Fix for weather interpolation problem from Anders Gidenstam
Anders said:
With Stuart's help I've looked closer at this and I think I've tracked
down the cause of the problem:
At least on my computer the sort() call on line 234 in
Environment/environment_ctrl.cxx sorts the vector entries by memory
address instead of altitude, i.e. the custom comparison predicate is not
used. This causes the tables of environment conditions to be reordered
into a wrong order at some weather updates, depending, basically,
on where the memory allocator places the objects. (Btw. why are they are
freshly allocated for each update?)

- Ground network XML parsing code reads the new attributes "holdPointType"
and "isOnRunway".
- Added initial support for AI controlled pushback operations, making use of the
current editing capabilities of TaxiDraw CVS / New_GUI_CODE. The current
implementation is slightly more computationally intensive than strictly
required, due to the currently inability of taxidraw to link one specific
pushBack point to to a particular startup location. FlightGear now determines
this dynamically, and once we have that functionality in TaxiDraw, the
initialization part of createPushBack() can be further simplified.
- Smoother transition from pushback to taxi. No more skipping of waypoints, and
aircraft wait for two minutes at pushback point.
- The classes FGTaxiNode, FGTaxiSegment, and FGParking, now have copy
constructors, and assignment operators.
- Removed declaration of undefined constructor FGTaxiNode(double, double, int)
- Array boundry checks and cleanup.
- Modified Dijkstra path search algoritm to solve partial problems. Currently
limited to include pushback points and routes only, but can probably be
extended to a more general approach.
- Added initial support for giving certain routes in the network a penalty, in
order to discourage the use of certain routes over others.

Stuart BUCHANAN:
"interpolates METAR changes over time as follows:
1) Wind changes are interpolated as vectors, so the change is much more
natural than before - no-longer will your aircraft be suddenly shoved to
one side.
2) Visibility is interpolated as an X-value, which looks pretty neat.
3) Cloud heights and thicknesses are interpolated if they are close to the
aircraft. Cloud textures are not."
generic/output:
- support optional <preamble> and <postamble> which are written right
after opening and before closing respectively. This can be used for a header
line or an XML header.
- unescape <preamble>, <postamble>, <format>, <line_separator>, <var_separator>
so that \t, \n, \r, \f, \v, \xnn, \nnn can be used directly (\a and \b are
ignored; use \\ for the backslash) The long names ("carriagereturn") are still
supported for <var_separator>, but one can just use \r, or \r\n too.
- don't abort when a chunk doesn't have a <node>. This is useful for adding
constant chunks which consist only of a <format>, such as XML tags.

Remove obviously unused variables from FGInterface, make use of
SGMath functions. No longer use plib math functions in FGInterface.
- Added ultra-light traffic is now a separate traffic class that can have its
own preferential runway support. In future versions, we might want to
condider having a more generic mechanism for this.
- Keep a history of active runway for each class, so that runway assignments
are more consistent after whether updates or time-related schedule changes.
Martin Spott:
On most Unix platforms like FreeBSD, Solaris, IRIX (AIX is even worse)
- just not on Linux - the linker wants to know about _all_ required
libraries. So even if a shared library "libosgViewer" itself is linked
against "libosgGA" and "libosgText", you still have to name these in
order to build an "fgfs" binary.
Currently, other libraries like "-losgDB" and "-losgUtil" are
explicitly mentioned on the "fgfs" linker command, but "-losgGA" and
"-losgText" are not. This simple patch lets the linker honour
everything that's required
First revision of a small utility that will build a simple .ac file around
a aerial photo texture. You need to determine the coordinates of the 4
corners of your image and this utility will use that to build a 3d model
in meters and tell you the information to copy into the proper .stg file.

- set namespace __kbd for all keyboard Nasal code (not meant for public use)

Bugfixes: 1) Fix the if (next) setLeadDistance bug
(reported by Csaba Halaszi /helijah)
2) Decrease AI aircraft Heading error tolerance to 1% of its
original value. This is necessary to mitigate spinning and
makes for actual "on-runway" landings.

I refactored the XML loading code out of FGAirportDynamics and
FGRunwayPreference. I also added a new class XMLLoader, which serves as a

solution than storing the airport data a second time ;-)

allow to specify a node type: --prop:[type:]name=value
where type is one of string (default), double, float, long, int, bool
Using only the first letter works, too.
--prop:foo=123 ... sets property foo to string 123 (old behavior)
--prop:string:foo=123 ... verbose version of above
--prop:s:foo=123 ... slightly less verbose version of above
--prop:bool:foo=1 ... makes property a bool of value 'true'
I hope this isn't considered a silly gimmick. I need this often and maybe
other developers do, too. It's useful in cases where the difference really
matters. if (getprop("/foo")), for instance, is TRUE even when the property
contains string "false", as all strings are TRUE.

Durk Talsma: Added the detection of "circular" wait situations in the AI

b; b waits for c; and c (in turn) waits for a. The checkCircularWaits

The current "solution" to a circular wait is rather crude: Remove the
aircraft from the scene. A proper solution needs a lot more work, however,
and at least this patch stops the AI system from clogging up. in case of a
