[issue21922] PyLong: use GMP

[Hristo Venev]

New submission from Hristo Venev:

I have implemented the PyLong interface using the GMP mpn functions. API/ABI 
compatibility is retained (except for longintrepr).

It can be enabled by passing --enable-big-digits=gmp to ./configure.

No large performance regressions have been observed for small numbers (a few 
operations are about 10% slower). For large numbers some operations are a lot 
faster.

There is also int.__gcd__ which may be used by fractions.gcd.

The GIL is sometimes released. Minimum number of digis for releasing GIL: 
- multiplication - 64
- division - 64,
- modular exponentiation - 16,
- base conversion - 64 (256 for binary bases)
- GCD - 16

The tests for long, float, decimal, fractions, string, unicode, bytes, pickle, 
marshal and enum pass. The tests for int fail because the error messages are a 
bit different (when creating int from bytes or bytearray the value is not 
shown). I may have run other tests and they have not failed. I have not tested 
on anything but x86-64.

The following testcases yield 42x performace improvement:
- 16384-bit RSA on 8 threads on quad-core with HT # GIL released
- Multiplying 560-bit ints
- Dividing 600-bit ints
- Converting 30-character str to int(base=10)
- Converting 125-bit int to str

[issue21922] PyLong: use GMP

[STINNER Victor]

STINNER Victor added the comment:

Hi, I worked on a similar patch 6 years ago, while Python 3.0 was developped:
https://mail.python.org/pipermail/python-dev/2008-November/083315.html
http://bugs.python.org/issue1814

The summary is that using GMP makes Python slower because most numbers are 
small: fit in [-2^31; 2^31-1], and GMP allocation is expensive.

There is also a license issue: GMP license is GPL which is not compatible with 
the Python license.

If you want to work on large numbers, you can gmpy:
https://code.google.com/p/gmpy/

"""
The following testcases yield 42x performace improvement:

- Converting 30-character str to int(base=10)
- Converting 125-bit int to str
"""

That's not a common use case. Run the Python benchmark suite with your patch to 
see if your patch has a similar overhead than my old patch.

Hristo Venev added the comment:

PyLongObject is a PyVarObject. It contains many mp_limb_t's. There is little 
overhead. For some operations if the result is in [-20;256] no memory will be 
allocated. There are special codepaths for 1-limb operations.

And I just finished GDB support.

Please test if it works for you.

[issue21911] "IndexError: tuple index out of range" should include the requested index and tuple length

[Ezio Melotti]

Ezio Melotti added the comment:

The feature request sounds reasonable to me, unless someone proves that there 
are major (performance) issues.  However, since this has already been reported 
in #18162, I'm going to close it as a duplicate.

@Raymond
> The IndexError exception is commonly used for control flow.

Can you provide an example?  IME I rarely catch IndexErrors, and I usually use 
LBYL before accessing a random index.

> Slowing down the instantiation to add an index that no one really needs
> would be a waste.   This exception has been around for 20+ years -- if
> they were an actual need, we would have known by now.

I'm not sure the cost of adding the index is comparable with the cost of the 
whole instantiation.  Regarding the request itself see #1534607 and #18162.

@Ram
> Another possibility is to make the -O flag do this switch,

> Unfortunately I don't program in C, so I can't implement this.

It might be easier than you think.  You just need to find where the exception 
is defined and see what other exceptions like KeyError do.
Then you copy the code and adjust it until it doesn't segfault anymore and the 
tests pass.

Knowing the len of the sequence would also be useful.
Brett, were you also planning to use these attributes in the error message 
(when they are available), or do you prefer to keep the two issues separate and 
reopen #21911?

> Is there a meta-issue for these changes?

FTR the other relevant issues are:
  #18156: Add an 'attr' attribute to AttributeError
  #18163: Add a 'key' attribute to KeyError

[issue21922] PyLong: use GMP

[Stefan Krah]

Stefan Krah added the comment:

Hmm, the license (LGPL) should only matter for the Windows binaries
and we can just compile without --enable-big-digits=gmp.

