These functions allow to construct a string view from an input buffer, avoiding the copy done by the non string view counterparts. However, callers must be cognizant of the viewed buffer's lifetime to avoid a use-after-free.
The string constructor of UUID states:
Should the input string not meet the above requirements, an assert will be triggered and an invalid UUID is set instead.
This is a fixed and revised implementation of UUID that uses an array of bytes as its internal representation of a UUID instead of a u128 (which was an array of 2 u64s).
In addition to this, the generation of RFC 4122 Version 4 compliant UUIDs is also implemented.
In addition to requiring nanosecond precision, using the native clock requires that the hardware TSC has a precision greater than the emulated CPU and its clock counter.
If the build is from a non-repository, these functions will return empty. This
patch allows using defines to CMake to set version info such as
-DGIT_BRANCH=master.
CallbackStatus instances aren't the cheapest things to copy around
(relative to everything else), given that they're currently 520 bytes in
size and are currently copied numerous times when callbacks are invoked.
Instead, we can pass the status by const reference to avoid all the
copying.
In my testing, waiting for 200ms provided the same level of precision as the previous implementation when estimating the RDTSC frequency.
This significantly improves the yuzu executable launch times since we reduced the wait time from 3 seconds to 200 milliseconds.

VS2022 seems to introduce an optimization when moving vectors to check for equality of the element values. AlignmentAllocator needed to overload the equality operator to fix compilation of its usage in vector moving.
To keep the TAS inputs synced to the game speed even through lag spikes and loading zones, deeper access is required.
First, the `TAS::UpdateThread` has to be executed exactly once per frame. This is done by connecting it to the service method the game calls to pass parameters to the GPU: `Service::VI::QueueBuffer`.
Second, the loading time of new subareas and/or kingdoms (SMO) can vary. To counteract that, the `CPU_BOOST_MODE` can be detected: In the `APM`-interface, the call to enabling/disabling the boost mode can be caught and forwarded to the TASing system, which can pause the script execution if neccessary and enabled in the settings.
First of all, TASing requires a script to play back. The user can select the parent directory at `System -> Filesystem`, next to an option to pause TAS during loads: This requires a "hacky" setup deeper in the code and will be added in the last commit.
Also, Hotkeys are being introduced: CTRL+F5 for playback start/stop, CTRL+F6 for re-reading the script and CTRL+F7 for recording a new script.
The base playback system supports up to 8 controllers (specified by `PLAYER_NUMBER` in `tas_input.h`), which all change their inputs simulataneously when `TAS::UpdateThread` is called.
The recording system uses the controller debugger to read the state of the first controller and forwards that data to the TASing system for recording. Currently, this process sadly is not frame-perfect and pixel-accurate.

The log filter was being ignored on initialization due to the logging instance being initialized before the config instance, so the log filter was set to its default value.
This fixes that oversight, along with using descriptive exceptions instead of abort() calls.
Some system configurations may see visual regressions or lower performance using GPU decoding compared to CPU decoding. This setting provides the option for users to specify their decoding preference.

