The idea of this test tool is to check the sanity of the LD_PRELOAD + * mechanism in libc for the system on which booster needs to run. + * + * 2. Basically, this test tool calls various system calls for which there is + * support in the booster library. Combined with the logging output from this + * tool and the preload-test-lib, one can determine whether the + * pre-loading mechanism is working working in order for booster to initialize. + * + * 3. This tool does not test GlusterFS functionality running under booster + * although the path specified to the tool can be a GlusterFS mountpoint but + * that is not very useful. + * + * 4. This tool is incomplete without the preload-test-lib and the + * accompanyung shell script that needs to be run for running the test. + */ +#define _XOPEN_SOURCE 500 + +#include <dlfcn.h> +#include <sys/types.h> +#include <stdio.h> +#include <stdarg.h> +#include <stdlib.h> +#include <inttypes.h> +#include <string.h> +#include <assert.h> +#include <errno.h> +#include <dirent.h> +#include <sys/statfs.h> +#include <sys/statvfs.h> +#include <sys/stat.h> +#include <fcntl.h> +#include <unistd.h> +#include <sys/uio.h> +#include <utime.h> +#include <sys/time.h> +#include <attr/xattr.h> +#include <sys/sendfile.h> + + +#define PRELOAD_ERRNO_VERF 6449 +inline void +check_err(int ret, char *call, int tabs) +{ + while (tabs > 0) { + fprintf (stdout, "\t");
