[issue28512] PyErr_SyntaxLocationEx() and PyErr_SyntaxLocationObject() always set the offset attribute to None

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

Ah, it was a remnants of backporting to 3.5. Commented-out lines are used in 
3.6. The line above these lines was used in 3.5. Test is passed with both 
variants. I commented out the 3.6 variant, but forgot to remove it (or remove 
old 3.5 variant and keep 3.6 variant). Do you think I should remove commented 
out lines, or left the code as is?

[issue28958] Python should return comperhansive error when SSLContext cannot be created

[Ilya Kulakov]

New submission from Ilya Kulakov:

When SSLContext cannot be created, python raises an SSLError exception with 
"failed to allocate SSL context".

https://hg.python.org/cpython/file/4def2a2901a5/Modules/_ssl.c#l2260

This is completely useless to debug the error. In fact many errors raised from 
_ssl.c are non-helpful.

Python's SSLError should be extended to include comprehensive information about 
OpenSSL's error stack which can be extracted with `ERR_get_error_line`.

[issue26110] Speedup method calls 1.2x

[INADA Naoki]

INADA Naoki added the comment:

> Technically the patch LGTM. But we should find the cause of the regression in 
> some benchmarks.

The benchmark is on Sandy Bridge (Core i5 2400) and I didn't use PGO build.
perf_event reported branch-miss rate increase at cpickle's save function.

I'll rerun benchmark with PGO build. I hope PGO is friendly with CPU branch
prediction, like L1/L2 cache.

Anyway, recent amd64 CPUs have more large branch history.

I'll do them.

[issue25458] ftplib: command response shift - mismatch

[Ivan Pozdeev]

Ivan Pozdeev added the comment:

I tried to fix `urllib' and ultimately failed. In a nutshell, handling of the 
aftermath of an `ntransfercmd' is broken.

Since `ntransfercmd'/`transfercmd' returns a socket, handling of an 
end-of-transmission response is done in independently invoked code - upon the 
socket's close. So, if any other operation on the command connection is 
attempted before that, `ftplib's handling of the session breaks.

The plan to fix follows, but first, some background:

According to 
http://stackoverflow.com/questions/2549829/using-ftplib-for-multithread-uploads 
, FTP actually doesn't, and is not designed to, handle transfers in 
"background". In that you surely can send a further command on the socket, but 
the server won't actually read it until it's done with the transfer.

According to 
http://stackoverflow.com/questions/31560701/ftp-data-connections-reuse , data 
connections cannot be reused.

(RFC959 is vague on both points)

Now, the proposed fix design:

* upon starting a transfer, an FTP object sets a flag, `transfer_in_progress'.
* any public subroutine that would send a further command checks the flag. 
Then, there are a few options:
a) refuse any further commands outright until the user explicitly closes 
the socket (whose close handler would also handle the end-of-transfer response)
b) check the wire for an end-of-transfer response and if it's there, handle 
it and allow the command. Closing the socket may or may not handle the response 
in its own right.
c) allow the command even if there's no end-of-transfer response. Then 
handling of the transfer response is done with the function parsing the 
response for the new command - which will hang until the transfer is complete.
* the code handling the end-of-transfer response clears the flag.

Each option has drawbacks, so I'm not sure which one is the most pythonic.
I would go with b) because it would allow syntax like 
urllib.urlopen(<...>).read() which it does allow for HTTP.

[issue28091] Document PEP 525

[Eric Appelt]

Eric Appelt added the comment:

I believe that I addressed all the comments in the previous review (although 
its always possible I missed something), and have a new patch with the 
improvements and fixes.

I also noticed that in asyncio, loop.shutdown_asyncgens() is a coroutinemethod 
and fixed the markup to reflect that as I previously labeled it a method. The 
example I added here is as suggested, but it differs from the example in PEP525 
in that shutdown_asyncgens() is run in a finally clause, which makes sense to 
me.

When applying the comments to sys.set_asyncgen_hooks() I verified that the 
keywords are optional but it is apparently not keyword only. I couldn't find 
many good examples of referencing source, so you may want to closely check how 
I linked to the shutdown_asyncgens() implementation.

