ANN: SCSIPYTHON added to Sourceforge
I have updated and moved my SCSI diagnostic tools from starship to sourceforge. I will be still maintaining these files at both locations as long as starship exists. These tools allow low level tests to be conducted on storage devices under the Windows operating system. These routines access all storage devices through the Windows SCSIPASSTHROUGH layer, which maps all storage devices (SCSI,IDE/ATA,USB,PCMCIA,DVD,CD) to look like a SCSI device that is accessed using SCSI command descripter blocks. The move to Sourceforge also places the sourcecode,and files under CVS control.

EdWhyatt [EMAIL PROTECTED] wrote:
Ok, totally unrelated, and on that subject, I will make sure I always
have a recipient in the To: field. - hey it works if I do that anyway!
OK, I'm a bit concerned that the answer to the original question has been
lost. The difference between the SMTP envelope and the message content is
an important one, and that's the key point here. If this is obvious to
everyone involved, I apologize.
The actual content of an e-mail message, including the message headers, has
absolute nothing to do with the delivery of the message. That's all just a
convention that we have developed to allow messages to be read by humans.
All of the To:, Cc:, and Bcc: headers are there for you, the human (well,
and your helper, the e-mail reader). SMTP doesn't care one whit about
them.
The smtplib.sendmail method has three parameters: sender, recipient list,
and content. SMTP could not care less about the content. You can skip ALL
of the headers (as long as you leave a blank line), and it will be
delivered just fine. It won't be RFC 822 compliant, but SMTP doesn't care.
SMTP is RFC 821. Your message will get delivered, although the recipients
e-mail reader might croak on it.
SMTP cares about the sender and the recipient list. Going off the deep
end, consider this Python snippet:
msg = \
To: [EMAIL PROTECTED]
Subject: This is the RFC-822 part
Hello, mom!
s = smtplib.SMTP('localhost')
s.sendmail( [EMAIL PROTECTED], [[EMAIL PROTECTED],[EMAIL PROTECTED]],
msg )
Note that the To: address is not listed in the sendmail parameters. Now,
here is a simulated SMTP script for this message:
MAIL FROM: [EMAIL PROTECTED]
RCPT TO: [EMAIL PROTECTED]
RCPT TO: [EMAIL PROTECTED]
DATA
To: [EMAIL PROTECTED]
Subject: This is the RFC-822 part
Hello, mom!
.
Those first four commands are SMTP, generated from the first two parameters
to sendmail, and those are the ONLY things that determine where this
message will be delivered. The are called the envelope. Note that the
actual recipients' names do not appear in the message body AT ALL. At the
other end, Mr. One at Foo, Inc., might be surprised to receive a message
that does not appear to have been addressed to him, but SMTP doesn't care.
So, the way a BCC works is that the address goes into the envelope (in the
to_addrs list), but not in the message body.

Agreed. Per-instance descriptors could be interesting (that's why the
subject line caught my attention).
But your solution involves a custom __getattribute__ in the class, which
I would always avoid if possible (and I gather you're uneasy about it too).
I'm not uneasy about overriding __getattribute__, just about overriding
it that way -
Here, I don't see why that's better than having a descriptor in the
class and, if it needs per-instance behavior, then make it dependent on
something provided by the instance.
Each instance will need it's own set of descriptors. The class is used
as a decorator for many controller functions. The descriptors are used
to encapsulate some gory implementation details about how to get such or
such object from the framework (they of course depend on instance
specific data, but that's not the point).
e.g.,
class DummyDescriptor1(object):
def __get__(self, obj, objtype=None):
if isinstance(obj, objtype):
return obj.foo.__get__(obj)
else:
return self
class MyClass4(object):
baaz = DummyDescriptor1()
def __init__(self, foo, bar = None):
self.foo = foo
self.bar = bar
This would imply a decorator subclass and a descriptor subclass for each
and every controller function - which is what I'm trying to avoid.

Thank you Serge for this generous reply, Vectorized code seems a great choice to compute the distance. If I understand well, vectorized code can only work when you don't need to access the values of the array, but only need to know the indices. This works well for the distance, but I need to access the array values in the openness function. As regards array.array, it seems a bit complicated to reduce all my 2D arrays to 1D arrays because I am working with the gdal library, which works only with 'numeric' arrays.

