* exp_inter.c: [https://sourceforge.net/p/expect/patches/22/]
Fix interact bug - handle reads of 0 length on
non-blocking channels by explicitly checking if the channel
is non-blocking. Fix by Jack Bates.
* expect.c: [https://sourceforge.net/p/expect/patches/21/]
Fix eof bug introduced with previous bug fix - ensure that data
received just before an eof is processed. Fix by Sergei Golovan.
2014-05-01 Andreas Kupries <[email protected]>
* exp_main_sub.c: Updated EXP_VERSION to 5.45.3
* configure, configure.in: Updated expect to version 5.45.3
* expect.man [http://sourceforge.net/p/expect/bugs/86/]. Report
and fix by Vitezlav Crhonek.
* expect.c [http://sourceforge.net/p/expect/bugs/76/]. Report and
fix by Mutsuhito Iikura. On finding a full buffer during
matching the sliding window mechanism slides too far, truncating
the whole buffer and preventing matches across the boundary. Fix
is shortening the slide distance (slide only one 1/3).
* expect.c: [http://sourceforge.net/p/expect/patches/18/]. Report
and fix both by Nils Carlson <[email protected]>.
Replaced a cc==0 check with proper Tcl_Eof() check.
2013-11-04 Andreas Kupries <[email protected]>
* tclconfig/tcl.m4: [http://sourceforge.net/p/expect/patches/17/]
* configure: Extended Tcl header detection for OS X Mountain Lion.
* exp_main_sub.c: Updated EXP_VERSION to 5.45.2
* configure, configure.in: Updated expect to version 5.45.2
* expect.c: [http://sourceforge.net/p/expect/patches/16/]. Report
and fix both by Per Cederqvist. Replaced a memcpy with memmove
as the latter properly handles overlapping memory, whereas the
original code does not.
2012-08-15 Andreas Kupries <[email protected]>
* exp_main_sub.c: Updated EXP_VERSION to 5.45.1
* configure, configure.in: Updated expect to version 5.45.1
* exp_chan.c: Applied patch sent in by Ogawa Hirofumi
<[email protected]>. The patch fixes a problem when
talking a tty where the writer has died. Some operating systems
report the condition as EIO with nothing read, while this
actually an EOF. Without the patch the returned data is
incomplete due to the error reported immediately and dropping
data in buffers.
2012-05-16 Andreas Kupries <[email protected]>
* exp_chan.c: [Bug 3526461]: Applied patch by Michael Cleverly
<[email protected]> fixing a problem with the
iteration over the expect channel list where the loop code may
modify the list, breaking the iterator.
* exp_chan.c: [Bug 3526707]: Applied patch by Michael Cleverly
* exp_command.h: <[email protected]> fixing problem
* expect.c: with an insufficient test for a lost channel in
exp_background_channelhandler.
2010-10-26 Andreas Kupries <[email protected]>
* expect.c: [Bug 3095935]: Convert #bytes information to #chars to
prevent later code to fail when copying strings around and
miscalculating how much to copy, for strings containing
non-ASCII utf chars.
2010-09-30 Andreas Kupries <[email protected]>
* example/autopasswd: Updated to use tclsh in PATH, and 'package
* example/chess.exp: require Expect'. Obsoletes fixline1.

* mkinstalldirs: Removed unused file.
* tclconfig/README.txt: Removed unused file.
* testsuite/config/: Removed contents of unused directory.
* test/.Sanitize: Removed unused file.
2010-09-17 Jeff Hobbs <[email protected]>
* Makefile.in: improved make dist target to include the necessary
files, and remove old dist_orig.
Enable Makefile regen target
2010-09-16 Jeff Hobbs <[email protected]>
* configure: regen with ac-2.59
* tclconfig/tcl.m4: update for correct LDFLAGS on HP-UX
* Makefile.in (expect): use TEA LDFLAGS instead of tclConfig.sh to
build expect executable
2010-09-01 Andreas Kupries <[email protected]>
* Makefile.in: [Bug 865278] Semi-applied Don Porter's patch adding
code which prevents the package from registering with Tcl
interpreters which cannot load it, i.e. below the version it was
compiled against. Semi because the pkgIndex.in in his patch is
not used, the pkgIndex.tcl is generated by the Makefile(.in).
