GOZERBOT 0.99.0 RELEASED
Hello world and everybody ! i'm pleased to announce the release of GOZERBOT 0.99.0, the first in a series of releases that are supposed to lead to a proper 1.0 release for GOZERBOT. The intention is to get a 1.0 version of GOZERBOT available for users that still use this bot, got almost 2000 download of 0.9.2 so its worth to support all those users with a release they can build on. I dont have the intention to develop GOZERBOT any further beyond that, that's what JSONBOT is all about, so keep in mind these are pure maintenance releases. 2 major changes crept into this release, namely: * no more seperate gozerplugs package, its all wrapped into 1 thing. The gozerplugs package has find its way under the gplugs directory in the main distro so no more seperate installing of plugins. * SQLAlchemy is now optional, so GOZERBOT can run on older versions of debian etc. Since this leads to less dependancies GOZERBOT is easier to install. note: there is not going to be a seperate all distro as those dependancies are already included. SQLAlchemy is made optional by providing plugins that use direct queries on the database, this is the default. You can change operations back to SA by setting db_driver = alchemy in gozerdata/ mainconfig. The intention is to release a new version of GOZERBOT every week or so, until its stable for a long period of time. When its time i'll cut of the 1.0 release ;] urls: * download tar - http://code.google.com/p/gozerbot/downloads/list * mercurial clone - hg clone https://gozerbot.googlecode.com/hg mybot * please report bugs at http://code.google.com/p/gozerbot/issues/entry especially if you are already running a GOZERBOT and run into problems. * path to the futire - http://jsonbot.org read the provided README for instructions on how to get the bot running. About GOZERBOT: GOZERBOT is a channel bot supporting conversations in irc channels and jabber conference rooms. It is mainly used to send notifications (RSS, nagios, etc.) and to have custom commands made for the channel. More then just a channel bot GOZERBOT aims to provide a platform for the user to program his own bot and make it into something thats usefull. This is done with a plugin structure that makes it easy to program your own plugins. GOZERBOT comes with some batteries included. -- http://mail.python.org/mailman/listinfo/python-announce-list Support the Python Software Foundation: http://www.python.org/psf/donations/

socket.getsockname is returning junk!!

I am migrating my application from python 1.5.2 to 2.7.1. One of the existing

Hi!
The problem may be that root user is disabled. This was introduced in
Ubuntu long ago and I believe that later this was also accepted in
Fedora. That means that you simply can not su to root, no matter
what password you supply. This is the way how your OS operates and is
not connected in any way to python or pexpect. Therefore, either use
sudo (generally recommended) or enable root user (insecure!).

Convenient filtering in for cycles
Dear all, I would like to know if there is a (more) convenient way of doing this structure: ===(1)=== for x in l: if P(x): do_stuff(x) == Let's say that my dream syntax would be ===(2)=== for x in l if P(x): do_stuff(x) == as if it was the second part of a list comprehension. But sadly it is not in the language. Obvious alternatives are ===(3)=== for x in (x for x in l if P(x)): do_stuff(x) == ===(4)=== for x in l: if not P(x): continue do_stuff(x) == ===(5)=== [do_stuff(x) for x in l if P(x)] == As I see it, every syntax-valid solution has its drawbacks: (1) adds an indentation level; (3) adds an unnatural repetition of variable names and for; (4) has the masked goto continue (even if it is quite easy to understand what happens); (5) is good but not usable when do_stuff is what it usually is, that is a list of instructions. Is there some better and valid construction I missed? If not, is there a reason why (2) is not in the language? Pardon my boldness, but I am asking this because there are two invalid construct that I keep writing when I don't pay attention: one is (2), and the other is list comprehensions as in ===(6)=== for x in (x in l if P(x)): do_stuff(x) == which accidentally would be a better solution than (1), (3), (4), (5), though not as good as (2).

Also, see these older threads: http://groups.google.com/group/comp.lang.python/browse_thread/thread/ef807313aa47efc/4f4269a7b566cb87 http://groups.google.com/group/python-ideas/browse_thread/thread/87eee156ac2c3a24/61621e7779b5b255 http://groups.google.com/group/python-ideas/browse_thread/thread/e2d076fe35ece873/862674672b4de683 Cheers, Ian -- http://mail.python.org/mailman/listinfo/python-list
Re: Convenient filtering in for cycles
Dear Ian, thank you for you kind response. I was pretty confident the issue had already been discussed, but I was unable to look it up. I suppose your filter syntax is the best given the options (I always forget about map and filter...) and definitely I see that the work needed to add such a feature is hardly worth the convenience. Still, I think it is sad that generators/list comprehensions and for cycles do not share the same syntax. Unfortunately, this example from one of your links convinces that anyway it is too late: (x for x in (l1 if c else l2)) # valid (x for x in l1 if c else l2) # SyntaxError for x in l1 if c else l2 # valid Cheers, Stefano -- http://mail.python.org/mailman/listinfo/python-list

