        * unix/lock.c (fsdo_lock): don't fail if the lock file is removed
        between the link and the open.

        and TLI descriptors.

        * tcp.c (ftcp_open): switch to real user ID before binding the

        by root to open privileged TCP ports.  Don't switch to real ID if
        effective ID is already root, to permit an suid root program to be
        invoked by anybody.

        * uuxqt.c (uqdo_xqt_file): removed special case for system which
        does not permit any commands: unnecessary and unusual.

        glibc 1.04; call malloc instead of alloca in exchange.

        (main), uustat.c (main), cu.c (main), uuname.c (main), unix/init.c

        * uustat.c, uustat.1: Don Phillips: removed all printing of years
        and seconds.  Hope nobody complains.

        * chat.c (fcsend), tstuu.c (uchild): Chip Salzenberg: call sleep
        (2) instead of sleep (1).  Hopefully this won't break any chat
        scripts.

        * system.h, parse.c, trans.c (fqueue, flocal_poll_file), uustat.c
        (fsworkfiles_system, fsquery_system), unix/work.c
        (fsysdep_get_work, fsysdep_get_work_init): don't delete poll files

        the command is passed to fsysdep_did_work.

        * tstuu.c (uprepare_test): change ``call-request'' to ``request''.

        * uuconf/iniglb.c (_uuconf_itimetable): return CMDTABRET_KEEP so
        we don't lose the timetable name and definition.

        specify the file base name in the TO argument.

        * uucico.c (main): Don Lewis: don't exit with success just because
        we were able to start uuxqt.

        * unix/serial.c (fsmodem_close, fsserial_read): always drop DTR
        when closing a modem connection.  Also, retry if we time out when

        * uuconf/time.c: Stephen Walick: don't require a comma between
        time strings, since HDB doesn't seem to.

        * protg.c (fgcheck_errors): added "error-decay" protocol parameter
        to decay errors as packets are successfully received.

        * uustat.c (fsmachines), uustat.1: Chris Lewis: don't display the
        year or seconds for uustat -m.  Probably uustat -q should be
        changed as well.

        * tstuu.c: Larry Fahnoe: don't report EWOULDBLOCK errors when
        writing to a pty.  Also removed functions which are now in lib.

        unix/xqtfil.c: Brian J. Murrell and Don Phillips: added
        SPOOLDIR_SVR4.

Thu Aug 20 00:06:32 1992  Ian Lance Taylor  (ian@airs.com)

        been received.

Sat Aug 15 11:50:32 1992  Ian Lance Taylor  (ian@airs.com)

        * uuconf/time.c (itadd_span): Don Lewis: fixed bug if later span

        changes to improve performance on a lossy line: can now shrink
        packet size using SYNC packets, avoids multiple bad header errors
        in a sequence of INTRO characters, avoids letting one side lock up
        if a NAK is lost.

        * configure.in: set HAVE_LONG_FILE_NAMES to 0 if
        cross-configuring.

        * tstuu.c: changed -p option to be mod 1000, not mod 100.

        uuconf/hsinfo.c, uuconf/syssub.c: added "max-retries" command for
        systems, eliminated CMAXRETRIES configuration parameter, set

        * unix/work.c (fsysdep_get_work_init): return TRUE if there is no
        work directory.

        * configure.in, sysh.unx: don't run any programs in configure if
        we are cross-configuring; this applies to HAVE_FTIME and
        HAVE_RESTARTABLE_SYSCALLS.  The code can cope with the buggy
        ftime.  If we are cross-configuring, HAVE_RESTARTABLE_SYSCALLS is
        set to -1, and sysh.unx guesses that if the system has sigvec but
        not sigaction or SV_INTERRUPT it is on 4.2BSD and system calls are
        automatically restarted.

        * configure.in, conf.h.in, tstuu.c, unix/serial.c: removed
        COMBINED_UNBLOCK configuration parameter, and changed the code

        (icutake), chat.c (icexpect), lib/MANIFEST: removed all calls to
        memmove, avoiding the SCO bug and making the 'g' protocol slightly
        more efficient.

Sat Jul 25 14:20:30 1992  Ian Lance Taylor  (ian@airs.com)

        * uucp.h, uudefs.h, many other files: broke part of uucp.h out
        into uudefs.h, stopped including uuconf.h in uucp.h, fixed up .c
        files to include uudefs.h and uuconf.h as necessary.

        * uuconf/syshdr.unx, uuconf/callin.c, uuconf/diacod.c
        uuconf/hdial.c, uuconf/hdnams.c, uuconf/hport.c, uuconf/hsinfo.c,

        uuconf/tdnams.c, uuconf/tport.c, uuconf/vport.c, uuconf/vsinfo.c,
        uuconf/vsnams.c: changed uuconf library to not return an error if
        a configuration file does not exist; it now acts as though
        whatever it is is not found.

        lib/MANIFEST, lib/Makefile.in, lib/escape.c, unix/cusub.c,
        unix/serial.c, uuconf/hport.c, uuconf/tportc.c: added support for
        TLI connections.  Moved ccescape from chat.c to cescape in
        lib/escape.c.  Made all connections on Unix use the same
        system dependent structure.

Tue Jul 21 22:08:10 1992  Ian Lance Taylor  (ian@airs.com)

        * uucp.h, trans.h, uucico.c (fdo_call, faccept_call), uuxqt.c

        (ffprocess_data), proti.c (fiprocess_data), tstuu.c
        (uprepare_tests), unix/splcmd.c (zsysdep_spool_commands),
        unix/statsb.c (fskill_or_rejuv), unix/work.c (fsysdep_get_work):
        added E request to send file executions which only require reading
        from standard input.

        points.  Cleaned up send and receive state machines.  Removed
        pfgone argument from esysdep_open_send.

Fri Jul 17 09:41:05 1992  Ian Lance Taylor  (ian@airs.com)

        * uuxqt.c (uqdo_xqt_file): only report base name of execution
        file, not full name.

        a row.

        * uuconv.c (uvwrite_taylor_system, uvwrite_taylor_port): Chris
        Lewis: generate command "protocol", not "protocols".

        * xcmd.c (fremote_xcmd_init): Chris Lewis: use qdaemon->puuconf,

Sat May 30 12:37:02 1992  Ian Lance Taylor  (ian@airs.com)

        * system.h, sys1.unx: changed zsysdep_local_name to
        zsysdep_localname, and made it fatal out rather than return NULL.

        * uuconf.h, uuconf/Makefile.in, uuconf/uucnfi.h, uuconf/iniglb.c,
        uuconf/rdlocs.c, uuconf/locnm.c, uuconf/tlocnm.c, uuconf/hlocnm.c:
        wrote uuconf_localname, uuconf_taylor_localname,

        * sysinf.c (ztranslate_system): Jac Kersing: must xstrdup the

        * copy.c, sys1.unx (usysdep_detach), sys2.unx (fsserial_close),
        sys3.unx, sys5.unx, sys7.unx: opening /dev/tty in usysdep_detach
        confuses the NeXT, so instead we just call TIOCNOTTY on 0.  In
        fsserial_close we call TIOCNOTTY on the port before closing it, to
        make sure that we have ditched it under BSD.  Also added O_NOCTTY
        to every open call other than opening a port, although there are
        still several fopen calls which should probably have it somehow.

        * system.h, uucico.c (fcall), uustat.c (fsquery_system,
        fsquery_show), sys3.unx (fsysdep_get_status), sys7.unx

        * uucico.c, sys1.unx, sys2.unx, sys3.unx, sys5.unx, sys6.unx,
        sys7.unx: Rolf Nerstheimer: cast a bunch of arguments to open,
        creat, stat and chmod to avoid compiler warnings.

        * uucp.h, log.c (ulog), port.c (fport_close), prot.c (fgetcmd):
        Chip Salzenberg: don't log a SIGHUP signal while we're closing
        down the connection, since the other side might hang up faster
        than we do (we still react to it correctly, we just don't put it
        in the log file).

        * sys1.unx (usysdep_detach), tcp.c (ftcp_open): Petri Helenius:
        update the process ID we log after a fork.

        * configure.in, conf.h.in, sys2.unx, tstuu.c: Rob Janssen: look
        for <sys/select.h>, and include it if it exists and we are using
        select.

        * protg.c: Rob Janssen: rearrange macros to avoid bug in XENIX
        compiler.

        * configure.in: Scott Blachowicz: check WIFEXITED before assuming
        HAVE_UNION_WAIT, to avoid problems on HP/UX.

        * configure.in, conf.h.in, sysh.unx, sys1.unx: John Theus: use
        sv_onstack instead of sv_flags in the sigvec structure on 4.2BSD.

        * policy.h, sys2.unx (fsysdep_modem_no_carrier): Scott Reynolds:
        added HAVE_CLOCAL_BUG compilation parameter to work around
        problems on some serial ports.

Tue May 26 15:50:17 1992  Ian Lance Taylor  (ian@airs.com)

        fsysdep_privileged function.

Thu May 21 13:30:21 1992  Ian Lance Taylor  (ian@airs.com)

        case significant; this will change handling of "n" flag, which was
        not correctly handled before.

        (fsysdep_lock_status): force LOCKDIR to always be defined.

        * uucp.h: put in an extern for alloca.

        * sysh.unx, sys1.unx, sys5.unx, sys6.unx: defined all the ?_OK
        macros in sysh.unx, which means that <unistd.h> must be included
        before "sysdep.h" when they are both included.

        * sys2.unx (fsserial_set): corrected case in termio switch
        expression.

