Make a single Cmake value to expose the build type to code, and use
this to default a run-time ‘developer-mode’ property, which can be
over-ridden from the command line.
Use this to drive the different warning levels. Policies subject to
review, especially whether nightly builds should default to
developer mode or not.
Uses TTF fonts, and displays more information textually including
the application version and current aircraft.
Also rename FGRenderer::splashinit to preinit, as was suggested
a long time ago.
Each argument creates another log file, in the directory named. Symbolic
value ‘desktop’ creates logs on the user’s desktop.
Needs corresponding SimGear commit to build
- Add an optional argument to flightgear::initApp(): doInitQSettings.
This argument defaults to true, preserving initApp()'s behavior in
this respect. If this argument is set to false, FGGlobals doesn't have
to be initialized.
- New function flightgear::initQSettings(), called by
flightgear::initApp() when its 'doInitQSettings' argument is true.
This allows initializing the QSettings exactly when it is needed.
- New function flightgear::checkKeyboardModifiersForSettingFGRoot().
The code it contains used to be run from initApp(), which is
undesirable because:
1) initApp() is not only called at FG initialization (fgMainInit()),
but also from QtMessageBox(), from QtFileDialog::exec() and twice
from Options::setupRoot(). However, checking the Alt and Shift
modifiers to set 'fg-root' in QSettings to the special value
"!ask" only makes sense in fgMainInit(), not in these other
places.
2) This code relies on the QSettings to be set up, and therefore on
FGGlobals. Thus, freeing initApp() of its dependency on FGGlobals
requires splitting this keyboard modifiers checking code out of
initApp().
Apart from providing a public method giving a path to the autosave file,
the main idea of this commit is to reduce redundancy where
globals->get_fg_home() was so far used in every place where the autosave
file is needed or saved. Use an optional argument for
FGGlobals::loadUserSettings() and FGGlobals::saveUserSettings()[1],
since it should be exceptional to access an autosave file in another
location than $FG_HOME.
Also add comments explaining how to avoid security pitfalls with
saveUserSettings() (cf. discussion around
<https://sourceforge.net/p/flightgear/mailman/message/35461636/>).
[1] Argument *added* to this method, for consistency with
FGGlobals::loadUserSettings().
With Simgear commit d7d59b08a2f1a77a4247ec1a89d6ff48ed73f5c7, this
allows terrasync to be initialised from files in the install data,
which avoids downloading them again.
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.
When set on the command line, will be used for aircraft packages. When
set in the Qt launcher, will also be used for aircraft downloads at
all times.
When changing the path in the launcher, the set of aircraft catalogs
is refresh automatically. Note the default catalog may need to be
re-installed.
While mostly harmless since you're exiting anyway, it's an annoying
distraction when the real problem is "unexpected exit" (e.g.
https://bugs.debian.org/763285 ), and blocks testing with LeakSanitizer
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.
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.
- 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).
- 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.
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)
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!)
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.
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}));
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.
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).
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.
Don't initialize the offset in the main loop but in
the init method of the implementing class. This ensures
it gets initialized if you instantiate more than one
heading-indicator and does not initialize the property for
unsused heading-indicators (no more stray heading-indicator-fg
property anymore).
