GOZERBOT 0.9.2 BETA1 released
I just released the first BETA of GOZERBOT version 0.9.2 Please test this release if you can. Best is to run of the mercurial repo: hg clone http://core.gozerbot.org/hg/dev/0.9 or run easy_install -U gozerbot gozerplugs (make sure there is no gozerbot dir in your working directory.) docs are at http://gozerbot.org/0.9.2 If you find any bugs you can report them at http://dev,gozerbot.org/ Have fun ! about GOZERBOT: GOZERBOT is a channel bot that aids with conversation in irc channels and jabber conference rooms. its 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. But GOZERBOT comes with some batteries included, there are now over 100 plugins already written and ready for use. -- http://mail.python.org/mailman/listinfo/python-announce-list Support the Python Software Foundation: http://www.python.org/psf/donations/

The first crash case was happening in calling python-xml module, which is claimed as a pure python module, and it's not supposed to crash python interpreter. because the python application is relatively a big one, I can not show u guys the exact source code related with the crash, but only the piece of python modules. GDB shows it's crashed at string join operation: #0 string_join (self=0x7f7075baf030, orig=value optimized out) at ../Objects/stringobject.c:1795 1795../Objects/stringobject.c: No such file or directory. in ../Objects/stringobject.c and pystack macro shows the details: gdb) pystack /usr/lib/python2.5/StringIO.py (271): getvalue /usr/lib/python2.5/site-packages/_xmlplus/dom/minidom.py (62): toprettyxml /usr/lib/python2.5/site-packages/_xmlplus/dom/minidom.py (47): toxml at that time, we also found python-xml module has performance issue for our application, so we decided to use python-lxml to replace python-xml. After that replacement, the crash was gone. That's a bit weird for me, but anyway, it's gone. Unfortunately, another two 'kinds' of crashes happening after that, and the core dumps show they are not related with the replacement. One is crashed with Program terminated with signal 11, and the pystack macro shows it's crashed at calling the built-in id() function. #0 visit_decref (op=0x20200a3e22726574, data=0x0) at ../Modules/ gcmodule.c:270 270 ../Modules/gcmodule.c: No such file or directory. in ../Modules/gcmodule.c Another is crashed with Program terminated with signal 7, and the pystack macro shows it's crashed at the exactly same operation (string join) as the first one (python-xml), but in different library python- simplejson: #0 string_join (self=0x7f5149877030, orig=value optimized out) at ../Objects/stringobject.c:1795 1795../Objects/stringobject.c: No such file or directory. in ../Objects/stringobject.c (gdb) pystack /var/lib/python-support/python2.5/simplejson/encoder.py (367): encode /var/lib/python-support/python2.5/simplejson/__init__.py (243): dumps I'm not good at using gdb C programming, then I tried some other ways to dig further: * get the source code of python2.5, but can not figure out the crash reason :( * since Debian distribution provides python-dbg package, and I tried to use python2.5-dbg interpreter, but not the python2.5, so that I can get more debug information in the core dump file. Unfortunately, my python application is using a bunch of C modules, and not all of them provides -dbg package in Debian/Lenny. So it still doesn't make any progress yet. I will be really appreciated if somebody can help me about how to debug the python crashes. For me, it sounds like a hardware problem. Have run memory tests like memtest86+ and/or memtester? You could try a more recent version of Python like 2.6.5 and see if you get the same sort of errors. Try to run your application on a different machine if possible, to exclude hardware errors. Have you rebuild all Python packages you're using and which use an extension in C / C++ ? after upgrading?

Apparently either you and the General Decimal Arithmetic spec differ on what constitutes engineering notation, there's a bug in the Python decimal library, or you're hitting some obscure part of the spec's definition. I don't have the expertise to know which is the case. The spec: http://speleotrove.com/decimal/decarith.pdf (to-engineering-string is on page 20 if you're interested) The module is correct. Printing without exponent follows the same rules as to-scientific-string: If the exponent is less than or equal to zero and the adjusted exponent is greater than or equal to -6, the number will be converted to a character form without using exponential notation.

