[gentoo-dev] Manifest issues in the tree

[Kumba <kumba@gentoo.org>]

Lately, I've been running into an awful lot of manifest issues in the 
portage tree.  Not just on x86, but sparc and mips too.  For those that 
may doubt me, add "manifest strict" to FEATURES and see for yourself.

Where these issues are coming from is anyone's guess.  Probable suspects 
are those devs not using repoman to check ebuilds into the tree, or we 
might have some kind of corruption running around on the rsync servers, 
or there's some odd bug in portage.

To quote actual evidence, sys-devel/gettext, app-arch/zip, 
app-admin/mirrorselect, and app-admin/gentoolkit gave manifest errors.

on x86, gettext-0.12.1 gives this:
Calculating dependencies ...done!
 >>> emerge (1 of 1) sys-devel/gettext-0.12.1 to /
 >>> md5 files   ;-) gettext-0.12.ebuild
 >>> md5 files   ;-) gettext-0.11.3-r1.ebuild
 >>> md5 files   ;-) gettext-0.11.1.ebuild

!!! File does not exist: 
/usr/portage/sys-devel/gettext//gettext-0.12.1.ebuild

on sparc:
 >>> emerge (1 of 1) sys-devel/gettext-0.12.1 to /
 >>> md5 files   ;-) gettext-0.12.ebuild

!!! File is corrupt or incomplete. (Digests do not match)
 >>> our recorded digest: f1002900097f883163423147dce6d9d9
 >>>  your file's digest: b696d10b2ea72a2dc08b55020f8f79d7
!!! File does not exist: /usr/portage/sys-devel/gettext//ChangeLog

(mips gettext is not included as I already re-digested on that machine, 
and an rsync takes ~20mins)

Why these two differ on different machines, I'm not exactly sure on. 
Below are some other snippets between sparc, x86, and mips.



x86/sparc/mips app-admin/mirrorselect:
Calculating dependencies ...done!
 >>> emerge (1 of 1) app-admin/mirrorselect-0.6 to /
 >>> md5 files   ;-) mirrorselect-0.6.ebuild
 >>> md5 files   ;-) mirrorselect-0.3.ebuild

!!! File is corrupt or incomplete. (Digests do not match)
 >>> our recorded digest: 6d748dbe957886a5ca691637d94ec1b3
 >>>  your file's digest: 100d61a5fe0f28e65afbcad758984d6a
!!! File does not exist: /usr/portage/app-admin/mirrorselect//ChangeLog

In this case, the error is the exact same on all three machines.


x86 app-arch/zip:
 >>> emerge (1 of 1) app-arch/zip-2.3-r2 to /
 >>> md5 files   ;-) zip-2.3-r1.ebuild

!!! File is corrupt or incomplete. (Digests do not match)
 >>> our recorded digest: 3276fb2669785d06bfb6c2cec123521d
 >>>  your file's digest: f56548176b22628e4a08abadbcbad329
!!! File does not exist: /usr/portage/app-arch/zip//zip-2.3-r2.ebuild


on sparc:
Calculating dependencies ...done!
 >>> emerge (1 of 1) app-arch/zip-2.3-r2 to /
 >>> md5 files   ;-) zip-2.3-r1.ebuild

!!! File is corrupt or incomplete. (Digests do not match)

(masked on mips)

In these cases, two different machines report different md5sums and 
apparent errors in the manifest.


I suspect something similar will happen if one tried the same on 
gentoolkit, but this mail is long enough already, so I'll exclude it.

I've been running into these issues quite often, and I suspect several 
reasons.  In some cases, it seems like some people aren't using repoman, 
as I'll redigest and commit via repoman, and half an hour later, the 
manifest errors are gone after an rsync.  In other cases, like where two 
different machines report different errors in the manifests, I'm 
thinking either corruption on the rsync servers, or a bug in portage 
somewheres.

If someone wants to give this a shot, again, add "manifest strict" to 
FEATURES, and start emerging updates over the next few days.  You're 
bound to run into the same issues I'm seeing on multiple machines.

Ideas, thoughts?  Or am I just going insane?
