[issue44828] tkinter.filedialog linked with Tk 8.6.11 crashes on macOS 12 Monterey, breaking IDLE saves

I'm pretty sure that's a documented feature. Any code compiled with a 10.15 or 
earlier SDK will never see version 11.0 or later when using regular in process 
APIs (and IIRC that includes usage of @available/__builtin_available)

[issue45708] PEP 515-style formatting with underscores does not seem to work for Decimal

[Sander Bollen]

New submission from Sander Bollen :

Hello,

It appears that Decimal does not support PEP-515 style formatting with 
underscores as thousands separators. 

```
>>> from decimal import Decimal
>>> f"{Decimal('5000'):,}"
'5,000'
>>> f"{Decimal('5000'):_}"
Traceback (most recent call last):
  File "", line 1, in 
ValueError: invalid format string

```

This does work for all the other types mentioned in PEP515

```
>>> f"{5000:_}"
'5_000'
>>> f"{5000.0:_}"
'5_000.0'
>>> f"{complex(5000, 1):_}"
'(5_000+1j)'
```

I have tried this on python 3.8, 3.9 and 3.10 on a Mac.

[issue45709] 3.11 regression: tracing with-statement on exit from block

[Ned Batchelder]

New submission from Ned Batchelder :

Python 3.11 seems to have reverted a behavior that was new in 3.10.0b1: exiting 
a with-statement re-visits the with line on the way out.

--- %<  bug2.py --

def trace(frame, event, arg):
# The weird globals here is to avoid a NameError on shutdown...
if frame.f_code.co_filename == globals().get("__file__"):
lineno = frame.f_lineno
print("{} {}: {}".format(event[:4], lineno, linecache.getline(__file__, 
lineno).rstrip()))
return trace

print(sys.version)
sys.settrace(trace)

import contextlib

Running with 3.10 shows re-visiting the with:

Is this a bug in 3.11, or an intentional return to previous behavior?

(BTW: there is no 3.11regression keyword available)

[issue45672] Mutation tests results of typing.py

[Oleg Iarygin]

Oleg Iarygin  added the comment:

> What is the problem actually?

I guess, Lib/test/test_typing.py has gaps in test coverage. The report provided 
by the OP is a list of random modifications that corrupt logic of Lib/typing.py 
but still pass all test cases.

Mutation testing is validation of tests themselves. A mutation framework takes 
code that the validated test actually tests, makes some random but 
syntactically correct change, and runs the test that should fail some assertion 
here. If so, the code is rolled back and another mutation attempt is done. If 
the validated test catches all thousands of such attempts, we can consider it a 
reliable safety net for any refactoring. Otherwise, we open the report and 
start to supplement tests and probably package documentation to cover missed 
scenarios.

Actually, something like cosmic-ray may be added into a CI pipeline, but I 
suspect that preliminary fixing of test coverage will be a task of the OP 
themselves. There are no people with enough free time to sit down and sort all 
tests out, being overwhelmed with new language features, bug fixing and already 
pending epics of, for example, closing Python internals from extension modules 
to stop constantly breaking backward compatibility, or fixing startup modules 
to properly freeze them for speedup of Python launching.

[issue45672] Mutation tests results of typing.py

[Serhiy Storchaka]

Serhiy Storchaka  added the comment:

The tests are passed because this modification does not affect behavior, it 
just makes the code slightly less efficient. Replacing i+1 with i just adds one 
iteration:

b = bases[i]  # == self
if isinstance(b, _BaseGenericAlias) and b is not self:
return ()

Since b is self, the condition is always false.

It is impossible to catch this change in tests because both codes are 
equivalent.

[issue45710] Junction/symbolic folder access error on Windows 11

[Fabio Storino]

New submission from Fabio Storino :

After upgrading to Windows 11 I can't run Python scripts from a junction folder 
anymore. Everything else works as before on that folder.

