I'm with Martin about tests. Only one assertion per special case is needed, no 
need to write exponential number of combinations.

[issue24567] random.choice IndexError due to double-rounding

[Raymond Hettinger]

Raymond Hettinger added the comment:

> In sample() the selected set can be initialized to {n}

I originally used the {n} approach but it was less clear and it lead to a 
re-selection rather than undoing the rounding.  That would change the output.

> I like Tim's suggestion about import-time patching.

Sorry, but there's a limit to how much I'm willing to garbage-up the code over 
this issue.

> In choice() I would write the condition as "i == n > 0" to 
> avoid indexing with negative index

I'll write that as "'i == n and n > 0" which reads better and runs faster in 
the common case (look at the disassembly of each).

Attaching a revised patch.

> here's another timing variation:
>
>i = int(random() * n)
>return seq[i - (i == n)]

This ran a little slower than the conditional approach.

Serhiy Storchaka added the comment:

> re-selection rather than undoing the rounding.  That would change the output.

In normal case j is never equal to n. In very rare cases on platforms with 
double rounding the unpatched code generates an IndexError, and changing this 
is the purpose of the patch. Re-selection is so good as undoing the rounding.

Please also note that double rounding causes an error not only when 
int(random() * n) == n. If random() returns 0.5 - 2**-54 and n = 2029*2, the 
result is different with double rounding and without it. This causes small bias 
even if IndexError is not raised.

[issue24567] random.choice IndexError due to double-rounding

[Mark Dickinson]

Mark Dickinson added the comment:

Serhiy: there's already a small bias inherent in using `int(random() * n)`, 
regardless of double rounding, since in general `random()` gives 2**53 equally 
likely (modulo deficiencies in the source generator) outcomes and `n` need not 
be a divisor of `2**53`.  I don't think the double rounding is going to make 
that bias noticeably worse.

See issue 23974, which was resolved as "wont fix".

Berker Peksag added the comment:

Thanks for the report, Julien.

The up-to-date version of the document can be found at 
https://docs.python.org/devguide/documenting.html

Also, Python 3.0.1 documentation is really old and I think the "The Python 
documentation should follow the Apple Publications Style Guide wherever 
possible." part is no longer true.

[issue24611] Compiling Python 2.7.10 Error on Unixware 7.1.4

[Ron Barak]

Ron Barak added the comment:

When I try to apply the patch manually, namely - editing Modules/posixmodule.c, 
and moving the #endif a few lines up, the make finishes correctly.

So, the patch does work: I'm probably not applying it correctly.

Could you point to my error in applying the patch?

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

I'm aware of issue 23974. But I want to say that double rounding causes not 
only bias from ideal distribution, but a difference between platforms. The 
result of sample() (with the same seed) can vary between platforms.

[Ron Barak]

Ron Barak added the comment:

@Serhiy,
Not only would posting text be clearer, but much easier.
Alas, the Unixware I use is on a VirtualBox, and VitualBox does not support 
Guest Extension on Unixware - which means that neither cut-and-paste nor 
sharing host filesystem are possible.

So, unless I get any ideas of how to get text off my Unixware on VirtualBox, 
screenshots are all I have.

[issue24617] os.makedirs()'s [mode] not correct

[John Jones]

New submission from John Jones:

os.makedirs() gives the optional variable mode to set the permissions on the 
directories it creates.

While it seems to work for all triplet octal values (777,755,etc) it doesn't 
seem to work on values with the sticky bit (1777,1755,etc)

I know that to set the value as octal, you need, for some reason, to prepend a 
'0' to the number, such that the final value is '01755' - but even if you do 
int('1755',8) the error is there. Below I make a directory and then chmod it to 
the right value:

os.makedirs('/Users/Carolin/Desktop/demo',01703)
drwx-x 2 Carolin  staff  68 12 Jul 18:53 demo

os.chmod('/Users/Carolin/Desktop/demo',01703)
drwxwt 2 Carolin  staff  68 12 Jul 18:53 demo

[issue24567] random.choice IndexError due to double-rounding

[Stefan Krah]

Stefan Krah added the comment:

The double rounding problem even occurs between different versions
of gcc. I think ultimately we should put our foot down and ship with
sse2 enabled (not possible for 2.7 though, unless an LTS-PEP emerges).

