[issue29690] no %z directive for strptime in python2, doc says nothing about it

[Mathieu Dupuy]

New submission from Mathieu Dupuy:

➜  ~ cat dt.py 
from datetime import *
dt = datetime.strptime('+1720', '%z')
print(dt)
➜  ~ python2 dt.py 
Traceback (most recent call last):
  File "dt.py", line 2, in 
dt = datetime.strptime('+1720', '%z')
  File "/usr/lib/python2.7/_strptime.py", line 324, in _strptime

ValueError: 'z' is a bad directive in format '%z'
➜  ~ python3 dt.py
1900-01-01 00:00:00+17:20

We should either mention it in doc, either cherry-pick the code from python3

[issue29679] Add @contextlib.asynccontextmanager

[Nick Coghlan]

Nick Coghlan added the comment:

In the specific case of contextlib, most of the APIs should be able to 
transparently support async/await without negatively impacting their 
synchronous behaviour, so after the python-dev discussion, I think one module 
with separate sync and async test suites is a good way to go for contextlib 
specifically: 
https://mail.python.org/pipermail/python-dev/2017-March/147520.html

However, as noted in that message, I *don't* think we can conclude that's going 
to be the right answer for the standard library in general - for many modules, 
a separate a or aio published via PyPI and potentially 
considered for stdlib inclusion later is going to make more sense.

[issue28129] assertion failures in ctypes

[Oren Milman]

Oren Milman added the comment:

The fix for issue #25659 already replaced the assertions in
CDataType_from_buffer and CDataType_from_buffer_copy with if statements (my
bad for missing that issue when I opened this one).
In addition, that fix added some tests, so I also added some, and created a
pull request.

I run the test module again, and on my Windows 10, the same tests failed with
and without my patches. However, on my Ubuntu 16.04 VM, none of the tests
failed.

[issue29594] implementation of __or__ in enum.auto

[Marc Guetg]

Marc Guetg added the comment:

@ethan, didn't know about aenum, thanks for showing it to me. However it 
doesn't seem to support the behavior I'm after (or I'm doing something wrong)

import aenum

try:
class Foo(aenum.Flag):
a = aenum.auto()
b = a | aenum.auto()
except Exception as err:
print(err)

try:
class Bar(aenum.Flag):
a = aenum.auto()
b = aenum.auto() | a
except Exception as err:
print(err)

results in 
unsupported operand type(s) for |: 'int' and 'auto'
exceptions must derive from BaseException

where the latter might be a bug in the implementation.


I do realize that I'm stuck with this for the moment. My motivation with 
opening this thread was that I was wondering if such a feature would be 
worthwhile for the community. In case there is interest in this feature I would 
try to run the unit test and follow all the steps to try to push it through. 
However I save myself the work in case the community decides that the 
implementation is not worth it. Which would also be fine with me, as I monkey 
patched it for my code - so no problem on my end.

[issue29689] Asyncio-namespace helpers for async_generators

[Codey Oxley]

New submission from Codey Oxley:

Expanding an async_generator to any container-type currently makes you do an 
async-for loop/comprehension. There are some third-party libs (aitertools) that 
have helpers but it would be nice for this to be upstream for list, tuple, 
dict, set, etc.

Usage might be:

expanded: List[int] = await asyncio.list(gen())

[issue9303] Migrate sqlite3 module to _v2 API to enhance performance

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

> sqlite3_open_v2 - 2007-09-04 (3.5.0) alpha
> sqlite3_prepare_v2 - 2007-01-04 (3.3.9)
> sqlite3_close_v2 - 2012-09-03 (3.7.14)

There are compile-time checks for supporting SQLite older than 3.2.2.

I think it is better to use the preprocessor rather of autotools for 
conformance with the rest of code.

> What should I do for this to work on windows?

On Windows manually written PC/pyconfig.h is used rather of generated by 
configure pyconfig.h. If you change pyconfig.h, you should update PC/pyconfig.h 
too. But I think this is not needed in this case. Just use 
SQLITE_VERSION_NUMBER.