        * policy.h: David J. MacKenzie: various cleanups.

Thu Mar 26 12:17:41 1992  Ian Lance Taylor  (ian@airs.com)

        * sys3.unx: reduced race condition in fsdo_lock.

        * sys1.unx: Gerben Wierda: various cleanups.  Also don't set
        sa_flags to SV_INTERRUPT per Chip Salzenberg.

Wed Mar 25 22:20:24 1992  Ian Lance Taylor  (ian@airs.com)

        * configure.in: Overhauled for readability and functionality as
        suggested by T. William Wells and others.  Added bug checks,
        including for SCO memmove and ftime.

        * sysinf.c (uiread_systems): fixed handling of alternates in
        file-wide defaults.

        * config.c (tprocess_one_cmd): handle CMDTABTYPE_FULLSTRING
        correctly if there are no arguments.

        * Released beta version 1.03

        * sys1.unx (usysdep_detach): open the controlling terminal in non
        delay mode since it might be a modem.

Tue Mar 17 00:01:53 1992  Ian Lance Taylor  (ian@airs.com)

        * uucico.c (fdo_call, faccept_call): T. William Wells: set current
        time in status file when call completes.

        * sys1.unx (iswait), sys2.unx (fsserial_read, fsserial_write,
        fsserial_io): log signals when they occur, even if we continue
        some sort of loop, rather than waiting for the next ulog call.

        * sys2.unx (fsserial_lock, fsserial_open): don't block when
        opening the write descriptor.

Mon Mar 16 00:14:43 1992  Ian Lance Taylor  (ian@airs.com)

        * system.h, uuxqt.c (uqdo_xqt_file), sys5.unx (fsysdep_execute):
        pass command to fsysdep_execute as first element of argument
        array.

        * tcp.c: declare _exit.

        * uucp.h: move definition of const before use for non ANSI C.

        * uucp.h, sys1.unx: undefine remove in uucp.h if the system does
        not have it to avoid conflict with macro definitions.

        * uucico.c, uuxqt.c, protf.c, prott.c, prote.c, config.c, chat.c,
        port.c, sys2.unx: miscellaneous cleanups.

        * tcp.c (ftcp_open): cast argument to bzero.

        * time.c (qtimegrade_parse): cast argument to qttime_parse to
        long.

        * file.c: changed iRecmode to unsigned int.

        * configure.in, uucp.h: on SCO 3.2.2 sig_atomic_t is defined in
        <sys/types.h> but not <signal.h>.

        * sys1.unx: undefined remove before the function definition to
        avoid trouble on systems for which it is a macro.

        * Makefile.in: removed dependencies of getopt.o.

        * sys1.unx, sys7.unx, tstuu.c: adjusted external declarations.

        * getopt.h, getopt.c: get new versions from glibc 1.01.

        * sys1.unx: don't declare sigemptyset.

        * version.c: updated to beta 1.03.

        * chat.c (fcsend): Scott Ballantyne: go ahead and send a character
        for an illegal escape sequence rather than failing out.

        * uuxqt.c (uqdo_xqt_file), sys5.unx (zsysdep_find_command): cast
        result of alloca.

        * protg.c (fgprocess_data): Niels Baggesen: improved debugging
        information.  Also tweaked fgprocess_data code to use memchr to
        find the next DLE rather than searching for it by hand.

        * uucico.c (faccept_call, fuucp): accept SVR4 -U flag giving
        maximum file transfer size; accept and ignore SVR4 -R flag meaning
        that the system supports file restart.

Sun Mar 15 00:21:56 1992  Ian Lance Taylor  (ian@airs.com)

        * sysinf.c (titime, titimegrade): permit a retry time to be
        specified as an optional additional argument.

        * uucico.c (zget_uucp_cmd, zget_typed_line): turn off DEBUG_PORT
        when doing DEBUG_HANDSHAKE.

        * policy.h, sysh.unx, sys1.unx, sys2.unx (fsblock_writes,
        fsserial_write, fsserial_io): added configuration parameters
        HAVE_UNBLOCKED_WRITES and SINGLE_WRITE.  Also blocked signals
        while clearing afSignal in fsysdep_modem_close.

        * chat.c (icexpect, fcsend): turn off DEBUG_PORT while doing chat
        script debugging.

        * sysh.unx, sys2.unx (fsserial_lock, fsserial_open,
        fsserial_write, fsserial_io, fsysdep_tcp_read, fsysdep_tcp_write,
        fsysdep_tcp_io): T. William Wells: some systems don't support
        unblocked writes, so don't use them.

        * port.c (fport_read, fport_write): show calls to fport_read and
        fport_write under DEBUG_PORT.

        * bnu.c (fbnu_find_port): Scott Ballantyne: accept "Any" as a
        Device speed.

Sat Mar 14 20:52:11 1992  Ian Lance Taylor  (ian@airs.com)

        * uucp.h, system.h, sysh.unx, uucico.c (main, zget_typed_line),
        uuxqt.c (main), uucp.c (main), uux.c (main, uxcopy_stdin), tcp.c
        (ftcp_open), log.c (ulog, ulog_close), sys1.unx (ussignal),
        sys2.unx (fsserial_close, fsysdep_modem_end_dial, fsserial_read,
        fsserial_write, fsserial_io, fsysdep_tcp_read, fsysdep_tcp_write,
        fsysdep_tcp_io): T. William Wells and Chip Salzenberg: keep an
        array of signals so that a new signal doesn't obliterate our
        knowledge of an old signal.  Johan Vromans: if we get SIGINT
        continue the current session but don't start any new ones.

        * sysh.unx, sys1.unx (isspawn, espopen, iswait, fsysdep_mail,
        fsysdep_run, getcwd, mkdir), sys2.unx (fsrun_chat), sys3.unx
        (fsysdep_wildcard_start), sys5.unx (fsysdep_execute), sys7.unx
        (fsysdep_lock_status), uuxqt.c (uqdo_xqt_file), tcp.c (ftcp_open),
        tstuu.c (uchild): added function isspawn, espopen and iswait and
        channeled all execs of new processes and waits through them.

Fri Mar 13 18:00:04 1992  Ian Lance Taylor  (ian@airs.com)

        * sysinf.c (uset_system_defaults): Chip Salzenberg: changed
        default login script timeout to 10 seconds.

        * prot.h, prot.c (freceive_data, breceive_char), protg.c, protf.c,
        prott.c, prote.c: changed breceive_char to go through
        freceive_data rather than calling fport_read directly.  Added an
        freport argument to freceive_data, and change all old calls to
        pass it in as FALSE.

Thu Mar 12 14:49:59 1992  Ian Lance Taylor  (ian@airs.com)

        * uucp.h: added a padding byte to scmd structure, since at least
        one compiler needs it.

        * uucp.c (main): use fake local name (from ``myname'' command)
        when generating an execution request intended for the local
        system.

        * sysh.unx: corrected readdir prototype.

        * sys2.unx: moved local header files ahead of sleep routine
        determination.

        * General overhaul to change debugging system.  Debugging is now
        done by type rather than by number.  iDebug is now interpreted as
        a bit sequence.  DEBUG may only be 0 (no checks or debugging), 1
        (checks, no debugging) or 2 (checks and debugging).  The debugging
        names are parsed by idebug_parse and tidebug_parse in config.c.
        The debugging types are additive.  Many source files changed.
        Inspired by Michael Richardson, Johan Vromans and Peter da Silva.

Wed Mar 11 12:01:03 1992  Ian Lance Taylor  (ian@airs.com)

        * policy.h, uuxqt.c (uqdo_xqt_file): Chip Salzenberg: support
        Internet mail addresses in uuxqt replies (added configuration
        parameter HAVE_INTERNET_MAIL to control this).

        * uucp.h, system.h, sysh.unx, config.c, uuxqt.c (main, uqabort),
        sys5.unx (isysdep_lock_uuxqt, fsysdep_unlock_uuxqt), bnu.c
        (ubnu_read_sysfiles): Marty Shannon: added max-uuxqts command,
        along with support for BNU Maxuuxqts, to limit number of
        concurrent uuxqt processes.

        * chat.c (icexpect, fcsend), uucico.c (zget_uucp_cmd,
        zget_typed_line): improved debugging by avoiding incredibly long
        lines.

        * system.h, sys5.unx (fsysdep_execute), uuxqt.c (uqdo_xqt_file):
        Jon Zeef: if a temporary failure occurs, retry the execution
        later.

Tue Mar 10 12:40:30 1992  Ian Lance Taylor  (ian@airs.com)

        * sysh.unx, sys1.unx (isfork), sys2.unx, sys5.unx, tcp.c:
        Franc,ois Pinard: retry fork several times before giving up.

        * uucp.h, prot.c (fploop, fgot_data), file.c (usendfile_error,
        urecfile_error, frecfile_rewind): Niels Baggesen: if we can't read
        or write a file, treat it as a temporary error rather than a
        permanent error; if we get an error on write, drop the connection
        rather they try to continue.

        * uucp.h, system.h, sysh.unx, uucico.c (fuucp), prot.c
        (fsend_file, freceive_file), file.c (fsent_file, usendfile_error,
        freceived_file, urecfile_error, fmail_transfer), sys1.unx
        (usmake_spool_dir), sys4.unx (zsysdep_save_temp_file): if a file
        send fails, save the file away rather than lose it forever.

        * uucico.c (main): don't run uuxqt if we got a SIGTERM.

        * tcp.c (ftcp_open): Petri Helenius: have server fork twice to
        avoid zombies.

