[issue38837] struct.pack: Unable to pack more than 256 bytes at a time

[Mark Dickinson]

Mark Dickinson  added the comment:

The error you're getting is because you're trying to pack a *value* that's 
larger than 255, not because you're trying to pack more than 256 bytes. Packing 
more than 256 bytes at a time works fine for me.

>>> packed = struct.pack("<512B", *[n//2 for n in range(512)])  # fine
>>> packed = struct.pack("2B", *[255, 256])
Traceback (most recent call last):
  File "", line 1, in 
struct.error: ubyte format requires 0 <= number <= 255

[issue38843] Document argparse behaviour when custom namespace object already has the field set

[Ivan Kurnosov]

Ivan Kurnosov  added the comment:

> I have not seen many questions about the use of a preexisting namespace 
> object (here or on StackOverflow)

as typing was added to the language natively - it should become more and more 
frequently used.

I personally see no reason anymore to NOT use a custom namespace: typed 
arguments object is x100 times better than untyped one.

[issue38843] Document argparse behaviour when custom namespace object already has the field set

[paul j3]

paul j3  added the comment:

It doesn't have to be a special class. It can be a `argparse.Namespace` object. 
 If the preexisting namespace has an attribute set, the action default will not 
over write it.

In [85]: parser = argparse.ArgumentParser() 
...: parser.add_argument('--foo', default='bar') 
...: parser.parse_args([],
 namespace=argparse.Namespace(foo=123, baz=132))   
Out[85]: Namespace(baz=132, foo=123)

This is described in comments at the start of parse_known_args()


# add any action defaults that aren't present
for action in self._actions:
if action.dest is not SUPPRESS:
if not hasattr(namespace, action.dest):
if action.default is not SUPPRESS:
setattr(namespace, action.dest, action.default)

# add any parser defaults that aren't present
for dest in self._defaults:
if not hasattr(namespace, dest):
setattr(namespace, dest, self._defaults[dest])

There are many details about 'defaults' that are not documented.  This might 
not be the most significant omission.  

I have not seen many questions about the use of a preexisting namespace object 
(here or on StackOverflow).  While such a namespace can be used to set custom 
defaults (as shown here), I think it is more useful when using a custom 
Namespace class, one the defines special behavior.

Originally the main parser's namespace was passed to subparsers.  But a change 
in 2014, gave the subparser a fresh namespace, and then copied values from it 
back to the main namespace.  While that gave more power to the subparser's 
defaults, users lost some ability to use their own namespace class.

https://bugs.python.org/issue27859 - argparse - subparsers does not retain 
namespace

https://bugs.python.org/issue9351 - argparse set_defaults on subcommands should 
override top level set_defaults

https://bugs.python.org/issue34827 - Make argparse.NameSpace iterable (closed)

[issue38789] difflib lacks a way to check if results are empty

[Tim Peters]

Tim Peters  added the comment:

I'm taking Raymond's advice to close this for now.  The issue tracker isn't the 
right place to work out ideas - python-ideas is far better for that 
(StackOverflow isn't a good place for that either - StackOverflow is best for 
when you have a very specific use case and get stuck).

While the issues with generators are common to all generators, in the context 
of difflib something else Raymond said should be taken to heart:  using any 
difflib facility is an extremely expensive way to find out that two things are 
equal.  That's a value of use cases!  That is, if you had asked about this on 
StackOverflow and asked for help instead of proposing "a (vague) solution", 
they would have told you at once to check whether `a == b` before dragging 
difflib into it.

Indeed, that's probably why what you're asking about never came up before.  
People generally use difflib only when they know in advance (via a cheap 
equality test) that there _are_ differences to be found.

In any case, if a "specific & actionable" suggestion comes out of pursuing 
this, feel encouraged to open this report again!

[issue38843] Document argparse behaviour when custom namespace object already has the field set

[Ivan Kurnosov]

New submission from Ivan Kurnosov :

At this moment it's impossible to explain the behaviour of this script using 
documentation.

Given it was explicitly coded to behave like that - it should be somehow noted 
in the documentation, that as long as a `CliArgs.foo` field has a default value 
set already - it won't be overwritten with a default argparse argument value.


```
import argparse

class CliArgs(object):
foo: str = 'not touched'


parser = argparse.ArgumentParser()
parser.add_argument('--foo', default='bar')

args = CliArgs()
parser.parse_args(namespace=args)
print(args.foo) # 'not touched'

print(parser.parse_args()) # 'bar'
```

Whilst developing a new unused function check for flake8 ( 
https://github.com/PyCQA/pyflakes/pull/485 ) I ran it against the CPython

[issue38822] Inconsistent os.stat behavior for directory with Access Denied

[Eryk Sun]

Eryk Sun  added the comment:

In attributes_from_dir() in Modules/posixmodule.c, a trailing backslash or 
slash should be stripped from the lpFileName parameter of FindFirstFileW. 
Otherwise the call opens the directory via NtOpenFile, instead of opening its 
parent directory. Even if opening the directory is successful, which we don't 
expect in this case, FindFirstFileW forcibly fails the call with 
ERROR_FILE_NOT_FOUND (2) because it expects a filename filter (e.g. "*") for 
the internal NtQueryDirectoryFile[Ex] system call.

