[issue33705] Unicode is normalised after keywords are checked for

Possibly the correct term is canonicalisation rather than normalisation, 
although I think the two are interchangeable.

[issue33705] Unicode is normalised after keywords are checked for

[Steven D'Aprano]

New submission from Steven D'Aprano :

There is a loophole in the Unicode normalisation which allows the creation of 
names matching keywords.

class Spam:
locals()['if'] = 1

Spam.퐢퐟# U+1D422 U+1D41F
# returns 1

Those two characters are 'MATHEMATICAL BOLD SMALL I' and 'MATHEMATICAL BOLD 
SMALL F'. They ought to be normalised to "if", which is a keyword.

Of course Spam.if is a syntax error, and I believe Spam.퐢퐟 ought to be as well.

Another example:

py> globals()['for'] = 2
py> 퐟or
2



I also asked about this here:

[issue33704] python 3.7 and python 3.8 stable release

[Ned Deily]

Ned Deily  added the comment:

We have just updated the release schedule for Python 3.7 to include 3.7.0b5, 
now available.  The 3.7.0 release candidate is now planned for 2018-06-11 with 
3.7.0 final to follow on 2018-06-27.  We expect 3.7.0 to be adopted quickly but 
3.6.x will be still supported for some time in the major distributions.  Python 
3.8 is now in the early stages of development, with a final release currently 
planned for 2019-10 although that may change.  Information about current Python 
release plans are contained in and kept up-to-date in their respective PEPs:

3.6 https://www.python.org/dev/peps/pep-0494/
3.7 https://www.python.org/dev/peps/pep-0537/
3.8 https://www.python.org/dev/peps/pep-0569/

[issue33704] python 3.7 and python 3.8 stable release

[Saba Kauser]

New submission from Saba Kauser :

Hi,
I am planning to make new release of python ibm_db driver and I wanted to know 
the stable versions of python beyond python 3.6.

I can see python 3.8 marked as "in development" and I do read that python 
3.7.0b4 is the final planned beta release preview. Would this mean that I 
cannot consider python 3.7 and python 3.8 for my next release and I would build 
only when these are marked stable.

Thank you!
Saba.

[issue33703] Object deletion and re-creation points to same attribute if attribute is a dictionary.

[Nitin Bhojwani]

New submission from Nitin Bhojwani :

I observed a strange behaviour while working on a module.
This bug is present in multiple python version so seems it is related to 
core-interpreter.

Behaviour can be reproduced by:
1. Create an object and in __init__ of class, we define a dictionary attribute 
to that object.
2. After that we change that attribute, like assign any key-value(s) to that 
attribute.
3. Delete the object.
4. recreate the object.
5. If you check, this new object's same attribute(dictionary) is same old 
attribute which was pointed by the older object.

This is a behavioural bug, as once delete is performed on an object the whole 
object and it's (attributes') references must be removed.

I can demonstrate this using a test from unittest, in which I put instance 
creation in setUp phase, instance deletion in tearDown phase and run same test 
multiple times. The result is different each time.

The zip file contains ngraph.py which defines a class and test_util.py which 
runs test against it.
Unzip and execute as:

python test_util.py #2.7.10
python3 test_util.py #3.6.3

[issue33702] Add some missings links in production lists and a little polish

[Andrés Delfino]

New submission from Andrés Delfino :

There are some missing links in production lists (try, with, from __future__ 
import), and function and coroutines definitions production lists have too long 
lines.

PR fixes this and does some polish on whitespace.

[issue33500] Python TKinter for Mac on latest 2.7.15 still extremely slow vs Windows

[Michael Romero]

Michael Romero  added the comment:

* What version of macOS are you using? "Is fully patched" the latest High 
Sierra?
- I've tried the version bundled with MacOS fully patched high sierra, as well 
as versions downloaded from python.org, Intel, and ActiveState.  They all 
demonstrate the slowness.

* Which variant of the Python 2.7.15 installer did you use? 
- I used the 64-bit only installer from python.org during one test.  However, 
all versions I've tried on MacOS seem to demonstrate the issue.

