[issue28871] Destructor of ElementTree.Element is recursive

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

Changes were reverted by 78bf34b6a713.

It is very uneasy to implement an alternative mechanism (without increasing the 
size of Element objects). It adds duplication of low level garbage collecting 
code. I think it is better to left all as is in 2.7. Yet one argument for 
moving to Python 3.

[issue29258] __init__.py required for pkgutil.walk_packages in python3

[Anthony Sottile]

New submission from Anthony Sottile:

PEP420 makes __init__.py files optional: 
https://docs.python.org/3/whatsnew/3.3.html#pep-420-implicit-namespace-packages

Though it seems without them, pkgutil.walk_packages does not function as 
desired: https://docs.python.org/3/library/pkgutil.html#pkgutil.walk_packages

Consider the following example:

```
$ tree foo
foo
├── bar
│   ├── baz.py
│   └── __init__.py
├── __init__.py
└── womp.py
```

And a test script

# test.py
```
import pkgutil

import foo


for _, mod, _ in pkgutil.walk_packages(foo.__path__, foo.__name__ + '.'):
print(mod)
```

In both python2 and python3 I get the following output:

```
$ python2.7 test.py
foo.bar
foo.bar.baz
foo.womp
$ python3.5 test.py
foo.bar
foo.bar.baz
foo.womp
```

Removing the __init__.py files and only using python3, I get this:

```
$ find -name '__init__.*' -delete
$ python3.5 test.py
foo.bar
```

The modules are definitely importable:

```
$ python3.5 -c 'import foo.bar.baz'
$
```

[issue18378] locale.getdefaultlocale() fails on Mac OS X with default language set to English

[Nick Coghlan]

Nick Coghlan added the comment:

SSH environment forwarding will propagate this "LC_CTYPE=UTF-8" setting from 
Mac OS X clients to Linux servers.

At present, that breaks in multiple ways, as CPython will interpret it as being 
the "C" locale (since Linux servers don't offer a "UTF-8" locale, even when 
they do offer "C.UTF-8")

PEPs 538 and 540 aim to help CPython itself to deal with that case, but that 
won't be sufficient to help code that tries to pass the nominal LC_CTYPE 
setting to the locale module.

Accepting "UTF-8" and interpreting it as functionally equivalent to C.UTF-8 
will mean that this setting will at least work as desired on servers that offer 
C.UTF-8.

[issue29257] Possible error in discussion of Abstract Base Classes and abstract properties

[Gerald Britton]

New submission from Gerald Britton:

I was rereading the 2.7 docs  about abstract base classes the other day.  I 
found this:

"This defines a read-only property; you can also define a read-write abstract 
property using the ‘long’ form of property declaration:"

along with an example.  so I copied the example and put in a little surrounding 
code:


from abc import ABCMeta, abstractproperty

class C:
__metaclass__ = ABCMeta
def getx(self): pass
def setx(self, value): pass
x = abstractproperty(getx, setx)
 
class D(C):
@property
def x(self):self._x
 
d = D()
print(d)   

When I ran this, I expected an exception, since I defined a read/write abstract 
property but only implemented the read operation.  However, the example runs 
fine. That is the class D can be instantiated without error.  Of course I 
cannot set the property since I didn't implement that part.

Now, If I don't implement the property at all, I can' instantiate the class.  I 
get:

"TypeError: Can't instantiate abstract class D with abstract methods x"

which is what I would expect.  What I don't understand is why I don't get a 
similar error when I implement the read operation for the property but not the 
write operation.

If this actually doesn't work (catching the non-implementation at instantiation 
time), then why is it documented this way?  To me at least the doc implies that 
it *will* raise on the missing write property implementation.

If ABCs are working as intended, can the documentation be changed to reflect 
that as per my experience above?  If the documentation is correct, can the ABC 
implementation be modified to function that way?

[issue23407] os.walk always follows Windows junctions

[Eryk Sun]

Eryk Sun added the comment:

I simply listed the tags that have the name-surrogate bit set out of those 
defined in km\ntifs.h. 

