cabal new-install allows linking against multiple versions of the same package when internal libraries are used

[vmchale]

Due to the vector package upgrade, the following happened:

cabal: Failed to build ats-pkg-3.2.4.4 (which is required by exe:atspkg from
ats-pkg-3.2.4.4). See the build log above for details.

I believe that this is due to the fact that quaalude (an internal prelude for ats-pkg) depends on dhall. As the build report above attests, quaalude was not rebuilt in light of the vector upgrade; I'm guessing that cabal tried to link the old cached quaalude against the new dhall.

[23Skidoo]

Would it be possible to come up with a small repro case?

[Mikolaj]

I had something similar caused by executable depending on an internal library from its package and the whole (anonymous) library of this package as well (the internal library depended on the whole library as well). In the result, the build used two versions of the whole library (I suppose, it took the whole library already installed previously and then probably compiled the internal library again). Note the double LambdaHack-0.9.2.0 I got in the resulting GHC invocation below. And then the types didn't agree (diamond import problem).

If there is interest, I can create a branch to repro, but I doubt I could come up with a small example.

[23Skidoo]

A repro case would surely be nice to have.

[Mikolaj]

I'm not sure if the errors I'm getting are because I've broken my cabal DB and I don't want to rebuild all the packages to check, but I guess these are the steps to reproduce:

git clone git@github.com:LambdaHack/LambdaHack.git
git checkout 16e5632a10b116905e499f2dd83ca21d0a0be261
cabal new-install -j1 .

If it still doesn't fail, run make build-binary-common.

Edit: yes, after the first cabal new-install I'm getting:

[grayjay]

I wasn't able to reproduce the multiple versions error with LambdaHack. I tried running the first set of commands in #5782 (comment) with both cabal-install-2.4.1.0 and HEAD (27cf519 and 6316102), with GHC 8.6.4 and --index-state=2019-04-01T00:00:00Z.

Cabal listed five LambdaHack components to be built (main library, three internal libraries, and an executable), which seems correct:

In order, the following will be built (use -v for more details):

 - LambdaHack-0.9.2.0 (lib:this-game-src) (requires build)
 - LambdaHack-0.9.2.0 (exe:LambdaHack) (requires build)

Here is the end of the log, which corresponds to the log in the previous comment. I noticed that the components were built in a different order, with this-game-content built between the main library and this-game-src.

There was one directory for each LambdaHack component in the store afterwards.

Which version of cabal caused the error? Were any other packages installed? Do you know what index state was used or have a full log?

[Mikolaj]

@grayjay: thank you for trying to repro. That was cabal version 3.0.0.0, somewhat older than my bug report. I can't tell the exact date. All deps were already installed. Can you try re-installing? I've just tried again with cabal from 6316102 and here's the full log: https://gist.github.com/Mikolaj/5661f4e69635e5c4f3c040ef211b1d68. Note how "indirectly depends on multiple" only appears when I run cabal again. Let me know if I can help any more.

[grayjay]

@Mikolaj Thanks for the log. I tried installing the dependencies separately, as well as making code changes to trigger a partial rebuild, but all of the commands succeeded.

I noticed that the first new-install in the log failed with some profiling errors:

Could not find module ‘Game.LambdaHack.Core.Prelude’
Perhaps you haven't installed the profiling libraries for package ‘LambdaHack-0.9.2.0’?

How is profiling enabled? I tried installing LambdaHack with --enable-profiling, but that failed due to #5982.

[Mikolaj]

Profiling is enabled through my ~/.cabal/config file: https://gist.github.com/Mikolaj/da6494a16d6f121eefad1930394de699

[Mikolaj]

I do remember meddling with cabal package DB before originally posting about the error. Some ghc-pkg invocations, perhaps even some raw deletions from .cabal or .ghc. So now I've removed both .cabal or .ghc and started in a fresh clone of the repo. Compilation succeeded. Then I turned on profiling in ~/.cabal/config (no other changes) and tried again. It recompiled everything and now I'm getting "indirectly depends on multiple versions" again.

[Mikolaj]

I'm now even getting this:

[ 18 of 111] Compiling Game.LambdaHack.Common.Perception ( engine-src/Game/LambdaHack/Common/Perception.hs, dist/build/Game/LambdaHack/Common/Perception.o )

engine-src/Game/LambdaHack/Common/Perception.hs:43:23: error:
    • No instance for (Binary (ES.EnumSet Point))
        arising from the 'deriving' clause of a data type declaration
      Possible fix:
        use a standalone 'deriving instance' declaration,
          so you can specify the instance context yourself
      There are instances for similar types:
        instance (Enum k, Binary k) =>
                 Binary (enummapset-0.6.0.1:Data.EnumSet.EnumSet k)
          -- Defined in ‘Game.LambdaHack.Core.Prelude’
    • When deriving the instance for (Binary PerVisible)
   |
43 |   deriving (Show, Eq, Binary)
   |                       ^^^^^^

which looks like some file corruption to me.

[phadej]

@Mikolaj I don't see any Binary EnumSet instance in https://hackage.haskell.org/package/enummapset-0.6.0.1/docs/Data-EnumSet.html, so that error feels valid?

[Mikolaj]

Well, yes, the instance is here:

https://github.com/LambdaHack/LambdaHack/blob/16e5632a10b116905e499f2dd83ca21d0a0be261/definition-src/Game/LambdaHack/Core/Prelude.hs#L85

but the anonymous library depends on the definition library

https://github.com/LambdaHack/LambdaHack/blob/16e5632a10b116905e499f2dd83ca21d0a0be261/LambdaHack.cabal#L330

so it should be included.

Edit: Which is why it compiles fine most of the time.

[phadej]

Oh, I see.

    • No instance for (Binary (ES.EnumSet Point))

yet

      There are instances for similar types:
        instance (Enum k, Binary k) =>
                 Binary (enummapset-0.6.0.1:Data.EnumSet.EnumSet k)

if it's reproducible, at least on your machine. Could you upload here the plan.json (found in dist-newstyle/cache/plan.json)

[Mikolaj]

@phadej, @grayjay: Yes, it's reproducible, but only once. Then, on a second run (even after cabal new-clean; cabal clean, it exhibits the Could not find module ‘Game.LambdaHack.Core.Prelude’ error instead. So then you have to wipe out ~/.cabal again, do cabal new-update and do

git clone git@github.com:LambdaHack/LambdaHack.git
cd LambdaHack/
git checkout 16e5632a10b116905e499f2dd83ca21d0a0be261
cabal new-install -j1 .

it will succeed. Then set library-profiling: True in ~/.cabal/config, do cabal new-install -j1 . and wait until it all rebuilds. Only then you get the error (if you enable profiling in the first run, I think, it just succeeds, but the evidence has scrolled pass the terminal memory threshold, so I'm not sure). The resulting plan.json after the error is

Configuring library for LambdaHack-0.9.2.0..
Warning: The package has an extraneous version range for a dependency on an
internal library: LambdaHack -any && ==0.9.2.0, LambdaHack -any && ==0.9.2.0,
LambdaHack -any && ==0.9.2.0. This version range includes the current package
but isn't needed as the current package's library will always be used.
Warning:
    This package indirectly depends on multiple versions of the same package. This is very likely to cause a compile failure.
