* Dungeons: Generalise use, add capabilities, various modificationsparamat2016-06-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | - Generalise node names to c_wall and c_alt_wall - Remove 'mossratio' and instead disable alt_wall loop if c_alt_wall == CONTENT_IGNORE - Use one generalised 3D noise for alternative wall nodes and in mgv6 create moss distribution similar to the previous - Rename rarity noise to density noise and enable the option of multiple dungeons per chunk determined by the value. Recreate previous distribution - Add parameters for min and max rooms per dungeon - Add dungeon y limits - Integrate river water properly Generalisation is needed now that we have sandstone and desert stone dungeons by default and can choose any node for alternative structure. The current code is based around cobble dungeons with mossycobble alternative nodes, the 2 noises controlling the alternative nodes are based on wetness. Enabling multiple dungeons per chunk with definable number of rooms allows the option of very dense and complex underground structures that could interconnect to create megastructures. Y limits are added to be consistent with other mapgen elements, and enable locaton of dungeon or megastructure realms as part of our 'stacked realms' philosophy.

* Add minetest.check_password_entry callbackest312016-05-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | Gives a convenient way to check a player's password. This entirely bypasses the SRP protocol, so should be used with great care. This function is not intended to be used in-game, but solely by external protocols, where no authentication of the minetest engine is provided, and also only for protocols, in which the user already gives the server the plaintext password. Examples for good use are the classical http form, or irc, an example for a bad use is a password change dialog inside formspec. Users should be aware that they lose the advantages of the SRP protocol if they enter their passwords for servers outside the normal entry box, like in in-game formspec menus, or through irc /msg s, This patch also fixes an auth.h mistake which has mixed up the order of params inside the decode_srp_verifier_and_salt function.

* Particles: Add option to remove particles on collisionAuke Kok2016-05-28
| | | | | | | | | | | | | | | | | | | | | | | | | Adds the particle option `collision_removal = bool` Some particles are hard to use right now since they either go through solid blocks (without collision detection), and with collision detection enabled they (e.g. raindrops) would just stop dead on the floor and sit there until they expire, or worse, scrape along a wall or ceiling. We can solve the problem by adding a boolean flag that tells the particle to be removed if it ever collides with something. This will make it easier to add rain that doesn't fall through your roof or stick on the top of it. Or clouds and smoke that don't go through trees. Particles that collide with this flag are marked expired unconditionally, causing them to be treated like normal expired particles and cleaned up normally. Documentation is adjusted accordingly. An added bonus of this patch is that particles can potentially collide many times with nodes, and this reduces the amount of collisions to 1 (max), which may end up reducing particle load on the client.

* Fix undefined evaluation order when constructing random vectorskwolekr2016-05-27
| | | | | | | | | | | | | | MSVC and GCC evaluate parameters in right-to-left order, whereas Clang evaluates in left-to-right order, and of course, an optimization could leave the order of evaluation completely indeterminate. This commit fixes all instances of the error by explicitly assigning the results of expressions that use PseudoRandom::next() or range() to their respective vector components. The right-to-left evaluation behavior is preserved since Clang is much less commonly used to compile Minetest than GCC and MSVC combined, and would therefore cause the least harm.

* Tolerate packet reordering in the early init processest312016-05-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fixes a bug where packet reordering made the server give the client two peer ids instead of one. This in turn confused reliable packet sending and made connecting to the server fail. The client usually sends three packets at init: one "dummy" packet consisting of two 0 bytes, and the init packet as well as its legacy counterpart. The last one can be turned off since commit af30183124d40a969040d7de4b3a487feec466e4, but this is of lower relevance for the bug. The relevant part here is that network packet reorder (which is a normal occurence) can make the packets reach the server in different order. If reorder puts the dummy packet further behind, the following would happen before the patch: 1. The server will get one of the init packets on channel 1 and assign the client a peer id, as the packet will have zero as peer id. 2. The server sends a CONTROLTYPE_SET_PEER_ID packet to inform the client of the peer id. 3. The next packet from the client will contain the peer id set by the server. 4. The server sets the m_has_sent_with_id member for the client's peer structure to true. 5. Now the dummy packet arrives. It has a peer id of zero, therefore the server searches whether it already has a peer id for the address the packet was sent from. The search fails because m_has_sent_with_id was set to true and the server only searched for peers with m_has_sent_with_id set to false. 6. In a working setup, the server would assign the dummy packet to the correct peer id. However the server instead now assigns a second peer id and peer structure to the peer, and assign the packet to that new peer. 7. In order to inform the peer of its peer id, the server sends a CONTROLTYPE_SET_PEER_ID command packet, reliably, to the peer. This packet uses the new peer id. 8. The client sends an ack to that packet, not with the new peer id but with the peer id sent in 2. 9. This packet reaches the server, but it drops the ACK as the peer id does not map to any un-ACK-ed packets with that seqnum. The same time, the server still waits for an ACK with the new peer id, which of course won't come. This causes the server to periodically re-try sending that packet, and the client ACKing it each time. Steps 7-9 cause annoyances and erroneous output, but don't cause the connection failure itself. The actual mistake that causes the connection failure happens in 6: The server does not assign the dummy packet to the correct peer, but to a newly created one. Therefore, all further packets sent by the client on channel 0 are now buffered by the server as it waits for the dummy packet to reach the peer, which of course doesn't happen as the server assigned that packet to the second peer it created for the client. This makes the connection code indefinitely buffer the TOSERVER_CLIENT_READY packet, not passing it to higher level code, which stalls the continuation of the further init process indefinitely and causes the actual bug. Maybe this can be caused by reordered init packets as well, the only studied case was where network has reliably reordered the dummy packet to get sent after the init packets. The patch fixes the bug by not ignoring peers where m_has_sent_with_id has been set anymore. The other changes of the patch are just cleanups of unused methods and fields and additional explanatory comments. One could think of alternate ways to fix the bug: * The client could simply take the new peer id and continue communicating with that. This is however worse than the fix as it requires the peer id set command to be sent reliably (which currently happens, but it cant be changed anymore). Also, such a change would require both server and client to be patched in order for the bug to be fixed, as right now the client ignores peer id set commands after the peer id is different from PEER_ID_INEXISTENT and the server requires modification too to change the peer id internally. And, most importantly, right now we guarantee higher level server code that the peer id for a certain peer does not change. This guarantee would have to be broken, and it would require much larger changes to the server than this patch means. * One could stop sending the dummy packet. One may be unsure whether this is a good idea, as the meaning of the dummy packet is not known (it might be there for something important), and as it is possible that the init packets may cause this problem as well (although it may be possible too that they can't cause this). Thanks to @auouymous who had originally reported this bug and who has helped patiently in finding its cause.
