[issue36520] Email header folded incorrectly

[Jeffrey Kintscher]

Jeffrey Kintscher  added the comment:

To aid with debugging the code, the Subject line can be simplified:

>>> from email.message import EmailMessage
>>> m = EmailMessage()
>>> m['Subject'] = 'Hello 
>>> =?utf-8?q?W=C3=B6rld!_Hello_W=C3=B6rld!_Hello_W=C3=B6rld!?= Hello 
>>> Wörld!Hello Wörld!'
>>> print(bytes(m))
b'Subject: Hello =?utf-8?q?W=C3=B6rld!_Hello_W=C3=B6rld!_Hello_W=C3=B6rld!?=\n 
Hello =?utf-8?=?utf-8?q?q=3FW=3DC3=3DB6rld!Hello=3F=3D_W=C3=B6rld!?=\n\n'

[issue37061] The strangest glitch I have ever seen - incorrect indenterror, even on commented out code.

[Tim Peters]

Tim Peters  added the comment:

Same kind of problem with the new upload, Bob.

Line 38 is:

print(Fore.GREEN,"Installed file ",e,Fore.WHITE)

indented 8 spaces. Lines 39 and 40 are empty.  Then line 41 is:

if x>=len(files):  # if x is more than or equal to the number of files in teh 
directory

indented 12 spaces.  That's an indentation error, indented more than the 
statement before it.

Maybe you have some kind of weird binary data (by mistake) in the file that 
gets lost when you upload it?

As Steven said, there's an obvious indentation error in the file you actually

If I increase the indentation of the `print` Steven identified to match the 
indentation of the `print` before it, IDLE's Run -> Check Module has no 
complaints.

Steven D'Aprano  added the comment:

Hi Bob, and welcome. Can you copy and paste the actual traceback or error you 
get? It isn't obvious from your description what the error is.

Just glancing at the attached sample code, I see what seems to be an obvious 
indentation error:

for _ in range(len(files)):
try:
e = files[x] # e = the file with a paramater of x
os.copy(e,"C:\\Windows\\System32") # copy the file to system32
except Exception as e:
print(Fore.RED,"Could not install file ",x,". The following error 
occurred: ",e,Fore.WHITE)
print(Fore.GREEN,"Installed file ",e,Fore.WHITE)
if x>=len(files):  # if x is more than or equal to the number of 
files in teh directory
print(Fore.GREEN,"Installed ",Fore.WHITE)


Notice that the "if" statement is indented under the print. Is that the cause 
of your error?

[issue37061] The strangest glitch I have ever seen - incorrect indenterror, even on commented out code.

[Bob Vegene]

New submission from Bob Vegene :

So, I'm making a simple program that will allow me to quickly copy programs to 
System32 for use on the command line. When I tried testing this in a file 
called test.py in the same directory as sys32move.py, I got a very strange 
error. IndentError. I am very experienced with python and I know how to fix 
this and why it is caused. I fixed what I thought I could, but the I realized 
something was off. 

I commented out everything in sys32move.py and it still outputs this error.

Now, commenting this out is unnecessary, as this is a false error anyway.


This is test.py:
try:
import sys32pack
install_folder(testfolder)
except Exception as e:
print(e)
input()

(you get same behavior without the catching of the error.)

[issue37060] import ctypes fails with a statically linked interpreter due to dlopen() failure

[Gregory Szorc]

New submission from Gregory Szorc :

ctypes/__init__.py calls _ctypes.dlopen(None) on Linux as part of code 
execution during module import. Unfortunately, dlopen() doesn't work if the 
current executable isn't a dynamic executable.

Using a fully statically linked Python executable:

$ ldd python3.7
not a dynamic executable

$ python3.7
>>> import _ctypes

>>> _ctypes.dlopen(None)
Traceback (most recent call last):
  File "", line 1, in 
OSError: Dynamic loading not supported

>>> import ctypes
Traceback (most recent call last):
  File "", line 1, in 
  File 
"/home/gps/src/python-build-standalone.git/build/python/install/lib/python3.7/ctypes/__init__.py",
 line 444, in 
pythonapi = PyDLL(None)
  File 
"/home/gps/src/python-build-standalone.git/build/python/install/lib/python3.7/ctypes/__init__.py",
 line 356, in __init__
self._handle = _dlopen(self._name, mode)
OSError: Dynamic loading not supported


I think it is a bug that `import ctypes` raises OSError at import time in this 
environment. I can make a compelling argument that this error should either be 
suppressed or converted to an ImportError.

