[Ross Lagerwall]

Do you think the Autoconf section (about regenerating configure) should stay 
where it is or be moved somewhere else?

[issue14527] How to link with an external libffi?

[Ross Lagerwall]

Ross Lagerwall rosslagerw...@gmail.com added the comment:

If it is in a non-standard location, try setting the environment variables:

LDFLAGS linker flags, e.g. -Llib dir if you have libraries in a 
nonstandard directory lib dir
CPPFLAGS(Objective) C/C++ preprocessor flags, e.g. -Iinclude dir if you 
have headers in a nonstandard directory include dir

[issue15798] subprocess.Popen() fails if 0, 1 or 2 descriptor is closed

[Ross Lagerwall]

Ross Lagerwall added the comment:

It's caused by the following check in _posixsubprocess.c:
if (close_fds  errpipe_write  3) {  /* precondition */
PyErr_SetString(PyExc_ValueError, errpipe_write must be = 3);
return NULL;
}

which was written by Gregory P. Smith in 2010 (adding to nosy list).

I'm not entirely sure why this check is here, presumably its due to the way 
close_fds=True is handled.

The close fds logic is also hardcoded to close fds from 3 upwards,.

Re: Call for Assistance

I really appreciate all the conversation about the license. Perhaps I made a 
mistake with requiring noncommercial in the license, I don’t know, but I’ll 
look at the links provided about free documentation and free software and see 
if I can understand the issues more and perhaps make a better decision.

Honestly, I have no expectation that this book will ever be anything more than 
a (hopefully) useful resource for others like myself, as described in the 
current introduction. I might have a remote hope that it would be something 
that would receive attention from a traditional publisher, but that remote hope 
is in the same category as a remote hope that a distant rich uncle will someday 
name me in his well. So, given the minuscule odds of that happening, I’ll 
probably remove the NC portion. I’ll just do a bit of research first with those 
links.

Thanks,
Chuck

Meta Python Chapter 3 Available

[Charles Ross]

Call for Assistance

[Charles Ross]

I’ve begun a new book called Meta Python that I’m looking for assistance with. 
The book is one I wish was out there, and so am writing. The book is targeted 
at experienced programmers who are novice Python users and want to move from 
that point to one where they have published to PyPI.

I’m specifically looking for three types of users to assist me:

- Expert Python developers who are willing to confirm and correct the technical 
details, since I’m getting to the material that I want to learn and therefore 
need to teach. So far that only really includes virtual environments, covered 
in chapter 2, but will soon include many other topics.
- Developers like me, who aren’t new to programming but are perhaps new to 
Python and certainly new to publishing to PyPI, and who can provide feedback on 
the clarity and usefulness of the content.
- Linux and Windows Python users who would be willing to assist in making the 
book a bit less Mac-centric.

The book is being hosted at https://github.com/chivalry/meta-python 
. The introduction and first two 
chapters have their initial drafts complete, but you’ll see a few “TODOs” in 
there. Any and all feedback is appreciated, and preferred through the GitHub 
Issues system, but feel free to email me if you prefer.

Thanks,
Chuck

I don’t yet know precisely how the “book” will be published. I might just leave 
it as a set of GitHub files or export the Markdown to other format to be hosted 
outside GitHub. I’m not worrying yet about publishing, only clarity and 
correctness of content.

How to get Read the Docs to generate py-modindex.html?

[Charles Ross]

Since I appear to be experiencing one of the few times that Stack Overflow 
hasn’t provided any quick answers to a problem 
(http://stackoverflow.com/questions/39197037/how-to-get-read-the-docs-to-generate-py-modindex-html
 
),
 I’ll try posting my question here and see if anyone has a suggestion.

