Many light aircraft include GPS loggers capable of recording the flight
path using IGC records. Lots of third party utilities are available to
analyze, process and convert igc files.
Usage: "fgfs --igc=file,out,1,OutputFile.igc"
If an invalid filter type is supplied, don't run the queries.
This showed up with GPS dialog, since the PUI combo box defaults to
no entry selected, not the first entry.
Using a new TerraSync API, make the tile manager wait on actively
syncing tiles before sending them to the SceneryPager. This resolves numerous
issues with missing tiles, including at startup.
- Enable the terrasync persistent cache
- Ensure terraysync scenery dirs exist before NavCache init, so the paths are stable
- Notify TerraSync on reposition, so we sync the full 3x3 set of tiles.
Move sqlite source to a separate location, and build with
an intermediate library target. This permits us to set compile options
easier, including an important one, NDEBUG, which improves performance.
Sqlite 3.8.0.2 also includes an updated query planner which may improve
some queries, to be tested.
Simgear contains a new helper to validate format
strings for potentially dangerous replacements, use
it to fix the issues raised by Debian bug trackers.
add checks against buffer overruns
CVE-2012-2091 mentions various buffer overruns in simgear and
flightgear. This patch addresses this issue in Rotor::getValueforFGSet().
From: Tom Callaway
Range for special freq was computed with previous freq, now they are always in range
Use a global variable (_currentFreqKhz) in order to avoid a <static_cast> in main loop; now it's only on frequency change
Fix a .size() > 0 for !.empty()
This logic was only ever causing bad values, all callers which care
about an altitude restriction were setting one explicitly. Thanks to
Curt for spotting it.
As part of this, kill off the evil global FDM state, and avoid us
copying FGInterfaces (which is bad since it contains TiedProperties
and an FGGroundCache, neither of which are especially keen on being
copied). Will probably disable copy/assignment on TiedProperties in
a future commit.
rwyprefs.xml sometimes specify runways without a leading '0', which
confuses the ident lookup. Print a message, and fix up such idents at
load time, so '8' -> '08', '3L' -> '03L' which matches our internal
scheme.
This is a work-around, probably indicates some glitch in the traffic
module flight-plans. Avoid a crash, also refine the exception logic
so individual AI objects can fail.
Bounding box wasn't being dirtied when changing the transform,
breaking picking visitor for the panel. Add listeners to the relevant
props so we can tell OSG when the panel transform changes.
Adding a spherical projection mode which will work at the poles and
+180/-180 line correctly. Not yet enabled since it has other issues to
be addressed.
This reverts commit 91ae41f9ef.
We do not need this as outputs already are written to the property
tree and most intermediate values can easily be calculated
manually.
For 2.12, ensure all GPS instruments are backwards
compatible, however they were requested. Post release we can create a new instrument name with the compatibility code disabled.
canvas::Window now optionally creates a second canvas for showing
window decoration. After setting its dimensions with the property
"decoration-border" a Nasal based window decorator should add the
required elements to the decoration canvas.
Using the properties "shadow-radius" and "shadow-inset" a drop
shadow can be added to the window.
Nick Vatamaniuc: fix AI aircraft not updating waypoint headings when using custom flightplans.
(Commented out log-line following a non-parenthesised if() test causing problems)
There's a sufficiently large installed base, that simply dropping this
API is not acceptable. A Nasal shim might be possible, but in the
interim, restore the C++ functionality.
Route-manager was explicitly deleting its FP, which was incorrect.
Switch to correct use of SGSharedPtr to refer to flight plans.
Thanks to Roland Haeder for catching this.
Generic transponder can emulate KT-70 props. These emulated props
will likely die in the future, based on feedback from aircraft devs.
See (upcoming) Wiki docs on the transponder for more info.
- Add option 'capture-events' to canvas aircraft and scenery
placements to allow events being forwarded to the respective
canvas.
- Clean up and restructure parts of the mouse event/picking
handling to support forwarding events to canvasses.
All methods exposed to the Nasal props module now accept an
optional first parameter refering to another node by a relative
path.
(Thanks to Philosopher for the initial patch)
Avoid horrible startup times for Windows users. It would be good
if someone with a Windows box, debug environment and some time could
investigate further.
If you want a scenario in a particular session of the sim, ask for
it on the command line / config files, or enable in the GUI.
