[issue16724] Rename `data` argument names to `bytes`

[Amaury Forgeot d'Arc]

Amaury Forgeot d'Arc added the comment:

Why? The binascii module consistently uses "data" to refer to binary data. For 
example: 
"Return the hexadecimal representation of the binary data. Every byte of data 
is converted ..."

[issue16723] io.TextIOWrapper on urllib.request.urlopen terminates prematurely

[Amaury Forgeot d'Arc]

Amaury Forgeot d'Arc added the comment:

Hum, io objects are not supposed to close themselves when they run out of data.
Even if HTTPResponse chooses to close the underlying socket (to clean unused 
resources?), it should not report itself as a closed io.IOBase.
Subsequent calls read() should return b"", this is the io.RawIOBase way to 
indicate EOF.

To fix this particular example, it seems enough to delete the "@property def 
closed(self)" from HTTPResponse. Note the XXX just above:
"""
# XXX This class should probably be revised to act more like
# the "raw stream" that BufferedReader expects.
"""
But close() should be modified as well, and internal calls to close() should be 
changed to only close the underlying socket.

[issue16726] expat ParseFile expects bytes, not string

[Michiel de Hoon]

New submission from Michiel de Hoon:

The expat parser in xml.parsers.expat has a Parse method and a ParseFile 
method. The Parse method parses a string, however the ParseFile method wants 
bytes.

This is a minimal example of the Parse method:

>>> import xml.parsers.expat
>>> p = xml.parsers.expat.ParserCreate()
>>> p.Parse('')

which runs fine. Note that argument to p.Parse is a string, not bytes.

This is the corresponding example of ParseFile:

>>> import xml.parsers.expat
>>> handle = open("test.xml")
>>> p = xml.parsers.expat.ParserCreate()
>>> p.ParseFile(handle)

where the file test.xml only contains 
This gives an error:

Traceback (most recent call last):
  File "", line 1, in 
TypeError: read() did not return a bytes object (type=str)

Opening the file test.xml in binary raises an Error:

>>> import xml.parsers.expat
>>> handle = open("test.xml", "rb")
>>> p = xml.parsers.expat.ParserCreate()
>>> p.ParseFile(handle)
Traceback (most recent call last):
  File "", line 1, in 
xml.parsers.expat.ExpatError: no element found: line 2, column 0

suggesting that in reality, the expat Parser needs a string, not bytes.
(the same error appears with a more meaningful XML file).

I would expect that both Parse and ParseFile accept strings, but not bytes.

The bug affects me on python 2.7, as described by the original reporter.

I am using Ubuntu 12.04 which comes with python 2.7.3 - was this fixed for 2.7 
quite recently?

However the python 3.2 that is packaged for Ubuntu 12.04 does not suffer from

The Windows x86-64 MSI Installer (2.7.3) installs a 64 bit python27.dll in 
windows\system32, NOT in windows\SysWOW64 as it should.

The python27.dll should be kept in the python DLLs directory for both 32 and 64

__getitem__ and __len__ are required for sequence type.
(__iter__ is not required because types having __getitem__ are already 
iterator.)

.__contains__(), .index() and .count() is not required for sequence.

For example, following class should be sequence.

class Foo:

if not isinstance(index, int):
raise TypeError
if index >= 3:
raise IndexError

[issue16729] Document how to provide defaults for setup.py commands options

[anatoly techtonik]

New submission from anatoly techtonik:

The way to override defaults for setup.py commands is not documented. For 
example, to change to name of build and dist dirs from setup.py, the following 
entry should be added to setup parameters:

options={
'build': {'build_base': '__build__'},
'sdist': {'dist_dir': '__build__/dist'},
}

[issue16730] _fill_cache in _bootstrap.py crashes without directory execute permissions

[David Pritchard]

New submission from David Pritchard:

In importlib/_bootstrap.py, there is a function _fill_cache which crashes when 
you try to run Python in any environment that is so restricted that write 
permissions are not allowed. You get a trace like:

Traceback (most recent call last):
  In line:
[the import statement]
  File "", line 1558, in _find_and_load
  File "", line 1516, in _find_and_load_unlocked
  File "", line 1470, in _find_module
  File "", line 1305, in find_module
  File "", line 1284, in _get_loader
  File "", line 1356, in find_loader
  File "", line 1392, in _fill_cache
PermissionError: [Errno 13] Permission denied: '[the directory name]'

This was not an issue when I was using Python 3.2 and I suspect it has to do 
with the OS error refactoring. I believe it can be fixed with a two-line patch, 
attached. (Sorry if it is the wrong format, it's the first one I've submitted.) 
The patch simply treats the case of PermissionError the same was as it does 
when there is a FileNotFoundError. I've tested the patch and it fixes the 
problem.

