RE: Popping key causes dict derived from object to revert to object (3/25/2024)

[Dr. F. M. (Mike) Covington via Python-list]

Hello, all.

 

I guess I'm just not seeing this dictionary pop() problem you're having.  

What version of Python are you using?  Is there something I'm missing?

If I've made an obvious oversight, please forgive me and explain.

 

Thanks!

Re: Python 3.12.1, Windows 11: shebang line #!/usr/bin/env python3 doesn't work any more

[Mike Dewhirst via Python-list]

In Windows the provided methods for running complex command lines are either a 
batch file or a shortcut.Someone very kindly pointed out to me in this thread 
that there is a PEP for py.exe. I don't use py.exe originally because I didn't 
trust it believing it was a new-fangled Microsoft trick. I did read that PEP 
but it has no relevance for my mixed Windows/Linux environments. On reflection 
I now believe I won't use py.exe because it introduces an unnecessary layer of 
indirection.The  bottom line is that you still need to know which Python a 
particular set of circumstances demands and if you use py.exe you then need to 
also understand how it chooses and how it interprets shebang lines written for 
your Linux environment. And if that isn't your situation I have jumped to the 
wrong conclusion.I have found no problem in Windows when I use shebang lines in 
scripts intended for execution in both Linux and Windows. They are ignored 
unless you use py.exe.My advice is to give up py.exe unless your use case 
mandates shebang lines in Windows.M--(Unsigned mail from my phone)

I strongly disagree with this.


Not sure which part of the above you strongly disagree with. I might 
seem a bit OTT with "You cannot trust Microsoft" but I did put it in a 
specific context.


PSF does try to make Python work identically in all operating systems it 
supports. The OP was using py.exe which I discovered (just now - and it 
is why I'm writing this) exists on my Windows 10 machine. I have never 
installed any Python other than personally downloaded from the 
python.org website - therefore py.exe must have come from PSF!


I had assumed the OP had installed Python from the Microsoft shop and 
that's where py.exe must have come from.


I learn something every day.

I don't get all the irrational hate for Microsoft that exists within 
the Linux community.


Perhaps you are too young to remember when Steve Ballmer was head of 
Microsoft?


He specifically and loudly hated Linux and developed the anti-linux 
culture/strategy within Microsoft. If memory serves correctly he called 
it a virus. That was in the context of trying to get rid of Linux in 
Europe (Germany I think) where it had gained a small municipal foothold. 
Microsoft eventually succeeded in reversing that public mistake.


In recent years, Microsoft has made great contributions to the 
everyday life of Linux users. VS Code is based on open source and 
available on Linux, .NET is now on Linux, Windows has WSL2 and Visual 
Studio Linux development tools to help you develop software for Linux, 
SQL Server (despite still being commercial software except for the 
Express and Developer versions) is on Linux, etc.


I only use Linux on servers without GUI. I have used Windows desktop 
since it was released because most of my clients used it. I had no 
choice. I have been watching what they do for decades.


I agree they appear to have become more civilised in recent years.

Re: Python 3.12.1, Windows 11: shebang line #!/usr/bin/env python3 doesn't work any more

[Mike Dewhirst via Python-list]

Apologies for top posting - my phone seems unable to do otherwise.

Here's my view - which may not be popular.

1. Py.exe is an awful idea. 

2. Installing python in %PROGRAMFILES% is not a good idea

3. Installing Python from a Microsoft shop or server is a bad idea

4. Shebang lines are pretty much redundant now that most python interpreters 
are run from venvs

5. Shebang lines have never had a place in Windows

TL;DR

1. Py.exe is not a standard python thing and learning to rely on it is 
following Microsoft's marketing strategy. That strategy has served them 
brilliantly since the 1980s. They make their environment just different enough 
to force users to invest brainspace to make it work and thereby lock-in their 
users with their own muscle-memory. Very subtle. Not.

2. Installing Python in Microsoft's preferred location wasn't always 
"standard". Python downloaded from python.org always defaulted to C:\PythonXXX. 
I'm not saying that was a perfect location but at least it was (in my case 
still is) nicely visible for researching multiple different pythons. Putting 
deep in Program files does nothing other than hide it. 

3. You cannot trust Microsoft. You can trust Python Software Foundation. Python 
from PSF works the same in all environments - or if not it is a bug. Python 
from Microsoft is tweaked to satisfy their aforementioned strategy of locking 
in users to Windows.