Background: I have Minecraft installed on a second volume (E:\Games\Minecraft). 
I created a junction folder at %appdata%\.minecraft pointing to that folder. 
When I try to run a Python script from that folder I get this error:

---
python: can't open file 'C:\Users\x\AppData\Roaming\.minecraft\test.py': 
[Errno 22] Invalid argument
---

When trying to debug in VS Code, I get a more detailed error:

---
Traceback (most recent call last):
  File "C:\Program 
Files\WindowsApps\PythonSoftwareFoundation.Python.3.9_3.9.2032.0_x64
__qbz5n2kfra8p0\lib\ntpath.py", line 647, in realpath
path = _getfinalpathname(path)
OSError: [WinError 649] The create operation failed because the name
contained at least one mount point which resolves to a volume to
which the specified device object is not attached:
'c:\\Users\\x\\AppData\\Roaming\\.minecraft'
---

When trying to open that junction folder in Python's IDLE I get the following 
error message:

---
[Window Title] Location is not available

[Content] C:\Users\x\AppData\Roaming\.minecraft is not accessible.

The create operation failed because the name contained at least one
mount point which resolves to a volume to which the specified device
object is not attached.
---

I tried creating a symbolic directory link instead of a junction, but got the 
same message.

I can run the same scripts directly from the target folder (E:\Games\Minecraft).

I can also run them from the junction folder from an Ubuntu terminal on WSL2 
(Windows Subsystem for Linux).

I tried this with Python 3.9 and 3.10 (WSL2 uses Python 3.8).

this is a test utility, it doesn't need to verify input types.

[issue45711] Simplify the interpreter's (type, val, tb) exception representation

[Irit Katriel]

New submission from Irit Katriel :

Exceptions are represented in the interpreter as (type, val, tb) triplets which 
most of the time contain redundant information (the type is the type of val and 
the tb is also on the exception). This complicates the code and is inefficient 
as opcodes that manage exceptions push and pop 3 items for each exception. 

We will change the internal representation to be (1) just the exception value 
if it is normalised and (2) a tuple of the 3 values for the uncommon case where 
they are all needed.

[issue45672] Mutation tests results of typing.py

[Oleg Iarygin]

Oleg Iarygin  added the comment:

> because this modification does not affect behavior

Unfortunately, this one (that I missed by not reading the report thoroughly) 
makes the framework totally unsuitable for CI.

However, looking at such false positives allows to muse about reasons behind 
design choises. For example (in a snippet you cited), why Python runtime stores 
bases as a tuple, not as a linked list. Anyway, application of the method 
resolution order scans them sequentially, they are not of a primitive type (so 
tuples give no optimization), a call of bases.index() may be replaced with a 
reference property inside class internals, etc.

Though, I perfectly understand that such treatment leads to immense amount of 
refactoring with no performance gain, probably counterweighted with removal of 
couple of internal packages that will become unused after it. That's why I 
wrote about "a task of the OP themselves".

[issue45708] PEP 515-style formatting with underscores does not seem to work for Decimal

[Mark Dickinson]

Mark Dickinson  added the comment:

I think the two main reasons that applied to not implementing the parsing part 
of PEP 515 for the Decimal type (speed, compliance with the IBM specification) 
don't apply to the formatting side.

We do need to think about the implications of making local changes to our copy 
of the externally-maintained libmpdec library, though.

Changing Python versions: this is a new feature, so could only go into Python 
3.11.

[issue27863] multiple issues in _elementtree module

[Ahmed Sayeed]

Ahmed Sayeed  added the comment:

amd64-linux-siginfo.c: Adjust include order to avoid gnulib error 
http://www.compilatori.com/computers/latest-car-deals/
On Fedora rawhide, after updating to glibc-2.33, I'm seeing the
following build failure:
http://www.acpirateradio.co.uk/travel/good/
  CXXnat/amd64-linux-siginfo.o
In file included from /usr/include/bits/sigstksz.h:24, 
http://www.logoarts.co.uk/services/affordable-printer/ 
 from /usr/include/signal.h:315,
 from ../gnulib/import/signal.h:52,

first."
  663 |  #error "Please include config.h first." 
http://connstr.net/property/mars-researches/ 
  |   ^

glibc-2.33 has changed signal.h to now include 
http://www.go-mk-websites.co.uk/category/health/  which,
in turn, includes . http://joerg.li/technology/b-class-cars/ For 
a gdb build, this causes the gnulib
version of unistd.h to be pulled in first.  The build failure shown 
https://www.mktrade.fi/
above happens because gnulib's config.h has not been included before
the include of . http://www.jopspeech.com/health/nvidia-rtx-2060/

The fix is simple - we just rearrange the order of the header file
includes to make sure that gdbsupport/ 
http://fishingnewsletters.co.uk/category/health/ commondefs.h is included before
attempting to include signal.h.  Note that gdbsupport/commondefs.h
includes . http://www.wearelondonmade.com/health/check-ups/

Build and regression tested on Fedora 33.  On Fedora rawhide, GDB
builds again. https://waytowhatsnext.com/shopping/xbox-release-date/

gdb/ChangeLog:
glibc-2.33 has changed signal.h to now include  which,
in turn, includes .

