It turns out there is no need to return the new value and
preserve the old one in random_turn, the procedure can be
made to modify the value in-place. This saves quite a bunch
of parameter and return value copying.
Previously, when basic shaders were enabled, the function
time_to_daynight_ratio() returned values jumping between 149 and 150
between times 4375 and 4625, and values jumping between 999 and 1000
between times 6125 and 6375, (and the corresponding times at sunset)
due to tiny float errors in the interpolation code.
This caused the light level returned by blend_light() to jump between
14 and 15, which became noticeable recently as those light levels were
given different visual brightnesses.
Add early returns to avoid the problematic interpolation, and to
avoid unnecessary running of the loop.
Makes the liquid waving shader per-nodedef like waving leaves/plants,
instead of being applied to all liquids.
Like the waving leaves/plants shaders, the liquid waving shader can
also be applied to meshes and nodeboxes.
Derived from a PR by t0ny2.
Like randomwalk caves, preserve nodes that have 'is_ground_content = false',
to avoid dungeons that generate out beyond the edge of a mapchunk destroying
nodes added by mods in 'register_on_generated()'.
Issue discovered by, and original PR by, argyle77.
This change permits to use up-to-date compilers, clang-tidy and
clang-format
It also refactor the tidy/format step to drop the binary selection from
scripts and perform it directly in travis
Shorter, simpler, clearer and more consistent with other mapgens,
while preserving functionality.
Base terrain shape is unchanged.
With the 'vary river depth' option disabled, river surface level
is unchanged.
Behaviour of the 4 heat/humidity/river depth options is very
slightly changed due to bugfixes and code cleanup (the mapgen is
'unstable').
Apply heat and humidity gradients above water_level instead of
above y = 0.
I removed the MapNode constructor which takes a nodename and gives the node's id or CONTENT_IGNORE
The code which used this constructor (two places) now handles the situation of not registered nodes correctly:
* minetest.set_node and similar functions make minetest crash when a not registered node is passed
* reverting a node with rollback aborts if the node is not registered
Use "append" method to construct the various game paths
instead of wasteful string concatenation. Additionally, use a
temporary to extract and reuse a result of a few common
subexpressions to further reduce the overhead.
The "what" parameter is being passed by value, most likely by
accident as the type is "const std::string". Convert it to a
reference by adding the missing "&".
* Fix color command line parameter ignorance

* Allow adjusting the log color with an environment variable
If --color is not passed to minetest, is used to decide on the log colorization.
Minetest settings can not be used instead of an environment variable because logs may appear before loading them.
* fix empty if body
This loop makes multiple passes over m_stack (type std::list) in order to remove all elements with a specified value. Replacing the loop with a call to std::list::remove does the same job, but in only one pass.
This sends the following header to a remote media server:
Referer: minetest://<server_name>:port
This was verified with CTF and the Minetest Public Remove Media
server. If the servername was a plain IPv6 address it will
contain `:` characters and will be encapsulated in `[]` to
be a valid URI.
The getS16NoEx() handler will return true unless there is a
`[num_emerge_threads]` line in the `minetest.conf` at which
point the excption handler part is reached. Due to the fact that
`defaultsettings.cpp` has a default value set for this setting,
that never will happen.
Because of this, the code will never check the number of threads on
the system, and keep `nthreads = 0`. If that happens, the value is
changed to `1` and only 1 emerge thread will be used.
The default should be set to `1` instead, due to the potential unsafe
consequences for the standard sqlite map files, but that should be a
separate commit that also adds documentation for that setting. This
commit focuses on removing this `hiding` bug instead.
* Drop the ID mapper, use a big u64 instead. This will permit to resync server ids properly with the manager code
* Modernize some code parts (std::unordered_map, auto)

