Teleport 0.3.0 released (Lightweight JSON Types)
I'm excited to announce Teleport 0.3.0, just 5 weeks after my 0.2.1 announcement. This release is based on a brand new language-agnostic specification [0], which I submitted as an Internet Draft. This specification, though backwards-incompatible with the last one, is a big improvement in simplicity. A new specification calls for a new implementation and new docs [1]. I am also happy to say that the mailing list [2] is no longer empty. Come join the discussion! = What is Teleport? = Teleport is a type system that extends JSON. You can use it for: * Validating input * Building JSON serializers * Building API servers and clients * Auto-generating API documentation * Exploring type systems Teleport's principles: * Minimalism ( 1000 LOC) * Portability and extensibility * Language-agnostic specification * To enforce existing conventions * Open Source (MIT license) [0] https://datatracker.ietf.org/doc/draft-boronine-teleport/ [1] http://teleport-json.org/python/latest/ [2] https://groups.google.com/forum/#!forum/teleport-json -- https://mail.python.org/mailman/listinfo/python-announce-list Support the Python Software Foundation: http://www.python.org/psf/donations/

ANNOUNCE: wxPython 3.0.2.0
Announcing -- wxPython 3.0.2.0 (classic) has been released and is now available for download at http://wxpython.org/download.php. This build includes fixes for some annoying bugs, including fixing ht Carbon buyild to actually use Carbon, and also adds the ability to be built for the GTK3 port. Various binaries are available for 32-bit and 64-bit Windows, and also for OSX using the Carbon and Cocoa APIs, for Python 2.6 and 2.7. Source code is also available at http://wxpython.org/download.php of course, for building your own. What is wxPython? - wxPython is a GUI toolkit for the Python programming language. It allows Python programmers to create programs with a robust, highly functional graphical user interface, simply and easily. It is implemented as a set of Python extension modules that wrap the GUI components of the popular wxWidgets cross platform library, which is written in C++. wxPython is a cross-platform toolkit. This means that the same program will usually run on multiple platforms without modifications. Currently supported platforms are 32-bit and 64-bit Microsoft Windows, most Linux or other Unix-like systems using GTK2 or GTK3, and Mac OS X 10.6+. In most cases the native widgets are used on each platform to provide a 100% native look and feel for the application, with some generic widgets filling the gaps where needed. -- Robin Dunn Software Craftsman http://wxPython.org -- https://mail.python.org/mailman/listinfo/python-announce-list Support the Python Software Foundation: http://www.python.org/psf/donations/

Instances (objects) have no way of knowing the name of the variable you attach them to. Or even if there is such a variable -- there could be one, or none, or a thousand. Consider: # one variable, one instance dealer = Hand() # three variables, one instance player1 = player2 = player3 = Hand() # make that four variables player4 = player2 # no variable, one instance print Hand() some_list = [1, 2, 3, Hand(), 5] If you ask each instance what their name is, how would they know? The only way is to give them a name when you create them: class Hand: def __init__(self, name): self.name = name dealer = Hand(dealer) player1 = Hand(Bert) player2 = Hand(Ernie) player3 = Hand(Scarface) Now the instances know what their name is, since you've told them, and can use them any way you like: def __str__(self): template = %s's hand contains: return (template % self.name) + King of Spades -- Steven -- https://mail.python.org/mailman/listinfo/python-list

You've already got self in the __str__ method, or you wouldn't have access to self.hand. But there's no characteristic of 'self' that has any idea of a name like dealer or player. You have to add that if you want it, as I suggested in my first guess. Steven has shown you as well, along with a better explanation. An object does NOT know the name or names that may be bound to it, any more than I know what page of the county register has my birth certificate recorded. If I want to know my own name, I'd better remember it. Along with any nicknames I want to respond to. The way to do it is the same way to know the hand that I hold, make an instance attribute. And the place to do that is in the __init__() method. class Hand: def __init__(self, myname): self.hand = [] # create Hand object self.name = myname def __str__(self): s = self.name + ' contains ' for x in self.hand: s = s + str(x) + return s dealer=Hand(Dealer) player=Hand(Player) -- DaveA -- https://mail.python.org/mailman/listinfo/python-list

Re: Asyncio problem, looking for advice.

