Userzxcvbvnm opened issue #8864:
Test Case
The c test case is:
#include <stdio.h> #include <stdlib.h> #include <fcntl.h> #include <unistd.h> int get_fd(const char *filename, int flags) { int fd = open(filename, flags); if (fd == -1) { printf("Get file descriptor of file %s failed!\n", filename); return -1; } else { printf("Get file descriptor of file %s succeed!\n", filename); return fd; } } void closebyfd(int fd) { if (close(fd) == -1) { printf("Close the file %d by descriptor failed!\n", fd); } } void fd_fdstat_set_flags_00030_ZJtyU(int fd) { printf("Enter function fd_fdstat_set_flags_00030_ZJtyU\n"); int flags = fcntl(fd, F_GETFL); flags = flags | O_TRUNC; if (fcntl(fd, F_SETFL, flags) == -1) { printf("Setting flags failed!\n"); } else { printf("Setting flags succeed!\n"); } } void print_flags(int fd){ int flags1 = fcntl(fd, F_GETFL); int access_mode1 = flags1 & O_ACCMODE; if (access_mode1 == O_RDONLY) { printf("Access mode: Read Only\n"); } if (access_mode1 == O_WRONLY) { printf("Access mode: Write Only\n"); } if (access_mode1 == O_RDWR) { printf("Access mode: Read/Write\n"); } if (flags1 & O_TRUNC) { printf("Access mode: O_TRUNC\n"); } if (flags1 & O_APPEND) { printf("Access mode: O_APPEND\n"); } if (flags1 & O_CREAT) { printf("Access mode: O_CREAT\n"); } if (flags1 & O_EXCL) { printf("Access mode: O_EXCL\n"); } if (flags1 & O_NONBLOCK) { printf("Access mode: Non-blocking\n"); } if (flags1 & O_SYNC) { printf("Access mode: Synchronous Write\n"); } if (flags1 & O_DSYNC) { printf("Access mode: Data Synchronization Write\n"); } } int main() { int fd = get_fd("subdir_3/subdir_2/subfile_2", O_WRONLY | O_APPEND); if (fd == -1) { return 1; } print_flags(fd); fd_fdstat_set_flags_00030_ZJtyU(fd); printf("After setting flags\n"); print_flags(fd); closebyfd(fd); return 0; }
Steps to Reproduce
(1)compile to wasm:
./wasi-sdk-21.0/bin/clang --target=wasm32-unkown-wasi --sysroot=./wasi-sdk-21.0/share/wasi-sysroot test.c -o test.wasm
(2)Running wasm:
(Before run the Wasm file, file subdir_3/subdir_2/subfile_2 exists.)
wasmtime run --dir=. test.wasm
Expected Results
Print:
Get file descriptor of file subdir_3/subdir_2/subfile_2 succeed! Access mode: Read/Write Access mode: O_APPEND Enter function fd_fdstat_set_flags_00030_ZJtyU Setting flags succeed! After setting flags Access mode: Read/Write Access mode: O_APPEND
Actual Results
wasmtime prints:
Get file descriptor of file subdir_3/subdir_2/subfile_2 succeed! Access mode: Read/Write Access mode: O_APPEND Enter function fd_fdstat_set_flags_00030_ZJtyU Setting flags succeed! After setting flags Access mode: Read/Write Access mode: O_TRUNC Access mode: O_APPEND
Setting flags succeed, but do not print "Access mode: O_TRUNC".
