Bug 142279 – emerge --clean fails on error with string error with os.stat()

• Status: RESOLVED FIXED
• Product: Portage Development

[Description Ben McIlwain 2006-07-31 06:53:31 UTC]

I type emerge --clean and I get a bunch of stuff like the following:
--- !mtime obj ...
Then finally the error message comes up:

Traceback (most recent call last):
  File "/usr/bin/emerge", line 3245, in ?
    if 1 == unmerge(myaction, myfiles, raise_on_missing=False):

    statobj = os.stat(obj)

I think you've got a corrupt /var/db/pkg/*/*/CATEGORY file for whatever package it was trying to unmerge.  If that's the case, you can remove the directory containing the corrupt file and reinstall the package.

In svn r3382, I've added some validation of the CATEGORY file and a warning message.

So anything left to do here for us?

*** Bug 163485 has been marked as a duplicate of this bug. ***

[Comment 4 Zac Medico 2007-01-23 21:45:58 UTC]

In svn r5763 I've added null byte corruption detection for CONTENTS since that seems to be the cause of the traceback in bug #163485.

Thank you.  I hate to say it, but Linux isn't perfect and sometimes crashes and sometimes even journaled filesystems break things :)

This has been released in 2.1.2-r3.
