[issue30785] ast.c duplicates STR(CHILD)

[Christopher Aycock]

New submission from Christopher Aycock:

The function alias_for_import_name() duplicates logic starting at 
Python/ast.c:3237

char *sch = STR(CHILD(n, i));
strcpy(s, STR(CHILD(n, i)));
s += strlen(sch);
*s++ = '.';

I assume the strcpy() is supposed to use the sch value from the line above. 
There shouldn't be any consequence to the code as it currently is; I just 
noticed it while reading through the source.

[issue17960] Clarify the required behaviour of locals()

[Nick Coghlan]

Nick Coghlan added the comment:

Guido: perhaps I should run this update through the PEP process?

Even though the actual proposed change is only to a pretty obscure edge case 
(having multiple concurrent live references to the result of locals() for a 
function namespace), the extra visibility should help developers of alternative 
implementations be clear on what is happening.

[issue30786] getaddrinfo emulation does not support AI_NUMERICSERV

[Radek Smejkal]

New submission from Radek Smejkal:

Modules/getaddrinfo.c should support AI_NUMERICSERV.

Moreover, not supporting AI_NUMERICSERV may cause troubles on platforms where 
the getaddrinfo function is available but it's buggy (see configure.ac and 
Modules/socketmodule.c), because Modules/addrinfo.h does not #undef 
AI_NUMERICSERV and Modules/socketmodule.c exports AI_NUMERICSERV defined in a 
system header that may collide with another flag defined in Modules/addrinfo.h 
and confuse the user.

./configure --with-pydebug
Comment out HAVE_GETADDRINFO in pyconfig.h
Comment out ENABLE_IPV6 in pyconfig.h on platforms where getipnodebyname and 
friends are not available

[issue30773] async generator receives wrong value when shared between coroutines

[Chris Jerdonek]

Chris Jerdonek added the comment:

Note that the example can be further simplified by replacing user() with:

async def send_hello(g):
print("sending: hello")
await g.asend("hello")

Then the output is:

sending: hello
received hello
sending: hello
sending: hello
received None
received None

[issue24813] Redesign Help => About IDLE, make it non-modal

[Cheryl Sabella]

Cheryl Sabella added the comment:

Is this the re-arrangement?  

A. What the patch does not do is switch from buttons to blue-underlined links, 
as I have discussed elsewhere, nor do other rearrangements and changes.  I want 
to move What's New to the top, move the Python license and copyright to the 
bottom, and remove Python credits.  The idle-dev email must be replaced with a 
link to the idle-dev subscription page, as spam (which continues) prompted a 
switch to subscription required.  This will be a separate issue.

Sounds like you want to make the change, but let me know if you'd ike me to 
take a shot at it.

[issue30283] [2.7] Backport test_regrtest (partially) on Python 2.7

[STINNER Victor]

STINNER Victor added the comment:

I backported almost all regrtest features from master to 2.7. It should ease 
the development on Python 2.7 ;-)

I added a NEWS entry, thanks Serhiy for the reminder. Hopefully, with NEWS.d/ 
and blurb, we will get much less conflicts on NEWS entries now ;-)

I'm aware of a last bug: "./python -m test -R 3:3 test_regrtest" hangs on 
Windows, but I'm quite sure that it comes test_crashed() which opens a popup 
and I'm working on a fix. Anyway, I already opened a specific issue for that: 
bpo-30705.

It was a long journey (2 months), but I'm now quite happy to get a much 
features-full regrtest on Python 2.7!

Spoiler: You can also expect my bisect tool in next weeks in Python 2.7 as well 
;-)

[STINNER Victor]

STINNER Victor added the comment:

I backported almost all regrtest features from master to 3.5. You should now 
get almost the same tool, even if the implementation is much older (regrtest 
was deeply reworked in master, a new test.libregrtest package was created).

I added the NEWS entry.

I now close the issue.

