------- ------- ------------------------------------------------------

6/15/98 5.26.1  Dean Sauder  noted C-preprocessor lines in

                configure must start in column 0.

5/18/98 5.26.0  Kevin Schleicher  noted xkibitz leaves xterms

                if first xterm is HUP'd.  Kevin also noticed a resource leak

                in dislocate.  Both problems fixed.

                Robbie Gilbert  noted expect_devtty was logging

                devtty (twice) to stdout.  Fixed.

                Added support inttypes.h, required on Solaris 5.6 for termios.h

                Kristina   noted that tip failed when

                spawned from a cgi script (BSDI BSD/OS 3.1 i386) because tip

                didn't see a definition for SHELL and HOME.  They need to be

                set.  (Doesn't have to be anything useful; the empty string is

                fine!)  Solution: documented this in Expect man page.

                Zachariah Baum  noted that config.sub

                didn't grok Intel 686.  Found a newer version that did in

                autoconf-2.11.

                POTENTIAL INCOMPATIBILITY: Changed interact so that it observes

                parity while matching.  It used to ignore parity.  This impacts

                people who use interact to connect through to a real serial

                device that generates parity.  If matches don't work, use the

                exp_parity command.  (This fix should have been made years ago,

                when the exp_parity command was added.  It is now absolutely

                necessary now that people are doing matching with 8 bits.)

                After the second occurrence of a system admin who broke grantpt

                by removing setuid from the relevant system util, I added an

                explicit test and explanation.

                Disabled history in xkibitz.  There seems to be some new

                incestuous relationship between history and unknown now so that

                redefining unknown leaves Tcl calling history but without

                knowing what it is because it's never been defined (as it would

                be by the traditional unknown).

                Fixed quoting bug in passwd.cgi example.

9/28/97 5.25.0  Switched back to hand-generating pkgIndex.tcl file after too

                many complaints about problems running pkg_mkIndex.

8/12/97 5.24.1  Chris Schanzle  pointed out that

                install fails on a virgin file system because install_shared_

                lib depends on a directory that hasn't yet been created.

                Larry Virden gave corrections to URLs in README.

8/21/97 5.24.0  Bo Johansson  noted TclWordEnd

                had changed and provided fix.  This caused crash in expect.

8/18/97 5.23.0  This version supports Tcl 8.0 and continues support for 7.6.

                Refs to Tcl_Files dropped.  inter_return and close became

                obj cmds.  Rewrote notifier (again) to accomodate new notifier

                model.  Lots of other miscellaneous tweaks.  Also see debugger

                HISTORY file.

                Finally removed long-deprecated commands "continue -expect",

                "send_spawn", and "getpid" and their exp_ versions.

                Harold Brauer  reported problems

                with an old SCO system (i386-unknown-sco3.2v5.0) that turned

                out to be due to a typo in the configure script.

                Jimmy Aitken supplied mods to config.guess for brand new and

                very old Pyramid systems.

                Buz Owen noted memory leak in use of expect_background (with

                no args).

                Jonathon Kamens noted provided patch for pty_termios.c for

                modern Sequent (which ptmx).

                Jonathon Kamens noted that TCL defined RANLIB for shared lib

                (if --enabled-shared) which isn't appropriate when Expect tries

                to build both shared and unshared libs.

                Jonathon Kamens noted that shared lib config didn't work on

                SunOS.  I had used Tcl's SHLIB_SUFFIX instead of its

                SHARED_LIB_SUFFIX.

                Qingyi Liao  encountered core dump when

                exp_bg -i $exp_spawn_any was retracted.  Bug in ecmd_remove_fd.

                Fixed a bunch of bugs in example/gethostbyaddr.

                Josef Sachs noted that stty cannot be caught when no /dev/tty.

                It calls exit instead of returning an error.

                Gordon Chaffee  patched

                Exp_WaitCmd - it was zeroing pid element instead of wait.

                Bob Manson  provided fix for HP on which it

                was possible for timer to be mistakenly deleted in

                exp_get_next_event while processing a pty open event.

                Jeff Slonaker  noted that exp_poll.c

                had wrong signature and poll had arguments out of order!  That

                would suggest that no one has ever used exp_poll.c before...

        5.22.1  Larry Virden noted that TCL_BUILD_LIB_SPEC can't be used if

                build directory has been removed.  Added check to configure.

