cabal haddock --executables fails with "internal error when calculating transitive package dependencies" #1919

massysett · 2014-06-04T00:01:23Z

When running

cabal haddock --executables

the command fails with

cabal: internal error when calculating transitive package dependencies.
Debug info: []

I have tagged my source code tree where this problem exists:

https://github.com/massysett/penny/tree/cabal_error

This is cabal-install version 1.20.0.2.

Seeing this error on one of my projects as well.

creichert · 2014-12-15T05:58:42Z

I can confirm this error as well with the --executable flag.

creichert · 2014-12-18T20:34:49Z

I've tracked this error down to the dependencyClosure function.

cabal/cabal-install/Distribution/Client/PackageIndex.hs

Line 346 in 5c70361

dependencyClosure :: PackageFixedDeps pkg

From the local documentation:

Note that if the result is @right []@ it is because at least one of the original given
'PackageIdentifier's do not occur in the index.

It seems to be a problem resolving the inplace package dependency of the local library. When I remove that dependency I am able to generate the haddocks for the executable.

Would anyone familiar with the cabal code be able to give me anymore pointers for digging into this more? I don't mind spending more time to fix this.

taladar · 2015-03-29T20:23:26Z

Has any progress been made on this issue? We have some projects with significant code in the modules which only appear in the executable and it would be great if documentation could be generated for those as well. Of course removing the dependency on the local library is not really an option.

edsko · 2016-06-20T02:06:56Z

This problem still occurs with 1.24.0.0.

alexbiehl · 2018-10-27T00:46:23Z

I think this is fixed with latest Cabal. Christopher Lewis <[email protected]> schrieb am Sa., 27. Okt. 2018, 06:54:

FWIW, this bug still exists for the v1-haddock command in cabal-install 2.4.1.0. It occurs when an executable depends on the library defined in the current package.

mietek · 2019-02-14T16:11:51Z

My cabal-fail-one repository is now named cabal-issue-1919.

int-e · 2019-02-14T16:30:58Z

Note that new-haddock is affected by a different issue that also causes executable documentation to not be built in some cases (including @mietek's repository, I think): #5890.

madgen · 2019-10-17T13:20:28Z

I get the same error when I use cabal haddock on a package with internal libraries with Cabal 2.4.1.0. Since Stack currently supports up to Cabal 2.4, I imagine this affects some number of people.

Is the only workaround to just not use internal libraries? Does anyone have an idea where to start poking to work towards a patch?

Due to a bug about haddock, cabal, and intenal libraries (haskell/cabal#1919), `haddock` fails, so remove it from CI for now.

hsenag · 2020-08-23T16:40:28Z

FYI I'm getting this on darcs 2.16.2:

Seems like this is still an issue? I'm surprised this issue is still open after 7 years. Is there any progress yet? Is this work blocked by another issue, or can it be worked on today?

Mikolaj · 2021-06-04T20:36:58Z

I don't see any label suggesting this is blocked (e.g., on a haddock bug), so I guess any work on this would be very welcome.

I'm surprised this is still failing: I'm running haddock on projects with multiple libraries and it works for me (even if it's rather useless until this haddock work is streamlined: haskell/haddock#1379). Apparently the pattern of internal library deps matters.

Mikolaj · 2021-06-04T21:25:48Z

It works for me with development version of cabal (I run cabal haddock. Which version and what commandline do you use?

brandon-leapyear · 2021-06-04T21:51:20Z

✨ This is an old work account. Please reference @brandonchinn178 for all future communication ✨

oh interesting. It fails with stack haddock. With debugging enabled, I see it failing when running

.../.stack/setup-exe-cache/x86_64-osx/Cabal-simple_mPHDZzAJ_3.2.1.0_ghc-8.10.4 --builddir=.stack-work/dist/x86_64-osx/Cabal-3.2.1.0 haddock --html --hoogle --html-location=../$pkg-$version/ --haddock-option=--hyperlinked-source --haddock-option=--quickjump

so maybe it's a GHC bug?

EDIT: never mind, this is the cabal executable built by stack

Mikolaj · 2021-06-05T00:24:46Z

Could you make stack build a newer cabal executable? Preferably dev version from branch master? This one looks like 3.2 and it works fine with 3.5 for me and the invocation you show does not see particularly wild, so perhaps this was fixed already?

Hm so I checked out the Cabal-v3.4.0.0 tag to build 3.4, and then running cabal haddock worked. But then using Cabal 3.4 with Stack still fails

$ /Users/bchinn/.stack/setup-exe-cache/x86_64-osx/Cabal-simple_mPHDZzAJ_3.4.0.0_ghc-9.0.1 --builddir=.stack-work/dist/x86_64-osx/Cabal-3.4.0.0 haddock

So it's probably a Stack bug.

I believe this issue can be closed. Mostly because cabal haddock --executables seems to not be a thing anymore

Mikolaj · 2021-06-05T08:42:58Z

It would still be nice to report on Stack issue tracker and perhaps improve Cabal to avoid this problem, if it's more on our side.

brandon-leapyear · 2021-06-05T19:26:26Z

✨ This is an old work account. Please reference @brandonchinn178 for all future communication ✨

It is tracked for Stack: commercialhaskell/stack#4428

But it actually might be a bug in GHC/Cabal, now that I'm digging further. Can you clone my minimal repro again (https://github.com/brandonchinn178/stack-repro-4428) and do the following:

ghc-9.0.1 -package Cabal-3.4.0.0 Setup.hs -o setup
./setup configure
./setup haddock

Ok I think I have a better idea of what's going on.

It seems that when calling cabal haddock, the haddock function (from Distribution.Simple.Haddock) is called separately for each component (in the minimal repro, the foo library, and the foo-internal internal library), so when building the haddocks for foo-internal, the foo library is registered.

But when manually building Setup.hs and calling haddock via Cabal-the-library, the haddock function is called once for everything, so when building the haddocks for foo-internal, the foo library doesn't exist.

Technical details

cabal haddock

haddock is called first with LocalBuildInfo containing:

configFlags.configArgs = ["lib:foo"]
componentEnabledSpec = OneComponentRequestedSpec (CLibName LMainLibName)
installedPkgs.unitIdIndex containing:

base-4.14.1.0
ghc-prim-0.6.1
integer-gmp-1.0.3.0
rts

Then haddock is called with LocalBuildInfo containing:

configFlags.configArgs = ["lib:foo-internal"]
componentEnabledSpec = OneComponentRequestedSpec (CLibName (LSubLibName (UnqualComponentName "foo-internal")))
installedPkgs.unitIdIndex containing:

base-4.14.1.0
foo-0.1.0.0-inplace
ghc-prim-0.6.1
integer-gmp-1.0.3.0
rts

Setup.hs, Cabal-the-library

haddock is called once with LocalBuildInfo containing:

configFlag.configArgs = []
componentEnabledSpec = ComponentRequestedSpec {testsRequested = False, benchmarksRequested = False}
installedPkgs.unitIdIndex containing:

base-4.14.1.0
ghc-prim-0.6.1
integer-gmp-1.0.3.0
rts

Mikolaj · 2021-06-07T09:07:09Z

Reproduced. Got setup: internal error when calculating transitive package dependencies. What does ./setup configure even do?

So it looks like cabal problem? The Setup way outdated vs the v2 way?
