No method matching reprcontext

[tlienart]

I tried to use SnoopCompile with Franklin's tests today but the SnoopCompile.parcel(inf_timing) step failed with

MethodError: no method matching reprcontext(::Module, ::Core.TypeofVararg)
Closest candidates are:
  reprcontext(::Module, !Matched::Type) at /Users/tlienart/.julia/packages/SnoopCompile/qKfrD/src/parcel_snoopi.jl:178

parcel(tinf::Vector{Tuple{Float64, Core.MethodInstance}}) at parcel_snoopi.jl:228
top-level scope at snoop.jl:6
eval at boot.jl:369 [inlined]

what I did is simply

inf_timing = @snoopi include("test/runtests.jl")
pc = SnoopCompile.parcel(inf_timing)

A basic guess would be that SnoopCompile doesn't like the creation of module and evaluation of code within these temporary modules. But would there maybe be a way to skip this rather than fail? Or should I just have a simpler example for @snoopi than the full test suite?

thanks!

PS: maybe a workaround is to filter the result of inf_timing to remove things that throw off parcel? if so how would I do this?

Which branch are you on? Recommended is teh/subflames, which is just a tiny bit ahead of #192.

[tlienart]

I'll try this

Note: what I did for the moment is:

function snoopf!(v)
    remove = Int[]
    for i in 1:length(v)
        try; SnoopCompile.parcel(v[i:i]); catch; push!(remove, i); end
    end
    return deleteat!(v, remove)
end

which works well. (I get 819 / 868)

I'll report what happens with teh/subflames

[tlienart]

With teh/subflames I get 1045/1089, better!

Oh wait, you were using a released version of SnoopCompile?

That error looks like it must be due to JuliaLang/julia#38136. I've not updated this to nightly yet. It seems to work on release-1.6, though.

[tlienart]

Ah I should have thought of that, sorry!

The error reported above is with v"1.7.0-DEV.137" ; I just tried with 1.5.3 and there's no error.

Thanks Tim and apologies for the spam!

[timholy]

Not spam. And the current situation may not be clear, so just FYI:

• the teh/subflames branch represents a tip of huge change (estimated 61 commits between the released version and it)
• with that branch, and Julia 1.6, you have access to information that is neither available on any earlier release of Julia or on any earlier release of SnoopCompile
• @snoopi_deep essentially replaces @snoopi, although the latter is kept for compatibility purposes. It's better than @snoopi at parcel/write but it also gives a lot more.

Docs for the new version can be viewed from preview in #192.
