Test performance regression in `UnicodePlots` with julia `1.11.0-alpha2`

[t-bltg]

I have a little test case used to monitor allocations regression and runtime performance in UnicodePlots CI (with some tolerance): https://github.com/JuliaPlots/UnicodePlots.jl/blob/main/test/tst_io.jl#L67-L69.

It's been working flawlessly since julia 1.6 and up-to julia 1.10.2, but since 1.11.0-alpha1 there seems to be a massive regression in time performance (8ms vs 0.3ms before) and slightly more allocations (500kB vs 356kB before), resulting in CI failure such as the following:

Can you profile it? Potentially fixed by JuliaLang/Pkg.jl#3823.

[t-bltg]

Thanks, running from the REPL doesn't regress locally, so you are probably right about JuliaLang/Pkg.jl#3823 !
I'll keep an eye on the next alpha or beta version of 1.11.0 then ...

using UnicodePlots
let p = heatmap(collect(1:30) * collect(1:30)')
  string(p; color = true)  # 1st pass - ttfp
  GC.enable(false)
  stats = @timed string(p; color = true)  # repeated !
  GC.enable(true)
  @show stats.bytes stats.time
end
# stats.bytes = 372920 stats.time = 0.000797776 (1.11.0-alpha1)
# stats.bytes = 355704 stats.time = 0.000682859 (1.10.2)

[t-bltg]

AFAIK this is still broken on 1.11.0-alpha2, running pkg> test UnicodePlots locally.

Yeah a profile would help here. You'd need to do it in the test suite itself

[t-bltg]

Added in the test suite:

p = heatmap(collect(1:30) * collect(1:30)')
string(p; color = true)  # 1st pass
GC.enable(false)
Profile.init(; n=10^9, delay=1e-7)
Profile.clear()
@profile string(p; color = true) 
Profile.print()
GC.enable(true)

Here is the Profile output on 1.10.2:

Thanks. Can you try with and without coverage on? (It looks like it's currently on in the above cases?)

[KristofferC]

If I put

using UnicodePlots, Test 
using BenchmarkTools
p = heatmap(collect(1:30) * collect(1:30)')
@btime string(p; color = true) 

in runtests.jl I cannot observe a difference if I run with Pkg.test or including it. Did you manage to repro it at all locally?

Are you on 1.11.0-alpha2 ?

(UnicodePlots) pkg> test fails locally

This also fails locally:

using TestEnv
TestEnv.activate()
include("test/runtests.jl")

[IanButterworth]

Given coverage is on on CI, I tried moving the load of UnicodePlots last in case it was due to #53457

but it still fails JuliaPlots/UnicodePlots.jl#375

So doesn't seem to be due to that coverage issue.

And you're reporting it locally without coverage turned on, I believe

@IanButterworth, thanks for trying this !
