Description J. Paul Reed 2011-01-16 01:09:35 UTC
When doing an |equery b something|, I get a screen-full of:

!!! Parse error in '/var/db/pkg/app-shells/tcsh-6.12-r2/CONTENTS'
!!!   line 81: Unrecognized CONTENTS entry
!!! Parse error in '/var/db/pkg/app-text/docbook-dsssl-stylesheets-1.77-r2/CONTENTS'

The command eventually does complete and give me output.

I did a bunch of searching, and the common explanation is that "Your CONTENTS file is corrupted; check your hard drive."

However, the common theme among these lines is that they're "sym" lines, and it looks like the format of the sym line changed in portage's vartree dbabi. (This Gentoo installation is probably... 5 or 6 years old at this point, so it's not surprising that I'd run into this.)

I don't have enough context to be sure, but it looks like the problem might be related to?;a=commitdiff;h=7295411a389c89418b460c059e2a222475dd1ec4;hp=b9226939dc1b50d7b77e8ac99112d468b2140b52

The files that have problems have the following style of sym CONTENTS lines:

sym /usr/lib/ -> (41471, 78241L, 770L, 1, 0, 0, 12L, 1064292767, 1064292767, 1064292767)

It looks like the new style is:

sym /lib/ -> 1117594156

What is clear is that the current sym regex (;a=blame;f=pym/portage/dbapi/;h=9f75da21b61fcd3dbe4c69645d413d5925660cd2;hb=HEAD#l1199) will fail to parse the old style, since it has commas in it.

Is there a portage command to convert old-style sym entries to new-style, and I missed it? It looks like the new style only cares about the ctime (or mtime?), not the other info that used to be there.

Reproducible: Always

Steps to Reproduce:
Difficult to describe; you need an older-style CONTENTS file to repro this problem. (I can attach one if it helps.)

Comment 1 Zac Medico gentoo-dev 2011-01-16 01:47:31 UTC
Re-assigning since the problem is in the portage API.

I would have kept support for the old format if I had known that it was still around. I see that openjade didn't have an version bumps between 2003 and 2010, so that explains why its CONTENTS is so old.
Comment 2 J. Paul Reed 2011-01-16 11:09:54 UTC
Yeah, as I mentioned, this Gentoo installation is pretty old (which says a lot about Gentoo! :-)

FWIW, this is actually a problem with more than a few packages on my system, apparently:
