[issue34398] Docs search does not index glossary

[Jonathan Fine]

New submission from Jonathan Fine :

The docs contain a very useful page https://docs.python.org/3.5/glossary.html. 
However, the search feature does not index the glossary.

Thus, the search https://docs.python.org/3.5/search.html?q=iterable does not 
produce the helpful glossary entry
===
iterable
An object capable of returning its members one at a time. Examples of iterables 
include all sequence types (such as list, str, and tuple) and some non-sequence 
types like dict, file objects, and objects of any  [...]
===

#788509 is the only docs issue I could find, whose title contains glossary. It 
gives insight into the thoughts then about the tutorial. In msg44460 Skip 
Montaro says (1) that the glossary is "for the tutorial", and (2) he'd like to 
improve links into the tutorial. 

I suggest that part of the fix for this issue is on the home page page Glossary 
in the first grouping "Parts of the documentation."

[issue34399] [TLS] Update test keys to >= 2048bit

[Christian Heimes]

New submission from Christian Heimes :

Downstream vendors have started to tighten security. 1024 bits RSA and DH 
params are no longer considered as secure. Python 3.7 and master already use 
2048 bits RSA keys for some tests (bpo-32602). 3.6 and 2.7 don't have 1024bit 
keys. DH params and some other certs are still 1024 bits.

I'm going to update all keys and parameters to 2048.

[issue34395] memory leaks in error handling in csv and pickle modules

[Sergey Fedoseev]

Sergey Fedoseev  added the comment:

> Could you elaborate a bit more on how/where the leak happens?

It happens when PyMem_Resize() fails. It was used like this:

Py_UCS4 *field = self->field;
self->field = PyMem_Resize(field, Py_UCS4, self->field_size);

The last statement changes both self->field and field (macro magic!), so in the 
case PyMem_Resize() fails, previously allocated memory can't be freed.

[issue34387] Deletion of attributes in dataclass is buggy

[Eric V. Smith]

Eric V. Smith  added the comment:

I assume this is the behavior you're seeing:

>>> @dataclass
... class C:
...   i: int = 0
...
>>> c = C(10)
>>> c
C(i=10)
>>> del c.i
>>> c
C(i=0)
>>> del c.i
Traceback (most recent call last):
  File "", line 1, in 
AttributeError: i
>>>

If so, that's the expected behavior. You're deleting an instance attribute, so 
that the class attribute with the same name is seen.

This also happens without dataclasses:

>>> class C:
...   i = 0
...   def __init__(self, i):
... self.i = i
...
>>> c = C(10)
>>> c.i
10
>>> del c.i
>>> c.i
0
>>> del c.i
Traceback (most recent call last):
  File "", line 1, in 
AttributeError: i
>>>

If you're seeing something different, please re-open this issue.

[issue34402] [SOLUTION] strftime fails on HP-UX

[Michael Osipov]

New submission from Michael Osipov <1983-01...@gmx.net>:

strftime() fails on HP-UX. It is mapped to wcsftime(3). It has a quirk on HP-UX 
that is does not conform to POSIX. To enable POSIX compat one has to do 
(excerpt from manpage):
> APPLICATION USAGE
>   The "Unix Standards Only" prototype of wcsftime() is available to
>   applications if they are:
>a. c99 conformant.
> 
>b. Compiled with -D_XOPEN_SOURCE macro with a value >=500.
> 
>c. Compiled with -D_POSIX_C_SOURCE macro with a value >= 200112.
> 
>   Also the application must be compiled with the environment variable
>   UNIX_STD set to the value 98 or above and exported.

b and c are satasfied according to config.log. Let's get to a). The manpage of 
aCC says:
>  EXTERNAL INFLUENCES
> Environment Variables
>   [...]
>   UNIX95 or UNIX_STD specify the XPG4 behavior for c89(1) and c99(1).
>   -D_XOPEN_UNIX is also set.  UNIX_STD must be set to 1995, 1998 or
>   2003.  Both these variables cause an appropriate object file to be
>   linked into executables in order to customize libc to match ISO/IEC
>   9899:1990/Amendment 1:1995 (1995) and the C++ and C99 Standards for
>   the various wide char (1998) or other C99 libc functions (2003).
>   NOTE: 2003 is only available on HP-UX 11.31.

So one must at least do "export UNIX_STD=1998".

I am quite certain that other parts of Python are affected too.

The safest bet would be actually to test wcsftime at configure time wether the 
output is fine and have this env var set in the Makefile, unfortunately, this 
will only work for GNU make. Alternatively, a warning at the very end of the 
configure run has to be printed to export this env var.

If done, test_strftime and test_teststrptime will pass flawlessly.

[Michael Osipov]

Michael Osipov <1983-01...@gmx.net> added the comment:

The worst thing about wcsftime(3) is that it silently fails by not writing to 
output buffer. timemodule.c allocates more and more memory and then gives up.

[issue34393] json.dumps - allow compression

[Eric V. Smith]

Eric V. Smith  added the comment:

There are too many types of compression for this to be built-in to json. 
There's zlib, gzip, bzip, zip, and no doubt dozens of others. How would we 
chose one, or several? Which to leave out? How to pass in the many parameters 
to all of these compression algorithms?

As rushter points out, if your current compression library only compresses a 
file on disk, you should switch to a streaming compressor, like 
zlib.compressobj or gzip.GzipFile.

If Google Storage won't let you pass a streaming compressor as a parameter, 
then that should be a feature request to Google. I suspect you can actually 
pass a streaming compressor to it, but I have't investigated their API.

In any event, compression does not belong in the json library.

I tried to understand the issue, but my Python knowledge is too low, especially 
I do not understand by a byte array "arg = 'h\xe9\u20ac'.encode('utf-8')" is 
passed as one arg to the forked process.

I highly assume that this is related to the non-standard, default character 
encoding on HP-UX: https://en.wikipedia.org/wiki/HP_Roman#HP_Roman-8 (roman8).

A stupid 8 bit encoding. The very same snippet on FreeBSD says:
> $ LC_ALL=C python3.6 test_utf8.py
> US-ASCII:[]

Willing to test and modify if someone tells what to do.

[issue34393] json.dumps - allow compression

[liad]

liad  added the comment:

True there are endless versions of compression just like there are endless 
version of file formats. Still there are some build-ins like conversion from 
string to json. For example you don't support of json to orc file. Same 
argument could have been raise here : how would we choose which conversions to 
also? Still a choice has been made and some basic conversion behavior is 
supported.

You are claiming that it's all or nothing which I don't think is the right 
approach.

Many are now moving their storage into cloud platforms. The storage is as it 
sound - storage. It doesn't offer any programming service what you stream is 
what you will have. Streaming huge files without compression = bleeding money 
for no reason. Saving the files to disk, compress them and then upload them 
might be very slow and also the idea is having machine with big memory and low 
storage - if you have to save huge files localy you'll also need big storage 
which costs more money.

Regarding google there is a pending request for who chooses to use 
GoogleCloudPlatform package but not all use that. 

https://github.com/GoogleCloudPlatform/google-cloud-python/issues/5791

Not to mention that there are dozes of other service providers. So even if 
Google will support it - this doesn't give answer to storage service providers 

I still claim that this is a basic legit request and can be handled by the 
json.dump() function.

gzip is fine. It also supported by pandas extension and is well known.

The bug is in the test class, not cause by HP-UX.
Lib/test/test_time.py:713 says "self.assertEqual(self.yearstr(-1), self._format 
% -1)" where self._format is set in line 654 to "_format = '%04d'" because

Unfortunately, the zero padding in printf() applies to the entire string 
length. So

on HP-UX, Linux and FreeBSD.

The format string must add an additional zero for negative numbers.

[issue34393] json.dumps - allow compression

[Eric V. Smith]

Eric V. Smith  added the comment:

If you really want to see this added to Python, then I suggest you put together 
a proposal on what the API would be, what options you would or wouldn't 
support, and post that on python-ideas. But I'll warn you that your chances of 
success are low.

Your better chance of success is to write a wrapper around json and whatever 
compression library you want to use, and post that to PyPI to see if it gets 
traction. I believe you can do what you want without a temporary disk file.

[issue34393] json.dumps - allow compression

[liad]

liad  added the comment:

I'm sure I will find a work-around.
I posted it for other who will face the same issue as me.
There are many who uses cloud storage but not many work with PB size files. 
This will likely to change in the near future as more and more company start to 
process huge amount of data.

I'm not sure what you mean by designing an API. I think you sale it up for no 
need. It simply add of optional parameter which will trigger compression of 
gzip. That's it. Nothing sophisticated. 

