Description Jens Petersen 2009-09-11 03:45:16 UTC
Description of problem:
When pkgcon runs for installing a missing package command
it seems to hang grabbing the cpu...

Version-Release number of selected component (if applicable):
PackageKit-0.5.2-1.fc12

How reproducible:
every time

Steps to Reproduce:
$ rpm -q rubygems
$ gem 
Command not found. Install package 'rubygems' to provide command 'gem'? [N/y] y
The following packages have to be installed:
1	rubygems-1.3.1-3.fc12.noarch
2	ruby-irb-1.8.6.369-3.fc12.i686
3	ruby-rdoc-1.8.6.369-3.fc12.i686
Proceed with changes? [N/y] y

    client=<value optimized out>) at pk-console.c:2223

Expected results:
Root password dialog to appear and install to get done and complete.

Additional info:
This was working recently... I can try reverting to an older build.

$ pkcon install rubygems

brings up a root auth dialog for rawhide unsigned and seems to work.

Oops sorry that was the wrong backtrace: though the [N/y] download prompt
is also use all cpu. ;-)

Cool, thanks for reporting:

    Read unbuffered input rather than using ungetc. Fixes rh#522679

Comment 3 Jens Petersen 2009-09-29 06:45:12 UTC
Still happens for me with PackageKit-0.5.3-0.1.20090921git.fc12.

Comment 4 Richard Hughes 2009-09-29 07:57:44 UTC
Should be fixed in yesterdays build, can you please test http://koji.fedoraproject.org/koji/buildinfo?buildID=134033 -- thanks.

This doesn't look good even if it is something else...

(Anyway I am opening a Blocker bug to have
PackageKit-command-not-found removed from Live.)
