I found a way to confuse stack and require a manual removal of the local package database, or something to that effect. I haven't worked out all the details, but basically what I've done is this:

  • Initialize a new project and add persistent and persistent-template as dependencies (using lts-3.4, this brings in persistent-2.2 and persistent-template-2.1.3.4:
-- snapshot db
/Users/mrosen/.stack/snapshots/x86_64-osx/lts-3.4/7.10.2/pkgdb
   persistent-2.2 (persistent-2.2-7814fec4f4ee40ea6b1f627410f1c9eb)
   persistent-template-2.1.3.4 (persistent-template-2.1.3.4-4508b858709b85b5c0149527551ed9fc)
  • Decide that I want to modify persistent locally and build against it, so I git clone it and add /path/to/local/persistent to my stack.yaml's packages
  • Rebuild, which causes persistent-template to rebuild and depend on this local persistent.
-- local db
/Users/mrosen/junk/.stack-work/install/x86_64-osx/lts-3.4/7.10.2/pkgdb
   persistent-2.2 (persistent-2.2-3dd9b8c4bcaf5265acba55fc4993f288)
   persistent-template-2.1.3.4 (persistent-template-2.1.3.4-4508b858709b85b5c0149527551ed9fc)
  • Decide that I want to go back to building against the snapshot's persistent, so I delete the line from stack.yaml
  • Get this error:
Warning: This package indirectly depends on multiple versions of the same
package. This is highly likely to cause a compile failure.
package persistent-template-2.1.3.4 requires persistent-2.2
package junk-0.1.0.0 requires persistent-2.2
junk-0.1.0.0: build
Preprocessing library junk-0.1.0.0...
<command line>: cannot satisfy -package-id persistent-template-2.1.3.4-4508b858709b85b5c0149527551ed9fc:
    persistent-template-2.1.3.4-4508b858709b85b5c0149527551ed9fc is unusable due to missing or recursive dependencies:
      persistent-2.2-3dd9b8c4bcaf5265acba55fc4993f288
    (use -v for more information)

I think I'm getting this error because junk is unregistered before rebuilding, but my local persistent-template and persistent are not. Thus, junk goes to depend on the snapshot persistent-2.2-7814fec4f4ee40ea6b1f627410f1c9eb, while my local persistent-template still depends on the local persistent-2.2-3dd9b8c4bcaf5265acba55fc4993f288.

I haven't figured out how to get out of this situation without rm -rfing the local package db and rebuilding.

Deleting local packages from stack.yaml and expecting stack to work 100% correctly might be asking too much. I know stack doesn't attempt to be any sort of package manager, nor support any cleaning up of build artifacts. Still, I don't feel I did anything too out the ordinary with temporarily shadowing a snapshot package with a local one. If anything, a stack clean && stack build should have "just worked", but stack clean doesn't appear to do anything :)

I confirm the bug
I had the same problem a few days ago.
I didn't find any other way but to rm -rf the local package db too

I've been tracking down a number of bugs all around a similar concept here, but unfortunately haven't been able to reproduce any of them (this included). Can you provide the --verbose output, and confirm that this reproduces on the latest master?

Sure. I can reproduce it with HEAD @ c0525a2.

I was able to reproduce this finally with some help. Here's the problem: the installed package ID is not unique, and the exact same one is being used in both the snapshot and local databases. This means that when we say "I want persistent-template-deadbeef", it's completely ambiguous whether we mean the one in the snapshot or local database. GHC will choose the one in the later package database (which is the local one), which depends on the local copy of persistent, which we're no longer building against.

@mitchellwrosen your comment about unregistering seems like the right resolution here, though I'd prefer if there was a way to tell GHC much more directly which installed package we want. The problem here is that GHC can distinguish between two installed copies, but there's seemingly nothing we can say on the command line to make that distinction.

I think this is now resolved, can you give it a shot on master?

Yes, sorry I didn't make myself clear in the original post. I meant to point out that it's curious persistent-template had the same hash in both cases. Shouldn't a package's hash depend on its contents, dependencies, and its dependencies' hashes (not just their versions)?

Anyways, that was fast! I'll try a bit later today.

Pleasure, glad it's working! Now just debating whether I should open up a Cabal bug report about the matching installed package ID issue.
