This is not perfect, and we need to more thoroughly address thread safety in the PRC system, but it will nonetheless address a lot of the race condition issues when querying these variables from two threads at the same time.
This requires a macro to override find_package,
as the default behavior in CMake is to fall back
from MODULE onto CONFIG.
Note that Bullet is given a specific override
not to look for a CONFIG, since Bullet tends to
use weird paths in its CONFIG script.
This is preferable because imported targets generally include
all of the relevant information specific to the particular
installation of each package, and without needing to hunt down
a bunch of variables to do it.
To do this, package_option() (which is starting to grow in scope
a little beyond just providing the package option, come to think
of it) is given a new IMPORTED_AS option, which tells the package
configuration system to look for one or more imported targets and
link against them instead.
Instead, let's use a PKG::PKGNAME interface library, which simplifies
the linking and also allows us to use imported libraries from
find_package in the future.
- Rename "controls" terminology for analog inputs to "axes"
- Change some naming of accessors
- Unexpose methods where they are available as properties
- Add serial_number field
- Put battery levels under a "battery" field
This enables the "setters" to behave in a way that people expect setters to behave. Since `setText(None)` now does not behave expectedly, a `clearText()` has also been added to remove the text.
Closes#385
User-defined file handlers are added to a dictionary of default handlers
(just has egg2bam for *.egg files for now). Any user-provided file
handlers for a given file type will overwrite default file handlers.
This allows users to define file handlers without having to re-add
egg2bam to the list.
This should obviate the need for pystub as well.
Note that it's currently a little bit hacky; the source will
have to be moved to make the CMake dependencies work better.
This reimplements the spinlock on top of std::atomic_flag, which is guaranteed to be lockless. It also inserts the PAUSE (REP NOP) instruction which is strongly recommended to be placed in busy-wait loops by Intel.
This also includes a recursive spinlock implementation.
The spinlock implementation is disabled by default, but can be enabled by adding the --override MUTEX_SPINLOCK=1 flag to makepanda.
