[issue46425] Multiple test modules fail to run if invoked directly

[Nikita Sobolev]

Nikita Sobolev  added the comment:

Important note, in practice there's also a difference in how one calls some 
test module:

- python Lib/test/test_contextlib.py
- python ./Lib/test/test_contextlib.py

Example of a test failure because of that:

[issue46399] Addition of `mapping` attribute to dict views classes has inadvertently broken type-checkers

[Inada Naoki]

Inada Naoki  added the comment:

I am not happy about exposing every internal types. I prefer duck typing.

Like OrderedDict, not all dict subtypes uses `dict_keys`, `dict_views`, and 
`dict_items`.
If typeshed annotate dict.keys() returns `dict_keys`, "incompatible override" 
cano not be avoided.

I prefer:

* Keep status-quo: keys().mapping cause false positive and user need to 
suppress. This is not a big problem because `.mapping` is very rarely used.
* Or add `.mapping` to `KeysView`, `ValuesView`, and `ItemsView`. Force every 
dict subclasses to implement it.

Re: What to write or search on github to get the code for what is written below:

[Avi Gross via Python-list]

I do not manage any python lists or have any say in how they run so I have no 
idea why I am being asked by name below, as Dennis pointed out.
So I won't reply on whatever I am being asked, but want to point out that many 
forums may be asked questions and some people on the forum will not respond or 
will not accept a user that bombards with too many questions or requests for 
more detailed answers and especially when not given enough but appropriate 
information.
Not everything in life is free. Python as a free language is but the expertise 
in ways to solve specific problems using Python, let alone EXCEL, that you 
want, often is not.
Simple requests like how to read in data from a format like .CSV or a tab in 
.XLSX files can be easily answered, of course. But correcting what sounds like 
a horrible data storage without a redesign is often not of much interest to 
others.
I think this group has already spent way too much time on whatever this issue 
is and provided lots of useful advice which apparently does not get taken. So 
don't pull me in again. I have moved on.

>Avi Gross:

    Not Avi Gross, but that is partly because you replied to Chris
Angelico, who was replying to my post replying to an earlier one of
yours...

>What does the website "https://mail.python.org/mailman/listinfo/python-list;

>Can I use this for the discussions which I require?

    It is most likely the same forum...

    The Python mailing list (which does get spam filtered, unlike the
Usenet newsgroup, so doesn't see as much junk injected via Google) is
gatewayed with Usenet comp.lang.python. comp.lang.python is what Google
gateways for its Python group. Anything posted on the Google Python group
is seen by comp.lang.python, and from there gets seen by the Python mailing
list (and things go the other way also). The only difference is message
management -- email vs news reader vs whatever Google's interface of the
week inflicts, and how much spam comes through. For me, mailing lists take
too much management to set up filters to file mailing list traffic to a
special mail box (and then if I need other filters, to ensure they apply
before or after the mail box filing) whereas a decent news reader
automatically files messages by their group.









    And you really need to find a client that follows (or properly use the
one you have) email/netnews /threading/ and attribution conventions. Avi
Gross's post was on a different path (there was a three-way split from your
earlier post).

    If you are going to be explicitly asking questions of a person, that
post should be a follow-up (reply) to the nearest relevant post made by
that person -- not just tacked onto the end of the posts that came in
during the day with all content removed and ad hoc comments inserted.

[Jelle Zijlstra]

Jelle Zijlstra  added the comment:

The types of `.keys()`, `.items()`, and `.values()` on 
`collections.OrderedDict` are distinct from those for dict, and they are also 
not exposed anywhere. Should we put them in a public, documented place too for 
consistency?

>>> import collections

[issue46392] MessageIDHeader is too strict for message-id

[bpoaugust]

bpoaugust  added the comment:

Sorry, I think '' is not valid, as spaces are not allowed between 
words.

However I am not seeing the original unfolded source if there is an error, 
unless I am misunderstanding the API.

