Jack Jansen 84c10b13bb File handlers don't work on the mac, so don't pretend they do. I guess this is a 2.1.1 candidate, if it isn't too late for that. 2001-07-16 19:32:52 +00:00

Martin v. Löwis 02956017f9 Do not release unallocated Tcl objects. Closes #117278 and #117167. 2000-10-29 00:44:43 +00:00
Guido van Rossum ada6d87c0c Fix for Bug #116453.
Direct use of interp->result is deprecated; changing this to
Tcl_GetStringResult(interp) everywhere fixed the problem of losing the
error message with TclError exceptions, on Windows.

Guido van Rossum 2834b974b6 [ Bug #113803 ] [2.0b1 NT4.0] printing non asci char causes idle to abort
http://sourceforge.net/bugs/?func=detailbug&bug_id=113803&group_id=5470

Add Unicode support and error handling to AsString().  Both AsString()
and Merge() now return NULL and set a proper Python exception
condition when an error happens; Merge() and other callers of
AsString() check for errors from AsString().  Also fixed cleanup in
Merge() and Tkapp_Call() return cleanup code; the fv array was not
necessarily completely initialized, causing calls to ckfree() with
garbage arguments!

(Also reindented some lines that were longer than 80 chars and
reformatted some code that used an alien coding standard.)

Thomas Wouters 58d0510245 ANSIfy some more forward declarations. 2000-07-24 14:43:35 +00:00
Thomas Wouters f3f33dcf03 Bunch of minor ANSIfications: 'void initfunc()' -> 'void initfunc(void)',
and a couple of functions that were missed in the previous batches. Not
terribly tested, but very carefully scrutinized, three times.

All these were found by the little findkrc.py that I posted to python-dev,
which means there might be more lurking. Cases such as this:

long
func(a, b)
	long a;
	long b; /* flagword */
{

and other cases where the last ; in the argument list isn't followed by a
newline and an opening curly bracket. Regexps to catch all are welcome, of
course ;)

Fred Drake a44d353e2b Trent Mick <trentm@activestate.com>:
The common technique for printing out a pointer has been to cast to a long
and use the "%lx" printf modifier. This is incorrect on Win64 where casting
to a long truncates the pointer. The "%p" formatter should be used instead.

The problem as stated by Tim:
> Unfortunately, the C committee refused to define what %p conversion "looks
> like" -- they explicitly allowed it to be implementation-defined. Older
> versions of Microsoft C even stuck a colon in the middle of the address (in
> the days of segment+offset addressing)!

The result is that the hex value of a pointer will maybe/maybe not have a 0x
prepended to it.


Notes on the patch:

There are two main classes of changes:
- in the various repr() functions that print out pointers
- debugging printf's in the various thread_*.h files (these are why the
patch is large)


Closes SourceForge patch #100505.

Andrew M. Kuchling 288e97b7fe Patch from Michael Hudson to fix flatten recursive data structures:
[mwh21@atrus build]$ ./python
>>> import Tkinter
>>> l = []
>>> l.append(l)
>>> Tkinter._flatten(l)
Segmentation fault (core dumped)
2000-06-19 00:55:09 +00:00
Andrew M. Kuchling e475e70128 Patch from /F:
this patch adds a fast _flatten function to the _tkinter
module, and imports it from Tkinter.py (if available).

this speeds up canvas operations like create_line and
create_polygon.  for example, a create_line with 5000
vertices runs about 50 times faster with this patch in
place.

Guido van Rossum 69529ad0cc When the UTF-8 conversion to Unicode fails, return an 8-bit string
instead.  This seems more robust than returning an Unicode string with
some unconverted charcters in it.

This still doesn't support getting truly binary data out of Tcl, since
we look for the trailing null byte; but the old (pre-Unicode) code did
this too, so apparently there's no need.  (Plus, I really don't feel
like finding out how Tcl deals with this in each version.)
2000-05-04 15:55:17 +00:00
Guido van Rossum 990f5c6c98 Two changes to improve (I hope) Unicode support.
1. In Tcl 8.2 and later, use Tcl_NewUnicodeObj() when passing a Python
Unicode object rather than going through UTF-8.  (This function
doesn't exist in Tcl 8.1, so there the original UTF-8 code is still
used; in Tcl 8.0 there is no support for Unicode.)  This assumes that
Tcl_UniChar is the same thing as Py_UNICODE; a run-time error is
issued if this is not the case.

