[issue33935] shutil.copyfile throws incorrect SameFileError on Google Drive File Stream

[Deniz Bozyigit]

Deniz Bozyigit  added the comment:

Hi, thank you for looking into this. I'm aware that the shown patch is not the 
ideal solution and a mere fix to get my jupyter operational. 

An indication on a workable solution could be the _samefile function in shutil 
that wraps os.path.samefile:

def _samefile(src, dst):
# Macintosh, Unix.
if hasattr(os.path, 'samefile'):
try:
return os.path.samefile(src, dst)
except OSError:
return False

# All other platforms: check for same pathname.
return (os.path.normcase(os.path.abspath(src)) ==
os.path.normcase(os.path.abspath(dst)))


I understand that the implicit platform differentiation that is done here (see 
the comment line) is not valid anymore since os.path.samefile is now available 
on windows systems. It seems that for a windows system the here implemented 
file name comparison could be workable (even moving it into os.path.samefile?), 
if the platform is identified correctly.

[issue33876] doc Mention relevant pythonesque implementations

[Mariatta Wijaya]

Mariatta Wijaya  added the comment:

Thanks for the PR, and thanks everyone for the feedback.

But I don't think we should be the one maintaining a list of all available 
alternative Python implementation out there.

There is already a good list: 
https://wiki.python.org/moin/PythonImplementations which is the top result when 
people search for "Python implementation".

I'm inclined to close this issue.

[issue33905] IDLE: Test stackbrowser.Stackbrowser

[Terry J. Reedy]

Terry J. Reedy  added the comment:

(My initial messages contained a mistaken idea based on a mis-remembering the 
details sys.last values and exceptions.)

If an exception is not caught and a traceback is printed, sys.last_type, 
sys.last_value, and sys.last_traceback are set.  When an exception is caught, 
the last_ x values are not touched, but the same are available by calling 
sys.exc_info.  Stackview accessed all 3 sys.last_x values, but they are not 
normally set when testing because exception are caught.  The test sets them 
from a sys.exc_info after catching an exception.

[issue33936] OPENSSL_VERSION_1_1 never defined in _hashopenssl.c

[Quentin Minster]

New submission from Quentin Minster :

I'm getting a compile error in Modules/_hashopenssl.c because the file uses 
some pre-1.1.0 APIs even though I'm running OpenSSL 1.1.0.

This is because this file doesn't define the OPENSSL_VERSION_1_1 macro, like 
Modules/_ssl.c does.

[issue33935] shutil.copyfile throws incorrect SameFileError on Google Drive File Stream

[Eryk Sun]

Eryk Sun  added the comment:

David, this is a bug in Python, and the proposed patch is insufficient. We use 
the volume serial number as st_dev, and this is not guaranteed to be unique in 
Windows, and may be 0, just as a file's index number is also allowed to be 0. 
Both possibilities are well documented. With a WebDAV volume you will find that 
both numbers are 0. Using the VSN and file index as if they're the same as 
POSIX st_dev and st_ino is technically wrong. There is no guarantee that this 
tuple uniquely identifies a file in Windows.

[issue33935] shutil.copyfile throws incorrect SameFileError on Google Drive File Stream

[R. David Murray]

R. David Murray  added the comment:

That patch would cause references to the same file on a google drive to report 
that the files were different.

I'd say this is a bug in Google Drive's posix emulation.

I'm not sure there's a good answer here, because even if every other element of 
the stat were equal, that wouldn't mean it was the same file: if you use 
copystat as well as copyfile the stats would otherwise be equal.

I think we should close this as a third party bug.

[issue1617161] Instance methods compare equal when their self's are equal

[Josh Rosenberg]

Josh Rosenberg  added the comment:

If [].append == [].append is True in the "unique set of callbacks" scenario, 
that implies that it's perfectly fine to not call one of them when both are 
registered. But this means that only one list ends up getting updated, when you 
tried to register both for updates. That's definitely surprising, and not in a 
good way.

[issue33935] shutil.copyfile throws incorrect SameFileError

[Deniz Bozyigit]

New submission from Deniz Bozyigit :

When using shutil.copyfile on the Google Drive File Stream file system, a 
incorrect SameFileError can occur. 

