Ability to test long paths...

[DynConcepts]

I have an immediate specific need for long path support on windows. Found

Support core.longpaths on Windows #5347

but it does not appear to have been merged yet.....

It there a build (even if unofficial) that I could use for test purposes???

Can be tested like this:

using (var config = Configuration.BuildFrom(null))
{
    var longpaths = config.GetValueOrDefault<bool>("core.longpaths", ConfigurationLevel.Global);

    // can use also "git config --system core.longpaths true", but requires elevation.
    if (!longpaths)
        longpaths = config.GetValueOrDefault<bool>("core.longpaths", ConfigurationLevel.System);

    _useCoreLongPaths = !longpaths;
}

Also need to test that windows supports long paths:

[SupportedOSPlatform("windows")]
static bool Reconfigure()
{
    using (RegistryKey key = Registry.LocalMachine.OpenSubKey(@"SYSTEM\CurrentControlSet\Control\FileSystem"))
    {
        object o = key.GetValue("LongPathsEnabled");
        if (!(o is int) || (int)o == 0)
        {
            Console.WriteLine("\n\nError: Please enable 'LongPathsEnabled' registry entry accoding to:\n" +
                "https://learn.microsoft.com/en-us/windows/win32/fileio/maximum-file-path-limitation?tabs=registry\n");
            return false;
        }
    }

    return true;
}


...somewhere in Main...

if (RuntimeInformation.IsOSPlatform(OSPlatform.Windows) && !Reconfigure())
{
    return -3;
}

Maybe close this ticket ?

👍 Indeed we support long paths on windows.
