<K-ballo> is partitioned_vector_view killing clang now?
<hkaiser> K-ballo: is it?
<hkaiser> K-ballo: nah
<K-ballo> > clang: error: unable to execute command: Killed
<hkaiser> cicleci is very unstable recently, constantly fails at some (random) place
<K-ballo> PLEASE ATTACH THE FOLLOWING FILES TO THE BUG REPORT:
<K-ballo> Preprocessed source(s) and associated run script(s) are located at:
<K-ballo> clang: note: diagnostic msg: /tmp/partitioned_vector_view-a0ec68.sh
<K-ballo> clang: note: diagnostic msg: /tmp/partitioned_vector_view-a0ec68.cpp
<K-ballo> then later circle ci kills the build because partitioned_vector_view_iterator takes forever
<hkaiser> I had a lot of different problems with circleci
<hkaiser> could be running OOM
<K-ballo> sounds like partitioned_vector_view is just too heavy compile-time wise
<hkaiser> could be
<hkaiser> #2806 could help with that
<zao> How much memory and /tmp do they have? :)

<hkaiser> K-ballo: is there a way to conditionally delete a (member-) function?
<hkaiser> i.e. make a type non-default-constructible conditionally
<K-ballo> yes
<K-ballo> make it fake dependent, via defaulted template argument
<K-ballo> works only for default-constructible, not the other special members
<hkaiser> K-ballo: so disable_if the default constructor?
<hkaiser> doesn't that mean that it 'disappears' and the compiler will generate one instead?
<K-ballo> sure, or overload and =delete
<K-ballo> default constructor gets suppressed by the existence of any other constructor iirc
<hkaiser> ahh yes
<hkaiser> make sense - thanks
<K-ballo> for having an explicitly =deleted overload one has to use the non-type kind of enable_if

<hkaiser> K-ballo: btw, that commit you referenced never made it into the main code base :/

<K-ballo> I was looking for an LWG resolution, but didn't think it was worth the metaprogramming trouble for us
Matombo has quit [Ping timeout: 240 seconds]
<K-ballo> I kept it around just in case one day we happen to need it
<hkaiser> I might need it now ;)
<hkaiser> why do you use is_constructible there and not is_default_constructible?
<K-ballo> uh, you must be in some nasty situation
<hkaiser> well, @krivenko asked for non-default-constructible types as action arguments
<K-ballo> is_constructible is the base one, all other constructible traits are implemented in terms of it, and some older libs didn't have the derived ones
<hkaiser> ahh, ok
<K-ballo> I wouldn't write it exactly like that today
<K-ballo> in particular I'd use `typename Dependent = void, typename Enable = typename enable_if<Cond, Dependent>::type>`
bikineev has joined #ste||ar
<K-ballo> rather than that awkward `is_constructible<Dummy>` check
<hkaiser> nod
<hkaiser> I got that already ;)
<hkaiser> also, should't the Ts types be decayed?
<K-ballo> no
<K-ballo> the tests would fail if they were
