[issue37824] IDLE: Handle Shell input warnings properly.

[Terry J. Reedy]

Terry J. Reedy  added the comment:

The new items can be new issues, with 6 maybe the highest priority.  Currently
:1: DeprecationWarning: invalid escape sequence \e
becomes
Warning (from warnings module):
  File "", line 1
'\e'
DeprecationWarning: invalid escape sequence \e

For both Shell and Editor input, the Warning Line is not really needed.  For 
Shell, the fake filename is not needed, nor is the line # and line if somehow 
otherwise marked.

[issue37824] IDLE: Handle Shell input warnings properly.

[Terry J. Reedy]

Terry J. Reedy  added the comment:

To review: Serhiy reported 3 'IDLE' bugs: tripled DeprecationWarning (now 
joined by SyntaxWarning), printing to console (if available) instead of Shell, 
and an exit exception.

1. Codeop generates the tripicates; #40807 will fix that.
2. PR-15311 prints warnings to Shell, but I held off  pending some fix.  3. The 
exception (a duplicate report) was fixed on #35623.
4. PR-15500 stopped turning a SyntaxWarning into a SyntaxError.

Additional issues, semi-independent.
5. REPL prints warning after code, IDLE before
6. REPL prints 1 line, IDLE 4, but this is related to Shell warnings going to 
the console.  IDLE should use 1 and highlight.
7. Should IDLE extend scope of deduplication?  Yes with 4 lines, maybe not with 
1 line.
8. REPL partially deduplicates within compound statement; see #40807.

[issue40805] Can no longer patch flask.g

[Terry J. Reedy]

Terry J. Reedy  added the comment:

Sorry, but I believe you were misdirected*.  mock, as opposed to unittest.mock, 
pytest, flask, and werkzeug  are 3rd party modules.  The error report seems to 
be missing part of the stacktrace at both ends.  What line is your file 
resulted in the error?  (This time we can guess == @patch. @What called 
_lookup_app_object in flask?  (I have no idea.)

However, once contextlib._GeneratorContextManager calls next(self.gen), the 
rest of the trace is outside the stdlib.  At the end, the RuntimeError is 
raised by flask, not by python, because the flask _app_ctx_stack.top does not 
exist.  If you do not understand their error message, ask flask people.

* I assume that cjw296 *glanced* at your report, saw 'RuntimeError', and too 
quickly assumed 'cpython error'.  flask could have defined, for instance, 
FlaskRuntimeError for its error reporting.

[issue35621] asyncio.create_subprocess_exec() only works with main event loop

[Kyle Stanley]

Kyle Stanley  added the comment:

> is there a workaround for earlier Python versions that does not involve 
> patching the standard library?

You could potentially try using the new default watcher, 
`ThreadedChildWatcher`, by implementing it locally and setting it as the child 
watcher to use (instead of `SafeChildWatcher`) with `set_child_watcher()`. 
AFAICT, the current implementation should work well for earlier versions of 
Python that don't have it, we just can't include it earlier than 3.8 since it's 
a new feature.

See 
https://github.com/python/cpython/blob/4649202ea75d48e1496e99911709824ca2d3170e/Lib/asyncio/unix_events.py#L1326

[issue40762] Writing bytes using CSV module results in b prefixed strings

[Terry J. Reedy]

Terry J. Reedy  added the comment:

I make 5 core developers who agree that csv should definitely *not* assume that 
bytes given to it represent encoded text, reverting to the confusion of Python 
1 and 2.  (And even it if did, it should not assume that the encoding of the 
given to it and the encoding of the file are the same, or even that all bytes 
given to it have the same encoding!)

If a user does not like the current default wonky mixed ascii-hex string 
representation of bytes, the user should explicitly convert bytes to the 
representation they want.  Here are just 3 examples, 2 with possible variations.