4. Shebang lines are a fallback if you don't wish to type the interpreter 
location before typing your script name. You must know your interpreter 
location to get the shebang line right. Shebangs were never intended as primary 
devices. They are linux/unix things.

5. Shebangs on Windows are a new opportunity for Microsoft to plough its own 
furrow. They are difficult to handle simply because of 4 above.

To finish this rant, I believe it is far better to aim for standardisation 
rather than subtle and annoying differences deliberately designed to supplant 
standards in favour of market dominance.

Merry Christmas all

Cheers

Mike

That answers your specific question. However, I am in awe of people

I feel the same way about regex. If I can find a way to write 
something without regex I very much prefer to as regex usually adds 
complexity and hurts readability.


You might find https://regex101.com/ to be useful for testing your 
regex. You can enter in sample data and see if it matches.


If I understood what your regex was trying to do I might be able to 
suggest some python to do the same thing. Is it just removing numbers 
from text?


The for loop, "for bit in bits" etc, could be written as a list 
comprehension.


pieces = [bit if len(bit) > 6 else "" for bit in bits]

For devs familiar with other languages but new to Python this will 
look like gibberish so arguably the original for loop is clearer, 
depending on your team.


It's worth making the effort to get into list comprehensions though 
because they're awesome.


I agree qualitatively 100% but quantitively perhaps I agree 80% where 
readability is easy.


I think that's what you are saying anyway.

\b  Word boundary
[0-9]{2,7}  2..7 digits
-   "-"
[0-9]{2}    2 digits
-   "-"
[0-9]{2}    2 digits
\b  Word boundary

The "word boundary" thing is to stop it matching where there are 
letters or digits right next to the digits.


For example, if the text contained, say, "123456789-12-1234", you 
wouldn't want it to match because there are more than 7 digits at the 
start and more than 2 digits at the end.



Thanks

I know I should invest some brainspace in re. Many years ago at a Perl 
conferenceI did buy a coffee mug completely covered with a regex cheat 
sheet. It currently holds pens and pencils on my desk. And spiders now I 
look closely!


Then I took up Python and re is different.

Maybe I'll have another look ...

In due course, investigate virtual environments so you can work on

If you are just starting out, the most recent version is 3.12 and is
probably your best choice.

When you say it never worked, can you describe in more detail what you did

zoneinfo and tzdata

[Mike Dewhirst via Python-list]

The zoneinfo module does not work on Windows unless you have installed 
tzdata.


On Ubuntu that data seems to exist already. Not sure how or why but it 
obviously isn't there in a Windows virtualenv unless deliberately installed.


I just spent a bit of time trying to switch from pytz to zoneinfo in 
Django without luck. I then asked and greatly embarrassed ChatGPT which 
kept apologizing when I fed back all the zoneinfo errors its advice caused.


It wasn't until I read the docs that I saw zoneinfo would get timezone 
data from tzdata if the real info wasn't where it first looked.


As soon as I installed tzdata, ChatGPT's advice started to work. When I 
reported this, it was very grateful and assured me my generosity in 
bothering to correct it would be very beneficial for other users having 
similar problems.


Might I suggest that if zoneinfo comes up empty-handed it should raise 
an error saying no timezone information was found?


Currently, it just nominates the timezone key you attempt to use. Behind 
the scenes it surely knows there are no such keys. In that case it might 
suggest installing tzdata.

However I have hit a problem with converting dates, the bash script
has:-

 dat=$(date --date "$1" +"%Y/%m/%d")

and this will accept almost anything reasonably sensible that can be
interpreted as a date, in particular it accepts things like "tomorrow",
"yesterday" and "next thursday".

Is there anything similar in Python or would I be better off simply
using os.system() to run date from the python program?

Prove it works in the command prompt by using the full path to python 
for example,


C:\Python311\python C:\Users\gregg>esptool.py version

If that works, look at your path environment variables and see where 
python is sitting. Substitute the real location of Python 3.11 on your 
machine. Sadly, I think it defaults to C:\Program Files nowadays.


Once you can get Python working by omitting the path, for example,

C:\Users\gregg>python esptool.py version

... you can then right-click the .py file and choose whichever program 
you like to open with.


