[issue23556] Scope for raise without argument is different in Python 2 and 3

[John Mark Vandenberg]

John Mark Vandenberg added the comment:

In pyflakes we've looked at some of the strange scenarios where a raise without 
argument is 'legal'.  A patch to report errors for some of these was rejected 
because they are legal. See https://github.com/pyflakes/pyflakes/pull/57  The 
worst example of 'legal' is an exception in one module can be re-raised by 
another module.

[issue25911] Regression: os.walk now using os.scandir() breaks bytes filenames on windows

[Eryk Sun]

Eryk Sun added the comment:

Considering there's no plan to implement bytes paths for scandir on Windows, 
then the following line in the os docs needs to be modified: "All functions 
accepting path or file names accept both bytes and string objects, and result 
in an object of the same type, if a path or file name is returned." It should 
be changed to acknowledge that some functions on Windows do not support bytes 
paths, and that existing support is deprecated and may be removed in a future 
release.

Also, the docs for listdir should warn that using bytes returns invalid results 
on Windows when filenames contain characters that aren't mapped in the system 
locale codepage.

[issue25932] Windows installer ships an outdated and insecure curl.exe

[Ismail Donmez]

New submission from Ismail Donmez:

Installed Python 3.5.1 windows x64 version and ended up having

C:\Users\ismail\AppData\Local\Programs\Python\Python35\curl.exe

which is outdated:

C:\Users\ismail>C:\Users\ismail\AppData\Local\Programs\Python\Python35\curl.exe 
-V
curl 7.37.0 (Windows) libcurl/7.37.0 OpenSSL/1.0.2d zlib/1.2.8
Protocols: dict file ftp ftps gopher http https imap imaps pop3 pop3s rtsp smtp 
smtps telnet tftp
Features: NTLM SSL libz

That is released in May 2014!

Also its insecure:

C:\Users\ismail>C:\Users\ismail\AppData\Local\Programs\Python\Python35\curl.exe 
- "https://www.g
oogle.com"
* Rebuilt URL to: https://www.google.com/
* timeout on name lookup is not supported
* Hostname was NOT found in DNS cache
*   Trying 173.194.32.177...
* Connected to www.google.com (173.194.32.177) port 443 (#0)
* libcurl is now using a weak random seed!
[...]

I would be happy if you don't ship curl at all, or at least use a secure, 
up-to-date version from https://bintray.com/vszakats/generic/curl/view

[issue25864] collections.abc.Mapping should include a __reversed__ that raises TypeError

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

I agree that by default calling reversed() on mapping should raise a TypeError. 
But for now issubclass(collections.abc.Mapping, typing.Reversible) returns 
False. If add default __reversed__ implementation this test will return True. 
We have to find other way to make Mapping true non-reversible in all meanings.

Perhaps there is a bug in typing.Reversible. It doesn't accept all types 
supported by reversed().

>>> class Counter(int):
...   def __getitem__(s, i): return i
...   def __len__(s): return s
... 
>>> list(reversed(Counter(10)))
[9, 8, 7, 6, 5, 4, 3, 2, 1, 0]
>>> issubclass(Counter, typing.Reversible)
False

And accepts types that don't work with reversed().

>>> class L(list):
...__reversed__ = None
... 
>>> reversed(L())
Traceback (most recent call last):
  File "", line 1, in 
TypeError: 'NoneType' object is not callable
>>> issubclass(L, typing.Reversible)
True

[issue25420] "import random" blocks on entropy collection on Linux with low entropy

[Thomas Petazzoni]

Thomas Petazzoni added the comment:

I can confirm that I'm affected by the same issue. Booting a simple Linux 
system on a Qemu ARM platform, the python startup hangs during 25 seconds due 
to the call to getrandom(). I am not doing anything with Python, just starting 
the Python interpreter:

# strace -t -o strace.log python
random: nonblocking pool is initialized
Python 3.5.0 (default, Dec 23 2015, 15:11:18) 
[GCC 5.1.1 20150608] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>>  
# grep -A 2 getrandom strace.log 
14:43:50 
getrandom("\245\362a=\305\32Z\263\364\352j\223\0017\302q\361M\336+\2722>[", 24, 
0) = 24
14:44:35 ioctl(0, TCGETS, {B38400 opost isig icanon echo ...}) = 0
14:44:35 mmap2(NULL, 262144, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, 
-1, 0) = 0x76baf000

As you can see, 25 seconds blocked due to the getrandom() system call. Makes 
the Python interpreter not really usable anymore. I would understand if Python 
would do when I need to generate cryptographically secure random numbers. But 
at this point, I am just starting the interpreter, nothing else.