Care needs to be taken to not strip the trailing slash of the root directory of 
a DOS drive because that creates a drive-relative path (e.g. "C:"). It is 
expected that FindFirstFileW will fail for the root of a DOS drive or UNC 
share, since there's no parent directory to open.



"System Volume Information" explicitly grants access only to the SYSTEM 
account. Implicitly we have read-attributes access to this directory because we 
have read-data (i.e. list-directory) access to the root directory. Great, but 
even for 0 desired access, CreateFileW requests both read-attributes and 
synchronize access, even for overlapped I/O (i.e. kernel File objects created 
by CreateFileW can always be waited on). So even an elevated administrator 
normally can't open this directory to query information. However, backup and 
restore privileges are in effect when an open requests backup semantics, which 
we already do. We could extend os.stat to temporarily enable SeBackupPrivilege 
if the caller has it. 

It's also possible to open the directory with a native NtOpenFile or 
NtCreateFile system call, without the FILE_SYNCHRONOUS_IO_NONALERT option and 
without requesting SYNCHRONIZE access -- i.e. the File object will be 
asynchronous and not waitable.

[issue38789] difflib lacks a way to check if results are empty

[Raymond Hettinger]

Raymond Hettinger  added the comment:

Simon, I think the conversation is starting to drift and would best be 
continued on python-ideas or StackOverflow.  Ideas like peekable generators 
have been discussed before but there was almost no uptake.

Several thoughts:

* For equal inputs, ndiff() is supposed to generate non-empty output.  It does 
not just give differences.

* To the extent that you care about empty results from some other iterator, the 
easiest thing to do is follow Tim's advice and just list() the iterator.

* The special case of equal inputs is easily handled before running the diff:

 if a == b:
 do_something_for_the_equal_case(a, b)
 else:
 d = ndiff(a, b)
 do_something_for_the_non_equal_case(a, b, d)

I recommend closing this issue because it hasn't elicted anything that is both 
actionable and desireable.

[issue37228] UDP sockets created by create_datagram_endpoint() allow by default multiple processes to bind the same port

[Nathaniel Smith]

Nathaniel Smith  added the comment:

Ouch, that's nasty. It also has security implications. For example, suppose you 
have a multi-user computer, where one user is has a video call going, which 
transfers packets over UDP. Another user could check what port they're using, 
bind to the same port, and steal half the packets, letting them effectively 
listen in on the first user's phone call.

Well, hopefully most conferencing tools use end-to-end encryption. But the 
point is that we don't normally let unprivileged users steal network traffic 
intended for other users.

[issue37228] UDP sockets created by create_datagram_endpoint() allow by default multiple processes to bind the same port

[Guido van Rossum]

Guido van Rossum  added the comment:

I agree that this is a bad default (and whoever wrote it, probably me, didn't 
know what this does for UDP).  I think the right solution is to change the 
default, not to introduce a new method.

Maybe we can deprecate the default somehow? There currently is a line the 
computes the default based on platform:

if reuse_address is None:
reuse_address = os.name == 'posix' and sys.platform != 'cygwin'


We could change this to issue a deprecation warning stating that in the future 
the default will change to False everywhere. Then in the next release we could 
change the default to False and remove the warning.

[issue38622] _ctypes.dlsym (py_dl_sym) does not trigger audit hooks

[Steve Dower]

Steve Dower  added the comment:

Typically, as soon as I merge, I spot an edge case issue.

PySys_Audit(n, "O", a) is deliberately going to treat 'a' as the tuple of 
arguments (when it is a tuple). This lets us simplify/optimise events where the 
event arguments match the function arguments exactly. If 'a' is not a tuple, it 
gets wrapped in one.

When 'a' is meant to be a single argument that _might_ be a tuple, such as in 
PyObj_FromPtr, the format string needs to be "(O)" to ensure it is treated as a 
one element tuple. This is just how Py_BuildValue works - multiple elements 
become a tuple and the parens are optional unless you want a one-element tuple.

[issue38722] runpy should use io.open_code() instead of open()

[Steve Dower]

Steve Dower  added the comment:

> I hadn't realized that we'd made such a declaration WRT opening of code files 
> in general.

It wasn't exactly a hugely publicised declaration :)

The relevant quote from PEP 578 is:

> All import and execution functionality involving code from a file will be 
> changed to use open_code() unconditionally.

Which I admit is a big claim, and one that was not completely followed through 
with before 3.8.0. Calling it a "security" fix is borderline, as it isn't 
really a vulnerability by default, but calling it incorrect behaviour (i.e. a 
regular bug) is fine by me.

