ldc: 1.17.0 -> 1.20.1 #85488

lionello · 2020-04-18T10:15:03Z

Motivation for this change

Current ldc uses an extremely old version of ldc 0.x to bootstrap the latest ldc 1.x, causing more and more issues as the gap between the two versions widens.

Things done

Using precompiled binaries from GitHub of vLatest-1 to bootstrap latest version. This is similar to the work done in dmd: 2.085.1 -> 2.091.1 #82694 .

Thanks a lot for this!

Was there a specific reason why the previous version is used for bootstrapping?
I can think of no technical reason but it would make it even easier if the same version is used for bootstrapping.
This way only one version specifier needs to exist.

I am not sure if it is good to provide the bootstrap package this way.
It should not be available to the outside because it is not a "nice" package but a hackish one and is only needed for building the real package which provides the same functionality.
I can only imagine a testing scenario where having the bootstrap package available that way but this is highly speculative as I don't have a concrete example.
Even if such an example could be found it's for sure quite rare and can be added by a developer temporarily without polluting the namespace.

I agree, ldcBootstrap is an implementation detail that shouldn't be exposed.

Could advertise it as ldc_bin or ldc.bootstrap, probably.

In any case, it should be exposed in some way, otherwise how one can override it.

@veprbl What do you mean?

It could simply be done by calling binary.nix directly from generic.nix like it was done in the previous solution [1].
This way bootstrap.nix and ldcBootstrap in all-packages.nix would not be necessary any more.

[1] https://github.com/NixOS/nixpkgs/blob/19.09/pkgs/development/compilers/ldc/default.nix#L13

@ThomasMader If I need to override bootstrap ldc in an overlay, how do I do that?

@veprbl I see, @lionello already solved it by using callPackage as the default parameter like this -> ldcBootstrap ? callPackage ./bootstrap.nix { }

Yes, this looks better. It would also help if the original bootstrap value was exposed. e.g. add passthru = { inherit ldcBootstrap; }.

@ThomasMader Feel free to ping me for merge on this PR and the dmd one.
(though I'm not sure because I see "WIP")

lionello · 2020-04-19T07:55:42Z

@worldofpeace It's WIP because I'm getting a failure during check phase on my local MacBook. Need to dig in.

ThomasMader · 2020-04-19T08:45:44Z

@lionello What failure? Can you elaborate? Mostly I can't help without digging in too but maybe we are lucky.

lionello · 2020-04-19T13:03:21Z

@ThomasMader Actually, it's dmd that still has a failure on macOS: #82694 (comment)

@worldofpeace @ThomasMader Locally, this now builds successfully on macOS and NixOS with tests passing.

@worldofpeace would it be possible to get this into 20.03 or is the release already frozen?

We've been go for the final release for a week https://discourse.nixos.org/t/go-no-go-meeting-nixos-20-03-markhor/, so we're very past the freeze.

I issued the build command @ThomasMader because I didn't see it build on macos for you. So I guess that means you aren't in "trusted users" in ofborg, which basically means you can build on darwin plus other minor stuff.

ThomasMader · 2020-04-20T13:17:27Z

I used to be able to build on Darwin too. Never mind.

Oh, did we need to merge dmd together?

ThomasMader · 2020-04-22T04:24:22Z

Yes merging #82694 should fix those problems.
Nobody knew in advance, the version difference was just too big.
