[issue30103] uu package uses old encoding

[Xiang Zhang]

Xiang Zhang added the comment:

Uuencode has no official standards and it all depends on the implementation. 
For other languages, I could only find PHP, java, activetcl? have official 
implementation. PHP and activetcl defaults to backticks and no options. Java 
defaults to spaces and no options.

[issue30152] Reduce the number of imports for argparse

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

I just realized that is is not so easy to avoid gettext import. gettext is used 
in the ArgumentParser constructor for localizing names of default groups and 
the default help (besides they are used only for formatting help). This adds 
importing the locale module.

[Serhiy Storchaka]

This isn't so easy. Supporting the buffer protocol can slowdown the common case

Do you have concrete use case for this feature or add it just as an extension 
of bytes and bytearray support?

[issue30146] Difference in behavior between set() and collections.abc.MutableSet() derived objects

[Raymond Hettinger]

Raymond Hettinger added the comment:

> That being said, I believe (as the OP of issue 8743) 
> that the ABC collections should comply to the API of
> the Python base collections. 

Sorry Horacio, but your beliefs don't trump Guido's intentional design 
decisions.   He was the one who decided that the collections.abc.Set should 
have a __and__ that accepts an iterable and that it should not have the named 
methods (union, intersection, difference, etc).  Once released, that decision 
is not changeable without breaking existing code that relies on any iterable 
being accepted (which is a useful behavior given the absence of an union() 
method).   Guido also decided long ago that no class other that list would 
repeat its list.__iadd__ design mistake.   You can search the python-dev 
archives to find the discussion where it was decided that this applies to the 
concrete set type (i.e. that s |= 'abc' would raise a TypeError).  I happen to 
agree with that decision.  Though it seems to offend your sense of consistency, 
it does have the advantage of precluding what would likely be a common source 
of errors.

I'm marking this as closed.  The time to litigate API design decisions is prior 
to their being released.  This particular ship sailed a decade ago and has 
mostly worked out fine for all of our users.

[issue29621] telnetlib.Telnet.write gives confusing error message when a string is passed in

[R. David Murray]

R. David Murray added the comment:

We generally don't do this kind of type checking in the standard library.  The 
message may not be clear, but it is accurate and decipherable, especially given 
the fact that the write parameter name is 'buffer'.  I don't think anything 
should be done here.  If you want type checking use the types module :)

Thanks for the PR, @corona10, but I think we should just close this issue.  
Other devs may disagree, though, so I'm not closing it myself.

On the other hand, enhancing telnetlib to also work with strings might be a 
nice project for someone.  It would require some design discussion, though, so 
I don't think anyone should hop on it without discussing it somewhere first 
(python-ideas, maybe?).

[issue30173] x86 Windows7 3.x buildbot has the issue #26624 bug

[David Bolen]

David Bolen added the comment:

Yeah, there were a few transient build errors while I was getting the buildbot 
back online.  My initial attempt to fix this ticket involved using the VS 2015 
installer which turned out very badly, so I had to fall back to an older VM 
image and start over.  But the older image had an older buildbot version which 
didn't work with the git workflow, which hit a few pending builds before I got 
it fixed.

I'm not yet sure if there may be some other fallback (e.g., the link error in 
the recent 3.x build seems familiar but I can't recall why offhand)

[issue30103] uu package uses old encoding

[Martin Panter]

Martin Panter added the comment:

FWIW I am using NXP LPC microcontrollers at the moment, whose bootloader uses 
the grave/backtick instead of spaces. (NXP application note AN11229.)  Although 
in practice it does seem to accept Python's spaces instead of graves.

I wouldn't put too much weight to Wikipedia, especially where it says graves 
are not used for encoded data (vs length and padding). Earlier versions of 
Wikipedia did mention graves in regular data.

I understand the reason for avoiding spaces is to due to spaces being stripped 
(e.g. by email, copy and paste, etc). You have to avoid spaces in data, not 
just padding, because a data space may still appear at the end of a line.

