[issue32838] Fix Python versions in the table of magic numbers

[Serhiy Storchaka]

Serhiy Storchaka  added the comment:

I think it is useful to have such table somewhere. It give the impression about 
the history of bytecode and pyc format. There are third-party projects that try 
to support Python bytecode of different versions, they need such table. There 
is a simplified version of this table in PC/launcher.c, it is needed for 
suggesting the Python version by the magic number. And this table is just 
interesting for Python developers, especially if they made the change in the 
bytecode.

[issue32839] Add after_info as a function to tkinter

[Serhiy Storchaka]

Serhiy Storchaka  added the comment:

Note that in the tests for issue32831 you need to use call('after', 'info') if 
you want to backport them.

[issue32839] Add after_info as a function to tkinter

[Serhiy Storchaka]

Serhiy Storchaka  added the comment:

On one side, the first item of the list returned by the Tcl command `after info 
$id` is a name of the Tcl command generated by Tkinter. It is internal, it was 
not exposed to Tkinter users before, and the API for restoring the original 
Python callable is private.

On other side, `after info` can return not only events created by Tkinter, but 
events created by Tcl (either by direct execution of Tcl script, this is still 
can be useful with programming with Tkinter, or created by the Tcl standard 
library or third-party Tcl libraries). In that case a Python callable can't be 
returned.

This is what I was uncertain about. Maybe after_info() should return a Python 
callable if possible, and keep the original result otherwise? This complicates 
its implementation and definition.

TclError is legal and expected. In some methods it is caught, either because 
the method is purposed to be called at widget destroying stage, when the order 
of different cleanup procedures is not specified, and Tcl names can be 
destroyed before destroying Tkinter wrappers, or because the method was 
implemented differently in the past, and catching TclError is needed for 
backward compatibility. after_info() is not the case.

[issue32820] Add bits method to ipaddress

[Nick Coghlan]

Nick Coghlan  added the comment:

Aye, definitely worth a thread on python-ideas. My rationale for suggesting 
something based on the built-in numeric codes is that it makes it 
straightforward for *users* to transfer knowledge from that mini-language.

As far as parsing goes, I was thinking of something along the lines of the 
following naive approach:

typechar = fmt[-1:]
if not typechar or typechar not in ("b", "n", "x"):
return super().__format__(fmt)
prefix, group_sep, suffix = fmt[:-1].rpartition("_")
if prefix and prefix != "#" or suffix:
return super().__format__(fmt)
field_width = self._calculate_field_width(typechar)
return format(int(self), f"{prefix}0{field_width}{group_sep}{type_char}")

[Nick Coghlan]

Nick Coghlan  added the comment:

We still need to the ".0" style temporary variables that are used for argument 
names in the implicitly generated functions, but it's definitely plausible that 
we're not actually using the "_[1]" style hidden variables anywhere anymore.

[issue32756] argparse: parse_known_args: raising exception on unknown arg following known one

[paul j3]

paul j3  added the comment:

This error message is intentional.

In def consume_optional(start_index):

# identify additional optionals in the same arg string
# (e.g. -xyz is the same as -x -y -z if no args are required)

# if the action is a single-dash option and takes no
# arguments, try to parse more single-dash options out
# of the tail of the option string
chars = self.prefix_chars
if arg_count == 0 and option_string[1] not in chars:
action_tuples.append((action, [], option_string))
char = option_string[0]
option_string = char + explicit_arg[0]
new_explicit_arg = explicit_arg[1:] or None
optionals_map = self._option_string_actions
if option_string in optionals_map:
action = optionals_map[option_string]
explicit_arg = new_explicit_arg
else:
msg = _('ignored explicit argument %r')
raise ArgumentError(action, msg % explicit_arg)

In other words, it doesn't just split off that extra character and add it to 
'argument_strings' for further handling.

Either 'b' is an argument for the '-a' flag or it is a '-b' flag itself.  It 
can't be a positional or extra.

[issue32841] Asyncio.Condition prevents cancellation

[Nathaniel Smith]

Nathaniel Smith  added the comment:

Interesting case! This is super subtle. I think the patch is correct though.

