clock_gettime() is a far better clock than gettimeofday().
Even better than clock_gettime() is that you can select either
CLOCK_MONOTONIC, or even CLOCK_MONOTONIC_RAW. These clocks offer
high precision time. And the _RAW variant will never roll back
due to NTP drift or daylight savings, or otherwise.
I've adjusted this code to select the right clock method auto-
matically based on what's available in the OS. This means that
if you're running a very old linux version, MacOS or other,
you will automatically get the best clocksource available.
I've tested all Linux clocksources by selectively compiling and
running a 10k+ timer test suite. In all cases I confirmed that
the 3 POSIX Linux clocksources worked properly, and were
selected properly.
I've modified the OS X compile path to use the high-res clock
source for all time functions, but I can't confirm it works or
that it compiles.
As for WIN32, I confirmed that the used clocksource is indeed
a Monotonic clocksource, so good news: that code section appears
to be exactly what it should be.
`errorstream` must not be overly verbose as clientside it is directly printed
onto the ingame chat window. These days, the serverlist can contain > 200k bytes,
so better print it to warningstream if the data buffer is too long.
Outdated servers are always sending tiledefs with culling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
Backface culling is enabled by default for all tiles, as this
is how the lua parser initializes each tiledef. We revert to
always using the value from the tiledef since it is always
read and serialized.
Mods that wish to enable culling for e.g. mesh nodes, now can
specify the following to enable backface culling:
tiles = {{ name = "tex.png", backface_culling = true }},
Note the double '{' and use of 'name' key here! In the same
fashion, backface_culling can be disabled for any node now.
I've tested this against the new door models and this properly
allows me to disable culling per node. I've also tested this
against my crops mod which uses mesh nodes where culling needs
to be disabled, and tested also with plantlike drawtype nodes
where we want this to continue to be disabled.
No default setting has changed. The defaults are just migrated
from nodedef.cpp to c_content.cpp.
cloneMesh() has to use a switch in order to create a different
mesh buffer type depending on vertex type. (Credit: the new cloneMesh
was written by RealBadAngel.)
To avoid repetitive code, all other methods use getVertexPitchFromType()
to automatically adapt the indexing to the vertex type at runtime.
The pageflip mode requires a stereo quadbuffer, and a modern graphic
card. Patch tested with NVidia 3D Vision.
The mini-map is not drawn, but that's what is done for topbottom and
sidebyside modes as well.
Also most of the time the user would prefer the HUD to be off. That's
for the user to decide though, and toggle it manually.
Finally, the interocular distance (aka eye separation) is twice as much
as the "3d_paralax_strength" settings. I find this a strange design
decision. I didn't want to chance this though, since it's how the other
3d modes interpret this settings.
Previously, we assumed that reply->str was NULL
terminated. However, this turned out to be not true,
as users reported crashes in strlen connected to
where reply->str was appended to an std::string.
Use the method recomended by the docs, to read the
length separately.
Removing the target file on other platforms was enabled likely unintentionally
by commit 5f1f1151d3a9c113902630adc16cc3f4845da7ba.
This may be the reason why there has been corruption of files on Linux on hard
shutdowns.
Previously I described the problem and this fix in issue #3084.
My commit
e2d54c9f9275e4f77ec33be8054621d42945f7a4 "shutdown when requested from lua in singleplayer too"
broke minetest's feature to connect to servers. The client crashed
after the connection init was complete.
Thanks to @sofar for reporting the bug.
Fixes#3498.
If an `XDG_CACHE_HOME` can't be found or `RUN_IN_PLACE` is enabled,
`path_cache` is left at its default of `$PATH_USER/cache`
(at a time when `PATH_USER` is `..`), rather than being reset to
`$PATH_USER/cache` after `PATH_USER` has been properly set.
This allows other applications (e.g. minetestmapper) to interrogate
the database while minetest is running, without causing an almost
certain minetest crash.

