For something this simple, what do they offer above the basic socket module? I know that sounds critical but it's not meant to be; I've never looked into either, as I've grown up using the BSD socket APIs (in C, 80x86 assembly, C++, REXX, Java, Pike, and Python, on DOS (I think), OS/2, Windows, and Linux... and possibly other languages/platforms that I've now forgotten), and am comfortable with them; but for someone who hasn't been in networking for two decades, is there a noteworthy ease-of-starting difference? Bear in mind that use of a framework locks you in to that framework and its ecosystem (so, most likely, language), while grokking sockets themselves gives you the freedom to move as required.

KeyboardInterrupt in Subproccesses
All: I am maintaining a program in Python 2 and need to send it a KeyboardInterrupt to close it. Unfortunately, the program is used as a subprocess in a wrapper subprocess, and so I cannot just directly press CTL-C; I have to use a signal. When I run the program "bare" (not in a subprocess), I have found that raising a SIGINT (kill -2) raises a KeyboardInterrupt in the program. But when I run the program in the wrapper process, kill -2 no longer has any effect (whether it is raised by the wrapper or externally). Why is that the case? Does Python's interpretation of SIGINT as a KeyboardInterrupt only obtain when the program is run in a terminal? Is there something else I'm missing? Bonus points: Is this behavior the same for Python 3? MCL -- http://mail.python.org/mailman/listinfo/python-list
Messages to Python-List aren't posting
All: I've been having trouble with all three Python mailing lists (python-list, python-dev, python-ideas). This has been going on for about a month.

This just came through, timestamped 11.5 hours ago. I don't usually have this problem. Looking at your Received headers, in reverse order: Date: Thu, 18 Jul 2013 16:30:51 -0400 - timestamp of your mail Thu, 18 Jul 2013 13:30:51 -0700 (PDT) - you posted it via HTTP Thu, 18 Jul 2013 22:31:39 +0200 (CEST) - it reached python.org Fri, 19 Jul 2013 09:56:14 +0200 (CEST) - it began delivery to my address Fri, 19 Jul 2013 00:56:15 -0700 (PDT) - it reached gmail and me. So the big delay is somewhere within python.org. Since this does NOT happen to everyone, I would be looking for something like: * Moderation requirements (does your message not comply with spec?) * Spam greylisting * Slow/glitchy DNS when attempting to verify your message Most likely I think is moderation, given the extreme length of time. Something would have to be pretty glitchy to lag your mail out for half a day in spam filtering. It's possible, I guess, though. I've no idea what anti-spam features the list is using.

It's not just MUDs -- a lot of Internet protocols work that way. Netcat is one popular client for talking to/debugging/testing such servers. No doubt MUD clients too, but last time I did such stuff was in 1993, and I think I used telnet ... In fact, I'd design the protocol before starting to write code. Or better, steal some existing chat protocol. Like a subset of IRC. There's also another question in the original posting that bothers me: paraphrased "do I need to learn database programming to manage users"? No! Unix does fine with plain-text files. Managing credentials (understanding cryptography, setting up a support organization for resetting lost passwords ...) is non-trivial though, so try to do without such things at first.

No doubt MUD clients too, > but last time I did such stuff was in 1993, and I think I used telnet Yeah. As I mentioned, I'm a MUDder with tens of thousands of online hours on Threshold RPG[1], and have written several MUD clients; in fact, I'm right now working on Gypsum (fun fun). The most common internet protocols all: * Involve a well-known TCP port and a single socket connection (apart from FTP) * Begin with a one-line (usually) greeting from the server * Have a line-based request-and-response system * Have normal lines divided into "command" and "parameters" as per shell commands * (Usually) have an easy way to recognize success/failure, even without understanding the whole response * Are human-readable to the extreme * Rely on lower-level protocols for encryption (eg TLS) The mail trilogy (SMTP, POP, IMAP) are all like this, with the caveat that IMAP tags commands and responses (so the second word, not the first, is the command). FTP is almost there, apart from its secondary data channel. MUDs are definitely right there. And when I started putting together some networking facilities at work, I naturally gravitated to this kind of system. Even when it's a purely internal protocol, I like being able to just telnet/netcat to the service and operate everything manually. To date, I think I've implemented five or six such protocols within the suite at work, with only a couple of systems done differently (one of them uses a PHP client, for hysterical raisins, so it's done over HTTP). Plus, it's great to be able to break out the MUD client at work without getting in trouble for playing games on company time :) ChrisA [1] http://www.thresholdrpg.com/ if you'd like to join me!