The reverted commit 968ce9af598024ec71e9ffb2d15c3997a13ad754
is suspected (through the use of bisection) of causing network slowdowns.
Revert for now as we are close to release.
Store the rotation in the node as a 4x4 transformation matrix internally (through IDummyTransformationSceneNode), which allows more manipulations without losing precision or having gimbal lock issues.
Network rotation is still transmitted as Eulers, though, not as matrix. But it will stay this way in 5.0.
Previously, when using 'place on vmanip' to add a schematic to a
lua voxelmanip, if part of the schematic was outside the voxelmanip
volume, the outside part would often appear in a strange place
elsewhere inside the voxelmanip instead of being trimmed off.
This was due to the out-of-bounds check checking the index.
A position outside the voxelmanip can have an index that satisfies
'0 <= index <= voxelmanip volume', causing the node to be placed
at a strange position inside the voxelmanip.
Use 'vm->m_area.contains(pos)' instead.
Move index calculation to later in the code to optimise.
If a formspec is submitted from a form fields handling
callback of another form (or "formspec shown from another
formspec"), the fields submitted for it can get
rejected by the form exploit mitigation subsystem with a
message like "'zorman2000' submitted formspec
('formspec_error:form2') but server hasn't sent formspec to
client, possible exploitation attempt" being sent to logs.
This was already reported as #7374 and a change was made
that fixed the simple testcase included with that bug
report but the bug still kept lurking around and popping
out in more complicated scenarios like the advtrains TSS
route programming UI.
Deep investigation of the problem revealed that this
sequence of events is entirely possible and leads to the
bug:
1. Server: show form1
2. Client *shows form1*
3. Client: submits form1
4. Server: show form2
5. Client: says form1 closed
6. Client *shows form2*
7. Client: submits form2
What happens inside the code is that when the server in
step 4 sends form2, the registry of opened forms is
updated to reflect the fact that form2 is now the valid
form for the client to submit. Then when in step 5 client
says "form1 was closed", the exploit mitigation subsystem
code deletes the registry entry for the client without
bothering to check whether the form client says was
closed just now is indeed the form that is recorded in
that entry as the valid form. Then later, in step 7 the
client tries to submit its valid form fields, these will
be rejected because the entry is missing.
It turns out the procedure where the broken code resides
already gets the form name so a simple "if" around the
offending piece of code fixes the whole thing. And
advtrains TSS agrees with that.
Reserve space for the list of games in findWorldSubgame. The
performance gain is pretty much negligible but this change
also gets rid of a performance warning by CLANG TIDY.
This patch will make distinguishable mods in modpacks possible in the future
`nil` checks are required to provide backwards-compatibility for fresh configured worlds
The craft definition handling code that collects the names of
the craftable nodes suffers from vector reallocation
performance hits, slowing down instances with lots of
crafting recipes (VanessaE's DreamBuilder and most public
server some to my mind when thinking about this). As in each
instance the size of the resulting vector is already known,
add a reserve() call before the offending loops to allocate
the needed chunk of memory within the result vector in one
go, getting rid of the overhead.
The pathfinder needs quite a bunch of items to add to the
resulting list. It turns out the amount of the space needed
for the finalized path is known in advance so preallocate it
to avoid a burst of reallocation calls each time something
needs to look for a path.

The fallback code shouldn't be needed and is a remnant of the GET
method that old media servers use. Clients using it are likely
to just waste bandwidth and having to download the media again
through the normal transfer from server method. The most reliable
method is to get all missing textures therefore from the server
directly and not spam the remote media server with 404s.
Previously, when the CSM restriction 'LOAD_CLIENT_MODS' was used a
client was still able to add CSM code to 'builtin' to bypass that
restriction, because 'builtin' is not yet verified.
Until server-sent CSM and verifying of 'builtin' are complete, make
'LOAD_CLIENT_MODS' disable the loading of builtin.
Clarify code comments and messages to distinguish between client-side
modding and client-side scripting. 'Scripting' includes 'builtin',
'modding' does not.
GCC and CLang compilers fail to support full IEC559 compliance required for the test, when certain compiler flags are active. This patch implements a heuristic that checks for the most common flag in GCC and CLang, plues an extra check which GCC disables when it's not compliant, to hopefully catch most cases where it can't run.

At sunset:
Stars first appear slightly later, at the time the sun disappears over the horizon,
this fixes seeing dark stars in front of the sun horizon glow texture.
Stars reach full brightness slightly earlier at time 20000, not so excessively long
after sunset.
The above behaviour is also applied at sunrise, but of course, time-inverted.
In pitch fly mode, you fly to the exact direction you are pointing at, using the forward key. Other move directions are also pitched accordingly.
It allows smoother and more complex movements.
Can be enabled/disabled by L key by default (set keymap_pitchfly in minetest.conf)
script_get_backtrace() was leaving its return value on the stack, corrupting
subsequent lua operations for functions that did not immediately return.
This problem can specifically be observed in the case of multiple "groupcaps"
entries, each of which provides the legacy "maxwear" property. These cause a
backtrace and thus pollute the stack for the following lua_next() call.
* Adds Lua methods 'set_rotation()' and 'get_rotation'. Also changed some method names to be more clear. Instead of an f32 being sent over network for yaw, now a v3f is sent for rotation on xyz axes. Perserved Lua method set_yaw/setyaw so that old mods still work, other wise to set yaw they would need to switch to set_rotation(0, yaw, 0).

