[issue45444] test.test_concurrent_futures fail in x86_ 64 architecture

[tongxiaoge]

tongxiaoge  added the comment:

I compared the log and found that  test_socket.HAVE_SOCKET_QIPCRTR is false in 
x86_ 64, and the value is true in the build log on the aarch64 architecture. I 
don't know whether it is related to this value.

[issue45444] test.test_concurrent_futures fail in x86_ 64 architecture

[tongxiaoge]

tongxiaoge  added the comment:

I use the Linux operating system (openeuler), kernel version 4.19.90, GCC 
version 7.3.0. I directly run the following statement in the virtual machine:

1、python3 Lib/test/test_concurrent_futures.py

2、python3 -m test test_concurrent_futures

The test cases are all passed, but I can reproduce the problem in other 
people's container environment. I suspect it is related to the environment 
configuration, but I don't know what it is related to?

Please refer to the attachment for some log information and python3.spec files 
used for build.

[issue45475] gzip fails to read a gzipped file (ValueError: readline of closed file)

[Inada Naoki]

Inada Naoki  added the comment:

>>> ll = [l for l in gzip.GzipFile(filename='data/UTF-8-test_for_gzip.txt.gz')]

This is bad code pattern because you don't close the file explicitly.
Actually, the error caused by the optimization thet iter(GzipFile) returns 
underlaying faster iterator that don't have reference to the GzipFile. So 
GzipFile.__del__ close the file.

Although this is caused by bad code pattern, I must admit this is a regression.
We need to call slow Python function for each lines instead of using fast C 
iterator...

[issue45465] logging messages are needlessly reformatted for every handler

[Vinay Sajip]

Vinay Sajip  added the comment:

Oh, I see what you mean now - I was thinking of the overall message formatted 
using a formatter. However, filters can still change a record's attributes and 
getMessage() could behave differently on different calls because of this. 
Changing things in this area could break existing code.

[issue45395] Frozen stdlib modules are discarded if custom frozen modules added.

[Eric Snow]

Eric Snow  added the comment:

@MAL, who's maintaining Tools/freeze?  I'm not aware of who's using it (other 
than you, of course).  It looks like PyRun isn't compatible with anything newer 
than 3.5, so it seems like that isn't verifying that Tools/freeze still works.  
Neither does it have tests that run in the test suite (nor on buildbots).

So could Tools/freeze have been broken for a while?  I ask because I haven't 
been able to get it work work on the master branch (or on 3.10).

But message formatting is controlled by the record, not by the handler. The

FYI, _xxsubinterpretersmodule is supposed to be an extension module
(not builtin), so it's not meant to use internal APIs.  At some point
that happened and I only noticed now.  I've created bpo-45486 to

It sounds like you're using python 2.7, which is unsupported.

You've not even shown us what line produces the error you're seeing. I don't 
see "type(a[0])" anywhere in the code you posted.

Lacking a way to reproduce this on our own with python 3.x, I'm going to have

When I try it in a few lines, there is no problem. So it is an issue in this 
bigger context with class definitions.
In the few lines type(a[0]) reports ; in the bigger context 
type(a[0]) reports . I have no idea how to reduce this issue in a 
few lines. It must have to do with the use of class in the bigger program, I 
assume. I found a workaround, so it up to you to analyze this further. I have 
only a vary basic knowledge about Python.

[issue45491] help() is too noisy for types used like functions

[Raymond Hettinger]

New submission from Raymond Hettinger :

When someone requests help(range), help(zip), help(property), or 
help(classmethod), the expectation and need is to see something like what is 
shown in main documentation rather than being subjected to a listing of every 
standard dunder method.

It would be nice to have a way to mark types that are mostly used like 
functions so that help() output will be more focused and less noisy.  Then 
help() can omit the Methods and Static methods sections.  It would keep the 
section for non-standard descriptors such as start, stop, step, fget, fset, or 
fdel.