        * port.h, prtinf.c, v2.c, bnu.c (fbnu_find_port), uucico.c
        (fdo_call, faccept_call), uuchk.c (fkshow_port): added protocol
        command for ports, mostly to support BNU.  Also modified uuchk to
        make the absence of any matching port or dialer more obvious.

        * sys3.unx (esysdep_open_receive): check size of destination file
        system as well as temporary file system; handle f_bsize field
        under FS_MNTENT.

        * configure.in, sysh.unx: test for including <termios.h> and
        <sys/ioctl.h> in the same file, setting new configuration
        parameter HAVE_TERMIOS_AND_SYS_IOCTL_H accordingly; handle it in
        sysh.unx.

Mon Mar  9 00:06:12 1992  Ian Lance Taylor  (ian@airs.com)

        * sys2.unx (fsserial_close): Franc,ois Pinard: sleep for a second
        after closing the serial port to give it a chance to settle.

        * sysh.unx (fsetterminfodrain), sys2.unx (fsserial_close,
        fsserial_reset, fsserial_set): wait for terminal output to drain
        before closing it, resetting it, or changing its parameters.

        * uucico.c (zget_uucp_cmd): Ted Lindgreen: strip parity bit from
        initial handshake strings.

        * system.h, sys3.unx (esysdep_open_send), uucico.c (fuucp): Ted
        Lindgreen: don't send a mail message if a file to send has been
        removed, since it might have been sent in a previous session.

        * uuchk.c (ukshow): Zacharias Beckman: put list of permitted
        programs and execution path on separate lines.

        * uucico.c (fdo_call, faccept_call): only look for hangup string
        in debugging mode, since there's nothing to be done with it
        anyhow.

        * uucico.c (faccept_call): Ted Lindgreen: report the minimum
        transfer grade requested during an incoming call in the log file.

        * uucp.h, uutime.h, config.c, uucico.c (fcall), time.c
        (ftimespan_match, btimegrade, cmax_size_now): added a new status
        type for ``wrong time to call''.  If a system can never be called,
        this status type is not used (if an attempt is made to call the
        system, the status is left unchanged).

Sun Mar  8 11:41:45 1992  Ian Lance Taylor  (ian@airs.com)

        * uucico.c (main, flogin_prompt, faccept_call): Ted Lindgreen: if
        we were asked to call a single system, or if a single system
        called in, then start uuxqt with -s for just that system.

        * uucico.c (main): Ted Lindgreen: ignore the -u option.

        * tstuu.c: Ted Lindgreen: don't include <sys/ioct.h> if it's not
        there.  Also removed the ``ignore this error'' message from the
        chat scripts since it's no longer marked as an error.

        * sys2.unx (fsserial_set): Ted Lindgreen: if CRTSCTS is defined
        and turned on, then don't turn on IXOFF.

        * uucp.h, log.c, uucico.c (fdo_call, faccept_call): Ted Lindgreen:
        report the port name and (for incoming calls) the login name in
        the log file.

Sat Mar  7 10:00:47 1992  Ian Lance Taylor  (ian@airs.com)

        * port.h, prtinf.c, sys2.unx (fsserial_lockfile, fsserial_lock):
        Peter da Silva: added ``lockname'' command to ports to permit
        specification of the file name to use when locking.

        * sys1.unx (usysdep_detach): let setpgrp fail silently.

        * sys2.unx: always include <sys/ioctl.h> if it's present on the
        system.

        * time.c (btimegrade, cmax_size_now): removed extraneous
        semicolons.

        * sys2.unx (fsserial_lock, fsserial_open, fsserial_close): support
        TIOCEXCL locking.

        * sys2.unx (fsserial_open): preserve unknown bits in c_cflag when
        using HAVE_SYSV_TERMIO or HAVE_POSIX_TERMIOS.

        * prot.h: never included more than once.

Fri Mar  6 21:53:28 1992  Ian Lance Taylor  (ian@airs.com)

        * uucp.h: Eric Ziegast: some systems don't define EXIT_SUCCESS or
        EXIT_FAILURE in stdlib.h.

        * uucp.h, uutime.h, uucico.c (fuucp), sysinf.c (uinittimetables,
        uaddtimetable), uuchk.c (main, ukshow_size, ukshow_time,
        qcompress_span), time.c (all new): rewrote time routines
        completely for consistency and simplicity.  Fixed bug causing
        incorrect maximum possible transfer size.  Added new file
        uutime.h.

Wed Mar  4 10:06:13 1992  Ian Lance Taylor  (ian@airs.com)

        * sys2.unx (fsserial_lockfile, fsserial_lock, fsysdep_modem_open,
        fsysdep_direct_open, fsysdep_modem_close, fsysdep_direct_close):
        Petri Helenius: if the open failed on a serial port, the lock
        files were not removed.

        * config.c (igradecmp): the local variables in igradecmp have to
        be integers; signed characters might not work correctly (although
        they would in all normal cases).

        * sys4.unx (fsysdep_has_work): Johan Vromans: set *pbgrade
        correctly if we still have work left over that we haven't looked
        at yet.

        * tstuu.c (main, uchoose, fwriteable): Roberto Biancardi: use poll
        if we haven't got select.

        * uucico.c (zget_uucp_cmd): Michael Haberler: some systems send \n
        after Shere, rather than a null byte.

Tue Mar  3 01:03:22 1992  Ian Lance Taylor  (ian@airs.com)

        * uuxqt.c (main, uqdo_xqt_file): permit local executions, don't
        get grade out of system dependent file name.

        * sys4.unx (fsysdep_get_work): Bob Denny: warn if we can't open a
        command file.

        * v2.c (uv2_read_systems): Jeff Putsch: infinite loop when reading
        time string.

        * uucp.h, sys1.unx, sys2.unx, sys3.unx, tstuu.c, configure.in:
        Thomas Fischer: some NeXT compatibility stuff: removed externs of
        sleep and alarm, included <libc.h> in uucp.h.

        * uucp.h, port.h, uucico.c (zget_uucp_cmd, zget_typed_line),
        port.c (cdebug_char, udebug_buffer), chat.c (icexpect, fcsend,
        fcphone), log.c (ulog): Michael Richardson: added LOG_DEBUG_START,
        LOG_DEBUG_CONTINUE and LOG_DEBUG_END to allow a debugging line in
        the log file to be built character by character.  Used this new
        feature in chat script debugging, rather than having each
        character appear on a separate line.  Added fPort_debug variable
        to control port debugging.

        * uustat.c (fsquery, fsquery_system, fsquery_show): handle
        execution files queued up for the local system correctly when
        using -q option (they still don't show up on any other option).

        * uucp.texi, protg.c (fgstart, fgshutdown): Aleksey P. Rudnev:
        added remote-window and remote-packet-size 'g' protocol
        parameters.  Reset the parameters to their default values in
        fgshutdown.

        * sysh.unx, sys2.unx (fsserial_read, usalarm), sys1.unx
        (usset_signal, usysdep_detach), uucico.c (main): overhauled
        fsserial_read yet again.  The timeout passed in is now an absolute
        bound.  A special SIGALRM handler does some wierd stuff to avoid
        any possible race.

        * config.c (uread_config), sysinf.c (uiread_systems,
        fcallout_login, fcheck_login), prtinf.c (ffind_port,
        fread_dialer_info), chat.c (fctranslate), uucico.c (faccept_call):
        T. William Wells: when using HAVE_TAYLOR_CONFIG in combination
        with V2 or BNU configuration files, don't complain if the
        HAVE_TAYLOR_CONFIG files are missing.

Mon Mar  2 10:21:36 1992  Ian Lance Taylor  (ian@airs.com)

        * sys2.unx (fsserial_read): T. William Wells: don't arbitrarily
        extend read timeout.

        * uux.c (main): check iSignal before entering fread, since the
        user may have hit ^C earlier in the program.

Sun Mar  1 23:39:33 1992  Ian Lance Taylor  (ian@airs.com)

        * policy.h, uucp.h, sysh.unx, sys2.unx (fsserial_lock,
        fsysdep_modem_close, fsysdep_direct_close), util.c (strlwr),
        configure.in: Marc Unangst: added HAVE_SCO_LOCKFILES configuration
        parameter to force lock file names to lower case.

Fri Feb 28 00:07:12 1992  Ian Lance Taylor  (ian@airs.com)

        * system.h, uucico.c (faccept_call, fdo_xcmd), uuxqt.c
        (uqdo_xqt_file), uux.c (main), uucp.c (main, ucspool_cmds),
        sys3.unx (zsysdep_spool_cmds), uux.1, uucp.1: added -j switch to
        uucp and uux to display the jobid of the spooled job.

        * uucp.h, system.h, sysh.unx, uucico.c (fuucp, fdo_xcmd,
        fok_to_send, fok_to_receive), uuxqt.c (uqdo_xqt_files), uux.c
        (main, uxcopy_stdin), uucp.c (main), file.c (freceived_file),
        config.c (fin_directory_list), sys1.unx (fsysdep_file_exists,
        fsuser_access, fsysdep_in_directory), sys3.unx (esysdep_open_send,
        fsysdep_move_file), sys5.unx (fsysdep_xqt_check_file): Chip
        Salzenberg: recheck file access permissions before sending, to try
        to avoid symbolic link games.  Check that the user has search
        access on all directories down to the file, and read or write
        access to the file or directory itself.  Check in uucp and uux as
        well as uucico, to provide early messages.  Check the standard
        input file in uuxqt.  Be more careful about creating files in the
        spool directory.  This eliminates all security problems I know of,
        except for a very short race in fsysdep_move_file.

