    If the user has unchecked “Allow incoming connections” in Settings->Options...->Network then fListen=false is saved in ~/.config/Bitcoin/Bitcoin-Qt.conf. This flips -listen to false during startup, but leaves -listenonion to true.

    This flipping of -listen is done in OptionsModel::Init() after InitParameterInteraction() has been executed which would have flipped -listenonion, should it have seen -listen being false (this is a difference between bitcoind and bitcoin-qt).

    Fixes: https://github.com/bitcoin-core/gui/issues/567

  2. options: flip listenonion to false if not listening 
    If the user has unchecked "Allow incoming connections" in
`Settings->Options...->Network` then `fListen=false` is saved in
`~/.config/Bitcoin/Bitcoin-Qt.conf`. This flips `-listen` to `false`
during startup, but leaves `-listenonion` to `true`.

This flipping of `-listen` is done in `OptionsModel::Init()` after
`InitParameterInteraction()` has been executed which would have flipped
`-listenonion`, should it have seen `-listen` being `false`
(this is a difference between `bitcoind` and `bitcoin-qt`).

    Another approach would be to execute OptionsModel::Init() (which translates GUI options from ~/.config/Bitcoin/Bitcoin-Qt.conf to the “normal” config settings) before InitParameterInteraction(). That would be bigger and more intrusive change.

    Concept ACK

    • This fix addresses the issue and seems to correct it without removing a previously added feature.
    • As far as I understood the problem, the issue was because the setting of -listen to 0 depended on fListen, while the setting of -listenonion to 0 depending on -listen. And both of these variables were being set at different times during the startup, leading to incorrect values for them.
    • This PR fixes the problem by adding the code to set listenonion to 0 if fListen is false, consequently preventing the bug due to setting the value of listen and listenonion at different times in the startup.

    Let me test if this PR fixes the bug in question.

    Tested 7f90dc26c8938f348938929b6d8bf1ea6f149209 on Ubuntu 22.04, the bitcoin-core/gui#567 has been fixed.
  12. hebasto commented at 11:57 am on March 23, 2022: member
    FWIW, bitcoin/bitcoin#15936 also fixes #567. And in long term I do prefer @ryanofsky’s PR.

    It fixes the issue and bitcoin-qt starts without any error when incoming connections are disabled.

    Concept ACK on disabling Tor listening when listening is disabled, this would be the least surprise. I don’t know enough about the forest of interacting options and Qt initialization to know if this is the clearest solution, but I think it will work.

    In commit “options: flip listenonion to false if not listening” (7f90dc26c8938f348938929b6d8bf1ea6f149209)

    Would be good to add a comment here explaining this like “Handle interaction between -listen and -listenonion settings. This duplicates logic in InitParameterInteraction(), but is required because InitParameterInteraction() has already run before this point and will not be called again. Longer term fix will move these settings to settings.json, so normal parameter interaction will apply.”

    vasild commented at 4:24 pm on March 23, 2022:
    Right! I will look into adding the unit test and add a comment here as a followup.

    Code review ACK 7f90dc26c8938f348938929b6d8bf1ea6f149209.

    Nice simple fix! Agree fixing this in the GUI is better than changing bitcoind behavior to enable listening.

    I think it might be possible to write a simple unit test for this bug in https://github.com/bitcoin/bitcoin/blob/master/src/qt/test/optiontests.cpp by setting the bad listen value, initializing the options model, and then calling AppInitParameterInteraction to trigger the “Cannot set -listen=0 together with -listenonion=1” error. I think it would be good to add the unit test because it seems to me that https://github.com/bitcoin/bitcoin/pull/15936 only partially fixes this bug and could cause a regression after this PR.

    Tested ACK 7f90dc26c8938f348938929b6d8bf1ea6f149209 I verified locally that the problem occurs and is fixed by this patch. Also tried to find if any other parameter interactions might be affected by the same kind of problem, but couldn’t spot any.

    @hebasto I went out after testing this pull request, don’t know how to check this and nothing can be confirmed with make or make install however I trust you and other reviewers in this pull request so I agree with the changes.

    Yeah, a package list in the guide is a bit outdated. Use https://github.com/bitcoin/bitcoin/blob/master/doc/build-unix.md directly.
