This was not to be a debate on what is the best MTA. I respectfully
disagree on all counts. Postfix will not do half of the things we use
qmail for. But no matter, not the point. I've used and managed both. The
question is about execv.
The execv (added more code) returns an error 2, or, file not found on
Leopard.
That's odd. I'd probably replace it with "/bin/pwd" and see what it says. :)
It says the correct directory. Which is to be expected.
Could it be a bug in execv on Leoprd when when not using a absolute
filename?
No, because as a simple test program shows, that works:
static char *ev[] = { 0, 0 };
int
main(void) {
ev[0] = "bin/ls";
chdir("/");
execv(*ev, ev);
return 23;
}
This will run ls and return 0, suggesting that execv can handle non-absolute
path names.
Conclusion: Something else has gone wrong.
I disagree, your test is not the same.
Recall, qmail is the second most deployed MTA ,and, the code works on
all platforms, including Tiger as is. The code appears correct. The
extra code shows it to be in the right directory, as it does when
rec-compiled on our Tiger servers. So, my conclusion is different.
Anyone else? Can we stick to the topic?
Steve