I'm trying to get Read the Docs to generate the `py-modindex.html` file. 
Research into a related question lead me to the following setup:

- `setup.py` in the project directory has the following contents, which were 
the minimum needed to get `pytest` to work and haven't been changed since I got 
that part of my project working:

import setuptools

setuptools.setup(
name='polygons',
packages=setuptools.find_packages(),
)

- `docs/requirements.txt` contains a single line:

sphinx-autodoc-annotation

- The Read the Docs repository URL points to my repository 
(https://github.com/chivalry/polygons).
- The RtD setting for "Install your project inside a virtualenv using setup.py 
install" is checked.
- The RtD setting for "Requirements file" points to `docs/requirements.txt`.

The "Module Index" link gets included in `index.html` 
(http://polygons.readthedocs.io/en/latest/), but the `py-modindex.html` file is 
missing.

My understanding is that with the virtualenv setting above, RtD will use the 
`setup.py` file to install the project so that Sphinx can read the 
documentation found in the Python docstrings. I'm using function annotations 
and would like `sphyinx-autodoc-annotation` to make use of those when creating 
the built docs files. All of this works splendidly on my local machine when I 
run `make html` while in the `docs` folder. Now I'm trying to get it to work on 
Read the Docs.

Thanks,
Chuck

RE: how to control formatting of a namedtuple in a list

[Boylan, Ross]

Actually,
>> print(list(foo, bar))
Traceback (most recent call last):  

  File "", line 1, in

TypeError: list() takes at most 1 argument (2 given)   

Though 
>>> [foo, bar]
['ham, eggs, cheese', 'bacon, toast'] 
which admittedly would be confusing if the strings weren't quoted. But display, 
or formatted values, are not intended to allow reconstruction of the objects; 
that's what repr is for. 

The argument that the display of list is already low-level, and so everything 
inside the list should be displayed low-level, seems a bit of a stretch.

Overriding repr is serviceable for me, but it requires violating the intended 
semantics of repr, namely that the result could be converted back to the 
original object. I'm trying to get a display that has only some of the 
information in the object.  My understanding is that str is supposed to provide 
that.

At any rate, I agree there are reasons to use repr inside a list.

Another example:

  >>> foo = 'ham, eggs, cheese'
  >>> bar = 'bacon, toast'

if list used str instead of repr:

  >>> print(list(foo, bar))
  [ham, eegs, cheese, bacon, toast]

How many items are in that list?  (Hint: it isn't 5. ;)

RE: how to control formatting of a namedtuple in a list

[Boylan, Ross]

Thank you; I can confirm that overriding __repr__ makes the list display as I 
wanted.

The decision to use repr inside the list seems very odd, given the context, 
namely formatting something for display or looking for a simple string 
representation.  It seems more natural to me to use str or, if in a format, the 
default formatting all the way down.  Is there a good reason it's repr?

Yep! Inside a list, it's the repr that gets shown. So you should be
able to do this:

class Foo(namedtuple("Foo", "x")):
def __repr__(self):
  return "foolish({})".format(self.x)

This will also affect the other forms - if you don't define __str__,
it'll use __repr__. So this should be all you need.

how to control formatting of a namedtuple in a list

[Boylan, Ross]

Even after defining custom __str__ and __format__ methods they don't affect the 
display of objects when they are in a list.  Is there a way to change that, 
other than explicitly converting each list element to a string?

The last line of output below shows that when I format the list I get standard 
formatting of my objects instead of my custom format.

Code
#! /usr/bin/python3
from collections import namedtuple

class Foo(namedtuple("Foo", "x")):
__slots__ = ()

def __str__(self):
  return "foolish({})".format(self.x)

def __format__(self, spec):
  return self.__str__()

f=Foo(4)
print(f)
print(str(f))
print("{}".format(f))
print("{}".format([f]))  # a list with one f

Output
foolish(4)
foolish(4)
foolish(4)
[Foo(x=4)]

I'm running Python 3.4.

Thanks.

error in syntax description for comprehensions?