It appears as if my Win8 and Win10 buildbots also have the older dll, so I'm

I'll plan on addressing them in the near future as well.

IDLE's debugger needs multiple patches.  It is based on bdb.  So I want to be

will help in reviewing the patch.

[issue30192] hashlib module breaks with 64-bit kernel and 32-bit user space

[Neil Schemenauer]

New submission from Neil Schemenauer:

The test in setup.py to check for SSE2 support is incorrect.  Checking that 
arch == x86_64 is not sufficient.  If the kernel is 64-bit but Python is 
compiled with a 32-bit compiler, the _blake2 module will fail to build.

The attached patch fixes this issue. I did a quick search of the x86_64 string, 
I don't see this mistake being made elsewhere but I imagine it could be done 
elsewhere.  Obviously a machine with a 64-bit kernel and 32-bit userspace is a 
rare as hen's teeth these days.  Still, I think it is worth fixing this bug.

[issue30186] Python interpreter calling "PathCchCombineEx" on startup, Windows 8 and above only

[Steve Dower]

Steve Dower added the comment:

The approach I used is the correct way to use the function if it's available. 
If Wine is not supporting this function, it should return NULL from 
GetProcAddress, not a stub. If the function exists, any error it returns is 
fatal.

We need the better function for Win10 in order to support paths longer than 260 
characters. PathcombineW fails on long paths.

[issue30186] Python interpreter calling "PathCchCombineEx" on startup, Windows 8 and above only

[R. David Murray]

R. David Murray added the comment:

Indeed, it sounds like wine is claiming to be Windows 7 but then implementing 
(as not implemented) later-than-windows-7 apis.  That definitely sounds like a 
bug in wine.

why is it unknown? 
Also, I have to type everything in shell, since it does not show me the

[issue30186] Python interpreter calling "PathCchCombineEx" on startup, Windows 8 and above only

[Eryk Sun]

Eryk Sun added the comment:

I didn't mean that there's support to fall back on PathCombineW if 
PathCchCombineEx returns E_NOTIMPL. I was just guessing at what the stub in 
Wine might be doing. I took a look at the source. It seems the Wine stub 
function for unimplemented functions is __wine_spec_unimplemented_stub in 
dlls/winecrt0/stub.c, which calls RaiseException. 

I think this issue should be closed as 3rd party since I don't see anything 
wrong with Steve's code, but I'll leave it open for Steve to make that decision.

[issue30190] unittest's assertAlmostEqual should show the difference

[Giampaolo Rodola']

New submission from Giampaolo Rodola':

When comparing 2 numbers as "self.assertAlmostEqual(a, b, delta=1000)" the 
error message looks like this:

AssertionError: 27332885 != 27391120 within 1000 delta

Especially when a and b are big numbers or differ a lot, it would be useful to 
see the absolute difference between the 2 numbers as in:

AssertionError: 27332885 != 27391120 within 1000 delta (58235 difference)

[issue30146] Difference in behavior between set() and collections.abc.MutableSet() derived objects

[R. David Murray]

R. David Murray added the comment:

I suppose someone could propose a set of tests that an implementation of an ABC 
type should pass, to complement the stdlib type tests.  There would probably be 
a lot of bikeshedding involved in such tests though, so I don't hold out great 
hope anything would ever get accepted for merge :)

[issue30146] Difference in behavior between set() and collections.abc.MutableSet() derived objects

[R. David Murray]

R. David Murray added the comment:

For backward compatibility reasons, history will win.  

I'm not sure if documenting the additional restrictions of the concrete stdlib 
types in the ABC docs makes sense, either, since the ABCs are intentionally the 
minimal requirements for a concrete type to conform to the ABC.  The concrete 
ABC methods are really examples, even though they are also widely useful (and 
widely used).

[issue30186] Python interpreter calling "PathCchCombineEx" on startup, Windows 8 and above only

[Eryk Sun]

Eryk Sun added the comment:

PathCchCombineEx isn't an import dependency. It's used dynamically via 
LoadLibraryW and GetProcAddress, with a fallback to PathCombineW. Does Wine 
maybe have a stub for this function that returns E_NOTIMPL (not implemented)?