[issue15533] subprocess.Popen(cwd) documentation

[Jan Lachnitt]

Jan Lachnitt added the comment:

Hi all,

I have solved the problem by using absolute path of the executable. The reason 
why the executable didn't work properly may be that the executable's relative 
path was inconsistent with current directory. See the following example (I have 
made an executable which shows its argv and cwd). If it is called normally, 
then:

argv[0] = phsh0.exe
cwd = D:\Jenda\AutoLEED\TESTING\default

But if it is called by Python's subprocess.call from 
"D:\Jenda\AutoLEED\TESTING" as I want, then:

argv[0] = default\phsh0.exe
cwd = D:\Jenda\AutoLEED\TESTING\default

The executable may be confused by this inconsistency. So it is not the 
documentation, but Python itself what should be changed. The executable should 
be searched in cwd on any platform to avoid the inconsistency.

I have not yet updated my Python installation, so my results apply to 3.2.3.

[issue16724] Rename `data` argument names to `bytes`

[anatoly techtonik]

anatoly techtonik added the comment:

In Python 2 there was no 'binary data' type - everything was a string. Now we 
have string, str, bytearray, array, list of ints. If hexlify is not accepting 
anything except bytes, it is better be explicit.

When porting code from Python 2 the argument was passed as a string with 
escapes inside, so it took some time to figure out why it didn't work in Py3k 
(actually it took a lot of time, because the research path turned wrong way at 
this point).

[issue13153] IDLE crashes when pasting non-BMP unicode char on UCS-16 build

[Chris Angelico]

Chris Angelico added the comment:

I'm experiencing a similar issue. Fresh install of 3.3 today from the .msi 
installer on the web site, identifies itself as:
Python 3.3.0 (v3.3.0:bd8afb90ebf2, Sep 29 2012, 10:55:48) [MSC v.1600 32 bit 
(Intel)] on win32

To reproduce: Copy and paste this character into IDLE. 𝐇

C:\Python33>.\python -m idlelib.idle
Traceback (most recent call last):
  File "C:\Python33\lib\runpy.py", line 160, in _run_module_as_main
"__main__", fname, loader, pkg_name)
  File "C:\Python33\lib\runpy.py", line 73, in _run_code
exec(code, run_globals)
  File "C:\Python33\lib\idlelib\idle.py", line 11, in 
idlelib.PyShell.main()
  File "C:\Python33\lib\idlelib\PyShell.py", line 1477, in main

self.tk.mainloop(n)
UnicodeDecodeError: 'utf-8' codec can't decode bytes in position 0-2: invalid 
continuation byte


(Incidentally, there appears to be a slight difference depending on whether I 
copy the character in Chrome or Firefox. IDLE terminates the same way, but a 
Latin-1 app sees the character from Firefox as a letter, but the same thing 
from Chrome is two question marks (presumably the surrogates).)

[issue16728] collections.abc.Sequence shoud provide __subclasshook__

[INADA Naoki]

INADA Naoki added the comment:

I think PySequence_Check() has same problem.

OTOH, mapping definition says:

> A container object that supports arbitrary key lookups and implements the 
> methods specified in the Mapping or MutableMapping abstract base classes.
- http://docs.python.org/3.3/glossary.html#term-mapping

So the mapping should implement all methods defined in collections.abc.Mapping.

If the sequence should implement all methods defined in 
collections.abc.Sequence, it's a documentation bug.

Is there a common view about what is the sequence?

R. David Murray added the comment:

We do not use data type names as formal parameter names.  You will realize this 
is sensible if you consider that in most cases in Python the formal parameter 
name is something gets used in more than just the documentation, and that using 
a type name would shadow the type name, which is something we prefer to avoid.

