[issue33725] High Sierra hang when using multi-processing

[Ronald Oussoren]

Ronald Oussoren  added the comment:

Antoine, the issue is not necessarily related to POSIX compliance, AFAIK 
strictly POSIX compliant code should work just fine. The problem is in 
higher-level APIs (CoreFoundation, Foundation, AppKit, ...), and appears to be 
related to using multi-threading in those libraries without spending effort on 
pre/post fork handlers to ensure that new processes are in a sane state after 
fork().  In older macOS versions this could result in hard to debug issues, in 
newer versions APIs seem to guard against this by aborting when the detect that 
the pid changed.

Anyways... I agree that we shouldn't try to work around this in CPython, 
there's bound to more problems that are hidden with the proposed workaround.

---


 describes what the environment variable does, and this "just" changes behavior 
of the ObjC runtime, and doesn't make using macOS system frameworks after a 
fork saver.

[issue33725] High Sierra hang when using multi-processing

[Ronald Oussoren]

Ronald Oussoren  added the comment:

@Ned: In the long run the macOS installers should be build using the latest 
SDK, primarily to get full API coverage and access to all system APIs.

AFAIK building using the macOS 10.9 SDK still excludes a number of libSystem 
APIs that would be made available through the posix module when building with a 
newer SDK. 

That's something that would require some effort though to ensure that the 
resulting binary still works on older versions of macOS (basically similar to 
the work I've done in the post to weak link some other symbols in the posix 
module).

[issue33745] 3.7.0b5 changes the line number of empty functions with docstrings

[Ned Batchelder]

New submission from Ned Batchelder :

I'm not sure if this is a regression or an intentional change.  I know that the 
behavior has changed.

If a function has a docstring but no other body, Python 3.7b5 assigns the line 
number of the docstring to the implicit "return None".  Previous versions 
(including 3.7b4) used the line number of the "def".

Demonstration:

$ cat /tmp/empty.py
def empty():
pass

def empty_with_docstring():
'''Docstring'''

def docstring():
'''Docstring'''
return 1

import dis, sys

print(sys.version)

for fn in [empty, empty_with_docstring, docstring]:
print(fn.__name__)
dis.dis(fn)

[issue33749] pdb.Pdb constructor stdout override required to disable use_rawinput

[Michiel]

New submission from Michiel :

It looks like there's possibly a typo/small bug in the pdb.Pdb code. If I 
supply the stdin argument to the constructor, and provide e.g. a io.StringIO 
object, then I expect commands to be read from there. This however doesn't 
happen. If I additionally supply a stdout argument, then it works.

This is because use_rawinput is only disabled if stdout is specified, see 
https://github.com/python/cpython/blob/3.7/Lib/pdb.py#L144:

...
def __init__(self, completekey='tab', stdin=None, stdout=None, skip=None,
 nosigint=False, readrc=True):
bdb.Bdb.__init__(self, skip=skip)
cmd.Cmd.__init__(self, completekey, stdin, stdout)
if stdout:
self.use_rawinput = 0
...

I think it should be disabled if stdin is supplied, or possibly if either is 
specified (I'm not sure).

Repro:

import pdb
import io
pdb_script = io.StringIO("p 'hello';; c")
output = io.StringIO()

Buggy behaviour:

In [5]: pdb.Pdb(stdin=pdb_script).set_trace()
--Call--
> /usr/lib/python3.6/site-packages/IPython/core/displayhook.py(247)__call__()
-> def __call__(self, result=None):
(Pdb) c

Expected behaviour:

(Pdb) 'hello'

Working if stdout is supplied:

In [6]: pdb_script.seek(0)
Out[6]: 0

In [7]: pdb.Pdb(stdin=pdb_script, stdout=output).set_trace()

In [8]: print(output.getvalue())
--Call--
> /usr/lib/python3.6/site-packages/IPython/core/displayhook.py(247)__call__()
-> def __call__(self, result=None):
(Pdb) 'hello'


I would've had a go at fixing this, but even after reading the docs at 
https://docs.python.org/3/library/cmd.html#cmd.Cmd.use_rawinput it's not 
entirely obvious to me which combinations of stdin/stdout overrides should be 
valid and when use_rawinput should be set to 0. However, I'm pretty sure it 
should at least be set to 0 if stdin is supplied, which currently isn't the 
case.

