I'm not sure how exposing all private methods spiraled out of this issue. We 
haven't discussed documenting the low-level methods you just exposed Andrew. 
IMO this should be reverted.

[issue47167] Allow overriding future-task compliance check in asyncio

[Yury Selivanov]

Yury Selivanov  added the comment:

Sorry, I don't like the committed change and I think it should be reverted.

Futures and Tasks have a documented `get_loop()` method which simply should be 
called by Task machinery, without the need to expose (and document) private 
methods.

Right. There used to be an API called "EWS", but that's no longer
available (at least on the servers I've dealt with). Instead, there's
a REST/JSON api that's used by the outlook web client.

There are a few email clients (that I'm aware of) that have figured
out how to use that API:

 Hiri

    (now abandoned) which stopped working for
   me yesterday.

 Webmail for OWA

   https://play.google.com/store/apps/details?id=smtb.owa Android app.

 OWL Thunderbird plug-in

   This is working nicely for me.

There is an older Thunderbird plugin (by the developers of OWL) that
used the EWS protocol (but not OWA) called ExQuilla.

I think that the protocol used by Outlook is MAPI/RPC or MAPI/HTTP. I
believe that Evolution used to be able to use that protocol, but from
what I've read it only works with very old versions of Exchange. For
newer Exchange servers, Evolution supports EWS, but the servers I've
dealt with over the past few years didn't seem to support EWS. [Though
I haven't tried for a while.]

I haven't used GTK in ages and ages, but I do still have a tkinter program
that I drag out every now and then when my wrists start acting up. After
opining about this on the PyIdeas discuss forum, I spent a few minutes and
came up with a simple AsyncTk subclass of tkinter.Tk. Here's its hello
world:

https://gist.github.com/smontanaro/5e12c557602a76c609e46ca59387ad1c

I modified my activity watcher to use it:

https://github.com/smontanaro/python-bits/blob/master/src/watch.py

A few warnings:

   1. copy/paste reuse of that AsyncTk class
   2. the code is a mess (it's probably 20-25 years old, I make no
   apologies for the mess)
   3. as of about an hour ago it now uses pynput to watch for mouse/kbd
   watching

So, Tk+asyncio turns out to be fairly easy to do, at least for simple stuff.

From what I found, M$ doesn't consider OWA to be an API... It expands
to "Outlook Web App", period, (and more recently is called "Outlook for the
Web").

That would explain why there is no documentation of an "API"... I get
the impression that any so-called API programs have had to reverse engineer
(maybe using things like WireShark) the HTTP communication.

I'm trying out Thunderbird with an OWA plugin

https://www.beonex.com/owl/

and it's working very nicely. There are some quirks in Thunderbird
that I'm still tring to figure out, but I have the same issues if it
were using IMAP/SMTP.

Using the _OWA_ protocol? When our server switched from EWS to OWA, I
could no longer get it to work.

I used Davmail in the past when the server supported EWS. AFAICT, it
does not work with the current server. If you look at the Exchange
protocols listed at http://davmail.sourceforge.net/gettingstarted.html,
OWA is not one of them:

 * O365Modern Office 365 modern authentication (Oauth2)
 
 * O365Interactive Office 365 with interactive browser window, not
   available in headless mode (OpenJFX required)

 * O365Manual Office 365 with interactive dialog, not available in
   headless mode
 
 * O365 Office 365 EWS mode
 
 * EWS Exchange 2007 and later
 
 * WebDav Exchange 2007 and earliear WebDav mode
 
 * Auto WebDav mode with EWS failover

Have you used it with OWA as the protocol?

No, outlook.com is a Microsft web hosting service.

OWA is an HTTP-based API suspport by MS Exchange server.

I don't want to connect to Outlook.com. I want to connect to an
Exchange server that doesn't not have IMAP, POP3, or SMTP enabled.