To keeps things simple it might be better to only include Microsoft tags (i.e. 
bit 31 is set). That way we don't have to deal with REPARSE_GUID_DATA_BUFFER 
struct that's used from non-Microsoft reparse points.

[issue29256] Windows select() errors out when given no fds to select on, which breaks SelectSelector

[Nathaniel Smith]

New submission from Nathaniel Smith:

If SelectSelector.select() is called when there are no fds registered, then it 
ends up calling select.select([], [], [], timeout).

On sensible operating systems, this is equivalent to time.sleep(timeout). On 
Windows, it raises an error. Asyncio manages to avoid hitting this due to the 
fact that it always has at least one fd registered, but it causes problems for 
other users of the selectors module, e.g.:
  https://github.com/dabeaz/curio/issues/75

I see two possible approaches to fixing this:

1) Modify SelectSelector to check for this case and call time.sleep() instead 
of select.select() when encountered.

2) Modify the select.select() wrapper so that it behaves consistently on all 
operating systems, by special-casing this situation on Windows.

Option (2) seems nicer to me.

[issue29255] selects.KqueueSelector behaves incorrectly when no fds are registered

[Nathaniel Smith]

New submission from Nathaniel Smith:

When calling kevent(), selectors.KqueueSelector.select sets the "maxevents" 
argument to len(self._fd_to_key). So if there are no fds registered, it passes 
maxevents=0.

It turns out that the kevent() API has a special case behavior for maxevents=0: 
it returns immediately, ignoring timeout. I have no idea why kevent() works 
this way, but it's specifically called out in the man page:

   The nevents argument determines the size of eventlist.  When
   nevents is zero, kevent() will return immediately even if there is a
   timeout specified unlike select(2).

https://www.freebsd.org/cgi/man.cgi?query=kqueue=2

It happens that asyncio doesn't run into this because asyncio always has at 
least one fd registered with its selector, but this causes problems for other 
users of the selectors module, e.g.:
  https://github.com/dabeaz/curio/issues/156

I believe fix would just be to add some code like: "if max_ev == 0: max_ev = 1" 
to selectors.KqueueSelector.select.

[issue23407] os.walk always follows Windows junctions

[Craig Holmquist]

Craig Holmquist added the comment:

Can you point me toward any documentation on the additional tags you want to 
support?  Searching for IO_REPARSE_TAG_IIS_CACHE mostly seems to yield header 
files that define it (and nothing at all on MSDN), and the non-Microsoft tags 
just yield a few results each.

(For comparison, the junction and symbolic link tags yield 10K+ results each.)

Junctions are created with each user's home directory so they exist on every 
Windows system, even if the user never explicitly creates them.  The additional 
tags seem like they're far less common and much less well-documented.

[issue29212] Python 3.6 logging thread name regression with concurrent.future threads

[desbma]

desbma added the comment:

Thoughts anyone?

This is a minor bug, but for a common use case (easy to hit), and the fix is 
trivial.

[issue29254] Documentation Error

[Ammar Askar]

Ammar Askar added the comment:

Given `slice[start:end]`:

What this line is trying to say is that the slice index is inclusive for the 
start parameter and exclusive for the end parameter.

In mathematical/interval notation this would look like [start, end)

As a quick example look at the word "Python"
Index  012345
Letter Python

If you do word[:2], the result is 'Py', notice how the t is excluded.

[issue29254] Documentation Error

[Suraj Kumar]

New submission from Suraj Kumar:

Hi,

I have found one documentation mistake in section 3.1.2. Strings saying
"""Note how the start is always included, and the end always excluded. This 
makes sure that s[:i] + s[i:] is always equal to s:
>>>word = 'Python'
>>> word[:2] + word[2:]
'Python'
"""

I think instead of 'the end always excluded' it should be 'the end always 
included'.

If my observation is correct, please do the needful change.

Thanks & Regards,
Suraj

I think Ronald's patch issue18378-2015-07-25-py36.txt with added darwin check

In the current form, it would allow using 'UTF-8' as locale string on all

[issue25658] PyThread assumes pthread_key_t is an integer, which is against POSIX

[Erik Bray]

Erik Bray added the comment:

Thanks Masayuki for the updated patch, and especially for the additional test 
cases.

