Give feedback during slow function calls

[tfiers]

Try e.g. in a fresh session, using PkgGraph; depgraph_image(:Plots). is slow.

so ig, figure out uncompiled methods. some kinda flag, or a julia internal we can abuse

[tfiers]

Actually subsequent runs are also kinda slow, for this big (and non-installed) package (compare with eg :ChainRulesCore).

so yes, some kinda progress indication here. as predicted in

• Crawl registry (→ to rm restriction "Only works for pkgs in active project") #5 (comment)

mayb if gathering deps (repeatedly calling that init_pkg_info!) is slow, then a line for each or sth

[tfiers]

Ooh actually, SnoopPre :)

Re

• Add precompilation #97 (comment)

hah, so it wasn't a precomp issue

so it's more like "Give feedback during slow function calls"

step 1:

• profile

oh god, profview on WSL..

ok, according to this [https://learn.microsoft.com/en-us/windows/wsl/tutorials/gui-apps], should be possible
so, downloading 1GB "Intel® Graphics – Windows* DCH Drivers", gfx_win_101.3790_101.2114.exe

oh wow, gedit example works out of the box, not even having installed that intel gpu driver

ok and profview works out of the box too.
so I'm scared of that driver: could make it not work anymore

To run Linux GUI apps, you should first install the driver matching your system below. This will enable you to use a virtual GPU (vGPU) so you can benefit from hardware accelerated OpenGL rendering.

Do I have vGPU / hardware-accelerated OpenGL rendering already?

https://www.hanselman.com/blog/how-to-run-linux-gui-apps-on-windows-10-with-wsl-and-wslg
https://ubuntu.com/tutorials/enabling-gpu-acceleration-on-ubuntu-on-wsl2-with-the-nvidia-cuda-platform#1-overview

ok, two trusted sources, seems legit

someone w/ same question: microsoft/wslg#78
glxinfo is part of that Mesa
https://en.wikipedia.org/wiki/Mesa_(computer_graphics)

an open source implementation of OpenGL, Vulkan, and other graphics API specifications. Mesa translates these specifications to vendor-specific graphics hardware drivers

The intel installer failed (I chose "clean install (remove old drivers & reset settings to default)"; but it said sth "file not found" halfwya tru)

[tfiers]

ok, so can't optimize that really.
So, feedback there, sure :)

only in direct_deps_from_registry (double clicked it; opened in code. woah. <3 ProfileView)

[tfiers]

We don't know how deep the rabbit hole goes (how many pkgs in tree) beforehand.
So, cannot use the nice ProgressMeter.jl

I want the cool spinners of Pkg etc

oh no, ProgressMeter has them: https://github.com/timholy/ProgressMeter.jl#progress-meters-for-tasks-with-an-unknown-number-of-steps

[tfiers]

So ok, we have this now (see upcoming commit closing this).
though there is about 4 secs delay before it shows up:

• Add precompilation #97 (comment)

..and ProgressMeter.jl has no precompilation, alas.