Even *if* the Windows binaries were built with gmp support, it would
be sufficient for any redistributor to point to the external library
sources for gmp that the build has actually used -- your own code
does not automatically become LGPL licensed and you are under no
obligation to reveal it.


I haven't looked at the patch in detail, but I don't have any
fundamental objection against adding a configure option, provided
that the additional code is well isolated (which seems to be the
case).

Of course we'd have to set up buildbots for the option etc...

[issue21911] "IndexError: tuple index out of range" should include the requested index and tuple length

[Stefan Behnel]

Stefan Behnel added the comment:

"you'd be surprised how much cheaper indexing a sequence is relative to 
dictionary access"

This is a bit off-topic (and I realise that this ticket is closed now), but the 
difference isn't really all that large:

$ python3.4 -m timeit -s 'seq = list(range(1000)); d = {n:n for n in seq}' 
'seq[100]'
1000 loops, best of 3: 0.0263 usec per loop

$ python3.4 -m timeit -s 'seq = list(range(1000)); d = {n:n for n in seq}' 
'd[100]'
1000 loops, best of 3: 0.0285 usec per Pool

$ python3.4 -m timeit -s 'seq = list(range(1000)); d = {"test%d"%n:n for n in 
seq}' 'd["test34"]'
1000 loops, best of 3: 0.0317 usec per loop

Especially hashing strings is usually faster than you might expect, because the 
hash value is cached and strings that get hashed once tend to get hashed again 
later.

Note that KeyError doesn't do any exception message formatting on creation. It 
only includes the bare key, which is pretty quick, especially if the key is 
already a string.

In comparison, instantiating an exception takes almost three times as long:

$ python3 -m timeit -s 'K=KeyError' 'K("test")'
1000 loops, best of 3: 0.0779 usec per loop

We once had the case in Cython where dropping the instantiation of 
StopIteration at the end of generator execution gave a serious performance 
boost (more than 40% faster for short running generator expressions in the 
nqueens benchmark), but the same is less likely to apply to IndexError, which 
normally indicates a bug and not control flow. I lean towards agreeing with 
Terry that usability beats performance here.

[issue21880] IDLE: Ability to run 3rd party code checkers

[Saimadhav Heblikar]

Saimadhav Heblikar added the comment:

In v3, there is no subprocess usage.
It imports the checker specific module,does its job and returns the result of 
processing.


The checker specific files are to be installed from TestPyPI(atleast for now). 
It has to be installed via pip.
It will be detected automatically in IDLE. There will be a feature to pass 
additional arguments onto the checker(though not yet implemented in this patch).

This patch also supports the feature to modify the editor buffer.

To test out this patch, kindly install two packages
pip install -i https://testpypi.python.org/pypi IDLEPyflakes 
IDLEWhitespaceRemover

(I used the reindent.py file in Tools/scripts in IDLEWhitespaceRemover)

Again, this is more a proof of concept patch. I we are to go ahead in this 
direction, I will be writing it from scratch again and also with tests.

Checker, is actually a misnomer if we do support the "modify buffer" feature.

Mark Dickinson added the comment:

I *do* have an objection to adding the configure option:  from that point on, 
it means that maintaining the GMP-based long implementation is now the 
responsibility of the core developers, and I think that's an unnecessary 
maintenance burden, for an option that few users will care about.  I think 
having two long integer implementations in the core is worse than having one.

[issue21922] PyLong: use GMP

[STINNER Victor]

STINNER Victor added the comment:

>  I think having two long integer implementations in the core is worse than 
> having one.

I agree. If the GMP implementation is accepted, the old implementation must be 
dropped and replaced by the GMP implementation.

Mark Dickinson added the comment:

Agreed.  I'm open to that, but it's critical that common use-cases (i.e., those 
*not* using 1000-digit integers!) aren't slowed down.

