Pkg.jl: Duplicate key `AutoHashEquals`

[DatName]

Recently I started to get following error when updating a project of mine:

Resolving package versions...
ERROR: Pkg.TOML.ParserError(17686, 17700, "duplicate key `AutoHashEquals`")

Really lost here. I noticed that there were some changes in General Registry (https://github.com/JuliaRegistries/General/pull/8953) but can't figure out if it is related or not.

I dont think I changed anything manually in Project/Manifest.toml files.

Could you post your Project + Manifest and the Pkg operation you are trying to do?

Note, that it has some private packages which I can not share.
I am doing up in activated project

[KristofferC]

Let's try this instead.

Start Julia then run

using Pkg

@eval Pkg.TOML begin
           parsefile(filename::AbstractString) =
               (@info "parsing file $filename";  open(parse, filename, "r"))
       end

It should now print all the files it parses and when it errors the file should have been printed just above it.

[DatName]

Wow.
Ok, I see that it points to Deps.toml file in my custom registry. And this file indeed has duplicated entries of AutoHashEquals.
I could not see that in Atom because just hides duplicated line. It is not shown even in search.
But I can clearly see it in another text editor. Nice.

@KristofferC Thank so much for this!

The TOML parser should really print out the file + line number it has problems with instead of just a byte offset.
