While we're at it, we can also improve some of the allocations and
copying that would be going on in one case by preallocating and then
emplacing before modifying.
This might be caused by some packet/status delay within the enet protocol, or may be caused by our not properly handling disconnection. Anyway, this situation *can* happen, and we should not crash Citra for a non-critical error.
This change is not HW tested as I do not have 3 3DSes, but this should make sure that all the members of the network hold the same `node_info`, `nodes` and the bitmasks, etc.
Previously, when connecting, the host was using the incorrect node_id to update `node_info`.
This is an attempt to fix tywald's problem with MH, reported on Discord a while ago. I'm not sure if this would actually fix that though.
I'm not sure why we decided to have a boolean here, but apparently that wasn't the correct behaviour. According to HW tests, the Software Keyboard simply displays the default text when the button text provided is empty (**not necessarily all zero**). For example, if you set a text for one of the buttons and leave others empty, the button you set will have your text, while others will have their default texts. Removed the boolean and updated frontend code to make it correct.
* gl_rasterizer_cache: Mark file-scope functions as static where applicable
Prevents -Wmissing-declaration warnings from occurring and also makes
these functions internally linked.
* gl_rasterizer_cache: Remove unused local std::string variable
Despite being unused, compilers are unable to completely remove any code
gen related to the construction and destruction of this variable, since
the destructor of std::string is non-trivial.
Thus, we can remove it to reduce a minor amount of unnecessary code
generation
* gl_rasterizer_cache: Mark hash implementation as noexcept
This shouldn't throw.
* gl_rasterizer_cache: Remove unused variable in ClearAll()
* gl_rasterizer_cache: Make use of const on references explicit
While declared as auto&, these actually behave as const auto& variables,
due to the constness of the container being iterated. We can make this
explicit for readability sake.
* gl_rasterizer_cache: Resolve truncation warnings
The size is forwarded to a std::memset call, which takes a std::size_t
as its size parameter, so we can just make this change to silence the
warnings.
* gl_rasterizer_cache: Resolve variable shadowing warnings
Prevents a -Wshadow warning from occurring.

It's undefined behavior to pass a null pointer to std::fread and
std::fwrite, even if the length passed in is zero, so we must perform
the precondition checking ourselves.
A common case where this can occur is when passing in the data of an
empty std::vector and size, as an empty vector will typically have a
null internal buffer.
While we're at it, we can move the implementation out of line and add
debug checks against passing in nullptr to std::fread and std::fwrite.
Prevents the internal buffer in the std::optional from being zeroed out
unnecessarily and instead sets the validity byte only in some
implementations.
While we're at it, we can make use of std::move to eliminate unnecessary
heap reallocations from occurring.
Allows us to avoid even more string churn by allowing the AddLine
function to make use of fmt formatting so the string is formatted all at
once instead of concatenating multiple strings.
This is similar to how yuzu's decompiler works, which I've made function
the same way in the past.
Quite a few service functions are stubbed but still pop all their
arguments, which can lead to unused variable warnings.
We can mark the unused arguments with [[maybe_unused]] to silence these
warnings until a full implementation of these functions are made.
Allows implementations to allocate the object and the shared_ptr control
block in one allocation instead of needing to do two separate
allocations.
Also looks much nicer to the reader.
* swkbd: Fix a bug where clicking Cancel hangs the game
The text is validated in `Finalize`. If the validation fails, an error is returned and the applet is not actually finalized. This can result in hangs.
This is usually not a problem as the frontend is expected to validate the text passed to `Finalize`. However, when the user clicked on `Cancel`, the text is ignored and the frontend won't do any validation. Therefore, we should skip the validation here as well.
Also fixed a potential data race. All these functions should now be called on the same thread
* Address review comments
Renamed the fields
Remove close button
This class is memcpy-ed and memcpy has the requirement that data passed
to it must be trivially copyable, otherwise the behavior is undefined.
This is trivial to resolve as BitField was made trivially copyable a
while ago, so this explicit copy assignment operator isn't necessary.
This can be removed as it's not used. Even if it were however, it would
be an incorrect forward declaration, as ServiceManager exists within the
Service::SM namespace, not the top-level SM namespace.
Same behavior, no heap allocation.
strings returned from glGetString() are guaranteed to be static strings,
so this is safe to do. They're also guaranteed to be null-terminated.
Some implementations can use the std::nullopt_t constructor of
std::optional to avoid needing to completely zero out the internal
buffer of the optional and instead only set the validity byte within it.
e.g. Consider the following function:
std::optional<std::vector<ShaderDiskCacheRaw>> fn() {
return {};
}
With libc++ this will result in the following code generation on x86-64:
Fn():
mov rax, rdi
vxorps xmm0, xmm0, xmm0
vmovups ymmword ptr [rdi], ymm0
vzeroupper
ret
With libstdc++, we also get the similar equivalent:
Fn():
vpxor xmm0, xmm0, xmm0
mov rax, rdi
vmovdqu XMMWORD PTR [rdi], xmm0
vmovdqu XMMWORD PTR [rdi+16], xmm0
ret
If we change this function to return std::nullopt instead, then this
simplifies both the code gen from libc++ and libstdc++ down to:
Fn():
mov BYTE PTR [rdi+24], 0
mov rax, rdi
ret
Given how little of a change is necessary to result in better code
generation, this is essentially a "free" very minor optimization.
Previously, we were returning a value that was way too big, causing an integer overflow in Fractured Souls.
According to wwylele, the biggest oberserved save size for 3DS is 1MB, so this new value should leave plenty of room, even if games use a bigger size.
Many of these functions are capable of being used within const contexts,
so we can apply the const qualifier in some cases and add const based
overloads for others, which makes the interface a little bit more
flexible and const-correct.
* core/memory: Amend unusual return value of operator=
operator= usually returns a reference to this. Given there's no comment
explaining why void was used, this can be assumed to be an oversight.
* core/memory: Make use of std::move in Entry::operator=
Same behavior, minus the need for an atomic reference count increment
and decrement (since MemoryRef contains a std::shared_ptr).
* ArmInterface: return ref instead of copy for GetTimer
* ArmInterface: add const ref GetTimer
* ArmInterface: return raw pointer instead of shared_ptr in GetTimer
* remove more unnecessary shared_ptr usage

