The current Portuguese entry is Brazilian dialect, so modifying the
description and adding an entry for European Portuguese.
This is required to deal with bug Trac #10791.
This fixes a crash due to concurrent access to the global MemoryPool
used by the String class when String objects are used simultaneously
from several threads (as is for example the case when enabling the
cloud features).
See bug #10524: Thread safety issue with MemoryPool
Some feature, such as mutexes, are only available once the backend
has been initialized. This new function can be used to avoid using
those feature too early or too late.
Scaling works correctly with the Windows variant, which uses AVI files,
but the DOS variant uses Robot videos, and the way scaling is done
there is different, and is not working yet with KQ7 DOS. Nonetheless,
both versions are included in the game, so it's not a major issue.
A new internal table has been added so that no if checks need to
be performed for the at() lookup.
The old table can still be accessed using getTable or atLegacy().
at() and atLegacy() return the same values, but at() is faster.
When the constructor for the cos/sin table was changed from
number of bits to number of points all usages thoughout the
code should of been changed, but this was missed in RDFT and DCT.
Fixes Trac#10683.
Previously, the cos/sin table had to be a power of 2, but there
are many use cases where the number of points is not necessarily
a power of 2 so this change the constructor so it now takes
in the number of points rather than the number of points as the
exponent of a power of 2.
The restriction is that the size must be divisible by 4.
When erasing and inserting many items this caused the hashmap capacity
to grow more than it should which resulted in performances issues (and
possibly memory issues as well). The issue was reported on IRC today
with the wintermute engine.
The cos/sin table class now has an at() function for indexing
safely into its internal array.
This allows the checking and computing of the correct
indexes to be done internally.
The indexing in allows cos/sine of 0 to 2pi to be
obtained.
The values returned by getTable are the same as before.
Comments that describe the values that the table
contains has been modified to line up with what
the code is doing.
This commit introduces the following changes:
1. Graphics::loadThumbnail()
Now returns a boolean and takes a new argument skipThumbnail which
defaults to false. In case of true, loadThumbnail() reads past the
thumbnail data in the input stream instead of actually loading the
thumbnail. This simplifies savegame handling where, up until now,
many engines always read the whole savegame metadata (including
the thumbnail) and then threw away the thumbnail when not needed
(which is in almost all cases, the most common exception being
MetaEngine::querySaveMetaInfos() which is responsible for loading
savegame metadata for displaying it in the GUI launcher.
2. readSavegameHeader()
Engines which already implement such a method (name varies) now take
a new argument skipThumbnail (default: true) which is passed
through to loadThumbnail(). This means that the default case for
readSavegameHeader() is now _not_ loading the thumbnail from a
savegame and just reading past it. In those cases, e.g.
querySaveMetaInfos(), where we actually are interested in loading
the thumbnail readSavegameHeader() needs to explicitely be called
with skipThumbnail == false.
Engines whose readSavegameHeader() (name varies) already takes an
argument loadThumbnail have been adapted to have a similar
prototype and semantics.
I.e. readSaveHeader(in, loadThumbnail, header) now is
readSaveHeader(in, header, skipThumbnail).
3. Error handling
Engines which previously did not check the return value of
readSavegameHeader() (name varies) now do so ensuring that possibly
broken savegames (be it a broken thumbnail or something else) don't
make it into the GUI launcher list in the first place.
Compilers optimise these back into shifts on architectures where
shifts of negative integers work the same as mul/div, so this
solves the UB without actually causing any performance issue.
Custom deleters of ScopedPtr are not currently fully conforming to
C++11's support for custom deleters in std::unique_ptr for the
sake of simplicity of implementation. Unlike in the standard
library, plain functions and lvalue references are not supported,
nor may custom deleters be passed to the constructor at runtime.
This can be improved in the future, if necessary, by doing what
standard library implementations usually do and creating a Pair
class that uses the Empty Base Optimization idiom to avoid extra
storage overhead of the deleter instance when it is not needed, as
in typical standard library implementations, plus some additional
type traits to support the necessary metaprogramming for the
different type overloads.