This is a regression from Python 3.4.3.

[issue25157] Installing Python 3.5.0 32bit on Windows 8.1 64bit system gives Error 0x80240017

[Joakim Karlsson]

Joakim Karlsson added the comment:

I got this working on a Windows 8.1 box with the following mess. Hopefully 
someone more capable than me can piece together a viable fix from this.

I downloaded and executed the Visual C++ Redistributable for VS 2015 here: 
https://www.microsoft.com/en-us/download/details.aspx?id=48145

I then watched that installation fail with the same error as in the python 
installer.

>From the steps described here: http://stackoverflow.com/a/31536998

1. Copy the file "C:\ProgramData\Package 
Cache\FC6260C33678BB17FB8B88536C476B4015B7C5E9\packages\Patch\x64\Windows8.1-KB2999226-x64.msu"
 to c:\temp\

(Note: the guid in the path above is not the same as in the stack overflow 
answer. It seems it may vary)

2. From an elevated (important!) command prompt:

>cd c:\temp
>mkdir extracted
>wusa.exe Windows8.1-KB2999226-x64.msu /extract:extracted

(Make sure files are extracted to the new dir)

>dism.exe /Online /Add-Package 
>/PackagePath:extracted\Windows8.1-KB2999226-x64.cab

3. Run vc_redist.x64.exe again, and choose repair

4. Now, I could finally install Python (3.5.1)

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

Here is a patch that fixes an infinite loop reported in msg254071. May be this 
is not the best solution. It makes the behavior of Python and C implementation 
differ (the former just iterates a linked list, the latter raises an error). 
But to reproduce Python implementation behavior we need to add refcounters to 
linked list nodes.

[issue25920] PyOS_AfterFork should reset socketmodule's lock

[Ronald Oussoren]

Ronald Oussoren added the comment:

#25924 is related to this, I filed this after reading the blog post. The lock 
might not be necessary on OSX, and possibly on the other systems as well.


Yury: resetting the lock in the child should be safe because after the fork the 
child only has a single thread that is returning from fork(2). The thread that 
acquired the lock does not exist in the child process.

[issue25933] Unhandled exception (TypeError) with ftplib in function retrbinary/retrlines causes inoperable behavior without crashing

[Sam Adams]

New submission from Sam Adams:

Hello,

I believe that I found a bug in ftplib.py in version 3.3.6.

Whenever a user opens a file for writing in nonbinary mode and then proceeds to 
call the retrbinary function, or opens the file in binary mode and proceeds to 
call the retrlines fuction, then attempts to write to the file using the 
callback function, an unhandled TypeError exception is raised that does not 
cause the program to crash, but rather cause the last message from the server 
to not be "read" by the readline() function, thus causing cascading errors 
until the function readline() is called on its own or the connection with the 
server is reset.

Code to replicate:
from ftplib import FTP
ftp = FTP('your.server.here')
ftp.login()
fileTest = open('filename','w') < not binary
ftp.retrbinary('retr randomfilehere',fileTest.write)

Unhandled exception raised: 

File "/usr/local/lib/python3.3/ftplib.py", line 434, in retrbinary
callback(data)
TypeError: must be str, not bytes

Likewise, if 

ftp.retrlines('retr randomfilehere', fileTest.write) 

is called when fileTest is opened for writing with binary option the following 
error is raised:

File "/usr/local/lib/python3.3/ftplib.py", line 464, in retrlines
callback(line)
TypeError: 'str' does not support the buffer interface

Calling ftp.getline() clears the error and resumes normal operation


Possible Solution:

add exception handling in lines 434/464 for TypeError

[issue25933] Unhandled exception (TypeError) with ftplib in function retrbinary/retrlines causes inoperable behavior without crashing

[Sam Adams]

Sam Adams added the comment:

Silent: The issue that i see is how the error is handled. I can trap the 
TypeError easily, however, if I keep the socket open, the behavior of ftplib 
will not be as intended. For example:

fileTest = open('filename1', 'wb')

ftp.retrlines('RETR README.html', fileTest.write)

This will give a TypeError, as intended

However, what happens next is, I believe, not intended --

If i send a command after this trapped error, say, ftp.sendcmd('NOOP')

The result will not be 
200 NOOP command successful

but, instead,

226 Transfer Complete

As the previous status was not read from the file created by the socket, so if 
i want to try and do anything for the user after, the message received, and 
subsequently parsed by the getresp function, will not be the message that is 
expected.