I'm inclined to advise you to focus on getting virtual environments 
working next and leave all that auto-opening to later. You might find 
you prefer to right click and select every time.

I second this.  "if '-h' in sys.argv:"  is usually what I do.

Alternatively, you could use "--arg=" syntax and place your string 
"-4^2+5.3*abs(-2-1)/2" its right-hand side":

infix2postfix [options] "--infix=-4^2+5.3*abs(-2-1)/2"

This shouldn't be too hard for a user to work with.  You could scan the 
argument list for the presence of "--infix=" and display the help 
message if it isn't there.

This error doesn't look like "-4.3+5 looks like an option" but instead

Not personally a fan of argparse myself, but then I have my own

That is dreadful news! Windows as a dev platform is dead without it. 
That is serious.


Back on topic - Installation hell

I use Windows for historic reasons related to needing to support 99% of 
my customers/dependents who also use it. I'm the only one who also uses 
Linux - but only non-GUI Linux.


Windows works for me as a dev platform because there are so many 
talented Python people out there who make it work. It would be 
impossible otherwise. I would be forced to to learn two GUIs if I had to 
develop on Linux.


I'm here to tell you that dev and production on different OSs works 
without a hitch! For me.


Whoever wrote the installation docs for Windows did a great job. All the 
bases and options are covered. Absolutely no-one could complain that any 
pertinent detail has been omitted.


Some marketing research is indicated. The OP who started this thread 
could define themself in exquisite detail so that installation 
infrastructure including documentation can be developed to suit that 
market exemplar.


I think there are several separate markets. Eg., for someone like me ... 
locked into Windows (but not Microsoft otherwise) and needing to target 
Linux web servers. That would allow a branching of the installation docs 
to home in, say, on virtual envs and multiple Python installations in 
the root of drive C: (well away from "Program files") and so on.


If the OP says they are an educated computer scientist they could become 
a hero and write up a tightly focused set of docs (extracted from the 
comprehensive canonical docs) which assume their particular "market", 
for want of a better term.


The PSF might recognise the effort and be able to promote such a high 
interest from Windows Python devs into funding for Chris Gohlke.

Stefan

Thank you. I should have said this has been working fine for years and 
years until Ubuntu 2022.04 on a new droplet running Apache/2.4.52


I will refactor it one day - especially if the script is implicated. But 
I think I have to learn how to use lsof first!

Python script not letting go of files

[Mike Dewhirst]

I have a script which fetches a production site directly from a 
Subversion repo using svn export


It runs a bunch of commands by calling this little method ...

def trycmd(cmd, log):
    retcode = -1
    ret = f"Trying {cmd}"
    try:
    retcode = os.system(cmd)
    ret = f"\n{cmd} -ok-> {retcode}"
    except Exception as err:
    ret = f"\n{cmd} -fail-> {err}"
    log.write(remove_password(ret))
    return retcode

This is the fetching script (omitting variables at the top) which 
appears to be keeping a finger on files which Apache wants.


with open(fetchlog, 'a') as log:
    ret = f"\n\nFetching {tag}"
    log.write(ret)
    cmd = f"sudo rm -Rf {site_root}"
    if trycmd(cmd, log) == 0:
    cmd = f"sudo svn export --force --username {usr} --password 
{pw} {svn_repo} {site_root}"

    if trycmd(cmd, log) == 0:
    # get any new dependencies
    cmd = f"sudo -H pip install -r {reqfile}"
    if trycmd(cmd, log) == 0:
    # run any migrations shipped from the repo
    cmd = f"sudo python3 {site_root}/manage.py migrate 
--noinput --settings={settings}"

    if trycmd(cmd, log) == 0:
    # shouldn't find anything
    cmd = f"sudo python3 {site_root}/manage.py 
makemigrations --noinput --settings={settings}"

    if trycmd(cmd, log) == 0:
    # should have been done already
    cmd = f"sudo python3 {site_root}/manage.py 
migrate --noinput --settings={settings}"

    if trycmd(cmd, log) == 0:
    # remove all static files from their Apache dir
    cmd = f"sudo rm -Rf {static_root}/*"
    if trycmd(cmd, log) == 0:
    # copy all static files to the Apache 
location
    cmd = f"sudo python3 
{site_root}/manage.py collectstatic --noinput --settings={settings}"

