mod_rewrite has a race condition with threaded mpms:
static int rewrite_rand_init_done = 0;
static void rewrite_rand_init(void)
{
if (!rewrite_rand_init_done) {
srand((unsigned)(getpid()));
rewrite_rand_init_done = 1;
}
return;
}
and mod_ssl calls srand(time(NULL)) on *every* request if
'SSLRandomSeed connect builtin' is configured.
i was thinking there should be an ap_srand() that can be called by modules
in the child_init hook. something like:
static int ap_srand_init = 0;
AP_DECLARE(void) ap_srand(void)
{
if (!ap_srand_init) {
srand(...);
ap_srand_init = 1;
}
}
this will help ensure srand() is only called once per-process and avoid
the race condition. thoughts?
only snag is it looks like all MPMs except for beos call
ap_run_child_init(), any reason the beos mpm shouldn't be calling it?