>>> b'\xc2a9'.hex()  # One might want to add prefix '0x' or r'\x'.
'c26139' # Or add a separator.
>>> str(list(b'\xc2a9'))  # One might want to change or strip brackets, 
'[194, 97, 57]'   # change separator, or strip spaces.
>>> b'\xc2a9'.decode('latin-1')
'Âa9'

What is best depends on the expected reader of the output.  Pandas users who 
don't like Pandas' csv output should talk to its authors.  They are welcome to 
ask advice on python-list.

Eric: I agree that adding 'strict=False' might be a good idea (in a new issue).

Please keep this on python-list.

How you download files depends on what/where they are. Some are 
downloaded via a browser (probably how you got Anaconda); some via FTP; 
if you're using version control software such as Git (GitHub), via that; 
if you're talking about Python modules and extensions on PyPI, via pip.

That program is an installer for Python. It's only purpose is to
install
or uninstall Python, and nothing else. It's not for downloading
other files.

[issue40754] Test installers before releasing (ModuleNotFoundErrors)

[Ned Deily]

Ned Deily  added the comment:

> So it seems that only Linux has "installed" builbot tests. I suppose the next 
> step is adding some macOS and Windows ones.

Having more buildbots test from "installed" locations, rather than the build 
directory, is good.

But that's not the whole issue here. Those "installed" tests are only testing 
that a Python runs from an installed location on the same system it was built.  
The Windows and macOS installers use various packaging methods to provide 
complete Python installations, including binaries, that can be installed on 
other systems using various OS-native install methods familiar to users of each 
platform. And the binaries are generally built in such a way to support running 
on multiple release versions of its operating system. For example, the current 
Python installers for macOS from python.org are usable on macOS 10.9 through 
10.15. To produce the various installer packages, there are other layers of 
tooling involved, say, on top of "make install" in the Unixy build process for 
macOS; something similar is true for Windows releases.

FWIW, every macOS installer is test installed on a vanilla system, the whole 
standard test suite is run, and an IDLE smoke test is run to ensure there are 
no noticeable regressions before handing the build artifacts off to the release 
manager. Every installer is tested on at least one supported macOS version and 
usually more than one.

[issue40754] Test installers before releasing (ModuleNotFoundErrors)

[Pablo Galindo Salgado]

Pablo Galindo Salgado  added the comment:

We have a bunch of buildbots that test the installed Python. For instance, if 
you search for "installed" in 
https://buildbot.python.org/all/#/builders?tags=%2B3.x we have:

aarch64 Fedora Rawhide Clang Installed 3.x  
aarch64 Fedora Stable Clang Installed 3.x   
AMD64 Fedora Rawhide Clang Installed 3.x
AMD64 Fedora Stable Clang Installed 3.x
PPC64LE Fedora Rawhide Clang Installed 3.x
PPC64LE Fedora Stable Clang Installed 3.x
s390x Fedora Clang Installed 3.x
s390x Fedora Rawhide Clang Installed 3.x
x86 Gentoo Installed with X

So it seems that only Linux has "installed" builbot tests. I suppose the next 
step is adding some macOS and Windows ones.

[issue40754] Test installers before releasing (ModuleNotFoundErrors)

[Terry J. Reedy]

Terry J. Reedy  added the comment:

I verified that running tests for installed 64-bit 3.9.0b1 on Win10 is somewhat 
a joke.  I got 22 failures.  Multiple tests failed on missing 
_testinternalcapi, and at least 1 on _xxtestfuzz.  Several tests had multiple 
failures and would need to be run individually and verbosely to see why.  For 
instance, test_itertools tries to run test.support.__init__.checksizeof 4 
times, and the latter imports _testinternalcapi, resulting is 4 failures.

Release managers: I think installers should be run and the suite run with the 
result.  This is not the first time a file has been omitted.  One needed by 
IDLE was once omitted, I believe on Windows.  There is now a test that reads 
it, but is useless unless run.  (And I should add checks for all the other 'not 
.py' files.)

honglei: Thank you for both posts.  Next time, please remove the quoted message 
when replying by email.  Once posted on the web page, below the quoted message, 
the quote becomes redundant noise.