(In Trio this is one of the cases where we use shielding: 
https://github.com/python-trio/trio/blob/f48d8922dfe2118bfaaf9a85f2524e58146ba369/trio/_sync.py#L749-L752
 . But asyncio.shield has different semantics -- it still delivers the 
CancelledError to the caller, which is no good in this case.)

[issue32839] Add after_info as a function to tkinter

[Terry J. Reedy]

Terry J. Reedy  added the comment:

I am in favor of exposing all of tk where it makes sense to do so, and I think 
it does here.

After 'translating' the tk after_info entry into tkinter-ese, I would expect 
and want that
  root.after_info(root.after(f, 10))[0] is f
be true.  the same as would be true of the tcl equivalent. (This could even be 
a test.)  It appears that the current patch instead returns a (python) 
reference to the tcl wrapper of f.  The fact that python callbacks get wrapped 
as tcl callbacks is currently transparent to tkinter users and should remain so.

Serhiy, I presume that this is what you were uncertain about.  I am presuming 
above that f can be recovered.

Returning the function kind as 'timer' or 'idle' is fine. In other contexts, an 
enumeration would be a possibility, but this does not seem to fit tkinter.

I presume a bad id results in TclError.  Do other tkinter functions allow 
TclError to propagate?  My impression is no.  If so, it should be replaced here 
in a way consistent with other tkinter practice.

[issue32841] Asyncio.Condition prevents cancellation

[Bar Harel]

New submission from Bar Harel :

Hey guys,

A week after a serious asyncio.Lock bug, I found another bug that makes 
asyncio.Condition ignore and prevent cancellation in some cases due to an 
"except: pass" which tbh is a little embarrassing.

What happens is that during the time it takes to get back a conditional lock 
after notifying it, asyncio completely ignores all cancellations sent to the 
waiting task.

le_bug.py: Contains the bug
le_patch.diff: Contains a very simple fix (will send a pull on Github too)
le_meme.jpg: Contains my face after debugging this for 4 hours

Yuri, I hope you didn't miss me during this week ;-)

[issue32840] Must install python 3.6.3 when 3.6.4 already installed

[J. Morton]

New submission from J. Morton :

Got a 0x8070666 "Setup Failed - another version installed" popup message when 
installing 3.6.3 with 3.6.4 and 3.5.1 already installed (all are "just for me" 
installs). The problem is independent of word length.
It should be possible to install any/every earlier version (within reason) 
provided the earlier version is "virtualized" by being placed in it's own 
folder (which I was what I was doing). 
Please accomodate this capability as it is often needed to support users using 
earlier versions of Python. 

Environment: 64 bit Win7 Enterprise SP1 on a IM controlled machine. Possible 
red herring: IM recently upgraded java on this machine to "1.8.0_151".  32 and 
64 bit versions of all releases are installed on this machine.

[issue32795] subprocess.check_output() with timeout does not exit if child process does not generate output after timeout

[Fangyi Zhou]

Fangyi Zhou  added the comment:

As far as I have discovered, the bash process is killed by after the timeout. 
Presumably the pipe is still open due to the sleep process, so in order to 
retrieve any output from stdout/stderr, the read waits on the pipe, hence 
leading to timeout not respected.

We can fix this issue in 2 ways 
(1) kill process tree when timeout happens
(2) force closing the pipes after timeout, but this will leave the 
sub-processes detached and it will be kept running

I don't know which way is better, hopefully someone with more knowledge can 
engage in the discussion.

[issue20632] Define a new __key__ protocol

[Cheryl Sabella]

Cheryl Sabella  added the comment:

Thanks, Nick.

When I first came across this issue, I thought that dataclasses would take care 
of what you wrote below, but after looking at the original discussion on 
python-dev, I thought the problem was ordering None within a comparison with 
None being a valid value in SQLite.