For example:

--- cut here ---
import email.header
import email.utils
import email.policy

def test(test):
msg_string = f"Message-id: {test}"
message = email.message_from_string(msg_string, policy=email.policy.default)
out = message['Message-id']
print(test)
print(out)

test('') # invalid
test('') # valid
--- cut here ---

This produces:


 # truncated at error



i.e. the invalid input is truncated

[issue46425] Multiple test modules fail to run if invoked directly

[Nikita Sobolev]

Nikita Sobolev  added the comment:

Terry, yes I am using this script to run tests locally:

```bash
#!/usr/bin/env bash

set -e

while read line; do 
  ./python.exe "$line"
done < files.txt
```

And this one to populate `files.txt`:

```bash
find ./Lib -iname 'test*.py' -o -iname '*tests.py' -exec echo {} >> files.txt \;
```

---

There are several other problems that I have to fix manually. For example, 
module-level `raise unittest.case.SkipTest()`:

```
» ./python.exe Lib/test/test_winreg.py 
Traceback (most recent call last):
  File "/Users/sobolev/Desktop/cpython/Lib/test/support/import_helper.py", line 
77, in import_module
return importlib.import_module(name)

  File "", line 1178, in _find_and_load
  File "", line 1142, in _find_and_load_unlocked
ModuleNotFoundError: No module named 'winreg'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/Users/sobolev/Desktop/cpython/Lib/test/test_winreg.py", line 11, in 

import_helper.import_module('winreg', required_on=['win'])
^^
  File "/Users/sobolev/Desktop/cpython/Lib/contextlib.py", line 155, in __exit__

81, in import_module
raise unittest.SkipTest(str(msg))
^
unittest.case.SkipTest: No module named 'winreg'
```

I am not sure what is the proper solution to this one :thinking:

Probably, I will update my script for more advanced Python-based one and ignore 
this exception.

In the end, I expect to run this script without any failures. This is going to 
be a great result! 

---

I will also check that all possible modes `python -m test test_xyz` / `python 
-m test.test_xyz` / `python Lib/test/test_xyz.py` are supported.

---

Also, thank you for listing concrete problems with my first submission. The 
second one is bound to a single problem and a single submodule.

[issue45554] multiprocessing exitcode is insufficiently documented

[Eryk Sun]

Eryk Sun  added the comment:

PR 30142 is sufficient for Unix, but it's missing a bit for Windows.

In Windows, the C runtime library maps the console event for Ctrl+Break to 
SIGBREAK. The default handler for SIGBREAK exits with 0xC13A (i.e. 
STATUS_CONTROL_C_EXIT). This value is unrelated to the value of signal.SIGBREAK 
(21) or signal.SIGINT (2).

To forcefully terminate a process, Windows taskkill and Task Manager, and 
pretty much all utilities that can kill a process, call TerminateProcess() with 
1 as the exit status. There's no way to know that this is a forced termination 
as opposed to an unhandled error.

The internal terminate() method in Windows uses 0x1 as the real exit status 
of the process, but the internal wait() method maps this to -signal.SIGTERM 
(-15). Thus the case of calling Process.terminate(), and only this case, is 
faked in Windows to look like the process was killed by a signal.

Re: Trouble downloading Python

Insufficient information (you've given the equivalent of "my arm hurts"
without stating which arm, where it hurts, and the nature of the pain; a
big difference between "it was caught in a door jamb" and "a chainsaw cut
it off").

Where are you downloading from (the URL might be of use), which version
(if there are more than one version at that URL). WHAT OS! For Linux it is
often easiest to just use the distribution package manager to
install/upgrade Python.

What happens when you run the downloaded file? How are you trying to
run Python?

What happens if you open up a command shell and enter just Python (or,
for safety python3, since you shouldn't even be looking at python 2.x but
some Linux distributions still use 2.x for there own uses)

Python is not a development environment. It is a compiler/interpreter
for files containing Python source code, normally run from a command shell.
Many installations do include a Tkinter-based program called IDLE which can
be run if one really needs an IDE -- though there are many third-party IDEs
for Python which may be better.

