[issue23290] Faster set copying

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

Except one error (the declaration after the code), the patch LGTM. It is shame 
to me that I left so much non-optimized code in specialized loops.

The result of my microbenchmarks is the speed up 51%, 153%, 23% and 96% 
respectively.

[issue23637] Warnings error with non-ascii chars.

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

One of the worst things in Python 2 is that all can work on author's machine in 
ASCII-only environment, but then unhelpfully fail on user machine with 
non-ASCII data. Especially when needed a combination of few conditions for the 
fail. This issue is about one of such cases. And even worse, it makes the 
program fail with unfriendly error message during an attempt to output possible 
helpful warning. It is very desirable to me to solve it.

[issue23757] tuple function gives wrong answer when called on list subclass with custom __iter__

[Stuart Bishop]

Stuart Bishop added the comment:

Can we get this reopened? As David MacIver points out, this seems entirely a 
wart in tuple's constructor (compared to all the other builtin types), whereas 
10977 is worrying about how 3rd party code using the C API can corrupt 
subclasses of builtin types (a much larger scope, and much less likely to be 
resolved in a good way).

Does it make sense to require python code wishing to case a tuple or tuple 
subclass do so using tuple(list(o)), or should tuple(o) work as expected? The 
primary use is of course converting a mutable sequence to an immutable 
representation to use as a dict key.

-if (dictresize(mp, Py_SIZE(seq))) {

If Py_SIZE(seq) is 1, dictresize argument is 0.

Why not wryte the expression as Py_SIZE(seq) * 3 / 2? It never overflows, 
because Py_SIZE(seq) is the size of allocated array of pointers.

[issue24172] Errors in resource.getpagesize module documentation

[R. David Murray]

R. David Murray added the comment:

Indeed, we should probably be referring people to their system's man pages for 
the authoritative definition of most of these fields.

According to the man pages project getpagesize is no longer a POSIX API, and 
that should probably be noted as well (ie: it isn't present on all systems, and 
furthermore it is isn't accurate on all systems where it is 
present...apparently older GCCs got it wrong).

[issue23971] dict(list) and dict.fromkeys() doesn't account for 2/3 fill ratio

[Mark Dickinson]

Mark Dickinson added the comment:

>From the patch:

-if (dictresize(mp, Py_SIZE(seq))) {
+if (dictresize(mp, Py_SIZE(seq) / 2 * 3)) {

Isn't there a risk of signed overflow here?  The dictresize function has an 
`assert(minused >= 0)`, which is going to fail for values of `Py_SIZE(seq)` 
that are close to `PY_SSIZE_T_MAX` in the common case where signed overflow 
just wraps modulo the appropriate power of 2 (though it's undefined behaviour, 
so in theory it *could* do anything).

[issue5633] fix for timeit when the statement is a string and the setup is not (and tests)

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

Definitely there is a bug. The code of timeit is written to support string stmt 
and callable setup. Expected that locals available when the function is 
created, would be available when the function is executed. But this doesn't 
work. May be it worked in the earlier Python, I don't know. Due to the lack of 
tests this was unnoticed.

Here is simpler patch that fixes the support of callable setup with string stmt.

But I like Tim's approach (compile testing function using the single template), 
it makes the implementation simpler. I'll try to adapt it for current sources.

[issue24176] Incorrect parsing of unpacked expressions in call

[Thomas Caswell]

New submission from Thomas Caswell:

On the current tip (changeset: 96023:4b5461dcd190) the following results in a 
syntax error

def test(a='a', b='b'):
print(a, b)

opta = dict()
optb = dict(a=1, b=2)
test(**(opta or {}))  # <- works on all python
test(**optb or {})# <- fails on current hg tip


This is suspected to be a result of 
https://hg.python.org/cpython/rev/a65f685ba8c0 

This was reported as an issue against sphinx 
(https://github.com/sphinx-doc/sphinx/pull/1889) and I was redirected here.

As suggested by Robert Lehmann suggests the issue is 
https://hg.python.org/cpython/rev/a65f685ba8c0#l1.33 which should be `** test`. 
 Making this change prevents the syntax error (patch attached).

[issue23699] Add a macro to ease writing rich comparisons

[Petr Viktorin]

Petr Viktorin added the comment:

>From the discussion on the list:

- It needs to be a macro, not function, to support various types (unsigned long 
long, float; possibly C++ stuff with overriden operators)

- Another suggestion to change the order of arguments; I still think being the 
same as richcmp and PyObject_RichCompareBool is best.

I believe all the issues raised here and on the list are handled. Could anyone 
re-review the patch?
If the usage changes are too much, it's possible to only change 
Include/object.h and Doc/c-api/typeobj.rst, and leave the rest. Should I trim 
the patch that way?

Anything else I can do to help this get merged?

Eric, is there any chance this can land in 3.5?  OrderedDict is a heavily used 
thing, everyone will benefit from a fast implementation.  It's OK if we have an 
imperfect (but fully compatible with existing OrderedDict) implementation in 
3.5.  We can optimize it in 3.6.

[issue24177] Add https?_proxy support to http.client

[Demian Brecht]

New submission from Demian Brecht:

http_proxy and https_proxy are common environment variables used cross 
platform. Currently, urllib.request has support for it, but http.client does 
not. It probably should.

If support is added to http.client, the handling of proxy environment variables 
in urllib.request should be factored out and made to be reliant on the changes 
in http.client (which shouldn't require any new code, only removal).

Given the common usage of the environment variables (as observed by other 
utilities such as wget and curl), it seems odd to require a user to know about 
and use the higher level urllib.request API rather than have support for it 
baked into the lower level http.client API.

New submission from Yury Selivanov:

The attached patch makes Locks, Conditions, Semaphores, and BoundedSemaphores

Because the patch contains a file that will only be checked in to the CPython

of asyncio GH repo.

That doesn't matter.  The minimum dict size is 8.

Because I prefer the / 2 * 3 style so I don't have to think about whether seq 
can overflow.  Do you really feel like bike-shedding this?

[issue23699] Add a macro to ease writing rich comparisons

[Petr Viktorin]

Petr Viktorin added the comment:

Is it really not better to give the operation a name, rather than repeating the 
same ten lines every time? (Well, not the same -- all the modules code it a bit 
differently, but with the same meaning.)

I might be true that the types in Python itself are "done", but this is 
intended as part of the C API. There are still modules unported to Python 3, 
for which *now* is the beginning.

[issue23699] Add a macro to ease writing rich comparisons

[Raymond Hettinger]

Raymond Hettinger added the comment:

I'm -1 on this whole concept and I don't believe that it will make porting 
easier.  It takes longer to learn the macro, see what it does, write tests for 
it, etc than it takes to model ten lines of boilerplate code.

The macros make it harder for me and others to understand and maintain the 
code.  In this regard, Python has been getting worse (harder for new 
maintainers to look at code and know what it is doing).   Saving ten lines of 
clear code isn't a good motivation for going down this path.   C macros are 
infamous for a reason.

[issue16991] Add OrderedDict written in C

[Eric Snow]

Eric Snow added the comment:

@Yury, I'm mostly just waiting for Raymond to give it at least a quick 
sanity-check.  I know there is at least 1 ref leak, but that can be sorted out.
