control copter floor fence with autoenable
autoenable floor fence with a margin
check for manual recovery only after having checked the fences
make auto-disabling for minimum altitude fence an option
output message when fence floor auto-enabled
re-use fence floor auto-enable/disable from plane
auto-disable on landing
do not update enable parameter when controlling through mavlink
make sure get_enabled_fences() actually returns enabled fences.
make current fences enabled internal state rather than persistent
implement auto options correctly and on copter
add fence names utility
use ExpandingString for constructing fence names
correctly check whether fences are enabled or not and disable min alt for landing in all auto modes
add enable_configured() for use by mavlink and rc
add events for all fence types
make sure that auto fences are no longer candidates after manual updates
add fence debug
make sure rc switch is the ultimate authority on fences
reset auto mask when enabling or disabling fencing
ensure auto-enable on arming works as intended
simplify printing fence notices
reset autofences when auot-enablement is changed
output fence breach type
when switching mode without a fence action do not go into manual recovery
only recover if there is a fence action
implement auto-takeoff fence options
output user-friendly fence names
auto-enable fences on auto-takeoff
use fence enable_configured()
simplify message printing
Fixes the following issues:
* Compound array elements subject to tail array optimization could be
decoded incorrectly, causing a decode failure.
* Invalid array lengths could be sent over the wire if a
longer-than-max array was encoded (though only the max number of
elements was sent).
* Lengths were not validated when decoding arrays of compound elements
using TAO, causing memory corruption if an invalid length was received.
* Union tags were not validated, causing undefined behavior if an
invalid tag was received.
When stall prevention is enabled we were scaling from the aircraft's
minimum flight speed. However this is normally already picked as being
above the stall speed, and for a variety of reasons we may want to pin
the aircraft at a higher minimum speed. But if the aircraft was
commanded to fly to close to that minimum speed as soon as it banked for
a pattern it would command a increase in speed to keep it away from
stalling. However if your minimum speed is far from stalling this
increase was incorrect. To make it worse what this actually results in
happening is an aircraft diving for more speed (over 10 m/s on some
aircraft) as well as descending to gain that speed resulting in over 200
foot deviations in altitude control.
Only create the binding object (singleton metatable/userdata or C
function reference) once the user first references a particular
singleton or userdata creation function. Once created, the object is
stored into the script's environment so it doesn't get recreated on the
next reference and there isn't any further overhead. The userdatas are
no longer shared between scripts which imposes a slight memory penalty
for multiple scripts using the same singleton but this avoids an
additional lookup time cost.
Userdata and ap_objects aren't eligible for this optimization as the C++
code might want a particular metatable at any time.
Saves ~9.3K Lua heap.
The global table is then used as the __index metamethod of each state's
environment table. Avoids the overhead of loading binding objects into
each state. The binding objects are immutable from Lua so sandboxing is
not violated.
Does have the slight downside that a script can no longer know all the
binding names by enumerating _ENV.
Saves ~700B of memory per loaded script.
The __call metamethod was set to the metatable itself. With __call not
present, Lua will try to call the metatable (and fail), which is the
same behavior as with the __call metamethod set to the metatable.
Saves ~2K Lua heap.