Re: What to write or search on github to get the code for what is written below:

[Dennis Lee Bieber]

o/~ talking to myself in public o/~

On Mon, 17 Jan 2022 15:39:25 -0500, Dennis Lee Bieber
 declaimed the following:


>   In one respect, given the limited functionality stated, one gets the

I'm in a fey mood today... The OP (and the rest of you reading) will
likely just skip this message... It's a rambling free-association harangue
on a possible RDBM schema -- which makes a few assumptions (described
following) and looks wildly different from the OP's vague data...

Inferred from various posts is that this
*   NOT a library (which may have at most 5 copies of 
popular
books)
*   NOT a book store (which would not have 
check-out/check-in
dates)

The best use case I can see is for something like a high school in
which textbooks are issued to students at the start of the course, and
collected at the end. For a small high school, say 600 students, there
might be 150 taking, say 3rd year Trigonometry, split among 6 session of 25
students each day. This justifies not tracking every copy of a book by full
title, et al.

I'm going to take that as the overall system CONOPS.

Needed data: book title, book author(s), ISBN and/or other call number
(some texts may be old enough to predate ISBN), # copies, # available,
dates for check-out and return, student name. Probably more as I go down...

Schema format notation:

relation(attribute list)
special constraints description

where 
*attribute* is a non-null, unique index, primary key (preferably
autonumber)
_attribute_ is a non-null, duplicates allowed index, foreign key (in
the form relation-attribute)
/attribute/ is an optional/alternate indexed attribute

Publisher(*ID*, name)

Book(*ID*, ISBN, alt-call, title, _Publisher-ID_, copyright-date)
constraint(ISBN not null OR alt-call not null)

Author(*ID*, /last-name/, first-name)
constraint(last-name not null)

Book-Author(*ID*, _Book-ID_, _Author-ID_)
{this links authors to books, and allows for books to have more than
one author}

Copy(*ID*, _Book-ID_, copy-number, status, condition)
constraint(status in "A", "O", "R", status not null, default "A")
constraint(copy-number not null, [Book-ID copy-number] is unique)
{A = available, O = checked out, R = reserved but not yet 
checked
out}
{condition contains notes on known damage, etc. for this copy}

Student(*ID*, /last-name/, first-name)
constraint(last-name not null)
{I expect this to expand with student ID number, home address,
etc.)

CheckOut(*ID*, _Copy-ID_, _Student-ID_, reservation-date, checkout-date,
due-date, active)
constraint([Copy-ID Student-ID] is unique)
constraint(active not null boolean default true)
{can automate cancelling reservations after n-days, and can 
also be
used to produce a list of past-due}
{active is used to allow for history of check outs, set to false
when book is returned (and hence made Available again)

SEVEN relations (aka "tables") in an RDBM. While each book /title/
appears only once, it does take a small record to identify each copy of the
book and track availability of the copy. Reserving a book requires
transaction to select the first copy with status = "A" for that title,
update status to "R", insert a checkout record with the currently selected
student and current date for reservation date. When actually given the
book, a transaction to find the active checkout record for the student, for
that title is done, the checkout and due dates are set, the copy record is
updated for status = "O". When returned, a transaction is done to locate
the checkout record, update active to false, update Copy record to set
status to "A", and optionally update the condition field to indicate
damages inflicted by the student while it was checked out. If a reserve
operation fails (another session snagged the same copy record and updated
it) one just repeats the transaction trying for the next available copy
record -- only if there are no copies with status "A" do you have to abort
and tell the student they can't have the book.

[issue15500] Python should support exporting thread names to the OS

[Antoine Pitrou]

Antoine Pitrou  added the comment:

Two things:

1) I agree this is an extremely valuable addition for any package or 
application that does a non-trivial use of threads in Python.

2) It should at least be exposed as a standalone function in the `threading` 
module, *and* ideally also be called automatically by the 
`Threading._bootstrap` method.

