[issue42257] platform.libc_ver() doesn't consider in case of executable is empty string

[Kurochan]

New submission from Kurochan :

Currently, `platform.libc_ver()` doesn't consider in case of `executable` 
variable is an empty string.
However, with Python 3.8, the following code could pass an empty string 
`executable` to the `platform.libc_ver()` function.

https://github.com/python/cpython/blob/efc782d29e229924076ffb6645a72f26242fb3ef/Lib/platform.py#L1205
https://docs.python.org/3/library/sys.html#sys.executable

Because the `sys.executable` could return an empty string, so I would like to 
add the empty string handler.

https://github.com/python/cpython/blob/efc782d29e229924076ffb6645a72f26242fb3ef/Lib/platform.py#L174

Or please also merge the following PR to Python 3.8.

I see the documentation mentions it now (in the second gray box here:

and it also suggests to use a shared queue if this is an issue. 


Any objections to closing this issue?

[issue42252] Embeddable Python indicates that it uses PYTHONPATH

[Tom Kent]

Tom Kent  added the comment:

A couple things...

>> One possible use-case is to package it along with another program to use the 
>> interpreter.

> This is the primary use case. If you're doing something else with it, you're 
> probably misusing it :)

Interesting, I'd been expecting this was commonly used as the way to give 
access to python3X.dll. We actually do (or are trying to do) both from our 
installation.



I've been mostly focusing on `PYTHONPATH` because that's where I encountered 
the issue. Which if any of the other env variables are respected? 



Would there be an argument to add additional command line options that could be 
used as a more secure alternative to the env variables? A command line argument 
`-e` that is the opposite of `-E` and enables the usage of PYTHON* env? Maybe 
this doesn't make sense since you said it is the ._pth that causes this...just 
thinking aloud.

The two options you mention (modify ._pth and append to sys.path) aren't great 
because we 1) would prefer to use the un-modified python distro 2) don't own 
the scripts that we are embedding, they are from a 3rd party so modifications 
are complicated.

[issue42252] Embeddable Python indicates that it uses PYTHONPATH

[Steve Dower]

Steve Dower  added the comment:

Updating the documentation link on the download page is being discussed as we 
speak.

> interpreter.

This is the primary use case. If you're doing something else with it, you're 
probably misusing it :)

> In this case, the user may assume that adding something to the `PYTHONPATH` 
> env variable, as most of the launching methods allow, would take hold.

Agreed. The documentation explains this, though likely doesn't make clear 
enough that it's the presence of the ._pth file that triggers the behaviour.

> ... then promptly look at python --help when that fails. 

I'm pretty sure the help text is generated before we've tried to detect any 
local configuration, so it's far from trivial to make it dynamic based on 
context. 

> Maybe a better question is why should the embeddable distribution's 
> python.exe ignore env variables? Wouldn't it make more sense to depend on the 
> user to add a `-E` if that is what they desire?

It's to make it non-exploitable by default. The theory being that it will 
likely be installed into Program Files by an admin, which means file-based 
configuration is locked down from regular users and an attacker can't rely on a 
fully functioning Python runtime being present. 
 Most people wildly underestimate how exploitable CPython is via environment 
variables.

In an embedded scenario, you also have other ways to update paths, either 
statically (in the ._pth file) or in Python code (via sys.path modification). 
And you can of course delete the ._pth file if you don't feel you need the 
isolation, but there are legitimate reasons we don't recommend that one.

Not enough of this is documented that well, unfortunately. It sounds like we 
should:
* add a note to the environment variables section of --help that some other 
options may disable these
* add a link to https://docs.python.org/3/using/windows.html#windows-embeddable 
back to the download page (it was removed in the 3.9 releases for some reason)
* expand that doc section to link forward to 
https://docs.python.org/3/using/windows.html#finding-modules and maybe 
rearrange for making it more obvious how to use this package

Some work has been done this year on expanding support for these types of 
glyphs in Tk, but I'm not sure of its current state--it's not my area of 
expertise. Can you open a ticket at https://core.tcl-lang.org/tk/ so one of the 
folks working on this can take a look?

[issue41618] [C API] How many slots of static types should be exposed in PyType_GetSlot()

[Petr Viktorin]

Petr Viktorin  added the comment:

> Can we write those info to docs? In case some developer want to exposing slot 
> in future.

Do you mean something like "only expose a slot if you have a reason for 
exposing it"? That sounds like a tautology.
Where in the docs would this go?

> nb_inserved in PyNumberMethods should be removed?

