ExcelMailer 0.2
It is a pleasure to announce this first public release of ExcelMailer.
ExcelMailer is a small os-independent command line business tool for
emailing personalized messages with attachments. Data and options are
specified via an Excel file and the message content via plain text or
HTML file templates. For each data row in the Excel file ExcelMailer
prepares and sends, when explicitly requested, a personalized MIME
email message and its attachments if any.
Highlights:
- The text message may be in plain text or in HTML or in both i.e. in
HTML with an alternative plain text version.
- May define any number of data columns (only to is required) that are
then all accessible in the message templates with ${ column heading }.
- Rich and flexible set of options, that may be conveniently saved in
the Excel file itself as well as be explicitly overridden on the
command line.
- Automatic recognition of input text encodings. Output text is always
encoded in UTF-8.
- Extensive data validation before sending any messages. No emails are
sent unless explicitly requested and all data checks pass. No error
goes silent.
- Data rows can be tagged, for test runs or selective re-runs.
- All actions, such as sending of an email, are logged to a file named
${ excel file }.log, placed alongside the Excel file.
Special thanks to John Machin, for the xlrd package, to Bryan
Niederberger, for his recipe making using xlrd even easier, and to Skip
Montanaro, for some sample code to facilitate handling of input
encodings.
ExcelMailer is GPL3-licensed, and is available from:

Any and all comments, problem reports, suggestions welcome!
Thanks and all the best,
mario

Re: Modify arguments between __new__ and __init__

When you call a new-style class, the __new__ method is called with the

I would like to modify the arguments after the __new__ method is called

class Spam(object):

... print __new__, args
... x = object.__new__(cls)
... args = ['spam spam spam']

but naturally it doesn't work:
s = Spam('spam and eggs', 'tomato', 'beans are off')
__new__ ('spam and eggs', 'tomato', 'beans are off')
__init__ ('spam and eggs', 'tomato', 'beans are off')
Is there any way to do this, or am I all outta luck?

The ususal way is to override the __call__ method of the metaclass.

Re: Inter-process communication, how? Part 2

To make it simple and not have to deal with the 8 queens problem that is different with the 5 queens one, I'll ask in a different way. I am not familiar with implementing in Python such terms as standard depth-first search of the solution space, permutation, recursion, 'canonical' form, ...

Local variables in classes and class instantiation
Hi all,
I just started using Python. I used to do some Java programming, so I am
not completely blank.
I have a small question about how classes get instantiated within other
classes. I have added the source of a test program to the bottom of this
mail, that contains 3 methods within a testclass that each instantiate
the same class and bind it to a local variable. My understanding was,
that the local variable gets garbage collected as soon as the method
goes out of scope. Thus I would expect the local variable 'cpu' in these
methods to be independant and create different instances of the class CPU.
Still, when I execute all three methods, I get two instances that are
equal and the third is different.
Is there some circomstance that makes two object creations result in the
same object?
= output
Output from the (test)program is:
cpu class = cpu.CPU instance at 0x8244eec
.cpu class = cpu.CPU instance at 0x8244eec
.cpu class = cpu.CPU instance at 0x8244f0c
.