* pkgIndex.in: Removed. File not used.
2010-08-31 Andreas Kupries <[email protected]>
* Various cleanups, local patches of ActiveState.
* exp_clib.c: Remove local copy of Tcl_ErrnoMsg().
* exp_inter.c: Hack access to TCL_REG_BOSONLY when not present,
became private with Tcl 8.5 and higher.
* expect.h: Remove the local fiddling with the memory allocation
and panic macros.
* Dbg.c: [Bug 2972727]: Applied the parts of Larry Virden's patch
which were still current. Most of it applied to the partially
ansified sources we had in trunk for a time and where errors in
that set of changes, thus out of date now.
* example/unbuffer: [Bug 2949748]: Applied patch by Vitezslav
Crhonek <[email protected]> to prevent unbuffer
from eating the exit code of the command it ran (regular mode
only, not -p). Slightly modified, I removed the superfluous
'eval' used to invoke 'wait', invoking it directly.
2010-08-27 Jeff Hobbs <[email protected]>
* retoglob.c: Fail if the generated glob contains more than
two asterisks. Fixes [Expect SF Bug 3010684] (cederqvist)
* exp_main_sub.c: add return to silence compiler warning.
Updated EXP_VERSION to 5.45.0
* config.guess, config.sub, expect.m4 (removed):
* configure, configure.in, tclconfig/tcl.m4: Update to TEA 3.9
* Makefile.in, aclocal.m4: Partial cleanup of the build system.
* testsuite/Makefile.in: Remove unused EXP_ from configure.in
* testsuite/aclocal.m4: and no longer use Tk.
* testsuite/configure: Update testsuite bits to use TEA info.
* testsuite/configure.in:
Update expect to version 5.45
* Dbg.c: account for removal of tcldbgcf.h
* DbgMkfl.in, Dbgconfig.in, Dbgconfigure, DbgpkgInd.in (removed):
* tcldbgcf.h.in (removed): removed Dbg debugger subcomponent as it
no longer built and debugger functionality is included in expect
library and binary
* pty_termios.c: add HAVE_STRING_H include string.h
* exp_trap.c: add HAVE_STRING_H include string.h
* expectk.man, exp_main_tk.c (removed): expectk no longer
built. Use tclsh with package require Tk and Expect instead.
* tests/all.tcl: add package require Expect
* example/archie, example/autoexpect: minor code cleanup
* example/tkpasswd, example/tknewsbiff, example/tkterm: use
package require statements in lieu of expectk
2009-11-03 Andreas Kupries <[email protected]>
* exp_command.c (Exp_SpawnObjCmd): [Expect SF Bug 2891422]. Fixed
error message when the command to spawn could not be executed.
Tried to use a Tcl_Obj* as argument for a %s. Replaced with the
correct char* variable. Thanks to Elchonon Edelson
<[email protected]> for the report.
[Expect SF Bug 2891563] Ditto for the same type of bug when
emitting error 'usage: -ignore unknown signal name'. The
remainder of the exp_error calls are ok however.
* configure.in: Bumped version to 5.44.1.15.
* configure: Regen'd, autoconf 2.59.
2009-07-14 Andreas Kupries <[email protected]>
* exp_clib.c (TclRegComp): Fixed memory leak reported by
<[email protected]> in [Expect SF Bug 2814263].
2009-06-22 Andreas Kupries <[email protected]>
* pty_unicos.c (pty_stty): Fixed missing double-quotes for sprint
formatting strings. Thanks to <[email protected]>
for the report, i.e. [Expect SF Bug 2809496].
2009-06-18 Andreas Kupries <[email protected]>
* exp_command.c (Exp_LogFileObjCmd): Fix argument parsing logic
error in the log_file command breaking the use of options -open
and -leaveopen. Applied patch supplied by Andy Belsey
<[email protected]>. With thanks for both the analysis of
the problem and the patch.
* configure.in: Bumped version to 5.44.1.14.
* configure: Regen'd, autoconf 2.59.
