[issue30082] hide command prompt when using subprocess.Popen with shell=False on Windows

[Eryk Sun]

Eryk Sun  added the comment:

If only force_hide is implemented, based on `wShowWindow=SW_HIDE`, please 
ensure that it's clearly documented that this option hides the main window 
(i.e. first top-level window) of any application that doesn't bypass the 
default behavior of the window manager.

This means a script can't simply use `force_hide=True` universally when running 
arbitrary commands, since hiding the main window of a GUI app is probably 
undesired behavior. If it's unknown in advance whether an executable is a 
console or GUI app, it can be determined via SHGetFileInfoW(). For example:

import ctypes
shell32 = ctypes.WinDLL('shell32', use_last_error=True)
SHGFI_EXETYPE = 0x2000

def is_gui_exe(path):
result = shell32.SHGetFileInfoW(path, 0, None, 0, SHGFI_EXETYPE)
# the high word is non-zero for a GUI app
return (result >> 16) > 0

>>> is_gui_exe(r'C:\Windows\pyw.exe')
True
>>> is_gui_exe(r'C:\Windows\py.exe')
False

Regarding the effect of wShowWindow:

If the STARTUPINFO record defines wShowWindow, the value gets used as the 
normal show command for the first top-level window that's shown in the process. 
In particular, it overrides the first use (and only the first use) of the 
commands SW_SHOW, SW_SHOWNORMAL, and SW_SHOWDEFAULT (yes, only the first use of 
the latter; the documentation is wrong). This affects showing the first 
top-level window regardless of whether it's explicit via ShowWindow() or 
implicit via the WS_VISIBLE window style. For the latter, the implicit command 
is SW_SHOW, which one can override in the CreateWindowW() call by passing 
x=CW_USEDEFAULT and y as the show command to use. 

To completely ignore the STARTUPINFO wShowWindow value for the main window, an 
application can use an initial show command that wShowWindow doesn't override, 
such as SW_HIDE, SW_RESTORE (behaves like SW_SHOWNORMAL on first use), 
SW_MINIMIZE, or SW_MAXIMIZE. For example, for the first command use 
ShowWindow(hwnd, SW_HIDE). Subsequently calling ShowWindow(hwnd, SW_SHOWNORMAL) 
will show the window normally (i.e. active and restored) instead of using the 
STARTUPINFO wShowWindow command.

[issue45347] datetime subject to rounding?

[Daniele Varrazzo]

Daniele Varrazzo  added the comment:

Considering that I have found another pair of dates failing equality, and they 
are too on the last Sunday of October, the hypothesis of rounding in timezone 
code starts to look likely

Python 3.7.9 (default, Jan 12 2021, 17:26:22) 
[GCC 8.3.0] on linux

>>> import datetime, backports.zoneinfo
>>> d1 = datetime.datetime(2255, 10, 28, 7, 31, 21, 393428, 
>>> tzinfo=datetime.timezone(datetime.timedelta(seconds=27060)))
>>> d2 = datetime.datetime(2255, 10, 28, 2, 0, 21, 393428, 
>>> tzinfo=backports.zoneinfo.ZoneInfo(key='Europe/Rome'))
>>> d1 - d2
datetime.timedelta(0)
>>> d1 == d2
False

Added Python 3.7 to the affected list.

[issue45645] Deep recursion terminates script execution with no error (Windows, Python 3.9)

[Steve Dower]

Steve Dower  added the comment:

> But why does it happen only on Windows?

Because it's the operating system that is terminating the process :) 
Other operating systems behave differently when you exceed the stack, 
and may also allocate different amounts of stack space, making it less 
likely that you hit it.

The behavior has been addressed in the fix for bpo-45395.  However, I'd like to 
change the name of the -X option from "frozen_modules" to "frozen_stdlib", to 
avoid any confusion in the future.  After that this issue is done.

[issue45645] Deep recursion terminates script execution with no error (Windows, Python 3.9)

[Steve Dower]

Steve Dower  added the comment:

This is almost certainly because of how Windows handles stack overflow 
exceptions, and the fact that there's no way for us to detect it reliably.

There's some work going on to reduce the C stack depth when calling heavily 
nested Python code (see issue45256), but there's nothing else we can really do 
I'm afraid.

I'm marking *this* issue as wontfix, but hopefully we can make some improvement 
on this general issue through other issues. Thanks for reporting it!

[issue30082] hide command prompt when using subprocess.Popen with shell=False on Windows

[Steve Dower]

Steve Dower  added the comment:

I'd rather only have one force_hide option that does its best to hide 
everything.

