[issue38400] Python segfaults when configured with --with-pydebug --with-trace-refs

[STINNER Victor]

STINNER Victor  added the comment:

Notes for myself.

the visit_decref() has been updated to display repr() of the parent object, 
rather than display the "freed" object.

The problem was that the None object was seen as "freed" because 
_ob_prev=_ob_next=NULL. This object doesn't seem to be part of the list of all 
objects, sys.getobjects(). I fixed Py_None, but then I got the same assertion 
error on a different (moduledef) object. I gave up, and Pablo and me fixed 
_PyObject_IsFreed() instead.

[issue38392] Ensure that objects entering the GC are valid

[Serhiy Storchaka]

Serhiy Storchaka  added the comment:

I am sure this will break third-party projects. But I thing that we should not 
revert this change, as it completely matches the documentation. It is good that 
it was applied so early at development cycle.

Stefan, could you please test Cython and lxml with this?

[issue33803] contextvars: hamt_alloc() must initialize h_root and h_count fields

[STINNER Victor]

STINNER Victor  added the comment:

Notes for myself.

In bpo-38392, I modified PyObject_GC_Track() in debug mode to detect this bug.

For example, this bug can be reproduced with this change:
---
diff --git a/Python/hamt.c b/Python/hamt.c
index 28b4e1ef6c..d7dd555d15 100644
--- a/Python/hamt.c

 return NULL;
 }
-o->h_count = 0;
-o->h_root = NULL;
 o->h_weakreflist = NULL;
 PyObject_GC_Track(o);
 return o;
---

Python now detects the bug in debug mode:
---
$ ./python -m test -v test_context

Do you mean every microbenchmark measuring single feature is meaningless?

I think it is worth enough for readers who understand what
`LOAD_GLOBAL` instruction means.
(e.g. People who using techniques like `int_ = int` before a loop.)

[issue38408] urlparse gives no method to build a url with a port

[James Allsopp]

New submission from James Allsopp :

Hi,
I like to build my Url's using url unparse, e.g.
site_to_test = urllib.parse.urlunparse((scheme, host, page, '', '', ''))
r = requests.get(site_to_test)

However, we reach a lot of sites through SSH tunnels, as our network is heavily 
locked down, and need to specify a port. Unfortunately, we can parse a url with 
a port, and get site_to_test.port = '9097' we can't run it the other way, e.g. 
this fails.
site_to_test = urllib.parse.urlunparse((scheme, host, page, '', '', 
'',port=9097))

This should be easy to fix and there's a use case for it.
Thanks

[issue38118] Valgrind warning in PyUnicode_Decode: false alarm with GCC builtin strcmp()

[STINNER Victor]

STINNER Victor  added the comment:

> ==6832==at 0x4D87E9: PyUnicode_Decode (unicodeobject.c:3395)

This warning is a false alarm: the GCC builtin strcmp() function seems to read 
past the NUL byte. When recompiling Python with -fno-builtin GCC option, the 
warning is gone.

The valgrind warning can be reproduced using attached valgrind_strcmp_warn.c:

On Fedora 30 with:

* gcc (GCC) 9.2.1 20190827 (Red Hat 9.2.1-1)
* valgrind-3.15.0

GCC builtin strcmp() emits a false alarm in valgrind: it reads past the NUL
byte.

[issue16623] argparse help formatter does not honor non-breaking space

[hai shi]

hai shi  added the comment:

I checked the help format.
the help_lines' width in python2.7 is different python3.

