Re: Own network protocol

[Connor]

Hi,

You can use the TML/SIDEX SDK to setup a server on a Raspberry_Pi. It 
enables peer to peer communcation beased on the Blocks Extensible 
Exchange protocol. The Python interface is easy to use and you can find 
tutorial videos on youtube, how to install it on a raspberry_py.


Search for "How to install TML/SIDEX on Raspberry Pi" on youtube.

The SDK is available on multiple platforms and it is free for personal 
projects.


Cheers,
Connor

Hello!

I am just about setting up a project with an Raspberry Pi that is connected to 
some hardware via its GPIO pins. Reading the data already works perfectly but 
now I want to distribute it to clients running in the network. Hence, I have to 
setup a server in Python.

I do not want to reinvent the wheel, so I am asking myself whether there is a 
good practice solution. It should basically work such that once value (can be 
either binary or an analog value) has changed on the server, it should send the 
update to the connected clients. At the same time, it should be possible for 
the client to send a particular request to the server as well, i.e., switch on 
LED X.

What kind of protocol do you recommend for this? UDP or TCP? Do you recommend 
the use of frameworks such as twisted?

Thanks for your input!

error handling in multithreaded extension callbacks

[Connor]

Hi,

In my extension I'm calling python functions as callbacks from a thread 
generated in an external module.

This works very well, but I'm not sure about the error handling.

1. Normally the python interpreter exits if it runs on an unhandled 
error. Is this the preferred standard behavior for this case too ?

2. How can I implement this in my error handling ?

Here is my code so far. If an error happens in the python code it is 
printed to stderr, but the python script is still running in the main 
thread.


void FUNC_C_DECL coreCommandReadyCallback(TML_COMMAND_HANDLE cmd, 
TML_POINTER data)

{
  // Calling Python out of a non- python created thread
  PyGILState_STATE gstate;
  try {
gstate = PyGILState_Ensure();

PythonCallbackData* callbackData = (PythonCallbackData*) data;

PyObject *arglist;

PyObject *pythonCBFunc = callbackData->pCBFunc;
/* Time to call the callback */
arglist = Py_BuildValue("(LO)", cmd, callbackData->pCBData);
PyObject* result = PyEval_CallObject(pythonCBFunc, arglist);
Py_DECREF(arglist);

if ( PyErr_Occurred() ) {
  PyErr_Print();
  PyErr_SetString(PyExc_TypeError, "PyErr_Occurred");
}


// Release calling Python out of a non- python created thread
PyGILState_Release(gstate);
  }
  catch (...) {
printf ("An Exception Happened\n");
  }
}

Cheers,
Connor

Copy-on-write when forking a python process

[John Connor]

Hi all,
Long time reader, first time poster.

I am wondering if anything can be done about the COW (copy-on-write)
problem when forking a python process.  I have found several
discussions of this problem, but I have seen no proposed solutions or
workarounds.  My understanding of the problem is that an object's
reference count is stored in the "ob_refcnt" field of the PyObject
structure itself.  When a process forks, its memory is initially not
copied. However, if any references to an object are made or destroyed
in the child process, the page in which the objects "ob_refcnt" field
is located in will be copied.

My first thought was the obvious one: make the ob_refcnt field a
pointer into an array of all object refcounts stored elsewhere.
However, I do not think that there would be a way of doing this
without adding a lot of complexity.  So my current thinking is that it
should be possible to disable refcounting for an object.  This could
be done by adding a field to PyObject named "ob_optout".  If ob_optout
is true then py_INCREF and py_DECREF will have no effect on the
object:


from refcount import optin, optout

class Foo: pass

mylist = [Foo() for _ in range(10)]
optout(mylist)  # Sets ob_optout to true
for element in mylist:
optout(element) # Sets ob_optout to true

Fork_and_block_while_doing_stuff(mylist)

optin(mylist) # Sets ob_optout to false
for element in mylist:
optin(element) # Sets ob_optout to false


Has anyone else looked into the COW problem?  Are there workarounds
and/or other plans to fix it?  Does the solution I am proposing sound
reasonable, or does it seem like overkill?  Does anyone foresee any
problems with it?

Thanks,

Re: Pythonic infinite for loop?

