longobject.c _PyLong_AsByteArray: The original code had a gross bug:
the most-significant Python digit doesn't necessarily have SHIFT
significant bits, and you really need to count how many copies of the sign
bit it has else spurious overflow errors result.

sides of, all relevant power-of-2 boundaries, both positive and negative.
NEWS: Added brief dict news while I was at it.
native mode, and only when config #defines HAVE_LONG_LONG. Standard mode
will eventually treat them as 8-byte ints across all platforms, but that
likely requires a new set of routines in longobject.c first (while
sizeof(long) >= 4 is guaranteed by C, there's nothing in C we can rely
on x-platform to hold 8 bytes of int, so we'll have to roll our own;
I'm thinking of a simple pair of conversion functions, Python long
to/from sized vector of unsigned bytes; that may be useful for GMP
conversions too; std q/Q would call them with size fixed at 8).
test_struct.py: In addition to adding some native-mode 'q' and 'Q' tests,
got rid of unused code, and repaired a non-portable assumption about
native sizeof(short) (it isn't 2 on some Cray boxes).
libstruct.tex: In addition to adding a bit of 'q'/'Q' docs (more needed
later), removed an erroneous footnote about 'I' behavior.
Armin Rigo pointed out that the way the line-# table got built didn't work
for lines generating more than 255 bytes of bytecode. Fixed as he
suggested, plus corresponding changes to pyassem.py, plus added some
long overdue docs about this subtle table to compile.c.

it in without further ado.
instead of multiplication to generate the probe sequence. The idea is
recorded in Python-Dev for Dec 2000, but that version is prone to rare
infinite loops.
The value is in getting *all* the bits of the hash code to participate;
and, e.g., this speeds up querying every key in a dict with keys
[i << 16 for i in range(20000)] by a factor of 500. Should be equally
valuable in any bad case where the high-order hash bits were getting
ignored.
Also wrote up some of the motivations behind Python's ever-more-subtle
hash table strategy.

elements when crunching a list, dict or tuple. Now takes linear time
instead -- huge speedup for even moderately large containers, and the
code is notably simpler too.
Added some basic "is the output correct?" tests to test_pprint.
The comment following used to say:
/* We use ~hash instead of hash, as degenerate hash functions, such
as for ints <sigh>, can have lots of leading zeros. It's not
really a performance risk, but better safe than sorry.
12-Dec-00 tim: so ~hash produces lots of leading ones instead --
what's the gain? */
That is, there was never a good reason for doing it. And to the contrary,
as explained on Python-Dev last December, it tended to make the *sum*
(i + incr) & mask (which is the first table index examined in case of
collison) the same "too often" across distinct hashes.
Changing to the simpler "i = hash & mask" reduced the number of string-dict
collisions (== # number of times we go around the lookup for-loop) from about
6 million to 5 million during a full run of the test suite (these are
approximate because the test suite does some random stuff from run to run).
The number of collisions in non-string dicts also decreased, but not as
dramatically.
Note that this may, for a given dict, change the order (wrt previous
releases) of entries exposed by .keys(), .values() and .items(). A number
of std tests suffered bogus failures as a result. For dicts keyed by
small ints, or (less so) by characters, the order is much more likely to be
in increasing order of key now; e.g.,
>>> d = {}
>>> for i in range(10):
... d[i] = i
...
>>> d
{0: 0, 1: 1, 2: 2, 3: 3, 4: 4, 5: 5, 6: 6, 7: 7, 8: 8, 9: 9}
>>>
Unfortunately. people may latch on to that in small examples and draw a
bogus conclusion.
test_support.py
Moved test_extcall's sortdict() into test_support, made it stronger,
and imported sortdict into other std tests that needed it.
test_unicode.py
Excluced cp875 from the "roundtrip over range(128)" test, because
cp875 doesn't have a well-defined inverse for unicode("?", "cp875").
See Python-Dev for excruciating details.
Cookie.py
Chaged various output functions to sort dicts before building
strings from them.
test_extcall
Fiddled the expected-result file. This remains sensitive to native
dict ordering, because, e.g., if there are multiple errors in a
keyword-arg dict (and test_extcall sets up many cases like that), the
specific error Python complains about first depends on native dict
ordering.
Allow module getattr and setattr to exploit string interning, via the
previously null module object tp_getattro and tp_setattro slots. Yields
a very nice speedup for things like random.random and os.path etc.
Fixed a half dozen ways in which general dict comparison could crash
Python (even cause Win98SE to reboot) in the presence of kay and/or
value comparison routines that mutate the dict during dict comparison.
Bugfix candidate.
d1 == d2 and d1 != d2 now work even if the keys and values in d1 and d2
don't support comparisons other than ==, and testing dicts for equality
is faster now (especially when inequality obtains).
NEEDS DOC CHANGES.
More AttributeErrors transmuted into TypeErrors, in test_b2.py, and,
again, this strikes me as a good thing.
This checkin completes the iterator generalization work that obviously
needed to be done. Can anyone think of others that should be changed?
NEEDS DOC CHANGES
A few more AttributeErrors turned into TypeErrors, but in test_contains
this time.
The full story for instance objects is pretty much unexplainable, because
instance_contains() tries its own flavor of iteration-based containment
testing first, and PySequence_Contains doesn't get a chance at it unless
instance_contains() blows up. A consequence is that
some_complex_number in some_instance
dies with a TypeError unless some_instance.__class__ defines __iter__ but
does not define __getitem__.
to string.join(), so that when the latter figures out in midstream that
it really needs unicode.join() instead, unicode.join() can actually get
all the sequence elements (i.e., there's no guarantee that the sequence
passed to string.join() can be iterated over *again* by unicode.join(),
so string.join() must not pass on the original sequence object anymore).
because PySequence_Fast() started working for free as soon as
PySequence_Tuple() learned how to work with iterators. For some reason
unicode.join() still doesn't work, though.
NEEDS DOC CHANGES.
This one surprised me! While I expected tuple() to be a no-brainer, turns
out it's actually dripping with consequences:
1. It will *allow* the popular PySequence_Fast() to work with any iterable
object (code for that not yet checked in, but should be trivial).
2. It caused two std tests to fail. This because some places used
PyTuple_Sequence() (the C spelling of tuple()) as an indirect way to test
whether something *is* a sequence. But tuple() code only looked for the
existence of sq->item to determine that, and e.g. an instance passed
that test whether or not it supported the other operations tuple()
needed (e.g., __len__). So some things the tests *expected* to fail
with an AttributeError now fail with a TypeError instead. This looks
like an improvement to me; e.g., test_coercion used to produce 559
TypeErrors and 2 AttributeErrors, and now they're all TypeErrors. The
error details are more informative too, because the places calling this
were *looking* for TypeErrors in order to replace the generic tuple()
"not a sequence" msg with their own more specific text, and
AttributeErrors snuck by that.
NEEDS DOC CHANGES.
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.
NEEDS DOC CHANGES.
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).