[issue28923] Nonexisting encoding specified in Tix.py

[Terry J. Reedy]

Terry J. Reedy added the comment:

I am a little puzzled as to how a file rename changed the content, but the 
annotation history seems to show that.  Anyway, ...

When I load the file in IDLE 2.7, I get a warning.  I am a bit surprised as 
this is not a proper encoding declaration.  IDLE's re must be a bit loose.

In 3.x, the file starts with

# -*-mode: python; fill-column: 75; tab-width: 8 -*-
#
# $Id$
#

This is all ancient, obsolete, junk specific to some editor.  (The file itself 
not used 4 space indents.) I think it should be removed from all current 
versions.  As near as I can tell, there are no non-ascii chars in the file.

[issue28949] Unable to launch Python interpreter

[Jason R. Coombs]

Jason R. Coombs added the comment:

Before disabling SIP, I found I could use fs_usage to get some visibility into 
fs changes:

sudo fs_usage -w -f filesys | grep aliases.py

To test my understanding of fs_usage, I deleted aliases.py (also confirming 
that triggers the error). When I did so, I noticed something interesting - my 
Dropbox account detected deletion of 34 instances of a file called aliases.py. 
A quick search reveals that I have about 34 virtualenvs created by tox, each of 
which links .tox/python/lib/python3.6/encodings to 
/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/encodings.

Now I'm suspecting that there's a race condition where Dropbox ends up deleting 
the system file. Either that, or there's a buggy piece of code somewhere that's 
deleting encodings/aliases.py (and possibly other files) in one of these 
virtualenvs, causing the file to be deleted in the system.

I'm using Dropbox v16.3.27 
(https://www.dropboxforum.com/t5/Desktop-client-builds/Beta-Build-16-3-27/td-p/197057).

I'll continue to investigate, but I'm becoming increasingly suspicious of this 
being an environmental problem.

New submission from Ram Rachum:

I had this error come up in my code, and because it doesn't use `raise ... 
from` I thought that the second error was unexpected, while in fact it wasn't. 
This patch should fix that.

[issue28933] AC: Accept None as a Py_ssize_t default value

[Julien Palard]

Julien Palard added the comment:

> for just one use case

I don't think that using None in a default argument is "one use case", nor a 
"special case" it's more like a "widly used pattern" that I'd like to make 
simple to implement (also see http://bugs.python.org/issue28754#msg282891).

I'm not sure you're against my idea of accepting None like:

something: Py_ssize_t(c_default="-1") = None

Or you're against my implementation, which I can understand, I'm not a fan of 
modifying getargs.c for this, it may be doable by implementing a new converter 
in clinic.py like "Py_ssize_t_optional", and it may not require more work than 
modifying getargs.c.

But AC is already defining 4 different "default values", counting the "= value" 
from the AC DSL, I'm not sure that adding the "optional" string somewhere make 
any of this clearer, typically what about the semantic difference between:

something: Py_ssize_t_optional()

and

something: Py_ssize_t() = None

So my original idea was to accept "= None" indistinctly of the used type, I 
mean allowing:

something: Py_ssize_t(c_default=…) = None
something: float(c_default=…) = None
something: double(c_default=…) = None
…
…

Which is, I think, one of the clearest way to express "It's an optional 
parameter, on the Python side the default value is None, but c-side the default 
value is of the right type an is …".

In other words, I'm proposing to optionally extend the "c_default" usage from 
"not given" to "not given or given None".

I failed to implement if for any types, mainly because AC is delegating to 
getargs for Py_ssize_t, so I though starting with my specific need (Py_ssize_t 
for issue28754) was a good start and POC.

Another solution may be to change the Py_ssize_t_converter to drop the 
format_unit, allowing us to implement the converter in clinic instead of 
getargs.c. It's opening a long term door of completly dropping non-"O" format 
units. I mean, if we drop every non-"O" format units in clinic we'll be able to 
use a faster implementation of _PyArg_ParseStack, one not parsing a 
mini-arg-definition-language at runtime (the "OO|nO&:").

I'm willing to implement something clean for this but please be more precise in 
your feedback.