2009-05-27 Andreas Kupries <[email protected]>
* exp_tty.c (Exp_SttyCmd, Exp_SystemCmd): Applied patch by
Reinhard Max ([email protected]) fixing buffer-overflows in the 'stty'
command due to an off-by-one error in the buffer size. See the
bugs https://bugzilla.novell.com/show_bug.cgi?id=506873
and https://bugzilla.novell.com/show_bug.cgi?id=501291
* configure.in: Bumped version to 5.44.1.13.
* configure: Regen'd, autoconf 2.59.
2009-05-06 Andreas Kupries <[email protected]>
* retoglob.c: Accepted the patch by Mike Cumings
<[email protected]> fixing [Expect SF Bug 13179].
The updated code checks a (?...) sequence that it contains only
ARE options before processing it as such. This prevents the
misinterpretation of non-capturing paren groups as ARe options
with subsequent segmentation fault.
* configure.in: Bumped version to 5.44.1.12.
* configure: Regen'd, autoconf 2.59.
2008-09-30 Andreas Kupries <[email protected]>
* configure.in: Bumped version to 5.44.1.11.
* configure: Regen'd, autoconf 2.59.
* exp_command.c (Exp_OverlayObjCmd): Fixed [Expect SF Bug 2127456]
reported by <[email protected]>, with thanks. Changed
retrieval of command from objv[0] (== 'overlay' itself), to
objv[i] containing the actual user command.
* expect.c (string_case_first, string_first, eval_case_string):
Applied patch supplied by Andy Belsey <[email protected]>
fixing the seg.fault in 'expect -exact'. With thanks for both
the analysis of the problem and the patch. See also [Expect SF
Bug 2114547].
2008-08-28 Andreas Kupries <[email protected]>
* exp_trap.c (tophalf): Fixed inverted condition setting the
interpreter used for trap handling to NULL, causing a crash when
trying to handle ^C. This fixes [SF Bug 1757471] reported by
Matthias Kraft <[email protected]>.
* configure.in: Bumped version to 5.44.1.10.
* configure: Regen'd, autoconf 2.59.
2008-08-18 Jeff Hobbs <[email protected]>
* exp_main_sub.c (exp_interpreter): cleaner handling of commandPtr
to prevent crash. (das)
2008-06-03 Andreas Kupries <[email protected]>
* exp_glob.c (Exp_StringCaseMatch2): Fixed bug in the handling of
glob classes, see [SF Bug 1873404]. The code tried to match the
closing bracket of a class in the input because it was not
properly skipped after the class was matched successfully.
Additional trace output added.
* configure.in: Bumped version to 5.44.1.9.
* configure: Regen'd, autoconf 2.59.
2008-05-05 Andreas Kupries <[email protected]>
* exp_pty.c: Minimal ansification of function definitions to match
them to their prototypes where promoted types are otherwise
causing a mismatch for some compilers, like AIX in 64bit mode.
* configure.in: Bumped version to 5.44.1.8.
* configure: Regen'd, autoconf 2.59.
2008-04-03 Andreas Kupries <[email protected]>
* configure.in: Bumped version to 5.44.1.7.
* configure: Regen'd, autoconf 2.59.
* The following set of changes was sent our way by Reinhard Max
* exp_command.c: Fixed more compiler warnings, and started
* exp_command.h: to ansify the code base, beginning with
* exp_inter.c: the introduction of proper function prototypes.
* exp_main_exp.c:
* exp_pty.h:
* exp_tty.c:
* exp_tty.h:
* exp_win.c:
* expect.c:
* pty_termios.c:
* retoglob.c:
2008-04-03 Andreas Kupries <[email protected]>
* configure.in: Bumped version to 5.44.1.6.
* configure: Regen'd, autoconf 2.59.
* The following set of changes was sent our way by Reinhard Max
* configure.in: Fixed checking of stty on linux, do not restrict
to specific cpu's. Further try with stdin, and stdin redirected
to /dev/tty when determining if stdout is read.
* testsuite/configure.in: Brought up to TEA 3.5.
* testsuite/aclocal.m4: New file, to import the TEA definitions.
* Dbg.c: Added missed CONST in declaration and definition of
'debugger_trap'.
* exp_command.c: Fixed pointer aliasing trouble with
'Tcl_DetachPids', and added the missing initialization of the
command string in the 'overlay' command.
* expect.c: Fixed missing initialization of 'simple_start' element
of 'ecase'.
