It's 2018, but passing STL objects across the API boundary turns out to still be more bother than it's worth. Since we're dropping UniquePtr in the API anyway, go the whole way and make it a plain-C API. Change-Id: Ic0202012e5d81afe62d71b3fb57e6a27a8f63c65 Update-note: this will need corresponding changes to the internal use of SSL_CTX_add_cert_compression_alg.

BoringSSL SSL Tests
This directory contains BoringSSL's protocol-level test suite.
Testing a TLS implementation can be difficult. We need to produce invalid but sufficiently correct handshakes to get our implementation close to its edge cases. TLS's cryptographic steps mean we cannot use a transcript and effectively need a TLS implementation on the other end. But we do not wish to litter BoringSSL with options for bugs to test against.
Instead, we use a fork of the Go crypto/tls package, heavily patched with
configurable bugs. This code, along with a test suite and harness written in Go,
lives in the runner directory. The harness runs BoringSSL via a C/C++ shim
binary which lives in this directory. All communication with the shim binary
occurs with command-line flags, sockets, and standard I/O.
This strategy also ensures we always test against a second implementation. All features should be implemented twice, once in C for BoringSSL and once in Go for testing. If possible, the Go code should be suitable for potentially upstreaming. However, sometimes test code has different needs. For example, our test DTLS code enforces strict ordering on sequence numbers and has controlled packet drop simulation.
To run the tests manually, run go test from the runner directory. It takes
command-line flags found at the top of runner/runner.go. The -help option
also works after using go test -c to make a runner.test binary first.
If adding a new test, these files may be a good starting point:
runner/runner.go: the test harness and all the individual tests.runner/common.go: contains theConfigandProtocolBugsstruct which control the Go TLS implementation's behavior.test_config.h,test_config.cc: the command-line flags which control the shim's behavior.bssl_shim.cc: the shim binary itself.
For porting the test suite to a different implementation see PORTING.md.