Designing a Pythonic search DSL for SQL and NoSQL databases
Dear Python community, I am analysing designing an abstraction layer over a select few NoSQL and SQL databases. Specifically: - Redis, Neo4j, MongoDB, CouchDB - PostgreSQL Being inexperienced; it is hard to know a nice way of abstracting search. For conciseness in my explanation, think of `Table` as being table, object, entity or key; and `name` as being name or type. Maybe `res = Table.name.search()` Or on multiple `Table`: `res = AbstractDB().AbstractSearch( )` Then: `res.paginate(limit=25, offset=5)` Or if you want all: `res.all()` And additionally borrow/alias from a relevant subset of PEP249, e.g.: `fetchone` and `fetchmany` Will open-source this once it's of sufficient functionality. What do you think? Advice on better design; or just feedback on what I've mentioned? Thanks, Alec Taylor PS: I am using Bottle. You'll note that some of the syntax I've references is inspired from web2py's DAL and ODMG. -- http://mail.python.org/mailman/listinfo/python-list

Before you even begin to think about "how to do this in Python", you need to think about "how to do this at all". You've got a huge range of storage paradigms there. Redis is basically a key-value store. Mongo does documents. Postgres does relations. I'm not familiar with Neo and Couch, but I assume they also have their own interesting ways of storing things. You need to figure out what it means to abstract search over such a diverse range of technologies. I honestly don't think it's possible, but maybe you've got some good ideas. In any case, you need to figure that part out before you even begin to think about how to implement it in any particular language. -- http://mail.python.org/mailman/listinfo/python-list

In addition to all the various front-end filters running in the Postfix SMTP daemon (which trap most spam), SpamBayes is used as a last check to score messages intended for delivery to most mailing lists hosted on mail.python.org. It leaves two headers behind as proof of its existence. Here are those headers for Matthew's message that started this thread: X-Spam-Status: OK 0.017 X-Spam-Evidence: '*H*': 0.97; '*S*': 0.00; 'subject:Python': 0.06; 'problem?': 0.07; 'subject:posting': 0.09; 'python': 0.11; 'posted': 0.15; 'effect.': 0.16; 'missing?': 0.16; 'python-dev,': 0.16; 'server,': 0.19; 'all:': 0.24; "i've": 0.25; 'message- id:@mail.gmail.com': 0.30; 'obscure': 0.31; 'lists': 0.32; 'trouble': 0.34; 'anybody': 0.35; 'but': 0.35; 'received:google.com': 0.35; 'there': 0.35; 'subject:List': 0.36; 'list.': 0.37; 'gmail': 0.38; 'to:addr:python-list': 0.38; 'issue': 0.38; 'moving': 0.39; 'to:addr:python.org': 0.39; 'mailing': 0.39; 'first': 0.61; 'hours': 0.66 so SpamBayes thought it looked fine. Had it been marked as "UNSURE" or "SPAM" in the status header, Mailman would have held it for moderator attention. It is possible it was held by Mailman for some other reason. Some obvious reasons: sender isn't subscribed, message had too many recipients, python-list@python.org was BCC'd (implicit destination). If you message was held by Mailman, moderator overload is the most likely cause of the delay. It's also possible Mailman got overwhelmed, but I've seen no postmaster messages suggesting there were any systemic problems. BTW, although SpamBayes serves as a last resort for mail arriving via SMTP, it is the only line of defense for mail gatewayed from Usenet.