This fixes a lost wakeup in SPSCQueue. If the reader is in just the right position, the writer's notification will be lost and this will be a problem if the writer then does something to wait on the reader.
This was discovered to affect my upcoming stacktrace PR. I don't think any performance decrease will be noticeable because an uncontended mutex is smart enough to skip the syscall. This PR might also resolve some rare deadlocks but I don't know of any examples.
This implements backtraces so we don't have to tell users how to use gdb anymore.
This prints a backtrace after abort or segfault is detected. It also fixes the log getting cut off with the last line containing only a bracket. This change lets us know what caused a crash not just what happened the few seconds before it.
I only know how to add support for Linux with GCC. Also this doesn't work outside of C/C++ such as in dynarmic or certain parts of graphics drivers. The good thing is that it'll try and just crash again but the stack frames are still there so the core dump will work just like before.
This simplifies the logging system.
This also fixes some lost messages on startup.
The simplification is simple. I removed unused functions and moved most things in the .h to the .cpp. I replaced the unnecessary linked list with its contents laid out as three member variables. Anything that went through the linked list now directly accesses the backends. Generic functions are replaced with those for each specific use case and there aren't many. This change increases coupling but we gain back more KISS and encapsulation.
With those changes it was easy to make it thread-safe. I just removed the mutex and turned a boolean atomic. I was planning to use this thread-safety in my next PR about stacktraces. It was actually async-signal-safety at first but I ended up using a different approach. Anyway getting rid of the linked list is important for that because have the list of backends constantly changing complicates things.
This commit renames the "Services" tab to "Network" and adds a combobox that allows the user to select the network interface that yuzu should use. This new setting is now used to get the local IP address in Network::GetHostIPv4Address. This prevents yuzu from selecting the wrong network interface and thus using the wrong IP address. The return type of Network::GetHostIPv4Adress has also been changed.
According to https://stackoverflow.com/questions/469508, we run into a
MSVC bug (since VS 2005) when using diamond inheritance for
RangedSetting.
This explicitly implements those functions in RangedSetting. GetValue is
implemented as just calling the inherited version. The explicit
converson operator is reimplemented. I opted for this over ignoring the
warning with a pragma since this specifies the inherited behavior, and I
have now less faith in MSVC to pick the right one.
In addition, we mark destructors as virtual to silence what I believe is
a fair MSVC compilation error.
Fixes a theoretical scenario where a Setting is using the BasicSetting's
GetValue function. In practice this probably only happens on yuzu-cmd,
where there is no need for a Setting's additional features. Need to fix
regardless.
Use VK_KHR_pipeline_executable_properties when enabled and available to
log statistics about the pipeline cache in a game.
For example, this is on Turing GPUs when generating a pipeline cache
from Super Smash Bros. Ultimate:
Average pipeline statistics
==========================================
Code size: 6433.167
Register count: 32.939
More advanced results could be presented, at the moment it's just an
average of all 3D and compute pipelines.
This setting is best referred to as a speed limit, as it involves the limits of all timing based aspects of the emulator, not only framerate.
This allows us to differentiate it from the fps unlocker setting.
GLASM is getting good enough that we can move it out of advanced
graphics settings. This removes the setting `use_assembly_shaders`,
opting for a enum class `shader_backend`. This comes with the benefits
that it is extensible for additional shader backends besides GLSL and
GLASM, and this will work better with a QComboBox.
Qt removes the related assembly shader setting from the Advanced
Graphics section and places it as a new QComboBox in the API Settings
group. This will replace the Vulkan device selector when OpenGL is
selected.
Additionally, mark all of the custom anisotropic filtering settings as
"WILL BREAK THINGS", as that is the case with a select few games.
Mostly fixing unused *, implicit conversion, braced scalar init,
fpermissive, and some others.
Some Clang errors likely remain in video_core, and std::ranges is still

Some titles crash if the FPS limit is disabled when launching. This change ensures that titles launch with the limit in-place to avoid issues.
In order to simplify the change, the UI toggle was removed as it will always be overridden at launch to be disabled.
The setting can still be toggled during gameplay with the hotkey, and indicated by the fps label in the status bar.
Decouples the CPU debugging mode from the enumeration to its own
boolean. After this, it moves the CPU Debugging tab over to a sub tab
underneath the Debug tab in the configuration UI.
Old CPU Accuracy setting won't translate well into since we're adding
one at the beginning of the list. On first boot with the new setting,
just use the default setting.
The current CPU accuracy settings in yuzu are fairly polarized and
require more than common knowledge to know what the optimal settings for
yuzu would be. This adds a curated option called 'Auto' that applies a
few at the moment known-good unsafe optimizations to Dynarmic.
Slight improvements to readability.
Dropped suggestions for string_view (settings.h:101), pass by value
(settings.h:82), reverting double to a float (config.cpp:316), and other
smaller ones, some out of scope.