                Worked more on package command.  Buz Owen pointed out that my

                code wouldn't support redefinition of TCL_LIBRARY.  Bumped up

                minor version to avoid package loading mishaps.

                Nigel Standing  noted lack of C-u binding in

                tkpasswd - must be due to change in tk4.2.

                Forced env(SHELL) to be defined inside kibitz for when using

                with CGI.

                Charles Packer  noted that CRAY-YMP

                needed sys/types.h in exp_console.c

                Extra / when developing defn of TCL_LIBRARY.  Shouldn't

                actually cause any problems though.

2/3/97  5.22.0  Fixed package support - again.  Sigh.

                David Pasirstein  noted that RedHat

                Linux 2nd passwd prompt requires slightly different pattern -

                modified mkpasswd and tkpasswd.

                Toshiaki Nomura  provided patch to

                config.guess for Fujitsu DS/90.

                Roger Brooks  noted C lib passed

                argv[0] instead of file to first arg of execvp.

                Cary D. Renzema  noted that a simple puts -nnl

                might never appear - Expect closes all of its fds before Tcl

                gets a chance to flush.  Stdout is the obvious problem since

                Expect thinks it can cavalierly close that too.  Hmm.

                At request of Tom Tromey, solved possible missing tclRegexp.h

                problem by having Expect install it.  Cleaned up TCLHDIR and

                TCL_LIBRARY hackery in Makefile.

12/27/96 5.21.7 Nelson Beebe noted unset is not portable in /bin/sh.  Removed

                and converted everything to understand CONFIG_SHELL.

                Modified cryptdir to strip out shell metachars from filenames.

12/10/96 5.21.6 Michael Schumacher noted that some systems cannot build

                unshared libs from shared objects.  Chose to go with BLT's

                approach of building shared objs in separate shared directory.

                Buz Owen  noted that "package require Expect"

                didn't work because it looked for Expect lib in the wrong

                place (well, the "documented" place).  The problem is that Tcl

                insists libraries should be in the same directory as the

                pkgIndex.tcl file while the natural thing to do would be to

                split them up and put the .tcl file in the arch-indepent

                app-specific scripts dir and the lib in the arch-dependent

                common dir.  Sigh.  If this is ever fixed/changed, the

                instructions in the Makefile should be fixed.

                 noted that expect library name

                exceed filename max on some systems - like his old SCO.

12/4/96 5.21.5  Michael Schumacher noted new configure wasn't passing on Tcl's

                shared lib cflags.

10/26/96 5.21.4 Achyutram Bhamidipaty  ran into bugs in Expect's

                file event handler which prevented expectk from entering

                implied event loop.  Also found one memory problem - thanks

                to CenterLine.

                Tom Tromey fixed handling of --enable-shared when overriding

                Tcl's value et al.  Tom also added missing "else true" to

                Makefile: "In a Makefile, you have to always supply an "else"

                clause for an "if", to work around a bug in certain versions of

                sh.  In some versions of sh, an "if" whose test fails will

                return the status of the test if there is no "else" clause --

                causing spurious make failures."  See ChangeLog.

10/18/96 5.21.3 Example directory was missing several examples.

10/17/96 5.21.2 Debugger section of configure file corrupted.

10/10/96 5.21.1 Oops, distribution unpacked into wrong version.

                Tom Tromey provided patch for stty to understand OSF 4.0.

9/28/96 5.21.0  Official Expect release for Tcl 7.5.

                Junio Hamano  provided fixes for aclocal

                for with_tcl/tkconfig.

                Roger Billau  noted that C library

                didn't work on Solaris 2.5.  Turns out Solaris requires fflush

                be called between input and output operations on FILE pointers.

                Lots of Cygnus mods - see ChangeLog.

                Sid Cowles  and Hans Riethmann

                 noted relative path specs of tcl-includes

                (and others) caused debugger config to fail since it is at a

                different directory level.

                Al Snow  noted -C failed due to typo.

8/17/96 5.20b18 Andrew Rakowski  noted no defn of

                LIB_RUNTIME_DIR, a creation of Tcl7.5p1.

                Tom Tromey added -v to Expect and -version to Expectk.

                Ben Boule  noted that Interactive (IUNIX)

                requires 9 char max length after -l.  Looks like squeezing out

                the "." is sufficient.  He also noted that IUNIX needs -Xp in

                LIBS to find strftime.  This test should really be done by Tcl.