Share Code Tips
Aloha Python Users!
I have some coding tips and interesting functions that I want to share
with all of you. I want to give other programmers ideas and inspiration.
It is all Python3; most of it should work in Python2. I am a Unix/Linux
person, so some of these will only work on Unix systems. Sorry Microsuck
users :-D ;-)
All of the below Python3 code came from Neobot v0.8dev. I host an
artificial intelligence program on Launchpad (LP Username:
devyncjohnson-d). I have not released my Python version yet. The current
version of Neobot (v0.7a) is written in BASH and Python3.
To emulate the Linux shell's date command, use this Python
function def DATE(): print(time.strftime("%a %B %d %H:%M:%S %Z %Y"))
Want an easy way to clear the terminal screen? Then try this:
def clr(): os.system(['clear','cls'][os.name == 'nt'])
Here are two Linux-only functions:
def GETRAM(): print(linecache.getline('/proc/meminfo',
1).replace('MemTotal:', '').strip()) #Get Total RAM in kilobytes#
def KDE_VERSION(): print(subprocess.getoutput('kded4 --version | awk -F:
\'NR == 2 {print $2}\'').strip()) ##Get KDE version##
Need a case-insensitive if-statement? Check this out:
if 'YOUR_STRING'.lower() in SOMEVAR.lower():
Have a Python XML browser and want to add awesome tags? This code would
see if the code to be parsed contains chess tags. If so, then they are
replaced with chess symbols. I know, many people hate trolls, but trolls
are my best friends. Try this:
if 're.sub('', '♔', PTRNPRS, flags=re.I); DATA =
re.sub('', '♕', DATA, flags=re.I); DATA =
re.sub('', '♖', DATA, flags=re.I); DATA =
re.sub('', '♗', DATA, flags=re.I); DATA =
re.sub('', '♘', DATA, flags=re.I); DATA =
re.sub('', '♙', DATA, flags=re.I); DATA =
re.sub('', '♚', DATA, flags=re.I); DATA =
re.sub('', '♛', DATA, flags=re.I); DATA =
re.sub('', '♜', DATA, flags=re.I); DATA =
re.sub('', '♝', DATA, flags=re.I); DATA =
re.sub('', '♞', DATA, flags=re.I); PTRNPRS =
re.sub('', '♟', DATA, flags=re.I)
For those of you making scripts to be run in a terminal, try this for a
fancy terminal prompt:
INPUTTEMP = input('User ≻≻≻')
I may share more code later. Tell me what you think of my coding style
and tips.

Aloha Python programmers!
I am making a chatbot that I host on Launchpad.net/neobot. I am
currently converting the engine from BASH code to Python3. I need to
convert this for cross-platform compatibility. I do not need to use
Mplayer; I just show the below code to give others a better idea what I
am doing. I would prefer to be Python3 independent; I do not want to use
the system shell. I am fine with using Python3 modules like Pygame (if
there is a py3 module). As long as the code is fast, efficient, and
simple without depending on the system shell or external apps, that
would be nice. I also need the code to execute while the rest of the
script continues running.

Re: Messages to Python-List aren't posting
(Sorry to reply-all, but in this case I think the direct messages will get to people on this thread 12 hours earlier than the others.) Well, I have had this problem with both my work email (matthew dot lefavor _at_ nasa dpt gov) and my Gmail account. Since this doesn't happen to all users (nor all Gmail users, for that matter), the only thing that's constant here is that it's my name (well, and my password, but one would hope that passwords aren't relevant here). Is it possible that the name "Matthew Lefavor" has been added to a greylist or something? One relevant piece of information: I have subscribed and unsubscribed to different combinations of these lists several times over the past year, and particularly over the past few months (as I was trying to manage the flow of emails to my filter-less work inbox.) Could that sort of behavior associate my name with malicious intent?

Re: Designing a Pythonic search DSL for SQL and NoSQL databases
Hmm, looking at the capabilities of Redis; you're likely right. Would welcome discussion on the implementability and usefulness of a central search abstraction to the other stores mentioned. One thing could be that using the paradigm the database was made for is better than any advantages abstracting their differences creates.

I don't think you intended to put DATA in quotes on the right hand side.
That makes it literally the string D A T A, so all those replacements are
no-ops, and you could simplify it to:
DATA = 'DATA'
But that's probably not what you wanted.
My prediction is that this will be by far the most efficient way to do
what you are trying to do:
py> DATA = "Hello, 'World'()"
py> DATA.translate(dict.fromkeys(ord(c) for c in ",'()"))
'Hello World'
That's in Python 3 -- in Python 2, using translate will still probably be
the fastest, but you'll need to call it like this:
import string
DATA.translate(string.maketrans("", ""), ",'()")
I also expect that the string replace() method will be second fastest,
and re.sub will be the slowest, by a very long way.
As a general rule, you should avoiding using regexes unless the text you
are searching for actually contains a regular expression of some kind. If
it's merely a literal character or substring, standard string methods
will probably be faster.
Oh, and a tip for you:
- don't escape quotes unless you don't need to, use the other quote.