Alternatively, for all types, we can condense the Methods and Static Methods 
sections to just list the standard dunder methods rather that eating several 
rows of output per method.

[issue45427] importlib.readers.MultiplexedPath

[Filipe Laíns]

Filipe Laíns  added the comment:

The Traversable protocol does not guarantee you access to the file-system path. 
pathlib.Path happens to give you that information, but other traversables are 
not required to.

The main reasoning for this is that traversables do not need to exist on the 
file-system, we can be reading from a zip, database, etc.

str(path) does give you the file-system path on pathlib.Path, but there is no 
guarantee about the value of __str__ on other traversables.
My recommendation here would be to use os.fspath[1] instead if you want to try 
getting the file-system path from traversables.

I don't really know what you are trying to accomplish, but I would recommend 
that you try designing your code directly on top of the Traversable interface, 
which should make it work on anything we return in importlib.resources.files.
If you actually need a file-system path, to pass to an external program or 
something like that, you can use the importlib.resources.as_file[2] helper.

bpo-44200 proposes documenting that traversables should implement __fspath__ if 
they represent a file-system path, which could help a bit with your issue.

[issue45490] [meta][C API] Avoid C macro pitfalls and usage of static inline functions

[STINNER Victor]

New submission from STINNER Victor :

C macros are really cool and useful, but there are a bunch of pitfalls which 
are better to avoid:
https://gcc.gnu.org/onlinedocs/cpp/Macro-Pitfalls.html

Some macros of the Python C API have been converted to static inline functions 
over the last years. It went smoothly, I am not aware of any major issue with 
these conversions.

This meta issue tracks other issues related to macros and static inline 
functions.


=== Return void ===

One issue is that some macros are treated as an expression and can be reused, 
whereas it was not intended. For example PyList_SET_ITEM() was implemented as 
(simplified code):

  #define PyList_SET_ITEM(op, i, v) (op->ob_item[i] = v)

This expression has a value! Two projects used this value by mistake, like:

  "if (obj == NULL || PyList_SET_ITEM (l, i, obj) < 0)"

PyList_SET_ITEM() was fixed by casting the expression to void:

  #define PyList_SET_ITEM(op, i, v) ((void)(op->ob_item[i] = v))

=> bpo-30459



=== Abuse macros as an l-value ===

The Py_TYPE() macro could be used to assign a value: "Py_TYPE(obj) = new_type".

The macro was defined as:

  #define Py_TYPE(ob) (ob->ob_type)

It was converted to a static inline function to disallow using it as an l-value 
and a new Py_SET_TYPE(op, new_type) function was added. These changes give more 
freedom to other Python implementations to implement "PyObject" and 
Py_SET_TYPE().

=> bpo-45476 "[C API] Disallow using PyFloat_AS_DOUBLE() as l-value"
=> bpo-39573 PyObject Py_TYPE/Py_SET_TYPE


=== C API: Macros and embedded Python ===

Sadly, only symbols exported by libpython are accessible to other programming 
languages embedding Python. Macros of the Python C API are simply not available 
to them. Projects embedding Python have to hardcode constants and copy macros 
to their own language, with the risk of being outdated when Python macros are 
updated.

Even some projects written in C cannot use macros, because they only use 
libpython symbols. The vim text editor embeds Python this way.

Also, macros are simply excluded from the Python stable ABI (PEP 384).


=== Performance of static inline functions ===

In bpo-45116, it seems like _PyEval_EvalFrameDefault() reached Visual Studio 
thresholds and some static inline functions are no longer inlined 
(Py_INCREF/Py_DECREF).

I also noticed that when Python is built in debug mode in Visual Studio, static 
inline functions are not inlined. Well, the compiler is free to not inline in 
debug mode. I guess that GCC and clang also skip inlining using -Og and/or -O0 
optimization levels. Using __forceinline and __attribute__((always_inline)) on 
static inline functions (Py_INCREF, Py_TYPE) for debug builds was discussed in 
bpo-45094, but the idea was rejected.