[issue30302] Improve .__repr__ implementation for datetime.timedelta

[Utkarsh Upadhyay]

Utkarsh Upadhyay added the comment:

I've added the following tests to remove the 0 attributes from the repr:

self.assertEqual(repr(self.theclass(days=1, seconds=0)),
 "%s(days=1)" % name)
self.assertEqual(repr(self.theclass(seconds=60)),
 "%s(seconds=60)" % name)
self.assertEqual(repr(self.theclass()),
 "%s(seconds=0)" % name)
self.assertEqual(repr(self.theclass(microseconds=100)),
 "%s(microseconds=100)" % name)
self.assertEqual(repr(self.theclass(days=1, microseconds=100)),
 "%s(days=1, microseconds=100)" % name)
self.assertEqual(repr(self.theclass(seconds=1, microseconds=100)),
 "%s(seconds=1, microseconds=100)" % name)

I am still ambivalent about factoring the minus sign outside, though.

I've also fixed a bug in test_datetime.py which prevented execution of the 
Python implementation in Lib/datetime.py.


TODO:

  - Decide about factoring the minus sign.
  - Drop description of timedelta.__repr__ from the documentation.

[Cheryl Sabella]

Cheryl Sabella added the comment:

I've made a PR for the docstrings and comments.  I didn't change any of the 
comments separating the sections in the create* functions as I wasn't sure how 
you wanted those changed.  When reading the code, I found the comments helpful 
in that they separated each section, but whitespace might be just as helpful, 
visually.

Thanks!

It seems like "x86 Gentoo Refleaks 2.7" was fixed, I don't know how, but I 
don't care as soon as it works :-)

My commit 2d775589d98959abb9833121bd9d417003de56c0 fixed "./python -m test -R 
3:3 test_regrtest" on Windows. I tested manually.

I consider that the bugs are now fixed. (If the bug is not really fixed, I will 
just reopen the bug.)

[issue30787] Please add a comprehensive index of decorators to the documentation.

[tom kronmiller]

New submission from tom kronmiller:

It is difficult to learn what decorators there are because there is no single 
index which lists all of them (at least, I have been unable to find one).  
Instead, one must stumble across them while reading library module 
documentation.  An index listing the decorators with a short description would 
be really helpful (to me, at least).

Thanks.

[issue30769] [EASY (C)] test_execve_invalid_env() of test_os leaks references

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

Just read the code. Find the function parse_envlist() in posixmodule.c and find 
similar code checking for '='.

Even if the leak is not detected by the test (but it is detected on Linux, 
maybe you use Windows?) it exists.

os.spawnve() also should be affected by this bug and fixed by the same patch, 
because it uses the same code.

[issue30302] Improve .__repr__ implementation for datetime.timedelta

[STINNER Victor]

STINNER Victor added the comment:

> 2. Factor out the negative sign: -timedelta(seconds=60) rather than 
> timedelta(days=-1, seconds=86340).

Please don't do that. repr() is designed for developers, not end users. Don't 
make repr() implementation overcomplicated. Just dump raw data, tha's all.

If you want something more smart, use str() or even write a *new* method?

[issue30302] Improve .__repr__ implementation for datetime.timedelta

[STINNER Victor]

STINNER Victor added the comment:

What is your favorite repr() for datetime.timedelta(seconds=0)?

Since it's hard to decide which unit is the best, I suggest to not write any 
unit: either "datetime.timedelta(0)" or "datetime.timedelta()" is fine with me.

In fact, "datetime.timedelta(seconds=0)" is also ok, since seconds is the most 
common unit, no?

(Ok, to be honest, I don't really care. But I wanted to have a discussion on 
this issue ;-))

[issue30302] Improve .__repr__ implementation for datetime.timedelta

[Utkarsh Upadhyay]

Utkarsh Upadhyay added the comment:

@haypo: thanks for the input!

I will find datetime.timedelta() to be rather confusing because it does not 
explicitly tell me that the interval indeed is 0.

Between datetime.timedelta(0) and datetime.timedelta(seconds=0), I am 
ambivalent but I prefer the latter for consistency with the other repr.

[issue30742] VS2015 support for 2.7 branch

[Steve Dower]

Steve Dower added the comment:

There are *many* more fixes required than just these. We're not prepared to 
take the changes into 2.7 at this stage, and we don't want to encourage people 
to think that MSVC 14.0 or later are supported when we know that it's 
incomplete.

I'd suggest creating a fork and making your updates in that. You are welcome to 
promote it as MSVC 14.0-compatible sources for anyone else who wants to build 
2.7 from them, and you may find more contributors to help you that way.