Hello all,
I'm working on a project to learn asyncio and network programming. What I'm
trying to do is forward a connection from myself to another machine. Kind of
like an asynchronous python implementation of fpipe.
In a nutshell:
1 -- start a server listening on localhost
2 -- connect to server
3 -- server connects to a listening service (ssh for instance)
4 -- server handles both connections to pass traffic back and forth through
each
What I have now *kind of* works. It sends data back and forth, but when I
ssh to localhost -p 12345, i never get the password prompt. It looks like
one packet hangs out and doesn't get sent from what I saw in tcpdump.
Any help would be greatly appreciated.
Do you want to emulate `ssh -L 12345:localhost:22 host`?
Here's a link to the same code as below, just with syntax highlighting etc...

There are several issue e.g., unnecessary async(), deprecated Task()
calls but the main issue is that _handle_client() doesn't read
concurrently from the server while client writes to it.
You could use asyncio.wait() to run several tasks in parallel
[1]. Here's a forward-port.py example [2]:
#!/usr/bin/env python3
Forward a local tcp port to host:port.
Usage: %(prog)s local_port:host:port

$ python3 forward-port.py 26992:icanhazip.com:80 # start server
and in another window:
$ curl localhost:26992 # connect to it
import asyncio
import logging
import sys

Re: Fwd: Python Signal/Slot + QThred code analysis
On Fri Nov 28 2014 at 2:07:32 AM Michael Torrie torr...@gmail.com wrote: Okay, here's a reworking of the code that invokes a new QThread instance each time. Note the QThread instance has to be bound to the MainWindow so that it won't be destroyed when it goes out of scope. Also the Worker thread sends a signal with the data, so there's no need to check worker.trades and risk it being invalid data. Perhaps this would be more what you had in mind. You may want to look into asynchronous I/O as well. That does not require threads at all. Fire off a request to load a url, and then get a callback when it's done. Now it's working like a charm without any freezes. I'll reproduce this 'Worker' for other stuffs that I need to call the web, but first I have a question. Which one would be better in performance, having a single 'Worker' to call all URLs, having inside this worker functions for each stuff, or having 3~5 different workers doing different stuff. In the end I'll only print the data when I have them all. The problem is that I would have a long new_value = Signal(QThread, str, str), with more then 10 values, is it possible to pass objects here like new_value = Signal(QThread, ObjA, ObjB, ...) so that in the 'create_topic' I would get the objects and call methods in order to get all the data? This approach would be better, because I may be adding more stuff and I wouldn't need to add tons and tons of new stuff in my signal, only one object. You don't need to redo the code, I just need to know if it's a 'good approach' and if it's possible, from here I can work my way. -- https://mail.python.org/mailman/listinfo/python-list
manipulating an existing plot !
Hello, I already have a script that plots a polygon. But now I'm trying to script a python class that would enable me to import the previous plot , make instances and control it too(like specifying parameters like spacing , width, height or the like). My approach was, to create a new layout and try to import the exisiting plot and then try to make instances and manipulate it. class DerivedClass(BaseClass): def __init__(self, layout,topcell): self.layout = pya.Layout() self.layout.dbu = 0.001 self.topcell = self.layout.create_cell(TOP) l1 = layout.layer(1, 0) topcell.shapes(l1).insert(pya.Box(0, 0, 1000, 2000)) self.path = [] def add_new(self,path): self.path.append(path) How could I use layer mapping or any other method to accomplish this?