[issue30189] SSL match_hostname does not accept IP Address

[Christian Heimes]

Christian Heimes added the comment:

In general we don't backport features. 
https://www.python.org/dev/peps/pep-0466/ allows backports of network security 
enhancements. However IP address validation is not a security enhancement. You 
can either update to a new version of Python or role your own verification code.

[issue30146] Difference in behavior between set() and collections.abc.MutableSet() derived objects

[Horacio Hoyos]

Horacio Hoyos added the comment:

Although I agree that some design decisions forge a language and sometimes 
these historical developments win over sounder or more "logical" arguments.

That being said, I believe (as the OP of issue 8743) that the ABC collections 
should comply to the API of the Python base collections. In that sense, I would 
expect any custom collection implemented by extending the ABC collections to be 
used in place of an exiting base one, without any "hiccups". Thus, the custom 
collection should pass all the tests in the Lib/tests.

Of course, for the moment, this would just require extra work on my part in 
order to implement all the magic methods and such.

If history is to win again, then at least the documentation of the ABC  
collections should clearly state the subtle, but IMHO important, differences 
between the two.

[issue30103] uu package uses old encoding

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

What about other popular languages? Java, PHP, Ruby, Tcl, C#, JavaScript, 
Swift, Go, Rust? Do any languages provide a way for configuring zero character 
and what are the names of the options? Are there languages that use "`" instead 
of a space only for padding, but not for representing an ordinal zero?

[issue30103] uu package uses old encoding

[Xiang Zhang]

Xiang Zhang added the comment:

There seems no standard. I also read the wikipedia but for perl and uuencode on 
my Linux, they now all use backticks to represent zero instead of spaces.

[~]$ perl -e 'print pack("u","Ca\x00t")'
$0V$`=```
[~]$ cat /tmp/test
Ca[~]$ uuencode /tmp/test -
begin 664 -
"0V$`
`
end

while Python now:

>>> import uu
>>> uu.encode('/tmp/test', '-')
begin 664 test
"0V$ 
 
end

Except the link Kyle gives, the manpage of FreeBSD describes the new algorithm: 
http://www.unix.com/man-page/freebsd/5/uuencode/

I don't propose to change current behaviour to break backwards compatibility. 
But I think it's reasonable to provide a way to allow users to use backticks.

[issue30103] uu package uses old encoding

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

Is there any standard?

>From Wikipedia [1]:

"""
Note that 96 ("`" grave accent) is a character that is seen in uuencoded files 
but is typically only used to signify a 0-length line, usually at the end of a 
file. It will never naturally occur in the actual converted data since it is 
outside the range of 32 to 95. The sole exception to this is that some 
uuencoding programs use the grave accent to signify padding bytes instead of a 
space. However, the character used for the padding byte is not standardized, so 
either is a possibility.
"""

This obviously makes impossible using "`" as zero instead of space.

[issue27593] Deprecate sys._mercurial and create sys._git

[STINNER Victor]

STINNER Victor added the comment:

Ned Deily: "I'll be doing backports to 2.7 for this and some other things 
shortly."

It seems like Ned was busy or forgot 2.7, so I wrote a change: 
https://github.com/python/cpython/pull/1327

My change doesn't touch platform.py. platform._sys_version() uses 
sys.subversion but not sys._hg. If someone wants to enhance the platform module 
of Python 2.7, I suggest to open a new issue. There is a non-zero risk of 
breaking the backward compatibility, so I skipped my turn for that one :-)

[issue30152] Reduce the number of imports for argparse

[Antoine Pitrou]

Antoine Pitrou added the comment:

I'd like to vote for a lazy import system that would benefit everyone (many 
third-party packages are also affected by startup time issues), but I've seen 
enough handwaving about it along the years that I'm not really hoping any soon. 
 My own limited attempts at writing one have failed miserably.

In other words, I think Serhiy's proposal is a good concrete improvement over 
the statu quo.