Producing a fully statically linked Python executable is a bit of work and 
isn't easily accomplished with the existing build system. My 
"python-build-standalone" project automates the process. A fully statically 
linked Python executable is available in the zstd compressed archive at 
https://github.com/indygreg/python-build-standalone/releases/download/20190505/cpython-3.7.3-linux64-musl-20190526T0219.tar.zst
 under the python/install/bin/python3.7 path. Simply extract that archive and 
run that binary to reproduce.

[issue37011] pdb: restore original tracing function instead of sys.settrace(None)

>From my initial comment:

It will also affect running tests with coverage (in general, or using tools 
like pytest-testmon), and using pdb.set_trace then (either for debugging, or 
via post-mortem, e.g. pytest's `--pdb`).

[issue17005] Add a topological sort algorithm

[Pablo Galindo Salgado]

Pablo Galindo Salgado  added the comment:

> * allow input as ordered pairs like the Unix tsort command
> * allow more convenient input as dependency sequences (like graphviz):

This is how my first proposal started (and I still like it a bit more than the 
dictionary input), but there are some concerns (check other comments) regarding 
this API, like representing isolated nodes or disjoint graphs.

> return both the sorted sequence and cycles

Regarding the output, I like returning a collection of sets, where every set 
represents all possible elements of the same order in the result. This also 
helps if the user has some expectation regarding the ordering. For example, in:

['ABDGI', 'BEG', 'CEH', 'KCFHJ']

the results starting with

['A', 'B', 'D'

and

['A', 'B', 'K'

are both valid.

With the current implementation, this is the equivalent of C3 linearization:

  from itertools import tee
  from collections import defaultdict
  def c3_linearization(inheritance_seqs):
 graph = defaultdict(set)
 for seq in inheritance_seqs:
 a, b = tee(seq)
 next(b, None)
 for child, parent in zip(a,b):
 graph[child].add(parent)
 retun ((list(group) for group in functools.toposort(graph)), [])
 return tuple(reversed(order))

  >>> class A: pass
  >>> class B(A): pass
  >>> class C(A): pass
  >>> class D(B, C): pass

   >> D.__mro__
  (__main__.D, __main__.B, __main__.C, __main__.A, object)

   >> c3_linearization([(D, B, A, object), (D, C, A, object)])
  [{__main__.D}, {__main__.B, __main__.C}, {__main__.A}, {object}]

What do you think?

[issue17005] Add a topological sort algorithm

[Raymond Hettinger]

Raymond Hettinger  added the comment:

Attaching some of my 2013 work on this.  Here are some API notes:

* spell-out the name topological_sort()

* allow input as ordered pairs like the Unix tsort command
  https://en.wikipedia.org/wiki/Tsort#Examples

* allow more convenient input as dependency sequences (like graphviz):
 [['a', 'b', 'c', 'x], ['b', 'd', 'e', 'y']]
  is short for and equivalent to:
 [(a,b), (b,c), (c,x), (b,d), (d, e), (e, y)]

* return both the sorted sequence and cycles
  (both are individually useful and the latter
   is helpful in debugging in only the former is wanted)

* desire to match the C3 MRO computation


* would like the ordering to be stable and deterministic
  (this precludes picking arbitrary elements from sets).

[issue37058] Implement PEP 544: add Protocol to typing

[Ivan Levkivskyi]

New submission from Ivan Levkivskyi :

The implementation would be basically copying some code from `typing_extension` 
and fixing some important known issues (such as renaming @runtime to 
@runtime_checkable and allowing sub-protocols of builtin protocols). Also 
ideally we should get rid of the metaclass `_ProtocolMeta`.

[issue35753] Importing call from unittest.mock directly causes ValueError

[Karthikeyan Singaravelan]

Karthikeyan Singaravelan  added the comment:

> The actual bug appears to be "doctest can't run on a module that contains 
> un-unwrappable objects"

Is it the below example scenario being discussed in the issue? Since call is 
imported it's also present in obj.__dict__ and hence trying to unwrap it [0] 
could cause error.

This is also mentioned in https://bugs.python.org/issue25532#msg253885 against 
which this issue was closed. 

> This can occur when you use doctest.DocTestSuite to load doc tests from a 
> module where unittest.mock.call has been imported.

[issue37039] IDLE: Improve zoomheight doc and behavior.

[Terry J. Reedy]

Terry J. Reedy  added the comment:

When you start, it should say 'Zoom Height', then 'Restore Height' after you 
maximize.  But if on a screen small enough that the initial height is the same 
as zoomed, IDLE might get confused.  No change on Linux in the PR is the 
intention, so that is good.