[issue20353] Hanging bug with multiprocessing + sqlite3 + tkinter (OS X 10.9 only)

[Terry J. Reedy]

Terry J. Reedy  added the comment:

hang.py uses the default multiprocessing start method, which was then 'fork'.  
It is now 'spawn' on macOS.  And there have been many other changes.  When I 
run the following from IDLE, it finishes immediately.

import multiprocessing, sqlite3
def hang():
   sqlite3.connect('/tmp/foo')
if __name__ == '__main__':
   multiprocessing.Pool(2).apply_async(hang, []).get(999)
print('done')

Unless I am missing something, this should be closed as 'out of date'.

[issue40819] IDLE: Test right-click and context menu tests

[Terry J. Reedy]

Terry J. Reedy  added the comment:

Thanks for the report. I verified the context menu defect on Windows and Mac 
Mohave.  The menu and shortcuts still work on both.

This regression was introduced by the first PR for #39885.  I mistakenly 
delayed the fixer, PR-18951, to finish new tests. (On current Win10, disabled 
items are nearly black dark gray that I easily confuse with enabled black.  On 
Mac, the contrast between its light-medium gray and black is unmistakable.)

I polished the fixer and merged it, with only manual testing, to immediately 
fix the regression.  I re-labelled this issue to add an automated test that 
would have caught it.

Re: Ram memory not freed after executing python script on ubuntu system (rmlibre)

That depends on what "much" means.

Glibc does return blocks to the OS which it allocated via mmap, By
default, these are allocations larger than 128 kB.

So that means that

* Blocks smaller than 512 bytes are returned to the OS if the arena they
  are in is completely empty.

* Blocks between 512 bytes and 128 kB are not returned to the OS (unless
  they happen to be at the end of the heap).

* Blocks larger than 128 kB are returned to the OS:

Most Python objects are probably smaller than 512 bytes, so whether
"much" is returned to the OS mostly depends on whether arenas ever get
completely empty.

This stupid little test program returns memory to the OS quite nicely,
because it allocates and frees lots of objects together:

---8<--8<--8<--8<--8<--8<--8<--8<---
#!/usr/bin/python3
import time

a = []
for i in range(10):
print('a', i)
x = []
for j in range(100):
x.append(j)
a.append(x)
time.sleep(1)
if i >= 5:
print('d', i - 5)
a[i - 5] = None
time.sleep(1)
print('f')
---8<--8<--8<--8<--8<--8<--8<--8<---

(run it with strace to watch the mmap/munmap system calls)

A program with more random allocation patterns may suffer severe
internal fragmentation and end up with many mostly empty arenas.

> You can try jemalloc instead of glibc.

I think that would only make a difference if you have lots of objects
between 512 B and 128 kB. And only if those of similar size are
allocated and freed together.

Well, yes. But "Neither the PSF nor the Python core developers" is quite
different from "Nobody ever".

That's like saying "Nobody has ever been on the moon" is true if you
replace "Nobody" with "No catholic bishop".

[issue40821] os.getlogin() not working

[Manickaraja Kumarappan]

New submission from Manickaraja Kumarappan :

Hi,
We are using below command to get the original login user. In some cases folks 
sudo as different user and run commands. In some cases folks use switch to 
different user (su - <>) and then run command. In all cases we would like to 
get original user who logged into the terminal to run the command. We are using 
below command to get the same.

user=os.getlogin()

We got three RHEL linux systems with Python 3 and strangely on two of them this 
command works fine. However only on third system it is failing with below error

OSError: [Errno 6] No such device or address

Not sure if it is some o/s env setup which is causing this command to fail. Any 
pointers to run this command will be of great help so that we can pin point the 
issue.

Please note on faiing system if I do python and then run the command it works 
fine without any issue. However if it is triggered through our Scheduler 
(Control M) it is failing with above message.

