FS subfiles are created with File::OpenSubFile, they have a start offset that must be added to all read/write operations.
The implementation in this commit is done using a new FileBackend that wraps the FS::File along with the start offset.
boost::static_pointer_cast for boost::intrusive_ptr (what SharedPtr is),
takes its parameter by const reference. Given that, it means that this
std::move doesn't actually do anything other than obscure what the
function's actual behavior is, so we can remove this. To clarify, this
would only do something if the parameter was either taking its argument
by value, by non-const ref, or by rvalue-reference.
This can just be a regular function, getting rid of the need to also
explicitly undef the define at the end of the file. Given FuncReturn()
was already converted into a function, it's #undef can also be removed.
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.
There were a few places where nested namespace specifiers weren't being
used where they could be within the service code. This amends that to
make the namespacing a tiny bit more compact.
While likely very uncommon, this sanitizes the input and does nothing in
the event of the length being equal to or less than zero, avoiding
constructing a std::string when there's no need to. It also avoids an
out-of-memory scenario, as a negative value would wrap around to its
equivalent unsigned representation in std::string's constructor.
e.g. If someone was silly and a length of -1 was specified, this would
make a string with a length of 0xFFFFFFFFFFFFFFFF on a 64-bit platform,
which will obviously eventually fail due to the allocation being way too
large.
Previously, these were sitting outside of the Kernel namespace, which
doesn't really make sense, given they're related to the Thread class
which is within the Kernel namespace.
* Add ZeroMQ external submodule

* Added start of ZeroMQ RPC Server implementation.
* Request construction and callback request handling
* Read and write memory implementation
* Add ID to request format and send reply
* Add RPC setting to macOS UI
* Fixed initialization order bug and added exception handling
* Working read-write through Python
* Update CMakeLists for libzmq to resolve target name conflict on Windows
* Platform-specific CMake definitions for Windows/non-Windows
* Add comments
* Revert "Add RPC setting to macOS UI"
* Always run RPC server instead of configurable
* Add Python scripting example. Updated .gitignore
* Rename member variables to remove trailing underscore
* Finally got libzmq external project building on macOS
* Add missing dependency during libzmq build
* Adding more missing dependencies [skip ci]
* Only build what is required from libzmq
* Extra length checks on client input
* Call InvalidateCacheRange after memory write
* Revert MinGW change. Fix clang-format. Improve error handling in request/reply. Allow any length of data read/write in Python.
* Re-organized RPC static global state into a proper class. [skip ci]
* Make sure libzmq always builds in Release mode
* Renamed Request to Packet since Request and Reply are the same thing
* Moved request fulfillment out of Packet and into RPCServer
* Change request thread from sleep to condition variable