* exp_inter.c: Fixed bogus use of 'slen' in 'intMatch'. The
relevant string is Tcl_Unichar, not Utf.
* Makefile.in: Replaced bogus INSTALL_ROOT with DESTDIR, and added
missing DESTDIR references to the target for the installation of
the manpages.
2008-02-27 Andreas Kupries <[email protected]>
* expect.c: Fixed refcounting error when parsing a single expect
* configure.in: argument into a list of patterns and
* configure: actions. Updated the version number to 5.44.1.5.
* Dbg.c: Added missing 'return TCL_OK' to debugger_trap.
2007-12-13 Jeff Hobbs <[email protected]>
* exp_log.c (expStdoutLogU): correct which buf is output.
* exp_command.c (Exp_SendLogObjCmd): fix '--' handling
(Exp_SendObjCmd): fix '--' handling to expect last argument
2007-09-24 Andreas Kupries <[email protected]>
* exp_inter.c: Changed inclusion of tcl.h to tclInt.h to get the
* expect.c: definition of TCL_REG_BOSONLY, which was moved to that
header in Tcl 8.5. Ditto for expect.c, for the macro
TclUtfToUniChar (was a function in 8.4). Expect now compiles
again for both Tcl 8.4 and 8.5.
* configure.in: Bumped version to 5.44.1.4.
* configure: Regenerated.
2007-09-19 Andreas Kupries <[email protected]>
* retoglob.c (EMITC): Keep the characters '^' and '$' quoted as
well, we do not wish to invoke their special interpretation by
the Expect glob matcher.
* configure.in: Bumped version to 5.44.1.3.
* configure: Regenerated.
2007-08-09 Andreas Kupries <[email protected]>
* retoglob.c: We had ExpChopNested and ExpBackslash locally
ansified (prototypes) to avoid a compiler error on AIX (type
promotion trouble). This now integrated into the mainline
sources, conditional to AIX.
* expect.c (Exp_TimestampObjCmd): Fixed argument processing broken
by objc,objv conversion. Tried to use command name as the
argument for -seconds. Also did not detect when one argument to
many was specified.
* configure.in: Bumped version to 5.44.1.2.
* configure: Regenerated.
2007-07-17 Andreas Kupries <[email protected]>
* expect.c: Circumvented problems with the C compiler by use of a
temporary variable to hold the unicode pointer of a glob
pattern. The computed pattern length given to
Exp_StringCaseMatch was bogus.
* exp_glob.c: Added tracing of the glob matcher internals (Can be
enabled by define EXP_INTERNAL_TRACE_GLOB). Fixed bug in a guard
condition in the optimized handling of '*'. The bad condition
caused the code to miss possible matches at the beginning of the
input (first char).
* tests/expect.test: Added tests which check the glob matcher and
RE gate keeping.
* configure.in: Bumped to 5.44.1.1 to separate this from the
regular 5.44.1 sources.
* configure: Regenerated.
2007-07-12 Andreas Kupries <[email protected]>
* expect.c: Found bugs mismanaging input and pattern in the
* exp_glob.c: updated glob matcher. We cannot check for '\0'
anymore to find the end of the string, these are counted
arrays now. Rewritten to use sentinel pointers.
2007-07-11 Andreas Kupries <[email protected]>
* exp_chan.c: Converted the buffering system from UTF-8 in Tcl_Obj
* exp_command.h: to UTF-16 C-array, to avoid the repeated conversion
* expect.c: of the input from utf-8 to utf-16. Updated the glob
* exp_glob.c: matching code to use the same tricks for speed which
* exp_inter.c: are used by the Tcl core. Extended the regexp
* exp_log.c: matching path with a glob matcher which uses a gate
* exp_log.h: keeper glob pattern to weed out most non-candidates
* retoglob.c (New file): in a speedy manner. Regexp matching now
has to be done only for the small number of candidates
identified by the gate keeper. Overall speed improvement as glob
matching is faster than regexp matching. Added code translating
regular expressions into their gate keeper glob pattern.
* Dbg.c: Converted the lot of argc,argv based command
* exp_command.c: implementations over to objc,objv.