The width is more likely a hardcode in 
https://github.com/python/cpython/blob/2.7/Lib/argparse.py#L165.
, so the help_lines = [u'This is a very long help string. ex: "--s3', 
u's3://my.bucket/dir1/dir2"'](when joining this help_lines it will add a '\n' 
in the middle)

Since python 3.3, the width is a dynamic value in 
https://github.com/python/cpython/blob/master/Lib/argparse.py#L170
, so the help_lines = ['This is a very long help string. ex: 
"--s3\xa0s3://my.bucket/dir1/dir2"']

[issue38401] Make dataclass attribute docstrings accessible

[Eric V. Smith]

Eric V. Smith  added the comment:

Note that those strings are not docstrings, per se. They're just strings, and 
aren't available in the class definition for the dataclass decorator to see. 
It's really no different from:

class X:
x: int
3

That 3 just gets evaluated and thrown away, like the strings in your example. 
To change this is beyond the scope of dataclasses, and would need to be a 
language change. I can't think of a good way to attach the string to the 
annotation before it (I'm assuming this would only work with annotations, but 
maybe you have other ideas). You might want to bring this up on python-ideas to 
get some more feedback.

[issue38408] urlparse gives no method to build a url with a port

[Eric V. Smith]

Eric V. Smith  added the comment:

One way I can think of doing this in a backward compatible way is to add 
keyword parameters to urlunparse, like:

def urlunparse(components, *, username=None, password=None, hostname=None, 
port=None):

Which would make your call:
site_to_test = urllib.parse.urlunparse((scheme, host, page, '', '', ''), 
port=9097)

I think that's a horrible interface, but it is backward compatible.

A better interface would be have all 10 URL parameters passed in as keyword 
arguments, with reasonable defaults. If you want to keep this named 
"urlunparse", you'd need to say you can't pass in both "components" and any 
other named parameter (other than maybe the 4  parameters that are unnamed in 
ParseResult).

Something like:
def urlunparse(components=None, scheme=None, netloc=None, path=None, 
params=None, query=None, fragment=None, *, username=None, password=None, 
hostname=None, port=None):

Then error if components is set and any of scheme, netloc, path, params, query, 
or fragment is also set.

We could bikeshed about which would be keyword-only, if any, all, or only some 
as I've shown here.

Another option would be to leave urlunparse alone, and add a new function 
entirely, which wouldn't have to worry about backward compatibility.

It might be worthwhile to raise this on python-ideas.

[issue38118] Valgrind warning in PyUnicode_Decode: false alarm with GCC builtin strcmp()

[STINNER Victor]

STINNER Victor  added the comment:

The valgrind false alarm on GCC builtin strcmp() has been reported to the 
Valgrind bug tracker in 2011, with an update in 2012 and... nothing :-(
https://bugs.kde.org/show_bug.cgi?id=264936

curl worked around the issue by disabling valgrind on the impacted test:
https://lists.fedoraproject.org/pipermail/scm-commits/2011-February/567665.html

Passing "--partial-loads-ok=yes" to Valgrind has no effect... It became the 
default:

[issue36356] Failure to build with address sanitizer

[Ben Harper]

Ben Harper  added the comment:

The default build of python with ASAN builds successfully. Test suite and PGO 
build are currently blocked, but that can be separated if it makes more sense 
to handle them individually.

Would it make sense to add an ASAN build to the CI pipeline to make detection 
automatic going forward?

Yeah, please open one issue per ASAN issue (try to group similar warnings in 
the same Python issue?).


> Would it make sense to add an ASAN build to the CI pipeline to make detection

Gregory maintains a clang UBSan buildbot:
https://buildbot.python.org/all/#/builders/135

Usually I prefer to setup a buildbot when most issues are fixed.

I close this issue.

[issue38411] SQLITE_MISUSE race condition in sqlite3 is misleadingly raised as a binding error

[Jack Robison]

New submission from Jack Robison :

There is a race condition in the sqlite3 module that is misleadingly raised as 
sqlite3.InterfaceError('Error binding parameter 0 - probably unsupported type.')

There are two issues here, one is the incorrectly raise error 
(https://bugs.python.org/issue16379), the other is the underlying SQLITE_MISUSE 
caused by the race condition. I believe this is a race between sqlite3 vs 
python garbage collection due to the releasing of the GIL. If the GIL releasing 
is removed from sqlite3, I cannot reproduce the race.

