Initial shot at using Gtk on Julia 1.3+

[staticfloat]

Note that this requires the Julia 1.3+ version of cairo as well (which is why the Project.toml shows Cairo.jl as being dev'ed)

This doesn't work totally yet; it crashes halfway through the tests on my mac because it can't load some icons.

This now passes all tests locally, but the windows that pop up are never drawn into; they remain white. More debugging information below.

[tknopp]

For reference here is a list of TODO items:

• Make it work on Windows, Travis could be enabled
• Make it work on Linux
• We get on Mac this warning: gdk-pixdump possibly not installed correctly JuliaPackaging/Homebrew.jl#121 (comment). If I recall we did not have this with the working homebrew setup. From that link one can crawl the history since maybe @staticfloat has resolved this at that time
• Package loading went from 2s to 12s. This is not really acceptable given that the linux setup currently runs fine.
• Fix the warning: (julia:4891): Gtk-WARNING **: 21:55:48.913: infinite surface size not supported

Shouldn't the separator be a semicolon on Windows? @ianshmean can you please check if this fixes the issue you reported yesterday? As far as I can see, this variable is not currently set on Windows, so I'm not sure this will be sufficient...

On my linux desktop, using Gtk on this branch takes 15s, which is abysmal.

We know that at least 30% of this is due to a regression in type inference, at least 10% of it is due to missing precompile statements in Pkg, and there is a suspiciously large amount of code being generated within the JLL precompilation files. We're looking into it, but these issues almost certainly will not be fixed in 1.3, but will have to be addressed with a 1.3.1 release.

Windows seems to be failing to create the gdk-pixbuf cache. I'm investigating.

Just on AppVeyor, right? On Travis CI its is working on windows. The only thing is that one warning we see on all platforms.

[staticfloat]

That's correct; I'm guessing there's some kind of DLL missing in the cut-down Travis environment or something, because in my test on a full windows workstation, it works just fine. I'm not going to look into it anymore then. :)

[tknopp]

If Travis runs reliably, there is no need for appVeyor.

In my all-platforms build Travis timed out on Windows (but cannot see why on the phone): https://travis-ci.com/giordano/Gtk.jl/builds/133476408

[staticfloat]

It looks like the while sleep 540 ; do echo "===== saying hello to Travis ====="; done loop keeps running in the background forever.

[giordano]

That was to keep Travis awake in the aarch64 build 😩

[staticfloat]

I think you're going to need to do a little bit of job control on windows; after the main script has ended, you'll need to kill your background task. This is probably only a problem on windows.

I'm trying this on windows 10 (julia v1.3 and Cairo master) but I'm getting this :

Is it supposed to work ? Maybe I should try with a clean install.

[giordano]

WARNING: redefining constant libgdk
WARNING: redefining constant libgtk

doesn't sound right I think. Do you still have something in deps/?

Maybe I should try with a clean install.

That would make sure that you're not messing up with some leftover of previous installations

[tknopp]

Current travis run looks ok despite x86 on windows.

[tknopp]

@jonathanBieler: The JLL branch had an issue with existing deps/* files which were in the gitignore. Try switch to master where I have fixed this and make sure that there is no deps directory anymore.