encoding problem with BeautifulSoup - problem when writing parsed text to file
Hi, I am having some encoding problems when I first parse stuff from a non-english website using BeautifulSoup and then write the results to a txt file. I have the text both as a normal (text) and as a unicode string (utext): print repr(text) 'Branie zak\xc2\xb3adnik\xc3\xb3w' print repr(utext) u'Branie zak\xb3adnik\xf3w' print text or print utext (fileSoup.prettify() also shows 'wrong' symbols): Branie zak³adników Now I am trying to save this to a file but I never get the encoding right. Here is what I tried (+ lot's of different things with encode, decode...): outFile=open(filePath,w) outFile.write(text) outFile.close() outFile=codecs.open( filePath, w, UTF8 ) outFile.write(utext) outFile.close() Thanks!! -- http://mail.python.org/mailman/listinfo/python-list

It's simple, obvious and readable. Let's say that my dream syntax would be ===(2)=== for x in l if P(x): do_stuff(x) == That is exactly the same as #1 above, except it takes one extra line (trivial) and one extra indent level (almost always trivial). So what's the problem with #1? If you have so many indent levels that one more level causes you grief, then consider that Nature's way of telling you that you have too much code in one chunk and that you should refactor some of it into functions. as if it was the second part of a list comprehension. But sadly it is not in the language. Obvious alternatives are ===(3)=== for x in (x for x in l if P(x)): do_stuff(x) == A hard to read mess. Best avoided. ===(4)=== for x in l: if not P(x): continue do_stuff(x) == Saves an indent level, otherwise virtually identical to #1. ===(5)=== [do_stuff(x) for x in l if P(x)] == Only appropriate if you care about the return results of do_stuff. If you are using a list comprehension solely for the side-effects, don't. As I see it, every syntax-valid solution has its drawbacks: (1) adds an indentation level; This shouldn't be a drawback. This should be an advantage. It's an extra indentation level because it represents a block of code. (3) adds an unnatural repetition of variable names and for; (4) has the masked goto continue (even if it is quite easy to understand what happens); While it is true that goto is harmful, it is possible to take the hatred of goto to ridiculous levels. Calling a function is a masked goto. For-loops and while loops are masked gotos. That doesn't make them bad things. There is nothing inherently wrong with continue and break for flow control, although of course you can write bad code with any construct. (5) is good but not usable when do_stuff is what it usually is, that is a list of instructions. Is there some better and valid construction I missed? If not, is there a reason why (2) is not in the language? Because it complicates the language for very little benefit. That makes the language harder to learn and read and the compiler harder to maintain.

[issue13045] socket.getsockopt may require custom buffer contents
Charles-François Natali neolo...@free.fr added the comment: I've attached an update for the previous patch. Now there's no more overloading for the third argument and socket.getsockopt accepts one more optional argument -- a buffer to use as an input to kernel. Remarks: + length. If *buffer* is absent and *buflen* is an integer, then *buflen* [...] + this buffer is returned as a bytes object. If *buflen* is absent, an integer There's a problem here, the first buflen part should probably be removed. Also, you might want to specify that if a custom buffer is provided, the length argument will be ignored. By the way, I don't really think that any POSIX-compliant UNIX out there would treat the buffer given to getsockopt in any way different from what Linux does. It is very easy to copy the buffer from user to kernel and back, and it is so inconvenient to prevent kernel from reading it prior to modification, that I bet no one has ever bothered to do this. Me neither, I don't expect the syscall to return EINVAL: the goal is just to test the correct passing of the input buffer, and the length computation. If we can't test this easily within test_socket, it's ok, I guess the following should be enough: - try supplying a non-buffer argument as fourth parameter (e.g. and int), and check that you get a ValueError - supply a buffer with a size == sizeof(int) (SIZEOF_INT is defined in Lib/test/test_socket.py), and call getsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 0, buffer): this should normally succeed, and return a buffer (check the return type) -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue13045 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

This is right.
I think I prefer the new behavior...
The patch looks good, I would simply have raised AttributeError(name)
though.
It is fine with me to raise AttributeError(name).
Note that when raising AttributeError('socket'), the user gets
notified of the exceptions on both 'socket' and 'name'.

[issue13112] backreferences in comprehensions
New submission from yoch yoch.me...@gmail.com:
Hi,
I would like to use backreferences in list comprehensions (or other
comprehensions), such as :
[[elt for elt in lst if elt] for lst in matrix if \{1}]
# \{1} is back reference to [elt for elt in lst if elt]
# to filter the result of the first comprehension
It would be possible to do this ?
Thanks
