Shader compilation now keeps track of the discard key word.
Previously only variables were monitored. But discard, which needs
special treatment in some cases, went unnoticed by the compiler as
discard is not a variable but a flow control.
This commit adds monitoring for discard.
Fixes thread and process handles leak when running and killing project
from editor (caused by a missing CloseHandle call) plus a potential leak
when calling OS_Windows::execute with p_blocking and !r_pipe.
The leak could be easily observed with a Handles counter in Task Manager
(or Performance Monitor) for the Godot editor process.
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
Sorry for the history pollution. I was testing something on this branch
and forgot to reset befor pushing the security update.
This reverts commit 2ef66def46.
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.
