[issue37369] Issue with pip in venv on Powershell in Windows

Yeah, it's a bit more complex. Sometimes it's needed and often not, depending 
on platform. For multiprocessing we need it on Windows because of the handle 
inheritance that's used, which only goes one subprocess deep,and we use special 
knowledge to make it work even in a venv.

But at least having it there means we can use it when needed without having to 
define its semantics for 100% of cases. Venvs make things really hard the way 
they're currently done...

[issue37434] Segfault in typeobject.c at _PyObject_GC_UNTRACK(type)

[Tim Peters]

Tim Peters  added the comment:

I haven't used protobuf, but it's _generally_ true that crashes that occur for 
the first time in the presence of C or C++ extension modules are due to subtle 
(or not so subtle) mistakes in using the sometimes-delicate Python C API.  So 
it's too soon to play "pin the blame on the donkey here" ;-)  But resolving it 
really needs someone who knows what protobuf is doing.

[Timothy Lusk]

Timothy Lusk  added the comment:

I'll admit I don't know enough about Python c extensions to make that call, but 
the fact that it wasn't crashing in the protobuf extension itself during the 
import but instead during the next garbage collection made me believe it was a 
Python bug. Maybe that's not a correct assumption though.

[issue37448] obmalloc: radix tree for tracking arena address ranges

[Neil Schemenauer]

New submission from Neil Schemenauer :

This patch implements an alternative version of obmalloc's address_in_range().  
It uses a radix tree to map the areas of memory covered by obmalloc arenas.  
pymalloc_free() uses address_in_range() to determine if a block of memory is 
controlled by obmalloc or has been allocated by the system allocator.  The 
address_in_range() function must be fast.

The current version of address_in_range() uses a slightly memory unsanitary 
scheme.  I.e. it reads memory that has possibly not been initialized.  In 
theory that is not allowed and could cause a crash.  In practice, it has worked 
reliability for many years.  There is some ugly logic in obmalloc.c to disable 
sanity checking (e.g. ASN, TSAN, MSAN).  One advantage of this radix tree 
approach is that it doesn't have this unsanitary behavior.

Another small advantage of the radix tree approach is that it is independent 
from the OS page size.  With the current address_in_range() scheme, the size of 
obmalloc pools are limited to the size of the OS page size.  If larger, a 
segmentation fault could occur.  Bug #37211 (obmalloc: eliminate limit on pool 
size) allows for larger pools but at the cost of some additional code 
complexity and some additional memory overhead.

This patch has been discussed quite a bit on the python-dev list.  Thread 
subjects are:
obmalloc (was Have a big machine and spare time? Here's a possible Python 
bug.)
radix tree arena map for obmalloc

That discussion focuses quite a bit on the value of increasing the obmalloc 
arena and pool sizes.  This proposed patch keeps the sizes the same.  We can 
evaluate changing the sizes as a different issue.

I have run the pyperformance benchmark suite to compare performance of the 
radix tree with the status quo.  I think there is no significant difference for 
the programs that are part of the suite.  The pyperformance comparision report 
is attached.

If we do decide to go with larger pool and arena sizes, the radix tree approach 
actually uses less memory than the "big pools PR" (Bug #37211).  Attached is 
Tim's program to compare memory overheads of the different approaches.

I think it is worth considering using the radix tree by default on 64-bit 
platforms.  It seems to be not any slower than the status quo, does not have 
the memory unsanitary behavior and gives us the ability to easily increase pool 
sizes if we decide we want to.

Not really, I don't have a use case here. I'm just warning that this would 
break user code that relies on old behavior.

Anyway is possible to add new behavior without changing the old one. A 
parameter would make this possible, for example.

This is only my opinion, let's other argue too

[issue37374] Minidom does not have to escape quote inside text segments

[Mitar]

Mitar  added the comment:

Sure, but is old behavior useful in any use case? Every bugfix changes old 
behavior in an irreversible way.

So in which use case you want the old behavior? Can you elaborate here?

[issue7202] "python setup.py cmd --verbose" does not set verbosity

[Avinash Sajjanshetty]

Avinash Sajjanshetty  added the comment:

I would like to take this up task and propose a patch. However, I am not able 
to reproduce this issue on my machine (3.7.1). Does the issue seem to be fixed?

Here is what I tried: 

1. 

python setup.py --verbose build

I got the verbose build, as expected. 

2. 

python setup.py build --verbose 

In this case, it seems to have ignored the verbose option, as I got a normal 
(non-verbose) output. 

3. since the issue is with `verbose`, I tried quiet. 

python setup.py --quiet build

I got a quiet build. 

4. 

python setup.py build --quiet 


it ignored the quiet option, as I got a normal output.


