[issue21691] set() returns random output with Python 3.4.1, in non-interactive mode

[Ned Deily]

Ned Deily added the comment:

To expand a bit, this is by design, a consequence of the hash randomization 
feature; see

https://docs.python.org/3/using/cmdline.html#envvar-PYTHONHASHSEED

As noted there, if necessary, it is possible to disable hash randomization.  
But tests with set values or dict keys should not depend on a particular order 
as even disabling hash randomization would not guarantee the same results on 
different platforms or builds of Pythons.

$ python3.4 -c "print(set(['A', 'B']))"
{'B', 'A'}
$ python3.4 -c "print(set(['A', 'B']))"
{'A', 'B'}
$ python3.4 -c "print(set(['A', 'B']))"
{'B', 'A'}
$ PYTHONHASHSEED=0 python3.4 -c "print(set(['A', 'B']))"
{'B', 'A'}
$ PYTHONHASHSEED=0 python3.4 -c "print(set(['A', 'B']))"
{'B', 'A'}
$ PYTHONHASHSEED=0 python3.4 -c "print(set(['A', 'B']))"
{'B', 'A'}

[issue21691] set() returns random output with Python 3.4.1, in non-interactive mode

[Jackson Cooper]

New submission from Jackson Cooper:

The set() built-in returns random output, only when Python 3 is being used, and 
in non-interactive mode (executing a file).

Steps to reproduce:

1. Create file with only print(set(['A', 'B'])) inside it.

2. Execute file with Python 3.4.1 numerous times (10+) over 10+ seconds. The 
output will vary (randomly?) between {'B', 'A'} and {'A', 'B'}.


I can only reproduce this with Python 3.4.1 (have not tried 3.5). It cannot be 
reproduced in Python 2 (2.7.6) interactive or non-interactive mode, or Python 
3.4.1 in interactive mode. Only in Python 3 when executing a file.


Tested on OS X 10.9.3, Python installed via Homebrew.

[issue1559298] test_popen fails on Windows if installed to "Program Files"

[eryksun]

eryksun added the comment:

This is fixed for subprocess.Popen in 2.7, 3.1, and 3.2; see issue 2304. In 
2.7, nt.popen still has this problem. As mentioned above, it can be worked 
around by using subprocess.Popen as described here:

[issue20699] Behavior of ZipFile with file-like object and BufferedWriter.

[Martin Panter]

Martin Panter added the comment:

I have a related issue in Python 3.4. I suspect it is the same underlying 
problem as Henning’s. BufferedWriter is trying to write memoryview() objects, 
but the documentation for RawIOBase.write() implies it only has to accept 
bytes() and bytearray() objects.

>>> from io import BufferedWriter, RawIOBase
>>> class Raw(RawIOBase):
... def writable(self): return True
... def write(self, b): print(b.startswith(b"\n"))
... 
>>> b = BufferedWriter(Raw())
>>> b.write(b"abc")
3
>>> b.close()
Traceback (most recent call last):
  File "", line 1, in 
  File "", line 3, in write
AttributeError: 'memoryview' object has no attribute 'startswith'

[issue21666] Argparse exceptions should include which argument has a problem

[paul j3]

paul j3 added the comment:

In http://bugs.python.org/file30010/nargswarn.patch adding the 
'_expand_help(action)' line should test the help string (during add_argument).

def _check_argument(self, action):
# check action arguments
# focus on the arguments that the parent container does not know about
# check nargs and metavar tuple
try:
self._get_formatter()._format_args(action, None)
except ValueError as e:
raise ArgumentError(action, str(e))
except TypeError:
#raise ValueError("length of metavar tuple does not match nargs")
raise ArgumentError(action, "length of metavar tuple does not match 
nargs")
# check the 'help' string
try:
self._get_formatter()._expand_help(action)
except (ValueError, TypeError, KeyError) as e:
raise ArgumentError(action, 'badly formed help string')

The 'except' clause may need to be changed to capture all (or just most?) of 
the possible errors in the format string.  Besides your error I can imagine 
'%(error)s` (a KeyError).  We also need to pay attention to the differences 
between Py2 and Py3 errors.