If distributions want to break that, it's their business. :)
The gcc manual is quite upfront about the issue and really
recommends sse2 for reproducible results.

That's good for x86 but that wouldn't solve the issue if it exists on other 
archs.
I trust Raymond to come up with an acceptable solution; though I think it would 
be good to add a comment linking to this issue, in any case.

[issue24618] Invalid read in PyCode_New

[Brad Larsen]

New submission from Brad Larsen:

`PyCode_New` can read invalid heap memory.


File Objects/codeobject.c:

PyCodeObject *
PyCode_New(int argcount, int kwonlyargcount,
   int nlocals, int stacksize, int flags,
   PyObject *code, PyObject *consts, PyObject *names,
   PyObject *varnames, PyObject *freevars, PyObject *cellvars,
   PyObject *filename, PyObject *name, int firstlineno,
   PyObject *lnotab)
{
PyCodeObject *co;
unsigned char *cell2arg = NULL;
Py_ssize_t i, n_cellvars;

// ...

n_cellvars = PyTuple_GET_SIZE(cellvars);

// ...

/* Create mapping between cells and arguments if needed. */
if (n_cellvars) {
Py_ssize_t total_args = argcount + kwonlyargcount +
((flags & CO_VARARGS) != 0) + ((flags & CO_VARKEYWORDS) != 0); 
// *** 1 ***

// ...

/* Find cells which are also arguments. */
for (i = 0; i < n_cellvars; i++) {
Py_ssize_t j;
PyObject *cell = PyTuple_GET_ITEM(cellvars, i); 
for (j = 0; j < total_args; j++) {
PyObject *arg = PyTuple_GET_ITEM(varnames, j); 
// *** 2 ***
if (!PyUnicode_Compare(cell, arg)) {   
// *** 3 ***
cell2arg[i] = j;
used_cell2arg = 1;
break;
}   
}   
}

// ...
}

// ...
}

1. `total_args` is determined from parameters that are user-controlled
   (see `r_object` in `Python/marshal.c`, in the `TYPE_CODE` case,
   lines 1265--1277).
2. the `varnames` tuple is indexed with a value in the range [0, total_args),
   which could be larger than the range of valid indexes for `varnames`.
3. `arg` is now a bogus PyObject value, and causes a segfault in
   `PyUnicode_Compare`.

[issue24617] os.makedirs()'s [mode] not correct

[eryksun]

eryksun added the comment:

This is not a bug, but perhaps the documentation could further clarify that the 
set of valid values for the mode parameter is platform dependent. The [POSIX 
specification][1] for mkdir() states that "[w]hen bits in mode other than the 
file permission bits are set, the meaning of these additional bits is 
implementation-defined". On Linux, mkdir honors the sticky bit (S_ISVTX). On OS 
X, on the other hand, the [man page][2] states that "the behavior of mkdir() is 
undefined when mode bits other than the low 9 bits are used. Use chmod(2) after 
mkdir() to explicitly set the other bits".

[issue24619] async/await parser issues

[Stefan Krah]

New submission from Stefan Krah:

If I understand the reference manual correctly, these should probably
be rejected by the compiler:

>>> async def f():
... def g(): pass

... 
>>> async def f():
... def async():
... pass
... 
>>> async def f(): async = 10
... 
>>> async def f():
... def await(): pass
... 
>>> 


And this should perhaps be accepted:

>>> async def f():
... return lambda await: await
  File "", line 2
return lambda await: await
  ^
SyntaxError: invalid syntax


This, too:

>>> async def f():
... async def g(): pass

[issue24567] random.choice IndexError due to double-rounding

[Tim Peters]

Tim Peters added the comment:

I have a question about this new snippet in choice():

+if i == n and n > 0:
+i = n - 1

What's the purpose of the "and n > 0" clause?  Without it, if i == n == 0 then 
i will be set to -1, which is just as good as 0 for the purpose of raising 
IndexError (seq[any_int] raises IndexError when seq is empty).

