simgear/math/sg_memory.h:
Remove sg_memory.h It is unused anyway and should not be required
in a c++ world. Move distance course functions to the SG* type
system. Move the implementation into SGGeodesy.cxx. Remove some of
the old Point3D Based sg* functions that are already unused.
Remove an extern SGSky *thesky reference that isn't used in the code anyway.
The original code forced a dependency in SimGear back to something that is
defined globaly in FlightGear, not a great strategy for a library with some
"general purpose" intentions.
Maik JUSTUS: workaround for broken Doppler effect in OpenAL
mf: this patch is meant to be removed as soon as OpenAL got fixed. (The
OpenAL developers acknowleged the bug and announced that it'll get
fixed.) For removal try
$ cd simgear/sound
$ cvs diff -rAFTER_OPENAL_DOPPLER_WORKAROUND -rBEFORE_OPENAL_DOPPLER_WORKAROUND|patch
Maik JUSTUS: Doppler fixes (add option to turn off Doppler for sounds that
shouldn't be affected -- marker beep, ATIS messages, etc.)
mf: this is the first part of the original patch. It is supposed to contain
fixes that are not caused by OpenAL bugs, and thus aren't meant to be
reverted later. The second part will contain a temprary workaround for
OpenAL bugs. Unfortunately, I had to do the split myself as the contributor
refused to do it.
- close loophole through which one could sneak in illegal property names
containing slashes, colons and all sorts of evil characters. In Nasal
this could be done via props.globals.getChild("1!@#$//[]{}", 0, 1).setValue(0);
The cause is that getChild() hands the given name directly over to an
alternative SGPropertyNode ("convenience") constructor which sets the
name without any checks.
- unify exception messages: first character is lower case
replace exit() by throw sg_exception(). Of course, we have to be aware
that interdependencies between sg libs are generally unwelcome, but
sg_exception is a rather basic part, and it's already used by xml, props,
scene, sound and, of course, structure. Since props and xml are core
libs, we can assume that sg_exceptions are available. (OK'ed by Curt)
add SG_ORIGIN macro that expands to a string __FILE__":"__LINE__
Note that __LINE__ is a number and can't be directly used in string
context, which makes the macro worthwhile. (IMHO :-)

advance tracing messages from SG_INFO to SG_ALERT. If a developer has
demanded tracing, then he shouldn't get these important messages buried
in thousands of lines of meaningless bulk.

Sync with Nasal upstream. Mostly fixes to naContinue(), which
FlightGear doesn't use. Also includes a performance fix for the
call() builtin that should help Melchior, who was measuring lower
performance for the props.Node() interface than the getprop/setprop
API.

Add method to return the number of attached listeners. Listeners have become
a much more important feature than they were two years or something ago, and
it's helpful for debugging and exploration to get this important node property
shown in property tree dumps or in the property browser (verbose mode).

- fix bug where a property tree saved with writeProperties() and read back
in with readProperties() would not look the same, because element indices
of '0' were even dropped when a node has a "secret" value *and* children
- introduce "omit-node" modifier attribute for the "include" attribute.
This inserts the given file in place of the including node, while the
node is dropped. This is desirable for multiple includes (which can't
be done by multiply using the "include" attribute, as this isn't valid
XML spec syntax)

Use __FUNCTION__, which works on gcc and MSVC 7/8, instead of
__func__, which while standardized works only with gcc. I'll wait for
bug reports from VC6 before bothering with fallback code...

Melchior points out that NaN/Inf behavior is not platform-independent.
So toss a runtime error ("floating point error") when any of the math
library functions produce a non-finite value. Note that these are not
the only locations that can do that (simply dividing by zero will
produce an Inf), but it's still proper behavior.

Sync with Nasal CVS (soon to become Nasal 1.1). Notable new features:
Nasal now supports calls to "subcontexts" and errors can be thrown
across them, leading to complete stack traces when call() is used,
instead of the truncated ones we now see.
Vectors can now be concatenated using the ~ operator that used to work
only for strings.
Better runtime error messages in general due to a fancier
naRuntimeError() implementation
A big data size shrink on 64 bit systems; the size of a naRef dropped
by a factor of two.
"Braceless code blocks" have been added to the parser, so you can
write expressions like "if(a) b();" just like in C. Note that there's
still a parser bug in there that fails when you nest a braced block
within a braceless one.
Character constants that appear in Nasal source code can now be
literal multibyte UTF8 characters (this was always supported for
string literals, but character constants were forced to be a single
byte).
New modules: "bits", "thread", "utf8" and (gulp...) "io". The bits
library might be useful to FlightGear, the utf8 one probably not as
Plib does not support wide character text rendering. The thread
library will work fine for spawning threads to do Nasal stuff, but
obviously contact with the rest of FlightGear must be
hand-synchronized as FlightGear isn't threadsafe. The io library is
no doubt the most useful, as it exposes all the basic stdio.h
facilities; it's also frighteningly dangerous when combined with
networked code...