This improves the output of static assertions in all compilers,
and prevents problems in MSVC 2015 where the mechanism for
triggering a compilation error in C++98 mode may cause errors when
that compiler builds in release mode.
Fixes Trac#10154.
Normally with SDL, a mouse motion event will be sent after the
system mouse cursor has been moved by a call to
SDL_WarpMouseInWindow, but if the system cursor cannot be moved
(e.g. because the window does not have mouse focus), games still
need to receive these mouse events so they can successfully update
the mouse position internally. Otherwise, games continue to think
the mouse is still in the original position and will continue to
try to perform whatever action is associated with that mouse
position.
Refs Trac#9689.
There is no particular reason why backends that don't need to
calculate screen dimensions in advance should still need to
implement initSizeHint at this point.
Although the previous count-constructor would never make a copy of
a member at runtime, Array<T>::reserve *may* copy-construct, so
the compiler would forbid creation of arrays of NonCopyable objects
even when the array was created only once and then never resized
(and thus never actually tried to perform a copy-construction).
This matches the C++11 std::vector method of the same name, and
replaces usage of taking the address of the first element of an
array by &array[0] or &array.front() or &*array.begin(). The data
method is better than these usages because it can be used even
when the array is empty.
These are additions to match C++11 std::vector common init
patterns, to make Common::Array cover more common use cases where
C-style arrays are currently used (and should not be).
And fix an out of bounds acces when seeking to the end of a video.
Skipping samples is needed even when seeking through silent edits
because a silent stream is queued for those.
Fixes#10219.
To enable the optional content censoring mode, Phant2 looks
for a RESDUK.PAT file, which is normally placed by the game's
installer if the user chose to enable censorship. If the file
exists, the game reads an unlock password out of the file and
asks the user to enter the password when starting a new game to
create an uncensored game, or to click a "less intense" button
to start the game with censoring. The censorship state of the
game is then persisted in the save game file, and installations
with the RESDUK.PAT file need to enter the password again in
order to restore any of the uncensored saves.
Since we do not have an installer that can enable this feature,
add a game option toggle to enable/disable censoring (for the
releases that have the optional censorship mode) instead so the
censored content feature is available for anyone that wants to use
it. This flag is restored from ScummVM whenever a save game is
loaded, so it can be toggled on or off at any point without
needing a separate save game, unlike in the original interpreter.
All users of BitStream were in fact using a specific, hardcoded variant,
so we can hardcode that variant, removing the need for virtual calls,
and enabling inlining.
This allows MemoryReadWriteStream to be passed successfully to
functions that use the SeekableReadStream type so that they can
call the `pos` method, like the DPCMStream class of the VMD
decoder.
This fixes tons of warnings with clang from a recent xcode version on
macOS (and possibly other systems) complaining that an instantiation
of _singleton is required but no definition is available.
Until C++11 (which introduces the z and t length modifiers), there
is no consistent way to print size_t and ptrdiff_t types using
printf formatting across 32-bit, LLP64, and LP64 architectures
without using a cumbersome macro to select the appropriate length
modifier for the target architecture. Since ScummVM engines
currently need to support 32-bit targets, there is no reason at
the moment to support any larger memory sizes in Span anyway.
Span error output is also updated in this commit to reflect that
index values are unsigned.
Fixes erratic speeds in analog pointer motion
Implemented option to set analog/keyboard pointer speed
and control the analog joystick deadzone. The deadzone option appears
only if the build supports analog joystick (via JOY_ANALOG define)
GUIO_NOSPEECHVOLUME can be used for games that allow toggling of
speech but do not provide the ability for users to control speech
volume.
GUIO_LINKMUSICTOSFX and GUI_LINKSPEECHTOSFX can be used for games
that allow control of music, sfx, and speech in combinations, like
games that provide control of digital audio separately from MIDI,
or games that only control all three audio types through a single
volume control.
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.
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).
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.
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.
It has its own GoogleDriveTokenRefresher and knows how to do info().