Note if you had previously 'sticky' scenarios in your autosave.xml, you
will still get them until you clean your autosave, or disable them in
the GUI.
Respect the user's language selection in the system settings, and try those languages in turn. If a language is explicitly specified, try that first regardless.
This allows Nasal code attached to scenery models access their
world position and orientation by calling _model.getPose().
Also ensure models are attached to the scenegraph before Nasal
load scripts are called. This ensures that the world position
and orientation are available upon executing the load script.
Allow for advanced animations using easing functions and adapters
for interpolating specific property types (eg. CSS colors).
Old behavior should not have changed.
Ensure canvas displayed inside GUI windows are updated in the same
frame as the according window is made visible. This prevents
showing previous contents for the first frame.
This gives nice cursors when hovering and dragging slider and knob-animations, and the cursor is set correctly on mouse-up after the drag too. Makes directional knobs/sliders much easier to understand.
Ensure all FGPositioned related functions return SGSharedPtr
instead of raw pointers to allow automatic conversion to
nasal ghosts without custom helper functions.
Some cockpits rely on mouse position props being updated even when using a dragged pick-callback. Thanks to Clement for noticing. Re-structured so however we process the mouse (PUI, pick-callback, normal motion), we always update the props.
This adds the framework for platform cursor implementations; Windows and X11 to be done.
It also extend the mouse-input code to generate hover events suitable for driving tooltips.
Note there should be no visible functionality change from this commit, since everything
is inactive until fgdata changes are made.
For now it is available in the positioned Nasal
module. FGAirport is fully ported, but especially
procedures/navaids and free functions are still
missing.
In preparation for adding POI data, extend the FGPositioned type enum, and the cache code to handle arbitrary POI types. (Adding more in the future is straightforward now)
Also support removing user waypoints, which was requested by the Garmin G196 developers.
This was a bogus concept, either runways have a reciprocal or not (if singled-ended), really this was simply exposing an artefact of the apt.dat encoding. Change to an API which gives what is actually wanted - the ability to extract an airport's runways without any reciprocals included.
This eliminates many conversations between ft and m and gives us runway start/end
points that are needed for many calculations. Also, this prepares the internals for
the upcoming apt.dat 850+ format that uses the metric system as well as start/end points.
When calling setILS, in-memory runways did not get updated. This showed up in the map, but also affecting a few other places. Will port this to 2.10.1 when that process starts.
When using the default (generic) config, which references many props which may not exist in a particular aircraft, suppress the 'recording non-existent' property warning.
Add a puaListBox which can show the contents of a log-buffer. Currently only two buffer sources are supported more to follow (and the dialog XML updates).
- Don't capture mouse events if mouse mode has
pass-through disabled. This behaviour is
consistent with the PUI dialogs and allows
changing moving view and controls while above
any GUI dialog.
- Add option to canvas windows to ignore all
events and let them pass through
("capture-events").
Instead of deleting all table contents, actually remove the entire file on disk and re-create. This is fractionally more work, but removes any possibility of stale indices or missing deletes causing clutter after rebuilds. My suspicion is, this is cause the erratic performance some people have seen with the airports search dialog, so will back-port to 2.10.
Comments in the code imply osgViewer always sends 'num-lock'-off codes, but that is not the observed behaviour with Cocoa. So adding mappings for the num-locked codes on Mac, which is what people actually want at the moment.
Enabling this hack by default, to assess the impact for everyone. Should fix the issue for Ati Catalyst 11.5 users, and hopefully no impact for everyone else. All feedback appreciated. Set /sim/ati-viewport-hack to false if you think this option might be causing issues for you (and then tell James, ASAP)
added measured-total-pressure property to account for a normal
shockwave in front of pitot tube at supersonic speeds. momentarily not
used
small unit conversion correction of inHg to hPa in altimeter
Base airspeed calculations on impact pressure in instrumentation
/airspeed_indicator
AndersG noticed an issue when a ground-net file is edited. The DROP commands prior to the reload were wrong, fixed now to delete all ground-net entries before the file is read.
KATL -> KLAX looks correct now. Great-circles that span the 180-meridian are still rendered wrong, but that's a map projection issues, which I will fix in the next few days.
This allows delegates to take action when the flightlan is cleared, and especially, for the default delegate in the route-manager to deactivate itself, and hence the GPS LEG mode - which fixes bug 940 I hope.