8/12/96 5.20b17 Glen Biagioni  noted interact -re "A(xx)"

                failed to match.  Problem turned out to be that Tcl 7.5 changed

                a constant which in the regexp code, which Expect didn't see

                because it provides its own defn for interact.  Alas, the one

                thing Expect reuses from Tcl was where the change was.  This

                should really be fixed so Expect doesn't rely on Expect in this

                way, but there's no point in putting in a lot of work on regexp

                when we're anticipating a new one soon anyway.

                Bjorn S. Nilsson  noted fixcat hangs.

                Turned out that new Tcl (7.5p1) now waits for all children to

                disappear.  But Expect still had a handle to a child.  I added

                an exit handler to close the connections before Tcl's exit

                handler.

                Tom Tromey provided patch to support augmenting CFLAGS on

                Makefile invocation.

                Gary Merinstein  noted that configure failed

                on his linux unless it had --enabled-shared.  Not quite sure

                about how this can be, but the flag wasn't being passed to the

                debugger's configure, so I've fixed that and hopefully this

                will cure the original prob.

                Added initial announcement of full version at beginning of

                configure.  This should ease my pain in responding to people

                sending me config output without including version numbers.

                Tom Tromey noted expect_cf.h was machine dependent.  Fixed

                expect_comm.h so that it no longer required expect_cf.h (which

                should be renamed to indicate it is no longer public).

                Bart Robinson  provides mods to support

                openpty() in FreeBSD/NetBSD.  Without openpty, Expect doesn't

                see the full pty namespace (ptyX[0-v]).

7/15/96 5.20b16 Nathan Estey  noted that Makefile failed

                on SunOS when shared libs were enabled due to incomplete dot

                stripping in lib prefix.

7/6/96  5.20b15 Malcolm Tredinnick  noted that shared lib

                has to be installed before building expect.  Also noted that

                ldconfig should be run on Linux 2.0 systems and maybe others.

6/25/96 5.20b14 Tim Mooney provided fixes to obey --includedir and similar

                configure conventions.

6/25/96 5.20b13 A bug when installing Expect using new _installed targets.

6/24/96 5.20b12 Numerous complaints from Solaris users about shared libraries.

                Unfortunately, no one is giving me configure-ready fixes so

                (and Tk's configure seems to have bugs as well) so fixing

                these is like throwing darts.

                Stan Brown  noted noidle example broke when

                fed "-".

                Gordon Irlam  noted typo in install-sh.

                David Sheinberg  noted no

                args test for spawn -open/leaveopen.

                Misc patches from Tim Mooney to pacify much of gcc -wall.

                Kayvan Sylvan insists Linux stty reads from stdin so added

                hardcoding to configure.in for that.  In xkibitz, Linux stty

                -raw didn't disable all post-processing.  How odd that it is

                not a problem in interact.  In the meantime, added extra stty

                to xkibitz to do what was missed.

5/30/96 5.20b11 Kayvan Sylvan  noted quoting bug in

                autoexpect.

5/22/96 5.20.b10 Patches from Larry Virden in Makefile.in and exp_int.h

5/20/96 5.20.b9 Too many substitutions in configure caused sed failures on

                DEC (limit 99) and HP (100).  Commented out definitions

                that weren't absolutely critical.  Hopefully, this gets us

                under the limit but can't be sure since there's no easy way

                of knowing.

                Numerous mods from Mark Diekhans to support clist-style ptys

                on SCO OpenServer.  (He says SVR4 ptys are broken on that

                platform.)

                Simon J. Gerraty  says that write() returns

                spec so of course we have no idea what's going on.  So I added

                code to try and recover from (or at least warn of) this.

                Tom Tromey unified decls of errno to #includes.

5/13/96 5.20b8  Tim Mooney  pointed out

                backwards stty test - this would have corrupted every platform!

                He also pointed out that alpha-dec-osf3.2  (3.2c) complained

                too many args to sed.  Someone earlier said similarly about

                HPUX 10, but I assumed it was the quotes in the weird stty

                flag I was passing, so that "fix" wasn't.  GNU sed has no

                problem, but obviously this is not sufficient for many people.

5/10/96 5.20b7  Renamed/numbered versions so that it's easier for others to

                track.

                Upgraded to autoconf 2.10.

                Matthias Kurz  noted Makefile problems

                with final Tcl7.5.

