Possibly contentious: The first time s.next() yields StopIteration (for
a given map argument s) is the last time map() *tries* s.next(). That
is, if other sequence args are longer, s will never again contribute
anything but None values to the result, even if trying s.next() again
could yield another result. This is the same behavior map() used to have
wrt IndexError, so it's the only way to be wholly backward-compatible.
I'm not a fan of letting StopIteration mean "try again later" anyway.
to no longer insist that len(seq) be defined.

This is meant to be a model for how other functions of this ilk (max,
filter, etc) can be generalized similarly. Feel encouraged to grab your
favorite and convert it!
Note some cute consequences:
list(file) == file.readlines() == list(file.xreadlines())
list(dict) == dict.keys()
list(dict.iteritems()) = dict.items()
list(xrange(i, j, k)) == range(i, j, k)
must now initialize the extra field used by the weak-ref machinery to
NULL themselves, to avoid having to require PyObject_INIT() to check
if the type supports weak references and do it there. This causes less
work to be done for all objects (the type object does not need to be
consulted to check for the Py_TPFLAGS_HAVE_WEAKREFS bit).
SF patch #103683: Alternative dll version resources.
Changes similar to the patch. MarkH should review.
File version and Product version text strings now 2.1a2.
64-bit file and product version numbers are now
PY_MAJOR_VERSION, PY_MINOR_VERSION, messy, PYTHON_API_VERSION
where
messy = PY_MICRO_VERSION*1000 + PY_RELEASE_LEVEL*10 + PY_RELEASE_SERIAL
Updated company name to "Digital Creations 2".
Copyright now lists Guido; "C in a circle" symbol used instead of (C).
Comments added so this is less likely to get flubbed again, and
#if/#error guys added to trigger if the version number manipulations
above overflow.
Add note about _symtable.
Add note that 'from ... import *' restriction may go away -- and move
the whole entry closer to the top, because it might bite people.
internal states. Put the old .seed() (which could only get at about
the square root of the # of possibilities) under the new name .whseed(),
for bit-level compatibility with older versions. This occurred to me
while reviewing effbot's book (he found himself stumbling over .seed()
more than once there ...).
- All constructors grow an optional argument `factory' which is a
callable used when new message instances are created by the next()
methods. Defaults to the rfc822.Message class.
- A new subclass of UnixMailbox is added, called PortableUnixMailbox.
It's identical to UnixMailbox, but uses a more portable test for
From_ delimiter lines. With PortableUnixMailbox, any line that
starts with "From " is considered a delimiter (this should really
check for two newlines before the F, but it doesn't.
SF patch http://sourceforge.net/patch/?func=detailpatch&patch_id=103453&group_id=5470
PyMember_Set of T_CHAR always raises exception.
Unfortunately, this is a use of a C API function that Python itself never makes, so
there's no .py test I can check in to verify this stays fixed. But the fault in the
code is obvious, and Dave Cole's patch just as obviously fixes it.
got broken). Also added new method .jumpahead(N). This finally gives us
a semi-decent answer to how Python's RNGs can be used safely and efficiently
in multithreaded programs (although it requires the user to use the new
machinery!).
functionality of, whrandom.py. Also closes all the "XXX" todos in
random.py. New frequently-requested functions/methods getstate() and
setstate(). All exported functions are now bound methods of a hidden
instance. Killed all unintended exports. Updated the docs.
FRED: The more I fiddle the docs, the less I understand the exact
intended use of the \var, \code, \method tags. Please review critically.
GUIDO: See email. I updated NEWS as if whrandom were deprecated; I
think it should be.
ctime, gmtime and localtime optional, defaulting to 'the current time' in
all cases. Adjust docs, add news item. Also convert all argument-handling to
METH_VARARGS. Closes SF patch #103265.
- Changed description of rich comparisons to emphasize that < and >
(etc.) are each other's reflection. Also use this word in the note
about the demise of __rcmp__.
except that it always returns Unicode objects.
A new C API PyObject_Unicode() is also provided.

Christmas present to myself: the bisect module didn't define what
happened if the new element was already in the list. It so happens
that it inserted the new element "to the right" of all equal elements.
Since it wasn't defined, among other bad implications it was a mystery
how to use bisect to determine whether an element was already in the
list (I've seen code that *assumed* "to the right" without justification).
Added new methods bisect_left and insort_left that insert "to the left"
instead; made the old names bisect and insort aliases for the new names
bisect_right and insort_right; beefed up docstrings to explain what
these actually do; and added a std test for the bisect module.
delimiter, watch out for backslash escaped delimiters. Also use =
instead of eq for character comparison (because a character is = to
it's integer value, but not eq to it).
In the limits.h comment, noted that INT_MAX and LONG_MAX are guaranteed
to be defined.
Noted that Reliant UNIX now gets proper API support for extension modules.
reverse() didn't work at all due to bad arg check.
Fixed that.
Added Brad Chapman to ACKS file, as the proud new owner of two
implicitly copyrighted lines of Python source code <wink>.
