[issue43968] os.path.realpath() unexpected breaking change: resolves subst'd paths to real paths

[Eryk Sun]

Eryk Sun  added the comment:

A substitute drive is not a mount point, strictly speaking. It's a symlink in 
the object namespace that targets an arbitrary path on a device, or even on 
another mapped/substitute drive. A mapped drive is a similar case that targets 
an arbitrary path on a UNC share. Any number of these path components may be 
filesystem symlinks, which can in turn target other substitute drives and 
mapped drives.

The object manager reparses your example substitute drive "Z:" to its target 
path r"C:\example\dir" before the I/O manager and filesystem ever see the path. 
Thus, hypothetically, if r"Z:\symlink" targets r"\spam", it resolves to 
r"C:\spam", not r"Z:\spam", i.e. not r"C:\example\dir\spam". If r"Z:\symlink" 
targets r"..\spam", it resolves to r"C:\example\spam". 

Also, substitute drives are almost always defined for the current logon session 
only. If you think it's not an issue because you're the only user on the 
machine, there's still typically a linked logon to worry about in the case of a 
UAC split standard/administrator logon; plus there are service processes 
running as SYSTEM, NETWORK SERVICE, and LOCAL SERVICE; and maybe also 
non-interactive tasks running as the user account in a separate logon session. 
Given that Windows is inherently a multiple-logon system, a path that's only 
accessible by one logon session in the system is not the best candidate for a 
real path if it's possible to resolve it further to a path that's globally 
accessible.

---

A mount point, unlike a symlink, is a graft point that behaves like a regular 
subtree. Classical mount points in Windows are the root paths of volume devices 
(e.g. "C:\\", where "C:" is a volume device name) and redirected filesystems 
mounted as UNC shares (e.g. r"\\server\share"). Windows 2000 added support for 
bind mount points (i.e. junctions, e.g. r"C:\Mount\F"). Unfortunately, 
switching to junctions probably won't solve your problem. The current design of 
ntpath.realpath() doesn't always retain a bind mount point in the resolved 
path, not unless it's the canonical path of a local volume -- or unless it's in 
a UNC path since it's impossible to resolve a remote junction to an accessible 
target path.

[issue43972] Simple HTTP Request Handler in http.server does not set a content-length and does not close connections on 301s

[Stephen Rosen]

New submission from Stephen Rosen :

If you use the `http.server` simple server and handler to serve a directory, 
navigating to a directory name without a trailing slash will trigger a 301 to 
add the trailing slash.

For example, if "foo/" is a directory under the file server, a GET for "/foo" 
will receive a 301 Moved Permanently response with a Location header pointing 
at "/foo/".

However, the response is sent without a "Content-Length: 0" and the connection 
is not closed. Unfortunately, certain clients will hang indefinitely and wait 
under these conditions, without processing the redirect. In my testing, curl 
7.68 and Firefox 87 both exhibted this behavior.

If a Content-Length header is set, these clients behave correctly.
For example, subclass the handler and add

def send_response(self, code):
super().send_response(code)
if code == HTTPStatus.MOVED_PERMANENTLY:
self.send_header("Content-Length", "0")

[issue1227748] doc: subprocess: inheritance of std descriptors inconsistent

[Eryk Sun]

Eryk Sun  added the comment:

> If one calls Popen with stdin = stdout = stderr = None,
> the caller's std descriptors are inherited on *x, but
> not on Windows

In the default case, CreateProcessW() is called with bInheritHandles as false 
and without explicitly setting the standard-handle values. Also, creationflags 
is 0 in the default case, not CREATE_NEW_CONSOLE, CREATE_NO_WINDOW, or 
DETACHED_PROCESS. In this case, the child's standard handles are implicitly 
duplicated from the parent if the child shares the parent's console session. 
Contra "1227748.patch", the standard handles are not "attached to the console 
window". For example, if the parent's stdout is redirected to a handle for an 
open disk file, the child's stdout will be redirected to the same open file. It 
has nothing to do with a window, and the console session doesn't even need to 
have a window (i.e. created with CREATE_NO_WINDOW; or a pseudoconsole session).

In particular, if the executable image of the child is a console application, 
the system duplicates the parent's standard handles to the child, as well as a 
handle for the parent's console session, if any. If the child can connect to 
the parent's console at startup, then the duplicated standard handles are used, 
whatever they are. (In general, they need to be handles for pipe, character, or 
disk files opened in synchronous mode, as required by C standard I/O.) If the 
child can't connect to a console session, it allocates a new console and opens 
the console "Input" and "Output" as its standard handles. 

