	* src/isc_relocate.c (isc_relocate_fd): Implemented for real.
	* src/isc_event.c (isc_getnextevent): Return
	ISC_EVENT_LOGIN_UNRELOCATED instead of ISC_EVENT_LOGIN if a
	file descriptor relocation failed.
	* src/isc.h (IscEventType): New event: ISC_EVENT_LOGIN_UNRELOCATED.

1999-04-17  Per Cederqvist  <ceder@gratia>

	Added limited support for fd relocation.  Error handling still
	needed.
	* src/isc_udp.c (isc_createudp): Relocate the fd.
	* src/isc_tcp.c (isc_tcp_accept_fn): isc_createtcp will close the
	file descriptor if it fails, so don't re-close it here.
	isc_createtcp will also set the fd attribute of the session; don't
	set it again.
	(isc_createtcp): Relocate the fd.  Be careful to always close it
	if an error occurs.
	* src/isc_relocate.c (isc_relocate_fd): New file and function.
	This is still a dummy implementation.
	* src/isc_master.c (isc_initialize): Expect master config version
	1006 and session config 1002.  Handle fd_relocate.
	* src/isc.h (IscSessionConfig): Added fd_relocate.
	* src/intern.h (isc_relocate_fd): New function.
	* src/Makefile.am (libisc_a_SOURCES): Added isc_relocate.c.

1999-04-16  Per Cederqvist  <ceder@gratia>

	Simplify the use of IscHandlerList.  (This needs more
	documentation.)
	* src/isc.h (IscSession): Removed the "IscHandlerCache fun"
	member.
	(ISC_HCALLFUN1): Adapted to IscHandlerList changes.
	(ISC_HCALLFUN2): Adapted to IscHandlerList changes.
	(ISC_HCALLFUN3): Adapted to IscHandlerList changes.
	* src/intern.h (ISC_SCALLFUN1): Use ISC_HCALLFUN1 to simplify
	code.  Adapted to IscHandlerList changes.
	(ISC_SCALLFUN2): Analogous.
	(ISC_SCALLFUN3): Analogous.
	* src/isc_handler.c (isc_pushhandler): Modified so that the
 	members of the member "current" of IscHandlerList objects points
 	to the IscHandler object where the callbacks that should be used
 	exist.  Once that changes was done, there is no need for the
 	"scb->fun" member, so it was removed.
	(isc_pophandler): Adjusted accordingly.
	* src/isc_session.c (isc_create): Removed the code that
	initialized scb->fun.
	(isc_destroy): Use scb->handlers->current instead of scb->fun.
	* src/isc_event.c (isc_getnextevent): Use scb->handlers->current
	instead of scb->fun.

1999-04-15  Per Cederqvist  <ceder@lysator.liu.se>

	Allow disabled sessions to emit data.  It is input from the
	sessions that is disabled.
	* src/isc_stdout.c (isc_putc): Allow output to sessions that are
	in state ISC_STATE_DISABLED.
	(isc_write): Likewise.
	* src/isc_output.c (isc_flush): Flush pending output even
	when the session is in ISC_STATE_DISABLED.
	(isc_oflush): Likewise.
	* src/isc_event.c (isc_getnextevent): Flush pending output even
	when the session is in ISC_STATE_DISABLED.

	The LysKOM server should not install isc thingies.
	* src/Makefile.am (noinst_LIBRARIES, noinst_HEADERS): Use instead
	of lib_LIBRARIES and include_HEADERS so that nothing from isc gets
	installed by lyskomd.

1998-06-21  Per Cederqvist  <ceder@lysator.liu.se>

	Incorporated all relevant improvements made to ISC in
	the committed sources of lyskomd as of 1998-06-21.  Edited details
	follows.

	Include file improvements.
	* src/isc_event.c: Include <sys/select.h>, <unistd.h> and
	<string.h> for increased portability.
	* src/printf.c: Check HAVE_STRING_H and HAVE_STDLIB_H before
	including those files.  Don't forward-declare memchr.

	Ignore attempts to look up the NULL host name.
	* src/isc_socket.c (isc_gethostname): Return NULL if given a NULL
	IscAddress.

1998-05-07  Per Cederqvist  <ceder@lysator.liu.se>

	Incorporated all relevant improvements made to ISC in
	kom++-0.7.post.2.  Edited details follows.
	
	Avoid including more files than necessary.
	* src/isc.h: Don't include any include files.
	* src/isc_abort.c: Don't declare system functions.  Fixed include
	statements.
	* src/isc_alloc.c: Likewise.
	* src/isc_event.c: Likewise.
	* src/isc_message.c: Likewise.
	* src/isc_output.c: Likewise.
	* src/isc_session.c: Likewise.
	* src/isc_socket.c: Likewise.
	* src/isc_stdout.c: Likewise.
        * src/isc_tcp.c: Likewise.
	* src/isc_udp.c: Likewise.
	* src/isc_handler.c: Fixed include statements.
	* src/isc_master: Likewise.
	* src/isc_queue.c: Likewise.

