    Handle the duplicate fileid exception thrown at CheckUniqueFileid in tow cases:

    • when duplicate wallets are set on the command line - catch in LoadWallets;
    • when a duplicate wallet is loaded dynamically - catch in LoadWallet.

    Fixes #16776.

    Thanks @promag for working on this.

    Note: the PR description should be updated to suggest reviewing with git show -w 8b8964e

    Functional test wallet_multiwallet.py --usecli is failing for me with AssertionError: [node 0] Expected message "BerkeleyBatch: Can't open database w8_copy \(duplicates fileid \w+ from w8\)" does not partially match stderr: ""

    Here are the results at 8b8964e of loading 2 identical wallets in ~/.bitcoin/testnet3/wallets/ named t7 and t8:

    Dynamically loading a duplicate wallet doesn’t result in the same problem.

    That’s not the case, unfortunately. Tested on Linux Mint 19.2:

    I don’t know if that’s a thing here but there is no function at the end which returns something (In practice it is). Probably some compilers will give a warning or errer so you might should add a return false; at the end @emilengler I think you mean in LoadWallets, note that all branches have a return value.

  15. promag commented at 3:47 pm on January 9, 2020: member
    @hebasto IIRC I tried with no success to hit that, prolly I’ve done something wrong.

    @promag

    @hebasto IIRC I tried with no success to hit that, prolly I’ve done something wrong.

    I can confirm that the fix does not work, unfortunately.

    Steps to reproduce:

    1. prepare a copy of a wallet:
    0$ ls ~/.bitcoin/testnet3/wallets/ | grep w20191015
1w20191015
2w20191015 (copy)
    1. load wallets one by one

    on master:

    0$ ./src/qt/bitcoin-qt -testnet
1terminate called after throwing an instance of 'std::runtime_error'
2  what():  BerkeleyBatch: Can't open database wallet.dat (duplicates fileid f78d2600020800008513f6218301020000000000 from wallet.dat)
3Aborted (core dumped)

    with this pr:

    0$ ./src/qt/bitcoin-qt -testnet
1terminate called after throwing an instance of 'std::runtime_error'
2  what():  BerkeleyBatch: Can't open database wallet.dat (duplicates fileid f78d2600020800008513f6218301020000000000 from wallet.dat)
3Aborted (core dumped)

    Literally, I did steps as described in #16776 (comment)

    i.e., the exception is handled, but the client keeps trying to load the duplicated wallet forever.

    Forever how?

    Run test again: it lasts 2 minutes and keeps going…

    @hebasto I fail to reproduce your case on osx. Does the progress go away when you press “OK” on the “Open wallet failed” dialog? On osx the error dialog shows on top.

    No.

    On osx the error dialog shows on top.

    In a follow-up, it might be helpful if the error message stated the conflicting wallet names.

    But It says :) yeah display the wallet name, not the underlying filename which is useless for directory based wallets.
