See gnulib/lib/error.c:118 What actually happens in gnulib's error.c is: #ifdef _LIBC /* In the GNU C library, there is a predefined variable for this. */ # define program_name program_invocation_name #endif which on glibc causes all uses of `program_name' in the error.c source to refer to refer to a string that glibc defines called `program_invocation_name': extern char *program_invocation_name; /* defined in glibc, same as argv[0]*/ On non-glibc, error.c says: /* The calling...

...ibs/lt-guestfish: write error: No space left on device Obviously, including the absolute program name in the diagnostic is a bug. It should be "guestfish", and there's already code to perform that sanitization in the patch below. It fixes everything except the glibc global variable, program_invocation_name, used by error, called by atexit+close_stdout. I'll fix that via gnulib's progname module later today or tomorrow. Note that all other diagnostics (e.g., below) do use the sanitized name. The second patch is to make guestfish write --help output to stdout, not stderr, per convention. Al...

Hi, as discussed in [1], this series adds a new getprogname module. All it does is providing a getprogname function, much like what is found on e.g. *BSD systems, and using it in gnulib instead of progname. Also, using it explicitly by modules avoids gnulib users the need of either use the progname module (GPL), or to provide program_name (and call set_program_name manually, which is not always