MWE (assuming foo.txt exists in your google drive G:\\):
>>> f1 = 'G:\\My Drive\\foo.txt'
>>> f2 = 'G:\\My Drive\\foo2.txt'
>>> import shutil
>>> shutil.copyfile(f1, f2)
>>> shutil.copyfile(f1, f2)

--> Last line throws incorrect SameFileError. In comparison, executing the same 
code on a different file system (e.g. local hard drive) will result in no 
errors.

More details described here: https://github.com/jupyter/notebook/issues/3615

The error originates in the library in generalpath.py in the function samestat: 
Google Drive File Stream reports inode==0 which makes os.path.samefile(f1, f2) 
== True for any files f1 and f2 on Google File Stream.

I propose the following patch, which currently works for me:

[issue33919] Expose _PyCoreConfig structure to Python

[Barry A. Warsaw]

Barry A. Warsaw  added the comment:

I think the basic implementation problem is that by the time you get to 
get_hash_info() in sysmodule.c, you no longer have access to the _PyCoreConfig 
object, nor the _PyMain object that it's generally attached to.

I write a C function to test _Py_DecodeUTF8Ex():

* surrogateescape=1 escapes the bytes as expected as: '\udced\udcb2\udc80'

Ok, I just misunderstood the code: the decoder is fine!

[issue33934] locale.getlocale() seems wrong when the locale is yet unset (python3 on linux)

[Nicolas Hainaux]

New submission from Nicolas Hainaux :

Expected behaviour:

When unset, the locale in use is `C` (as stated in python documentation) and 
`locale.getlocale()` returns  `(None, None)` on Linux with python2.7 or on 
Windows with python2.7 and python 3.6 (at least):


$ python2
Python 2.7.15 (default, May  1 2018, 20:16:04) 
[GCC 7.3.1 20180406] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import locale
>>> locale.getlocale()
(None, None)
>>> 


Issue:

But when using python3.4+ on Linux, instead of `(None, None)`, 
`locale.getlocale()` returns the same value as `locale.getdefaultlocale()`:


$ python
Python 3.6.3 (default, Oct 24 2017, 14:48:20) 
[GCC 7.2.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import locale
>>> locale.getlocale()
('fr_FR', 'UTF-8')
>>> locale.localeconv()
{'int_curr_symbol': '', 'currency_symbol': '', 'mon_decimal_point': '', 
'mon_thousands_sep': '', 'mon_grouping': [], 'positive_sign': '', 
'negative_sign': '', 'int_frac_digits': 127, 'frac_digits': 127, 
'p_cs_precedes': 127, 'p_sep_by_space': 127, 'n_cs_precedes': 127, 
'n_sep_by_space': 127, 'p_sign_posn': 127, 'n_sign_posn': 127, 'decimal_point': 
'.', 'thousands_sep': '', 'grouping': []}
>>> locale.str(2.5)
'2.5'


Though the locale actually in use is still `C` (as shown above by the output of 
`locale.localeconv()` and confirmed by the result of `locale.str(2.5)`, which 
shows a dot as decimal point and not a comma (as expected with `fr_FR.UTF-8`)).

I could observe this confusing behaviour on Linux with python3.4, 3.5, 3.6 and 
3.7 (rc1). (Also on FreeBSD with python3.6.1).

A problematic consequence of this behaviour is that it becomes impossible to 
detect whether the locale has already been set by the user, or not.

I could not find any other similar issue and hope this is not a duplicate.

I agree that error messages sometimes is misleading if use the C API.

PR 7846 fixes this, although I'm not sure this is the best wording.

they're happy with it, but I suspect since they weren't broken before they

[issue33933] Error message says dict has no len

[Vedran Čačić]

New submission from Vedran Čačić :

Look at this:

>>> import bisect
>>> bisect.bisect({}, None)
Traceback (most recent call last):
  File "", line 1, in 
bisect.bisect({}, None)
TypeError: object of type 'dict' has no len()

Of course, objects of type 'dict' do have len. The problem is that bisect 
considers its first argument a sequence, which is very sensible to do 
(although, with ordered dicts, it's not the only sensible choice), but it gives 
a very wrong error message given that context.

At https://bugs.python.org/issue32500, R. David Murray told me to open this.

