New submission from Serhiy Storchaka:

Some documentation files contain a number of I/my/me. Looks like they grew from 
personal modules and personal articles. Perhaps the official documentation 
needs more depersonalized style. Here is full list of such files:

Doc/c-api/exceptions.rst
Doc/c-api/long.rst
Doc/distutils/builtdist.rst
Doc/extending/extending.rst
Doc/extending/windows.rst
Doc/howto/argparse.rst
Doc/howto/curses.rst
Doc/howto/functional.rst
Doc/howto/regex.rst
Doc/howto/sockets.rst
Doc/howto/urllib2.rst
Doc/install/index.rst

Doc/library/ossaudiodev.rst
Doc/library/tk.rst
Doc/library/unittest.mock-examples.rst
Doc/library/unittest.mock.rst
Doc/reference/introduction.rst
Doc/tutorial/classes.rst

The list doesn't include FAQs where it may be appropriate and whatsnew files.

Andrew Kuchling recently has fixed Doc/howto/unicode.rst for this issue (as 
part of issue4153).

The tarfile module defines a bunch of stat constants:

http://hg.python.org/cpython/file/4465f273a8a4/Lib/tarfile.py#l142

These constants aren't documented but they look like public API constants. I

[issue18282] Ugly behavior of binary and unicode handling on reading unknown encoded files

2013-06-22 Thread Sworddragon


New submission from Sworddragon:

Currently Python 3 has some problems of handling files with an unknown 
encoding. In this example we have a file encoded as ISO-8859-1 with the content 
"ä" which should be tried to be read. Lets see what Python 3 can currently do 
here:

1. We can simply open the file and try to read the content. The encoding will 
be set in my case automatically to UTF-8. But the read() operation will throw 
an exception: UnicodeDecodeError: 'utf-8' codec can't decode byte 0xe4 in 
position 0: unexpected end of data

2. Now lets look a little more into the arguments of open(): We will find an 
errors argument which could maybe be useful:
2.1. "strict" is the default behavior which was already tested.
2.2. "ignore" will not throw any exception but delete any character which can't 
be read. This would be problematic in many cases.
2.3. "replace" will replace any character which can't be read which will be 
problematic in many cases too.
2.4. "surrogateescape" can throw exceptions too: UnicodeEncodeError: 'utf-8' 
codec can't encode character '\udce4' in position 0: surrogates not allowed
2.5. "xmlcharrefreplace" and "backslashreplace" are not used for reading.

3. Since trying to decode the file will make many problems we can try to read 
the file as binary content. This will work in all cases but causing another 
problem: Any unicode string that must be concatenated with the content of the 
file must be converted to a binary string too (like b'some_unicode_content' or 
some_unicode_variable.encode()). The same happens for unicode strings that must 
be concatenated somewhere else with the newly converted unicode_to_binary 
variable even if they doesn't touch the file content. This behavior can affect 
the maintainability in a bad way.


As you can see all current solutions of Python 3 have big disadvantages. If I'm 
overlooking something feel free to correct me. Currently I have developed my 
own solution in Python which solved the problem: A function that autodetects 
the encoding of the file. Maybe there could also be a native way to do this on 
open() or maybe there could be another way found to solve this problem.

[issue18236] int() and float() do not accept strings with trailing separators


Alexander Belopolsky added the comment:

> You stated facts: what is your proposal?

There is a bug somewhere.  We cannot simultaneously have

>>> '\N{RS}'.isspace()
True

and not accept '\N{RS}' as whitespace when parsing numbers.

I believe int(x) should be equivalent to int(x.strip()).  This is not the case 
now:

>>> '123\N{RS}'.strip()
'123'
>>> int('123\N{RS}')
Traceback (most recent call last):
  File "", line 1, in 
ValueError: invalid literal for int() with base 10: '123\x1e'

The reason I did not clearly state my proposal is because I am not sure whether 
bytes.isspace or str.isspace is correct, but I don't see any justification for 
having them defined differently in the ASCII range.

[issue18236] int() and float() do not accept strings with trailing separators

Terry J. Reedy added the comment:

I see your point now. Since RS is not whitespace by any definition I knew of
previously, why is RS.isspace True?

Apparent answer: Doc says '''Return true if there are only whitespace
characters in the string and there is at least one character, false otherwise.
Whitespace characters are those characters defined in the Unicode character
database as “Other” or “Separator” and those with bidirectional property being
one of “WS”, “B”, or “S”.''' I suspect this is a more expansive definition than
WSpace chars, which seems to be the one used by int(), but you could check the
int code.

Bytes docs says: "Whenever a bytes or bytearray method needs to interpret the
bytes as characters (e.g. the is...() methods, split(), strip()), the ASCII
character set is assumed (text strings use Unicode semantics)."

This says to me that str.isxxx and bytes.isxxx should match on ascii chars and
not otherwise. That would happen is the bytes methods check for all ascii and
decoded to unicode and used str method. Since they do not match, bytes must do
something different.

I think there is one definite bug: the discrepancy between str.isspace and
bytes.isspace. There is possibly another bug: the discrepancy between
'whitespace' for str.isspace and int/float. After pinning down the details, I
think you should ask how to resolve these on py-dev, and which versions to
patch.

