  That said, sheild your eyes.

I recently, updated several gnome-apps to the current versions (I'm
composing this in evo 0.99, thanks hallski!).  While updating, I ran
into a couple situations where I hosed my gnome-session out from under
myself.  Normally, you can safely emerge a gnome-app while running a
gnome-session.  However, if the app emerge triggers an update of one of
the underlying libs through a dependency you will promptly shoot
yourself in the foot.  This happened to me when imlib and gdk-pixbuf
were updated while emerging the new evolution and gnumeric.  It would be
nice if *critical* gnome-libs ebuilds would check to make sure you are
not running a gnome-session before merging, and ask you to drop down
into console mode to do the merge.  

I assume that a kde or other desktop environments would have similar
situations.

ps.  I tried duplicating the glibc emerge failure that was reported, but
didn't see.  However, the error was reported after a emerge system, but
I checked for it with ebuild glibc unpack compile install.  Although I
am sure I would have hosed my self if qmerged, the build and install did
not fail.

Normally it should not be a problem to install a new version of
a library even when programs are currently loaded that are using the
older version.  The problem here is actually that Portage is overwriting
the library without unlinking it first.  Since the library is mmap'd, it
results in offsets being all wrong, so the application (gnome-session in
this case) segfaults.