[Boylan, Ross]

https://docs.python.org/3/reference/expressions.html#displays-for-lists-sets-and-dictionaries
describes the syntax for comprehensions as
comprehension ::=  expression comp_for
comp_for  ::=  [ASYNC] "for" target_list "in" or_test [comp_iter]
comp_iter ::=  comp_for | comp_if
comp_if   ::=  "if" expression_nocond [comp_iter]

Is the comp_for missing an argument after "in"?
One has to follow the definition of or_test and its components, but I can't 
find anything that results to a single variable or expression.

Actually, I'm not sure what or_test would do there either with or  without an 
additional element following "in".

[issue26350] Windows: signal doc should state certains signals can't be registered

[Ross Rosen]

Ross Rosen added the comment:

I'm not sure if this is helpful, but I thought it might be useful for you to 
hear a non-expert user's perspective.  (In summary, I'm agreeing with the OP.)

I spent a lot of time getting some signal handling working on OSX. Then finally 
in my process got to porting to Windows. I spent a bunch more time scratching 
my head trying to figure out why it wasn't working. Even after reading the 
os.kill and signal docs and searching for "Windows" I still wasn't clear what 
was wrong.  

This thread was the answer. 

So my suggestion at the least would be to put warnings in the signal doc, and 
clarify the language in the os.kill.

Re: Meaning of abbreviated terms

[Ross Wilson]

The "plist" abbreviation goes back to at least 1958 as it was used in 
the Lisp implementation [0].  And it may even predate Lisp.  I'm very 
sure that what actually went into a plist has often changed over the 
years, but the name persists.


Lisp also used "association lists" [1] which were a key/value data 
structure, usually called an "alist" or "a-list".

"plist" is "property list". It's listed in the Python documentation.

Thanks for the answer. Missed it till now.

In IBM-speak it was parameter list.



But that's not where plists came from, was it? As I understand it, the
plist data format was invented by Apple, and they called it a property
list.

How old is Apple?
I was using plist for parameter list in OS/360 in 1965.

[issue34585] Don't use AC_RUN_IFELSE to determine float endian

[Ross Burton]

New submission from Ross Burton :

Currently configure.ac uses AC_RUN_IFELSE to determine the byte order of floats 
and doubles.  This hurts when cross-compiling because a default is set, 
resulting in Python silently falling back to sub-optimal codepaths.

A partial improvement would be to not set a fallback, to force the user to set 
the right byte order explicitly.

However this test can be done without running anything.  autoconf-archive has a 
macro that uses a carefully constructed double that encodes to an ASCII string 
in the binary, which is then examined using grep.  Evil genius.

Attached is a POC using this.  Currently the autoconf-archive macro only 
handles big and little endian not the ARM OABI mixed-endian format, so 
configure.ac assumes if the byte order is unknown then it's the crazy 
mixed-endian.

To be honest OABI is so old now, I don't believe anyone actually uses it 
anymore: everyone still on ARMv4 should have moved to EABI many years ago, and 
the mixed-endian support could be removed from Py3 in the future.

>From what I can tell:

configure.ac sets PYTHON_FOR_BUILD like this if cross-compiling:

PYTHON_FOR_BUILD='_PYTHON_PROJECT_BASE=$(abs_builddir)

Note how PYTHONPATH is set to the source and build paths for Lib/.

The intention appears to be that the sysconfig.py in the build is used.  In my 
case that directory is also full of shared libraries that Python happily loads, 
and then fails.

[issue36159] Modify Formatter Class to handle arbitrary objects

[Ross Biro]

New submission from Ross Biro :

The only point in the string.Formatter class that really depends on string 
output is line 245: return ''.join(result), auto_arg_index.  

I'm currently working on a problem that would be much easier if I could get 
access to the result list instead of having that join called.

I propose creating another overridable method in string.Formatter, say oformat 
that calls _vformat and is called by vformat. oformat would have the guts of 
vformat and just return the result list.  vformat would then consist of the 
call ot oformat and the join.  See Below.  The recursive call to _vformat would 
also need some slight modification.