the square root of the # of possibilities) under the new name .whseed(),

more than once there ...).
- All constructors grow an optional argument `factory' which is a

- 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.

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

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).

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 :-)

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.

"3.67 fixes Imenu as far as classes are concerned, but some default

This ought to fix that problem.

I think this more accurately reflects the documentation for

comment-indent-function's default lambda value (in simple.el), this

Now auto-filling seems to work with or without filladapt, and with the
comment starting in any column.

lack a LFD (leaving users to the more obscure C-j), I think it makes
better sense to add this default binding.
is based on the line above, watch out for landing inside a triple
quoted string. In this case, use iterative search +
parse-partial-sexp backwards to find the beginning of the string.
Note this does affect performance, but very little in the common cases
(I hope). It could be made *much* faster by adding Emacs and XEmacs
dependent code -- different code naturally. :-(

file local variable section of a file. When set, and the user hits
C-c C-c, this file gets executed instead of the buffer's file. Idea
given by Roy Dragseth <royd@math.uit.no>, but implemented differently.
(py-execute-buffer): Support py-master-file variable. If this names a
relative path, default-directory is prepended via expand-file-name.
(python-mode): Conditionalize imenu initializations to when we can
safely require imenu. Under Emacs this should prevent python-mode
from hosing the global value of imenu-create-index-function and
messing things up for all other modes. Problem identified by
Christian Egli.
(py-describe-mode): py-delete-char => py-electric-backspace. Given by
Christian Egli.
(imenu-example--create-python-index-engine): Use
buffer-substring-no-properties. Also, don't use
imenu-create-submenu-name. Apparently it is obsolete.
These Imenu patches were given by Christian Egli
<christian.egli@stest.ch>
py-keep-region-active so that the marked def/class gets the
zmacs-region or transient-mark region highlighted. Also point should
be left at the end of the marked region.
(py-mode-map): Moved py-mark-def-or-class to M-C-h to conform to Emacs
major mode standards.
to the Web site.
(py-defun-start-re, py-class-start-re): Changed to defconst.
(py-traceback-line-re): Regular expression describing what traceback
lines look like.
(py-point): New defsubst copied from CC Mode.
(py-highlight-line): Function which does the work of making a
traceback line mouseable. This only works on XEmacs. Someone familar
with Emacs text properties and such will have to do that port.
(py-mode-map): Added C-c- bound to py-up-exception and C-c= bound to
py-down-exception. Also, more concise form for mapcar.
(py-mode-output-map): New keymap for the *Python Output* buffer which
only has keybindings for py-mouseto-exception and py-goto-exception.
All other self-insert-command's are bound to beep. This is actually
bogus because the buffer should really be made read-only and the
functions that insert in that buffer should bind inhibit-read-only.
Also, this map should be bound to highlighted extents in a *Python*
shell buffer, but this stuff hasn't been migrated into there.
(py-postprocess-output-buffer): New function which extentifies the
*Python Output* buffer. The bogosities are that this only runs when
the synchronous process in the buffer is finished (so it doesn't work
for async procs), and it should also be merged into py-process-filter
so the *Python* shell gets mouseable too.
(py-shell): Added C-c- and C-c= to the comint buffer's keymap. The
bogosity is that py-goto-exception should also be bound, but it cannot
be bound to C-cC-c (since that interferes with
comint-interrupt-subjob's typical binding). Also, traceback lines
aren't mouseable in this buffer.
(py-execute-region): Support for traceback jumping. This really is
quite a kludge, but necessary based on the way all this stuff works.
There's bound to be broken interactions here.
(py-jump-to-exception, py-mouseto-exception, py-goto-exception,
py-find-next-exception, py-down-exception, py-up-exception): All new
commands and functions to implement traceback jumping.
(py-compute-indentation): Hope this change doesn't get lost in all the
noise above!!!! This fixes broken non-indentation of a line when TAB
is hit inside a string that isn't a multi-line string.

