When the test:
if (i == activeTraffic.end() || (activeTraffic.empty()))
was true, the iterator named 'current' was uninitialized and later
dereferenced.
Fix:
- when the previously-mentioned test is true, return;
- initialize 'current' only when it is really needed (i.e., later and
after the test), and since we don't need it for iterating, make it
an FGTrafficRecord&.
This change is the logical counterpart of SimGear's change from commit
79f869a7f32910197be72b21f6489fbbba02c836 that moved the following files
from simgear/misc to simgear/io/iostreams:
gzcontainerfile.cxx
gzcontainerfile.hxx
gzfstream.cxx (formerly zfstream.cxx)
gzfstream.hxx (formerly zfstream.hxx)
sgstream.cxx
sgstream.hxx
sgstream_test.cxx
When using live weather fetch, the QNH should be obtained from
environment/metar/pressure-inhg.
See: http://sourceforge.net/p/flightgear/mailman/message/35037125
Add new method getQnhInHg to ATISInformationProvider and its implementations
to avoid rounding errors converting from hPa back to inches in ATIS reports.
The CurrentWeatherATISInformationProvider (used when live weather fetch is
not in use) continues to use the property environment/pressure-sea-level-inhg.
This produces the incorrect QNH at airports significantly above sea level
but this needs fixing elsewhere to calculate the correct QNH.
- Add section tag to support inclusion of ATIS fragments.
- Add visibility, QNH and cloud tokens to support new ATIS formats.
- Add support for starts-with, ends-with and contains comparisons in
conditionals, including negated versions.
- Strip and convert case in comparisons.
- Speak VRB wind direction as "variable".
- Speak zeroes in fractional part of QNH inHg.
- Force US voice in US, Canada and Pacific; UK voice in UK.
Prior to this change, it was only possible to compare the values of tokens
to each other for use in conditionals, e.g. landing and departing runway.
This change allows comparison of a token to a text value, e.g. to compare
wind speed to zero.
This patch may introduce an occasional crash on exit again, because it effectively undoes commit [a972df]. I'll try to find a better fix for that later on.
- when dynamics shuts down the ATC controllers, they clear their
traffic vectors (destroying the records), but we didn’t notify
the AI aircraft of this. Ensure the controller is cleared so
the AI aircraft shutdown doesn’t crash.
- remove some global headers from AI headers, to avoid pollution
- change how ATC owns the ‘player’ FGAIAircraft so reset works
- ensure AIAircraft controllers are cleared on unbind for reset
- ATC functions move to GroundController, which layers above
remaining GroundNetwork functionality
- dynamics owns both the groundNetwork and the ground controller.
Added the fallback for realweather fetch disabled, creating
ATIS from present weather
Fixed some formatting errors, mainly missing spaces
Some code cleanup
Ensure all FGPositioned related functions return SGSharedPtr
instead of raw pointers to allow automatic conversion to
nasal ghosts without custom helper functions.
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
- 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)
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.
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).
* Pregenerating taxiroutes could interfere with runway assignments by ATC, when conditions changed, resulting in a taxi to one runway and a takeoff from another
* A simpler solution for the "Error in Traffic record bug". This still needs some more testing, but I haven't seen any error message anymore, since changing to the current code.
* Initialize AI traffic at speed zero, this should prevent some weirdness observed under boundary conditions.
* Don't activate groundnetwork proximity detection for pushback traffic until the "ready for startup message is transmitted. this should allow sufficient time for them to reserve a route, but a little more testing still needs to be done.
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.
* Improved groundnetwork routing algorithm. Don't uncesscarily block taxiways. Instead, use a "just-in-time" blocking system. The unblocking algorithm still needs some work, but the current version is already a major improvement over the previous version.
* Some tweaks to the handover from ground to tower controller. Aircraft could refuse to take-off of even refuse to taxi onto the runway. This now seems to be solved.
* Landing AIAircraft now land properly!!!
* Fixed problems with takeoff scheduling.
* Untangled several vertical speed calculation algorithms.
* No more bent-over-backwards and jump-in-the-air AI aircraft initializations.
* Fixed intermixed target speed and target altitude during climb phase.
* Implemented beginnings of a "line up and wait" procedure.
* Tried to use actual runway elevation for calculating the decent profile.
