- Modify global_mouseInput in init() and in shutdown(), because *these*
are the places where FGMouseInput is enabled or disabled.
- reinit() does shutdown() followed by init().
Note: the commented-out block starting with "FIXME: memory leak" that is
removed here was just an outdated comment, because SGBindingList
is an std::vector<SGBinding_ptr>, where SGBinding_ptr is a smart
pointer type (SGSharedPtr<SGBinding>). In other words, there was
no leak in this place---at least, not recently.
Create the FGMouseInputPrivate instance in FGMouseInput::init() instead
of in FGMouseInput's constructor. This will allow straightforward
implementation of reinit() via shutdown() and init().
Also get rid of the 'initialized' bool, since bool(d) is now equivalent
(d being the std::unique_ptr<FGMouseInputPrivate> data member of
FGMouseInput).
Using std::vector<mouse_mode> instead of std::unique_ptr<mouse_mode[]>
would have been possible of course, but a bit more awkward as
vector<>::size() returns an std::size_t but all the "adjacent" code is
based on the 'int' type.
Octal escape sequences can be as short as 2 bytes (\0, ..., \7),
therefore they allow one to generate shorter files than hex escapes, for
the same resource contents. The line lengths won't be as even, but this
is purely cosmetic, virtually no one will ever read the resource data
string literals, so this is quite a negligible drawback compared to the
advantage of using less space in the Git repository every time resource
files are committed.
These files were originally included for special trim routines. But these routines are no longer maintained in JSBSim and have already been partially removed from FlightGear.
If running with the launcher, and FG-home is read-only, show a warning
to the user, since this is probably a surprise to them.
(In non-launcher mode we don’t show the box, since it’s more likely to
be an intentional duplicate launch)
The previous priority was PRIORITY_NORMAL, which happens to be higher
than PRIORITY_DEFAULT. Even though the add-on resource provider should
be quite fast at rejecting resource paths that don't start with
'[addon=', I currently can't see any reason that justifies to give it a
higher priority than other paths added to the simgear::ResourceManager
with addBasePath(..., PRIORITY_DEFAULT).
This is another place where the add-on code uses regexps, and so far I
had forgotten to add the fallback code for compilers that don't support
<regex> as per the C++11 standard.
This method takes a string such as "this/is/a/relative/path" and returns
"[addon=ADDON_ID]this/is/a/relative/path", substituting the add-on
identifier for ADDON_ID.
This way, add-on authors don't even have to know the special syntax
'[addon=ADDON_ID]relative/path' used for add-on-specific resource paths,
and don't need to hardcode their add-on identifier inside each such path
either.
This makes it possible to look up files from add-on directories using
for instance FGGlobals::resolve_resource_path(), passing a string such
as "[addon=ADDON_ID]relative/path" as explained in the previous commit.
A resource can be specified with the syntax:
[addon=ADDON_ID]relative/path
Such a resource corresponds to the file $addon_base_path/relative/path
for the specific add-on whose identifier is ADDON_ID.
If the particular add-on isn't registered, looking up such a resource
throws sg_exception.
Replace the previously-written manual calls to "new SomeClass(...)" with
their equivalent using
flightgear::addons::shared_ptr_traits<>::makeStrongRef(). This way, when
SomeClassRef is changed from SGSharedPtr<SomeClass> to
std::shared_ptr<SomeClass>, these calls will magically use
std::make_shared<SomeClass>(...) instead of the "new SomeClass(...)"
call.
Change the arrestor wire handling as follows;
- expose property to indicate when arrestor wire has been snagged: /fdm/jsbsim/systems/hook/arrestor-wire-engaged-hook
- add property to allow the model to request that the wire is released: /fdm/jsbsim/systems/hook/tailhook-release-cmd. This permits an overspeed approach to catch the wire and then drop it.
Jean Pellotier, 2018-01-02 : we don't want interpolation for integer values, they are mostly used
for non linearly changing values (e.g. transponder etc ...)