[issue33932] Calling Py_Initialize() twice now triggers a fatal error (Python 3.7)

[STINNER Victor]

New submission from STINNER Victor :

It would help to document that calling Py_Initialize() twice in Python 3.7 now 
triggers a fatal error, whereas previous the second call did nothing. Document 
it at:
https://docs.python.org/dev/whatsnew/3.7.html#changes-in-the-c-api

... Or should it be considered as a regression?

--

My colleague Miro Hrončok reported a Python crash (SIGABRT) when running 
https://github.com/konlpy/konlpy test suite on Python 3.7:

"Fatal Python error: _Py_InitializeCore: main interpreter already initialized"

konlpy uses the JPype project, the bug is in JPype initialization function 
(it's a C extension):

[issue33903] Can't use lib2to3 with embeddable zip file

[Steve Dower]

Steve Dower  added the comment:

There's a command to generate that file though I forget what it is. The 
embeddable distro does not support installation, though it may work sometimes 
(it's still the same Python binaries).

Try going to nuget.org, search for Python and install one of those packages 
(there should be instructions on the site). Alternatively, I think the 
WinPython distro has a non-installed version that you may be able to use.

[issue33931] Building 2.7 on Windows with PC\VS9.0 is broken

[Anselm Kruis]

New submission from Anselm Kruis :

Currently 2.7 fails to build on Win32 using PC\VS90\build.bat -e for two 
reasons:

1. Wrong openssl version: PC\VS9.0 is still at version 1.0.2k, whereas 
PCbuild/get_externals.bat downloads version 1.0.2o.

2. Building tcl fails with well known "nmakehlp" not found problem. It is 
caused by the following line in PC\VS90\build.bat: "nmake -f makefile.vc 
MACHINE=%machine% DEBUG=%debug_flag% INSTALLDIR="%tcltkdir%" clean all". 
Separate invocations of nmake for "clean" and "all" fix the problem.

I'll provide a pull request for both issues. I hope it is OK to make just a 
single PR, because the changes are trivial.


Relevant output from PC\VS90\build.bat:

[issue33921] Explain that '' can be used to bind to all interfaces for the AF_INET address family in the docs

[John Hagen]

John Hagen  added the comment:

@ammar2

I see that now. Yeah it's further down in the docs and doesn't actually call 
out '' like is done for AF_CAN:

A tuple (interface, ) is used for the AF_CAN address family, where interface is 
a string representing a network interface name like 'can0'. The network 
interface name '' can be used to receive packets from all network interfaces of 
this family.

Ideally I think putting something in this section would be helpful:

A pair (host, port) is used for the AF_INET address family, where host is a 
string representing either a hostname in Internet domain notation like 
'daring.cwi.nl' or an IPv4 address like '100.50.200.5', and port is an integer.

[issue33928] _Py_DecodeUTF8Ex() creates surrogate pairs on Windows

[STINNER Victor]

STINNER Victor  added the comment:

Extract of _Py_DecodeUTF8Ex() code, there is an explicit "write a surrogate 
pair" comment:

#if SIZEOF_WCHAR_T == 4
ch = ucs4lib_utf8_decode(&s, e, (Py_UCS4 *)unicode, &outpos);
#else
ch = ucs2lib_utf8_decode(&s, e, (Py_UCS2 *)unicode, &outpos);
#endif
if (ch > 0xFF) {
#if SIZEOF_WCHAR_T == 4
Py_UNREACHABLE();
#else
assert(ch > 0x && ch <= MAX_UNICODE);
/* write a surrogate pair */
unicode[outpos++] = (wchar_t)Py_UNICODE_HIGH_SURROGATE(ch);
unicode[outpos++] = (wchar_t)Py_UNICODE_LOW_SURROGATE(ch);
#endif
}

[issue33921] Explain that '' can be used to bind to all interfaces for the AF_INET address family in the docs

[Ammar Askar]

Ammar Askar  added the comment:

It's kinda mentioned:

"For IPv4 addresses, two special forms are accepted instead of a host address: 
the empty string represents INADDR_ANY"

Though it could be more explicit on what means since binding to all interfaces 
is a common use case.

_Py_DecodeUTF8Ex() creates surrogate pairs with 16-bit wchar_t (on Windows), 
whereas input bytes should be escaped. I'm quite sure that it's a bug.