[issue21666] Argparse exceptions should include which argument has a problem

[paul j3]

paul j3 added the comment:

The ''_expand_help' method formats one action (argument) at a time, so it could 
issue an error message that includes that action's name.

The disconnect that you noticed arises because your bad 'help' parameter wasn't 
tested until is was used in a 'print_help'.

http://bugs.python.org/issue9849 asks for better testing of `nargs` (and 
`metavar`) values.  In the proposed patch, 'add_argument' creates a temporary 
HelpFormatter and tries to format a relevant portion of the help.  I suppose 
that test could be extended to test the 'help' parameter as well.

[issue21685] zipfile module doesn't properly compress odt documents

[Raimondo Giammanco]

Raimondo Giammanco added the comment:

SilentGhost, thank you for your reply but I am probably missing something with 
it. Maybe there is some misunderstanding because of my unclear report. Please 
let me sum up my point and excuse some repetitiveness

>From the documentation of .writestr:
``If given, compress_type overrides the value given for the compression 
parameter to the constructor for the new entry``
I believed to understand that .writestr would have used the same 
compression_type passed creating the `z' instance. So, having already passed 
ZIP_DEFLATED to the constructor, in my opinion, passing it again would have 
been an useless repetition.

However, as per your suggestion,I tried to explicitly pass ZIP_DEFLATED to 
.writestr too:

from zipfile import ZipFile, ZIP_DEFLATED
document = '/tmp/example.odt'
S2b, R2b = 'SUBST'.encode(), 'REPLACEMENT'.encode()
with ZipFile(document,'a', ZIP_DEFLATED) as z:
xmlString = z.read('content.xml')
xmlString = xmlString.replace(S2b, R2b)
z.writestr('content.xml', xmlString, ZIP_DEFLATED)

but to no avail: with and without passing ZIP_DEFLATED to .writestr the odt 
documents lose the feature explained in my first post

AFAICT, the only way to keep a fully functional odt document is not to compress 
it (no ZIP_DEFLATED at all), as cited in my previous post 

with ZipFile(document,'a') as z:
xmlString = z.read('content.xml')
xmlString = xmlString.replace(S2b, R2b)
z.writestr('content.xml', xmlString)

[issue21690] re documentation: re.compile links to re.search / re.match instead of regex.search / regex.match

[Julian Gilbey]

New submission from Julian Gilbey:

In re.rst, the re.compile documentation says:

   Compile a regular expression pattern into a regular expression object, which
   can be used for matching using its :func:`match` and :func:`search` methods,
   described below.

This results in linking to the re.match and re.search module functions instead 
of the regex.match and regex.search object methods.  I'm not sure what the 
correct replacement syntax is, presumably something like :meth:`~regex.match` 
and :meth:`~regex.search`.

Unfortunately, the test doesn't fail without the fix in, probably because the

[issue14203] bytearray_getbuffer: unnecessary code

[Kelley Nielsen]

Kelley Nielsen added the comment:

I have verified that this feature is unused in the source tree; in fact, there 
are no internal calls to bytearray_getbuffer() at all. The only thing 
bytearray_getbuffer() does with its second arg is pass it to 
PyBuffer_FillInfo(), which immediately checks it and passes 0 up the call stack 
if it is NULL. (A comment in PyBuffer_FillInfo() asks why -1 is not passed up 
instead; it's probably to distinguish this feature from the error condition 
handled in the immediately following conditional block.)

There are potentially other issues stemming from this legacy feature in 
bytearray_getbuffer(), PyBuffer_FillInfo(), and elsewhere. The maintainers may 
see fit to open tickets on these issues as well.

There's more relevant commentary on the feature here:

[issue18141] tkinter.Image.__del__ can throw an exception if module globals are destroyed in the wrong order

[Jan Kanis]

Jan Kanis added the comment:

The 3.3 branch is not affected as the f0833e6ff2d2 changeset was never merged 
into that branch.