        * sys3.unx (esysdep_open_send): give an error message if we try to
        send a directory (used to just fail silently).

        * system.h, sysh.unx, sys1.unx (usysdep_detach, ussignal,
        fsysdep_catch, usysdep_start_catch), sys2.unx
        (fsysdep_modem_end_dial, fsserial_read), uux.c (main): T. William
        Wells: fsysdep_catch obviously must be a macro, since it calls
        setjmp.  Also TIOCNOTTY sets the process group to 0, so we don't
        have to fork before calling it.

Thu Feb 27 00:08:09 1992  Ian Lance Taylor  (ian@airs.com)

        * sys1.unx, sys6.unx, sys7.unx: added some extern definitions.

        * configure.in, uucp.h, system.h, sysh.unx, uucico.c (main,
        ucatch, uabort, zget_typed_line, zget_uucp_cmd), uuxqt.c (main,
        uqcatch, uqabort), uux.c (main, uxcatch, uxrecord_file, uxabort),
        uucp.c (main, uccatch, ucrecord_file, ucabort), uustat.c (main,
        uscatch), uulog.c (main, ulcatch), uuname.c (main, uncatch),
        uucheck.c (main, ukcatch), log.c (ulog_fatal_fn, ulog,
        ulog_close), tstuu.c (main, uchild, uprepare_test), sys1.unx
        (usysdep_initialize, usysdep_detach, usysdep_signal,
        fsysdep_catch, usysdep_end_catch, ussignal, fsset_signal,
        fsysdep_run, raise), sys2.unx (usalarm, usysdep_pause,
        fsserial_lock, fsserial_open, fsysdep_stdin_close,
        fsysdep_modem_close, fsysdep_modem_end_dial, fsserial_read,
        fsserial_write, fsserial_io), sys5.unx (fsysdep_execute): T.
        William Wells: overhaul to support detaching from the terminal and
        completely reliable signals.  uucico now calls usysdep_detach at
        various points; new option -D prevents detaching.  The signal
        handling code all goes through usysdep_signal, fsysdep_catch and
        usysdep_end_catch.  A signal now just sets iSignal, which is
        checked at various points, notably in the port routines and in the
        main loops in uucico and uuxqt.

Tue Feb 25 10:59:23 1992  Ian Lance Taylor  (ian@airs.com)

        * protg.c (fgwait_for_packet): Bob Denny: reset the count of
        timeouts only when data is recognized, so that we aren't fooled by
        a sequence of imperfect echoes.

        * sys5.unx (zsysdep_get_xqt): Bob Denny: don't warn if opendir
        gets ENOENT.  I think POSIX requires ENOTDIR, but what can you do?

Mon Feb 24 14:37:10 1992  Ian Lance Taylor  (ian@airs.com)

        * uucico.c (main, uusage): don't treat an extra argument as a port
        name.

        * sys3.unx (esysdep_truncate): Roberto Biancardi: support F_CHSIZE
        and F_FREESP in esysdep_truncate.

        * configure.in, sys2.unx (fsserial_read, usysdep_pause): Roberto
        Biancardi: use poll to sleep less than a second if we haven't got
        anything else.

        * v2.c (uv2_read_systems, fv2_find_port), bnu.c
        (ubnu_read_systems, fbnu_find_port, fbnu_read_dialer_info),
        uustat.c (fsworkfile_show): Roberto Biancardi: skip spaces and
        tabs after doing a strtok ((char *) NULL, "").

        * copy.c (fcopy_file), sys1.unx (esysdep_fopen), sys2.unx,
        sys3.unx (esysdep_open_receive, esysdep_truncate, fsdo_lock,
        fscmd_seq), sys5.unx (fsysdep_execute), sys7.unx, tstuu.c: John
        Theus: some systems use <sys/file.h> instead of <fcntl.h>.  Also
        changed the code to call creat instead of open when appropriate.
        Should now work on V7, with the exception of O_NONBLOCK and
        O_NDELAY in sys2.unx and tstuu.c.

        * uucp.h: John Theus: if we don't have vprintf, ulog is defined
        without an ellipsis, so don't declare it with one.

Sun Feb 23 14:45:53 1992  Ian Lance Taylor  (ian@airs.com)

        * uucp.h, system.h, bnu.c (ubnu_read_systems), config.c
        (fin_directory_list), sys1.unx (fsysdep_in_directory), sys5.unx
        (fsysdep_xqt_check_file), uucp.c (main), uuxqt.c (uqdo_xqt_file),
        uucico.c (fdo_xcmd, fok_to_send, fok_to_receive), tstuu.c
        (uprepare_test): only permit files to be received into directories
        that are world writeable.  Check for this in fsysdep_in_directory,
        with a new argument.  Changed calls appropriately.  In tstuu
        create /usr/tmp/tstuu as world writeable.

        * bnu.c (ubadd_perm_alternate): Doug Evans: after all that, I got
        it wrong: WRITE only applies to remote requests.

        * uucp.h, uucico.c (fuucp, fdo_xcmd, fok_to_send, fok_to_receive),
        uuxqt.c (uqdo_xqt_file), uuchk.c (ukshow), sysinf.c
        (uset_system_defaults, tialternate), sys5.unx
        (fsysdep_xqt_check_file), bnu.c (ubadd_perm_alternate): fixed READ
        and WRITE handling to match BNU semantics.  Added
        zcalled_local_send, zcalled_local_receive, zcalled_remote_send and
        zcalled_remote_receive fields to ssysteminfo structure for this,
        and handled them in all the appropriate places.

Sat Feb 22 22:30:59 1992  Ian Lance Taylor  (ian@airs.com)

        * Complete overhaul of configuration to use automatic shell
        script.  Eliminated conf.h, now generated by configure.  Renamed
        Makefile to Makefile.in.  Added policy.h for administrative
        decisions and other choices which can not be made automatically.
        Many changes to many source files, none having to do with code.

Thu Feb 20 17:57:55 1992  Ian Lance Taylor  (ian@airs.com)

        * uucico.c (fdo_call): Chip Salzenberg: some systems truncate the
        Shere= machine name to 7 characters.

Wed Feb 19 14:36:31 1992  Ian Lance Taylor  (ian@airs.com)

        * sys7.unx (fskill_or_rejuv): make sure that only the submitter or
        the superuser is permitted to cancel (or rejuvenate) a request.

        * system.h, sysh.unx, sys3.unx (zsfile_to_jobid, zsjobid_to_file),
        sys4.unx (zsysdep_jobid), sys7.unx, uustat.c, Makefile, MANIFEST:
        wrote uustat.  Changed CSEQLEN in sys3.unx from 5 to 4.  Added
        several new system dependent functions, mostly in sys7.unx.

        * system.h, sys1.unx, log.c, file.c, chat.c, protg.c, uucico.c:
        rearranged the time functions for the convenience of uustat.  Made
        isysdep_time take an optional pimicros arguments.  Renamed
        usysdep_full_time to isysdep_process_time, and made clear that it
        need only work within a single process.  Changed usysdep_localtime
        to take a time returned by isysdep_time rather than always use the
        current time.  Changed the calls as appropriate.

Tue Feb 18 14:03:19 1992  Ian Lance Taylor  (ian@airs.com)

        * uuxqt.c (main): pass fdaemon argument correctly to
        usysdep_initialize.

Mon Feb 17 17:09:16 1992  Ian Lance Taylor  (ian@airs.com)

        * uuxqt.c (uqdo_xqt_file): T. William Wells: make sure sh uses
        absolute path of command, rather than relying on PATH.

        * sys5.unx (zsysdep_find_command): Michael Nolan: allow full
        command name to be specified by remote system, not just basename,
        if command is not in path.

        * log.c (ulog): don't use headers when outputting to terminal.

        * sys2.unx (fsrun_chat): Bob Denny: log chat program messages as
        LOG_NORMAL, not LOG_ERROR.

Fri Feb 14 00:17:57 1992  Ian Lance Taylor  (ian@airs.com)

        * uucico.c (ucatch), uuxqt.c (uqcatch): Neils Baggesen: under
        HAVE_BNU_LOGGING, don't lose the system name when dieing.

        * uulog.c, Makefile, MANIFEST: wrote uulog.

        * uuname.c, Makefile, MANIFEST: wrote uuname.

        * bnu.c (ubadd_perm_alternate): T. William Wells: must xstrdup the
        system name before calling uadd_validate.

        * log.c (ulog_close): Micheal Nolan: don't refer to eLdebug if the
        DEBUG configuration parameter is 0.

        * uucp.c (main): Niels Baggesen: abtname must be copied into
        memory, or it will be overwritten by the next file to be copied.

Sun Feb  9 00:12:58 1992  Ian Lance Taylor  (ian@airs.com)

        * uucico.c (fuucp), prot.c (fsend_file, freceive_file): Bob Denny:
        call fmail_transfer before calling fsysdep_did_work, because the
        latter frees up strings used by the former.

        * sysh.unx, sys1.unx (mkdir), uudir.c (new file), Makefile: added
        HAVE_MKDIR configuration parameter for systems without the mkdir
        system call.  The emulation function in sys1.unx invokes the new
        suid program uudir which sets its uid to uucp and invokes
        /bin/mkdir.  Added rules to create uudir to Makefile.

Sat Feb  8 14:25:50 1992  Ian Lance Taylor  (ian@airs.com)

        * sysh.unx, sys1.unx (opendir, readdir, closedir), sys4.unx,
        sys5.unx: added HAVE_OLD_DIRECTORIES configuration parameter to
        support systems without opendir/readdir/closedir which use
        original Unix directory format.