nonsense.py file that flexes all the font-lock keyword combinations.

(py-serial-number): New variable.
(py-execute-region): If make-temp-name is broken, simply append a
serial number to the string "python-" to get a temporary file name.
It's possible concurrent NTEmacs can step on each others toes, but it
makes no sense to further coddle a busted NTEmacs.
(py-mode-map): Moved py-mark-def-or-class from M-C-h to C-c C-m since
the old binding conflicts with the standard global backward-kill-word
binding, and this new binding is more conformant with other language
modes. Moved py-mark-block to C-c C-k.
(py-electric-backspace, py-electric-delete): Support the XEmacs 20 Way
for backspace and delete mappings. In XEmacs 19, Emacs 19, and Emacs
20, both backspace and delete keysyms are bound to
py-electric-backspace. In XEmacs 20, backspace and delete keysyms are
bound separately, allowing the user to specify forward or backward
deletion of the delete keysym through the variable
delete-key-deletes-forward. All this is the Right Way To Do It and
this implementation was largely ripped from CC Mode.
(py-execute-file): Better interaction with comint. Set
comint-scroll-to-bottom-on-output to t. Wrapper buffer change in
unwind-protect in case process filter fails.
(py-shell): Start Python with -i flag to fix tty problem on Windows;
presumably -- not yet tested.
(py-clear-queue): New function to clear the pending exec file queue.
Not currently keybound.
(py-execute-region, py-execute-buffer): Added optional async flag (use
via C-u prefix) to execute the region in a new asynchrous buffer, even
if the Python shell is running.
(py-append-to-process-buffer): Removed as obsolete. Comint provides
this functionality.
Removed fbound test defun of match-string. All modern X/Emacsen have
this function.
his *own* RCS file for python-mode.el, and I've agreed that it would
be better if his version was in the Python source tree. However I
don't want to totally get rid of the old RCS file (which has
interesting info such as which version was in which Python release).
So I've moved the old one to python-mode-old.el behind the scenes,
and this checkin message indicates that I'm now deleting it.
If you do an update, you will actually get Barry's *new* version!
Introductory comment updates.
(python-font-lock-keywords): Added "assert"
(py-block-closing-keywords-re): New variable.
(py-no-outdent-re): Rewrite to use py-block-closing-keywords-re.
(py-shell): py-process-filter should no longer be necessary. Comint
should do all the work. Note that more fixes to the py-shell process
mechanism need to be done.
(py-execute-region): Check for empty region. Some questionable
changes to set-buffer after shell-command-on-region. Again, this all
needs to be closely examined for X/Emacs 19/20 compatibility.
(py-goto-beyond-final-line): py-parse-partial-sexp-works-p should no
longer be necessary.
(py-statement-closes-block-p): Use py-block-closing-keywords-re.
Currently fairly minimal, but I'll be adding to this as needed. I
think it's pretty darn close.
To use this, just load the file and in a C buffer type:
M-x c-set-style RET python RET
[there are ways to automate much of this!]
defeat extra outdentation for block closing statements (return, raise,
break, continue, pass).
(py-compute-indentation): extra argument to honor block closing
statements.
(py-electric-colon, py-indent-region): use py-compute-indentation's
extra argument
(py-statement-closes-block-p): `pass' treated as a block closing
statement.
add-change-log-entry-other-window is so bad about guessing the proper
name of Python functions, methods and variables, so finally I wrote
the following (unidiff patch against python-mode.el 2.73):
Per Cederqvist <ceder@signum.se>
right thing.
(py-comment-region): let-bind comment-start to "## " so commented
regions get transformed into non-indenting comment lines.
(py-compute-region): Implement modification to rule for recognizing
"indenting comment lines".
py-outdent-left, py-mode-map): Folded all functionality into
py-shift-region-* commands. Bound C-c C-l to py-shift-region-left and
C-c C-r to py-shift-region-right. Removed py-indent-right and
py-indent-left.
py-submit-bug-report placed on C-c C-b, and py-version placed on C-c
C-v.
(py-version, py-submit-bug-report): new functions
(py-version, py-help-address): new variables