In the default branch the exception stops appearing after commit 79e2f5bbc30c: 
"Issue #18214: Improve finalization of Python modules to avoid setting their 
globals to None, in most cases." This changeset is also part of the current 3.4 
tip (19172062e5c0), so 3.4 tip does not display the buggy behaviour. Judging by 
the commit message, that commit also supersedes the attached patch as it at 
least prevents the visible symptoms. I am not sure if there still might be a 
deeper issue that is hidden by the changeset as Terry suggested.

[issue12594] Docs for "Using Python on a Macintosh" needs to be updated

[Ned Deily]

Ned Deily added the comment:

Thank you for the patch, Yuly!  You've made some good improvements to the 
current page.  Because the current section is so old and out-of-sync with 
current practices (as you've noted in your changes) and with the nuances of 
Python on OS X, a more comprehensive restructuring is needed.  I don't think 
that trying to refine the section interactively is going to be an efficient 
process but I will definitely use your suggested changes as a basis.  I assume 
you have signed (or will be signing) the PSF contributor agreement.  Thanks 
again!  P.S. When submitting patches, don't forget to run patchcheck first 
(https://docs.python.org/devguide/patch.html#generation).  It will detect and 
fix trailing whitespace in lines that would otherwise prevent a patch from 
being committed in the main cpython hg repo.

added try finally as suggested by berkerpeksag. make patchcheck still works and 
all test cases still pass. did not use the test.support.swap_attr context

[Benjamin Peterson]

Benjamin Peterson added the comment:

The original bug (junk in various doc strings) has been fixed, but I think the 
positional argument "/" syntax still needs docs. It's a little tricky because 
"/" is not actually valid syntax; it's just for documentation signatures.

[issue21666] Argparse exceptions should include which argument has a problem

[Glenn Linderman]

Glenn Linderman added the comment:

Yes, I hope someday the parse_intermixed_args patch can be released... but I 
know it is not relevant to this issue.

I was aware of the %(substitution_variables) in the default help formatter, but 
I (1) goofed and entered % without escaping it (2) was surprised at how 
unhelpful the Traceback was at isolating the problem.

Happily, my code had only a few instances of %) so I was able to isolate it 
fairly quickly, but the error report certainly shows up at quite a distance 
(execution-wise) from the location of the source bug.

I haven't looked at the source for the HelpFormatter code: if it concatenates 
all the help text and then does substitutions en masse, then it would be 
difficult to isolate the error to a particular argument. If, on the other hand, 
it loops through the help text for each argument, doing the substitutions, and 
later formatting and concatenating, then surrounding the substitution attempt 
with a try: block so that the name of the argument with the faulty help text 
could be reported, that would be a big help to this situation, at little cost.

now garbage-collected at shutdown."

I will try bisecting the 3.3 branch to se where the bug stops appearing.

[issue21687] Py_SetPath: Path components separated by colons

[eryksun]

eryksun added the comment:

A Windows path uses ":" after the drive letter, e.g. "C:\\Windows", so the 
delimiter is a semicolon on Windows. Other platforms use a colon.

CPython uses DELIM, which is defined in osdefs.h. This header isn't included by 
Python.h.

[issue8576] test_support.find_unused_port can cause socket conflicts on Windows

[Paul Moore]

Paul Moore added the comment:

TBH, I don't think I ever took this any further. As noted, the earlier patches 
fixed the failures I was hitting.

It looks like Python 3.4 now has *two* definitions of find_unused_port, in 
test.test_support and in test.support. And test_asyncio and test_ftplib also 
use the function now.

[issue21666] Argparse exceptions should include which argument has a problem

[paul j3]

paul j3 added the comment:

First, 'parse_intermixed_args' on stack is not relevant.  It's from an 
unreleased patch that we worked on.

What matters is the 'print_help', invoked probably with a '-h'.