        * sysh.unx, sys1.unx (dup2): added HAVE_DUP2 configuration
        parameter and dup2 emulation function.

        * sys1.unx (zsysdep_local_name): put utsname structure on stack
        rather than making it static.

        * sysh.unx, sys1.unx (usysdep_initialize, getcwd): if we have
        neither getcwd nor getwd, fork /bin/pwd to get the current working
        directory.

        * system.h, uucico.c (main), uuxqt.c (main), uux.c (main), uucp.c
        (main), uuchk.c (main), sys1.unx (usysdep_initialize), sys6.unx
        (fsysdep_needs_cwd, zsysdep_add_cwd): because getting the current
        working directory can be expensive on Unix, since some
        implementation of getcwd fork a shell to execute pwd, only try to
        get the cwd if it is going to be needed by uux or uucp.

        * uucico.c (main), uuxqt.c (main), uux.c (main), uucp.c (main),
        uuchk.c (main), log.c (ulog): handle all possible signals raised
        by abort, namely SIGABRT, SIGILL and SIGIOT.  In ulog always call
        abort rather than raise (SIGABRT).

        * sys4.unx (usysdep_get_work_free): the qSwork_file information
        was freed up incorrectly if a file transfer failed.

        * sysh.unx, sys2.unx: Archaic Zilog System III computers use
        setret and longret rather than setjmp and longjmp, so I added a
        HAVE_SETRET configuration option.

        * prott.c (ftstart, ftsenddata): shifts of integers by more than
        15 are not portable.

        * prot.c (fsend_file, freceive_file, fploop, fgot_data): I ran
        into an old compiler which couldn't handle the calls to pffile, so
        I simplified them to use a variable.

        * port.c (fmodem_dial): cast result of alloca.

        * getopt.h, getopt.c: Jay Vassos-Libove: renamed getopt and
        related variables by macro defining them to gnu_*.  This avoids
        conflicts with system header files and system libraries.

Fri Feb  7 12:08:42 1992  Ian Lance Taylor  (ian@airs.com)

        * everything: added HAVE_STRING_H and HAVE_STRINGS_H.  Removed
        include of <string.h> in every source file and put it in uucp.h.
        Since I had to change everything anyhow, added 1992 to the
        copyright date.

        * uucico.c (fcall): Bob Denny: retry time not reached is not
        really an error, so just make a normal log entry for it.

Sun Feb  2 01:38:47 1992  Ian Lance Taylor  (ian@airs.com)

        * uucp.c (main): Get the file name for the destination of a local
        copy using zsysdep_real_file_name rather than zsysdep_in_dir,
        since the latter doesn't get the basename of the argument.

        * sys3.unx (fsysdep_get_status): Niels Baggesen: cast enum to int
        before comparison.

        * system.h, uucp.c (main), uux.c (main), sys6.unx (fsysdep_access,
        fsysdep_daemon_access): Niels Baggesen: check user access to file
        since programs are running setuid.  Previously uucp and uux
        permitted a file readable only by uucp to be transferred to
        another system by user request!

        * chat.c (fchat): Michael Nolan: portions of a chat string might
        be separated by more than just a single space if they are read
        from a V2 or BNU configuration file.

Fri Jan 31 19:51:57 1992  Ian Lance Taylor  (ian@airs.com)

        * protg.c: Chip Salzenberg: change default window size to 7.

        * sys3.unx (fsdo_unlock): Michael Nolan: cast result of alloca to
        (char *), not that it really matters.

        * log.c (ulog): Michael Nolan: if SIGABRT is not defined, just
        call abort.

Thu Jan 30 18:19:33 1992  Ian Lance Taylor  (ian@airs.com)

        * bnu.c (ubadd_perm): Michael Nolan: debugging check was done
        wrong for entry with LOGNAME but no MACHINE.

Wed Jan 29 13:28:59 1992  Ian Lance Taylor  (ian@airs.com)

        * uucico.c (zget_uucp_cmd): Patrick Smith: only wait a short time
        for the hangup string.

        * sys4.unx (iswork_cmp): Patrick Smith: fixed casts to not cast
        away const.

Tue Jan 28 11:06:34 1992  Ian Lance Taylor  (ian@airs.com)

        * sys1.unx, sys3.unx, tstuu.c: Jay Vassos-Libove: removed some
        declarations of system functions that conflict with system header
        files on BSD/386 alpha.

        * Makefile: Jeff Ross: make sure the uninstall target restores the
        original file owner and mode.

        * protg.c (fgsendcmd): the previous patch wasn't really correct.

Mon Jan 27 22:30:47 1992  Ian Lance Taylor  (ian@airs.com)

        * log.c (ustats): Marty Shannon: don't report a failed transfer
        under USE_BNU_LOGGING.

        * sys3.unx (zsysdep_real_file_name): Marty Shannon: a trailing '/'
        on the name means that it is a directory, even if the directory
        does not already exist.

        * uucico.c (fuucp): Marty Shannon: the -f flag indicating that
        directories should not be created was not being handled correctly.

        * uucico.c (fcall): Chip Salzenberg: set .Status correctly if
        wrong time to call.

        * protg.c (fgsendcmd): John Antypas: didn't handle null byte at
        end of command which was exactly a power of two in length
        correctly.

Tue Jan 21 14:37:10 1992  Ian Lance Taylor  (ian@airs.com)

        * Released version 1.02.

        * system.h, uucico.c (main), uux.c (main), uucp.c (main,
        zcone_system), sys1.unx (fsysdep_run): Chip Salzenberg: have uucp
        and uux start up uucico -s system rather than uucico -r1.

Mon Jan 20 11:45:38 1992  Ian Lance Taylor  (ian@airs.com)

        * sys1.unx (fsysdep_make_dirs): don't try to create a directory
        with no name.

        * version.c: change version number to 1.02.

        * uucico.8, uuxqt.8, uucp.1, uux.1: change version number to 1.02.

        * MANIFEST: removed texinfo.tex; it's twice the size of any other
        file, so I think it's just to large to distribute.

        * uucico.c (fcall, fdo_call): Marty Shannon: update the time in
        the .Status file if it's the wrong time to call, and upon
        receiving a call.

Sun Jan 19 13:29:23 1992  Ian Lance Taylor  (ian@airs.com)

        * protg.c (fgsendcmd, fgsenddata): Dave Platt: if the remote UUCP
        accepts packets larger than 64 bytes, assume it can handle
        differing packet sizes, so if we have a small amount of data to
        send, use a small packet.  Besides the two routines mentioned,
        also made minor changes to other routines to get the packet length
        out of the packet data rather than always assuming the same packet
        size.

        * conf.h, uucp.h: Matthew Lyle: some systems don't declare errno
        in <errno.h>, so I added HAVE_ERRNO_DECLARATION.

        * conf.h, uucp.h, util.c (bsearch): added HAVE_BSEARCH
        configuration parameter.

Sat Jan 18 17:45:28 1992  Ian Lance Taylor  (ian@airs.com)

        * tstuu.c (utransfer): Mike Park: don't sleep when the input
        buffer is full; it's too slow.

        * Makefile: when making a distribution,change the mode of separate
        copies of the configuration files Makefile, conf.h and sysh.unx.

        * uucico.c (faccept_call): Marty Shannon: update .Status file on
        incoming calls.

        * uucp.h, prot.h, uucico.c (fuucp), prot.c (fsend_file,
        fpsendfile_confirm, freceive_file, fprecfile_confirm, fxcmd,
        ustats_failed), file.c (fsent_file, usendfile_error,
        freceived_file, urecfile_error, frecfile_rewind, fmail_transfer):
        reworked calls to fsydep_did_work and sending of mail messages to
        be more sensible.  Now sends mail to requestor if request fails
        permanently and does not remove file if request fails only
        temporarily.

Thu Jan 16 11:33:08 1992  Ian Lance Taylor  (ian@airs.com)

        * protg.c (fgsendcmd, fgsenddata): zero out unused bytes in short
        packets.

        * prot.c (zgetcmd), protf.c (ffsendcmd), prott.c (ftsendcmd),
        prote.c (fesendcmd): Niels Baggesen: added some debugging
        messages.

        * protg.c (fgsendcmd): corrected misspelling in debugging message.

        * log.c (ustats): Niels Baggesen: add FAILED to end of xferstats
        line if appropriate.

        * uuxqt.c (uqdo_xqt_file): Niels Baggesen: was checking strcmp
        return value incorrectly, so messages to other systems were not
        being sent.

        * sys2.unx, tstuu.c: Mike Park: ioctl is sometimes declared
        varadic, so we can't declare it.

Wed Jan 15 02:03:43 1992  Ian Lance Taylor  (ian@airs.com)

        * sys1.unx: put \n at end of fsysdep_run error message.

        * sysh.unx, sys1.unx, sys2.unx, tstuu.c: Mike Park: on some
        systems <sys/time.h> includes <time.h> but <time.h> can only be
        included once; added HAVE_SYS_TIME_AND_TIME_H to sysh.unx.

        * tstuu.c: Mike Park: removed prototype for times since some
        systems don't have clock_t.

        * conf.h, sys2.unx, util.c: Mike Park: some systems don't have
        <limits.h>.  Every macro used from it already had a check to make
        sure it was defined anyhow.

        * tstuu.c (uprepare_test): Mike Park: sh on NeXT interprets a
        leading ~, so we have to quote the argument to system(3).
        Incredible.

