Main:
- It's now implemented thanks to `<mutex>`. No more platform-specific implementations.
- `BinaryMutex` (non-recursive) is added, as an alternative for special cases.
- Doesn't need allocation/deallocation anymore. It can live in the stack and be part of other classes.
- Because of that, it's methods are now `const` and the inner mutex is `mutable` so it can be easily used in `const` contexts.
- A no-op implementation is provided if `NO_THREADS` is defined. No more need to add `#ifdef NO_THREADS` just for this.
- `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`.
- Thread-safe utilities are therefore simpler now.
Misc.:
- `ScopedMutexLock` is dropped and replaced by `MutexLock`, because they were pretty much the same.
- Every case of lock, do-something, unlock is replaced by `MutexLock` (complex cases where it's not straightfoward are kept as as explicit lock and unlock).
- `ShaderRD` contained an `std::mutex`, which has been replaced by `Mutex`.
- Renames PackedIntArray to PackedInt32Array.
- Renames PackedFloatArray to PackedFloat32Array.
- Adds PackedInt64Array and PackedFloat64Array.
- Renames Variant::REAL to Variant::FLOAT for consistency.
Packed arrays are for storing large amount of data and creating stuff like
meshes, buffers. textures, etc. Forcing them to be 64 is a huge waste of
memory. That said, many users requested the ability to have 64 bits packed
arrays for their games, so this is just an optional added type.
For Variant, the float datatype is always 64 bits, and exposed as `float`.
We still have `real_t` which is the datatype that can change from 32 to 64
bits depending on a compile flag (not entirely working right now, but that's
the idea). It affects math related datatypes and code only.
Neither Variant nor PackedArray make use of real_t, which is only intended
for math precision, so the term is removed from there to keep only float.
This attribute is now part of the standard we target so we no longer
need compiler-specific hacks.
Also enables -Wimplicit-fallthrough for Clang now that we can properly
support it. It's already on by default for GCC's -Wextra.
Fixes new warnings raised by Clang's -Wimplicit-fallthrough.
WARNING: Requires C++17 'guaranteed copy elision' to fix ambiguous
operator problems in Variant.
This was added for this commit (and future C++17 uses) in #36457.
UDP sockets can be "connected" to filter packets from a specific source.
In case of a bound socket (e.g. server), a new socket can be created on
the same address/port that will receive all packets that are not
filtered by a more specific socket (e.g. the previously connect socket).
This way, a UDPServer can listen to new packets, and return a new
PacketPeerUDP when receiving one, knowing that is a "new client".
It was added for 3.2 in #27485 to preserve backwards compatibility,
but we can now remove it.
It is still needed in MultiplayerAPI as it's the only way to control
it for the internal put_var calls.
- Now is sent the method ID rather the full function name.
- The passed IDs (Node and Method) are compressed so to use less possible space.
- The variant (INT and BOOL) is now encoded and compressed so to use much less data.
- Optimized RPCMode retrieval for GDScript functions.
- Added checksum to assert the methods are the same across peers.
This work has been kindly sponsored by IMVU.
Used to allocate in stack (via alloca) which causes crashes when trying
to encode big variables.
The buffer grows as needed up to `encode_buffer_max_size` (which is
8MiB by default) and always in power of 2.
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.
Unify pack file version and magic to avoid hardcoded literals.
`version.py` now always includes `patch` even for the first release in
a new stable branch (e.g. 3.2). The public name stays without the patch
number, but `Engine.get_version_info()` already included `patch == 0`,
and we can remove some extra handling of undefined `VERSION_PATCH` this
way.

Happy new year to the wonderful Godot community!
We're starting a new decade with a well-established, non-profit, free
and open source game engine, and tons of further improvements in the
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.
The calculation used to be wrong when exactly at a power of 2.
`nearest_shift` always return the "next" power of 2
`nearest_shift(4) == 3 # 2^3 = 8`.
On the other hand `next_power_of_2` returns the exact value if that
value is a power of 2 (i.e. `next_power_of_2(4) == 4`).
I.e. :
```
WARN_PRINT(itos(next_power_of_2(4)) + " " + itos(1 << nearest_shift(4)));
// WARNING: ... : 4 8
```
Is this by design?
Near matching was not implemented like in TranslationServer, so a
resource remapped for 'ru' (but not 'ru_RU') would not be used as
fallback if the system locale was 'ru_RU'.
Fixes#34058.
This allows setting the `read_chunk_size` of the internal HTTPClient.
This is important to reduce the allocation overhead and number of file
writes when downloading large files, allowing for better download speed.
connect_to_stream now accepts optional parameter to specify which
certificates to trust.
Implement accept_stream (SSL server) with key/cert parameters to specify
the RSA key and X509 certificate resources.
The last remaining ERR_EXPLAIN call is in FreeType code and makes sense as is
(conditionally defines the error message).
There are a few ERR_EXPLAINC calls for C-strings where String is not included
which can stay as is to avoid adding additional _MSGC macros just for that.
Part of #31244.
Condensed some if and ERR statements. Added dots to end of error messages
Couldn't figure out EXPLAINC. These files gave me trouble: core/error_macros.h, core/io/file_access_buffered_fa.h (where is it?),
core/os/memory.cpp,
drivers/png/png_driver_common.cpp,
drivers/xaudio2/audio_driver_xaudio2.cpp (where is it?)
Default timeout is 30 seconds (i.e. after 30 seconds of calling
connect_to_host if the TCP peer is not connected the connection will
error out).
This value can be configured in project settings:
`network/limits/tcp/connect_timeout_seconds`
For clarity, assign-to-release idiom for PoolVector::Read/Write
replaced with a function call.
Existing uses replaced (or removed if already handled by scope)
Both client and server are supported on native builds (as usual).
SSL server is still not supported, but will soon be possible with this
new library.
The API stays the same, we just need to work out potential issues due to
this big library switch.
The basic point is as in 2.1 (appending the PCK into the executable), but this implementation also patches a dedicated section in the ELF/PE executable so that it matches the appended data perfectly.
The usage of integer types is simplified in existing code; namely, using plain `int` for small quantities.
The fix for EditorNode is a bit hacky, but the handling of the buttons
and features there is hacky too (based on enums that might not reflect
the actual state).
Godot core needs MD5/SHA256/AES/Base64 which used to be provided by
separate libraries.
Since we bundle mbedtls in most cases, and we can easily only include
the needed sources if we so desire, let's use it.
To simplify library changes in the future, and better isolate header
dependencies all functions have been wrapped around inside a class in
`core/math/crypto_base.h`.
If the mbedtls module is disabled, we only bundle the needed source
files independently of the `builtin_mbedtls` option.
If the module is enabled, the `builtin_mbedtls` option works as usual.
Also remove some unused headers from StreamPeerMbedTLS which were
causing build issues.
