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
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.
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.
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.
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).
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.
These operators don't modify internal class state, so they can be made
const member functions. While we're at it, drop the unnecessary inline
keywords. Member functions that are defined in the class declaration are
already inline by default.
This provides the equivalent behavior, but without as much boilerplate.
While we're at it, explicitly default the move constructor, since we
have a move-assignment operator defined.
* Change the logging backend to support multiple sinks through the
Backend Interface
* Add a new set of logging macros to use fmtlib instead.
* Qt: Compile as GUI application on windows to make the console hidden by
default. Add filter configuration and a button to open log location.
* SDL: Migrate to the new logging macros
Additionally, when updating fmtlib, there was a change in fmtlib broke
how the old logging macro was overloaded, so this works around that by
just naming the fmtlib macro impl something different
I decided to overload LogMessage because I don't see a reason to come up with a new function name just for this, but if you guys want me to overload FmtLogMessage instead I'm fine with that.
fmt was updated during the clang-format update, which breaks the previous implementation of FmtLogMessage
Changes were:
* Move definition of FmtLogMessage into log.h to use variadic templates as FMT_VARIADIC was removed
To supplement the change above:
* Move Entry and CreateEntry into log.h
* Add LogEntry in backend.cpp
* Uses PopWait to reduce the amount of busy waiting if there aren't many
new logs
* Opens the log file as shared on windows, letting other programs read
the logs, but not write to them while citra is running
* Flushes the logs to disk if a log >= error arrives
Adds a condition var to SPSCQueue so when a new log is pushed it will
wake the consumer thread that is calling PopWait. This only applies to
to queues with NeedSize=true
* Change the logging backend to support multiple sinks through the
Backend Interface
* Add a new set of logging macros to use fmtlib instead.
* Qt: Compile as GUI application on windows to make the console hidden by
default. Add filter configuration and a button to open log location.
* SDL: Migrate to the new logging macros
swap{16,32,64} are defined as macros on the two, but client code
tries to invoke them as Common::swap{16,32,64}, which naturally
doesn't work. This hack redefines the macros as inline functions
in the Common namespace: the bodies of the functions are the
same as the original macros, but relying on OS-specific
implementation details like this is of course brittle.
Instead of doing complex machinations to keep track of the current bit
index, just unset the lowest bit on each iteration, greatly simplifying
the code.