That is not an engineering notation string.
To clarify further: The spec says that the printing functions are not
context sensitive, so to_eng_string does not *apply* the context.
The context is only passed in for the 'capitals' value, which determines
whether the exponent letter is printed in lower or upper case.
This is one of the unfortunate situations where passing a context can
create great confusion for the user. Another one is:
c = Context(prec=5)
Decimal(12345678, c)
Decimal('12345678')
Here the context is passed only for the 'flags' and 'traps' members:
Decimal(wrong, c)

But its limitation is that when c++module is called in python script it doent take me into c++ module.

In other words, I want to follow my program line by line. Please guide me. Thank you. Regards, Sanam Hi Sanam, The usual way to work that way is having one of the debuggers work in remote debug mode (so, if you launch it from a python ide, the c++ remote debugger should connect to it remotely, or if you launch it from the c++ ide, the python debugger should connect to it remotely).

Re: how to select column
It depends on what you mean by a column. I assume your data is more
complex than what you've shown us.
If your data is really single words separated by spaces, you can do:
for line in open('file'):
columns = line.split()
return columns[0], columns[3]
If your columns can have spaces within them, or are separated in other
ways, you'll need something else.

[ANN]: 'tren' Cross-Platform Batch Renaming Tool, Version 1.217 Released
'tren' Version 1.217 is now released and available for download at: http://www.tundraware.com/Software/tren - What's New In This Release? --- This is the initial public release. What Is 'tren'? -- 'tren' is a general purpose file and directory renaming tool. Unlike commands like 'mv', 'tren' is particularly well suited for renaming *batches* of files and/or directories with a single command line invocation. 'tren' eliminates the tedium of having to script simpler tools to provide higher-level renaming capabilities. 'tren' is also adept at renaming only *part of an existing file or directory name* either based on a literal string or a regular expression pattern. You can replace any single, group, or all instances of a given string in a file or directory name. 'tren' implements the idea of a *renaming token*. These are special names you can embed in your renaming requests that represent things like the file's original name, its length, date of creation, and so on. There are even renaming tokens that will substitute the content of any environment variable or the results of running a program from a shell back into the new file name. 'tren' can automatically generate *sequences* of file names based on their dates, lengths, times within a given date, and so on. In fact, sequences can be generated on the basis of any of the file's 'stat' information. Sequence numbers can be ascending or descending and the count can start at any initial value. Counting can take place in one of several internally defined counting alphabets (decimal, hex, octal, alpha, etc.) OR you can define your own counting alphabet. This allows you to create sequences in any base (2 or higher please :) using any symbol set for the count. 'tren' is written in pure Python and requires Python version 2.6.x or later. It is known to run on various Unix-like variants (FreeBSD, Linux, MacOS X) as well as Windows. It will also take advantage of 'win32all' Python extensions on a Windows system, if they are present. - Complete details of all fixes, changes, and new features can be found in the WHATSNEW.txt and documentation files included in the distribution. A FreeBSD port has been submitted as well. -- http://mail.python.org/mailman/listinfo/python-list

Some objects missing from tkinter
I'm new to Python, so I'll try to be clear about my problem. I'm using Python 3.1 (latest stable version from python.org) on Windows 7. I have a program using tkinter for UI, and it works properly from both pything GUI shell, and running from command prompt, EXCEPT that I have a menu command to invoke tkinter.filedialog.askopenfile, and it fails because it says: file = tkinter.filedialog.askopenfilename() AttributeError: 'module' object has no attribute 'filedialog' I made a simple test program: import tkinter print (dir(tkinter)) when I run this from the GUI shell, the results include filedialog, but from the command prompt, it does not (also missing other attributes, such as messagebox). All the UI widgets work properly. My best hypothesis at this point is that from the GUI shell its using the source code under lib\tkinter (where there is a filedialog.py), but from the command shell it is using the compiled dll, and that doesn't export filedialog for some reason.

