I can't reproduce the failure in anyway. :-( Could you do some investigation

[issue29290] argparse breaks long lines on NO-BREAK SPACE

[wim glenn]

wim glenn added the comment:

The test "test_help_non_breaking_spaces" from Zhang's commit fails on my 
platform (other 1563 tests in the module all pass).  

Interestingly, if running the entire test suite, it doesn't fail.  It's only 
when executing the test_argparse.py module directly that causes the failure.

I guess there is some mutable state, or the test doesn't entirely setup 
correctly.

[issue30230] Move quick test in PyObject_IsSubClass outside of PyType_CheckExact guard

[Jim Fasarakis-Hilliard]

Jim Fasarakis-Hilliard added the comment:

> he said, "I'm not sure if this was placed inside there due to some wild 
> edge-case,"

As a new contributor, I'll always lean on the side of me not seeing something 
rather than confidently stating that something is definitely wrong. I'm new, 
the code-base is 20 years old and worked on by a dozen of experienced devs :-)

>  Does a "Not-A-Class" class which is not a subclass of itself (issubclass(C, 
> C) returns False) makes any sense?

I'm not sure. Apart from the performance impact, there's a behavioral 
discrepancy between isinstance and issubclass as you also stated. 

In isinstance, __instancecheck__ doesn't *always* get a chance to override the 
behavior. The `if type(inst) == Cls` [1] stops it before it gets a chance. 
In issubclass, __subclasscheck__ does override it:

class Meta(type):
def __instancecheck__(self, other):
print("invoked")
return False
def __subclasscheck__(self, other):
print("invoked")
return False

class Cls(metaclass=Meta):
pass

isinstance(Cls(), Cls)
True

issubclass(Cls, Cls)
invoked
False

So, I guess the question might be re-framed to: Is it guaranteed that 
__instancecheck__ and __subclasscheck__ are *always* called?

If yes: PyObject_IsInstance should be tweaked.
If no:  PyObject_IsSubclass should be tweaked.

p.s Should I maybe move this to python-dev?

It's already part of aiosmtpd although not with the small amount of
generic-ness included here.  It's been useful and stable.  So this is just
refactoring out the aiosmtpd-ness of it.  It doesn't seem big enough to put
into yet another separate library.

[issue30219] webbrowser.open outputs xdg-open deprecation warning

I don't think that always hiding output for any browser is a good idea.

xdg-open is supposed to be cross-desktop (GNOME, XFCE, KDE, etc.).

Maybe a better fix is to use "gio" if available, or fallback on xdg-open 
otherwise? But gio is specific to GNOME no? What if the user has GNOME and KDE 
installed?

[issue30338] LC_ALL=en_US + io.open() => LookupError: (osx)

[STINNER Victor]

STINNER Victor added the comment:

> It may be an OSX specific bug?

Yes, on Linux, it "just works":

haypo@selma$ LC_ALL=en_US python2 -c 'import io; io.open("/dev/null")'
haypo@selma$ LC_ALL=en_USxxx python2 -c 'import io; io.open("/dev/null")'

In fact, you get ASCII encoding for these two locales:

haypo@selma$ LC_ALL=en_US python2 -c 'import locale; 
print(locale.getpreferredencoding(False))'
ANSI_X3.4-1968

haypo@selma$ LC_ALL=en_USxxx python2 -c 'import locale; 
print(locale.getpreferredencoding(False))'
ANSI_X3.4-1968

Internally, io.open() uses locale.getpreferredencoding(False) if you don't 
specify an encoding.

While I run Linux and have Windows and FreeBSD VM, sometimes I'm lazy and rely 
on the CI. I consider that it's waste to burn CI CPUs sometimes :-) For 
example, it's not that easy to test a change specific to Windows on Python 2.7, 
but AppVeyor now runs tests for you!

[issue9850] obsolete macpath module dangerously broken and should be removed

[STINNER Victor]

STINNER Victor added the comment:

> Bump, any update on what to do with this issue?

I updated and completed Chi Hsuan Yen's 3.6-deprecate-macpath.patch to create a 
pull request. I suggest to start by deprecating macpath in 3.7, and remove it 
from Python 3.8.

This module is here for years. macOS 9 is now dead, all macOS users migrated to 
OS X nowadays. I don't think that there is an urgency to *remove* macpath.

The title says "obsolete macpath module dangerously broken": is "dangerous" 
still up to date after the following fix?