Greylisting is great, but there are a couple of quirks, as the company I work for discovered the hard way. Some ISPs don't follow the rules. I'm not talking about dinky little ISPs run by some guy in a basement, I'm talking some of the biggest ISPs in Australia like Optus or Bigpond. They either completely ignore the "try later" message, and report it as a hard failure, or they wait a full day before trying again instead of a few minutes. Or, if they do try again, they try again from a different mail server, so the greylisting software sees a different sender/server combination, and greylists that as well. Admittedly, this was a few years back that we ran into this problem, and since then we've just routinely whitelisted email from Optus and Bigpond, curse their black souls for making spam prevention just that little bit harder. So I suppose it's possible that they've stopped being bad actors and started following the standards correctly.

By the way, a comment that doesn't tell you anything that you don't

Case-insensitivity is very hard. Take German for example:
STRASSE <-> straße
Or Turkish:
İ <-> i
I <-> ı
In Python 3.3, you should use casefold rather than lowercase or uppercase:
if some_string.casefold() in another_string.casefold(): ...
but even that can't always take into account localised rules, e.g. in
German, you should not convert SS to ß for placenames or person names, so
for example Herr Meißner and Herr Meissner are two different people. This
is one of the motivating reasons for introducing the uppercase ß.

This Flexible String Representation is a dream case study.
Attempting to optimize a subset of character is a non sense.
If you are a non-ascii user, such a mechanism is irrelevant,
because per definition you do not need it. Not only it useless,
it is penalizing, just by the fact of its existence. [*]
Conversely (or identically), if you are an ascii user, same situation,
it is irrelevant, useless and penalizing.
Practically, and today, all coding schemes we have
(including the endorsed Unicode utf transformers) work
with a unique set of of encoded code points. If you
wish to take the problem from the other side, it is
because one can only work properly with a unique set
of code points that so many coding schemes exist!
Question: does this FSR use internally three coding
schemes because it splits Unicode in three groups or
does it split Unicode in three subsets to have the joyce
to use three coding schemes?
About "micro benchmarks". What to say, they appear
practivally every time you use non ascii.
And do not forget memory. The €uro just become expensive.
>>> sys.getsizeof('$')
26
>>> sys.getsizeof('€')
40
I do not know. When an €uro char need 14 bytes more that
a dollar, I belong to those who thing there is a problem
somewhere.
This FSR is a royal gift for those who wish to teach Unicode
and the coding of characters.

Don't fool yourself that you can do it with a simple line of code and have it 'just work'. All you'll have is something that works "most of the time", and then breaks on certain input. As Steven said, using casefold() rather than lower() will help, but that's still not perfect. The simplest and safest way to solve Unicode capitalization issues is to declare that your protocol is case sensitive. I have a brother who couldn't understand why Unix file systems have to be case sensitive (why would anyone ever want to have "readme" and "README" in the same directory, after all?), until I explained how majorly hard it is with i18n, and how it suddenly becomes extremely unsafe for your *file system* to get this wrong.

Thanks for finding that error; DATA should not be in quotes. I cannot
believe I missed that. Good eye Steven!
Using the replace command is a brilliant idea; I will implement that
where ever I can. I am wanting to perform all of the replaces at once.
Is that possible?
Read what you're quoting from. The translate() method does just that.
And maketrans() is the way to build a translate table.
On an Intel processor, the xlat instruction does a translate for one
character, and adding a REP in front of it does it for an entire buffer.
No idea if Python takes advantage of that, however.

Python testing tools
I am currently doing some research on testing software for Python. I found that there are many different types of testing tools. These are what I've found. 1.Unit test 2.Mock test 3.Fuzz test 4.Web test 5.Acceptance/business logic test 6.GUI test 7.Source code checking 8.Code coverage 9.Continuous integration 10.Automatic test runners 11.Test fixtures I know web and GUI testing tools are for specific uses. For instance, if you are not working with GUI or web pages, you don't need those testing tools. Other than these two, do you use all of the other nine testing tools? I think many of you are using unit testing tools, such as unittest and doctest, and source code checking tools, like pylint or pychecker. Do you guys use #2,3,5,8,9,10 and 11 often?

