pip does not find after Python 3.10.4 installed
The Python 3.10.4 (64-bit) and Python Launcher had been (standard) installed successfully. But I could not find pip anywhere. I uninstalled and re-installed a couple of times, it is still the problem. I checked the installed directory C:\Users\x\AppData\Local\Programs\Python\Python310\Tools\Scripts\ and also scanned the whole drive, pip could not be found. I also checked on the web and none of them help. Did I do something wrong? Note: I did install Python 3.8 on another Windows Pro desktop without any problem. Thank very much.

Providing an (invalid) input to the parser causes an exponentially-slow DoS to

[issue46704] Parser API not checking for null-terminator
New submission from anthony shaw :
In tokenizer.c, the translate_newlines() function does a `strlen()` on the
input string, if the string is not null-terminated, e.g.
'\xbe' this leads to a heap-buffer-overflow. The overflow is not exploitable,
but if there are further changes to the parser, it might be worth using a
strlen() alternative, like strnlen().
static char *
translate_newlines(const char *s, int exec_input, struct tok_state *tok) {
int skip_next_lf = 0;
size_t needed_length = strlen(s) + 2, final_length;
This leads to a heap-buffer-overflow detected by ASAN in a simple reproducible
example, calling PyRun_StringFlags() from the LLVM fuzzer:
fuzz_target(47084,0x11356f600) malloc: nano zone abandoned due to inability to
preallocate reserved vm space.

[issue46491] typing: allow Annotated in outermost scope
Anthony Sottile added the comment: 3.7.2 has another example where OrderedDict was added to typing I don't have any personal investment in this particular change but I've had quite a few unhappy consumers of libraries due to instability in typing apis between patch versions in the past (heh and they're especially frustrated because they don't care about type checking and just want functional software) it's also difficult and/or not cost effective to add every patch version to a CI matrix to catch these sorts of problems -- ___ Python tracker <https://bugs.python.org/issue46491> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

currently this works correctly:

Traceback (most recent call last):

my proposal is to implement alignment `__format__` for `None` following the
same as for `str` for alignment specifiers

[issue44467] profiling-compatible functools.wraps
New submission from Anthony Sottile :
this is a small proposal to add a new function to the functools module which
provides better profiling-compatible `@functools.wraps(...)`
the rationale comes from https://github.com/Yelp/named_decorator (which is dead
/ abandoned)
the tl;dr from there is any time a decorator is involved in a profile it
becomes very difficult to trace because everything becomes tangled around
common decorators (because function names are used from the code object)
here is the proposal and an initial implementation:
def wraps_with_name(func, decorator, **kwargs):
def wraps_with_name_decorator(wrapped):
new_name = f'{func.__name__}@{decorator.__name__}'
new_code = wrapped.__code__.replace(co_name=new_name)
# would be nice if `types.FunctionType` had a `.replace(...)` too!
new_wrapped = types.FunctionType(
new_code,
wrapped.__globals__,
new_name,
wrapped.__defaults__,
wrapped.__closure__,
)
return functools.wraps(func, **kwargs)(new_wrapped)
return better_wraps_decorator
the usage would be similar to `functools.wraps`, here is an example:
```python
def my_decorator(func):
@functools.wraps_with_name(func, my_decorator)
def my_decorator_inner(*args, **kwargs):
return func(*args, **kwargs)
return my_decorator
```