[issue39090] Document various options for getting the absolute path from pathlib.Path objects

[EZ]

EZ  added the comment:

First, I hope we all agree:
'C:\Windows' and '/usr/bin' == absolute path
'Windows' and 'bin' == relative path
'C:\Program Files' and '/bin' == absolute path
'C:\Windows\..\Program Files' and '/usr/../bin' == relative path

It is very confusing between these two, but despite claims otherwise, 
absolute() does not work as expected. However, to sum up the findings below: 
* absolute() fails to resolve paths with relative steps (esp "..") but will 
always add the dir structure even if the file doesn't exist.
* resolve() will always give an absolute path.
** unless the file doesn't exist -- 
** unless unless the path includes a '..'! 
* There's also a related problem with is_absolute() being incorrect with 
relative paths (such as '..'), which usually results in it saying 
absolute().is_absolute() is True when it is obviously False.

Done on Windows 10, python 3.9.5

>>> ini
WindowsPath('desktop.ini/..')
>>> ini.resolve().is_absolute()
True
>>> ini.absolute()
WindowsPath('C:/Users/zim/Downloads/desktop.ini/..')
>>> ini.absolute().is_absolute()
True

This second should not be True, there is a trailing '..' not resolved by 
absolute()

Now let's create a truly messy path:
>>> ini.resolve()
WindowsPath('C:/Users/zim/Downloads')
>>> ini = ini / "ntuser.ini"
>>> ini.exists()
False
>>> ini.resolve()
WindowsPath('C:/Users/zim/Downloads/ntuser.ini')
>>> ini = ini / "../ntuser.ini"
>>> ini.exists()
False
>>> ini.resolve()
WindowsPath('C:/Users/zim/Downloads/ntuser.ini')
>>> ini = ini / "../../ntuser.ini"
>>> ini.resolve()
WindowsPath('C:/Users/zim/ntuser.ini')
>>> ini.exists()
True
>>> ini.absolute()
WindowsPath('C:/Users/zim/Downloads/desktop.ini/../ntuser.ini/../ntuser.ini/../../ntuser.ini')
>>> ini.absolute().is_absolute()
True

absolute() not only doesn't give an absolute path, but is_absolute() is somehow 
ok with that.

Now a file that doesn't exist:
>>> mike = Path("palin.jpg")
>>> mike.resolve()
WindowsPath('palin.jpg')
>>> mike.resolve().is_absolute()
False
>>> mike.absolute()
WindowsPath('C:/Users/zim/Downloads/palin.jpg')
>>> mike.absolute().is_absolute()
True

Finally, absolute() is right about the right thing, but resolve() is not 
terribly wrong. is_absolute() is correctly False here (for once). 

The problem is that the after a resolve() call, a Path object can still be used 
to create a file (good), but if resolve() is used before file creation, then 
the full path will not be there as should be expected (bad). This seems like a 
bug with resolve()

What if a file is non existent AND relative? Things get more confusing.

>>> badrel = Path('../circus.jpg')
>>> badrel
WindowsPath('../circus.jpg')
>>> badrel.absolute()
WindowsPath('C:/Users/zim/Downloads/../circus.jpg')
>>> badrel.resolve()
WindowsPath('C:/Users/zim/circus.jpg')
>>> badrel.exists()
False

So, absolute() still acts like the normal trash fire it is with relative paths, 
but what's this, resolve() actually gives an absolute path?!

I should note resolve() only behaves unpredictably on Windows. It correctly 
resolves non-existent files no matter what on macOS and Linux (caveat: my linux 
test was done with python 3.6). However, absolute() always fails to distill 
paths with relative steps regardless of OS.

So, it seems clear:
Bug 1: resolve() should work the same with non-existent files with incomplete 
paths on Windows as it does on *nix platforms, as it does on Windows when 
handling existent files and non-existent ones with parent path notation.
Bug 2: Obviously if absolute() is supposed to be in the lib, it should be 
documented, and it likely should be distinct from resolve(), but most of all: 
it should return actual absolute paths! If these cannot be fulfilled, it should 
be set to be deprecated (after resolve() is fixed, hopefully)
Bug 3: is_absolute() should actually detect absolute paths, instead it seems to 
report True if the path contains a root starting point, but ignores relative 
changes in between. (this issue exists on all three major OSs)

[issue44159] mimetypes - "strict" on Windows

[Mark Dong]

Mark Dong  added the comment:

Hi, 

I want to follow up on this:

On Linux (Ubuntu 20.04.4 LTS), the module also loads everything it finds in the 
registries (a.k.a, entries in the "knownfiles" variable) in "strict" mode, even 
though some of them aren't registered in IANA. (I'm assuming that "registered 
in IANA" means everything in here only: 
https://www.iana.org/assignments/media-types/media-types.xhtml)

For example, ".com" is recognized as having mimetype 
"applications/x-msdos-program". This becomes problematic when an unparsed URL, 
such as "http://abc.efg/hij.html#http://abc.com;, is fed into guess_type.

