Hi,

I just noticed that ngx_reopen_files() treats the file name as a null
terminated string but there is no guarantee that a ngx_str_t will be null
terminated.

I noticed in ngx_string.h that the ngx_string() macro sets the length to be
exclusive of the null termination character, however the null termination
would still be present at s.data[s.len]

However ngx_pstrdup() in ngx_string.c only copies the size of s.len - so if
there is a null character at s.data[s.len] it will not be copied.

Could you please help clarify the correct way to handle the strings?

-Andrew