The work would not be difficult and I'm willing to do it, provided there is 
sufficient interest.

def vformat(self, format_string, args, kwargs):
result = self.oformat(format_string, args, kwargs)
return ''.join(result)

def oformat(self, format_string, args, kwargs):
used_args = set()
result, _ = self._vformat(format_string, args, kwargs, used_args, 2)
self.check_unused_args(used_args, args, kwargs)
return result

That's exactly the glitch.  I'm cross-compiling to a more powerful IA process

that you can rely on the loader to not open target binaries when they're on the

[issue36159] Modify Formatter Class to handle arbitrary objects

[Ross Biro]

Ross Biro  added the comment:

I'm currently writing a language translator between two domain specific
computer languages.  Because some expressions occur repeatedly, but in
slightly different contexts, I make multiple passes.  The first pass
reduces everything it can and leaves place holder objects for things it
can't reduce.  Later passes replace the objects with their final expression
in the new language.  The final expression varies by context, so every time
it's reevaluated, it could change.  I would really like to handle things
like a + b as

"{a} + {b}".format(a=a, b=b)

This works great when a and b are strings.  But when they are place holder
objects, I wasn't able to find a good solution.  Although the Formatter
class came so close that I thought I would suggest the change.  What I
ended up doing was replacing objects with unique strings so that I could
use format and then using regular expressions on the output string to split
it into an array and replace the string identifiers with the original
objects.  The change I've suggested to the Formatter class would have
allowed me to skip the regular expressions.

Hi Madhavan,

I can only see the first page of the paper you linked, so this might not
help.

Try looking at the "windrose" third-party library for matplotlib at
https://github.com/python-windrose/windrose .  The matplotlib page of
third-party libraries is at
https://matplotlib.org/3.1.1/thirdpartypackages/index.html#windrose .

As someone who finds the current behavior surprising, and having lost 
significant time because of it, I have a couple of comments.

1) If the venv created a python3 (or 2, as appropriate) file, would the 
expected behavior with !#/usr/bin/env python3 be restored?  I think the 
previous analysis said that python3 doesn't match the venv because there is no 
python3 in the venv path.  So putting one there would fix it.  Of course, it 
would only help for newly created venvs.  The pythonN file would need to be in 
addition to the python file, not instead of it, so that invocations of python 
without a number continued to work as expected.

2) There appear to be two separate sections of the documentation which govern 
this case. 3.7.1.2 of Python Setup and Usage says "If the launcher is run with 
no explicit Python version specification, and a virtual environment (created 
with the standard library venv module or the external virtualenv tool) active, 
the launcher will run the virtual environment’s interpreter rather than the 
global one. "
If py myscript.py is invoked that seems to fit this case, but obviously that's 
not what's happening.  I realize one could interpret the python3 in the shebang 
as an "explicit version specification", but a) that's not on the command line, 
which seems the more natural reading and b) it's only a partial specification, 
since it doesn't say which python3 to use.

Then section 3.7.2 is about !# lines.  So if you invoke py without a version 
specifier, but the invoked file has a !#, does 3.7.1.2 or 3.2 apply?

[issue40028] Math module method to find prime factors for non-negative int n

[Ross Rhodes]

New submission from Ross Rhodes :

Hello,

Thoughts on a new function in the math module to find prime factors for 
non-negative integer, n? After a brief search, I haven't found previous 
enhancement tickets raised for this proposal, and I am not aware of any 
built-in method within either Python's math module or numpy, but happy to be 
corrected on that front.

If there's no objection and the method does not already exist, I'm happy to 
implement it and open for review.

Ross

[issue40028] Math module method to find prime factors for non-negative int n

[Ross Rhodes]

Ross Rhodes  added the comment:

Hi Tim,

Are there any open discussions or threads following the proposed “imath” 
module? I’m a relatively new entrant to the Python community, so if there’s any 
ongoing discussion on that front I’d be happy to read further.

