Bug 50489 – Unable to emerge various packages (opengl-update, kde-env, kde, etc.) because of zero-sized digests

• Product: Gentoo Linux
• Status: VERIFIED NEEDINFO

[Description wiktorw 2004-05-08 14:55:53 UTC]

I downloaded Gentoo 2004.1 and I sucessfully installed it. I went through "Stage1" and "Stage2" (and I am not bragging :-)
However, when I try to emerge additional packages, in some cases it is impossible to do so. In such a case emerge says something like:
"[empty/missing/bad digest]" at the end of description for a package.
Example:
[ebuild  N    ] kde-base/kde-env-3-r2   [empty/missing/bad digest]

I have just found these strange digest files in portage tree. They are zero-sized. And there are plenty of them: 176 in "portage-20040430" and 165 in "portage-20040507". So the problem is persistent!

This way I am unable to emerge various packages, especially xfree and kde.
Since ebuild depends on these digest files to know what to build and in what order, I suppose other users can reproduce the same bug. So in my opinion this is somewhat important.

Because of the above I am very unhappy to run text-only version of Gentoo :-(
But I hope this is something that can be relatively easy to fix. :-)


Reproducible: Always
Steps to Reproduce:
There are at least two ways of reproducing the problem.

1. On a clean system, after "stage2" compilation, do:
   emerge sync
   emerge -pv kde     (( <-- warnings! ))
1A.
   ls -l /usr/portage/x11-base/opengl-update/files
   (( you can see that all digest-* files are zero-sized ))
1B.
   cat /usr/portage/x11-base/opengl-update/Manifest | grep digest | less
   (( you can see again that indeed digest-* files are zero-sized ))

2. Download snapshot "portage-20040507.tar.bz2" and execute:
   tar -tvjf portage-20040507.tar.bz2 | grep "^-.* 0 .*digest" > bad-digests
   You should see in reulting file 165 zero-sized "digest-*" files
   (for "portage-20040430.tar.bz2" there are 176 such files)

Actual Results:  
For 1.
======

emerge -pv kde

These are the packages that I would merge, in order:

Expected Results:  
For 1.
======
Packages opengl-update, kde-env, kde downloaded, compiled and installed 
successfuly.

For 2.
======
No zero-length digest files in portage tree.


sorry, I'm posting from different machine, so 'emerge info' is impossible 
right now...

i actually noticed files like that during an install I did this week.  I didn't have any problems emerging though.. yours fails?

[Comment 2 Mr. Bones. (RETIRED) 2004-05-09 19:56:22 UTC]

reopen with the output of emerge --info please.

[Comment 3 wiktorw 2004-05-09 22:53:10 UTC]

Created attachment 31082 [details]
success!

Two days later - and the result is a success...

As you requested I included the output of "emerge info".
However, I don't think this will be needed.

As I read more on emerge and ebuild I noticed how to specify an exact
version of package needed. This is what I did:

-----------------------------------------------------------------------
# emerge sync
# emerge -pv opengl-update

These are the packages that I would merge, in order:

Calculating dependencies ...done!
[ebuild  N    ] x11-base/opengl-update-1.5   [empty/missing/bad digest]

Total size of downloads: 0 kB
-----------------------------------------------------------------------

At this point something hit my mind:

-----------------------------------------------------------------------
# emerge x11-base/opengl-update-1.5
Calculating dependencies
!!! Problem in x11-base/opengl-update-1.5 dependencies.
!!! "Specific key requires an operator (x11-base/opengl-update-1.5) (try adding an '=')"

# emerge =x11-base/opengl-update-1.5

>>> No outdated packages were found on your system.


 * GNU info directory index is up-to-date.
-----------------------------------------------------------------------

And the story is over. Simple "emerge =x11-base/opengl-update-1.5"
solved everything.

Moral:
  don't post a bug until you are COMPLETELY sure it is a bug.

Thanks for your time, guys. For me this bug is closed.