[issue28949] Unable to launch Python interpreter

[Jason R. Coombs]

Jason R. Coombs added the comment:

I am using the python.org rc1 installer, confirmed to match the public md5 sum:

$ md5 ~/Downloads/python-3.6.0rc1-macosx10.6.pkg 
MD5 (/Users/jaraco/Downloads/python-3.6.0rc1-macosx10.6.pkg) = 
404c390ae27f067aaab34f168cf913eb

I downloaded ClamXav and had it scan my entire system. It found nothing of 
interest, only two Windows exploits, one in a driver from Asus and another in 
an attachment to an e-mail that was already filed as junk. It also found two 
"Eicar-Test-Signature" hits in old IRC logs.

So if my Mac has a virus, it's new enough that it's not being detected by 
ClamXav.

I'm going to continue to investigate and see if I can detect what event 
triggers the removal of that file.

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

Agreed with Larry. "Special cases aren't special enough to break the rules." 
General converter shouldn't be changed for just one use case. Write your own 
special converter. Or just use the "O" converter and manually convert Python 
object to C value. That can be simpler and more readable.

[issue28952] csv.Sniffer().sniff(0 returns a value without the "strict" attribute

[kevin]

New submission from kevin:

In 
  
https://docs.python.org/3.5/library/csv.html#dialects-and-formatting-parameters 

the Dialect objects are described as supporting, among others, the 
Dialect.strict attribute, with a default value of False.  However, the
sniff() returns an object lacking this attribute entirely, not even with the 
value None.  At least on my inputs, which I'd include but they have personnel 
information.  I can redact it if required.

we are promised "The flags are described in Module Contents"

Xiang Zhang added the comment:

> The code looks too complex.

It is if looking at the patch alone. But the skill is used across stringlib and 
the only thing new is the bitwise operation.

str/bytes.count is not critical but not bad if it could be optimized and 
especially the effect is significant for long data.

I am not favour of rejecting it now but set priority to low.

Barry: Sure, the docs example was just a quick write-up, you can word it 
however you want!

Guido: Pretty much, except the other way around (when prune is False, i.e. 
"don't remove empty strings").

The attached patch exposes the behaviour (it's identical to last night's, but 
I'm re-uploading it as an unrelated file went in), except that the `prune` 
argument isn't keyword-only (I didn't know how to do this, and didn't bother 
searching for just a proof-of-concept).

Isn't that what you'd expect if prune=False instead?  (i.e. prune=True always
drops empty strings from the results)

Is that the sep= idea that @syeberman suggested earlier?  If so,
then you could do:

>>> x.split(tuple(string.whitespace))

Would that suffice?

[issue28937] str.split(): remove empty strings when sep is not None

[Guido van Rossum]

Guido van Rossum added the comment:

I like the proposal. I agree that filter(None, ...) is not discoverable (and 
has its own magic).

So the proposal would be: prune=False -> empty strings stay, prune=True, empty 
strings are dropped, prune=None (default) use True if sep is None, False 
otherwise. Right?

Some end cases:

- ''.split(None, prune=True) -> ['']
- 'x  x'.split(None, prune=True) -> ['x', '', 'x']

Right?

While we're here I wish there was a specific argument we could translate 
.split(None) into, e.g. x.split() == x.split((' ', '\t', '\n', '\r', '\f')) # 
or whatever set of strings

[issue28942] await expressions in f-strings

Yury Selivanov added the comment:

> I was going to say "no", but given that "yield" works, I think it is
reasonable to allow "await" as well. (And what about "yield from"?)

Agree.

I suspect the reason is that async/await aren't proper keywords in 3.5/3.6, and 
the hacks we have in tokenizer to recognize them aren't working in f-strings.

I'll assign this issue to myself to make sure it's resolved in 3.7 once we make 
async/await keywords.

[issue28935] distutils use ConfigParser in Python 3.x and fails to parse setup.cfg with percent sign

[Axel Haustant]

Axel Haustant added the comment:

No it's not. Same problem but on a different part: the two cited issues are 
about the .pypirc file not the setup.cfg.
The parsing does not occurs at the same place and the fix does not works for 
setup.cfg (I tried before submitting this issue).

In this specific case, setuptools calls distutils to parse the file so the fix 
has to be in distutils not setuptools (whereas for .pypirc, this is setuptools 
which is parsing the file)

[issue28937] str.split(): remove empty strings when sep is not None

[Barry A. Warsaw]

Barry A. Warsaw added the comment:

I really appreciate all the feedback.  Here are some thoughts.

