from irc after me constantly crying about how slow it is to merge binpkgs: 17:35 < zmedico> Zero_Chaos: we could add a FEATURES setting to disable bash invocations for pkg_* phases that are not in DEFINED_PHASES 17:36 < Zero_Chaos> zmedico: is that even remotely safe? 17:36 < zmedico> Zero_Chaos: yes, except that any user hooks in bashrc won't be executed for those phases that are skipped 17:37 < Zero_Chaos> zmedico: can you explain to someone who is just a little dumber than you just explained that to? 17:39 < zmedico> Zero_Chaos: well, with existing behavior, /etc/portage/bashrc and the profile's profile.bashrc files are sourced/executed for every phase, even if they do nothing 17:39 < Zero_Chaos> zmedico: but if we are skipping the phase it also skips sourcing bashrc for that phase? that seems pretty safe. 17:39 < zmedico> Zero_Chaos: they can execute code in global scope, or define user phase hooks like pre_pkg_setup, post_pkg_setup, and so on 17:40 < Zero_Chaos> zmedico: so do you need a bug for FEATURES=make_faster_for_zero ? 17:40 < zmedico> Zero_Chaos: yeah, should be very safe generally. 17:40 < zmedico> Zero_Chaos: yes, please do. 17:40 < zmedico> FEATURES=bashrc 17:41 < zmedico> well 17:41 < zmedico> do you want to disable bashrc entirely? 17:41 < zmedico> or just when the phase is not in DEFINED_PHASES? 17:41 < zmedico> we could have separate settings 17:42 < zmedico> also, theres /etc/portage/env/$CATEGORY/... 17:42 < zmedico> those are a special kind of bashrc 17:42 < zmedico> could have a separate knob for those as well 17:42 < Zero_Chaos> I use the profile.bashrc, it's important that for the phases which run that it parses since it sets MAKEOPTS 17:42 < Zero_Chaos> well actually for my build system I override that so it's not *that* important 17:43 < zmedico> it might also make sense to vary these settings for binpkgs 17:43 < zmedico> since the bashrc stuff might matter less for them 17:44 < Zero_Chaos> zmedico: I'll leave that to you, and obviously I'm willing to test whatever you want. My main complaint here is that binpkgs seem WAY slower than I feel they should be.
I'm not convinced this is going to be what's slowing things down for you, but profiling results would help. You can easily bail out early in /etc/portage/bashrc if you want, or just don't define one at all, right?
