Allow modules to define an unload callback, and also drive
the 'loaded' property to false, to give modules the ability to clean
up when being unloaded. This makes reloading work without
errors for Canvas.
Additionaally, add some special code when creating the
Canvas module, to ensure the C++ defined pieces are loaded :
fortunately Canvas is the only module which needs this.
gcc on riscv64 is not able to compile natively atomic int, because of hw constraints, leading
to an additional to link external atomic libraries, making the code really slower to run.
Instead, using std::atomic<int> can be compiled and optimized natively without any additional -latomic linking.
Previously WS30 data from STG files - in particular road/rail/river
data - was kept permanently.
This change unloads it with the STG-level tile. This is the right
level to do so, as it will be reloaded from tile when the STG file
is loaded again.
Previously we were hardcoded to 2 database pager threads,
one for files and one for http.
This commit adds a new property /sim/rendering/database-pager/threads
to control the number of threads on startup.
It also re-orders the code to set the database pager so that such
a setting has an effect.
Change all constant numeric values with the defined constant.
Changed the wrong '*offset-m' properties and the 'rollspeed-ms' property.
Maybe the wrong offset properties hasnt popped up because no dev used
it. This value will not be used in any animation because its normally a
fixed value that doesnt change at runtime.
With this patch, the dev can set <max-compression-ft> or <max-compression-m> in the set-file (or another
xml-file that get included from the set-file).
The code calculates also 'compression-m' for every gear.
If the 'max-compression-*' property is omitted, the code behave as before ('compression-norm' is the same as 'compression-ft').
Some of the subsystems created in the fg_init fgCreateSubsystems() function were accidentally
shifted into the subsystem group SGSubsystemMgr::GENERAL, as these subsystems cannot be currently
registered with the subsystem manager and still have to use the non-templated subsystem manager
add() function.
Previously any missing WS30 tiles created multiple OSG WARN
messages from the file not being found. This change does a check
to ensure the file actually exists before put it on the queue for
loading.
AI models have rudimentary collision detection with submodels that performs two tests.
1. The height difference must be less than a defined amount
2. The centre point range must be less than a defined amount.
(2) above by itself would result in a spherical comparison; however (1) effectively modifies this to slice off the top and bottom of the sphere so that the sphere heigh is half of the value in (1).
Previously these heights and lengths were hardcoded - this change allows these to be defined in the xml instead using the <collision-length> and <collision-height> tags
e.g.
<entry>
<type>ship</type>
<collision-length type="double">50</collision-length>
<collision-height type="double">50</collision-height>
</entry>
Default values:
+---------------+-------------+------------+
| Type | Height(m) | Length(m) |
+---------------+-------------+------------+
| Null | 0 | 0 |
| Aircraft | 50 | 100 |
| Ship | 100 | 200 |
| Carrier | 250 | 750 |
| Ballistic | 0 | 0 |
| Rocket | 100 | 50 |
| Storm | 0 | 0 |
| Thermal | 0 | 0 |
| Static | 50 | 200 |
| Wingman | 50 | 100 |
| GroundVehicle | 20 | 40 |
| Escort | 100 | 200 |
| Multiplayer | 50 | 100 |

This covers all instantiated SGSubsystem derived classes, i.e. those that are
not base classes, including subsystem groups. Both non-instanced and instanced
subsystem creation is tested. The tests for subsystems yet to be registered are
commented out.
Most subsystems are now created via the subsystem manager using the global
subsystem registrations.
The FGGlobals add_subsystem() and add_new_subsystem() methods have been removed
as the subsystem manager addition and creation function interface now exceeds
the functionality of these helper functions.
- The program name is fgfs_test_suite, not run_test_suite.
- Add three examples for particularly useful tasks; be explicit about
how to discover available test names.
- std::endl flushes the stream every time it is used; better use '\n'
in most places (more efficient and takes less space on screen). :-)
- Fix a little regression introduced in commit d2f4807fa2: changing
the standby frequency disabled the low-pass filter for the next call
to updateReceiver(); this must happen when the selected frequency is
changed but not when the standby frequency is changed. This is covered
by the recently-added unit test NavRadioTests::testVORSignalQuality.
- Optimization of the older code: no need to perform a navaid search()
when only the standby frequency is changed.
When the selected frequency is changed or when leaving GPS slave mode,
disable the low-pass filter applied to signal quality. Otherwise, the
following may happen for instance:
- the active frequency corresponds to a navaid whose signal is well
received;
- user makes it so that the Morse code for the navaid ID can be heard;
- user then changes the selected frequency to one that doesn't belong
to a navaid that is close enough to be usable;
- yet, as soon as the frequency is changed, the Morse code for the ID
of the newly selected navaid (if any), even if it is way too far for
its signal to be received, will be very clearly heard for about one
second---and likely truncated.
This is because before this commit, after the frequency change, the
low-pass filter applied to signal quality made the code behave as if the
signal, supposedly coming from the new navaid, were still strong---which
of course doesn't correspond to physical reality. This fixes the bug
reported at [1].