New changeset 54987723de99 by Serhiy Storchaka in branch '3.4':
Issue #9850: Fixed macpath.join() for empty first component.  Patch by
https://hg.python.org/cpython/rev/54987723de99

If yes, we may also warn users in the macpath documentation that the module is 
dangerous, especially in the documentation of Python < 3.7.

[issue30338] LC_ALL=en_US + io.open() => LookupError: (osx)

[Anthony Sottile]

New submission from Anthony Sottile:

Originally seen here: https://github.com/Microsoft/vscode/issues/26227

```
$ LC_ALL=en_US python -c 'import io; io.open("/dev/null")'
Traceback (most recent call last):
  File "", line 1, in 
LookupError: unknown encoding: 
```

Admittedly, that `LC_ALL` looks malformed (should be en_US.UTF-8), but given 
this works on linux:

```
$ env -i LC_ALL=en_US python -c 'import io; io.open("/dev/null")'
$
```

It may be an OSX specific bug?

I've only tagged py27 + py36 because I did not have a build toolchain available 
to try on master, though I imagine it is reproducible there as well.

[issue30337] Vague wording of pkgutil.walk_packages parameter 'prefix'

[Sam Silberstein]

New submission from Sam Silberstein:

Hi there! 

This is my first submission to the bug tracker, so I apologize if I'm missing 
some formatting here.

I've found what's either vague documentation for the 'prefix' parameter of 
`pgkutil.walk_packages` or a bug. The method implies that it will only import 
submodules of the provided path, but if the prefix parameter is not filled, 
this method will import a module with the same name from outside the path -- so 
long as it exists in `sys.modules`. I'm unsure if this is due to the 
documentation not specifying that prefix should always be used when path is 
set, or if this is a bug (I can provide a fix if it's a bug).

Steps to reproduce:

Create a directory with a nested package with the same name as a package 
outside that directory, e.g.:

|_ test1
  |_ __init__.py
  |_ should_not_be_included.py
|_ test2
  |_ test1
|_ __init__.py
|_ test1
  |_ __init__.py
  |_ should_be_included.py

`list(pkgutil.walk_packages('test2'))` will contain 'should_not_be_included.py' 
instead of 'should_be_included.py'.

Thank you!

Sam Silberstein

[issue29943] PySlice_GetIndicesEx change broke ABI in 3.5 and 3.6 branches

[Nathaniel Smith]

Nathaniel Smith added the comment:

@Jonathan: Even 3.6.1 was careful to retain compatibility with code built by 
3.6.0. And your proposed 3.6.1-patched will generate binaries equivalent to the 
ones 3.6.0 generates. So I don't think you need to worry; 3.6.2 is not going to 
add a new and worse compatibility break, which is what it would take for your 
proposal to cause a problem. In fact, your 3.6.1-patched is equivalent to what 
I think 3.6.2 should do. I say go for it; patching 3.6.1 seems like a good 
solution.

[issue25652] collections.UserString.__rmod__() raises NameError

[Jonathan Goble]

Jonathan Goble added the comment:

I would prefer to keep __rmod__ and fix the bug, given that the use case I 
described above would otherwise create an inconsistency in subclasses, which 
would be able to easily extend __mod__ by calling super(), but would be forced 
to fully implement __rmod__ themselves.

That said, I will defer to those who are more experienced here.

[issue30231] test_imaplib needs a TLS server accepting self-signed certificates

[Berker Peksag]

Berker Peksag added the comment:

> Is it to validate that we have bugs? :)

More or less, yes. Since the problem is not in the library code and the tests 
are not completely useless, using @unittest.expectedFailure might be a better 
short term solution than skipping or removing them (at least we are not going 
to forget them :))

Yet another alternative is to tweak test_logincapa_with_client_certfile to just 
check for DeprecationWarning. See 
https://github.com/python/cpython/pull/1419/files#r115050499 for details.

[issue30336] Pull Requests need more detail

[Brett Cannon]

Brett Cannon added the comment:

I'm not sure if this is going to be useful enough to force all contributors to 
deal with. Justification for a change should be on bugs.python.org and that's 
mentioned in the CONTRIBUTING.md guidelines. As for testing, the 
Travis/AppVeyor failures should communicate that. And for specifying the issue 
number, there's a status check for that to help communicate it.

I'll let other core devs comment, but while I appreciate what Jensen is trying 
to help with, I don't think the template helps enough to justify forcing every 
contributor to have to deal with it.

