Hello,
While browsing the source I noticed something that seemed wrong, even
though I haven't observed any buggy behavior or have reproduced this bug
myself. In ngx_event.c there is a line:
if (ngx_shmtx_create(&ngx_accept_mutex, (ngx_shmtx_sh_t *) shared,
cycle->lock_file.data)
!= NGX_OK)
{
return NGX_ERROR;
}
ngx_shmtx_create() is passed &ngx_accept_mutex, but this must be a
pointer to a shared memory region otherwise the sem_wait()/sem_post()
calls in ngx_shmtx.c will not function correctly. &ngx_accept_mutex is a
pointer to BSS, ngx_accept_mutex_ptr is a pointer to shared memory. Is
this intentional?
Rian