[issue44246] 3.10 beta 1: breaking change in importlib.metadata entry points
Anthony Sottile added the comment: here's the performance regressions, they affect any callers of `distributions()` and are even worse on callers of the new apis. a call to distributions() is about 3x slower than in 3.9 here is the setup I am using: virtualenv venv39 -ppython3.9 venv39/bin/pip install flake8 pytest twine pre-commit virtualenv venv310 -ppython3.10 venv310/bin/pip install flake8 pytest twine pre-commit to test just the `distributions()` call I'm using the following: ```console $ venv39/bin/python -m timeit -n 20 -r 20 -s 'from importlib.metadata import entry_points' 'entry_points()' 20 loops, best of 20: 12.5 msec per loop $ venv310/bin/python -m timeit -n 20 -r 20 -s 'from importlib.metadata import entry_points' 'entry_points()' 20 loops, best of 20: 36.7 msec per loop ``` this is a less-extreme example, many applications have more dependencies installed -- but even in this case this is adding ~24ms startup to any application using `entry_points()` -- and it gets worse the return value of `entry_points()` alone isn't all that useful, next an application needs to retrieve its entry points. let's start for the somewhat normal case of retrieving a single category of entry points: ```console $ venv39/bin/python -m timeit -n 20 -r 20 -s 'from importlib.metadata import entry_points' 'entry_points()["flake8.extension"]' 20 loops, best of 20: 12.7 msec per loop $ venv310/bin/python -m timeit -n 20 -r 20 -s 'from importlib.metadata import entry_points' 'entry_points(name="flake8.extension")' 20 loops, best of 20: 37.1 msec per loop $ venv310/bin/python -m timeit -n 20 -r 20 -s 'from importlib.metadata import entry_points' 'entry_points().select(group="flake8.extension")' 20 loops, best of 20: 37.1 msec per loop ``` again, 3x slower and very real time to the end user (~24-25ms) now let's show an example usage that something like flake8 uses where multiple groups are requested (this is common for apps and plugin systems which provide multiple distinct functionalities) ```console $ venv39/bin/python -m timeit -n 20 -r 20 -s 'from importlib.metadata import entry_points' 'eps = entry_points(); eps["flake8.extension"]; eps["flake8.report"]' 20 loops, best of 20: 12.6 msec per loop $ venv310/bin/python -m timeit -n 20 -r 20 -s 'from importlib.metadata import entry_points' 'eps = entry_points(); eps.select(group="flake8.extension"); eps.select(group="flake8.report")' 20 loops, best of 20: 38.2 msec per loop ``` also slower, but an additional ms per call to `.select(...)` and it only gets worse with more and more packages installed here's the versions I'm using to ensure they are up to date: ```console $ venv39/bin/python --version --version Python 3.9.5 (default, May 19 2021, 11:32:47) [GCC 9.3.0] $ venv310/bin/python --version --version Python 3.10.0b2 (default, Jun 2 2021, 00:22:18) [GCC 9.3.0] ``` -- resolution: fixed -> status: closed -> open ___ Python tracker <https://bugs.python.org/issue44246> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue44307] date.today() is 2x slower than datetime.now().date()
New submission from Anthony Sottile :
```console
$ python3.10 -m timeit -s 'from datetime import datetime'
'datetime.now().date()'
50 loops, best of 5: 708 nsec per loop
$ python3.10 -m timeit -s 'from datetime import date' 'date.today()'
20 loops, best of 5: 1.4 usec per loop
```
this surprised me so I dug into it -- it appears a fast path can be added to
`date.today()` to make it faster than `datetime.date.now()` -- though I'm
rather unfamiliar with the functions involved here
here is my ~sloppy patch attempting to add a fast path, I would need some
guidance to improve it and get it accepted:

Anthony Sottile added the comment:
the `.select(...)` api is at least twice as slow as indexing as well:
setup:
```
virtualenv venv39 -p python3.9
venv39/bin/pip install flake8 pytest pytest-randomly
virtualenv venv39 -p python3.10
venv310/bin/pip install flake8 pytest pytest-randomly
```
```python
import importlib.metadata
import sys
import time
def f():
eps = importlib.metadata.entry_points()
if sys.version_info >= (3, 10):
eps.select(name='console_scripts')
else:
eps['console_scripts']
t0 = time.time()
for _ in range(100):
f()
t1 = time.time()
print(f'{t1-t0}')
```
```
$ ./venv39/bin/python t.py
0.687570333480835
$ ./venv310/bin/python t.py
1.3486714363098145
```
it is *way* worse when involving multiple entry points:
```python
import importlib.metadata
import sys
import time
# moved outside of the loop, already showed this component is slower
eps = importlib.metadata.entry_points()
def f():
# common for plugin systems to look up multiple entry points
for ep in ('console_scripts', 'flake8.extension', 'pytest11'):
if sys.version_info >= (3, 10):
eps.select(name=ep)
else:
eps[ep]
t0 = time.time()
for _ in range(1):
f()
t1 = time.time()
print(f'{t1-t0}')
```

