When using proxy_to_pthread we add BIGINT support (to support exchanging
64 bits integers between wasm and JS).
Bigint though, is part of ECMAScript 2020, and the closure compiler was
using ECMAScript 6 instead.
This commit update the CC configuration to use ECMAScript 2020 instead.
After changing the default visibility to hidden to avoid generating
thousands of import/export symbols (browsers have a hard limit of 10k),
explicitly setting visibility for "boundary functions" (i.e. wasm
callbacks called by JS via pointer) is required to ensure the function
can be retrieved via pointer from the function table.
Remove the base error message in `OS`, we no longer really error out this
way for not implemented methods. Instead, each platform should override them
to provide the context they want.
Fixes#82439.
This fixes multiple issues/inconsistencies around `get_compiler_version()`:
* With no shell allocated, launching the compiler could fail even
with proper paths being set.
* The return value was described as "an array of version numbers as ints",
but the function actually returned a `Dictionary` (or `None`).
* Not all calls were properly handling a `None` return value in case of errors.
On Windows this broke compiling for me since #81869 with default settings.
* Some calls defined inconsistent defaults/fallbacks (`0` or `-1`).
This means no CPU occlusion culling (and not compiling Embree), unless
you compile custom export templates with `module_raycast_enabled=yes`.
This reduces the memory footprint significantly, and binary size.
Fixes#70621.

It wrongly returned 20 on array buffers, which used to be the enumerator
value of Godot 3.x's type PoolByteArray, and now is the value of type Color,
while it should return 29 which is the enumerator value for PackedByteArray.
Upon investigating the extremely slow MSVC build times in #80513, I noticed
that while Godot policy is to never use exceptions, we weren't enforcing it
with compiler flags, and thus still included exception handling code and
stack unwinding.
This is wasteful on multiple aspects:
- Binary size: Around 20% binary size reduction with exceptions disabled
for both MSVC and GCC binaries.
- Compile time:
* More than 50% build time reduction with MSVC.
* 10% to 25% build time reduction with GCC + LTO.
- Performance: Possibly, needs to be benchmarked.
Since users may want to re-enable exceptions in their own thirdparty code
or the libraries they compile with Godot, this behavior can be toggled with
the `disable_exceptions` SCons option, which defaults to true.
Body length cannot be reliably retrieved from the web.
Reading the "content-length" value will return a meaningless value when
the response is compressed, as reading will return uncompressed chunks
in any case, resulting in a mismatch between the detected body size and
the actual size returned by repeatedly calling read_response_body_chunk.
Additionally, while "content-length" is considered a safe CORS header,
"content-encoding" is not, so using the "content-encoding" to decide if
"content-length" is meaningful is not an option either.
We simply must accept the fact that browsers are awful when it comes to
networking APIs.
This hugely reduces the number of exports, making it acceptable for
browsers.
Note that dlink + threads is still not working due to upstream issues
with the pthread emulation library.
Should hopefully be solved once emscripten move to native WASM threads.
We don't use that info for anything, and it generates unnecessary diffs
every time we bump the minor version (and CI failures if we forget to
sync some files from opt-in modules (mono, text_server_fb).
