C++17 allows omitting the mutex type, which makes for both less reading
and more flexibility (e.g. The mutex type can change and all occurrences
don't need to be updated).
Time for yet another new iteration of working around the
"surface destruction during boot" problem...
This time, the strategy is to use a mutex in MainAndroid.cpp.
This is now unused. Seems like it was an improper fix
(there would be a race if saving the screenshot took longer
than 2 seconds) back when it was used too.
It used to be the case that frame advance skipped duplicate frames
(i.e. it would take 30 frame advances to get through one second
of emulated time in a 30 fps game), but this broke in 9c5c3c0.
Skipping duplicate frames making TASing less annoying.
This is related to https://bugs.dolphin-emu.org/issues/10958 which
uses Qt to clear out the window so the game list isn't displayed
while the core is booting. Instead, we use the video backend to
render a black screen, which means Qt doesn't have to flip between
paint engines.
So far in all our uses of ScopeGuard, the type of the callable is
usually just a lambda or a function pointer, so there is no need
to rely on std::function's type erasure.
While the cost of using std::function is probably negligible, it still
causes some unnecessary overhead that can be avoided by making
ScopeGuard a templated class. Thanks to class template argument
deduction in C++17 most existing usages do not even need to be changed.
See https://godbolt.org/z/KcoPni for a comparison between
a ScopeGuard that uses std::function and one that doesn't
Add a function that safely returns whether a character is printable
i.e. whether 0x20 <= c <= 0x7e is true.
This is done in several places in our codebase and it's easy to run
into undefined behaviour if the C version defined in <cctype>
is used instead of this one, since its behaviour is undefined
if the character is not representable as an unsigned char.
This fixes MemoryViewWidget.
This was causing a race which was crashing the FifoCI runners. The main
thread called Stop() which in turn called ResetAllWiimotes() while the
emu thread was still exiting, also shutting down the Wiimote class.
By shifting the reset to the emu thread, all cleanup operations happen
on the same thread where they were initialized.
The workaround was added in 0446a58.
The underlying problem is that we must not destroy the surface
while the video backend is initializing, otherwise the video
backend may reference nullptr.
I've also cleaned up the logic for when to destroy the surface.
Note that the comment in EmulationFragment.java about only being
able to destroy the surface when emulation is running is not true
anymore (due to de632fc, it seems like).
Allows callers to std::move strings into the functions (or automatically
assume the move constructor/move assignment operator for rvalue
references, potentially avoiding copies altogether.
Continues the migration over to using fmt. Given fmt is also compatible
with std::string and std::string_view, we can convert some parameters
over to std::string_view, such as the message parameter for
StopMessage() and the name parameter for an overload of SaveScreenShot()
This was in DolphinWX but not DolphinQt. It's useful for telling if
users who post screenshots have an up-to-date version of Dolphin.
The old implementation of this prepended the version in DolphinWX code
rather than Core code, but I thought it'd be simpler to do it in Core.
MemoryWatcher only works on Linux and affects emulation determinism due
to scheduling additional events, which causes NetPlay to desync.
Considering that this interface is a rather specialized use case, the
communication with it is kinda crappy *and* it's affecting emulation, I
think it's best to just axe it and come up with a better implementation
of the functionality.
Small addition of NetPlay code in Core.cpp was needed to set the
extensions at the right time, as init would override them otherwise.
This solution is more elegant than modifying the user's INI files on
game start.
