 |
|
When I call emerge:
That is, I just get a python prompt  . The same happens if I do # python /usr/bin/emerge.
But, if I do this:
| Code: |
nyu ~ # cat /usr/bin/emerge|python
emerge: the other white meat (command-line interface to the Portage system)
<blah>
|
The same happens with other tools.
I have no idea what's going on or what to try at this point. |

I can do that, sure.
But the mistery would remain unsolved, that way  |

| Posted: Fri Dec 07, 2007 11:28 pm Post subject: emerge exits to python shell when using kernel 2.6.23-r3 |
|
|
This sounds strange I know.
When I switched to kernel 2.6.23-gentoo-r3 from 2.6.22-gentoo-r9 emerge stopped working, exited to python shell. Something lke:
emerge -s ltsp
>>>
And by only changing back to kernel 2.6.22-gentoo-r9 everything works OK. And other python scripts stopped working too (eg. klive).
I asked on #gentoo, but nothing, filled a bugreport (https://bugs.gentoo.org/show_bug.cgi?id=201621) but was redirected to forums.
Does anyone have any ideas?
Thanks in advance |

Try diff-ing your 2.6.22-gentoo-r9 config with your 2.6.23-gentoo-r3 config and see if anything stands out.
When you boot to 2.6.23-gentoo-r3 watch the console for unusual messages, perhaps it has something to do with your file system. |

When I had this problem, I tried to rebuild 2.6.23-r3 with 2.6.22 config which I copied from /proc/config, and nothing changed.
I reemerged python and nothing.
I did and emerge -e system, and nothing changed. Nothing on revdep-rebuild
I tried 2.6.24-rc2-mm1 and nothing 
I used the system and tested it for hours with 2.6.23-r3 and only python scripts had troubles (Klive, emerge, revdep-rebuild).
Nothing in /var/log/messages
No errors in dmesg.
System is using CFLAGS="-O2 -march=nocona -pipe" and x86 arch.
Only thing that may be considered unstable is my / which is reiser4.
dev-lang/python: 2.4.4-r6
I don't understand how a different kernel can have influence on python.
Now my strategy is to wait and hope that this will get automagically resolved some time in future
Thanks

I don't know if it has any bearing on your particular issue, but I did run into some very strange behaviors when using a certain version of the reiser4 driver. Operations involving files of a certain size and/or its multiples failed with odd errors. If you have a spare box or a virtual machine handy, you might try duplicating your system with ext3 instead of reiser4 to see if the problem persists.

| Might be worth to investigate this with strace or FEATURES=python-trace to find out where it goes wrong. |

That's a little above my head.

I had no errors in my /var/log/messages, but I thought I'll try it if I don't think of something else. But I can only do it on weekend nights

|
|
This problem has been isolated to a recent reiser4 bug; booting an older kernel without some reiser4 patch I was testing fixed it.
If any of you experience such problems, you can go back to 2.6.22.x with the reiser4-2.6.22-2 patch and it'll work fine, the current 2.6.23 patch has this problem (and it's isolated to a patch I was helping test on 2.6.22, so hopefully it'll be fixed soon)
Cheers. |

Looks like this is the bug introduced in reiser4 after 2.6.22
Will keep you posted
thanks for your help |

To clarify, is it that only emerges with certain options and certain python scripts exhibit this behavior with the new kernel? |

All python scripts I tried (emerge -s,-p etc. revdep rebuild and Klive on startup)
