[issue7784] patch for making list/insert at the top of the list avoid memmoves

[showell]

showell  added the comment:

I am attaching a new patch that does not add a new element to PyListObject, 
roughly following a technique that Antoine Pitrou suggested on python-dev.  
When I want to lazily avoid a memmove under the new patch, I set the MSB on 
allocated and store the original ob_item pointer in the new ob_item[-1].

On the advice of Daniel, I ran the new patch against the Unladen benchmark 
suite.  The results were pretty neutral--never more than a 1% penalty but no 
significant gains either.  I did not expect to see gains, for the obvious 
reason that I am improving performance on an operation that folks have been 
encouraged to work around.  The new patch continues to do well on 
microbenchmarks. 

The new patch fails one test in test_sys related to the 12 byte garbage 
collection header.  The failure is definitely introduced by my patch, but I am 
not sure what it's doing wrong.  All other tests pass.

Because the new code piggybacks on top of of allocated instead of creating a 
new variable in PyListObject, the new code is a bit more complex than the 
original patch, which is unfortunate.  There are probably some opportunities 
for making the new code simpler.

[issue7784] patch for making list/insert at the top of the list avoid memmoves

[showell]

showell  added the comment:

Ok, found the offending line, now all tests pass.  

The use case where this patch will pay off the most is slicing your way through 
a list of tasks.  The toy program below gets about a 50x speedup.

import time

n = 80

lst = []
for i in range(n):
lst.append(i)

t = time.time()
for i in range(n):
x = lst[:10]
del lst[:10]

print('time = ' + str(time.time() - t))
print(len(lst))

[issue7803] setup hangs on disk space requirements

[Dan Simmons]

New submission from Dan Simmons :

I tried to install windows binary and the setup hanged up on 'determining disk 
space requirements' I waited over two hours for this to finish, and the light 
blinked in a syncrinised pattern that led me to believe something was wrong. So 
I have since restarted it and the light is blinking differently this time. Hope 
it works.

[issue7803] setup hangs on disk space requirements

[Dan Simmons]

Dan Simmons  added the comment:

I think the beginers guide needs to be updated to let us know what type of 
download to use. x86-64 or binary. 64 bit works so is that the right one for 
me. I'm trying to get this graphics.py to work that came with a book. It stops 
working when I run a module with it.

[issue7092] Test suite emits many DeprecationWarnings when -3 is enabled

[Ezio Melotti]

Ezio Melotti  added the comment:

A couple of comments about issue7092_syntax_imports_v3.diff too:
1) in test_copy you remove (k,v), but left the name 'k' even if now it 
represent the item and not the key;
2) in test_fractions you should probably use self.fail() instead of an assert;
3) on test_ftp you can use two separate lines and remove the ';';
4) in test_pyclbr there's one extra 'f' in the comment in assertHaskey;
5) in test_xml_etree_c you can either leave callable() and catch the warning or 
use isinstance(x, collections.Callable) instead (there are also a few more 
places where callable was used too).

Yes, a test could use Google or gmane (according to the FAQ, nntps is 
supported: http://gmane.org/faq.php ).
The test should skip gracefully (using the skipTest() API) if the connection

[issue7806] httplib.HTTPConnection.getresponse closes socket which destroys the response

[Robert Buchholz]

New submission from Robert Buchholz :

Calling getresponse() on an httplib.HTTPConnection object returns a response 
object. Internally, the self.sock is handed over to the HTTPResponse object 
which transforms it into a file-like object. The response object is returned to 
the caller. If one calls response.read() later on, no or incomplete content 
will be returned because the underlying socket has been closed.

The code path, simplified:

class HTTPConnection:

def getresponse(self):
response = self.response_class(self.sock, ...)
...
if response.will_close:
# this effectively passes the connection to the response
self.close()

def close(self):
if self.sock:
self.sock.close()
...

class HTTPResponse:
def __init__(self, sock, debuglevel=0, strict=0, method=None):
self.fp = sock.makefile('rb', 0)
...

[issue7803] setup hangs on disk space requirements

[Brian Curtin]

Brian Curtin  added the comment:

Dan, there seem to be a number of possible issues in your last two messages.

It's not clear to me what the blinking light is. What type of computer do you 
have and what is the specific installer and version you tried to run?

Also, what do you mean when you say that it stops working when you run a 
module? Does the interpreter crash or is there an unhandled exception which 
causes the application to exit?

It seemed to work after I restarted it. It was stuck on the process of getting 
disk space requirements, the computer was processing something but the light on 
the console that tells you something is being processed was blinking once every 
second in a obvious loop, When I started over it just processed through it in 
less than a second. So there was something wrong. I don't know if it was my 
computer or not.

[R. David Murray]

R. David Murray  added the comment:

Hmm.  That's not actually the same timeout.  What that means is that if the 
startup timeout triggers, then a subsequent test (one that is looking for the 
results of a client transaction) fails, which contradicts the earlier 
observation that even if the startup timeout fails then everything else still 
passes.

