Description George Bills 2004-07-27 00:27:13 UTC

The file "/var/cache/edb/world" was left without the full number of entries (my installed programs.)
I did an "emerge -uD apache nano shadow perl ssmtp gvim samba wine flac mozilla (etc)" and ran out of disk space during the updates.  (I didn't emerge world as I didn't have all the distfiles required for a world update.)  Now I've cleared up some space I get absolutely no files needed for upgrading on "emerge -uD -pv world"  I know thats not right because last time I did "emerge -uD -pv world" I had at least 100 packages needing updating and I haven't updated those packages yet.  The file "/var/cache/edb/world" reads:
"sys-apps/shadow
net-www/apache
dev-lang/perl
dev-lang/gnat
mail-mta/ssmtp
app-editors/gvim
app-emulation/wine
media-libs/flac
net-www/mozilla
media-video/nvidia-glx
dev-db/mysql
net-fs/samba
app-editors/nano"
and these are the files that I upgraded.  (I freed up some hard drive space, then pressed the up arrow a few times to recall the "emerge -uD list_of_packages" command I had done before and retried the command (It ran successfully through this time, as I had sufficient hard drive space.))  The world file should contain all packages I have installed (far more than this.)

Reproducible: Sometimes
Steps to Reproduce:
1. Fill up your hard drive (ie leave at most a few meg)
2. Do an emerge -uD large_list_of_packages
3. 
Actual Results:  
program tried to write world file to hard drive, but did not have the space to do so.
program deleted the world file, then on a subsequent update populated it with the programs that were 
updated.

Expected Results:  
program should not try and write the world file to hard drive unless it has the space required to do so.
world file should have been left as it was.

/usr/lib/portage/bin/regenworld is a nice tool.
This bug is pretty old now. The cause is long resolved.
