[Karthikeyan Singaravelan]

Karthikeyan Singaravelan  added the comment:

It seems that the last successful build in 3.7 was for 
https://github.com/python/cpython/commit/339e0c1296c61c9dbc1f8f880c5c668bf4007e5e
 and all PRs after it had the same failure.

Sorry for not adding the relevant components during ticket creation.

[issue34136] Del on class __annotations__ regressed, failing test

[Serhiy Storchaka]

Serhiy Storchaka  added the comment:

In the edition of PR 8364 the test is failed on 3.6.

def test_do_not_recreate_annotations(self):
annotations = {}
# Don't rely on the existence of the '__annotations__' global.
with support.swap_item(globals(), '__annotations__', annotations):
class C:
del __annotations__
x: int  # Updates the '__annotations__' global.
self.assertIn('x', annotations)
self.assertIs(annotations['x'], int)

It is possible to write it in less strong form which will be passed on 3.6 too.

def test_do_not_recreate_annotations(self):
# Don't rely on the existence of the '__annotations__' global.
with support.swap_item(globals(), '__annotations__', {}):
del globals()['__annotations__']
class C:
del __annotations__
with self.assertRaises(NameError):
x: int

In 3.6 the annotation declaration fails immediately if __annotations__ is 
deleted. In 3.7 it falls back to the global __annotations__.

The question is whether the difference in the behavior between 3.6 and 3.7 is 
intended and is a part of the language specification, or is an implementation 
detail of CPython. In the former case we can keep the stronger test. In the 
latter case we should make it weaker.

[issue34172] multiprocessing.Pool and ThreadPool leak resources after being deleted

[tzickel]

tzickel  added the comment:

>>> from multiprocessing import Pool
>>> import gc
>>> a = Pool(10)
>>> del a
>>> gc.collect()
0
>>>

After this, there are still left behind Process (Pool) or Dummy (ThreadPool) 
and big _cache data (If you did something with it) which lingers till the 
process dies.

You are correct on the other issue (I'm using and reading the Python 2 
documentation which does not have that...).

[issue25094] [EASY][Windows] test_tools fails on Windows when passing

[Lorenz Mende]

Lorenz Mende  added the comment:

Approving the behaviour on 3.6.5 and fresh cpython-built @master:

>From the docs: test_sundry "contains extremely basic regression tests... which 
>don't have separate tests of their own".

IMHO 2to3 can be added to the whitelist of test_sundry as it comes with its own 
unit tests. When test_sundry runs import_tool with '2to3', lib2to3 is called 
without args, resulting in an exit 2 which breaks the basic test.

[issue28009] core logic of uuid.getnode() is broken for AIX - all versions

[Michael Felt]

Michael Felt  added the comment:

OK. as promised when I closed PR 5183 - a restart.

You may skip the wall that follows - it is just documentation.

The key points:
* AIX ifconfig and arp do not supply maccaddr
* netstat supplies a macaddr, but uses '.' not ':' as a delimiter
** also, AIX netstat value is not always 17 characters (dec 15 is 'f' not '0f')
* since Python3-3.7 there is support for _uuid so test_unix_getnode passes 
"WithExtModule" but fails "WithoutExtModule"

A minor point:
test_find_mac() has always passed on AIX because the test was passed a
macaddr using ':' and tested for ':'. The test has been modified to provide a 
macaddr in "AIX" format. IMHO - the test would be better if the string was not 
"forced to be 17 characters" (e.g., this is my macaddr as returned by netstat: 
"0.12.a3.53.c9.46"

My question - getting back to what I had done previously - even though _uuid is 
working, should the "WithoutExtModule" and support for test_find_mac() be 
adjusted in uuid.py - OR - are these errors in test just going to be accepted 
asis?

Details: (skip the wall :p )


So, with only test_uuid.py patched, the verbose returns ('ok' tests not 
included!):

[issue28055] pyhash's siphash24 assumes alignment of the data pointer

[Jeffrey Walton]

Jeffrey Walton  added the comment:

I know this is a bit late but I wanted to share...

OpenCSW has a build farm with Solaris machines and Sparc hardware. The farm 
provides x86 and Sparc machines with Solaris 9 through 11.

I believe OpenCSW operates in the same spirit as GCC compile farm. They welcome 
open source developers and upstream maintainers to help ensure packages build 
and run on Solaris machines.

You can read about it at
https://www.opencsw.org/extend-it/signup/to-upstream-maintainers/ .