Something like:

json.dumps(data, outfile, sort_keys=True,compression='gzip')

compression - Optional. A string representing the compression to use in the 
output. Allowed values are ‘gzip’.

[issue34398] Docs search does not index glossary

[Jonathan Fine]

Jonathan Fine  added the comment:

Good discovery. The glossary uses the RST glossary directive.
https://github.com/python/cpython/blob/master/Doc/glossary.rst

The Sphinx docs have a glossary, which is indexed by its search.
http://www.sphinx-doc.org/en/master/search.html?q=domain

So maybe Sphinx already has the functionality we require. Perhaps it's simply a 
matter of configuring the Python docs to use it. (This is optimism.)

[issue34407] datetime.time.isoformat function has inconsistent behavior with timezone

[Maksym Shalenyi (Enkidulan)]

New submission from Maksym Shalenyi (Enkidulan) :

In some cases datetime.time.isoformat shows timezone info, but in some does 
not. Consider the example below.

import datetime
import pytz

t = dict(hour=12, minute=31, second=21, microsecond=213456)

# `datetime.time.isoformat` has inconsistent behavior. Some of printed has 
timezone, but others does not.
print(datetime.time(tzinfo=pytz.timezone('Asia/Seoul'), **t).isoformat())
print(datetime.time(tzinfo=pytz.timezone('Etc/GMT-9'), **t).isoformat())
print(datetime.time(tzinfo=pytz.timezone('Australia/Sydney'), **t).isoformat())
print(datetime.time(tzinfo=pytz.timezone('Etc/UTC'), **t).isoformat())
# output:
# 12:31:21.213456
# 12:31:21.213456+09:00
# 12:31:21.213456
# 12:31:21.213456+00:00



# `datetime.time.isoformat` is inconsistent with `datetime.datetime.isoformat`. 
`datetime` objects always shows tz information when tz is present.
d = dict(year=2018, month=2, day=2, **t)
print(datetime.datetime(tzinfo=pytz.timezone('Asia/Seoul'), **d).isoformat())
print(datetime.datetime(tzinfo=pytz.timezone('Etc/GMT-9'), **d).isoformat())
print(datetime.datetime(tzinfo=pytz.timezone('Australia/Sydney'), 
**d).isoformat())
print(datetime.datetime(tzinfo=pytz.timezone('Etc/UTC'), **d).isoformat())
# output:
# 2018-02-02T12:31:21.213456+08:28
# 2018-02-02T12:31:21.213456+09:00

[issue34356] Add support for args and kwargs in logging.conf

[Vinay Sajip]

Vinay Sajip  added the comment:

There aren't any changes planned to the fileConfig code, other than bug fixes. 
If you need improved functionality, you can use dictConfig, which already 
supports improved configuration features when compared to fileConfig.

The fileConfig API was present when the logging package was first added to 
Python, and dictConfig is a later enhancement (PEP 391).

[issue11192] test_socket error on AIX

[Michael Felt]

Michael Felt  added the comment:

The original error reported was fixed by AIX - in AIX 6.1.

It will remain unresolved in AIX 5.3.

There are currently two other errors in test_socket.

FAIL: test_getnameinfo_ipv6_scopeid_symbolic 
(test.test_socket.GeneralModuleTests)
--
Traceback (most recent call last):
  File "/data/prj/python/git/python3-3.7/Lib/test/test_socket.py", line 1649,

self.assertEqual(nameinfo, ('ff02::1de:c0:face:8d%' + test_interface, 
'1234'))
AssertionError: Tuples differ: ('ff02::1de:c0:face:8d', '1234') !=

- ('ff02::1de:c0:face:8d', '1234')
+ ('ff02::1de:c0:face:8d%en0', '1234')
?   

I assume the capital D in the argument in the test:
sockaddr = ('ff02::1de:c0:face:8D', 1234, 0, ifindex)  # Note capital 
letter `D`.

is meant to trigger getting the IPv6 zoneinfo based on ifindex.

AIX does have a routine to strip zoneinfo off an IPv6 address, but the 
getnameinfo() and getaddrinfo() do not support this.

I can create a new issue specifically for IPv6 zone id issue, or I can add a PR 
here. 

Please advise (the PR is merely adding "skipUnless" logic to test_socket.py.

