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.)
This seems to be a pretty old bug, older then originally reported (at
least under certain circumstances).
The IP singleton uses a resolve queue so developers can queue hostnames
for resolution in a separate while keeping the main thread unlocked
(address-resolution OS functions are blocking, and could block for a long
time in case of network disruption).
In most places though, the address resolution function was called with
the mutex locked, causing other functions (querying status, queueing
another hostname, ecc) to block until that resolution ended.
This commit ensures that all calls to OS address resolution are done
with the mutex unlocked.

Variants like dictionaries and arrays can have cyclic references, which
caused `encode_variant` to run an infinite recursion.
Instead of keeping a stack and looking for cyclic references which would
make serialization slower, this commit adds a `MAX_RECURSION_DEPTH`
constant to Variant, and have `encode_variant` keep track of the current
recursion depth, bailing when it's too high since this likely means a
cyclic reference has been encountered.

Removes the error message when the network peer is not valid and returns false instead.
This makes it simpler to make games that are both on/offline by replacing server checks of
'''
if is_instance_valid(get_tree().network_peer) and get_tree().is_network_server():
# Do server things
'''
with
'''
if get_tree().is_network_server():
# Do server things
'''
Requires no changes to the docs because both the MultiplayerAPI and SceneTree docs don't mention the error.
(cherry picked from commit 74379b15ff)
Add two new functions to the IP class that returns all addresses/aliases associated with a given address.
This is a cherry-pick merge from 010a3433df which was merged in 2.1, and has been updated to build with the latest code.
This merge adds two new methods IP.resolve_hostname_addresses and IP.get_resolve_item_addresses that returns a List of all addresses returned from the DNS request.
The error check was added for `FileAccessUnix` but it's not an error when both
`p_src` and `p_length` are zero.
Added correct error checks to all implementations to prevent the actual
erroneous case: `p_src` is nullptr but `p_length > 0` (risk of null pointer
indexing).
Fixes#33564.
(cherry picked from commit 01d5c463be)
* Add support for decimal numeric entities to String::xml_unescape
* Add more error checks to String::xml_unescape
* Refactor XMLParser to use String::xml_unescape instead of an internal
implementation
This changes the types of a big number of variables.
General rules:
- Using `uint64_t` in general. We also considered `int64_t` but eventually
settled on keeping it unsigned, which is also closer to what one would expect
with `size_t`/`off_t`.
- We only keep `int64_t` for `seek_end` (takes a negative offset from the end)
and for the `Variant` bindings, since `Variant::INT` is `int64_t`. This means
we only need to guard against passing negative values in `core_bind.cpp`.
- Using `uint32_t` integers for concepts not needing such a huge range, like
pages, blocks, etc.
In addition:
- Improve usage of integer types in some related places; namely, `DirAccess`,
core binds.
Note:
- On Windows, `_ftelli64` reports invalid values when using 32-bit MinGW with
version < 8.0. This was an upstream bug fixed in 8.0. It breaks support for
big files on 32-bit Windows builds made with that toolchain. We might add a
workaround.
Fixes#44363.

There's still some fishy recursive relationship between `load_interactive` and
`load` which needs to be investigated here, but this patch solves the crash
when returning an error code in user-defined `load`.
Fixes#48463.
We've been using standard C library functions `memcpy`/`memset` for these since
2016 with 67f65f6639.
There was still the possibility for third-party platform ports to override the
definitions with a custom header, but this doesn't seem useful anymore.
Backport of #48239.
The problem happened because `poll` assumed that when the SSL flag was
true, the `connection` would be a subclass of StreamPeerSSL. However
that invariant could be broken by calling HTTPClient::set_connection
with a `connection` that is not a subclass of StreamPeerSSL.
Fixes#46138

- Based on C++11's `atomic`
- Reworked `SafeRefCount` (based on the rewrite by @hpvb)
- Replaced free atomic functions by the new `SafeNumeric<T>`
- Replaced wrong cases of `volatile` by the new `SafeFlag`
- Platform-specific implementations no longer needed

- Based on C++11's `thread` and `thread_local`
- No more need to allocate-deallocate or check for null
- No pointer anymore, just a member variable
- Platform-specific implementations no longer needed (except for the few cases of non-portable functions)
- Simpler for `NO_THREADS`
- Thread ids are now the same across platforms (main is 1; others follow)
- Based on C++11's `mutex` and `condition_variable`
- 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`
- 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.