I'm currently playing with some (possibly weird...) code, and I'd have a

Now the question: is there any obvious (or non-obvious) drawback with
this approach ?
Don't know if this matters, but if you override __getattribute__, you'll
slow down all attribute accesses to this object.
Yes, I know, but this shouldn't be a major annoyance here.
If this matters, you
could write something like:
class MyClass(object):
def __init__(self, bar=None):
if bar is not None:
self.bar = bar
def __getattr__(self, name):
if name == 'baaz':
return self.bar
elif name == 'bar':
return 'no bar'
Don't focus on the dummy example I gave - the real descriptors are doing
something a bit less stupid !-)
Could you explain again why you don't want baaz to be a class-level
attribute?
Because the class is a decorator for many controller functions, and each
controller function will need it's own set of descriptors, so I don't
want to mess with the class.
Think of the decorator as a prototype, each controller function
customizing it according to it's need - this customisation including
the decorator instance attaching descriptors and methods to itself
according to parameters passed at __init__ time. The decorator instance
also passes itself as first arg to the controller function - which then
practically become an instance method too.
Don't tell me, I know this is a somewhat weird architecture, and it
could mostly be done with more conventional subclassing. BTW, this was
how a first implementation worked, and it required almost twice more
code than the new one I'm experimenting, without being half as flexible.
As I said, it's mostly syntactic sugar, but what, I'm lazy enough to
spend time on writing code that will allow me to write less code in the
end !-)

Strange metaclass behaviour
Hi, I think I have discovered a problem in context of metaclasses and multiple inheritance in python 2.4, which I could finally reduce to a simple example: Look at following code: class M_A (type) : def __new__ (meta, name, bases, dict) : print M.__new__, meta, name, bases return super (M_A, meta).__new__ (meta, name, bases, dict) class M_B (M_A) : pass class A (object) : __metaclass__ = M_A class B (object) : __metaclass__ = M_B class D (A, B) : pass One would expect that either 1) D inherits the metaclass M_A from A 2) or python raises the well known Metatype conflict among bases error Instead, if you run this code, you get the following output: M.__new__ class '__main__.M_A' A (type 'object',) M.__new__ class '__main__.M_B' B (type 'object',) M.__new__ class '__main__.M_A' D (class '__main__.A', class '__main__.B') M.__new__ class '__main__.M_B' D (class '__main__.A', class '__main__.B') This means that when class D gets defined, the __new__ from M_A get executed twice (first from M_A, then from M_B), which should not happen. This suggests that either 1) cooperative supercalls do not work here 2) the metaclass of EACH of the bases of D does it's work independently when D is defined.

