Description dE 2009-12-22 07:03:00 UTC
Portage states - 
"[ebuild     U ] app-shells/bash-4.0_p35 [4.0_p28] USE="-mem-scramble%"
[blocks B     ]  <sys-libs/e2fsprogs-libs-1.41.8 ("<sys-libs/e2fsprogs-libs-1.41.8" is blocking sys-apps/util-linux-2.16.1)"

However masking sys-libs/e2fsprogs-libs-1.41.8 does not help.

Also notice that - 

"de@localhost / $ emerge --search e2fsprogs-libs
Searching...    
[ Results for search key : e2fsprogs-libs ]
[ Applications found : 1 ]

*  sys-libs/e2fsprogs-libs

But portage somhow wants to install sys-libs/e2fsprogs-libs-1.41.8.

Notice, according to eix, sys-libs/e2fsprogs-libs-1.41.8 is masked - 

"e@localhost / $ eix e2fsprogs-libs
[U] sys-libs/e2fsprogs-libs
     Available versions:  1.41.3-r1 ~1.41.6 ~1.41.7 [m]~1.41.8 1.41.9 {nls}

     Description:         e2fsprogs libraries (common error and subsystem)

"
But portage still want to install it in prefference to sys-libs/e2fsprogs-libs-1.41.9...notice I've manually maked sys-libs/e2fsprogs-libs-1.41.8

So there are actually 2 bugs here, one, portage preffering sys-libs/e2fsprogs-libs-1.41.8 instead of sys-libs/e2fsprogs-libs-1.41.9 and second that portage wants to install sys-libs/e2fsprogs-libs-1.41.8 depite the fact that It's listed in pacakge.mask.

It should have atleast stated that sys-libs/e2fsprogs-libs-1.41.8 is a depency required by some pakage (if there are any) but it has been masked.

Reproducible: Always

Steps to Reproduce:
emerge --pretend --update --deep --complete-graph --tree world

(Above, I've posted relevant parts only)


Expected Results:  
It should have tried to install sys-libs/e2fsprogs-libs-1.41.9 instead of sys-libs/e2fsprogs-libs-1.41.8

You've misunderstood the message. Masking sys-libs/e2fsprogs-libs-1.41.8 is not the appropriate course of action. You currently have sys-fs/e2fsprogs-1.41.3-r1 installed, which is matched by <sys-libs/e2fsprogs-libs-1.41.8. You need to upgrade to the latest e2fsprogs-libs in order for this blocker to solve, and it looks like that is happening already here:

[ebuild     U ]   sys-libs/e2fsprogs-libs-1.41.9 [1.41.3-r1]

So, it seems like you can really ignore the e2fsprogs-libs blocker. It's probably just a display bug in portage. I suspect that you only need to solve the x11-libs/libXi blocker and the whole upgrade will succeed.

As for solving the x11-libs/libXi blocker, I don't understand why the older x11-libs/libXi-1.2.1 package got pulled into the dependency graph. Can you please post emerge output for the same command with the --debug option enabled?
Comment 3 Zac Medico gentoo-dev 2009-12-22 13:05:14 UTC
Also, please try with latest portage since that might affect the results (you posted with 2.2_rc50 but latest is 2.2_rc60).

"As for solving the x11-libs/libXi blocker, I don't understand why the older
x11-libs/libXi-1.2.1 package got pulled into the dependency graph."

That's cause I'm masked =x11-libs/libXi-1.2.99.

The display bug remains identical with portage-2.2_rc60

I've unmasked x11-libs/libXi and this is the new output (with portage-2.2_rc60) has been attached. 

As of this block -

[blocks B     ] <x11-libs/libXi-1.2.99 ("<x11-libs/libXi-1.2.99" is blocking x11-proto/inputproto-2.0)

I do not understand why does portage wants to install x11-libs/libXi-1.2.99 cause it's already being upgraded to - 

"[ebuild     U ]   x11-libs/libXi-1.3 [1.2.1]
"

As shown in the tree.

Furthermore there are no packages called libXi-1.2.99 -

And I think this was the thing you where referring to.

Output of emerge --pretend --update --deep --complete-graph --tree --debug world has been attached.

Output of emerge --pretend --update --deep --complete-graph --tree --debug world (compressed text file)

The text file has been compressed using lpaq9m algorithm, download the binary/sources from - 

http://cs.fit.edu/~mmahoney/compression/lpaq9m.zip

or

http://artst.narod.ru/b/lpaq9m.zip

Compile the single c source code and run

./<binary file name that got compiled> d <path of debug_out.lpaq9m> <path of uncompressed output file>

Well, using some oddball compression like that is just stupid. :P

This is the same output as attachment 213758 [details] but with bz2 compression, so others can see this without having to use lpaq9m. Seriously, it's just wrong to make people use lpaq9m. :)

No, you still have a fundamental misunderstanding of blocker atoms. Masking =x11-libs/libXi-1.2.99 doesn't really change anything because that package doesn't really exist and the !<x11-libs/libXi-1.2.99 blocker matches *all* versions lower than that.

Anyway, the debug output shows that libXi-1.2.1 got pulled in by xfce-base/xfce4-settings-4.6.3 since it has <x11-libs/libXi-1.3 in RDEPEND. Apparently you need to unmask xfce-base/xfce4-settings-4.6.3-r1 in order to solve that. If you do that then hopefully all blockers will resolve.
Comment 10 dE 2009-12-24 16:08:35 UTC
Well, it's is disputably the best compression in the world; I thought why not introduce it to the developers...very interesting stuff. It appears as if it took lots of time and memory for your system to decompress it...
Good thing I didn't use paq, it has many times the requirement of memory and time.:)

Thanks all problems have resolved now (all of a sudden, without masking or unmasking).
Comment 11 Zac Medico gentoo-dev 2009-12-24 21:30:17 UTC
Yeah that lpaq9m file was many times smaller than the bz2 file. It said decompression consumed 198 meg iirc (many times the file size).

NOTE: For smaller emerge --debug logs, use --backtrack=0.

TODO:

This blocker should appear as solved:

	[blocks B     ]  <sys-libs/e2fsprogs-libs-1.41.8 ("<sys-libs/e2fsprogs-libs-1.41.8" is blocking sys-apps/util-linux-2.16.1)

This blocker message should show the <x11-libs/libXi-1.3 required by
xfce-base/xfce4-settings-4.6.3 RDEPEND:

	('installed', '/', 'x11-libs/libXi-1.2.1', 'nomerge') pulled in by
		x11-libs/libXi required by ('installed', '/', 'x11-libs/gtk+-2.16.6', 'nomerge')
		>=x11-libs/libXi-1.2.1 required by ('ebuild', '/', 'x11-base/xorg-server-1.6.5-r1', 'merge')
		x11-libs/libXi required by ('installed', '/', 'dev-python/pyopengl-3.0.0', 'nomerge')
		(and 10 more)