* am/am: Avoid redundant copy in GetProgramInfoFromCia()
We can just use a reference to the title metadata. Avoids copying
several data entries and std::vector instances that don't need to be
copied.
* hle/service: Avoid redundant copying of std::string
GetUserPath() returns the path as a reference, so we can make use of
said reference to avoid making copies.
By using a reference here, we avoid copying every single element in the
map, each of which contains a std::share_ptr and std::deque containing
std::vectors.
Same behavior, but doesn't result in an allocating copy of the passed in
string. Particularly given the string is only compared against other
existing strings.
Several standard constructors generally check if objects can be moved in
a non-throwing manner (usually via std::move_if_noexcept) to preserve
its exception guarantees. This means that if these were used with
certain containers any reallocations internally would cause resource
churn, as copies would be necessary instead of moves.
This way, if they're every used in that manner, the right behavior is
always performed.
Avoids copying the std::function when we don't need to. Particularly
given the std::function isn't actually stored anywhere, so there's no
need to move it.
Allows interfaces to move the vector into the calls, avoiding any
reallocations.
Many existing call sites already std::move into the parameter, expecting
a move to occur. Only a few remain where this wasn't already
being done, which we can convert over.
This one is similar to the ReceiveCaptureBufferInfo function except it doesn't clear the capture buffer, according to 3dbrew.
This function is used by the Home Menu
The Home Menu uses this to determine whether it is allowed to launch an app (call StartApplication)
This is a no-op for us, we allow any and all titles to be launched. The official APT module holds a list of some forbidden titles like some versions of IronFall and Flipnote Studio 3D.
On Windows, network shares use paths like \\server\share\file which were
being broken by FileUtil::SanitizePath() removing double slashes.
Changed the code in SanitizePath to permit a double-backslash if it
occurs at the start of a filepath (on Windows only).
They are called by the Home Menu during initialization.
These functions will not see much use until we actually implement application jumping and system rebooting. For now we just need them to prevent some unmapped reads in the Home Menu due to the static buffers not being properly set up.
Also rewritten how GetArchiveResource works so that they all use the same interface.
We should decide what to do with these at some point.

* Kernel/Process: Notify the CPUs that a new pagetable has been set every time the process they're executing changes.
Previously the page table would only be changed when the current CPU's page table was changed, this lead to stale JIT states and the PC going to 0 when context-switching a different core inside the ThreadManager::SwitchContext function because the JIT for a new pagetable is only constructed upon receiving the change notification.
* Kernel/Process: Use the relevant CPU's last process to determine when to switch its current process.
Previously it was checking the kernel's current_process variable, which gets overwritten every time a CPU runs its slice. The rescheduling happens after all CPUs have run their slice so the code was effectively only checking the last CPU's process.

From this one can conclude that, for disabled textures, black (0,0,0,1) is the correct colour and clear (0,0,0,0) is not.
* video_core/renderer_opengl/gl_rasterizer_cache: Create Format Reinterpretation Framework
Adds RGBA4 -> RGB5A1 reinterpretation commonly used by virtual console
If no matching surface can be found, ValidateSurface checks for a surface in the cache which is reinterpretable to the requested format.
If that fails, the cache is checked for any surface with a matching bit-width. If one is found, the region is flushed.
If not, the region is checked against dirty_regions to see if it was created entirely on the GPU.
If not, then the surface is flushed.

temporary change to avoid merge conflicts with video dumping
* re-add D24S8->RGBA8 res_scale hack
* adress review comments
* fix dirty region check
* check for surfaces with invalid pixel format, and break logic into separate functions
1. Ensure that register information available to gdbstub is most up-to-date.
2. There's no reason to check for current_thread == thread when emitting a trap.
Doing this results in random hangs whenever a step happens upon a thread switch.
* video_core/renderer_opengl: Move SurfaceParams into its own file
Some of its enums are needed outside of the rasterizer cache
and trying to use it caused circular dependencies.
* video_core/renderer_opengl: Overhaul the texture filter framework
This should make it less intrusive.
Now texture filtering doesn't have any mutable global state.
The texture filters now always upscale to the internal rendering resolution.
This simplifies the logic in UploadGLTexture and it simply takes the role of BlitTextures at the end of the function.
This also prevent extra blitting required when uploading to a framebuffer surface with a mismatched size.
