[issue22621] Please make it possible to make the output of hash() equal between 32 and 64 bit architectures

[Georg Brandl]

Georg Brandl added the comment:

While I can feel your pain regarding the use case you describe, I don't think 
this has enough general value to add to CPython.  It is not really related to 
PYTHONHASHSEED, since we never made guarantees about hash values being stable 
across platforms and Python versions.  PYTHONHASHSEED was introduced to address 
backwards compatibility for the rare cases where stable hash values are 
required within a platform/version combination.

Without knowing anything about your libraries, would it not be possible to 
create a stable representation within the test case for comparison purposes, 
without having to write the unstable result to a file and then parsing it?  
That should be acceptable, given that creating and manipulating those graphs 
will probably also take significant time in the first place.

[issue17667] Windows: build with "build_pgo.bat -2" fails to optimize python.dll

[Anselm Kruis]

Anselm Kruis added the comment:

It's indeed a very low priority issue.

You mention VS2008 and VS2010 PGO compiler bugs. I'm aware of the VS 2010 bugs, 
but I didn't observe any VS 2008 PGO bug with Python 2.7. Are you aware of any 
publicly available bug reports?

About the black/white list. I started with a black list, but then I switched to 
a white list for the following reason: the goal of running the test suite is to 
generate a reasonable profile. It is not a goal to test anything. Therefore 
both white list and black listing is possible.
I consider it more likely that a newly added test breaks the PGO build than 
that an existing test will be modified in a breaking way. Therefore I consider 
the while list superior for this particular application.

But as you already stated, it is low prio.

[issue22620] pythonw does not open on windows 8.1 x64

Maybe the best way is to put a shortcut to idle in the main directory where the

[issue22621] Please make it possible to make the output of hash() equal between 32 and 64 bit architectures

[josch]

New submission from josch:

I recently realized that the output of the following is different between 32 
bit and 64 bit architectures:

PYTHONHASHSEED=0 python3 -c 'print(hash("a"))'

In my case, I'm running some test cases which involve calling a Python module 
which creates several hundred megabyte big graphs and other things. The fastest 
way to make sure that the output I get is the same that I expect is to just 
call the md5sum or sha256sum shell tools on the output and compare them with 
the expected values. Unfortunately, some libraries I use rely on the order of 
items in Python dictionaries for their output. Yes, they should not do that but 
they also don't care and thus don't fix the problem.

My initial solution to this was to use PYTHONHASHSEED=0 which helped but I now 
found out that this is limited to producing the same hash within the set of 32 
bit and 64 bit architectures, respectively. See above line which behaves 
different depending on the integer size of architectures.

So what I'd like CPython to have is yet another workaround like PYTHONHASHSEED 
which allows me to temporarily influence the inner workings of the hash() 
function such that it behaves the same on 32 bit and 64 bit architectures. 
Maybe something like PYTHONHASH32BIT or similar?

If I understand the CPython hash function correctly, then this environment 
variable would just bitmask the result of the function with 0x or cast 
it to int32_t to achieve the same output across architectures.

Would this be possible?

My only alternative seems to be to either maintain patched versions of all 
modules I use which wrongly rely on dictionary ordering or to go to great 
lengths of parsing the (more or less) random output they produce into a sorted 
intermediary format - which seems like a bad idea because the files are several 
hundred megabytes big and this would just take very long and require additional 
complexity in handling them compared to being able to just md5sum or sha256sum 
them for the sake of checking whether my test cases succeed or not.

[issue21986] Idle: disable pickleability of user code objects

[Terry J. Reedy]

Terry J. Reedy added the comment:

I agree that a test for dumps would be a good idea.  Ditto for hundreds of 
other untested functions.  I don't see this one as a priority.

PyShell imports non-idlelib modules, including re, before idlelib modules, such 
as rpc.  So the re addition is there, though I strongly doubt that compiled 
regexs are every sent to the user process.  Since about 10 different messages 
of different types are sent as part of startup, the fact that Idle does start 
is strong evidence that dumps and much of the rest of rpc is ok.  I would start 
a test of rpc by documenting the protocol and listing the messages types so at 
least one of each could be tested.

[issue11664] Add patch method to unittest.TestCase

[Martin Panter]

Martin Panter added the comment:

[padding to avoid UTF-8 error with bug tracker]

See also Issue 22374, where an equivalent of “patch.object” is suggested as an 
example context manager for the “contextlib” documentation.

If we added a plain function or context manager rather than a new TestCase 
method, it might avoid the worries about bloating the API. Then it could be a 
generic thing for any kind of testing, and not coupled with the “unittest” 
framework.

About cleanup functions more generally, I think they already tie in well with 
the TestCase.addCleanup() API. Perhaps it could handle general context managers 
as well though, by inheriting an ExitStack.enter_context() method or providing 
an ExitStack attribute.

