Summary and Info: Hello, i would like the developers to look into the current behaviour of the CleanMethod option of pacman.conf.

I have CleanMethod = KeepInstalled

The issue at hand is that i have some packages added to IgnorePkg, and pacman -Sc cleans the currently installed version of the packages from the pacman cache, if there is an update available in the repository.

For e.g.

I have vlc 1.1.5-2 installed currently and have added vlc to IgnorePkg. The latest version of vlc is 1.1.6-1.
pacman -Sc cleaned vlc-1.1.5-2-i686.pkg.tar.xz, and so i have no installer package available if i need to re-install vlc.

Steps to Reproduce:

Add a package to IgnorePkg, wait for an update to appear in the repositories. Now try pacman -Sc. This should delete the package from the cache.
This task depends upon

This doesn't make any sense- I can't reproduce it at all. We don't even consider ignored packages as part of the equation here, and when using KeepInstalled, we don't look at the sync databases at all.

I was able to hack pactest to be able to verify this; I will try to clean that up enough to include it. However, this report seems a tad iffy- are you absolutely positive it was pacman that removed it? Do you use a shared cache? We need some more details. The test case is attached I used for this, although it needs the pactest modifications as noted to actually run, but if someone could verify it is testing this case that would be great.

I don't use a shared cache, and i didn't remove the files manually. I run pacman -Sc on a regular basis though. And only the files added to IgnorePkg and the ones from aur, are missing from the cache. I wonder what else could be the cause.

EDIT: Damn, i am an idiot. I just remembered that a few months ago i had changed CleanMethod = KeepCurrent, but reverted back after some time. Now i probably ran pacman -Sc during that period, and that lead to the deletion of the packages from the cache. Sorry for the false alarm, please discard this ticket.

As an FYI, Dan provided a patch allowing both KeepCurrent and KeepInstalled to be specified so that you can have the best of both worlds with the next pacman release:
