Comment 2 Dieter Verfaillie 2013-10-07 12:08:58 UTC
Hmmm, looking a bit closer reveals that $__PORTAGE_HELPER_CWD
is set to ${PWD} or in other words "/var/tmp/portage/dev-python/pygobject-3.8.3/work/pygobject-3.8.3-python2_7/gi".
in "/usr/lib64/portage/bin/ebuild-helpers/xattr/install", which
is supposed to avoid unsafe imports as noted in bug #469338.

So, when Python evaluates "import os", eventually we get an
"import types" [1] which results in
being loaded which is clearly not what we want...

Honestly, I fail to see what's safe about this as just about any package
using the "install" command might come with a file shadowing a highly
used Python module name. Such package doesn't even need to actually install
such a file, it just needs to exist.

Anyway, setting $__PORTAGE_HELPER_CWD to whatever else works around this
specific issue but then later the pygobject build fails with:

Looks like I'm stuck then :(

Maybe reinstall sys-apps/portage.
Comment 4 Dieter Verfaillie 2013-10-08 11:12:50 UTC
Did some more debugging and both
"/usr/lib64/portage/bin/ebuild-helpers/xattr/install" and
"/usr/lib64/portage/bin/" are working just fine.

Looking into "/var/tmp/portage/dev-python/pygobject-3.8.3/work/pygobject-3.8.3-python2_7/gi/Makefile"
we see that "am__py_compile" is called right after "INSTALL_DATA":

install-pygiPYTHON: $(pygi_PYTHON)
        @list='$(pygi_PYTHON)'; dlist=; list2=; test -n "$(pygidir)" || list=; \
        if test -n "$$list"; then \
          echo " $(MKDIR_P) '$(DESTDIR)$(pygidir)'"; \
          $(MKDIR_P) "$(DESTDIR)$(pygidir)" || exit 1; \
        fi; \
        for p in $$list; do \
          if test -f "$$p"; then b=; else b="$(srcdir)/"; fi; \
          if test -f $$b$$p; then \
            $(am__strip_dir) \
            dlist="$$dlist $$f"; \
            list2="$$list2 $$b$$p"; \
          else :; fi; \
        done; \
        for file in $$list2; do echo $$file; done | $(am__base_list) | \
        while read files; do \
          echo " $(INSTALL_DATA) $$files '$(DESTDIR)$(pygidir)'"; \
          $(INSTALL_DATA) $$files "$(DESTDIR)$(pygidir)" || exit $$?; \
        done || exit $$?; \
        if test -n "$$dlist"; then \
          $(am__py_compile) --destdir "$(DESTDIR)" \
                            --basedir "$(pygidir)" $$dlist; \
        else :; fi

am__py_compile = PYTHON=$(PYTHON) $(SHELL) $(py_compile)
PYTHON = /usr/bin/python2.7
SHELL = /bin/sh
py_compile = $(top_srcdir)/py-compile
top_srcdir = ..
and just in case:
abs_top_srcdir = /var/tmp/portage/dev-python/pygobject-3.8.3/work/pygobject-3.8.3-python2_7

This means that after " and" are copied to
the command "PYTHON=/usr/bin/python2.7 SHELL=/bin/sh /var/tmp/portage/dev-python/pygobject-3.8.3/work/pygobject-3.8.3-python2_7/py-compile"
is executed.

That's a shell script created by automake which executes
a "/usr/bin/python2.7 -c 'a whole bunch of code including import os'",
which is what's causing the build to fail due to the current working
directory having a file shadowing python's stdlib types module.

Conclusion: this is neither a pygobject, pygobject-3.8.3.ebuild nor portage
but an automake bug (in py-compile). We can work around it though by getting
rid of py-compile with this simple (but evil) patch:

Comment 5 Pacho Ramos gentoo-dev 2013-10-08 18:54:00 UTC
Please provide "emerge --info", I think latest automake versions fix a bug with py-compile
Comment 6 Dieter Verfaillie 2013-10-09 07:00:02 UTC
(In reply to Pacho Ramos from comment #5)

> with py-compile

Sadly a 3-way diff suggests there's very little differences regarding
py-compile between automake 1.11.6, 1.12.6 and 1.14 and no single
difference related to "python -c" usage without guarding against
shadowed imports...

Comment 7 Pacho Ramos gentoo-dev 2013-10-09 16:54:44 UTC
I was talking about:

But this looks like a different problem, not sure what would be the best way to disable py-compile then :/
Comment 8 Michał Górny archtester Gentoo Infrastructure gentoo-dev Security 2013-10-09 17:27:22 UTC
Pacho, can you reproduce this? Because it builds fine for me with the same flags, portage, Python versions...
Comment 9 Pacho Ramos gentoo-dev 2013-10-09 17:40:19 UTC
Me not, I always run testing portage, but on a mostly stable system (apart of gnome/systemd...) :/
Comment 10 David Mohr 2013-11-19 16:29:57 UTC
I have the same problem with pygobject-3.2.2-r1 (and portage-2.2.7).

On another machine pygobject-3.2.2-r1 installed just fine on the 7th (at that point portage-2.2.7 was already installed), but now it fails to recompile as well.

The error is exactly the same:
Traceback (most recent call last):

Comment 11 David Mohr 2013-11-19 17:52:39 UTC
I can't figure out what changed from the last time it was compiled: I checked the dependencies, automake, autoconf and everything is older than pygobject. I even reverted the eclass that changed since then, but compilation still fails...
Comment 12 Greg Trigg 2014-01-07 12:27:16 UTC
The evil patch worked for me.  Any way we can get it added to an "-r1" ebuild?
Comment 13 Guenther Brunthaler 2014-02-05 07:19:13 UTC
Same problem here (amd64, too).

And the "evil patch" also solved the problem for me. Thanks, man!
Comment 14 Frederico 2014-03-06 14:44:38 UTC
The same here with pygobject-3.2.2-r1 and portage-2.2.7.
