At first there weren't many enums in Volume.h, but the number has been
growing, and I'm planning to add one more for regions. To not make
Volume.h too large, and to avoid needing to include Volume.h in code
that doesn't use volume objects, I'm moving the enums to a new file.
I'm also turning them into enum classes while I'm at it.
This moves back the WiimoteScanner:Update() call to where it originally
was, since according to a comment it is intended to be called only when
"when not looking for more Wiimotes", and calling it too often causes
the Bluetooth module to be loaded/unloaded a lot of times.
The values are expected to be in the 0.0-1.0 range (as indicated by the
comment), and other parts of Dolphin also expect it to be in that range
since the "full" axis has a -1.0 to 1.0 range. However, this is not
always the case and fvalue can end up being outside of the range. This
clamps fvalue to always be in the 0.0 and 1.0 range.
- Externals/soundtouch/CMakeLists.txt: add -w (since it's not our code) to
silence an unused variable warning
- Source/Core/Core/NetPlayClient.cpp: Work around a Clang/libc++ bug where
initializing a std::array the way the standard says you're supposed to produces
a warning. (libc++'s implementation of std::array, like any sane
implementation, has a C array as a field, so the most explicit form of
initialization would use two braces, one for the struct and one for the array.
Clang has a general warning for not being explicit with braces, which is
usually sane. But the standard only guarantees that initializing std::array
works with a single pair of braces!) There are other places in Dolphin that
incorrectly use double braces, presumably to avoid the warning, so maybe the
warning should just be turned off, but in any case here I just switch to an
equivalent .fill().
This changes Refresh() to use the existing scanning thread to scan for
devices, instead of running the scan on the UI thread and blocking it.
Also makes the UI thread not block when Continuous Scanning is disabled
and removes duplicated code.
Should fix issue 8992.
Under the hood:
* The scanning thread is now always active, even when continuous
scanning is disabled.
* The initialize code which waits for Wiimotes to be connected also
uses the scanning thread instead of scanning on yet another thread.
* The scanning thread now always checks for disconnected devices, to
avoid Dolphin thinking a Wiimote is still connected when it isn't. So
we now check if we need new Wiimotes or a Balance Board at scan time.
This makes it clear that sending a signal a second time will force stop
Dolphin (which is useful in case the GUI is deadlocked or otherwise
unable to react to the signal).
Before this variable was an u8, which could theoretically result in desyncs with a large buffer(greater than 255*120/200=153) filled with blank inputs. If this could actually happen, i don't know. But this part of the code on its own looks like it could break.
A static var is not a good idea, when the value needs to be reset for every session. Also, the variable holds the data size, so it makes sense to set the data size, where the data is added.
This makes DolphinWX shut down cleanly, just like it would with
File->Exit when it receives a SIGINT, SIGTERM (Unix) or some signals
on Windows.
The default signal handler will be restored after a first shutdown
signal so a second signal will exit Dolphin forcefully.
