* formats, osd, util: Started refactoring file I/O stuff. (#8456) Vas Crabb2021-08-221-5/+5
| | | | | | | | | Added more modern generic I/O interfaces with implementation backed by stdio, osd_file and core_file, replacing io_generic. Also replaced core_file's build-in zlib compression with a filter. unzip.cpp, un7z.cpp: Added option to supply abstract I/O interface rather than filename. Converted osd_file, core_file, archive_file, chd_file and device_image_interface to use std::error_condition rather than their own error enums. Allow mounting TI-99 RPK from inside archives.

* render.h, rendlay.h: Dependency refactoring AJR2021-01-041-0/+1
| | | | | - render.h: Split out layout class declarations into rendlay.h, with some adjustments for the resulting incomplete types (std::reference_wrapper unfortunately does not allow these by C++17 rules) - rendlay.h: Move old header contents to layout/generic.h

* Fairly significant overhaul of Lua engine and some cleanup. Vas Crabb2020-11-251-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The things that were previously called device iterators are not iterators in the C++ sense of the word. This is confusing for newcomers. These have been renamed to be device enumerators. Several Lua methods and properties that previously returned tables now return lightweight wrappers for the underlying objects. This means creating them is a lot faster, but you can't modify them, and the performance characteristics of different operations varies. The render manager's target list uses 1-based indexing to be more like idiomatic Lua. It's now possible to create a device enumerator on any device, and then get subdevices (or sibling devices) using a relative tag. Much more render/layout functionality has been exposed to Lua. Layout scripts now have access to the layout file and can directly set the state of an item with no bindings, or register callbacks to obtain state. Some things that were previously methods are now read-only properties. Layout files are no longer required to supply a "name". This was problematic because the same layout file could be loaded for multiple instances of the same device, and each instance of the layout file should use the correct inputs (and in the future outputs) for the device instance it's associated with. This should also fix video output with MSVC builds by avoiding delegates that return things that don't fit in a register.
* Enable GCC implicit fallthrough warning. Vas Crabb2020-11-151-0/+1
| | | | | | I've guessed whether break or [[fallthrough]] is appropriate. In cases where it looked particularly suspicious, I added a FIXME comment. All of these changes should be reviewed by someone familiar with the code.
* Various improvements to image file handling: Vas Crabb2020-10-081-7/+19
| | | | | | | | | | | | | | | | | | | | | | | | Moved MS DIB parser out of ICO file reader and made it available for artwork and layout images. Added more efficient I/O and better error checking for JPEG file loading (MAME will no longer exit immediately on a bad JPEG file). Made caller responsible for opening files for loading images, to avoid decompressing images used in ZIP/7z artwork multiple times. Added support for JPEG and Windows DIB to picture_image_device. Added support for SVG image files in external artwork. Added support for using I/O port value for animation state and masking animation state values. Made bounds elements more flexible in layouts. Reworked headers to reduce dependencies. Updated layout file format documentation.

