From 59b843517df8d35b339eaee95ba4e533b190f9d6 Mon Sep 17 00:00:00 2001 From: Valerii Hiora Date: Thu, 9 Oct 2014 12:33:29 +0300 Subject: BN_is_zero as a Rust function MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Although wrapping was relatively easy it basically meant that we depend on C compilation which becomes nightmare as soon as multiple platforms are used. I’ve got a huge pain once iOS was involved with 3 device archs and 2 simulator arches to support, not mentioning different set of include and lib flags. So there are 2 different approaches: - continue this way, maintaining all compilation issues like like managing correct flags, providing correct paths and so on. This way our Makefile will grow extremely fast and will actually take more efforts to maintain. - doing it pure Rust way. In this case we provide all the macros expansions inside our wrappers and there should be no other way to access raw data other than through those wrappers. It might be fragile if OpenSSL internal data structures will ever change, but I think (or hope) it is pretty stable and wouldn’t change anytime soon. This PR eliminates `BN_is_zero` at all from public API. It’s functionality is implemented in `BigNum.is_zero` and should be enough. Additional notes: 1. I’ve moved BIGNUM into `bn` so it could access fields directly and keep it as an opaque structure for everyone else 2. I’ve kept empty Makefile as I hope to land `feature-matrix` branch soon and I don’t like merging deleted/added file conflicts. --- src/ssl/tests.rs | 13 ------------- 1 file changed, 13 deletions(-) (limited to 'src/ssl') diff --git a/src/ssl/tests.rs b/src/ssl/tests.rs index f98352be..a68d4967 100644 --- a/src/ssl/tests.rs +++ b/src/ssl/tests.rs @@ -237,16 +237,3 @@ fn test_cert_gen() { // FIXME: check data in result to be correct, needs implementation // of X509 getters } - -#[test] -fn test_bn_is_zero() { - use ffi; - use std::ptr; - - unsafe { - let bn = ffi::BN_new(); - assert!(bn != ptr::null_mut()); - // Just make sure it is linked and resolved correctly - ffi::BN_is_zero(bn); - } -} -- cgit v1.2.3
