Everything from here is completely unused and also written with the
notion of supporting 32-bit architecture variants in mind. Given the
Switch itself is on a 64-bit architecture, we won't be supporting 32-bit
architectures. If we need specific allocation functions in the future,
it's likely more worthwhile to new functions for that purpose.
Like with TelemetryJson, we can make the implementation details private
and avoid the need to expose httplib to external libraries that need to
use the Client class.
* Added a context menu on the buttons including Clear & Restore Default
* Allow clearing (unsetting) inputs. Added a Clear All button
* Allow restoring a single input to default (instead of all)
operator+ for std::string creates an entirely new string, which is kind
of unnecessary here if we just want to append a null terminator to the
existing one.
Reduces the total amount of potential allocations that need to be done
in the logging path.
First of all they are foundamentally broken. As our convention is that std::string is always UTF-8, these functions assume that the multi-byte character version of TString (std::string) from windows is also in UTF-8, which is almost always wrong. We are not going to build multi-byte character build, and even if we do, this dirty work should be handled by frontend framework early.
We always use unicode internally. Any dirty work of conversion with other codec should be handled by frontend framework (Qt). Further more, ShiftJIS/CP1252 are not special (they are not code set used by 3ds, or any guest/host dependencies we have), so there is no reason to specifically include them
* Stubbed IRS
Currently we have no ideal way of implementing IRS. For the time being we should have the functions stubbed until we come up with a way to emulate IRS properly.
* Added IRS to logging backend
* Forward declared shared memory for irs
MSVC 19.11 (A.K.A. VS 15.3)'s C++ standard library implements P0154R1
(http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2016/p0154r1.html)
which defines two new constants within the <new> header, std::hardware_destructive_interference_size
and std::hardware_constructive_interference_size.
std::hardware_destructive_interference_size defines the minimum
recommended offset between two concurrently-accessed objects to avoid
performance degradation due to contention introduced by the
implementation (with the lower-bound being at least alignof(max_align_t)).
In other words, the minimum offset between objects necessary to avoid
false-sharing.
std::hardware_constructive_interference_size on the other hand defines
the maximum recommended size of contiguous memory occupied by two
objects accessed wth temporal locality by concurrent threads (also
defined to be at least alignof(max_align_t)). In other words the maximum
size to promote true-sharing.
So we can simply use this facility to determine the ideal alignment
size. Unfortunately, only MSVC supports this right now, so we need to
enclose it within an ifdef for the time being.
Multi-line doc comments still need the '<' after the ///, otherwise it's
treated as a regular comment and makes the original doc comment broken
in viewers, IDEs, etc. While we're at it, also fix some typos in the
comments.
The previous form of initializing done here is a C-ism, an empty set of
braces is sufficient for initializing (and doesn't potentially cause
missing brace warnings, given the first member of the struct is a COORD
struct).
Previously core itself was the library containing the code to gather
common information (build info, CPU info, and OS info), however all of
this isn't core-dependent and can be moved to the common code and use
the common interfaces. We can then just call those functions from the
core instead.
This will allow replacing our CPU detection with Xbyak's which has
better detection facilities than ours. It also keeps more
architecture-dependent code in common instead of core.
These currently aren't used and contain commented out source code that
corresponds to Dolphin's JIT. Given our CPU code is organized quite
differently, we shouldn't be keeping this around (at the moment it just
adds to compile times marginally).
The filter is returned via const reference, so this was making a
pointless copy of the entire filter every time a message was being
pushed into the logger instance.
Note: according to cppreference it is necessary to convert char to unsigned char when using std::tolower and std::toupper, otherwise the behaviour would be undefined.
There's no need to perform the resize separately here, since the
constructor allows presizing the buffer.
Also move the empty string check before the construction of the string
to make the early out more straightforward.
This is equivalent to doing:
push_back(std::string(""));
which is likely not to cause issues, assuming a decent std::string
implementation with small-string optimizations implemented in its
design, however it's still a little unnecessary to copy that buffer
regardless. Instead, we can use emplace_back() to directly construct the
empty string within the std::vector instance, eliminating any possible
overhead from the copy.
We can just use the variant of std::string's replace() function that can
replace an occurrence with N copies of the same character, eliminating
the need to allocate a std::string containing a buffer of spaces.
We can just leverage std::unique_ptr to automatically close these for us
in error cases instead of jumping to the end of the function to call
fclose on them.
Instead of using an unsigned int as a parameter and expecting a user to
always pass in the correct values, we can just convert the enum into an
enum class and use that type as the parameter type instead, which makes
the interface more type safe.
We also get rid of the bookkeeping "NUM_" element in the enum by just
using an unordered map. This function is generally low-frequency in
terms of calls (and I'd hope so, considering otherwise would mean we're
slamming the disk with IO all the time) so I'd consider this acceptable
in this case.
This avoids a redundant std::string construction if a key doesn't exist
in the map already.
e.g.
data[key] requires constructing a new default instance of the value in
the map (but this is wasteful, since we're already setting something
into the map over top of it).
Allows avoiding constructing std::string instances, since this only
reads an arbitrary sequence of characters.
We can also make ParseFilterRule() internal, since it doesn't depend on
any private instance state of Filter
These can just use a view to a string since its only comparing against
two names in both cases for matches. This avoids constructing
std::string instances where they aren't necessary.
These are unused and essentially don't provide much benefit either. If
we ever need rotation functions, these can be introduced in a way that
they don't sit in a common_* header and require a bunch of ifdefing to
simply be available
Android and macOS have supported thread_local for quite a while, but
most importantly is that we don't even really need it. Instead of using
a thread-local buffer, we can just return a non-static buffer as a
std::string, avoiding the need for that quality entirely.
