Ports with -DNONSTANDARD_PORT need this too.

COMMON: Add Span to common library
|
|
|
|
|
|
Now it is possible to enforce checking by specifying level -1,
that is, debug level 11 will not turn it on.
|
|
|
|
Implicitly generated constructors can be used instead of explicit
constructors, which reduces the amount of necessary boilerplate.
Long lists of identical typedefs to the superclass are now defined
using a macro.
data() const now returns a pointer to data that matches the
value_type of the data, instead of forcing the data to be const.
This better matches the intent of the Span class, which provides
a view into data, rather than being a container that holds data.
|
|
The data access helpers as written are effectively little-endian
when reading from spans with value_types larger than the size of
the requested data (e.g. more than 1 byte for getting a char,
more than 2 bytes for getting a uint16, etc.). For now, restrict
use of these methods at compile time until someone actually needs
to read memory that way.

Span is roughly modelled on the GSL span<T> type, and is intended
to replace direct access to raw pointers -- especially pointers
that are passed to functions along with a separate size
parameter. It provides low-cost bounds-checked reads and writes,
as well as convenience functions for reading common values
(integers of varying endianness, strings, etc.). While similar to
MemoryReadStream in purpose, Span is superior in cases where
memory is writable, where memory is accessed randomly rather than
sequentially, or where any invalid access should be treated as an
unrecoverable error. It should also be more efficient than a
MemoryReadStream because it is implemented using CRTP, so there is
no runtime overhead from dynamic dispatch.
NamedSpan is an extension of Span which provides enhanced
debugging information when out-of-bounds memory accesses occur.
It allows programmers to name the memory span at construction time,
and it also tracks the offsets of subspans so that the absolute
byte offset of the original memory can be provided in the error
message if an out-of-bounds access occurs.
SpanOwner is similar to ScopedPtr but has awareness of the design
of Span objects, so allows the memory pointed to by the Span object
inside the SpanOwner to be freed when the SpanOwner is freed
without requiring holding a separate pointer to the start of
memory. It also provides some copy semantics, so unlike a ScopedPtr,
SpanOwners can be held by objects in movable containers like
Common::Array -- but note that because there are no move semantics
in C++98, this means that a new, complete memory copy of the
pointed-to data will be created, rather than just a new Span
pointing to the same block of memory, when a container holding a
SpanOwner expands.

Type traits allow conditional selection and manipulation of types
during compilation.
|
|
This API is intended for use in cases where C strings come
from untrusted sources like game files, where malformed data
missing the null terminator would cause strlen to read out of
bounds.

The emitted warning is "ISO C++98 does not support the ‘%lg’ gnu_printf
format [-Wformat=]".
Though "%lg" is required for *scanf functions to indicate the field
size, it is not required for *printf functions which use "%g" instead.

Registering the OSDMessageQueue instance as an event source is now done
right after the event manager is initialised. This ensures that it is created in a
sensible place and not for example in another thread). Also registering the
event source is moved to a separate function instead of being in the constructor
to remove any issue in case some code tries to display a OSD Message very early
on (the instance would be created then, but it would be registered as an event
source later).
|
|
This class can be used to get messages to display on the OSD from
any thread. Those messages are then passed to the backend in the
graphic thread.

COMMON: Add Atari 8-bit platform

MemoryReadWriteStream now returns int32, not uint32. It actually doesn't
ever return -1 to indicate that an error occured, so uint32 was a better
choice, but that's what is used in WriteStream base class now.
That method is abstract, so that's also why OutSaveFile had to override
it.
|
|
Commit adds kFeatureClipboardSupport. hasTextInClipboard() and
getTextFromClipboard().
OSystem_SDL has this feature if SDL2 is used.
EditableWidget and StorageWizardDialog use g_system to access clipboard
now.

I knew there were some, but I wanted to fix them once, instead of doing
it all the time.

Searches for a substring in the string and replaces it with the other
string.
|
|
Tested that on actual unix system and found out a few minor bugs related
to paths.
|
|
Mostly on format string
|
|
It had to become a proxy class in order to do that.
finalize() starts the saves sync.
|
|
Instead of all these atoull() I've added everywhere.
|
|
MetaEngines don't get "locked" files in the list, so won't try to open
these.
Save/Load dialog updates save list every time SavesSyncRequest tells it
to.

So one can erase everything from OSD and then blit something on it.
