[issue31484] Cache single-character strings outside of the Latin1 range

2017-09-16 Thread Ezio Melotti 

Ezio Melotti added the comment:

> The cache of size 2 x 256 slots can increase memory consumption by 50 KiB in 
> worst case, 2 x 1024 -- by 200 KiB.

How much is this compared to the total usage?

> But I don't know how common `for c in s` or `s[i]` is used for Japanese text.

I think the same applies to other languages/scripts too, so this optimization 
might be moot unless the cache also improves performances of other more common 
operations (e.g. encoding/decoding).

It would be interesting to see how this affects real-world application: if 
there are no regressions and the memory overhead is not too much I think we can 
accept the patch.

[issue31495] Wrong offset with IndentationError ("expected an indented block")

2017-09-16 Thread Martin Panter 

Martin Panter added the comment:

Some relevant info I wrote in Issue 25677:

‘The caret points to the character _before_ offset. . . . In some cases (e.g. 
the line “1 +”), the offset is the string index _after_ the error. But in the 
case of “1;1 + 1 = 2”, offset is the index where the error (statement) begins.’

In this case it looks like the offset is of the end of the first word on the 
line that has the wrong indentation. The caret is positioned one position back, 
to point at the last character of that word.

[issue10496] Python startup should not require passwd entry

2017-09-16 Thread R. David Murray 

R. David Murray added the comment:

Dmitriy: you will note from the discussion on this issue that your "simple 
patch" was not considered sufficient.  There were additional concerns voiced 
about haypo's patch, which is why I guess it didn't get applied.  However, can 
you review that and confirm that it solves your problem?  Maybe that will 
encourage a reconsideration of this issue.