[issue18236] int() and float() do not accept strings with trailing separators


Alexander Belopolsky added the comment:

It looks like str.isspace() is incorrect.  The proper definition of unicode 
whitespace seems to include 26 characters:

# 

0009..000D; White_Space # Cc   [5] ..
0020  ; White_Space # Zs   SPACE
0085  ; White_Space # Cc   
00A0  ; White_Space # Zs   NO-BREAK SPACE
1680  ; White_Space # Zs   OGHAM SPACE MARK
180E  ; White_Space # Zs   MONGOLIAN VOWEL SEPARATOR
2000..200A; White_Space # Zs  [11] EN QUAD..HAIR SPACE
2028  ; White_Space # Zl   LINE SEPARATOR
2029  ; White_Space # Zp   PARAGRAPH SEPARATOR
202F  ; White_Space # Zs   NARROW NO-BREAK SPACE
205F  ; White_Space # Zs   MEDIUM MATHEMATICAL SPACE
3000  ; White_Space # Zs   IDEOGRAPHIC SPACE

# Total code points: 26

http://www.unicode.org/Public/UNIDATA/PropList.txt

Python's str.isspace() uses the following definition: "Whitespace characters 
are those characters defined in the Unicode character database as “Other” or 
“Separator” and those with bidirectional property being one of “WS”, “B”, or 
“S”."

Information separators are swept in because they have bidirectional property 
"B":

>>> unicodedata.bidirectional('\N{RS}')
'B'

[issue18282] Ugly behavior of binary and unicode handling on reading unknown encoded files


R. David Murray added the comment:

In python we have a saying that we follow most of the time: if you don't know, 
refuse the temptation to guess.  So currently this is all working as designed: 
you have to know the encoding of the file you are trying to read as unicode.

Adding a 'guess' function that could be called explicitly is a possibility, but 
if we were to go that route we'd probably really want something general to 
guess the encoding of strings, such as (I think) ICU has.  This larger topic is 
a topic more suited to python-ideas, probably followed, if response is 
positive, by a PEP.

So I'm closing this issue as rejected, but feel free to bring it up on 
python-ideas.  (Search for existing threads about it first, please.)

Maybe you need to do a 'make clean' and rebuild?  Our Makefile ought to have a 
target that just throws away the build dir, instead of throwing away the 
checked out software as well, but it doesn't.  So instead of make clean you 
might want to try just deleting the build dir and rebuilding first.

R. David Murray added the comment:

Oh, right, the advocacy howto was deleted recently.  So it is almost certainly 
your stale pickles in the build dir that are the issue.

[issue17621] Create a lazy import loader mixin


Brett Cannon added the comment:

So the approaches I have been using make a loader lazy, so what you have to 
change in terms of sys.meta_path, sys.path_hooks, etc. would very from loader 
to loader.

I have realized one tricky thing with all of this is that importlib itself 
inspects modules post-import to verify that __loader__ and __package__ have 
been set. That typically triggers an immediate load and so might need to be 
special-cased.

2013-06-22 Thread Jon Irenicus


Jon Irenicus added the comment:

The problem is when i run my python script, it somehow slows the whole computer 
down.
I checked my cpu usage, ram usage and disk usage, but nothing comes up.
The script isn't big, it's only about 10kb big.

[issue18286] Python 3.3 - Slowing down computer

2013-06-22 Thread Antoine Pitrou


Antoine Pitrou added the comment:

We can't make anything useful of such a bug report. At a minimum, please post 
your entire script and explain how you are running it. Also explain what your 
system configuration is (operating system, etc.).

That said, it's highly unlikely that Python is responsible for slowing your 
computer down *after* it has finished running.

[issue17621] Create a lazy import loader mixin


Brett Cannon added the comment:

I have attached the test suite and two versions: one using a mixin and one 
using a proxy. Neither solve the issue of import touching the module in any way 
to check __loader__ and __package__. The mixin version is also failing one test 
which could quite possibly be a pain to fix and so it might cause me to prefer 
the proxy solution.

I am not sure what you mean by 'rollback'. My experience and understanding is 
that once I start a merge, I must finish it somehow before doing anything else. 
Do you mean revert a particular problematic file (like NEWS), and hand edit?

STINNER Victor added the comment:

Here is an initial attempt: set a custom allocator for bz2, lzma and zlib 
modules. The allocator is only replaced for an instance of a compressor or 
decompress, the change does not affect the library globally.

PyMem_RawMalloc() is used instead of PyMem_Malloc() because the GIL is always 
released.

tarfile.filemode alias with deprecation warning.

> I would like to replace them with values from the stat module

I would prefer to simply drop all these constants. None is used by the tarfile 
module. *If* an application uses tarfile to get stat constants, this 
application must be fixed to use the stat module which contain thse constants 
since the creation of the stat module, something like 23 years ago...

@Christian: Can you please review this commit?

By the way, mode_t is also defined in import.c:

#ifdef MS_WINDOWS
/* for stat.st_mode */
typedef unsigned short mode_t;
/* for _mkdir */
#include 
#endif

And stat_filemode() should detect integer overflow. mode_t is a 32-bit unsigned 
integer on Linux, and now a 16-bit integer on Windows, whereas stat_filemode() 
uses an unsigned long (which 32 bit on Windows, and 32 or 64 bits on Linux).
