While populating the package sack, yum did not account for the possibility repos had been added where none existed before. Therefore, if the repos were not specified in the original configuration, and repos were subsequently added, yum would not add to the package sack the first time that it tried to use the new repos. This situation could lead to problems during installation or the creation of live CDs. Yum now re-initializes the package sack when a repo is added if no repo was previously specified.

Description Petr Sklenar 2009-06-29 07:22:24 EDT
+++ This bug was initially created as a clone of Bug #508139 +++ This is a problem because we need live cds to run the f12 test days. [mclasen@planemask spin-kickstarts]$ sudo livecd-creator --config fedora-livecd-desktop.ks mke2fs 1.41.6 (30-May-2009) Filesystem label=fedora-livec-x86 OS type: Linux Block size=4096 (log=2) Fragment size=4096 (log=2) 196608 inodes, 786432 blocks 7864 blocks (1.00%) reserved for the super user First data block=0 Maximum filesystem blocks=805306368 24 block groups 32768 blocks per group, 32768 fragments per group 8192 inodes per group Superblock backups stored on blocks: 32768, 98304, 163840, 229376, 294912 Writing inode tables: done Creating journal (16384 blocks): done Writing superblocks and filesystem accounting information: done This filesystem will be automatically checked every 26 mounts or 180 days, whichever comes first.

Is this an i386 or x86_64 host? Does 'yum install kernel' do the right thing? --- Additional comment from firstname.lastname@example.org on 2009-06-25 16:35:09 EDT --- x86_64 host. > Does 'yum install kernel' do the right thing? Seems to: [mclasen@planemask gnome-panel-2.26.2]$ sudo yum install kernel Loaded plugins: dellsysidplugin2, presto, refresh-packagekit Setting up Install Process Package kernel-2.6.31-0.28.rc1.fc12.x86_64 already installed and latest version Nothing to do --- Additional comment from email@example.com on 2009-06-26 12:12:16 EDT --- This is broken by commit 5216a27d35d60e46f028b1fbba58acae5b9e79d2 in yum -- if you initially set up without any repos (==> len(ayum.pkgSack)=0) and then add repos, yum no longer adds to the pkgSack on the first access with the new repos. It's a side effect, but it's a side effect that both livecd-creator and anaconda depend on working (and thus, probably that other tools do as well) --- Additional comment from firstname.lastname@example.org on 2009-06-26 12:53:42 EDT --- Crap ... this just went into the RHEL-5.4 candidate too. Ok, so here's what I think we can do (to fix both bugs): commit 0e9c56de28596bad95c13fee15187df3249f4be1 Author: James Antill <email@example.com> Date: Fri Jun 26 12:51:12 2009 -0400 Re-setup the pkgSack whenever the sacks change diff --git a/yum/__init__.py b/yum/__init__.py index be98aae..ef793f6 100644 --- a/yum/__init__.py +++ b/yum/__init__.py @@ -480,8 +480,11 @@ class YumBase(depsolve.Depsolve): """populates the package sacks for information from our repositories, takes optional archlist for archs to include""" - if self._pkgSack is not None and thisrepo is None: + pkgSack_count = len(self.repos.pkgSack.sacks) + if (self._pkgSack is not None and + pkgSack_count == self._old_pkgSack_count and thisrepo is None): return self._pkgSack + self._old_pkgSack_count = pkgSack_count if thisrepo is None: repos = 'enabled' ...can you confirm, if so I'll puch it everywhere. --- Additional comment from firstname.lastname@example.org on 2009-06-26 12:58:51 EDT --- Ok, that's insane ... because the sacks come from populateSacks, which is inside that function ... I think the only way we can do this is test to see if listEnabled() has changed. Probably the fastest way to do that is put some timestamp in the repos object, and then check if timestamp == old_timestamp. --- Additional comment from email@example.com on 2009-06-26 13:24:53 EDT --- How about we fix the problem separately in package-cleanup and not modify yum? --- Additional comment from firstname.lastname@example.org on 2009-06-26 14:42:00 EDT --- It's not just package-cleanup that hits it, it also hit at least versionlock ... and generally anything 485578 that uses .pkgSack when they are empty due to excludes (I think). I'm also not sure how we can fix it at a higher level. I've pushed a patch which is almost all comment and I think fixes it with no bad side effects ... Jeremy can you have a look? http://yum.baseurl.org/gitweb?p=yum.git;a=commitdiff;h=06e7d4492846f30d03e400d795bd353bdac6ab77 --- Additional comment from email@example.com on 2009-06-26 14:43:10 EDT --- Yep, I'm on top form ... I pasted the above BZ number into the wrong place and pushed the commit without adding it to the summary. I shall now go drink some cherry coke and wait for my holiday to start. --- Additional comment from firstname.lastname@example.org on 2009-06-28 19:45:34 EDT --- The patch in comment 8 at least allows livecd-creator to get to the point where it falls over broken dependencies in rawhide. I guess thats progress...
