[issue20779] Add pathlib.chown method

[Vajrasky Kok]

Vajrasky Kok added the comment:

Pragmatic reasons:

I use chown moderately often. Usually as root, I want to change the uid of the 
files after generating a bunch of files. But I almost never changed gid.

I am in two mind whether I should add lchown as well or not (just like lchmod) 
and make the signature of pathlib.chown same as os.chown (with third parameter, 
follow_symbolic_links).

If you close this as won't fix, I will not hold grudge against you, though. ;)

[Ned Deily]

Ned Deily added the comment:

The traceback shows an issue when using envoy, which is not part of the Python 
standard library.  Assuming you are using the envoy listed in PyPI, I suggest 
you ask on the project's issue tracker:

Sorry, you are going to have supply more information.  From the traceback 
supplied, it appears the call to subprocess is coming from envoy, which is not

[issue20035] Suppress 'os.environ was modified' warning on Tcl/Tk tests

[Terry J. Reedy]

Terry J. Reedy added the comment:

The patch works to suppress the message for test_ttk_guionly.  However, 
unfix_environ does not undo everything that needs to be undone, as evidenced by 
#20800.

The patch does not fix test_idle. I suspect that this is because test_idle 
pulls in tests from numerous modules, none of which has the unfix call. 
However, rather than require a tearDowmnodule for every module that imports 
tkinter, lets fix the root problem. I thought of having the environment change 
warning function ignore changes to TCL/TK/TIX_LIBRARY, but even better would be 
to not change them. Rename _fix to _dirs and redefine its mission as setting 
and holding three module attributes: tcldir, tkdir, and tixdir. They would be 
set from either the environment or the alternate search code. Any other modules 
that need the info should get it from _dirs rather the environment.

I believe this part of _fix is buggy.
+if "TCL_LIBRARY" not in os.environ:
+for name in os.listdir(prefix):
+if name.startswith("tcl"):
+tcldir = os.path.join(prefix,name)
+if os.path.isdir(tcldir):
+os.environ["TCL_LIBRARY"] = tcldir
Both base/tcl and base/../tcktk/lib contain (for 3.4) directories named tcl8 
and tcl8.6. Since only tcl8.6 works, the code above depends on listdir 
presenting it second. The 'if name' clause could be augmented with 'and 
name[-2] == '.'.

[issue20265] Bring Doc/using/windows up to date

[Zachary Ware]

Zachary Ware added the comment:

Windows 8 (or at least 8.1) doesn't seem to be too far off from the directions 
on that site.  If you're proficient enough to change an environment variable in 
Windows 7, chances are good you can figure it out on Windows 8(.1).  If you're 
not, chances are good you probably shouldn't :)

Either way, I think that these days giving instructions on how to set an 
environment variable is beyond the scope of the Python documentation.  We ought 
to just say "here's the environment variables that Python cares about, and 
here's what they do" and leave the instructions for setting them to other 
sites.  We might link to some site deemed to have good instructions, but 
keeping them inline means trying to keep them updated, which has apparently not 
gone well :)

[issue20739] PEP 463 (except expression) implementation

[Chris Angelico]

Chris Angelico added the comment:

I've applied all the changes my script can find, including ones that are 
actually quite inappropriate, like:

try:
some_function_call()
except some_exception:
some_other_function_call()

All tests pass except for one, which I don't fully understand. Attaching 
patches:

1) make_stuff_work.diff - what it says on the tin. I don't understand 
everything that's going on in there, but the build process made some changes to 
tracked files.

2) churn1.diff - mostly-plausible edits. They're unnecessary code churn, and 
shouldn't be done wholesale like this, but they make the obvious changes.

3) churn2.diff - less plausible edits, in the two-expression form shown above. 
These definitely shouldn't be done... but they don't break any of the tests, so 
they're a reasonable proof that the concept works.

4) broken.diff - for some reason that I don't understand, this causes a test 
failure. Something that's supposed to produce no output now produces a warning. 
I cannot figure out how there's a difference in there. Advice please?