I think it is not straitforward. Single level function which generator

Not just impractical, there are plenty of situations where you simply
cannot do that at all.
Here's a greenlet example (from
http://socal-piggies.org/presentations/grig/2005_07_21/):
from py.magic import greenlet
import xml.parsers.expat
def send(arg):
greenlet.getcurrent().parent.switch(arg)
def start_element(name, attrs):
send(('START', name, attrs))
def end_element(name):
send(('END', name))
def char_data(data):
data = data.strip()
if data: send(('DATA', data))
def greenparse(xmldata):
p = xml.parsers.expat.ParserCreate()
p.StartElementHandler = start_element
p.EndElementHandler = end_element
p.CharacterDataHandler = char_data
p.Parse(xmldata, 1)
def iterxml(xmldata):
g = greenlet(greenparse)
data = g.switch(xmldata)
while data is not None:
yield data
data = g.switch()
if __name__ == __main__:
for data in iterxml(somexmldata):
# do something with data
The greenlet here calls expat, but the 'yield' happens inside an expat
callback. To get this to work you would need to rewrite expat to use its
callback as a generator. Expat is coded in C, so you also need to find
some way to get it to save the state of the C functions when it has
yielded.
I think this example should answer Arnaud's question (In fact it is not
clear to me at the moment what can be done (sensibly :) with the OP's
Fiber class that cannot be achieved with the run() function I
suggested.) Arnaud's run function cannot be used by anything which needs
to save C stack state.
I am happy if I could use convenient coroutine features via standard
or simple extension library. py.magic.greenlet may be what I'm
looking for, but I wonder why this is named magic :-)
I think it is called magic because it does something which is at first
glance impossible: saving the C stack state as well as the Python stack.
Possibly it does something underhand to achieve an impressive effect.
I haven't looked at the implementation to see how it does it: creating
threads and then scheduling them cooperatively would be one way but I
expect it just switches the C stack around between different areas of
memory.
A long time ago I ported the BCPL coroutine library and there is one
function in the middle (the one which does the stack switch) that
definitely felt like magic.
One interesting question raised by all this is whether those of us using
Windows can usefully call Microsoft's Fiber functions through ctypes and
get the benefit of coroutines without having to load any additional C
extensions at all.

If you compare the teletype to a tube it was lame. But that's not the
right comparison. The Fortran technology was cards, punched on a card
punch, carried to the operator. Wait your turn (hours more commonly
than minutes). Get a report off the line printer. Repunch the

Indeed, the teletype with line numbers was a giant step forward. No

Or, redirect all Workers' stdout to stdio of Manager. If there was only one Worker I could use a pipe, right? But if there are more than one Worker, what to do? I found something called named pipe which seems rather complicated.

The DLL is removed by the Windows Installer when its usage counter drops to 0. There is no need to worry ;) I am not worrying about an orphaned DLL. The Problem is that this way the Python DLL is being made available for 3rd party applications, which possibly need a version of Python which is compiled using another compiler. We are embedding Python into our application which gets compiled using MSVC 8.0. We like to link dynamically, so the Python interpreter is not statically linked into the program. The Python DLL from the Python installer in the Windows system32 folder is compiled using MSVC 7.1. Our current solution to the problem is modifying the Python build process to produce our Python DLL with a filename containing also the patchlevel of the version number i.e. python251.dll instead of python25.dll. This way we can be sure that *our* Python DLL gets loaded. This works fine. I was just curious, if there is a special reason for placing the Python DLL into the system32 folder. So COM seems to be the answer. Thank you, Markus -- http://mail.python.org/mailman/listinfo/python-list
Releasing malloc'd memory using ctypes?
I am starting to experiment with ctypes. I have a function which returns a pointer to a struct allocated in heap memory. There is a corresponding free function for that sort of struct, e.g.: from ctypes import * cdll.LoadLibrary(libthing.so) c_thing = CDLL(libthing.so) class THING(Structure): _fields_ = [(name, c_char_p), (value, c_int)] get_thing = c_thing.get_thing get_thing.restype = POINTER(THING) free_thing = c_thing.free_thing So I call get_thing() and get back this ctypes wrapper for a pointer to a thing. I can extract the name and value elements from the thing instance just fine: thing_p = get_thing() thing = thing_p.contents print thing.name, =, thing.value Now I need to call free_thing. What do I pass it? thing_p? Some attribute of thing_p? Something else altogether? The ctypes module docs seem to be strangely silent on the question of freeing heap memory which you've received from the underlying library's functions.