For now, Python thread names are always empty (as in many other programs). So 
Python-oriented tools that could expect some other outcome to bother check the 
names are just impossible (there is no alternative semantics they could perform 
in non-empty case).

[issue46392] MessageIDHeader is too strict for message-id

[R. David Murray]

R. David Murray  added the comment:

The general idea is that the string version of the header should contain all of 
the original information, but the parsed elements (the things returned by 
special header attributes) will contain the valid data, if any.  So if the 
string version of the header is being truncated or transformed (other than 
whitespace changes during re-folding), that is a bug.

Your examples involve comment fields, and I'm afraid that my development of the 
parser stopped before I did very much with comments.  Therefore I am not 
surprised that comments are handled incorrectly :( :(  They aren't very common 
in the wild, as far as I was able to tell. which is why they were my last 
priority.

Not Avi Gross, but that is partly because you replied to Chris
Angelico, who was replying to my post replying to an earlier one of
yours...

>What does the website "https://mail.python.org/mailman/listinfo/python-list;

It is most likely the same forum...

The Python mailing list (which does get spam filtered, unlike the
Usenet newsgroup, so doesn't see as much junk injected via Google) is
gatewayed with Usenet comp.lang.python. comp.lang.python is what Google
gateways for its Python group. Anything posted on the Google Python group
is seen by comp.lang.python, and from there gets seen by the Python mailing
list (and things go the other way also). The only difference is message
management -- email vs news reader vs whatever Google's interface of the
week inflicts, and how much spam comes through. For me, mailing lists take
too much management to set up filters to file mailing list traffic to a
special mail box (and then if I need other filters, to ensure they apply
before or after the mail box filing) whereas a decent news reader
automatically files messages by their group.









And you really need to find a client that follows (or properly use the
one you have) email/netnews /threading/ and attribution conventions. Avi
Gross's post was on a different path (there was a three-way split from your
earlier post).

If you are going to be explicitly asking questions of a person, that
post should be a follow-up (reply) to the nearest relevant post made by
that person -- not just tacked onto the end of the posts that came in
during the day with all content removed and ad hoc comments inserted.

[issue46427] Correct MSBuild's configuration for _freeze_module.exe

[neonene]

New submission from neonene :

In pcbuild.proj, "PreferredToolArchitecture" property looks misused, which I 
think is useful giving us two selections of a compiler (32bit or 64bit) for any 
target architecture (Win32/x64/ARM/ARM64).

I think the property can be unused there. This means a partial revert of 
PR28491, whose description I cannot reproduce. This also rolls 
_freeze_module.exe's architecture back to x64 when the target platform is x64 
or ARM64.

[issue46425] Multiple test modules fail to run if invoked directly

[Terry J. Reedy]

Terry J. Reedy  added the comment:

Nikita, thanks for doing this.

Ethan's suggestion has two advantages. 1. It would fix most backport issues.  
By containing a mix of changes, PR-30666 cannot be backported as is.  
'unittest.main' should always backport unless there is a context conflict.  But 
3.9 does not have os.helper and TESTFN is still in test.support in 3.9 and that 
change cannot backport.  (I did not check 3.10.)

2. It restricts the knowledge needed to review (and be willing to merge).  I 
could and would review and merge a patch with only unittest.main changes, but 
not, without checking the docs to learn about new changes, the mixture you 
posted.

I suggest you write a script to directly run each test.test_xyz file via 
subprocess and report to stdout.  The test for this issue is a clean report.  
If you do so, I will run it on Windows in a fresh build of each of 3.9, 3.10, 
and 3.11.

Note that there are two possible commands: 'python -m test test_xyz' and 
'python -m test.test_xyz'.  They are subtly different.  So I would add an 
option to do it each way.

With current 3.11, test_importlib runs fine on my Windows, with 1436 tests.

