It's mostly an opinion that arises from debugging other people's
problems after they've managed to import the wrong thing without
realising it (cf. the "don't use 'socket.py' as the name of your
script for learning about how TCP sockets work" problem). We're aware
that annoys power users, but they're far better equipped to handle the
problem than if we inverted the situation.

Cheers,
Nick.

It's worth noting that https://docs.python.org/3/c-api/stable.html is
the relevant reference in the main C API docs.

Technically, I'm not scared of fixing it per se, I'm just wary of
trying to fix it without first refactoring it and writing some more
tests :)

Finding the roundtuits for PEP 432 is an eternal struggle though - so
many things end up edging ahead of it on the personal priority list :(

Nick.

Hello Ethan,

In addition to Guido's suggestion, the Python Developer Guide's Section 
7.4.9 should be helpful. Here's a link to Section 7 on Restructured Text 
https://docs.python.org/devguide/documenting.html#restructuredtext-primer
You may also find the Sphinx project documentation helpful if you need 
additional details.

In restructured text (rst), the .. syntax starts a directive.  There are 
a number of built-in directives, and there is the ability to extend the 
syntax with domain specific directives.


That must be the case here (since there doesn't appear to be a built-in 
directive named index), so we'll need more information about the source 
of your rst file before we can answer anything about that particular add 
on directive.

[Python-Dev] PEP 484

[Mario Figueiredo]

Please don't clutter executable code. We need to read it without growing an
headache.

Much better is:

  def myfunction(arg1, arg2):
  """
  Normal docstring...
  @hint: (str, int) -> bool
  """
  return True

While I agree type hinting, for the purposes of static analysis, has no
place in __doc__, I think that we could live with that. Otherwise:

  def myfunction(arg1, arg2):
  """
  Normal docstring...
  """
  "@hint: (str, int) -> bool"

Because our setup.py is a nightmare of arbitrary code run in a linear
fashion with ad-hoc checks for things that are unlike how any other project
on the planet determines what is available on your system.  It may have
seemed "great" when it was created in 2001.  It really shows its age now.

It defeats build parallelism and dependency declaration.
It also prevents cross compilation.

Building an interpreter with a limited standard library on your build host
so that you can run said interpreter to have it drive the remainder of your
build is way more self hosting that we rightfully need to be for CPython.

No, but we're thinking of mirroring our open-source packages on

You may want to have a look at the Setup files we're using
in eGenix PyRun, which uses them to force static builds of the
various built-in extensions.

Look for these files:

PyRun/Runtime/Setup.PyRun-2.7
PyRun/Runtime/Setup.PyRun-3.4

in the source archives:

you can do this using Setup.local. This works for me building additional

[Cyd Haselton]

Related to my earlier question regarding building Python on Android
and an undefined reference to dlopen error...I have the following
question:  Is it possible to build and install Python without having
to build and install...or use...distutils?

Some background:
I can build the python interpreter on my device, and I can build a
bunch of modules.  The problem appears when make reaches the part
where setup.py is used to build and import modules...specifically when
setup.py attempts to import distutils.core.

Thanks,
Cyd

Re: [Python-Dev] Undefined dlopen When Building Module On Android

[Cyd Haselton]

I guess I'll keep waiting...given the zero responses I've gotten from
the android side. :-(.

In the meantime...in case anyone is interested... since I have the
working binary, I executed it and went through each command in
setup.py to see what throws the 'undefined reference to dlopen' error.
Turns out that the distutils module is the culprit...specifically
distutils.core.

Re: [Python-Dev] PEP 448 (almost finished!) — Question regarding test_ast

[Walter Dörwald]

Thanks for taking a look.  I looked at inspect and I can't see 
anything
that needs to change since it's the caller rather than the receiver

more options after this PEP.


You are probably right. And for calling via Signature.bind() your patch 
takes care of business.



Did you see anything in particular?


No, I was just using inspect.signature lately and reading the PEP 
reminded me of it.



Best,

Neil

My question first:
test_ast is mostly generated code, but I can't find where it is 
being
generated.  I am pretty sure I know how to fix most of the 
introduced

problems.  Who is generating test_ast??

Update:

So far, I've done the following:

Updated the patch to 3.5
Fixed the grammar to accept final commas in argument lists always, 
and to

work with the already implemented code.
Fixed the ast to accept what it needs to accept and reject according 
to

the

limitation laid down by Guido.
Fixed the parsing library.

Fixed these tests:
test_ast.py
test_extcall.py
test_grammar.py
test_syntax.py
test_unpack_ex.py

As far as I can tell, all I have left is to fix test_ast and 
possibly

write
some more tests (there are already some new tests and some of the 
old

negative tests expecting SyntaxError are now positive tests).


inspect.signature might need an update.

Servus,
 Walter
