[issue26053] regression in pdb output between 2.7 and 3.5

[STINNER Victor]

STINNER Victor  added the comment:

> If we want to backport then we need both PRs.

Commit 652bfdee9495dca241d48278742fe035b7a82bdb is a bugfix and this issue is 
marked as Python 3.8-3.10, so yeah, a backport is worth it.

You can create a PR for Python 3.9 combining the two commits. I like to use 
"git cherry-pick -x " manually for that. And then, use the label to 
backport this PR to Python 3.8.

[issue37804] Remove Thread.isAlive in Python 3.9

[STINNER Victor]

STINNER Victor  added the comment:

> The threading documentation for 3.9 still claims "While they are not listed 
> below, the camelCase names used for some methods and functions in this module 
> in the Python 2.x series are still supported by this module." It would be 
> better to mention when isAlive was removed.

Do you want to propose a PR for that?

I see still 4 camelCase methods in threading.Thread:

* 'getName' => Thread.name can be get
* 'setName' => Thread.name can be set
* 'isDaemon' => Thread.name can be get
* 'setDaemon' => Thread.daemon can be set

[issue43664] Long computations in pdb.run() lead to segfault

[Ronald Oussoren]

Ronald Oussoren  added the comment:

```pdb.run(...)``` is ends up in ```bdb.Bdb.run```, which uses compile and exec 
to run the code.

And indeed:

>>> compile("1+2" * 100, "-", "exec")
zsh: segmentation fault  python3.9

[issue43703] xml.etree parser does not accept valid control characters

[Romuald Brunet]

New submission from Romuald Brunet :

Python XML parser (xml.etree) does not seems to allow control characters that 
are invalid in XML 1.0, but valid in XML 1.1 [1] [2]


Considering the following sample:


import xml.etree.ElementTree as ET

bad = 'bar  baz'
print(ET.fromstring(bad))


The parser raises the following error:
ParseError: reference to invalid character number: line 1, column 30

[issue37804] Remove Thread.isAlive in Python 3.9

[Jelle Zijlstra]

Jelle Zijlstra  added the comment:

Sure, I can submit a PR. While we're at it, we should probably also deprecate 
the setter/getter methods that you mention.

Here's what I propose doing:
- On 3.10 (or 3.11 if it's too late for 3.10), make getName and friends throw a 
DeprecationWarning, scheduling them for removal in 3.12 or 3.13
- On 3.8 and lower, update the docs to explicitly call out the names of the 
deprecated methods
- On 3.9 and higher, update the docs similarly but mention that 
threading.isAlive was already removed

If there's no objection, I'll open separate issues and PRs for these in a few 
days.

[issue43688] [C API] Support the limited C API in debug mode (Py_INCREF and Py_DECREF)

[STINNER Victor]

STINNER Victor  added the comment:

I modified my PR 25131 to only implement Py_INCREF/Py_DECREF as opaque function 
calls under two conditions:

* Python is built in debug mode
* Py_LIMITED_API macro targets Python 3.10 or newer

So this PR 25131 now only has an impact on performance if Python is built in 
debug mode. Performance on Python built in release mode is not affected.

[issue43688] [C API] Support the limited C API in debug mode (Py_INCREF and Py_DECREF)

[STINNER Victor]

STINNER Victor  added the comment:

In release mode, I get the libraries:

* xxlimited.cpython-310-x86_64-linux-gnu.so
* xxlimited_35.cpython-310-x86_64-linux-gnu.so

In debug mode, I get the libraries:

* xxlimited.cpython-310d-x86_64-linux-gnu.so
* xxlimited_35.cpython-310d-x86_64-linux-gnu.so

It's still a different ABI: "cpython-310" vs "cpython-310d" ("D" for debug). So 
there is risk to be confused between the stable ABI in release mode and the 
stable ABI in debug mode :-) I don't how how to get the ".abi3.so" suffix.

[issue43703] xml.etree parser does not accept valid control characters

[Serhiy Storchaka]

Serhiy Storchaka  added the comment:

It is a known issue, see issue11804 and issue39512.

In short, the underlying library for XML parsing (expat) does not support XML 
1.1 and does not have plans to support it. And seems that XML 1.1 is a dead 
standard if it is not supported in popular parsing libraries.

[issue43703] xml.etree parser does not accept valid control characters

[Romuald Brunet]

Romuald Brunet  added the comment:

Thanks for the quick reply

We're getting data from about a hundred different providers around the world; 
some of them not really keen on standards, so we already have some hacks to fix 
invalid XML. We'll add one to the list

In that particular case, the XML was invalid anyway since it was an XML 1.0 
document, and the character was sent as "binary" (\x19)

I removed almost all messages of this issue since most of them looked list 
SPAM. I also blocked user accounts who posted SPAM. If it was a mistake, 
contact me.

This is the Python bug tracker, not a forum to ask questions how to use Python, 
or to report bugs in your website.

Multiple comments were written in French, whereas this bug tracker is in 
English.

I even hesitate to close the issue since it got too many SPAM comments.

[issue43705] [docs] Document that SyntaxError's offsets are 1-indexed

[Ammar Askar]

As pointed out by Guido in https://bugs.python.org/issue43555, we switched to 
making the column offsets for SyntaxError be 1-indexed consistently in

The rationale is explained by Guido and expanded upon in follow up comments 
here: https://github.com/python/cpython/pull/9338#pullrequestreview-155989089 

This property however was not actually ever added to SyntaxError's 
documentation: https://docs.python.org/3/library/exceptions.html#SyntaxError

[issue27129] Wordcode, part 2

[STINNER Victor]

STINNER Victor  added the comment:

I get two crashes on Windows with Python built in debug mode:

* I got a crash. I wasn't sure if it was an issue of incremental build, so I 
rebuilt Python.
* On a fresh build, Python crashed on the CALL_FUNCTION_KW opcode, when loading 
names, names was equal to 0x:

names = POP();
assert(PyTuple_Check(names)); <=== HERE

  Moreover, f->f_code was equal to 0xCBCBCBCBCBCBCBCB. But it was really weird. 
I added assertion to ensure that f->f_code was not equal 0xCBCBCBCBCBCBCBCB: 
the assertion didn't fail.

* I ran "git clean -fdx" and built again Python. This time, it went fine, 
moreover the whole test suite passed cleanly!? "== Tests result: SUCCESS ==" 
and "386 tests OK."

I build Python with:

   PCbuild\build.bat -d -p x64 -e

[issue43707] onerror in tempfile has an invalid raise expression

[Maximilian Roos]

New submission from Maximilian Roos :

The raise expression 
[here](https://github.com/python/cpython/blob/ad442a674ca443feec43a88a2d3671784712e550/Lib/tempfile.py#L826)
 isn't valid, since it isn't in an except block.

It'll still raise, given it's invalid, though not with the exception it should 
be raising with...

I think this diff will fix it, I can put this in as a PR if that's reasonable. 
Though I'm not sure how to test it — we need to generate an error that's not 
covered by the existing cases. 