    if trycmd(cmd, log) == 0:
    # set all permissions
    cmd = f"sudo {scripts}/perms_{host}.sh"
    if trycmd(cmd, log) == 0:
    cmd = "sudo service apache2 
restart"

    if trycmd(cmd, log) == 0:
    ret = f"\nFinish {tag}\n\n"
    log.write(ret)
    else:
    print("Apache didn't restart")
    else:
    print("Didn't set permissions")
    else:
    print("Didn't collectstaic")
    else:
    print("Didn't delete static files")
    else:
    print("Didn't migrate 2")
    else:
    print("Didn't makemigration")
    else:
    print("Didn't migrate 1")
    else:
    print("Didn't install requirements")
    else:
    print("Didn't get source")
    else:
    print("Didn't remove site")
exit()

The problem I'm trying to fix is that after an Apache reload Apache 
seems hellbent on filling up its scoreboard and running out of 
resources. The kind folk on the Apache mailing list say something is 
hogging the workers.


You can see the last operation above is an Apache restart. It should be 
an Apache reload. Reload however lets Apache run out of resources.


Do any of you Python folks see any blunders in the above code along the 
lines of not letting go of py files or static assets?

If you can call Python from the shell prompt, then you could remove the

It depends on the operating system.

Typically, you can just install the new version and adjust your 
environment vars (ie., path) to point to the new version instead of the old.


The theoretical reason is that you may have other programs/scripts etc 
which still rely on the old version.


If you are new to Python, you should probably avoid installing later 
versions until you have studied virtual environments. A venv will let 
you keep your "system" Python(s) clean and unencumbered while being able 
to experiment with all sorts of additional libraries, packages etc in 
multiple separate sub-environments.

Why?


Good question.

Further to Peter's explanation, email is the primary conduit for 
hackers. At this point in time human education and training is the only 
defence. The bad guys count on human error because that's what humans 
are good at.


If everyone signed their mail and all mail clients defaulted to 
expecting signed email from correspondents for whom the public key is 
known, some of that defence can be delegated to the computer.


I'm not expecting this any time soon but it doesn't hurt to get the 
message out.


Most email activists demand end-to-end encryption and obviously signing 
email is part of that. However, my view is that email privacy, while 
very important, is an oxymoron. If you need encrypted messages you would 
never use email. You would meet under a waterfall.


So the answer to your question is signed email is easy and if it becomes 
popular it has potential to defeat hackers.

A developer makes products whereas a scientist understands complexities.

After many years you probably already know enough Python to do anything.

Your task as a developer is to understand the relationship between a 
problem (business or scientific) and a maintainable, perhaps packaged, 
product which handles the drudgery and leaves expert judgement to the 
human user(s).


Scrum is the easiest way down that road.

Re: Persistent Error: Python was not found

[Mike Dewhirst]

Jonathan

This is what I would do ...

1.    Download Python from python.org not Microsoft

2.    Install as an expert or custom install to C:\Python310 rather than 
C:\Program files


3.    Ignore this point - I was going to mention VirtualEnv which comes 
later for software development and thereafter you don't need to put 
Python on the Windows path. As I said, ignore this point.


4.    Add C:\Python310\Scripts to the path (system or user)

5.    Add C:\Python310 to the path after C:\Python310\Scripts

6.    Open a cmd prompt and enter python to prove it starts then quit. 
Exit the cmd window


7.    Create a directory in the root of your user profile 
(C:\Users\Jonathan ??) called pythontest


8.    Save 'print("hello world")' in a text file called hello.py in the 
above directory


9.    Open a cmd prompt and type > python 
C:\Users\Jonathan\pythontest\hello.py


Should work.

If you want to execute a python script without first opening a cmd 
prompt, you need a bat file or shortcut which contains the command line 
you want executed. Give that a double-click and it should also work.


If Python is on the path you don't need to specify where it is.

You do need to tell Python what you want it to execute.

It is possible that you can associate .py files with Python but that 
would be a step too far for me.


Good luck

Using HKEY_CURRENT_USER with RegConnectRegistryW() to access a remote
registry isn't well defined and not documented as supported. If it
works at all, the API probably just opens a subkey of the remote
HKEY_USERS based on the string SID (security identifier string) of the
current user. That may fail as not found since user SIDs are unique to
machines, unless it's on a domain.