how: embed + extend to control my running app?
i'd like my app to be "available" to python while it's running. for example, say my app is "FooBar.app". when my FooBar.app is running, now there is a python interface available to python, and the user can write python scripts to make use of it. with their scripts, they can control my running application when FooBar.app is NOT running, perhaps making use of any of the python functions of "FooBar.app" would either return an error, or possibly launch "FooBar.app"? or do nothing since it's not running? can boost::python help with this? i've never worked with extending or embedding python, so any help would be super great -- http://mail.python.org/mailman/listinfo/python-list

Well, casefold is about as good as it's ever going to be, but that's because "the perfect international-case-insensitive comparison" is a fundamentally impossible goal. Your last sentence hints as to why; there is no simple way to compare strings containing those characters, because the correct treatment varies according to context. Your two best options are: Be case sensitive (and then you need only worry about composition and combining characters and all those nightmares - the ones you have to worry about either way), or use casefold(). Of those, I prefer the first, because it's safer; the second is also a good option. ChrisA -- http://mail.python.org/mailman/listinfo/python-list

Interfacing C and Python like you suggest can't be done with embedding, because that requires that your app be already running, and probably not by having your code run as a pure module. In fact, I would actually suggest that you devise a separate protocol between your app and the Python script, and run them as separate processes. That way, they run independently, and you may (platform-specific code required here though) be able to invoke your app; most importantly, you'll be able to cleanly handle multiple Python scripts trying to control you simultaneously. What platforms are you aiming at? If it's just for Unix-like ones, the easiest way is probably to create a Unix domain socket, which the Python program can write to and/or read from. With a protocol based around simple operations like that, your Python module need not even involve C code - it simply opens a socket file and uses standard I/O methods on it. Alternatively, you may want to consider a TCP socket, which would let you split the client and server across a network, or possibly direct shared memory access. The world's your oyster.

Sure, the casefold() method has its problems. But you're going to avoid using it till you can do a "perfect" one? Perfect in what context? For "case sensitively" comparing people's names in a single language in a single country? Perhaps that can be made perfect. For certain combinations of language and country. But if you want to compare words in an unspecified language with an unspecified country, it cannot be done. If you've got a particular goal in mind, great. But as a library function, you're better off using the best standard method available, and document what its limitations are. One way of documenting such is to quote the appropriate standards, with their caveats. By the way, you mentioned earlier that you're restricting yourself to Latin characters.

As I showed, even for Latin letters, the trick of "if astring.lower() == bstring.lower()" doesn't *quite* work, although it can be "close enough" for some purposes. For example, some languages treat accents as mere guides to pronunciation, so ö == o, while other languages treat them as completely different letters. Same with ligatures: in modern English, æ should be treated as equal to ae, but in Old English, Danish, Norwegian and Icelandic it is a distinct letter. Case-insensitive testing may be easier in many non-European languages, because they don't have cases. A full solution to the problem of localized string matching requires expert knowledge for each language, but a 90% solution is pretty simple: astring.casefold() == bstring.casefold() or before version 3.3, just use lowercase. It's not a perfect solution, but it works reasonably well if you don't care about full localization. -- Steven -- http://mail.python.org/mailman/listinfo/python-list

There are hundreds of written languages in the world, with thousands of characters, and most of them have rules about case-sensitivity and character normalization. For example, in Greek, lowercase Σ is σ except at the end of a word, when it is ς. ≻≻≻ 'Σσς'.upper() 'ΣΣΣ' ≻≻≻ 'Σσς'.lower() 'σσς' ≻≻≻ 'Σσς'.casefold() 'σσσ' So in this case, casefold() correctly solves the problem, provided you are comparing modern Greek text. But if you're comparing text in some other language which merely happens to use Greek letters, but doesn't have the same rules about letter sigma, then it will be inappropriate. So you cannot write a single "perfect" case-insensitive comparison, the best you can hope for is to write dozens or hundreds of separate case- insensitive comparisons, one for each language or family of languages.

Re: Play Ogg Files
you could use , and I think its
david@david:~$ python
Python 2.7.3 (default, Aug 1 2012, 05:16:07)
[GCC 4.6.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import subprocess
>>> subprocess.call(['espeak', 'word_spoken'], stdin=None, stdout=None,
stderr=None, shell=False)

Re: Play Ogg Files
This is using 3.2, which shouldn't be far off, the latest I could get on
ubuntu.
david@david:~$ python3.2
Python 3.2.3 (default, Apr 10 2013, 05:29:11)
[GCC 4.6.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.

stderr=None, shell=False)