                Blair Zajac  noted configure mishandled

                stty defaults on HP and shared lib must be installed executable

                on HP.

                autoconf insists on adding -O to CFLAGS when using gcc.  Ack!

3/23/96 5.20b1  Beta release 1 of Expect for Tcl 7.5.

                Michael Hunter  provided misc mods for QNX.

                Various people reported problems with IRIX.  Removing from the

                stty list fixed the problem.  Similar problem with Solaris.

                Added explicit close to autoexpect.  Added a mechanism for

                enabling conservative mode after script is generated.

                Hal Schechner  pointed out passwd.cgi must

                meet passwd's requirement that it not be run by an unrelated

                user.  Easy enough - just do an su first.

3/26/96 5.20a5  Alpha release 5 of Expect for Tcl 7.5b3.

                Added example passwd.{html,cgi} to change a password.

                Many fixes from Stephen Williams 

                and Jonathon Kamens for Makefile and configure.

3/22/96 5.20a4  Alpha release 4 of Expect for Tcl 7.5b3.

                Added version number to lib directories (POTENTIAL

                INCOMPATIBILITY).

                Revised gethostbyaddr example - evidentally hadn't worked for

                some time!

                Jan Nijtmans  provided pkgIndex.tcl.in.

                Renamed Exp_Init to Expect_Init to support package cmd.

                Provided #define so that Exp_Init will continue to work.

                Revised exit handling so that it works if Expect is dynamically

                loaded.

                aclocal.m4 Patches from Tom Tromey.

3/15/96 5.20a3  Alpha release 3 of Expect for Tcl 7.5b3.

                Edward Haletky  noted that Machten required

                inclusion of types.h in exp_tty_in.h.

                Added various patches from Rob Savoye.  One incompatibility

                is that the static lib now ends with the version number.

                Added support for TCL_SHLIB_{LD_LIBS,VERSION} in Tcl b3.

                Jonathan Karges  found that clib

                was timing out immediately on -1.

3/6/96  5.20a2  Alpha release 2 of Expect for Tcl 7.5b2.

                Leland Joseph  noted

                expect-tests.exp exceeds the 14 character filename length.

                Added config.{sub,guess} to support AC_CANONICAL_....

                Rewrote much of aclocal, configure.in, and Makefile.in

                to handle Tcl/Tk config.sh files and shared/dl support.

                Simplified varargs/stdarg mess for Expect's C library.

                Threw away closetcl junk.  No longer required because

                Tcl finally started doing close-on-exec.

                Incorporated various fixes from Tom Tromey at Cygnus.

                See ChangeLog for details.

                Added require/provide support.

                Rejiggered event handling to support new Tcl_File interface.

                Removed libexpectk.  Because event loop was moved into Tcl, it

                is no longer necessary for it to be different than libexpect.

                Removed all support for earlier versions of Tcl and Tk.

                Numerous misc patches from Paul Eggert 

                most to support Tcl 7.5.

                Arnold Robbins supplied yet another patch to fix earlier

                problem noted by Hume Smith.

                David Engel  reported problem with Linux dumping

                core.  CenterLine, of course, immediately found the problem -

                uninit'd lowercase buffer.

                Peter Haggerty  noted that his Next

                died in cron.  It seems that Next doesn't support O_NOCTTY

                (even though the man pages says it does) and so during pty

                testing, control terminal would get allocated and then kill

                the process (by generating a HUP) when deallocated.  Avoid

                by ignoring HUP when doing pty testing on such machines.

1/3/96  5.19.0  Fixed bug that made expect report wrong string when using

                a terminating anchor in a positive-length glob match,

                reported by Graham L. Randall .

                Added rlogin-display to included examples.  rlogin-display

                automatically propagates your $DISPLAY when you rlogin.

                Hume Smith  noted problem

                with day of the week calc at year end/start.  Arnold Robbins

                supplied fixes.

                Jonathan Kamens provided fix to make sync byte reads

                recover from EINTR.

                Henry Spencer noted errant line of spaces in Makefile.

10/21/95 5.18.1 Began adding support for tcl7.5a1/tk4.1a1.  (not finished!!)

                - Make aclocal understand new Tcl/Tk directory layout

                  for finding tclInt.h and private libraries.

                - Added support for Tcl_AsyncReady.

