Comment 1 Martin Mokrejš 2013-10-13 21:10:54 UTC
Ah, maybe is a portage issue?

With emacs I got:

make[2]: Leaving directory `/mnt/1TB/var/tmp/portage/app-editors/emacs-24.3-r2/work/emacs-24.3/lisp'
if test "no" = "yes"; then \

  ln temacs bootstrap-emacs; \
else \
  `/bin/pwd`/temacs --batch --load loadup bootstrap || exit 1; \
  test "X/sbin/paxctl" = X || /sbin/paxctl -zex emacs; \
  mv -f emacs bootstrap-emacs; \

With seamonkey I got:

There is a free space on the /mnt/1TB filesystem, the filesystem did not crash per dmesg, so I don't know why is this. Why other packages did not choke with a similar message I don't know either. ;)
Comment 2 Tom Wijsman (TomWij) (RETIRED) gentoo-dev 2013-10-13 23:36:00 UTC
Probably, I think the parent folders need to have proper permissions too with recent versions of Portage; could you check that?

Mine are Access: (1777/drwxrwxrwt)  Uid: (    0/    root)   Gid: (  250/ portage)

So, why does not emerge check this upon startup?

None of the following helped:
chown root.root /mnt/1TB
chgrp portage /mnt/1TB


chmod g+rwx /mnt/1TB did help (so portage group could write).

# emerge --version

Comment 4 Tom Wijsman (TomWij) (RETIRED) gentoo-dev 2013-10-14 23:33:15 UTC
This catches unaware people; so yes, we should have Portage check this early on to avoid wasting time or at least guide them to check this as part of the error.
Comment 5 Stefan Briesenick (RETIRED) gentoo-dev 2015-07-14 14:35:04 UTC
something is utterly broken. This problem exists in many packages now. Not all, but many.

Any hints which packages to downgrade, so I have a working environment again for the time being?
Comment 6 Stefan Briesenick (RETIRED) gentoo-dev 2015-07-14 14:37:03 UTC
huh, this is an very old bug. Ok, I have to say, that I have that problem NOW, not in the past. Any hints to fix it?
Comment 7 Zac Medico gentoo-dev 2015-07-14 16:42:10 UTC
You can try FEATURES="-userpriv" to see if that helps.
Comment 8 Stefan Briesenick (RETIRED) gentoo-dev 2015-07-24 15:18:28 UTC
seems to work... :-/

Comment 9 Zac Medico gentoo-dev 2015-07-24 16:14:34 UTC
It looks like you need to ensure that all of the parent directories of PORTAGE_TMPDIR have +rx permissions for the portage user. If the +r bit is missing, then apparently it breaks an assumption in the perl-core/Encode build system (involving ExtUtils::MakeMaker).
Comment 10 Mikle Kolyada archtester Gentoo Infrastructure gentoo-dev Security 2015-07-24 16:26:41 UTC
Do not need to CC perl there, it looks like user side issue not a perl one:)
Comment 11 Zac Medico gentoo-dev 2015-07-24 16:28:04 UTC
I have /usr/lib64/perl5/5.20.2/ExtUtils/ from dev-lang/perl-5.20.2, and the relevant code succeeds for me if I don't have read access to a parent directory:

perl -e 'use Cwd qw(cwd abs_path); my $pwd = cwd(); print "$pwd\n";'
Comment 12 Zac Medico gentoo-dev 2015-07-24 16:31:56 UTC
(In reply to Stefan Briesenick from comment #6)

What versions of dev-lang/perl, virtual/perl-ExtUtils-MakeMaker, and/or perl-core/ExtUtils-MakeMaker do you have? What are the permissions of all the parent directories of PORTAGE_TMPDIR?
