The current code still has some rough edges, in particular memory still
needs to be deallocated where possible, and the actual use of the code
needs more testing. This code has been running without noticable problems,
so I think it's ready for some wider exposure. Detailed changes include:
- Finetuning of the SID/STAR data concept.
- Preloading of all SIDs, from one xml file.
- ATC determines which SID should be used and echoes this over the com1 or
com2 radio.
experimental: Only one SID per runway is supported, and the waypoints are
read from file at every request, which is not very efficient. The current
code is only executed when FlightGear is configured to use airport dynamics
data from the scenery repository, instead of the base package. Since the
latter is still the default, I believe that this will provide enough safe-
guarding to commit SID/STAR support in small, incremental steps.
Next step will be buffering and support for multiple departure routes per
runway.
* Changed the runway XX. ATC message to actually report the real
designated departure runway
* In case of multiple active runways, select the one with a heading that is
closest to the direction of the ultimate departure destination / lines up
with the arrival path.
* Some support for geometry information provided by the custom scenery
project. Current support is for AI groundnets and runway use files only
since this is a switch that involves a lot of data verification and
updating, during the transistion the actual path where the data can be
read from is user configurable. setting the property
/sim/traffic-manager/use-custom-scenery-data to true
will cause flightgear to read the ground networks from the scenery
directory (--{fg-scenery}/Airports/[I]/[C]/[A]/[ICAO].groundnet.xml to be
precise). Setting this property to false will retain the original
behvior.
* For departing aircraft, runway takeoff calculations will be done on the
basis of the performance database. For testing purposes, a performance
estimate for a heavy jet has been added.
notion of a 'displacedThreshold'. Now there's just a real threshold,
displaced or otherwise, and people who care about the paved area can use
'begin' and 'end'. Thanks to John Denker for pointing out the confusion this
leads to. Using 'end' also gets rid of the 'reverseThreshold' name, which was
clearly a bad choice of mine.
This patch changes terrasync so it links against the subversion
library if you have it installed. It supports people who build binary
releases for use by non-developers by removing the runtime external
dependency on having command line svn or rsync available. Since the
patch changes autoconf to detect libsvn, I'd appreciate it if people
who release binaries could verify that the detection scripting works
for their platform.
Developer warning: If you do have libsvn developer libraries
installed, terrasync changes its default option from "-R" to "-S" to
remove the command line dependency. However, Martin has not yet
uploaded world scenery into the subversion repository so it won't be
useful to fly against and you may want to specify "-R" on the command
line in the short term. Or run both.
Me: Update MSVC 7.1 project file. Need svn-win32-1.x.y_dev.zip and svn-win32-1.x.y.zip

Convert FGRunway to be heap-based, and inherit FGPositioned. This is a large, ugly change, since FGRunway was essentially a plain struct, with no accessors or abstraction. This change adds various helpers and accessors to FGRunway, but doesn't change many places to use them - that will be a follow up series of patches. It's still a large patch, but outside of FGAirport and FGRunway, mostly mechanical search-and-replace.
An interesting part of this change is that reciprocal runways now exist as independent objects, rather than being created on the fly by the search methods. This simplifies some pieces of code that search for and iterate runways. For users who only want one 'end' of a runway, the new 'isReciprocal' predicate allows them to ignore the 'other' end. Current the only user of this is the 'ground-radar' ATC feature. If we had data on which runways are truly 'single-ended', it would now be trivial to use this in the airport loader to *not* create the reciprocal.
- removes various members from FGRunway which no-one was using
- any of these can be trivially re-instated if and when someone
actually wants to use them - but right now they're simply bloating up
FGRunway, which we have lots of, because it currently includes all the
taxiways in Robin's data.
- that's it.
- Runways are now part of an airport, instead of a separate list
- Runways are no longer represented as a boring struct, but as a class
of their own.
-Improved runway access to unify various runway access methods.
- this exposed a bizarre issue on Mac where dragging in <AGL/agl.h> in
extensions.hxx was pulling in all of Carbon to the global namespace
- very scary. As a result, I now need to explicitly include CoreFoundation
in fg_init.cxx.
- change SG_USING_STD(x) to using std::x
SimGear change. It changes all the SG_xxxx to be the 'real' includes, and gets
rid of many #ifdef SG_HAVE_STD_INCLUDES. As an added bonus, rather than
replacing 'SG_USING_NAMESPACE(std)' with 'using namespace std', I just fixed
the small number of places to use std:: explicitly. So we're no longer polluting
the global namespace with the entire contents of std, in many cases.
There is one more 'mechanical' change to come - getting rid of SG_USING_STD(X),
but I want to keep that separate from everything else. (There's another
mechnical change, replacing <math.h> with <cmath> and so on *everywhere*, but
one step at a time)
