* Add option to not send pre v25 init packetest312016-03-15
| | | | | | | | | | | | | | | | | The legacy init packet (pre v25) sends information about the client's password that a server could use to log in to other servers if the username and password are the same. All the other benefits of SRP of protocol v25 are missed if the legacy init packet is still sent during connection creation. This patch adds an option to not send the v25 init packet. Not sending the v25 packet means breaking compat with pre v25 servers, but as the option is not enabled by default, no servers are affected unless the user explicitly flips the switch. More than 90% of the servers on the serverlist support post v25 protocols. The patch also fixes a bug with greying out of non compliant servers being done wrongly, the min and max params were mixed.

* Nodebox: Allow nodeboxes to "connect"Auke Kok2016-03-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We introduce a new nodebox type "connected", and allow these nodes to have optional nodeboxes that connect it to other connecting nodeboxes. This is all done at scenedraw time in the client. The client will inspect the surrounding nodes and if they are to be connected to, it will draw the appropriate connecting nodeboxes to make those connections. In the node_box definition, we have to specify separate nodeboxes for each valid connection. This allows us to make nodes that connect only horizontally (the common case) by providing optional nodeboxes for +x, -x, +z, -z directions. Or this allows us to make wires that can connect up and down, by providing nodeboxes that connect it up and down (+y, -y) as well. The optional nodeboxes can be arrays. They are named "connect_top, "connect_bottom", "connect_front", "connect_left", "connect_back" and "connect_right". Here, "front" means the south facing side of the node that has facedir = 0. Additionally, a "fixed" nodebox list present will always be drawn, so one can make a central post, for instance. This "fixed" nodebox can be omitted, or it can be an array of nodeboxes. Collision boxes are also updated in exactly the same fashion, which allows you to walk over the upper extremities of the individual node boxes, or stand really close to them. You can also walk up node noxes that are small in height, all as expected, and unlike the NDT_FENCELIKE nodes. I've posted a screenshot demonstrating the flexibility at http://i.imgur.com/zaJq8jo.png In the screenshot, all connecting nodes are of this new subtype. Transparent textures render incorrectly, Which I don't think is related to this text, as other nodeboxes also have issues with this. A protocol bump is performed in order to be able to send older clients a nodeblock that is usable for them. In order to avoid abuse of users we send older clients a "full-size" node, so that it's impossible for them to try and walk through a fence or wall that's created in this fashion. This was tested with a pre-bump client connected against a server running the new protocol. These nodes connect to other nodes, and you can select which ones those are by specifying node names (or group names) in the connects_to string array: connects_to = { "group:fence", "default:wood" } By default, nodes do not connect to anything, allowing you to create nodes that always have to be paired in order to connect. lua_api.txt is updated to reflect the extension to the node_box API. Example lua code needed to generate these nodes can be found here: https://gist.github.com/sofar/b381c8c192c8e53e6062

* Backface culling: Ignore setting in tiledef from old servers.Auke Kok2016-01-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | Outdated servers are always sending tiledefs with culling enabled no matter what, as the value was previously entirely ignored. To compensate, we must (1) detect that we're running against an old server with a new client, and (2) disable culling for mesh, plantlike, firelike and liquid draw types no matter what the server is telling us. In order to achieve this, we need to bump the protocol version since we cannot rely on the tiledef version, and test for it being older. I've bumped the protocol version, although that should have likely happened in the actual change that introduced the new backface_culling PR #3578. Fortunately that's only 2 commits back at this point. We also explicitly test for the drawtype to assure we are not changing the culling value for other nodes, where it should remain enabled. This was tested against various pub servers, including 0.4.13 and 0.4.12. Fixes #3598

* Add server side ncurses terminalest312015-11-06
| | | | | | | | | | | | | | | | | | | | | | | | This adds a chat console the server owner can use for administration or to talk with players. It runs in its own thread, which makes the user interface immune to the server's lag, behaving just like a client, except timeout. As it uses the same console code as the f10 console, things like nick completion or a scroll buffer basically come for free. The terminal itself is written in a general way so that adding a client version later on is just about implementing an interface. Fatal errors are printed after the console exists and the ncurses terminal buffer gets cleaned up with endwin(), so that the error still remains visible. The server owner can chose their username their entered text will have in chat and where players can send PMs to. Once the username is secured with a password to prevent anybody to take over the server, the owner can execute admin tasks over the console. This change includes a contribution by @kahrl who has improved ncurses library detection.

* Serialisation: documentation fixes, clarifying renames and whitespace fixesest312015-09-14
| | | | | | | | | | | | | | | 1. Do two renames: * SER_FMT_CLIENT_VER_LOWEST -> SER_FMT_VER_LOWEST_WRITE * SER_FMT_VER_LOWEST -> SER_FMT_VER_LOWEST_READ Now the two define values are consistently named with the _WRITE defines SER_FMT_VER_{HIGHEST,LOWEST}_WRITE, and to better point out what the two serialisation versions actually are for. 2. wrap some lines in doc/worldformat.txt, and point out that the node timers are serialized at a later point, as this can cause confusion about what now happens (if one doesn't strictly read the if block's conditions). 3. some whitespace fixes in NodeTimerList::serialize, and one new comment.
* networkprotocol.h: remove "u16 command" from docest312015-09-10
| | | | | | | Its obvious that "u16 command" is inside every packet, therefore this commit removes all mentions of the command, if non-array like notation is used. We already didn't add "u16 command" to new packets or removed it at packet changes, so now we remove it from existing packets.

| | | | | | | This was needed due to the TileDef serialisation changes. Originally it has been planned to also add utf-8 based chat to 26, but chat changes aren't final yet, so they are done in one change, after the release, and not two small ones, causing us having to be compliant to three versions of the packet.