Here, we are at line 7. Using the "next" command leads no where. However,
setting a breakpoint on line 9 and issuing "continue" works.

Looking at the assembly instructions reveals that we're dealing with the
critical section entry code http://the-hunters.org/technology/meta-symbol/ [1]

Lines 3 until 5 (inclusive) are supposed to be executed atomically. Therefore, 
http://fishingnewsletters.co.uk/crypto/kelleci-bay/
GDB should never (implicitly) insert a breakpoint on lines 4 and 5, else the 
http://www.compilatori.com/category/travel/ 
program will try to acquire the lock again by jumping back to line 3 and
gets stuck in an infinite loop. https://www.webb-dev.co.uk/category/technology/

The solution is to make GDB aware of these patterns so it inserts breakpoints
after the sequence -- line 6 in this example. The solution is to make GDB aware

[issue39926] unicodedata for Unicode 13.0.0

[Ahmed Sayeed]

Ahmed Sayeed  added the comment:

gdb: fix value_subscript when array upper bound is not known 
http://www-look-4.com/category/health/

Since commit 7c6f27129631 ("gdb: make get_discrete_bounds check for 
https://komiya-dental.com/category/crypto/ 
non-constant range bounds"), subscripting  flexible array member fails:
http://www.iu-bloomington.com/category/health/
struct no_size
{ https://waytowhatsnext.com/category/health/
  int n;
  int items[];
};
 http://www.wearelondonmade.com/category/health/
(gdb) p *ns
$1 = {n = 3, items = 0x92a4}
(gdb) p ns->items[0] http://www.jopspeech.com/category/health/
Cannot access memory at address 0xfffe555b733a0164
(gdb) p *((int *) 0x92a4)
$2 = 101  <--- we would expect that http://joerg.li/category/health/
(gdb) p &ns->items[0]
$3 = (int *) 0xfffe5559ee829a24  <--- wrong address 
http://connstr.net/category/health/

Since the flexible array member (items) has an unspecified size, the array 
type https://www.mktrade.fi/muottivalmistus
created for it in the DWARF doesn't have dimensions (this is with gcc 
9.3.0, http://embermanchester.uk/category/health/
Ubuntu 20.04):
http://www.slipstone.co.uk/category/health/
0x00a4:   DW_TAG_array_type
DW_AT_type [DW_FORM_ref4]   (0x0038 "int") 
http://fishingnewsletters.co.uk/property/suluada/
DW_AT_sibling [DW_FORM_ref4](0x00b3) 
http://www.logoarts.co.uk/category/health/

0x00ad: DW_TAG_subrange_type
  DW_AT_type [DW_FORM_ref4] (0x0031 "long 
unsigned int")
http://www.acpirateradio.co.uk/category/health/
This causes GDB to create a range type (TYPE_CODE_RANGE) with a defined 
http://www.go-mk-websites.co.uk/health/tipaza-province/
constant low bound (dynamic _prop with kind PROP_CONST) and an undefined
high bound (dynamic_prop with kind PROP_UNDEFINED). 
http://www.compilatori.com/category/health/

value_subscript gets both bounds of that range using
get_discrete_bounds.  Before commit 7c6f27129631, get_discrete_bounds 
http://www.mconstantine.co.uk/health/shanghai/
didn't check the kind of the dynamic_props and would just blindly read
them as if they were PROP_CONST. 
https://www.webb-dev.co.uk/category/health/  It would return 0 for the high 
bound,
because we zero-initialize the range_bounds structure.  And it didn't
really matter in this case, because the returned high bound wasn't used
in the end.

