Description

In our gnomobile project, we import some Gno packages.
When we try to compile the project with gomobile (a tool that compiles Go code to Android/iOS devices), we have an error in the dependency graph. I think gomobile is more strict to raise errors because I can compile with go build. Anyway, gomobile point out a fatal error:

gobind/gobind imports
       github.com/gnolang/gnomobile/framework imports
       github.com/gnolang/gno/tm2/pkg/crypto/keys imports
       github.com/gnolang/gno/tm2/pkg/crypto/hd imports
       github.com/btcsuite/btcd/btcec tested by
       github.com/btcsuite/btcd/btcec.test imports
       github.com/btcsuite/btcd/chaincfg/chainhash: ambiguous import: found package github.com/btcsuite/btcd/chaincfg/chainhash in multiple modules:
       github.com/btcsuite/btcd v0.22.0-beta.0.20220111032746-97732e52810c (/home/rems14/go/pkg/mod/github.com/btcsuite/btcd@v0.22.0-beta.0.20220111032746-97732e52810c/chaincfg/chainhash)
       github.com/btcsuite/btcd/chaincfg/chainhash v1.0.0 (/home/rems14/go/pkg/mod/github.com/btcsuite/btcd/chaincfg/chainhash@v1.0.0)

This error tells us that the package chainhash is imported in two different ways:

  1. directly in a subdirectory of github.com/btcsuite/btcd v0.22.0-beta.0.20220111032746-97732e52810c. This is now deprecated.
  2. by its path since chainhash has its own go.mod: github.com/btcsuite/btcd/chaincfg/chainhash

I tried to use a new version of github.com/btcsuite/btcd to solve the problem, but the API changed and gno/tm2/pkg/crypto/secp256k1 uses the old API. It's not a hard work to solve, but it's more complex than the other solution and I need to fix this issue quickly to go forward.

So I tried the opposite: to remove the call of the new path github.com/btcsuite/btcd/chaincfg/chainhash. Gno doesn't call it directly, it's a dependency: github.com/btcsuite/btcd/btcutil v1.1.1. The dependency graph (go mod graph) shows me that btcutil v1.0.0 is also call by github.com/btcsuite/btcd v0.22.0-beta.0.20220111032746-97732e52810c, so I tried to downgrade btcutil v1.1.1 to btcutil v1.0.0 and it works! I removed the ambiguous import by keeping the import from btcd v0.22.0-beta.

I'll open a PR to propose my quick fix.

In the future, it should be great to upgrade the btcd dependencies, where some subdirectories become new packages:

  • github.com/btcsuite/btcd/btcec/v2
  • github.com/btcsuite/btcd/chaincfg/chainhash

This would be more robust but it also involves dependency changes in other repos and requires more work. So for now, we can move our project forward with the quick fix PR mentioned above.

I'd avoid downgrading dependencies if possible.

I looked up information about this on the btcd repo. I found this: btcsuite/btcd#1839 (comment)

Can we try applying this diff and see if it works?

It's because github.com/btcsuite/btcutil doesn't import github.com/btcsuite/btcd/chaincfg/chainhash so that don't resolve the issue. This is its dependency graph in Gno:

github.com/btcsuite/btcutil@v1.0.2 github.com/aead/siphash@v1.0.1
