[issue42099] Fix reference to ob_type in unionobject.c and ceval

2020-10-20 Thread Neil Schemenauer 


New submission from Neil Schemenauer :

It is great that access to ob_type has been cleaned up to use an access macro.  
There are two spots that still need fixing.

I think we should do something to help avoid this kind of thing slipping into 
the code in the future.  E.g. a special build flag that renames the ob_type 
member would work.  I'll make a separate bug for that.

[issue42098] Test suite should verify auditing events get triggered

2020-10-20 Thread A.M. Kuchling 


New submission from A.M. Kuchling :

During the 3.10 development process, a call to `sys.audit()` got accidentally 
removed from the glob module. No tests caught it.

This is clearly bad. sys.audit() is intended for security-related purposes and 
can result in operations being cancelled, so someone may be relying on a 
particular event being triggered to catch a risky situation. If we then 
accidentally remove the audit event, that's a security hole.

The test suite should be verifying that audit events get triggered when we 
expect.  Presumably we'll need some kind of context manager or assertion that 
will do something like: 

  with self.assertAuditEventTriggered('glob.glob', 'path'):
glob.glob('path')

Before anyone suggests it might be the logstash code we're calling in the 
comment, it ain't. 

The bug is easily replicated using entirely python built in code. See test.py 
attached.

If you're having trouble triggering it (seems to vary per machine), find:
pl.map(do_work, range(1))

And add a few zeros into the range()

[issue41737] Improper NotADirectoryError when opening a file in a fake directory

2020-10-20 Thread Danny Lin 


Danny Lin  added the comment:

> Really? It's not obvious that finding a file would involve directory 
> operations?

Not in some senses, and that's possibly why Windows does not raise 
NotADirectoryError in such case.

I agree that it's a platform-specific implementation detail. However, there are 
lots of platform-specific implementation details written in documentation 
elsewhere already, especially OS related modules such as os and os.path. I 
don't think mentioning platform-specific implementation details for subclasses 
of OSError would be any less reasonable than that.

Adding such notice for NotADirectoryError helps people who want a EAFP style 
code for nonexistent file by preventing them getting trapped writing a 
cross-platform code.

[issue41737] Improper NotADirectoryError when opening a file in a fake directory

2020-10-20 Thread Eryk Sun 


Eryk Sun  added the comment:

Regarding documentation, builtin open() and the io and os modules generally do 
not provide information about platform-specific errors. But documenting the 
behavior for the NotADirectoryError exception itself may be useful considering 
it applies to many POSIX functions that access filepaths, such as stat, open, 
mkdir, rmdir, unlink, and rename.

Regarding behavior, I don't see anything reasonable that can or should be done 
for POSIX. In Windows, it should be possible to know whether FileNotFoundError 
is due to a bad path prefix (ERROR_PATH_NOT_FOUND, 3) or a missing file 
(ERROR_FILE_NOT_FOUND, 2), but io.FileIO currently only uses standard C errno, 
which maps both of these cases to ENOENT. So one behavior that *can* be fixed 
in this situation is to get the actual Windows error code from MSVC _doserrno, 
such that the raised FileNotFoundError would have the relevant Windows error 
code in its winerror attribute.

[issue42104] xml.etree should support contains() function

2020-10-20 Thread karl 


New submission from karl :

In XPath 1.0 
The function contains() is available 

> Function: boolean contains(string, string)
> The contains function returns true if the first argument string contains the 
> second argument string, and otherwise returns false.

In https://www.w3.org/TR/1999/REC-xpath-19991116/#function-contains


```

   One attribute: doc
   Two Attributes: doc test
   One Attribute: test

```

Currently, we can do this

```
>>> from lxml import etree
>>> root = etree.fromstring("""
...One attribute
...Two Attributes: doc test
...Two Attributes: doc2 test
... 
... """)
>>> elts = root.xpath("//p[@class='doc']")
>>> elts, etree.tostring(elts[0])
([], b'One attribute\n   ')
```


One way of extracting the list of 2 elements which contains the attribute doc 
with XPath is:


```
>>> root.xpath("//p[contains(@class, 'doc')]")
[, ]
>>> [etree.tostring(elt) for elt in root.xpath("//p[contains(@class, 'doc')]")]
[b'One attribute: doc\n   ', b'Two 
Attributes: doc test\n   ']
```


There is no easy way to extract all elements containing a "doc" value in a 
multi-values attribute in python 3.10 with xml.etree, which is quite common in 
html. 


```
>>> import xml.etree.ElementTree as ET
>>> root = ET.fromstring("""
...One attribute: doc
...Two Attributes: doc test
...One Attribute: test
... """
... )
>>> root.xpath("//p[contains(@class, 'doc')]")
Traceback (most recent call last):
  File "", line 1, in 
AttributeError: 'xml.etree.ElementTree.Element' object has no attribute 'xpath'
```

[issue42101] Allow inheritance of Venvs

2020-10-20 Thread Matthias Bussonnier 


New submission from Matthias Bussonnier :

Followup from Python Idea: 

https://mail.python.org/archives/list/python-id...@python.org/thread/KTIYUEYF6XBHOGOLV744RQXMTETVSTOF/

Goal would be to allow layering on virtualenv to speedup creation and use less 
disk space in the case of many large venv having the same base. 

