[Question] Can't manage to get wasm configured - panic: Could not lock exclusive.lock

[Roc8Trppn]

Hi,

Im using a clone of the interchain-security repo (https://github.com/cosmos/interchain-security) and try to incorporate the CosmWasm module.

Ive done the following:

1. installed the package:
   go get go get github.com/CosmWasm/[email protected]

2. Imported the packages into app.go:

package app

import (
...
wasm "github.com/CosmWasm/wasmd/x/wasm"
wasmkeeper "github.com/CosmWasm/wasmd/x/wasm/keeper"
wasmtypes "github.com/CosmWasm/wasmd/x/wasm/types"
...
)

3. Imported the module into the BasicManager

ModuleBasics = module.NewBasicManager(
  	...
  	wasm.AppModuleBasic{},
  )

4. Defined the keeper in App struct:

type App struct {
	... ,
        WasmKeeper wasmkeeper.Keeper
}

5. In the New method I added the Store Key:

keys := storetypes.NewKVStoreKeys(
		...,
		wasmtypes.StoreKey,
	)

6. And in the same method a bit below created the keeper

        homeDir, dirErr := os.UserHomeDir()
	if dirErr != nil {
		panic(fmt.Sprintf("failed to get user home directory: %v", dirErr))
	}
	wasmDir := filepath.Join(homeDir, "tmp")
	nodeConfig, confErr := wasm.ReadNodeConfig(appOpts)
	if confErr != nil {
		panic(fmt.Sprintf("error while reading wasm config: %s", confErr))
	}
	app.WasmKeeper = wasmkeeper.NewKeeper(
		appCodec,
		runtime.NewKVStoreService(keys[wasmtypes.StoreKey]),
		app.AccountKeeper,
		app.BankKeeper,
		nil,
		nil,
		nil,
		app.IBCKeeper.ChannelKeeper,
		app.IBCKeeper.PortKeeper,
		nil,
		app.TransferKeeper,
		app.MsgServiceRouter(),
		app.GRPCQueryRouter(),
		wasmDir,
		nodeConfig,
		wasmtypes.VMConfig{},
		wasmkeeper.BuiltInCapabilities(),
		"authority",
) 

7. Then I included the module in the NewManager method:

   app.MM = module.NewManager(
   	...
   	wasm.NewAppModule(appCodec, &app.WasmKeeper, nil, app.AccountKeeper, app.BankKeeper, app.MsgServiceRouter(), app.GetSubspace(wasmtypes.ModuleName)),
   )

8. And finally I included the ModuleName into:

app.MM.SetOrderInitGenesis(
		...
		wasmtypes.ModuleName,
	)

When I then try to run the chain I always get the same error:

panic: Could not lock exclusive.lock. Is a different VM running in the same directory already?

goroutine 1 [running]:
github.com/CosmWasm/wasmd/x/wasm/keeper.NewKeeper({_, _}, {_, _}, {_, _}, {_, _}, {0x0, 0x0}, ...)
        /Users/name/go/pkg/mod/github.com/!cosm!wasm/[email protected]/x/wasm/keeper/keeper_cgo.go:86 +0x1012
github.com/cosmos/interchain-security/v5/app/consumer.New({0x1130cd950, 0xc001b7cb60}, {0x11317fa00, 0xc0018cc048}, {0x0, 0x0}, 0x1, {0x113086620, 0xc0015fb6c0}, {0xc00191c460, ...})
...

Ive created a completely new directory where I am sure that no other VM is running but still I keep getting the same error...

Am I missing something in the configuration?

I am not too familiar with integrating wasmd or the interchain-security repo, but the error you are getting results from this check.
The file is located in the wasm specific subfolder of the node's home directory. For example for wasmd that is ~/.wasmd/wasm/wasm/exclusive.lock. The check is to ensure that no two nodes with CosmWasm are running at the same time, trying to read and write modules to the folder.
Maybe try deleting the file?
