infoxml.cpp: Thread device processing. Gives about a 10% speed
improvement overall, and avoids the need to mess with the locale of the
ultimate output stream.
debugger/win/consolewininfo.cpp: Show image mount/create error messages
on the console.
emu/devdelegate.h, util/delegate.h: Added deduction guides for common
delegate creation patterns (only used in sega/segas16a.cpp so far).
More noexcept on things that have no business throwing exceptions.

Use VirtualAlloc rather than VirtualProtect on Windows to change page
protection, as the latter can cause severe performance issues with some
antivirus software.
Added noexcept to lots of hash- and bitmap-related things, and added a
little more error checking. Yes, I realise it will abort if an
allocation fails while printing a log message, but if you get to that
point, you're probably screwed already.

Restores ability to give specific/detailed messages removed in
6f7e4141ea14acaaf9cb973c66788fabb3457023 while pandering to obsession
with single return value.
Moved responsibility for displaying the error message in the UI to the
caller rather than device_image_interface, and made
device_image_interface always log the error along with the full path and
error condition content.
Gave several image devices more detailed error messages. Added some
FIXME comments for apparent bugs.

bus/nubus/nubus_image.cpp: Fixed failure to allocate memory for the
image (regressed in b8c338858a101d14308c64c87b0f714db4f05326).
bus/nes/karastudio.cpp, bus/nes/sunsoft_dcs.cpp: Fixed stack smash when
loading loose software.
Addressed some Lua engine fallout from running things in coroutines:
* Don't crash accessing dead Lua thread state from callbacks.
* Allow returning values via yielding functions.
* Don't run address space tap and layout view callbacks in coroutines to
save overhead.
* Better logging of errors from callbacks.
|
| |
|
|
|
|
|
| |
Also edited a pile of copy/pasted comments and made some minor code
cleanups (reducing variable scope, etc.).

- Remove the seterror method for recording error messages and conditions. Condition codes have been made return values for call_load, call_create and various related callbacks. Error messages (which many devices weren't generating) are now displayed through osd_printf_error.
- Eliminate the image_init_result and image_verify_result pass/fail enumeration types. Update many functions that were returning these enumerations or simply bools to return std::error_condition instead. In some cases, this type is now passed down from internal parsing/loading functions which were already returning it. In various other cases, the former default UNSPECIFIED has been used as a catchall for I/O errors; anticipated future refactorings should make these error returns more specific.
- Expand the image_error categories to include INVALIDLENGTH, NOSOFTWARE and BADSOFTWARE. The first is largely self-explanatory. The second is generated by the core to indicate failure to find software items in lists. The third is provided for devices to indicate semantic errors in software list entries.
- Change the return type of floppy_image_device::identify to a pair so the potential error condition can be passed along to the UI without storing it in a member variable.
- Move device_image_interface::message down into snapshot_image_device and change its implementation to use string_format instead of printf.
- Correct a typo in the shortname of the generic snapshot device.

util/bitmap.cpp, util/palette.cpp: Marked lots of things constexpr.
Bitmaps don't throw exceptions on allocation failure, they just become
invalid. Almost nothing in MAME actually checks for this.
emu/profiler.cpp: Abort if the profile stack overflows rather than
throwing an exception. This is a developer feature and if it overflows,
the code is broken. Calling a noreturn noexcept function generates less
code than throwing an exception, which adds up.
util/strformat.cpp: Traded away some unnecessary flexibility for more
compact code. The stream objects must derive from std::basic_ostream
now - they can't just be any old objects with the expected operators.

* This lets you use emu.wait(...) directly without mucking around creating coroutines.
* Allow emu.wait to accept an attotime argument.
* Added a couple more wait helper functions.
-emu/profiler.h: Actually use scope-based profiling helpers.
* This makes the comment at the top of emu/profile.h less dishonest, and makes it easier to write exception-safe code.
* Got rid of some do { ... } while (0) loops that only existed so break could be used like a goto.

Functionally, the only difference between the system definitions is that
GAMEL lets you specify an additional internal layout and SYST lets you
specify a compatible system. COMP and CONS are just aliases for SYST -
the aliases can be phased out.
Removed arcade.flt and mess.flt altogether - opinion seems to be split
between misinterpreting them as fully supported and considering them
unnecessary. They were marginally useful as a performance test for
makedep.py, but that isn't important. We still have nl.flt as an
example .flt file (although it doesn't use "-" exclude directives).
Moved the UI active flag from the machine to the UI manager. Nothing
else uses it anyway (it's still accessible to scripts).