Re: Remote teamwork anecdotes
On Mar 20, 2006, at 9:51 PM, Alex Martelli wrote: While what *I* want, ideally, is pair programming -- somebody sitting right at my side, alternating with me in controlling keyboard and mouse, and in verbalizing what he or she is coding -- that's part of the huge productivity boost I observe in a co-located team... that pair programming works SO much better that way, that even with the best remote cooperation tools (subethaedit onwards). I've often noticed that programming for me is akin to composing music. Now let me start by saying that while I can hum pretty well, I'm not a musician of any sort, so this is based upon the experiences related to me by others who are (btw, there seems to be a very large overlap between programmers and musicians...). I can be mulling over a particular problem for hours, sometimes days, and do nothing but write some pseudo-code or a couple of trial programs that don't really do what is needed. Then, at some unpredictable point, clarity sets in and I see the solution. After that, it's just a matter of transferring that into code (for which Python is by far the best language, as it doesn't get in my way). The people I know who write music tell me of a similar process: they play a few bars or write a few words, but it doesn't feel quite right. Then either a particular musical hook comes to mind, or a set of words that solidifies the image of what they were feeling, and after that the song is written in their head and just needs to be transferred to tape (or bits, as is more common these days). I can't wake up one day and plan my day like this: 9-12, write some killer algorithm; 12-1, run errands and eat lunch; 1-3, add algorithm to existing code and refactor; etc. Nor can the musicians I know plan of writing the first stanza of a song in the morning, the second after lunch, and the chorus in the evening. The other similarity is that some musicians tend to be more creative when off by themselves, while the rest seem to feed off of jamming together with others. Most of them strongly prefer one or the other; rarely do they employ both. The comparison to programmers would be that I seem to resemble the former type, while you seem to resemble the latter. I strongly agree on the benefit of code review, though, especially in my case where things tend to get written more or less unconsciously. While the main problem may be addressed well, there are either side/end cases that still need to be addressed, or there is an opportunity to refactor to make it fit in much better with the project as a whole. A partner who is not emotionally immersed in the code can usually see these things better than the person who created the code. Wanna talk debugging? I think solo debugging is even worse than solo programming -- when I just CAN'T have a debugging partner for a sufficiently nasty bug (race conditions are the worst, but there are many other categories vying for that title;-), I'll turn to one of my beloved plushies (I'm firmly convinced the baby tiger is by far the most effective debugging partner for most bugs, though Tux the Penguin has a knack for helping spot bugs that aren't MY fault but rather the compiler's c -- since I've been using Python for most of my coding for years, poor Tux hasn't seen much action recently) -- I talk out loud to the plushy-partner to make narratives out of expected and observed occurrences. But a *LIVE* partner, actively checking out the coherence of my narratives and challenging them and proposing alternatives, is 10 times more effective... the plushies don't even talk back (except in debugging sessions that have gone on for *FAR* too long;-). OK, we part ways on the plushie thing, but here I have to agree with you: a second set of eyes (and brain patterns) helps immeasurably when debugging. I think the key here is having to explain what you did and what you thought the code should have done to someone else clarifies the problem, whether it's explaining it to someone else in the room, or trying to explain it in an email to a list like this. I can't even begin to count the number of times that I've been stuck, and decided to post the problem to a list for help, and in the process of composing the email, figured out what my mistake was! Those netiquette guidelines for posting intelligently aren't to help the readers of the post; they're to help you form your scattered thoughts into a coherent picture, and more often than not, if it's a bug that I've created rather than a gap in my understanding, the process of writing the email is all I need. I guess if there's a point to all of this, it's that good programming is a creative process, and that you need to identify what works and doesn't work for you. There is no one-size-fits-all approach that is the best.
Building files within a package
Hi All, I am creating a python package that contains a whole pile of functions that build lookup tables. Since these lookup tables will not be changing, I would like to have setup.py create a lut_static.py fie from the lookup table code (lut.py). What is the best way to do this so that when I install the package the static tables get build? It basically looks like this foo-py-0.1 setup.py foo lut.py lut_static.py - want to generate this from lut.py For development, it is easy enough for me to have a Makefile in foo that creates lut_static.py when ever lut.py is changed, but I would like to make setup.py handle this so if someone tweaks the lut.py and reinstalls it, they don't have to know about foo/Makefile Thanks! -kurt -- http://mail.python.org/mailman/listinfo/python-list

Most of the other commandments can be ignored while coding Python, but the 7th certainly applies here. http://www.lysator.liu.se/c/ten-commandments.html As I've written before, the ISO 8601 spec contains many variations in date formats. Making a full ISO 8601 parser is probably possible if we ignore time deltas, but it's hardly worth the effort. Writing something that parses a few percent of the possible ISO 8601 messages and calling that an ISO 8601 parser seems silly to me. With code like Skip's above it's obvious what kind of strings are handled. In typical applications, one such format is enough, and this needs to be properly specified. In a recent case I wrote the spec like this: The timestamp shall be an ISO 8601 combination of UTC date and time with complete representation in extended format, with representation of fractions of seconds with up to six decimals preceeded by a full stop as decimal sign. E.g. 2005-06-20T13:42:55.2425Z Despite my verbosity here, someone who didn't follow the example, would still be able to write ISO 8601 strings following the requirements above that we won't parse, since I didn't actually write that dates should be written as year-month-day.

Re: Strange metaclass behaviour
Christian Eder wrote:
Hi,
I think I have discovered a problem in context of
metaclasses and multiple inheritance in python 2.4,
which I could finally reduce to a simple example:
Look at following code:
class M_A (type) :
def __new__ (meta, name, bases, dict) :
print M.__new__, meta, name, bases
return super (M_A, meta).__new__ (meta, name, bases, dict)
class M_B (M_A) : pass
class A (object) : __metaclass__ = M_A
class B (object) : __metaclass__ = M_B
class D (A, B) : pass
One would expect that either
1) D inherits the metaclass M_A from A
2) or python raises the well known Metatype conflict among bases
error
No, there is no conflict in this case: since M_B is a subclass of M_A,
the
metaclass of D is M_B. I don't think this is bug either: the fact is
that
type.__new__ works differently from object.__new__, so that it is
called twice in this case. Not sure if it could be avoided.
Speaking of the metatype conflict, I realized a while ago that it is
possible
to avoid it automatically even at the pure Python level, without
changing
the C code for type.__new__. However, the solution is too complicate.

