Function removed. + (packet_new_size): New function. + + * pq.c (packet_read): Re-arrange to be slightly less confusing. + Reverse start-past-buf-beginning test that may have leaked memory. + + * pipe.c (pipe_send): For non-blocking writes, avoid writing more + than the user requested. + +Fri Jan 12 12:15:06 1996 Miles Bader <miles@gnu.ai.mit.edu> + + * pq.c (pq_queue): Initialize the

when the pipe + breaks. + +Fri Sep 1 10:42:03 1995 Miles Bader <miles@churchy.gnu.ai.mit.edu> + + * pipe.c (_pipe_no_readers): Wake up write selects too when the + pipe breaks. + +Thu Aug 31 14:39:21 1995 Miles Bader <miles@churchy.gnu.ai.mit.edu> + + * pipe.c (pipe_send): Make writes blockable. + (pipe_recv): Wakeup blocked writers. + (pipe_kick): Function deleted. + (pipe_create): Make

(pipe_break): Function decl deleted. + +Tue Aug 1 12:37:27 1995 Miles Bader <miles@churchy.gnu.ai.mit.edu> + + * pipe.c (pipe_recv): Get rid of code to deal with getting the + source address from the

a control packet should only + have a source address if there is no corresponding data packet. + (pipe_send): Change the test to determine whether we should write + a control packet, so that we only do so if we need to. Also, + don't record the source address in control packets, as it's + recorded in the following data packet anyway, and this prevents it + from being dealloc'd twice. + +Fri Jul 28 23:03:27 1995 Miles Bader <miles@churchy.gnu.ai.mit.edu> + + * pipe.h (stream_pipe_class, dgram_pipe_class, seqpack_pipe_class): + Make these declarations extern so they don't fuck up initialization. + (seqpacket_pipe_class): Renamed to `seqpack_pipe_class'. |
