Remove hash symbol in front of opcode error messages in GDScript
The hash symbol creates spurious issue references on GitHub if
the message is posted outside a code block, which means some issues
have a lot more references than originally intended.

clang-format: Disable alignment of operands, too unreliable
Sets `AlignOperands` to `DontAlign`.

`clang-format` developers seem to mostly care about space-based indentation and
every other version of clang-format breaks the bad mismatch of tabs and spaces
that it seems to use for operand alignment. So it's better without, so that it
respects our two-tabs `ContinuationIndentWidth`.

Pedro J. Estébanez 6697e380d9 Fix check for freed object during cast 2021-09-27 19:46:49 +02:00
Pedro J. Estébanez 26edc6cd41 Promote object validity checks to release builds
Extra:
- Optimized the debug-only check about why the object is null to determine if it's because it has been deleted (the RC is enough; no need to check the ObjectDB).
- Because of the previous point. the debugger being attached is not required anymore for giving the "Object was deleted" error; from now, it only matters that it's a debug build.
- `is_instance_valid()` is now trustworthy. It will return `true` if, and only if, the last object assigned to a `Variant` is still alive (and not if a new object happened to be created at the same memory address of the old one).
- Replacements of `instance_validate()` are used where possible `Variant::is_invalid_object()` is introduced to help with that. (GDScript's `is_instance_valid()` is good.)

Pedro J. Estébanez 123d3ef935 Complain if casting a freed object in a debug session
The idea is to give the user a chance to realize a mistake that will cause a crash in a release build (or with no debugger attached).

Pedro J. Estébanez 4ddcdc031b Modernize Mutex
- Based on C++11's `mutex`
- No more need to allocate-deallocate or check for null
- No pointer anymore, just a member variable
- Platform-specific implementations no longer needed
- Simpler for `NO_THREADS`
- `BinaryMutex` added for special cases as the non-recursive version
- `MutexLock` now takes a reference. At this point the cases of null `Mutex`es are rare. If you ever need that, just don't use `MutexLock`.
- `ScopedMutexLock` is dropped and replaced by `MutexLock`, because they were pretty much the same.

Update copyright statements to 2021
Happy new year to the wonderful Godot community!

2020 has been a tough year for most of us personally, but a good year for
Godot development nonetheless with a huge amount of work done towards Godot
4.0 and great improvements backported to the long-lived 3.2 branch.

We've had close to 400 contributors to engine code this year, authoring near
7,000 commit! (And that's only for the `master` branch and for the engine code,
there's a lot more when counting docs, demos and other first-party repos.)

Here's to a great year 2021 for all Godot users 🎆

Pedro J. Estébanez 46fc451b9c Remove useless check in GDScript
The removed check was adding a protection for the case where a `Reference` has not yet got its reference count initialized and a script is called on it. That would cause the object to be released after the call. The removed code was constructing the `Variant` via the `Object` constructor so it didn't deal with the reference count and so the release was prevented.

 However, `Variant` no longer works that way so that check was useless. Now it's just illegal to run GDScript on a Reference whose reference count has not been initialized.

George Marques e360dc9a79 GDScript: Remove self static reference and create one on calls
This is needed because of the new changes to Variant. The reference
counter is increased by adding it to a Variant, which means no GDScript
will be freed (or will be double freed if manually freed somewhere).

Pedro J. Estébanez 64344e6d1d Fix object leaks caused by unfulfilled yields
Now the stack saved in a `GDScriptFunctionState` is cleared as soon as the `yield()` operation is known not to be resumed because either the script, the instance or both are deleted.

This clears problems like leaked objects by eliminating cases of circular references between `GDScriptFunctionState`s preventing them and the objects they refer to in their saved stacks from being released. As an example, this makes using `SceneTreeTimer` safer.

Furthermore, with this change it's now possible to print early warnings about `yield()`s to released script/instances, as now we know they won't be successfully resumed as the condition for that happens. However, this PR doesn't add such messages, to keep the observed behavior the same for the time being.

Also, now a backup of the function name in `GDScriptFunctionState` is used, since the script may not be valid by the time the function name is needed for the resume-after-yield error messages.

ChibiDenDen 9ffa9a6bac Fix constant access in base class through subclass instance
Fixes as issue where a subclass calls a base class method that tries to access a constant from the script.
The original code went through every ower class, and for each owner, went through its inheritance tree.
This seems like the wrong order, the modified code goes to each base class, and for each base class goes through the owner tree.
This is more in line with what the parser does, as the current impelemtation allows an access that the parser does not support.
This change should not negatively affect existing code due to the way the parser works

GDScript: Validate object instance on `is` operation
Avoids crashes on debug mode. Instead it now breaks the execution and
show the error in-editor. Will still crash on release.

Also add a similar check to Marshalls to ensure the debugger doesn't
crash when trying to serialize the invalid instance.

Happy new year to the wonderful Godot community!

We're starting a new decade with a well-established, non-profit, free

pipeline from hundreds of contributors.

Godot will keep getting better, and we're looking forward to all the
games that the community will keep developing and releasing with it.

GDScript: validate instance before accessing it on error
Make sure the instance is valid before trying to access the script in
after an error happened. If the instance is not valid it's possible that
the script is invalid as well.

Mitch Curtis aa8e3e7b0f GDScript: add an optional message parameter to assert()
Before this patch, assert() only took the condition to assert on:

    assert(item_data)

Now, it can optionally take a string that will be printed upon failure:

    assert(item_data, item_name + " has no item data in ItemDatabase")

This makes it easier to immediately see what the issue is by being
able to write informative failure messages.

Thanks to @wiped1 for sharing their patch, upon which this is based.

Keep GDScript functions in stack while yielding
This prevents GDScript functions from leaving the stack too soon when
they are resuming from yield, allowing the ones expecting it to finish
to know the caller.

Helps debugging cases when you use:
`yield(function_which_yields(), "completed")`
since now it shows the call that resumed that function.