[issue16076] xml.etree.ElementTree.Element and xml.etree.ElementTree.TreeBuilder are no longer pickleable

[Daniel Shahaf]

Daniel Shahaf added the comment:

Re the problem from msg 177134 ('./python -mtest test___all__ test_xml_etree' 
failing), it is a a preexisting problem, in the sense that applying just the 
Lib/test/ part of this patch suffices to trigger it.  Adding 'xml.etree' to the 
blacklist in test___all__.py:50 suffices to address the problem.  At a guess 
that is because when test___all__ imports the 'xml.etree' module, it doesn't 
filter out the '_elementtree' symbol like test_xml_etree.py:test_main() does.

New patch attached; differences to previous version:

- Removed debug prints.
- Skip test_pickling when testing the Python xml.etree.
  (The skips could be removed in the future, if/when the test___all__
  interaction problem is resolved.)

[issue16718] Mysterious atexit fail

[Amaury Forgeot d'Arc]

Amaury Forgeot d'Arc added the comment:

Infortunately, the behaviour is the same in 2.7 and 3.2, and only changes with 
3.3, which means that this is probably related to the new implementation of the 
import system.
This won't be backported.

[It would be interesting to understand why there is a difference, btw... is a 
reference to the module held somewhere?]

A possible workaround for such module-level calls atexit.register() is to 
ensure that used globals are captured in the function namespace, a bit like 
some __del__ methods:

[issue16718] Mysterious atexit fail

[Amaury Forgeot d'Arc]

Amaury Forgeot d'Arc added the comment:

OK, found the difference between 3.2 and 3.3:
The ImportError exception is still alive when atexit handlers are called, with 
its __traceback__, and all local variables in Python frames.
And since 3.3 the import system is built with Python functions...

More exactly, I could find the incomplete 'wow' module in 
sys.last_value.__traceback__.tb_next.tb_frame.f_back.f_back.f_back.f_locals['module']

But all this is not really related to the current issue.
Things should be better in the future, when modules are cleared with true 
garbage collection.

When is this future of which you speak?

I am not sure whether it would affect performance, but a weakrefable subclass 
of dict could be used for module dicts.  Then the module destructor could just 
save the module's dict in a WeakValueDictionary keyed by the id (assuming we 
are not yet shutting down).  At shutdown the saved module dicts could be purged 
by replacing all values with None.

Or maybe something similar is possible without using a dict subclass.

BTW, Руслан, can you change your name to use latin alphabet?
I'm Андрей Светлов, but use Andrew Svetlov for tracker.
Latin transcription is much easier to remember for all python users who don't 
speak Russian. For that guys your name looks like Chinese one for me.
Thanks.

[issue1075356] exceeding obscure weakproxy bug

[Matthew Barnett]

Matthew Barnett added the comment:

The patch "issue1075356.patch" is my attempt to fix this bug.

'PyArg_ParseTuple', etc, eventually call 'convertsimple'. What this patch does 
is to insert some code at the start of 'convertsimple' that checks whether the 
argument is a weakref proxy and, if it is, fetch the object to which the proxy 
refers. From then on it's working with the true argument, so it'll work just 
like would have done if it been given the proxied object itself originally.

I am aware of that issue, but the original patch is 9 years old.  Which is why 
I ask if/when it will actually happen.

[issue16733] Solaris ctypes_test failures

[yippi]

New submission from yippi:

Note I am building Python 3.3 with the Sun Studio compiler on Solaris 11.  When 
I run the tests, I get these 2 ctypes errors:

==
FAIL: test_ints (ctypes.test.test_bitfields.C_Test)
--
Traceback (most recent call last):
  File 
"/builds/bacamero/ul/components/python/python33/Python-3.3.0/Lib/ctypes/test/test_bitfields.py",
 line 40, in test_ints
self.assertEqual(getattr(b, name), func(byref(b), name.encode('ascii')))
AssertionError: -1 != 1
==
FAIL: test_shorts (ctypes.test.test_bitfields.C_Test)
--
Traceback (most recent call last):
  File 
"/builds/bacamero/ul/components/python/python33/Python-3.3.0/Lib/ctypes/test/test_bitfields.py",
 line 47, in test_shorts
self.assertEqual(getattr(b, name), func(byref(b), name.encode('ascii')))
AssertionError: -32 != 32
--