```diff

[issue27129] Wordcode, part 2

[David Bolen]

David Bolen  added the comment:

Ah, Victor, that helps.  I was having trouble reproducing the problem on a 
different system.  I was suspecting a small difference in compiler version, but 
I hadn't considered it being because I started fresh.

>From what I can see, a particular build tree can be successful if it remains

But a pristine checkout on the buildbot of the latest master works, as does a 
git clean on the tree. 

I always use the buildbot scripts for building and they invoke a full clean 
first.  So either the clean process on Windows is missing something, or there's 
an artifact that is supposed to be kept in sync in the source tree itself that 
isn't.  I'm not familiar enough with the internals to guess at which yet.  I 
suppose given that it's not a problem on other buildbots argues for the clean 
issue, although I suppose it could also be something that is only kept in the 
tree to benefit a subset of systems, like Windows.

(While resetting the checkouts on the buildbot should therefore fix the current 
exceptions, I'm going to leave that alone for the moment, since that leaves it 
positioned to confirm any subsequent fix)

[issue42380] Build windows binaries with MS VS2019 16.8+ / MSVC 19.28+

[Steve Dower]

Steve Dower  added the comment:

Closing this as not a bug, since the toolchain used to build CPython itself has 
no impact on the toolchain that extensions can use.

If your build tool is not detecting newer versions of MSVC, you'll need to file 
that against whichever backend you are using.

[issue27129] Wordcode, part 2

[David Bolen]

David Bolen  added the comment:

I'm out of time for a bit, but it appears that the root issue is old pyc files 
in Tools/clinic/__pycache__ that aren't removed during a clean process, and 
appear to be the source of all of the errors.  Manually pruning that folder 
fixes things.

I believe the regular (non-Windows) makefile automatically prunes all 
__pycache__ folders in the tree during clean which is probably why that's not 
an issue on other systems.

onerror() is always called to handle an exception, and `raise` will re-raise 
that exception. Is there a specific case where this isn't working as expected 
for you?

[issue43704] ShareableList() raises TypeError when passing "name" keyword

[Steve Newcomb]

Steve Newcomb  added the comment:

And again with 3.8.8, with the same result.

I also tried just using the same shared memory manager again within the same 
process, just as shown in the documentation.  Same result:

TypeError: ShareableList() got an unexpected keyword argument 'name'

I must be missing something too obvious for me to see it?  Or has ShareableList 
not worked at least since 3.8.8?

[issue42248] Raised exception in Enum keeping user objects alive unnecessarily

[Mark Dickinson]

Mark Dickinson  added the comment:

I'm running into this, too, on Python 3.9.2; in my case it's causing 
segmentation faults in a wxPython-based application. 

