Some pieces of code are calling IsRunning because there's some
particular action that only makes sense when emulation is running, for
instance showing the state of the emulated CPU. IsRunning is appropriate
to use for this. Then there are pieces of code that are calling
IsRunning because there's some particular thing they must avoid doing
e.g. when the CPU thread is running or IOS is running. IsRunning isn't
quite appropriate for this. Such code should also be checking for the
states Starting and Stopping. Keep in mind that:
* When the state is Starting, the state can asynchronously change to
Running at any time.
* When we try to stop the core, the state gets set to Stopping before we
take any action to actually stop things.
This commit adds a new method Core::IsUninitialized, and changes all
callers of IsRunning and GetState that look to me like they should be
changed.
Core::GetState reads from four different pieces of state: s_is_stopping,
s_hardware_initialized, s_is_booting, and CPUManager::IsStepping.
I'm keeping that last one as is for now because there's code in Dolphin
that sets it directly, but we can unify the other three to make things
easier to reason about.
This commit also gets rid of s_is_started. This was previously used in
Core::IsRunningAndStarted to ensure true wouldn't be returned until the
CPU thread was started, but it wasn't used in Core::GetState, so
Core::GetState would happily return State::Running after we had
initialized the hardware but before we had initialized the CPU thread.
As far as I know, there are no callers that have any real need to know
whether the boot process is currently initializing the hardware or the
CPU thread. Perhaps once upon a time there was a desire to make the
apploader debuggable, but a long time has passed without anyone stepping
up to implement it, and the way CBoot::RunApploader is implemented makes
it rather difficult. So this commit makes all the functions in Core.cpp
consider the core to still be starting until the CPU thread is started.
Storing the log type names in a map results in them getting re-sorted by
their keys, which doesn't quite give us the sorting we want. In
particular, the Achievements category ended up being sorted at R (for
RetroAchivements) instead of at A. Every use of the map is just
iterating through it, so there's no real reason why it has to be a map
anyway.
Enable emulator hotkeys and controller input (when that option is
enabled) when a TAS Input window has focus, as if it was the render
window instead. This allows TASers to use frame advance and the like
without having to switch the focused window or disabling Hotkeys Require
Window Focus which also picks up keypresses while other apps are active.
Cursor updates are disabled when the TAS Input window has focus, as
otherwise the Wii IR widget (and anything else controlled by the mouse)
becomes unusable. The cursor continues to work normally when the render
window has focus.
There were three distinct mechanisms for signaling symbol changes in DolphinQt: `Host::NotifyMapLoaded`, `MenuBar::NotifySymbolsUpdated`, and `CodeViewWidget::SymbolsChanged`. The behavior of these signals has been consolidated into the new `Host::PPCSymbolsUpdated` signal, which can be emitted from anywhere in DolphinQt to properly update symbols everywhere in DolphinQt.
After reading the previous commit, you might think "hold on, what's the
difference between GetProfileName and GetProfileDirectoryName"? These
two are being used for the exact same thing - figuring out where
profiles are stored - yet they return different values for certain
controllers like GC keyboards! As far as I can tell, the existing code
has been broken for GC keyboards since they were introduced a decade
ago. The GUI (and more recently, also InputCycler) would write and read
profiles in one location, and our code for loading profiles specified in
a game INI file would read profiles in another location.
This commit gets rid of the set of values used by the game INI code in
favor of the other set. This does breaking existing setups where a
GCKey profile has been configured in a game INI, but I think the number
of working such setups is vanishingly small. The alternative would make
existing GCKey profiles go missing from the profile dropdown in the GUI,
which I think would be more disruptive. The alternative would also force
new GCKey profiles into the same directory as GCPad profiles.
This commit also fixes a regression from d6c0f8e749. The Android GUI was
using GetProfileName to figure out what key to use in the game INI,
which made it use incorrect game INI entries for GameCube controller
profiles but not Wii Remote profiles. Now the Android GUI uses
GetProfileKey for this, fixing the problem.
