[issue18106] There are unused variables in Lib/test/test_collections.py

[Vajrasky Kok]

New submission from Vajrasky Kok:

In two "test_copying" methods in Lib/test/test_collections.py, variable i is 
never used. My guess is the original test writer forgot to utilize the variable 
i.

For example, in test_copying method in TestOrderedDict class:

def test_copying(self):
# Check that ordered dicts are copyable, deepcopyable, picklable,
# and have a repr/eval round-trip
pairs = [('c', 1), ('b', 2), ('a', 3), ('d', 4), ('e', 5), ('f', 6)]
od = OrderedDict(pairs)
update_test = OrderedDict()
update_test.update(od)
for i, dup in enumerate([
od.copy(),
copy.copy(od),
copy.deepcopy(od),
pickle.loads(pickle.dumps(od, 0)),
pickle.loads(pickle.dumps(od, 1)),
pickle.loads(pickle.dumps(od, 2)),
pickle.loads(pickle.dumps(od, 3)),
pickle.loads(pickle.dumps(od, -1)),
eval(repr(od)),
update_test,
OrderedDict(od),
]):
self.assertTrue(dup is not od)
self.assertEqual(dup, od)
self.assertEqual(list(dup.items()), list(od.items()))
self.assertEqual(len(dup), len(od))
self.assertEqual(type(dup), type(od))

The variable i in "for i, dup in enumerate" is never used.

The test_copying method in TestCounter class has the same problem.

In my opinion, we need to put variable i inside the message in the assert 
functions to detect which place inside the iteration the test fails.

[issue18106] There are unused variables in Lib/test/test_collections.py

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

Perhaps it will be even better to extract loop body as a local function and 
then call it with different arguments.

def check(dup):
self.assertTrue(dup is not od)
self.assertEqual(dup, od)
...
check(od.copy())
check(copy.copy(od))
...

In this case we will see a tested case right in the traceback.

[issue10224] Build 3.x documentation using python3.x

[Cherniavsky Beni]

Cherniavsky Beni added the comment:

I was only thinking of 3.4, which will have venv and a pip bootstrapper.
Is changing the doc build / doctest in scope for minor releases of 3.3 (or even 
earlier)?

The commands I listed (using setup_distribute.py) also work with 3.3.
(But they're unsecure -- https://bitbucket.org/tarek/distribute/issue/374/)
3.2 is harder as it doesn't even have builtin venv.

[issue18107] 'str(long)' can be made faster

[Armin Rigo]

New submission from Armin Rigo:

If you have in x some very large number, like 3**20, then the computation 
for 'str(x)' is sub-efficient.  Nathan Hurst posted to the pypy-dev mailing 
list a pure Python algo that gives the same result in 2/3rd of the time (in 
either CPython or PyPy).  We would get a similar gain by recoding this 
algorithm in C.

The mail is here: http://mail.python.org/pipermail/pypy-dev/2013-May/011433.html

[issue18106] There are unused variables in Lib/test/test_collections.py

[Vajrasky Kok]

Vajrasky Kok added the comment:

According to R. David Murray in Python core-mentorship mailing list addressing 
me:

"It could be that the bug is that the i is not used...it may have been
intended to be used in an extended error message in the asserts, so that
it would be clear which input failed.  In any case, I think the best
fix here would probably be to use the new subtests support in unittest."

So I used subTest feature in the second patch I upload according to his advice.

What do you think? subTest can recognize where the test fails immediately as 
well. You just have to count the line in the loop.

I would like to focus your attention, that flag "n" creates a database, but 
does not overwrite it once it is created. So in Windows case there is no 
difference between "c" and "n" flag.
You can have a look at this link where it was originally discussed.

[issue18108] shutil.chown should support dir_fd and follow_symlinks keyword arguments

[Colin Watson]

New submission from Colin Watson:

Python 3.3 added the dir_fd and follow_symlinks keyword arguments to os.chown; 
it also added the shutil.chown function.  Unfortunately the latter, while 
useful, does not support these new keyword arguments.  It would be helpful if 
it did.

[issue18093] Move main functions to a separate Programs directory

[Zachary Ware]

Zachary Ware added the comment:

I can confirm that the patch doesn't break building on Windows.

Would it make any sense to move Windows-specific sources for things like 
kill_python.exe (PCbuild/kill_python.c), make_buildinfo.exe, 
make_versioninfo.exe, py.exe (PC/launcher.c) into Programs?  Or better to keep 
them in PC or PCbuild (at least for now, until after this patch is approved)?

