+Tue Jul 16 11:33:34 1996  Michael I. Bushnell, p/BSG  <mib@gnu.ai.mit.edu>
+
+	* pipe.h (EWOULDBLOCK): Define to work around new libc bug.
+
+Mon Jul  1 17:29:07 1996  Miles Bader  <miles@gnu.ai.mit.edu>
+
+	* pq.c (pq_queue): Initialize PACKET->buf_vm_alloced.
+
+Tue Jan 23 12:44:40 1996  Miles Bader  <miles@gnu.ai.mit.edu>
+
+	* pq.h (packet_ensure, packet_ensure_efficiently): Use packet_fit().
+	(packet_fit): New function.
+	* pq.c (packet_read): If there's lots of empty space at the
+	beginning of a vm_alloced buffer, deallocate it.
+
+Mon Jan 22 17:12:39 1996  Miles Bader  <miles@gnu.ai.mit.edu>
+
+	* pq.c (packet_realloc): Reflect in the new values of BUF_START &
+	BUF_END that we've removed any empty space at the beginning of BUF.
+
+Sat Jan 13 13:56:13 1996  Miles Bader  <miles@gnu.ai.mit.edu>
+
+	* pq.h 	(packet_ensure, packet_ensure_efficiently): Use
+	packet_new_size() instead of packet_size_adjust().
+	(packet_size_adjust): Declaration removed.
+	(packet_new_size): New declaration.
+	* pq.c (packet_size_adjust): 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 ports_alloced field.
+  	(packet_read): When a page-aligned read consumes the whole buffer,
+ 	but there's a non-page-multiple amount available, don't let
+ 	buf_len become negative.
+
+Mon Oct  9 14:57:48 1995  Roland McGrath  <roland@churchy.gnu.ai.mit.edu>
+
+        * Makefile: Specify shared library dependencies.
+
+Thu Sep  7 09:08:30 1995  Miles Bader  <miles@churchy.gnu.ai.mit.edu>
+
+	* pq.c (packet_read): Don't leave PACKET in a fucked up state when
+ 	it's vm_allocate'd but doesn't a page-multiple amount of data and
+ 	we're reading everything.
+
+	* pipe.c (_pipe_no_readers): REALLY wake up writers 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 connection-oriented pipes start out broken.
+	(_pipe_first_reader): New function.
+	(_pipe_first_writer): Don't check whether PIPE is connection-
+ 	oriented before clearing PIPE_BROKEN, as otherwise it will never
+ 	be set.
+	(pipe_pair_select): New function.
+	(pipe_multiple_lock): New variable.
+	* pipe.h (pipe_wait): Renamed to `pipe_wait_readable'.
+	(pipe_select): Renamed to `pipe_select_readable'.
+	(pipe_writable, pipe_wait_writable, pipe_select_writable): New funcs.
+	(pipe_acquire_reader): Call _pipe_first_reader if necessary.
+	(_pipe_first_reader): New declaration.
+	(struct pipe): New fields: `write_limit', `write_atomic',
+	`pending_writes', `pending_write_selects'.
+	(struct pipe): `pending_selects' changed to `pending_read_selects'.
+	(pipe_pair_select): New declaration.
+
+Tue Aug 29 14:37:49 1995  Miles Bader  <miles@geech.gnu.ai.mit.edu>
+
+	* pipe.c (pipe_send): Use condition_broadcast, not condition_signal.
+	* pipe.h (pipe_select): New function.
+	
+	* pipe.h (struct pipe): Remove interrupt_seq_num field.
+	(pipe_wait): Use hurd_condition_wait to detect interrupts instead
+	of previous ad-hoc mechanism.
+
+	* pipe.c (pipe_create): Don't initialize interrupt_seq_num field.
+
+	* pipe.h (pipe_acquire_reader, pipe_acquire_writer,
+	pipe_add_reader, pipe_add_writer): `aquire' -> `acquire'.
+
+Fri Aug 11 18:35:32 1995  Miles Bader  <miles@churchy.gnu.ai.mit.edu>
+
+	* pipe.c (pipe_create): Initialize READERS & WRITERS, not REFS.
+	(_pipe_first_writer): New function.
+	(_pipe_no_writers, _pipe_no_writers): New function.
+	(pipe_break): Function deleted.
+
+Wed Aug  9 12:53:05 1995  Miles Bader  <miles@geech.gnu.ai.mit.edu>
+
+	* pipe.h (struct pipe): Keep separate ref counts for readers and
+	writers.
+	(pipe_aquire_reader, pipe_aquire_writer): New functions.
+	(pipe_release_reader, pipe_release_writer): New functions.
+	(pipe_add_reader, pipe_add_writer): New functions.
+	(pipe_remove_reader, pipe_remove_writer): New functions.
+	(_pipe_first_writer): New function decl.
+	(_pipe_no_writers, _pipe_no_writers): New function decl.
+	(pipe_aquire, pipe_release): Function deleted.
+	(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 control packet if there is no data packet,
+	since pipe_write always writes a data packet.
+
+Mon Jul 31 14:50:00 1995  Miles Bader  <miles@churchy.gnu.ai.mit.edu>
+
+	* pipe.c (pipe_recv): Assert that 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'.