On the other side, sometimes it's better to *disable* inlining on purpose to 
reduce the stack memory consumption, using the Py_NO_INLINE macro. See recent 
measurements of the stack memory usage:
https://bugs.python.org/issue45439#msg403768

In GH-28893, I noticed that converting a static inline function 
(PyObject_CallOneArg) to a regular function made it faster. I am not really 
sure, more benchmarks should be run to really what's going on.


=== Advantages of static inline functions ===

* It's possible to put a breakpoint on a static inline functions.

* Debuggers and profilers are able to get the static inline function names from 
the machine line, even with inline functions.

* Parameters and the return value have well defined types.

* Variables have a local scope.

* There is no risk of evaluating an expression multiple times.

* Regular C code. No need to use "\" character to multi-line statement. No need 
for "do { ... } while (0)" and other quicks to workaround preprocessor 
pitfalls. No abuse of (((parenthesis))).

[issue45488] Powershell Commands no Longer Recognised

[The Guy]

New submission from The Guy :

I am using pyinstaller to port my python programs into windows executables so 
that I can distribute them among my friends, and I recently assigned python to 
my windows PATH (I'm still not 100% sure what that means so idk if im even 
saying that right) and now a large amount of my computers basic powershell 
commands are no longer recognized; trying to use the cmd cmdlet i am only met 
with the "not recognized as the name of a cmdlet, function, or operable 
program" error. I've checked the internet pretty extensively and I haven't 
found anything that works, if you know what's going on or have any ideas on how 
to fix it, any help would be greatly appreciated. 
P.S. I am an amateur programmer and I just started dipping my toes into python, 
so I apologize if I don't give enough/correct information, I am still very new 
to this and am happy to answer questions as needed. Also sorry if this is the 
wrong place to ask about these kinds of issues, idk where else to ask. (pls be 
nice im new)

[issue45487] SSLEOFError regression with certain servers in Python 3.10

[Richard]

New submission from Richard :

Starting in Python 3.10, TLS connections to certain servers (e.g. 
websocket-cs.vudu.com:443) are failing when it worked fine on Python 3.9 and 
earlier on the same system.


Minimal working example:

```
#!/usr/bin/env python3

import socket
import ssl

HOST = 'websocket-cs.vudu.com'
PORT = 443

sock = socket.create_connection((HOST, PORT))
ctx = ssl.create_default_context()
ssock = ctx.wrap_socket(sock, server_hostname=HOST)
print("Connection successful")
```