* Got rid of global_alloc/global_free. Vas Crabb2020-10-031-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | The global_alloc/global_free functions have outlived their usefulness. They don't allow consistently overriding the default memory allocation behaviour because they aren't used consistently, and we don't have standard library allocator wrappers for them that we'd need to use them consistently with all the standard library containers we're using. If you need to change the default allocator behaviour, you can override the new/delete operators, and there are ways to get more fine-grained control that way. We're already doing that to pre-fill memory in debug builds. Code was already starting to depend on global_alloc/global_free wrapping new/delete. For example some parts of the code (including the UI and Windows debugger) was putting the result of global_alloc in a std::unique_ptr wrappers without custom deleters, and the SPU sound device was assuming it could use global_free to release memory allocated with operator new. There was also code misunderstanding the behaviour of global_alloc, for example the GROM port cartridge code was checking for nullptr when a failure will actually throw std::bad_alloc. As well as substituting new/delete, I've made several things use smart pointers to reduce the chance of leaks, and fixed a couple of leaks, too.
* -Got rid of most of the remaining problematic uses of make_unique_clear. Vas Crabb2020-09-301-1/+1
| | | | -sound/discrete.cpp: Use C++ std::vector and range-based for.
* Cleaned up bitmap API. Vas Crabb2020-09-271-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Made const-qualified pixel accessors (pix, pixt, raw_pixptr) return const-qualified references/pointers to pixesl, and added non-const versions. This makes bitmap more like standard library containers where const protects the content as well as the dimensions. Made the templated pixt accessor protected - having it public makes it too easy to inadvertently get a pointer to the wrong location. Removed the pix(8|16|32|64) accessors from the specific bitmaps. You could only use the "correct" one anyway, and having the "incorrect" ones available prevented explicit instantiations of the class template because the static assertions would fail. You can still see the pixel type in the bitmap class names, and you can't assign the result of &pix(y, x) to the wrong kind of pointer without a cast. Added fill member functions to the specific bitmap template, and added a explicit instantiations. This allows the bitmap size check to be skipped on most bitmap fills, although the clipping check is still there. Also fixed a couple of places that were trying to fill an indexed 16-bit bitmap with rgb_t::black() exposed by this (replaced with zero to get the same net effect). The explicit template instantiations in the .cpp file mean the compiler can inline the function if necessary, but don't need to generate a local out-of-line body if it chooses not to. Extended the size of the fill value parameter in the base bitmap class to 64 bits so it works correctly for 64-bit bitmaps. Fixed places where IE15 and VGM visualiser weren't accounting for row bytes potentially being larger than width. Fixed an off-by-one in an HP-DIO card where it was treating the Topcat cursor right edge as exclusive. Updated everything to work with the API changes, reduced the scope of many variables, added more const, and replaced a few fill/copy loops with stuff from <algorithm>.
* -util/xmlfile: Escape attribute and element content. Vas Crabb2020-09-061-1/+1
| | | | | | | | | | | | | | | | | | | | The previous behaviour was unintuitive - parsing an XML file and writing it out immediately would produce invalid XML if the file contained any characters that needed escaping. It makes far more sense to escape on writing rather than expecting the user to escape input. -Add preliminary support for visibility toggles to artwork system. This allows the user to show/hide related elements in a view, with nesting. The view can specify whether elements are shown or hidden by default. Settings are saved per host window/screen per view. There is no way to set the initial visibility state on the command line. Legacy "Space Invaders cabinet model" layers are mapped onto visibility toggles. This is not stable yet. In particular, the XML element/attribute names have not been finalised. The new features have not been added to complay.py to prevent them from being used before they're finalised.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | significant change, so please pay attention. The core changes are: * Short name, full name and source file are no longer members of device_t, they are part of the device type * MACHINE_COFIG_START no longer needs a driver class * MACHINE_CONFIG_DERIVED_CLASS is no longer necessary * Specify the state class you want in the GAME/COMP/CONS line * The compiler will work out the base class where the driver init member is declared * There is one static device type object per driver rather than one per machine configuration Use DECLARE_DEVICE_TYPE or DECLARE_DEVICE_TYPE_NS to declare device type. * DECLARE_DEVICE_TYPE forward-declares teh device type and class, and declares extern object finders. * DECLARE_DEVICE_TYPE_NS is for devices classes in namespaces - it doesn't forward-declare the device type. Use DEFINE_DEVICE_TYPE or DEFINE_DEVICE_TYPE_NS to define device types. * These macros declare storage for the static data, and instantiate the device type and device finder templates. The rest of the changes are mostly just moving stuff out of headers that shouldn't be there, renaming stuff for consistency, and scoping stuff down where appropriate. Things I've actually messed with substantially: * More descriptive names for a lot of devices * Untangled the fantasy sound from the driver state, which necessitates breaking up sound/flip writes * Changed DECO BSMT2000 ready callback into a device delegate * Untangled Microprose 3D noise from driver state * Used object finders for CoCo multipak, KC85 D002, and Irem sound subdevices * Started to get TI-99 stuff out of the TI-990 directory and arrange bus devices properly * Started to break out common parts of Samsung ARM SoC devices * Turned some of FM, SID, SCSP DSP, EPIC12 and Voodoo cores into something resmbling C++ * Tried to make Z180 table allocation/setup a bit safer * Converted generic keyboard/terminal to not use WRITE8 - space/offset aren't relevant * Dynamically allocate generic terminal buffer so derived devices (e.g. teleprinter) can specify size * Imporved encapsulation of Z80DART channels * Refactored the SPC7110 bit table generator loop to make it more readable * Added wrappers for SNES PPU operations so members can be made protected * Factored out some boilerplate for YM chips with PSG * toaplan2 gfx * stic/intv resolution * Video System video * Out Run/Y-board sprite alignment * GIC video hookup * Amstrad CPC ROM box members * IQ151 ROM cart region * MSX cart IRQ callback resolution time * SMS passthrough control devices starting subslots I've smoke-tested several drivers, but I've probably missed something. Things I've missed will likely blow up spectacularly with failure to bind errors and the like. Let me know if there's more subtle breakage (could have happened in FM or Voodoo). And can everyone please, please try to keep stuff clean. In particular, please stop polluting the global namespace. Keep things out of headers that don't need to be there, and use things that can be scoped down rather than macros. It feels like an uphill battle trying to get this stuff under control while more of it's added.
