X-Git-Url: http://git.ipfire.org/gitweb/?a=commitdiff_plain;h=ac946a80d56672ad783f7239056357b11730e72d;p=thirdparty%2Fopenssl.git

ugment p_ossltest with encoder/decoder/store algs

Create dummy encoder/decoder and store algs in p_ossltest.

They do nothing, except return algorithms on query.  This allows our
unit test 30-test_evp_list_noncache.t to exercise the refcounting of
these objects when the provider requests no caching
