Python: package root, root-node, __init__.py in the package root
I have a package structured like so on the file system: PKG LIBS are stored here: /usr/lib/python3.2/ Pkg-name: foo-1.0.0 1. What is the root directory, or root-node or 'root' of my package? My understanding is that it's: /usr/lib/python3.2/foo-1.0.0/ on the file-system and this is referred to the root of the pkg. 2. Can, foo-1.0.0 contain __init__.py or do i have to do: foo-1.0.0/foo/__init__.py ? Take a look at what this guy is saying on his blog: http://blog.habnab.it/blog/2013/07/21/python-packages-and-you/ --- (bottom of the page) Your project root should contain a python package, not be a package itself. If you do this, your setup.py will be very confusing (or not work at all) and it will be very difficult to run your code. (top of the page) passacre/__init__.py passacre/__main__.py 3. Could someone elucidate, explain what it is he's talking about? - Don?t directly run modules inside packages What I mean specifically is doing python passacre/__main__.py, or python passacre/test/test_application.py, or anything else that starts with python passacre/. This will prevent python from knowing where the root of your package is, and so absolute imports and explicit relative imports will fail, or not import the code you think it should be importing. 4.

It also means you can import your module and call its main() directly. That's useful for testing, but occasionally for other purposes too.

I was about that suggest that actually, just be careful to escape things

body rather than as query parameters. Going through the web server via
HTTP is most definitely going to be even more expensive than with pipes,
but if performance is the least of your concern, then this is probably
the easiest way to include things between languages.
Yet another methods of mixing languages is to use iframes and to built
your frontend as HTML with that queries Web APIs with AJAX but this
relies on the client side to do the inclusion.
As your goal is to eventually port an existing site to Python, I would
highly recommend against using Django. Django, as a full-featured
framework, is quite opinionated on how to do things, especially in
regards to database design. While this is great for a new projects as it
enforces certain well-tested patterns, this can be a pain when you need
to use existing tables from the PHP application. Also, if your old
application database access is written in SQL (i.e. with PHP mysql or
mysqli driver), it might be less friction to port to SQLAlchemy Core
rather than jumping straight to a full-fledged ORM, eventually you can
slowly take the next step to port SQLA Core to SQLA ORM. Or you can mix
and match Core and ORM with SQLAlchemy (with some care); Django is much
less flexible about mixing plain SQL with ORM.

To save having more than one build I use this for all downloads. Although I'm starting to consider making a second 32/64 distributable. Are there many major drawbacks for distributing this i386/ppc binary for all versions of OSX up 10.9 and 10.10? For a standalone app, not really. The main difference is that, by using the older 10.5 ABI, a few functions in the os module are not available (if they were implemented first in OS X 10.6 or later) and/or they may work a little differently. AFAIK, the most impactful difference, by far, is the OpenSSL version difference you have run into. Up to now, I don't recall any compatibility problems with 10.5 ABI programs running on later versions of OS X or, for the most part, mixing extension modules compiled to later ABIs with a 10.5 Python, although there might be issues with mixing versions of C++ modules (Python and its standard library do not use C++ themselves). But, of course, there's no guarantee that something won't break in a future release of OS X. So far, so good. Yea, I'm a bit worried that apple will break it on a future release- I think I will start looking into making a second build. I wonder what are the chances they'll make a 64bit only OSX one day? That's great news! Thanks for this! I've always found building things on mac a huge pain and wasn't much looking forward to the prospect of trying to build a 32/ppc python build on a 64 bit 10.10 machine (would that even be possible?). It's possible: I do it. But I cheat a bit: I have 10.5 running in a virtual machine on a 10.10 host. In theory, it's possible to build natively on 10.10. The trick is getting a version of Xcode 3 installed on 10.10 since support for building ppc archs was removed in Xcode 4. I also cheat a bit there: I happen to still have copies of Xcode 3.1.4 and 3.2.6 installed on 10.10 because I made sure to preserve them through upgrades from 10.6 days. IIRC, directly installing the necessary components from 3.2.6 on newer systems would require some hacking. Then you have to be really vigilant that the build never strays from the old SDK and tools, which is not something we claim to support at the moment. The VM approach is quite safe and reliable. I never thought about a VM for this for some reason- I have a few as well for basic testing on older OSX versions. I remember having to re-enable ppc in later versions of Xcode (http://stackoverflow.com/q/5333490/659346) when I was building some extensions for the app. That was a bit of a pain.