[issue29687] smtplib does not support proxy

[Rares Vernica]

New submission from Rares Vernica:

smtplib does not support connections through a proxy. The accepted workaround 
is something like:

```
import smtplib
import socks

socks.setdefaultproxy(socks.PROXY_TYPE_SOCKS4, proxy_host, proxy_port)
socks.wrapmodule(smtplib)

smtp = smtplib.SMTP()
```

The side-effects of `socks.wrapmodule` impact other libraries which don't need 
to use the proxy, like `requests`. See here for a disucssion

[issue29686] Unittest - Return empty string instead of None object on shortDescription()

[Vinícius Dantas]

New submission from Vinícius Dantas:

I have been browsing around the unittest standard library, and I realized that 
TestCase's shortDescription() method at lib/pythonX.X/unittest/case.py returns 
None when the there is no docstring on the test that is running.
As shortDescription() should obviously return a string, I would recommend 
returning an empty string instead of None when no docstring is found.
This came to mind when I was using testscenario package, which only displays 
the scenarioname when shortDescription() returns something but None.
When we are starting from scratch a test suite, docstrings are left for another 
stage, when we have running (probably failed, if we are TDDing) unittests.
Last yet not least, I am sure it's a good practice to avoid returning None, 
which forces None-checks, returning empty strings, lists, objects of the return 
type expected from that function.

[issue29302] add contextlib.AsyncExitStack

[Yury Selivanov]

Yury Selivanov added the comment:

Looking at the code: we don't need to use iscoroutinefunction at all.  If we 
had separate methods for sync and async context managers, you can store the 
flag if a function is async or sync along with it.

So _exit_callbacks should store tuples `(is_async, cb)`, instead of just `cb`.

asyncio.iscoroutinefunction differs from inspect.iscoroutinefunction a little 
bit to support asyncio-specific debug coroutine wrapper functions.  We should 
avoid using any version of iscoroutinefunction here.

[issue29302] add contextlib.AsyncExitStack

[Yury Selivanov]

Yury Selivanov added the comment:

Alexander, 

You don't need asyncio.isocoroutinefunction. Please use 
inspect.iscoroutinefunction and inspect.iscoroutine.

Nick,

I'm +1 to have a separate class AsyncExitStack.

> - assume everything passed to it is a coroutine or an async context manager 
> by default

I would add a separate set of methods prefixed with 'a' to handle async context 
managers.

> - always require close() to be called via await

I'd only have one coroutine 'aclose()' that would internally close sync and 
async context managers in the right order.

> - either add synchronous variants of the default-to-async methods 
> (`enter_context_sync`, `push_sync`, `callback_sync`), or else make them 
> auto-adapt to handle both synchronous and asynchronous inputs

I'd use the 'a' prefix. We use it already to name magic methods: __aenter__, 
__aexit__, __aiter__.

> - rather than using `iscoroutinefunction`, instead always invoke callbacks 
> with await, and wrap synchronous callbacks supplied using the above methods 
> in simple one-shot iterators

I'd favour a more explicit approach: separate methods for handling sync and 
async.

Also, speaking about asyncio dependancy -- we shouldn't have it. Using 
asyncio.iscoroutinefunction is unnecessary, inspect.iscoroutinefunction should 
be used instead.

As I said in [1], I think asynccontextmanager and AsyncExitStack should be 
framework agnostic and thus stay in the top level contextlib package.

IMO AsyncExitStack should not be dependent on asyncio, and if it is it means we 
would need to tweak its design to make it not to.  I'll take a look at the

[issue29680] gdb/libpython.py does not work with gdb 7.2

[Alexander Belopolsky]

Alexander Belopolsky added the comment:

Victor, the gdb commit that you mentioned introduced gdb.GdbError which is 
different from gdb.error. [1]  The correct commit is 
621c83642d17cf523c20f55f2ed945a7ec95ea6a. [2]

[issue29410] Moving to SipHash-1-3

[STINNER Victor]

STINNER Victor added the comment:

This issue is an optimization, but I still don't see any significant speedup 
:-) Would it be possible to write at least one microbenchmark showing a 
speedup? Maybe hash()?