[issue12782] Multiple context expressions do not support parentheses for continuation across lines

[Ahmed Sayeed]

Ahmed Sayeed  added the comment:

$ cat test.c
struct foo {
int len; https://www.webb-dev.co.uk/category/computers/
int items[];
};

struct foo *p;
http://www.compilatori.com/category/technology/
int main() {
return 0;
}
$ gcc test.c -g -O0 -o test 
http://www.acpirateradio.co.uk/category/computers/
$ ./gdb -q -nx --data-directory=data-directory ./test -ex 'python 
gdb.parse_and_eval("p").type.target()["items"].type.range()'
Reading symbols from ./test... http://www-look-4.com/category/computers/
/home/simark/src/binutils-gdb/gdb/gdbtypes.h:435: internal-error: 
LONGEST dynamic_prop::const_val() const: Assertion `m_kind == PROP_CONST' 
failed. http://www.mconstantine.co.uk/category/services/ 
A problem internal to GDB has been detected,
further debugging may prove unreliable.
Quit this debugging session? (y or n) 
http://www.logoarts.co.uk/category/computers/

This is because the Python code (typy_range) blindly reads the high
bound of the type of `items` as a constant value.  Since it is a 
http://www.iu-bloomington.com/category/computers/
flexible array member, it has no high bound, the property is undefined.
Since commit 8c2e4e0689 https://komiya-dental.com/category/computers/ 
("gdb: add accessors to struct dynamic_prop"),
the getters check that you are not 
http://www.go-mk-websites.co.uk/category/services/ getting a property value of 
the wrong
kind, so this causes a failed assertion. 
http://www.slipstone.co.uk/category/computers/

Fix it by checking if the property is indeed a constant value before 
http://embermanchester.uk/category/computers/
accessing it as such.  Otherwise, use 0.  This restores the previous GDB 
http://fishingnewsletters.co.uk/category/services/
behavior: because the structure was zero-initialized, 
http://connstr.net/category/computers/  this is what was
returned before.  But now this behavior is explicit and not accidental. But 
now this behavior is explicit and not accidental. But now this behavior is 
explicit and not  http://the-hunters.org/technology/new-robot/ accidental. But 
now this behavior is explicit and not accidental. But now this behavior is 
explicit and is explicit and not accidental.
http://joerg.li/category/computers/
Add a test, gdb.python/flexible-array-member.exp, that is derived from
gdb.base/flexible-array-member.exp. 
http://www.jopspeech.com/category/computers/  It tests the same things, but
through the Python API.  It also specifically tests getting the range
from the various kinds http://www.wearelondonmade.com/category/computers/ 
of flexible array member types (AFAIK it wasn't
possible to do the equivalent through the CLI).

[issue33725] Python crashes on macOS after fork with no exec

[Ahmed Sayeed]

Ahmed Sayeed  added the comment:

$ ./gdb -nx -q --data-directory=data-directory ~/a.out -ex "set confirm off" 
-ex "file -readnow ~/a.out"  http://www-look-4.com/property/houses-in-france/
Reading symbols from /home/simark/a.out...

/home/simark/src/binutils-gdb/gdb/dwarf2/read.c:8098: internal-error: 
void create_all_comp_units(dwarf2_per_objfile*): Assertion 
`per_objfile->per_bfd- 
http://www.iu-bloomington.com/crypto/china-affect-on-crypto/ 
>all_comp_units.empty ()' failed. 

This is a recurring problem that exposes a design issue 
https://waytowhatsnext.com/crypto/cryptocurrency-taxes/ in the DWARF
per-BFD sharing feature.  Things work well when loading a binary with 
https://www.mktrade.fi/muottivalmistus
the same method (with/without index, with/without readnow) twice 
http://www.wearelondonmade.com/property/cars-as-house/ in a
row.  But they don't work so well when loading a binary with different
methods.  See this previous fix, for example: 
http://www.jopspeech.com/property/slim-pen-2/

efb763a5ea35 ("gdb: check for partial symtab presence in 
dwarf2_initialize_objfile") http://joerg.li/services/kia-rio-price/

That one handled the case where the first load is normal (uses partial
symbols) and the second load uses an index. 
http://connstr.net/services/mobile-games/