Output:
```

In this case, it has to do with how the docs are generated with Sphinx and the

[issue43139] test_ttk test_compound, test_tk test_type fail with Tk 8.6.11.1

[Terry J. Reedy]

Terry J. Reedy  added the comment:

In Paine's failing color test, the returned tuple is The returned tuple is 
(0x4a48, 0x3c27, 0x8c91) versus (0x4a4a, 0x3c3c, 0x8c91), which is to say, 
nearly correct.  Since the tested call is 
  self._getints(self.tk.call('winfo', 'rgb', self._w, color))
either ._getints is buggy on this particular system (seems very unlikely), or 
root.tk.call is doing something flakey on this particular system (ditto), or 
the result is entirely the responsibility of tcl/tk and the test is too severe, 
testing tk, not our _tkinter/tkinter.

The preceding assert, which passed, is
  self.assertEqual(rgb('#F0F'), (0x, 0x, 0x))
Since the should that the call basically works, is the more detailed test 
needed for testing tkinter?

I looked at the color man page.  It says "When fewer than 16 bits are provided 
for each color, they represent the most significant bits of the color, while 
the lower unfilled bits will be repeatedly replicated from the available higher 
bits. For example, #3a7 is the same as #." This is 4 bits to 16. It 
does not give an example for 8 or 12 to 16 and this might allow some wiggle 
room.

Other text indicates some fuzziness in exact colors. "Tk_AllocColorFromObj 
returns a pointer to an XColor structure; the structure indicates the exact 
intensities of the allocated color (which may differ slightly from those 
requested, depending on the limitations of the screen)"  Perhaps this 
screen-specific behavior is happening here. 

Also, "They allow colors to be shared whenever possible, so that colormap space 
is preserved, and they pick closest available colors when colormap space is 
exhausted. "  Could this happen here?

test_winfo_rgb has multiple asserts.  If this one is commented out, do the rest 
pass?

[issue45486] Stop using internal APIs in _xxsubinterpretersmodule.c.

[Eric Snow]

New submission from Eric Snow :

By design, _xxsubinterpretersmodule is not supposed to be a builtin module.  As 
a regular extension module it should only use public (or 
private-but-not-internal) APIs.  In fact, I was careful to not use any internal 
APIs in the implementation.  However, some have crept in.  The usage of 
internal API should be replaced with public (or private) API.  If necessary, 
new API should be added.

[issue45473] Enum: add "name" and "value" keywords to call syntax

[Ethan Furman]

Ethan Furman  added the comment:

> Are there any other names that you would contemplate besides `from_name` and
> `from_value`?

No.

> My reading of your response indicates that you are fundamentally opposed to
> the addition of class methods, since they would limit the space of possible
> instance methods/members.  Is that a fair reading?

Yes.

Instance methods/attributes are not an issue, though, as the instance namespace 
and the class namespace are distinct -- which is why we can have a `value` 
member even though each member has a `value` attribute.

The issue is that class methods/attributes and members (which look like 
attributes) all live in the class namespace, so we cannot have both a 
`from_value` member and a `from_value` class method in the class namespace.

> Do you agree with the fundamental issue that is identified: that the

Only partially.  Being able to easily tell the difference between round and 
square brackets is an important skill to have.  With enums, square brackets are 
akin to dictionary lookup, which uses (string) keys, and the keys of an enum 
are the member names; that leaves round brackets (parenthesis), which is call 
syntax, for value lookup.

Additionally, if the wrong syntax is used then an exception will be raised at 
that location, making it an easy  fix.

This idea has come up before.  I'll look into it.

[issue32596] Lazy import concurrent.futures.process and thread

[Serhiy Storchaka]

Serhiy Storchaka  added the comment:

Thank you Inada-san. My first intention when I seen this code was to simplify 
it, but then I have found that it was an intentional change.

It may be easy to detect such code and raise a syntax warning or error. Or get 
rid of this limitation and allow globals officially here.

[issue45483] pure Python class that has been registered as a `collections.abc.Sequence` can't be recgnized by the match statement without the `_abc` module

[GalaxySnail]

New submission from GalaxySnail :

Pure Python class that has been registered as a `collections.abc.Sequence` 
can't be recgnized by the match statement without the `_abc` module.

For example:

```
>>> from test.support.import_helper import import_fresh_module

>>> collections_abc_with_c_abc = import_fresh_module(
... "collections.abc", fresh=["_collections_abc", "abc", "_abc"])

>>> class MyList:
... def __init__(self, iterable):
... self.list = list(iterable)
... def __len__(self):
... return len(self.list)
... def __getitem__(self, item):
... return self.list[item]
...
>>> collections_abc_with_c_abc.Sequence.register(MyList)

>>> match MyList(range(3, 10)):
... case [x, *_]:
... print(x)
... case _:
... print("not a sequence")
...
3

>>> collections_abc_with_py_abc = import_fresh_module(
... "collections.abc", fresh=["_collections_abc", "abc"], blocked=["_abc"])
>>> class MyList:
... def __init__(self, iterable):
... self.list = list(iterable)
... def __len__(self):
... return len(self.list)
... def __getitem__(self, item):
... return self.list[item]
...
>>> collections_abc_with_py_abc.Sequence.register(MyList)