You mean nb_reserved, right?
It can't be removed; old-style initialization is positional.
But it could be replaced according to PEP387:
- in 3.x, raise a warning if it is not set to NULL (in static types)
- in 3.x+2, throw an error if it is not set to NULL (in static types)
- in 3.x+3 or later, it can be replaced by another slot, if there's something 
we need to add to PyNumberMethods

[issue41832] PyType_FromSpec() should accept tp_doc=NULL

[Petr Viktorin]

Petr Viktorin  added the comment:

The PyType_Slot documentation says that the pointer may not be NULL: 
https://docs.python.org/3/c-api/type.html?highlight=pytype_fromspec#c.PyType_Slot.PyType_Slot.pfunc

If you change this, why do it only for tp_doc, but for all the slots? NULL 
should *always* mean that the slot is set to NULL instead of inherited. (Except 
maybe in cases where this is dangerous; then it should result in an error?)
See: https://bugs.python.org/issue26979

If you want to only change this for tp_doc, please also update the PyType_Slot 
documentation to cover the exception.

[issue42256] BaseCookie.__parse_string() doesn't work with expires= between cookies

[Paulie Pena]

New submission from Paulie Pena :

Since `requests` creates a comma-separated list for any duplicated headers, 
this causes a problem when `expires=...` is between two `Set-Cookie` header 
values. `BaseCookie.__parse_string()` in 
https://github.com/python/cpython/blob/master/Lib/http/cookies.py, in that 
case, will just give up, since it thinks it was given an invalid cookie. The 
fix is to replace the comma at the end of each trailing `expires=...` with a 
semicolon. Inside `BaseCookie.__parse_string()`, before the `while` loop, all 
that should be needed is to add this:
```
str = re.sub('(=\w{3},\s[\w\d\s-]{9,11}\s[\d:]{8}\sGMT),', r'\1;', str)
```

[issue42252] Embeddable Python indicates that it uses PYTHONPATH

[Tom Kent]

Tom Kent  added the comment:

I'm not sure I agree with that. One possible use-case is to package it along 
with another program to use the interpreter. In this case they could use the 
other program's native language features (e.g. .Net's Process.Start(), Win32 
API's CreateProcess(), Even Python's subprocess but why?, etc) to run 
`python.exe myscript.py`. 

In this case, the user may assume that adding something to the `PYTHONPATH` env 
variable, as most of the launching methods allow, would take hold. When this 
fails, the first attempt at debugging would be to try it interactively with the 
same command, then promptly look at python --help when that fails. 

Maybe a better question is why should the embeddable distribution's python.exe 
ignore env variables? Wouldn't it make more sense to depend on the user to add 
a `-E` if that is what they desire?

[issue42225] Tkinter hangs or crashes when displaying astral chars

[STINNER Victor]

STINNER Victor  added the comment:

The following program fails with:
---
X Error of failed request:  BadLength (poly request too large or internal Xlib 
length error)
  Major opcode of failed request:  138 (RENDER)
  Minor opcode of failed request:  20 (RenderAddGlyphs)
  Serial number of failed request:  4248
  Current serial number in output stream:  4956
---

Python program:
---
from tkinter import Tk
from tkinter.scrolledtext import ScrolledText
root = Tk()
text = ScrolledText(root, width=80, height=40)
text.pack()

for i in range(0x1, 0x4, 32):
chars = ''.join(chr(i+j) for j in range(32))
text.insert('insert', f"{hex(i)} {chars}\n")

input("Press enter to exit")
---

It seems like the first character which triggers this RenderAddGlyphs BadLength 
issue is: U+1f6c2. See attached emoji.png screenshot. As you can see, some 
emojis are rendered in color in Gnome Terminal. I guess that it uses the Gtk 3 
pango library to render these characters.

[issue42252] Embeddable Python indicates that it uses PYTHONPATH

[Eryk Sun]

Eryk Sun  added the comment:

The embeddable distribution isn't intended for end users to run Python scripts 
from the command line, so I don't think the CLI help needs to be special cased. 
The documentation you quoted should be clarified as something like "isolated 
from user and system Python settings, including environment variables such as 
PYTHONPATH, registry settings, and installed packages". It would be helpful as 
well if the Windows download links on python.org explained or linked to the 
intended use case for the embeddable distribution. Sometimes people mistakenly 
download it when they really need a normal Python installation.

[STINNER Victor]

STINNER Victor  added the comment:

In PR 23131, I added a comment to _PyInterpreter_Clear() to remind me that 
trying to destroy a Python type after the last GC collection doesn't work as 
expected:

// All Python types must be destroyed before the last GC collection. Python
// types create a reference cycle to themselves in their in their
// PyTypeObject.tp_mro member (the tuple contains the type).

