cabal install/build: static executables and stripping

[prez]

Description
Various combinations of configure/build/install and --enable-executable-static / --enable-executable-stripping do not produce a static + stripped executable.

System information
Alpine Linux - musl libc and busybox.

~/test # cat /etc/alpine-release
3.12.0

~/test # cabal --version
cabal-install version 3.4.0.0
compiled using version 3.4.0.0 of the Cabal library 

~/test # ghc --version
The Glorious Glasgow Haskell Compilation System, version 8.10.3

Setup

~/test # ls
Main.hs     test.cabal

~/test # cat Main.hs 
main :: IO ()
main = putStrLn "Hello, Haskell!"

~/test # cat test.cabal 
cabal-version:       3.4
name:                test
version:             0.0.0

executable tst
  main-is:             Main.hs
  ghc-options:         -O2 -Wall -Wcompat
  default-language:    Haskell2010
  build-depends:       base >=4.14 && <4.15

Steps to reproduce

1. trying cabal install, directly:

cabal install --installdir=. --install-method=copy --enable-executable-stripping --enable-executable-static
observation:

~/test # file tst
tst: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib/ld-musl-x86_64.so.1, with debug_info, not stripped

verbose output:

~/test # cabal install --verbose --installdir=. --install-method=copy  --enable-executable-stripping --enable-executable-static

Oof, that didn't go well at all. Dynamic, not stripped.

2. trying cabal build:

~/test # cabal clean

~/test # cabal build --enable-executable-stripping --enable-executable-static

Still static but not stripped...

So the conclusion is that stripping just doesn't work and static linking is unreliable, at least for me.
This is either a pretty sad state of affairs, or I am missing something very obvious.

Additionally, I also find the interaction between the commands in 2. and 3. and cabal install to be a bit weird, the executable is getting rebuilt even with the same flags set in install when running cabal install even though nothing changed and everything should be cached. But that is another topic.

Expected behavior
Stripped and statically linked executables.
(tst: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), statically linked, stripped)

Additional context
Ghc and cabal were installed via ghcup in a clean environment.

I confirm 1 with newest dev cabal and GHC 9.2.0-alpha. I get the following error with 2 and 3:

which probably is a libc error, fixed 2 months ago after 8 years: https://sourceware.org/bugzilla/show_bug.cgi?id=15648

Generally, I've heard statically linking with libc is hard and produced binaries that are not portable. Which may be why people do this differently: https://github.com/utdemir/ghc-musl and https://github.com/nh2/static-haskell-nix. Which may also be why cabal or GHC silently ignores it sometimes. I agree it should not be silent about it.

So, in this issue, I'd focus on the lack of stripping. I've repeated 1, 2 and 3 without --enable-executable-static and the binary is always not stripped, so it's not an interaction with static mode. I've also repeated install without the other flags and no change.

[Mikolaj]

The following

#2702 (comment)

tells me that cabal build was never supposed to produce stripped binaries. We definitely need more cabal warning when options are ignored for whatever reasons (stripping, static).

However, I tried

cabal install --installdir=. --install-method=copy --enable-executable-stripping --disable-debug-info

and the binary is still not stripped. Moreover I added build-info:3 to ~/.cabal/config and I don't get the warning that the ffd45c5 should produce. That would suggest --enable-executable-stripping is lost even before debug-info kicks in. Possibly yet another silent override. @mpickering: what am I missing? should the invocation above produce a stripped binary? I assume it did in Jun 2019 when you tested your commit?

which probably is a libc error, fixed 2 months ago after 8 years: https://sourceware.org/bugzilla/show_bug.cgi?id=15648
Generally, I've heard statically linking with libc is hard and produced binaries that are not portable. Which may be why people do this differently: https://github.com/utdemir/ghc-musl and https://github.com/nh2/static-haskell-nix.

System information
Alpine Linux - musl libc and busybox.