I see almost identical errors in Python 2.6 and 2.7.  The same two tests fail, 
though the format of the error message is a bit different.  For example it 
looks like this in 2.7:
AssertionError: Tuples differ: ('A', 1, -1) != ('A', 1, 1)
AssertionError: Tuples differ: ('R', 32, -32) != ('R', 32, 32)

I made a simple standalone test program that prints out all the values
instead of stopping on first failure.  The script and output is attached
for reference. 

I think this might be related to issue #16275.  On Solaris 11 we are building 
Python with the configure --with -system-ffi argument.  On Solaris 11, libffi 
3.0.9 is used.  I tried updating libffi to the latest 3.0.11 version and 
rebuilding, but that did not help.

Any pointers about how to debug this would be helpful.  It is not clear to me 
if this is a libffi issue, a compiler issue, a problem in Python or something 
else.  Is there any additional information I could provide to help track this 
down?

[issue16690] Reference leak with custom tp_dealloc in PyType_FromSpec

[Bradley Froehle]

Bradley Froehle added the comment:

The attached file `heaptype_refcnt_testcases.py` runs through several test 
cases (ssl.SSLError, a subclass of ssl.SSLError, and xxlimited.Xxo) seeing if 
references are leaked in each instance.

Unfortunately `xxlimited.Xxo` isn't set to be a base type and I don't know of 
any other types in the default install which use PyType_FromSpec with a custom 
tp_dealloc.

[issue16694] Add pure Python operator module

[Zachary Ware]

Zachary Ware added the comment:

Sorry to have disappeared on this, other things took priority...

Thank you for the comments, Serhiy.  v2 of the patch renames Modules/operator.c 
to Modules/_operator.c, and changes that name every place I could find it.

I also tried to tidy up some of the error message mismatches.  I didn't bother 
with the ones regarding missing arguments, as that would mean checking args and 
throwing an exception in each and every function.

I do like the functional attrgetter better than the object version I wrote.  
The main reason I went with an object version in the first place was because 
that's what the C implementation used.  Is there any reason not to break with 
the C implementation and use a function instead?  The updated patch takes a 
rather ugly hack to try to use the functional version in an object.

length_hint() was horrible and has been rewritten.  It should be less horrible 
now :).  It should also follow the C implementation quite a bit better.

[issue16724] Define `binary data` representation in Python

[Chris Jerdonek]

Chris Jerdonek added the comment:

> It will help if Python docs contained a definition of what can be considered 
> 'binary data' and link this term from hexlify description to this definition.

I believe this is part of the goal of issue 16518, where "bytes-like object" is 
being proposed as one of the terms for addition to the glossary.

[issue16722] __index__() overrides __bytes__() when bytes() is called

[Руслан Ижбулатов]

Руслан Ижбулатов added the comment:

Yes, i saw #15559 ( well, actually, i saw the related discussion 
http://mail.python.org/pipermail/python-dev/2012-August/121241.html ) while 
looking for an answer. It's more narrow - i.e. manifestation of this issue in 
ipaddress case where some people actually _needed_ to have different values 
returned by __index__() and __bytes__(), and had to work around it.

As for my name, my username is used almost everywhere and, unlike my real name, 
it's easy to read and remember. The only place where usernames aren't mentioned 
are mails from the Python issue tracker. File a bug for it.

[issue16694] Add pure Python operator module

[Zachary Ware]

Zachary Ware added the comment:

Considering what a huge headache it was to get my own patch to apply at home on 
Linux rather than at work on Windows, here's a new version of the patch that 
straightens out the line ending nightmare present in v2. No other changes made.

[issue16734] Delay interpreter startup phase until script is read

[anatoly techtonik]

New submission from anatoly techtonik:

Currently, when interpreter is launched it returns immediately to parent 
process without waiting to read the entrypoint script. This causes problem when 
you need to remove this script after executing.

Is it possible to delay return to child process until the entrypoint script is 
read?

See test case in attach.