On the other hand, if the executable image of the child is not a console 
application, the system does not implicitly duplicate standard handles from the 
parent to the child. The window manager and graphical shell even explicitly 
reuse the standard-handle values (via STARTUPINFO) to implement features that 
aren't I/O file related when running GUI apps, including configuring an 
activation hotkey (stdin) or passing a handle for the preferred output monitor 
(stdout).

[issue43908] array.array should remain immutable

[Pablo Galindo Salgado]

Pablo Galindo Salgado  added the comment:

In any case, that's my personal opinion of course.

What we should do is decide collectively if immutability is defined behaviour. 
If we decide that it is, we need regression tests. If we define that as "nice 
to have" but ultimately "implementation-defined" we don't.

In any case, I would argue that having tests is good and allow us to know when 
the behaviour flips without people intending it to, like what happened in this 
case.

[Serhiy Storchaka]

Serhiy Storchaka  added the comment:

I am not sure tests are needed here. Immutability of the type is mainly an 
implementation detail. We keep the types immutable because we don't want users 
to use the feature of mutating these types. I don't think anything bad will 
happen if in some Python implementation some of these types are Python classes 
and are mutable. It is not easy to make a Python class immutable. Users will 
not intentionally write a code depending on mutability of these types because 
it does not work in CPython.

[issue14243] tempfile.NamedTemporaryFile not particularly useful on Windows

[Paul Moore]

Paul Moore  added the comment:

To be explicit, I'm +1 on breaking backward compatibility in the minor form 
described by Ethan: if NamedTemporaryFile is used as a context manager, the 
file is closed *on context manager exit* and *not* when the file is closed.

Breaking compatibility is allowed in minor versions (3.11 at this point, as 
this won't make it in before 3.10 feature freeze). So this is an acceptable 
change.

I don't personally think this needs a transition period or deprecation, and in 
particular I don't think that Jason's "gradual transition" proposal is 
necessary.

I'd be sad if we ended up with an over-complicated solution for no better 
reason than an excess of caution over a backward compatibility issue that we're 
not sure will impact anyone. Do we have any actual examples of code that needs 
the current CM behaviour (as opposed to a general concern that someone might be 
using the functionality)?

(My original over-complicated proposal was based on a mistaken belief that it 
had already been established that backward incompatibility was absolutely not 
allowed. But I never subscribed to that view myself.)

[issue43969] "bad magic number" when Python 2's pyc file exists without py file

[Mitchell Hentges]

New submission from Mitchell Hentges :

Python 3 imports may fail if a Python 2 .pyc file exists without an 
accompanying .py file.

-

My project vendors code, and we recently updated "requests" to a drastically 
newer version.

As part of this version change, `requests/packages/__init__.py` was removed, 
and  `requests/packages.py` was added.

This project is long-lived, and many people have imported `requests` with 
Python 2. So, `requests/packages/__init__.pyc` exists.

After making this update, importing requests with Python 3 fails:
`ImportError: bad magic number in 'parent.child': b'\x03\xf3\r\n'`

Interestingly, deleting `requests/packages/__init__.pyc` allows Python 3 to 
work again.

-

I've attached a "reproduction" script that produces the directory structure and 
tweak required to cause the failure.
I'm running Python 2.7.18 and Python 3.9.1.

Separately to my previous message. If the only issue with my PR is that default 
solution is not portable, then this can be simply changed within current PR by 
setting default of delete_on_close to fe equal to False.

As I mentioned, I was assuming I cannot break backwards compatibility.

[issue14243] tempfile.NamedTemporaryFile not particularly useful on Windows

[Evgeny]

Evgeny  added the comment:

Dear all, thank you very much for the discussion, I will just try to summarize 
the results of it.


In my PR I used solution, proposed by Eryk. My solution involves introduction 
of the extra flag delete_on_close and making sure, that new situation is fully 
backwards compatible, because I did not feel I have an authority to propose 
anything which would break backwards compatibility (as Python 4.0 I think is 
not on the horizon yet)


As I see from the discussion, the following decisions need to be taken:

WHICH FLAG TO USE

Eryk was proposing that it shall be delete_on_close  (which I have implemented)

Jason thinks, that we shall introduce flag delete_when, however when I read his 
proposal, the functionality which he proposes is not that different from what I 
implemented with  delete_on_close.