Looking at the patch, it occurs to me that this solution seems to be the 
minimal needed to fix the issue that we were originally trying to fix, without 
adding too much additional complexity or new semantics to how TLS keys are used 
in the interpreter.  In other words, this preserves the existing usage with 
minimal changes except to better support opaque key types.  So I think it's a 
point in favor of this change that's managed to remain focused.

I'll work on updating the PEP draft to reflect the additions.

[issue29253] Fix test_asyncore tests on Cygwin

[Erik Bray]

New submission from Erik Bray:

This patch works around a couple different problems with running the 
test_asyncore tests in Cygwin, both of which are due to bugs in Cygwin itself 
and not in Python.  As such, I don't think Python should try to work around 
these issues in general, but I do think they're worth at least working around 
in the tests so that they can pass and/or skip.

The first issue is more severe, as it actually causes the test run to hang 
indefinitely due to a bug in Cygwin that can cause connect() on a socket to 
block indefinitely.  This occurs only in a situation where a "client" connects 
to a "server" that is not accept()-ing connections--a situation that occurs 
specifically in some of the asyncore tests where both the "client" and the 
"server" are in the same test process.  This applies a known workaround to the 
tests only, allowing them to pass.

The other bug simply causes a test failure--the bug is that 
getsockopt(SO_REUSEADDR) returns the wrong result after a 
setsockopt(SO_REUSEADDR) (the latter has the correct behavior; the value of the 
option just isn't reported back correctly after being set).  In this case the 
relevant test is simply skipped on Cygwin.

The patch is currently light on in-line documentation of the situation, but I 
can add that if it's otherwise approved.

[issue29240] Implementation of the PEP 540: Add a new UTF-8 mode

[STINNER Victor]

STINNER Victor added the comment:

Patch version 4:

* Handle PYTHONLEGACYWINDOWSFSENCODING: this env var now disables the UTF-8 
mode and has the priority over -X utf8 and PYTHONUTF8
* Add an unit test on PYTHONUTF8 env var and -E cmdline option
* Add an unit test on the POSIX locale
* Fix initstdio() to handle correctly empty PYTHONIOENCODING: this bug affects 
Python 3.6 as well and is not directly related to the PEP 540
* Fix to handle correctly PYTHONUTF8 set to an empty string (ignore it)
* Skip an unit test in test_utf8mode which failed with the POSIX locale

Note: This patch still has the sys.argv encoding bug with locale encodings 
different than ASCII and UTF-8.

[issue29176] /tmp does not exist on Android and is used by curses.window.putwin()

[STINNER Victor]

STINNER Victor added the comment:

The putwin() function uses mkstemp() with the path template 
/tmp/py.curses.getwin.XX.

I would prefer to use the Python function tempfile.mkstemp(). This function has 
a more portable behaviour. For example, Python is able to atomatically make the 
file descriptor non-inherirable if the OS supports this feature.

I suggest to expect a file descriptor in the C putwin() and write a Python 
putwin() which expects a file and pass file.fileno() if available, or use 
tempfile.TemporaryFile().

tempfile.TemporaryFile is even more secure because the file is not accessible 
from the regular file system on most platforms. This function is able to use 
the secure Linux O_TMPFILE flag and the O_TEMPORARY flag on Windows.

[issue18378] locale.getdefaultlocale() fails on Mac OS X with default language set to English

[Wolfgang Maier]

Wolfgang Maier added the comment:

I think PEP 538 extended to the UTF-8 locale *would* help here. Specifically, 
it would coerce only LC_CTYPE to en_US.UTF-8 (unless OS X has C.UTF-8), which I 
guess is good enough for the purpose here.

I do agree that it is not the kind of problem that PEP 538 tries to solve right 
now, but it could be extended to cover other types of problematic locales like 
this one. Just wanted to make you aware of this possibility.