When leg spans more than a threshold (currently 0.5 degrees) of longitude, interpolate the actual path flown by the GPS/RM, which is a true great-circle. Previous we rendered a Rhumb line which does not agree at all. (Especially noticeable in the MapWidget and NavDisplay code, both of which use RoutePath to tesselate the route before rendering)
At large search ranges (320 or 640NM range on the 777), the search time can blow up, especially if distant airports are being loaded. Add a time-bounded spatial query, and use it, so performance stays tolerable.
When the from and to points are not on the enroute structure, check the initial and final legs for large turns (more than 90-degrees) from the overall route course. If found, kill the leg, to generate more natural route and avoid very sharp turns in the terminal area.
Note these are still generic and do NOT take local terrain into account. Don't come crying to me if you fly into nearby terrain because you weren't using a real procedure!
One of the two route termination conditions was improperly handled, leading to bad leg/wpt indices and exceptions from the GPS code. Detect passing the final waypoint in a more robust way now.
Also fix the GPS code to avoid turn computation on the final leg.
Clean-up how axes and button bindings are destroyed are re-built on reinit of the FGJoystickInput subsystem, so we get new, cleanly initialised items each time.
Allow the location of the ND centre to be set from properties instead of always using the acct position.
(I thought I'd supported this option long ago, evidently not)
Use a RAII object to manage cache transactions, and reset queries immediately after they are done, to avoid auto-commit transactions lasting long periods of time. Re-write the commit and step logic to handle SQLITE_BUSY, with progressively increasing waits when there is DB contention (multiple processes accessing the DB).
As an opt-in API, allow clients to request partial results, with a time-bounded cutoff. Use this to keep the MapWidget responsive even when many airports are being added to the cache (e.g., zooming out or panning rapidly when zoomed out)
Make position finalisation happen in the same phase as scenery load, i.e as a task during the main loop, instead of during the init loop. This is compatible with the existing reset logic. Unfortunately more work is needed; the environment code doesn't update the local station quickly enough on reset. (Fixing that is next!)
- Setting 'resize' property to true on canvas::Window shows
resize icons and exposes requested size to the property
tree. This can be used eg. from Nasal to actually resize
the window and/or show a preview of the resized window
while resizing.
- Event handling now ignores events which have already
been handled. Before eg. clicking inside a window
also caused picking to be performed inside the
scene which is for sure not the expected behaviour.
- Also forwards scroll wheel events from canvas::Window.
Record the historical flight-path (by default, since last takeoff). Optionally display the flight-path in the map; other visualisations (e.g., an 'in-world' view) could also be created. Nasal API to follow so Canvas-map or FMS can show the same data.
Altitude and attitude (Euler angles) are currently recorded but not used anywhere.
If the size of a Canvas changes also the texture id
changes. We now retrieve the texture id for the CanvasWidget
every frame to ensure it uses the latest texture instance.
Modify startup sequence, so position can be modified late in the startup process, right before the scenery load starts. This allows two ugly hacks to move to a permanent, less hacky location. If other position init modes required similar late evaluation in the future, this can be accommodated now.
This is a somewhat high-risk change - I've tested both carrier starts and runway-selection based on realwx METAR, but please look out for other position-init issues and test before / after this patch.
Disable elevation mixup for naiads, since it is introducing inconsistencies between the navdata and the scenery. (Actually it's exposing inconsistencies between the airport and navaid data, but that can't be fixed right now)
This bug was caused by the code not tolerating missing navaids / waypoints. Update logic so missing navaids degenerate to basic waypoints without problem. Also tolerate present, but empty, runway properties - don't throw an exception by looking up empty identifiers.
Iterator must be reset after clearing waypoint list.
Deleting "*waypoint.end()" doesn't delete the last waypoint (end()-1
does - it is never actually used though).
When the scenery paths change, we need to rebuild the nab-cache, since Airports/ data may have changed - e.g. someone installing custom scenery with updated ILS / thresholds.
When multiple processes (right now, multiple copies of fgfs, but potentially other users in the future) access the navcache, it can cause SQLite to return a 'locked' error, so the request should be re-tried. Add code to do this.
rather than window size, since the size of full screen windows can change:
e.g. Xinerama mode automatically resizes fullscreen windows to cover the
area belonging to a single display only - so the
"(Xinerama) screen area == window size" check always failed - even in
fullscreen mode.
