Watch out for the libpng 1.4 update

[Etal]

Just wanted to let everyone know that a new major version of libpng appeared in portage today, and if you update mindlessly, you will have massive breakage since libpng is used by practically all graphical packages.

So, if you choose to update to it, you will need to either:

- Rebuild a whole lot of major packages (51 in my case) with revdep-rebuild. (Portage 2.2 won't save you due to the block)

- Or, you would need to have both versions installed. Here's what I did:

Code: Select all

update to version 1.4.2; 1.2.43 gets removed due to a block
# emerge -u libpng

install the 1.2 version (1.2.43-r1) in a slot
# emerge libpng:1.2

a lot of packages are linked against libpng12.so.0, but a symlink is not installed with 1.2.43-r1
# cd /usr/lib
# ln -s libpng12.so.0.43.0 libpng12.so.0 

Hope it helps!

Most of the necessary packages can't be rebuild. Some packages like wxGTK etc. don't find necessary packages. pkgconfig gives a lot of errors that it can not find some libs.

Big warning! You can not even start most of the gnome programs like gnome-terminal etc. All files claim libpng12.so.0
Using AMD64 unstable revdep-rebuilt wants to rebuild 177 files but fails instantly.
I masked libpng-1.4.2 locally and downgrade to libpng12 ...

My list (revdep-bebuild) is 56 packages, and it's going fine (on 25 of 56 now).

~amd64, portage <2.2. Only wm installed is e17 but I do use many gtk apps. ATM, terminal is refusing to launch a new instance, so I'll need to wait a bit before I know if anything is actually broken or just needed to be built against the new pnglib.

For now you can just put

Code: Select all

=media-libs/libpng-1.4.2

into /etc/portage/package.mask since no package requires it so far.

Putting exact versions into the world set is a silly idea. When something does come along in 6 months that requires 1.4.3 or higher, you'll get a fun block to deal with. The most specific level you should use in the world set is slots.

I, for one, am glad that portage does not have a mind of its own

[Naib]

yup big b0rkage

revdep-rebuild would list a load of applications needing a rebuild BUT the rebuild would fail early on (pygtk in this instance, it kept trying to -lpng12 EVEN tho 14 was installed
lafilefixer didn't fix it

I had to manually emerge libglade to get alot of things to rebuild (against libpng14)

Next set of blockages associated with imagemagick (need to find out which one of its deps is being a PAIN!).
Mangler doesn't work either due to it still gets linked against libpng12 during emerge oO which makes no sense

Key package deps and their *.la files have libpng12 coded in them and its a job to find out which ones are causing hte problem...


this is a nasty lib bump

You mean it could do its job even poorly? Anyway it doesn't have a mind of its own like every program it just reflects the minds of its programmers, if technology to prevent this has been already implemented, albeit with some touchable problems, it might time time to give it to the masses

[Muso]

All sorted here. revdep-rebuild finished and a running it again showed consistency.

[Martux]

I for one have only one problem left with net-misc/nxclient-3.4.0.7 which absolutely insists on libpng-1.2.
The other blockers, x11-misc/notification-daemon-0.4.0-r1 and dev-python/pygtk-2.16.0-r1 just played nicely after I did a lafilefixer --justfixit.
Any ideas on nxclient?

[niick]

Whether it was me or portage that was mindless is kind of irrelevant - things are kind of fucked.

I had ~50 packages that needed rebuilding after revdep-rebuild and 25 of those still won't. These are;

pygtk, libgnomeprintui, gnome-media, libgnomecanvas-python, libgnomeui, libbonobo-python,
glade, dia, libgnome-python, teg, eel, celestia, anjuta, goffice-0.4.3, goffice-0.6.6, notification-daemon,
grip, evolution-data-server, evolution, gnome-mount, nautilus-actions, abiword, gnome-panel, gdm and
gnome-applets-python.