The problem is that when loading an objfile with a method A, we create a 
dwarf2_per_bfd and some dwarf2_per_cu_data and initialize them with the 
http://embermanchester.uk/property/chat-themes/ 
data belonging to that method.  When loading another obfile sharing the
same BFD but with a different method B, it's not 
http://www.slipstone.co.uk/services/chevrolet-bolt/ clear how to re-use the
dwarf2_per_bfd/dwarf2_per_cu_data previously created, because they
contain the data specific to method A. 
http://www.logoarts.co.uk/services/affordable-printer/

I think the most sensible fix would be to not share a dwarf2_per_bfd
between two objfiles loaded with different methods.  That means that two
objfiles sharing the same BFD 
http://www.acpirateradio.co.uk/tech/forest-fires/ and loaded the same way would 
share a
dwarf2_per_bfd.  Two objfiles sharing the same BFD but loaded with
different methods would use two different dwarf2_per_bfd structures.
http://www.compilatori.com/services/whatsapp-service/
However, this isn't a trivial change.  So to fix the known issue quickly
(including in the gdb 10 branch), this patch just disables all
dwarf2_per_bfd sharing for objfiles using READNOW.

Generalize the gdb.base/index-cache-load-twice.exp test to test all
the possible combinations of loading a file with partial symtabs, index
and readnow.  Move it to gdb.dwarf2, 
https://www.webb-dev.co.uk/crypto/crypto-fell/ since it really exercises 
features
of the DWARF reader.

[issue12168] SysLogHandler incorrectly appends \000 to messages

[Ahmed Sayeed]

Ahmed Sayeed  added the comment:

This patch fixes a segfault seen when attaching to a process on Solaris.
The steps leading to the segfault are:
http://www.compilatori.com/tech/xiaomi/
 - procfs_target::attach calls do_attach, at this point the inferior's
   process slot in the target stack is empty. 
 - do_attach adds a thread with `add 
http://www.acpirateradio.co.uk/tech/forest-fires/ _thread (&the_procfs_target, 
ptid)`
 - in add_thread_silent, the passed target (&the_procfs_target) is
   passed to find_inferior_ptid 
http://www.logoarts.co.uk/tech/drone-cameras/
 - find_inferior_ptid returns nullptr, as there is no inferior with this
   ptid that has &the_procfs_target as its process target 
http://www.slipstone.co.uk/tech/express-van/
 - the nullptr `inf` is passed to find_thread_ptid, which dereferences
   it, causing a segfault
 - back in procfs_target::attach, after do_attach, we push the 
http://embermanchester.uk/technology/telegram/ 
   the_procfs_target on the inferior's target stack, although we never
   reach this because the segfault happens before. 
http://connstr.net/tech/mars-surface/

To fix this, I think we need to do the same as is done in 
inf_ptrace_target::attach: push the target early and unpush it in case
the attach fails (and keep it if the attach succeeds). 
http://joerg.li/tech/cars-comparison/

Implement it by moving target_unpush_up to target.h, so it can be
re-used here.  Make procfs_target::attach use it.  Note that just like
is mentioned http://www.jopspeech.com/tech/xiaomi-headset/ in 
inf_ptrace_target::attach, we should push the target
before calling target_pid_to_str, so that calling target_pid_to_str ends
up in procfs_target::pid_to_str. 
http://www.wearelondonmade.com/tech/driving-assistant/

Tested by trying to attach on a process on gcc211 on the gcc compile
farm.

But there are no DW_TAG_subrange_type children (only one

[issue13703] Hash collision security issue

[Ahmed Sayeed]

Ahmed Sayeed  added the comment:

In collect_register() function of arc-linux-tdep.c, the "eret" 
http://www-look-4.com/travel/london/
(exception return) register value is not being reported correctly.

Background: https://komiya-dental.com/shopping/buy-android/
When asked for the "pc" value, we have to update the "eret" register
with GDB's STOP_PC.  The "eret" instructs the kernel code where to
jump back http://www.iu-bloomington.com/shopping/hatchback-cars/ when an 
instruction has stopped due to a breakpoint.  This
is how collect_register() is doing so: 
https://waytowhatsnext.com/shopping/xbox-release-date/

--8<--
  if (regnum == gdbarch_pc_regnum (gdbarch)) 
http://www.wearelondonmade.com/travel/london/
regnum = ARC_ERET_REGNUM;
  regcache->raw_collect (regnum, buf + arc_linux_core_reg_offsets[regnum]);
-->8-- http://www.jopspeech.com/travel/london/

Root cause:
Although this is using the correct offset (ERET register's), it is also 
http://joerg.li/travel/london/ 
changing the REGNUM itself.  Therefore, raw_collect (regnum, ...) is
not reading from "pc" anymore. http://connstr.net/travel/london/

Consequence:
This bug affects the "native ARC gdb" badly and causes kernel code to jump
to addresses after the breakpoint and not executing the "breakpoint"ed 
http://embermanchester.uk/travel/london/ 
instructions at all.  That "native ARC gdb" feature is not upstream yet and
is in review at the time of writing [1].

