Description Paweł Hajdan, Jr. (RETIRED) gentoo-dev 2013-09-20 03:52:24 UTC 
I was running repoman manifest for new www-client/chromium ebuild. Here's the result:

But the incomplete chromium-31.0.1626.0-testdata.tar.xz file was actually still left in /usr/portage/distfiles .

Shouldn't portage download to a temporary directory / under temporary file name first, and only rename to target name after successful fetch?

This will be solved by by the fix for bug 175612, using a temporary download file with a constant suffix, and atomic rename after the download is complete.