The error message that normally specifies the problem argument is produced by 
ArgumentError.  The HelpFormatter does not raise such an error.  ArgumentError 
is usually used for parsing errors; this is a formatting one.  It's not 
produced by faulty commandline values.

If you must put strings like '%)` in the help line, use RawTextHelpFormatter.  
Otherwise HelpFormatter assumes the help line has valid format expressions like 
'%(default)s'.

Or you could write your own HelpFormatter subclass with a modified 
'_expand_help' method, one which wraps the 'self._get_help_string(action) % 
params' in a 'try' block.  Probably too draconian a measure for a rare problem. 
:)  

It's an interesting problem, but I don't think it warrants any code changes.

[issue9012] Separate compilation of time and datetime modules

[Mark Lawrence]

Mark Lawrence added the comment:

msg111078 refers to r82035 for Visual Studio 2005 (VC8) builds.  Given that 
http://code.activestate.com/lists/python-dev/131023/ refers to VC14 for 3.5 can 
we close this as out of date?

[issue12673] SEGFAULT error on OpenBSD (sparc)

[Remi Pointel]

Remi Pointel added the comment:

For your information, this bug has been fixed in OpenBSD and the developper has 
contacted the NetBSD developper:
http://marc.info/?l=openbsd-tech&m=140209064821540&w=2

So I think we could close this issue because it's a system issue, not Python.

[issue15707] PEP 3121, 384 Refactoring applied to signal module

[Mark Lawrence]

Mark Lawrence added the comment:

PEP 384 is listed as finished while 3121 is accepted so what if anything needs 
to be done here?  I've checked https://docs.python.org/devguide/experts.html 
and nobody is listed against the signal module.  The patch is C code which I 
don't have the knowledge to comment on, sorry about that.

[issue21687] Py_SetPath: Path components separated by colons

[Florian Walch]

New submission from Florian Walch:

The documentation for Py_SetPath [1] states:

> The path components should be separated by semicolons.

I believe this should not say "semicolons", but "colons"; the default path as 
output by Py_GetPath is separated by colons.

[issue18141] tkinter.Image.__del__ can throw an exception if module globals are destroyed in the wrong order

[Jan Kanis]

Jan Kanis added the comment:

I tried changing the last block in turtulemodule/__init__.py to

if __name__ == '__main__':
demo = DemoWindow()
print("ENTERING mainloop")
demo.root.mainloop()
print("Bye")

but that does not solve the problem:

> python3 -m turtledemo
ENTERING mainloop
Exception ignored in: >
Traceback (most recent call last):
  File "/home/jan/test/lib/python3.4/tkinter/__init__.py", line 3330, in __del__
TypeError: catching classes that do not inherit from BaseException is not 
allowed

so still the same error. (Although it is probably still good to make that 
change.)

Tested on cpython revision dfcb64f51f7b, so the same as I originally made the 
bugreport from.

I like the idea of a select and/or multiselect for 3.5. As a 
new feature, it cannot go into 3.4.

[issue21667] Clarify status of O(1) indexing semantics of str objects

[Nick Coghlan]

Nick Coghlan added the comment:

I've merged the character->code point clarifications, without the 
implementation detail section.

For the time being, that leaves "doesn't provide O(1) indexing of strings" as 
the kind of discrepancy that often makes an appearance in "differences from the 
CPython reference implementation" section that many alternative implementations 
include.

[issue21685] zipfile module doesn't properly compress odt documents

[SilentGhost]

SilentGhost added the comment:

Raimondo, the documentation clearly states that the compression method is 
either inherited from ZipInfo instance (when that one is passed) or set to 
ZIP_STORED otherwise. Since you're not passing ZipInfo instance, but the string 
(as the first argument to .writestr), therefore the compression method is set 
to ZIP_STORED. If you're not set it to ZIP_DEFLATED explicitly, it would work 
as you expect it. In either case, this behaviour is in accordance with the 
documentation.
