I’m pleased to announce the 1.0 release of SnoopCompile , a package that can be used to diagnose and sometimes reduce package startup latencies (a.k.a., “time to first plot”). Version 1.0 brings a couple of new features: the ability to “automate” precompile-file generation via @snoopi. This makes @…

Does SnoopCompile filter out methods that depend on gensymmed names that might not be valid in other versions / builds of julia? In that case, is there any way to keep them,in case you are making your own sysimage for example ? (One of the major contributions to the improved startup in Julia 1.0 was…

@snoopi returns everything; it’s just SnoopCompile.parcel that’s implements filtering. As you can see , for @snoopi the implementation of parcel is almost trivial, so we could easily tweak it if you think there are gains to be had.

What’s the support for keyword argument functions like? Using @snoopi created some statements like: precompile(Tuple{PaddedMatrices.var"#mul_tn_quote##kw",NamedTuple{(:negative, :force_inline),Tuple{Bool,Bool}},typeof(PaddedMatrices.mul_tn_quote),Int64,Symbol,Int64,Type,Bool,Symbol,Symbol,Int64}) …

Anything that breaks across Julia versions is a bug, so please report it (with reproducer) as an issue in SnoopCompile. Obviously generated functions don’t help, since both the generated function and the function that is generated need to get compiled. If you have essentially limitless type comb…

[image] tim.holy: Anything that breaks across Julia versions is a bug, so please report it (with reproducer) as an issue in SnoopCompile. Does that include Julia-master? I just verified a case where @snoopi created on master (and working there) errors on 1.3. ERROR: LoadError: UndefVarError…

SnoopCompile 1.1 is out. It fixes a lot of the reported problems and adds a whole lot of additional robustness. In particular, this version looks up keyword methods in a manner that doesn’t depend on gensymmed names, particularly if you do the snooping on Julia 1.4+. (The precompile.jl file it write…

Absolutely. The precompile files need to work robustly across versions.