For example,
>>> a = [1, None, 'a']
>>> b = [1, 5, 'b']
>>> a == b
False
>>> a < b
Traceback (most recent call last):
  File "", line 1, in 
TypeError: '<' not supported between instances of 'NoneType' and 'int'

[issue31562] snakebite.net is not available

[Trent Nelson]

Trent Nelson  added the comment:

Unfortunately the host backing blackhole.snakebite.net and 
whitehole.snakebite.net is no longer available.  I still think the underlying 
test is valuable, though -- are there any PSF boxes/containers that could 
fulfill this role?

(I used pf on FreeBSD to set up the two firewall rules: 
https://github.com/python/cpython/blob/master/Lib/test/test_timeout.py#L183.  
If a new box were to be sourced I presume it would be a Linux instance, so the 
rules would need to be ported to whatever the Linux firewall on the box is.)

[issue32839] Add after_info as a function to tkinter

[Cheryl Sabella]

Cheryl Sabella  added the comment:

I was working on the tests for issue32831.  One of the methods was `__del__` 
which made sure timer events were canceled with `after_cancel`.  In the test, 
to assert that the after events no longer existed after calling `__del__` and 
after reading the Tcl documentation for `after`, I tried to call `after_info` 
but it didn't exist. So I added a call to `self.tk.call('after', 'info', id)` 
directly to assert that the after events no longer existed.

I don't know if there is a general need to know whether timer or idle events 
exist, but this command gives that information.

[issue32820] Add bits method to ipaddress

[Eric V. Smith]

Eric V. Smith  added the comment:

If you don't recognize the format string, you want to fall back to:

return super().__format__(fmt)

Since that will call object.__format__, it will generate an error if fmt is not 
the empty string, which is what it does currently for IP addresses.

As far as parsing the format specifier, you're on your own. _pydecimal.py has a 
version that parses something very similar (or maybe identical) to the 
mini-language used by float, int, str, etc. But I'm not sure you need to go 
that far. Since you can define any format spec you'd like, you're not 
constrained to the mini-language used by the built-in types (see datetime for 
an example, which just calls strftime). I think the _pydecimal.py approach of 
using a regex isn't bad, but you might want to delay loading re until 
__format__ is called.

Before you go too far down this path, I think this should probably be taken to 
python-ideas to hash out what the format spec for IP addresses would look like, 
or even if this is a good idea at all. I'm generally supportive of handling it 
through __format__().

[issue32820] Add bits method to ipaddress

[Eric Osborne]

Eric Osborne  added the comment:

This is an interesting idea.  I hacked together something to handle IPv4
and pushed it to the repository.  It works, but I'm afraid it may be kinda
ugly.  Do you have any examples of good, pythonic ways to parse the format
string or otherwise extend __format__?  I didn't see many examples in
stdlib, and the ones I did got pretty deep into it pretty quick.

Test output:

IPv4 address 1.2.3.4
format: b
0001001000110100

format: n
0001001000110100

format: x
01020304

format: _b
_0001__0010__0011__0100

format: _n
_0001__0010__0011__0100

format: _x
0102_0304

format: #b
0b0001001000110100

format: #n
0b0001001000110100

format: #x
0x01020304

format: #_b
0b_0001__0010__0011__0100

format: #_n
0b_0001__0010__0011__0100

format: #_x
0x0102_0304

Thanks!

[issue32839] Add after_info as a function to tkinter

[Cheryl Sabella]

New submission from Cheryl Sabella :

In tkinter, after_cancel has a call to after info:
data = self.tk.call('after', 'info', id)

Since this is a supported command, there should be a function to access it 
directly.

[issue32838] Fix Python versions in the table of magic numbers

[Serhiy Storchaka]

New submission from Serhiy Storchaka :

All changes to the magic number in Lib/importlib/_bootstrap_external.py are 
attributed with 3.7a0. But they were made at different stages.

There is also inconsistency in specifying Python version for older changes. 
Some authors specify the first Python version after bumping the magic number 
(i.e. the version that was released with this magic number). Others specify the 
Python version after which the bumping was made. I think the former is correct.

The proposed PR fixes Python versions and adds issue numbers if known. I have 
tracked only changes in Python 3.x.
