Bug 564988 – sys-apps/portage: skip metadata-transfer when sync fails or server timestamp has not changed

• Status: RESOLVED FIXED
• Product: Portage Development

[Description Zac Medico 2015-11-06 07:32:26 UTC]

The metadata transfer and hooks can be relatively time consuming, so they should be skipped when sync fails or the server timestamp has not changed.

There's a patch in the following branch:

Some people might be working under the assumption that emerge --sync will *always* call their hook, in order to trigger some system administration tasks that have little or nothing to do with the sync operation itself. It's impossible to speculate how many people might be relying on this sort of behavior.

So, I'll think about exposing an environment variable to the hooks which will allow them to decide if anything relevant has changed.

It should be safe enough to just skip the metadata transfer.