Would you be ok with it going into 2.7.10? The biggest argument in favor of

them.

[issue11664] Add patch method to unittest.TestCase

[Ezio Melotti]

Ezio Melotti added the comment:

I'm -0.5 on this as well, and agree that we should try to keep the TestCase API 
small.

On one hand, a patch method available without extra imports would be handy, and 
having this as a generic function/method in unittest seems more natural to me 
than having it in unittest.mock.  On the other hand, adding it to unittest has 
downsides as well: it increases API complexity, adds duplication and possibly 
confusion (people might wonder if they should use TestCase.patch or 
unittest.mock.patch, and if there are any differences).  Adding both .patch and 
.patch_object makes things even worse.

[issue11664] Add patch method to unittest.TestCase

[Robert Collins]

Robert Collins added the comment:

FWIW I'd really like to be reducing the TestCase API not extending it - 
particularly since there are lots of good convenient ways of doing this already 
(not least mock.patch/mock.patch.object).

So I'm -0.5 on adding this, as I don't see it adding value. That said, I'll 
happily review for correctness if there is consensus that we want it.

Relatedly I'd like to find some way to let regular functions tie into cleanups 
automatically, so that we don't need helpers like this *at all*. That probably 
needs a PEP though.

Right. I prefer your solution because it's much simpler, it doesn't make 
traceback less usable at exit, and it doesn't need to make assumption on the 
Python status.

Here is a patch implementing this idea with an unit test.

[issue20567] test_idle causes test_ttk_guionly 'can't invoke "event" command: application has been destroyed' messages from Tk

[Terry J. Reedy]

Terry J. Reedy added the comment:

You left this issue number off your tkinter test updates, such as f6f098bdb843. 
 By using .update_idletasks instead of .update, are you assuming that their are 
no user events, or that they should be ignormed?

I was wondering whether it would be Ok, if not a good idea, to run tests, and 
maybe Idle itself, with NoDefaultRoot.  I see that is already done for tkinter 
tests. I cannot use exactly the same design as AbstractTkTest since I sometimes 
do other things in setUp/tearDownClass, but I could define create_test_root() 
and delete_test_root() functions in a support file.

[issue22390] test.regrtest should complain if a test doesn't remove temporary files

[STINNER Victor]

STINNER Victor added the comment:

> This allow other tests which leaks the same file to be reported too.

I don't understand your answer. The "fn.startswith(support.TESTFN)" test is not 
used in get_files().

If I understood correctly, your patch changes two things:

- it now reports files created for tests but not deleted (purpose of this issue)
- it removes more files than before

I don't understand why you want to remove more files than before. You may open 
a different issue, or at least explain the rationale.

I never see any forgotten test file after running tests, so I don't see why you 
are worried because of them. And with your first patch, we will now noticed 
forgotten files, so we can just fix tests.

[issue21603] IDLE: Document SaveAs extension display on Mac

[Ned Deily]

Ned Deily added the comment:

If Raymond concurs that either unchecking the Hide Extensions option or 
checking the Show All Filenmame Extensions preference solves the problem for 
him, we should just close this issue.  In this particular case, the file is 
actually saved with a .py extension; it's just that the extension part is not 
displayed in the standard OS file dialogs.  It is visible via, say, "ls" in a 
UNIX shell.  This is standard OS X application behavior and caters to two 
different styles of file interaction.  All OS X applications that use the 
standard file save dialogs work this way.  See, for example, 
http://support.apple.com/kb/PH13920?viewlocale=en_US&locale=en_US.

[issue20567] test_idle causes test_ttk_guionly 'can't invoke "event" command: application has been destroyed' messages from Tk

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

These messages are produced because there are non-handled events of destroyed 
root widget. They are handled when update() is called for other root widget. To 
get rid of them you should call update_idletasks() before destroying root 
widget.

Committed.  I changed the urls as suggested by Antoine.  I also added a link to 
the test pypi page, though I'm not sure what I did is exactly what Antoine had 
in mind.

It can raise an exception in rare cases. The manual of pipe mentions this. The 
code of posix_popen() contains error handling.

> FYI os.popen() now calls subprocess...

Not in 2.7.

May be, but this is different issue, which is not related to this issue. If 
os.popen should be replaced with subprocess, it should be done even without 
applying the patch of this issue. Please open new issue.

However the recent Shellshock story affects only users of platforms which use 
bash or zsh as system shell (are there any?).

> subprocess now has a convinient subprocess.DEVNULL.

Not in 2.7.