PositionedID is of "int64_t", which depends on platform: apparently it is
"long long int" for Mac (requiring %lld format), but it is "long int" for
64bit Linux (requiring %ld). To avoid a "compiler warning fix commit
war" ;-) use a type cast to the longest common type (long long int).
Inspired by Harald's patch, attempt to get AI models show realistic gear animations. Unfortunately AI models seem to be ignoring the gear properties, so keeping the code disabled until I can trace down why.
FGAISchedule::update can be time consuming. Preempt when necessary to
avoid simulation lags, and call it every sim iteration, until the flight
plan is complete.
ThorstenB identified some cases where mod-times changing could lead to corrupted ground-cache data in the DB - handle both of these. What's still unclear is why the mod-times changes; hopefully the additional debug info will reveal this.
to avoid repeating identical NavCache/SQL queries. Also ensures we're
not using multiple FGAirport instances for an airport - each triggering
identical queries to pull in airport data.
Airports by ICAO ID are requested very frequently at run-time, so caching
significantly boosts performance.
Track length is calculate every iteration/for every aircraft. Since some
tracks have hundreds of waypoints, calculation is slow. Cache the
track length between the waypoints ahead, so it rarely needs to be
recalculated.
AIManager had unfortunate code to pass some state to the traffic-manager; this is no longer required since traffic schedules hold onto their AI-Aircraft directly as needed.
Was only cleaning up the PUI menubar, not old bindings / names. This led to duplicate bindings, each time the GUI was reset, which can happen for various reasons.
"speed-up" can now also be used for slow-motion (i.e. 0.5 / 0.25 / ...)
or fractional speeds (3.141...). This was already working for instruments
(for replay) before, now it's also considered by FDM simulation.
Allow XML property data to be submitted with a request; changes the request method from GET to POST. Supply nodes via the 'body' argument to the command.
Tolerate Octree leaf children which have been moved outside their leaf's BBox. This is necessary since lazy-loading of ILS and threshold files can cause re-locations even during child traversal, where updating the hierarchy is very complex. Instead, simply tolerate this case, and rely on the real position data (which is correct).
Durk reminded me of this - when we're missing procedures data (the common case), synthesise a plausible (but possibly dangerously unrealistic) departure and approach. Will work fine for airports in gentle terrain, and likely kill you at challenging airports. You have been warned.
When a position is modified for an in-cache FGPositioned, we need to update the runtime information too, or the Octree code may (rightly) complain that it's seeing inconsistent data. Also make the Octree check an exception throw, and verbose, so this is easier to detect in the future.
Don't show invalid AI/MP models in the HUD (after they were removed from
the scene).
Also, when a radar is installed, consider radar/in-range for HUD display.
ASCII protocols consisting of a single chunk only (one variable per line)
would not work when no "separator" was defined.
Also add error message for protocols with more than one var per line which
are missing a separator...
Make landings and takeoffs look more correct; tweak climb-out and touchdown phases in particular, so the turn to destination heading occurs earlier on climb out, and touchdown occurs close the GS transmitter / some distance down the runway from the beginning.
Add missing ATIS elements (transition level, expected approach,
precipitation, runway surface warnings).
Minor phraseology fixes for US/Europe.
Adds "/sim/atis/concise-report" option to use abbreviations (CAVOK etc),
and omit "obvious" units (depends on airport).
Trigger ATIS updates for significant pressure changes.
so we can split ATIS voice files into separate files, i.e. for airport
names and phraseology, so we don't need to regenerate airport names when
extending/changing phraseology. Also allows to add custom airport names.
Enable switching voice files at run-time (different airports could have
different voices...).
puObject only provides float, not double, which causes precision/rounding
issues with some numerical values (try "114.2").
Work around: obtain string value, and manually convert with proper double
precision.
Error/offset induced by precession and yaw also depend on spin (no spin =>
no additional error/offset).
Error/offset induced by changing a/c orientation while gyro spin is
low (<<1) should apply to the "offset" (instead of "error") property.