Ethan however thinks, that no extra flags are necessary at all



USAGE OF O_TEMPORARY ON WINDOWS

Ethan, Steve thinks, it is not needed

Eryk prefers to provide a way to omit O_TEMPORARY, but still use it by default, 
when it's omitted



CHANGING OF THE CURRENT BEHAVIOUR / BREAKING BACKWARDS COMPATIBILITY
Ethan thinks, that we shall slightly change backwards compatibility in a way 
that if CM is used, than file is deleted on CM exit and not on close as now

Jason thinks that backwards compatibility shall be changed gradually over 
several releases with the advanced depreciation warning 

Question: does everybody definitely agree then, that backwards compatibility 
shall definitely be altered, whether immediately or gradually?



Any other decision to be taken which I missed?


CONCLUSION: 
There seems to be still disagreements and I don't really know how to move this 
forward as  I am not sure I understand the decision making mechanism in the 
Python community (especially when it comes to breaking backwards 
compatibility). Any thoughts on this?

Pablo Galindo Salgado  added the comment:

Because all static types are immutable, and some have been converted to heap 
types changing the contract, therefore is a regression and therefore we need 
regression tests for those.

[issue33040] Make itertools.islice supports negative values for start and stop arguments for sized iterable object

[Yaroslav Nikitenko]

Yaroslav Nikitenko  added the comment:

I hope it's fine to add to closed topics here.

I agree with the decision that islice should not handle a special case of sized 
containers vs iterables.

However, I think that the support of negative indices in islice would be nice. 
A simple use case would be to get the last element of an iterable.
I had to write my own code for that (you may read and/or use it if needed), 
because I needed this algorithm in my analysis. Here is the link to my function 
ISlice._run_negative_islice in my architectural framework for data analysis: 
https://github.com/ynikitenko/lena/blob/master/lena/flow/iterators.py#L150 or 
on https://lena.readthedocs.io/en/latest/flow.html#lena.flow.iterators.ISlice 
(I'm afraid the correct link might change later).

I also agree that to support negative indices would require more work. Indeed, 
it seems that for each combination of positive/negative start/stop it required 
a new algorithm! I didn't implement negative steps.

However, I think that because it's not easy to implement, it would be even 
better to include that in the standard library (because it would save other 
people from writing that).

If we care about code reuse: I think that negative indices make the algorithm 
more useful, while non-trivial steps are redundant, because they can be 
implemented by a composition of a slice with step=1 with a simple slice with 
start, stop=None, None with step!=1.

Negative slice fundamentally changes the algorithm: if one wants to have the 
flow inverted, fflow[0, None, -1], one would have to store it all in memory! 
Anyway it's easy to make this in a separate function. So I think it's more 
functional to implement negative indices and discard negative steps (or 
non-trivial steps at all).

About drop_first, drop_last suggested above: I also think that they are 
redundant and would be better incorporated into islice.

[issue42998] pathlib.Path: add `username` argument to `home()`

[Barney Gale]

Barney Gale  added the comment:

So far I've been keen to keep the Path and AbstractPath APIs the same, but 
perhaps this case warrants an exception.

What if AbstractPath lacked both home() and expanduser(), and those methods 
only existed on Path? Of all the methods on Path, these two are the *least* 
useful for non-local filesystems.

We can then circle back round to this issue when the fate of expanduser() 
becomes clearer.

Does that sound any good?

[issue43968] os.path.realpath() unexpected breaking change: resolves subst'd paths to real paths

[sfmc]

New submission from sfmc :

For example if I mount directory
  C:\example\dir
to
  Z:\
the
  os.path.realpath('Z:\\')
returns the real directory.

Use following commands in Windows to reproduce the issue:

  md C:\example\dir
  subst Z: C:\example\dir
  python.exe -c "import os; print(os.path.realpath('Z:\\'))"

Python 3.8 outputs:
  C:\example\dir
Python 3.7 outputs:
  Z:\

This is unexpected behavior change and it breaks our scripts in many places, 
because we use mounts in Windows ("subst" command) and Linux ("mount" command).

We had to add our own implementation for realpath to our scripts, but it also 
affects other tools, such as Python debugger (breakpoints stopped working) and 
IDEs (such as PyCharm).

It can be argued whether the behavior to resolve mounts is good.

But this change breaks the ability to work with Python scripts in mounts.
I hope it can be fixed in Python 3.8.10.


