 |

Hi,
i decided to upgrade python on one of my servers from 2.4 to 2.5. After the upgrade glsa-check -l fails with:
| Code: |
spike ~ # glsa-check -l
[A] means this GLSA was already applied,
[U] means the system is not affected and
[N] indicates that the system might be affected.

So i tried python-updater, recompiling expat version 2. and 1., removing python from old slot, recompiling gentookit,...
Nothing seems to help with this problem. What else can I do?
Let me know if you need more info. Thank you for your time. |

According to my system, the file is provided by python itself, and I can't see any USE flags relating to xml.
I would avoid any switching between expat 1 and 2 because of the ABI breakage expat causes. You should be sticking to the stabl version 2 now.
My python 2.5 USE flags are: berkdb gdbm ipv6 ncurses readline sqlite ssl threads -bootstrap -build -doc -examples -tk -ucs2 -wininst
I would check your USE flags against those - particularly ensure that you don't have bootstrap or build enabled (these 2 flags should never be enabled by users). Then try re-emerging python 2.5 |

Hi,
I'm on expat 1. I tried installing expat 2 just to make sure using version 1 isn't a problem. The error persisted.
I also did reemerge of python 2.5, but the problem is exactly the same.
| Code: |
spike ~ # emerge python -av
These are the packages that would be merged, in order:

Use eselect-python and set python to 2.5 (might have to emerge eselect-python)
Run python-updater
Run revdep-rebuild -X -i
emerge --oneshot libxml2 libexpat
revdep-rebuild -X -i again
is what I'd probably try. |

Having the same issue here. I've run a revdep-rebuild and it didn't pick up anything. I also reemerged libxml2 and =expat-1.95.8 but glsa-check still bombs out:
| Code: | # glsa-check --list affected

| I also tried the upgrade to expat-2.x, and it didn't solve anything. |

| I think I solved things. It looks like there is a missing dependency for pyxml. Emerge dev-python/pyxml and the error goes away. |

LOL!
I gave up in this for now. I guess you solved my problems.  Sometimes is best to wait.
Thanx.
Also make a bug report for missing dependency. |

I've been running glsa-check in cron.daily for years, and just got bit by this, this morning. Yesterday I did a general update, so that's probably what broke it, but gentoolkit wasn't one of the packages I updated. This morning I found that pyxml was not installed on that system, and installing it appears to have fixed the problem.
Any idea of what happened?

| The "usual" problems between the standard python xml modules and pyxml (sometimes pyxml solves the problems, sometimes it creates them) that have existed for years. |

| Someone should really fix this dependency. |
