[issue21109] tarfile: Traversal attack vulnerability

[shashank]

shashank  added the comment:

Figured a fix for the bug I found, trick was to keep track of current working 
dir of symlink it was trying to evaluate.

Attached patch: safetarfile-3.diff
Patch is for code only.

I'd like to see this go thorough, and would appreciate feedback.

[issue34675] Avoid terminology related to slavery

[Freed_Slave]

New submission from Freed_Slave :

It is very good to see that "master" and "slave" terminology was removed from 
the project, however there are still references to "owned" references, as if 
these references were property. There are also things needing to be "freed" as 
if they were indentured servants.

I would like to open up discussion about better terminology - and when better 
terminology has been agreed upon I do not mind submitting a PR to get rid of 
this exclusive language.

"Freed" terminology:

* https://github.com/python/cpython/search?q=freed&unscoped_q=freed

There are also additional instances were "free" is used instead of "clear" but 
the context makes it harder to discover with a naive search.

"Owned" terminology:

* https://github.com/python/cpython/search?utf8=%E2%9C%93&q=owned&type=

"Master/Slave" terminology, now removed:

* https://bugs.python.org/issue34605

On the topic of inclusive/exclusive terminology, there are other problematic 
things that should be addressed - either here or in separate issues. However 
I'd like to draw attention to one particularly sexist email in 
`test_smtplib.py` "my_...@great.cooker.com" - hilarious! Not. It especially 
sticks out among the more generic and inclusive test emails. I particularly 
like the inclusion of "Páolo " but then in a test email he 
makes a sexual innuendo.

* https://github.com/python/cpython/search?utf8=%E2%9C%93&q=mom&type=

* Said innuendo: "oh là là, know what I mean, know what I mean?\n\n")"

[issue31305] 'pydoc -w import' report "no Python documentation found for 'import'"

New submission from Karthikeyan Singaravelan :

As mentioned in the help this works only for modules and since import is a

[issue32933] mock_open does not support iteration around text files.

[Anthony Flury]

Anthony Flury  added the comment:

I still support backporting to 3.6 and 3.7 : 

Yes it is correct that this fix could change the behavior of existing test 
code, but only if someone has written a test case for a function where : 

 1. The function under test uses dunder_iter iteration
 2. The test case provides a read_data content to mock_open
 3. The test case expects a response from the function which 
implies that the file provided is empty/invalid in all cases - regardless 
of the data provided.

I simply cannot see that someone would implement a test case such as this - if 
your file has data, you would expect that your function under test would 
recognize that the data exists, if that data is valid; and most code will 
differentiate between invalid data and empty data.

So the only time I think this fix would change the behavior of existing code is 
if someone has written an illogical test case, which is currently passing and 
would now fail (since the test function will no2 see the data being provided 
and respond as such).

Specifically the only change in behavior to existing code is to highlight an 
invalid test case and potentially a bug in the code under test. It is for this 
reason I support backporting.

Is it something specific to the environment? I tried the test on Ubuntu 16.04 
on both master and on v3.6.3 with no errors. Maybe if you can execute the 
following code based on which the test is executed then it will be helpful to 
debug this.


import locale

foo, enc = locale.getlocale(locale.LC_CTYPE)
# Search non-ASCII letter
for i in range(128, 256):
try:
c = bytes([i]).decode(enc)
sletter = c.lower()
if sletter == c: continue
bletter = sletter.encode(enc)
if len(bletter) != 1: continue
if bletter.decode(enc) != sletter: continue
bpat = re.escape(bytes([i]))
break
except (UnicodeError, TypeError):
pass
else:
bletter = None
bpat = b'A'
# Bytes patterns

print(bletter)
print(bpat)
print(foo)
print(enc)

[issue34616] implement "Async exec"

[Matthias Bussonnier]

Matthias Bussonnier  added the comment:

> A utility to check whether an AST requires async mode should be fairly 
> straightforward.

Here is one case we forgot in IPython apparently :

In [1]: x = 1
   ...: def f():
   ...: nonlocal x
   ...: x = 1

This is not detected as a syntax error, but considered as asyn, we took an 
approach that prefer false positive (try to run invalid syntax as async) than 
false negative (reject valid async-code). Add this to the test suite for this 
feature.

[issue31177] unittest mock's reset_mock throws an error when an attribute has been deleted

[Karthikeyan Singaravelan]

Karthikeyan Singaravelan  added the comment:

Can confirm this behavior on CPython master as well. It seems that when an 
attribute is deleted then a deleted flag is set for the attribute at 
https://github.com/python/cpython/blob/73820a60cc3c990abb351540ca27bf7689bce8ac/Lib/unittest/mock.py#L737
 . But when reset_mock is called it doesn't check for the deleted flag at 
https://github.com/python/cpython/blob/73820a60cc3c990abb351540ca27bf7689bce8ac/Lib/unittest/mock.py#L543

A simple patch would be to skip the deleted as below but some of the code in 
mock module raise an AttributeError. I don't know the correct behavior here. 
But applying the below patch and running tests with `./python.exe 
Lib/unittest/test/` doesn't cause any test failure.

