Cannot run on i386 Ubuntu. Fails file locking #6602

newhoggy · 2020-03-22T00:45:00Z

Describe the bug
Running cabal v2-update fails on i386-ubuntu-18.04 running in docker. It's possible that this is unrelated to docker although I've not tested this.

To Reproduce
Steps to reproduce the behavior:

$ docker pull quay.io/haskell_works/ghc-8.8.3:i386-ubuntu-18.04
$ docker run -ti quay.io/haskell_works/ghc-8.8.3:i386-ubuntu-18.04 bash
root@0bbe37ede319:/# cabal v2-update
Config file path source is default config file.
Config file /root/.cabal/config not found.
Writing default configuration to /root/.cabal/config
fdLock: invalid argument (Invalid argument)

Expected behavior
cabal v2-update should work on i386-ubuntu.

System information
Operating system: i386-ubuntu in docker (possible also not in docker)

$ cabal --version
cabal-install version 3.0.1.0
compiled using version 3.0.2.0 of the Cabal library

$ ghc --version
The Glorious Glasgow Haskell Compilation System, version 8.8.2

Additional context

$ strace cabal v2-update

Currently, this is blocking me from setting up CI builds for https://github.com/erikd/wide-word/ on 32-bit Linux.

newhoggy · 2020-03-22T00:48:03Z

Perhaps we shouldn't be using fcntl64 on 32-bit systems and need to fallback to fcntl?

This is interesting:

fcntl64(11, F_OFD_SETLKW, {l_type=F_WRLCK, l_whence=SEEK_SET, l_start=0, l_len=-599317077899083776}) = -1 EINVAL (Invalid argument)

Everywhere fcntl64 fails, l_len is set to a ridiculous number.

phadej · 2020-03-22T00:55:06Z

Please, could you buffer your investigation and post them at once. The mail noise is bad.

newhoggy · 2020-03-22T01:01:50Z

On 64-bit Linux, cabal doesn't even invoke fcntl64, but also the arguments it passes onto fcntl are sensible.

$ cat stderr | grep '\(F_OFD_SETLK\|AT_FDCWD\)' | grep -A 3 /root/.cabal/packages/hackage.haskell.org/hackage-security-lock
openat(AT_FDCWD, "/root/.cabal/packages/hackage.haskell.org/hackage-security-lock", O_RDWR|O_CREAT, 0666) = 11
fcntl(11, F_OFD_SETLKW, {l_type=F_WRLCK, l_whence=SEEK_SET, l_start=0, l_len=0}) = 0
fcntl(11, F_OFD_SETLK, {l_type=F_UNLCK, l_whence=SEEK_SET, l_start=0, l_len=0}) = 0

phadej · 2020-03-22T01:04:45Z

The relevant file is https://github.com/phadej/lukko/blob/master/src-ofd/Lukko/OFD.hsc#L147-L179

I don't see how l_len can turn into something non-zero. Looks like i386 stuff didn't set the field when calling to fcntl64.

newhoggy · 2020-03-22T03:44:14Z

Been trying to build hackage-security on i386, but have been failing with cabal so I'm resorting to stack.

When using stack I saw this:

$ /root/.local/bin/stack build hackage-security
...
[36 of 43] Compiling Hackage.Security.Trusted
/usr/bin/ld.gold: fatal error: .stack-work/dist/i386-linux/Cabal-2.4.0.1/build/Hackage/Security/Trusted.o: Value too large for defined data type

    Process exited with code: ExitFailure 1

Why would the linker fail like that?

This is the stack.yaml I used:

phadej · 2020-03-23T11:07:06Z

The issue is tracked in haskellari/lukko#15

One solution is to compile lukko -ofd-locking. I'm resisting adding configure script to to lukko, but I guess I should do that :( looks like OFD locking wasn't that popular that bugs were fixed more universally.

newhoggy · 2020-03-23T12:46:52Z

I've confirmed the above work around works for me.

newhoggy · 2020-03-29T09:05:15Z

Even though there is a workaround, I think perhaps this issue should be re-opened because it remains the case that the version of cabal available for download has this problem and it would be good to have a new release with this fixed so I can undo all the patches I've made in my CI environment.

simonmichael · 2020-06-24T18:43:02Z

This happened to me today (installed cabal-3.2.0.0 from hackage using cabal-3.0.0.0). I'm trying to work around it like so, and failing:

$ cabal install -w ghc-8.8.3 cabal-install --constraint 'lukko -ofd-locking'
Resolving dependencies...
Build profile: -w ghc-8.8.3 -O1
In order, the following will be built (use -v for more details):

The exception was:

simonmichael · 2020-06-24T19:12:03Z

I was using the faulty cabal-install to rebuild lukko. An older one worked:

$ cabal-3.0.0.0 install -w ghc88 cabal-install --constraint 'lukko -ofd-locking'
$ cabal update  # success

So, worked around, but it wasn't pleasant, and I too think this issue is important.