5. I also tried a non-existent option. In the following both cases, I got an 
error saying 

error: option --qqqp not recognized


for 


python setup.py --qqqp build


and 


python setup.py build --qqqp

[issue37380] subprocess.Popen._cleanup() "The handle is invalid" error when some old process is gone

[Ruslan Kuprieiev]

Ruslan Kuprieiev  added the comment:

The `_active` code is pretty old and has not changed since 2.7, so it makes 
sense to backport it for now(also, should be very trivial to do that). To me, 
it doesn't seem dangerous to backport that, but I would love to hear what Eryk 
and others think :)

[issue37447] Nested For Loop in Python not working as Expected after cnt=2136

[Karthikeyan Singaravelan]

Karthikeyan Singaravelan  added the comment:

@pradnyan The break statement [0] only exits the for loop where it's present in 
this the one where y is involved so the outer loop involving x will continue to 
execute. So after every attempt where y = 0 the cnt value succeeds and breaks 
out of the loop. I think this is a problem with the logic that you want to 
refactor and not a problem with CPython.

def test():
cnt=0
for x in range(3216):
for y in range(2136):
cnt = cnt + 1
print("cnt="+str(cnt)+" y=" + str(y) + " x=" + str(x) )
if cnt > 2137 : 
break # Break only out of "for y in in range(2136)"

In future reports please also don't add many people to the nosy list.

[Michele Angrisano]

I don't get that output on 3.8.0a4+. I'm on OSX.
Anyway, I think that 1 should be cast with unsigned.

What do you think?

[issue37447] Nested For Loop in Python not working as Expected after cnt=2136

[Pradnyan]

New submission from Pradnyan :

I have come across very strange Python bug in nested for loops:
See below nested for loop with range function and its not working as expected.

It worked fine until cnt=2136 and start giving unexpected output after that. 

As per logic y value should get incremented for every x value but after 
cnt=2136 the y value remains 0 and x gets incremented and also
code did not stop for cnt>2137 and it halts only at 5352.

I have attached actual python code and its output. This code is executed on 
latest python build 3.7.3

Erroneous output 

cnt=2134 y=2133 x=0
cnt=2135 y=2134 x=0
cnt=2136 y=2135 x=0
cnt=2137 y=0 x=1
cnt=2138 y=1 x=1
cnt=2139 y=0 x=2
cnt=2140 y=0 x=3
cnt=2141 y=0 x=4

==
==
Python code:
==
 cnt=0
for x in range(3216):
for y in range(2136):
cnt = cnt + 1
#print("y="+str(y)+" x="+str(x)+" pixel="+str(im_ary[y,x]))
print("cnt="+str(cnt)+" y=" + str(y) + " x=" + str(x) )
if cnt>2137 :
break

[issue19696] Merge all (non-syntactic) import-related tests into test_importlib

[aeros167]

aeros167  added the comment:

> Thanks for the PR, aeros167! BTW, if you want to open a new issue and 
> modernize the tests to use importlib directly that would be great!

Sounds good, I'll definitely look into doing that after finishing up this 
issue. Was waiting the previous PR to be merged before replacing the deprecated 
method "random.choose" with "random.choice" in "test_pkg_import.py" and then 
also moving the other two into test_importlib. 

Thank you very much for the timely feedback. This has been a great experience 
for learning to contribute to larger open source projects. It's been an 
aspiration of mine to give back to Python, as it was my first serious 
programming language 5 years ago. This may be an incredibly minor contribution 
in the grand scheme of things, but my goal is for it to be the first of many (:

[issue36656] Please add race-free os.link and os.symlink wrapper / helper

[Tom Hale]

Tom Hale  added the comment:

I've created a PR here:

https://github.com/python/cpython/pull/14464

Only shutil.symlink is currently implemented.

Feedback sought from Windows users.

@Michael.Felt please note that `overwrite=False` is the default.

@taleinat I hope that the new implementation addresses the infinite loop 
concern.

Please be both thorough and gentle - this is my first PR.

[issue36422] tempfile.TemporaryDirectory() removes entire directory tree even if it's a mount-point

[Giampaolo Rodola']

Giampaolo Rodola'  added the comment:

> in case a filesystem has been mounted on the temporary directory, this can 
> lead to the entire filesystem being removed

-1

That is expected behavior and the use case looks pretty unusual. Such a new 
parameter wouldn't even be supported by other "batteries" since there's no 
portable/standard way to either mount or unmount a directory (in fact you had 
to use a subprocess in your unit-tests).

A `delete=bool` parameter would be a more reasonable proposal in principle but:
1) if you want to keep the directory around then you can just use 
tempfile.mkdtemp() (see "there should preferably be only one way to do it")
2) it would conflict with the context manager usage which is expected to delete 
the dir on ctx manager exit

In summary, I think this would over-complicate the API for no good reason. 
I'm closing this out as rejected.