* Did you install ActiveState Tcl/Tk (check if there is a Tk.framework
  in /Library/Frameworks)? If so, which version?
- I used the bundled version of ActiveState Tcl/Tk that came with the 64-bit 
only installer. I have also experimented with alternate versions of python that 
use a Tcl/Tk externally.  "8.5" is the version I see on my system now.

[issue33500] Python TKinter for Mac on latest 2.7.15 still extremely slow vs Windows

[Michael Romero]

Michael Romero  added the comment:

I don't have a minimal failing example as is being requested. What I do have is 
the smallest version of the code published by Berkeley's AI course that I could 
find that allows easy demonstration of the issue.  "python pacman.py" is enough 
to demonstrate the latency difference between the MacOS and Windows versions of 
Python. 

The specific calls causing the program to run slowly on MacOS I leave to this 
team to determine / resolve.

[issue33532] test_multiprocessing_forkserver: TestIgnoreEINTR.test_ignore() fails on Travis CI

[STINNER Victor]

STINNER Victor  added the comment:

Davin, Antoine: any idea on this bug?

I ran the full test suite and test_multiprocessing_forkserver in parallel in a 
Trust VM, but I failed to reproduce the bug.

I did a similar test in a Ubuntu Trusty docker container: again, I'm unable to 
reproduce the bug.

An Ubuntu Trusty docker container is supposed to be as close as possible to 
Travis CI, except that my laptop doesn't have 48 CPUs.

[issue33700] [doc] Old version picker don't understand language tags in URL

[Ned Deily]

Ned Deily  added the comment:

> Fix in the 3.5 branch which is not allowed as the branch is in "security 
> only" mode.

I think you could appeal to the 3.5 Release Manager that this should go in.  
Since the 3.5 docs are only rebuilt manually these days (I think), in the worst 
case the current 3.5 on-line docs would not reflect the change until the next 
3.5.x security release.

[issue33590] sched.enter priority has no impact on execution

[Matthew Fisher]

Matthew Fisher  added the comment:

> I did look at the code :-)

I also looked at the code.  I had to do so to understand why the example output 
was not "as expected."  ;)

> I don't agree about the example in the documentation, it is a clear
> demonstration about how to use the API in general and AFAIK is not
> intended to show how priorities work.

Although I came to the same conclusion as you regarding both the fact and the 
reason the output was correct, I respectfully disagree that the example is 
clear.  It is not.  Yes, the example, as written, is intended to demonstrate 
the API -- which consists of several functionalities *including priority*.  If 
this were not so, the example would not be passing different priority values 
with the same delay value.

I suggest re-opening this issue as a documentation bug and modifying the 
example to use enterabs instead of enter.

Respectfully,
M Fisher

[issue33698] `._pth` does not allow to populate `sys.path` with empty entry

[Steve Dower]

Steve Dower  added the comment:

If your ._pth includes `import site`, then including a blank line in a 
`anything.pth` file should add the entry.

Alternatively, if you can add "import sys; sys.path.insert(0, '')" to the start 
of your code that depends on it you should be fine.

[issue33700] [doc] Old version picker don't understand language tags in URL

[Julien Palard]

New submission from Julien Palard :

In the old version picker used back in 3.5 [1], the function patch_url was 
patching using the following regex:

var url_re = /\.org\/(\d|py3k|dev|((release\/)?\d\.\d[\w\d\.]*))\//,

which does not expects a language tag.

This means, for example, that being on 
https://docs.python.org/fr/3.5/library/__main__.html and switching to 3.6 will 
fail (but the reverse will succeed as the implementation of the switcher in 3.6 
understands the language tag).

I see two potential fixes:

- Fix in the 3.5 branch which is not allowed as the branch is in "security 
only" mode.
- Add a rule, nginx-side, to fix the misconstructed URLS (looking like 
/3.6/fr/3.5/library/...) redirectin g them to the right place.

Other ideas and feedback welcome.

[issue33479] Document tkinter and threads

[Mark Roseman]

Mark Roseman  added the comment:

I've made some changes to what Ivan started, which you can find here: 
https://github.com/roseman/cpython/tree/tkinter_docs

The first two commits are minor updates/improvements not really related to 
threading, and I suspect are uncontroversial. 

