[issue42752] multiprocessing Queue leaks a file descriptor associated with the pipe writer (#33081 still a problem)

[mattip]

mattip  added the comment:

Just to be clear, here is the code from the test (how do you format a code 
block here?) that demonstrates the writer is not closed when nothing is put 
into the queue

```
$ python3
Python 3.8.6 | packaged by conda-forge | (default, Oct  7 2020, 19:08:05) 
[GCC 7.5.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import multiprocessing
>>> q = multiprocessing.Queue()
>>> q.close()
>>> q.join_thread()
>>> q._reader.closed
True
>>> q._writer.closed
False
>>> 

```
And the changed behaviour to close the writer if the queue is used

```
>>> q = multiprocessing.Queue()
>>> q.put(1)
>>> q.get()
1
>>> q.close()
>>> q.join_thread()
>>> q._reader.closed
True
>>> q._writer.closed
True

```

[issue42801] Exception catching function crashes on recursive list

New submission from Steven D'Aprano :

This function crashes on the following recursive list:

try:
return sum(length(i) for i in x)
except Exception:
return 1


a = [[1, 2, 3], [4, 5, 6]]
a.append(a)
length(a)


Crashes:


Fatal Python error: _Py_CheckRecursiveCall: Cannot recover from stack overflow.

For brevity I've cut some of the output. There are about fifty pairs of "line 3

[issue42752] multiprocessing Queue leaks a file descriptor associated with the pipe writer (#33081 still a problem)

[Alex Orange]

Alex Orange  added the comment:

Well, having not heard anything I decided to just make a patch and throw it up. 
Here it is. This includes a test that will fail with the old version and passes 
once patched as well as the patch to the queue code itself.

Worth noting, the CleanExchange class is used because simpler things like using 
a closure to pass the exchange mechanism hold a reference to the Queue one way 
or another that is difficult/impossible to kill. This is because the 
intermediate thread mechanisms hold a reference to all the arguments that are 
passed to the run function. CleanExchange allows an indirect reference to be 
passed and for the reference to Queue to be None'd out.

[issue42799] Please document fnmatch LRU cache size (256) and suggest alternatives

[Raymond Hettinger]

Raymond Hettinger  added the comment:

In addition to documenting the cache size, consider a substantial increase to 
the limit.   Compiled regex patterns tend to be very small.  We can afford to 
have a lot of them (tens of thousands seems reasonable to me).

Regarding the suggested alternative, ISTM that calling translate() directly 
doesn't help much.  For a cache miss, the overhead of the lru_cache() is very 
small relative to the work done by translate().

[issue42800] Traceback objects allow accessing frame objects without triggering audit hooks

[Ammar Askar]

New submission from Ammar Askar :

It is possible to access all the frame objects in the interpret without 
triggering any audit hooks through the use of exceptions. Namely, through the 
traceback's tb_frame property. Ordinarily one would trigger the 
"sys._current_frames" or "sys._getframe" event but this code path bypasses 
those.

There is already precedent for raising events for certain sensitive properties 
such as `__code__` in funcobject. (through a "object.__getattr__" event) so 
perhaps this property should be protected in a similar way.


This issue was recently demonstrated in a security competition:
* https://github.com/hstocks/ctf_writeups/blob/master/2020/hxp/audited/README.md
* https://github.com/fab1ano/hxp-ctf-20/blob/master/audited/README.md

[issue42797] Allow doctest to select tests via -m/--match option

[Steven D'Aprano]

Steven D'Aprano  added the comment:

I think that -m is unacceptable as it will clash with Python's -m option.

I'm not convinced that this added complexity will provide enough benefit to 
make it worth while. I can see myself spending an order of magnitude more time 
trying to work out why my test suffixes and indexes are selecting the wrong 
tests than I would save.

The use of indexes to select individual tests within a single docstring is 
especially fragile and error-prone since it requires counting by the user. It's 
also likely to introduce artificial errors since tests can rely on side-effects 
of previous tests, e.g.

