Random nameserver failures at start of program on Windows about dns

[kelunik]

Could you please modify vendor/amphp/windows-registry/lib/WindowsRegistry.php:19 and add a var_dump($key, $lines); there? What does that output?

[Bilge]

Before or after the yield?

---

Edit: I guess it would have to be after, otherwise $lines wouldn't be initialized.

[bwoebi]

Obviously after the yield: before, $lines isn't defined yet.

Worth noting that it picks up the DNS server from my router (212.158.248.5 and 83.146.21.5) but I've overridden them in the IPv4 settings of the network adapter, which I guess it does not pick up. No idea how reliable those ISP servers are normally because I don't use them.

Strange that MaxUserPort REG_DWORD DhcpNameServer REG_SZ 212.158.248.5 83.146.21.5 ends up in a single line.

The notice probably comes from the NameServer key, that exists but is empty.

We could read ...\Tcpip\Linkage\Route for the order of network interfaces. Currently we just traverse the registry in the order the keys are printed out.

Any movement on this? At first I thought it might be rare, but I find it's occurring more than 50% of all program runs, which is starting to become quite a hassle.

Zombie process wrappers are starting to become endemic...

Never mind, I updated my dependencies and it doesn't happen any more, so the bug wasn't even in the DNS library, I guess.