(everything described here lives in the namespace flightgear::addons)
New classes: Author, Maintainer, and Contact. Author and Maintainer
derive from Contact. For each contact, the following can be defined in
addon-metadata.xml: name, email, and url. See [1] for details about the
syntax and usage policy. Nasal bindings have been updated accordingly,
there are three new ghosts: addons.Contact, addons.Author and
addons.Maintainer.
The enum class UrlType has two new members: author and maintainer. The
Addon::getUrls() method has a new signature:
std::multimap<UrlType, QualifiedUrl> getUrls() const;
because non-empty 'url' fields for authors and maintainers contribute to
the result, and there can be an arbitrary number of authors and an
arbitrary number of maintainers defined for a given add-on---therefore,
std::map can't be used anymore.
Finally, QualifiedUrl has a new field (detail) which stores the author
name (resp. maintainer name) when the QualifiedUrl type is
UrlType::author (resp. UrlType::maintainer). Currently, this 'detail'
field is not used for other URL types, but this could be changed if
desired.

flightgear::addons::shared_ptr_traits allows one to easily switch for
instance from an SGSharedPtr<T> to an std::shared_ptr<T> for "all" uses
of a particular T, and automatically have std::make_shared<T>(...) used
instead of SGSharedPtr<T>(new T(...)) when creating a shared instance of
T. This is interesting because std::make_shared<T>() allocates all
needed memory as one block, whereas std::shared_ptr<T>(new T(args...))
would perform at least two allocations (one for the object T and one for
the control block of the shared pointer).
This is done via static methods (one for each kind of smart pointer):
shared_ptr_traits<SGSharedPtr<T>>::makeStrongRef()
shared_ptr_traits<std::shared_ptr<T>>::makeStrongRef()
that forward their arguments in the same way as std::make_shared<T>().
Normally, <regex> should be available and working in any compliant C++11
implementation, however at least g++ 4.8[1] lies about its C++11
compliance: its <regex> is utterly unusable, see [2] and [3] for
details.
This requires SimGear commit ab1e2d49abdf5b1aca9035a51d9d73d687f0eba7,
for the HAVE_WORKING_STD_REGEX preprocessor symbol.
[1] Which appears to be (precisely 4.8.5) the version shipped in
CentOS 7, and used on FlightGear's current Jenkins installation.

Changes to test_AddonManagement.cxx:
- in testAddonVersionSuffix(), fgtest::initTestGlobals() was called
with the wrong test name (not used anyway, but might be in the
future);
- in testAddon():
* rename variable 'm' to 'addon' ('m' used to stand for the old
class name AddonMetadata);
* call fgtest::initTestGlobals() and fgtest::shutdownTestGlobals()
(not technically needed, but cleaner).
- The Emesary MP bridge can use any string property; however it seems sensible to separate the properties out into a distinct block.
- There is a now a type property for each bridge. This is to allow the bridge to identify its type based on what it can transfer based on function. This will allow rapid filtering of unrequired notifications within the bridge (NYI)
QualifiedUrl is essentially a pair containing an enum value
(addons::UrlType::homePage, addons::UrlType::download, etc.) and an
std::string for the URL per se, with adequate getters and setters.
Addon::getUrls() is for people who wish to process all non-empty URLs
occurring as part of the add-on metadata in batch.

- Parsing of the addon-metadata.xml file is now handled by a new static
method of Addon:
static Addon fromAddonDir(const SGPath& addonPath);
This method will be reusable to gather all add-on metadata from a set
of add-on directories (just call the method once per add-on). This
change also simplifies AddonManager::registerAddonMetadata().
- New supported fields:
authors
maintainers
license/{designation,file,url}
url/{home-page,download,support,code-repository}
tags
See
https://sourceforge.net/p/flightgear/fgdata/ci/next/tree/Docs/README.add-ons
for documentation on these fields.