Expand the performance DB logic to support aliases, and select based on aircraft type as well as class. This allows to introduce some variation into AI traffic performance. Change the initial climb-out waypoints to use pitch-hold until passing 3000', which looks much more convincing
Make traffic manager startup asynchronous, but also avoid frame-stutter due to file parsing on the main thread. Note only XML parsing happens on a thread - once that's complete, everything happens as normal on the main thread, as before.
Apparently most filters are only filtering on type - we weren't running the filter body for navaid or comm-station lookups, causing weird ATIS bugs. Ensure that we actually run the filter at the point we have an FGPositioned* result.
An upcoming commit will make the sound headers standalone, and no longer include various other headers / using std:: declarations. Prepare for this by making includes and usage of namespaces explicit.
Make subsystems create-able and removable from commands. Only some subsystems are supported so far, since many have non-default constructors or other complexities.
With this, change, it's possible to dynamically add and remove the traffic-manager at runtime, for example: fgcommand("add-subsystem", props.Node.new({ "subsystem": "traffic-manager", "name":"traffic-manager", "do-bind-init":1}));
For (future) easier testing of the sim, support a mode where only explicitly named config / option files are loaded, instead of the default ones. (Including, for example, preferences.xml). This currently produces a non-functional sim, but will soon be more useful :)
No behaviour should change unless you try the new option.
FGControls create/init/bind order was incorrect, causing initial property tree state to get over-written. Restructure the code so bind() sees correct values.
- kHz/mHz conversion needs factor 1000 not 100
- Correctly read name for CommStations from NavCache
- Fix parsing CommStation names from apt.dat (Name
can contain spaces)
The Flight-plan leg data computation was omitting certain data for the final waypoint, which in turn made some of the route-manager data bogus when flying the final leg. Fill in some sensible values which we can compute.
Using a tied property works only for one single usage of the
property. In reality FGATIS is normally instantiated four
times (nav/comm/1/2) where only the first instantiation
works correctly. All subsequent instantions fail to tie
and show some error messages.
Also tied properties shouldn't be used anymore.
- Redraw all canvases in the frame OpenVG is initialized.
Otherwise if multiple canvases are created in the same frame
only one of them would get correctly updated.
If OpenVG/ShivaVG is initialized nothing is drawn in the same
frame, therefore we need to draw another frame to ensure all
paths are rendered correctly.
Avoid the application becoming unresponsive during nav-cache rebuilds. We still have to wait for the rebuild, but perform it on a helper thread so the main GUI thread stays responsive and hence doesn't trigger a beach-ball / 'not responding' alert. Also ensures there's some feedback (the spinner) during the rebuild operation, so users don't think we've hung.
In preparation for caching the groundnet in the NavCache, make taxi-nodes and parkings inherit from FGPositioned. As part of this, make them heap (as opposed to value) classes, disable their copy-constructors, remove many mutating operations, and give them real constructors.
New commands request-metar and clear-metar will bind metar reports to an arbitrary property tree path. E.g:
fgcommand("request-metar", var n = props.Node.new({ "path": "/foo/mymetar", "station":"LOWI"}));
- Only render the canvas if something has actually changed
(Currently checked by looking for modified properties).
- Only write bounding box to property tree if it has been
recalculated (until now this happened every frame).
Low spin or switched off gyros result in the indicator being stuck.
When the gyros are repowered, the indication doesn't jump to the correct
indication, but keeps the current error.
so they can instantly adjust to the changed environment.
(Not fully working yet, since some environment settings, like environemnt
pressure/temperature, still changes slowly after a sim reset - instead of
immediately jumping to the new setting. Also, METAR sometimes arrives too
late...).
In advance of converting the Map and NavDisplay to use the canvas, expose the full route-path vector for each flight plan leg, as a vector on the leg. Use leg.path() to get this.
E.g.:
var fp = flightplan();
for (var i=0; i<fp.getPlanSize(); i += 1)
{
var leg = fp.getWP(i);
debug.dump(leg.path());
}
Break some subsystem dependencies, by explicitly using properties to read the primary position, orientation and velocities. (Instead of directly accessing the primary model placement). This means a couple more globals can die.
Keep distro packagers happy by having the option to use the system's sqlite library instead of our bundled version. Set SYSTEM_SQLITE=1 when running cmake to use the system one.
Cache the parsed navigation and airport data in a binary file to reduce
startup times and memory consumption (since only referenced FGPositioned
elements are held in memory).
Data will be reimported when the mod-time of any input file is changed.