This avoids creating a table every time the state property of a device
is accessed, adds proper support for getting/setting floating/point
state entries from Lua, calls the state entry's formatting method to
convert to a string (for flags fields, etc.) and exposes more
properties.
This is a breaking change as the exposed properties on state entries
have changed, and the value property has different semantics for
floating-point state entries.

* Can now cycle through candidates by repeatedly pushing Tab.
* Also cleaned up Lua thread context object a little, and made it
possible to pass any Lua object as a status value.

Compile Lua as C++. When Lua is compiled as C, it uses setjmp/longjmp
for error handling, resulting in failure to unwind intermediate stack
frames. Trying to ensure no objects with non-trivial destructors are in
scope when raising a Lua error is error-prone. In particular,
converting an exception to a Lua error becomes convoluted, and raising a
Lua error from a constructor is effectively impossible.
Updated Lua to 5.4.4 - this includes a brand-new garbage collector
implementation with better performance. The main thing removed is the
deprecated bitlib.
Updated sol2 to version 3.3.0 - this adds support for Lua 5.4 and fixes
a number of issues, including not correctly handling errors when Lua is
built as C++.
Updated LuaFileSystem to version 1.8.0 - this adds support for symbolic
links on Windows, as well as Lua 5.4 compatibility.
Updated LuaSQLite3 to version 0.9.5 - this fixes issues in
multi-threaded environments, as well as Lua 5.4 compatibility.
Fixed double-free after attempting to construct a debugger expression
from Lua with an invalid string, and exposed expression error to Lua in
a better way.
Added warning level print function to Lua.
Fixed saving cheats with shift operators in expressions, although this
code isn't actually used as there's no cheat editor.

There are multiple issues with what MAME was doing, but the most glaring
is that it violates the DirectInput interface contract that requires the
window associated with an open device must not be destroyed. See
documentation for IDirectInputDevice8::SetCooperativeLevel: "This
parameter must be a valid top-level window handle that belongs to the
process. The window associated with the device must not be destroyed
while it is still active in a DirectInput device."
The previous code also prevented DirectInput controllers from working
when using multiple windows if any window other than the first window
had focus.
Also fixed SDL builds not correctly recognising when all windows lose
focus, and save state menu not appearing.

* cpu/dsp56156: Removed vestigial (and excessively slow) "new" execution code.
* apple/bandit.cpp: Got rid of unnecessary friend declaration.

This fixes "amplification" effects that would happen if the frame rate
rose above 100 Hz (whether by unthrottling or otherwise).
Synchronise with wall clock any time inputs are read. Not doing this
has weird effects on relative inputs with frame skipping and contributes
to unresponsiveness of menus.
Reduce visual latency for mouse movement on menus when paused or
skipping frames. The rest of the code changes to menus won't provide
benefits until draw can happen after event handling.

osd/modules/input, emu/inpttype.cpp: Made most default joystick
assignments supplied by input modules. Input modules take available
controls into consideration when generating default assignments.
emu/inpttype.ipp: Added a separate "Back" UI input separate from Cancel.
You may want an easier to hit combination for moving to the previous
menu than for exiting or cancelling input. They both default to Escape.
emu/inpttype.ipp: Added a UI Help control. Currently only used by
analog inputs menu
emu/inpttype.h: Moved I/O port field type enum to its own header and
sorted UI controls so they appear in a more logical order.
ui: Don't use UI Select to restore defaults - people should be getting
used to the UI Clear input by now. UI Select cycles multi-value items
instead.
ui/inputmap.cpp: Don't use immediate cancel to cycle between clearing
and restoring default assignment (use UI Clear instead).
osd: Reduced the number of files needing to include the dreaded emu.h.
Got some implementation out of headers.

emu/input.cpp: Fixed regression in display of some joystick inputs.
osd/interface: Split up interface classes into a few more files to
reduce where the input device interface class needs to be included.
Made OSD independent of concrete input_device class.
osd/modules/input, emu/inputdev.cpp, emu/ioport.cpp: Allow input devices
to provide tokens for controls without standard item types and
additional default input assignments. Fixes issues assigning Yen and
Backslash on Japanese keyboards.
ui/textbox.cpp: Added a fixed-content text box menu class for future
use.
Got main.h out of emu.h as it’s only used in a very small number of
places, mostly for getting the application name. Added eminline.h to
attotime.h as it's used without emu.h. Cleaned up forward declarations
in emufwd.h a little.

