Guido van Rossum 5e97783c8f # Note: a previous checkin message was lost because I can now use CVS
# from my PC at home, but it can't send email :-(

Add a clarifying comment about the new ENTER_OVERLAP and
LEAVE_OVERLAP_TCL macros; get rid of all the bogus tests for deleted
interpreters (Tcl already tests for this; they were left over from an
earlier misguided attempt to fix the threading).

Guido van Rossum 62320c9b9b # (My first checkin from Windows NT using remote CVS!)
There were some serious problem with the thread-safety code.
The basic problem was that often the result was gotten out of
the Tcl interpreter object after releasing the Tcl lock.
Of course, another thread might have changed the return value
already, and this was indeed happening.  (Amazing what trying
it on a different thread implementation does!)

The solution is to grab the Python lock without releasing the
Tcl lock, so it's safe to create a string object or set the
exceptions from the Tcl interpreter.  Once that's done, the
Tcl lock is released.

Note that it's now legal to acquire the Python lock while the
the Tcl lock is held; but the reverse is not true: the Python
lock must be released before the Tcl lock is acquired.  This
in order to avoid deadlines.  Fortunately, there don't seem to
be any problems with this.

Guido van Rossum ad4db17552 Fixed the EventHook() code so that it also works on Windows, sort of.
(The "sort of" is because it uses kbhit() to detect that the user
starts typing, and then no events are processed until they hit
return.)

Also fixed a nasty locking bug: EventHook() is called without the Tcl
lock set, so it can't use the ENTER_PYTHON and LEAVE_PYTHON macros,
which manipulate both the Python and the Tcl lock.  I now only acquire
and release the Python lock.

(Haven't tested this on Unix yet...)

Guido van Rossum 2a5119b680 On Windows, need #include <windows.h>; and it's MS_WINDOWS, not MS_WIN32. 1998-05-29 01:28:40 +00:00
Guido van Rossum 00d93066b0 Changes to make it possible to write multi-threaded programs using
Tkinter.  This adds a separate lock -- read the comments.  (This was
also needed for Mark Hammond's attempts to make PythonWin
Tkinter-friendly.)

The changes have affected the EventHook slightly, too; and I've done
some more cleanup of the code that deals with the different versions
of Tcl_CreateFileHandler().
1998-05-28 23:06:38 +00:00
Guido van Rossum 7bf15648a4 Use a different implementation of EventHook(). The new version
registers an input file handler for stdin with Tcl and handles Tcl
events until something is available on stdin; it then deletes the
handler and returns from EventHook().

This works with or without GNU readline, and doesn't busy-wait.

It still doesn't work for Mac or Windows :-(

Guido van Rossum 597ac20708 Trivial little change: timer tokens shouldn't have a Print() function,
they should have a Repr() function.
1998-05-12 14:36:19 +00:00
Guido van Rossum 212643f199 Still somewhat experimental speedup. This appears to speed up the
most common interface to Tcl, the call() method, by maybe 20-25%.

The speedup code avoids the construction of a Tcl command string from
the argument list -- the Tcl argument list is immediately parsed back
by Tcl_Eval() into a list that is *guaranteed* (by Tcl_Merge()) to be
exactly the same list, so instead we look up the command info and call
the command function directly.  If the lookup fails, we fall back to
the old method (Tcl_Merge() + Tcl_Eval()) so we don't need to worry
about special cases like undefined commands or the occasional command
("after") that sets the info.proc pointer to NULL -- let TclEval()
deal with these.

Guido van Rossum 9d1b7ae65b Add a new method of interpreter objects, interpaddr(). This returns
the address of the Tcl interpreter object, as an integer.  Not very
useful for the Python programmer, but this can be called by another C
extension that needs to make calls into the Tcl/Tk C API and needs to
get the address of the Tcl interpreter object.  A simple cast of the
return value to (Tcl_Interp *) will do the trick now.
1998-04-29 16:17:01 +00:00
Guido van Rossum 2ea1c94b9a On the Mac a call to TkMacInitMenus is needed. Also, we pass
appropriate events to Sioux so the console window remains functional.

Guido van Rossum 1c0d31565d Delete the 'exit' command from the Tcl interpreter -- it would allow
users to exit Python without the normal precautions.  (The can do this
using os._exit() anyway, but at least that's documented.)

Guido van Rossum 07e9fbf6b9 Register Tcl_Finalize as a Python exit handler. 1998-02-06 22:35:46 +00:00
Guido van Rossum a59406abdf Darn. When thread support is disabled, the BEGIN/END macros don't
save and restore the tstate, but explicitly calling
PyEval_SaveThread() does reset it!  While I think about how to fix
this for real, here's a fix that avoids getting a fatal error.

Guido van Rossum 54e2091ba2 Add an optional hack for threads in Tkinter.
This one works!  However it requires using a modified version of
tclNotify.c (provided), which requires access to the Tcl source
to compile it.  In order to enable this hack, add the following
to the Setup line for _tkinter:
   tclNotify.c -DHAVE_PYTCL_WAITUNTILEVENT -I$(TCL)/generic
where TCL points to the source tree of Tcl 8.0.  Other versions
of Tcl are not supported.

The tclNotify.c file is copyrighted by Sun Microsystems; the
licensing terms are in the file license.terms.  According to this
file, no further permission to distribute this is required,
provided the file license.terms is included.  Hence, I am checking
that in, too.

Guido van Rossum 0969d36275 New mechanism for GNU readline interface, via module 1997-08-05 21:27:50 +00:00
Guido van Rossum 35d43377b4 Functionality enhancement: allow other threads to use Tk commands
while one thread is blocked in mainloop().  Also, handle signals (not
just interrupts) as soon as they happen.

Cleanup: remove support for Tcl/Tk versions 7.4/4.0.  (I've confirmed
that it works for 7.5/4.1 and 7.6/4.2, as well as 8.0b2.)

Coding style change: instead of ``func (args)'', write ``func(args)''
everywhere.

Minor functionality change: use PyArg_ParseTuple everywhere.  This
should only affect the errors reported for bad argument lists; in
particular, deletefilehandler() is much clearer about what's going
on.

(XXX Still to do: Mac and Win ports to 8.0b2.)