Give below is the command how Scheduler triggers the job.

/bin/su - edwadm -c /bin/sh -x <>

Thanks
Manick.

I got a bit side-tracked in my previous reply, so I'm trying to stick to my
original point more closely this time.

Your claim was that "nobody ever requires you to comply with [PEP 8] for
any other code".

For this claim to be false, only one person/company/project needs to
require somebody to comply with PEP 8. Their motives are completely
irrelevant. They may believe that compliance with PEP 8 is necessary
for any Python code. They may just think that PEP 8 is a good idea. They
may have had a vision of Elvis singing the text of PEP 8 to the tune of
Jailhouse Rock. It doesn't matter. Your claim was about their actions,
not their motives.

The OP seems to feel that he is required by his colleagues to comply
with PEP 8. So his company would serve as a counter-example (though
maybe a weak one, since it doesn't seem to be a hard requirement).

hp

PS: We have "PEP 8, unless you have a good reason to deviate" in our
style guide, but we don't enforce that at all (unfortunately).

This is a strange usage of the term "hardcoded", Normally, hardcoded

You would have to use a different class for that. I don't know one
offhand which implements the behaviour you want, but for example
TimedRotatingFileHandler switches log files after a configurable
interval. So for example

class=TimedRotatingFileHandler
when=H

would start a new log every hour (and rename the old log to contain a
timestamp).

You may need to write a handler which implements the behaviour you want.
Or maybe there is one on PyPi.

https://bugs.python.org/issue21269).

However, the change did not add a change version to the documentation.

The ``Doc/library/unittest.mock.rst`` file should include the following in the 
``Call`` section:
```
The ``Doc/library/unittest.mock.rst`` file should include the following in the

Format Logfile Name with logging.ini

[connor . r . novak]

In an effort to clean up my python logging practices when creating libraries, I 
have begun reading into "Advanced Logging" and converting my logging practices 
into logging configuration `.ini` files:

[link](https://docs.python.org/3.4/howto/logging.html#configuring-logging)

My question is: When defining a FileHandler in a `.ini` file, all of the 
examples that I've seen hardcode the name and location of the log file. In the 
code snippet below, `python.log` is hardcoded into the `.ini` file:

```
[handler_hand02]
class=FileHandler
level=DEBUG
formatter=form02
args=('python.log', 'w')
```
[code reference 
link](https://docs.python.org/3.4/library/logging.config.html#logging-config-fileformat)

Desired Behavior:
On each run of the program, a new logfile is created in the `logs/` directory 
named "_program.log".

Current Behavior: 
The format in the example above overwrites a single file called "python.log" on 
each run, which is not the desired behavior.

Question: Is there a standard procedure for using .ini files to create a new 
logfile prepended with the current Unix timestamp on each run of the program?

[Souvik Dutta]

Do you have DirectX installed. It must solve the problem.

[issue40819] Idle Context Menu Copy/Cut Grayed Out

[Bev]

New submission from Bev :

In Idle on macOS, when I select text in either the Shell or a file, both copy 
and cut should be available in the context menu, but they are grayed out (not 
selectable).  Both copy and cut are still available via the menu bar Edit menu 
and keyboard shortcuts, c and x, respectively.  I tried this 
on macOS El Capitan 10.11.6 and Catalina 10.15.4

Re: Custom logging function

[zljubisic]

Hi Peter.
Finally I got it. :)

That's it. It works. Thanks.

So, in each class, I will in init method execute:
self.logger = logging.getLogger()

and than everywhere use self.logger.debug('...') in order to produce the 
message.

Best regards.

[issue40817] Document the asyncio shell

[Rémi Lapeyre]

New submission from Rémi Lapeyre :

Python 3.8 introduced `python -m asyncio` to run a Python shell with asyncio 
support. It had a note in What's New but was not documented, I think a note in 
https://docs.python.org/3/library/asyncio.html should be helpful.


This could be a good issue for a new contributor.

Thank you for responding! The computers showing the problem are remote to me

[issue40734] /usr/bin surprisingly in sys.path under IDLE

[E. Paine]

E. Paine  added the comment:

This is simply because the Python interpreter is running from /usr/bin. This is 
shown if you call:

cp /usr/bin/idle idle
./idle

In this case, the Python interpreter is running from the directory you are in 
and /usr/bin shouldn't(!) show in the path (at least on my system...)

As others have pointed out, it's a problem of how many versions to
build.  By the time 3.N is at the stage of receiving security-only,
patch-only types of releases, both 3.N+1 and 3.N+2 are being actively
built and supported, including Windows installers, both later releases
will will include those fixes (assuming they're necessary), so you have
plenty to choose from.  You have the option of picking the patches and
building your own if something _requires_ you to stay on 3.N, though
admittedly that is less easy.  It seems to be a reasonable compromise to
me, but that's from the point of view of a kibitzer!

EuroPython 2020: Schedule published

[M.-A. Lemburg]

We are very excited to announce the first version of our EuroPython
2020 schedule:

 * EuroPython 2020 Schedule *

https://ep2020.europython.eu/schedule/


More sessions than we ever dreamed of
-

After the 2nd CFP, we found that we had so many good talk submissions
that we were able to open a fourth track. Together with the newly
added slots for the Indian / Asian / Pacific and Americas time zones,
we now have a fully packed program, with:

- more than 110 sessions
- more than 110 speakers from around the world
- 4 brilliant keynotes, two of which are already published
- 2 exciting lightning talk blocks
- 4 all-day tracks, with a whole track dedicated to data science topics
- a poster track, which we’ll announce next week
- a virtual social event
- an after party
- and lots of socializing on our conference platform

We are proud to have reached almost the size of our in-person event
with the online version of EuroPython 2020.


Never miss a talk
-

All talks will be made available to the attendees as live Webinars,
with easy switching between tracks, as well as online streams, which
will allow rewinding to watch talks you may have missed during the
day.


Conference Tickets
--

Conference tickets are available on our registration page. We have
simplified and greatly reduced the prices for the EuroPython 2020
online edition:

https://ep2020.europython.eu/registration/buy-tickets/

As always, all proceeds from the conference will go into our grants
budget, which we use to fund financial aid for the next EuroPython
edition, special workshops and other European conferences and
projects:

* EuroPython Society Grants Program *

  https://www.europython-society.org/grants

We hope to see lots of you at the conference in July. Rest assured
that we’ll make this a great event again — even within the limitations
of running the conference online.


Sprints
---

On Saturday and Sunday, we will have sprints/hackathons on a variety
of topics. Registration of sprint topics has already started. If you
would like to run a sprint, please add your sprint topic to the wiki
page we have available for this:


 * EuroPython 2020 Sprints Listing *

 https://wiki.python.org/moin/EuroPython2020/Sprints


If registrations continue as they currently do, we will have a few
hundred people waiting to participate in your sprint projects, so this
is the perfect chance for you to promote your project and find new
contributors.

Participation in the sprints is free, but does require
registration. We will provide the necessary collaboration tools in
form of dedicated Jitsi or Zoom virtual rooms and text channels on our
Discord server.


EuroPython is your conference
-

EuroPython has always been a completely volunteer based effort. The
organizers work hundreds of hours to make the event happen and will
try very hard to create an inspiring and exciting event.

However, we can only provide the setting. You, as our attendees, are
the ones who fill it with life and creativity.

We are very much looking forward to having you at the conference !

but not when running `python3 main.py`:

The Multiprocessing docs specifically say that Queue is process- and thread-

https://docs.python.org/3/library/multiprocessing.html#exchanging-objects-between-processes.

But this information is not given for the various synchronisation primitives 
and such (Lock, Semaphore, Event, etc)

Are they thread-safe?  Should the docs say whether they are or are not?
