[issue41446] New demo, using a web api

[Mariatta]

Mariatta  added the comment:

Thanks for your interest in adding this to CPython but I think this demo does 
not belong in CPython repository. Perhaps it should be written as a demo for 
helioviewer API and be part of helioviewer documentation. We already have a 
documentation for urllib for how to make API calls.

Step 1 is to copy this sideways: keep the existing setup, but do the dev 
in a separate directory. The Mykefile in my personal dev directory has a 
"_home" target which installed the current state of play into my home 
directory.

Once you have that, it is easy to make more clones to pursue things 
separately.

To that last part, I have a personal script "env-dev" (aliased as just 
"dev"), here:

https://hg.sr.ht/~cameron-simpson/css/browse/bin/env-dev?rev=tip

Feel free to copy it.

Its purpose is to run the code from the current directory by prefixing 
various path environment variables, etc. Additionally it sources the 
file ".env.sh" in the current directory or ancestor for customisation 
beyond what it does automatically. It also utilises the venv if present.

So to run the test code I go:

$ dev the-programme ...

and it uses the scripts and modules in my development directory.

The nice thing about a virtualenv is that you can run specific Python 
versions with specific modules installed. It is easy to keep a few 
around.

You utilise the virtualenv by invoking via the "python" executable 
within the virtualenv. That hooks up the virtualenv for the run. (Ignore 
"activate", it is a confusing source of pain IMO.)

Moving to "production" is just a matter of maintaining a production 
virtualenv, using the python and modules you see fit for production.

For example, I keep a virtualenv in the "venv" subdirectory of the 
development tree. I keep a personal, "production", virtualenv in 
~/var/venv/3, and ~/var/venv/3/bin is towards the front of my $PATH.

Typically you keep a "requirements.txt" file in your dev tree which 
specifies the modules you want. The filename is just a convention. The 
to update production you'd just go:

~/var/venv/3/bin/pip install -U -r requirements.txt

where "~/var/venv/3/bin/pip" is _my_ production venv - adjust for your 
own, and "requirements.txt" is the reference file you want to use.

>There's also the issue that I'm moving code from Python 2 to Python 3
>so which virtual environment should I use?

Make one of each - that way it is easy to run your tests against either 
or both at once. So maybe (in your dev tree) make a "venv2" with a 
Python 2 virtualenv and a "venv3" with a Python 3 one, then you can run 
python out of each as required.

Also, keep a make target to build the virtualenvs. Here's mine, which 
just does one based on "python3".

dev = env-dev -d $. -x
base_python = python3
venv_dir = $./venv
venv_requirements = $./venv-requirements.txt
venv_pip = $(venv_python) -m pip
venv_python = $(venv_dir)/bin/python

_venv:
@[ -d '$(venv_dir)/' ] || set-x mkdir '$(venv_dir)'
[ -x '$(venv_python)' ] || { \
  set -xue \
  rm -rf '$(venv_dir)' \
  $(base_python) -m venv '$(venv_dir)' \
}
$(dev) $(venv_pip) install -U wheel pip
$(dev) $(venv_pip) install -U -r $(venv_requirements)

Doing some searching - - - - sub-class really doesn't have a lot of 'official'
info. Perhaps an information source might be pointed out?


You're further along that path than I!

Sometimes the authors maintain an helpful web site/page, but I don't know.


...


Reading through more docs there is a possibility of using the 'format'
command. Would need to first come up with a way of describing the
months (with their attendant week numbers) and then describe a
formating system which would then enable a use of 'print' to achieve
the desired goal.

Is this perhaps a good way of doing this?


Outlined earlier.


Question: what is the specification for 'first month' and 'last month' 
in the calendar?


i) year-based: eg from 2020-2023, represents 48 months starting from Jan 
2020 and continuing until Dec 2023 (inclusive).


ii) month-based: there is no need to 'start' with January, or to finish 
in December, eg 2020-08 -> 2023-07


iii) week-based: (included because of evident import in your thinking), 
eg 2020-W26 -> 2023W25

- watch out for leap years!

The last introduces the (very inconvenient) possibility of the first or 
last month being an incomplete 4~6 week 'block' and thus perhaps 
doubling the complexity of the "merge". However, it may be more 
convenient to translate weekNR into monthNR (and thus, name) than the 
reverse.

(that's a question? not statement!)

It is very disappointing - - - -suggests that thinking outside the space of
one year is somehow deprecated. Frustrated when what you do demands
that you think in longer periods of time (and yet have to function within
the week as well).