It would be nice to have same infile and outfile for json.tool to replace json

Currently, if I try this I get an error:

[issue33926] test_gdb is skipped in builds since gdb is not installed as part of build script

[Karthikeyan Singaravelan]

New submission from Karthikeyan Singaravelan :

I was checking on https://bugs.python.org/issue30345 and 
https://bugs.python.org/issue33914. I looked into Travis and VSTS builds for 
test_gdb. Though python is built with `--with-pydebug` gdb is not installed in 
the builds and hence the test_gdb is skipped. Adding installation of gdb will 
help in making sure test_gdb is run.

# test_gdb skipped : 

* https://travis-ci.org/python/cpython/jobs/394900803#L1532

# After installation of gdb 

My build fails due to urllib errors and trying to install gdb using sudo 
apt-get install gdb on MacOS. The config can be fixed.

test_gdb tests : https://travis-ci.org/tirkarthi/cpython/jobs/394947895#L2501

I am willing to make a PR for Travis but I don't know how VSTS config works to 
test it on VSTS builds with an account.

Thanks

[issue33925] builtin_function_or_method compares __self__ by identity instead of equality

[Jeroen Demeyer]

New submission from Jeroen Demeyer :

Methods of Python functions compare equal if the functions are equal and if 
__self__ is equal:

>>> class X:
... def __eq__(self, other): return True
... def meth(self): pass
>>> X().meth == X().meth
True

This is because X() == X() even though X() is not X().

For extension types, we get instead:

>>> [].append == [].append
False

This is because comparison is done with "is" instead of "==". This is a 
needless difference.

[issue23224] LZMADecompressor object is only initialized in __init__

[STINNER Victor]

STINNER Victor  added the comment:

Calling directly __new__() is very unusual, so I'm not surprised that you found 
bugs. Calling __init__() twice is also an unusal practice. I concur with 
Serhiy: implementing new instead of init should prevent such bug. I recall that 
some objects decided instead to raise an exception if they are not fully 
initialized (if init has not been called), but using new instead of init seems 
to be safer approach if we can implement it.

In the meanwhile, I blocked by the memory leak (handle leak) in bz2 and lzma: 
bpo-33916. I proposed a very simple fix: PR 7843. I propose to apply this one 
since it's easy to backport it to all branches, whereas replacing init with new 
would be more difficult and risky to backport: I would suggest to only make 
this change in the master.

What do you think?

[issue33910] update random.Random 's parameter to have a proper name.

[Matthias Bussonnier]

Matthias Bussonnier  added the comment:

Thanks @rhettinger, this is a perfectly valid position, and one of the respons 
I was expecting.

>  That said, it doesn't seem to have ever caused a problem in practice (this 
> API has been around for a very long time)

I have myself not found a lot of usage of `random.Random(x=123)` though I can't 
say what the lack of occurences is due to. If I have the choice between
  - Random(123)
  - Random(x=123)
  - Random(seed=123)

I definitively find `Random(x=123)` the  least readable. I can guess what 
`Random(123)` means, `Random(seed=123)` is self-explanatory, `Random(x=123)` 
will make me doubt what this means. So you might say no one as reported problem 
because no one is using it...

Yes `x` is explained in the docstring, but that's still requires reading the 
docstring and reaching for it. As some tab completion engine show functions 
signatures I want to argue that good parameter names could thus make a 
difference.

Thanks again for you quick response I'm going to close corresponding PRs.

[issue33903] Can't use lib2to3 with embeddable zip file

[Mickaël S .]

Mickaël S.  added the comment:

In my case, on the computer doing releases, I cannot use the full Python 
installer (even with a minimal unattend.xml file) because any software 
installation is prohibited. This is an issue in my side but it is for the 
context.

I was expecting to be able to install modules even with the embeddable Python. 
I do not see that limitation in the docs.

The issue here is that I cannot install a package with no wheel because pip 
requires 'lib2to3\\Grammar3.6.5.final.0.pickle' (even if I am targetting python 
3.6 only). Do you see it as an issue or a desired behavior?

A thanks!

In the meantime I found the corresponding changelog entry:

I checked the corresponding commit:

there is no documentation update. It would be nice if the new feature can be 
found in the documentation (including the fact that -64 is only supported after 
installing python 3.7 or newer)...
