[issue32118] Doc for comparison of sequences with non-orderable elements

[Dubslow]

Dubslow  added the comment:

I like Terry's suggestion much better. I've closed my GitHub PR in favor of 
Terry's change.

My only suggested tweak might be throwing in something like "(e.g." None)", 
perhaps e.g. "Instances of an unordered class (e.g. None) become ordered...", 
but even as is, is a major improvement over mine. Thanks.

[issue31380] test_undecodable_filename() in Lib/test/test_httpservers.py broken on APFS

[Ned Deily]

Ned Deily  added the comment:

More background: APFS became available in macOS 10.12 although not used by 
default.  But with the current macOS 10.13 (High Sierra), root file systems on 
certain devices, such as SSDs, are automatically migrated from HFS+ to APFS so 
are much more likely to be seen starting in 10.13 and, in general, there is no 
easy way of knowing what type of FS a particular file resides on.

Thanks.  There was no way to predict the failures, but I thought that it could 
happen.  I think at this point the only proper fix is to remove the bitmask 
test.  I’ll work up a follow-on branch and port that back to 2.7 and 3.6.

[Abhilash Raj]

I understand that the line endings are meant for "outputs", but what 
constitutes as output in this case?

I now see that `EmailMessage.as_string()` gives me `\r\n` as line endings and, 
which is probably what you mean by output and `get_content()` given me internal 
representation of the Email's content?

"Now that blurb is there too, the logic for checking what is and isn't already

Yeah, it is a bit complicated.  There's also the issue of trying to use a make 
recipe to ensure a "venv" exists and is up-to-date.  I don't necessarily want 
to abandon the idea (and sorry I wasn't around to review the proposed change 
initially) but let's at least hold off until 370a3 is out the door.

[issue10544] yield expression inside generator expression does nothing

[Nick Coghlan]

Nick Coghlan  added the comment:

As far as I'm aware, there's nothing that specifically promises these 
constructs will do anything in Py3 at all - the existing behaviour is just an 
accident of implementation arising from the way nested scopes and yield 
expressions interact in general.

Tinkering with "await" in comprehensions and generator expressions would be 
different, since PEP 530 actually does make promises about how we expect that 
to work.

[issue30487] DOC: automatically create a venv and install Sphinx when running make

[Caleb Hattingh]

Caleb Hattingh  added the comment:

It looks like the check for an existing sphinx-build passes, and so no new venv 
is made, but this also means that blurb doesn't get installed.  I was concerned 
about this, but figured that at least the buildbots would create new envs each 
time, and this would only be an issue that a user with an odd configuration 
might have.

Sorry for the trouble.

The feature was simpler when it was only sphinx.  Now that blurb is there too, 
the logic for checking what is and isn't already present becomes a bit complex 
to reason through.

[issue32144] email.policy.SMTP and SMTPUTF8 doesn't honor linesep's value

[R. David Murray]

R. David Murray  added the comment:

Your are reading the documentation wrong.  For linesep, it says "The string to 
be used to terminate lines in serialized output."  The key word there is 
"output".  email operates in "universal newline mode" when parsing messages, 
turning all line endings into python's internal \n format.  What the linesep 
policy controls is the *output* line separator.

Note that the python2 behavior for decode=True is arguably a bug, but not one 
we are going to fix for backward compatibility reasons.

Those are all locally administered MAC addresses.  Does that mean some of the 
buildbot machines also have no universally administered MAC address, like 
Travis?  Or is something wrong with our logic?

If it’s the former, then it might just make better sense to remove the 42nd bit 
test in all cases.

Oh, without the preferential return of the universally administered MAC, you’re 
right.  So we should just remove the check for the 41st bit and not add the 
check for the 42nd bit.

No worries at all.  Thanks for working with me to make the fix as good as it 
can be.

I don’t mind, but interestingly enough, test_uuid does not fail for me locally 
in either the 2.7 or 3.6 branches!  I don’t know what’s different, since I’m 
running them on exactly the same machine, but that does seem to be the case.

Still, I think it makes sense to backport the change in check, without 
backporting the feature change or code cleanups, so I’ll work on branches for 
those.

[issue32149] bolen-dmg-3.x: compiled failed with: blurb: command not found

[David Bolen]

David Bolen  added the comment:

Yeah, I'm not sure if I can do anything on my side.  It looks like it's  an 
issue with the build patch (issue30487, commit d8d6b91, assuming that's what 
Zachary is referring to).  The blurb complaint is about something that appears 
should have been installed in a venv during the build process.  