The broken one is of the inappropriate type, but the fact that it doesn't work 
seems... indicative, somehow. Indicative of what, I don't know, and it's 8AM 
after I've been up all night, so I'm not going to try further to figure this 
out.

[issue20794] ImportError: Bad magic number in .pyc file

[Ned Deily]

Ned Deily added the comment:

As Peter notes, .pyc and .pyo files are in general not compatible across Python 
versions.  PEP 3147 was implemented in Python 3.2 to help avoid the problem you 
are seeing by storing .pyc/.pyo files with version-specific filenames.  For 
Python 2, you need to be careful to recompile (see "compileall") or delete 
.pyc/.pyo files when changing interpreter versions.

Thanks for the report.  There was a lengthy discussion of this behavior a few 
years ago in Issue3067.  At that time it was decided not to change this

considered then, however you can work around it by using the b"" literal syntax:

locale.setlocale(locale.LC_ALL, b'POSIX')

Okay, thanks.  I was reviewing and rather liked the less invasive patch, but
if this one is going to make it into 3.4.1, I'll review it and test it
locally.  We can patch Ubuntu's 3.4 for now.

[issue20798] Reversed order in testtools messages

[Pete Zaitcev]

New submission from Pete Zaitcev:

When using an assert such as self.assertEquals(tester(), expected), an error 
message suggests wrong argument order (as in, not the order in examples in the 
documentation). Apparently this is confusing enough that OpenStack even opened 
a whole bunch of bugs and filed patches to swap the order in the tests:
 https://bugs.launchpad.net/ceilometer/+bug/1277104

If the code is:

import testtools

class TestConfigTrueValue(testtools.TestCase):
def test_testEquals(self):
reference = "reference-0123456789012345678901234567890123456789"
def function_under_test():
return "actual-0123456789012345678901234567890123456789"
self.assertEquals(function_under_test(), reference)

then running it yields

[zaitcev@guren xxx]$ python3 -c 'import nose; nose.main()'
F

[issue20792] IDLE: Extend tests for PathBrowser

[Terry J. Reedy]

Terry J. Reedy added the comment:

We do not usually make pure style changes in a file unless the code is being 
reviewed and edited. Even then, I focus on changes that make the file easier to 
read and understand, as is necessary to write tests. One example is adding 
missing spaces after commas in function definitions and calls (not a problem in 
this file, as far as I see). Another is to add PEP8 style docstrings to 
document the behavior being tested. That is an issue for this file. The name 
clashes do not bother me: 'file' is no longer a builtin in 3.x; 'sorted' was 
used in the file before the builtin was added (though I might think of 
something different if I were writing today). So lets leave the names alone and 
focus on good docstrings.

[issue20739] PEP 463 (except expression) implementation

[Chris Angelico]

Chris Angelico added the comment:

One test failing, due to Tools/parser/unparse.py not knowing how to unparse an 
except expression. Otherwise, test suite passes (with most of the stdlib 
unchanged). I'm about to try writing an actual conversion script which will 
rewrite the stdlib, and then see how much of the test suite still passes. (For 
this, I'll be doing only the easiest/simplest translations - the ones that 
involve simple or augmented assignment, and return statements - and I'll ignore 
PEP 8.)

[issue20797] zipfile.extractall should accept bytes path as parameter

[Laurent Mazuel]

New submission from Laurent Mazuel:

Many methods which use path in Python now accept string or bytes in parameter 
(e.g. all methods in "os.path", the "open" method, etc.).

Actually, sometimes it is not possible to handle a file without using bytes 
path. For example, path coded in another encoding system than the current 
locale system (e.g. a Windows filename encoded in "cp1252" against a Linux 
"utf-8" system).

