> Man of getpwuid_r "return a pointer to a passwd structure, or NULL if the
> matching entry is not found or an error occurs",
> "The getpwnam_r() and getpwuid_r() functions return zero on success.", it
> means entry may not be found when getpwuid_r success.
> In log_env of zookeeper.c in c sdk:
> {{if (!getpwuid_r(uid, &pw, buf, sizeof(buf), &pwp)) {}}
> {{LOG_INFO(("Client environment:user.home=%s", pw.pw_dir));}}
> {{}}}
> pwp is not checked to ensure entry is found, pw.pw_dir is not initialized in
> this case, core happens in LOG_INFO.
