Alex generates code that cannot be compiled by GHC 9.2 #246

Vekhir · 2023-10-18T12:59:44Z

Hi,
the issue occurs with the package hopenpgp-tools (Hackage, source).
The code works fine with GHC 9.0.2, but fails to build with GHC 9.2.8 with the errors below. They concern some changes with IntN# requirements in the type signatures. It looks similar to #187, but occurs on both alex 3.2.7.4 and 3.4.0.0 as released on Hackage.

I also made a report over at hopenpgp-tools: clint/hopenpgp-tools#6

Edit: Solution

Older versions of alex generate code incompatible with GHC 9.2, which is fixed in newer versions. However, packaging issues can prevent alex from regenerating code from incompatible versions. Make sure that the package does not include build artifacts.

System information

OS: Arch Linux
Kernel: Linux 6.5.7-arch1-1
GHC: 9.2.8
hopenpgp: 2.9.8

Quick question @Vekhir, out of curiousity : Is there any reason why you are using 0.23.7 and not the latest release, 0.23.8 of hopenpgp-tools.

Vekhir · 2023-10-18T14:10:27Z

@andreasabel There are three main reasons:

The official Arch package is on 0.23.7 and updating is another variable if something goes wrong
hopenpgp-tools 0.23.8 only introduces support for optparse-applicative 0.18, so the update doesn't fix the issue
0.23.8 requires optparse-applicative >=0.18.1.0 and updating to that would introduce more variables while not fixing the issue (the official Arch package is on 0.17.0.0).

In short, there is nothing to suggest that 0.23.8 fixes this issue, so I stick with the version that the official Arch package uses.

andreasabel · 2023-10-18T14:57:30Z

Thanks for the answer!

I checked building 0.23.7 with GHC 9.2.8 and everything went fine:

$ cabal get hopenpgp-tools-0.23.7

$ cd hopenpgp-tools-0.23.7/

Could it be that you have some HOpenPGP/Tools/Lexer.hs generated by an older version of alex? Probably not.
It is more likely you have a stale alex in your PATH.
What is which alex?

But now I see that you might be using the v1 interface of cabal.

Try using cabal v2-build (which is cabal build with any recent Cabal).

Vekhir · 2023-10-18T15:18:28Z

The package is built in a clean chroot, i.e. in a newly created, isolated environment and according to the instructions in the PKGBUILD.

This means that not cabal build, but runhaskell Setup build is used. Does this make a difference?

Output of which alex:
/usr/bin/alex

andreasabel · 2023-10-18T16:55:58Z

Output of which alex:
/usr/bin/alex

It could well be that this alex is picked up, you can check alex --version whether it is too old.

I suppose runhaskell Setup build also accepts the -v3 verbosity flag, so maybe this will print the PATH it uses etc and which alex is used.

I have no experience with runhaskell Setup instead of cabal, seems like a thing from the past. Or maybe, if you do not want to install cabal-install, but just Cabal, then you might do so.

andreasabel · 2023-10-18T16:57:12Z

I don't think this is a problem of alex but more one of your setup. So, I am closing this. We can continue the discussion anyway.

Vekhir · 2023-10-18T22:46:51Z

I've collected some more information which might be useful.

Output of alex --version:
Alex version 3.4.0.0, (c) 2003 Chris Dornan and Simon Marlow
Running with -v3 shows that it uses /usr/bin/alex, see below
dist/build/hot/hot-tmp/HOpenPGP/Tools/Lexer.hs
dist/build/hkt/hkt-tmp/HOpenPGP/Tools/Lexer.hs
hopenpgp-tools.cabal for 0.23.7, as available on Hackage.

Interesting result

Interestingly enough, the former "hot" version does contain the #if __GLASGOW_HASKELL__ >= 901 guards, while the "hkt" version does not. Considering that this was one of the tell-tale signs of #187, it seems like the configuration is correct for hot, but somehow different for hkt.

What do you think?

Info

Running with -v3, i.e. runhaskell Setup build -v3 -j17:

[...]

Of note is the line

/usr/bin/alex -g -o dist/build/hot/hot-tmp/HOpenPGP/Tools/Lexer.hs HOpenPGP/Tools/Lexer.x

which only occurs once and is seemingly only run for hot,
and the entry in Environment

("PATH","/usr/local/sbin:/usr/local/bin:/usr/bin:/usr/bin/site_perl:/usr/bin/vendor_perl:/usr/bin/core_perl")

which is repeated several times, but always the same.