Yes, it's probably unintuitive for GUI apps, it might even be maliciously 
misused, but it does have occasional legitimate uses. And besides, an app can 
easily ignore SW_HIDE if it wants.

Bear in mind that the test suite should (mostly) operate without ctypes. So if 
you use ctypes to verify the test, make it a separate test that skips if ctypes 
cannot be imported, and have a test that runs it without verifying the window 
is actually hidden. That way we always at least _run_ the code, even if we only 
(usually) verify that it's actually hiding the window.

[issue45653] Freeze the encodings module.

It works as long as __path__ is set properly, which it is now.  FWIW,
I tested freezing only some of the submodules a while back and it
worked fine.  That was using a different branch that I never merged
but it should be fine with the different change that got merged.  Of
course, we'd need to verify that if we went that route.

[issue45661] [meta] Freeze commonly used stdlib modules.

[Eric Snow]

Eric Snow  added the comment:

One to consider that isn't necessarily used that commonly is sysconfig.  
However, that could also involve freezing the "sysconfigdata" file (without 
needing to expose it as a module).

[issue43656] TracebackException or StackSummary.extract with capture_locals=True fail to catch exceptions raised by repr() on value of frame local variable in FrameSummary.__init__.

[Martin]

Martin  added the comment:

Once again a very good summary, thanks Joe!

> it would be quite useful if this function parameter was given not just the 
> local variable values, but also the name of the local variable and maybe also 
> the stack frame it is in

So this would be something like `format_locals(filename, lineno, name, locals) 
-> dict[str,str]` that could be used inside FrameSummary.__init__. I like that!

I wouldn't bother with detecting un-repr-able objects in Python itself, but if 
the above `format_locals` was implemented, you could easily prepare such a 
formatter for your students that hides `self` et al. and/or catch exceptions 
during `repr` to your liking.

What is needed to get an OK for such a change?

[issue45661] [meta] Freeze commonly used stdlib modules.

[Eric Snow]

New submission from Eric Snow :

We're already freezing modules needed for bootstrapping the runtime, as well as 
the modules imported during startup. [1][2]  We're also planning on freezing 
argparse. [3]  There may be other modules (or files) worth freezing (assuming 
we don't just freeze the entire stdlib, which would have some potential 
downsides).

This issue is meant to cover the broader idea.  The work to actually freeze 
modules should be handled in separate issues.

[issue21736] Add __file__ attribute to frozen modules

[Eric Snow]

Eric Snow  added the comment:

I've opened the following issues related to frozen stdlib modules:

https://bugs.python.org/issue45652
https://bugs.python.org/issue45658
https://bugs.python.org/issue45659

Again, I'm leaving this issue open to deal with the broader question of frozen 
modules outside the stdlib, where the solution isn't so obvious.  The question 
of targeting the FileLoader (or SourceLoader) ABC should probably be handled 
separately.  (Note that bpo-45020 has some related discussion.)

I had already listed some of those details.

[issue45659] Add FrozenImporter.get_filename().

[Eric Snow]

Eric Snow  added the comment:

Note that there isn't any intent currently to implement the FileLoader ABC [1], 
which would require having FrozenImporter instances, adding the "name" and 
"path" attributes to them, as well as the get_data() method.  The same goes for 
the SourceLoader ABC. [2]

Again, frozen modules don't have files but instead were only derived from files 
during the build process.  For frozen stdlib modules we happen to know where to 
find the corresponding source files.

[issue45659] Add FrozenImporter.get_filename().

[Eric Snow]

New submission from Eric Snow :

Now that __file__ is set on frozen (stdlib) modules, we can add an 
implementation for FrozenImporter.get_filename().  This would make 
FrozenImporter and implementation of ExecutionLoader. [1]

There is a caveat: in spec_from_loader() [2] we infer the presence of 
get_filename() to mean the loader is file-based, which FrozenImporter isn't. 
 In that case we call spec_from_file_location() [3], which should not be used 
for frozen modules.  Most importantly, spec.origin for frozen modules should 
remain "frozen", spec.cached should remain None, and spec.has_location should 
remain False.  That's because the module was imported frozen and not from a 
file (even though it originated in a file).

[issue45657] Enum behavior when values are functions

[Alex Waygood]

Alex Waygood  added the comment:

It would be difficult to define methods in Enum classes if functions in the 
class namespace were automatically converted into members. You can get around 
this by wrapping your functions in `functools.partial` objects; see 
https://stackoverflow.com/questions/40338652/how-to-define-enum-values-that-are-functions.
