since "next" is already frozen for 2.8 and is prepared for building the
first release candidate.
For details on versions see http://wiki.flightgear.org/Release_plan
Status message are almost invisible - use warning message instead, so
builders/packagers actually notice a missing dependency.
Also add some useful hints.
Fixes the "weirdness" with MSVC complaining about incomplete class specs,
since forward declarations (SGMathFwd.hxx) are used in props.hxx only.
Only the few extended (vector) property templates require including the
full SGMath.hxx (with MSVC) - and these are used in few places.
References in simgear's cache maps prevented effects, textures, clouds,
trees and lights from being unloaded at run-time (ref-counter could never
reach 0). Changed cache maps to use OSG 'observer' pointers instead, so
reference counters aren't influenced, though cache maps still hold an
(observing) pointer. Also take care when finding a cache entry with empty
content (i.e. texture was unloaded).
Always check the return value of "findDataFile". If it's empty, always
provide the _original_ path being searched in an error message. Otherwise
we eventually just get useless 'Can't find file "".' error messages
(and also a segfault here, since osgDB::readImageFile("") returns NULL).
Only worked when TMPDIR environment variable had a trailing slash (i.e.
"/tmp/" worked, but not "/tmp").
(Problem shown by simgear's "test suite". It's good to have tests!)
Fixes the more basic probelm of "SGModelLib::findDataFile" resolving an
empty file name to the fgdata (directory) path. findData_File_ should
never return a _directory_ path, only valid _file_ names.
Don't resolve the empty file name, which would result in the fgdata
directory path (instead of a path to a file). Eventually this resulted in
a segfault, partly due to a bug in "osgDB::readImageFile", which reports
"success" when given a directory (instead of a file) path, though it
doesn't return a valid image object.
Cut trailing separators when converting from string to sgpath.
Also, SGPath::fix does NOT replace ":". It only replaces "\" with "/",
so the "i!=1" check for Windows made no sense (rule #9: never believe
a source code comment).
Sound resources were eaten up when a sample could not be loaded.
Restores sound for aircraft attempting to use stereo files for sound effects.
However, when loading fails, sound code still tries to load the same file
again and again (always resulting in the same "stereo files not supported"
error), which slows down simulation.
Determine name of library installation directory, i.e. "lib" vs "lib64",
which differs between all Debian-based vs all other Linux distros.
See cmake bug #11964, http://cmake.org/gitweb?p=cmake.git;a=commit;h=126c993d
Also provide a script for older (<=2.8.4) cmake
Keep Nasal parser from crashing when "=" function misses a left-hand
element, i.e. when parsing "sin(=)".
(Or do people writing such terrible syntax deserve a crash? ;-) ).
Use standard path resolver when searching for includes. Includes like
<foo include="/Aircraft/Instruments/myfile.xml">
are now also supported - no need for
<foo include="../../../Aircraft/Instruments/myfile.xml">.
File dialogs never showed ".." directories for navigation, since these were
filtered by the "INCLUDE_HIDDEN" option. Only the "NO_DOT_OR_DOTDOT"
option should be used for filtering - otherwise it's impossible to show
the "."/".." directories while all other files are still hidden.
Added missing CMake defines for SVN_CLIENT.
Don't detect libsvn without APR.
When installed, enable libsvn support by default (same as for automake).
When enabled, provide libsvn include dir to libtsync.
gitignore temporary CMake files
Changing and reverting the locale isn't thread-safe. Instead, setup the
environment to ensure the active locale sticks to default "C" locale at
any time.
Whenever resolving a (relative) path to an absolute path with
'findDataFile', check if the result is empty and report original
(relative) path as missing. Otherwise no or a meaningless message is
issued ("File '' not found.").
Ignore errors due to missing (ocean-)scenery data on SVN server.
For now, only refresh scenery tiles when ocean is replaced by actual
scenery data after download.
