Similar to the existing FGGlobals::get/set_terrasync_dir(), add
FGGlobals::get_download_dir() and FGGlobals::set_download_dir() methods,
and of course the corresponding FGGlobals::download_dir public member
variable. FGGlobals::set_download_dir() stores the realpath() of the
given directory, including into the /sim/paths/download-dir property,
which is marked as read-only just as /sim/terrasync/scenery-dir already
is.
Handle the setup of the TerraSync and download dirs all in the same
place (Options::processOptions()), since most of the work is already
done there. This allows one to get rid of fgOptTerrasyncDir() and
fgOptDownloadDir(), and to make it easier to see that
globals->set_terrasync_dir() (resp. globals->set_download_dir()) is
called on the correct SGPath, regardless of whether --terrasync-dir
(resp. --download-dir) was passed.
Always create the TerraSync and download dirs when they don't already
exist, regardless of whether --terrasync-dir or --download-dir has been
given on the command line.
Add comments explaining how to avoid security pitfalls with download and
TerraSync dirs (cf. discussion around
<https://sourceforge.net/p/flightgear/mailman/message/35461636/>).
Adjust indentation where it was too broken, hampering readbility.
1) Paths and the FG_SCENERY paths list are now printed like:
FG_ROOT=/home/flo/flightgear/src/fgdata
instead of:
FG_ROOT=Path "/home/flo/flightgear/src/fgdata"
Moreover, FG_SCENERY is now correctly printed (without 'Path ""'
wrapping, without Terrain, Objects and markers instead of the actual
scenery paths) regardless of the position of --version relatively to
--fg-scenery, --terrasync-dir, etc. Of course, the values given to
these options do influence the output of --version.
Simplify printing of FG_SCENERY via SGPath::join() and use the
correct, OS-dependent separator between paths, SGPath::pathListSep.
Write the --version output to stdout, as already done for --help;
then it can be easily piped to $PAGER and doesn't get mixed with the
output of SG_LOG (which is on stderr). This is of course backward
incompatible for programs reading the stderr output of
'fgfs --version', but has been agreed upon on FlightGear-devel (cf.
<https://sourceforge.net/p/flightgear/mailman/message/35461619/>).
2) Don't write explicit values in the OptionResult enum: they don't
matter, but giving them is error-prone in case one does a copy-paste
to add a new member to the enum and forgets to change the value.
Expand existing —-config option to read either property-XML files (as
it previously did) but for non-XML files, to parse them as command
line argument files.
Remove uses of .str(), .c_str() and some other methods of SGPath.
Pass SGPath directly where possible, or explicitly convert to the
appropriate 8-bit encoding.
The --metar option has no effect unless --disable-real-weather-fetch is
also passed. This often makes users believe that --metar doesn't work.
Change the implementation for --metar so that it automatically implies
--disable-real-weather-fetch.
- add a button to the main dialog, explaining how to adjust the
fg-root path via the GUI
- tweak the GUI flow to support explicitly changing the path even
when the default path is acceptable.
* Before setting /sim/aircraft-dir from the --aircraft-dir option,
canonicalize its value with SGPath::realpath() as is already done in
FGGlobals::append_aircraft_path() for the paths given with --fg-aircraft
or via the FG_AIRCRAFT environment variable.
* This fixes a bug when --aircraft-dir is used, due to the fact that
fgValidatePath() canonicalizes its 'path' argument before matching it
against the allowed patterns, and therefore will not validate paths
under the directory specified with --aircraft-dir if this directory has
been given in a non-canonical form by the user (e.g., containing at
least one symlink component).
* This fix does not lower security: the path which is canonicalized has
been explicitely given by the user. This operation is already done for
all paths specified with --fg-aircraft or via the FG_AIRCRAFT
environment variable, via Options::initPaths() which calls
FGGlobals::append_aircraft_paths().
* To reproduce the bug, create a symlink (e.g., /tmp/aircrafts) to a
directory suitable for --fg-aircraft, then run:
fgfs ... --fg-aircraft=/tmp/aircrafts \
--aircraft-dir=/tmp/aircrafts/SenecaII --aircraft=SenecaII
This will trigger many failures such as:
loadxml: reading '/tmp/aircrafts/SenecaII/Dialogs/registration.xml'
denied (unauthorized directory - authorization no longer follows
symlinks; to authorize reading additional directories, add them to
--fg-aircraft)
(from do_load_xml_to_proptree() in flightgear/src/Main/fg_commands.cxx)
I have also tested this with the ec130b4 and the 777-200ER. Same
problem, same fix.
The old Mac launcher doesn’t work on Yosemite, add a tiny
Qt-based launcher inside the main process (no need to fork /
exec) which runs before the OSG window is created.
Will be merged for 3.4, hopefully with no impact on other
platforms.
Adds new option --load-tape=foobar to load a flight recorder
tape from the command line. Loads foobar.fgtape from the
directory specified in /sim/replay/tape-directory and starts
replay.