The last commit rewrites the thread model section. The main focus is on how 
things work in practice, and to eliminate what I previously referred to as 
"fighting" between the two models. 

It explains how Python and Tcl differ on threads, the mappings between threads 
and interpreters, etc.

It plays down the comparison to other GUI toolkit event models. It still 
highlights the difference for people familiar with them. It doesn't try to 
teach both models for those who don't know either (which includes those who may 
not have done much if any GUI programming) since that is extraneous to their 
present needs. It talks simply about why event handlers blocking is a bad 
thing. It avoids what I think are unnecessary details about Tcl in this context.

There is then an area for special cases that highlight the various actual 
trouble spots when it comes to threads, what can cause them, and how to avoid 
them. 

I hope this covers the real issues without overly complicating things. Any 
thoughts?

I've created a pull request for this based on Éric's patch in 2010.  I 
attempted to incorporate the changes from #29755 into the new functions and 
tests.  I believe these changes take care of items 1 and 2 from msg122439.

I haven't tried to address item 3 in msg122439 yet.

Since this is already a large change, item 4 in msg122439 might be better as 
its own issue.

If this is actually an issue, and not just a documentation lapse I can create a

[issue33698] `._pth` does not allow to populate `sys.path` empty entry

[Vladimir Chebotarev]

New submission from Vladimir Chebotarev :

Moving from bpo-29326

Hi Steve.

I'll try to explain what is my motivation.

I need a reliable way to run Python (not matter embedded or not) in isolated 
mode, but still having current directory in `sys.path` (empty entry).

Ironically I could misuse normal mode to simulate isolated mode with specified 
%PYTHONPATH% (which is not much handy, by the way), but hiding Windows Registry 
keys would look pretty hard (it is impossible to make a bat/cmd wrapper). 
Possibility to search %PYTHONPATH% in HKLM entries makes it even worse.

Empty entry in `sys.path` is a extremely popular thing, and many software 
depend on it. It looks like a bug that isolated mode cannot support such entry.

# How would I fix it.

Possibly we should allow another keyword for adding an empty entry (like we 
have an exclusion for `import site`).

Ideas are appreciated.

[issue29326] Blank lines in ._pth file are not ignored

[Steve Dower]

Steve Dower  added the comment:

The python._pth file generated for the embeddable distribution includes ".", 
which allows you to import from the dist directory. The blank line should be 
ignored.

If you want to misuse the embeddable distribution by not restricting its search 
paths, delete the ._pth file.

> We can remove the socket buffers size manipulation at all without any problem.


When I tried to do that I think I was having more failures with that test. But 
really up to you.

[issue33694] test_asyncio: test_start_tls_server_1() fails on Python on x86 Windows7 3.7 and 3.x

[Andrew Svetlov]

Andrew Svetlov  added the comment:

I used SNDBUF to enforce send buffer overloading.
It is not required by sendfile tests but I thought that better to have 
non-mocked way to test such situations.
We can remove the socket buffers size manipulation at all without any problem.

[issue33694] test_asyncio: test_start_tls_server_1() fails on Python on x86 Windows7 3.7 and 3.x

[Yury Selivanov]

Yury Selivanov  added the comment:

I can't reproduce test_start_tls_server_1 fails when I do (screenshot attached)

1. run test_asyncio
2. run test_asyncio.test_sslproto
3. run test_asyncio.test_sslproto -m test_start_tls_server_1

I run them in Windows 7 VM on Mac OS.

All other tests pass fine for me except 
test_sendfile_close_peer_in_the_middle_of_receiving.  Andrew, please look at 
this, this is your test, and I'm not sure I follow why we use SNDBUF at all. 
IMO it should be possible to write a test without using that (or if not, maybe 
time to use mocks).

With regards to start_tls tests -- I give up, I don't have time to look into 
this before 3.7.0.  I suggest to mask the test on the specific win buildbot it 
crashes on and fix it before 3.7.1 (or maybe when Windows users come up with a 
reliable way to reproduce the bug).