Re: How to get Python to default to UTF8
However, the situation is still unacceptable to me because I often make mistakes and it is easy for me to miss places where encoding is necessary. I rely on testing to find my faults. On my development environment, I get no error message and it seems that everything works perfectly. However, once ported to the server, I see a crash. But this is too late a stage to catch the error since the app is already live. If you want to check whether there is indeed no place where you forgot to properly .encode, you can set the default encoding on your development machine to undefined (see site.py). This will give you an exception whenever the default encoding is invoked, even if the encoding would have succeeded under the default default encoding (ie. ascii) Such a setting should not be applied a production environment. Can you elaborate on where to look to see what stdin/stdout encodings are set to? Just print out sys.stdin.encoding and sys.stdout.encoding. Or were you asking for the precise source in the interpreter that sets them? All inputs are coming at my app either via html forms or input files. All output goes either to the browser via html or to an output file. Then sys.stdout.encoding will not be set to anything. Regards, Martin -- http://mail.python.org/mailman/listinfo/python-list

Ah, perhaps Python should similarly limit function call nesting to one level so as to keep things simple and encourage reuse. Bit of a grumpy response? ... and a straw man argument ? Generators can be used to build co-operative multitasking (eg WSGI is implicitly co-op multitasking), whereas function calls are used to build sequential code. I agree for sequential code generators being single level can be rather limiting. However, the thread is about co-operative multitasking. Decades of experience has shown that the best way to build concurrent systems (MASCOT[1], Unix, MPI, Occam, Erlang, even VHDL some mashups) is to have small things loosely connected. Generators encourage making little things which then encourages connecting them together. It seems, to me, to help. (Which is all I said really) [1] Only recently heard about MASCOT - best reference is here: http://async.org.uk/Hugo.Simpson/ (MASCOT is over 30 years old... (fun thing of the week that I've been pointed at for me :-) ) It's the same basic ethos that makes Unix pipelines useful, and is why WSGI is useful. Simple transformational things which work best when they're pipelined together. The fact that you can't trivially nest generators in a way that feels nice[2] IMO naturally encourages making small things, which end up being reusable. [2] I don't personally feel for i in X(): yield i is particularly nice. To be clear - I REALLY didn't like the fact that generators were single layer when I first saw them - it seemed a huge limitation. (Indeed as huge a limitation as only having single level function calls, or only single layer of nesting for namespaces, etc)... I even asked a question [3] on that point before choosing python to write Kamaelia in... The fact that it's been a benefit rather than a problem rather surprised me. [3] http://groups.google.com/group/comp.lang.python/tree/browse_frm/thread/fcd2709952d23e34/8a0b9ba0e3beb108 That's rather different from the recursion limit (which is a limit on function call depth) that really *has* been a pain at times. (Something which tail recursion would really help with) Incidentally, you may note that you helped me back then (which I'm thankful for :-), so you can kinda view this as me reporting back actually, it's turned out to be helpful rather than a pain :-) Took a while to figure that out though ;) Your mileage may vary :) Incidentally, it was probably your response (message 7) in that thread that was responsible for me deciding to see where things could go by trying python :-) Merry Christmas, Michael.

[issue1760357] ZipFile.write fails with bad modification time
Alan McIntyre added the comment: At the moment I don't have a Windows machine available, but on my Mac, time.localtime doesn't seem to mind interpreting negative input values. So I doubt that forcing timestamps to be non-negative is the way to fix this. I poked around a bit in the current 2.6 source, and it seems to me that in this case the Windows XP localtime function doesn't like a timestamp value that was generated by the same platform's stat function. It seems like raising a ValueError is the correct thing for the time module to do, since it relies on the platform to do the conversions; what should zipfile.writestr do? I don't like the idea of silently using some dummy timestamp if the conversion of os.stat results fails, and I can't think of an alternative at the moment. -- nosy: +alanmcintyre _ Tracker [EMAIL PROTECTED] http://bugs.python.org/issue1760357 _ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue1650] IDLE: help() displays output on the wrong shell
Kurt B. Kaiser added the comment: Yes, and it does on linux, also. Someone changed the way help() works. Since the help listing is often extensive and clutters up the shell, I'm thinking that the best solution would be to pop up a new window. I haven't got around to addressing either the bug or a new design. __ Tracker [EMAIL PROTECTED] http://bugs.python.org/issue1650 __ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue1647] IDLE messes around with sys.exitfunc
Kurt B. Kaiser added the comment: It was done for VPython support, as described in the docstring in run.py:exit(). What are you doing, removing sys.exitfunc from 2.6? The 3.0 run.py code was changed to use atexit._clear(). __ Tracker [EMAIL PROTECTED] http://bugs.python.org/issue1647 __ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