[issue33750] Failed separate test_from_tuple in test_decimal

Stefan Krah  added the comment:

I think the tests are order-dependent in multiple places.  Personally, I don't 
see much value in fixing that because it has little effect on the actual code.

[issue33754] f-strings should be part of the Grammar

[David Halter]

New submission from David Halter :

Currently f-strings are a bit of a hack. They certainly work very well for 
users, but they are implemented in ast.c and therefore not part of the Python 
grammar and the tokenizer.

I want to change this. I wrote an alternative implementation of f-strings in 
parso (http://parso.readthedocs.io/en/latest/). The idea I have is to modify 
the Python grammar slightly 
(https://github.com/davidhalter/parso/blob/master/parso/python/grammar37.txt#L149):

fstring: FSTRING_START fstring_content* FSTRING_END
fstring_content: FSTRING_STRING | fstring_expr
fstring_conversion: '!' NAME
fstring_expr: '{' testlist [ fstring_conversion ] [ fstring_format_spec ] '}'
fstring_format_spec: ':' fstring_content*

We would push most of the hard work to the tokenizer. This obviously means that 
we have to add a lot of code there. I wrote a tokenizer in Python for parso 
here: in 
https://github.com/davidhalter/parso/blob/master/parso/python/tokenize.py. It 
is definitely working well. The biggest difference to the current tokenizer.c 
is that you have to work with stacks and be way more context-sensitive.

There were attempts to change the Grammar of f-strings like 
https://www.python.org/dev/peps/pep-0536/. It hasn't caught on, because it 
tried to change the semantics of f-strings. The implementation in parso has not 
changed the semantics of f-strings.

In a first step I would like to get this working for CPython and not 
tokenize.py. Modifying tokenize.py will not be part of my initial work here.

I have discussed this with Łukasz Langa, so if you guys have no objections I 
will start working on it. Please let me know if you support this or not.

[issue33750] Failed separate test_from_tuple in test_decimal

[Serhiy Storchaka]

Serhiy Storchaka  added the comment:

Doesn't this mean that the test is incorrect? It expects the result be 
'-0E-126', but actually it should be '-0E-107', and it is '-0E-126' 
only after performing some actions outside of the test. Or maybe that there is 
a leak of the state out of localcontext?

[issue33750] Failed separate test_from_tuple in test_decimal

[Stefan Krah]

Stefan Krah  added the comment:

The test is insignificant. The real tests are mpdecimal-testit- 2.4.1.tar.gz 
(http://www.bytereef.org/mpdecimal/download.html), deccheck.py and my private 
python test suite.

This test uses the global context that has been modified somewhere. I think I 
added that test to increase code coverage.

[issue33754] f-strings should be part of the Grammar

[Eric V. Smith]

Eric V. Smith  added the comment:

What is the goal here? Are you just trying to simplify ast.c?

My concern is that there are many, many edge cases, and that you'll be 
unknowingly changing the behavior of f-strings.

One of the goals of the f-string specification is for a simple third-party 
parser to be able to lexically recognize f-strings just like normal, raw, or 
byte strings. It should require no change to such a lexer except for adding "f" 
where "b", "r", or "u" is currently allowed. I do not want to break that design 
principle. There are plenty of examples in the wild where this design was 
leveraged.

[issue33754] f-strings should be part of the Grammar

[David Halter]

David Halter  added the comment:

As I wrote before, I'm not trying to change anything about the f-string 
behavior. It is a refactoring. If anyone wants to change the behavior, I feel 
like they should probably write a PEP anyway.

I personally don't like that f-strings get parsed multiple times. It just 
smells bad. Also f-strings are IMO not just strings. They should maybe look 
like strings for other tools to parse them. But they are more or less 
statements that get executed.

