Since the new _storagePath data member internally contains the add-on
id, changing _id after _storagePath has been initialized would make both
data members inconsistent. As changing the add-on id is probably not a
very useful operation, the simplest way to prevent such an inconsistency
from happening is to make Addon's _id data member const (as is already
the case for _storagePath), and thus remove Addon::setId().
Consequently, remove the Addon default constructor too, since add-ons
with an empty id would be ill-formed and couldn't be changed (_id being
const now). This leaves us with one Addon constructor:
Addon(std::string id, AddonVersion version = AddonVersion(),
SGPath basePath = SGPath(), std::string minFGVersionRequired = "",
std::string maxFGVersionRequired = "",
SGPropertyNode* addonNode = nullptr);
New methods Addon::createStorageDir() and Addon::getStoragePath() with
corresponding Nasal bindings in the addons.Addon ghost:
createStorageDir() method (returns the dir, doesn't fail if it already
exists)
storagePath read-only attribute to get the dir
The directory reserved for each add-on is
$FG_HOME/Export/Addons/ADDON_ID, but please use the above methods (or
the corresponding C++ ones) to avoid hardcoding such paths in your code.
Also create directory $FG_HOME/Export/Addons in fgInitConfig() as a way
of reserving the namespace, in order to prevent future failures in case
someone would have the strange idea to create it as a file...
It is the call to exit that causes FG to lock up and become a zombie.
Alternative is to throw an exception, i.e.:
throw sg_error(std::string("YASim SOLUTION FAILURE:") + a->getFailureMsg(););
This adds the fix for non converging aircraft. Henning has performed a thorough analysis of all of FGAddon and other repositories and there are a few models that fail, however there have always been a few that fail - but with this patch this situation is improving.
As for aircraft, an add-on can now add its custom dialogs in
$addon_dir/gui/dialogs. This commit makes NewGUI consider this directory
as a dialog-providing one for each registered add-on.
If an add-on has a file named addon-menubar-items.xml in its base
directory, load it and add its items to the FG menubar.
Logically, fgStartNewReset() should call
flightgear::addons::AddonManager::instance()->addAddonMenusToFGMenubar()
in order to re-add the items, however doing so would cause the
add-on-specific menus to be added one more time on every reset, because
for some reason, commit 45ea8b5daa added
the PRESERVE attribute to /sim/menubar (apparently to preserve the state
of menu entries upon reset?).
Note: the addon-menubar-items.xml files are reloaded during reset,
however the menu bar doesn't reflect this, since adding the
reloaded items to the menu bar in fgStartNewReset() would cause
the add-on-specific menus to appear several times in the menu bar,
as explained above.
Preparation for work on the synchronisation and lag prediction filters that jano has underway - firstly by adding a property to indicate the mode of the clock being used. Pre 2018.1 will be mode 0.
Automatic selection in the launcher is disabled for now, since
it needs more testing before release, but the basic UI for selection
is straightforward enough to throw in.
The add-on framework now uses the following files in each add-on
directory:
- addon-config.xml (previously: config.xml)
- addon-main.nas (previously: main.nas)
This is consistent with the addon-metadata.xml file that is already part
of the interface between FG core and add-ons. The goal is to make it
clearer, when browsing an add-on directory, which files belong to the
"FG core <-> add-on" interface and which files belong to the add-on
proper. This will be beneficial also when more files are added to the
"FG core <-> add-on" interface, such as possibly addon-events.xml in the
future.
This change is incompatible, thus it is the right time to do *before*
2018.2.1 is out, especially considering that this upcoming release
already has incompatible changes in the add-on API, namely the
requirement of the addon-metadata.xml file and the type of the argument
passed to each add-on's main() function. We'll try harder not to break
compatibility in the add-on API once 2018.2.1 is out. For now, it is
still a good time to try to get the API as clean as possible.
Prevent FDM-derived properties being sent at full speed (120Hz) which
overloads telnet connections. Instead track dirty properties and
send them at the protocol’s update rate (which is presumably what
the user expects)
