commit 66798dfdc069ffc2ce1a9cb84529d2015dd3cd66 Author: Nick Mathewson nickm@torproject.org Date: Thu Jul 17 11:25:56 2014 +0200
Fix compilation with no-compression OpenSSL builds and forks
Found because LibreSSL has OPENSSL_NO_COMP always-on, but this conflicts with the way that _we_ turn off compression. Patch from dhill, who attributes it to "OpenBSD". Fixes bug 12602; bugfix on 0.2.1.1-alpha, which introduced this turn-compression-off code. --- changes/bug12602 | 5 +++++ src/common/tortls.c | 2 ++ 2 files changed, 7 insertions(+)
