 FS#34066  describes the effect this bug has on devtools. But the underlying bug is with pacman so this task is more appropriate.

Set IgnorePkg=foo and run pacman -Sp foo. Instead of seeing the URL for the package foo as stored on the highest priority mirror, you will see an empty string. This is a bug since documentation says --ignore will only take effect on a sysupgrade operation not a print.

Moreover, this behaviour is confusing since it is the opposite of what --noconfirm would do. The options --noconfirm and --print are both supposed to surpress questions. However the question "Foo is in IgnorePkg/IgnoreGrp install anyway?" defaults to "yes" with --noconfirm meaning that pacman will continue the operation and install the package. However, the same question defaults to "no" with --print meaning that pacman stops what it is doing and returns.

The reason for this in the code is fairly clear. The question_cb function returns without a value whenever config->print is TRUE, leaving the value at the mercy of libalpm. It should really return predictable default values similar to how config->noconfirm would.
This task depends upon

How about the following scheme:

--print _asks_ about ignored packages. (Edit: That would break "pacman -Sup > download.list")

If you wish to automatically print all ignored packages, use --noconfirm _with_ --print.

My reason for this is that you may use "pacman -Sup" to get the links to all packages for _the exact operation_ you want to do, so that you can download them on another system.

What you are asking seems to make that impossible (barring grepping out the ignored packages).

pacman -S foo asks the question "would you like to install foo?"
pacman -Su does not ask, it just says "skipping foo."

The patch I'm proposing would only change the API when a question is asked. So the behaviour of -Sp changes but -Sup does not.

Unlike previous versions of the patch, no one commented on this one when I sent it to the mailing list. Sticking it here until people have time.