For a noop command this is ok, but for a transfer command, it will set the mode 
to either A or I and return a 200 status when a different status was expected. 
This will raise an error. 

The only way to fix this is to either run the internal function getline() or 
reset the connection, thus clearing all messages from the file.

I have attached a file that has a fix, Im not sure if this is helpful or not.

I modified the retrbinary function on lines:
440,449-450,454-455

I also modified the retrlines function on lines:
470,490-491,496-497

[issue25936] Improve FastChildWatcher with WNOWAIT?

[WGH]

New submission from WGH:

The problem with FastChildWatcher lies in the fact that it can accidentally 
reap processes that it doesn't watch.

However, os module includes waitid function (since Python 3.3), and it has 
WNOWAIT flags, which means "return status, let process remain waitable (=don't 
reap)".

What do you think, can this feature fix the problem with FastChildWatcher?

if __name__ == '__main__':
s = '中文'
print s, chardet.detect(s) 

I execute it and everything is ok. However it raise "SyntaxError" (as I 
expected) after I change "encoding:utf-8" to "encoding:utf8".

  File "gbk-utf8.py", line 2
SyntaxError: 'utf8' codec can't decode byte 0xd6 in position 0: invalid 
continuation byte

Is this ok? Or where I wrong?

[issue25928] Improve performance of statistics._decimal_to_ratio and fractions.from_decimal

[John Walker]

Stefan, _int is a slot in Lib/_pydecimal.py. It should be defined on python 3.5 
and tip, unsure about other versions.

Python 3.5.1 (default, Dec  7 2015, 12:58:09) 
[GCC 5.2.0] on linux

That should only happen if the C version did not build for some reason:

Oh, OK. I see whats happening. My distro deletes the shipped version and 
compiles --with-system-libmpdec. We're on the same page now, thanks.

[issue12484] The Py_InitModule functions no longer exist, but remain in the docs

[Berker Peksag]

Berker Peksag added the comment:

The patch looks good to me.

_PyImport_FixupExtension does not exist in Python 3, but it's still documented 
in Doc/c-api/import.rst. We need to remove it, too.

(Or we could document _PyImport_FixupExtensionObject since there are already 
documented internal functions in that file.)

[issue25928] Add Decimal.as_integer_ratio()

[Stefan Krah]

Stefan Krah added the comment:

Let's re-target this issue:

Implementing as_integer_ratio() sounds reasonable, but let's hope
people won't try to convert Decimal('1E+99').


Mark, was there perhaps a reason not to add the method?

[issue25934] ICC compiler: ICC treats denormal floating point numbers as 0.0

[Stefan Krah]

New submission from Stefan Krah:

Zachary in #24999:

"If that's the case, would anyone (in particular, Steve, Tim or Tim) mind if we 
just made the default (for MSVC as well as ICC) /fp:strict?  It would be much 
easier to just change the global default than to try to either make it settable 
or to change it just when ICC is used."

That would also be good as it will decrease the API differences between 
floats and Decimals and make it easier to duck-type one for the other.

[issue25938] if sentence doesn't work with input()

In Python 2, input() is basically equivalent to eval(raw_input()). In Python 3, 
input() is the same as raw_input() in Python 2. This explains the difference.

[issue25938] if sentence doesn't work with input()

[Kozo Oeda]

New submission from Kozo Oeda:

if sentence doesn't work well with input() in Python 3(I confirmed 3.4.3 and 
3.5.1 on OS X 10.10.5). I also confirmed Python 2.7.11 works well. I think the 
code which I wrote in the lower section explains what happened enough. 

I couldn't get the proper component so I selected Interpreter Core temporally.
Thanks 

#Code Start=
#Python 3.4.3 and 3.5.1 on OS X 10.10.5

def test(a):
if a == 0:
print("0")
else:
print("not 0")

a = input()
print(a)
test(a)

# Input 
# 0 
#
# Output
# 0
# 0
# not 0

# Input
# 1
#
# Output
# 1
# 1
# not 0