[issue17005] Add a topological sort algorithm

[Alexander Belopolsky]

Alexander Belopolsky added the comment:

+1

I had "tsort" in my own utilities library for so long that I thought it was in 
stdlib already.  I found this issue after unsuccessfully searching 
docs.python.org. :-)

I think functools will be a fine place for it.  It is somewhat related to total 
ordering and solves the problem which is common when implementing functional 
mini-languages.

Another possibility is shutil given that tsort is a standard POSIX command, 
, but I 
think this will be too obscure.

[issue18110] Nested set comprehensions in class scope fail

[Eric Wieser]

New submission from Eric Wieser:

This code:

class Sudoku(dict):
COLUMNS = [
{(x, y) for y in xrange(9)} for x in xrange(9)
]

When run on Python 2.7.5, fails with this traceback:

Traceback (most recent call last):
  File "", line 1, in 
class Sudoku(object):
  File "", line 3, in Sudoku
{(x, y) for y in xrange(9)} for x in xrange(9)
  File "", line 3, in 
{(x, y) for y in xrange(9)} for x in xrange(9)
NameError: global name 'x' is not defined

Yet `x` is clearly not a global - it's defined in the comprehension.

Running the comprehension outside of the class gives no error:

>>> [
{(x, y) for y in xrange(9)} for x in xrange(9)
]
[set([...]), ...]

Nor does using `set`:

class Sudoku(dict):
COLUMNS = [
set((x, y) for y in xrange(9)) for x in xrange(9)
]

[issue18090] dict_contains first argument declared register, and shouldn't be

[Terry J. Reedy]

Terry J. Reedy added the comment:

Guido, do you still believe in using 'register' in C code in general or in 
particular, for function arguments. Many of the uses in dictobject.c go back to 
your rev1256 and rev5396. The one that caught Larry's eye for dict_contains 
appears to be from the latter.

(Many other appearances are credited to Antoine as solipsis, though these may 
be from merges or something, and he has already said he thinks they could go.)

[issue18109] os.uname() crashes if hostname contains non-ascii characters

[STINNER Victor]

STINNER Victor added the comment:

"""
http://tools.ietf.org/html/rfc1178
  Don't use non-alphanumeric characters in a name.
"""

This is a recommendation, it does not mean that it is forbidden. But on Fedora, 
I'm unable to set a non-ASCII hostname. Arch Linux may be different.

Python should not fail with non-ASCII hostname, but I don't know which encoding 
should be used: ascii/surrogateescape (PEP 383)? the locale encoding + 
surrogateescape error handler?

[issue18111] Add a default argument to min & max

[Julian Berman]

New submission from Julian Berman:

This has come up a number of times I'm aware, but no one has ever written a 
patch for it as far as a quick look uncovered.

So here's one (written by Thomas Wouters but with permission to submit). 
Submitting without tests and docs, but those are incoming when I get a moment.

The justification here is mostly related to being able to call min/max on an 
iterable of unknown length when there's a sensible default (which is usually 
going to be None, but that's not the default for backwards compat obviously).

[issue13483] Use VirtualAlloc to allocate memory arenas

[STINNER Victor]

STINNER Victor added the comment:

I tested VirtualAlloc/VirtualFree versus malloc/free on Windows 7 SP1 64-bit. 
On my small test, when using VirtualAlloc/VirtualFree, the memory peak is lower 
(ex: 58.1 MB vs 59.0), and the memory usage is the same or sometimes lower. The 
difference is small, malloc() implementation on Windows 7 is efficient! But I 
am in favor of using VirtualAlloc/VirtualFree because it is the native API and 
the gain may be bigger on a real application.

--

I used the following script for my test:
https://bitbucket.org/haypo/misc/raw/98eb42a3ed2144141d62c75e3d07933839fe2a0c/python/python_memleak.py

I reused get_process_mem_info() code from psutil to get current and peak memory 
usage (I failed to install psutil, I don't understand why).

I also replace func() of my script with tuples.py to create many tuples.

--

Python < 3.3 wastes a lot of memory with python_memleak.py. Python 3.3 behaves 
much better thanks to the usage of mmap() on Linux, and the fixed threshold on 
64-bit (min=512 bytes, instead of 256).

[issue18109] os.uname() crashes if hostname contains non-ascii characters

[Dominik Richter]

Dominik Richter added the comment:

@haypo: You're right, RFC1178 is only a recommendation. RFC952 however is 
mandatory, although it doesn't seem to define  explicitly (or at 
least i wasn't able to find it; thus referencing POSIX).