Re: [Python-Dev] Dinamically set __call__ method
On 05/11/14 06:15, Roberto Martínez wrote:
The thing with this is tricky. I need the change in the instance,
not in the class, because I have multiple instances and all of
them must have different implementations of __call__.
Why not just use functions with closure if that's what you need?
def a(one):
two = 'three'
def mycall(self):
nonlocal two
print 'NEW'
return mycall
Python functions are objects.
The workaround of calling a different method inside __call__
is not valid for my case because I want to change the *signature*
of the function also -for introspection reasons.
This seems like they should be two totally separate classes. If the
signature is different, then it violates the substitution principle. If
it violates substitution, then there is no reason why they should be of
the same class.
This was my first approach, but it is not very informative to the user
and I prefer to have arguments with descriptive names. We have to change
__doc__ too, so this is not an ideal solution for me.
I tried to implement __getattribute__, but is not called either. :(
Or you can use an factory function:
def A(p):
def xcall(self):
return 'X'
def ycall(self):
return 'Y'
class _A(object):
__call__ = xcall if p == 'x' else ycall
return _A
A('x')()(), A('y')()()
('X', 'Y')
or plain and simply just use inheritance if you want to pass an
isinstance check:
class A(object):
def __call__(self):
print 'OLD'
class A1(A):
def __call__(self):
print 'NEW'
What exactly, are you trying to do?

I am using Python 2.7 and each of my 'Worker' has a never ending loop that runs
continuously.
The documentation has this example:
from multiprocessing import Process
def f(name):
print 'hello', name
if __name__ == '__main__':
p = Process(target=f, args=('bob',))
p.start()
p.join()
Suppose this is in a module called 'example.py'.
When 'example.py' is run as the main module, it executes:
p = Process(target=f, args=('bob',))
p.start()
The multiprocessing module will _import_ 'example.py' in a new process,
and because it's only imported (and not run as a main module), that
code won't be executed. The multiprocessing module will then call the
'f' function.
The way you've written your module, it'll spawn a new process even when
it's only imported, causing the spawned process to spawn another
process, which will, in turn, spawn another...

A Freudian slip of *EPIC PROPORTIONS*!
Some of the folks on this list have attempted to shame me for not accepting with open arms, this vile encoding we call Unicode, but i wonder, are they aware of the deepest held beliefs of our very own leader? The other day whilst perusing the idlelib i came across a small but *very* significant line of code. They say a picture is worth a thousand words, well folks, this one short line of code might cause *ANY* picture blush with envy! The line is as follows: uniphooey = str However, without some context, even the more astute readers might miss the connection, so allow me to offer the comment that precedes this line: # The parse functions have no idea what to do with # Unicode, so replace all Unicode characters with x. # This is safe so long as the only characters germane # to parsing the structure of Python are 7-bit ASCII. # It's *necessary* because Unicode strings don't have a # .translate() method that supports deletechars. We can obviously intuit that uni is short for unicode, and by attaching phooey to unicode the author is making a public statement that he believes unicode is phooey. But what does phooey actually mean? The Merriam Webster online dictionary defines phooey as: PHOOEY: used to express disbelief, disappointment, or a strong dislike for something. So now it is blatantly obvious that the author of PyParse does not care for unicode, and from my recollection, it was the great GvR himself that wrote most, if not all, of the code for IDLE and Tkinter. Now that this revelation has seen the light of day, i wonder just how far apart myself and the great one might actually be on this unicode business? On the other hand, if the author is not GvR, then he is most likely someone of great importance within the community. In any event, i believe it is high time that the author explain his intentions when using the word uniphooey, because using any word should not be a crime, but hiding in the shadows whilst a fellow member is being lynched, and not having the balls to stand up and speak of your deeply held beliefs *IS* the highest of all crimes! It is a betrayal of not only your peers, but also of yourself. -- https://mail.python.org/mailman/listinfo/python-list

So how many times do we have to ask you to tell us your EXPECTED output before
you start actually doing that?
'bytes' is a built-in function, but built-in function definitions can be
overwritten by redeclaring them. In this case, you're deleting the bytes
function by assigning some read data to `bytes`. Don't do that. Either use a
variable name other than 'bytes', or recover your bytes function.

