Although I don't know what exactly the esp32s3 rom version of memset is,
it seems that the current code crashes only with a small "len". I guess
it changes the logic depending on the size.
Anyway, it's safer to use dbus here.
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
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);
}
}
```
`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.

Adding a new cmake flag (cache variable) `WAMR_BUILD_MEMORY64` to enable
the memory64 feature, it can only be enabled on the 64-bit platform/target and
can only use software boundary check. And when it is enabled, it can support both
i32 and i64 linear memory types. The main modifications are:
- wasm loader & mini-loader: loading and bytecode validating process
- wasm runtime: memory instantiating process
- classic-interpreter: wasm code executing process
- Support memory64 memory in related runtime APIs
- Modify main function type check when it's memory64 wasm file
- Modify `wasm_runtime_invoke_native` and `wasm_runtime_invoke_native_raw` to
handle registered native function pointer argument when memory64 is enabled
- memory64 classic-interpreter spec test in `test_wamr.sh` and in CI
Currently, it supports memory64 memory wasm file that uses core spec
(including bulk memory proposal) opcodes and threads opcodes.

This PR fixes the random failing test case `nofollow_errors` mentioned in
https://github.com/bytecodealliance/wasm-micro-runtime/issues/3222
```C
// dirfd: This is the file descriptor of the directory relative to which the pathname is interpreted.
int openat(int dirfd, const char *pathname, int flags, ...);
```
The value should be a directory handle instead of a file handle (which is always -1 in this context)
returned from `openat`.
Now that the filesystem implementation is now complete, the previous
test filters on Windows can be removed. Some of the tests only pass when
certain environment variables have been set on Windows so an extra step
has been added in the wasi test runner script to modify the test config
files before the tests begin.
Use math functions only with `CONFIG_MINIMAL_LIBC=y`.
`CONFIG_PICOLIBC=y` or `CONFIG_NEWLIB_LIBC=y` provides math functions
that are used by wasm, and compilation fails when they are selected.

When running AOT code in Zephyr on STM32H743VIT6 without
CONFIG_CACHE_MANAGEMENT=y, a hard fault occurs, which leads to
SCB_CleanDCache().
It’s better to use the functions built into Zephyr.
As an original design rule, the code in `core/shared/platform` should not
rely on the code in `core/share/utils`. In the current implementation,
platform layer calls function `bh_memory_remap_slow` in utils layer.
This PR adds inline function `os_mremap_slow` in platform_api_vmcore.h,
and lets os_remap call it if mremap fails. And remove bh_memutils.h/c as
as they are unused.
And resolve the compilation warning in wamrc:
```bash
core/shared/platform/common/posix/posix_memmap.c:255:16:
warning: implicit declaration of function ‘bh_memory_remap_slow’
255 | return bh_memory_remap_slow(old_addr, old_size, new_size);
```
With this approach we can omit using memset() for the newly allocated memory
therefore the physical pages are not being used unless touched by the program.
This also simplifies the implementation.
After #2995, AOT may stop working properly on arm MacOS:
```bash
wasm-micro-runtime/core/iwasm/common/wasm_runtime_common.c,
line 1270, WASM module load failed
AOT module load failed: mmap memory failed
```
That's because, without `#include <TargetConditionals.h>`, `TARGET_OS_OSX` is undefined,
since it's definition is in that header file.
This fixes the cosmopolitan platform.
- Switch `build_cosmocc.sh` and platform documentation to
explicitly use the x86_64 cosmocc compiler as multi-arch
cosmocc won't work here. Older version `cosmocc` just did
a x86_64 build.
- Add missing items from `platform_internal.h` to fix build.
When WAMR is embedded to other application, the lifecycle of the socket
might conflict with other usecases. E.g. if WAMR is deinitialized before any
other use of sockets, the application goes into the invalid state. The new
flag allows host application to take control over the socket initialization.
Enhance the statistic of wasm function execution time, or the performance
profiling feature:
- Add os_time_thread_cputime_us() to get the cputime of a thread,
and use it to calculate the execution time of a wasm function
- Support the statistic of the children execution time of a function,
and dump it in wasm_runtime_dump_perf_profiling
- Expose two APIs:
wasm_runtime_sum_wasm_exec_time
wasm_runtime_get_wasm_func_exec_time
And rename os_time_get_boot_microsecond to os_time_get_boot_us.
For shared memory, the max memory size must be defined in advanced. Re-allocation
for growing memory can't be used as it might change the base address, therefore when
OS_ENABLE_HW_BOUND_CHECK is enabled the memory is mmaped, and if the flag is
disabled, the memory is allocated. This change introduces a flag that allows users to use
mmap for reserving memory address space even if the OS_ENABLE_HW_BOUND_CHECK
is disabled.
Compilation error was reported when `cmake -DWAMR_BUILD_LIBC_WASI=0`
on linux-sgx platform:
```
core/shared/platform/linux-sgx/sgx_socket.c:8:10:
fatal error: libc_errno.h: No such file or directory
8 | #include "libc_errno.h"
| ^~~~~~~~~~~~~~
```
After fixing, both `cmake -DWAMR_BUILD_LIBC_WASI=1` and
`WAMR_BUILD_LIBC_WASI=0` work good.
`pthread_jit_write_protect_np` is only available on macOS, and
`sys_icache_invalidate` is available on both iOS and macOS and
has no restrictions on ARM architecture.
On macOS, by default, the first 4GB is occupied by the pagezero.
While it can be controlled with link time options, as we are
an library, we usually don't have a control on how to link an
executable.
before the change, only support wasm app exit like:
```c
void *thread_routine(void *arg)
{
printf("Enter thread\n");
return NULL;
}
```
if call pthread_exit, it will crash:
```c
void *thread_routine(void *arg)
{
printf("Enter thread\n");
pthread_exit(NULL);
return NULL;
}
```
This commit lets both upstairs work correctly, test pass on stm32f103 mcu.
Add an extra argument `os_file_handle file` for `os_mmap` to support
mapping file from a file fd, and remove `os_get_invalid_handle` from
`posix_file.c` and `win_file.c`, instead, add it in the `platform_internal.h`
files to remove the dependency on libc-wasi.
