liang.he	0b97d0cb14	Merge dev/zephyr_file_socket into main (#4347) ... zephyr: Enable WASI support for file system and sockets on zephyr (#3633) This work also implements the WASI support on Zephyr. * Added os_is_* methods for stdin/stdout/stderr. Fixed issues in os_renameat * Zephyr platform fixes for WASI sockets Addressed numerous of build warnings on Zephyr * Updated `os_writev` to use `fwrite` for STDOUT/STDERR * Temporarily reverted change to `writev` to work around an issue. * Fixes: fstat, fstatat, and unlink * Add initial support for directories in os_openat. Partial implementation — just avoids a hard fault. * Directory support WIP. readdir works but I think we have a memory leak somewhere * Fix: always use standard stream fds. Fix unlinkat and renameat. fd 0, 1, and 2 will always be supplied for standard streams. Unlinkat and renameat work exclusively based on supplied paths. * Fix: use macro for free() * Added a temporary workaround for issue identified in PR#4377 * Fixed reference to file descriptor and cleaned up dead/commented code. Note that some comments haven't been addressed and will be fixed in the further patches.

Marcin Kolny	b882017674	Fix compiler warnings (#3784) ... The definition of os_get_invalid_handle in platform_internal.h did not match the declaration in platform_api_extension.h.	2024-09-11 08:59:16 +08:00
Gavin Hayes	bf9fb2e680	cosmopolitan: Update compiler and update platform_internal.h (#3079) ... 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.	2024-01-24 16:04:48 +08:00
Marcin Kolny	ffa131b5ac	Allow using mmap for shared memory if hw bound check is disabled (#3029) ... 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.	2024-01-16 22:15:55 +08:00
zoraaver	fa5e9d72b0	Abstract POSIX filesystem functions (#2585) ... To allow non-POSIX platforms such as Windows to support WASI libc filesystem functionality, create a set of wrapper functions which provide a platform-agnostic interface to interact with the host filesystem. For now, the Windows implementation is stubbed but this will be implemented properly in a future PR. There are no functional changes in this change, just a reorganization of code to move any direct POSIX references out of posix.c in the libc implementation into posix_file.c under the shared POSIX sources. See https://github.com/bytecodealliance/wasm-micro-runtime/issues/2495 for a more detailed overview of the plan to port the WASI libc filesystem to Windows.	2023-10-19 19:19:39 +08:00
Gavin Hayes	d8ee771e28	Add Cosmopolitan Libc Platform (#2598) ... This PR adds the Cosmopolitan Libc platform enabling compatibility with multiple x86_64 operating systems with the same binary. The platform is similar to the Linux platform, but for now only x86_64 with interpreter modes are supported. The only major change to the core is `posix.c/convert_errno()` was rewritten to use a switch statement. With Cosmopolitan errno values depend on the currently running operating system, and so they are non-constant and cannot be used in array designators. However, the `cosmocc` compiler allows non-constant case labels in switch statements, enabling the new version. And updated wamr-test-suites script to add `-j <platform>` option. The spec tests can be ran via `CC=cosmocc ./test_wamr.sh -j cosmopolitan -t classic-interp` or `CC=cosmocc ./test_wamr.sh -j cosmopolitan -t fast-interp`.	2023-10-04 21:55:37 +08:00
