2018-09-10hle/service: Default constructors and destructors in the cpp file where ↵Lioncash
applicable When a destructor isn't defaulted into a cpp file, it can cause the use of forward declarations to seemingly fail to compile for non-obvious reasons. It also allows inlining of the construction/destruction logic all over the place where a constructor or destructor is invoked, which can lead to code bloat. This isn't so much a worry here, given the services won't be created and destroyed frequently. The cause of the above mentioned non-obvious errors can be demonstrated as follows: ------- Demonstrative example, if you know how the described error happens, skip forwards ------- Assume we have the following in the header, which we'll call "thing.h": \#include <memory> // Forward declaration. For example purposes, assume the definition // of Object is in some header named "object.h" class Object; class Thing { public: // assume no constructors or destructors are specified here, // or the constructors/destructors are defined as: // // Thing() = default; // ~Thing() = default; // // ... Some interface member functions would be defined here private: std::shared_ptr<Object> obj; }; If this header is included in a cpp file, (which we'll call "main.cpp"), this will result in a compilation error, because even though no destructor is specified, the destructor will still need to be generated by the compiler because std::shared_ptr's destructor is *not* trivial (in other words, it does something other than nothing), as std::shared_ptr's destructor needs to do two things: 1. Decrement the shared reference count of the object being pointed to, and if the reference count decrements to zero, 2. Free the Object instance's memory (aka deallocate the memory it's pointing to). And so the compiler generates the code for the destructor doing this inside main.cpp. Now, keep in mind, the Object forward declaration is not a complete type. All it does is tell the compiler "a type named Object exists" and allows us to use the name in certain situations to avoid a header dependency. So the compiler needs to generate destruction code for Object, but the compiler doesn't know *how* to destruct it. A forward declaration doesn't tell the compiler anything about Object's constructor or destructor. So, the compiler will issue an error in this case because it's undefined behavior to try and deallocate (or construct) an incomplete type and std::shared_ptr and std::unique_ptr make sure this isn't the case internally. Now, if we had defaulted the destructor in "thing.cpp", where we also include "object.h", this would never be an issue, as the destructor would only have its code generated in one place, and it would be in a place where the full class definition of Object would be visible to the compiler. ---------------------- End example ---------------------------- Given these service classes are more than certainly going to change in the future, this defaults the constructors and destructors into the relevant cpp files to make the construction and destruction of all of the services consistent and unlikely to run into cases where forward declarations are indirectly causing compilation errors. It also has the plus of avoiding the need to rebuild several services if destruction logic changes, since it would only be necessary to recompile the single cpp file.

2018-08-31core/core: Replace includes with forward declarations where applicableLioncash
The follow-up to e2457418dae19b889b2ad85255bb95d4cd0e4bff, which replaces most of the includes in the core header with forward declarations. This makes it so that if any of the headers the core header was previously including change, then no one will need to rebuild the bulk of the core, due to core.h being quite a prevalent inclusion. This should make turnaround for changes much faster for developers.

2018-08-08fsp_srv: Use std::string_view's copy() function instead of strncpy()Lioncash
Given elements inserted into a vector are zeroed out, we can just copy MAX_LEN - 1 elements and the data will already be properly null terminated.
2018-08-08fsp_srv: Emplace entries first when building index instead of emplacing lastLioncash
The current way were doing it would require copying a 768 character buffer (part of the Entry struct) to the new element in the vector. Given it's a plain array, std::move won't eliminate that. Instead, we can emplace an instance directly into the destination buffer and then fill it out, avoiding the need to perform any unnecessary copies. Given this is done in a loop, we can request the destination to allocate all of the necessary memory ahead of time, avoiding the need to potentially keep reallocating over and over on every few insertions into the vector.

2018-07-21file_util: Use an enum class for GetUserPath()Lioncash
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.

2018-07-19fsp_srv: Remove unnecessary vector construction in IFile's Write() functionLioncash
We can avoid constructing a std::vector here by simply passing a pointer to the original data and the size of the copy we wish to perform to the backend's Write() function instead, avoiding copying the data where it's otherwise not needed.
2018-07-19fsp_srv: Remove unnecessary std::vector construction in IDirectory's Read() ↵Lioncash
function We were using a second std::vector as a buffer to convert another std::vector's data into a byte sequence, however we can just use pointers to the original data and use them directly with WriteBuffer, which avoids copying the data at all into a separate std::vector. We simply cast the pointers to u8* (which is allowed by the standard, given std::uint8_t is an alias for unsigned char on platforms that we support).

2018-07-19fsp_srv: Respect write length in Write()Lioncash
Previously we were just copying the data whole-sale, even if the length was less than the total data size. This effectively makes the actual_data vector useless, which is likely not intended. Instead, amend this to only copy the given length amount of data. At the same time, we can avoid zeroing out the data before using it by passing iterators to the constructor instead of a size.
