Support getting global type from `wasm_runtime_get_import_type` and
`wasm_runtime_get_export_type`, and add two APIs:
```C
wasm_valkind_t
wasm_global_type_get_valkind(const wasm_global_type_t global_type);
bool
wasm_global_type_get_mutable(const wasm_global_type_t global_type);
```
If there is no else branch, make a virtual else opcode for easier integrity
check and to copy the correct results to the block return address for
fast-interp mode: change if block from `if ... end` to `if ... else end`.
Reported in issue #3386, #3387, #3388.
In classic interpreter, fast interpreter and fast-jit running modes, set the local
variables' default value to NULL_REF (0xFFFFFFFF) rather than 0 if they are type
of externref or funcref.
The issue was reported in #3390 and #3391.
Fix aot debugger compilation error on windows as reported in #3184.
And update the stack size configuration for product-mini zephyr sample
since the native stack overflow check was enhanced and the zephyr-sdk
was also upgraded.
- Add a few API (https://github.com/bytecodealliance/wasm-micro-runtime/issues/3325)
```c
wasm_runtime_detect_native_stack_overflow_size
wasm_runtime_detect_native_stack_overflow
```
- Adapt the runtime to use them
- Adapt samples/native-stack-overflow to use them
- Add a few missing overflow checks in the interpreters
- Build and run the sample on the CI
Fix the integer overflow issue when checking target branch depth in opcode
br_table, and fix is_32bit_type not check VALUE_TYPE_ANY issue, which may
cause wasm_loader_push_frame_offset push extra unneeded offset.
Add WASI support for esp-idf platform:
1. add Kconfig and cmake scripts
2. add API "openat" when using littlefs
3. add clock/rwlock/file/socket OS adapter
The old value (1KB) doesn't seem sufficient for many cases.
I suspect that the new value is still not sufficient for some cases.
But it's far safer than the old value.
Consider if the classic interpreter loop (2600 bytes) calls
host snprintf. (2000 bytes)
Fixes: https://github.com/bytecodealliance/wasm-micro-runtime/issues/3314
Fix wasm loader integrity checks for opcode ref.func and opcode else:
for opcode ref.func, the function must be an import, exported, or present in a
table elem segment or global initializer to be used as the operand to ref.func,
for opcode else, there must not be an else opcode previously.
Reported in #3336 and #3337.
And fix mini loader PUSH_MEM_OFFSET/POP_MEM_OFFSET macro
definitions due to the introducing of memory64 feature.
This PR fixes a readir for posix. readdir is not working correctly in rust.
The current WAMR's readdir implementation for posix is, if readdir returns 0,
it will exit with an error. But posix readdir returns 0 at the end of the directory.
To handle this correctly, if readdir returns 0, it should only raise an error if
errno has changed. We can reproduce it with the following rust code:
```rust
use std::fs;
fn main() {
let entries = fs::read_dir(".").unwrap();
for entry in entries {
println!("read_dir:{:?}", entry);
}
}
```
Some issues are related with memory fragmentation, which may cause
the linear memory cannot be allocated. In WAMR, the memory managed
by the system is often trivial, but linear memory usually directly allocates
a large block and often remains unchanged for a long time. Their sensitivity
and contribution to fragmentation are different, which is suitable for
different allocation strategies. If we can control the linear memory's allocation,
do not make it from system heap, the overhead of heap management might
be avoided.
Add `mem_alloc_usage_t usage` as the first argument for user defined
malloc/realloc/free functions when `WAMR_BUILD_ALLOC_WITH_USAGE` cmake
variable is set as 1, and make passing `Alloc_For_LinearMemory` to the
argument when allocating the linear memory.
Enhance the GC subtyping checks:
- Fix issues in the type equivalence check
- Enable the recursive type subtyping check
- Add a equivalence type flag in defined types of aot file, if there is an
equivalence type before, just set it true and re-use the previous type
- Normalize the defined types for interpreter and AOT
- Enable spec test case type-equivalence.wast and type-subtyping.wast,
and enable some commented cases
- Enable set WAMR_BUILD_SANITIZER from cmake variable
`posix_fadvise()` returns 0 on success and the errno on error. This
commit fixes the handling of the return value such that it does not
always succeeds.
Fixes#3322.
1. Fix API "futimens" and "utimensat" compiling error in different esp-idf version
2. Update component registry description file
ps. refer to PR #3296 on branch release/1.3x
For use with WAMR_BUILD_LIB_PTHREAD, add os_thread_detach,
os_thread_exit, os_cond_broadcast.

The current frame was freed before tail calling to an import or native function
and the prev_frame was set as exec_env's cur_frame, so after the tail calling,
we should recover context from prev_frame but not current frame.
Found in https://github.com/bytecodealliance/wasm-micro-runtime/issues/3279.
When thread manager is enabled, the aux stack of exec_env may be allocated
by wasm_cluster_allocate_aux_stack or disabled by setting aux_stack_bottom
as UINTPTR_MAX directly. For the latter, no need to free it.
And fix an issue when paring `--gc-heap-size=n` argument for iwasm, and
fix a variable shadowed warning in fast-jit.