* expect.c:
* exp_main_sub.c:
* Dbg.c: Cleaned up the direct access to interp->result,
* exp_command.c: replaced with the proper functions and
* expect.c: Tcl_Obj's.
* exp_main_exp.c:
* exp_main_sub.c:
* exp_main_tk.c:
* exp_prog.h:
* exp_trap.c:
* exp_tty.c:
* exp_win.c:
* exp_win.h:
* tests/cat.test: Added proper 'package require Expect'
* tests/expect.test: to the test setup code (JeffH).
* tests/logfile.test:
* tests/pid.test:
* tests/send.test:
* tests/spawn.test:
* tests/stty.test:
* exp_command.c: Reformatted overlong lines, whitespace,
* expect.c: comments. Added braces to some if-constructs.
* exp_inter.c: Reworked if-constructs interleaved with
* exp_tty.c: #if for better formatting in emacs.
* Dbg.c: Added note about unhandled cases in a switch.
* exp_chan.c: Added code to suppress unhandled warning for
unreachable code.
* exp_command.c: Removed unused variable.
* expect.c: Removed unused static function, added code to suppress
unhandled warning for unreachable code.
* exp_command.c: Fixed typo in comment.
2007-06-28 Andreas Kupries <[email protected]>
* Merged changes from the official version 5.44.1 of expect into
the SF sources. See the details below.
--------------------
Marius Schamsula <[email protected]> reported tclconfig
missing, evidentally for new TEA.
Lots of massaging to fix TEAification of Makefile and configure
including that version numbers will now be full three part.
Daniel Wong <[email protected]> noted the home page
should note that Wikipedia has a very readable entry for Expect.
Andre Alves <[email protected]> noted passmass needed some
fixes to handle Solaris 9 passwd prompt changes.
Andreas fixed several things: changes to better support TEA, fix
debugger interaction with nonblocking mode, and probably other
things I'm overlooking.
Martin Dietze <[email protected]> noted that autoconf 2.59 is
confused by C comment after undefs in expect_cf.h.in.
Added additional code to unbuffer -p so that if a process
earlier in the pipeline exits, unbuffer attempts to recover any
remaining output from the spawned proc before unbuffer itself
exits.
Jeffrey Hobbs noted that once stty was called, a bg'd script
would be suspended at exit. Turned out to be overaggressive
code in stty that recorded what 'damage' the user might have
caused when calling stty in the first place.
Jens Petersen provided patch to make setpgrp configure better on
some Linux systems.
Added example/getpassck script to test for getpass bug.
multixterm had debugging stuff leftover ("hello").
--------------------
2006-02-27 Andreas Kupries <[email protected]>
* exp_main_sub.c: Added command 'exp_configure' for magic configuration.
* exp_command.c: Accepts option -strictwrite. Default is 0, ignoring
* exp_chan.c: write errors (compatible to 5.41). Setting to 1 re-
* expect_tcl.h: activates 5.42 behaviour.
2006-01-25 Jeff Hobbs <[email protected]>
* tclconfig/tcl.m4, configure: Fix LD_SEARCH_FLAGS setting in tcl.m4
* example/unbuffer: whitespace police
* example/beer.exp: brace exprs
* expect.man: use clock instead of exec date, minor nroff fixes.
2006-01-24 Andreas Kupries <[email protected]>
* tclconfig/tcl.m4: Updated to TEA 3.5
* configure.in: Ditto.
* configure: Regenerated.
2006-01-10 Jeff Hobbs <[email protected]>
* tests/expect.test: ensure iso8859-1 for /tmp/null (steffen).
2005-09-19 Andreas Kupries <[email protected]>
* exp_chan.c (ExpOutputProc): Added guard to intercept and ignore
empty write operations, i.e. operations trying to write zero
bytes.
2005-09-09 Andreas Kupries <[email protected]>
* exp_chan.c (ExpBlockModeProc): No, stdin is not ok (See last
entry). Fixed.
2005-07-07 Andreas Kupries <[email protected]>
* exp_chan.c (ExpBlockModeProc): [Expect SF Bug 1108551]. Excluded
manipulation of the blocking status for stdin/stderr. This is
handled by the Tcl core itself and we must absolutely not pull
the rug out from under it. The standard setting to non-blocking
will mess with the core which had them set to blocking, and
makes all its decisions based on that assumption. Setting to
non-blocking can cause hangs and crashes. Stdin is ok however,
apparently.
