    Is there an existing issue for this?

    • I have searched the existing issues

    Current behaviour

    On execution bitcoind fails to start and logs Failed to start error. Have pasted logs into the logs section.

    It looks as though there is some rpc config required for this to run, but have not found a way to specify whats required. When i hard code a username/password in utils.py .. fails with Connection Refused.

    Example Command python functional/feature_rbf.py --loglevel=DEBUG --tracerpc

    Config.ini [environment] PACKAGE_NAME=Bitcoin Core PACKAGE_BUGREPORT=https://github.com/bitcoin/bitcoin/issues SRCDIR=/usr/src/bitcoin BUILDDIR=/usr/src/bitcoin EXEEXT=.exe RPCAUTH=/usr/src/bitcoin/share/rpcauth/rpcauth.py

    Expected behaviour

    The test should run to completion.

    Steps to reproduce

    Build 27.* on Ubuntu WLS

    Execute python test with example command. python functional/feature_rbf.py –loglevel=DEBUG –tracerpc

    Error: Specified data directory “/tmp/bitcoin_func_test_u9zpt_2g/node0” does not exist.

    This seems to be the first error, so it would be good to debug this first. Can you check whether /usr/src/bitcoin/test/cache/node0 exists and whether the following is successful:

    2024-09-04T18:07:10.780000Z TestFramework (DEBUG): Copy cache directory /usr/src/bitcoin/test/cache/node0 to node 0

    Given that you claim that bitcoin.conf exists (presumably in this dir), the error message that the directory does not exist seems odd.

    Generally, it may be a bit difficult to get the Windows functional tests run on Linux, which is probably also the reason why the corresponding CI task only runs the Windows unit tests on Linux: https://github.com/bitcoin/bitcoin/runs/29691284283

  7. maflcko commented at 8:09 am on September 5, 2024: member

    Even if you get it to run, Wine will print errors to stderr, which the functional test framework does not like, so they will have to be silenced one way or another.

    When you say edit the config.ini paths, what would i be editing here please?

    For WSL, can you share exact steps to reproduce, please? I guess they are https://github.com/bitcoin/bitcoin/blob/28.x/doc/build-windows.md ?

    You can try to manually edit the paths in the config ini file to point to the “source dir” and “build dir”. The source dir is the folder that contains the src cpp files (e.g. 'src', 'rpc', 'client.cpp'). The build dir is the folder that cointains the exe files (e.g. bitcoind.exe). They may be identical, depending on your build. Inside WSL this is not needed. However, outside WSL (in Windows) this should be required.

    Used the 27.x branch ..followed the steps based on https://github.com/bitcoin/bitcoin/blob/27.x/doc/build-windows.md except the “make deploy”

    then i just navigate to the path, and invoke the test

    all this is on WSL including the invocation of the test. I don’t leave that env.

  16. maflcko commented at 9:48 am on September 5, 2024: member

    Ok, thanks for confirming.

    I don’t have WSL, so I can’t test this. However running the functional tests inside WSL was never supported, IIRC.

    Even if you work around your initial issue, the test framework and individual tests have to modified for the Wine environment.

    So my recommendation would be to run the tests on Windows directly. However that isn’t possible out-of-the-box either and requires modifying the config ini file.

    Ok, thanks for confirming.

    I don’t have WSL, so I can’t test this. However running the functional tests inside WSL was never supported, IIRC.

    Ok good to know re support for running the tests in WSL.

    Let me have a play getting these to run on windows directly.

    I think it would be fine to add support for functional tests in WSL (or document how to do it), but I am not sure how easy it is.

    I presume adding support for tests directly on Windows is easier (or adding documentation on how to do it). However, I don’t use WSL, nor Windows, so I can’t tell for sure.