I am already using musl, not glibc. It is thus clearly a cabal issue.

musl

Oh, I missed that. I hope installing musl and busybox on my old Ubuntu 16.04 won't be a problem, in case I try to repro and debug. Anyway, stripping first, in case it's somehow related.

Here's an easy way to get an alpine container up and running:

sudo apt install lxd
sudo lxd init
lxc launch images:alpine/edge a1
lxc exec a1 ash

hope it helps.

Indeed my old Ubuntu is enough to repro the musl stuff. I've followed these docker instructions exactly and I reproduced all 3 cases from the ticket description with GHC 9.0.1.

Minor related inconsistency: the default ~/.cabal/config says "-- executable-stripping:\n", while it's supposed (doc/installing-packages.rst) to have the default value there, which doc/cabal-project.rst and others claim to be True in this case. And indeed Cabal/src/Distribution/Simple/Setup.hs, which I assume sets the default values, has

configStripExes    = NoFlag,

instead of Flag True that it had before b408d16.

Edit: though there is still

, opt   "stripped-exe" True  prettyShow pkgHashStripExes

in cabal-install/src/Distribution/Client/PackageHash.hs, but also

elabStripExes     = perPkgOptionFlag pkgid False packageConfigStripExes

in cabal-install/src/Distribution/Client/ProjectPlanning.hs.

Edit2: the cleared default seems to be compensated for elsewhere in b408d16.

[Mikolaj]

b408d16 and f5e713d are off the hook, because I reverted their relevant parts and no change in behaviour observed.

[Mikolaj]

OK, as far as I can see, stripping (possibly also static linking) was just never implemented for the new-* commands. At least, the new codepaths, the ones that really get called for new-*, e.g., the one containing installBuiltExe, never attempt to call Strip.stripExe that the old paths called, nor any code that contains it.

Before we set up to implement this, we'd need a consensus about when the stripping should be called: whether only when copying exes for new-install, or already when creating the exe files, which is done in new-build as well (but then it would be stripping in place, I guess?). The documentation would need to reflect that, as well. For static linking, there is no doubts about when to do it, I suppose, and we probably don't want to try and guess if it's going to fail, e.g., due to libc. So that could be attempted without any discussion.

Edit: are there any TODO notes somewhere for functionality waiting to be implement for new-* and how to do it?

Edit2: given that static linking does work for new-build, the hypothesis, by analogy to stripping, is that it's not implemented for new-install only. Porting from new-build to new-install should be easier than from v1-install to new-install. Unless there is a good reason it wasn't implemented for new-install specificaly, but I doubt it. Is there?

Edit3: I'm leaving this for now until I get any feedback.

[Mikolaj]

@typedrat, @fgaz: do you by chance remember what was the original plan for new-install and new-build regarding stripping and static linking? Right now new-build links statically, if requested, but new-install silently ignores the request. Both silently ignore stripping request. I'm not counting on any design doc, but your memory or even just gut feeling would already give us something to work with.

[Mikolaj]

@fgaz: to simplify the question: should both new-build and new-install honour stripping and static linking flags? If yes, why do you think so?

@fendor: I see your contributions there, too, perhaps you would know?

Thank you!

[fgaz]

I'd say yes, especially if v1- did. As for why, install is basically the only way to "deploy" an executable with cabal-install in a way that isn't dependent on the builddir, so it makes sense to be able to strip and link statically with it too

what was the original plan for new-install and new-build regarding stripping and static linking?

I don't think there was a specific plan for new-install except "do what new-build does", and I wasn't yet following cabal's development when new-build planning happened

[Mikolaj]

@fgaz: thank you. In that case, I think the plan to fix this issue, at last re stripping, but possibly also for static linking, can be to port the chunks of v1 code to v2 and otherwise scavenge and transplant until we reach feature parity in this respect between v1, v2, build and install. If nobody volunteers, I may attempt that at some point, given that I've already code-dived a bit.