[issue44246] 3.10 beta 1: breaking change in importlib.metadata entry points
Anthony Sottile added the comment: > Which types are sneaky and look like built-in types but do not act like them? well for starters, there's the tuple subclass which pretends to be a dict. but it violates substitutability for both `tuple` and `Mapping` so it's not useful in either contexts. mypy complains about incorrect types in overrides for both. the worst part of this is that the `__getitem__` moves from O(1) to O(N) (in some private code this makes importlib.metadata on 3.10 _10x slower than on 3.9_). next there's the `EntryPoints` tuple subclass which looks like a tuple but doesn't at all act like one (__getitem__ fails substitutability for example) -- this is an api break with 3.9 which returned a `list` (can't `.sort()` `.extend(...)`, etc. any more) > Given that backports are available I don't think this is appropriate. re-introducing a backport brings in a tree of dependencies that have been shaky at best with backward compatibility. in other words, using standard library importlib.metadata provides significantly improved compatibility and stability over the moving target backport (and its tree of dependencies, zipp being the one that breaks the most often from experience). you'll notice I closed the flake8 PRs specifically because I didn't want to reintroduce the backport. This backport also globally monkeypatches the import machinery breaking any other consumer as well -- in a tool as popular as flake8 I can't really make that global mutation decision for all of the other consumers. > The typing issues these were *trivially solved* by a dictionary comprehension using `entrypoint.name` -- it really did not need a full rework and break of the api to solve (could have just deprecated the `__iter__` which I actually suggested on the *original implementation* way back in 3.8) > The new APIs are not only easier to describe with types the types describing the new apis require *significant* `# type: ignore`s to pass mypy because they violate basic substitutability. they also cannot be used in any of the contexts they were appropriate for in <3.10 (Dict[str, List[EntryPoint]] or List[Entrypoint] depending on the api). > I'm not aware of a single breakage. I'm sorry but you have to have realized from the many issues on importlib-metadata or the many issues linking to your deprecation issue that there is significant toil caused directly by your change. cpython is meant to be a stable substrate to build upon, please do not force the community to shoulder the burden of your poor api decisions. > even without requiring an updated importlib_metadata backport. your proposed change introduced a different, unrelated package. not without its own maintenance problems (an additional dependency that has to ~work indefinitely, a hack at best to support this breaking change) > Given the amount of adoption already, reverting these changes is likely to > cause more disruption than moving forward with them. I disagree, bigger things have been reverted (see: __future__.annotations) > So far, the only example presented above appears contrived and not an actual > concern I promise you this is not a contrived case, if you look at your issue tracker it has been reported before and by others. For every issue reported there's likely tens or hundreds of others which are not reported. > It's common for Python minor releases to introduce undocumented changes that > are technically incompatible I've seen this as a rationalization for intentional surprise breaking changes but I don't buy it. Additionally your comments about (paraphrased) "the testsuite didn't demonstrate this usecase so I'm free to change it" are frankly a cop out -- your api returned a dict and a list, that's part of the public api -- changing that is a breaking change. -- ___ Python tracker <https://bugs.python.org/issue44246> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Anthony Sottile added the comment: personally I think they should be reverted -- they were not committed in spirit with the backwards compatibility policy: https://www.python.org/dev/peps/pep-0387/#making-incompatible-changes - I don't think they were discussed thoroughly, and when opposition was presented it was not listened to thoroughly: https://github.com/python/importlib_metadata/pull/278 - the change significantly complicates importlib.metadata with lots of sneaky types (they all look like builtin types but do not act like them) - it simultaneously introduces new apis and old apis which will both be around for extended periods of time but immediately moves to DeprecationWarning - the new apis aren't remarkably better than the old apis -- the motivation was written as "typing issues" but without citing actual issues. in fact, the new items are significantly more complicated to type properly - the change breaks many significantly important projects, from perusing related issues it's at the very least flake8, pandas, virtualenv, astropy, pytest, hypothesis -- and hundreds more from a quick github code search -- ___ Python tracker <https://bugs.python.org/issue44246> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue43994] change representation of match as / capture as `Name(..., ctx=Store())`