Gotcha. I am pretty sure that this will have a similar problem as the coverage 
people were claiming when we were not properly removing all dead code (slightly 
less coverage percentage). This is not a problem of course, but we should ping 
the coverage folks so they are aware of this.

[issue42252] Embeddable Python indicates that it uses PYTHONPATH

[Tom Kent]

New submission from Tom Kent :

According to the documentation 
https://docs.python.org/3/using/windows.html#windows-embeddable

> When extracted, the embedded distribution is (almost) fully isolated 
> from the user’s system, including environment variables, system registry 
> settings, and installed packages

The embedded distribution should ignore the environment variables. 

This is echoed in this prior issue that thought `PYTHONPATH` not being 
respected was a bug:
https://bugs.python.org/issue28245

Regardless of the decision to respect environment variables, the message that 
is displayed when running the distribution's `python --help` needs to indicate 
how it will act. 

Currently, for the embedded distribution, which doesn't respect the env 
variables, there is a section in the output from running `python -help` that 
indicates:

```
Other environment variables:
PYTHONSTARTUP: file executed on interactive startup (no default)
PYTHONPATH   : ';'-separated list of directories prefixed to the
   default module search path.  The result is sys.path.
PYTHONHOME   : alternate  directory (or ;).
   The default module search path uses 
\python{major}{minor}.
PYTHONPLATLIBDIR : override sys.platlibdir.
PYTHONCASEOK : ignore case in 'import' statements (Windows).
PYTHONUTF8: if set to 1, enable the UTF-8 mode.
PYTHONIOENCODING: Encoding[:errors] used for stdin/stdout/stderr.
PYTHONFAULTHANDLER: dump the Python traceback on fatal errors.
PYTHONHASHSEED: if this variable is set to 'random', a random value is used
   to seed the hashes of str and bytes objects.  It can also be set to an
   integer in the range [0,4294967295] to get hash values with a
   predictable seed.
PYTHONMALLOC: set the Python memory allocators and/or install debug hooks
   on Python memory allocators. Use PYTHONMALLOC=debug to install debug
   hooks.
PYTHONCOERCECLOCALE: if this variable is set to 0, it disables the locale
   coercion behavior. Use PYTHONCOERCECLOCALE=warn to request display of
   locale coercion and locale compatibility warnings on stderr.
PYTHONBREAKPOINT: if this variable is set to 0, it disables the default
   debugger. It can be set to the callable of your debugger of choice.
PYTHONDEVMODE: enable the development mode.
PYTHONPYCACHEPREFIX: root directory for bytecode cache (pyc) files.
```

This may lead users (it did lead this one) to assume that they are doing 
something wrong when for example the output of `sys.path` doesn't included 
items in `os.environ["PYTHONPATH"]`. 

Realizing that it may be difficult to achieve, the help output should match the 
state of what the interpreter will actually do if run.

[issue42251] Add threading.gettrace and threading.getprofile

[Mario Corchero]

New submission from Mario Corchero :

When working in a C extension from a non-python created thread which calls 
PyGILState_Ensure as it later calls a Python callback on user code, I wished 
there was a way to set the trace function similar to what a native Python 
thread would do.

We could just call sys.gettrace within the thread, but the application might 
have chosen to set threading.settrace differently.

Same applies for threading.setprofile.

[issue41796] _ast module state should be made per interpreter

[STINNER Victor]

STINNER Victor  added the comment:

There is a leak (I just marked bpo-42250 as duplicate of this issue):

https://buildbot.python.org/all/#/builders/205/builds/83

OK
..
test_ast leaked [23640, 23636, 23640] references, sum=70916
test_ast leaked [7932, 7930, 7932] memory blocks, sum=23794
1 test failed again:
test_ast

test_subinterpreter() test leaks.

There are two problems:

* _PyAST_Fini() is only called in the main interpreter, I forgot to remove the 
"if _Py_IsMainInterpreter()"
* _PyAST_Fini() is called after the last GC collection, whereas AST_type 
contains a reference to itself (as any Python type) in its tp_mro member. A GC 
collection is required to destroy the type. _PyAST_Fini() must be called before 
the last GC collection.

[issue42246] Implement PEP 626

[Mark Shannon]

Mark Shannon  added the comment:

The following code is completely eliminated by the macros.

1. if 0:
2. secret_debugging_code()

PEP 626 says that all executed lines of code must generate trace events,
so we need to emit an instruction for line 1.

Dead code elimination will remove the `secret_debugging_code()`, but leave the 
test. The peephole optimiser can then reduce it to a NOP, but won't eliminate 
it as it is the only instruction for line 1.