[issue18378] locale.getdefaultlocale() fails on Mac OS X with default language set to English

[Nick Coghlan]

Nick Coghlan added the comment:

PEP 538 wouldn't help here, as there's nothing wrong with CPython's assumptions 
about the text encoding to use for operating system interfaces - it's assuming 
UTF-8 (because it's Mac OS X) and that assumption is correct (because it's Mac 
OS X).

The problem appears to be that locale.py was written primarily for Linux, and 
hence makes assumptions that aren't valid on BSD and Mac OS X.

Dmitry's suggested solution of taking the BSD/Mac OS X specific locale of 
"UTF-8" and universally accepting it as meaning (None, "UTF-8") sems like a 
sensible step forward, even if it doesn't resolve all the discrepancies.

Where PEP 538 and PEP 540 would come into play is when this setting gets 
forwarded over SSH to Linux servers (as then CPython *will* get the nominal 
system text encoding wrong), but that's independent of getting the locale 
module to handle it more gracefully.

[issue29252] self in classes missinterpreted as a string.

[Decorater]

New submission from Decorater:

So, I have a class (it subclasses the zipimporter for my import hook) that 
allows me to not worry about issues when the hook is appended to the beginning 
of the path hooks.

The code to the class as follows:

class OriginalZipImport(zipimport.zipimporter):
"""
Original zipimporter class. Modified for requirements of this import hook.
"""
# Sadly I have to manually specify the file extensions the original
# zipimporter supports to bypass an AttributeError.
# according to https://docs.python.org/3.6/library/zipimport.html
# zipimport only allows importing ``.py`` and ``.pyc`` files from zips.
extensions = ['.py', '.pyc']

def __init__(self, archivepath):
super(OriginalZipImport, self.inst).__init__(self, archivepath)

def find_loader(self, fullname, path=None):
"""
Original find_loader.
"""
self.inst.find_loader(fullname, path=path)

def find_module(self, fullname, path=None):
"""
Original find_module.
"""
self.inst.find_module(self, fullname, path=path)

def load_module(self, fullname):
"""
Original load_module.
"""
self.inst.load_module(self, fullname)

However instead of working like the way I would expect it gives this traceback:

Traceback (most recent call last):
  File "E:\Users\Elsword\Desktop\DecoraterBot\Async\\zipmaker\make_zip.py", 
line 11, in 
from pathlib import Path
  File "", line 961, in _find_and_load
  File "", line 946, in _find_and_load_unlocked

 line 180, in find_loader
self.inst.find_loader(fullname, path=path)
AttributeError: 'str' object has no attribute 'inst'

Note: it does use a slightly modified make_zip.py that is different than the 
one that is on the python source trees. It is specifically for testing the hook 
to see if it works or not.

The hook is supposed to work however it is confusing why it is doing this as I 
did not set self to be an string so it should allow me to do all of this just 
fine.

[issue18235] _sysconfigdata.py wrong on AIX installations

[Michael Felt]

Michael Felt added the comment:

The "key" bit of the patch is to move the code AND make this assignment:

if _PYTHON_BUILD:
vars['LDSHARED'] = vars['BLDSHARED']

Besides, imho, skipping around the problem that LDSHARED is not correctly 
assigned - it cannot work because BLDSHARED is not set to the 'installed' value.

And, frankly I am amazed (in Python3-3.6.0) both are equal AND both pointing at 
the 'installed' location.

OOPS: I just looked and the patch above is NOT in the Python3-3.6 branch, and 
as both variables are identical now in _sysconfigdata_m_aix5.py - neither 
assignment has any affect.

Again: comparing python2 and python3 it seems the latest Python3 now have the 
fullpath - and equal definitions - for both variables WHILE Python2 use 
'relative' pathnames - BUT both are equal.

As far as the patch goes - it is irrevalant and can be removed in Python3 while 
a quick hack for Python2 would be to use (in the new location!)

if _PYTHON_BUILD:
vars['LDSHARED'] = vars['LDCXXSHARED']

[issue29251] Class __dict__ is only a mapping proxy

[Martin Panter]

New submission from Martin Panter:

The __dict__ attribute of class objects is documented as being a (standard) 
dictionary, but implemented with a proxy object. I propose to clarify the 
documentation in “Custom classes” under 
,
 and in .

