Bug 41520 – 'emerge -pvU' is very slow when package.keywords exists

• Status: RESOLVED FIXED
• Product: Portage Development

[Description Alkis Evlogimenos 2004-02-13 19:11:43 UTC]

The existence of package.keywords (with portage 2.0.50) makes computing dependencies extremely slow. When the file doesn't exist 'emerge -pvU' runs reasonably fast, in the order of tens of seconds. On the other hand when it exists 'emerge -pvU' takes in the order of couple of minutes.

[Comment 1 Alkis Evlogimenos 2004-02-13 20:09:44 UTC]

Just some numbers to better illustrate the problem:

with package.keywords:    5m26s
without package. keywords:   10s

It should be fixed in 2.0.50-r3.
Can you try it?

[Comment 8 AlterEgo 2004-04-05 10:23:39 UTC]

Masatomo Nakano ,
I did try the new 2.0.50-r3 as was suggested in the topic
http://forums.gentoo.org/viewtopic.php?t=157340.

It turned out to make no difference.

[Comment 9 Masatomo Nakano (RETIRED) 2004-04-05 10:33:39 UTC]

I just tested in 16 lines package.keywords file, but it worked properly.
can you attach your package.keywords file here?

[Comment 10 AlterEgo 2004-04-05 10:39:05 UTC]

My package.keywords:

alsa-lib~x86
alsa-utils~x86
gimp~x86
bootsplash~x86
redhat-artwork~x86
digikam~x86
digikam-plugins~x86
baselayout~x86
sysfsutils~x86
nvidia-kernel~x86
nvidia-glx~x86
openoffice-bin~x86
openoffice-ximian-bin~x86
udev~x86
hotplug-base~x86
hotplug~x86

Even if there is only 1 line in that file, everything slows down completely.

[Comment 11 AlterEgo 2004-04-05 10:40:56 UTC]

Sorry; correct layout this time:
/etc/portage/package.keywords:
alsa-lib ~x86
alsa-utils ~x86
gimp ~x86
bootsplash ~x86
redhat-artwork ~x86
digikam ~x86
digikam-plugins ~x86
baselayout ~x86
sysfsutils ~x86
nvidia-kernel ~x86
nvidia-glx ~x86
openoffice-bin ~x86
openoffice-ximian-bin ~x86
udev ~x86
hotplug-base ~x86
hotplug~ x86

[Comment 12 AlterEgo 2004-04-10 08:27:05 UTC]

I rm-ed the file and built a new /etc/portage/package.keywords. 
Identical contents. 
Problem fixed.