If Python is performing memory access patterns as discussed in the report then 
it would probably benefit the project to test on a Sparc machine with Solaris 
11.

[issue34169] itertools.repeat does not accept None as an explicit count

[Clint Hepner]

Clint Hepner  added the comment:

This came up in response to https://stackoverflow.com/q/51443795/1126841.

I realize the current documentation is informative, not normative, but I think
there is a legitimate reason to allow an explicit None argument like the pure 
Python suggests.

Currently, there is no way to trigger the default behavior explicitly, as 
repeat behaves more like iter (in that the number of arguments has special 
meaning) than like islice (whose optional arguments behave like regular 
parameters with default values).

For example, these two calls are equivalent:

islice(itr, 5) 
islice(itr, 5, None)

For some functions, it makes sense for the number of arguments to be 
significant. For example, there is no meaningful default value for the second 
argument to iter(), since the second argument completely changes the semantics 
of the call.

iter({'a': 1, 'b': 2})  # Return an iterator for the argument
iter(lambda f: f.read(4), '')  # Call a function until it returns ''

As an another example, the first argument to map() determines how many
additional arguments are needed.

map(lambda x: x + 1, [1,2,3])   # yield values form [2,3,4]
map(lambda x: x + y, [1,2,3], [1,2,3])  # yield values from [2,4,6]


However, with repeat(), it makes sense to think of the second argument as an 
upper limit that can be either finite or infinite. Lacking an infinite integer 
value, None makes sense if you read it as "no upper limit"


repeat(1) # infinite stream of 1s
repeat(1, 10322)  # a finite stream
repeat(1, None)   # proposed: an infinite stream of 1s

I prefer the current description of

def repeat(object, times=None):

over

def repeat(object, *times)

because it accurately reflects the number of arguments you can pass to repeat.

[issue34180] bool(Q) always return True for a priority queue Q

[Victor Porton]

New submission from Victor Porton :

It seems that bool(Q) always return True for a priority queue Q.

It should behave the same way as for bool(L) where L is a list, that is return 
False on an empty queue.

Please check also other objects in https://docs.python.org/3/library/queue.html

After the bug is fixed, the documentation should be clear that there was a 
change in the behavior in certain Python version.

Relevant SO answer : https://stackoverflow.com/a/41861322/2610955

Ref : https://docs.python.org/3/reference/datamodel.html#object.__bool__

> If a class defines neither __len__() nor __bool__(), all its instances are 
> considered true.

I don't know why it's not implemented and the SO answer comments has some 
discussion. Maybe this can be clarified in the doc.

[issue34136] Del on class __annotations__ regressed, failing test

[Guido van Rossum]

Guido van Rossum  added the comment:

Thanks for the research. At this point I'm wondering what this test is testing. 
There is no prescribed behavior once you delete __annotations__ from the scope 
-- it is not a supported operation. At the same time I don't want to add any 
code enforcing that it fails. Unless you disagree, I think in 3.6 we should 
just delete the test.

[issue34173] [3.7] possible race condition in /usr/lib/python3.7/concurrent/futures/thread.py

[Karthikeyan Singaravelan]

Karthikeyan Singaravelan  added the comment:

I looked into the code of test_execute_multiple_tasks and 
designate/worker/processing.py from which the executor was initialized. I have 
converted the test case code removing the project related code as a standalone 
script. I hope the attached code is the minimal code required. The change from 
Queue to SimpleQueue was made with commit : 
ab74504346a6e2569b3255b7b621c589716888c4 and relevant issue is 
https://bugs.python.org/issue32576 .

I ran the test code by checking out each commit obtained by `git log --oneline 
--format="%h" Lib/concurrent/futures/thread.py` . The tests finish successfully 
without any hanging as below

[issue34178] test_tcl fails on the 3.7 branch

[Karthikeyan Singaravelan]

Karthikeyan Singaravelan  added the comment:

Thanks by install do you mean running the test with an installed version of 
python 3.7.0 from package manager or as a downloaded binary ? I can reproduce 
it with an installed version from anaconda but the binary compiled on the 
latest 3.7 branch works fine. Unfortunately, I can't compile tcl 8.6.8 after 
several tries. I think the test was added after the release of 3.7.0 is made 
thus causing failure on the released binary but works fine with the compiled 
one. If the above is correct then the test will also fail with latest 3.6.6 
release.

