Hi, I'm using rspec with a rails project. When I do "expect(response).to be_successful", what does the "be_successful" exactly do? Does it check for the response status? Because I mainly do: "expect(response).to be_successful; expect(response).to have_http_status(:ok)" but I don't know if "expect(response).to have_http_status(:ok)" is needed here...

kkoomen: so the first thing to understand is that in rspec, be_foo just calls .foo? on the object and looks for a truthy return value. So this is essentially raise unless response.successful?. Now where does successful? come from? response is a ActionDispatch::TestResponse, let's take a look at it:
<jhass>
so be_successful does a range check on the status code, your second expectation then narrows it down to just being equal to 200
<jhass>
making be_successful kind of redundant, yes

Any ideas? It's drivin

uhm, context?
kristian_on_linu has quit [Remote host closed the connection]
<jhass>
fritzroy15: more like browser <=> nginx <=> ruby processs (puma <=> rack app (sinatra <=> your code))
<jhass>
socket IO is bidirectional and rack is a middleware architecture
<androi>
i think it doesn't matter.. put the inner class outside of the outer one and i get the same result
<jhass>
androi: severley lacking context here :)
<androi>
in general. is there any purpose to define a class in a class?
<burgestrand>
androi no they have no connection
<burgestrand>
androi for organizational purposes yes
<jhass>
Class < Module, so they can act as namespace just like a module would
<androi>
ok
<androi>
and invoke it then with class1::class2 ?

havenwood: I need your memory again. Experimental library that would cache Ruby AST. Not Bootsnap. I thought it came from ko1 but not finding it. Does it ring a bell? I feel like you've linked it before.
<havenwood>
adam12: I'd still love to see RubyGems compile binary files automatically on gem install then use those if checksums match.
<havenwood>
adam12: Better yet, integrate with `ruby` and `gem` fully like Elixir does with precompiling to IR bytecode.

Running the code in that ^ gist shows some interesting errors in some gems when producing bytecode.

havenwood: I'd like to see bits of bootsnap make it's way back into MRI. Maybe just even the $LOAD_PATH optimization stuff but the bytecode caching stuff is of interest too.
<adam12>
I'm in a constant battle with one of my apps to drop boot time, and it only gets worse.
<havenwood>
adam12: The bytecode caching makes a pretty large difference.
<havenwood>
adam12: Roda app or Rails or pure Ruby?
<adam12>
havenwood: Roda app.
<adam12>
havenwood: A lot of it is is azure dependencies (which I've talked about before). I end up lazy loading them wherever possible, but there's still time lost in places.
<adam12>
havenwood: In some apps I use Zeitwerk with much success, if the folder structure is Zeitwerk friendly. I'm experimenting with dry-system in others but for overall boot time there's no savings (just in running tests / maybe booting a console).
<havenwood>
adam12: Ah, I was curious if Zeitwerk would help.
banisterfiend has quit [Ping timeout: 240 seconds]
<adam12>
havenwood: In this case it might, but once it has to load those large dependencies all bets are off.

havenwood: And until recently it was fairly rigid in folder structure, and this app has some legacy where files dont' define exact matching constants.

if your application is strictly CPU bound, the returns are probably little. But when it comess to IO bound workloads, very much so

jhass, i don't think that would apply to these concurrent data structures, but yeah as a general principle i see what you mean
chalkmonster has joined #ruby
<jhass>
well maybe I didn't get your question. Since you mentioned GIL/GVL I considered the question to be of performance. concurrent-ruby mainly provides varying levels of patterns and abstractions that make writing concurrent programs easier. That doesn't make them influence the workloads though

jhass, here's my dilemma. i'm doing the following: "memo = {} ; Parallel.map(array) { |obj| resolve(obj, memo) }", where memo is a hash for memoizing all the results. all the "obj" files are top-level dependencies. i want to have a copy of memo for each process, and then at the end merge them all into one. is there any way to do that with ruby's Parallel lib?

(doesn't help that that parallel gem seems to have practically no documentation)
