-- Check consistency of error translation for each of the backends - with the design document. - -- check stream creation arguments such as element-type and external-format - for availability in the different lisps. - - Extend ABCL socket support with the 4 java errors in java.net.* so that they can map to our usocket errors instead of mapping all errors to unknown-error.
-- Investigate which backends would support streams with other - elements than :element-type 'character, especially since - cl-irc chokes on characters which are non-UTF8 conforming... - Probably other clients do too (try that with a binary HTTP stream!) - -- change CMUCL implementation to catch name resolution errors: - Don't send host names into connect-to-inet-socket, but use - gethostbyname, binding the return value and the error code. - Raise an error if gethostbyname returns one. - - Add INET6 support. + +For more TODO items, see http://trac.common-lisp.net/usocket/report.