Iterate over text file, discarding some lines via context manager

Re: Fwd: Python Signal/Slot + QThred code analysis

In the end I'll only print the data when I have them all. The problem is that I would have a long new_value = Signal(QThread, str, str), with more then 10 values, is it possible to pass objects here like new_value = Signal(QThread, ObjA, ObjB, ...) so that in the 'create_topic' I would get the objects and call methods in order to get all the data? Yes you can pass objects through signals. You could pass a dict, or an instance of one of your own classes. You could also go back to your first architecture and pass in an Outpost class instance to the worker thread when instantiating it, and then the worker could use the outpost instance to perform the work, then pass it back to your handler through the signal. This approach would be better, because I may be adding more stuff and I wouldn't need to add tons and tons of new stuff in my signal, only one object. You don't need to redo the code, I just need to know if it's a 'good approach' and if it's possible, from here I can work my way. Yeah sounds alright. I'm sure there are multiple ways of doing this that would work. -- https://mail.python.org/mailman/listinfo/python-list

Re: Iterate over text file, discarding some lines via context manager
Hi
Here is a solution with a custom iterator which operate on files.
I tested it with a small file. Just a remark, there are no empty line
on a file, there is at least '\n' at the end of each lines but maybe the
last one. If readline() got an emptyline, then the end of file has been
reached.
class MyFileItr:
def __init__(self, f):
self.f = f
self.line =
def __next__(self):
while True:
self.line = self.f.readline()
if (self.line == ''):
raise StopIteration
if not(self.line.startswith('#') or self.line.isspace() or self.line == '\n'):

Why would you prefer that over a generator function, as given earlier in

Hello all,
I'm working on a project to learn asyncio and network programming.
What I'm trying to do is forward a connection from myself to
another machine. Kind of like an asynchronous python
implementation of fpipe.
In a nutshell:
1 -- start a server listening on localhost
2 -- connect to server
3 -- server connects to a listening service (ssh for instance)
4 -- server handles both connections to pass traffic back and forth
through each
What I have now *kind of* works. It sends data back and forth,
but when I ssh to localhost -p 12345, i never get the password
prompt. It looks like one packet hangs out and doesn't get sent
from what I saw in tcpdump.
Any help would be greatly appreciated.
Do you want to emulate `ssh -L 12345:localhost:22 host`?
Here's a link to the same code as below, just with syntax highlighting
etc...
http://pastebin.com/iLE4GZH3
There are several issue e.g., unnecessary async(), deprecated Task()
calls but the main issue is that _handle_client() doesn't read
concurrently from the server while client writes to it.
You could use asyncio.wait() to run several tasks in parallel
[1]
https://docs.python.org/3/library/asyncio-task.html#example-parallel-execution-of-tasks
[2] http://pastebin.com/g08YaJyz
Akira,
First, thank you very much for your response. It helps tremendously.
I have a question or two though, if you don't mind.
You said Task() is deprecated, but it's not listed as such in the
docs. Is it just that it's preferred to use other methods instead of
using Task() directly, or am I missing something?
asyncio is a provisional API [3], it may change without notice (though
it shouldn't without a reason). From asyncio docs [4]:
Don’t directly create Task instances: use the async() function or the
BaseEventLoop.create_task() method.
The reason is probably to support Trollius (asyncio for Python 2) [5].
Also, just so I can wrap my head around things, I was trying to mix
concurrent and procedural programming in the code I provided, correct?
Do you have any advice on how to avoid mixing types again in the
future?
In short, the main issue was that your code executed some parts
sequentially e.g., A then B:
yield from A
yield from B # this is not reached until A finishes
that needed to be run concurrently:
yield from asyncio.wait([A, B])
or in general, if you don't need to wait the results:
asyncio.async(A)
asyncio.async(B)
# ... yield later, to pass the control to the event loop
(Task._step/_fut_waiter dance ☯)
Ask, if you have any specific questions about the code
http://pastebin.com/g08YaJyz
There is a bug at the end. info('done') should be outside the loop
(improper indent).

You see I'd like to ignore lines which are empty, start with a #, or
are only white space. How would I write a context manager so that the
above simply becomes
with some_tricky_stuff( 'myfile' ) as items:
process( items )
I see what you're getting at, but a context manager is the wrong
paradigm. What you want is a generator. (untested)
def mygenerator(filename):
with open(filename) as f:
for line in f:
if not line: continue
if line.startswith('#'): continue
items = line.split()
if not items: continue
yield items
Now your caller simply does:
for items in mygenerator(filename):
process(items)
I think it's slightly better to leave the open outside the generator:
def interesting_lines(f):
for line in f:
line = line.strip()
if line.startswith('#'):
continue
if not line:
continue
yield line
with open(my_config.ini) as f:
for line in interesting_lines(f):
do_something(line)
This makes interesting_lines a pure filter, and doesn't care what sort
of sequence of strings it's operating on. This makes it easier to
test, and more flexible. The caller's code is also clearer in my
opinion.
BTW: this example is taken verbatim from my PyCon presentation on
iteration, it you are interested:
http://nedbatchelder.com/text/iter.html
The conditions could be combined in this case:
def iter_rows(lines):
for line in lines:
items = line.split()
if items and not items[0].startswith('#'):
yield items # space-separated non-emtpy non-comment items
with open(filename):
for items in iter_rows(file):
process(items)

