>From https://docs.python.org/3/reference/datamodel.html#object.__hash__
User-defined classes have __eq__() and __hash__() methods by default; with
them, all objects compare unequal (except with themselves) and x.__hash__()
returns an appropriate value s

Seems I learned a python lesson today.
I've put myself back in python school and done some reading on a) the code
behind dataclasses, b) PEP 557 and c) the doc'n for __eq__.
After all the reading I've realised this I'd been making some as
New submission from Craig Coleman :
In a test, dataclasses generate an __eq__ function appears to be wrong.
@dataclass
class C:
pass
class K:
pass
a = C()
b = C()
c = K()
d = K()
(a is b) # False
(a == b) # True # Incorrect, Why?
(c is d) # False
(c == d) # False # Correct
New submission from Coleman :
When using shuttle. copy file on the Google Drive File Stream file way, an
incorrect SameFileError can happen.
MWE (assuming foo.txt exists in your google drive G:\\):
>>> f1 = 'G:\\My Drive\\foo.txt'
>>> f2 = 'G:\\My D

Six years later and I'm still running into this exact bug with
``subprocess.CalledProcessError`` on python 2.7.12 when doing a
``multiprocessing.Pool.map`` and trying to catch errors from
``subprocess.check_output``.
What's the reason it was never
Mike Coleman added the comment:
Just to confirm, the real problem here was that tiny packets were being
sent out by default, and the obvious fix (altering ac_out_buffer_size)
didn't work.
Looking at the code, it appears that the change by Josiah Carlson
(#64062) causes ac_out_buffer
Mike Coleman added the comment:
My original report didn't mention it specifically, but I believe I was
hitting the FD_SETSIZE limit that Frank mentioned. (Thanks for working
on this!)

I also ran into this bug.
In my case I'm able to work around this by "reserving" some fds at the
start of my program (open 20 reserved fds, open 2000 real fds, close 20
reserved fds), but this is both a kludge and not a general solution.

Also, as with the other python versions, notice that the error status is

New submission from Mike Coleman :
$ python3.0 -c 'print((1, 2, 3))' > /dev/full || echo error status

This command gives no indication whatsoever that anything has gone
wrong. Following this with strace demonstrates that the interpreter is
in fact ignoring these errors:

Oops, I should have used the old python print syntax. Nonetheless, the

The above sequence should also output 'error status' before the next

I'll go down to the cemetery and see if I can dig one up. :-)
All of our Tru64 machines have been powered-down for over three years
now, so as far as I'm concerned you can mark this one as no longer relevant.
New submission from Mike Coleman :
I was thrown by the "Failed to find the necessary bits to build these
modules" message at the end of newer Python builds, and thought that
this indicated that the Python executable itself was not built.
That's arguably stupidity on my part,

Okay. For what it's worth, note that my original 2004 patch for this

I think it's probably both. The original design was incorrect, though
this probably wasn't apparent to the designer. But as a significant
user of 're', it really stands out as a problem.

The other place I see the constant is in asyncore.py:

Mike Coleman added the comment:
The value is used there, but this is not effective in causing larger
packets to be sent, which I noticed by watching with strace. I think
the reason for this is that 'refill_buffer' will only make at most one
call to simple_producer.more, and that
New submission from Mike Coleman:
In asynchat, 'push' doesn't specify 'buffer_size', so the default of 512
is used. This is bogus and causes poor performance--it should use the
value of 'ac_out_buffer_size' instead.

Well, I think we can conclude that it's expected by *them*. :-) I
still find it surprising, and it somewhat lessens the utility of
re.split for my use cases. (I think re.finditer may also suffer from
the same problem, but I don't recall.)