[issue34115] code.InteractiveConsole.interact() closes stdin

[Yonatan Zunger]

Yonatan Zunger  added the comment:

Definitely agree about the difference.

I'd say that either SystemExit or EOFError would be a reasonable thing for
the interactive session to do, but the combination of closing stdin and
SystemExit is really weird. Honestly, I would have just expected interact()
to return like an ordinary function when it was done; the logic of "it's
time to close the terminal window" feels like it belongs at a *much* higher
level of the stack.

[issue34178] test_tcl fails on the 3.7 branch

[Matthias Klose]

Matthias Klose  added the comment:

this is the python3.7 build for Debian, so yes, installed via a package manager 
;) 

see
https://ci.debian.net/data/packages/unstable/amd64/p/python3.7/
for the test results.

and yes, that seems to be a regression compared to the 3.7.0 release.

[issue34180] bool(Q) always return True for a priority queue Q

[Raymond Hettinger]

Raymond Hettinger  added the comment:

The class is not documented to support __len__() or __bool__(), so this is not 
a bug.  There is an empty() method provided for the purposes of testing whether 
a queue is empty or not.  Likewise, there is a qsize() method for determining 
the current size.

Note, these methods have a built in race condition -- the information may be 
out of date by the time it is used.  In general, an EAFP approach is preferred 
for reliable behavior (i.e. call get() in a try/except to see whether an Empty 
exception is raised).

FWIW, this module's API was designed by Guido a long time ago.  Presumably, he 
had his reasons for choosing empty(), full(), and qsize() over the __len__() 
method.  Once the API has been published and then become widely used, the time 
for debating his API decisions is over and we work with it as published.

[issue34178] test_tcl fails on the 3.7 branch

[Karthikeyan Singaravelan]

Karthikeyan Singaravelan  added the comment:

Got it. Thanks for the details. I understand the change in behavior since it 
was added as part of https://bugs.python.org/issue33974 after 3.7.0 but I don't 
know if this should be classified as a regression or as a bug fix after a 
stable release. This was merged to master, 3.7, 3.6 and 2.7 branches. 
https://bugs.python.org/issue33974#msg320663 also states that it needs a more  
a complex fix. I don't know the policy and I will leave it to @serhiy.storchaka 
to decide if it's a regression or a bug fix.

Thanks

[issue34186] [3.6.6 on macOS] os.listdir replacing "/" with ":"

[Todd]

New submission from Todd :

Short back story - I am organizing music where "/" appears in a lot a metadata 
for the songs. For instance, the artist "AC/DC" or "ACDC w/ Axl Rose". On 
macOS, it is acceptable to name a folder "AC/DC" while the slash would cause an 
issue in Windows.

Issue - While using os.listdir to list a number of artist folders inside my 
iTunes music folder os.listdir replaced "/" with ":" IF the "/" appears in the 
name itself. It does not replace the slash delimiters. 

I have included a screen shot. On the right side of the image is an example 
directory I made with a few folders. Two of the folders have "/" in their 
names.  On the left side of the image is the Python shell showing the use of 
os.listdir along with the output. You'll notice that the listed directories 
don't include "/", but instead include ":".

[issue34186] [3.6.6 on macOS] os.listdir replacing "/" with ":"

[Zachary Ware]

Zachary Ware  added the comment:

That's nothing to do with Python and everything to do with macOS.  As a test, 
open Terminal, do `ls ~/Example`, and you'll see `AC:DC` instead of `AC/DC`.  
As a further test, do `mkdir ~/Example/dir:with:colons` and then have a look in 
Finder.

See here [1] for more information.

[Berker Peksag]

Berker Peksag  added the comment:

I just noticed the same bug described by Éric in msg127840. PR 8390 should fix 
it. Unfortunately, it wasn't easy to create a test case, so I skipped that 
part. I'm open to suggestions if you have an idea on how to write a simple test 
that reproduces the bug.

Éric, could you confirm that the attached PR fixes the bug?

[issue21446] Update reload fixer to use importlib instead of imp

Berker Peksag  added the comment:

Thanks, Brett. I've opened PR 8391. Should we backport this to 3.7? We do 
backport mimetypes additions (see 
https://github.com/python/cpython/commit/8204b903683f9e0f037ccfaa87622716019914d7
 for an example) I think lib2to3 falls into the same category as mimetypes and 
it might be better to keep fixers in sync at least in 3.7 and 3.8.
