12:59 <lembron> so, i´m inide a gitlab-omnibus rails-shell or so -- i do have command-history with arrow-up/down, how can i print all of them as a list? - the docs mention "puts Readline::HISTORY.to_a" but that is nil.

13:03 <lembron> hm, seems that package is called "Reline" not "Readline"? - Reline::HISTORY.to_a seems to have my data :)

14:26 <lembron> and why would `json_data = File.read('/tmp/8mb.json')` take a good 2 minutes.... - its not even decoding there isnt it but still slow as balls

14:56 <adam12> lembron: Is the file 8mb?

14:57 <lembron> yeps, [{bla},...] stuff with 24k elements

14:58 <adam12> That's a good question. I don't normally ready large files like that, but try to prefer streaming them instead.

14:58 <lembron> guess i should also move that off /tmp - not that some systemd-shim is hanging there.. - but it more looks like "its trying to echo(and then cut off) is the baddy"

14:59 <lembron> reaming or whatever is all irrelevant too i guess - just using that to hacky-irb tryout some lines of gitlab-code to track down a bug...

15:01 <lembron> speaking of bug: root = Gitlab::Json.parse(json_data) then root.length / root.count say (correctly) 24731 -- but `root.each do |degradation| printf "." end` prints out only 3503 dots

15:03 <adam12> So a quick test - File.read is fast, but IRB is trying to probably display the json_data variable and that's slow. If you're still doing the json_data = ... call, try adding a semi-colon to the end.

15:03 <adam12> json_data = File.read('/tmp/8mb.json');

15:05 <lembron> "trying to display the json_data variable" sounds about right yea - a ";" does nothing (also still prints the obj)

15:06 <adam12> Weird.

15:08 <lembron> `but `root.each do |degradation| printf "." end` prints out only 3503 dots` <- ignore what i said there... i may have just found a trace... --- the actual code has a `break unless codequality_report.valid_degradation?(degradation)` in there - if i remove that break i do get 24k .´s printed - "but it also never finishes" (and i have to Ctrl+C it o.O

15:12 <lembron> so Q) 'how is that that each doesnt finish there?' - MUST one break inside them? (no cue of ruby ;D)

15:22 <lembron> ;) seems i did find the element causing my break, getting to an error on the schema-validator 3 steps down now

19:15 <lembron> adam12 just to follow up on that - the ";" idea wasnt wrong, but it needs something else after - so "...; nil" and booms, the File.read is as instant as it would be expected ;D

19:18 <adam12> lembron: Oh that's interesting. I've never seen the need for the `;nil` but maybe we have different irb versions.