[issue9303] Migrate sqlite3 module to _v2 API to enhance performance

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

Is detection in the configure script needed? What are SQLite versions in which 
_v2 APIs were added? What is minimal supported SQLite version?

Don't forget about Windows where autotools are not used.

[issue29640] _PyThreadState_Init and fork race leads to inconsistent key list

[Petr Viktorin]

Petr Viktorin added the comment:

Here is a proof of concept patch from Jaroslav Škarvada. It fixes the problem 
by holding the mutex used for PyThread_create_key while forking.

To make it more than PoC it needs adding _PyThread_AcquireKeyLock and 
_ReleaseKeyLock (similar to _PyImport_AcquireLock() etc.) and calling those.  
Other than that, does this approach look reasonable?

[issue29677] 'round()' accepts a negative integer for ndigits

[Vedran Čačić]

Vedran Čačić added the comment:

This is one of those things that show Python being extremely consistent within 
itself. Of course, docs should be clarified if needed, but the feature is 
desirable and useful.

[issue29684] Minor regression in PyEval_CallObjectWithKeywords()

[INADA Naoki]

New submission from INADA Naoki:

This issue is spin off issue29548.

PyEval_CallObjectWithKeywords(PyObject *func, PyObject *args, PyObject *kwargs)
should raise TypeError when kwargs is not dict.
But after this commit [1], assert(PyDict_Check(kwargs)) can be called when 
args==NULL.

[issue29414] Change 'the for statement is such an iterator' in Tutorial

[Marco Buttu]

Marco Buttu added the comment:

> I don't see this point. The other section titles are not about
> loops. The preceding chapter introduces while loops as a loop,
> not a statement, and this chapter talks about while and for
> loops further down the page.

What I mean is that currently in every section (of this chapter) about a 
statemet, the statement is qualified as "statement": "if Statements", "for 
Statements", "pass Statements", and "break and continue Statements, and else 
Clauses on Loops". The last one is not an exeption, bacause we have already 
introduced for and while, and writing "break and continue Statements, and else 
Clauses on for and while statements" IMO is redundant. 

I like the current structure of titles, because IMO helps beginners to better 
classify things (statements, functions, ...), and it is not clear to me the 
objective motivation for changing "for Statemets" to "for Loops", breaking the 
structure given by the original author.

[issue29683] _PyCode_SetExtra behaviour wrong on allocation failure and after realloc

[Brian Coleman]

New submission from Brian Coleman:

On PyMem_Malloc failure, _PyCode_SetExtra should set co_extra->ce_size = 0.
On PyMem_Realloc failure, _PyCode_SetExtra should set co_extra->ce_size = 0.
On PyMem_Realloc success, _PyCode_SetExtra should set all unused slots in 
co_extra->ce_extras to NULL.

I will add a GitHub PR for this shortly.

[issue29302] add contextlib.AsyncExitStack

[Alexander Mohr]

Alexander Mohr added the comment:

Thanks for the feedback Nick! If I get a chance I'll see about refactoring my 
gist into a base class and two sub-classes with the async supporting non-async 
but not vice-versa.  I think it will be cleaner.  Sorry I didn't spend too much 
effort on the existing gist as I tried quickly layering on async support to 
move on to my primary task.  After doing that I noticed that the code could use 
some refactoring, but only after taking the time deconstructing the impl to 
understand how the code works.

[issue29594] implementation of __or__ in enum.auto

[Ethan Furman]

Ethan Furman added the comment:

aenum 2.0 [1] has been released.  Because it also covers Python 2.7 I had to 
enhance its auto() to cover |, &, ^, and ~ so that Enum classes could be 
properly created.

At this moment your choices are to use odd naming or aenum (with its enhanced 
auto).
