A couple of null appends got typoed to append a '0' character instead.
Removed them here since String already takes care of the null terminator for us.
Fixes exported property modified values lost when creating a placeholder script instance with a failed script compilation
- Object set/get will call PlaceHolderScriptInstance's new fallback set/get methods as a last resort. This way, placeholder script instances can keep the values for storage or until the script is compiled successfuly.
- Script::can_instance() will only return true if a real script instance can be created. Otherwise, in the case of placeholder script instances, it will return false.
- Object::set_script(script) is now in charge of requesting the creation of placeholder script instances. It's no longer Script::instance_create(owner)'s duty.
- PlaceHolderScriptInstance has a new method set_build_failed(bool) to determine whether it should call into its script methods or not.
- Fixed a few problems during reloading of C# scripts.
When a Vector of Vectors gets resized the 'this' pointer of the Vectors
change. This means that the VectorWriteProxy _parent references get
invalidated. Thanks a lot to @ibrahn for finding the root cause of this.
To fix this we now create a pointer to CowData in Vector (which won't
change when the vectors move) and pass that to the write proxy also.
This fixes#20475
Yesterday, when playing around with my network code, I realized there is
a security issue in decode_variant, at least when decoding PoolArrays.
Basically, the size of the PoolArray is encoded in a uint32_t, when
decoding it, that value is cast to int when comparing if the packet is
actually that size causing numbers with MSB=1 to be interpreted as
negative thus always passing the check. That same value though, is used
as uint32_t again to resize the output vector. For this reason, sending
a malformed packet with declared type PoolByteArray and size of 2^31(+x)
causes the engine to try to allocate 2+GB of pool memory, causing the
engine to crash.
(cherry picked from commit 5262d1bbcc)
- Refactored all builder (make_*) functions into separate Python modules along to the build tree
- Introduced utility function to wrap all invocations on Windows, but does not change it elsewhere
- Introduced stub to use the builders module as a stand alone script and invoke a selected function
There is a problem with file handles related to writing generated content (*.gen.h and *.gen.cpp)
on Windows, which randomly causes a SHARING VIOLATION error to the compiler resulting in flaky
builds. Running all such content generators in a new subprocess instead of directly inside the
build script works around the issue.
Yes, I tried the multiprocessing module. It did not work due to conflict with SCons on cPickle.
Suggested workaround did not fully work either.
Using the run_in_subprocess wrapper on osx and x11 platforms as well for consistency. In case of
running a cross-compilation on Windows they would still be used, but likely it will not happen
in practice. What counts is that the build itself is running on which platform, not the target
platform.
Some generated files are written directly in an SConstruct or SCsub file, before the parallel build starts. They don't need to be written in a subprocess, apparently, so I left them as is.
This commit makes operator[] on Vector const and adds a write proxy to it. From
now on writes to Vectors need to happen through the .write proxy. So for
instance:
Vector<int> vec;
vec.push_back(10);
std::cout << vec[0] << std::endl;
vec.write[0] = 20;
Failing to use the .write proxy will cause a compilation error.
In addition COWable datatypes can now embed a CowData pointer to their data.
This means that String, CharString, and VMap no longer use or derive from
Vector.
_ALWAYS_INLINE_ and _FORCE_INLINE_ are now equivalent for debug and non-debug
builds. This is a lot faster for Vector in the editor and while running tests.
The reason why this difference used to exist is because force-inlined methods
used to give a bad debugging experience. After extensive testing with modern
compilers this is no longer the case.
-Project/Editor settings now show tooltips properly
-Settings thar require restart now will show a restart warning
-Video driver is now visible all the time, can be changed easily
-Added function to request current video driver
Same as erase, but it returns a boolean value indicating whether the pair was erased or not.
This method should be removed during the next compatibility breakage, and 'Dictionary::erase(key)' should be changed to return a boolean.
Previous problems include failure to remove the splitter from the last
element found and a possible infinite loop dealing with multi-character
splitter strings.
Before this change, missing User-Agent and Accept headers were automatically
added on all platforms. Setting the User-Agent header forces the browser to
do a CORS preflight (see 1) which fails if the HTTP endpoint is not
configured appropriate. It's not neccesary to set either header as the
browser sets them and so this commit disables that functionality on the JS
target.

Initialized the PID to -2, which will be the value returns in blocking-
mode where the PID is not available. (-1 was already taken to signify an
execution failure).
OS::execute will now properly return a non-OK error code when it fails
to execute the target file.
The documentation was rewritten to be very clear about the differences
between blocking and non-blocking mode.
Fixes#19056.
Implements the same heuristic as Curl (and web browsers): if no `Content-Length`, no `Connection: keep-alive` and no chunked transfer encoding, assume th rest of the data until EOF is the body, gracefully setting the HTTP client back to the disconnected state.