[issue21923] distutils.sysconfig.customize_compiler will try to read variable that has not been initialized

[Alex Gaynor]

New submission from Alex Gaynor:

If one invokes some distutils code too early, this function will try to read 
``_config_vars`` before it is initialized. 
http://bpaste.net/show/1DOGhL8sdnkPyLTL06AZ/ is an example traceback that 
results.

The attached patch uses the public API which guarantees that it is defined.

[issue21880] IDLE: Ability to run 3rd party code checkers

[Saimadhav Heblikar]

Saimadhav Heblikar added the comment:

>This seem like a new feature for IDLE, so I'd imagine it would not be 
>>included in either 2.7 or 3.4. Correct me if I'm wrong.

Hi,
Yes, it is a new feature. I think it will be included in both 2.7 and 3.4(apart 
from the latest version 3.5), if my understanding of pep434 is correct.

>From pep434
>The PEP would apply to changes in existing features and addition of >small 
>features, such as would require a new menu entry, but not >necessarily to 
>possible major re-writes such as switching to themed >widgets or tabbed windows

Though, I cant say for sure into what category this feature would fall into, 
i.e. whether it is a "small feature" or not.

[issue21924] Cannot import anything that imports tokenize from script called token.py

[Ned Deily]

Ned Deily added the comment:

That's because there is also a standard library module named token 
(https://docs.python.org/3/library/token.html).  When you run python, by 
default the current working directory is inserted at the beginning of sys.path, 
the list of directories searched for modules.  If you have a file there that 
has the same name as a standard library module, e.g. token.py, it will be found 
first and, thus, "hide" the standard library module of the same name.  Either 
change the name of your file so it does not conflict or make sure it is in a 
directory not on sys.path.

[issue17652] Add skip_on_windows decorator to test.support

[Zachary Ware]

Zachary Ware added the comment:

The patch looks fine, but I don't see a big gain from it; call me +0.  It might 
be interesting to see a patch that converts current "@skipIf(sys.platform == 
'win32' or os.name == 'nt')" instances to "@skip_on_windows" to see just what 
kind of difference it makes, but I'm honestly more interested in seeing how 
many different ways "don't run this test on Windows" is spelled currently.

[issue21925] ResouceWarning sometimes doesn't display

[Ned Deily]

Ned Deily added the comment:

I believe this is an artifact of hash randomization which affects the order of 
how objects are destroyed during shutdown.  If you run your test using 
different values of the PYTHONHASHSEED environment variable, you'll probably 
see predictable results.  For example, with a particular build of Python 3.4.1, 
if I set PYTHONHASHSEED set to 0, thereby disabling hash randomization, I never 
see the warning:

PYTHONHASHSEED=0 python3.4 -W all test_warning.py

With it set to 1, I always see the warning.  With 2, no warning. With no 
PYTHONHASHSEED, I see random behavior similar to your results.

I don't think there is anything to be done here as Python makes no promises 
about when and in what order objects are collected.

[issue10190] Can argparse._AttributeHolder._get_kwargs become a public API?

[paul j3]

paul j3 added the comment:

Apart from sorting, `_get_kwargs` does little more than:

return [k for k in action.__dict__.items() if not k[0].startswith('_')]

That is, it's the `items()` of the 'public' attributes of the action (or 
parser).  Those attributes are already accessible to the code that is using 
'argparse'.

[issue21926] Bundle C++ compiler with Python on Windows

[Ben Lucato]

New submission from Ben Lucato:

I am wondering if it is at all on the roadmap to bundle a C compiler with 
Python on Windows, given that installing libraries with C extensions is very 
confusing on Windows.

For example, to install NumPy on Windows you end up either having to download 
the right version of Visual Studio or install it from the list of precompiled 
libraries at http://www.lfd.uci.edu/~gohlke/pythonlibs/. The problem is, either 
of those solutions feel quite bloated and aren't easily apparent when searching 
for fixes online.

BTW, since this is my first issue I looked around for a guide on how to submit 
issues but I couldn't find one - so I hope I'm raising it right.