Re: About Python Compressed Archive or Binaries

[Sina Mobasheri]

Thanks I really appreciate that, its time consuming task and take lots of hard 
work for sure, I was thinking it's technical issue for python that there isn't 
binary format for it, so I'm happy to hear that we will have that option in the 
future 

Java is developed by Oracle (revenue 49 billion USD)
.NET is developed by Microsoft (revenue 161 billion USD)
Go is developed by Google (revenue of parent company is 182 billion USD)
Python is developed by a bunch of (mostly unpoaid) volunteers under the
umbrella of the PSF (revenue 3.1 million USD).

Do you see a pattern? :)

A distributable binary format for CPython is high on our list. Brett
Cannon, Nathaniel Smith, and I have been discussion a proposal recently.
I landed a bunch of changes in 3.11-dev that are both useful for binary
distribution and for Web Assembly builds. Because all work is done in
our free time, there is only little progress.

[issue46426] Improve tests for the dir_fd argument

[Serhiy Storchaka]

New submission from Serhiy Storchaka :

There is a flaw in tests for the dir_fd argument in test_posix. All these tests 
open a current directory as dir_fd, so all paths are relative to the current 
directory. They will pass in case of the following errors:

1. dir_fd, src_dir_fd or dst_dir_fd are completely ignored.
2. The meaning of src_dir_fd and dst_dir_fd is opposite.

The proposed PR rewrites these tests. It is ensure that directory file 
descriptors refer to directories different from the current directory, and that 
src_dir_fd and dst_dir_fd refer to different directories, and that all tested 
filenames are unique, so files cannot be confused with existing diles in 
different directories.

Also add context manager open_dir_fd() in test.support.os_helper. It may be 
helpful in other tests for the dir_fd argument.

[issue46425] Multiple test modules fail to run if invoked directly

[Nikita Sobolev]

New submission from Nikita Sobolev :

While working on a similar issue for `test_typing.py` 
(https://bugs.python.org/issue46416) I wondered: how many other modules also 
have this problem?

So, after several hours of local testing, I got several problems:
- Lib/test/test_compileall.py
  Uses relative `.` import that cannot be resolved

- Lib/test/test_distutils.py
  Is missing `import unittest` to run `unittest.main()`

- Lib/test/test_dtrace.py
  Calls undefined `test_main()` instead of  `unittest.main()`

- Lib/test/test_tools/test_freeze.py
  Uses relative `.` import that cannot be resolved

- Lib/test/test_zipfile64.py
  Imports undefined `from test.support import TESTFN`

- Lib/unittest/test/test_program.py
  Uses relative `.` import that cannot be resolved

Probably there are other problems, because I haven't checked:
- Windows tests, because I don't have a Win machine
- `test_importlib`, because it has a lot of failure (I don't know how to fix 
them yet)
- Multiple other modules with slow tests
- Modules with doctests which assert full `__qualname__` with module names

To keep PRs reviews sane, I will include changes for several modules and split 
this big task of checking all test modules into several consecutive and rather 
simple pull requests. 

The first one with the problems described above is on its way!

The part of this that is Set up Environment Variables and PATH can be
handled by Python's virtualenvs.  You create one starting from a
possibly local Python layout, or from a system one, and the virtualenv
handles all the "fiddling" so while that env is active, just "python"
and "pip" work for that environment.

A nice way to manage this is through a project called pyenv.  There is
now a Windows port of this so it can work there as well (I've never used
it on WIndows, personally).

So while there may not currently be a zip/tar archive you can unpack and
go, I can get started quite easily on a new version.  Let's say I
decidded I needed to test something on Python 3.7 but my main Python is
already 3.10:

pyenv install -l | grep "3\.7"
... list of available versions that contain 3.7

pyenv install 3.7.12   # sets up 3.7.12 in pyenv's local versions tree
pyenv virtualenv 3.7.12 venv-3712  # create virtualenv using 3.7.12 as base
pyenv activate venv-3712

and now I'm running inside a virtualenv using 3.7.12, which I can now
provision for the work I want to do...

Java/DotNet/Go have this option. But python - not.