Bear in mind that the remote registry service is running on the remote
machine as SYSTEM (S-1-5-18) in the non-interactive services session.
If it literally accessed its "current user", then it would open
"HKEY_USERS\S-1-5-18".
In that case, I'll remove 'computer' as a parameter and lock it in as 
None. I'll document why and if I ever need to access a remote registry 
I'll do some research along the lines you suggest.


My case demands execution of this code via login script for end-user 
configuration after the IT department has done a bulk installation 
rollout. One of key items is ComputerName which is in HKLM and needs to 
be in HKCU for whichever user logs in. The application looks in HKCU for 
a unique Device Reference and ComputerName suffices and is attractive 
because it is also the asset number of the machine.

The result of the arithmetic addition `KEY_ALL_ACCESS + KEY_WRITE` is
0x0011_0045, which is wrong and meaningless. Registry key objects do
not support SYNCHRONIZE (0x0010_) access; DELETE (0x0001_)
access isn't needed; 0x_0040 is not a supported key right;
KEY_CREATE_SUB_KEY (0x_0004) access isn't needed; and
KEY_QUERY_VALUE (0x_0001) isn't sufficient.

You should limit the requested access to the specific access rights
that are required for querying and setting values in the key:

 access=(wr.KEY_QUERY_VALUE | wr.KEY_SET_VALUE)


 def setvalue(self, vname, value):
return wr.SetValueEx(self.select(), vname, 0, 1, value)

You shouldn't hard code the value of the data type constant. Use
wr.REG_SZ instead of 1.

The return value of self.select() is a winreg PyHKEY object that wraps
the OS handle for the key object. You're relying on implicit closing
of this handle based on referencing counting. It's cleaner to use it
in a `with` statement, as you would for a file object returned by
open(). For example:

 with self.select() as hkey:
 wr.SetValueEx(hkey, vname, 0, wr.REG_SZ, value)


  lmregistry = Registry(
  hkey=wr.HKEY_LOCAL_MACHINE,
  sub_key="SOFTWARE\WOW6432Node\XXX Technology\AppName",

You really shouldn't open the "WOW6432Node" key directly. It is an
implementation detail of the WOW64 subsystem that runs 32-bit
applications on a 64-bit system. If you need to operate on the
registry keys of 32-bit applications from a native 64-bit process,
open the normal path usin

Windows registry PermissionError

I'm trying to copy a value from HKLM to HKCU for application rollout via 
bulk installation by an administrator but individual Windows user setup.


Getting this ...

which I realise means nothing in this case.


But I would not have been surprised if it worked here but not in the 
field where users are firefighters and definitely not administrators and 
cannot install software on their workstations.

Personally, I write a batch file containing the 'python

assumes python.exe is on the Windows path.


Once tested and working it lets me edit the batch file to adjust the 
payload without having to touch the Windows stuff again.







Thank you!

[issue46751] Windows-style path is not recognized under cygwin

[Mike Kaganski]

Mike Kaganski  added the comment:

I don't remember if I did something special to install it; however, just maybe 
you need to install python39 directly.

> Are you running the 32- or 64-bit version?

64-bit.

> Does Cygwin not use : as a path list separator?

It uses : as path separator:

$ echo $PATH
/opt/lo/bin:/usr/local/bin:/usr/bin:/cygdrive/c/Program 
Files/AdoptOpenJDK/jdk-11.0.7.10-hotspot/bin:/cygdrive/c/Program Files 
(x86)/Common

But obviously, it can't use Windows-style paths in the $PATH (for that reason?).

[issue46751] Windows-style path is not recognized under cygwin

[Mike Kaganski]

New submission from Mike Kaganski :

Using cyqwin 3.3.4-2, and python3:

Python 3.9.10 (main, Jan 20 2022, 21:37:52)
[GCC 11.2.0] on cygwin

Trying this bash command line:

> python3 C:/path/to/script.py

results in this error:

"python3: can't open file '/cygdrive/c/path/to/curdir/C:/path/to/script.py': 
[Errno 2] No such file or directory"

OTOH, calling it like

> python3 /cygdrive/c/path/to/script.py

gives the expected output:

"usage: script.py [-h] ..."

It seems that python3 doesn't recognize "C:/path/to/script.py" to be a proper 
full path under cygwin, while most other cygwin apps handle those fine. E.g.,

> nano C:/path/to/script.py

opens the script for editing without problems.