I agree - says he who tactically changes his 'events calendar' every 
half-year, to ensure that there is more than a six-month planning 
horizon. Sister-in-Law has just this morning blocked-out dates for 
family gatherings ("you are expected to attend!") for not just 
Christmas/December, but into Jan, Feb, and Easter holidays (Uni 
vacation) next year; because U.David is but a mere-male and needs lots 
of 'extra help'...

(and because she knows 'the system', and has something similar at home!)



There are other helper functions. Also, we are invited to sub-class.


Hmm - - - will have to investigate that.


I'm thinking that the month function/method might be a better way to go 
(than year-at-a-time).


For visualisation (per next para), have you tried computing a month in 
the REPL and then str.split()-ting the output into separate week-strings?




Might it be possible to generate multiple year (or month) groups, split
them by line, and then reassemble line-by-line to produce the width and
temporal length required?


Likely work well if the months were considered as discrete blocks.
Thinking that one could have something like

January 20xx  February 20xx
   Su  Mo  Tu  We  Th  Fr  Sa Su  Mo  Tu  We  Th  Fr  Sa
1  1 2 3455
  12
2 6 78 910  11  12   6 3 45 6
7   89
313   14  15   16   17  18  19   710   11  12   13   14  15  16
420   21  22   23   24  25  26   8
527   28  29   30   31

It is very useful for me to have the week numbers included. Have
learned some fascinating things (some months have 6 weeks in
them!) and the joys of formating (grin!).


What do you think?


I'm no expert with the calendar module, having used it as many times as 
(probably only) once before!


However, skim-reading that page of the docs, I'd say that using the 
class to do the formatting is better than 'reinventing the wheel', and 
thus the question becomes: could the 'standard output' be post-processed 
into the form required?


The outline above (ignoring month/year and day headings) is basically:

weekNR  gap weekNR month> ...


as far across the page/screen as there is space/per the requirements.

Given that a  seems to be a fixed-length string, then 
you could indeed employ format() or f-strings with formatting.


The fact that some months have fewer, or more, weeks to include, is 
largely irrelevant. The solution is a standard "merge" algorithm. (us 
'silver surfers' cut our teeth on sorting, searching, and merging as the 
three pillars of "batch processing").


To print across the page/screen, we divide the available number of 
character-columns by the number of columns a single month's data 
requires (plus inter-month spacing) and this gives the maximum number of 
months the can be displayed 'across'.


Dividing that number into the number of months within the period, will 
give the number of month-rows required to 'do the job'.


A month-row could be defined as: 'as many lines as it takes to display 
every week of the month' (plus vertical separation/spacing).


So, now the challenge is to print each output line, combining 
(laterally) all of the relevant data/dates, in such a manner that after 
every so-many output lines, the visual-blocks representing each 
individual month's dates will become apparent.


The "merge" for line n (n:1-4~6) means to take the n-th  
from each month in the current month-row and format them into a single 
o/p line. If a month does not have an n-th week, then substitute the 
requisite number of spaces (unless handled by f-string/format() 
"width"). Print the o/p line...

(yes, I omitted the weekNR-s, but adding them is trivial)



I was starting from what I understood (how to print 'a' year) working
to get closer to what I could use. Ncal allows me to display a
calendar except I'm restricted to a display only 3 months wide. More
than one month is relatively easy to display from present but not
from some other point. It would seem that the 80 column display
still rules supreme - - - - - and that's on a 1920 pixel wide monitor.


It may be possible by sub-classing, to override

The actual crash happened inside this module. I'm guessing that's some

This question seems a little vague. How are you creating this "calendar
function"? Are you using the Python Standard Library calendar, or
perhaps talking about datetime calculations?

Please copy-paste code showing this "lock".


Maybe its not a lock - - - - but there seems to be no way to display a 
calendar starting

from a date that is 3 years in time frame.

...


I would like to show something like 2024 through the end of 2028.



Let's start with the disappointing information:-
- please read https://docs.python.org/3/library/calendar.html and the 
*function's* help:


>>> help(cal.calendar)
Help on method formatyear in module calendar:
formatyear(theyear, w=2, l=1, c=6, m=3) method of calendar.TextCalendar 
instance

Returns a year's calendar as a multi-line string.

The word "year" is singular, and the parameters are all to do with the 
output-presentation. We can't even request 'the rest of the year from 
August onwards'!


There are other helper functions. Also, we are invited to sub-class.

Might it be possible to generate multiple year (or month) groups, split 
them by line, and then reassemble line-by-line to produce the width and 
temporal length required?


What do you think?

Yes to this advice.