Adds features to improve navigation of Skylanders portal menu, includes:
-List of Skylanders and filters for searching
-Improved buttons for faster loading options
-Added default user folder for storing .sky files
ESCore implements the core functionality that can also be used outside of emulation. ESDevice implements the IOS device and is only available during emulation.
Previously we were translating "w" to "w", which unlike in C++ doesn't
truncate. See https://issuetracker.google.com/issues/180526528, and for
reference, https://en.cppreference.com/w/cpp/io/c/fopen and
https://en.cppreference.com/w/cpp/io/basic_filebuf/open.
This issue was brought to my attention by the recently published issue
CVE-2023-21036 in the screenshot editing tool on Pixel phones. I'm not
aware of any code in Dolphin that actually uses "w" with an existing
file on Android (when we ask the user for a location to save to using
SAF, a new file is always created), but still, best to fix this.
All settings that we care about from an Android perspective are now
supported by the new config system, so we can remove all the Android code
for the old config system. This should have no impact on users.
Up until now, there have been two settings on Android that stored the
selected Wii Remote extension: the normal one that's also used on PC,
and a SharedPreferences one that's used by the overlay controls to
determine what controls to show. It is possible for these two to end up
out of sync, and my input changes have made that more likely to happen.
To fix this, let's rework how the overlay controller setting works.
We don't want it to encode the currently selected Wii Remote extension.
However, we can't simply get rid of the setting, because for some Wii
games we need the ability to switch between a GameCube controller and a
Wii Remote. What this commit does is give the user the option to select
any of the 4 GameCube controllers and any of the 4 Wii Remotes. (Before,
controllers 2-4 weren't available in the overlay.) Could be useful for
things like the Psycho Mantis fight in Metal Gear Solid. I'm also
switching from SharedPreferences to Dolphin.ini while I'm at it.
It's missing a lot of features from the PC version for now, like
buttons for inserting functions and the ability to see what the
expression evaluates to. I mostly just wanted to get something in
place so you can set up rumble.

ButtonManager is very different from how a normal input backend works,
and is making it hard for us to improve controller support on Android.
The following commits will add a new input backend in its place.
This second stack leads to JNI problems on Android, because ART fetches
the address and size of the original stack using pthread functions
(see GetThreadStack in art/runtime/thread.cc), and (presumably) treats
stack addresses outside of the original stack as invalid. (What I don't
understand is why some JNI operations on the CPU thread work fine
despite this but others don't.)
Instead of creating a second stack, let's borrow the approach ART uses:
Use pthread functions to find out the stack's address and size, then
install guard pages at an appropriate location. This lets us get rid
of a workaround we had in the MsgAlert function.
Because we're no longer choosing the stack size ourselves, I've made some
tweaks to where the put the guard pages. Previously we had a stack of
2 MiB and a safe zone of 512 KiB. We now accept stacks as small as 512 KiB
(used on macOS) and use a safe zone of 256 KiB. I feel like this should
be fine, but haven't done much testing beyond "it seems to work".
By the way, on Windows it was already the case that we didn't create
a second stack... But there was a bug in the implementation!
The code for protecting the stack has to run on the CPU thread, since
it's the CPU thread's stack we want to protect, but it was actually
running on EmuThread. This commit fixes that, since now this bug
matters on other operating systems too.
This is the first step of getting rid of the controller indirection
on Android. (Needing a way for touch controls to provide input
to the emulator core is the reason why the controller indirection
exists to begin with as far as I understand it.)
Because of the previous commit, this is needed to stop DolphinQt from
forgetting that the user pressed ignore whenever any part of the config
is changed.
This commit also changes the behavior a bit on DolphinQt: "Ignore for
this session" now applies to the current emulation session instead of
the current Dolphin launch. This matches how it already worked on
Android, and is in my opinion better because it means the user won't
lose out on important panic alerts in a game becase they played another
game first that had repeated panic alerts that they wanted to ignore.
For Android, this commit isn't necessary, but it makes the code cleaner.