I think as a first step it would be good to implement this logic for a limited 
range of non-negative n, imposing an upper limit (suggestions welcome) to make 
sure all provided input can be safely processed. We can then build from there 
to support larger n going forward if the demand is out there.

Ross Rhodes  added the comment:

Hi Serhiy,

Thanks for sharing your thread. I support this proposal, and would be happy to 
help where time permits if we can gather sufficient support.

I inadvertently posted my support twice on your thread with no obvious means of 
deleting the duplicate post, since the first one had a delay appearing. 
Regardless, how can we best move forward with this idea?

[Ross Rhodes]

Ross Rhodes  added the comment:

Hi Steven,

I agree, your set of proposed methods seem sensible to me. I'm happy to start 
with an implementation of at least some of those methods and open for review, 
taking this one step at a time for easier review and regular feedback.

> Another question: since factorization can take a long time, should it be a 
> generator that yields the factors as they are found?

Yes, I think a generator is a sensible shout. Happy to proceed with this 
suggestion.

[issue42352] A string representation of slice objects with colon syntax

[Ross Barnowski]

New submission from Ross Barnowski :

It would be nice if there were a way to get a string representation of a slice 
object in extended indexing syntax, e.g.

```
>>> myslice = slice(None, None, 2)
>>> print(myslice)
'::2'
```

One motivating use-case is in descriptive error messages, e.g.

```
TypeError(f"Can't slice {myobj}, try list({myobj})[{myslice}]")
```

In this case, it is much more natural for `myslice` to use the extended 
indexing syntax than the slice str/repr.

Perhaps this could be done via __str__, or if that is too big a change, maybe 
via __format__ e.g. `f"{myslice:asidx}"`

It's simple enough to write a conversion function, but this feels like a 
feature that would fit best upstream. I searched the issue tracker, PRs on 
GitHub, and the Python documentation and didn't see any related 
issues/PRs/articles.

[issue42173] Drop Solaris support

[Gordon Ross]

Gordon Ross  added the comment:

I can understand the frustrations around dealing with minority platforms, but 
please remember that the illumos project (www.illumos.org) is basically the 
inheritor of problems around "Build on Solaris" for 3rd party software like 
Python.  There are several OS distributions based on illumos that would be 
impacted by removing the ability to (easily) build Python. I'm confident we can 
find some people to help maintain build-bots etc. if that's what it takes.  If 
you're still looking for such help, let me know and I'll ask on 
develop...@list.illumos.org for volunteers.

Thanks!  -GWR

[issue42787] email.utils.getaddresses improper parsing of unicode realnames

[Ross Rhodes]

Ross Rhodes  added the comment:

Hi Konstantin,

Thanks for raising this issue. It appears the field provided in your example 
does not conform to RFC 2822 followed by this email library. Square brackets 
are treated as special characters in [section 
3.2.1](https://tools.ietf.org/html/rfc2822#section-3.2.1), which is handled in 
the 
[_parseaddr](https://github.com/python/cpython/blob/master/Lib/email/_parseaddr.py#L219)
 file.

The above combined with the fact that any [failed parsing returns an two-tuple 
of ('', 
'')](https://github.com/python/cpython/blob/master/Lib/email/utils.py#L212) I 
believe explains the behavior observed.

Release 0.3.4 of orderedstructs including a C++/Python SkipList

[Paul Ross]

I have released v0.3.4 of the orderedstructs package that contains a high
performance SkipList implemented in C++ with Python bindings. A SkipList
behaves as an always sorted list with, typically, O(log(n)) cost for
insertion, look-up and removal. This makes it ideal for such operations as
computing the rolling median of a large dataset.

