Does anyone else notice extremely poor performance...

10/27/2020, 6:16 AMDoes anyone else notice extremely poor performance of IntelliJ IDEA when editing kotest files? All versions I've tried. I'm not sure what it is about the kotest files that it doesn't like...

10/27/2020, 6:56 AMYes, it’s brought up every once in a while. It’s a Kotlin/IJ thingy, sadly. Afaik the only thing we can do for now is submit a ticket on youtrack and hope the issues are resolved in new Kotlin releases

10/27/2020, 7:05 AM😢 I'll raise a ticket with the data I have
rpillay
10/27/2020, 7:05 AMThanks!

10/27/2020, 1:53 PMI do believe there's a ticket available

10/27/2020, 1:53 PM@sam do you have the link easily?

10/27/2020, 1:57 PMI think Jetbrains folks encourage to just create tickets regardless, and they’ll figure out if it’s a duplicate that needs to be merged

10/27/2020, 1:58 PMI think there are several tickets floating about
sam
10/27/2020, 1:58 PMI don't suffer from this issue myself, but I don't have 1500 line test files. Some things I've heard are slow in kotlin are lots of type parameters

LeoColman
10/27/2020, 2:04 PMI don't suffer with this either. My biggest test class is about 600 lines long

sam
10/27/2020, 2:04 PMKotlin can certainly be slow in the IDE in places but that's in normal files
sam
10/27/2020, 2:05 PMI read somewhere that 1.4.20 is supposed to be much faster
l
LeoColman
10/27/2020, 2:08 PMI read the same about 1.4.10 and 1.4.0

10/27/2020, 2:09 PMWell I just opened one of my specs, 350 lines: 6 seconds to even render the file, then another 12 seconds to analyze it

10/27/2020, 2:10 PMIf you uninstall the kotest plugin does it render any faster (I assume not, just like to rule things out)
w
wasyl
10/27/2020, 2:17 PMNon-scientifically: it does seem faster, but I’m not eager to jump to conclusions. If I find some time I’ll try to profile a bit, see if there’s any measurable impact
s
sam
10/27/2020, 2:17 PMlike 6 seconds down to 2 seconds faster
sam
10/27/2020, 2:18 PMor 6 seconds down to 5 seconds faster
w
wasyl
10/27/2020, 2:23 PMOh sorry, like initial 6 seconds to load was roughly the same (but also varied wildly), but then 12s down to ~6s for analysis
s
sam
10/27/2020, 2:23 PMSo the plugin is adding time to analyze - how big is the file
w

10/27/2020, 2:26 PM350 loc, 16 `describe`s, 29 `it`s. But also has utilities:
Copy code
private suspend fun DescribeScope.whenTimeAdvancesBy(duration: Duration, block: suspend DescribeScope.() -> Unit) =
describe("when time advances by $duration") {
Dispatchers.testMainDispatcher.advanceTimeBy(duration)
block()
}s

10/27/2020, 2:29 PMI'll spend some time next week looking over the plugin to see if it's doing anything silly

10/28/2020, 4:38 AMMy tests aren't even that big or complex. I have one that's about 600 lines long. WordSpec, the most complex bit being that its taking in 6 generators in the checkAll function
rpillay
10/28/2020, 4:38 AMyet the performance is terrible
rpillay
10/28/2020, 4:40 AMeg.
Copy code
checkAll(Arb.string(), Arb.string().orNull(), Arb.string().orNull(), Arb.string().orNull())s
sam
10/28/2020, 4:51 AMif you comment that out what happens
r
rpillay
10/28/2020, 7:09 AMa 2 minute naive test (just commenting them all out and editing) returns IntelliJ to normal responsiveness
rpillay
10/28/2020, 7:10 AMI'm going to try refactoring this to use checkAll, but with only 1 parameter and see what happens
