While wasi proc exit is not a real trap, what the runtime does on it is mostly same as
real traps. That is, kill the siblings threads and represent the exit/trap as the result of
the "process" to the user api. There seems no reason to distinguish it from real traps
here.
Note that:
- The target thread either doesn't care the specific exception type or ignore wasi
proc exit by themselves. (clear_wasi_proc_exit_exception)
- clear_wasi_proc_exit_exception only clears local exception.
Add simple infrastructure to add more unit tests in the future. At the moment tests
are only executed on Linux, but can be extended to other platforms if needed.
Use https://github.com/google/googletest/ as a framework.
As a part of stress-testing we want to ensure that mutex implementation is working
correctly and protecting shared resource to be allocated from other threads when
mutex is locked.
This test covers the most common situations that happen when some program uses
mutexes like locks from various threads, locks from the same thread etc.
- Update lldb patch due to swig was upgraded to 4.1 in macos
- Export LD_LIBRARY_PATH for searching libpython3.10.so when validating wamr-lldb
in Ubuntu-20.04
- Rename lldb-wasm.patch to lldb_wasm.path
When AOT out of bound linear memory access or stack overflow occurs, the call stack of
AOT functions cannot be unwound currently, so from the exception handler, runtime
cannot jump back into the place that calls the AOT function.
We temporarily skip the current instruction and let AOT code continue to run and return
to caller as soon as possible. And use the zydis library the decode the current instruction
to get its size.
And remove using RtlAddFunctionTable to register the AOT functions since it doesn't work
currently.
AOT relocation to aot_func_internal#n is generated by wamrc --bounds-checks=1.
Resolve the issue by applying the relocation in the compilation stage by wamrc and
don't generate these relocations in the AOT file.
Fixes#2471.
We need to apply some bug fixes that were merged to wasi-libc because wasi-sdk-20
is about half a year old.
It is a temporary solution and the code will be removed when wasi-sdk 21 is released.
- Enable debugging a WASM loaded and executed from Python.
- Expose API to enable access to list of host directories. Similar to --dir in iwasm.
- Add another python language binding sample: native-symbol.
- Fix windows wamrc link error: aot_generate_tempfile_name undefined.
- Clear windows compile warnings.
- And rename folder `samples/bh_atomic` and `samples/mem_allocator` to
`samples/bh-atomic` and `samples/mem-allocator`.
## Context
Some native libraries may want to explicitly delete an externref object without
waiting for the module instance to be deleted.
In addition, it may want to add a cleanup function.
## Proposed Changes
Implement:
* `wasm_externref_objdel` to explicitly delete an externeref'd object.
* `wasm_externref_set_cleanup` to set a cleanup function that is called when
the externref'd object is deleted.
Reduce iwasm static and shared library size when CMAKE_STRIP is set and the
build type is "Release". It remains as it is when build type was selected Debug.
In macro bh_memcpy_s, bh_memcy_wa and bh_memmove_s, no need to do extra check
for length is zero or not because it was already done inside of the functions called.
- Inherit shared memory from the parent instance, instead of
trying to look it up by the underlying module. The old method
works correctly only when every cluster uses different module.
- Use reference count in WASMMemoryInstance/AOTMemoryInstance
to mark whether the memory is shared or not
- Retire WASMSharedMemNode
- For atomic opcode implementations in the interpreters, use
a global lock for now
- Update the internal API users
(wasi-threads, lib-pthread, wasm_runtime_spawn_thread)