>>> import math
>>> math.sqrt(25)
5.0

Selecting test number 1 alone will fail unless test number 0 is also run. For 
these reasons, I think that in practice, the finest selection unit we can run 
is a single docstring. Trying to select individual tests within a unit is 
likely to be far too fragile and error prone to be practical.

So by my estimation, we have the following selections:

- module docstring alone
- named function or class docstring alone
- named class.method docstring alone
- named class and all its methods

[issue42799] Please document fnmatch LRU cache size (256) and suggest alternatives

[Josh Triplett]

New submission from Josh Triplett :

fnmatch translates shell patterns to regexes, using an LRU cache of 256 
elements. The documentation doesn't mention the cache size, just "They cache 
the compiled regular expressions for speed.". Without this knowledge, it's 
possible to get pathologically bad performance by exceeding the cache size.

Please consider adding documentation of the cache size to the module 
documentation for fnmatch, along with a suggestion to use fnmatch.translate 
directly if you have more patterns than that.

[issue42454] Move slice creation to the compiler for constants

[Mark Dickinson]

Mark Dickinson  added the comment:

@Batuhan Taskaya: would it be worth starting a discussion on either 
python-ideas or python-dev? (Or on discuss.python.org.)

My concern is that we're discussing a core language change. It's not a major 
change, but it's not an insignificant one either, and right now the discussion 
is buried in an issue whose description and "Type" category suggest that it's 
purely about performance - those giving this issue a casual glance may not 
realise that there's a language change involved.

I don't have strong opinions on the change itself either way, but others might 
have.

[issue42797] Allow doctest to select tests via -m/--match option

[Costas Basdekis]

New submission from Costas Basdekis :

Most testing frameworks allow for only a subset of tests to be run, and the 
reason is usually either to focus on a specific test among many failing ones, 
or for speed purposes if running the whole suite is too slow.

With doctests, it's usually the case that the are light and fast, but if you 
make a breaking change you can still have many tests failing, and you want to 
focus only on one.

This proposition adds an `-m`/`--match` option to the doctest runner, to allow 
to select 1 or more specific tests to run.

The proposed format for the parameters is :
* :
*  is a glob-like string where '*' characters can match any 
substring of a test's name, and an '*' is implicitly added to the start of the 
pattern: eg 'do_*_method' matches '__main__.do_a_method' and 
'__main__.MyClass.do_b_method'
*  is a list of numbers or ranges to match the 0-based index examples 
within the test:  eg '1' matches the second example, `-3` matches the first 4 
examples, '4-` matches all but the first 4 examples, and `-3,5,7-10,20-` 
matches examples 0, 1, 2, 3, 5, 7, 8, 9, 10, 20, and the rest

[issue38780] SysLogHandler crash atexit

[Jason R. Coombs]

Jason R. Coombs  added the comment:

I started work on a test in 
https://github.com/jaraco/cpython/tree/bugfix/bpo-38780-test, but (a) the test 
was failing to exhibit the expected failures, and (b) I realized that the fix 
isn't having the intended effect either, because for unix sockets, [self.socket 
is unconditionally 
set](https://github.com/python/cpython/blob/dfdca85dfa64e72df385b3a486f85b773fc0f135/Lib/logging/handlers.py#L872),
 overriding any NullSocket or None value.

The SysLogHandler code will need to be reorganized if self.socket is intended 
to model two modes (broken and initialized).

I'm not sure when I'll get another chance to take a look at this, but I'll not 
be able to wrap it up today, so I'm going to unassign it for now.

[issue42454] Move slice creation to the compiler for constants

[Batuhan Taskaya]

Batuhan Taskaya  added the comment:

I've given this another shot, but even though I was able to create a patch that 
preserved slices as (type(slice), start, stop, step) tuples in the 
consts_cache, this final optimization prevented me to finalize it; 
https://github.com/python/cpython/blob/master/Python/compile.c#L5855-L5858

So, unless anyone else came up with a reasonable idea to do this optimization 
at the compile-time without actually making them hashable, I am re-proposing 
the idea of making them hashable.