I'm well aware of the filter(), re, and other options, and certainly those can
be made to work, but they're non-obvious.  The reason I suggested an
enhancement to str.split() is because I've seen the replace().split() being used
far too often, and what I think is happening is that people take the most
natural path to accomplish their goals: they know they just want to do a
simple string split on a token (usually one character) so they start out with
the obvious str.split(',') or whatever.  Then they notice that it doesn't work
consistent with their mental model in some corner cases.

The next common step isn't from there to filter() or re.  The former isn't a
well-known API and the latter is viewed as "too complex".  Their next mental
step is "oh, so providing a sep has different behavior that I don't want, so
I'll just replace the comma with a space and now don't have to provide sep".
And now str.split() does what they want.  Done.  Move along.

I do wish the str.split() API was consistent w.r.t. to sep=None, but it's what
we have and is a very well known API.

@rhettinger: I'm of mixed opinion on it too!  I really wanted to get this in
the tracker and see if we could come up with something better, but so far I
still like `prune` the best.

@ebarry: Thanks for the draft docs, but that's not how I think about this.
I'd be utilitarian and get right to the point, e.g.:

"""
The value of `prune` controls whether empty strings are removed from the
resulting list.  The default value (None) says to use the default behavior,
which for backward compatibility reasons is different whether sep is None or
not (see above).  Regardless of the value of sep, when prune is True empty
strings are removed and when prune is False they are not.
"""

So @mrabarnett, +1 on the suggested defaults.

Lastly, as for Guido's admonition against boolean arguments, I would make
prune a keyword-only argument, so that forces the code to be readable and
should alleviate those concerns.  The trade-off is the extra typing, but
that's actually besides the point.  The win here is that the solution is
easily discoverable and avoids the intermediate string object.

[issue28949] Unable to launch Python interpreter

[Jason R. Coombs]

New submission from Jason R. Coombs:

I recently upgraded Python 3.6.0rc1 over 3.6.0b4. Python would invoke just fine

You can just zip up all the logs you find and attach here. I know how to read

[issue5322] Python 2.6 object.__new__ argument calling autodetection faulty

[Jeroen Demeyer]

Jeroen Demeyer added the comment:

Wouldn't it be possible to fix assignment of __new__ without breaking backwards 
compatibility (and then apply the same patch for all Python versions)? I have a 
feeling that breaking the auto-detection of tp_new is a new bug introduced by 
this patch and not a fundamental feature needed to fix assignment of __new__.

[issue28946] AttributeError: module 'signal' has no attribute 'SIGALRM'

[Chi Hsuan Yen]

Chi Hsuan Yen added the comment:

Can you import _signal? And what's the output of dir(_signal)?

Another possibility is that there's another signal.py in the search path. Could 
you also paste the output of repr(signal)?

By the way, here on Arch Linux, both signal.SIGINT and signal.SIGALRM are there.

[issue28935] distutils use ConfigParser in Python 3.x and fails to parse setup.cfg with percent sign

[Axel Haustant]

Axel Haustant added the comment:

You're welcome.

I understand the backward compatibility point. But I think that the current 
state is breaking existing code as it's not documented anywhere and it's a 
side-effect of another change, not something intentionnal.
(this is why I submitted this issue because I'm developing a tool which use the 
setup.cfg file to store data and it is broken in Python 3. I saw a lot of bug 
reports on different tools with the same issue (ex: nosetest configuration)

I cannot use %% for many reason:
- it will not work with Python 2.x (problematic for 2/3 cross compatibility)
- it needs every tools to know that in Python 3, they have to change their 
parser

Right now, I'm supporting configuration into an external file for Python 3.x

Thanks for your response ! I hope that it can be integrated into future 
releases (noted the point on 3.3/3.4).

Hi,

Post installing 'Python 3.6.0rc1 windows x86-64 web based installer' on my 
Windows 7 64 bit system, i am not able to start python. Each time i start it, i 
get a pop up saying that "the program can't start because 
'api-ms-win-crt-runtime-|1-1-0.dll' is missing from your computer. Try 
reinstalling this program to fix this problem."
I have reinstalled Python but still i get the same error message while starting 
it. I am stuck here. Please help me with this. Thanks in advance.