Is getting accurate coverage reports not enough?

[issue37055] Numerous warnings with blake2 module

[Christian Heimes]

Christian Heimes  added the comment:

The file blake2ns.h renames some of the exported constants to prefix them with 
PyBlake2_foo. The file needs to be updated every time the sources are updated.

I'll look into the issue.

[issue37048] ssl module: QUIC support for HTTP/3

[Christian Heimes]

Christian Heimes  added the comment:

Thanks for your feedback!

So far I actively refrained from exposing or implementing any encryption 
primitives and API like AES, ChaCha20, and ECDSA. I'm worried about potential 
legal issues and export control restrictions. I have to talk to VanL first.

On the other hand, if this causes troubles, feel free to just replace u"bar" 
with "bar" in that test. It is not really important.

[issue37054] Ignored exceptions in test_memoryio

[Antoine Pitrou]

New submission from Antoine Pitrou :

I see the following kind of exceptions when running test_memoryio:

Exception ignored in:

  File "/home/antoine/cpython/default/Lib/_pyio.py", line 409, in __del__

ok

It seems this could be related to issue18748.

[issue4356] Add "key" argument to "bisect" module functions

[Rémi Lapeyre]

Rémi Lapeyre  added the comment:

Can you not use functools.cmp_to_key() for this?


Here's an example:

>>> import bisect, functools
>>> l = [('f', 5), ('d', 3), ('c', 2), ('b', 1), ('a', 0)]
>>> def cmp(a, b):
... if a > b: return -1
... if a < b: return 1
... return 0
... 
>>> bisect.bisect(l, ('e', 4), key=functools.cmp_to_key(cmp))
1
>>> l
[('f', 5), ('d', 3), ('c', 2), ('b', 1), ('a', 0)]
>>> bisect.insort(l, ('e', 4), key=functools.cmp_to_key(cmp))
>>> l
[('f', 5), ('e', 4), ('d', 3), ('c', 2), ('b', 1), ('a', 0)]

[issue4356] Add "key" argument to "bisect" module functions

[Neil Girdhar]

Neil Girdhar  added the comment:

The problem with `key=lambda item: -item` is that item cannot always be easily 
negated.  For example, tuples are often used as keys.

[issue37049] Implement PEP 589: add TypedDict to typing

[Chih-Hsuan Yen]

Chih-Hsuan Yen  added the comment:

Regarding the round-trip issue in Lib/test/test_typing.py mentioned by 
SilentGhost:

Apparently the following line added in b891c465bb7d38a597c5c2ad547d7b19194f4dad 
triggers an issue in Tools/parser/unparse.py

Literal[b"foo", u"bar"]

As this is more likely an issue in unparse.py instead of test_typing.py, I 
opened another ticket for tracking: #37053.

[issue37053] Tools/parser/unparse.py does not handle u"bar" correctly

[Chih-Hsuan Yen]

New submission from Chih-Hsuan Yen :

Currently (135c6a56e55d2f4f8718b3b9f03ce3c692b15f0f) the following test fails:

./python -m test.regrtest -v test_tools.test_unparse -u cpu

(Note that -u cpu is needed to force test_unparse.DirectoryTestCase to check 
all files under Lib/ and Lib/test/.)

An example error message:

)

Apparently that's because Tools/parser/unparse.py does not handle strings like 
u"bar" correctly. I managed to "fix" it with the following patch:

diff --git a/Tools/parser/unparse.py b/Tools/parser/unparse.py
index 385902ef4b..a25b5e49df 100644
--- a/Tools/parser/unparse.py

 elif value is ...:
 self.write("...")
 else:

 def _List(self, t):

Not sure if this is the correct approach, though.

[issue37039] IDLE: Improve zoomheight doc and behavior.

[Serhiy Storchaka]

Serhiy Storchaka  added the comment:

I do not have "Zoom/Restore Height". I have only "Restore Height" which 
maximizes the height. The result looks identical with and without PR 13576 
applied. There is no overlapping nor gap between the IDLE windows and the 
bottom panel.

[issue27860] Improvements to ipaddress module

Inada Naoki  added the comment:

Because I treats this is just a code cleanup.

I didn't thought it was a bug.
I don't know it is real bug which should be backported to 3.7 for now.

> Incidentally, there are also no tests for this behavior.

Because I thought there are no change about public (documented) behavior.

> Just to note: both merged PRs lacked news entry.

NEWS entry is not needed for code cleanup.