[issue24567] random.choice IndexError due to double-rounding

[Tim Peters]

Tim Peters added the comment:

Hmm.  Looks like the answer to my question came before, via "Custom collection 
can has non-standard behavior with negative indices."  Really?  We're worried 
about a custom collection that assigns some crazy-ass meaning to a negative 
index applied to an empty sequence?  Like what?  I don't really care about 
supporting insane sequences ;-)

But I can reproduce the crash with other example.

import random
random.setstate((3, (1,)*624+(-10**9,), None))
random.random()

The index attribute can be set to negative value and this causes reading out of 
the buffer.

Here is a patch that fixes this.

[issue24567] random.choice IndexError due to double-rounding

[Tim Peters]

Tim Peters added the comment:

[Serhiy Storchaka]
> ... I want to say that double rounding causes not
> only bias from ideal distribution, but a difference
> between platforms

That's so, but not too surprising.  On those platforms users will see 
differences between "primitive" floating addition and multiplication (etc) 
operations too.

There's a tradeoff here.  In Python's earliest days, the bias was strongly in 
favor of letting platform C quirks shine through.  Partly to make Python-C 
interoperability easiest, but at least as much because hiding cross-platform fp 
quirks is a major effort and even Guido had only finite time ;-)  As the years 
go by, the bias has been switching in favor of hiding platform quirks.  I hope 
Python 3 continues in that vein, but Python 2 probably needs to stay pretty 
much where it is.

[issue24624] Itertools documentation says iterator when iterable is intended

[Neil Girdhar]

New submission from Neil Girdhar:

In the description of the consume recipe:

def consume(iterator, n):
"Advance the iterator n-steps ahead. If n is none, consume entirely."
# Use functions that consume iterators at C speed.
if n is None:
# feed the entire iterator into a zero-length deque
collections.deque(iterator, maxlen=0)
else:
# advance to the empty slice starting at position n
next(islice(iterator, n, n), None)

iterator should be replaced with iterable.  This function accepts strings for 
example, which are not iterators.

[issue24553] improve test coverage for subinterpreters

[Nick Coghlan]

Nick Coghlan added the comment:

As a possible starting point for this, I'll point to 
https://hg.python.org/cpython/file/02b81a82a57d/Lib/test/__main__.py

Now, I'd expected running that in a process that was *already* running regrtest 
to fail miserably (it would stomp all over itself).

But what we could potentially do is launch a *clean* subprocess, where the only 
thing it did was:

from _testcapi import run_in_subinterp

regrtest_in_subinterpreter = (
"""
from test import regrtest
regrtest.main_in_temp_cwd()
"""
)
run_in_subinterp(regrtest_in_subinterpreter)

I'd currently expect that to fail as well, but I think the failures might be 
enlightening :)

I'm also not sure we need to integrate this directly into the main regrtest 
test runner - it could just be a separate submodule invoked like "python -m 
test.subinterpretertest".

If we later decided to integrate it, then it could go behind a 
"-usubinterpreter" resource that invoked "test.subinterpretertest" in a 
subprocess.

It *accepts* strings, but it doesn't consume them. It runs through the 
string, but the string still exists and you can iterate over it again 
and again and again.

The intent of the recipe is to consume an *iterator* not arbitrary 
iterables. I don't believe the recipe or its description needs to be 
changed.

[issue24625] py.exe executes #! in windows

[진모씨]

New submission from 진모씨:

Well. A program linked to .py extension in windows (called py.exe) parses 
hashbang line(#!) and tries to execute program.

So hashbang like this:
#!/bin/env python
doesn't works, and
#!calc
executes calculator. I guess it is bug.

[issue24625] py.exe executes #! in windows

[eryksun]

eryksun added the comment:

To support cross-platform shebangs, the launcher special-cases the following 
virtual commands [1]:

/usr/bin/env python
/usr/bin/python
/usr/local/bin/python
python

The "env" virtual command searches the PATH environment variable. Note that 
it's /usr/bin/env since that's the most common location for the env utility on 
POSIX systems. If /bin/env is used there should at least be a symlink to it in 
/usr/bin.