[issue34676] Guarantie that divmod() and PyNumber_Divmod() return a 2-tuple

[Serhiy Storchaka]

New submission from Serhiy Storchaka :

It is documented that divmod() returns a pair of numbers, but the 
implementation doesn't enforce this. Actually divmod() just returns the result 
of __divmod__() or __rdivmod__() without checking it. PyNumber_Divmod() is 
documented as the C equivalent of divmod(). But since it returns a 2-tuple in 
all implemented cases, the user code can expect that it always return a 
2-tuple. This can lead to hidden bugs similar to issue31577.

I think there are no reasons of returning anything except a 2-tuple from 
divmod(). Forcing this conditions can save third-party code from crashes. The 
following PR make divmod() and PyNumber_Divmod() always returning a 2-tuple.

[issue34597] Python needs to check existence of functions at runtime for targeting older macOS platforms

[Ronald Oussoren]

Ronald Oussoren  added the comment:

Linking with newer SDKs is needed to get access to some newer features and 
APIs. That's less relevant for Python itself, but can be relevant for the 
embedding application.  You can still compile Python itself on an older 
machine, then link it into an application build against a newer SDK. This does 
make the build process harder though.

However, there seem to be some issues when you mix code linked for different 
deployment targets, for example 
.
  This is issue contains a C extension that works correctly when CPython is 
build with a new SDK and crashed hard with the interpreters on Python.org.

This is one reason why I will at some time in the future look into this, but I 
cannot say when that will happen because I have limited time to work on this.

[issue34677] Event scheduler page example

[mediator42]

New submission from mediator42 :

Hi,
I am pretty confident, that the example you put on the Event scheduler page 
(https://docs.python.org/3.7/library/sched.html) is somehow strange. 

If the priority argument behave as described, it should print the "keyword" 
line before the "positional" line, since these events are scheduled for the 
same time but "keyword" has a higher priority than "positional".

When I run this script on my PC it behaves correctly.

[issue34597] Python needs to check existence of functions at runtime for targeting older macOS platforms

[Zorg]

Zorg  added the comment:

> Why do you believe that is safer?  Apple goes to great lengths to provide 
> compatibility for existing applications to keep running on newer systems. 

They also don't want developers to develop using older SDKs. Hypothetically 
speaking, more information may be stored in the binaries, and there could be 
something down the road to opt into that requires all binaries to be linked 
against a certain SDK. Or your code takes an older path based on the SDK 
version at runtime -- python may include some other higher level baggage too, 
like the tkinter stuff for instance.

There is some middle ground other than weak linking; stripping out features 
from the configure part of the project and opt in to using the deprecated APIs. 
Not as ideal as weak linking, but better than building on an older SDK IMO.

[issue32933] mock_open does not support iteration around text files.

[Ned Deily]

Ned Deily  added the comment:

The potential change in behavior affecting existing code was one issue.  But 
the other was the fact that people writing tests to make use of the new 
behavior can't depend on that behavior being there for 3.7 or 3.6 without 
checking the patch level, for example, 3.6.7 vs 3.6.6.  That's one of the main 
reasons we generally do not backport behavior changes unless they are a clear 
bug; as I noted. this particular issue seems somewhere in between a bug and a 
feature.  Given how far along we are in the 3.6.x cycle, I think we definitely 
should not backport to 3.6.  Since 3.7 is near the beginning of its support 
cycle, I would not object if we did backport this for 3.7.1.  I'll leave it up 
to Berker.

[issue34605] Avoid master/slave terminology

[Serhiy Storchaka]

Serhiy Storchaka  added the comment:

News about this issue published on different resources are exaggerated. 
Actually the controversial changes were rejected. All merged changes look 
correct to me, they fix outdated terminology ("worker" instead of "buildslave" 
is now the official term in the Buildbot documentation) and make the 
documentation using more common terminology (for example "parent process" 
instead of "master process" in context of multiprocessing).

[issue34681] Incorrect class name Pattern in sre_parse.py

[Serhiy Storchaka]

New submission from Serhiy Storchaka :

In 8a3ebf8ca87a7d2989148d7c218974ab4235ca5d, with synchronizing regex engine 
with SRE 0.9.6, the class State in sre_parse.py was renamed to Pattern and the 
following comment was added: "master pattern object.  keeps track of global 
attributes".

This name is incorrect and misleading. This class doesn't represents a pattern 
in any sense. It just keeps global flags and groups information for parser. 
There is a class SupParser in sre_parse.py that represents a pattern or its 
part in intermediate representation, and there is a class Pattern defined in 
sre.c and exposed publicly, that represents a compiled pattern.

The proposed PR renames Pattern back to State and renames attribute, parameter 
and variable names for referring to objects of this class from pattern to 
state. All this is an internal API, but since there may be a third-party that 
uses it, it is for developer version only.

