New submission from Wang Chun <[EMAIL PROTECTED]>:
Consider the following program tmp.py:
import sys, getopt
print(getopt.getopt(sys.argv[1:], '', ['help']))
The program accept "--help" without a value:
python helloworld.py --help
But if someone invoke the program like:
python helloworld.py --help=
Python should raise an error.
"--help=" is not considered as no_argument in libc's getopt implementation
(tested on Mac OS X
Leopard):
#include <getopt.h>
static struct option longopts[] = {
{ "help", no_argument, NULL, "h" },
};
#include <getopt.h>
static struct option longopts[] = {
{ "help", no_argument, NULL, 'h' },
};
int main(int argc, char **argv)
{
while (getopt_long(argc, argv, "h", longopts, NULL) != -1);
return 0;
}
macbook:~/tmp$ gcc -o tmp tmp.c
macbook:~/tmp$ ./tmp --help=
tmp: option `--help' doesn't allow an argument