I believe my changes are also applicable to Python 2, as long as I point out 
the proxy is specific to “new-style” classes.

[issue29176] /tmp does not exist on Android and is used by curses.window.putwin()

[Xavier de Gaye]

Xavier de Gaye added the comment:

The test suite runner in the test.libregrtest.main module calls 
tempfile.gettempdir() and mkstemp_curses.patch uses the same logic to fix the 
problem on Android where the tests that I run use TMPDIR=/data/local/tmp on 
Android API 24.

As a side note, when the curses library is ncurses-6.0, the library must be 
patched in ncurses/base/lib_screen.c with the attached ncurses.patch, see:

[issue29249] Pathlib glob ** bug

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

** is supported not just as a prefix. Path('./Lib').glob('**/*.py') emits the 
same paths as Path('.').glob('Lib/**/*.py'). But ** is supported only in 
glob(), not in match(). The support of ** in match() is not documented. Would 
be worth to document explicitly that it is not supported.

[issue28759] access to mkfifo, mknod and hard links is controled by SELinux MAC on Android

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

The purpose of this helper is skipping the test rather than failing if some OS 
operation is not permitted by current configuration. May be 
skip_if_not_permitted()?

Similar helpers that convert runtime error in skipping a test: import_module(), 
get_attribute(), bind_unix_socket(), system_must_validate_cert(). They are more 
concrete, guard some specific operation.

Context manager is not the only possible syntax. The helper can call a function:

helper(os.mkfifo, filename)

or be a wrapper:

helper(os.mkfifo)(filename)

If you prefer such syntax.

There are many possibilities, and I think it is worth to discuss this on 
Python-Dev.

[issue27632] build on AIX fails when builddir != srcdir, more than bad path to ld_so_aix

[Michael Felt]

Michael Felt added the comment:

> Regarding reopening Issue 10656, whatever you think is more appropriate. 

Not "scary", just irritating. I'll open a new one when I have more time to 
document it.

> Issue 16189 and Issue 25825 were about updating to match recent changes to

My bad. I was looking at the subject titles (cannot load ld_so_aix, cannot 
build external modules). I'll focus on the 'patch' you mention below. As it 
stands, I have no idea how to determine if they have any relevance to 
anything...

> Regarding LDSHARED vs BLDSHARED, isn’t this the same as Issue 28311, which

Will do.

[issue18235] _sysconfigdata.py wrong on AIX installations

[Michael Felt]

Michael Felt added the comment:

OK - just looked at what happens with Python3-3.6

new file name: _sysconfigdata_m_aix5_.py

values:
root@x064:[/data/prj/python/python3-3.6.0/X64/opt/lib/python3.6]grep SHARED 
_sysconf*.py | grep LD
 'BLDSHARED': '/opt/lib/python3.6/config-3.6m/ld_so_aix xlc_r '
 'LDCXXSHARED': '/opt/lib/python3.6/config-3.6m/ld_so_aix xlc_r '
 'LDSHARED': '/opt/lib/python3.6/config-3.6m/ld_so_aix xlc_r '


The 'build' worked, so I am guessing that BLDSHARED had a different value that 
what it shows here. 

The full pathname for ld_so_aix is correct.

As I mentioned in https://bugs.python.org/issue28311#msg277692 - still broken 
for Python2-2.7(.13) - shall try your patch above (once I figure out how to 
grab it)

'supported_operation':
* The intent in using 'supported' was that the context manager could possibly 
be extended later.
* 'operation' is the terminology used in the GNU libc documentation [1].
I will replace 'supported_operation' with 'permitted_operation' unless a better 
name is proposed.

[issue23407] os.walk always follows Windows junctions

[Eryk Sun]

Eryk Sun added the comment:

I opened issue 29248 for the os.readlink bug and issue 29250 for the 
inconsistency between os.path.islink and os.stat.

Handling junctions as links is new behavior, so I've changed this issue to be 
an enhancement for 3.7.