Here is a script to reproduce the error, as the number of runners or 
queries_per_executemany is increased the error happens more frequently. The 
minimal test case only needs two executemanys where each has two queries to run.





import asyncio
import sqlite3
from concurrent.futures.thread import ThreadPoolExecutor


async def misuse_sqlite(runners=2, queries_per_executemany=2):
loop = asyncio.get_event_loop()

expected_error = 'Error binding parameter 0 - probably unsupported type.'
exceptions = []
executor = ThreadPoolExecutor(1)
db = executor.submit(sqlite3.connect, ':memory:', 
isolation_level=None).result()
executor.submit(db.executescript, "create table test (id text primary 
key);")

def query_in_executor():
return asyncio.wrap_future(executor.submit(executemany))

def executemany():
try:
return db.executemany("select * from test where id=?", ((str(i),) 
for i in range(queries_per_executemany)))
except Exception as err:
exceptions.append(err)

for _ in range(runners):
loop.call_soon(query_in_executor)
await asyncio.sleep(0.01)

assert all(str(err) == expected_error and isinstance(err, 
sqlite3.InterfaceError) for err in exceptions)

executor.submit(db.close).result()
executor.shutdown()

return len(exceptions) > 0


attempts = 0

while True:
attempts += 1
if asyncio.run(misuse_sqlite()):
print('error hit on attempt', attempts)
break

Łukasz - this needs a fix in 3.8, but we don't have to necessarily change the

let you make the call whether we can also add a return value to these functions.

[issue38413] Remove or change "Multithreading" section

[Vladimir Ryabtsev]

New submission from Vladimir Ryabtsev :

This is regarding the page https://docs.python.org/3.7/library/sqlite3.html.

I believe this section on the very bottom of the page has been kept here for 
pretty long time, during that both SQLite and the sqlite3 module evolved and 
improved. Now the content contradicts to the description of function 
"connect()" in the part describing "check_same_thread" parameter. The function 
description says that using connections from multiple threads is allowed with 
serialization handled by the user (and it is true), while the bottom 
"Mutithreading" section says sharing connections is not allowed.

I think we can remove "Mutithreading" section entirely unless there is 
something important to add to what already mentioned.

[issue38414] Ordering a nested dictionary in python with json format

[Umar Asghar]

New submission from Umar Asghar :

Python does not preserve ordering in JSON format. I have tested it out but it's 
not working. Here is my code.

# Python3 code to demonstrate 
# Sort nested dictionary by key 
# using OrderedDict() + sorted() 
from collections import OrderedDict 
from operator import getitem 
import json

# initializing dictionary 
test_dict = {'Nikhil' : { 'roll' : 24, 'marks' : 17}, 
'Akshat' : {'roll' : 54, 'marks' : 12}, 
'Akash' : { 'roll' : 12, 'marks' : 15}} 

# printing original dict 
print("The original dictionary : " + str(test_dict)) 

# using OrderedDict() + sorted() 
# Sort nested dictionary by key 
res = OrderedDict(sorted(test_dict.items(), 
key = lambda x: getitem(x[1], 'marks'))) 

print("The sorted dictionary by marks is : " + str(res))
# Output
# The sorted dictionary by marks is : OrderedDict([('Akshat', {'marks': 12, 
'roll': 54}), ('Akash', {'marks': 15, 'roll': 12}), ('Nikhil', {'marks': 17, 
'roll': 24})])

res = json.dumps(res)

# print result 
print("The sorted dictionary by marks is : (json)")
print(json.loads(res)) 
# Output
# The sorted dictionary by marks is : 
# {'Akash': {'marks': 15, 'roll': 12}, 'Akshat': {'marks': 12, 'roll': 54}, 
'Nikhil': {'marks': 17, 'roll': 24}}
Does anyone suggest any solution for it?

It's different than a simple dictionary. It only targets the nested dictionary 
ordering. Please don't mark it a duplication of simple dictionary ordering with 
JSON. thanks