This problem was introduced at '2004-06-14'.
2005-06-22 Andreas Kupries <[email protected]>
* exp_chan.c: Fixed bug causing crash of expect on exit when a
* exp_command.c: Tcl channel is used with -(leave)open more than
* exp_command.h: once. It tried to close such channels multiple
times, going through already freed memory. Added data structures
to track and refcount all such channels, to close them only when
the last user goes away.
2005-06-09 Andreas Kupries <[email protected]>
* Makefile.in: Upgraded build system to TEA 3.2.
* configure.in:
* config.guess:
* config.sub
* exp_main_sub.c:
* aclocal.m4:
2005-03-29 Andreas Kupries <[email protected]>
* exp_chan.c: Fixed problem with debugger introduced at '2004-06-14'.
* tcldbg.h: For a nonblocking stdin the debugger blowed up on the
* Dbg.c: empty reads it could get, exiting the application. I
guess that this was an implicit 'panic'. Fix:
- Split ExpBlockmodeProc into high- and lowlevel
code, the latter for use by the debugger. The
high-level code tells the debugger which state
stdin is in (doing this explicitly because if
FIONBIO is used it is not possible to query the fd
directly, and I saw no reason to #ifdef for fcntl
which can).
- Debugger now exports a function for use by the
blockmode proc, and in each interaction it checks
for nonblocking input, forces blocking if
necessary. At the end of each interaction the true
mode is restored. Both operations use the
low-level blockmode code.
2005-03-07 Jeff Hobbs <[email protected]>
* exp_tty.c (Exp_SttyCmd): fix from Libes that controlling
terminal check example (book p372) by restricting set of
exp_ioctled_devtty variable.
2005-02-15 Andreas Kupries <[email protected]>
* Merged changes from the official versions 5.42.1 and 5.43.0 of
expect into the SF sources. See the details below.
--------------------
Martin Forssen <[email protected]> fixed bug in ExpOutputProc
that caused misbehavior during partial writes.
Someone noted that gets stdin behaves differently (returns -1
immediately) from tclsh because with 5.42, stdin is unblocked by
defaults.
Robroy Gregg <[email protected]> noted that expect_background
ignores timeouts. Added to documentation.
Jens Peterson <[email protected]> provided patch for
"mkpasswd -vo".
Gary Bliesener <[email protected]> noted that
multixterm failed on his system which had an old Tk that didn't
support the Tk package.
Removed beta designation.
Daniel A. Steffen <[email protected]> provided patch for
MacOS to avoid panic-redefinition.
--------------------
2005-01-21 Andreas Kupries <[email protected]>
* exp_inter.c: Changed all uses of 'time(3)' to Tcl_GetTime. IOW
* expect.c: go through the abstract core API instead of
directly acessing OS time. This makes the code
dependent on Tcl 8.4, as Tcl_GetTime was not public
before. See TIP #73 for its introduction into the
public API. As for the reason behind _this_ change
see TIP #233. Our change here now causes Expect to
be automatically in sync with any virtualization
set up in the core.
2004-08-19 Andreas Kupries <[email protected]>
* exp_chan.c (ExpOutputProc): Added code posted by Don on
c.l.t. to handle interrupted system calls (EAGAIN).
2004-07-15 Andreas Kupries <[email protected]>
* Merged changes from the official version 5.42b0 of expect into
the SF sources. See details below.
--------------------
Alexander Doktorovich <[email protected]>
wanted to use Expect as a filter. This is possible but 'too
hard'. To make it easier, added close_on_eof command to control
whether expect/interact automatically close the channel on eof.
This should simplify/enable other scripts.
Kurt Heberlein <[email protected]> noted that Expect would
hang. Andreas tracked it down to a change in Tcl such that when
Tcl had data left in its buffers, it would check for more data
rather than returning what it had to Expect first. If no data
was forthcoming then Tcl would hang because the pty driver runs
in blocked mode. Recoded to use nonblocking mode.
Yi Luo <[email protected]> noted that multixterm xterms were
reporting the parent's X window ids (via the WINDOWID env
variable) instead of the new ones.