If I understand  your question correctly, what you want is probably
something like:

i = 0
lst=[]

 try:

   i += 1

Re: De-tupleizing a list

[John Connor]

itertools can help you do this too:

import itertools
tl = [('0A',), ('1B',), ('2C',), ('3D',)]

itertools.chain.from_iterable(tl)


list(itertools.chain.from_iterable(tl))
['0A', '1B', '2C', '3D']


Checkout http://docs.python.org/library/itertools.html#itertools.chain
for more info.

I don't help trolls.

And I don't think you could run Linux if your life depended on

You'd actually have to take a break from running your mouth on
hundreds of groups under dozens of aliases to do some homework.

And are attacking Linux in your original subject:

With the typical display of non-literacy of a troll: No caps

Your User-Agent string in your headers reads Windows, until
this thread, where it is modified only to say Linux instead of
Windows, but otherwise the same newsreader.

And there are virtually no Linux groups in your posting history 
for the last year.

You are a stinking troll and you will wear a gag when you are
in my newsreader. Nor will anyone be allowed to send replies to
yourarticles to my newsreader.

Regardless of which alias you are hiding behind at the moment,

#  (2 Points) Write a python function howMany(item,lst) which accepts
an item and a lst of items and returns the number of times item occurs
in lst. For example, howMany(3,[1,2,3,2,3]) should return 2.

# (2 Points) Write a python function upTo(n) which accepts a non-
negative number n and returns a list of numbers from 0 to n. For
example, upTo(3) should return the list [0, 1, 2, 3].

# (2 Points) Write a python function duplicate(lst) which accepts a
lst of items and returns a list with the items duplicated. For
example, duplicate([1,2,2,3]) should return the list [1, 1, 2, 2, 2,
2, 3, 3].

# (2 Points) Write a python function dotProduct(a,b) which accepts two
lists of integers a and b that are of equal length and which returns
the dot product of a and b. I.e., the sum a0 * b0 + ... + an-1 * bn-1
where n is the length of the lists. For example:

dotProduct([1,2,3],[4,5,6]) is 1*4 + 2*5 + 3*6 = 4 + 10 + 18 = 32

# (2 Points) A pair (exp0, exp1) is a combination of expressions that
are attached together by their joint membership in the pair. For
example:

>>> (1+2, 'This')
(3, 'This')

A component of a pair can be obtained using an index in brackets as
with lists (and strings!). For example:

>>> (33,44)[0]
33

Write a function zip(lst1, lst2) such that zip accepts two equal
length lists and returns a list of pairs. For example, zip(['a', 'b',
'c'], [10, 20, 30]) should evaluate to the list [('a', 10), ('b', 20),
('c', 30)].

# (2 Points) Write a function unzip(lst) such that unzip accepts a
list of pairs and returns two lists such that lst == zip(unzip(lst)).
For example, unzip([('a', 10), ('b', 20), ('c', 30)] should evaluate
to the pair (['a', 'b', 'c'], [10, 20, 30]).

# (2 Points) Write a python function isAscending(lst) which accepts a
non-empty list of integers and returns True if the numbers in the list
are in ascending order. Otherwise it should return False. For example,
isAscending([1]) should evaluate to True while isAscending([1,2,2])
should return False.

Format Logfile Name with logging.ini

[connor . r . novak]

In an effort to clean up my python logging practices when creating libraries, I 
have begun reading into "Advanced Logging" and converting my logging practices 
into logging configuration `.ini` files:

[link](https://docs.python.org/3.4/howto/logging.html#configuring-logging)

My question is: When defining a FileHandler in a `.ini` file, all of the 
examples that I've seen hardcode the name and location of the log file. In the 
code snippet below, `python.log` is hardcoded into the `.ini` file:

```
[handler_hand02]
class=FileHandler
level=DEBUG
formatter=form02
args=('python.log', 'w')
```
[code reference 
link](https://docs.python.org/3.4/library/logging.config.html#logging-config-fileformat)

Desired Behavior:
On each run of the program, a new logfile is created in the `logs/` directory 
named "_program.log".

Current Behavior: 
The format in the example above overwrites a single file called "python.log" on 
each run, which is not the desired behavior.

Question: Is there a standard procedure for using .ini files to create a new 
logfile prepended with the current Unix timestamp on each run of the program?