Anthony Sottile added the comment: at least for static analysis of other python constructs it's very convenient to know from a `Name` node alone whether it's being used in a read or write context -- without this information an ast traversal needs to maintain more information about whether it's a read or write context for pyflakes this is especially important as it needs to know what names are defined in scope (and referenced in scope) to produce diagnostic messages for other tools like `dead` / `vulture` it's useful to identify introduced and referenced names similarly the `as` in `with` does and the target for assignment expressions so I would expect the similar constructs in `match` to do so as well `Name` nodes are also useful for better diagnostic messages as they contain positioning information, which isn't easily extracted from `MatchAs`, etc. -- if I recall correctly, the `asname` for imports was recently extended to add this information for the same purpose -- ___ Python tracker <https://bugs.python.org/issue43994> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue43994] change representation of match as / capture as `Name(..., ctx=Store())`
New submission from Anthony Sottile : I'm looking at adding support to `match` for pyflakes, and the first impression I have is that `MatchAs` is unnecessarily different from `Name` with `ctx=Store()` if it were represented as the latter pyflakes would not require special handling of `match`, it would work the same as the current code I suspect other static analysis tools would benefit from a change as well -- messages: 392531 nosy: Anthony Sottile priority: normal severity: normal status: open title: change representation of match as / capture as `Name(..., ctx=Store())` versions: Python 3.10 ___ Python tracker <https://bugs.python.org/issue43994> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue43933] Regression in python3.10 with traceback frame having lineno of -1
New submission from Anthony Sottile :
This is breaking pytest for failed assertions:
https://github.com/pytest-dev/pytest/pull/8227
It also breaks the traceback in the output below
Here's a minimal example:
```python
class Boom:
def __enter__(self):
return self
def __exit__(self, *_):
raise AssertionError('boom!')
def main() -> int:
with Boom():
raise AssertionError('hi')
if __name__ == '__main__':
exit(main())
```
On python3.9 you get this:
```
Traceback (most recent call last):
File "/home/asottile/workspace/cpython/t.py", line 10, in main
raise AssertionError('hi')
AssertionError: hi
During handling of the above exception, another exception occurred:
Traceback (most recent call last):
File "/home/asottile/workspace/cpython/t.py", line 14, in
exit(main())
File "/home/asottile/workspace/cpython/t.py", line 10, in main
raise AssertionError('hi')
File "/home/asottile/workspace/cpython/t.py", line 5, in __exit__
raise AssertionError('boom!')
AssertionError: boom!
```
output in python3.10:
```
Traceback (most recent call last):
File "/home/asottile/workspace/cpython/t.py", line 10, in main
raise AssertionError('hi')
AssertionError: hi
During handling of the above exception, another exception occurred:
Traceback (most recent call last):
File "/home/asottile/workspace/cpython/t.py", line 14, in
exit(main())
File "/home/asottile/workspace/cpython/t.py", line -1, in main
File "/home/asottile/workspace/cpython/t.py", line 5, in __exit__
raise AssertionError('boom!')
AssertionError: boom!
```
Notice the second to last frame is now missing and invalid (line -1)
I bisected this and found this is the culprit:
https://github.com/python/cpython/commit/3bd6035b6baf1a7d51b7cc2c6bb2c81886236b67
https://github.com/python/cpython/pull/24202
```
3bd6035b6baf1a7d51b7cc2c6bb2c81886236b67 is the first bad commit

bpo-42908: Mark cleanup code at end of try-except and with artificial
(#24202)
* Mark bytecodes at end of try-except as artificial.
* Make sure that the CFG is consistent throughout optimiization.
* Extend line-number propagation logic so that implicit returns after
'try-except' or 'with' have the correct line numbers.
* Update importlib

[issue43737] Documentation of modulo operator should document behaviour clearly when second operator is negative
Anthony Flury added the comment: I fundamentally disagree with closing this - I know that this and many other 'quirks' catch beginners out, and the tutorial is what they use to learn.They don't look in the reference document - it is too dense in BNF definitions which turns a lot of people off from any other useful information - When I was researching this issue I didn't even think to look in the reference section. Looking in the library section for information about the built-in types is also non-obvious to beginners. If the tutorial doesn't contain the detail, and doesn't link to the detail then beginners are left entirely puzzled by the behavior. Given how difficult it is to search the documentation if you don't know exactly what you are looking for, then how beginners would know to look at the FAQ is beyond me. Having communicated with a number of beginners on a number of issues they had no idea that the FAQ even existed. The change didn't 'bury the tutorial in detail' - it added once sentence which linked to the FAQ. In fact all the change did was expand the FAQ entry by a few lines and link to the FAQ from the three places that are relevant. I think this is a small change and it should be the start of making the tutorial beginner friendly. -- resolution: not a bug -> status: closed -> open ___ Python tracker <https://bugs.python.org/issue43737> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