                Paul Townsend  noted that distclean did

                not remove some config cruft.  Also recommended unsetting

                M*FLAGS that cause make called from configure to fail.

                Various fixes from Cygnus.  See Changelog.

                Deleted "-" before rm in loop in deinstall in Makefile as per

                Doug Claar .  Doug also found prob

                involving recent STTY fix.  Symptom was that pty wasn't

                correctly inited in cgi scripts on HPs - and Cray pty support

                blew up entirely.

                Added exp_ prefix to tests so that they can be run with other

                extensions.

                Seth Ornstein  noted bug in the

                way rftp detected symlinks.

                Upgraded to autoconf 2.4.  This fixes a bug in AC_PROC_CPP

                which blew up when CPP was defined in the environment.  Noted

                by John Pfuntner.

                Jonathan Kamens noted that library didn't check return pipe()

                return value.

                Added vrfy example.

                Przemek Klosowski  Irix 6.0 fails

                to use ptys that have been used by someone else.  SGI admitted

                this is a bug and the solution is to upgrade to 6.1.

                Yoad Grinberg noted "expect -timeout" mistakenly ate next arg

                as pattern.

8/24/95 5.18.0  Wayne Christopher noted that the way exp_eval_with_one_arg

                modifies the original argv makes the ICEM Tcl compiler unhappy

                so I rewrote it to avoid that.

                Ian Zimmerman  found that a braced arg list of

                a single pattern beginning with a \n caused expect to reeval

                for multiple args twice.  I added a -nobrace flag that expect

                and/interact can use internally to prevent this.

                Florian La Roche  noted a few

                glitches in the way -ltcl was searched for in aclocal.

                Joachim Posegga  noted lack of Tcl internal

                includes should be an error during configure.

8/10/95 5.17.8  Martin Wunderli  found missing

                quote in config.

                Danny Faught noted problems in Makefile when passing STTY defn

                with quotes.  Created another a STTY-less CPPFLAGS for cases

                where additional reexpansion occurs.

                Danny Faught noted bug in error handling for checking

                permission problem with /tmp.

8/1/95  5.17.7  Todd Rimmer  noted that HP 10 with

                optional streams package has both PTYM and PTMX which conflict

                in pty_termios.

                Rainer Wilcke provides fixes: scripts not listed as dependency.

                distclean target used Makefile after deleting, and many fixes

                to man pages.

                Saad Mufti  noted bug in how C library

                handled polling (when handling multiple fds).

                Jeff Bowyer noted more autoexpect bugs.

7/22/95 5.17.6  More features added to autoexpect (now version 1.3).

                Sanjay  noted bug in TCLH config macro

                which caused it to use 7.3 instead of 7.4.

                Rodney Barnett  noted expectd.proto had a

                few refs to interact_out where it should've had expect_out.

                Terry Rhodes  noted that Expect returned a 0

                exit status upon syntax error unlike tclsh and wish.

                Fred Obermann  noted that Unixware 2.01

                native development tools don't permit configure to find memcpy

                because memcpy is handled specially by the compiler and it

                complains when it finds configure's default test with no args.

                Changed to a hand-crafted test with args.

7/12/95 5.17.5  Jeff Bowyer  noted minor bugs in autoexpect.

                Rob Saul  noted that configure failed on SCO OSR5

                because trap requested by Cygnus (to allow config in bg) used

                higher traps than SCO sh knows about.

                Changed "can't happen" to "xmkmf is broken" when configure

                fails to compile simple C-Tk program.

                John H. Chauvin  noted exp_tty_current and

                cooked raised multiple def errors on SGI 5.3 with native cc.

7/9/95  5.17.4  Wolfhardt Lotz  noted Solaris

                doesn't do case-insensitive man page lookups so I lowerized

                the beginning of the .SH lines.

                Henry Spencer noted unbackslashed quotes in the autoexpect

                boilerplate.

7/3/95  5.17.3  Modified VARARGS decls to support new Tcl 7.4 definitions.

                Fine-tuned aclocal so that it would prefer later versions.

                Added autoexpect example and man page.

6/30/95 5.17.2  select-based dsleep() was returning an internal expect-style

                return code instead of a Tcl-style.

6/30/95 5.17.1  Kannan Varadhan  noted aclocal didn't

                look in right directories to find Tk.

6/30/95 5.17.0  Modified regexp interfaces to support Tcl 7.4b4.

