Description
Describe the bug
Fail to write the array content into the file, although print success.
Steps to reproduce
(1)The test case is :
#include <stdio.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 path_rename_00001_gApN2() {
printf("Enter function path_rename_00001_gApN2\n");
if(renameat(AT_FDCWD, "subdir_3/subfile_2", AT_FDCWD, "NEWNAME") == 0) {
printf("File or directory renamed successfully.\n");
} else {
printf("Error renaming file or directory.\n");
}
}
int main() {
path_rename_00001_gApN2();
return 0;
}
(2)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
(3)Running wasm:
(Before run the Wasm file, subdir_3/subfile_2 exists.)
wasmer run --dir=. test.wasm
Expected behavior
print:
Enter function path_rename_00001_gApN2
File or directory renamed successfully.
This is what wasmtime, WAMR and WasmEdge do.
Actual behavior
wasmer print:
Enter function path_rename_00001_gApN2
Error renaming file or directory.