If a global file is changed (nav.dat, awy.dat, apt.dat, etc), the cache
will be completely rebuilt, which takes approximately 30 seconds on
moderate hardware. (Future work may reduce this).
Various classes derive from SubsystemGroup, but extend the init behaviour. Fix those for the incremental init scheme, generally by forcing their init to be atomic. Can convert them to be truly incremental in the future if it's needed, but probably not.
Currently if a SGPropertyNode is removed from the property tree
only for this single node a childRemoved event is triggered. So
if we just check for a specific child to be removed, we will never
be notified. This commit manually triggers the event recursively
for all children but this should probably go directly into simgear.
Separate other init functions from position init, since they are unrelated, and made fg_init.cxx very complex. Next step will be brining some sanity to the position init logic :)
(Requires latest SimGear!)
Break fgInitSubsystems into several phases - subsystem creation, then binding and then init. Run init over multiple main-loop iterations so the application stays responsive to GUI/OS events during init.
There should be no behaviour changes due to this, except that during init Windows and OS-X should no longer show the beach ball / 'application not responding feedback', hopefully.
Remove various hacks and make magvar work like a normal subsystem, as part of the environment manager. Fix the remaining users of the globals->get_mag accessor, and hence kill off the global pointer.
Unit is spoken for all values <1000hPa (to avoid confusion with inHg).
Unit is not spoken for values >=1000hPa (but don't drop highest digit).
(And we should replace "millibars" with "hectopascal" - we're missing the
necessary voice sample though.)
- property-interpolate now supports specifying the
interpolation time by passing rate instead of the actual time,
similar to max-rate-of-change in the noise-spike filter.
Something after FG 2.8.0 has broken loading aircraft models from
--fg-aircraft directories. Issue is fixed by resolving the aircraft path
in FGAircraftModel (though this module itself hasn't changed and things
were working before...).
- Groups store property nodes for different styles and pass them
to child elements on creation (No dynamic updates yet)
- Use StyleSetter map instead of loads of if/else if statements
for setting element styles.
- Unify element style properties (Only use one property, instead
of multiple like it has been with colors)
- Fix: Create only one element per property node (Was two)
This might need to be back-ported to 2.8 (to make a 2.8.1), unless it's been exposed by some of my other changes. Which I think is unlikely but not impossible.
so package builders don't need local patches.
Also, instead of hardcoded firefox, use "xdg-open" or "sensible-browser"
launchers on Linux, to auto-detect user's preferred browser.
Override with cmake switch -DWEB_BROWSER=...
(Not affecting Mac/Win which are hard-coded anyway).
- Use bounding box intersections to determine which element is
hit.
- Transform mouse coordinates to local coordinates.
- Try to get osgText bounding box correct (or at least better)
- Refactor and unify common functionality of canvas::Window and
canvas::Image
- Make canvas::Image actually work
- Allow using canvases inside canvas::Image
* Use new canvas:// "protocol" to allow using canvases in
place of images
- Prepare for categorizing canvases:
* Move canvases to /canvas/by-index
* Later support linking to other nodes in subbranches of
/canvas
- Add platform independent clipboard layer for Nasal access
to clipboard (thanks to Hooray for basic code)
- Add Windows clipboard access
- Add partial X11 clipboard access (only reading from clipboard)
- Add fallback clipboard for application internal clipboard if
platform not supported
- Add some helper functions to FGNasalSys
This code is non-functional, but contains most of the stubs to show what's required to add property get/set access, convert to from ghost & C++ types, and manage ownership. Element derived classes & inheritance (e.g., methods on image/path/map elements) will follow, along with some actual functionality!
- Refactor CanvasMgr into PropertyBasedMgr to be also used
for the Canvas GUI system.
- Get rid of tied properties in the Canvas system.
- Add new placement type 'window' for placing canvases onto
windows
- Pass mouse events to Window class (only if cursor is over
window)
- Refactor canvas placement clean up
- Allow hiding objects
- Use UTF-8 encoding for text elements
- Add paramter max-width to text elements
- Support stroke-linecap for path elements
- Fix mouse coords
- Set better mipmap filter
- The new map element automatically transforms geo coordinates
(lat, lon) to the according screen coordinates.
- Currently one type of projection is supported
(Sanson-Flamsteed projection)
