This will allow us to resolve the Dates at compile-time eventually. It also fixes TOML.Parser() to return Dates types again.

The plan is to land:

  1. This PR
  2. Use Base.TOML.Parser{Dates} for TOML parsing w/ Dates support Pkg.jl#3938
  3. TOML: Improve type-stability #55016

This is a breaking change for anyone who was using the internal Dates support downstream, but then again so was #54755

This allows the `Dates` calls to be statically inferred
This change also adds back the `.Dates` field, which negates the type
stability improvements for now but can be removed once we land a fix to
Pkg to use the new internal constructor.
This is another backwards compatibility concession to Pkg, which we'll
remove in the breaking follow-up PR.

#54755 was only breaking if you accessed internals of TOML, but otherwise should be transparent to the consumer of public APIs

Doesn't the TOML parser no longer return Dates objects by default, unless you use the new DTParser constructor?

I don't think that type was made public, or was the standard way to call into the package

TOML.Parser is public and it should parse dates so we have to fix that.

I see we backported #54755 so presumably we have to backport a fix for that...

return parser
end
# Dates-enabled constructors
Parser() = Parser{Dates}()

Type piracy I guess. Maybe that's ok.

I left a comment behind in base/toml_parser.jl specifically delegating this definition to the TOML stdlib, so I think this is fine.

I see we backported #54755 so presumably we have to backport a fix for that...

I think this change should be backportable for that

No type-stability improvements unless we back-port all three PR's, but the other two are optional to backport

@KristofferC KristofferC removed the backport 1.11 Change should be backported to release-1.11 label Aug 26, 2024
topolarity added a commit that referenced this pull request Sep 7, 2024
Dependent on #55017. This changes
the output of the TOML parser to provide specialized `Vector{T}` less
aggressively.

Specifically, combinatorially expensive types like
`Vector{Vector{Float64}}` or `Vector{Union{Float64,Int64}}` are instead
returned as `Vector{Any}`, while vectors of homogeneous leaf types (e.g.
`Vector{Float64}`) are still supported as before.

This change makes the TOML parser fully type-stable.