Berker: the patch doesn't apply cleanly any more.  Also, about the 
test_bad_timezone modification...what about the previous check that the tzname 
wasn't in UTC/GMT?  Isn't that still needed?  Or perhaps better yet, an 
additional @run_with_tz decorator?  (Note that I don't really *understand* this

[issue22618] urllib.parse.parse_qsl different results after urllib.parse.unquote

[Alex Vaystikh]

Alex Vaystikh added the comment:

It is much clearer after your insight:
- I wasn't aware that 'parse_qs' unquotes values. That's most helpful!
- I had no idea what 'keep_blank_values' were before your example, but now it 
couldn't be more obvious. I know that adding that example to docs would've 
helped me a lot! Maybe others?

Thank you for the help!

[issue22616] Allow connecting AST nodes with corresponding source ranges

[R. David Murray]

R. David Murray added the comment:

OK, reading the followon links just added to issue issue 10769, it seems clear 
you don't need to advocate for the idea of supporting external tools, there 
seems to be consensus agreement for that.  So now it is down to specific 
proposals and patches.  And reviews of patches, those are equally important :)

[issue17293] uuid.getnode() MAC address on AIX

[STINNER Victor]

STINNER Victor added the comment:

+cmd = 'LC_ALL=C %s %s 2>/dev/null' % (executable, '-ia')

It's safer to use the subprocess module instead of using a shell (see the 
recent Shellshock story) to change the environment variables and to redirect 
stderr. subprocess now has a convinient subprocess.DEVNULL. So it's something 
like:

env = os.environ.copy()
env['LC_ALL'] = 'C'
process = subprocess.Popen([executable, '-ia'], stderr=subprocess.DEVNULL)
...

Why is that a different issue?
The code you *add in this patch* uses os.popen, why not use subprocess instead?

Furthermore, the code catches OSError when calling popen(), but

[issue22618] urllib.parse.parse_qsl different results after urllib.parse.unquote

[R. David Murray]

R. David Murray added the comment:

Isn't it obvious that you have to parse before you unquote?  That's the purpose 
of quoting, after all.  I suppose that is one of those "beginner mind" things 
that is obvious only because I'm an experienced programmer...and that there are 
web servers that do it wrong. 

The docs could definitely use some improvement, since they don't mention that 
parse_qs automatically unquotes the values...it is implicit in the fact that 
urlencode with doseq=true is the inverse, and it encodes them, but it should be 
made explicit.

You also might want to take note of the 'keep_blank_values' attribute, which 
could also use a doc improvement (it isn't obvious from the text what 'blank 
values' are):

>>> parse_qs('a=1&b=2&b=1&a%3Donly_appears_after_unquote', 
>>> keep_blank_values=True)
{'a': ['1'], 'b': ['2', '1'], 'a=only_appears_after_unquote': ['']}

[issue22616] Allow connecting AST nodes with corresponding source ranges

[R. David Murray]

R. David Murray added the comment:

The "python develop team" is a group of volunteers.  What you need to do to 
move this forward is to work on patches (or polishing patches, in the case of 
issue 16806) for open issues for which there has been no objection, and build a 
consensus for fixing the issues for which there has been objection.

Based on the issue 10769 discussion, it sounds like it would be worthwhile to 
go to python-ideas and advocate for the position that the ast parser should be 
enhanced for the kind of use cases you are talking about.  It is possible a PEP 
would be required, but it is also fairly likely that one will not be.

Personally I'm in favor of supporting such use cases, but I'm not involved in 
maintaining any of the relevant code nor do I have an interest in getting 
involved at this time.

[issue5700] io.FileIO calls flush() after file closed

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

Yet one related bug is that flush() isn't called at all if the file was opened 
with closefd=False.

>>> import io, os
>>> class MyIO(io.FileIO):
... def flush(self):
... print('closed:', self.closed)
... 
>>> fd = os.open('test.out', os.O_WRONLY|os.O_CREAT)
>>> f = MyIO(fd, 'wb', closefd=False)
>>> f.close()

The proposed simple patch fixes both bugs.

[issue11664] Add patch method to unittest.TestCase

[Julian Berman]

Julian Berman added the comment:

My opinion is already here re: patch vs patch.object, so I won't repeat it, but 
@Michael, if you really want .patch, are you open to adding .patch_object as 
well?

(Regardless, thanks for working on this Julien.)

[issue21986] Idle: disable pickleability of user code objects

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

It would be good to add a test of rpc.dumps().

Current code copies copyreg.dispatch_table at the moment of rpc import. But it 
can be changed later and these change will not affect private copy. For example 
the re module adds pickleability of compiled regex patterns. I think the use 
of ChainMap is more safe solution.

[issue22616] Allow connecting AST nodes with corresponding source ranges

[Edward K. Ream]

Edward K. Ream added the comment:

I urge the Python development team to fix this and the related bugs given in 
the Post Script. The lack of an easy way of associating ast nodes with text 
ranges in the original sources is arguably the biggest hole in the Python api.

