dub Build fails with gdc 13.x

System information

dub version: 1.30 & master
OS Platform and distribution: Linux (Debian)
compiler version gdc 12.2.0

Bug Description

When trying to compile dub using GDC, the build fails while the previous 1.29 version built fine. Error message:

Command `["gdmd", "-of/tmp/dub/bin/dub", "-I/tmp/dub/source", "-version=DubUseCurl", "-version=DubApplication", "-g", "-O", "-w", "@build-files.txt"]` failed, output was:

How to reproduce?

Try to build dub using gdc

Expected Behavior

Either the build succeeds as it did before, or dub emits a message that the compiler/version is unsupported for building dub.

https://github.com/dlang/dub/pull/2548 for WIP changes, but was needing a GDC update.

Your error message looks like the match there doesn't use const properly.

If there was a (even temporary) fix available soonish, we could still get dub 1.30 into the next Debian release. Otherwise this will need a freeze exception, and even though it's a low popularity package, it technically also is a toolchain package which means it's not guaranteed to get that exception (switching to LDC would mean loosing architecture support, which comes with its own administrative issues).

It fails here with the same error, using gdc (Debian 12.2.0-14) 12.2.0 - did the .1 patch release change anything maybe?

You need to build with -Werror to see the message.

Indeed! Removing the -w compile flag "fixes" this error.

on alpine with GDC 12.2.1 the build seems to "work", but gets a linker error at the end:

Ah! I was building dub using the build.d script - after removing -w, it builds and links fine.

Feb 01 '23 21:02 ximion

ah I got the invocation from dub build --compiler=gdc -v

Feb 01 '23 21:02 WebFreak001

Weird that linking fails on Alpine, but Alpine also is a quite different environment compared to traditional GNU/Linux... At Debian we prefer using the build.d script so we don't have a recursive dependency on the older version of dub and bootstrapping is easier (also, dub is a pain to use in packaging, but it's getting better! Which is why 1.30 would be neat to have in Debian 12)

Well, I have to correct myself saying that this works on Debian... Dub itself links fine, but dub compiling another program then fails:

That's not good at all - I'll see if missing references can be boiled down to something palatable, but no guarantees on time.

Will try reducing that dub -Werror in the meantime.

Feb 06 '23 18:02 ibuclaw

It's a bit sad that we'll miss the Debian freeze deadline - I can ask for an exception, but I doubt I'll get it for a new upstream release (so Debian will be stuck at dub 1.28 ...).

In any case, once this works again I'll submit a PR for the dub CI, so we can catch these issues sooner next time :-)

Feb 06 '23 18:02 ximion

you can usually workaround these issues with -fall-instantiations, but it's not ideal.

@WebFreak001 looks like it might be related to that -Wdeprecated -Werrors behaviour you noticed.

Not close to an actual reduction, but this is as far as the mechanical one has taken it.

Package getPackage(PackageOverride ovr)
{
    ovr.match!(
        (any) {
            ovr.version_;
    });
    return null;
}

struct PackageOverride {
    deprecated  inout(Dependency) version_ () inout {
        return Dependency();
    }
}

Feb 06 '23 22:02 ibuclaw

that remaining linker error definitely looks like the bug link Iain just posted (it was the initial linker error that broke the alpine build at the start iirc)

So this remaining linker error you have has actually been known for a few months since I restarted the alpine GDC PR and was fixed by Iain, but still takes some time to sync up with the GCC release cycle.

Feb 06 '23 22:02 WebFreak001

but still takes some time to sync up with the GCC release cycle.

Doesn't prevent Debian/Ubuntu from backporting early.

Feb 06 '23 23:02 ibuclaw

@WebFreak001 looks like it might be related to that -Wdeprecated -Werrors behaviour you noticed.

Yep, building dub with dmd -w -de @build-files.txt gives us the same error message about no handlers.

Feb 06 '23 23:02 ibuclaw

Reduction for the original build failure - not actually a compiler bug, rather a small discrepancy between what warnings-as-errors means between dmd and gdc. There is no distinction between deprecation and warning in gdc diagnostics, so -w turns on deprecations-as-errors too (dmd -de).

template match(alias handler)
{
    auto match()
    {   
        static assert(is(typeof((Override args) => handler(args))),
                      "I do not like green eggs and ham.");
    }
}

void getPackage(Override ovr)
{   
    match!((any) => ovr.version_);
}

struct Override
{
    deprecated int version_ () { return 0; }   
}

Likely dub should be fixed to not use a deprecated interface in the code that makes use of SumTypes.

Confirmed. With PR108055 applied, this whittles down to:

With PR108055 and DFLAGS=-fall-instantiations this compiles successfully however.

Likely being bitten by the template emission changes in the front-end. Will have to adjust for 12.x to get the least surprising behaviour, maybe rethink strategy before 13.x.

Feb 07 '23 01:02 ibuclaw

Likely dub should be fixed to not use a deprecated interface in the code that makes use of SumTypes.

Looks like a simple fix, can you raise a PR or provide a link ?

Feb 07 '23 14:02 Geod24

@Geod24 it comes from this function.

Feb 09 '23 09:02 ibuclaw

Looks like a DMD bug as it doesn't trigger a deprecation when it should.

how much memory does your build machine have? It looks like it was rather OOM killed instead of this being an LDC problem.