There's no point in keeping the file open after the write limit is exceeded. This allows the file to be committed to the disk shortly after it is closed and avoids redundantly checking whether or not the write limit is exceeded.
It became apparent that logging can continuously spam errors that trigger file flushing.
Since committing the files to disk is an expensive operation, this causes unnecessarily high disk usage.
As such, we will revert Flush() to the previous behavior and add a Commit() member function in the event that this behavior is needed.
Creates a new BasicSettings class in common/settings, and forces setting
a default and label for each setting that uses it in common/settings.
Moves defaults and labels from both frontends into common settings.
Creates a helper function in each frontend to facillitate reading the
settings now with the new default and label properties.
Settings::Setting is also now a subclass of Settings::BasicSetting. Also
adds documentation for both Setting and BasicSetting.
Removes common_sizes.h in favor of having `_KiB`, `_MiB`, `_GiB`, etc
user-literals within literals.h.
To keep the global namespace clean, users will have to use:
```
using namespace Common::Literals;
```
to access these literals.
This check was preventing files with the Write or Append file access modes from being created, as per the documented behavior in FileAccessMode.
This amends the check to test for the existence of a filesystem object prior to checking whether it is a regular file.
Thanks to liushuyu for pointing out that removing the check altogether would not guard against attempting to open non-regular files such as directories, symlinks, FIFO (pipes), sockets, block devices, or character devices.
The documentation has also been updated for these functions to clarify that a file refers to a regular file.
Similarly, Flush() is typically called to attempt to flush a file into the disk. In the one case where this is used, we do not care whether the flush has succeeded or not, making [[nodiscard]] unnecessary.
There are a lot of scenarios where we don't particularly care whether or not the removal operation and just simply attempt a removal.
As such, removing the [[nodiscard]] attribute is best for these functions.
If this is not waited on, the synchronization primitives are destroyed
whe main exits and the detached task ends up signalling garbage and not
properly finishing.
This introduces a new setting Enable FS Access Log which saves the filesystem access log to sdmc:/FsAccessLog.txt
If this setting is not enabled, this will indicate to FS to not call OutputAccessLogToSdCard.
Fixes softlocks during loading in Xenoblade Chronicles 2 when certain DLC is enabled.
std::fflush does not guarantee that file buffers are flushed to the disk.
Use _commit on Windows and fsync on all other OSes to ensure that the file is flushed to the disk.
MSVC's implementation of recursive_directory_iterator throws an exception on an error despite a std::error_code being passed into its constructor. This is most likely a bug in MSVC's implementation since directory_iterator does not throw an exception on an error.
We can replace the usage of recursive_directory_iterator for now until MSVC fixes their implementation of it.
This falls back to the old approach of using a virtual buffer.
Windows is untested, but this build should fix support for Windows < 10 v1803. However without fastmem support at all.
These macros all interact with the result code type, so they should
ideally be within this file as well, so all the common_funcs machinery

- This is a developer-only setting and no longer needs to be enabled by default.
- Also adds "use_auto_stub" setting to SDL frontend while we are here.
- Supersedes #1340.
It shall block until there is something to consume in the queue.
And use it for the GPU emulation instead of the spin loop.
This is only in booting the emulator, however in BOTW this is the case for about 1 second.
Advantage: Altering the handler does not need a full recompilation.
Disadvantage: noreturn is droped, so the caller is a bit slower.
We quite often run yuzu with a YOLO assertion handler. In fact, only very few
games run at all with asserts. This patch allows developers to patch the handler
without recompiling everything. The overhead of the missing "noreturn" attribute
shoul be negletable.
`network.cpp` has several error paths which either:
- report "Unhandled host socket error=n" and return `SUCCESS`, or
- switch on a few possible errors, log them, and translate them to
Errno; the same switch statement is copied and pasted in multiple
places in the code
Convert these paths to use a helper function `GetAndLogLastError`, which
is roughly the equivalent of one of the switch statements, but:
- handling more cases (both ones that were already in `Errno`, and a few
more I added), and
- using OS functions to convert the error to a string when logging, so
it'll describe the error even if it's not one of the ones in the
switch statement.
- To handle this, refactor the logic in `GetLastErrorMsg` to expose a
new function `NativeErrorToString` which takes the error number
explicitly as an argument. And improve the Windows version a bit.
Also, add a test which exercises two random error paths.
- With using unique_ptr instead of shared_ptr, we have more explicit ownership of the context.
- Fixes a memory leak due to circular reference of the shared pointer.
- Previous optimized impl. resulted in an integer overflow, so revert.
- This is our slow/fallback path that should never be really be used, so the optimization in unimportant.
