This changes the read request handler to work just like IOS:
* To make things clearer, we now return early from error conditions,
instead of having nested ifs.
* IOS does an additional check on the requested read length, and
substracts the current seek position from it, if the read would
cause IOS to read past the EOF (not sure what the purpose of this
check is, but IOS does it, so we should too).
* The most significant one: IOS does *not* return the requested read
length, or update the file seek position with it. Instead, it uses
the *actual* read length.
As a result of simply doing what IOS does, this fixes _Mushroom Men_.
The game creates a save file, reads 2560 bytes from it, then
immediately writes 16384 bytes to it. With IOS, the first read does not
change the seek position at all, so the save data is written at
offset 0, not 2560. With Dolphin, the read erroneously set the
seek position to 2560, which caused the data to be written at
the wrong location.
Behavior confirmed by comparing IPC replies with IOS LLE and by looking
at the FS module in IOS.
We (the Microsoft C++ team) use the dolphin project as part of our "Real world code" tests.
I noticed a few issues in windows specific code when building dolphin with the MSVC compiler
in its conformance mode (/permissive-). For more information on /permissive- see our blog
https://blogs.msdn.microsoft.com/vcblog/2016/11/16/permissive-switch/.
These changes are to address 3 different types of issues:
1) Use of qualified names in member declarations
struct A {
void A::f() { } // error C4596: illegal qualified name in member declaration
// remove redundant 'A::' to fix
};
2) Binding a non-const reference to a temporary
struct S{};
// If arg is in 'in' parameter, then it should be made const.
void func(S& arg){}
int main() {
//error C2664: 'void func(S &)': cannot convert argument 1 from 'S' to 'S &'
//note: A non-const reference may only be bound to an lvalue
func( S() );
//Work around this by creating a local, and using it to call the function
S s;
func( s );
}
3) Add missing #include <intrin.h>
Because of the workaround you are using in the code you will need to include
this. This is because of changes in the libraries and not /permissive-
This adds memory values for IOS11, 20, 30, 50, 51, 52, 60 and 70.
Unfortunately, IOS40 (in its working version) is not present on NUS, so
constants for that one are still missing.
This is something I removed by mistake. It didn't break anything in
most titles, but the Mii Channel *requires* write requests to
/dev/usb/kbd to succeed before exiting, so this commit readds the stub.
The latest version has tons of security fixes (which is expected for a
library such as mbedtls).
Updating also allows getting rid of a few deprecation warnings.
Turns out it is completely unneeded and it actually works better
*without* it.
Just try launching the system menu from the HBC; in current master, it
will disconnect the remote and not connect it automatically again. With
this change, it will.
