Adding Revise to `startup.jl` breaks Pkg mode

[liamh]

If Revise is added to startup.jl

using Revise

then Pkg mode no longer shows any output for anything. It will resume working if Pkg is imported

(In this demonstration, the entire contents of the startup.jl file is simply using Revise.

What's your platform and Julia version? How did you install Julia? There is something broken on your system.

I've run into the same issue:

Julia installed via juliaup, was working fine before and I'm not sure what could have changed

[serenity4]

Does anything change if you start Julia with -e 'using REPL'?

[rossviljoen]

julia -i -e "using REPL" still has the same issue, although julia -i -e "import Pkg" works fine

[serenity4]

Ok, thanks. It still looks very much like a require_stdlib issue to me, where import Pkg loading the PkgREPLExt extension solves it. Does it look the same to you @timholy? (unfortunately these are hard to reproduce...)

By any chance, do you have Pkg explicitly installed in your (global) environment (and, possibly, with a custom/deved path)?

No, I didn't have Pkg explicitly installed, and this even happens with nothing else in the global env:

Do you have something like the following?

Ah, there it is, we have a duplicated REPL entry (short story: both versions of REPL are loaded, one as an "internal" stdlib, and one as a "standard" package).

I managed to reproduce the issue with a fresh depot:

$ JULIA_DEPOT_PATH=/tmp/julia-depot julia +1.11 -e 'using Pkg; Pkg.add("Revise")'
$ mkdir -p /tmp/julia-depot/config
$ echo "using Revise" >> /tmp/julia-depot/config/startup.jl
$ JULIA_DEPOT_PATH=/tmp/julia-depot julia +1.11

The bug does not appear in 1.12+ (the REPLExt extension loads after pressing ]st, then Pkg commands work fine), which has a workaround with JuliaLang/julia#58415, marked for backport to 1.11.8 in JuliaLang/julia#59521.

I don't know of an immediate temporary workaround, other than trying to reinstall Julia either with juliaup or manually, unfortunately.

Looks like JuliaLang/julia#58415 isn't able to be automatically backported to 1.11.x, so someone will need to make the backport manually.

[DilumAluthge]

I can confirm that I am able to reproduce this with Julia 1.11.7, Revise v3.9.0, a fresh Julia depot, and a config/startup.jl file that only contains using Revise.

If I remove using Revise from the startup.jl file, then the bug goes away.

[liamh]

The workaround I have used with 1.11.4 for the last several months is to import Pkg in startup.jl

using Revise
import Pkg # Necessary or Pkg mode will not show output

Can someone who has permission reopen this issue please?

[DilumAluthge]

Looks like JuliaLang/julia#58415 isn't able to be automatically backported to 1.11.x, so someone will need to make the backport manually.

A huge thank you to Jameson for manually backporting JuliaLang/julia#58415 to the Julia 1.11.8 backports branch; the backport commit is JuliaLang/julia@bef4090.

So the fix should be included in 1.11.8 when it is released.