[issue30723] IDLE parenmatch - left and right highlighting, independent flash-delay

[Terry J. Reedy]

Terry J. Reedy added the comment:

I have compared current behavior with you explanation and I agree on the 
enhancement.  'parens' seems more useful than 'default'.

'default' is a misnomer for current IDLE since the current default in 
config-extensions.def is 'expression', not 'default', I am inclined to add 
synonym such as 'opener'.  Do you have another suggestion?

On the todo list, the first item is covered by the newish Extensions tab, and 
should be removed.  What the tab lacks is input validation.  Immediately, 
pressing [Help] when on the Extensions tab should display text than included 
the parenmatch styles and the meaning of delay 0.  I will add this.

The second item mentions other Emacs stuff.  Just curious, do you know if 
'parens' is part of this?  The 'below' just mentions the 'highlight when cursor 
returns issue'.

[Charles Wohlganger]

Charles Wohlganger added the comment:

'opener' sounds fine to me. I agree it makes much more sense than 'default'.

I don't know much about Emacs, and couldn't find what their parens highlighting 
styles were. I can't think of anything sensible that isn't in this extension 
with this enhancement; apart from highlighting whenever the cursor is beside a 
parens.

[issue30788] email.policy.SMTP.fold() issue with long filenames with spaces

[Joel Hillacre]

New submission from Joel Hillacre:

Found an issue in email.policy.SMTP.fold on "Content-Disposition" headers for 
long filenames with spaces. Managed to simply the issue to a test case as 
follows:

>>> from email.policy import SMTP; SMTP.fold('Content-Disposition', 
>>> 'attachment; filename="{}"'.format('1234 67890' + '1234567890' * 6))

Below are the tracebacks various python versions produces for this code. I 
think that the difference between python 3.5 - 3.6 and 3.7 are related to the 
fix in bpo-30532.

[issue30743] unittest discover does not mention module file must be named with "test_" prefix

[Zachary Ware]

Zachary Ware added the comment:

This all seems to be covered in 
https://docs.python.org/3/library/unittest.html#test-discovery

$ cat aaaTest.py 
import unittest


class TestAAA(unittest.TestCase):

def test_something(self):
self.assertTrue(True)


if __name__ == '__main__':
unittest.main()
$ python3 -m unittest discover -v -p "*Test.py"
test_something (aaaTest.TestAAA) ... ok

--
Ran 1 test in 0.000s

OK



As the `--pattern` documentation says, the default pattern is "test*.py" which 
does not match "aaaTest.py".

You are right.

I had looking for the wrong pattern.

Thanks,

[issue30764] regrtest: Add --fail-env-changed option

[STINNER Victor]

STINNER Victor added the comment:

The initial issue, the "regrtest: Add --fail-env-changed option" feature, has 
been implemented in 2.7, 3.5; 3.6 and master branches. So I close this issue.

Again, this issue got hijacked by the test_subprocess change, bpo-30448, 
because I wrote the wrong bpo number in my commits ;-)

[issue30604] co_extra_freefuncs is stored thread locally and can lead to crashes

[STINNER Victor]

STINNER Victor added the comment:

_PyCode_SetExtra() uses two memory block for code extras. By changing how 
memory is accessed and allocated, it would be possible to use a single memory 
block. Was it on purpose to use two memory blocks?

See for example PyTupleObject which uses a single memory block vs PyListObject 
which uses two memory blocks.

typedef struct {
PyObject_VAR_HEAD
PyObject *ob_item[1];

/* ob_item contains space for 'ob_size' elements.
 * Items must normally not be NULL, except during construction when
 * the tuple is not yet visible outside the function that builds it.
 */
} PyTupleObject;

[issue30789] Redesign PyCodeObject.co_extras to use a single memory block, instead of two

[STINNER Victor]

New submission from STINNER Victor:

Currently, _PyCode_SetExtra() uses two memory block for code extras. Using a 
different structure, it would be possible to use a single memory block: less 
memory fragmentation, better CPU cache usage, less indirections, etc.

It matters since the long term plan for co_extras is to implement of kind-of 
JIT compiler insider CPython: see bpo-28158.

I discussed with Yury who is not opposed to such change in Python 3.7, so I 
created bpo-30789.