This is gentoo and I'm running unstable but this is the biggest breakage I've had in ages, something in eselect news
might have been nice... but it's a Sunday so what else should I do but worship at the altar portage, 25 "hail portages"
seems a bit of steep price for absolution though.

a lot of packages are linked against libpng12.so.0, but a symlink is not installed with 1.2.43-r1
# cd /usr/lib
# ln -s libpng12.so.0.43.0 libpng12.so.0

I'm going to try this now, hopefully it will clear some of these remaining issues.

emerge libglade
then revdep-rebuild

there is a bug or something I can't figure it out but pygtk got blocked for me and I had to manually emerge that to fix it
you might need to emerge libtools manually as well since you will prob run into issues with that later

[niick]

Thanks for the advice Naib, I did what you suggested, ran

Code: Select all

lafilefixer --justfixit

and installed libpng-1.2 slotted as first poster suggested and I'm all sorted now. Well, all the apps I've tried are working again.

[gregool]

it didn't go as i expected

i ran emerge libpng:1.2 as suggested, the symlinks are ok but revdep-rebuild never returned any broken package.

so my problem is that a bunch of packages are still asking for libpng12 ! i tried to emerge libglade as Naib suggested but it quiclky failed asking for libpng12 as well.

lafilefixer didn't do the trick

any ideas?

either slot libpng12 or fix rebuild. you cant do both

if you go for rebuild

#1 make sure you dont have libpng12 install
#2 revdep-rebuild
it will eventually fail
#3 emerge libglade libtools
revdep-rebuild

[gregool]

thx naib

well let's try to rebuild

[gregool]

didn't work

after i removed libpng12 revdep-rebuild found 99 broken packages, and the rebuild crashed on the very 1st package which was cairo so i tried so to rebuild libglade with no luck

[Naib]

iirc I had to emerge cairo by itself.

what is the error when you try to emerge cairo by itself?

[ichbinsisyphos]

I just wanted to make a similar post. 71 packages had to be rebuilt on my system, which made my PC basically unusable for 5 hours. revdep-rebuild fixed everything without problems, though.

[d2_racing]

Thanks for this thread, I'm gonna try tomorrow morning

[sumerman]

it didn't go as i expected

i ran emerge libpng:1.2 as suggested, the symlinks are ok but revdep-rebuild never returned any broken package.


if you go for rebuild

#1 make sure you dont have libpng12 install
#2 revdep-rebuild
it will eventually fail
#3 emerge libglade libtools
revdep-rebuild

This procedure seemed to work for me after struggling much of the day with this problem. Although I successfully emerged packages that I couldn't before I used this procedure (pygtk, libgnomeprintui, and libxfcegui4), it failed on xfce-base/xfce4-panel. I'll keep trying and let you know if I get further along.

[davidm]

Thanks for the heads up. I think I'll wait a week or two before upgrading. I remember all the problems this caused in the past on Arch. Particularly Cairo but also for a lot of custom built apps.

It seems if you don't want to go the slot route, then you have to rebuild everything that was built with libpng:1.2. This will vary depending on what you have installed. My approach was to use the above procedure until a package wouldn't build under revdep-rebuild. Then use

Code: Select all

equery depgraph PACKAGE

and see what the dependencies are, and, in my case, guess which ones depend on libpng. Then rebuild those packages, and do the same procedure if some of those packages don't build successfully.

For example, I executed

Code: Select all

equery depgraph xfce4-panel

and saw dependencies on cairo (which I had already rebuilt after install libpng:1.4), libxfce4util, libxfcegui4, and exo. I then emerged these (using --with-bdeps=y) and they emerged except for exo. Then I did the same procedure for exo and guessed at libnotify and dev-perl/URI (rightly or wrongly), then after emerging them, I successfully emerged exo, and then I successfully emerged xfce4-panel. And on and on.

After doing this recursion about three or four times, I successfully emerged all packages found by revdep-rebuild.

[gregool]

ok i emerged cairo by it self and it worked, but it seems every package has a different work around.

the 2nd on the list is libgnomecanvas-python-2.28.0, and it fails due to gtk+

Code: Select all

 *** Could not run GTK+ test program, checking why...

but when i tried to emerge gtk+ by itself it fails asking for libpng12

so i installed libpng12 again in a slot, so that i can use my desktop.