Since "zipfile.extractall" uses path, it should accept bytes as path. Currently 
it leads to an error:
  File "/usr/local/lib/python3.3/zipfile.py", line 1262, in _extract_member
targetpath = os.path.join(targetpath, arcname)
  File "/usr/local/lib/python3.3/posixpath.py", line 92, in join
"components.") from None
TypeError: Can't mix strings and bytes in path components.

This bug is closely related to bug 20329 but is not the same (but maybe this 
enhancement will create a good debate around bytes support in zipfile module 
:-) )

[issue20501] fileinput module will read whole file into memory when using fileinput.hook_encoded

[Zachary Ware]

Zachary Ware added the comment:

Agreed with Vajrasky, the 2.7 commit wasn't as clean as it could be (sorry I 
didn't get an actual review done before you committed, I posted my last test 
results in a bit of a hurry).  The commented out line should either be removed, 
or used instead of the 'with' block above it.  I would actually vote for using 
writeTmp, and make a new issue for making writeTmp use a context manager.

Also, I think the new test_readline could be made a little clearer by putting

+fi = FileInput(files=TESTFN, openhook=hook_encoded('ascii'), bufsize=8)
+self.assertEqual(fi.readline(), u'A\n')
+self.assertEqual(fi.readline(), u'B\r\n')
+self.assertEqual(fi.readline(), u'C\r')

inside a `try ... except UnicodeDecodeError: self.fail('Read to end of file')` 
block.

It goes looking for the .pyc cached file, does not find it, and fails. Test

[issue20794] ImportError: Bad magic number in .pyc file

[Peter Otten]

Peter Otten added the comment:

This is expected. You cannot run/import 2.6 .pyc files in python 2.7 because 
the file format has changed.

$ echo 'print "hello"' > tmp.py 
$ python2.6 -c 'import tmp'
hello
$ rm tmp.py
$ python2.7 -c 'import tmp'
Traceback (most recent call last):
  File "", line 1, in 
ImportError: Bad magic number in tmp.pyc

Naval, if you do have the source .py make sure that you delete all 
occurrences of .pyc in directories preceding the directory containing 
.py in sys.path. Sometimes this error is the result of moving a .py file 
into another directory and forgetting to delete the leftover .pyc.

[issue20793] locale.setlocale()

[René Fleschenberg]

New submission from René Fleschenberg:

locale.setlocale() does not work if you pass it a ``unicode`` object instead of 
a ``str`` (locale.py, line 576):

``if locale and type(locale) is not type(""):``

Maybe it would be better to do a check like this?

``if locale and not isinstance(locale, basestring):``

In particular, this can bite you if you use the ``unicode_literals`` future 
import, displaying a not-so-helpful error message ("ValueError: too many values 
to unpack" in _build_localename).

[issue20329] zipfile.extractall fails in Posix shell with utf-8 filename

[Laurent Mazuel]

Laurent Mazuel added the comment:

Thank for your answer.

Unfortunately, I cannot test easily python 3.4 for now. But I have downloaded 
the source code and "diff" from 3.3 to 3.4 the "zipfile" module and see no 
difference relating to this problem. I can be wrong, maybe if some core 
improvement of Python may change something?

[issue20792] IDLE: Extend tests for PathBrowser

[Steven D'Aprano]

Steven D'Aprano added the comment:

I think you may have misread PEP 8. It does not recommend a trailing underscore 
for names that shadow built-ins (e.g. file_ instead of file), it only 
recommends a trailing underscore when you need to use a keyword as a name (e.g. 
class_ instead of class). Shadowing built-ins should be done with care, but is 
permitted.

If there is little or no risk of confusion with the built-ins, there is no need 
to worry about shadowing them. It's just another name.

[issue20440] Use Py_REPLACE/Py_XREPLACE macros

[Kristján Valur Jónsson]

Kristján Valur Jónsson added the comment:

Well, Larry, I certainly am in no mood to start wrangling on python-dev.  A 25 
year old C standard is likely to be very mature and reliable by now.  Why take 
risks? :)

#Py_LOCAL_INLINE exists and demonstrates that we can make use of them when 
possible.
We could create a #Py_INLINE macro that would work the same, only not 
necessarily yield inline on some of the older compilers.

