Makefile.in: run config.status in "make recheck". configure.in: add test for hypot(). config.h.in, configure: since configure.in changed. rest: the usual boring stuff.

|

|
||||
* Python/modsupport.c (initmodule2), Include/methodobject.h,
|
||||
Objects/methodobject.c: introduced METH_FREENAME bit passed to
|
||||
newmethodobject to indicate that if the object is freed the name
|
||||
pointer must also be freed (this saves a long standing memory leak
|
||||
in initmodule2)
|
||||
|
||||
* Modules/structmodule.c (struct_pack, struct_unpack): use memcpy
|
||||
instead of double precision assignment (since a string isn't
|
||||
always double-aligned, e.g. when debug fields are present in the
|
||||
object header)
|
||||
|
||||
* Objects/floatobject.c (float_hash): changed a constant to avoid
|
||||
float->long conversion overflow

|
||||
* Python/bltinmodule.c (builtin_pow): fix coerce() ref count
|
||||
nightmare (core dumps on Linux)
|
||||
|
||||
* Python/pythonrun.c: call flushline() in print_error(), after
|
||||
fetching the exception info, since flushline() can mask an
|
||||
exception; move flushline() calls around so they are not between
|

the detection and printing of the exception

The Tk extension
|
||||
----------------
|
||||
|
||||
Tk (the user interface component of John Ousterhout's Tcl language) is
|
||||
also usable from Python. Since this requires that you first build and
|
||||
install Tcl/Tk, the Tk interface is not enabled by default. It
|
||||
requires Tcl 7.3 and Tk 3.6. For more info about Tk, including
|
||||
pointers to the source, see John Ousterhout's home page at
|
||||
<URL:http://playground.sun.com/~ouster/>.
|
||||
|
||||
To enable the Python/Tk interface, once you've built and installed
|
||||
Tcl/Tk, all you need to do is edit two lines in Modules/Setup; search
|
||||
for the string "Tk". Un-comment one (normally the first) of the lines
|
||||
beginning with "#tkinter" and un-comment the line beginning with
|
||||
"#TKPATH". (If you have installed Tcl/Tk in unusual places you will
|
||||
have to edit the first line as well to fix the -I and -L options.)
|
||||
See the Build Instructions above for more details.
|
||||
|
||||
There is little documentation. Begin with fetching the "Tk Lifesaver"
|
||||
document, e.g. <URL:ftp://ftp.cwi.nl/pub/python/tkinter-doc.tar.gz> (a
|
||||
gzipped tar file containing a PostScript file). There are demos in
|
||||
the Demo/tkinter directory, in the subdirectories guido, matt and www.
|
||||
|
||||
Note that there's a Python module called "Tkinter" (capital T) which
|
||||
lives in Lib/tkinter/Tkinter.py, and a C module called "tkinter"
|
||||
(lower case t) which lives in Modules/tkintermodule.c. Demos and
|
||||
normal Tk applications only import the Python Tkinter module -- only
|
||||
the latter uses the C tkinter module directly. In order to find the C
|
||||
tkinter module, it must be compiled and linked into the Python
|
||||
interpreter -- the tkinter line in the Setup file does this. In order
|
||||
to find the Python Tkinter module, sys.path must be set correctly --
|
||||
the TKPATH assignment in the Setup file takes care of this, but only
|
||||
if you install Python properly ("make install libinstall"). (You can
|
||||
also use dynamic loading for the C tkinter module, in which case you
|
||||
must manually fix up sys.path or set $PYTHONPATH for the Python
|
||||
Tkinter module.)