Those segfaults aren't the fault of the reference cycle, of course; they're a 
result of wxPython being finicky about object cleanup order, but the existence 
of the enum reference cycle does make it harder to maneuver wxPython into a 
place where it doesn't crash.

Python 3.9.2 (default, Mar 31 2021, 05:47:22) 
[Clang 11.0.3 (clang-1103.0.32.62)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import signal
>>> class App: pass
... 
>>> def create_app():
... app = App()
... signal.signal(signal.SIGINT, signal.SIG_DFL)
... 
>>> create_app()

At this point, since the App() instance was local to create_app, and wasn't 
returned, I'd expect there to be no App objects alive in the system. But it 
turns out there's still an App object being kept alive:

>>> import gc
>>> [obj for obj in gc.get_objects() if type(obj) is App]
[<__main__.App object at 0x10acb3d90>]

The cause is a call to _int_to_enum in signal.py which attempts to coerce the 
default signal handler to an element of Handlers. That coercion fails, leaving 
an exception

  ValueError(' is not a valid Handlers')

The traceback on that exception leads to the frame containing the call to 
Enum.__new__, which in turn contains a reference ve_exc back to the exception.

[In the real code, App was a wx.App object, and the App.__init__ method played 
the role of create_app.]

[issue43707] onerror in tempfile has an invalid raise expression

[Maximilian Roos]

Maximilian Roos  added the comment:

I see @eryksun — by convention `onerror` is always called in an except block, 
and so having a bare `raise` outside of an explicit except block is OK.

Thanks for clarifying. I'll close this.

[issue43708] Tkinter theme settings object schema is missing

[WHK]

New submission from WHK :

By example

style = ttk.Style()
style.theme_settings('default', settings={
'.': []
})

Tkinter settings schema or typed data is missing. By example:

_tkinter.TclError: Invalid state name d

This error message does not provide the missing parameter information, by 
example expected: "Tupe is required in .::Map background, not dict"

[issue43709] Windows Tools\buildbot\clean.bat misses some needed pyc/pyo removal

[David Bolen]

New submission from David Bolen :

The Tools\buildbot\clean.bat script used on Windows only removes pyc/pyo files 
from the Lib tree, leaving some files beneath Tools (clinic and peg_generator) 
and Parser (asdl).  This can cause failures following commits that affect those 
files, such as fcb55c0037baab6f98f91ee38ce84b6f874f034a (in issue #27129) 
leading to subsequent crashes or anomalous behavior.

This appears to have been true for a while, though only the 3.10 branch ran 
into the issue, so any fix might also be back-ported to the other active 
branches.

[issue27129] Wordcode, part 2

[David Bolen]

David Bolen  added the comment:

I've opened issue #43709 for fixing the buildbot clean script under Windows.  
It needs to clean the Tools and Parser trees, not just Lib (and there are a few 
other folders involved besides clinic)

[issue43709] Windows Tools\buildbot\clean.bat misses some needed pyc/pyo removal

[David Bolen]

David Bolen  added the comment:

Something like this is a quick 'n dirty minimal fix - at least it seems to 
solve the problem that arose in issue #27129 on the Win10 buildbot:

--- a/Tools/buildbot/clean.bat
+++ b/Tools/buildbot/clean.bat
@@ -11,6 +11,8 @@ call "%pcbuild%\build.bat" -t Clean -k -d %*
 
 echo Deleting .pyc/.pyo files ...
 del /s "%root%\Lib\*.pyc" "%root%\Lib\*.pyo"
+del /s "%root%\Tools\*.pyc" "%root%\Tools\*.pyo"
+del /s "%root%\Parser\*.pyc" "%root%\Parser\*.pyo"
 
 echo Deleting test leftovers ...
 rmdir /s /q "%root%\build"

but since this only covers the buildbot script, someone working within the 
regular VS IDE and just using the clean target of the projects could presumably 
run into the same issue.  Or is there some other way to fully clean a working 
tree from within the IDE?  Not sure how important that is to address in any 
event.

[issue43684] Add combined opcodes

[Guido van Rossum]

Guido van Rossum  added the comment:

Microbench results for ADD_INT:
https://github.com/python/cpython/pull/25090#issuecomment-810441738

I have a few others like this lined up -- Mark recommended submitting them one 
at a time to make review easier.

My philosophy here (which I learned from Tim Peters in the early 2000s) is that 
even though each individual improvement has no measurable effect on a general 
benchmark (as shown in the same comment), the combined effect of a number of 
tiny improvements can be significant.

We have reached a point where there are very few individual changes possible 
that still have a significant effect, but we should not use this as an excuse 
to stop trying to improve performance.

I have mislaid the results that made me think this particular opcode is a good 
candidate; I will go back to reproduce that result and get back to you here.