                Mods from Tony Isles  for Sequent Dynix/ptx

                V2.1.5 (which is really old).

                Michael Schumacher  noted that Solaris

                2.4 header files require __EXTENSIONS__ for all sorts of

                traditional but non-standard definitions.

                Modified aclocal to support new Tcl/Tk library names.

                George Forman  requested support in

                C lib for fds that already exist.  I added exp_spawnfd.

                Fixed bug preventing signal rearming on Linux (using SV-style

                signal handling).

                Wayne Christopher  noted missing interp

                in call to exp_error.

                Added null support to interact's exact matching.

                Bruce Jerrick noted INSTALL was being used rather than

                INSTALL_PROGRAM/DATA.

                Dennis Ferguson  noted that on Solaris 2.4

                close(pty) occasionally returns EINVAL.

                Added tests so that if we can't get a pty, we can give the user

                much more help with what to do about it.

                Steven Byrnes noted that Solaris has replaced TIOCCONS with

                SRIOCISREDIR interface.

                Technically speaking, interact shouldn't do buffer-shuffling

                but I've added as a fail-safe mechanism to catch people who

                use preposterous patterns.

                Alan Heckert  noted missing decl in

                Convex pty support.

                Fixed all expectk examples for Tk4.

                Bryan S. So  noted that interact -o eof failed

                if an unbuffered pattern was partially in progress.

                Added -timeout flag to expect command to override timeout var.

                John Pfuntner  noted that OpenMVS did

                not notice @ inside of Makefile SETUID macro as suppression

                but instead treated it as part of the program name.

                Jim Porter  noted that exp_free_i freed

                the variable name even if not allocated.

                Yet more mods to aclocal and various .in files from Rob Savoye.

4/21/95 5.16.3  Matija Grabnar  noted that sleep maxed

                out after about 36 minutes.  Turned out to be a poor assumption

                in some interfacing code.

4/19/95 5.16.2  rbd  noted tcl_RcFileName multiply defined

                when compiling with Tk4.

4/16/95 5.16.1  Robert Nicholson  noted NextStep's

                sys/wait.h is not POSIX-like so WNOHANG fails to get a defn.

                Alexandre Rafalovitch  discovered

                example on dislocate man page didn't work.  I fixed it.

4/8/95  5.16.0  gcc 2.3.3 complains about internal errors so I figure: time to

                upgrade.  Switched to Cygnus 2.6-95q1.  Works now but now

                complains about wait status.  I trashed all the gory wait

                status configure code and adopted autoconf's suggestion about

                refusing to use sys/wait.h if not POSIX.1 compatible.  Nice!

                Jeffrey C Honig  requested a -gmt

                flag for timestamp command.

                Chuck Ocheret  noted that expect -pty

                fails.  Problem is that Tcl's exec blindly closes all the fds

                between 3 and its own highest fd.  See comments in code.

                Loris Caren  noted eof in fg bombs on

                Linux.  Turns out to be analogous to eof in bg problem fixed

                in 5.14.0.

                Upgraded to autoconf 2.3.  Continued making changed to config

                script to take advantage of autoconf 2 capabilities.

4/1/95  5.15.4  Steve Simmons noted .x remnant from earlier dir install proc.

3/31/95 5.15.3  Forgot to export TCLHDIR defn when configuring debugger.

3/29/95 5.15.2  Steve Simmons  noted Makefile multiple defined

                distclean and it might be nice to provide aclocal.m4 even

                though it isn't normally used.

                cevans@resdev1.ppco.com added prompts to passmass for AIX.

3/27/95 5.15.1  Fixed tkterm script - inadvertently left tic debugging on.

                Also add support for Ctrl-space and Ctrl-@ as requested by

                Zbigniew Wieckowski .

                Larry Virden asked that configure also check for .so libs.

3/23/95 5.15.0  Everitt Beers  noted that Linux doesn't

                support kill -STOP 0.  Changed 0 to [pid].

                zhengping (z.) you  found bug where a bg expect did

                not rearm a spawn id after a first bg expect (and another one)

                to clear it.

                Elliott Wolin  noted that tkterm

                complained if tic wasn't found.  I'll have it override the

                user misconfig in that case.  Also noted that interact failed

                on AIX.  Evidentally, my new config tests for ISC found that

                AIX looked just like it.  Added additional test for tcsetattr

                to distinguish them.