I'm wondering if we should make the documentation clearer and state that 
"strict=True" means using IANA registered types along with the types found on 
the machine, it seems like this is the expected behavior based on the comments 
in "def _default_mime_types()", or we should actually move everything other 
than IANA registered types out of strict mode.

Best regards,
Mark

I can recommend davmail as a workaround:

http://davmail.sourceforge.net/

Davmail converts OWA into regular mail protocols like POP3, IMAP, SMTP.
You can use any email/calender client (I've used thunderbird) and most
of it worked well.

Davmail is written in Java, not Python, but basically this should not
matter if you only use it.

Re: Exchange OWA using Python?

Is anybody aware of any Python code for the Exchange OWA protocol/API?

The OWA e-mail client I've been using has stopped working. It was a
commerical Python application named Hiri, wich has been abandoned by
the developer.

So, for now, I'm stuck with the OWA web client. It's clumsy and
everything takes 3X as long to accomplish as it would with a real
e-mail client, but I can survive with it if I have to. 


I can recommend davmail as a workaround:

http://davmail.sourceforge.net/

Davmail converts OWA into regular mail protocols like POP3, IMAP, SMTP. 
You can use any email/calender client (I've used thunderbird) and most 
of it worked well.


Davmail is written in Java, not Python, but basically this should not 
matter if you only use it.

[issue47151] subprocess fails when used as init, vfork() returns EINVAL if PID=1

[Gregory P. Smith]

Gregory P. Smith  added the comment:

Thanks. I had wondered if this was really a pid=1 restriction or not, but I 
could definitely imagine kernel scenarios where vfork is simply forbidden 
regardless. There are a variety of policy mechanisms in kernels, mainline Linux 
or not, that _could_ do that kind of thing.

As much as I'd like to expose that the fallback happened, emitting to stderr 
isn't friendly and using warnings from this code is complicated so I'm inclined 
to keep the silent fallback on failure simple as is until someone can 
demonstrate of it causing a practical problem.

Outside of unusual configurations, if this were ever happening when it is not 
expected, people observing low subprocess performance could strace and witness 
the vfork syscall failure.

I'll merge once our CI is happy.

Done. Feel free to push directly to the repo, and bear in mind that changes may

(ahem... mostly... we've gotten it wrong before). Fourth field of the version 
number is our private one, so it gets incremented if we need to patch or 
re-release something, rather than changing the tag, unless we really do want to 
force change the tag.

Feel free to reach out if you have any questions. Otherwise, SQLite updates are

I think you're referring to the fact that Ubuntu releases a new stable
version every 6 months, while Debian every 2 years. This is true, but
Ubuntu also releases a LTS every 2 years. You can install a LTS and
change the options so you'll update the system only where a new LTS is
coming out. Furthermore you're not forced to upgrade, you can do it
when the LTS comes to the end.

On the other hand, you can live on the edge with Debian too. You can
install an unstable branch.

Furthermore, there's the company factor. According to Google, Debian
has about 1k devs, while Ubuntu only about 250. But these devs work
full time on Ubuntu and they are paid for. Not sure this is not an
important point. For what I know, historically the distros with the
reputation to be more stable are distros maintained by companies, Red
Hat and Gentoo for example.

About stability and security, I can't disagree. But I suppose the
people that use the unstable version of some Linux distro are useful
for testing and reporting bugs, also security one. So they contribute
to the stable versions, and I think we have to be grateful to these
"pioneers".

I prefer to use the -u when I run the output of python into the.

python -u script.py | tee script.log

And use py -u on windows.

This has always been the case with Debian (they even created a special
repo for packages where this wasn't feasible, like browsers (which
typically update every few weeks and are too large for the security team
to backport security fixes).

In my experience it's also the case for Ubuntu (see the version numbers
I posted).

It also was the case for Redhat, but they seem to have switched to a
rolling updates model some time ago. I'm not sure how they handle that
now.

