do you plan to look into implementing the emplace stuff for future or should I plan to adding it?
<hkaiser>
K-ballo: ^^
<K-ballo>
I planned to but it may be a while, feel free to go for them
<hkaiser>
K-ballo: ok - you said you already implemented that, do you still have that code?
<K-ballo>
unlikely

Does anyone know of pitfalls associated with have static clients? I'm getting a pure virtual method called runtime errror.
parsa has joined #ste||ar
<jbjnr>
calling a pure virtual is usllay becuase you've cast a pointer to a base instead of a derived class. Any chance you have a typoe somewhere. Though if it's a client object it might be something bad happening deep inside hpx (guessing randomly)
<jbjnr>
(a clientn being static - I don;t know what that would mean for the pointer - as long as you dynamic cast it -it ought to be ok I would have thought).
<mbremer>
I don't think I'm doing any casting...
<mbremer>
Actually lemme see, if it is what I think it is a simple MWE should be pretty easy, and if not, then it's probably something on my side anyway :)
<mbremer>
I guess, I'm just worried the client outliving the hpx::finalize call
<mbremer>
But let me see, that should be an easy thing to check

EverYoung has quit [Remote host closed the connection]
<mbremer>
SO this throws the same error, I'm seeing. And if I remove L39-L40, my issues go away
<heller>
hmm
<heller>
and if it is non static, all is well?
<heller>
try to do a A::client = Client() before calling finalize
<heller>
i think the error is exactly for the reason you expected ... the client is attempted to be destroyed after finalize has been called
<mbremer>
Yeah, that seems to fix it
<mbremer>
kk, that seems like an easy enough fix.
<mbremer>
Great, thanks @heller! I also just wanted to make sure that I wasn't doing anything too illegal from an Hpx point of view
<heller>
no
<heller>
the problem there really is the lifetime of the static
EverYoung has quit [Remote host closed the connection]
EverYoung has joined #ste||ar
<mbremer>
yeah, it's probably bordline programming practices :) But I feel like I need to initialize the client from something non-trivial so there's a certain symmetry into having to reset it at the end
