Q: JPython: AttributeError: java package 'org.python.modules' has no attribute __path__
by markwatson1＠my-deja.com Jan. 30, 2000

Jan. 30, 2000

Sorry in advance if this is a FAQ (I looked, but could not find anything on the JPython bug list). I am trying to use the jpythonc compiler with the -c or -a options and I always get this error: AttributeError: java package 'org.python.modules' has no attribute "__path__" I get this same error under Linux and under NT. Any ideas? Thanks!, Mark Watson www.markwatson.com Sent via Deja.com http://www.deja.com/ Before you buy.

Embedding -- getting error/traceback information not to stderr?
by erw＠dde.dk Jan. 30, 2000

Jan. 30, 2000

In my application using embedded Python, I'd like to print out the error information as it occurrs (traceback, etc.). This is what PyErr_PrintEx() (called from PyErr_Print()) does -- unfortunately, it does it to sys.stderr. Did I miss some other similar function that will return the nicely formatted exception information in a variable? Otherwise it looks like my options are: 1) copy PyErr_Print(), modify it to append to a file (yuck!) 2) Modify sys.stderr to append to an internal buffer instead of a file 2) seems to be a better option (I'm not certain it's possible). PS: Where does the filename in the stack trace messages come from? I can't quite find it in the code: I create my modules with PyImport_AddModule and setup a restricted environment then parse the code from a file. I've __file__, but maybe I do it too late. -- ============================================================================== Erwin Andreasen Herlev, Denmark <erw(a)dde.dk> UNIX System Programmer <URL:http://www.andreasen.org> <*> Goodbye, Richard! ==============================================================================

mimecntl 1.4
by Michael P. Reilly Jan. 30, 2000

Jan. 30, 2000

I have created a new version of my mimecntl module based on patches from users. The new version is 1.4. Mimecntl is a module which encapsulates MIME documents as mutable objects and subobjects. Multipart content-type behaves like UserList, most other times act like files. The original purpose of this module was to create a single mechanism for reading and written MIME files (I found it hard to integrate mimetools and MimeWriter). The module can be downloaded from <URL: http://starship.python.net/~arcege/modules/mimecntl.py> What has been fixed since the last announced release: * a new method of MIME_document has been added to check file objects; this was made as a method to be overridden by subclasses if necessary; such objects require a 'seek' method; * MIME field content now handle case-insensitive; * a bug copying a Field instance; * added an old fix that I mistakenly never included to truncate then decoding/encoding. Thanks to Josef Sachs, Bill Bumgarder and Riccardo Murri for their aid. -Arcege

Python Ring Info

Python ring Info ------------------------- This is a piece of information about the existing python ring in: http://www.ctv.es/USERS/irmina/pythonring.html (now with Statistics) What is it? >From a functional point of view, it's a list of linked web sites that share a common interest or information, in this case python related stuff. How does it work? The HTML code included in each node of the ring calls a CGI that performs the movement thru the ring. How can I join? In the above web site , fill in your data and that's all. Why I should ? If you've done a web site, I think it's worth you spend 15 minutes promoting it, after your web site has been included in it you'll get more hits than ever. Moreover, your information may be interesting for other people, or you can be interested in other people's work, a big Webring provides the community a lot of unusual but somehow interesting data. How can I get more hits? Because the Webring is a democratic way of organization, that is, all its members tend to receive the same ammount of visits, the big ones as much as the small ones. Well, I don't have a Web page.., so? So you must ( :) ) start doing one right now. Seriously, we ( at least me,MGA) are interested in people's work, perhaps you've been collecting data or even your libraries or methods of work are clearly defined, the ammount of time required for a fast compilation of that info is not too much. And I remark that you can learn only if all ( or many) want to show or teach what they know. Of course we admit commercial Web sites also, *any* Web site about python. Thanks for your time and patience reading this. MGA

Creating a local variable with a parameterized name
by Michael Ross Jan. 30, 2000

Jan. 30, 2000

I'm new to this, so I hope I'm not missing something obvious... I want to create a local variable with a passed in name. I realize I can do the following: >>> def f(varname): cmd = '%s = 123' % varname exec(cmd) cmd = 'print %s' % varname exec(cmd) >>> f('mike') 123 >>> But exec needs to invoke the parser, which seems to be an extremely costly thing to do. It seems local variables are stored in a special, inaccesible (from python) place in the frame object (I've been looking at PyFrame_FastToLocals and PyFrame_LocalsToFast). Do I need to write C code to do this? A builtin to do this would be nice... Thanks in advance! Mike Ross

As you have discovered, there are ways to do that, but none of them are pretty. Are you sure that you really need the name to be a variable on its own, and that a dictionary wouldn't do? That is, instead of things like: cmd = '%s = 123' % varname exec(cmd) cmd = 'print %s' % varname exec(cmd) You could probably do things like this: my_directory = {} my_directory[varname] = 123 print my_directory[varname] Instead of creating a variable whose name is the value of 'varname', it makes a directory with a key equal to the value of 'varname'. There are very few situations of this type that I can think of where this would not be sufficient. Directories are handy, and particularly well suited to this sort of thing. Why be any messier than you need to be? -Justin

Announcing Gadfly COM Object
by marc_risney＠my-deja.com Jan. 30, 2000

Jan. 30, 2000

Ok, I just put up 0.51 beta, a little closer, a little smoother, but still needs some work I need to do a better job with recordset.EOF and .BOF as far as Looping goes, mebee someone can jump in and help out here. I need to clean up a bit and would like to add some sort of DB.help Aaron has a whole slew of goodies when you go into Client/Server mode via gfclient, and it sounds like he is going to add more with Gadfly 2.0, SHUTDOWN, RESTART, CHECKPOINT, EXCUTED_PREARED, etc... I need to add the server commands and I will probably chuck some VB and Delphi Clients together, and some MS Excel and Access demos using the object. For now I have a lowly VBScript demo...oh well you get the point I was inspired by ADO which is incredibly easy to use when scripting with ASP and VBScript. but I luv the idea of serving my Gadfly data from a Linux box and connecting to it via a port with a pretty VB Form on my NT Box. Again the idea is to give it similar functionality to ADO, but after the basics are covered, add the good stuff. One other thing; a bit on a tangent really, if anyone tells you that Oracle Lite is reaally easy, non complicated and small to install is a Liar, and obviously has never w orked with Gadfly before, a true multi-platform small footprint RDBMS soory Larry..yer' product is sucks at any rate the 0.51 beta for the Gadfly COM server can be found at the following: http://www.blazesoft.com/~mrisney/comgadfly.py and a sample VBScript at http://www.blazesoft.com/~mrisney/conn_gadfly.vbs Sent via Deja.com http://www.deja.com/ Before you buy.

Subclassing ExtensionClasses in C?
by James Henstridge Jan. 30, 2000

Jan. 30, 2000

Hello, I have a small question about using ExtensionClass with my python module. It was suggested to me recently that I may want to look at rewriting my python extension pygtk to use ExtensionClasses (to increase speed, decrease mem usage, and a few other benefits). For those who have not used pygtk, it is a wrapper for the GTK GUI widget set (see www.gtk.org). If I switched over to using ExtensionClass, I would want to create a heirachy of ExtensionClasses implemented in C as wrappers for the various widgets. Looking through the documentation for ExtensionClass, it has examples of how to create classes in C that can be subclassed in python, but it does not seem to have any examples of how to write one extension class that subclasses another extension class. I assume that this is possible, but I haven't seen any examples. Is it possible to do with the public ExtensionClass API, or is it a little more difficult. If anyone can help with this, I would appreciate it. Thanks in advance, James Henstridge.
