330. [func] New function isc_log_wouldlog().
(note: #330 is out of place in CHANGES, because it's new in rc4, but if
it was in the place that 330 is supposed to go, no one would see it. So,
leave it at the top)
state. Set DNS_DISPATCHATTR_CONNECTED when calling
dns_dispatch_createtcp() for connected TCP sockets
or call dns_dispatch_starttcp() when the socket is
connected.
dns_dispatch_create() no longer exists. dns_dispatch_createtcp()
and dns_dispatch_getudp() are the replacements. _createtcp() takes
a bound, connected TCP socket, while _getudp() will search for
a sharable UDP socket, and if found, attach to it and return a
pointer to it. If one is not found, it will create a udp socket,
bind it to a supplied local address, and create a new dispatcher
around it.
dns_dispatch_remove{request,response}() no longer take the dispatch
as an argument.
query-source can now be set per view.
The dispatch manager holds onto three memory pools, one for
allocating dispatchers from, one for events, and one for
requests/replies. The free list on these pools is hard-coded,
but set to 1024. This keeps us from having to dig into the
isc_mem_t the pools draw from as often.
dns_resolver_create() and dns_view_createresolver() require that
valid dispatchers be passed in; dispatchers are no longer created
for the caller.
Cleanup of redundant/useless header file inclusion.
ISC style lint, primarily for function declarations and standalone
comments -- ie, those that appear on a line without any code, which
should be written as follows:
/*
* This is a comment.
*/
Added:
isc_buffer_base(b) (pointer)
isc_buffer_current(b) (pointer)
isc_buffer_active(b) (pointer)
isc_buffer_used(b) (pointer)
isc_buffer_length(b) (int)
isc_buffer_usedlength(b) (int)
isc_buffer_consumedlength(b) (int)
isc_buffer_remaininglength(b) (int)
isc_buffer_activelength(b) (int)
isc_buffer_availablelength(b) (int)
Removed:
ISC_BUFFER_USEDCOUNT(b)
ISC_BUFFER_AVAILABLECOUNT(b)
isc_buffer_type(b)
Changed names:
isc_buffer_used(b, r) ->
isc_buffer_usedregion(b, r)
isc_buffer_available(b, r) ->
isc_buffer_available_region(b, r)
isc_buffer_consumed(b, r) ->
isc_buffer_consumedregion(b, r)
isc_buffer_active(b, r) ->
isc_buffer_activeregion(b, r)
isc_buffer_remaining(b, r) ->
isc_buffer_remainingregion(b, r)
Buffer types were removed, so the ISC_BUFFERTYPE_*
macros are no more, and the type argument to
isc_buffer_init and isc_buffer_allocate were removed.
isc_buffer_putstr is now void (instead of isc_result_t)
and requires that the caller ensure that there
is enough available buffer space for the string.
