Is convert broken?

[davidssmith]

This may be a dup, but so many things are broken for me right now that I need to post about it for either help or catharsis. Why is convert dying on everything? Is this because of the new syntax changes?

I'm frustrated because I have a production code that is now broken, and I can't figure out why. I don't think I changed anything.

For example,

julia> Pkg.add("PyPlot")
ERROR: `convert` has no method matching convert(::Type{UTF8String}, ::ASCIIString)

Can you try

git checkout v0.3.1

And then make. There should not be breaking changes on the release-0.3 branch but maybe something slipped in.

I don't see this. Is this a Yosemite issue? I haven't updated yet, but it might require a recompile of something.

[davidssmith]

I am on Yosemite. I've nuked everything and am recompiling v0.3.1. I'll report back the results.

Was Pkg.add("PyPlot") the first expression evaluated in your Julia session? Asking because convert has been reported to break after using Color (or any package that requires Color), and that hasn't been resolved, so if you didn't use anything that uses Color, a minimal reproducible case that causes the error would be very helpful.

[davidssmith]

Yes it was.

Edit: Wait, what if Color.jl had been pre-compiled in userimg.jl?

[ivarne]

userimg.jl is definitely crucial information. There are lots of issues that packages might cause when they are included there. If this is somehow connected to Color.jl, we should track things connected to that, and there is already an issue (#8631) tracking this, so I'll close this as a dup.

@davidssmith You should usually create a new comment rather than editing a comment when you totally change the content. Lots of people follow discussion on email, and some might have seen the first version, and they don't get to see the edited comment.

[davidssmith]

Thanks for the tip, @ivarne. I did not realize that.

Sounds like userimg.jl is still playing with fire at this stage.

[davidssmith]

For reference, removing Color.jl from userimg.jl seems to have fixed the problem.