[issue30187] Regex becomes invalid in python 3.6

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

This is ambiguous syntax. Unknown escapes consisting of '\' and ASCII letter 
were deprecated in 3.5 (run the interpreter with the option -Wa to see all 
warnings) and are errors since 3.6. Note that the string literal '[^\B]' itself 
produces a DeprecationWarning in 3.6.

[issue30175] Random test_imaplib.test_logincapa_with_client_certfile failure on x86 Gentoo Installed with X 3.x

[STINNER Victor]

STINNER Victor added the comment:

I proposed a quick fix to repair our development process (CI) and buildbots, 
skip the two failing files:
https://github.com/python/cpython/pull/1320/

I would give our more time to decide what to do:

* contact cyrus.andrew.cmu.edu sysadmin to ask him/her to accept our client 
cert or revert their IMAP config :-)
* setup a new IMAP server accepts this client cert on pythontest.net
* mock a IMAP server in test_imaplib: mock everything (no network), or "real" 
TCP server doing the TLS handshake? Mock everything doens't make sense for a 
unit test designed to use "remote" resources?

[issue30175] Random test_imaplib.test_logincapa_with_client_certfile failure on x86 Gentoo Installed with X 3.x

[STINNER Victor]

STINNER Victor added the comment:

> accepts random TLS certs.

I tried "imap.gmail.com" server: first, it fails with:

imaplib.IMAP4.error: b'[AUTHENTICATIONFAILED] Invalid credentials (Failure)'

And then:

imaplib.IMAP4.error: b'[ALERT] Web login required: 
https://support.google.com/mail/answer/78754 (Failure)'

Well, I don't see why an IMAP server would accept our client cert?

Lib/test/keycert3.pem was added by the commit 
58ddc9d743d09ee93d5cf46a4de62eab30dad79d (made by Antoine Pitrou): the 
certificated was *generated* randomly by Lib/test/make_ssl_certs.py (also added 
by the same commit).

RemoteIMAP_SSLTest was added by commit b1436f185dac249f0f6dc342b2a543ae2d1db63d 
(Antoine Pitrou) in 2010 with the server: cyrus.andrew.cmu.edu.

So since 2010 until a few days ago, cyrus.andrew.cmu.edu accepted random client 
certificate, but now the server started to fail... as expected?

[Antoine Pitrou]

Antoine Pitrou added the comment:

test_logincapa_with_client_certfile and test_logincapa_with_client_ssl_context 
both fail accordingly.

test_ssl_context_certfile_exclusive and test_ssl_context_keyfile_exclusive 
raise another error (ValueError) and succeed expectedly.

Wait, the test tries to connect to a public IMAP server using a x509 client 
certificate? Wow, I'm surprised that it works sometimes :-)

In RemoteIMAP_SSLTest, I see 3 unit tests which use create_ssl_context(), the 
method which loads the client certificate, but I only see 2 failures, not 3. 
Should I understand that sometimes the TLS connection succeeded, but sometimes 
it fails, on the same server? Strange :-)

[issue30052] URL Quoting page links to function Bytes instead of defintion

[Nick Coghlan]

Nick Coghlan added the comment:

Indeed, checking the dev build at 
https://docs.python.org/dev/library/urllib.parse.html#url-quoting shows it 
still linking to the old location.

Perhaps the `autobuild-dev-html` target in the Makefile should be adding `-E` 
and `-a` so it always regenerates everything, rather than re-using the 
potentially stale cached info from the previous day?

[issue30183] [HPUX] compilation error in pytime.c with cc compiler

[STINNER Victor]

STINNER Victor added the comment:

I'm quite sure that once I wrote a patch using gethrtime() for Solaris, but 
then I saw that it's the same clock than clock_gettime(CLOCK_MONOTONIC), so I 
removed gethrtime() to simplify the code.

See also my PEP 418, which mentions gethrtime() by the way:
https://www.python.org/dev/peps/pep-0418/#solaris-gethrtime

Thanks, I'll work on getting a patch that leverages gethrtime() tested and