It would really be healthy for the pyton code base, for quality, for semantics, 
and for the learning curve, if we could start to rely less on macros in the 
core.

Ah well, perhaps I'll throw this out there...

[issue20440] Use Py_REPLACE/Py_XREPLACE macros

[Kristján Valur Jónsson]

Kristján Valur Jónsson added the comment:

Are you referring to the Py_LOCAL_INLINE macro?
I see that we have no Py_INLINE.  Py_LOCAL_INLINE includes the "static" 
qualifier, and in fact, if there is no "USE_INLINE" defined, then all that it 
does is to add "static".

Would having a "Py_INLINE(type)" macro, that is the same, but without the 
static (except when USE_INLINE is false) make a difference?  It would be a bit 
odd to have Py_LOCAL_INLINE() functions defined in the headers.

I'm not sure that there is any practical difference between "static inline" and 
"inline".  But there is a difference between "static" and "inline".

It would be great if we could start writing stuff like the Py_INCREF() and 
Py_DECREF() as functions rather than macros, but for this to happen we must be 
able to trust that they are really inlined.

Assuming that the current behaviour is by accident here's a patch that adds the

[issue20792] IDLE: Extend tests for PathBrowser

[Saimadhav Heblikar]

New submission from Saimadhav Heblikar:

This patch does 
1.Remove pep8 violations in PathBrowser.py . Replaces "file","dir","sorted" by 
"file_","dir_","sorted_" respectively.
2.Extends test coverage for PathBrowser.py in idle_test/test_PathBrowser.py

New modules now under tests include
1.dirBrowserTreeItem - getText,ispackagedir
2.pathBrowserTreeItem - getText,getSublist

Only method missing a test after this patch will be listmodules.I am not too 
sure whether it requires a test for itself.it is indirectly being tested from 
lines 8 and 9(in the current tip).

[issue20781] BZ2File doesn't decompress some .bz2 files correctly

[Nadeem Vawda]

Nadeem Vawda added the comment:

> How does one create a multi-stream bzip2 file in the first place?

If you didn't do so deliberately, I would guess that you used a parallel
compression tool like pbzip2 or lbzip2 to create your bz2 file. These tools work
by splitting the input into chunks, compressing each chunk as a separate stream,
and then concatenating these streams afterward.

Another possibility is that you just concatenated two existing bz2 files, e.g.:

$ cat first.bz2 second.bz2 >multi.bz2


> And how do I tell it's multi-stream.

I don't know of any pre-existing tools to do this, but you can write a script
for it yourself, by feeding the file's data through a BZ2Decompressor. When the
decompress() method raises EOFError, you're at the end of the first stream. If
the decompressor's unused_data attribute is non-empty, or there is data that has
not yet been read from the input file, then it is either (a) a multi-stream bz2
file or (b) a bz2 file with other metadata tacked on to the end.

To distinguish between cases (a) and (b), take unused_data + rest_of_input_file
and feed it into a new BZ2Decompressor. If don't get an IOError, then you've got
a multi-stream bz2 file.

(If you *do* get an IOError, then that's case (b) - someone's appended non-bz2
 data to the end of a bz2 file. For example, Gentoo and Sabayon Linux packages
 are bz2 files with package metadata appended, according to issue 19839.)

[issue20791] copy.copy(bytes) is slow

[Frank Millman]

New submission from Frank Millman:

Using copy.copy on a byte string returns a new copy instead of the original 
immutable object. Using copy.deepcopy returns the original, as expected. 
Testing with timeit, copy.copy is much slower than copy.deepcopy.

>>> import copy
>>>
>>> a = 'a'*1000  # string
>>> copy.copy(a) is a
True
>>> copy.deepcopy(a) is a
True
>>>
>>> b = b'b'*1000  # bytes
>>> copy.copy(b) is b
False
>>> copy.deepcopy(b) is b
True