python t-expected-indent.py reports:

```
  File "t-expected-indent.py", line 2

IndentationError: expected an indented block

[issue31493] IDLE cond context: fix code update and font update timers

2017-09-16 Thread Terry J. Reedy 

New submission from Terry J. Reedy:

1. Currently, each instance of codecontext.CodeContext creates 2 root.after 
loops.  There should be at most two loops for the class, and preferably fewer 
by using the new reload().

2. The loops are never explicitly shut down.  Since conversion to a feature,  
the following appears after running test_idle.

.invalid command name "109891384timer_event"
while executing
"109891384timer_event"
("after" script)
invalid command name "109891512font_timer_event"
while executing
"109891512font_timer_event"
("after" script)

This is because of
  File "F:\dev\3x\lib\idlelib\idle_test\test_outwin.py", line 20, in setUpClass
w = cls.window = outwin.OutputWindow(None, None, None, root)
  File "F:\dev\3x\lib\idlelib\outwin.py", line 78, in __init__
EditorWindow.__init__(self, *args)
  File "F:\dev\3x\lib\idlelib\editor.py", line 319, in __init__
  text.bind("<>",  # added to traceback
self.CodeContext(self).toggle_code_context_event)

The statement, which creates an instance, was added as part of the conversion.  
However, the outwin tests were merged a week before the conversion, so this 
message might have started the.  In any case, 
editor.EditorWindow.load_extension does the same thing in doing the binding.  
It is not clear why there is no message from other editor-creating tests. 

I want to fix at least this before next Monday's cutoff for new releases.  I 
will first try is after_cancel in a __del__ method.

[issue31492] assertion failures in case a module has a bad __name__ attribute

2017-09-16 Thread Oren Milman 

New submission from Oren Milman:

The following code causes an assertion failure:
import os
os.__name__ = None
os.does_not_exist

this is because module_getattro() (in Objects/moduleobject.c) assumes that
__name__ is a string, and passes it to PyErr_Format(), which asserts it is a
string.


if we fixed that one (so that the code above would raise an AttributeError),
the following code would still cause an assertion failure:

import os
os.__name__ = None
from os import does_not_exist


this is because import_from() (in Python/ceval.c) also assumes that __name__
is a string, and passes it to PyUnicode_FromFormat(), which asserts it is a
string.


BTW, while we are in module_getattro(): isn't the second call to PyErr_Clear()
redundant? (Ethan, IIUC, you worked on this as part of #8297 some years ago..)

[issue27391] server_hostname should only be required when checking host names

2017-09-16 Thread Christian Heimes 

Christian Heimes added the comment:

So it's not a problem with the SSL module but rather in asyncio. From the 
initial report it was not clear to me that it only affects asyncio.

I'm not sure this issue should be fixed at all. As I explained earlier, a 
hostname is required for both hostname verification and SNI TLS extension. We 
may allow to omit the parameter with verify_mode=CERT_NONE and 
check_hostname=False only. In all other cases the server may return a wrong 
cert or refuse to establish a connection.

You are right, the path is wrong on Unix-like platforms. It's

[issue31491] Add is_closing() to asyncio.StreamWriter.

2017-09-16 Thread Aymeric Augustin 

New submission from Aymeric Augustin:

asyncio.StreamWriter wraps a transport. The first three document methods of 
asyncio.BaseTransport are close(), is_closing() and get_extra_info().

It is somewhat surprising that StreamWriter provides close() and 
get_extra_info() but not is_closing(). I'm proposing that StreamWriter 
implement is_closing() as well.

It's as simple as:

def is_closing(self):
return self._transport.is_closing()

Perhaps it was simply missed in https://github.com/python/asyncio/pull/291.

It's trivial to work around this omission with 
stream_writer.transport.is_closing().

I'm only suggesting to add it for consistency.

[issue31490] assertion failure in ctypes in case an _anonymous_ attr appears outside _fields_

2017-09-16 Thread Oren Milman 

New submission from Oren Milman:

The following code causes an assertion failure:
import ctypes
class BadStruct(ctypes.Structure):
_fields_ = []
_anonymous_ = ['foo']
foo = None


this is because MakeAnonFields() (in Modules/_ctypes/stgdict.c) goes over the
names specified in _anonymous_, and looks each name up in the class by calling
PyObject_GetAttr().
in case an attribute of such a name is found (i.e. PyObject_GetAttr() 
succeeded),
MakeAnonFields() assumes that the attribute was created by MakeFields(), so it
asserts the type of the attribute is PyCField_Type.

however, PyObject_GetAttr() would succeed also in case it is a normal attribute
specified by the user, but isn't specified in _fields_, as in the code above.
in such a case, the type of the attribute is not PyCField_Type, and so the
assertion fails.

Interesting optimization.  But I don't know how common `for c in s`
or `s[i]` is used for Japanese text.

[issue31484] Cache single-character strings outside of the Latin1 range

2017-09-16 Thread Serhiy Storchaka 

Serhiy Storchaka added the comment:

Initially I used 2 x 128 slots. It is enough for single block alphabetic 
languages. But it was caused significant slow down for Chinese. Increasing the 
size to 2 x 256 compensates the overhead for Chinese and restores the 
performance. If it is appropriate that the optimization affects only languages 
with small alphabets and keeps the performance for Chinese, Japan and Korean 
roughly unchanged (plus-minus few percents), this size is enough. I we want to 
optimize also processing texts with Chinese characters, it can be increased to 
2 x 512 or 2 x 1024. Further increasing have smaller effect.

The cache of size 2 x 256 slots can increase memory consumption by 50 KiB in 
worst case, 2 x 1024 -- by 200 KiB.

[issue31182] Suggested Enhancements to zipfile & tarfile command line interfaces

2017-09-16 Thread Serhiy Storchaka 

Serhiy Storchaka added the comment:

The command-line interface of zipfile and tarfile modules was deliberately kept 
simple. If you need more complex functionality, just write a script. Python is 
a programming language!

> 1. Wildcard filename matching for archiving

This is a work for a shell. Interpreting wildcards by a program breaks 
compatibility and makes impossible to handle files containing special 
characters. For example it breaks:

python3 -m zipfile -c myzip.zip "The Book [vol. 5].txt".

No way.

> 2. Recursive archiving (with excludes)

Archiving already is recursive. It may be worth to add an option for adding 
directories not recursively.

> 3. Append to archive option

May be. I don't know what to do with compressed tar archives.

> 4.1 For zipfile: zip64, bizp2 & lzma (if available)

Would be nice. And this option could force compression for tarfile.

As new features they can be added only in 3.7.

[issue13487] inspect.getmodule fails when module imports change sys.modules

2017-09-16 Thread Serhiy Storchaka 

Serhiy Storchaka added the comment:

dict.copy() is not thread-safe still (but it can be made thread-safe).

list(dict) is thread-safe. It copies a list of keys only.
