New minecraft version. (1.15)

[xoft]

If you were an op / admin, and suddenly blocks started disappearing around you, I think you'd start caring
True, this is quite far-fetched. We'll see.

It's almost time for 1.7: https://mojang.com/2013/10/minecraft-1-7...the-world/

I've just glanced through the 1.7 protocol, I have to say I'm pleasantly surprised. FINALLY they decided to include a length field for each packet, so that it can be easily parsed

[NiLSPACE]

1.7.2 is released.

[xoft]

I guess I'll have to more-than-glance at the protocol docs

[xoft]

I seem unable to run the vanilla 1.7.2 server. I start the exe, the java process starts and then terminates within a second, without showing any window or even spitting anything in the console. Does this happen to anyone else?

Ah, found it - not enough RAM. When run with less RAM in the -Xmx and -Xms params, the server started just fine.

---

It wouldn't be Mojang if there weren't a stupid twist in the protocol.

The packet type 0 is used for 0 different things, based on whether one has been already received or not - initial handshake or keepalive. WHY?

---

Also, they renumbered the packets, just so that the numbers are different now. No logical reason behind the renumbering, the packets aren't grouped any better than before.

---

And the packets have different numbers in each direction? WTF are they smoking there? Why is a chat packet type 1 in one direction, but type 2 in the other?

[FakeTruth]

Yup, sounds like something Mojang did
You know something's wrong when their protocol starts making sense

[mtilden]

Networking is completely re-written, so... good luck!

[xoft]

It is doable, we just lost a bit of in-source documentation - we had comments like "sends an UpdateWindowProperty (0x69) packet", which are now mostly invalid.

The server issue persists, it seems I've hit this one:
https://mojang.atlassian.net/browse/MC-33014

When I specify the -Xms1024M param, the server crashes with the error; if I use 512M instead, it starts fine. I have enough free phys & virt RAM to run 1024M.