        * conf.h, uucp.h: Mike Park: if HAVE_ALLOCA is 0 when compiling
        with gcc, don't define alloca as a macro.  This will let the NeXT
        define it in some header file.

        * sysh.unx, sys2.unx, sys5.unx, tstuu.c: Mike Park: handle
        HAVE_UNION_WAIT completely.  Assume that system(3) returns an int
        which should be put into the w_status field.  Define macros for
        union wait if they are not already defined.  Move all this stuff
        into sysh.unx rather than duplicating it in three different files.

        * conf.h, uucp.h, sysh.unx, config.c, bnu.c, v2.c, uucico.c,
        uuxqt.c, uux.c, uucp.c, uuchk.c, Makefile: set directory to look
        for configuration files in in Makefile rather than in sysh.unx.
        This forced a number of changes, as now all new style
        configuration files are looked up using NEWCONFIGLIB.  Old style
        configuration files are looked up using OLDCONFIGLIB.

Mon Jan 13 00:35:43 1992  Ian Lance Taylor  (ian@airs.com)

        * sys3.unx: David Nugent: don't declare chmod, since it may be
        prototyped to take an argument that is smaller than an int.

        * uucico.c (faccept_call): Chip Salzenberg: only declare sportinfo
        if it will be used (if HAVE_TAYLOR_CONFIG is true).

        * sys3.unx (isysdep_get_sequence): Chip Salzenberg: avoid use
        before set warning from gcc.

        * protf.c (ffprocess_data): Chip Salzenberg: avoid use before set
        warning from gcc.

        * sysh.unx, sys2.unx (fsserial_read, usysdep_pause): Chip
        Salzenberg: added HAVE_USLEEP configuration parameter for the AIX
        usleep routine.

        * uuchk.c, prtinf.c, config.c: Chip Salzenberg: strcmp is a macro
        on AIX, so avoid declaring it and undef it in config.c where we
        want to declare it because we want to take its address.

        * uucp.h, sys3.unx (fsysdep_get_status, fsysdep_set_status): Chip
        Salzenberg: handle out of range status codes in status files.

        * Makefile, sysh.unx: defined LIBDIR in the Makefile, rather than
        forcing the user to define it in two different places.

        * sys.unx, tstuu.c: Chip Salzenberg: can't declare execl, since it
        is varadic.

        * sys1.unx, sys2.unx, sys3.unx, sys5.unx, tstuu.c: David Nugent:
        can't declare open or fcntl, since they may use ... in header file
        prototype; added declaration for popen; added casts of first mkdir
        argument to char *.

        * sysh.unx, tstuu.c (uchild): Mike Park: added HAVE_WAITPID and
        HAVE_WAIT4 configuration parameters to allow the use of wait4 as
        found on the NeXT.

        * tstuu.c (uprepare_test): Mike Park: use IPUBLIC_DIRECTORY_MODE
        rather than S_IRWXU | S_IRWXG | S_IRWXO.

        * sysinf.c (tisystem): Mike Park: ulog was being passed the wrong
        number of arguments.

Sun Jan 12 14:32:47 1992  Ian Lance Taylor  (ian@airs.com)

        * Eliminated CONFIG, INSTALL and THANKS.  They are now included in
        uucp.texi.  Changed README and MANIFEST accordingly.  Added
        uucp.info* and texinfo.tex to MANIFEST.

        * Makefile, uucp.texi: renamed taylor.texi to uucp.texi.

        * uucico.c (fcall, fdo_call): John Antypas: pass in sportinfo
        structure for fdo_call to use for an unknown port.

        * log.c (ulog): allocate enough bytes to name file if
        HAVE_BNU_LOGGING is in use but zLogfile has no %s.

Sat Jan 11 12:11:56 1992  Ian Lance Taylor  (ian@airs.com)

        * Makefile: changed to correspond to GNU standards, according to
        standards.text of 24 Nov 91.

        * Makefile: Franc,ois Pinard: use $(INSTALL_PROGRAM) and
        $(INSTALL) rather than cp to install the programs.

        * time.c (ftime_now), sys1.unx (usysdep_localtime): John Antypas:
        use memcpy to get the result of localtime rather than relying on
        structure assignment.

        * sysh.unx, prtinf.c: Hannu Strang: changed definition of
        SYSDEP_STDIN_CMDS to pass structure instead of address of
        structure to avoid bug in AIX compiler which causes it to fail to
        recognize an address constant containing the -> operator.

Tue Jan  7 10:22:43 1992  Ian Lance Taylor  (ian@airs.com)

        * Released beta 1.02.

        * protg.c (fgcheck_errors): discount out of order packets in the
        total error count, and allow a negative error count to mean that
        any number of errors are accepted.

        * sysinf.c (tadd_proto_param): Niels Baggesen: allocate number of
        protocol parameters based on *pc, not sIhold.cproto_params.

Sat Jan  4 16:42:21 1992  Ian Lance Taylor  (ian@airs.com)

        * log.c (ulog): tweaked HAVE_V2_LOGGING slightly.

        * v2.c (uv2_read_systems): set chat script correctly.

        * uucp.h, sys3.unx: avoid redefining SEEK_SET if it appears in
        <unistd.h> but not <stdio.h>.

        * chat.c (fcsend): made fcsend into a static function.

        * uucp.h, uucico.c, uuxqt.c, uux.c, uucp.c, uuchk.c, version.c:
        changed abProgram and abVersion from const char [] to char []
        because the Microsoft compiler on SCO can't handle const char []
        arrays correctly.

        * uux.c (main): allocate enough space for log message.

        * sys1.unx (usysdep_localtime): to get the current time, we can't
        call usysdep_full_time if the latter uses times.

        * sys1.unx, sys3.unx: added a couple more extern definitions for
        SCO 3.2.2.

        * uucico.c (main): start uuxqt even if a call fails.

        * sysh.unx, system.h, uuxqt.c (uqdo_xqt_file), sys5.unx
        (fsysdep_xqt_check_file): Chip Salzenberg: added configuration
        option ALLOW_FILENAME_ARGUMENTS to permit arguments that look like
        filenames, to allow undoing the patch I just made.

Fri Jan  3 00:44:59 1992  Ian Lance Taylor  (ian@airs.com)

        * system.h, uuxqt.c (uqdo_xqt_file), sys5.unx
        (fsysdep_xqt_check_file): David J. Fiander: make sure that if an
        argument looks like a filename we are permitted to access it.

        * sys3.unx (fsdo_lock): remove temporary file if link fails in
        fsdo_lock.

Thu Jan  2 00:01:53 1992  Ian Lance Taylor  (ian@airs.com)

        * protg.c (fgstart, fgshutdown, fgprocess_data): count remote
        rejections separately from resent packets when counting errors.

Tue Dec 31 14:31:38 1991  Ian Lance Taylor  (ian@airs.com)

        * protg.c (fgstart): Franc,ois Pinard: forgot to initialize
        cGdelayed_packets.

        * prot.h, uucico.c, prote.c: added the 'e' protocol, creating the
        new file prote.c

        * prot.c (freceive_data), protf.c (fffile), prott.c (ftfile):
        changed pffile protocol entry point to pass number of bytes being
        sent; fixed bug in freceive_data which caused to ask for the wrong
        number of bytes when the buffer was empty.

Mon Dec 30 23:16:48 1991  Ian Lance Taylor  (ian@airs.com)

        * sys2.unx (fsserial_open): Chip Salzenberg: don't turn on IXON
        and IXOFF initially; after all, the initialization packets might
        contain an XOFF character.

Sun Dec 29 00:00:42 1991  Ian Lance Taylor  (ian@airs.com)

        * uucp.h, prot.c (fploop): John Theus: check for EOF before
        reading from file to work around bug in Tektronix library.

        * protg.c (fprocess_data): don't send RR packets when an error
        occurs; the other side will probably ignore them, and it may
        confuse some Telebit modems.

        * sys1.unx (usysdep_localtime): don't take the address of a cast
        value.

        * log.c (zldate_and_time): wasn't allocating enough buffer space.

Sat Dec 28 01:09:58 1991  Ian Lance Taylor  (ian@airs.com)

        * uuxqt.c (uqdo_xqt_file): forgot to initialize zmail.

        * uucp.h, time.c, copy.c, sys1.unx, sys2.unx, sys3.unx, sys4.unx,
        sys5.unx, config.c, log.c, uuxqt.c, uux.c, tstuu.c: added a bunch
        of externs to decrease the number of implicit function
        definitions.

        * system.h, sys1.unx (usysdep_localtime), log.c (zldate_and_time):
        Lele Gaifax: put the full year in the log file, using the format
        YYYY-MM-DD HH:MM:SS.HH (ending in hundredths of seconds).

        * config.c (uprocesscmds): Terry Gardner: allow a # to be quoted
        in a configuration file.  Also made uprocesscmds reentrant.

        * sysh.unx, sys2.unx (fsrun_chat), sys5.unx (fsysdep_execute),
        tstuu.c (uchild): Monty Solomon: added HAVE_UNION_WAIT
        configuration option to pass a variable of type union wait to the
        wait and waitpid system calls.

        * sysh.unx, sys1.unx (usysdep_initialize): John Theus: added
        HAVE_GETWD to use getwd instead of getcwd.

        * sysh.unx, sys1.unx (usysdep_full_time): added HAVE_FTIME
        configuration option.

        * tstuu.c (uchild): use TIMES_TICK from sysh.unx rather than
        CLK_TCK.

