[issue41026] mailbox does not support new Path object

[Ethan Furman]

Ethan Furman  added the comment:

The problem with using `str()` on a path argument is that the argument may not 
be a str, nor a pathlib object, but `str()` will still create a string out of 
it, leading to difficult bugs.

The documentation for pathlib also predates the addition of `os.fspath()`.

[issue45134] Protocol dealloc not called if Server is closed

[Mark]

New submission from Mark :

If I create_server

server_coro = loop.create_server( lambda: self._protocol_factory(self), 
sock=sock, ssl=ssl)
server = loop.run_until_complete(server_coro)

Then connect and disconnect a client the protocol connection lost and dealloc 
are called.

If however I close the server with existing connections then protocol dealloc 
is never called and I leak memory due to a malloc in my protocol.c init.

  server.close()
  loop.run_until_complete(server.wait_closed())

[issue45116] Performance regression 3.10b1 and later on Windows

[Steve Dower]

Steve Dower  added the comment:

> I'm not sure if PGO builds are reproducible, since there is a training step 
> which requires to run a non-deterministic workload (the Python test suite 
> which is somehow randomized by I/O timings and other stuffs).

I'm 99% sure it's a tracing PGO rather than sampling, so provided everything 
runs in the same order and follows the same codepaths, wall-clock timings 
shouldn't have a significant effect.

Without looking at the generated code, it may be more effective to try and 
force the functions called from the macro to never be inlined. The optimiser 
may be missing that the calls are uncommon, and trying to inline them first, 
then deciding that the whole merged function is too big to inline in places 
where it would be useful.

There's also no particular reason we need to use these tests as the profile, 
it's just that nobody has taken the time to come up with anything better. I'd 
rather see us invest time in generating a good profile rather than trying to 
hand-optimise inlining. (Though the test suite is good in many ways, because it 
makes sure all the extension modules are covered. We definitely want as close 
to full code coverage as we can get, at least for happy paths, but may need 
more eval loop in the profile if that's what needs help.)

[issue45130] shlex.join() does not accept pathlib.Path objects

[Eric V. Smith]

Eric V. Smith  added the comment:

I was using str.join() as an analogy. I apologize if that was confusing.

I'll state this as clearly as I can: I don't think shlex.join() should 
automatically convert any arguments to str, not even those that are Path's.

Nothing is going to be solved by having a discussion on the bug tracker. A 
discussion on python-ideas would be the appropriate place to take this. If a 
consensus is reached there to add this feature, then this feature request can 
be used for its implementation.

It's entirely possible people there might agree with the feature request, but 
I'd argue against it. One thing going for your proposal is subprocess.run(). I 
was thinking issue 38670 applied there, but I guess not.

[issue45130] shlex.join() does not accept pathlib.Path objects

[Richard]

Richard  added the comment:

IMO comparing shlex.join() to str.join() is a mistake. Comparing it to 
subprocess.run() is more appropriate.

What do you mean by "proposal"? subprocess.run() already converts Path 
arguments to str since Python 3.6 (though IIRC this was broken on Windows until 
3.7 or so). It indeed does not convert int arguments, but like I said that's 
irrelevant here, you're the one who brought it up.

[issue45130] shlex.join() does not accept pathlib.Path objects

[Eric V. Smith]

Eric V. Smith  added the comment:

My point is that shlex.join() shouldn’t convert any arguments to strings, no 
matter their type. Just like str.join() doesn’t, and for the same reason. 

Within the last few years there was a discussion on making str.join() 
auto-convert it’s arguments to str, and we decided not to, because it would 
mask too many bugs. I believe the same argument applies to shlex.join(). Path 
objects aren’t special enough to make an exception. 

There’s a proposal somewhere to also call str() on Path arguments to 
subprocess.run(). I’m opposed to that for the same reasons.

[issue45133] Open functions in dbm submodule should support path-like objects

[David Mertz]

New submission from David Mertz :

Evan Greenup via Python-ideas

Currently, in Python 3.9, `dbm.open()`, `dbm.gnu.open()` and `dbm.ndbm.open()` 
doesn't support path-like object, class defined in `pathlib`.

It would be nice to add support with it.

[issue45128] test_multiprocessing fails sporadically on the release artifacts

[STINNER Victor]

STINNER Victor  added the comment:

I'm not sure if unittest.mock code to import the module is reliable: see 
bpo-39551. It imports "multiprocessing", use getattr() to get 
multiprocessing.shared_memory. If getattr() fails with AttributeError, it tries 
to import "mulitprocessing.shared_memory", and then tries again the same 
getattr() on the previously imported "multiprocessing" module.

I'm curious if this change works around the issue:

[issue45130] shlex.join() does not accept pathlib.Path objects

[Richard]

Richard  added the comment:

While it may be primarily intended to combine output from shlex.split() again, 
IMO it's useful for manually constructed command lines as well, for example 
displaying instructions to a user where a path may contain spaces and special 
characters and needs to be properly escaped.

As for converting int to str, since subprocess.run() does not do that, 
shlex.split() does not need to do so either. I never mentioned that, and while 
I could see that being useful as well, that would have to be a separate 
discussion.