The mentioned path syntax is useful and supported under cygwin, so it would be 
nice if python3 could support it, too. Especially useful it is in mixed 
development environment, mixing Windows native tools and cygwin ones; using 
such path style allows to use same paths for both kinds of tools, simplifying 
scripts.

[issue46654] file_open doesn't handle UNC paths produced by pathlib's resolve() (but can handle UNC paths with additional slashes)

[Mike Auty]

Mike Auty  added the comment:

I can confirm that url2pathname work with either number of slashes, and that 
open_file appears to have had the file: removed.

However, in even if the check in open_file were bypassed, it calls 
open_local_file, which then strips any host before calling url2pathname, 
meaning the host will never be included if only two slashes are used.

host, file = _splithost(url)
localname = url2pathname(file)

This is what seems to cause the issue when attempting to open 
file://server/host/file.ext on windows, even though 
file:server/host/file.ext open just fine.

The problem that I found, and was in bug #32442, is that pathlib only ever 
returns two slashes, which despite being a valid and correctly formed url, 
can't be opened by urllib.request.urlopen().  Since there doesn't seem to be an 
issue with opening these files (given it works for file:server...) and 
since nt2pathname will produce the correct result, it feels as though open_file 
should have special code on windows to allow servers to be accepted by the file 
handler (open_local_file should probably stay as is to not change the API too 
much).

[issue46654] file_open doesn't handle UNC paths produced by pathlib's resolve() (but can handle UNC paths with additional slashes)

[Mike Auty]

Mike Auty  added the comment:

> Why are you adding `.as_uri()`?

The API we provide accepts URIs, so whilst the example seems a little 
contrived, the code itself expects a URI and then calls open (making use of the 
ability to add open handlers).

> Builtin open() calls C open().

As best I can tell the file handler is defined in urllib/request.py as 
file_open.  This appears to do some preprocessing to remove the file scheme and 
(and explicitly throws an exception if there's a host that isn't localhost) 
before it gets to the C open().  I wondered why it didn't check if it was on 
windows and, if so, construct an appropriate path (since quadruple hash I don't 
think adheres to the URI RFC, but seems to open correctly)?

[issue46654] file_open doesn't handle UNC paths produced by pathlib's resolve() (but can handle UNC paths with additional slashes)

[Mike Auty]

New submission from Mike Auty :

I've found open to have difficulty with a resolved pathlib path:

Example code of:

   import pathlib
   path = "Z:\\test.py"
   with open(path) as fp:
   print("Stock open: works")
   data = fp.read()
   with open(pathlib.Path(path).resolve().as_uri()) as fp:
   print("Pathlib resolve open")
   data = fp.read()

Results in:

Z:\> python test.py
Stock open: works
Traceback (most recent call last):
  File "Z:\test.py", line 12, in 
with open(pathlib.Path(path).resolve().as_uri()) as fp:
FileNotFoundError: [Errno 2] No such file or directory: 
"file://machine/share/test.py"

Interestingly, I've found that open("file:machine/share/test.py") succeeds, 
but this isn't what pathlib's resolve() produces.  It appears as though 
file_open only supports hosts that are local, but will open UNC paths on 
windows with the additional slashes.  This is quite confusing behaviour and 
it's not clear why file://host/share/file won't work, but 
file:host/share/file does.

I imagine this is a long time issue and a decision has already been reached on 
why file_open doesn't support such URIs, but I couldn't find the answer 
anywhere, just issue 32442 which was resolved without clarifying the 
situation...

[issue46377] TimedRotatingFileHandler "midnight" misleading when interval > 1

[Mike Schiessl]

Mike Schiessl  added the comment:

Yes, enforcing interval == 1 or interval == None (which pulls the 
TimedRotatingFileHandler class __init__ default value which is also 1) works 
perfectly with midnight.

I do not see any urge on that topic - as I personally now know the issue :D - 
but I really feel this fix could save someones else's time someday ;) 

So going the "safe" way via deprecation cycle seems to be the right approach

[issue46377] TimedRotatingFileHandler "midnight" misleading when interval > 1

[Mike Schiessl]

Mike Schiessl  added the comment:

i've just checked PR and you're right, something with the PR went wrong.