If I need to upgrade or install something on the worker to support this change, 
I can certainly do that, but I don't immediately see what that should be.

[issue32150] Expand tabs to spaces in C files

[Serhiy Storchaka]

Serhiy Storchaka  added the comment:

Tools/scripts/patchcheck.py does this check. It is used for .py and .rst files, 
and there is issue8912 for applying it to .c/.h files.

patchcheck.py also checks trailing whitespaces. While I and other core 
developers constantly remove trailing whitespaces (the recent clean up is PR 
4130), the new trailing whitespaces are constantly added (for example in PR 
4150).

[issue32151] -mvenv vs minor python version updates

[Ric Anderson]

New submission from Ric Anderson :

When a site updates python3 from 3.5 to 3.6 (based on 
https://docs.python.org/3/faq/general.html#how-does-the-python-version-numbering-scheme-work,
 this is would be a minor version update),pre-upgrade venv setups created with 
"python3 -menv ..." break because "python3" in the venv is really 3.5, and 
needs the system libpython3.5m.so.1.0, which is no longer in the library search 
list.

Should "python -mvenv ..." copy the libpython3.5m.so.1.0 to the venv 
directory/lib, or add the system path to libpython3.5m.so.1.0 to 
LD_LIBRARY_PATH, or should the minor version number (.5 ,or .6) be excluded 
from the library name, so that minor version updates don't break existing venv 
setups or ???

[issue32150] Expand tabs to spaces in C files

[Serhiy Storchaka]

New submission from Serhiy Storchaka :

While most C files use spaces for indenting and aligning, there are few sites 
in which tabs are left. Sometimes mixed tabs and spaces are used in the same 
file.

This adds a noise in the diff if the committer uses an editor which doesn't 
preserve tabs (see for example PR 4390). This can hide semantic changes in tab 
expansion changes.

I reviewed many patches with accidentally expanded tabs to spaces. Usually I 
request removing unrelated changes from the patch. But this still happened, and 
tabs slowly are disappeared from the sources. There are less tabs in the 
current default branch than in any maintained branch.

I think it is better to make the expansion in a single not so large commit that 
allow them be mixed with semantical changes. PR 4583 does this. The changes 
first were made automatically, and after that I have edited them manually for 
removing excessive indentations in some files (4 spaces are enough). Tabs have 
been kept only in generated file Modules/unicodedata_db.h and in imported files 
Modules/_ctypes/* and Modules/expat/siphash.h.

[issue10544] yield expression inside generator expression does nothing

[Guido van Rossum]

Guido van Rossum  added the comment:

After the tiresome debate I am happy to see this just as a "what's new" entry 
rather than soliciting more debate with a PEP. (However there may be some 
existing PEP that suggests it should work? That PEP should be amended with a 
note that this is being deprecated. But I don't know if there is such a PEP.)

There are certainly computers that have both universal and local admin MAC 
addresses, as proven by the MBP+TouchBar case that triggered this.  I don’t 
know whether we can assume anything about the order in which those are 
enumerated.

[issue32071] Add py.test-like "-k" test selection to unittest

[Jonas H.]

Jonas H.  added the comment:

Ah, the problem isn't that it's running getattr() on test methods, but that it 
runs getattr() on all methods.

Former code: attrname.startswith(prefix) and \
callable(getattr(testCaseClass, attrname))

New code: testFunc = getattr(testCaseClass, attrname)
isTestMethod = attrname.startswith(self.testMethodPrefix) and 
callable(testFunc)

This is trivial to fix. @Core devs: Should I revert to original behaviour with 
the order of the prefix check and the getattr() call, and add a regression test 
that guarantees this behaviour?

Serhiy: "Could you please make a benchmark for warnings emitted in a tight loop 
in the C code. It would be nice to know what is the worst case. If it is less 
than 2x slower I will prefer this simpler PR."

I merged my PR since it's not 2x slower. I also prefer the simple PR 4489, 
rather than the complex PR 4502.

I rejected my PR 4502 since it's backward incompatible. I don't think that it's 
worth it, even if it's faster.

[issue32071] Add py.test-like "-k" test selection to unittest

[Tim Graham]

Tim Graham  added the comment:

This is appearing as a backwards incompatible change for Django because test 
case class attributes are now evaluated at load time before setUpClass runs 
(which initializes some things that those class attributes use). It's possible 
to adapt Django for this change, but it might affect other projects as well.