Regarding Arch Linux's hostname: It is part of the package inetutils v1.9.1-5 
[1], which is GNU inetutils packaged [2]. Unfortunately I don't know which 
encoding it uses. I agree with you: It would be great if python supported it.

fyi: I opened a bug on Arch Linux [3] (thank you Dmi for the suggestion)

[issue3329] API for setting the memory allocator used by Python

[STINNER Victor]

STINNER Victor added the comment:

> typedef void *(*PyCCP_Malloc_t)(size_t size, void *arg, const char *file, int 
> line, const char *msg);

I don't understand the purpose of the filename and line number. Python does not 
have such information. Is it just to have the API expected by Unreal engine?

What is the message? How is it filled?

--

I'm proposing a simpler prototype:

void* (*malloc) (size_t);

Just because Python does not use or have less or more. I'm not against adding 
an arbitrary void* argument, it should not hurt, and may be required by some 
other applications or libraries.

@kristjan.jonsson: Can you adapt your tool to fit the following API?

PyAPI_FUNC(int) Py_SetAllocators(
char api,
void* (*malloc) (size_t size, void *data),
void* (*realloc) (void* ptr, size_t size, void *data),
void (*free) (void* ptr, void *data)
);

--

My pytracemalloc project hooks allocation functions and then use C Python 
functions to get the current filename and line number. No need to modify the C 
code to pass __FILE__ and __LINE__.

It can produce such summary:

2013-02-28 23:40:18: Top 5 allocations per file
#1: .../Lib/test/regrtest.py: 3998 KB
#2: .../Lib/unittest/case.py: 2343 KB
#3: .../ctypes/test/__init__.py: 513 KB
#4: .../Lib/encodings/__init__.py: 525 KB
#5: .../Lib/compiler/transformer.py: 438 KB
other: 32119 KB
Total allocated size: 39939 KB

You can also configure it to display also the line number.

[issue18104] Idle: make human-mediated GUI tests usable

[Terry J. Reedy]

Terry J. Reedy added the comment:

What I want is for the tests to be discovered when they should be and not when 
they should not ;-) -- without jumping through too many hoops. I probably once 
read 'recursing into subdirectories' but forgot. I like 'h_test...' for 'human 
test ...'.

Thinking about it more, unittest does not not add much to this type of test. If 
dialogs maps dialog to test information used by h_test_dialog, then a first 
draft of testing all (there are 6 that I know of, 3 with display tests) could 
amount to
def h_test_dialogs():
  for dialog in dialogs:
h_test_dialog(dialog)
New entries to dialogs would be 'discovered' as added.

[issue18114] Update PyImport_ImportFrozenModuleObject() to use importlib

[Brett Cannon]

New submission from Brett Cannon:

_imp.init_frozen is not really necessary; you can implement imports entirely 
using the other frozen-related functions. Because of that it's probably better 
to simply rewrite PyImport_ImportFrozenModuleObject() to use importlib to make 
the code easier to maintain and help guarantee consistency with other code.

[issue18115] Use importlib.util.module_to_load in all loaders in importlib

[Brett Cannon]

New submission from Brett Cannon:

BuiltinImporter, FrozenImporter, and ExtensionFileLoader all have their own 
custom code to manage clearing sys.modules if something goes wrong. Should see 
if any of them would break if they used importlib.util.module_to_load. And if 
they would break thanks to any pre-existing module in sys.modules, then add a 
keyword argument to suppress creating a new module.

[Brett Cannon]

Brett Cannon added the comment:

Turns out BuiltinImporter doesn't like having a pre-existing module, so a new 
keyword argument will be necessary to allow for only the cleanup code to run 
and not the construction of a new module.

[issue18104] Idle: make human-mediated GUI tests usable

[Terry J. Reedy]

Terry J. Reedy added the comment:

While improving the self-test for confixSectionNameDialog.py after fixing the 
error that stopped it from running, I discovered an error in the NameOk method: 
names were not really stripped before being tested. so duplicate section names 
were erroneously accepted if initially surrounded by whitespace. After fixing 
that, I removed unneeded code, including 5 pairs of parentheses in one 
statement, and added recommended spaces. I also centered the action buttons in 
the dialog.

Attached is a drop-in replacement for the file (produced with Idle on my 
non-developement  Win7 machine, so probably with the extra line end char). I 
think it is good enough to commit, but I am curious if the instructions added 
to the test are clear enough. (The dialog is the one seen if Save as New Custom 
Theme (Highlighting tab) or Save as New Custom Key Set (Key tab) are selected 
on the Options / Preferences dialog.

For new custom test files, the root window should be open farther from the edge 
of the screen.