It's not that complicated; idle and your module share the same python interpreter and the same tkinter package. Idle needs a file dialog, too, and somewhere in its code there must be a import tkinter.filedialog statement which of course isn't executed when you run your script from the command line. To fix your script simply add the above import statement. It is a bit unfortunate that your editor has side effects on your program, and I recommend that you never trust the result of importing a module from within idle's shell completely.

On Apr 26, 8:44 am, lkcl luke.leigh...@googlemail.com wrote: the purpose of browsers is to isolate the application, restrict its access to the rest of the desktop and OS, so that random applications cannot go digging around on your private data. Well, I would agree that a requirement for the browser is to help insure the user's safety, but would argue that the *purpose* is somewhat more functional than that :-) many browsers _used_ to allow access to local files etc. but ... yeah. I know. But, with most browsers, you can say yes, I know I'm downloading this Java program. I know it can have its way with my hard drive. Trust me; I know what I'm doing here. Same thing with Adobe or Microsoft stuff: silverlight, AIR, flash, PDFs. Basically, the browser delegates ALL security control at that point. I just think it would be nice if the browser could delegate a _little_ security control to the user (allow this JavaScript program to read/write arbitrary files in this directory; possibly with a total file size limitation) for programs that can run inside the browser. so i think you will be able to do what you describe _if_ you provide a browser plugin which adds the required functionality. Agreed. Alternatively, of course, you could have code to let the user download to a local file from the application's local storage area for backup purposes, but that seems suboptimal. google gears would be a good place to start (i've part-ported GWT Gears to pyjamas - the SQL storage modules - to demonstrate what's needed). I think even gears assumes a database under the browser's control; not an arbitrary node in the filesystem. Also, I think gears is no longer being developed. Of course, gears could be OK as a starting point, but really what you are saying is that everybody wanting to use this new file local storage feature would need an add-on. I agree that's probable, but in that case it's only really worth doing if a lot of projects would use it. I'm not sure if that will come to pass or not -- it would need a lot of programmers to think that it was a great thing. OTOH, if a particular browser supported this functionality natively, then it might be a competitive advantage if applications did develop to support it. if however you completely ignore browsers from the equation, by virtue of having to piss about writing c code, then yes, you can use pyjamas-desktop. at that point, you have _full_ access to the entire OS and system, because you're firing up the web browser engine as a python application. That's understood (and a great thing). But if programmers could use pyjamas in the browser without an extra download to get to all the desktop features (which is how it *appears* to most users when they use flash or something like that), that would be a great win. Alternatively, a single small download of a broswer add-on package to bring pyjamas desktop features into the browser (maybe even just for mozilla for now) would be awesome, as well.