If the notion of a link is generalized to junctions, then maybe it should be 
further generalized to include all name-surrogate reparse tags [1]. Currently 
for Microsoft tags this includes 

IO_REPARSE_TAG_MOUNT_POINT (junctions)
IO_REPARSE_TAG_SYMLINK
IO_REPARSE_TAG_IIS_CACHE

For non-Microsoft tags it includes 

IO_REPARSE_TAG_SOLUTIONSOFT
IO_REPARSE_TAG_OSR_SAMPLE
IO_REPARSE_TAG_QI_TECH_HSM
IO_REPARSE_TAG_MAXISCALE_HSM

The last two are outliers. HSM isn't the kind of immediate, fast access that 
one would expect from a symbolic link. All other HSM tags aren't categorized as 
name surrogates.

The patch for Issue 26228 proposes an improvement to the situation, although it 
is not perfect and does not include a test. I wonder if it is possible to 
replace fork() and execlp() with a subprocess.Popen invokation, at least in a 
new Python release?

[issue29250] islink and stat follow_symlinks are inconsistent on Windows

[Eryk Sun]

New submission from Eryk Sun:

win32_xstat_impl in Modules/posixmodule.c doesn't check the value of 
reparse_tag to limit traversal to only tags that are considered links. So we 
have cases in which os.path.islink returns False (e.g. junctions, pending the 
resolution of issue 23407), but os.stat and os.lstat disagree. For example:

>>> os.path.islink(r'C:\Documents and Settings')
False
>>> s = os.stat(r'C:\Documents and Settings')
>>> ls = os.lstat(r'C:\Documents and Settings')
>>> s.st_ino == ls.st_ino
False

At its strictest, traversal would be limited to just symbolic links. It could 
be relaxed to also include junctions, and even further to include all tags with 
the name surrogate bit set [1]. This includes the following Microsoft tags

IO_REPARSE_TAG_MOUNT_POINT (junctions)
IO_REPARSE_TAG_SYMLINK
IO_REPARSE_TAG_IIS_CACHE

and non-Microsoft tags: 

IO_REPARSE_TAG_SOLUTIONSOFT
IO_REPARSE_TAG_OSR_SAMPLE
IO_REPARSE_TAG_QI_TECH_HSM
IO_REPARSE_TAG_MAXISCALE_HSM

I'm creating this issue as an enhancement for 3.7. The problem has existed for 
a long time, but it hasn't been a thorn in anyone's side as far as I know.

I'm trying to implement that, but it's hard to factorize the code. I will 
probably have to duplicate the code handling -E, -X utf8, PYTHONMALLOC and 
PYTHONUTF8 for wchar_t* (UCS4 or UTF-16) and char* (bytes).

[issue29006] 2.7.13 _sqlite more prone to "database table is locked"

[Gian-Carlo Pascutto]

Gian-Carlo Pascutto added the comment:

>Then we wait for someone that really knows why the change was done in the 
>first place.

Python 2.7 had a regression compared to 2.6 where a SELECT after a COMMIT would 
silently return the wrong data:

http://bugs.python.org/issue23129
http://bugs.python.org/issue10513

Neither exiting with a locked error nor producing the wrong data are 
particularly appealing results. Did 2.6 pass those sets that caused the 
attempted fix to get backed out?

[issue29248] os.readlink fails on Windows

[Eryk Sun]

New submission from Eryk Sun:

win_readlink in Modules/posixmodule.c mistakenly treats the PrintNameOffset 
field of the reparse data buffer as a number of characters instead of bytes. 
Thus, if the offset is non-zero, the value returned is incorrect stack garbage. 
For example, the following should return "C:\\ProgramData":

>>> os.readlink(r'C:\Users\All Users')
'\u6c20\u3012\u041f\x01\u2768\u60b2\u031b\x02\x05\x00\u031e\x06\u8c01\u4012'

Craig Holmquist found this bug, as detailed in message 277385. He included a 
fix in the patch for issue 23407, but this should be addressed in the next 
maintenance release of 3.5 and 3.6.