- /sim/aircraft can be set to package ID, including qualified
package ID. If not matching package is found, falls back to
traditional search of fg-aircraft for -set.xml files
Fixes confusing startup behaviour with malformed args, when
an argument accidentally contains a space (e.g. a park-pos or
protocol desc). In this case we treat the parts after the space as an XML config file name. When we can't find this file, we
completely abandon options setup, which causes many downstream
errors.
Change the behaviour so we warn in this case, but carry on with normal startup.
* make --enable-fpe work on Linux and MSVC
* standardise the code paths for different platforms
* add an argument finding helper to Options
(This is a basic cleanup, contributions from people with
more experience in this area are welcome)
- no dependency on libJpeg or Simgear
- no duplicate rendering of the scene (uses a draw callback)
- supports other image types, eg PNG
- threaded so doesn't block the main loop ever
This makes the behaviour when FGRun (or other GUI launchers)
send bad options much more explicable. Non Windows/Mac systems
get an SG_ALERT on the console as before.
This was previously done only if Terrasync was on, but this made
it impossible to use the GUI dialog to turn it on for the first
time in a fresh install
Write PID file to FG_HOME, use this to detect multiple launches.
When this situation is detected, set a marker property and place various
objects into read-only mode, such as the NavCache and TerraSync.
PID file is created using open+unlink semantics on POSIX, and
DELETE_ON_CLOSE on Windows, so it will be removed when fgfs exits,
even if killed or crashes.
This allows us to display a platform-native dialog for problems
which occur early in startup (before we can show a PUI/Canvas dialog).
In particular this improves feedback where FG_HOME, FG_DATA or
aircraft selection is wrong, all of which happen very early in startup.
Requesting 16-bit is probably doing more harm than good on modern
hardware. Command line switch to change works as before.
Also update the default window size, although this is actually
set by preferences.xml
- default to SUBSYSTEM:WINDOWS (we can still AllocConsole if needed)
- add --console option to get a console on Windows
- ensure --show-aircraft and --help modes show the console automatically.
- restore-defaults kills the nav cache, terra-sync cache
- new ignore-autosave option bypasses autosave.xml and leaves it
untouched (does not over-write on exit)
Replace many lingering calls to exit() from the code,
replacing most with exception throws, which can be
caught by the existing mechanisms.
Update the option-parsing code to return an explicit
value indicating what to do (e.g., exit status to return
to the shell).
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"
- 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.
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.
"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.
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.
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).
- move property /sim/auto-coordination to
/controls/flight/auto-coordination
- introduce new property /controls/flight/auto-coordination-factor
with default of 0.5
- auto-coordinate the rudder if auto-coordination is true and the factor
is greater than zero
backward compatibility for the old property is temporary provided by
a temporary Nasal hack in FGDATA/Nasal/aircraft.nas
Replace SG_GENERAL by more specific log classes in many places.
Allow "," to separate logging classes (using "|" is odd on the
command-line).
Also add new option to make logging more useful for developers.
You can use:
--log-level=debug --log-class=environment
to only get environment debug messages, or
--log-level=debug --log-class=sound,ai
to only get debug messages related to the sound or AI subsystem.
Add range checks and provide error messages.
Extend time offset to 64bit - so we're safe for 2038-01-19 (and the next
couple of millions years beyond...).
Support partial date/time strings, such as --start-date-gmt=2011 or
--start-date-gmt=:::12:00:00
This fixes at least the startup process.
If an ambigous fix name was presented with --vor=ID or --ndb=ID
present a list of matching records along with frequency and
position in the console to give the user the chance to pick
the correct one by adding the frequency with --vor-frequency=nnn.nn
It does not yes solve the issue when the user relocates using the
GUI dialog. This requires some GUI and Nasal hacking along with a
new Nasal helper function "navaidinfo".
--ai-scenario=... can only add/enable another scenario.
Introduce --disable-ai-scenarios option to disable all scenarios (can be
used by external launchers, GUIs etc)
Also provide error instead of debug message when a scenario cannot be loaded.
New module contributed: AV400WSim.
Supports communication with external (aka real) Garmin 400/500 WAAS flight
sim units. Includes changes to options.cxx and fg_io.cxx to support
invoking and configuring the new module.
make options
--wind=nnn@mm
--visibility
--visibility-miles
--ceiling
--turbulence
work again. These options now write properties in the
/environment/config/presets
branch. The values will be applied in the property-rules
in FGDATA/Environment/interpolator.xml
- #248: new enable/disable-ai-traffic command-line option
- AI traffic: don't wait for METAR when real-wx-fetch disabled, to
enable AI traffic when running offline
This is the initial commit for a reworked environment controller.
The main intention is to decouple the individual modules like
metar fetch, metar properties, environment interpolation etc.
to make it easier for other weather module developers to modify
environment settings.
As a side effect, the dialogs for weather-scenario, weather-conditions,
clouds and precipitations have been merged into a single dialog
Add helper to look for an aircraft branch path in multiple candidate locations.
Update the main subsystems to use the helper, and hence load from any aircraft dir.