Is there a question in there somewhere?

Crystal ball is hazy...

However... Note that once you encode the Unicode literal, you have a
BYTE string. There are 12 bytes in that binary -- it is NOT considered
Unicode at that point (only when you decode it with the same CODEC will it
be Unicode).

Temporally disabling buffering

[Cecil Westerhof via Python-list]

In Python when the output of a script is going to a pipe stdout is
buffered. When sending output to tee that is very inconvenient.

We can set PYTHONUNBUFFERED, but then stdout is always unbuffered.

On Linux we can do:
PYTHONUNBUFFERED=T script.py | tee script.log

Now the output is only unbuffered for the current run and buffered for
other runs where the output goes to a pipe.

That is is what I partly mean.

Debian is very big on security and stability. Most people think that
Ubuntu is that also, because it is based on Debian. But Ubuntu wants
also provide the newest versions of software and this will affect the
stability and security negatively.
Even for a desktop I find stability and security more important as the
newest versions. That is why I even for the desktop use Debian.
Personally I find it strange that people choose newest versions over
stability and security for a server.

Grégory: that will fix this issue, but what I really need is some of the other 
changes, like moving the getaddrinfo logic into a separate route (connect).

[Python-announce] Wing Python IDE version 8.3 has been released

[Wingware]

Wing 8.3 improves remote development by allowing it to work without an 
SSH agent or command line OpenSSH or PuTTY configuration. This release 
also supports forwarding of the SSH agent to the remote host, allows 
blocking access to any SSH agent, improves analysis of match/case 
statements, avoids reporting spurious exceptions in async def 
coroutines, and makes a number of other improvements to refactoring, 
code reformatting, debugging, and other features.


Details: https://wingware.com/news/2022-03-30
Downloads: https://wingware.com/downloads

== About Wing ==

Wing is a full-featured but light-weight Python IDE designed 
specifically for Python, with powerful editing, code inspection, 
testing, and debugging capabilities. Wing's deep code analysis provides 
auto-completion, auto-editing, code navigation, early error detection, 
and refactoring that speed up development. Its top notch debugger works 
with any Python code, locally or on a remote host, container, or 
cluster. Wing also supports test-driven development, version control, 
Python package management, UI color and layout customization, and 
includes extensive documentation and support.


Wing is available in three product levels:  Wing Pro is the 
full-featured Python IDE for professional developers, Wing Personal is a 
free Python IDE for students and hobbyists (omits some features), and

Exchange OWA using Python?

[Grant Edwards]

Is anybody aware of any Python code for the Exchange OWA protocol/API?

The OWA e-mail client I've been using has stopped working. It was a
commerical Python application named Hiri, wich has been abandoned by
the developer.

So, for now, I'm stuck with the OWA web client. It's clumsy and
everything takes 3X as long to accomplish as it would with a real
e-mail client, but I can survive with it if I have to. [Retirement's
not that far away...] The main problem with the web client is lack of
notification when new mail arrives. Even if you always have a browser
running (I don't), and have a tab that has the OWA client running (I
often don't), notification doesn't seem to work reliably (and when it
does work, it doesn't use the standard linux desktop notification
system).

Back when the Exchange IMAP server was enabled (and I used mutt as my
e-mail client), I wrote a e-mail notifier app in Python/GTK, so I knew
when new mail was waiting.

I've been wondering if it would be possible to do the same thing using
the Exchange OWA API/protocol instead of IMAP?

But, I haven't found any Python support for OWA.  I've found libraries
for the older Exchange EWS API, but AFAICT the Exchange server in
question doesn't support EWS, only OWA.

I've also found a bunch of info for Outlook/REST and Office365/REST,
but I'm pretty sure those won't work either...

[issue47179] pymalloc should align to max_align_t

[STINNER Victor]

STINNER Victor  added the comment:

Objects/obmalloc.c currently relies on the SIZEOF_VOID_P macro:
---
#if SIZEOF_VOID_P > 4
#define ALIGNMENT  16   /* must be 2^N */
#define ALIGNMENT_SHIFT 4
#else
#define ALIGNMENT   8   /* must be 2^N */
#define ALIGNMENT_SHIFT 3
#endif
---

If we want to respect sizeof(max_align_t) alignment, we can compute 
sizeof(max_align_t) in configure and uses the result in obmalloc.c. I expect 
that it's either 16 or 32, so we can maybe just hardcode ALIGNMENT_SHIFT using 
something like: "if == 32 ... #elif == 16 ... #else #error ...".

