* Do not release unallocated Tcl objects. Closes #117278 and #117167.Martin v. Löwis2000-10-291-3/+8

* Fix for Bug #116453.Guido van Rossum2000-10-121-6/+6
| | | | | | 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.
* [ Bug #113803 ] [2.0b1 NT4.0] printing non asci char causes idle to abortGuido van Rossum2000-10-061-44/+86
| | | | | | | | | | | | | | | 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.)

* Bunch of minor ANSIfications: 'void initfunc()' -> 'void initfunc(void)',Thomas Wouters2000-07-211-8/+6
| | | | | | | | | | | | | | | | | | 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 ;)

| | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* Patch from Michael Hudson to fix flatten recursive data structures:Andrew M. Kuchling2000-06-191-5/+8
| | | | | | | | | [mwh21@atrus build]$ ./python >>> import Tkinter >>> l = [] >>> l.append(l) >>> Tkinter._flatten(l) Segmentation fault (core dumped)
* Patch from /F:Andrew M. Kuchling2000-06-181-0/+100
| | | | | | | | | | 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.
* When the UTF-8 conversion to Unicode fails, return an 8-bit stringGuido van Rossum2000-05-041-1/+5
| | | | | | | | | | 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.)
* Two changes to improve (I hope) Unicode support.Guido van Rossum2000-05-041-2/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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?
* Vladimir Marangozov's long-awaited malloc restructuring.Guido van Rossum2000-05-031-4/+4
| | | | | | | | | | 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.)

* The Tcl_Obj patch discussed on the patches list.Guido van Rossum2000-03-291-82/+77
| | | | | | | 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).

| | | | | | | | | | | | | | | | | | | | 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.
* Fixed the EventHook() code so that it also works on Windows, sort of.Guido van Rossum1998-06-131-6/+26
| | | | | | | | | | | | | (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...)
* On Windows, need #include <windows.h>; and it's MS_WINDOWS, not MS_WIN32.Guido van Rossum1998-05-291-2/+6

* Changes to make it possible to write multi-threaded programs usingGuido van Rossum1998-05-281-152/+390
| | | | | | | | | | 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().
* Use a different implementation of EventHook(). The new versionGuido van Rossum1998-05-221-37/+74
| | | | | | | | | | 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 :-(

* Trivial little change: timer tokens shouldn't have a Print() function,Guido van Rossum1998-05-121-8/+7

* Still somewhat experimental speedup. This appears to speed up theGuido van Rossum1998-04-291-9/+110
| | | | | | | | | | | | | | 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.
