I keep wondering why the time-to-first-whatever is such a difficult problem. It is currently my main issue with Julia by a fair margin (I do know about Revise and PackageCompiler, but also about their limitations). There is clearly something I don’t understand, and would appreciate some insights. I…

Saving a snapshot is pretty much exactly how the sysimg that is shipped with Julia is built. JuliaLang/julia/blob/e39f498aca58abb8aecac34d329d7de9a0cead02/sysimage.mk#L75-L82 $$(build_private_libdir)/sys$1-o.a $$(build_private_libdir)/sys$1-bc.a : $$(build_private_l…

Isn’t that basically what Revise and PackageCompiler already allow for? My understanding is that the same limitations would apply to any approach that saved the compilation state: i.e. you couldn’t redefine types saved in this image (ala Revise) and there may be existing compiler bugs/limitations re…

Well, Revise doesn’t survive reboots and PackageCompiler doesn’t work with a whole workspace (which can have several non-trivially interacting packages loaded), and is tricky to get to work in general, AFAIU. So this is an honest question, I really have the feeling there is some core aspect of Juli…

Oh! So you think it would be possible?

I don’t think that’s the right question. It may not be impossible, but it would surely be a lot of work for a very specific purpose, and making compilation faster would have more general benefits.

Understood, thanks @Tamas_Papp . But my point is, making compilation faster (i.e. faster inference + caching more things) is different from making it instantaneous (i.e. caching all things)… The latter would undoubtedly also have its appeal. In any case: is there any open Github issue (analogous to …

[image] pablosanjose: is there any open Github issue (analogous to the PARTR one) tracking ideas/work towards the goal of faster compilation? Use tags, eg [image] Issues · JuliaLang/julia The Julia Programming Language. Contribute to JuliaLang/julia development by creating an acc…

Actually, there is one that I’m watching that’s not yet a PR to the JuliaLang repo: julia/test/standalone-aot at standalone-mode · tshort/julia · GitHub This branch lets one compile (small, simple) programs to native code as an executable, in an AOT manner like PackageCompiler, but uses an approach…

I had not really succeeded in using PackageCompiler until now, but I now get it! It is indeed a great solution, once you get it to run. I guess if you have no binary deps it is much smoother. I wish I could mark two posts as solutions, Fezzik also looks great.

Save complete session snapshot?