This would be based on an private internal patch that would be upstreamed.

[issue42103] DoS (MemError via CPU and RAM exhaustion) when processing malformed Apple Property List files in binary format

2020-10-20 Thread Robert Wessen 


New submission from Robert Wessen :

In versions of Python from 3.4-3.10, the Python core plistlib library supports 
Apple's binary plist format. When given malformed input, the implementation can 
be forced to create an argument to struct.unpack() which consumes all available 
CPU and memory until a MemError is thrown as it builds the 'format' argument to 
unpack().

This can be seen with the following malformed example binary plist input:

```
$ xxd binary_plist_dos.bplist
: 6270 6c69 7374 3030 d101 0255 614c 6973  bplist00...UaLis
0010: 74a5 0304 0506  00df 4251 4351 44a3  t.BQCQD.
0020: 0809 0a10 0110 0210 0308 0b11 1719 1b1d  
0030:  0101    000b    
0040:      0029...)

```
The error is reached in the following lines of plistlib.py:
(https://github.com/python/cpython/blob/e9959c71185d0850c84e3aba0301fbc238f194a9/Lib/plistlib.py#L485)

```
def _read_ints(self, n, size):
data = self._fp.read(size * n)
if size in _BINARY_FORMAT:
return struct.unpack('>' + _BINARY_FORMAT[size] * n, data)
```
When the malicious example above is opened by plistlib, it results in 'n' being 
controlled by the input and it can be forced to be very large. Plistlib 
attempts to build a string which is as long as 'n', consuming excessive 
resources.

Apple's built in utilities for handling plist files detects this same file as 
malformed and will not process it.

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

David Antonini  added the comment:

Somehow I missed the follow up here until now. I don't remember the original 
code, but I'm fairly confident that mocked_print is the patched print function 
eg 
with patch('dionysus_app.class_functions.print') as mocked_print:

Probably solved in this commit dated the same day as the bug report:

don't think we need to backport such a minor docs issue to 3.8. The PR is old

Ken Jin  added the comment:

+1 to this. I'm more surprised that callable wasn't already able to do that 
(also surprised at the ``isinstance(x, callable)`` code crashing). 

I think the implementation would be slightly different than what you proposed. 
I'd like to give it a shot if you aren't already doing this, and if there's 
more support for this too.

[issue42102] Make builtins.callable "generic"

2020-10-20 Thread Shantanu 


New submission from Shantanu :

In the post PEP 585 world, it seems like a bit of a stumbling block for 
builtins.callable to not able to be parametrised (in a runtime context). Post 
PEP 604, I'd expect typing.Callable to be the most used typing import after 
typing.Any, so much of PEP 585's rationale should apply to this case too.

Concretely, one way to implement this would be to turn callable into a type 
whose __new__ returns a bool and which implements __class_getitem__. We could 
throw in an __instancecheck__ so that `isinstance(x, callable) == callable(x)`.


PS: Despite being code that crashes instantly, I was still able to find some 
instances of `isinstance(x, callable)` on popular Github projects: 
https://grep.app/search?q=isinstance%5C%28.%2A%2C%20callable%5C%29=true=true

Hey Victor, should we try to land this in Python 3.10? 

Given that no one has brought up any big concerns aside from LD_PRELOAD based 
hacks and how clang has already had this as the default I think it's relatively 
safe to make a default for with-optimizations.

[issue30680] textwrap should treat Unicode em-dash like ASCII em-dash

2020-10-20 Thread Inada Naoki 


Inada Naoki  added the comment:

> Agreed. It makes great sense that textwrap started as highly ASCII-centric. 
> But in the Python 3, Unicode-friendly era, ASCII-biased isn't where we should 
> leave things.

It needs Unicode experts. If we support Unicode, we should implemente UAX #14.
http://www.unicode.org/reports/tr14/tr14-45.html

But I am not sure some core developer love textwrap and Unicode enough to 
implement it.
It can be implemented in 3rd party package before adding it in stdlib.

Then, is U+2014 really important to implement even though we can not implement 
UAX#14 in foreseeable future?
It doesn't make sense to me.