        * conf.h, uucp.h, util.c, getopt.c, tstuu.c: added HAVE_STRCHR and
        HAVE_INDEX to conf.h.

Fri Dec 27 01:00:41 1991  Ian Lance Taylor  (ian@airs.com)

        * uucico.c (fuucp): set fmasterdone correctly when running as a
        slave.

        * port.c (cpshow, upshow, fport_read, fport_write, fport_io):
        cleaned up debugging code by isolating out upshow and by making
        cpshow handle backslash.

        * tstuu.c (uprepare_test): create spool directories by hand, to
        make sure test 6 can be done and to test creating needed
        directories.

        * conf.h, uucp.h, bnu.c, v2.c, chat.c, protg.c, prott.c, sysinf.c,
        tcp.c, getopt.c, tstuu.c, util.c: added HAVE_MEMFNS and HAVE_BFNS
        to conf.h.  Changed memset calls to use bzero.

        * protg.c (fgcheck_errors, fgprocess_data): added protocol
        parameter ``errors'' to set maximum number of errors permitted.
        Also made fgprocess_data only reply once per batch of data.

Thu Dec 26 17:54:54 1991  Ian Lance Taylor  (ian@airs.com)

        * tcp.c (ftcp_dial, itcp_port_number): Monty Solomon: cast
        arguments to avoid prototype errors on NeXT.

Mon Dec 23 00:16:19 1991  Ian Lance Taylor  (ian@airs.com)

        * uucp.h, sysinf.c, uucico.c (main, flogin_prompt, faccept_call),
        uuchk.c (main): David Nugent: allow debugging level to be set for
        a specific system.

Sun Dec 22 15:51:10 1991  Ian Lance Taylor  (ian@airs.com)

        * conf.h, uucp.c, sysh.unx, tcp.c, sys1.unx, sys2.unx, sys3.unx,
        sys5.unx, sys6.unx, tstuu.c: Monty Solomon: added HAVE_UNISTD_H to
        conf.h for systems which don't have <unistd.h>.  Also added
        externs for all functions from <unistd.h>, which required adding
        definitions for pid_t, uid_t and off_t to sysh.unx.

        * config.c, prtinf.c, time.c, uuchk.c: added externs for
        strcasecmp or strncasecmp, to avoid implicit function definitions
        now that I took the prototypes out of uucp.h.

        * sys3.unx (fsysdep_get_status): Franc,ois Pinard: the code added
        to avoid scanf had a stupid bug.

        * uucp.h: Monty Solomon: removed prototypes for strcasecmp and
        strncasecmp from uucp.h, since they may be in string.h.

Sat Dec 21 16:04:58 1991  Ian Lance Taylor  (ian@airs.com)

        * uucp.h, uucico.c (ucatch), prot.c (fpsendfile_confirm,
        fprecfile_confirm, ustats_failed), file.c (fsent_file,
        freceived_file), log.c (ustats): Terry Gardner: record failed file
        transfers in the statistics file.

        * uucico.c: change protocol ordering to 't', 'g', 'f'.

        * uucico.c (faccept_call), tstuu.c (uprepare_test): John Theus:
        don't warn if the port file doesn't exist when the slave mode
        uucico looks up the port.

        * sys1.unx, sys5.unx: moved fsysdep_file_exists from sys5.unx to
        sys1.unx so that uucico can call it.

        * uux.c: Fran,cois Pinard: remove parentheses from ZSHELLSEPS so
        that they may be used to quote arguments as documented.  This
        means that may not be used to start subshell, but that is no great
        loss.

        * uux.c (main): use ulog to report illegal grade error message.

        * sys1.unx (fsysdep_run): use the real program name from abProgram
        in the error messages in fsysdep_run.

Thu Dec 19 19:02:28 1991  Ian Lance Taylor  (ian@airs.com)

        * uucico.c (fdo_call, faccept_call): Terry Gardner: put the length
        of the conversation in the ``Call complete'' log file message.

        * uux.c: added space and tab to ZSHELLSEPS, because otherwise the
        command was parsed to include whitespace.

        * protg.c, protf.c: Oleg Tabarovsky: added statistical logging
        messages to the 'g' and 'f' protocols.  These go to the main log
        file right now, but I'm not sure if that's appropriate.

        * sys2.unx (fsserial_set): don't change terminal settings if we
        don't have to.

        * port.c (fport_io): add complete diagnostics for fport_io so we
        can see every byte that goes in or out.

        * uucico.c (fuucp): don't give user name in errors produced by
        getting the next command.

        * uuxqt.c (main): don't process execute files for unknown systems.
        This is not unreasonable, I hope, and it avoids errors caused by
        an uninitialized sUnknown structure.

        * sys4.unx (fsysdep_get_work_init): sort the previously found
        files all together so we can correctly check new files using
        bsearch.

        * protf.c (pfprocess, pfprocess_data, pfwait): Franc,ois Pinard:
        don't kill 'f' protocol because of an illegal byte.  Also slightly
        optimized the protocol to wait for up to seven characters at a
        time rather than just one.

Wed Dec 18 00:12:42 1991  Ian Lance Taylor  (ian@airs.com)

        * sysh.unx, sys2.unx, tstuu.c: Terry Gardner: added
        USE_FOR_UNBLOCKED configuration parameter to support systems that
        don't permit O_NONBLOCK and O_NDELAY to both be set.

        * tstuu.c (uchild): give the uucico processes a chance to die on
        their own rather than killing them immediately.

        * uuxqt.c (main, uqdo_xqt_file): David Nugent: keep rescanning the
        list of execute files until nothing can be done.  Also, don't
        remove the execute file if we get some sort of internal error.

        * sys4.unx (fsysdep_get_work, usysdep_get_work_free): David
        Nugent: after we've processed all the work files we found
        initially, rescan the work directory to pick up any that may have
        come in in the meantime.  Also, reset iSwork_file to 0 in
        usysdep_get_work_free so that we can handle more than one system.

        * tstuu.c, uucico.c (main, fwait_for_calls, flogin_prompt): added
        -l option to uucico to prompt for the login name and password once
        and then exit.

Tue Dec 17 00:24:41 1991  Ian Lance Taylor  (ian@airs.com)

        * uucp.h, uucico.c, uuxqt.c, uux.c, uucp.c, config.c
        (uread_config), log.c (ulog): eliminated ulog_program and added
        abProgram and ulog_to_file.  Made log messages output to stderr
        more Unix like.

        * log.c (ulog): use a fixed number of fields in a log file message
        by replacing a missing system or user with '-'.

        * port.h, chat.c (renamed fchat_send to fcsend), bnu.c
        (fbnu_read_dialer_info), prtinf.c (tpcomplete), sys2.unx
        (fsysdep_modem_close), uuchk.c (ukshow_dialer): T. William Wells:
        change the modem complete and abort strings into chat scripts.

        * sys2.unx (fsserial_open): on BSD start in RAW mode to avoid
        dropping characters when we switch over.  I originally thought
        being able to use XON/XOFF was worth the risk; I no longer think
        so.

        * tstuu.c (uprepare_test): have shell script sleep before printing
        the login name to make sure the second system has finished
        flushing its input buffer.

        * protg.c (fginit_sendbuffers), prott.c (ftsendcmd): David Nugent:
        avoid sending confidential information by zeroing out memory
        buffers before using them.

        * sysinf.c (tirequest, titransfer), prtinf.c (tpseven_bit,
        tpreliable, tpdtr_toggle): Marc Unangst: several functions did not
        accept true and false as boolean strings, contradicting the
        documentation.

        * uucp.h, system.h, sysh.unx, sys1.unx (usysdep_full_time), file.c
        (fstore_sendfile, fsent_file, fstore_recfile, freceived_file),
        log.c (ustats): generate statistics in microseconds instead of
        seconds for more accurate time keeping.

        * sys2.unx (fsserial_open): David Nugent: flush pending input
        when a serial port is opened.  This will clear out a
        NO\sCARRIER string left by a previous dropped connection.

Mon Dec 16 11:26:17 1991  Ian Lance Taylor  (ian@airs.com)

        * uucico.c (main), uuxqt.c (main), tstuu.c (main, uchild): David
        Nugent: ignore SIGHUP in uucico and uuxqt, so that they are
        unaffected by the parent shell closing down and by the remote
        terminal dropping the connection.

        * bnu.c (ubnu_read_sysfiles, ubnu_read_systems, fbnu_find_port,
        fbnu_read_dialer_info): Mike Bernson: ignore lines that begin with
        whitespace, fix compilation error.      

Sat Dec 14 20:59:10 1991  Ian Lance Taylor  (ian@airs.com)

        * sys2.unx (fsserial_open): don't turn on ISTRIP initially.

        * uucp.h, sysinf.c, chat.c (icexpect), uuchk.c (ukshow_chat):
        added chat-seven-bit command to allow control over whether
        parity bits are stripped out of chat scripts.

        * uucp.h, port.h, chat.c (fchat, fcprogram),
        config.c (tprocess_one_cmd), prtinf.c,
        sysinf.c (tichat, tprocess_chat_cmd),
        bnu.c (fbnu_read_dialer_info), port.c (fpdo_dial),
        uucico.c (fdo_call, faccept_call) uuchk.c (ukshow_chat):
        changed processing of chat commands to go through
        tprocess_chat_cmd, avoiding repetition.  All chat script
        information is now held in an schat_info structure.
        Eliminated the fchat_program function, renaming it fcprogram
        and making it static to chat.c (it is now called via fchat).
        Added CMDTABTYPE_PREFIX.  Added INIT_CHAT macro to initialize
        chat script information.  Added TTYPE_CMDTABTYPE and
        CARGS_CMDTABTYPE to eliminate hex constants in
        tprocess_one_cmd.

