Deal with compressed registry in Julia v1.7

[giordano]

At the moment we assume the registry is uncompressed on disk. For users in Julia v1.7+ this may not be the case. Pkg.jl in Julia v1.7 comes with an API to deal with the registry in all cases (both compressed and uncompressed) which is probably the best option, that'd mean to drop support for Julia v1.6, but I believe that's reasonable.

Is there a workaround? I always get the following error message:

julia> analyze("DataFrames")
ERROR: ArgumentError: collection must be non-empty
Stacktrace:

As I said above already, the uncompressed registry (e.g. as a git repository) still works. The alternative is for someone to write the code to use the API in Julia v1.7+ to deal with both formats, but I'm not very motivated to do that since locally I still use the uncompressed registry.

But how can I get an uncompressed registry? I did:

cd .julia/registries
tar xzf General.tar.gz

But this did not help.

And why not merging https://github.com/JuliaEcosystem/PkgDeps.jl/pull/39 which should fix this issue?

You'd have to opt-out the PkgServer by setting the environment variable JULIA_PKG_SERVER=""

And why not merging https://github.com/JuliaEcosystem/PkgDeps.jl/pull/39 which should fix this issue?

Because the two packages aren't related in any way?

What version of PackageAnalyzer.jl are you using? There may actually be a simple workaround without messing with Julia's registry

[ufechner7]

(Analyze) pkg> st
      Status `~/repos/Analyze/Project.toml`
  [b19fd437] KiteControllers v0.1.3
  [e713c705] PackageAnalyzer v0.1.0

I tried: JULIA_PKG_SERVER="" before launching Julia.

But I still get the same error: ERROR: ArgumentError: collection must be non-empty