ERROR: test_getaddrinfo_ipv6_scopeid_symbolic

[issue34397] remove redundant overflow checks in tuple and list implementations

[Tim Peters]

Tim Peters  added the comment:

I agree there's pointless code now, but don't understand why the patch replaces 
it with mysterious asserts.  For example, what's the point of this?

assert(Py_SIZE(a) <= PY_SSIZE_T_MAX / sizeof(PyObject*));
assert(Py_SIZE(b) <= PY_SSIZE_T_MAX / sizeof(PyObject*));

The invariant that needs to be maintained is that the number of elements is no 
larger than PY_SSIZE_T_MAX, so the _relevant_ thing to assert is:

assert(Py_SIZE(a) + Py_SIZE(b) <= PY_SSIZE_T_MAX);

That in turn cries out for an explanation of why it must be true.  The asserts 
actually in the patch are part of that explanation, but on their own appear to 
be coming from Mars.  They're missing the conclusion, and rely on further 
unstated subtleties.

Suggest adding a comment where the structs are defined, like:

"""
Note:  Python's memory allocators return at most PY_SSIZE_T_MAX bytes.  
Therefore a vector of PyObject* can contain no more than PY_SSIZE_T_MAX / 
sizeof(PyObject*) elements.  In particular, a PyObject* consumes at least 2 
bytes, so a vector can contain no more than PY_SSIZE_T_MAX / 2 elements.  Code 
freely relies on that.

#if SIZEOF_VOID_P < 2
#   error "size of pointer less than 2 bytes?!"
#endif
"""

[issue34409] Add a way to customize iteration over fields in asdict() for the nested dataclasses

[mkurnikov]

New submission from mkurnikov :

Suppose I have two dataclasses:

@dataclass
class NestedDataclass(object):
name: str
options: Dict[str, Any] = field(default_factory=dict)

@dataclass
class RootDataclass(object):
nested_list: List[NestedDataclass]

I want a dict under the key "options" to be merged in the NestedDataclass dict 
in the dataclasses.asdict(root_dcls_instance). 

For that, according to docs, I need to specify dict_factory= for 
dataclasses.asdict() function. 

The problem is that, according to the implementation, when this function 
"meets" dataclass, there's no way to customize how result dict will be built. 
Dataclass itself is never passed to the function. 

if _is_dataclass_instance(obj):
result = []
for f in fields(obj):
value = _asdict_inner(getattr(obj, f.name), dict_factory)
result.append((f.name, value))
return dict_factory(result)

Yes, I can catch "result" obj (what I did in the end):

def root_dataclass_dict_factory(obj):
if isinstance(obj, list):
dataclass_dict = dict(obj)
if 'options' in dataclass_dict:
dataclass_dict.update(dataclass_dict.pop('options'))

return dict(obj)

The problem is that type of the dataclass is lost for the list, and if by any 
chance later I'll have "options" key in the RootDataclass, there's no way for 
me to distinguish between them cleanly. 

Other solution is to iterate over the RootDataclass dictionary, follow the path 
to the NestedDataclass and change dictionary there, but it even uglier. 

Would be nice to be able to somehow hook into the field traversal of the 
dataclass instance.

[issue34370] Tkinter scroll issues on macOS

[Kevin Walzer]

Kevin Walzer  added the comment:

I just committed http://core.tcl.tk/tk/info/26a029b4a88ff97f, which fixes the 
scrolling issue in Tk. Running the test scripts here indicate the behavior is 
now correct; clicking several pixels below the bottom part of the scroll button 
causes the scroll to jump, instead of smoothly scrolling. (One must click the 
scroll button directly for smooth scrolling, which is the expected behavior.) 
The fix involved removing support for a small scroll button variant, which was 
causing the confusion; by sticking with a single variant, the normal size 
scroller, the behavior is correct and consistent.

[issue34406] Typo in documentation

[Ammar Askar]

Ammar Askar  added the comment:

For what its worth, window's reg command also makes a distinction between the 
registry key and value:


C:\Users\ammar>reg.exe QUERY HKLM\Software\Microsoft\.NETFramework\Enable64Bit
ERROR: The system was unable to find the specified registry key or value.

C:\Users\ammar>reg.exe QUERY HKLM\Software\Microsoft\.NETFramework /V 
Enable64Bit

HKEY_LOCAL_MACHINE\Software\Microsoft\.NETFramework
Enable64BitREG_DWORD0x1


Maybe it can just be phrased as something like, "set the registry value 
LongPathsEnabled in 
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem"