Dick Van Deun <[email protected]> noted that kibitz expects
to find write in /bin but it is in /usr/bin on Slackware. Seems
safe to drop the prefix.
Steve Lee <[email protected]> noted that building Expect failed
on Linux when built from scratch because stty ends up in
/usr/local/bin rather than the assumed /bin. Added code to
support this.
--------------------
2004-06-14 Andreas Kupries <[email protected]>
* exp_chan.c: Integrated the block mode proc I got by mail from
Don Libes into the channel driver. This fixes an error with
expect hanging on some input if the situation is just
right^Hwrong. Basically if the buffers in driver, Tcl IO core
and Expect itself are aligned just so it can cause Expect to
block in all call to the OS for more data even if all the data
it needs is in ts buffers. Because the driver is blocking and
the Tcl core was told that it can run in non-blocking mode. with
the block mode proc in place the driver knows that it should be
non-blocking and is able to tell this to the OS as well. The
call to the OS still happens, but is not blocking anymore, and
so the problem is gone.
A number of incompat changes in the Tcl IO core to work around
this problem in Expect will be removed now.
2004-06-03 Andreas Kupries <[email protected]>
* aclocal.m4 (TCLHDIRDASHI): Extended with path to unix headers as
well.
* expect_tcl.h: Added inclusion of <stdio.h>.
Both changes required for Expect to compile against Tcl 8.5
after the header reform.
* configure: Regenerated.
2004-05-19 Andreas Kupries <[email protected]>
* Merged changes from the official version 5.41 of expect into the
SF sources. See details below.
--------------------
Simon Taylor <[email protected]> provided fix for interact
-o which was completely broken by 5.40.1.
Added scroll support to official tkterm. Copied all fixes
from/to term_expect to/from tkterm.
Kiran Madabhushi <[email protected]> encountered interact
diagnostics incorrectly pointing to expect_background. Also,
found multiple -o flags behaving unexpectedly. Added diag.
Kristoffer Eriksson <[email protected]> noted typo in SIMPLE code in
exp_inter.c. However, this is extremely unlikely to affect any
machines.
Reinhard Max <[email protected]> noted that "make test" failed when
run in the background. The log testcase was testing the
send_tty command. Added code in both Expect and in the test to
handle this.
--------------------
2004-02-25 Andreas Kupries <[email protected]>
* Merged changes from the official version 5.40 of expect into the
SF sources. See details below. Partially already done (Rich
Kennedy's patch).
--------------------
Eric Raymond <[email protected]> provided troff-related
fixes for the expect, lib, and dislocate man pages.
Rich Kennedy <[email protected]> noted a bug having to do
with our caching of whether we have registered a filehandler.
This broke when Tcl was setting a handler on the same file.
Ken Pizzini <[email protected]> provided patch for
leak in spawn error handling.
Pete Lancashire <[email protected]> noted autopasswd
example broke on Solaris which capitalized prompts.
--------------------
2003-10-20 Andreas Kupries <[email protected]>
* exp_event.c (exp_get_next_event): Applied a patch made by Don
Libes in response to a bug report posted to news:comp.lang.tcl
by Rich Kennedy <[email protected]>. Patch was posted to c.l.t
too.

* Merged changes from the official version 5.39 of expect into the
SF sources. See details below. Partially already done.
--------------------
Poorva Gupta <[email protected]> noted that grantpt/unlockpt
order was backward. Strange that this was never a prob before!
Eric Raymond <[email protected]> provided a troff-related
fix for the multixterm man page.
Nicolas Roeser <[email protected]> noted confusion with md5 so I
made the Expect page more explicit about which file that hash
was based on.
Josh Purinton noted that earlier fix wasn't quite right. Exit
on INT/TERM should cause Expect to exit with signal embedded in
status. He also requested I obfuscate email addresses in this
file.
Guido Ostkamp <[email protected]> and Igor Sobrado
<[email protected]> noted that fixline1
rewrote scripts to be expect scripts even if they were expectk
scripts.
Dirk Petera <[email protected]> noted that any_spawn_id used
to work but did no longer. Looks like a bug left over from the
the I18L conversion. Fixed.
Steve Szabo noted exp_log_file -open channel failed. Fixed.