Pro:
  - Up to %30+ speedup on slicing with constants (extremely common)
Cons:
  - Mappings accepts slices, which would rarely lead some esoteric cases (like 
the examples given)

Comments would be appreciated

[issue42796] tempfile doesn't seem to play nicely with os.chdir on Windows

[Gabriele Tornetta]

New submission from Gabriele Tornetta :

The following script causes havoc on Windows while it works as expected on  
Linux

~~~ python
import os
import tempfile


def test_chdir():
with tempfile.TemporaryDirectory() as tempdir:
os.chdir(tempdir)
~~~

Running the above on Windows results in RecursionError: maximum recursion depth 
exceeded while calling a Python object (see attachment for the full stacktrace).

PEP 552 was a necessary but not sufficient step on the road towards fully 
deterministic pycs. The PEP says: "(Note there are other problems [1] [2] we do 
not address here that can make pycs non-deterministic.)" where [1] and [2] are 
basically the issues Inada-san has linked.

Hum, maybe there is a misunderstanding on the PEP 552 purpose.

I understood that the main point of the PEP 552 is to compare hash(), rather than checking the .py and .pyc file modification time.

It doesn't magically make the PYC file content fully reproducible. Correct me 
if I misunderstood PEP 552 as well.

[issue42795] Asyncio loop.create_server doesn't bind to any interface if host is a sequence with jus the empty string

[Paolo Lammens]

New submission from Paolo Lammens :

When a sequence containing just the empty string (e.g. `['']`) is passed as the 
`host` parameter of `loop.create_server`, the server seems not to bind to any 
network interface. Since, per the 
[documentation](https://docs.python.org/3/library/asyncio-eventloop.html#asyncio.loop.create_server)
 for `create_server`, the empty string means "bind to all interfaces", 

> If host is an empty string or None all interfaces are assumed and a list of 
> multiple 
> sockets will be returned (most likely one for IPv4 and another one for IPv6).


and also

> The host parameter can also be a sequence (e.g. list) of hosts to bind to.

I would have expected a list containing the empty string to also work as 
expected, i.e. "binding to all hosts in the sequence", so binding to "" and 
thus to every interface.

Example:

Server script:

```python
import asyncio


async def server():
async def connection_callback(reader, writer: asyncio.StreamWriter):
print(f"got connection from {writer.get_extra_info('peername')}")
writer.close()
await writer.wait_closed()

s = await asyncio.start_server(connection_callback, host=[''], port=4567)
async with s:
print("starting server")
await s.serve_forever()


asyncio.run(server())
```

Client script:

```python
import asyncio


async def client():
reader, writer = await asyncio.open_connection("127.0.0.1", 4567)
print(f"connected to {writer.get_extra_info('peername')}")
writer.close()
await writer.wait_closed()


asyncio.run(client())
```

Expected:

- Server:
  ```
  starting server
  got connection from ('127.0.0.1', x)
  ```

- Client:
  ```
  connected to ('127.0.0.1', x)
  ```

Actual:

- Server:
  ```
  starting server
  ```

- Client: a ConnectionError is raised (the host machine refused the connection)

[issue37157] shutil: add reflink=False to file copy functions to control clone/CoW copies (use copy_file_range)

[Albert Zeyer]

Albert Zeyer  added the comment:

I did some further research (with all details here: 
https://stackoverflow.com/a/65518879/133374).

See vfs_copy_file_range in the Linux kernel. This first tries to call 
remap_file_range if possible.

FICLONE calls ioctl_file_clone. ioctl_file_clone calls vfs_clone_file_range. 
vfs_clone_file_range calls remap_file_range. I.e. FICLONE == remap_file_range.

So using copy_file_range (if available) should be the most generic solution, 
which includes copy-on-write support, and server-side copy support.

There is no difference between normal pyc and optimized pyc.

* frozenset is deterministic if PYTHONHASHSEED is set
* FLAG_REF is unstable. It is based on reference count but it is changed by 
various environment (environment variables, build path, order of py files, and 
any other thing using interned strings). bpo-30493 must be fixed.

The my code is folowing

for i in range(1, 5):
a = i + 0.5
b = round(a)
print(a, "rounded as =>", b)

output is

1.5 => 2
2.5 => 2
3.5 => 4
4.5 => 4

the rounding is not correct in output