[issue7633] decimal.py: type conversion in context methods

[Mark Dickinson]

Mark Dickinson  added the comment:

The updated patch looks good---thank you!  We're getting there... :)

I'm not sure about the extra 'Operand can be Decimal or int.' in the method 
docstrings;  this just looks like extra clutter to me.  Rather, I think it 
would be a surprise worthy of documentation if these methods *didn't* accept 
int or long;  since they now do (with your patch), I don't think it's really 
worth mentioning in the docstring.  And it's not quite accurate, either, since 
these methods should accepts longs as well as ints (and bools, and instances of 
other subclasses).

Would you be content to remove these from the docstrings?  Or do others 
monitoring this issue think they should stay?

The extra doctests and test_decimal tests are nice.

Hmm.  Thanks for noticing this:  it looks like Decimal.copy_sign is missing a 
_convert_other call.  I think that should be fixed in the Decimal class rather 
than in the Context class (so Context.copy_sign and Decimal.copy_sign should 
make one _convert_other call each, instead of Context.copy_sign making two 
calls).

[issue7092] Test suite emits many DeprecationWarnings when -3 is enabled

[Florent Xicluna]

Florent Xicluna  added the comment:

Thank you for the review and your comments.
Here, the replies.

It is the 3.x syntax.
--> No change

Added the "deprecated=True"

Ok. I prepare a separate patch to fix bsddb3

Will use assertSetEqual, no need to reinvent the wheel

Ok to keep callable. For the next line, I do not see the warning.

Done

Changed 'k'-> 'pair' (like 3.x)

The surrounding methods use "assert "
--> No change

Done

It is not an extra f. 'iff' = "if and only if" (not obvious for non-English 
people)

It is done this way in 3.x.
I propose to fix it separately (if a fix is required).



Now I prepare the updated patches.
I follow the proposal of Amaury: create a specific 
"test_support.silence_py3k_warnings()" context manager.
It replaces the "check_warnings" and "filterwarnings" of the proposed patches.

[issue6766] Cannot modify dictionaries inside dictionaries using Managers from multiprocessing

[Kaushik Ghose]

Kaushik Ghose  added the comment:

Even with the patch, I can not resolve this problem. I can reproduce the 
problem with the patched version with the following code. My system is:

Python 2.6.4 (r264:75821M, Oct 27 2009, 19:48:32)
IPython 0.10
Platform is Mac OS X (10.5.8) Darwin Kernel Version 9.8.0: Wed Jul 15 16:55:01 
PDT 2009

import multiprocessing as mp

def f(d):
  d['f'] = {}
  d['f']['msg'] = 'I am here'

manager = mp.Manager()
d = manager.dict()

p = mp.Process(target=f, args=(d,))

p.start()
p.join()

print d

d = {}
f(d)

print d

Output:

{'f': {}}
{'f': {'msg': 'I am here'}}

[issue5712] tkinter - askopenfilenames returns string instead of tuple in windows 2.6.1 release

[Clovis Fabricio]

I've written a quick workaround for the issue, where I manually split the

[issue7684] decimal.py: infinity coefficients in tuples

[Mark Dickinson]

Mark Dickinson  added the comment:

Issue 1: (passing coefficients to decimal constructor):  While I agree that 
passing a coefficient for an infinity doesn't make a lot of sense, there's a 
backwards compatibility problem here: it worked in 3.1, so making it raise an 
exception in 3.2 might break code.  However, it seems unlikely that there's any 
correct code out there that's passing a coefficient other than (0,) or () for 
an infinity, so I'd be prepared to make this an error for coefficients other 
than () and (0,).

Issue 2: (inf.as_tuple() returns () instead of (0,) for coefficient).  On 
balance I'd prefer to leave this as it is.  It's a minor inconsistency, but I 
don't think it really does any harm.  Unless there's a real bug, making a minor 
change like this to an established API seems more likely to do harm than good.  
(It could break docstrings in third-party packages, for example.)

[issue7784] patch for making list/insert at the top of the list avoid memmoves

[showell]

showell  added the comment:

I am closing this due to mostly unanimous rejection on python-dev.

If folks reopen this in the future, the last patch that I submitted has been 
reasonably well tested, but it has not been code reviewed.

The 1% speed penalty could probably be driven down without too much effort, but 
not totally eliminated.

The constraint not to add a member to PyListObject complicates the code 
considerably.

In diving deep into listobject.c, I noticed a couple things unrelated to my 
patch:

  1) There might be a refactoring available for calls to list_resize, where 
callers just pass in the delta, instead of the new list size.  Lots of the 
callers do addition that could be pushed into list_resize.  Not sure it would 
lead to speed ups, but it would probably reduce code size.

  2) The optimistic realloc scheme is probably needlessly wasteful for really 
large lists.  If you have a million elements, I am not sure you need to 
allocate 12% extra space, and I think that's what the current algorithm does 
(untested).

  3) There might be some merit in splitting out list_resize into 
list_resize_bigger and list_resize_smaller.  I think the callers generally know 
when they are shrinking/expanding the list, so callers that are shrinking the 
list could call a leaner method that just shrinks the list without having to 
execute other instructions.

