Bug 330997 – IOError: [Errno 11] blocks all emerge after upgrading (python and/or socat)

• Product: Gentoo Linux
• Status: RESOLVED DUPLICATE

[Description Mike Hammill 2010-08-03 09:29:17 UTC]

After upgrading to dev-lang/python-2.6.5_p20100801, net-misc/socat-1.7.1.3, and dev-lang/python-3.1.2_p20100801 on x86_64 I am unable to emerge any longer.  Now emerge always bombs on:
IOError: [Errno 11] Resource temporarily unavailable


Reproducible: Always

Steps to Reproduce:
1. upgrade to python-2.6.5_p20100801, net-misc/socat-1.7.1.3, dev-lang/python-3.1.2_p20100801
2. try any new emerge (you may reboot, env-update, blah, blah, blah, before hand, it does not help)
3. emerge bombs

Actual Results:  
Example:
# emerge -aD tmux

These are the packages that would be merged, in order:

Calculating dependencies... done!
[ebuild  N    ] app-misc/tmux-1.2  USE="-vim-syntax" 

Would you like to merge these packages? [Yes/No]

  File "/usr/lib64/portage/pym/_emerge/SpawnProcess.py", line 151, in _output_handler
    buf.fromfile(files.process, self._bufsize)


Expected Results:  
Emerge not broken.

This is not going to be fun to fix, I have a feeling!

My copy/paste of the bomb message missed the very last line:

IOError: [Errno 11] Resource temporarily unavailable

[Comment 3 Mike Hammill 2010-08-03 09:35:07 UTC]

The area in question in SpawnProcess.py
try:
	buf.fromfile(files.process, self._bufsize)
except EOFError:
	pass