[issue27035] Cannot set exit code in atexit callback

[Torsten Landschoff]

Torsten Landschoff  added the comment:

As this bug report clearly states this worked as documented in Python 2.7 and 
stopped working sometime in the Python 3 series.

I just ran into this while porting some code to Python 3 which uses an atexit 
handler to wind down some resources on process exit. This sometimes gets stuck 
and instead of hanging indefinitely the cleanup is aborted if it takes longer 
than a few seconds.

As this is actually an error, the registered exit function raises SystemExit to 
modify the exit code in this case. This used to work fine but does not 
anymore...

Observe:


## Python 2.7 works fine

$ sudo docker run python:2.7 python -c "import 
atexit,sys;atexit.register(sys.exit,124)"; echo $?
124

## Python 3.2 (oldest Python 3 on docker hub) swallows the exit code (but 
prints it)

$ sudo docker run python:3.2 python -c "import 
atexit,sys;atexit.register(sys.exit,124)"; echo $?
Error in atexit._run_exitfuncs:
SystemExit: 124
0

## Same for 3.3 up to 3.6

$ sudo docker run python:3.3 python -c "import 
atexit,sys;atexit.register(sys.exit,124)"; echo $?
Error in atexit._run_exitfuncs:
SystemExit: 124
0
$ sudo docker run python:3.5 python -c "import 
atexit,sys;atexit.register(sys.exit,124)"; echo $?
Error in atexit._run_exitfuncs:
SystemExit: 124
0

$ sudo docker run python:3.6 python -c "import 
atexit,sys;atexit.register(sys.exit,124)"; echo $?
Error in atexit._run_exitfuncs:
SystemExit: 124
0

## Python 3.7 swallows the exit code *and does not even print it*:

$ /opt/python-dev/bin/python3.7 -c "import 
atexit,sys;atexit.register(sys.exit,124)"; echo $?
0

[issue10544] yield expression inside generator expression does nothing

[Serhiy Storchaka]

Serhiy Storchaka  added the comment:

Note that the DeprecationWarning exception is replaced with a SyntaxError to 
get a more accurate error report.

$ cat yield-gen.py 
def f():
return ((yield x) for x in range(3))

$ ./python -Wd yield-gen.py
yield-gen.py:2: DeprecationWarning: 'yield' inside generator expression
  return ((yield x) for x in range(3))

$ ./python -We yield-gen.py
  File "yield-gen.py", line 2
return ((yield x) for x in range(3))
   ^
SyntaxError: 'yield' inside generator expression


Without this replacement the result would be:

$ ./python -We yield-gen.py
DeprecationWarning: 'yield' inside generator expression

[issue32089] In developer mode (-X dev), ResourceWarning is only emited once per line numbers

[STINNER Victor]

STINNER Victor  added the comment:

The "default warning filters" are documented, but only for Python compiled in 
release mode:
https://docs.python.org/dev/library/warnings.html#default-warning-filters

So I didn't touch this documentation.

The initial issue is now fixed: the development mode (-X dev) now behaves as 
the debug mode (pydebug build) for the default warning filters.

The second issue, Antoine's complain about the "always" action, was also fixed.

I close the issue. At the end, we should get a better debug experience ;-)

[issue32146] multiprocessing freeze_support needed outside win32

[Daniel Colascione]

New submission from Daniel Colascione :

multiprocessing's freeze_support makes freshly-launched subprocesses integrate 
correctly until the multiprocessing ecosystem even when the main executable is 
some application binary instead of a Python interpreter. The documentation and 
code assume that this support is needed only on win32, but it's equally 
applicable to POSIX systems using the spawn strategy in combination with 
systems like cx_freeze.

In particular:

1) The special case in context.py's version of freeze_support() for win32 
should be removed

2) The semaphore tracker should correctly tickle the freeze support

3) The documentation should be updated to be platform-neutral

[issue32145] Wrong ExitStack Callback recipe

[Maurizio Zucchelli]

New submission from Maurizio Zucchelli :

The documentation for contextlib.ExitStack 
(https://docs.python.org/3.7/library/contextlib.html#replacing-any-use-of-try-finally-and-flag-variables)
 shows an helper class (Callback) to perform cleanup using a callback.
Problem is, Callback.cancel() calls ExitStack.pop_all(), which in turn calls 
type(self)(), this is not a valid constructor for Callback, since it always 
expects at least one element.

(I have marked only Python 3.4 and 3.6 since those are the versions where I 
verified this, but it likely applies to every version.)