Repaired buffer_info's total lack of arg-checking.
Replaced memmove by memcpy in reverse() guts, as memmove is
often slower and the memory areas are guaranteed disjoint.
Replaced poke-and-hope unchecked decl of tmp buffer size by
assert-checked larger tmp buffer.
Got rid of inconsistent spaces before open paren in docstrings.
Added reverse() sanity tests to test_array.py.
XXX notes for now.
I could use help here!!!! Please mail me patches ASAP. We may have
to put some of this off to 2.0final, but it's best to have it in shape
now...
the Python Unicode implementation.
The internal buffer used for implementing the buffer protocol
is renamed to defenc to make this change visible. It now holds the
default encoded version of the Unicode object and is calculated
on demand (NULL otherwise).
Since the default encoding defaults to ASCII, this will mean that
Unicode objects which hold non-ASCII characters will no longer
work on C APIs using the "s" or "t" parser markers. C APIs must now
explicitly provide Unicode support via the "u", "U" or "es"/"es#"
parser markers in order to work with non-ASCII Unicode strings.
(Note: this patch will also have to be applied to the 1.6 branch
of the CVS tree.)
Montanaro, handle execution of indented regions by inserting an "if
1:" in front of the block. This better preserves things like triple
quoted strings and commented regions. This patch resolves PR#264.
1.5.2 was released, except those who contributed only to Doc files --
Fred has his own way of doing this.
This doesn't mean that I've got everyone who contributed *before*
1.5.2 was released in here... :-(
executive summary:
Instead of typing 'apply(f, args, kwargs)' you can type 'f(*arg, **kwargs)'.
Some file-by-file details follow.
Grammar/Grammar:
simplify varargslist, replacing '*' '*' with '**'
add * & ** options to arglist
Include/opcode.h & Lib/dis.py:
define three new opcodes
CALL_FUNCTION_VAR
CALL_FUNCTION_KW
CALL_FUNCTION_VAR_KW
Python/ceval.c:
extend TypeError "keyword parameter redefined" message to include
the name of the offending keyword
reindent CALL_FUNCTION using four spaces
add handling of sequences and dictionaries using extend calls
fix function import_from to use PyErr_Format
The attached patch set includes a workaround to get Python with
Unicode compile on BSDI 4.x (courtesy Thomas Wouters; the cause
is a bug in the BSDI wchar.h header file) and Python interfaces
for the MBCS codec donated by Mark Hammond.
Also included are some minor corrections w/r to the docs of
the new "es" and "es#" parser markers (use PyMem_Free() instead
of free(); thanks to Mark Hammond for finding these).
The unicodedata tests are now in a separate file
(test_unicodedata.py) to avoid problems if the module cannot
be found.
Attached you find the latest update of the Unicode implementation.
The patch is against the current CVS version.
It includes the fix I posted yesterday for the core dump problem
in codecs.c (was introduced by my previous patch set -- sorry),
adds more tests for the codecs and two new parser markers
"es" and "es#".
Attached you find an update of the Unicode implementation.
The patch is against the current CVS version. I would appreciate
if someone with CVS checkin permissions could check the changes
in.
The patch contains all bugs and patches sent this week and also
fixes a leak in the codecs code and a bug in the free list code
for Unicode objects (which only shows up when compiling Python
with Py_DEBUG; thanks to MarkH for spotting this one).
(python): Set defgroup :prefix to "py-" to make variable names cleaner.
(py-jpython-command, py-jpython-command-args): Set :tag for proper
capitalization of JPython in variable name display.
first time a py buffer is visited during the Emacs session. This
ensures that py-which-shells is initialized and also guarantees that
the mode lines reflect the correct shell. First bug found by GvR,
second one has long bugged :) me.
(py-toggle-shells): Programmatically, arg can also take the symbols
`cpython' or `jpython', which makes it easy to call with the value of
py-default-interpreter.
(py-shell): Don't need to initialize py-which-* variables since these
will guarantee to be initialized by python-mode when the first py
buffer is visited.
(py-default-interpreter): Update docstring.
casing when py-honor-comment-indentation is nil, but this could be a
religious issue with some. Seems to me we should still be dedenting
such comment lines one level.
buffer-syntactic-context -- just short circuit the TQS test by jumping
to point-min and doing the test from there. For long files, this will
be faster than looping with a re-search-backwards.
I don't know what its origins are but I think I've seen it
once in a NeXT dictionary application -- not sure whether
anyone owns copyright but I don't see why we should risk it.
py-newline-and-indent. These ought to get picked up by the mapcar
that follows; any existing binding to newline-and-indent gets shadowed
to py-newline-and-indent.
This will break some people who, e.g. bind C-m or C-j to newline but
still want these bound to py-newline-and-indent in Python mode. On
the other hand, the forced binding pisses off Emacs diehards. So
consider this experimental and see if any tall Dutch guys complain :-)
standard narrow-to-defun but works with Python classes and methods.
With no arg, narrows to most enclosing def/method. With C-u arg,
narrows to most enclosing class.
string we find ourselves in, based on the passed in delimiter.