[issue26979] The danger of PyType_FromSpec()

[Petr Viktorin]

Petr Viktorin  added the comment:

1) If I understand correctly, this problem could be solved by per-class C 
storage? Something like PyModuleDef.m_size / PyModule_GetState, but for classes?

2) Making PyType_GetSlot work for static types would not be trivial. 
All types do have the same *basic* structure (the tp_* fields), but the 
nb_*/sq_*/etc. fields don't need to be in the same order, and might not exist 
at all.
Even making it work for the tp_* fields only would bake in some assumptions I 
do want to get rid of.
I'd like to understand your use case better. Do you have a specific example 
here?

[issue34676] Guarantie that divmod() and PyNumber_Divmod() return a 2-tuple

[Paul Ganssle]

Paul Ganssle  added the comment:

I would be somewhat worried that this might break something like numpy (though 
not numpy specifically) which might be counting on the ability to write a 
wrapper that overloads this behavior.

Another concern is that people could be playing it fast-and-loose with actual 
types, and are returning something that fits the bill for a 
collections.abc.Sequence with length 2 (e.g. return [a, b]) but isn't an actual 
Tuple.

I would at least think that this should go through a deprecation cycle.

"In either case, it prints a stack backtrace" - most of the time in Python

-0 Perhaps this should be left as-is.  There is no known problem that we would 
be solving and it would add an extra step to a fine-grained function.  In 
general, I think we have these guards in places where it is known that 
downstream callers rely on a particular type signature for the return value.

[issue34683] Caret positioned wrong for SyntaxError reported by ast.c

[Guido van Rossum]

New submission from Guido van Rossum :

Input file with a subtle error: a number where an assignment target is required:

for 1 in []: pass

Run it, it gives a SyntaxError.  Note how the caret pointing to the incorrect 
token is position one to the left of where you'd expect it:

  File "s.py", line 1
for 1 in []: pass
   ^
SyntaxError: can't assign to literal

For every syntax error I've seen that's produced by ast.c this seems to be the 
case -- the caret is always positioned 1 too far left.

I tried to understand how this is happening but my AST-fu is lacking. It seems 
this has been happening since ast.c started added column numbers -- in Python 
2.7 there's no caret at all, but in 3.4 and later there's a caret and it has 
the same problem. (Also in 3.3; I don't have 3.2 or older 3.x lying around to 
test.)

There is a patch and the bug has been put at

Could somebody have a look at it and recommend either at the bug-report or here

[issue34686] Add `-r`, as opposed to `-R` to Python core interpreter

[Erwan Le Pape]

New submission from Erwan Le Pape :

I'm attempting to leverage PEP 552 to make the core interpreter build process 
more deterministic. However, the standard Python Makefile uses `python -E` when 
calling the compileall (and all other setup scripts), which forces 
randomization since it can only be turned off through environment variables 
(which in turn leads to nondeterministic behaviour as noted in PEP 552 [1],[2]).

Also, is adding a flag that disables randomization something that would be 
acceptable? Or are options to the core interpreter to be kept to a minimum and 
this does not represent a large enough use-case?

This would basically hold in Modules/main.c in something as short as:
+ case 'r':
+ config->use_hash_seed = 1;
+ config->hash_seed = 0;
+ break;

Thanks, Ned!

Anthony, I'm one of the maintainers of https://github.com/testing-cabal/mock 
and I'd be happy to merge a PR that backports the fix to the PyPI version of 
mock.

[issue34683] Caret positioned wrong for SyntaxError reported by ast.c

[Benjamin Peterson]

Benjamin Peterson  added the comment:

I think ast.c is in the right here and there are two complementary bugs in 
caret printing and the parser.

print_error_text does this:

while (--offset > 0)
PyFile_WriteString(" ", f);

which is off-by-one if offset is zero-indexed (which it should be IMO).

The parser has an off-by-one error in the other direction. When it reports an 
error, it reports the offset of the tokenizer's "cur" buffer. This is generally 
advanced past the location that actually resulted in a parser error. I believe 
the parser should be fixed to report the error offset as the offset of the 
start of the token that caused the error.

[issue34685] scheduler tests for posix_spawn fail on AMD64 FreeBSD 10.x Shared 3.x

[Pablo Galindo Salgado]

Pablo Galindo Salgado  added the comment:

What is failing is this line in the spawned process:

os.sched_getparam(0).sched_priority != {priority}

For some reason posix_spawn cannot change the priority in BSD. I have tried to 
hardcode the change in the implementation but the priority does not change in 
the child.

I am out of ideas, except skipping the tests on these systems.

[issue24937] Multiple problems in getters & setters in capsulethunk.h

[Petr Viktorin]

Petr Viktorin  added the comment:

Well, hasn't this languished for a while.

I've talked with Benjamin, and he's OK with just removing the "Porting 
Extension Modules to Python 3" HOWTO, and replacing it by links to external 
guides that do a much better job at documenting this.

Also, Python 2.6 and 3.0 is EOL; it should be fine to scrub capsulethunk.