Fixed bug from 5.31 that prevent stty from returning messages
from underlying program.
Thomas Dickey <[email protected]> noted that ncurses
ignores 2-char term names because of, well, poor assumptions and
coding. Changed tkterm to use longer names.
Heath Moore <[email protected]> noted that exp_clib could lock
up if remtime happened to be precisely 0. Recoded to avoid.
At request of Per Otterholm <[email protected]>, wrote script
to read from stdin and echo passwords (exercise 9 in Tk chapter
of Expect book). Added to example directory as passwdprompt.
Josh Purinton <[email protected]> pointed out that by default,
SIGINT/TERM should cause expect's return status to be 1, not 0.
Paul Reithmuller <[email protected]> noted that
unbuffer shouldn't postprocess its output. Added stty_init.
Mordechai T. Abzug <[email protected]> noted that
log_file wasn't recording -append status.
James Kelly <[email protected]> noted weather example
needed new source.
Dimitar Haralanov <[email protected]> noted that interact
dumped core with interact { timeout 1 }
--------------------

2003-02-17 Andreas Kupries <[email protected]>
* Makefile.in:
* configure.in: Removed the check of configure against
configure.in and Makefile.in. It is a hassle to deal with when
trying to build straight from CVS, making unsupervised automatic
builds difficult

* configure.in: Made expect aware of tcl stubs. Derived from the
* exp_command.h: patches to expect done by Steve Landers
* exp_command.c: <[email protected]>. Modifications:
* exp_main_sub.c No global cmdinfo structures for 'close' and
* exp_main_exp.c: 'return'. Made this per-interpreter information
* exp_main_tk.c: as it should be. Using interp assoc data for this.
NOTE: stubs is not default, but has to be activated via '--enable-stubs'.
* configure: Regenerated.

* exp_chan.c (exp_close_all): Save the nextPtr in a local variable
before calling 'exp_close' as 'expStateFree' can be called from
it under some circumstances, possibly causing the memory
allocator to smash the value in 'esPtr'.

* exp_log.c (expLogChannelOpen): Fixed the bug reported on
comp.lang.tcl by Mordechai T. Abzug
<[email protected]>. The bugfix itself was provided
by Don Libes.

* exp_command.c (Exp_SpawnCmd): Tcl_GetChannelHandle expected a
ClientData*, but got an int*. sizeof(int) != sizeof(ClientData)
on 64bit platforms. Crashed the command on a PA-RISC 2.0 machine
with --enable-64bit set. Fix: Use temp. variables of type
ClientData to retrieve the fd's, and copy this into the actual
variables, with a cast to int.

* configure: regen'ed
* configure.in: use tcl_libdir in EXP_LIB_SPEC instead of
${INSTALL_ROOT}${exec_prefix}/lib (steffen)
* exp_main_tk.c (Tk_Init2): don't call XSynchronize on OS X.

* Merged changes from the official version 5.38 of expect into the
SF sources. See details below.
* Makefile.in: Added generation of MD5 checksum for distributed
archive.
* rftp: Bugfix by Curt Schroeder, see HISTORY
* HISTORY: Updated with new info.
* configure: Updated version info.
* configure.in: Updated version info.

* example/weather: Updated script to use rainmaker.wunderground.com
instead of cirrus.sprl.umich.edu. The old service is closed.
Added Larry Virden's notes about how rainmaker needs reverse DNS
from the peer making the connection or no data can retrieved.
This appears to be a blind error condition.

* exp_main_tk.c: #ifdef'd definition of "matherr". This hack is
not required for 8.4 anymore. But still for 8.3.

* exp_main_sub.c: Fixed typo in merge of #459646. Thanks to Hemang Lavana.
* exp_log.c (expStdoutLogU): Merged fix for SF Bug #513382 into
the HEAD (The source of the patch is "expect-sf418892-sf439042-branch").
Use Tcl_WriteChars/Tcl_Flush instead of 'fwrite' for tcl 8.1 and
beyond to enforce correct conversion of the internal UTF/8 into
the external representation.
* Merged fix for SF Bug #459646 into the HEAD (The source of the
patch is "expect-sf418892-sf439042-branch").