I've also extracted the
dist/build/hot/hot-tmp/HOpenPGP/Tools/Lexer.hs
which is mentioned above as the target of the alex command, and the
dist/build/hkt/hkt-tmp/HOpenPGP/Tools/Lexer.hs, which is the Lexer.hs for hkt.

For completeness, here is the hopenpgp-tools.cabal for 0.23.7, as available on Hackage.

runhaskell Setup

runhaskell Setup is a low-level interface, whereas cabal-install provides a high-level interface, which is reflected in the many dependencies it draws upon. The difference starts to matter when considering that cabal build does a lot more than just building a package, not least including its own system for package management.

andreasabel · 2023-10-19T06:43:56Z

I see that Lexer.hs and Parser.hs (dating June 2022) are included in the tarball for 0.23.7:

$ cabal get hopenpgp-tools-0.23.7
Unpacking to hopenpgp-tools-0.23.7/

$ find . -name "Lexer.hs"
./hopenpgp-tools-0.23.7/dist/build/hop/hop-tmp/HOpenPGP/Tools/Lexer.hs
./hopenpgp-tools-0.23.7/dist/build/hot/hot-tmp/HOpenPGP/Tools/Lexer.hs
./hopenpgp-tools-0.23.7/dist/build/hkt/hkt-tmp/HOpenPGP/Tools/Lexer.hs

This may prevent their (re-)generation with alex in install methods like runhaskell Setup build.
This explains the build failure with recent GHCs.

Apparently, their tarball was not created with cabal sdist, because that does not package the generated lexer and parser. So, it could be a packaging error on the side of the hopenpgp-tools.
(I have made a similar error in the past, when publishing https://hackage.haskell.org/package/BNFC-2.8.3.)

andreasabel · 2023-10-19T06:51:12Z

there is nothing to suggest that 0.23.8 fixes this issue,

In fact, I checked the tarball of 0.23.8, and it no longer includes the generated Lexer.hs. So I think it would fix the problem indeed.

@Vekhir : Could you report the progress to https://salsa.debian.org/clint/hopenpgp-tools/-/issues/6 ? I don't have an account there and cannot log in with my github account there.

Vekhir · 2023-10-19T13:09:15Z

Adding a step to first delete the dist/ directory before building did indeed fix the issue.

there is nothing to suggest that 0.23.8 fixes this issue,

In fact, I checked the tarball of 0.23.8, and it no longer includes the generated Lexer.hs. So I think it would fix the problem indeed.

One takeaway for me is to always check out the updates to get the differential, even if it introduces new variables. Though I will take the fix over updating in this case, for now at least.

Could you report the progress to https://salsa.debian.org/clint/hopenpgp-tools/-/issues/6 ?

Done!

Thanks for your help in investigating the issue. Can you close this issue as completed (vs. not planned)?

andreasabel · 2023-10-19T13:18:03Z

@Vekhir: I am happy that I could help you solve this issue!

I suppose "closing as not planned" does include the case that the issue was never on our side (alex) but caused by a third party (here: hopenpgp-tools).

Would you please reopen https://salsa.debian.org/clint/hopenpgp-tools/-/issues/6 ?
I think the maintainer should deprecate the affected versions on hackage, and ideally also make them unbuildable. This can be done by Hackage revisions by the maintainer.

Vekhir · 2023-10-19T13:38:17Z

the maintainer should deprecate the affected versions on hackage

What are the reasons for that? There were no issues with cabal build, and for older versions of GHC (< 9.2) they work as is. The public API of hopenpgp-tools isn't the issue aswell. So this seems quite drastic to me.

andreasabel · 2023-10-19T20:44:20Z

The problem is that the wrong packaging is a mine that people may randomly step on (like it happened for you).
There should be a clear indication of this issue. Deprecation would be a clear marking. (Note that this would still people to install this version if they insist, only it would by default not chosen by cabal in constraint solving.)
And a bound base < 4.16 would indicate that there are (could be) build problems with GHC 9.2 and above.
Of course, I assume here that the older versions are not essential to anyone. Usually folks are fine to use the newest version.
