varjolintu commented Oct 18, 2018


If keepassxc-proxy binary (default or custom location) is not found after support for some browser is enabled, a warning message will be shown in the Browser Integration settings tab. The path where keepassxc-proxy is loaded will be shown in the message. Hopefully this makes the troubleshooting easier.

The warning message should be as non-tech as possible, but still informative. Any suggestions are very welcome.

And because the class is quite hard to read, I also added some documentation to the functions.

This PR is still under Needs Work label because I haven't tested this with all platforms.

Motivation and context

Adds more information about the native messaging host location during troubleshooting.

How has this been tested?


Screenshots (if appropriate):

Recommended wording:

Warning, the keepassxc-proxy application was not found!
Please check the KeePassXC installation directory or confirm the custom path in advanced options.
Browser integration WILL NOT WORK without the proxy application.
Expected Path: %path%

* @param browser Selected browser
* @return bool Script is installed correctly
bool HostInstaller::checkIfInstalled(SupportedBrowsers browser) const

When you changed this to a const function you fail to build on windows because "registryEntryFound" is not a const function.