Fixes#3362.
Fix regression of commit
5e507c9829942c434a6f1ae7a4f3a488c7e50bef "Add server side ncurses terminal"
where no line termination character was printed after a
lua print outside of terminal mode.
Fixes#3350.
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.
The Atomic implementation was only partially correct, and was very complex.
Use locks for sake of simplicity, following KISS principle.
Only remaining atomic operation use is time of day speed, because that
really is only read + written.
Also fixes a bug with m_time_conversion_skew only being decremented, never
incremented (Regresion from previous commit).
atomic.h changes:
* Add GenericAtomic<T> class for non-integral types like floats.
* Remove some last remainders from atomic.h of the volatile use.
It isn't possible to use atomic operations for floats, so don't use them there.
Having a lock is good out of other reasons too, because this way the float time
and the integer time both match, and can't get different values in a race,
e.g. when two setTimeofDay() get executed simultaneously.
Cleanup:
* Remove volatile keyword, it is of no use at all. [1]
* Remove the enable_if stuff. It had no use either.
The most likely explanation why the enable_if stuff was there is that it
was used as something like a STATIC_ASSERT to verify that sizeof(T) is not larger
than sizeof(void *). This check however is not just misplaced in a place where we
already use a lock, it isn't needed at all, as gcc will just generate a call to
to the runtime if it compiles for platforms that don't support atomic instructions.
The runtime will then most likely use locks.
Code style fixes:
* Prefix name of the mutex
* Line everything up nicely, where it makes things look nice
* Filling \ continuations with spaces is code style rule
Added operations on the atomic var:
* Compare and swap
* Swap
The second point of the cleanup also fixes the Android build of the next commit.

On Windows Release x64 bit build this changes:
ProfilerGraph::put
1.68% -> 0.061%
ProfilerGraph::draw
12% -> 17.%
So yes, there is a tradeoff between saving profiling data
(executed always) and drawing the profiler graph (executed very rarely).
But usually you don't have the profiler graph open.
For several years now, the lua script lock has been completely broken.
This commit fixes the main issue (creation of a temporary rather than
scoped object), and fixes a subsequent deadlock issue caused by
nested script API calls by adding support for recursive mutexes.
When compiled with optimizations, the most recent versions of clang seem
to 'optimize' out a crucial "and %reg, 0x7FFFFFFF" instruction in noise2d(),
probably because it somehow assumed the variable n would never become greater
than that amount.
Indeed, signed integer underflow is undefined behavior in C and C++, so while
this optimization is "correct" in that sense, it breaks lots of existing code.
Solved by changing n to an unsigned type, making behavior well-defined.
Previously, the server called FATAL_ERROR when a Lua error occured.
This caused a (mostly useless) core dump.
The server now simply throws an exception, which is caught and printed before
exiting with a non-zero return value.
This also fixes a number of instances where errors were logged multiple times.

Use this macro to disallow copying of an object using the assignment
operator or copy constructor. This catches otherwise silent-but-deadly
mistakes such as "ServerMap map = env->getMap();" at compile time.
If so desired, it is still possible to copy a class, but it now requires
an explicit call to memcpy or std::copy.

Previously, the invocation of Logger::addOutput(ILogOutput *out) led to
an out of bounds write of the m_outputs vector, resulting in the
m_silenced_levels array being modified.
Fortunately, the only caller of that method was android system logging,
and only since a few commits ago.
-> Get rid of Logger::logToSystem and use normal downstream output system for android instead
-> Give the downstream output system more information: enrich the log function of ILogOutput
with information and add ICombinedLogOutput for easier use.
-> Make Logger::getLevelLabel() static and public so that it can be used by downstream log output.
-> Add g_ and m_ prefixes where required
* Add key settings to setting table and ignore them later

Flushes the buffer of rollback actions that wait to get saved in two more situations:
1. Flushes in the destructor of the rollback. This makes the server not
forget the last < 500 rollback entries when it shuts down.
2. Flushes the rollback when /rollback_check is invoked. This is neccessary
as otherwise it leads to confusion if users want to test the rollback functionality
by placing a node and then executing the check on it, or if the actions were
very recent out of other reasons.
Everywhere where wstrgettext was used, its output was converted back
to utf8. As wstrgettext internally converts the return value
from utf8 to wstring, it has been a waste. Remove the function, and
use strgettext instead.
- setOpenedTrees(): this internal function was calling setSelected()
to update m_selected. Since setSelected() calls autoScroll(),
this caused the scrollbar to scroll back to the selected row
in some cases when that shouldn't be done.
For example, clicking the "+" to open a tree caused autoscroll.
Fix this by making setOpenedTrees() modify m_selected directly.
- setDynamicData(): set scrollbar position after calling
setSelected(), not before. This avoids setSelected()'s autoscroll
messing up the scrollbar position again.
- setSelected(): If an invisible row is selected, open all parents
of the selected row in order to make the selected row visible.
This fixes the issue where all the trees are closed again whenever
you return from the setting edit dialog to the settings tab.

The invsize formspec element is outdated. Even though,
it is still supported, only a deprecation warning is shown,
introduced by commit [1]. The lua context passed to the
log_deprecated method added by commit [1] is NULL for the
invsize deprecation warning, as its run on the client and not
the server.
Commit [1] has removed checks for NULL inside the log_deprecated
method, resulting in a crash when a formspec with an invsize
element is parsed. This commit puts the check back.
Fixes#3260.
