Have you seen my comments I just posted on IRC?

<snip>
00:45 < mezcalero> elmarco: ok, i thought about this a bit now
00:45 < mezcalero> elmarco: here's my proposal
00:45 < mezcalero> elmarco: introduce pa_ext_stream_restore_info2 and add new entries at the end
00:45 < mezcalero> elmarco: declare that structure as extensible without being considered api/abi breakage
00:46 < mezcalero> then
00:46 < mezcalero> introduce pa_ext_stream_restore_write2()
00:46 < mezcalero> which takes a const pa_ext_stream_restore_info2**
00:46 < mezcalero> instead of pa_ext_stream_restore_info[]
00:46 < mezcalero> i.e. an array to pointers, instead of a simple array
00:46 < mezcalero> then
00:47 < mezcalero> beef up pa_ext_stream_restore_read() accordingly
00:47 < mezcalero> i.e. pa_ext_stream_restore_read2() which hands the new struct to the callback
00:47 < mezcalero> finally, as last step
00:47 < mezcalero> move the negotiation of extensions into connection setup
00:48 < mezcalero> i.e. in the response to AUTH we get a list of supported extensions
00:48 < mezcalero> plus their versions
00:48 < mezcalero> and then keep that around forever
00:49 < mezcalero> then we don't have to to enforce rules like "you have to run test first"
00:49 < mezcalero> elmarco: how does that sound to you?
00:49 < mezcalero> this would mean, two new calls, one new type, two new prototypes
00:49 < mezcalero> it's not that bad i would say
00:50 < mezcalero> the old versions of those calls, types, prototypes we would hide from doxygen
00:50 < mezcalero> elmarco: please ack!
</snip>

I think if we do this we should have all thinks in place to allow
further changes without breaking API/ABI. Including those Colin and I
were discussing.