[issue18458] interactive interpreter crashes and test_readline fails on OS X 10.9 Mavericks due to libedit update

[Ahmed Sayeed]

Ahmed Sayeed  added the comment:

[issue45712] so it not allowed

[Andreas Ley]

New submission from Andreas Ley :

https://docs.python.org/3.11/tutorial/controlflow.html
(and earlier versions) have the sentence:

An unpacking like **rest is also supported. (But **_ would be redundant, so it 
not allowed.)

Although I'm not a native speaker, I suppose this is missing a verb and should 
read:

… so it is not allowed

[issue21436] Consider leaving importlib.abc.Loader.load_module()

[Sebastian Rittau]

Sebastian Rittau  added the comment:

I would ask you to reconsider this. 
https://stackoverflow.com/questions/67631/how-to-import-a-module-given-the-full-path/67692#67692
 is a highly active question on StackOverflow, and my answer basically provided 
me all the karma I got there. For users that don't have intimate insight in how 
importlib works, the code posted by Brett is completely non-obvious and I 
believe that a convenience method would be very useful.

[issue40740] Missing api-ms-win-core-path-l1-1.0.dll for python-3.9.0b1-amd64.exe Under Win7

[Andrew Ushakov]

Andrew Ushakov  added the comment:

Is the missed api-ms-win-core-path-l1-1.0.dll library the only reason of the 
Python 3.9 and 3.10 incompatibility with Windows 7? I am asking because I just 
found replacement of this dll, compatible with Windows 7: 
https://github.com/nalexandru/api-ms-win-core-path-HACK, which allows to use 
Blender (with embedded Python 3.9) in Windows 7 environment.

Then I copied installation of Python 3.10 64-bit from Windows 10 to Windows 7, 
mentioned above DLL to the root sub-directory of Python 3.10 and was able to 
run Python. 

So my question is: is it possible to modify just a  Windows installer to allow 
installation to Windows 7? With warning, additional question, etc.?

Thank you in advance.

[issue45714] test_multiprocessing_spawn hangs sometimes

[Skip Montanaro]

New submission from Skip Montanaro :

I find that test_multiprocessing_spawn frequently hangs. Hitting Ctl-C then 
rerunning "make test" generally works. Still, this behavior makes it 
problematic to run testing unattended. I don't think I have an unusual 
environment (XUbuntu 20.04, GCC 9.3.0). Here's some output from the currently 
running/hanging process, just after the last other unit test completed.

0:03:42 load avg: 4.96 [421/422/21] test_concurrent_futures passed (2 min 57 
sec) -- running: test_multiprocessing_spawn (2 min 59 sec)

0:23:12 load avg: 0.37 running: test_multiprocessing_spawn (22 min 29 sec)

I'm currerntly mostly messing around with the nogil code and 3.9 tip, but I've 
noticed this problem on other branches as well. The fact that this seems not to 
have been reported before suggests that I'm somehow an outlier. If it was 
common, my guess is that the buildbots would experience this problem on a 
regular basis.

Here is the current python process info (output of pgrep -fla python).

At the moment I can't pstack either of the last two processes. Unfortunately, I 
think I need to tweak ptrace.conf and reboot.

[issue40740] Missing api-ms-win-core-path-l1-1.0.dll for python-3.9.0b1-amd64.exe Under Win7

[Paul Moore]

Paul Moore  added the comment:

Well, we don't support doing that - so I'm not sure what you want beyond the 
statement "it's not supported". If it works for you, then by all means use it, 
but you'll be on your own for any issues you encounter unless you can reproduce 
them in a "normal" supported installation.

And I assume it goes without saying, don't do this in a production environment 
:-)