(py-compute-indentation): Fixes for indentation errors when we land
inside a triple quoted string. For example:
def foo():
if os.path.isfile(o_pri_mbox_file) and os.path.isfile(o_pub_mbox_file):
print """\
I found both a private and a public mbox archive file
private: %s
public : %s
I won't move either file, but you should choose one and move it to
%s
You may want to merge them manually, but be careful about exposing private
correspondences to the public.""" % (
o_pri_mbox_file, o_pub_mbox_file, mbox_file)
*----indentation would be wrong on this line.
#simple things. First step: rename the Imenu supportive variables and
#functions in this file to py-imenu-* so I can grok what is part of
#python-mode and what is part of Imenu.
(py-imenu-create-index-engine): Fixed problem with two classes in a
single file, caused by new semantics of py-beginning-of-def-or-class
when called programmatically.
#Note, there are still some problems with Imenu when arguments to
#functions are funky, but it should be much better now.
string in the argument to execfile() so a Windows temp directory
named, e.g. c:\\tmp doesn't get interpreted as a file name with an
embedded tab! (given by C. Waldman).
this string should not end with whitespace.
(py-compute-indentation): Append whitespace regexp to
py-block-comment-prefix so that any combination of intervening
whitespace will be recognized.
change error messages to be a little more straightforward
change definition of FULL_PATH so that an error is raised if the
setuid wrapper is used un-edited
shell buffers.
(py-shell): Moved the require of comint to the top level. Also
use-local-map py-shell-map instead of hacking on the comint-mode-map.
This eliminates breakage of other comint-mode buffers (e.g. shell).
interactions with newer Emacsen, I've rewritten the way all the
process filters work in the *Python* buffer. We use more of the
comint infrastructure, specifically the default process filter. This
means that scrolling is now handled by the default comint variables
including comint-scroll-to-bottom-on-output. Note that this is
somewhat experimental change!
(py-comint-output-filter-function): Moved to here from the obsolete
py-process-filter function, the logic to pop and exec the next queued
file waiting to be executed.
(py-execute-file): Don't bind comint-scroll-to-bottom-on-output to t,
and save the excursion when inserting the "working on" message. This
lets the standard comint scrolling variables as set by the user,
continue to work.
(python-mode, py-shell, py-describe-mode): Remove description of
py-scroll-process-buffer. Also in py-shell, make
comint-output-filter-functions buffer-local, and add
py-comint-output-filter-function to this hook (instead of setting the
process filter).
(py-scroll-process-buffer): Deleted this variable. See comint
variables including comint-scroll-to-bottom-on-output.
(py-execute-region): When exec files are being queued, push the next
temp file on the end of the list.
(py-submit-bug-report): Removed reporting of py-scroll-process-buffer.
"3.67 fixes Imenu as far as classes are concerned, but some default
values for function arguments are still not supported."
This ought to fix that problem.
indetnation of normal statements: The regular expression that searches
for indenting comment lines has been changed to not require a
space/tab after the first `#'. We then explicitly look for
py-block-comment-prefix depending on the value of
py-honor-comment-indentation.
I think this more accurately reflects the documentation for
py-honor-comment-indentation.
conformations, etc., etc. inspired and given by Michael Ernst. These
include error string fixes, moving of comments to docstrings, some
other non-related typos, terminology standardizing (b/w TP and myself,
and b/w myself and myself :-) although more can still be done.
E.g. "outdenting" => "dedenting".
serial number isn't enough to uniquify the temp file name -- what if
two users are on the same machine? Add in the (emacs-pid) to help
further. Should never be tickled on Emacs 20, XEmacs 20, 21.
py-mark-def-or-class): Integrated Michael Ernst latest patches.
Primarily, it allows functions that search or mark defs/classes based
on programmatic specification, to take an 'either flag value which
allows searching for both classes and defs (stopping at the nearest
construct).
Also clean up some docstrings.
comment-indent-function's default lambda value (in simple.el), this
version finally kills this nit: auto-filling a comment that starts in
column zero with filladapt turned off would cascade the #'s to the
right.
Now auto-filling seems to work with or without filladapt, and with the
comment starting in any column.
(python-mode): Set comment-indent-function.
(py-execute-import-or-reload): Cool new command that imports or
reloads the current file as a module, so as not to clutter the global
namespace. Bound to C-c C-m.
(py-execute-def-or-class): New command that sends the current def or
class to the interpreter. Bound to C-M-x.
(py-execute-string): New command that sends arbitrary string to the
interpreter. Not bound by default.
(py-describe-mode): Doco updates.
py-beginning-of-def-or-class, and defaliased for backwards
compatibility. ME patch to add optional second argument, count.
(end-of-python-def-or-class): Renamed to py-end-of-def-or-class, and
defaliased for backwards compatibility. ME patch to add optional
second argument, count.
(py-shell): Recognize the Python debugger prompt
(py-jump-to-exception): Force into python-mode any buffer that gets
jumped to on exception. Cope with py-exception-buffer possibly a
cons.