                Rob Savoye asked for Dbg config.in to be distributed.  Rob

                supplied numerous other mods: install-sh replaced install.sh,

                mkinstalldirs, testsuite mods, new aclocal.m4, support for

                recursive make.

                Fixed bugs in configuration of debugger.

                Disabled configure's file-caching.

                Kannan Varadhan  noted incorrect diag reporting

                TCLHDIR in configure.

                Marty Olevitch  noted that DEC Alpha

                did not sleep correctly because configure didn't find sleep

                and found poll (which is broken).  Problem turned out to be a

                bug in autoconf's AC_CHECK_FUNC.  Got patch from Jim Meyering

                Fixed config probs for Edward Huie  on Mac SE/30,

                System 7.1, Tenon Intersystems' MachTen 2.1.1-G (BSD 4.3 on

                Mach kernel) and MachTen X11R4 3.1.

                Moved libraries forward in configure to allow for AC_CHECK_FUNC

                to succeed when funcs are in other libraries.

                Made configure test for Linux and unset CFLAGS=-g if so.

2/25/95 5.14.3  Larry Virden noted configure was missing brackets in raw shell

                cmds evidentally due to m4 interpretation.

2/24/95 5.14.2  Larry Virden noted configure was not correctly rewriting from

                --(exec-)prefix.  Due to new autoconf.  Also noted glob was

                finding tclX directory.

                Hal Peterson noted that because configure now actually attempts

                a link before using a library, the code to check for -ltk would

                have to worry about all the other utility libraries first.

2/23/95 5.14.1  Hal Peterson noted that configure.in checked incorrectly for

                tcllib.

2/22/95 5.14.0  Jamal  noted Linux has tic in a

                different place than on my system - affected tkterm script.

                Xiaokun Zhu  noted problem on DEC

                Alpha OSF/1.3 evidentally due to backwards decl of index macro.

                Greg McFarlane  noted that large args in

                send cmd cannot be passed blindly to exp_error.

                david d `zoo' zuhn  requested modifying

                configure so that it did not require Tcl/Tk to be built - only

                configured.  This means that it may not find installed

                libraries.  Hopefully, this won't cause anyone problems but its

                not my preference.

                Fixed error which caused spurious eof when changing patterns

                in expect_bg.

                Moved to autoconf-2.1 and m4-1.4.  Rewrote a LOT of the config

                file.  Finally got my hands on an ISC box and fixed configure

                for that.

                Tony Booker  provides mods for Sequent ptx 2

                and 4.

                Jeffrey Friedl  provided fixes for

                timezone handling in config and exp_strf.c.

                David Schmitt  noted that library did

                not detect eof on HP.  I didn't think this was necessary for

                read() but it evidentally is.  I added the support for raw fds

                although it is not obvious to me how to do it for FILEs.

                James Carter  noted expect_after couldn't

                worked in the exp_bg because I had accidentally written BEFORE

                instead of AFTER when checking the cases.  He also found that

                the eof body could be trashed in an exp_bg.

                Ousterhout apologized for the Tcl7.4 change I noted in 5.13.1

                and said he will undo it.

                Eric Frias  found library bombed after timeouts.

                exp_match_end was not updated - which makes sense since there

                was no match - however the following expect call assumed that

                exp_match_end was meaningful in order to do its buffer

                shuffling.

                Jonathan Kamens supplied new configure test for REARM_SIG after

                noting old could fail if limit prevented creation of core file.

                He also noted REARM_SIG had accidentally been commented out

                of cf file.

                Vincent D. Skahan  noted that

                Apollo's stty reads stdout and doesn't complain if its bogus.

                Yoad Grinberg  noted that SIGCHLD does

                not work for forked processes, only spawned processes.  Fixed

                this and added counting to make sure none get lost.

                Hal Peterson contributed mods for Unicos.  He noted that

                configure should be more careful adding libs to the link line.

                On the Cray, non-existent libs generate warnings which are not

                detected by configure but which annoy make.

                Bela Gazdy  noted /etc/resolv.conf

                misspelled in kibitz.

                Rainer Wilcke noted that "send -null/break" mishandled return

                code, and these and send/expect_tty were not in man page.

                Dvorak example was missing -- in send -.

1/12/95 5.13.2  Peter Wassenaar  noted that kibitz

                didn't work on AIX.  My fixcat script assumed that AIX's cat

                was like HP's cat - buffered by default.