On x86 (32-bit) Fedora 35, gcc says 48 for sizeof(max_align_t) which is way 
larger than the current alignment to 8 bytes!

[issue47179] pymalloc should align to max_align_t

[STINNER Victor]

STINNER Victor  added the comment:

On my x86-64 Fedora 35, gcc says 32 bytes for sizeof(max_align_t). By the way, 
g++ also says 32 bytes for sizeof(std::max_align_t).

GCC 11.2.1 defines max_align_t as:
---
#if (defined (__STDC_VERSION__) && __STDC_VERSION__ >= 201112L) \
  || (defined(__cplusplus) && __cplusplus >= 201103L)
#ifndef _GCC_MAX_ALIGN_T
#define _GCC_MAX_ALIGN_T
/* Type whose alignment is supported in every context and is at least
   as great as that of any standard type not using alignment
   specifiers.  */
typedef struct {
  long long __max_align_ll __attribute__((__aligned__(__alignof__(long long;
  long double __max_align_ld __attribute__((__aligned__(__alignof__(long 
double;
  /* _Float128 is defined as a basic type, so max_align_t must be
 sufficiently aligned for it.  This code must work in C++, so we
 use __float128 here; that is only available on some
 architectures, but only on i386 is extra alignment needed for
 __float128.  */
#ifdef __i386__
  __float128 __max_align_f128 
__attribute__((__aligned__(__alignof(__float128;
#endif
} max_align_t;
#endif
#endif /* C11 or C++11.  */
---
file: /usr/lib/gcc/x86_64-redhat-linux/11/include/stddef.h

It's not an union but a structure with 2 fields (1 long long, 1 long double). 
The __i386__ macro is not defined on Linux x86-64, so the struct does not have 
the 3rd 128-bit float field.

align.c:
---
#include 
int main() { return sizeof(max_align_t); }
---

Build and run (C):
---
$ gcc align.c -o align && (./align; echo $?)
32
---


align.cpp:
---
int main() { return sizeof(std::max_align_t); }
---

Build and run (C++):
---
$ g++ align.cpp -o align && (./align; echo $?)
32

[issue47182] _PyUnicode_Fini should invalidate ucnhash_capi capsule pointer

[Christian Heimes]

New submission from Christian Heimes :

unicodeobject.c has a static pointer to a unicode name CAPI capsule:

   static _PyUnicode_Name_CAPI *ucnhash_capi = NULL;

The capsule is initialized on demand when the parser encounters a named unicode 
representation like "\N{digit nine}". Once the capsule pointer ucnhash_capi has 
been initialized, it is never reset. Not even a full interpreter shutdown 
invalidates the pointer.

A shutdown of the main interpreter with Py_Finalize() renders the pointer 
invalid. If the interpreter is re-initialized again, the invalid pointer causes 
a segfault. The problem was first discovered by Trey Hunner in 
https://github.com/ethanhs/python-wasm/issues/69

python.js:219 Uncaught RuntimeError: null function or function signature 
mismatch

I can reproduce the issue with pure C code:

[issue47158] logging.handlers.SysLogHandler doesn't get cleaned up properly on exit if it throws an exception

[Grégory Starck]

Grégory Starck  added the comment:

Enji : you can use this then:

```
In [6]: class Fixed(logging.handlers.SysLogHandler):
   ...: def __init__(self, *a, **kw):
   ...: self.socket = None
   ...: super().__init__(*a, **kw)
   ...: def close(self):
   ...: if self.socket is None:
   ...: return
   ...: super().close()
```

that looks to be enough to prevent the issue.

[issue47166] Dataclass transform should ignore TypeAlias variables

[Alex Waygood]

Alex Waygood  added the comment:

I think implementing this would add complexity to the code in dataclasses.py 
(though Eric's the expert!).

For your use case, is it essential that the type alias declaration be inside 
the class scope? Would it be possible for you to simply have the alias 
declaration in the global scope instead?