Well, I would agree that a requirement for the browser is to help insure the user's safety, but would argue that the *purpose* is somewhat more functional than that :-) we know :) many browsers _used_ to allow access to local files etc. but ... yeah. I know. But, with most browsers, you can say yes, I know I'm downloading this Java program. ... which requires a java plugin I know it can have its way with my hard drive. Trust me; I know what I'm doing here. Same thing with Adobe or Microsoft stuff: silverlight, plugin AIR, aka webkit (modified) plus plugins flash, plugin PDFs. often done as a plugin (e.g. mozplugger for firefox) Basically, the browser delegates ALL security control at that point. I just think it would be nice if the browser could delegate a _little_ security control to the user (allow this JavaScript program to read/write arbitrary files in this directory; possibly with a total file size limitation) for programs that can run inside the browser. on IE, this is already possible - without needing plugins. active scripting. however, it requires security settings that people simply aren't equipped to correctly modify. so i think you will be able to do what you describe _if_ you provide a browser plugin which adds the required functionality. Agreed. Alternatively, of course, you could have code to let the user download to a local file from the application's local storage area for backup purposes, but that seems suboptimal. google gears would be a good place to start (i've part-ported GWT Gears topyjamas- the SQL storage modules - to demonstrate what's needed). I think even gears assumes a database under the browser's control; not an arbitrary node in the filesystem. Also, I think gears is no longer being developed. Of course, gears could be OK as a starting point, but really what you are saying is that everybody wanting to use this new file local storage feature would need an add-on. I agree that's probable, but in that case it's only really worth doing if a lot of projects would use it. preeeciselyyy. which is why nobody does it. and, given that you can use AJAX (e.g. JSONRPC) to communicate with a server-side component, installed on 127.0.0.1 and effectively do the exact same thing, nobody bothers. the JSONRPC stuff is pretty trivial (if annoying by the fact that it's asynchronous function calls, client-side) - and there are half a dozen server-side implementations. the ones we recommend people use with pyjamas are actually damn good: decorators turn an ordinary function into a JSONRPC service with a single import and a single line of code (decorator) per function. that's _it_. the actual implementation, aside from apt-get install simplejson is about _thirty_ lines of code (incredibly) for joining up JSONRPC to django or web2py etc. etc. it's so small an amount of code that the django developers are refusing to include it in the standard distribution, because it doesn't look scarily complicated enough, doesn't make programming with JSONRPC difficult enough for them, and generally makes life too easy. i love it when programmers get scared by code that appears to be too easy and not stressful enough to be acceptable, because then they stay away from me, thank goodness. but - yeah: JSONRPC's definitely your most sensible pragmatic option. server-side you can then do absolutely anything. if you use pyjs, you then have the advantage that the application will still work as pure python under pyjd _even_ though it uses HTTPRequest, because i made damn sure that the XmlHTTPRequest objects which you _expect_ to use javascript-only _still_ work even under the three ports (pywebkitgtk, xulrunner and MSHTML). (that was fun-and-games and there's still massive repercussions with the fucking crack-heads from the webkit team over the access to XmlHTTPRequest from glib/gobject... just don't ask for details... ) if however you completely ignore browsers from the equation, by virtue of having to piss about writing c code, then yes, you can use pyjamas-desktop. at that point, you have _full_ access to the entire OS and system, because you're firing up the web browser engine as a python application. That's understood (and a great thing). But if programmers could usepyjamas in the browser without an extra download to get to all the desktop features (which is how it *appears* to most users when they use flash or something like that), no - it's not going to happen: it's _required_ to install the flash plugin. that would be a great win. yes. if you can tolerate the plugin

Re: Engineering numerical format PEP discussion
Apparently either you and the General Decimal Arithmetic spec differ on what constitutes engineering notation, there's a bug in the Python decimal library, You've distilled it precisely, and as you've shown in a different post, it's the former. The Python decimal module seems to implement correctly Mike Cowlishaw's spec, but what that spec refers to as engineering notation isn't really what engineers actually use. That is, even with decimal.Decimal.to_eng_string(), engineers still end up having to write their own string formatting code. I think it's worth making the print statement (or print function, as the case may be) let us do engineering notation, just like it lets us specify scientific notation. --Keith Brafford -- http://mail.python.org/mailman/listinfo/python-list

The context is only passed in for the 'capitals' value, which determines

This is one of the unfortunate situations where passing a context can
create great confusion for the user. Another one is:
c = Context(prec=5)