These bugs have immediate, severe, practical consequences for any tool that 
attempts to regularize (pep 8) or beautify Python code.

Consider the code for PythonTidy:
http://lacusveris.com/PythonTidy/PythonTidy-1.23.python

Every version has had bugs in this area arising from difficult workarounds to 
the hole in the API.  The entire Comments class is a horror directly related to 
these issues.

Consider Aivar's workaround to these bugs:
https://bitbucket.org/plas/thonny/src/8cdaa41aca7a5cc0b31618b6f1631d360c488196/src/ast_utils.py?at=default
See the docstring for def fix_ast_problems.  This is an absurdly difficult 
solution to what should be a trivial problem.

It's impossible to build reliable software using such heroic hacks.  The 
additional bugs listed below further complicate a nightmarish task.

In short, these bugs are *not* minor little nits.  They are preventing the 
development of reliable source-code tools.

Edward K. Ream

P.S. Here are the related bugs:

http://bugs.python.org/issue10769
Allow connecting AST nodes with corresponding source ranges

http://bugs.python.org/issue21295
Python 3.4 gives wrong col_offset for Call nodes returned from ast.parse

http://bugs.python.org/issue18374
ast.parse gives wrong position (col_offset) for some BinOp-s

http://bugs.python.org/issue16806
col_offset is -1 and lineno is wrong for multiline string expressions

[issue21603] IDLE: Document SaveAs extension display on Mac

[Terry J. Reedy]

Terry J. Reedy added the comment:

(I moved the commit message)

I am assuming that Ned is correct.  I think we should start documenting system 
peculiarities like this.  I changed the title and will leave this open for this 
purpose.

[issue15363] Idle/tkinter ~x.py 'save as' fails. closes idle

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

Interesting, that "save as" ./~x.py works when the "~x.py" file exists and 
doesn't work (press the "Save" button has no any effect at all, even doesn't 
close a dialog) when it does not exist on Linux.

[issue22614] Idle: problem in PyShellEditorWindow.color_breakpoint_text

[Terry J. Reedy]

Terry J. Reedy added the comment:

Makes sense now. Large file relative to machine speed + quick close click = 
close (at least to point of destruction of self.text) before initialization is 
complete.  Hence continued initialization fails. Yes, when closing crashed in 
Multicall, would not see initialization after close error.

Switch to .update_idletasks ignores close event, hence initialization gets to 
complete without error.  Do we want to do that?  I think not.  If one tries to 
edit gigabyte file, idle/tk will probably hang and one very well might want 
close event handled.  We could instead wrap test.tag_config with try: except 
AttributeError.  Original authors assumed this would never happen, but its 
occurrence seems like a rare but legitimate possibility that should be allowed 
for.

After sleeping, I will try to reproduce on my fast machine using Windows copy 
command.  3k EditorWindow.py is colorized too fast.

[issue21603] IDLE SaveAs drops the extension in the prompted filename

[Ned Deily]

Ned Deily added the comment:

Thanks, Raymond.  Upon further investigation, I think you are running into a 
user-wide behavior of OS X rather than specifically a Tk or IDLE issue.  By 
tradition and by default, OS X tries to hide file extensions in file Open or 
Save dialogs; this dates back to the days of Classic Mac OS when there was no 
concept of file extensions.  There is a (non-obvious) user preference in the OS 
X Finder's preferences (Finder -> Preferences -> Advanced -> Show all filename 
extensions) that appears to control whether extensions are displayed by default 
in standard Open and Save dialogs in all applications, not just the Finder.  
(This is with OS X 10.9.x; I believe recent earlier systems behave similarly 
although the details might be slightly different).  When the preference is 
unchecked (the default), then in "Save As" dialogs (in IDLE and other apps) a 
"Hide Extension" option box appears in the lower-left corner of the "Save As" 
popup window and, if enabled, the extension is not displayed as pa
 rt of the file name.  Unchecking the "Hide Extension" box causes the extension 
to appear.  If the Finder "Show all filename extensions" advanced preference is 
checked, then the "Hide Extension" box does not appear on the "Save As" popup 
and the extension is always displayed.  I always have the "Show all filename 
extensions" preference checked so I forgot it was there and its effect on all 
file dialogs.  My guess is that you will want to have it enabled as well and 
then you should always see extensions.

Note that for the initial "Save" of a file in IDLE (as opposed to a "Save As"), 
Python 3.4 supplies a default extension of ".py" which is displayed regardless 
of the Finder preference setting; but Python 2.7 up through the current 2.7.8 
does not supply the default.  That changes in 2.7.9 as Terry has recently 
backported the 3.x change to 2.7 (Issue4832, although the commit message for 
the backport appears in Issue3832 due to a typo).