[issue7633] decimal.py: type conversion in context methods

[Stefan Krah]

Stefan Krah  added the comment:

I also think that the added docstrings are not really necessary.

Another thing: I forgot to mention 'canonical' in the list of functions
that should only accept Decimals. As with the other two (number_class
and is_canonical), this is a matter of taste. Personally I would not
expect them to work for integers.

[issue7633] decimal.py: type conversion in context methods

[Mark Dickinson]

Mark Dickinson  added the comment:

Re: canonical.  Yes, this made me pause for a second, too.  But I don't see the 
harm in allowing it to accept ints and longs.  Actually, it then provides a 
nice public version of _convert_other.

I'd probably also allow is_canonical and number_class to accept ints and longs, 
just on the basis that that gives fewer special cases.

[issue7771] dict view comparison methods are not documented

[Terry J. Reedy]

Terry J. Reedy  added the comment:

The 3.2a doc is unchanged (similarly lacking).

The situation is that view have all of the special method (operator methods) 
that frozen sets do but none of the named methods (.copy to .union). I think it 
would be helpful if the doc said so. Perhaps change

"Then these set operations are available ..."

to

"For set-like view, all of the syntax operations on sets (but none of the named 
methods, like set.copy,) are available ..."

I think

dictview < / <= / >= / > other:
 same as corresponding operation with two sets

might be sufficient, but list all four is ok too.

It's normally not ok to ignore the deprecation process for 3.x,
since the 3.x branch is in a stable state, just like the 2.x
branch (3.0 and, after some discussions, 3.1 were allowed to
break things).

I don't know why this process wasn't followed for the new GIL
implementation.

It basically breaks compatibility with the other
thread implementations, but does so without actually removing
the support for them in the thread library we're using for
the _thread module.

Perhaps this was simply not known to other developers.

There's also no PEP for the new implementation, which you'd
normally require for any such major change to the internals.

Breaking existing applications and ports of Python for 2.7
certainly won't make anything easier for anyone.

For 2.7 we will certainly not allow the above to happen,
since that's the version that's going to be used by most
people for a few years to come.

What we could do for 2.7, is add Py3k deprecation warnings
to the alternative thread implementations, mentioning their
removal in 3.2.

[issue7633] decimal.py: type conversion in context methods

[Stefan Krah]

Stefan Krah  added the comment:

Yes, indeed 'canonical' can be justified to take an integer, if we interpret 
the spec as:

'canonical' takes an operand and returns the preferred _decimal_
encoding of that operand.

But then 'is_canonical' should return false for an integer, and
this would create another special case: Accept an operand and
return something meaningful _without_ converting it first.

I think this is why I have problems with those two. 'number_class'
is less of a problem.

What if, as you proposed earlier, the patch were to leave the old
behavior if the threading model on the given platform were not
supported?

py3k version.

Let me know if I should create a new patch or if I should create one for py3k.

Thanks for the review.

[issue6766] Cannot modify dictionaries inside dictionaries using Managers from multiprocessing

[Terrence Cole]

Terrence Cole  added the comment:

Kaushik, in your example, d is a dict proxy, so assignment to d['f'] correctly 
ferries the assignment (a new normal dict) to the d['f'] in the original 
process.  The new dict, however, is not a dict proxy, it's just a dict, so 
assignment of d['f']['msg'] goes nowhere.  All hope is not lost, however, 
because the Manager can be forked to new processes.  The slightly modified 
example below shows how this works:

from multiprocessing import Process, Manager
def f(m, d):
d['f'] = m.dict()
d['f']['msg'] = 'I am here'

m = Manager()
d = m.dict()
p = Process(target=f, args=(m,d))
p.start()
p.join()
print d
{'f': }
print d['f']
{'msg': 'I am here'}

With the attached patch, the above works as shown, without, it gives the same 
output as your original example.

[issue6978] compiler.transformer dict key bug d[1,] = 1

[Meador Inge]

Meador Inge  added the comment:

I think this should be closed out, since the compiler package was deprecated in 
2.6.

[issue7809] Documentation for random module should indicate that a call to seed() is not required

[Justin Lebar]

New submission from Justin Lebar :

Many programmers are used to languages where the RNG is deterministic unless 
it's explicitly seeded.  This does not appear to be the case in Python.

The documentation for random should indicate that Random objects are seeded on 
construction, and that the global random object is seeded when the random 
package is first imported.

[issue7809] Documentation for random module should indicate that a call to seed() is not required

[Ezio Melotti]

Ezio Melotti  added the comment:

It's already indicated in the documentation for random.seed([x]):
"If x is omitted or None, current system time is used; current system time is 
also used to initialize the generator when the module is first imported."

[issue7809] Documentation for random module should indicate that a call to seed() is not required

[Justin Lebar]

Justin Lebar  added the comment:

Ack.  I read it twice looking for that line!

Perhaps it should still indicate that new Random objects are automatically 
seeded.  And perhaps the line I missed should be a little bit louder?