>>> match MyList(range(3, 10)):
... case [x, *_]:
... print(x)
... case _:
... print("not a sequence")
...
not a sequence
```

It seems to be caused by 
https://github.com/python/cpython/commit/069e81ab3da46c441335ca762c4333b7bd91861d
 , only `tp_flags` are checked in the `MATCH_SEQUENCE` opcode. `Mapping` has 
the same problem.

[issue43139] test_ttk test_compound, test_tk test_type fail with Tk 8.6.11.1

[E. Paine]

E. Paine  added the comment:

TL;DR I believe these are both Tk issues. I will take it up with them when I 
have time.

Starting with `test_winfo_rgb`, it is not the case that the expected behaviour 
is no longer that #4a3c8c is equivalent to #4a4a3c3c8c8c since this is 
documented on the man page (https://www.tcl.tk/man/tcl/TkLib/GetColor.html#M8). 
I need to do more research into exactly what versions / platforms are effected.

I also believe the problem with `test_configure_type` is on the Tk end, since 
`[menu .m] configure -type {}` succeeds despite not being documented on the man 
page (https://www.tcl.tk/man/tcl8.4/TkCmd/menu.html#M13) nor in the "bad type" 
message:
% [menu .m] configure -type a 
bad type "a": must be normal, tearoff, or menubar

You'd have to create a frozen binary using the standard way freeze
works. I have never run those tests, so don't know whether they work,
but, of course, made sure that the freeze works as basis for PyRun
and patched it slightly to add features we needed.

One of these days, I need to refactor PyRun into a standalone project
and put it on Github (it's currently integrated into our internal
single repo setup). Then it'll be easier to see the changes I made.
For now, I can only reference the tar file:

https://www.egenix.com/products/python/PyRun/#Download
https://www.egenix.com/products/python/PyRun/#Installation

I can send you an updated version for Python 3.8, if there's
interest.

Essentially, you need to create a Python module which runs your
application, then point freeze.py to it and then compile the
generated .c files using the generated Makefile.

[issue45476] [C API] Convert "AS" functions, like PyFloat_AS_DOUBLE(), to static inline functions

[Gareth Rees]

Gareth Rees  added the comment:

If the problem is accidental use of the result of PyFloat_AS_DOUBLE() as an 
lvalue, why not use the comma operator to ensure that the result is an rvalue?

The C99 standard says "A comma operator does not yield an lvalue" in §6.5.17; I 
imagine there is similar text in other versions of the standard.

The idea would be to define a helper macro like this:

/* As expr, but can only be used as an rvalue. */
#define Py_RVALUE(expr) ((void)0, (expr))

and then use the helper where needed, for example:

#define PyFloat_AS_DOUBLE(op) Py_RVALUE(((PyFloatObject *)(op))->ob_fval)

Inlining is something that is completely under the control of the
used compilers. Compilers are free to not inline function marked for
inlining, which can result in significant slowdowns on platforms
which are e.g. restricted in RAM and thus emphasize on small code size,
or where the CPUs have small caches or not enough registers (think
micro-controllers).

The reason why we have those macros is because we want the developers to be
able to make a conscious decision "please inline this code unconditionally
and regardless of platform or compiler". The developer will know better
what to do than the compiler.

If the developer wants to pass control over to the compiler s/he can use
the corresponding C function, which is usually available (and then, in many
cases, also provides error handling).

Perhaps, but then I never had to profile macro use in the past. Instead,
what I typically found was that using macros results in faster code when
used in inner loops, so profiling usually guided me to use macros instead
of functions.

That said, the macros you have inlined so far were all really trivial,
so a compiler will most likely always inline them (the number of machine
code instructions for the call would be more than needed for
the actual operation).

Perhaps we ought to have a threshold for making such decisions, e.g.
number of machine code instructions generated for the macro or so, to
not get into discussions every time :-)

A blanket "static inline" is always better than a macro is not good
enough as an argument, though.

Esp. in PGO driven optimizations the compiler could opt for using
the function call rather than inlining if it finds that the code
in question is not used much and it needs to save space to have
loops fit into CPU caches.