[issue38722] runpy should use io.open_code() instead of open()

[Steve Dower]

Steve Dower  added the comment:

It's a security issue because Python 3.8 says it will open files to be executed 
with io.open_code() instead of open(). This allows a way to bypass that.

That said, this appears to be a fallback case, so I'm not hugely concerned. I 
haven't quite figured out why it would fall back here (that involved reading 
the pkgutil sources ;) ).

I would vote for backporting to 3.8.1, but if Tal wants to push back and nobody 
else has an opinion then whatever.

[issue17013] Allow waiting on a mock

[Ilya Kulakov]

Ilya Kulakov  added the comment:

I have submitted an alternative implementation of this feature heavily inspired 
by _AwaitEvent I wrote for asynctest [0]. 

There was recently an interest from the community towards asynctest to the 
point that got some of its measures merged into CPython [1].

The key features of my implementation [2]:

- Gives meaning to the existing Mock.called property, otherwise not much useful
- Does not require end users to do anything: change is automatically available 
in every Mock (and any subclass of mock that does not override `called`)
- Use of conditionals provides API that allows much richer extension: instead 
of hardcoding conditions as events it allows to wait until arbitrary predicate 
becomes true
- Utilizes existing semantics of python conditionals (both asyncio and 
threading)

Accepting this PR will allow me to bring _AwaitEvent thereby completing mock.py 
with waiting mechanics with identical semantics for both threading-based and 
asyncio-based cases.

[Tal Einat]

Tal Einat  added the comment:

I don't see why this should be considered a security issue.

This should likely have been done when io.open_code() was initially added, but 
now that 3.8 is out, I don't think backporting this would be wise.

[issue38837] struct.pack: Unable to pack more than 256 bytes at a time

[Dave Lotton]

New submission from Dave Lotton :

Using struct.pack it is not possible (Python 3.6.8 and 2.7.15) to pack more 
than 256 bytes at a time.  

This seems like an arbitrarily small number, and seems to be inconsistent with 
the capabilities of the unpack function, which is able to unpack a larger 
number of bytes.

Below demonstrates the issue...

>>> # Create large data set to be packed
>>> data = range(0,512)

>>> # Demonstrate format string for packing
>>> '<%dB' % len(data)
'<512B'

>>> # Try to pack large data set
>>> packed = pack('<%dB' % len(data), *data)
Traceback (most recent call last):
  File "", line 1, in 
struct.error: ubyte format requires 0 <= number <= 255

>>> # Make data set <= 256 bytes
>>> data = range(0,256)
>>> packed = pack('<%dB' % len(data), *data)
>>> # Data successfully packed


>>> # Append another 256 bytes to packed data
>>> packed += pack('<%dB' % len(data), *data)

>>> # Unpack all 512 bytes
>>> unpacked = unpack('<%dB' % len(packed), packed)
>>> 
>>> unpacked

245, 246, 247, 248, 249, 250, 251, 252, 253, 254, 255)




The 256 byte limit on packing seems arbitrarily small and is inconsistent with 
the unpack function.  I'm wondering if there is a rationale for this limit, or 
it has simply been an oversight in the implementation.

I am using Mint Linux 19.2 64-bit (Ubuntu Bionic - based distro).  The problem 
is manifested on both Python 3.6.8 and 2.7.15 included in the distro.

[issue38822] Inconsistent os.stat behavior for directory with Access Denied

[Steve Dower]

Steve Dower  added the comment:

I haven't debugged it, but I'm guessing we're not handling the trailing slash 
properly when falling back to asking the parent directory for information.

Looking at the actual stat result for "C:\System Volume Information" vs. 
"C:\Windows", most of the information is missing in the first case, which 
should mean that we can't access it but we know it's a directory because the 
entry in C:\ said so.

[issue33125] Windows 10 ARM64 platform support

[Steve Dower]

Steve Dower  added the comment:

If the patches are for Tcl/Tk, then you should submit it to them.

I'm not a Tk maintainer, and I never want to be one, so frankly I'd be happier 
to say it's not supported on ARM :)

But if it builds fine with our PCbuild/prepare_tcltk.bat script and people want 
it then I'll keep it.

[issue23407] os.walk always follows Windows junctions

[Steve Dower]

Steve Dower  added the comment:

At a minimum, it needs to be turned into a GitHub PR.

We've made some significant changes in this area in 3.8, so possibly the best 
available code is now in shutil.rmtree (or shutil.copytree) rather than the 
older patch files.

One further step would be to change the VECTORCALL/FASTCALL calling convention 
to pass tstate. But I am not sure what is the risk to do that in Python 3.9? 
Cython uses FASTCALL internally for example.

[issue37228] UDP sockets created by create_datagram_endpoint() allow by default multiple processes to bind the same port

[Yury Selivanov]

Yury Selivanov  added the comment:

I'd be -1 on changing the default of an existing method, at least without 
consulting with a wider audience.  We can add a new method to the loop and 
deprecate create_datagram_endpoint.

I suggest to post to python-dev and discuss this before making any decisions.