You can also bring this up on the core-workflow mailing list, Jensen, if you 
want to discuss it there.

[issue30335] Document deprecated alias of assertNotRegex

[Marco Buttu]

Marco Buttu added the comment:

Hi Jim, I think assertNotRegexpMatches has never been introduced:

https://docs.python.org/3/whatsnew/3.1.html
https://docs.python.org/3/whatsnew/3.2.html

That is why there is no reference in the documentation about that.  I also 
executed a test with Python 3.1 and 3.2. and I found that there is no 
assertNotRegexpMatches assertion available.

[issue30332] Errors that aren't actually defined are purple in the IDLE

[Terry J. Reedy]

Terry J. Reedy added the comment:

You neglected to say which version of Python you used.  2.7? 3.2? When I type 
the following in 3.5+ on Win10,
>>> IOError, KeyError, PermissionError, int, list, FileNotFoundError
all the names have the same builtins highlight.  In 2.7 (and early 3.x), 
PermissionError and FileNotFoundError did not exist as builtins and should not 
get the hightlight.

I don't understand the purpose of tests known to fail. Is it to validate that 
we have bugs? :)

[issue30320] test_eintr.test_sigwaitinfo(): race condition on AMD64 FreeBSD 10.x Shared 3.6

[STINNER Victor]

STINNER Victor added the comment:

The bug occurs randomly, since it's hard to say at this point if my change 
fixes it for real or not. I close the bug, but will reopen it if the bug occurs 
again.

But I'm confident that blocking the signal is "the right fix" for such unit 
test.

[issue30331] TestPOP3_TLSClass: socket.timeout: timed out on AMD64 FreeBSD 10.x Shared 3.x

[STINNER Victor]

STINNER Victor added the comment:

I don't understand the following error, since DummyPOP3Handler constructor 
(__init__) ends with "self.tls_starting = False".

AttributeError: 'DummyPOP3Handler' object has no attribute 'tls_starting'

Maybe self.handle_read() is called during asynchat.async_chat.__init__(self, 
conn)? Is that even possible?

[issue30319] test_invalid_authentication() of test_imaplib: ConnectionResetError: [Errno 54] Connection reset by peer on AMD64 FreeBSD 9.x 3.6

[STINNER Victor]

STINNER Victor added the comment:

@Our SSL experts: any idea why sock.close() fails with "ConnectionResetError: 
[Errno 54] Connection reset by peer" in imaplib? Is that a new error? Should 
imaplib catch ConnectionResetError on sock.close()?

By the way, see also bpo-30329: I proposed a patch to catch the Windows socket 
error 10022 on shutdown() for poplib and imaplib SSL connections. No idea why 
this error only occurs on SSL connections.

[issue29243] --enable-optimizations makes common build commands always need to compile from scratch

[Brett Cannon]

Brett Cannon added the comment:

To be honest, I'm not excited by ./configure --enable-optimizations. I was 
happy with an explicit "make profile-opt".

The configure flag was added because not everything can be enabled just in the 
Makefile and so that people have a single flag to set to turn on any and all 
optimizations that work consistently across OSs (it used to be LTO+PGO until we 
discovered how universally broken LTO seems to be).

[issue27144] concurrent.futures.as_completed() memory inefficiency

[Mark DePristo]

Mark DePristo added the comment:

Any update on this reviewing, patching, and then backporting to 2.7? We've just 
run into the exact same issue here in Google using a ThreadPoolExecutor.map 
call growing memory usage without bounds due to the Future holding onto its 
result even after being returned from the map call. There's a more specific 
patch possible for just map() itself, but this more general one seems like it'd 
be better.

[issue29943] PySlice_GetIndicesEx change broke ABI in 3.5 and 3.6 branches

[Jonathan Helmus]

Jonathan Helmus added the comment:

In Anaconda we ship both Python 3.6.0 and 3.6.1 and have run into this issue 
when building packages with 3.6.1 and importing them on 3.6.0.  We are 
discussing adding #undef PySlice_GetIndicesEx to the Python.h we ship with 
Python 3.6.1.  From the discussion here this seems like a possible solution but 
we are worried about ABI compatibility with future releases in the 3.6 branch.  
Is there a consensus on how this will be addressed in 3.6.2?

