-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi,
Just wanted to confirm that the following procedure to change an existing interface: - Remove the symbol in question from all previous FBSD_1.* namespaces with their corresponding Symbol.map files; - Add the new symbol into latest FBSD_1.* namespace, say, FBSD_1.1 for now, into corresponding Symbol.map files; - Create a new file containing the compatibility shims with prefix __ and suffix of something indicating its obsoleteness, e.g. _44bsd. For instance, for function foo(), the shim function would be called __foo_44bsd(); - At the tail of the shim file, add glues for the old symbols like this: __sym_compat(foo, __foo_44bsd, FBSD_1.0); - Double check to make sure that new .so would work with old binaries. Is that correct?
