Bug 307409 – sys-apps/portage-2.2* deploop deptree dump hides some useflags

• Product: Portage Development
• Status: RESOLVED FIXED

[Description Nathan Phillip Brink (binki) (RETIRED) 2010-03-02 02:08:41 UTC]

I'll attach a log that shows the full output out of which I am grabbing excerpts for below:

I passed -vp1 to emerge:

[nomerge      ] net-print/cups-1.3.11-r1 [1.3.10-r2] USE="lib32%* -X* -dbus* -java* -php* -xinetd*"
[ebuild  N    ]  app-text/poppler-0.12.3-r3  USE="abiword cairo cjk jpeg jpeg2k lcms lib32 png utils xpdf-headers -debug -doc -exceptions -qt4"
[ebuild   R   ]   x11-libs/gtk+-2.16.6  USE="lib32%* -doc*"
[ebuild     U ]    net-print/cups-1.3.11-r1 [1.3.10-r2] USE="lib32%* -X* -dbus* -java* -php* -xinetd*"

See that the package which is being newly merged has all of its useflags shown. In the case of deploop solving, however, one would be benefited by seeing all of the useflags that are enabled even on packages that are being reinstalled. This is because deploop solving involves temporarily disabling useflags, etc.

In the above example, gtk+ has a cups useflag which is enabled and could be temporarily disabled by the user to break the deploop. Yet to find that information, I consulted eix ;-)

oh, sorry, I forgot to mention that I'm using tommy[d]'s portage-multilib branch, version 2.2_rc63-r1.

bug 175808 doesn't seem to address the issue this bug is filed against. I thought I made it clear that I'm requesting that portage be more verbose to better enable users to break out of deploops. I'd imagine that a fix to this bug would be trivial compared to the other bug.

Or maybe I'm missing some flag/argument I may pass to portage that makes it more verbose somehow?

This is fixed in 2.1.8.2 and 2.2_rc66.
