Description Kamil Páral 2011-09-19 05:08:29 EDT
Description of problem:
rpm db got corrupted when I hit Ctrl+C while doing query. That should not happen.

# rpm -qa xorg*
xorg-x11-server-common-1.10.4-1.fc15.x86_64
xorg-x11-drv-intel-2.15.0-5.fc15.x86_64
xorg-x11-drv-sisusb-0.9.4-5.fc15.x86_64
xorg-x11-drv-dummy-0.3.4-5.fc15.x86_64
xorg-x11-drivers-7.4-2.fc15.x86_64
^C
# rpm -qa xorg*
error: rpmdb: Thread/process 15537/140084772542400 failed: Thread died in Berkeley DB library
error: db4 error(-30974) from dbenv->failchk: DB_RUNRECOVERY: Fatal error, run database recovery
error: cannot open Packages index using db4 -  (-30974)
error: cannot open Packages database in /var/lib/rpm
error: rpmdb: Thread/process 15537/140084772542400 failed: Thread died in Berkeley DB library
error: db4 error(-30974) from dbenv->failchk: DB_RUNRECOVERY: Fatal error, run database recovery
error: cannot open Packages database in /var/lib/rpm

I managed to rebuild the database, that is not a problem. The problem is that it happened in the first place.

Version-Release number of selected component (if applicable):
rpm-4.9.1.1-1.fc15.x86_64

How reproducible:
I saw it for the first time. But I was then trying it again (just run rpm -qa and hit Ctrl+C, and again and again) and in about 10 attempts I managed to break the database again. And in another 10-15 attempts broke it for the third time. So definitely reproducible in one has some patience and luck.

I can upload my whole /var/lib/rpm directory if you want, I backed it up in the broken state.
Comment 1 Panu Matilainen 2011-09-19 05:54:17 EDT
Ok, easily reproduced - this is (mostly) specific to the unlucky rpm 4.9.1* versions: a fix for another db-related issue exposes an old flaw in the signal handling into direct sunlight, requiring another fix that is in HEAD but got left out of 4.9.1*.

Will fix, thanks for reporting this.
Comment 2 Panu Matilainen 2011-09-19 05:58:31 EDT
Oh and btw, despite the scary looking message, it's a relatively harmless error in this context (read-only query). It not database corruption and doesn't need full db rebuild, 'rm -f /var/lib/rpm/__db*' is sufficient.
