This flag was introduced at the same time as SSL_MODE_ENABLE_PARTIAL_WRITE in OpenSSL 0.9.4 and makes usage with non-blocking sockets much easier. Before this, a Rubyist would need to remember the exact object which failed to write and reuse it later when the socket became writable again. This causes problems when the buffer is given by another layer of the application (e.g. a buffer is given by a Rack middleware or application to a Rack web server). * ext/openssl/ossl_ssl.c (ossl_sslctx_s_alloc): enable SSL_MODE_ACCEPT_MOVING_WRITE_BUFFER by default ~~~ Related to https://bugs.ruby-lang.org/issues/12085 I'm not sure if this can be considered a bugfix which should be backported. I have found write_nonblock usability to be severely hampered by the lack if this flag. ---Files-------------------------------- 0001-openssl-accept-moving-write-buffer-for-write_nonbloc.patch (2.53 KB) -- https://bugs.ruby-lang.org/ Unsubscribe:
