[issue3439] create a numbits() method for int and long types
Raymond Hettinger rhettin...@users.sourceforge.net added the comment:
In the whatsnew docs, add two lines showing the binary representation of
37. That will provide clarification as to why the answer is six:
n = 37
+ bin(37)
+ '0b100101'
n.bit_length()
6
Also, the main entry in the docs should be built-out just a bit. I like
that the current entry provides a precise mathematical spec that is
easily validated, but it should also mention the more intuitive notion
of the number of bits in a number's binary representation excluding
leading zeros (for example the decimal number 37, which is 0b100101 in
binary, has six binary digits).
Possibly, the BitLengthTables can be dropped in favor of the old
shift-one, add-one code (to be inserted right after the shift-eight,
add-eight code). The two tables consume a lot of memory and the
relevant entry is not likely to be in cache when needed (cache misses
are very slow). It is simpler and possibly faster to skip the table
lookup unless the table is made much smaller. Plus, it makes the code a
bit more maintainable and self-evidently correct (not requiring as
extensive test coverage to validate the whole table).
My own crack at optimization looks like this:
static const char BitLengthTable[32] =
{0, 1, 2, 2, 3, 3, 3, 3, 4, 4, 4, 4, 4, 4, 4, 4,
5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5};
while (n = 32) { r += 5; n = 5; }
r += (long)(BitLengthTable[n]);
If you don't adopt mine, at least consider making a table of chars
instead of longs (this will give a 4:1 or 8:1 table compression,
reducing the memory footprint and increasing the likelihood of a cache hit).
I would feel better about the test code if it also directly validated
the definitions in docs and thoroughly exercised the tables:
for x in range(-65000, 65000):
k = x.numbits
if x 0:
assert 2 ** (k-1) = x 2**k
assert k == 1 + math.floor(math.log(x) / math.log(2))
elif x == 0:
assert k == 0
else:
assert k == (-x).numbits()
Other than that, I'm basically happy with the patch.

[issue4561] Optimize new io library
Antoine Pitrou pit...@free.fr added the comment: I know that as hard as it might be for everyone to believe, there are a lot of people who crank lots of non- Unicode data with Python. But cranking data implies you'll do something useful with it, and therefore spend CPU time doing those useful things (likely much more CPU time than you spent read()ing the data in the first place). In any case, you can try to open your file in unbuffered mode: open(foobar, rb, buffering=0) it will bypass the Python buffering layer and will go directly to the raw C unbuffered object. (e.g., okay, they work with bytes instead of strings, but is the bytes type really all that different from the old Python 2 str type?) No. It's a bit more limited, doesn't support autoconversion to/from unicode, but that's all. ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue4561 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue4561] Optimize new io library
David M. Beazley beaz...@users.sourceforge.net added the comment: I wish I shared your optimism about this, but I don't. Here's a short explanation why. The problem of I/O and the associated interface between hardware, the operating system kernel, and user applications is one of the most fundamental and carefully studied problems in all of computer systems. The C library and its associated I/O functionality provide the user- space implementation of this interface. However, if you peel the covers off of the C library, you're going to find a lot of really hairy stuff in there. Examples might include: 1. Low-level optimization related to the system hardware (processor architecture, caching, I/O bus, etc.). 2. Hand-written finely tuned assembly code. 3. Low-level platform-specific system calls such as ioctl(). 4. System calls related to shared memory regions, kernel buffers, etc. (i.e., optimizations that try to eliminate buffer copies). 5. Undocumented vendor-specific proprietary system calls (i.e., unknown magic). So, you'll have to forgive me for being skeptical, but I just don't think any programmer is going to sit down and bang out a new implementation of buffered I/O that is going to match the performance of what's provided by the C library. Again, I would love to be proven wrong. ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue4561 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

In any case, binary reading has acceptable performance in py3k (although 3x-4x slower than in 2.x), it's text I/O which is truely horrendous. ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue4561 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Antoine Pitrou pit...@free.fr added the comment: I don't agree that that was a worthy design goal. I don't necessarily agree either, but it's probably too late now. The py3k buffered IO object has additional methods (e.g. peek(), read1()) which can be used by upper layers (text IO) and so can't be replaced with the old 2.x file object. In any case, Amaury has started rewriting the IO lib in C (*) and getting good binary IO performance shouldn't be too difficult.

Most people who get bright ideas such as gee, maybe I'll write my own version of X where X is some part of the standard C library pertaining to I/O, end up fighting a losing battle. Of course, I'd love to be proven wrong, but I don't think I will in this case. As for cranking data, that does not necessarily imply heavy-duty CPU processing. Someone might be reading large datafiles simply to perform some kind of data extraction, filtering, minor translation, or other operation that is easily carried out in Python, but where the programs are still I/O bound.

[issue4675] urllib's splitpasswd does not accept newline chars in passwords
New submission from Mihai Ibanescu mihai.ibane...@gmail.com:
According to http://www.ietf.org/rfc/rfc2617.txt section 2, in basic
HTTP authentication the password can be any character (including newline).
urllib does the following:
_passwdprog = re.compile('^([^:]*):(.*)$')
That should be changed to:
_passwdprog = re.compile('^([^:]*):(.*)$', re.S)
otherwise newlines will not be caught by the second part of the regex,
and bad things are produced.
For a password with regular chars in it:
python -c import urllib; print urllib.splitpasswd('user:ab')
('user', 'ab')
For a password with a newline:
python -c import urllib; print urllib.splitpasswd('user:a\nb')
('user:a\nb', None)
The expected result should have been ('user', 'a\nb')

Mark Dickinson dicki...@gmail.com added the comment:
Thanks for all the comments. Here's an updated patch, with quite a few
changes:
code:
- drop lookup tables in favour of while(x) {x = 1; count += 1;}
- add example to docstring, and use PyDoc_STRVAR macro for docstrings
docs:
- add bin(37) to whatsnew example
- move main documentation out of the bit operations table into its own
subsection, so that it can be indexed properly.
- expand main documentation with examples, informal definition,
equivalent Python code
- I dropped the 1 + math.floor(...) definition from the docs, judging
that 1 informal, 1 formal and 1 Python definition should be enough.
tests:
- as proposed by Raymond, directly check equivalence with formal
definition, equivalent Python code, and two other possible definitions.
(FWIW I prefer 'x1' over 'x//2' in the Python code, because it's more
immediately related to the intended sense: the operation should be
thought of as a bit shift rather than a division.)

New submission from Somelauw somel...@yahoo.com: I'm using python 3.0 final which was released on December the 3th. I also have python 2.5 installed. 2 bugs in python3 IDLE which might be related (but don't have to) 1. The Python3 IDLE sometimes suddenly closes. It always happens when I'm using it for a while, then press the shift + home or end key and then it just disappears and my unsaved work is lost. It really completely exits without an error and I also don't see it on the background. I'm unable to reproduce the error. But it usually happens when I have hold down shift and press the home key. 2. When I have some code then scroll down the code, then hold down shift and press up a few times, then press home the selected code completely switches. Instead some code above the cursor suddenly gets selected. The reason I think both are related is because both involve shift + home key. Both of the bugs have never happened in the IDLE 1.2.1 which was part of python 2.5.2 I think -- components: IDLE messages: 77921 nosy: Somelauw severity: normal status: open title: python3 closes + home keys versions: Python 3.0 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue4676 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue3439] create a numbits() method for int and long types
Raymond Hettinger rhettin...@users.sourceforge.net added the comment:
Of course, the name should have been bit_length() instead of numbits().
For the code equivalent, I'm aiming for something less process oriented
and more focused on what it does. bit_length IS the number of bits in a
binary representation without the sign or leading zeroes -- that
definition IS a correct mental picture and does not require special
cases for zero or for negatives.
The purpose of the code equivalent is not efficiency or beauty; it to
help communicate was a function does. If you want it to be more
beautiful, it can be broken into multiple lines.
I don't think you gain ANY explanatory power with code that says:
bit_length is the number of right-shifts (or floor divisions by two) of
the absolute value of a number until that number becomes zero. Tell
that description to a high school student and prepare for a blank stare.
FWIW, I think having a mental picture that was too process oriented was
behind last night's mistake of thinking the (16).bit_length() was 5
instead of 4. I theorize that error wouldn't have occurred if the
mental picture was of len('1') instead of power-of-two mental model
where people (including some of the commenter here) tend to get the edge
cases wrong.
It would be better to have no code equivalent at all than to present the
repeated //2 method as a definition. That is a process, but not a
useful mental picture to help explain what bit_length is all about.
Think about it, bit_length() is about the length in bits of a binary
representation -- any code provided needs to translate directly to that
definition.
def bit_length(x):
'''Length of a binary representation without the sign or leading zeroes:
(-37).numbits()
6
'''
s = bin(x) # binary representation: bin(-37) -- '-0b100101'
s = s.lstrip('-0b') # remove leading zeros and sign
return len(s)

[issue4678] Unicode: multiple chars for high code points
New submission from Eric Eisner e...@mit.edu:
I discovered this when trying to splice a string containing unicode
codepoints higher than U+
all examples on 32-bit Ubuntu Linux
python 2.5.2 (for comparison):
sys.maxunicode # 1114111
len(unichr(66674)) # 1
len(u'\U00010472') # 1
len(u'Ѳ') # 2
unichr(66674)[0] # u'\U00010472'
python 3.0: (same behavior on ubuntu's rc1 package and my build(r67781)
from svn)
sys.maxunicode# 65535
len(chr(66674)) # 2
len('\U00010472') # 2
len('Ѳ') # 2
chr(66674)[0] # '\ud801'
I expect the nth element of a string to be the nth codepoint, regardless
of unicode settings. I don't know why the maxunicode is configured
differently (both compiled by ubuntu), but is this the expected behavior?
If this is actually the expected behavior, how can I configure a build
of python to use the larger maxunicode value?

You are seeing the different behavior because you've probably
built Python 3.0 from source and used the Ubuntu default Python
install for comparison:
The default Python 3.0 build will create a UCS2 unless you specify
the --enable-unicode=ucs4 configure option.
The Ubuntu Python build (like many other Linux distros) uses this
option per default.

[issue4679] Fork + shelve causes shelve corruption and backtrace
New submission from Alex Roper al...@ugcs.caltech.edu: Hi, I wrote a simple script (attached) to do some preprocessing of MediaWiki XML dumps. When it has a 8 MB chunk ready to dump to disk, it forks, and the child writes it out and (will) compress it, then exit. The main thread continues as before. Note that the child thread never touches (or executes code that has in scope) the shelve handle. The attached script, as written, will work fine on dumps (I tested it on enwikisource-20081112-pages-articles.xml available from http://download.wikimedia.org/enwikisource/20081112/). If you uncomment the fork on line 40 (and the exit() on line 46 of course) and run it, it will die after writing out about 450 megabytes with the backtrace below. This appears to happen deterministically at the same place 3 of the 3 times I ran it. Apologies for the size and complexity of the test, I don't have time to reduce it further at the moment, and it looks like it may be fairly involved. I can try to work out a reduced case later and resubmit if no one wants to touch this as is;) # I ran the script with: bzcat enwikisource-20081112-pages-articles.xml.bz2 | ./convert.py wikisource 8388608 # (after making a dir called wikisource) Let me know if I can be of any assistance, and apologies if this is somewhere documented and I missed it.

[issue1524639] Fix Tkinter Tcl-commands memory-leaks
Guilherme Polo ggp...@gmail.com added the comment:
Something like the proposed patch is still needed. But allow me to point
out my views towards your current patch:
* Changes in Misc.after, Misc._bind: good
* Changes in Misc.unbind can be simplified a bit:
cbs = self._bind_names(self._bind(('bind', self._w), sequence,
func=None, add=None))
could be only:
cbs = self._bind_names(self.bind(sequence))
and the comment in the end should go.
* Changes in Misc.unbind_all and Misc.unbind_class can be simplified in
the same as as Misc.unbind (just change self.bind by self.bind_all and
self.bind_class)
* Changes in Variable: would you care to elaborate more on these ? Do
you need a new _tclCommands there and also use the _tclCommands from its
master ?
* Changes in Misc._options are somewhat fine.
- The comment about Python 2.3, 2.4, 2.5 being bugged because a Tcl_Obj
is returned is misleading, so you should change it.
- What are you gaining by sorting the cnf keys ?
* Changes in Misc._configure uhm.. it is hard to like that one =) Since
we are after commands created, why can't we just check the _tclCommands
before and after calling tcl here ? So we just remove the difference
(maybe move it to a set?) and don't do all those checks in case of
error, and then reraise the error.
* Changes in Wm.wm_protocol: I almost like it, except that there are two
checks for a callable arg now.
Hopefully you are still around.