Since they should never be used to *enforce* correct behaviour, but only to *verify* behaviour is correct (i.e. as a form of testing), it doesn't matter if you disable them. If I turn them off, all that happens is that the tests won't run *for me*. The software will still be just as correct, or just as buggy, regardless of the assertions. But not everyone will turn them off. Even if *everybody else* turns them off, you, the developer of the software, surely won't[1] since you're not an idiot. (Why write assertions only to never use them?) That means that whenever you run your software during the process of development, your assertions will run. In a complex, rich software application, you may not have unit tests for every possible path through the software. But if you put assertions at the intersections of paths (e.g. at the top of each loop, or the entry and exit of each function), then even if you don't have a unit test for a particular path, at least the assertions will be there to provide limited testing. In other words, correctly written assertions can provide simple but effective test coverage of 100% of your application. I stress that assertions aren't a replacement for unit testing, but they compliment unit testing: assertions can help cover code missed by your unit tests, and check that your unit tests are correct. If the user of your application disables assertions, they will be no worse off than if you didn't write those assertions at all. And if they enable assertions, then they get extended testing throughout the lifetime of the product *for free*. (Well, perhaps not *quite* for free, since assertions do have some performance cost. But very cheaply.)

New submission from Gary van der Merwe:
Currently if one has an ip address in int or IPv4Address/IPv6Address form, it
is not possilbe to create a ip_interface or ip_network from that with specific
prefix length, without first converting the address into string form, and then
appending the prefixlen
Please could an optional prefixlen argument to ip_interface and ip_network (and
the __init__ functions for their backing classes) so that one can do this.
e.g: it should work like this:
ipaddress.ip_interface(167772161, prefixlen=24)
IPv4Interface('10.0.0.1/24')
I would like to do a patch for this. I would just first like some feedback as

[issue22922] asyncio: call_soon() should raise an exception if the event loop is closed
STINNER Victor added the comment: call_soon_after_close.diff looks good but also incomplete: call_later, call_at and run_in_executor should also raise an exception if the event loop is closed. You should also add call_soon_threadsafe to the test. So for consistency this patch should grow quite a bit (unless create_connection, add_reader etc. already raise in this case). Yes, add_reader raises an exception and there is an unit test to ensure that. create_task() is a little bit special, it does not schedule immediatly a coroutine. IMO it makes sense to fail if the loop was closed, I don't see how the task can be executed if the loop was executed, so calling create_task() on a closed loop looks like a bug. I suggest to modify the following methods: - call_soon, call_soon_threadsafe - call_at, call_later - run_in_executor - create_task - add_signal_handler - subprocess_exec, subprocess_shell Did I miss something? I'm not sure that *all* asyncio methods should must call _check_closed(), it may make the code harder to read. If the basic functions like call_soon and add_reader already handle the closed status, I guess that all other methods will fail loudly, so they don't need to be modified. For example, stop() calls call_soon() and so will also raises an exception if the loop is closed. Maybe we should add almost all methods to the test checking that calling these methods on a closed loop fail. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue22922 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Martin Richard added the comment: Hi, Actually, closing and creating a new loop in the child doesn't work either, at least on Linux. When, in the child, we call loop.close(), it performs: self.remove_reader(self._ssock) (in selector_events.py, _close_self_pipe() around line 85) Both the parent and the child still refer to the same underlying epoll structure, at that moment, and calling remove_reader() has an effect on the parent process too (which will never watch the self-pipe again).