        * sys5.unx (zsysdep_get_xqt): Oleg Tabarovsky: don't stop
        processing files just because opendir failed on one; it could just
        be because we don't have read permission.

Fri Dec 13 17:43:52 1991  Ian Lance Taylor  (ian@airs.com)

        * config.c (uprocesscmds): don't continually allocate and free the
        array of arguments.

Thu Dec 12 12:46:01 1991  Ian Lance Taylor  (ian@airs.com)

        * prot.c (fgetcmd): Franc,ois Pinard: don't bother to give an
        error if the final HY doesn't come in; apparently the MtXinu UUCP
        doesn't send it.

        * chat.c (icexpect, fchat_send): Franc,ois Pinard: add some chat
        script debugging messages.

        * log.c (ulog): David Nugent: move ERROR: from the start of the
        line to after the date and time; this makes it easier to use awk
        on log files.

        * sys3.unx (fsdo_lock), sys1.unx (usysdep_initialize): do locking
        using link rather than O_CREAT | O_EXCL to avoid race conditions
        and to safely run as the superuser.

        * sys3.unx (fsysdep_move_file): fcopyfile now creates the
        destination file with IPRIVATE_MODE, so we don't need to chmod to
        it.

        * sys1.unx (usysdep_initialize, fsysdep_other_config): set the
        GID as well as the UID, in case anybody wants to run this as a
        setgid package.

Wed Dec 11 10:03:22 1991  Ian Lance Taylor  (ian@airs.com)

        * conf.h, uucp.h, util.c (strtol): Mark Powell: added my own
        version of strtol to util.c, for systems which lack it.

        * protg.c (fgstart, fgexchange_init): if we start resending
        packets during initialization, don't forget which packets we have
        already seen; otherwise the other side may assume we've already
        seen them while we're looking for them.

Tue Dec 10 15:42:41 1991  Ian Lance Taylor  (ian@airs.com)

        * conf.h, sysh.unx, log.c (ulog, ustats), tstuu.c (uprepare_test):
        Arne Ludwig: merged in Arne Ludwig's patches to support V2 and BNU
        style logging, with some minor additions and changes.

        * sys1.unx, sys3.unx, sys5.unx, uux.c, uucp.c, uucico.c, copy.c,
        uucp.h, system.h: create directories when necessary rather than
        assuming that they exist.  Added fmkdirs argument to esysdep_fopen
        and fcopy_file, changing all calls.  Added fpublic argument to
        fsysdep_make_dirs, changing all calls.  Moved fsysdep_make_dirs
        and fsdirectory_exists from sys3.unx to sys1.unx.  Added checks
        for ENOENT in several places in sys3.unx and sys5.unx.

        * log.c, port.c (fport_open), sys2.unx (fsserial_open): added
        ulog_device routine to record device name.  This is currently only
        used for the BNU statistics file, but more uses might arise later.

        * file.c, log.c, uucp.h: moved statistics file routines from
        file.c to log.c in preparation for supporting BNU log file
        routines.

Mon Dec  9 12:00:52 1991  Ian Lance Taylor  (ian@airs.com)

        * bnu.c (ubnu_read_systems): Arne Ludwig: the device entry for a
        system can be followed by a comma and a list of protocols.

        * sysh.unx, sys3.unx (fsdo_lock): Richard Todd: add
        HAVE_V2_LOCKFILES, in which the process ID is written out in
        binary.

        * uuxqt.c (uqdo_xqt_file): Richard Todd: the requestor address is
        relative to the requesting system.

        * config.c (uprocesscmds, umulti_pushback): Richard Todd: each
        line pushed back because of "#" is local to a particular
        smulti_file structure.

        * prtinf.c (asPdialer_cmds): Richard Todd: exit the current dialer
        if the special command "#" is seen.  A similar thing should be put
        in for ports, but it's marginally more complex.

        * config.c (uprocesscmds): Richard Todd: don't warn if the special
        "#" command is unrecognized.

Sat Dec  7 13:05:40 1991  Ian Lance Taylor  (ian@airs.com)

        * config.c (uprocesscmds): Franc,ois Pinard: don't limit the
        number of arguments to a command!

        * chat.c (fchat): handle a chat script which consists only of a
        single string.

Fri Dec  6 16:11:29 1991  Ian Lance Taylor  (ian@airs.com)

        * sys5.unx (fsysdep_execute): David J. Fiander: if execve fails
        with ENOEXEC, try using /bin/sh with a quoted argument.

        * uux.c (main): split arguments the way /bin/sh does.  If any
        shell metacharacters appears, request uuxqt to execute the command
        using /bin/sh.

        * tstuu.c (uprepare_test): allow the uux to test to send a failure
        message.

        * uuxqt.c (uqdo_xqt_file): don't send mail on successful execution
        unless specifically requested; pay attention to the 'n' line
        which requests mail on success; ignore the 'Z' line because it
        now specifies the default action.

        * sys1.unx (usysdep_initialize), sys6.unx (zsysdep_add_cwd):
        Franc,ois Pinard: getcwd may legitimately fail, so only give an
        error if we really need the result.

        * chat.c (ccescape): Franc,ois Pinard: ccescape should never
        return a negative number, since the callers don't know how to deal
        with that.

Mon Dec  2 16:26:16 1991  Ian Lance Taylor  (ian@airs.com)

        * bnu.c (ubnu_read_systems): Dave Buck: time strings with grades
        were parsed in an endless loop!

        * sys3.unx (fsdo_lock, fsdo_unlock): the alloca when using LOCKDIR
        was one byte too small.

        * config.c (tprocess_one_cmd): pass 10 to strtol rather than 0 to
        avoid surprises if a leading zero is used.

        * prtinf.c (tpproto_param, tpdialer_proto_param): Niels Baggesen:
        the ``protocol-parameter'' command didn't work for ports or
        dialers.

Sun Dec  1 09:46:12 1991  Ian Lance Taylor  (ian@airs.com)

        * tstuu.c: don't use the fd_set typedef at all.

        * tstuu.c (uprepare_test): don't read V2 or BNU configuration
        files while testing.

        * bnu.c, v2.c, config.c (uread_config): David Nugent: even if the
        code was compiled with HAVE_TAYLOR_CONFIG, read the V2 and BNU
        configuration files if the code was compiled to support them.

        * uuchk.c (fkshow_port): Bob Izenberg: report dialer/token pairs
        correctly.

Sat Nov 30 17:40:00 1991  Ian Lance Taylor  (ian@airs.com)

        * tstuu.c: Bob Izenberg: copied over conditional definitions of
        EAGAIN and EWOULDBLOCK from sys2.unx.

        * bnu.c (fbnu_read_dialer_info): Niels Baggesen: accept dialers
        with no substitutions.

        * bnu.c (ubnu_read_systems, ubadd_perm): Niels Baggesen: don't
        free up zline in ubadd_perm; in fact, changed the calling sequence
        to not even pass zline in at all.

        * bnu.c (ubadd_perm): Niels Baggesen: didn't handle multiple
        MACHINE= and multiple LOGNAME= values in a single Permissions
        line, because it was clobbering the machine name while processing
        the first logname.

        * bnu.c: Made zread and zwrite elements of sperm structure const
        char * to avoid warning.

        * copy.c, sys1.unx, sys2.unx, sys3.unx, sys5.unx, tstuu.c: Niels
        Baggesen: don't multiply include <unistd.h>.  Eventually there
        should be a macro controlling whether it gets included at all, for
        non-POSIX systems.

        * sys3.unx (fsysdep_get_status, isysdep_get_sequence): Marty
        Shannon: accept a truncated status file.  I also eliminated scanf
        calls in sys3.unx, since that was the only place it was called;
        this was to make the executables smaller for systems which cared.

        * bnu.c (ubnu_read_sysfiles): Marty Shannon: accept comment
        characters in Sysfiles.

        * sysh.unx, sys3.unx: Marty Shannon: added HAVE_RENAME, put a fake
        rename system call in sys3.unx.

        * prtinf.c (ffind_port): Marty Shannon: failed to handle multiple
        ports in the port file since I forgot to reset my pointer
        variable.

        * bnu.c (ubnu_read_systems): Marty Shannon: don't initialize the
        auto array abpubdir, since old cc didn't permit initialization of
        auto aggregates.

Mon Nov 25 20:56:39 1991  Ian Lance Taylor  (ian@airs.com)

        * tstuu.c: Bob Denny: add definitions for FD_SET, FD_ZERO and
        FD_ISSET.

        * config.c: Bob Denny: add explicit externs for strcmp and
        strcasecmp.

        * sys2.unx: the fread_blocking and fwrite_blocking fields were
        not getting initialized correctly in the TCP support routines.

        * sysh.unx, sys2.unx, sys5.unx, tstuu.c: Marty Shannon: added
        configuration option HAVE_SYSWAIT_H.

        * bnu.c (fbnu_find_port, fbnu_read_dialer_info), v2.c
        (fv2_find_port): Marty Shannon: the ireliable field of ports
        and dialers was not getting initialized.

Sun Nov 24 15:06:37 1991  Ian Lance Taylor  (ian@airs.com)

        * tcp.c (itcp_port_number): Michael Haberler: wasn't calling
        htons if passed a numeric string.

Sat Nov 23 13:43:52 1991  Ian Lance Taylor  (ian@airs.com)
