Description Ostashevskyi Viktor 2012-07-06 11:58:18 UTC

I'm using sys-apps/portage-2.1.11.15

If python-mhash is not installed I have problems with following packages:

app-office/libreoffice-3.5.5.3
app-emulation/virtualbox-4.1.18

Merging hangs during checksum checks and emerge process eats 100% CPU. I was waiting for 10-15 min, but no progress.

Confirmed on two different boxes with different CPUs/configuration.

Installing python-mhash solves problem.

I think that is critical as it stops user from emerging some packages without providing any failure information.

I tested with VirtualBox-4.1.18.tar.bz2 (73688436 bytes) here and it took about 20 minutes.

So, I've updated to portage dependencies to required python[ssl] or python-mhash.

Here's a fix to skip whirlpool digest checks when they're unaccelerated:

This is in 2.1.11.6 and 2.2.0_alpha117.