And I am also an editor in one window and command line in another window 
person.

Note that a Mercurial "named branch" is a more, um, "solid" thing than a 
git branch, which is much more like a mercurial bookmark. Basicly, you 
can't easily remove a mercurial named branch. Bookmarks you can make and 
discard freely. That said, I hardly ever use bookmarks.

You also do not need a named branch - a cloned directory works as well.

I use mercurial branches for long lived things, particularly development 
on theme. My personal library has a bunch of long term branches - they 
all get merged back into "default" frequently as things stabilise.

So for your scenario I'd add a named branch for the development, 
particularly if it has a theme. But also as Marco suggests, clone your 
tree into another directory for the development.

Look:

[~]fleet2*> cd ~/hg
/Users/cameron/hg
[~/hg]fleet2*> ls -d css-*
css-adzapper css-nodedb-nested-curly-syntax
css-aws  css-nodedb-proxyobjs
css-beyonwiz css-persist
css-calibre  css-pilfer
css-contractutilscss-pt
css-csbugcss-py3
[...]

Each of those trees is a clone of the main "css" tree. They do not all 
have named branches.

[~/hg]fleet2*> cd css
[~/hg/css(hg:default)]fleet2*> hg clone . ../css-newdev
[~/hg/css(hg:default)]fleet2*> cd ../css-newdev
[~/hg/css-newdev(hg:default)]fleet2*> hg branch newdev
[~/hg/css-newdev(hg:newdev)]fleet2*>

So now I've got a clone in css-newdev, for a new named branch "newdev" 
(obviously pick a better branch name). No need to make a named branch, 
unless this is long lived, in which case it helps you track where 
changes occurred - the branch name is recorded in commits.

You can merge to or from "../css" as needed.

I find this _much_ easier to deal with than the common git habit of 
switching branches in place (which you can also do).

Cheers,
Cameron Simpson

[issue41451] Cannot subclass typing.Generic with __weakref__ slot in Python 3.6

[Ned Deily]

Ned Deily  added the comment:

Thank you for the report and for the analysis. As you probably know, Python 3.6 
is now in the security phase of its life cycle so generally only fixes for 
security-related issues are provided at this point. This issue doesn't seem to 
fall into that category. If you have a workaround for 3.6.x, documenting it is 
probably the best available option. I'm going to close this as "wont fix".

Pythran 0.9.6 - talar tro

[Serge Guelton]

Hi folks, and sorry for the double posting if any,

It's my pleasure to share with you the 0.9.6 release of Pythran, code-named
talar-tro [0].

Pythran is a compiler for numerical kernels written in Python.
It doesn't require much type information and its inputs are 100% compatible with
the Python interpreter (but the other way around is not true!)

More than 6 months have passed since last revision, so the changelog is a bit
dense [1], but basically, that's the first release that only supports Python3 
[2],
I made quite a lot of changes in the expression engine and it comes with more
supported numpy stuff, hopefully less bugs etc.

As usual, it's available on Pypi, conda-forge and github :-)

[1] https://pythran.readthedocs.io/en/latest/Changelog.html

[issue41421] Random.paretovariate sometimes raises ZeroDivisionError for small alpha

[Tim Peters]

Tim Peters  added the comment:

That text is fine, if you feel something needs to be said at all. I really 
don't. A Pareto distribution of this kind with parameter <= 1.0 has infinite 
expected value - VERY long tail. Anyone who knows what they're doing already 
knows that. The reason the implementation can't "blow up" for parameters >= 
(roughly) 0.1 isn't that IEEE doubles have such a large dynamic range but 
rather that they can't represent a number < 1.0 larger than 1 - 2**-53 (so u = 
1 - random.random() is always at least 2**-53). The actual distribution has 
infinite expected value nonetheless, but the implementation is incapable of 
generating any of its very large values (which, while very rare, are also very 
large).

[issue41075] IDLE: Better support history navigation

[Terry J. Reedy]

Terry J. Reedy  added the comment:

History and up/down is apart of #2704.  It has patches that include the up/down 
change, but I don't expect to use any of them as they are.

I tried Shift/Control/Alt - Up/Down and none worked.  Rebinding just Up/Down 
did (in Shell only, leaving up/down unchanged in Editor).  But not having 
up/down work to move between lines in the Shell multiline statement entry area 
is not acceptable to me.  I don't know if modifiers can never work with up/down 
or if there is something that would make it work.