``noconflict`` provides the ``safetype`` metaclass, the mother of
conflict-free
metaclasses. I you do
from noconflict import safetype as type

If you override ``__new__`` when you derive from ``safetype``,
you should do it cooperatively.

Your solution is a nice workaround, but in a quite huge and complex class framework with a lot a custom metaclasses you don't want this code in each __new__ function. And in fact each __new__ which does not contain this fix-code (and which is not completely side-effect free) might break if someone adds additional classes deeps down in the inheritance hierarchy (which is exactly what happened for me). And this is clearly not what one should expect in context of multiple inheritance and cooperative supercalls.

Given the requirements, did you mean taking the *union* and swapping states? Or maybe swapping states first, and then taking the intersection? Whatever the requirements were. Take your pick. :-) Then you can use the resulting automaton to efficiently enumerate S^n - W. In the above case, the resulting FSM would have just three states. I don't see immediately how exactly this is going to work. Unless I'm very much mistaken, a FSA in the classical sense will accept or reject only after the whole sequence has been consumed, and this spells exponential times. Exponential in respect to what? You just recursively walk the automaton for every word of length n, so at most you'll have to check every word in S^n once. Hence, the complexity is not worse than the generate and test approach (it's in fact better, since testing is trivial). However, if the result set is simple (as in the example), then the result FSM will have states that won't have transitions for every letters, so I guess the average case will be a lot better. For improved asymptotic complexity in this case, you need to be able to at least reject in mid-sequence, One can do that if there is no valid transition out of some state. I guess one could even optimize on that: In the minimal automaton, every state has some transition sequence that will end up in a final state. Annotate each state with the minimum number of steps for such a sequence. While walking the automaton, keep the maximum number of letters to produce in a variable. If this number is small then the number in the annotation, stop and backtrace. This should guarantee that only those states are visited that really produce some output. - Dirk -- http://mail.python.org/mailman/listinfo/python-list

Re: encoding problems (é and è)
Seems to work fine for me.
x=éÇ
x=x.replace('é','E')
'E\xc7'
x=x.replace('Ç','C')
x
'E\xc7'
x=x.replace('Ç','C')
x
'EC'
You should also be able to use .upper() method to
uppercase everything in the string in a single statement:
tstr=ligneA.upper()
Note: you should never use 'str' as a variable as
it will mask the built-in str function.

That shouldn't be a problem: you can use stick with Word for editing the documents and just use OpenOffice to do the conversion. Duncan, I was just trying the printing thing. When installing Adobe Acrobat, it installs a printer called Adobe PDF, and I have been trying to print to there, but the Save window keeps popping up. I need to figure out a way to keep it in the background. I'm afraid its a while since I used Acrobat to generate PDF files. I think there are configuration options to tell it to do the conversion automatically and not prompt you, but I can't remember where. -- http://mail.python.org/mailman/listinfo/python-list

Wouldn't it be nice to say

But then you have to split tokens_str again.
id, tokens_str = line.split(',', 1)
tokens = tokens_str.split(',')
Sorry, it wasn't clear that you needed the tokens from the original post.
If you're interested in this, the best route is to write up a PEP and
provide an implementation. The new AST in Python makes this kind of
thing a bit easier.

Re: Per instance descriptors ?

Because the class is a decorator for many controller functions, and each controller function will need it's own set of descriptors, so I don't want to mess with the class.

That is, you want something like: @my_decorator def f(...): ... f.foo # calls f._get_foo() in another post, bruno at modulix wrote: This would imply a decorator subclass and a descriptor subclass for each and every controller function - which is what I'm trying to avoid. So you only want one decorator? Doesn't that mean that all functions will have the same attributes? But if that were true you would only need one descriptor for all controller functions, so I must not be understanding that right. Can you give a little more realistic code sample? I'm still not sure what it is you really want to do. Don't worry about showing the implementation you're thinking of. Just show me how you want to use these things and what it ought to look like.

Which means that if the list has a length of five, the len(l) 6 is true, and appending makes it len(l) == 6 - which then will fail your condition.