The characteristics of this SkipList implementation include:

   - No capacity restrictions apart from available memory.
   - Works with any C++ type  that has meaningful comparison operators.
   - The C++ SkipList can be compiled as thread safe.
   - The Python SkipList is thread safe.
   - Python SkipLists can be long/float/bytes/object types, the latter can
   have user defined comparison functions.
   - With Python 3.8+ SkipLists can be combined with the
   multiprocessing.shared_memory
   
<https://docs.python.org/3/library/multiprocessing.shared_memory.html#module-multiprocessing.shared_memory>
   module for concurrent operation on large arrays. For example concurrent
   roling medians
   
<https://skiplist.readthedocs.io/en/latest/rolling_median.html#rolling-median-in-python-with-multiprocessing-shared-memory>
   which speed up near linearly with the number of cores.
   - The implementation is extensively performance tested in C++ and Python.

There are a some novel features to this implementation:

   - A SkipList is a probabilistic data structure but we have deterministic
   tests that work for any (sane) random number generator. See testing a
   probabalistic data structure
   
<http://skiplist.readthedocs.io/en/latest/test_notes.html#testing-a-probabilistic-structure>
   - This SkipList can dynamically generate visualisations of its current
   internal state. See visualising a skiplist
   
<http://skiplist.readthedocs.io/en/latest/visualisations.html#skiplist-visualisation-label>

Not sure this qualifies as "use in the wild", but the memoized naive
Fibonacci is very nice when written this way:

def fib(n, memo={0: 0, 1: 1}):
if n not in memo:
memo[n] = fib(n-1) + fib(n-2)
return memo[n]

justifying text...and also...correct use of classes...

[Ross La Haye]

Few questions.  I have a module combin which contains Combin and Prob
classes.  This is the Prob class:

class Prob:
def binprob(self,n,k,p):
fewerthan = sum([Combin().kcomb(n,i)*((p**i)*(1-p)**(n-i)) for i in
range(k)])
exact = Combin().kcomb(n,k)*((p**k)*(1-p)**(n-k))
notexact = 1 - exact
atleast = 1 - fewerthan
atmost = fewerthan + exact
morethan = 1 - atmost

T0 = (('Fewer Than:', fewerthan),
('At Least:',  atleast),
('Exactly:',   exact),
('Not Exactly:', notexact),
('At Most:',  atmost),
('More Than:',   morethan))

for t in T0:
print t[0].rjust(12),'\t',t[1]

Is the way I've used the Combin class considered correct/appropriate in
the binprob method?  If not, what is the standard usage?  

Also, I'm trying to get my results to print close to this(.i.e., I would
like the first column to be right justified and the second column to be
exactly as it is):

Fewer Than: 0.376953125
At Least:   0.623046875
 Exactly:   0.24609375
Not Exactly:0.75390625
 At Most:   0.623046875
  More Than:0.376953125

but it comes out like this:

Fewer Than: 0.376953125
   At Least:0.623046875
Exactly:0.24609375
Not Exactly:0.75390625
At Most:0.623046875
  More Than:0.376953125

I feel like I'm missing something obvious here and apologize in advance if I
am, but I just can't figure it out.  Any help would be appreciated.  BTW,
I'm not using a dictionary because I want the results to print exactly in
the order specified and that seemed the simplest way.  Also, I used
rjust(12) because len(Not Exactly:) = 12 etc.

emulating an and operator in regular expressions

[Ross La Haye]

How can an and operator be emulated in regular expressions in Python?
Specifically, I want to return a match on a string if and only if 2 or more
substrings all appear in the string.  For example, for a string s = 'Jones
John' and substrings sg0 = 'Jones' and sg1 = 'John', I want to return a
match, but for substrings sg0 = 'Jones' and sg2 = 'Frank' I do not want to
return a match.  Because the expression 'A and B' is logically equivalent to
'not (not A or not B)' I thought I could try something along those lines,
but can't crack it.

Socket connection between python and C

[Williamson, Ross X. (Guest)]

Dear All,

I'm trying to implement a server/client system where the server is written in 
python and the client has to be written in c/c++.  I can happily send simple 
text through the socket. Ideally I would like make say a struct (using python 
struct library) - and then read that in using C. Is there a better way to 
package data on the server in python to send down a socket to a C client? XML? 
Pickle?

Cheers,

Ross