[issue2704] IDLE: Patch to make PyShell behave more like a Terminal interface

[Terry J. Reedy]

Terry J. Reedy  added the comment:

#41075 is specifically about history navigation.  I tried Shift/Control/Alt - 
Up/Down and none worked.  Rebinding just Up/Down did (in Shell, with Editor 
unchanged).  But not having up/down work to move between lines in the Shell 
multiline statement entry area is not acceptable to me.  Two additional idea 
from the new issue: a) Add history commands to context menu to make them more 
discoverable; b) When statement has SyntaxError, put Error message in box and 
let user edit bad code directly, as in Editor.

[issue41421] Random.paretovariate sometimes raises ZeroDivisionError for small alpha

[Raymond Hettinger]

Raymond Hettinger  added the comment:

How about this wording?

If alpha is smaller than 0.1, an occasional OverflowError can
arise when the variate exceeds the range of Python float.

I like using 0.1 because it's easy and gives us some wiggle room.  The actual 
cutoff is lower:

>>> alpha = 0.05079
>>> sys.float_info.epsilon ** (-1.0 / alpha)

>>> alpha = 0.05078
>>> sys.float_info.epsilon ** (-1.0 / alpha)

[issue41455] Python Devguide differs from python docs

[Yaroslac]

New submission from Yaroslac :

As I can see here 
https://github.com/python/devguide/blob/master/garbage_collector.rst#collecting-the-oldest-generation

> the GC only triggers a full collection of the oldest generation if the ratio 
> long_lived_pending / long_lived_total is above a given value (hardwired to

But in the python docs here 
https://docs.python.org/3.10/library/gc.html#gc.set_threshold

> When the number of allocations minus the number of deallocations exceeds 
> threshold0, collection starts. Initially only generation 0 is examined. If

(Its an even bigger mess now when its truncated to 80 columns. Can't change
the mess but I can tell you that it doesn't 'look that way'! Don't know how to
include an example in the body and have it be even a bit accurate - - - please
advise if there is a way.)

  File "", line 1, in 
NameError: name 'cd' is not defined

so 'cd' seems to be a problem.

Tried changing 'cd' to calendar and that gives the desired response.

Except its a neat 3 months wide very very very many rows of calendar.

I'm trying to figure out how to do something like this:

The formatting here is a mess.
The months are centered. The week numbers are consecutive from the
starting date.
The dates are centered under the weekday name. If you've ever used
ncal its like that except
that I can now have up to 7 months wide if the terminal is wide enough
(>180 columns IIRC).
A mentor was working on this in Perl but as he died some couple months
ago its up to me
to make what I want.
Because it seems like there are a lot of disparate things happening
its not very straight
forward trying to replicate and extend my friend's efforts except in
Python. (My friend
preferred to work in Perl rather than Python and I'm wanting to learn
Python. I understand
that this is not perhaps the easiest way to learn something but it
sure is interesting!)

[issue41454] while loop bug on list

[Dexter Ramos]

Dexter Ramos  added the comment:

Thank you Mr. Erick Smith. Now I know. I also tried to find the hard way like 
this:

finding nemo-
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 1, 2, 3, 4] --->index
[4, 1, 2, 5, 7, 4, 2, 8, 9, 5, 3, 2, 4, 6] --->original list
 / --->started at index 0 with value of 
4
[1, 2, 5, 7, 2, 8, 9, 5, 3, 2, 6, 4] --->1st iteration, all 4's are removed 
then appended so the index adjusted
/--->next at index 1 with a value of 2 
(whereas value 1 was skipped which had index 1 originally; this is not seen on 
the output because it has no duplicate)
[1, 5, 7, 8, 9, 5, 3, 6, 4, 2] --->3rd iteration
   / --->next at index 2 with value of 7; value 
5 was skipped which had the index 2 originally; cause found!
[1, 5, 8, 9, 5, 3, 6, 4, 2, 7] --->4th ...
...
---nemo found---
Credits to you.

Here is the new working code:
---code
bunchofnumbers = [4, 1, 2, 5, 7, 4, 2, 8, 9, 5, 3, 2, 4, 6]
for eachnumber in bunchofnumbers.copy():
while eachnumber in bunchofnumbers:
bunchofnumbers.remove(eachnumber)
bunchofnumbers.append(eachnumber)
bunchofnumbers.sort()
---end of code-
OUTPUT:
[1, 2, 3, 4, 5, 6, 7, 8, 9]
print(bunchofnumbers)

[issue41454] while loop bug on list

[Eric V. Smith]

Eric V. Smith  added the comment:

You're mutating the list while iterating over it, which is causing the behavior 
you're seeing. This isn't a bug.