[issue8493] socket's send can raise errno 35 under OS X, which causes problems in sendall
Charles-Francois Natali neolo...@free.fr added the comment: That's what I thought at first too. But the user's sockets were set to blocking. That's one broken networking stack... In fact, I think it's a little silly that OS X raises the error rather than just saying that 0 bytes were sent (which is what I suppose that other OSes do). Normal OS just block inside the send() call whenever socket buffers are full (unless there're set to non-blocking). So you can resume sending as soon as buffer space is available, and you don't have to resort to this send()/fail/sleep/re-send() scheme... But I think it's also not ideal that Python's socket.sendall() can't be used with confidence under OS X because it can fail under pretty normal circumstances. Agreed, but it's really a OS X issue here. How would you circumvent this problem anyway ? Add a timeout option to sendall() as a hint to how much we should wait before retrying when errno 35 is returned ? It would be really hacky... Maybe the user could try increasing SO_SNDBUF, but this won't necessarily solve his problem... @exarkun: ideas on this ? -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue8493 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue7946] Convoy effect with I/O bound threads and New GIL
Antoine Pitrou pit...@free.fr added the comment: Dave, In the current implementation, threads perform a timed-wait on a condition variable. If time expires and no thread switches have occurred, the currently running thread is forced to drop the GIL. A problem, as far as I can see, is that these timeout sleeps run periodically, regardless of the actual times at which thread switching takes place. I'm not sure it's really an issue but it's a bit of a departure from the ideal behaviour of the switching interval. A new attribute 'cpu_bound' is added to the PyThreadState structure. If a thread is ever forced to drop the GIL, this attribute is simply set True (1). If a thread gives up the GIL voluntarily, it is set back to False (0). This attribute is used to set up simple scheduling (described next). Ok, so it's not very different, at least in principle, from what gilinter.patch does, right? (and actually, the benchmark results look very similar) -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue7946 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Antoine Pitrou pit...@free.fr added the comment: That's what I thought at first too. But the user's sockets were set to blocking. If you set a timeout on a socket, it is really non-blocking internally (from the OS' point of view). So perhaps this is what you are witnessing. By the way, rather than sleeping a fixed amount of time before retrying, you could probably use select() on the socket. -- nosy: +pitrou ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue8493 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

This is useful only when BaseHTTPServer is started in the command like as a standalone HTTP server. What shall we do for this? remove the fqdn or cache it once and use it. Either is fine.

[issue8514] Create fsencode() and fsdecode() functions in os.path
STINNER Victor victor.stin...@haypocalc.com added the comment: They're also useful for dealing with environment variables which are not strictly filesystem (fs) related but also suffer from the same issue requiring surrogate escape. Yes, Python3 decodes environment variables using sys.getfilesystemencoding()+surrogateescape. And since my last fix on os.execve(), subprocess (and os.execv(p)e) uses also surrogateescape to encode environment variables. And yes again, I also patched os.getenv() to decode bytes name to unicode using sys.getfilesystemencoding()+surrogateescape. But other than just calling these os.encode and os.decode *fs*encode() and *fs*decode() is a reference to the encoding: sys.get*filesystem*encoding().

[issue8533] regrtest: use backslashreplace error handler for stdout
New submission from STINNER Victor victor.stin...@haypocalc.com: If a test fails, regrtest writes the backtrace to sys.stdout. If the backtrace contains a non-ASCII characters, it's encoded using sys.stdout encoding. In some conditions, sys.stdout is unable to encode some or all non-ASCII characters. Eg. if there is no locale set (empty environment or at least empty LANG variable value), sys.stdout.encoding=ascii. If regrtest fails to display a test output (error backtrace), regrtest exits directly (don't execute next tests). I propose to use backslashreplace error handler in sys.stdout, as done for sys.stderr to avoid this annoying issue. Attached patch (for py3k) replace sys.stdout by a new file using backslashreplace, just before executing the tests. I don't know if the issue concerns also Python2. -- files: regrtest_stdout_backslashreplace.patch keywords: patch messages: 104212 nosy: haypo severity: normal status: open title: regrtest: use backslashreplace error handler for stdout versions: Python 3.1, Python 3.2 Added file: http://bugs.python.org/file17090/regrtest_stdout_backslashreplace.patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue8533 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Either removing the fqdn call or just caching per connection it as the patch does is both fine. I doubt if someone is relying this logging anywhere in the code. This is useful only when BaseHTTPServer is started in the command like as a standalone HTTP server. I think we should totally remove the call to fqdn. The common practice with HTTP servers is to log numeric IPs and, if desired, let a batch log analysis process (such as awstats) deal with DNS resolution and caching.