Anyway, midnight (at least from the wording) specifies the "atTime". (which 
should be midnight). 


Again, if there's (by mistake) an interval bigger than 1 set(which in my mind 
makes no sense along to be used with midnight) things are getting pretty 
intransparent. The midnight handler created a logfile dated with 2021-12-15 
(last night). Took me some time to get this sorted. (I've discovered, that I've 
set 30 in a default value file).

Agreed on the backward compatibility, but I would assume someone using 
"midnight" would not expect any other behavior than "daily at midnight" besides 
using the atTime to modify the rollover time. (my opinion)

[issue46377] TimedRotatingFileHandler "midnight" misleading when interval > 1

[Mike Schiessl]

New submission from Mike Schiessl :

Using the TimedRotatingFileHandler along with "when='midnight'" and interval > 
1, midnight is handled equally to "days" which is a little misleading.

Expectation:
setting when to 'midnight', the file is rotated every midnight (interval value 
should be ignored)

Current behavior:
If 'midnight' is given alongside with an interval greater than 1 (.e.g 5), the 
(internal) interval (24*60*60) is calculated with the given interval -> 
24*60*60 * 5.


In my case, this led to some unforeseeable and unexpected behavior.

Re: Isn't TypeError built in?

[Mike Dewhirst via Python-list]

Thanks Peter ... the problem was all mine.Can't quite remember what it was 
exactly but I introduced a bug in my own code and it manifested down there in 
the bowels of the snake.I suppose that indicates a possible kink to be ironed 
out and if that interests you I am happy to retrace my steps and describe 
it.Fyi, there was nothing out of kilter in the machine. It was in production 
and is stable.CheersMike--(Unsigned mail from my phone)

Any hints welcome ...

During interpreter shutdown, all kinds of things can go weird. The
order that things get destroyed isn't always clearly defined.

Is it possible to do the cleanup work before interpreter shutdown?
Alternatively: maybe take a local reference to the exception types you
need to refer to (just "AttributeError = AttributeError" at top level
should do it), which should keep them alive longer (I think). Worst
case, capture *all* exceptions, then look at e.__class__.__name__ and
match on that.

OK - not solved but resolved anyway.

The Django project was failing on the new server and working fine in dev.

The problem seems to be a mis-export from an old subversion repo.The 
project was being reconstituted on a new staging server from a reloaded 
svn dump from the old (ancient) svn server to the new svn server on the 
same machine.


Resolution "happened" when I updated the (c) notice in all source files 
and recommitted to the new server and re-exported from that. The repo 
looks fine. The log is all there back to the beginning. As a test I have 
deployed from an earlier revision and that all works. It's either a 
miracle or I did something else (which I didn't notice) which fixed it.


Thanks to everyone for thinking about this.

Cheers

Mike

[issue21501] docs: mmap example for use in documentation

[mike mcleod]

mike mcleod  added the comment:

One of the things I did when the example code didn't work was to see what other 
examples could be found and there are I would argue plenty or just enough, eg:
https://medium.com/analytics-vidhya/memory-mapping-files-and-mmap-module-in-python-with-lot-of-examples-d1a9a45fe9a3
And google will fetch more if needed.
May I suggest back in 2014 when the issue was raised that this may have been a 
good example, but mmap is not so new and in the intervening time anybody who 
needed further examples simply googled them. Hence, I suggest its not needed.

[issue21501] docs: mmap example for use in documentation

[mike mcleod]

mike mcleod  added the comment:

I would like to help with this issue.
I note that a few changes need to be made to the code example for compatibility 
for the latest version of Python. I can get this working but I am not sure this 
is a good example. Also, the example is more about threads and messaging 
between threads rather than mmap.
So my question is is this a good example?
And the suggestion of adding detailed explanation of the code, again, as to 
what it does not seem to be that relevant to mmap.

Hi  Éric,

Then would the easiest way of dealing with this issue, to close it without
any further work?
Possibly adding to the documents it doesn't work on windows..
I can move to the next issue.

Regards,
Mike

[issue2628] ftplib Persistent data connection

mike mcleod  added the comment:

I am happy to do any testing.
My reason for getting involved is I am new to helping with Cpython and thought 
this may be the least intrusive way of getting started with something that 
nobody really cares about that much.
Hence, the oldest issue I see can be either completed as first envisioned or 
can be closed and I am ok with either.