	Added the ability to wait until a connection attempt (initiated by
	this process) either fails or succeeds.
	* src/isc.h: (isc_wait): Prototype added.
	* src/isc_wait.c: New file, containing isc_wait.

	Only support isc_printf and isc_vprintf if ISC_PRINTF_SUPPORT if
	defined.  These functions may lead to bad use of the buffers.
	* src/isc.h: (isc_vprintf, isc_printf): Only declare if
	ISC_PRINTF_SUPPORT is defined.  Fail to compile if
	ISC_PRINTF_SUPPORT is defined but HAVE_STDARG_H isn't.
 	* src/isc_stdout.c (send_scb, send_putc, isc_vprintf, isc_printf):
	Only defined if ISC_PRINTF_SUPPORT is defined.

	Make sure that isc_getnextevent only returns a single
	ISC_EVENT_LOGOUT message when a session logs out.
	* src/isc.h: (IscSessionState): New state: ISC_STATE_CLOSING2.
	* src/isc_event.c (isc_getnextevent): There is now only one
	ISC_EVENT_LOGOUT message per session.  Set the state to
	ISC_STATE_CLOSING2 when generating an ISC_EVENT_LOGOUT message.
 	* src/isc_output.c (isc_flush): Treat ISC_STATE_CLOSING2 as
	ISC_STATE_CLOSING.
	(isc_oflush): Likewise.
	
	Portability fixes.
	* src/isc_alloc.c (isc_mallocfn, isc_reallocfn, isc_freefn):
	Removed lame casts.

	Make sure that isc_malloc returns a block that is aligned on a
	"long" boundary.
 	* src/isc_alloc.c (isc_malloc, isc_free, isc_realloc): Portablilty
	fix: Align data on a "long" boundary, not only an "int" boundary.

	Typo fix.
	* src/isc_event.c (isc_getnextevent): Fixed a spelling error in a
	comment.
	
	Make sure that errors are reported to the proper session.
  	* src/isc_event.c (isc_getnextevent): event->session was sometimes
	set erronously if an error occured in select() or if a timeout
	occured.

	Use O_NONBLOCK instead of the now obsolete name FNDELAY.
	* src/isc_session.c (isc_openfd): Use O_NONBLOCK instead of FNDELAY.
	* src/isc_tcp.c (isc_createtcp): Use O_NONBLOCK instead of FNDELAY.
	* src/isc_udp.c (isc_createudp): Use O_NONBLOCK instead of FNDELAY.

	Avoid warnings by adding a dubious cast.
 	* src/isc_socket.c (isc_gethostname): Cast argument to
	gethostbyaddr to a char* to avoid a warning.
	
	Portability fix: Renamed _printf to UCB_printf.
	* src/isc_stdout.c (isc_printf, isc_vprintf): Call UCB_printf
	instead of _printf.
	* src/printf.c (UCB_printf): Renamed _printf to UCB_printf (to avoid
	conflicts on HPUX).

	Don't use obsolete setsockopt interfaces.
	* src/isc_tcp.c (isc_createtcp): Fixed calls to setsockopt with
	SO_LINGER and SO_REUSEADDR arguments.  The old-style style
	previously used should no longer be necessary on modern operating
	systems, and in fact it no longer works everywere.  
	* src/isc_udp.c (isc_createudp): Fixed calls to setsockopt with
	SO_LINGER and SO_REUSEADDR arguments.  The old-style style
	previously used should no longer be necessary on modern operating
	systems, and in fact it no longer works everywere.  

	If an attempt to bind failed with EADDRINUSE all the retries
	would automatically fail.
	* src/isc_tcp.c (isc_listentcp): Clear errno on each loop in the
	retry loop.

	Include the licensing conditions used by this package.
	* COPYING: New file.

1998-04-03  Per Cederqvist  <ceder@signum.se>

	Port to glibc 2, where errno is a macro.
	* isc.h (IscSession::isc_errno): New name for former struct member
	errno.  All users updated.

1996-07-24  Per Cederqvist  <ceder@lysator.liu.se>

	ISC_EVENT_LOGIN events now return the listening session in the
	event, so that it can be used to easily determine which kind of
	connection that was made.  66.7 % of the code was contributed by
	<linus@lysator.liu.se>.
	* src/isc.h (IscEvent): New field: listen_session.
	* src/isc_event.c (isc_getnextevent): Fill in listen_session when
	an ISC_EVENT_LOGIN event is created.  Set it to NULL in all other
	cases.

1996-07-23  Per Cederqvist  <ceder@lysator.liu.se>

	* Imported ISC version 0.98.3.