I propose to fix it in Python 3.8.10 by adding to function
os.path.realpath(path)
a new parameter (named for example "resolve_mounts"), like that:
os.path.realpath(path, *, resolve_mounts=False)

And if resolve_mounts==False, then the function should not resolve mounts in 
Windows ("subst" command) and Linux ("mount" command).


Let me know if you wish to get a Pull Request with the proposed fix. I can try 
to implement it.

[issue43851] Optimise SQLite builds on macOS and Windows

[Erlend Egeberg Aasland]

Erlend Egeberg Aasland  added the comment:

Here's a list of the SQLite recommended compile-time options (only):

- macOS (v11.2.3) (SQLite v3.32.3) defines SQLITE_DEFAULT_WAL_SYNCHRONOUS=1
- Homebrew (SQLite v3.35.4) does not define any of the recommended compile-time 
options
- Debian Buster (SQLite v3.27.2) defines SQLITE_LIKE_DOESNT_MATCH_BLOBS
- Ubuntu 20.04 (SQLite v3.31.1) defines SQLITE_LIKE_DOESNT_MATCH_BLOBS

AFAICS, adding SQLITE_DEFAULT_MEMSTATUS=0 and SQLITE_OMIT_AUTOINIT is safe, as 
it only affects the C API that we use, and nothing else.

The last of the patches have landed. Guido, thank you so much for helping me

PS: I need to send in a bugfix for typing.py later to ignore ``ParamSpec`` in 
the ``__parameters__`` of invalid locations like ``typing.List`` (this just 
ensures consistency with the builtin ``list``). That can be done as a bugfix 
patch after the 3.10 beta freeze (as it isn't a new feature at all). I'll open 
a new issue after beta 1 for that when you're back. Thanks!

If you come up with a clear improvement for adding link targets, please open it 
in a separate tracker issue.  The other proposals in this thread have all been 
mostly voted down.

I don't disagree, just having linkable directives for lists and tuples would

Thanks everyone for fixing these issues and thanks Shreyan for the bug report.

The main initial is now fixed, so I close the issue.

Let's continue the discussions in remaining open issues:

parallel
* bpo-43960: test_pdb fails when only some tests are run
* bpo-43961 [Windows] test_logging.test_namer_rotator_inheritance() logs a

It took 49 minutes on my Windows 10 VM. Are you sure that you ran the test 
suite sequentially when it was slower?

I advice you run using -j0 option to run tests in parallel: it's much faster, 
and it's also more reliable.

[issue43955] Windows: Running the Python test suite sequentially is interrupted by (Pdb) prompt

[STINNER Victor]

STINNER Victor  added the comment:

I ran "python -m test" on an up to date master branch (commit 
fe52eb62191e640e720d184a9a1a04e965b8a062), there is a single remaining issue. 
test_distutils failed because the deprecation warning was already emited: issue 
fixed by PR 25675. The other issues are gone.

Shreyan Avigyan: "Same errors."

IMO it's a mistake on your side. You ran an outdated version or you didn't 
rebuild Python cleanly.

"FYI test_signal is no longer modifying sys.gettrace thanks to your fix. But 
test_threading still does. (...) I ran the test again and test_signal still 
modifies sys.gettrace()"

It's not my case on my machine, again it sounds like an issue on your side.

I'm no unittest expert, but I have nothing against removing it.

I totally agree to at least remove it from the doc while it does not work.

Dome some 'dumb' testing - and I hope this helps understand why it is failing:

With the the last two func() calls commented out, the function passes:

def test_output_string(self):
stdscr = self.stdscr
encoding = stdscr.encoding
# addstr()/insstr()
for func in [stdscr.addstr, stdscr.insstr]:
with self.subTest(func.__qualname__):
stdscr.move(0, 0)
func('abcd')
func(b'abcd')
s = 'à▒^▒ç▒^▒'
try:
func(s)
except UnicodeEncodeError:
self.assertRaises(UnicodeEncodeError, s.encode, encoding)
func('abcd', curses.A_BOLD)

# func(2, 3, 'abcd', curses.A_BOLD)

[issue43851] Optimise SQLite builds on macOS and Windows

[Berker Peksag]

Berker Peksag  added the comment:

As long as we don't introduce behavior changes between SQLite versions in 
mainstream Linux distributions and macOS/Windows (i.e. an application should 
continue working in Linux, macOS, Windows), it sounds good to me.

Maybe it's worth checking what compile options Debian (and others) are using 
when packaging SQLite.