For a very generic "retry" library, see https://pypi.python.org/pypi/tenacity

But I don't think that we need such advanced library, a simple loop should do

[issue30334] [Windows] support.rmtree() should retry on WindowsError: [Error 32] The process cannot access the file because it is being used by another process

[STINNER Victor]

New submission from STINNER Victor:

test_startfile uses a weak time.sleep(0.1) to wait until the process started by 
os.startfile() completes. Instead of a sleep, can't support.rmtree() retry on 
"WindowsError: [Error 32] The process cannot access the file because it is 
being used by another process" error? For example, retry every 100 ms during 10 
seconds?

It's easy to reproduce the bug on Python 2.7: just remove the time.sleep() call 
in tests.

If it's too complex to implement a retry (too complex? really?), an obvious 
hack is to increase the sleep in test_startfile.py from 100 ms to 200 ms...

[Mariatta Wijaya]

Mariatta Wijaya added the comment:

Yes, PR 1535 is indeed linked to this issue, if you're reading it from the bug 
tracker.

The pull request number you see from the notification email (+1634) refers to 
the pull_request item in the bug tracker 
(https://bugs.python.org/pull_request1634).

This number is different than the pull request # on GitHub.

Hope this clarifies it :)

[issue30323] concurrent.futures.Executor.map() consumes all memory when big generators are used

[Xiang Zhang]

Xiang Zhang added the comment:

IIUC, the meaning of executor.map() is to run the tasks concurrently. So you 
have to loop the iterable ahead to submit all the tasks. If you make it a 
generator comprehension, you are actually submitting a task and then getting 
the result. So you are executing the tasks sequentially. Doesn't it violate the 
intention and meaning of executor.map()?

[issue16865] ctypes arrays >=2GB in length causes exception

[David Heffernan]

David Heffernan added the comment:

Erik,

As you can no doubt guess, this is related to the questions I have been asking 
on SO that you have so expertly been answering. Thank you!

When I solved the latest problem, getting at the internal buffer of a 
bytearray, I used the code in my previous comment, which came from a comment 
(now deleted) of yours to the question.

Looking at this more closely I realise that, as you said in your answer, the 
array length is not important for my specific needs, to it is fine to use zero. 
That side steps this issue completely. Thanks again.

[issue29243] --enable-optimizations makes common build commands always need to compile from scratch

[Tomas Orsava]

Tomas Orsava added the comment:

In addition, profile-opt would have to rewritten to test whether there's
already an interpreter built with PGO. And if there is, regenerate it only if
the main target is `all` or `profile-opt`, but not when someone runs `make
test`, `make install`, etc.

It's maybe too radical, but we could change it so that if you run `make test`, 
`make install` and the like and there's no interpreter built already to test or 
install, the user is told to run `make` first.

[issue16865] ctypes arrays >=2GB in length causes exception

[Eryk Sun]

Eryk Sun added the comment:

In older versions of ctypes, before it was added to the standard library, the 
underlying length field was a C int, and CArrayType_new used the PyInt_AS_LONG 
macro. ctypes was added to the standard library in 2.5, by which time the 
length field is Py_ssize_t, but CArrayType_new still used the PyInt_AS_LONG 
macro. That's still the case in 2.7. Python 3 changed this to call 
PyLong_AsLongAndOverflow, but apparently Christian Heimes didn't consider 
fixing this properly to use Py_ssize_t:

https://hg.python.org/cpython/rev/612d8dea7f6c

David, maybe there's a workaround for your use case, if you can provide some 
more details.

[issue29808] SyslogHandler: should not raise exception in constructor if connection fails

> How can this be true?

Perhaps it didn't make the cut for that specific release? Seems to be in the 
3.5 branch OK.

[issue29243] --enable-optimizations makes common build commands always need to compile from scratch

[STINNER Victor]

STINNER Victor added the comment:

Oh wait, I expected that "make test" would build Python with PGO, but it 
doesn't anymore. Would it be possible to change the Makefile to make sure that 
"make python" (on Linux, "make python.exe" on macOS) would build Python using 
PGO?

I tried to hack something, but I'm lost in dependencies... "make profile-opt" 
runs "$(MAKE) build_all_generate_profile" which runs "$(MAKE) build_all 
CFLAGS_NODIST=..." and build_all depends on "$(BUILDPYTHON)".

I'm not sure that it's possible to make everything automatic because of the 
high number of targets and dependencies.

To be honest, I'm not excited by ./configure --enable-optimizations. I was 
happy with an explicit "make profile-opt".
