* autogen.sh:

Don't use deprecated autoconf macros. Use AM 1.9. Bug #383527.

* ORBit2: The previous two ChangeLog entries are hiding a lot of
details which I'll hereby try to expand upon.
The rationale for these changes is that any and all occurrences of
g_cond_wait() in ORBit2 has the potential to block forever if it
waits for a connection attempt to complete if said connection
attempt is made towards a remote server which happens to be
physically disconnected or powered off.
This blocking behavior can be demonstrated by invoking an operation
on a remote object that is physically inaccessible such as when
the remote server is powered down or physically disconnected.
Pseudo code:
{
CORBA_ORB orb = get_orb();
char *objref = get_corbaloc_str();
CORBA_Object obj = CORBA_OBJECT_NIL;
CORBA_Environment ev[1];
CORBA_exception_init(ev);
obj = CORBA_ORB_string_to_object(orb, objref, ev);
FOO_INTERFACE_method(obj, <arguments>, ev);
}
The last statement above will block forever in g_cond_wait() while
waiting for the recieve buffer to be ready if the remote server is,
say, powered down. An exception is on the other hand immediately
thrown if the server object is merely gone.
The changes to the code therefore boils down to the implementation
of the ex_CORBA_TIMEOUT system exception being thrown if
g_cond_timed_wait() times out. Most occurrences of g_cond_wait()
has been replaced by g_cond_timed_wait().
The only remaining instance of g_cond_wait() is found in
link_exec_command(). I haven't observed any problems with
link_exec_command() so I've not touched that code.
The affected code is:
1) A new ORB command line option: GIOPTimeoutLimit - timeout limit
in microseconds. Defaults to 30 seconds.
2) giop_recv_buffer_get(). This one is obvious. We do not want to
wait indefinitely for data to be received from a downed host. The
waiting interval is configurable with the new GIOPTimeoutLimit ORB
option.
3) Any code invoking link_wait():
a) link_connection_wait_connected_T()
b) link_connection_try_reconnect()
c) giop_connection_try_reconnect(), calls link_connection_try_reconnect()
d) ORBit_try_connection_T(), calls giop_connection_try_reconnect()
e) ORBit_object_get_connection(), calls ORBit_try_connection_T()
4) The waiting time in link_wait() is set at compile time to
LINK_WAIT_TIMEOUT_USEC which is presently 10 seconds.
5) link_wait() has been modified to return a gboolean. FALSE if the
timeout expired, TRUE otherwise.
6) link_connection_wait_connected_T() and link_connection_try_reconnect()
will both disconnect the connection if link_wait() experienced a timeout.

* configure.in: Added autoconf 2.60+ required datarootdir variable
2006-12-03 Jules Colding <colding@omesc.com>
* include/orbit/GIOP/giop.h: Declare giop_recv_set_timeout().
* src/orb/orb-core/corba-orb.c (CORBA_ORB_init): Set GIOP timeout
limit from the ORB option.
Added new ORB option - GIOPTimeoutLimit.
* src/orb/orb-core/orbit-small.c (ORBit_small_invoke_stub): Throw a
TIMEOUT exception if a reply hasn't been recieved within the GIOP
timeout limit.
* src/orb/GIOP/giop-recv-buffer.c (giop_recv_buffer_get): Replaced
a g_cond_wait() with a g_cond_timed_wait(). The original g_cond_wait()
could potentially block forever if a remote server was physically
offline.
(giop_recv_set_timeout): Function to adjust the GIOP timeout limit.
