Changes:
- `ShowDevelopmentWarning` is now under the '[Interface]' group in
Dolphin.ini, with other interface-related settings. So, whoever uses
DolphinQt will have to edit that manually again. Sorry!
- Game search paths and the last file are now shared properly with
DolphinWX
- Qt-only preferences like "Preferred View: list/table" are now
stored using the platform's native settings storage, rather than in
UI.ini
struct GekkoOPTemplate was implemented differently in different
compilation units, which breaks the ODR and could end up causing issues
as symbols exported from one compilation unit could end up being used by
another even if they have different implementations.
This puts them in an anonymous namespace, restricting any generated
symbols to the single compilation unit.
Some code was calling more than one of these functions in a row
(in particular, FileUtil.cpp itself did it a lot...), which is
a waste since it's possible to call stat a single time and then
read all three values from the stat struct. This commit adds a
File::FileInfo class that calls stat once on construction and
then lets Exists/IsDirectory/GetSize be executed very quickly.
The performance improvement mostly matters for functions that
can be handling a lot of files, such as File::ScanDirectoryTree.
I've also done some cleanup in code that uses these functions.
For instance, some code had checks like !Exists() || !IsDirectory(),
which is functionally equivalent to !IsDirectory(), and some
code was using File::GetSize even though there was an IOFile
object that the code could call GetSize on.
The MonoSpaceFont of the LogWindow was using a Windows native way to
specify a font name.
Now it's using wxFONTFAMILY_TELETYPE.
On Win32 it will additionally request the specific font name "Consolas",
so it doesn't use ugly "Courier New". I pilfered that specialization
from Source/Core/DolphinWX/Cheats/ARCodeAddEdit.cpp.
Before, if you extracted a directory like /map/Final/Release/,
Dolphin would create the nested folders map, Final and Release
in the output directory and put the files in Release instead of
just putting the files directly in the output directory.
While setting up a proper NAND for Wii emulation has become much easier
now that disc and online system updates work, they still require users
to have a recent disc game, certificates extracted from IOS or a NAND
dump for online updates to work and to really get all system titles.
This commit adds the ability to do an online update right from
Dolphin itself, which solves that usability issue.
Allows reusing the WAD import logic more easily, whereas UICommon
code can only be used from UICommon and UI.
And managing what's on the NAND is the Core's responsability, not UI.
It didn't work when there were non-ASCII characters
in the directories argument, but it worked fine with
non-ASCII characters in names of found files and folders.
* IOS: WiiRoot shutdown was moved to HW.
* Movie: Don't call UpdateWantDeterminism() if we're not running yet,
because this will automatically be done during the boot process.
Not doing this will result in two NANDs being created.
This is larger than I thought I would be, but unfortunately it's quite
hard to split fixes like this when the handling is wrong in tons of
different places.
The content table is limited in size. It can only hold 16 entries.
Three consequences:
* Since the table cannot grow indefinitely, instead of using a std::map
we use a std::array as we should.
* Remove a hack where the CFD was cleared back to 0 on IPC close (wtf?)
* The CFD now doesn't keep increasing to infinity. It's unknown if this
would fix anything at all, but some issues in the past were caused
by CFDs being excessively large.
Other minor changes:
* Simplify save state logic.
* Keep track of the UID like ES does. Not sure how useful this is, but
we can do this very easily so why not.
* Remove the guesswork and use the actual error codes.
* Add more error checking to make Dolphin less likely to crash.
Something that should be done in the future: deduplicate the filesystem
logic. Something that takes one line in the actual ES code takes
10+ lines in our implementation... while duplicating the FS logic...
This will likely harder to fix though, so I'm leaving that
for another time.
It seems to make no difference besides allowing lower latencies and more
stability on hardware OpenAL cards. Maybe the Wait() call waits for too
long, causing buffers underruns.
Before these changes each value of latency were actually 5ms, with a
minimum latency of ~10 ms. If it was set to 4 ms on the UI, the actual
latency was 10 + 5 * 4 = 30 ms.
Now 30 ms on the UI means 30 ms on the backend.
c5fa470 made the extension check discard directories, but
only in the new code that currently only is used on Windows.
Let's add an equivalent check in the old code so that the
behavior is consistent across platforms.
This seems like an oversight in the old code, because
what's the point of loading user files if the titles
in them are going to be ignored for nearly all games?
This commit fixes the issue by making the first LoadMap
variant not overwrite entries and making the constructor
do everything in the opposite order. An alternative solution
would be to make the second LoadMap variant overwrite entries.