See for example 
https://stackoverflow.com/questions/6260089/strange-result-when-removing-item-from-a-list

Also, when reporting bugs in the future, please include the output you got, and 
how it differs from what you expected. It's difficult to guess.

[issue41451] Cannot subclass typing.Generic with __weakref__ slot in Python 3.6

[Joshua Bronson]

Joshua Bronson  added the comment:

Thanks so much, @oremanj! Indeed, merely subscripting the class triggers the 
bug, and your 'del slots' workaround does the trick!

For completeness, there is an updated (yet more minimal) repro below/attached.


"""Repro for Python 3.6 slots + weakref + typing.Generic subclass bug."""

from typing import Generic, TypeVar
from weakref import ref


T = TypeVar("T")

class MyGeneric(Generic[T]):
"""MyGeneric works as expected.

>>> example = MyGeneric()
>>> example
<__main__.MyGeneric object at ...>
>>> example._other
<__main__.MyGeneric object at ...>
>>> example._other._other

>>> from pickle import dumps, loads
>>> pickled = dumps(example)
>>> roundtripped = loads(pickled)
>>> roundtripped
<__main__.MyGeneric object at ...>

"""

__slots__ = ("_other", "__weakref__")

def __init__(self) -> None:
self._init_other()

def _init_other(self) -> None:
other = self.__class__.__new__(self.__class__)
other._other = ref(self)
self._other = other

def __getstate__(self) -> dict:
"""Needed to enable pickling due to use of __slots__ and weakrefs."""
return {}

def __setstate__(self, _) -> None:
"""Needed because use of __slots__ would prevent unpickling 
otherwise."""
self._init_other()


# Merely the following is enough to trigger the bug on Python 3.6:
MyGeneric[T]

# This works around the issue if run first (thanks @oremanj):
del MyGeneric.__slots__  # does not actually 'unslot' the class

[issue41454] while loop bug on list

[Dexter Ramos]

New submission from Dexter Ramos :

The output should have no duplicates but it has. When I added another "5" on 
the list it goes okay and is still okay if I add more. But when there is only 
two 5's it won't do its job.

Pygobject style question

[Chris Green]

Having (after lots of help from here, thank you) finally converted my
Python 2, gtk 2 program to Python 3 and pygobject gtk 3 I'm left with
a couple of what might be called style questions.

I guess it's mostly down to what feels right to me but there may be
good reasons for choosing one way over another and, if so, I'd like to
know what they are.

So, my original code had:-

...
...
self.buffer = gtk.TextBuffer()
self.view = gtk.TextView(self.buffer)
...
...


This doesn't work in gtk+ 3 (or at least I don't think it does, the
converter script changed it) and there seem to be several ways of
doing it now:-

...
...
self.buffer = Gtk.TextBuffer()
self.view = Gtk.TextView(buffer = self.buffer)
...
...


...
...
self.buffer = Gtk.TextBuffer()
self.view = Gtk.TextView.new_with_buffer(self.buffer)
...
...


...
...
self.view = Gtk.TextView()
self.buffer = self.view.get_buffer()
...
...


...
...
self.view = Gtk.TextView()
self.buffer = Gtk.TextBuffer()
self.view.set_buffer(self.buffer)
...
...

Is there any reason to prefer any one of the above over the others?

Obviously the last one is a line more but lends itself to using
several Gtk.TextBuffer objects in on Gtk.TextView.

[issue29269] test_socket failing in solaris

[Dennis Clarke]

Dennis Clarke  added the comment:

Well here we are in 2020 and Solaris systems are still running just fine. In 
fact, some big Fujitsu SPARC systems are running in production for years and 
years and also, no surprise, this test still fails horrifically on old stable 
Solaris 10. Python is turning into a piece of supposedly open source software 
with many commercial interests with their hands inside of it. I am not sure how 
to get this bug fixed but I can certainly report that it is still broken in 
3.7.8 on a very stable and reliable platform.

Maybe its not a lock - - - - but there seems to be no way to display a
calendar starting
from a date that is 3 years in time frame.

Re: questions re: calendar module

I regularly work in planning through multiple years at once.
This means that I like to have a lot of stuff available in a calendar
function.
Python seems to be locked when I need to display more than 1 year at a
time.
I don't see a way to display something like 3 years worth of calendar
starting at a point 23 months from now.
(I see how to display 1 year at a time but not multiple years.)


This question seems a little vague. How are you creating this "calendar 
function"? Are you using the Python Standard Library calendar, or 
perhaps talking about datetime calculations?


Please copy-paste code showing this "lock".

Some underlying stream has fast-path for .readall().
So close this issue.
