Description Mike Gilbert gentoo-dev 2016-04-10 18:14:03 UTC 
It would be nice if portage would run the pkg_pretend phase in parallel jobs.

For example, when installing KDE/Plasma 5, every ebuild which inherits kde5.eclass runs the kde5_pkg_pretend function. This takes a few minutes to complete for around 60+ packages.
Comment 1 Zac Medico gentoo-dev 2016-04-10 21:43:16 UTC 
Some notes:

* build log should be combined with the pkg_pretend log (they are currently separate because the build dir is destroyed in between)

* parallel-fetch tasks should be started at the same time as pkg_pretend
Comment 2 Zac Medico gentoo-dev 2020-10-26 17:29:13 UTC 
The pkg_pretend phases run in a coroutine since bug 710432, so running them in parallel should not be much work.
Comment 3 Zac Medico gentoo-dev 2021-06-23 00:08:31 UTC 
The UI will look very close to the existing emerge --jobs UI.
Comment 4 Zac Medico gentoo-dev 2024-07-29 04:14:30 UTC 
We need pkg_pretend scheduling to be aware of package fetch status (for retry) as described in bug 936287 comment #2.