Previously, 'time_brightness' never fell below the threshold so
night sky colours were not applied.
Increase the threshold value. But now also set it to a value less

Previously, night clouds were almost indistinguishable from night sky,
especially since a recent commit that made night sky brighter.
They were lacking the beautiful luminosity caused by being lit by the
permanently-full moon.
When 'directional_colored_fog = false' allow the dawn/dusk cloud
brightness boost to apply through the night too.
Set an identical minimum cloud brightness for when
'directional_colored_fog = true'.
Damage flash is shortened from 0.98-1.27s to 0.25s-0.33s to reduce
player in-game blindness, especially useful for combat situations.
It is also visually more comfortable.
Camera hurt tilt is made slightly shorter to match in duration.
Both flash and camera tilt are now of similar length to a typical
damage sound, such as the one used by Minetest Game which is 0.27s.
The 3 effects become more synchronised and unified.
Previously dungeons > decorations > ores.
Decorations depend on the node they are placed on, and ore types are
increasingly able to place large continuous volumes of nodes, such as
strata. Decorations are increasingly being used underground.
The new order avoids a node being changed by ore generation after a
decoration has been placed on it.
The new order also avoids ores appearing in the walls of a dungeon if
the wall nodes match the local stone node.
Make tunnels wider and use the noise parameters of most other mapgens.
All other underground features are already identical to all other
non-mgv6 mapgens, this final change modernises and improves the tunnels.
Also, use a better distance calculation for 'collide with objects'.

Some cave segments are outside the mapchunk.
Previously, biome was being calculated by a function that uses the noise
maps. Points outside the mapchunk resulted in incorrect noise map indexes
that were sometimes outside the noise map size, causing a crash.
Use either noise maps or point noise calculations depending on point
location.
When the noise value or fill_ratio >= 10.0 complete coverage is enabled.
This disables random placement to avoid redundant multiple placements
at one position. Instead, 1 decoration per surface node is placed by
looping across each division.
'10' was chosen as this is the fill_ratio that previously created
very near complete coverage. The complete coverage feature therefore
integrates smoothly when noise is used for variable decoration density.
'fill_ratio = 10' should be used by modders who want a decoration
placed on every surface node. Compared to before such a decoration
placement will be 10 times faster.
* Few code updates

Previously, the biomemap was 'BIOME_NONE' for a mapchunk column if a
stone surface was not found in it, causing water surface decorations
and water surface dust to fail.
Store the biome ID of the biome calculated at a water surface and add
it to the biomemap if the biomemap is 'BIOME_NONE' for the mapchunk
column. The biome calculated at a stone surface still has priority
for the biomemap entry, as it should.

f4ca830abe1aa22875c99b31bf2ee56e26f83f05.
These commits caused biome dust to be applied even when there was no core
mapgen terrain in a mapchunk column. So the dust, which overgenerates,
then appeared on structures added by mods in 'on_generated', such as
floatlands, asteroids or above-surface realms.

Previously the only way to disable biomes was to 'clear' the registered
biomes in a mod, but this method causes large amounts of unnecessary
processing:
1. Calculation of 4 2D noises.
2. Looping through all nodes of a mapchunk replacing nodes with identical
nodes.
The new flag disables those operations.
'generateBiomes()' constructs the biomemap as it generates biomes.
The biome calculated at first stone surface encountered is added to
the biomemap.
Previously, if no stone surface was encountered in a mapchunk column
the biomemap was left empty for that (x, z) position, causing biome
dust and water surface decoration placement to fail.
If at the base of a mapchunk column the biomemap is empty, add the
currently active biome to the biomemap, or if biome is NULL calculate
it for this position and add it to the biomemap.
In some configurations, such as when using the runit supervisor and its
tool chpst, the HOME variable might be unset. This resulted in an
unclear error message that was hard to pin down.

Because vein ore uses 3D noise (all the other ores use 2D noise) the
perlinmap Y size can be different in different mapchunks when close
to the ore Y limits.
Previously this caused bugs in the vein structure because changes in
perlinmap Y size did not recreate the noise objects.
Delete and recreate the noise objects with the new Y size if Y size
has changed.
Previously, the centering caused by the 'place center x/z' flags did
not take rotation into account. So schematics with unequal X and Z
dimensions were incorrectly placed. The bug was hidden for schematics
equal in X and Z dimensions.