The code in ast.c is not bad. Don't get me wrong. I just think that it's the 
wrong approach.

Regarding the edge cases: I don't think there are that many. In the end the ast 
output will look similar anyway. All the backslashes, string literals and 
comments can be checked and rejected in the tokenizer already.

[issue33610] IDLE: Make multiple improvements to CodeContext

[Terry J. Reedy]

Terry J. Reedy  added the comment:

After writing the above, I realized that line scroll only touches editor.py, 
not codecontext.py.  On the other hand, the next item, 8. jump to context line 
did have to wait.  Replacing Label with Text will require explicit height 
setting with each context change.  The click handler will be a simplified 
version of the scroll handler you just wrote.  Jumping to a line will look much 
better when it jumps to a whole rather than a fractional line.  Again, one of 
us should say something before starting.

[issue33750] Failed separate test_from_tuple in test_decimal

[Stefan Krah]

Stefan Krah  added the comment:

The thread local context was modified in test_round(), so prec=28 was used in 
test_from_tuple() when running the whole test suite but prec=9 when running the 
single test.

I don't really consider that a bug, but it is easy to "fix".

I wouldn't be surprised if other similar cases exist.

[issue33755] Failed separate tests in test_importlib

[Serhiy Storchaka]

Serhiy Storchaka  added the comment:

Tests are passed if run the whole test_importlib. They are failed only when run 
the test_resource subset of them. This means that test_resource tests depend on 
the global environment changed by other tests. And this also means that some 
changes of the global environment are leaked from some tests, and may affect 
also other tests.

[issue33762] temp file isn't IOBase

[Dutcho]

New submission from Dutcho :

I'd expect isinstance(tempfile.TemporaryFile(), io.IOBase) to be True as you 
can read() from and write() to the temp file.

However, on Python 3.6.5 64 bit on Windows 7 above isinstance() == False and 
and type(tempfile.TemporaryFile()) == tempfile._TemporaryFileWrapper, which has 
no super class (other than object).
Whereas, on Python 3.6.1 on iOS 11.4 (Pythonista 3.2) above isinstance() == 
True and type(tempfile.TemporaryFile()) == io.BufferedRandom, which has 
io.IOBase as its (indirect) super class.
The difference is likely caused by tempfile line 565 that equals TemporaryFile 
= NamedTemporaryFile in case of Windows.

This may be somewhat related to issue 26175, but isn't a duplicate as 26175 is 
on a temp file's attributes, and this issue is on its type

[issue33713] memoryview can set an exception in tp_clear

[Stefan Krah]

Stefan Krah  added the comment:

Okay that makes sense. :)

I looked a bit at the gc code. A consumer object always has one
reference to a memoryview with an export, which isn't visited. So
it looks to me that the gc_refs of that memoryview cannot fall to 0.

So memory_clear() isn't called in that case, but mbuf_clear() is, which
is known and expected to handle mbuf->exports >= 0.

Indeed let's perhaps just add "if (self->exports > 0) return 0" to 
memory_clear() if those assumptions are too complex.

[issue33749] pdb.Pdb constructor stdout override required to disable use_rawinput

[R. David Murray]

R. David Murray  added the comment:

This is a duplicate of 2571 and 10396.  As I commented in 10396, if you want to 
work on an enhancement request (for cmd) that improves the situation, it will 
be welcome; but as you observed what to do isn't immediately obvious, so 
discussion before implementation is probably a good idea.  I'm going to close 
this, but feel free to open an enhancement issue with a proposal.

[issue33765] AppVeyor didn't start on my PR 7365

[STINNER Victor]

New submission from STINNER Victor :

I created the PR 7365:
https://github.com/python/cpython/pull/7365

AppVeyor job is required to pass to allow me to merge my PR. But AppVeyor job 
didn't start: 

"continuous-integration/appveyor/pr Expected — Waiting for status to be 
reported"

I cannot find any job related to my PR in the AppVeyor history:
https://ci.appveyor.com/project/python/cpython/history

The latest build was 5 hours ago.