2. In Tcl 8.1 and later (i.e., whenever Tcl supports Unicode), when a
string returned from Tcl contains bytes with the top bit set, we
assume it is encoded in UTF-8, and decode it into a Unicode string
object.

Notes:

- Passing Unicode strings to Tcl 8.0 does not do the right thing; this
isn't worth fixing.

- When passing an 8-bit string to Tcl 8.1 or later that has bytes with
the top bit set, Tcl tries to interpret it as UTF-8; it seems to fall
back on Latin-1 for non-UTF-8 bytes.  I'm not sure what to do about
this besides telling the user to disambiguate such strings by
converting them to Unicode (forcing the user to be explicit about the
encoding).

- Obviously it won't be possible to get binary data out of Tk this
way.  Do we need that ability?  How to do it?

Guido van Rossum b18618dab7 Vladimir Marangozov's long-awaited malloc restructuring.
For more comments, read the patches@python.org archives.
For documentation read the comments in mymalloc.h and objimpl.h.

(This is not exactly what Vladimir posted to the patches list; I've
made a few changes, and Vladimir sent me a fix in private email for a
problem that only occurs in debug mode.  I'm also holding back on his
change to main.c, which seems unnecessary to me.)

Guido van Rossum 64231e5c39 Add back an obscure "feature" to the Obj version of Tkapp_Call(): a
None in an argument list *terminates* the argument list: further
arguments are *ignored*.  This isn't kosher, but too much code relies
on it, implicitly.  For example, IDLE was pretty broken.

Guido van Rossum a1f0a8f4a4 Don't use the object call interface in Tk 8.0 -- the EvalObj* API
changed from 8.0 to 8.1 and I see no big reason to use objects in 8.0.
At least now it works again with all versions from 8.0 - 8.3.

Guido van Rossum 632de27021 The Tcl_Obj patch discussed on the patches list.
This was originally submitted by Martin von Loewis as part of his
Unicode patch; all I did was add special cases for Python int and
float objects and rearrange the object type tests somewhat to speed up
the common cases (string, int, float, tuple, unicode, object).
2000-03-29 00:19:50 +00:00
Guido van Rossum a80649b357 Patch by Neil Schemenauer to remove support for Tcl/Tk versions before
8.0.  There really is no excuse, and for who really still wants those,
they can go back to Python 1.5.2.

Guido van Rossum e187b0eb20 Add a call to Tcl_FindExecutable(). This was inspired by a patch by

Guido van Rossum 6b26a06037 Patch by Dieter Maurer to make things work for Tcl/Tk 8.1 (tested with
8.1.1).  His approach doesn't work with Tcl/Tk 8.2, so I've placed it
inside #if TKMAJORMINOR == 8001 and #endif.  See also his patch for
tkappinit.c.

Guido van Rossum 65d5b5763c Thanks to Chris Herborth, the thread primitives now have proper Py*

Guido van Rossum 41f0a98f8f Looks like I didn't test this interactively. The EventHook() code was
broken; it asked for the current thread state when there was none.
Fixed by using the saved event_tstate.
1998-10-12 16:26:22 +00:00
Guido van Rossum dc1adabcb8 Patch by Jonathan Giddy (with some cleanup by me) to always use the

handling function) rather than the thread state of the function that
created the client data structure.

1998-08-05 13:53:32 +00:00
Guido van Rossum 43ff8683fe Temporarily get rid of the registration of Tcl_Finalize() as a
low-level Python exit handler.  This can attempt to call Python code
at a point that the interpreter and thread state have already been
destroyed, causing a Bus Error.  Given the intended use of
Py_AtExit(), I'm not convinced that it's a good idea to call it
earlier during Python's finalization sequence...  (Although this is
the only use for it in the entire distribution.)

Guido van Rossum c821d1ecc0 Add a cast that a picky SGI compiler found was necessary. 1998-07-07 22:25:47 +00:00
Guido van Rossum f766e23f63 There was an error check in a loop in PythonCmd which called
PythonCmd_Error() but failed to return.  The error wasn't very likely
(only when we run out of memory) but since the check is there we might
as well return the error.  (I think that Barry introduced this buglet
when he added error checks everywhere.)

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).
1998-06-15 14:03:52 +00:00
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.
1998-06-15 04:36:09 +00:00
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 :-(