This fixes the global-static fifo object causing infinite hangs in some
cases. Notably, failure to initialize a graphics backend would result in
BlockingLoop::Prepare being called but never executing Run(), leaving the
object in a bad state.
The sanity check runs *before* finalising the import, so at that time
the whole title directory is still in /import and not in /title.
This means we should check for contents there, not in /title. Whoops.
The efficient function (that is nearly the same as
https://graphics.stanford.edu/~seander/bithacks.html#DetermineIfPowerOf2)
replaces one loop based instance (which also reused the xx variable
afterwards, whereas it should have used htabmask instead) and one
instance using the population count a.k.a. Hamming weigth.
This one verifies bitmasks where low bits are set to 1 (hence the name).
Any stray 0 among the lower ones or any stray 1 among the higher zeros
renders the mask invalid.
The edge cases of all zeros and all ones are considered valid masks.
It uses an efficient implementation. It's the counterpart of
https://graphics.stanford.edu/~seander/bithacks.html#DetermineIfPowerOf2
Simpler, and puts the call to CheckIntegrity right where it should be,
instead of being hidden somewhere in a thread class.
This also makes it more obvious what we're getting from the async task.
Oh, and coincidentally, this fixes a random crash that could occur
during the check. I'm not sure why.
This adds a check to ImportTitleDone to make sure all required contents
that are listed in the TMD have been imported before allowing to finish
the import. Not checking for this could allow titles to be left in an
inconsistent state.
There seems to be a race condition between a peripheral device
connecting to the bluetooth controller and it being ready to use.
It's very short and it depends upon the controller, some appear to
connect synchronously and block until the device is ready, others
report the device upon discovery but do not allow communication straight
away. I don't know which is the correct behaviour, or whether it depends
on the peripheral, controller or both. Anyway, Dolphin waits for a
remote to appear and immediately attempts to open the communication
channels, this can fail because the device isn't ready yet, delay, try
again, and it works.
There are other (unlikely) chances the device is busy at random
moments after this initial race condition so it loops around try to
reconnect.
This was inspired by an earlier patch, see here:
https://bugs.dolphin-emu.org/issues/5997#note-20
I can confirm that it works perfectly for me on a bluetooth
controller where otherwise it's impossible to connect (Dell 380
Bluetooth 4.0).
So, a FifoRecorder instance is instantiated as a file-local variable and
used as a singleton (ugh). Most users likely don't regularly use the
FIFO player/FIFO recorder, so this is kind of a substantial waste of
memory.
FifoRecorder's internal RAM and ExRAM vectors are 33554432 and 67108864
bytes respectively, which is around 100.66MB in total.
Just on the game list view on a clean build with nothing loaded, this
knocks debug build memory usage down from ~232.4MB to ~137.5MB, and
release build memory usage down from ~101MB to ~5.7MB.
The GameCube IPL sounds the same when using the free ROM as it does when
using the official ROM (and in Audacity, I couldn't visually distinguish
between the waveforms). It has a reference to an unimplemented function
at 0x8644 which seems to only be used in an inlined version of the CARD
ucode.
This allows the user to go through the Wii Menu first boot setup
screen when they launch the System Menu for the first time.
Most useful on a clean profile, after doing a full system update,
to configure settings like the console country.
This rewrites the SysConf code for several reasons:
* Modernising the SysConf class. The naming was entirely cleaned up.
constexpr for constants.
* Exposing less stuff in the header.
* Probably less efficient parsing and writing logic, but much simpler
to understand and use in my opinion. No more hardcoded offsets.
No more duplicated code for the initial SYSCONF generation.
* More flexibility. It is now possible to add and remove entries,
since we rebuild the file. This allows us to stop spamming
"section not found" panic alerts; we can now use and insert
default entries.
On a real Wii, the title list is not in any particular order. However,
because of how the flash filesystem works, titles such as 1-2 are
*never* in the first position. We must keep this behaviour, or some
versions of the System Menu may break.
Will be used from several functions to verify the signatures for
different containers (TMDs, tickets, device signed blobs).
An option was added to disable signature checks, because that could be
useful for people trying to import unsigned stuff.
stat() returns an error code in errno on both POSIX compliant
platforms and Windows.
This means we should always use errno instead of GetLastErrorMsg
which uses GetLastError() (Win32) on Windows.
POSIX allows one or more trailing slashes for directories.
From POSIX.1-2008, section 3.271 (Base Definitions / Pathname):
> A pathname can optionally contain one or more trailing <slash>
> characters. Multiple successive <slash> characters are considered to
> be the same as one <slash>, except for the case of exactly two
> leading <slash> characters.
On Windows, the extra trailing slashes are ignored for directories too.