This commit also contains JSON int -> long long int fix and
CurlJsonRequest '\n' -> ' ' fix.
Can be used with Callback<T> (means it's still type safe). It's used to
pass not only Request id to user's callback, but also a value user
wanted.
void *data field is removed from RequestInfo.
DumpFile::open() with createPath=true create would create the missing
directories from the path before opening a file. Thus, one can easily
create a file and avoid "can't open a file" error.
Knows how to OAuth already.
This commit also adds CloudManager::addStorage(), so OneDriveStorage can
add newly created Storage and CloudManager can save it in the
configuration file.
In this commit CloudManager starts supporting multiple Storage. Now, in
its init() it loads all the Storages and determines the current one.
It now also has save() method. In that method all Storages are saved
with their new saveConfig() method.
CloudManager::save() not called from anywhere, though. The only one
Storage that could be added is DropboxStorage in case you have no
cloud-related config keys or you have no storages connected.
This commit also adds GlobalFunctionCallback, because it was needed in
order to replace plain C pointers to functions (which were used in
Request) into our object-oriented BaseCallback pointers.
These callbacks can call object's methods, not some global C functions.
DropboxStorage::info2() and DropboxStorage::infoMethodCallback()
demonstrate the idea.
Originally, I intended to add Storage API, StorageFile and StorageInfo
stubs. When I tried to implement a simple info() call, I ended up fixing
Request to contain some pointer field and all callbacks to have Request*
parameter. And, now I have to place callback pointer into Request. which
calls another callback.
And, eventually, these "simple" callbacks would again require another
pointer (to some caller class).
This commit adds:
* ConfMan's new "cloud" domain;
* CloudManager's init() method, where it loads keys from "cloud" configs
domain;
* CurlJsonRequest's addHeader() and addPostField() methods;
* temporary Storage's printInfo() method;
* DropboxStorage's implementation of printInfo(), which is using access
token and user id;
* DropboxStorage's loadFromConfig() static method to load access token
and user id from configs and create a Storage instance with those;
* temporary DropboxStorage's authThroughConsole() static method, which
guides user through auth process from the console.
So, in CloudManager's init() implementation ScummVM checks that there is
"current_storage_type" key in "cloud" domain of configs, and loads
corresponding storage if there is such key.
If there is no such key, ScummVM offers user to auth with Dropbox.
That's done through console, and thus it's temporary (it also requires
restarting ScummVM twice and manually editing config.ini file).
Now we can do REST API request by creating CurlJsonRequest and waiting
for it to call our callback. Passed pointer is Common::JSONValue.
This commit also does some minor variable renaming fixes.
Now it is based on MemoryReadWriteStream, which is introduced by this
commit. This stream is using ring buffer and is dynamically increasing
its size when necessary.
This commit introduces Common::CloudManager, which can be accessed from
OSystem.
The backend for this manager is Cloud::Manager (defined in
backends/cloud/manager.h). It should load all users storages from
configs and provide access to current Storage instance. For now it just
creates a new one.
Cloud::Storage (backends/cloud/storage.h) provides an API to interact
with cloud storage, for example, create new directory or sync files.
Right now it's not ready and has only two dummy methods: listDirectory()
and syncSaves().
There is Cloud::Dropbox::DropboxStorage backend
(backends/cloud/dropbox/dropboxstorage.h) for Cloud::Storage. Right now
it implements both listDirectory() and syncSaves() with starting timer
task and handling it by printing out some JSON examples.
This commit also adds CloudThread class, which work() method is called
every second by TimerManager.
Right now it prints JSON examples on the console, so that's why it's
introduced with SimpleJSON library.
Many of our systems currently generate significant amount of debug
output on deeper levels. Now, when your engine is using Debug Channels,
you might want to show that debug information only, which is currently
not possible, as the generic output will be mixed in your output.
Alternative solution would be to implement possibility to specify
per-channel debug levels.
Though it seemed the _wrapped stream should return valid position, it
was always 0. That's why I've added a _pos field, which is updated in
write() and returned in pos().
