I think in some bug report I already asked that 'revdep-rebuild -i' should invoke 'emerge --keep-going'. Here I see a broken behavior of python-updater: # python-updater * Starting Python Updater... * Main active version of Python: 2.7 * Active version of Python 2: 2.7 * Active version of Python 3: 3.2 * Globally supported Python ABIs in installed repositories: * gentoo: 2.4 2.5 2.6 2.7 3.1 3.2 3.3 2.5-jython 2.7-jython 2.7-pypy-1.7 2.7-pypy-1.8 2.7-pypy-1.9 2.7-pypy-2.0 * science: 2.4 2.5 2.6 2.7 3.1 3.2 3.3 2.5-jython 2.7-jython 2.7-pypy-1.7 2.7-pypy-1.8 2.7-pypy-1.9 2.7-pypy-2.0 * x-layman: 2.4 2.5 2.6 2.7 3.1 3.2 3.3 2.5-jython 2.7-jython 2.7-pypy-1.7 2.7-pypy-1.8 2.7-pypy-1.9 2.7-pypy-2.0 * x-portage: 2.4 2.5 2.6 2.7 3.1 3.2 3.3 2.5-jython 2.7-jython 2.7-pypy-1.7 2.7-pypy-1.8 2.7-pypy-1.9 2.7-pypy-2.0 * Adding to list: app-portage/gentoolkit:0 * Adding to list: dev-python/argparse:0 * Adding to list: dev-python/beautifulsoup:python-3 * Adding to list: dev-python/bsddb3:0 * Adding to list: dev-python/dbus-python:0 * Adding to list: dev-python/elementtree:0 * Adding to list: dev-python/imaging:0 * Adding to list: dev-python/lxml:0 * Adding to list: dev-python/matplotlib:0 * Adding to list: dev-python/mysql-python:0 * Adding to list: dev-python/pycairo:0 * Adding to list: dev-python/pycxx:0 * Adding to list: dev-python/pygobject:2 * Adding to list: dev-python/pygtk:2 * Adding to list: dev-python/pyrex:0 * Adding to list: dev-python/pysqlite:2 * Adding to list: dev-python/pytz:0 * Adding to list: dev-python/pyxml:0 * emerge -Dv1 --keep-going app-portage/gentoolkit:0 dev-python/argparse:0 dev-python/beautifulsoup:python-3 dev-python/bsddb3:0 dev-python/dbus-python:0 dev-python/elementtree:0 dev-python/imaging:0 dev-python/lxml:0 dev-python/matplotlib:0 dev-python/mysql-python:0 dev-python/pycairo:0 dev-python/pycxx:0 dev-python/pygobject:2 dev-python/pygtk:2 dev-python/pyrex:0 dev-python/pysqlite:2 dev-python/pytz:0 dev-python/pyxml:0 * IMPORTANT: 18 news items need reading for repository 'gentoo'. * Use eselect news to read news items.

This is really not specific to python-updater; it would happen any time you start a merge with an unsatisfied REQUIRED_USE constraint. I think the current behavior is reasonable, but I can see the other side of it as well.
What you really want is a combination of bug 403207 and bug 258371, so that emerge will automatically satisfy REQUIRED_USE. It is beyond the scope of --keep-going. *** This bug has been marked as a duplicate of bug 258371 ***
I don't think this is enough for me. If for whatever reason a child emerge dies then the process of reinstalls to be done by revdep-rebuild will just stop the iteration. I really want revdep-rebuild to continue, like I get with the simple shell loop which effectively ignores that some of the children failed. This is even more helpful because emerge often fails to resolve ordering of packages so it is anyway just a random ordering. And therefore, this stupid shell loop is just the right thing to do to get at least some broken fixed. In the attempt to run 'revdep-rebuild -i' one will get less pakages and maybe will get all fixed. Why do we have to wait for a magic, sophisticated fix? Please make a workaround until a proper fix (bug #403207 and bug #258371) exists. Ideally REOPEN the bug as I don't think this has to be marked as a duplicate. Anyway, thanks for your time.
(In reply to Martin Mokrejš from comment #3) > Please make a workaround until a proper fix (bug #403207 and bug > #258371) exists. I'm not sure what you're suggesting. Do you want emerge to ignore REQUIRED_USE, skip packages with unsatisfied REQUIRED_USE, or are you suggesting a change to python-updater?
[I have reworked my comment hopefully to make it clearer.] I don't think this is enough for me. If for whatever reason a child emerge process forked by python-updater dies then revdep-rebuild does not continue the list of packages to be reinstalled. I really want revdep-rebuild to continue, like I get with the simple shell loop which effectively ignores that some of the children failed. This is even more helpful because emerge (or revdep-rebuild?) often fails to resolve ordering of packages so it is anyway just a random ordering of packages in a row. And therefore, this stupid shell loop is just the right thing to do to get at least some broken packages reinstalled. In a subsequent attempt to run 'revdep-rebuild -i' one will get less pakages and maybe will get through at the second pass. Why do we have to wait for a magic, sophisticated fix? Please make a workaround so that *revdep-rebuild calls emerge child processes in a loop* until a proper fix (bug #403207 and bug #258371) exists. In other words, ignore the exitcode of children. Ideally REOPEN the bug as I don't think this has to be marked as a duplicate. Anyway, thanks for your time.

In brief, while not knowing what I am really talking about, the 2) or 3) sounds like what I probably want (in terms of functionality).
Skipping packages with unsatisfied REQUIRED_USE fits bug 328343. Once that's fixed, python-updater will be able to make use of it. *** This bug has been marked as a duplicate of bug 328343 ***