osd: Supply OSD object to modules on initialisation. Encapsulated some
event handling in the OSD objects rather than leaving it in free
functions. Put various stuff in namespaces.
osd/modules/input: Enabled dinput, xinput and winhybrid modules for
Windows SDL builds, and enabled background input for dinput and xinput
(and by extension winhybrid) modules. Also fixed some COM and X11
resource leaks.
osd/modules/input/input_sdl.cpp: Flipped SDL mouse button order to match
Windows, and exposed vertical and horizontal scroll as Z and rZ axes.
Moved SDL UI event handling out of input devices into OSD object.
osd/modules/input_rawinput.cpp: Changed lightgun Z axis token so it's
correctly identified as a relative axis (it maps to the scroll wheel
equivalent).
osd: Added an option to choose the network provider module. Mostly
useful if you build with both TUN/TAP and pcap support included, or if
you want to disable emulated networking completely.
emu/input.cpp: Use a better strategy for assembling input code names
that uses fewer temporary strings and doesn't require use of the
non-Unicode-aware space trimming function (fixes MT08552).
osd/modules/input_dinput.cpp: Improved polling logic.
osd: Made various parts of the input code less dependent on concrete emu
objects, and reduced inappropriately passing around the machine object.
Made input modules less dependent on OSD implementation. Encapsulated
some stuff and got rid of some vestigial newui and SDL1 support code.
Cleaned up some interfaces. Moved OSD options classes to their own
files.
Prepare to remove main.h from emu.h - it's mostly used to get the
application name, which the vast majority of emulated devices don't need
to do.

ui/analogipt.cpp: Fixed bar graph display for fields with ranges
that wrap through zero.
emu/inputdev.cpp: Separateed analog axis deadzone and switch threshold
settings, reduced default deadzone, and fixed a potential division by
zero if the deadzone and saturation settings are equal.
emu/ioport.cpp: Fixed behaviour of absolute analog fields where range
passes through zero - it previously only worked for specific
combinations of mask, minimum and default. Removed a workaround from
universal/getaway.cpp that is no longer necessary.
emu/input.cpp: Fixed unintuitive behaviour when an absolute field is
assigned an OR combination of a relative control folled by an absolute
control (e.g. Mouse X or Joy 1 LSX). Also fixed reading axis input
sequences where an axis code is followed by a switch code (these can
only be produced by manually editing configuration files, not through
MAME's UI), and fixed the returned type when multiple relative axes sum
to zero.
osd/modules/input_dinput.cpp: Fixed hat switches being stuck in up
position when input is suspended in the background
taito/taitoio_yoke.cpp: Give throttle control a distinct type, and don't
auto-centre.
osd: Added option to select MIDI provider module (currently only
PortMidi and the dummy module are available). Also put various things
in namespaces, and fixed builds including SDL sound module with native
Windows OSD.
emu/validity.cpp: Added check to catch I/O port fields using UI input
types.
emu/inpttype.ipp: Renamed inputs that were causing confusion. "Bill"
and "Track" were causing confusion for translators and hence likely
causing confusion for many users, especially those who are not native
English speakers. "Track" as an abbreviation for "Trackball" was
frequently being mistranslated, e.g. in the sense of a CD track
selection button or even in the sense of a railway track. There's no
reason to abbreviate it. "Bill" in the US English sense as a banknote
is too ambiguous and was causing confusion for translators. It's better
to use the less ambiguous "Banknote". Corrected Greek translations of
"Trackball".

Also reworked calculation of menu geometry in general, and limited width
of left panel on system/software selection menus.
Fixes images in the right panel and icons on the system/software
selection menus not being scaled correctly when the window is resized
(MT08539 is an example of this).
Fixes bad font size selection at low resolutions when using bitmap fonts
like uismall.bdf (GitHub #7105).
Fixes collapse/expand arrows on left/right panels of system/softwre
selection menus getting bigger if the window is made narrower.

Removed the "default" state for the image tab where it would show
different things for different types of machine - it just confused
users.
Remember the selected tab and image in the right panel. State for
system selection menu is remembered across sessions. Last used state
for software selection menus is remembered across sessions. Within a
session, state is remembered separately for recently selected machines,
similarly to the way filter selection is remembered.
Fixed some focus order issues in the software selection menu.