Theoretically, this is not compliant with HTTP 1.1, by which `keep-alive` is the default, but in practice, an explicit header is sent by servers.
Adds following functions to the Engine singleton:
get_author_info - names of Godot authors
get_copyright_info - detailed source copyright get_license_info
get_donor_info - donor names
get_license_info - full text of licenses used, indexed by license names
get_license_text - the text of the Godot Expat license
The code had a subtle signed/unsigned bug -
```cpp
if( signed - unsigned < 0)
// signed - unsigned is unsigned in c++, so
if( unsigned < 0)
// and thus the if block will never be executed
```
Thus all the following code would be ran, including unnecessary retries
of compacting the pool.
- Adds q/quit option to console debugging
- Adds options (variable_prefix)
- Breaks into debugger with Ctrl-C in local debug mode (Unix/Windows)
- Added option to list all breakpoints
- Fixes add/remove breakpoint bug (invalid path parsing)
- Minor cleanup
- Tool scripts will be executed and can be accessed by plugins.
- Other script languages can implement add/remove_named_global_constant
to make use of this functionality.
If at the time of the _GLOBAL_DEF call a setting itself was unknown,
the function would always return the supplied default value instead of
checking for overrides. This commit changes that, lookup now always
happens which correctly takes overrides into account.
I had a situation coming from godot-python where the caller of
Variant::get_call_error_text() passed null for `p_argptrs`. In
addition to fixing that in the caller, seems like good practice to
defend against that situation in the callee to prevent a crash.
So this patch just substitutes some semi-useful text for the source
type name and keeps going so the user's actual error gets emitted.
Now generating mouse events from touch is optional (on by default) and it's performed by `InputDefault` instead of having each OS abstraction doing it. (*)
The translation algorithm waits for a touch index to be pressed and tracks it translating its events to mouse events until it is raised, while ignoring other pointers.
Furthermore, to avoid an stuck "touch mouse", since not all platforms may report touches raised when the window is unfocused, it checks if touches are still down by the time it's focused again and if so it resets the state of the emulated mouse.
*: In the case of Windows, since it already provides touch-to-mouse translation by itself, "echo" mouse events are filtered out to have it working like the rest.
On X11 a little hack has been needed to avoid a case of a spurious mouse motion event that is generated during touch interaction.
Plus: Improve/fix tracking of current mouse position.
** Summary of changes to settings: **
- `display/window/handheld/emulate_touchscreen` becomes `input/pointing_devices/emulate_touch_from_mouse`
- New setting: `input/pointing_devices/emulate_mouse_from_touch`
Fixes reported logically dead codes by Coverity
* image.cpp: Doesn't really need any modification. But to remove the bug
report then we have to move the MAX call away from the for loop
statement.
* rasterizer_gles3.cpp: Removes unnecessary elif condition since it is
checked earlier in the function
* collada.cpp: If stamement never reached due to macro ERR_CONTINUE does
the same.
* navigation_mesh.cpp: Variables should always be null - however, also
checked for the very same condition in their function call. Leaving this
for review (whether the function call is necessary or not)
* path_editor_plugin.cpp: If cancel is true, then it should restore the
edited value to the original provided.
http://docs.godotengine.org/en/3.0/classes/class_editorspatialgizmo.html#class-editorspatialgizmo-commit-handle
* spatial_editor_gizmos.cpp: the very condition of i >= 3 is
predetermined in the if case right before it. Thus case 1 is always '1'
and case 2 is always '-1'
* grid_map_editor.cpp: Same as above in spatial_editor_gizmos.cpp
* voxel_light_baker.cpp: Same as above in spatial_editor_gizmos.cpp
* visual_server.cpp: Same as above in spatial_editor_gizmos.cpp
* visual_script_expression.cpp: char '-' is already true in the switch
case mechanism. Thus it can never reach to default case.
* particles.cpp: Case 'PARAM_MAX' is unreachable due to index checking
right before the switch execution.
* shader_language.cpp: Invalid index is handled in switch default case.

Fixes the "always false problem" in TODO comment.
Fixes most current reports on Coverity Scan of uninitialized scalar
variable (CWE-457): https://cwe.mitre.org/data/definitions/457.html
These happen most of the time (in our code) when instanciating structs
without a constructor (or with an incomplete one), and later returning
the instance. This is sometimes intended though, as some parameters are
only used in some situations and should not be double-initialized for
performance reasons (e.g. `constant` in ShaderLanguage::Token).
- StringName::StringName(const StringName &p_name)
Non-static class member _data is not initialized in this constructor nor in any functions that it calls.
- StringName::_Data()
Non-static class member idx is not initialized in this constructor nor in any functions that it calls.
- String::num_uint64(...)
This less-than-zero comparison of an unsigned value is never true. n % base < 0UL.
- String::hex_to_int(...) and String::hex_to_int64(...)
Execution cannot reach this statement (deadcode)