1/7/95  5.13.1  Marc Bouron  noted I forgot to

                add virterm to distribution.

                Marc W. Mengel  noted that configure

                must be run in the foreground due to the stty tests.  Added

                this to documentation.

                Modified interpreter to account for the change in Tcl7.4 which

                forces Tcl_RecordAndEval to call Tcl_GlobalEval instead of

                Tcl_Eval.

                Changed ptys to be initialized based on current tty setting

                rather than original tty setting.

                Stephen Melvin  noted that set -e is the real

                problem with ash (see 5.13).  I bet "[" is returning a value

                and triggering it.  It appears that the script can live without

                the set, so out it goes.

                Braun Brelin  noted pipe allocs in spawn

                could fail with meaningless error message.

12/15/94 5.13.0 Synchronize with appearance of "Exploring Expect".  This

                distribution corresponds to the book both in description of

                Expect and in containing all the substantive examples.

                Graham Mark  noted that his Cray (Unicos 7.0.6.1)

                didn't recognize TCSETCTTY.  Since this was in some Cray-

                specific code, I guess Unicos must have changed some .h files.

                I made it include either termios or termio.  It, at least,

                works on our Cray (Unicos 8.0.2.4).

                Robert Withrow  noted that FreeBSD 1.1.5.1

                supplied union wait but waitpid doesn't use it!  So I modified

                configure to be smarter.  He also noted that its /bin/sh is

                really ash which blows up on install.sh.  It appears that it

                doesn't handle uninitialized parameters correctly.  I'm not

                going to fix this because having a broken /bin/sh is so awful

                probably other things are breaking too.  He did note that it

                worked if he switched to bash or the native install, but that

                blows the whole point of install.sh - that we have found too

                much variation in native installs.  Rather than try and figure

                out everyone's variation, we'd like to simplify our life and

                use this common, simple-to-understand sh script.

                Added more example scripts: Adrian Mariano's virterm (like

                expect_term but without relying on Tk), gethostbyaddr, and

                expectd.proto for telnet daemon.

                Matt DiMeo  noted that expect_background

                failed to detect eof on HP.  I had forgotten to pass the mask.

                Josef Sachs noted that expect_background put Tk's event handler

                in an infinite loop if it was listening to a pipeline that was

                killed.  I had aborted the cleanup procedure if Tcl's close

                reported an error.  That was a mistake.

                Rick Lyons  noted a bug.  C lib

                expect would turn a normal read into a poll if remtime reached

                zero on the nose.

                Added ResetResult to Exp_Init to clean up diags in Expectk.

                Made GENFUNCs return -1 on error as per ParseArgv's convention.

11/13/94 5.12.0 Alon Albert noted that in clib, exp_match_end should be init'd

                to exp_buffer before trying to match the pattern - if the

                expect doesn't produce a match, exp_match_end is incorrect and

                will be wrong for subsequent expects.

                Steven Diamond noted that fg expect did not react to a change

                in an indirect spawn id list if it was just waiting for I/O

                (rather than looping in exp_continue).

                Wait fix in previous version broke system() whose return value

                is horribly overloaded.

11/10/94 5.11.0 Stephen Fitzpatrick  noted that NeXT wait

                macros do not accept int wait status.  Switched to using Tcl's

                detection of wait status type.

                Made log_file -leaveopen leave file id open until close like

                spawn -leaveopen did.

                Bruce Jerrick  noted public include dir

                wasn't getting created.

                Karl Vogel noted 1) Pyramid has index instead of strchr, strf.c

                needs sys/time.h instead of time.h in strf.c, needs to call

                timezone(), and stty reads stdout but usual stty test fails.

                Made expect_out(spawn_id) always be written to assist people

                who want to log different procs to different files.  This is

                no longer an efficiency problem because interact can do so

                much more then it used to.  Made full_buffer condition write

                forgotten chars even when full_buffer isn't explicitly

                specified.

                Bert Robben  noted that the

                debugger needs to know about the presence of stdlib.h.  I was

                hoping to avoid this because it's a pain getting configure to

                call another configure.

                Rainer Wilcke provide several improvements for xkibitz and man

                page.

10/6/94 5.10.0  Moved example files around.  Added password generation to

                tkpasswd.  Created standalone script to generate and set

                passwords - good for all those adduser shell scripts.

                Rick Cady  found a bug when switching log

                files.