There's more of a case for automatic conversion for Path objects, which are 
supposed to work seamlessly in most places where strings are accepted. But such 
quirks of certain functions not accepting them and being forced to convert to 
str manually makes pathlib a little annoying to use compared to os.path.

[issue45130] shlex.join() does not accept pathlib.Path objects

[Eric V. Smith]

Eric V. Smith  added the comment:

I disagree. In my mind, there's no more reason for shlex.join() to take Path 
objects than there is for str.join() to take them, or for shlex.join() to 
convert int's to str's. I'd rather shlex.join() continue to raise an exception 
if passed something that's not a str or bytes.

You should probably discuss this on the python-ideas mailing list if you want a 
broader audience.

[issue32955] IDLE crashes when trying to save a file

[Terry J. Reedy]

Terry J. Reedy  added the comment:

Thank you Irit.

For any users who stumble on this issue:  Drop down clicks in the dialog are 
handled by tk.  Hence, this was not an IDLE issue, unlikely to be a tkinter 
issue, and most likely a bad tcl/tk version issue.  Hence my first post. My 
response and the web are out of date.  We have fixed the version issue by 
including in each installer what seems to be the best available tcl/tk build.

```

(Took me a little while to figure out I had some garbage in a `setup.cfg` file 
in $CWD that was causing it.)

Implications:

Potential implications are that a specially crafted `setup.cfg` might cause a 
security-compromised virtual environment to be created maybe? I don't know.

[issue45116] Performance regression 3.10b1 and later on Windows

[neonene]

neonene  added the comment:

@vstinner: __forceinline suggestion

Since PR25244 (mentioned above), it seems link.exe has got to get stuck on 
python310.dll.
Before the PR, it took 10x~ longer to link than without __forceinline function.
I can confirm with _Py_DECREF() and _Py_XDECREF() and one training-job (the 
more fucntions forced/jobs used, the slower to link).
Have you tried __forceinline on PGO ?


> I don't understand how to read the table.

Overhead field is the output of pyperf command, not subtraction (the answers 
are the same just luckily).

ex) 3.10rc1x86 PGO: 
 PGO  : pyperf compare_to 3.10a7 left
 patched  : pyperf compare_to 3.10a7 right
 overhead : pyperf compare_to right  left 
  are
 1.15x slower (slower 52, faster  4, not significant  2)
 1.13x slower (slower 50, faster  4, not significant  4)
 1.02x slower (slower 29, faster 14, not significant 15)


> I'm not sure if PGO builds are reproducible,

MSVC does not produce the same code. Inlining (all or nothing) might be a quite 
special case in the hottest section.
I suspect the profiler doesn't work well only for _PyEval_EvalFrameDefault(), 
including branch/align optimization.
So my posted macro or inlining is just for a mesureing, not the solution.

Ideally, please provide instructions how to reproduce the bug.  It is hard to

[issue27277] Test runner should try to increase stack size if it is too low

[STINNER Victor]

STINNER Victor  added the comment:

I just pushed a change to reduce the stack memory usage when deleting a chain 
of exceptions in bpo-44348. I consider that this issue is a duplicate. If it's 
not the case, please reopen the issue.

commit fb305092a5d7894b41f122c1a1117b3abf4c567e (upstream/main, main)
Author: Victor Stinner 
Date:   Tue Sep 7 15:42:11 2021 +0200

bpo-44348: BaseException deallocator uses trashcan (GH-28190)

The deallocator function of the BaseException type now uses the
trashcan mecanism to prevent stack overflow. For example, when a
RecursionError instance is raised, it can be linked to another
RecursionError through the __context__ attribute or the __traceback__
attribute, and then a chain of exceptions is created. When the chain
is destroyed, nested deallocator function calls can crash with a
stack overflow if the chain is too long compared to the available
stack memory.

There was work on recursion in newer versions and several similar issues have 
been confirmed to be fixed. Since you didn't include a complete reproduction

[issue45130] shlex.join() does not accept pathlib.Path objects

[Richard]

New submission from Richard :

When one of the items in the iterable passed to shlex.join() is a pathlib.Path 
object, it throws an exception saying it must be str or bytes. I believe it 
should accept Path objects just like other parts of the standard library such 
as subprocess.run() already do.

The code was changed and now instead of calling self.error() it raises an

[issue44869] MacOS Monterrey malloc issue

[Ned Deily]

Ned Deily  added the comment:

The crash report you provide shows a crash in libstdc++ which is normally not 
called directly by the Python interpreter or standard library modules on macOS 
but appears to be being called by libopenblas as provided by the copy of numpy 
in use. Suggest you follow up with the numpy, openblas, or homebrew projects, 
if that's where you obtained numpy and friends. Keep in mind that the problem 
might still be related to the pre-release status of macOS Monterey.  Good luck!

[issue39570] Python 3.7.3 Crash on msilib actions

[Irit Katriel]

Irit Katriel  added the comment:

I personally don't feel like downloading a binary from b.p.o and opening it on 
my machine.

Can you provide more information about the issue? For instance, what do you 
mean by crash? Do you have any stack trace or other output?

What is the value in the registry table that it is trying to read and failing?

[issue45128] test_multiprocessing fails sporadically on the release artifacts

I cannot reproduce it from installed Python or when testing directly on the 
repo, but the error seems to still happen from time to time.