Python 3.x (beazley): __context__ vs __cause__ attributes in exception handling
In 'Chained Exceptions' - Beazley pg:626
try:
pass
except ValueError as e:
raise SyntaxError('foo bar') from e
-
Here, if ValueError is raised and SyntaxError is then raised.. 'e' contains
__cause__ which points to the ValueError Traceback. He goes on to say:
---
A more subtle example of exception chaining involves exceptions raised
within another exception handler. For example:
def error(msg):
print(m) # Note: typo is intentional (m undefined)
try:
statements
except ValueError as e:
error(Couldn't parse configuration)
---
Here, 'error' generates an inadvertent exception. What i don't understand is
this bit:
--
For implicit chaining, the _ _context_ _ attribute of an exception instance
e contains a reference to previous exception.
-
Why is he saying that 'e' contains a reference in __context__ to the
exception generated by 'error' ?? Is that correct? Surely, the exception
generated by 'error' will refer to 'e'? WTH??
For Implicit errors, there is no 'e'! Additionally, how would you go about
using __context__ if the exception is generated implicitly? Book pages:

[issue22852] urllib.parse wrongly strips empty #fragment
Stian Soiland-Reyes added the comment: I tried to make a patch for this, but I found it quite hard as the urllib/parse.py is fairly low-level, e.g. it is constantly encoding/decoding bytes and strings within each URI component. Basically the code assumes there are tuples of strings, with support for both bytes and strings baked in later. As you see in https://github.com/stain/cpython/compare/issue-2285-urllib-empty-fragment?expand=1 the patch in parse.py is small - but the effect of that in test_urlparse.py is a bit bigger, as lots of test are testing for the result of urlsplit to have '' instead of None. It is uncertain how much real-life client code also check for '' directly. (if not p.fragment would of course still work - but if p.fragment == '' would not work anymore. I therefore suggest an alternative to my patch above - to add some boolean fields like has_fragment, thus the existing component fields can keep their backwards compatible '' and b'' values even when a component is actually missing, and yet allowing geturl() to reconstitute the URI according to the RFC. -- hgrepos: +279 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue22852 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue22861] [2.7] ssl._dnsname_match() and unicode
New submission from STINNER Victor: Hi, I just modified the Trollius project ( http://trollius.readthedocs.org/ ) to support Python 2.7 with the newly backported ssl module. I ran the test suite of the Trollius and some tests are failing because of the exact exception message. It looks like ssl._dnsname_match() calls repr() on a Unicode string: elif len(dnsnames) == 1: raise CertificateError(hostname %r doesn't match %r % (hostname, dnsnames[0])) Well, I don't know if using repr() on an unicode string is really a bug or not. By the way, Trollius currently pass the hostname as a bytes string, whereas match_hostname() uses Unicode. No error is raised. Is it safe to compare bytes and Unicode to validate a certificate? dnsname[0] comes from the commonName of the certificate subject.

[issue22862] os.walk fails on undecodable filenames
New submission from Florian Höch: If 'top' is an unicode directory name, os.listdir can still return non-unicode filenames if they can't be decoded. This case is not handled in the Python 2.x standard library version of os.walk and will cause join(top, name) to fail on such filenames with an UnicodeDecodeError. -- components: Library (Lib) messages: 231110 nosy: fhoech priority: normal severity: normal status: open title: os.walk fails on undecodable filenames type: behavior versions: Python 2.7 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue22862 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue22863] https://docs.python.org/ should make a true 2.7.8 version available
New submission from Marc-Andre Lemburg: The documentation shown for Python 2.7.8 currently includes 2.7.9 parts, e.g. for the ssl modules (https://docs.python.org/2.7/library/ssl.html). Since there were so many changes to the ssl module for 2.7.9 which are not available in 2.7.8, I think it would be good to be able to not only select 2.7.8 from the doc version drop-down, but to also really get that particular version of the documentation, and provide a separate 2.7.9 snapshop as well. I tried https://docs.python.org/2.7.8/library/ssl.html, but that doesn't seem to exist. PS: I'm not sure whether this is the right tracker to report this. Feel free to move it elsewhere. -- assignee: docs@python components: Documentation messages: 231113 nosy: docs@python, lemburg priority: normal severity: normal status: open title: https://docs.python.org/ should make a true 2.7.8 version available versions: Python 2.7 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue22863 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

STINNER Victor added the comment: Your problem has two solutions. 1) Upgrade to Python 3 which handles correctly your use case (thanks to the PEP 383, surrogateescape error handler) 2) Only process filenames as bytes, and encode/decode manually (so you can decide how to handle undecodable filenames) -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue22862 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue22687] horrible performance of textwrap.wrap() with a long word
Serhiy Storchaka added the comment:
This is old rule. \w{2,}-(?=\w{2,} -- single letter shouldn't be separated. But
there was a bug in such simple regex, it splits a word after non-word character
(in particular apostrophe or hyphen) if it followed by word characters and
hyphen. There were attempts to fix this bug in issue596434 and issue965425 but
they missed a cases when non-word character is occurred inside a word.
Originally I had assigned this issue only to 3.5 because I supposed that the
solution needs either new features in re or backward-incompatible changes to
word splitting algorithm. But found solution doesn't require 3.5-only features,
doesn't change interface, and fixes performance and behavior bugs. So I think
it should be applied to maintained releases too.
