Fails on Mac, and Linux CentOS

[mouse07410]

MacOS Catalina 10.15.5, Xcode-11.5, GHC-8.8.3, Cabal-3.2.0.0 (ghcup-installed), clean ~/.cabal/ directory - has only config files. First thing done - installed all of the cabal-extras, then tried cabal-store-check --repair - with disastrous consequences:

$ type cabal-store-check
cabal-store-check is /Users/ur20980/.cabal/bin/cabal-store-check

I haven't ever tested cabal-store-check on Mac, so it can do something wrong there.

That's why --repair is not a default action, you have to check first that cabal-store-check identifies proper problems.

I haven't ever tested cabal-store-check on Mac, so it can do something wrong there.

Understood. Though what could be different about Mac...?

That's why --repair is not a default action, you have to check first that cabal-store-check identifies proper problems

Understood.

Speaking of other problems: on a different machine (where I did not do cabal-store-check --repair ;-) cabal-diff-test-colour gives me this:

On one Mac machine (where it failed the first time): I re-created ~/.cabal/ from scratch again, re-installed cabal-extras with INSTALL_FLAGS=--disable-shared --disable-executable-dynamic.

Besides ignoring the install flags, it somehow considers ~/.cabal/lib/ as an executable?!

I guess, if one could teach this tool to treat ~/.cabal/lib/ nicer - it could be a useful tool on Mac.

Update 2

It seems that your tools not only expect presence of certain files, but do not tolerate at all when those files are absent. Example: ~/.cabal/store/roots. Neither my Mac nor my Linux Haskell installations have that file. Its absence causes cabal-store-gc to crash:

22 exeopenat(AT_FDCWD, "/home/ur20980/.ghc/x86_64-linux-8.8.3/environments/default", O_RDONLY|O_NOCTTY|O_NONBLOCK) = 15

@phadej do you know what part of code is responsible for determining whether an object with "execute" permissions is a file or a directory? And where that determination result could get lost/ignored?

It's most unpleasant when cabal-store-check interprets ~/.cabal/lib/ as an executable instead of a directory with permissions "readable" and "searchable"...

[mouse07410]

@phadej any chance you can fix this for Mac, with me running tests for you?

[phadej]

The ~/.cabal/store/roots issue should be easy to fix, but that's not the original issue. I don't know why cabal-store-check decided to remove /Users/ur20980/.cabal/store/ghc-8.8.3/lib, such directory shouldn't exist in the first place. So I suspect that your setup was broken beyond repair.

If it works now when you create $HOME/.cabal/store/root manually, then please do it before I'll have time to write a patch (to ignore those roots, when directory doesn't exist).

[mouse07410]

I don't know why cabal-store-check decided to remove /Users/ur20980/.cabal/store/ghc-8.8.3/lib,

Which is why I'm asking you to look into this, as I assume it's your code?

such directory shouldn't exist in the first place.

It should when the system is configured to do dynamic builds. Here's what's stored in that directory:

. . . . . [and so on]

As you can see, that's where Cabal places the shared libraries it builds.

A specific example to the point:

$ exa ~/.cabal/store/ghc-8.10.1/lns-4.19.2-c7b26c58/lib/
Control  GHC       libHSlns-4.19.2-c7b26c58.a  Paths_lens.dyn_hi  System
Data     Language  Numeric                     Paths_lens.hi      
$ exa ~/.cabal/store/ghc-8.10.1/lib/*lns-4.19.2-c7b26c58*
/Users/ur20980/.cabal/store/ghc-8.10.1/lib/libHSlns-4.19.2-c7b26c58-ghc8.10.1.dylib
$ 

So I suspect that your setup was broken beyond repair.

My setup seems to work reasonably fine until something like Agda or other similar build (often using v1- commands) breaks it. So, if something is broken, I tend to lean towards cabal-store-check that seems unable to distinguish between an executable file and a directory.

I'm pretty sure that /Users/ur20980/.cabal/store/ghc-9.0.1/lib/ directory is legitimately created by Cabal to accommodate dynamic builds. it contains shared libraries of packages Cabal installed from Hackage.

Again, can you help, please? Making cabal-store-check work correctly would be a huge improvement.
