[Zope-Checkins] SVN: Zope/trunk/lib/python/Products/PageTemplates/ - in-place migration to unicode
Log message for revision 71644:
- in-place migration to unicode
- the ZMI edit view now *always* uses 'utf-8' and no longer uses
self.output_encoding (which is only relevant for FTP/WebDAV)
- 'output_encoding' is now a property

It also makes it under appreciated. I made a start at fixing this yesterday: http://svn.zope.org/zdaemon/trunk/src/zdaemon/README.txt?view=auto It isn't very hard to use, so documenting it isn't really all that hard. ...which is almost True for a lot of parts of the Zope 2 core :-) I wonder if we should be using some other daemon manager. Arguably, there's no reason for the Zope project to maintain one if something is available that does what we need. I think (meanwhile) that this is not enough to justify the replacement of a component. Replacing a Zope 2 component always caused some pain. So as a rule for replacing something in the Zope 2 core we consider those rules: - the replacement solves existing functional problems - it adds major functional benefits - no issues with backward compatibility, well tested etc. For the Zope 2 core we must be very careful about changing stuff. Stability and backward compatibility are much, much more important for the end-user than satisfying our replace-all-with-something-better drive :-) Don't get me wrong but we've done some minor mistakes with replacing stuff in the past and because of that I became a bit conservative about changing things. Of course I am only speaking for the Zope 2 core. I feel the same need for conservatism. These are all good arguments. A strong counter force is that we seem to have more on our plate than we can handle. We either need to get more people helping, or we need to do less. Something to keep in mind is that many people who help now actually want and deserver to be able to do new things too. :) zdaemon is an interesting case because it is s non-zope and (mostly) non-python specific. I must say that it amazes me that there isn't an established alternative out there. One point in zdaemon's favor that I forgot about in my original analysis is that it has a (also undocumented) subclassing API that allows applications to add new commands. We certainly leverage this to provide the debug and run commands. supervisor2 looks very cool. But it is also ours in some sense. It also is much bigger than zdaemon. It looks like like something that people will often choose over zdaemon. zdaemon is still attractive to me over supervisor2 because it is smaller, less ambitious and I already understand it. :) And, of course, there are the good backward compatibility arguments that you make.

The underdocumented argument is unjustified in my view: * zdaemon comes with reasonable online documentation (the help command) * like for all zconfig based programs, essential documentation can be found in the schema file. As the configuration options have been carefully documented (also quite common for zconfig based programs), this is sufficient documentation for the configuration. * There are other forms of documentation than testable documentation (aka doctests). -- Dieter ___ Zope-Dev maillist - Zope-Dev@zope.org http://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope )

Hmm. I doubt that you have really seen this text. There should be something
in between the in and the ignored. It is *vital* that you
are as precise as possible in your problem reports...
Python emits messages of the kind above in some (rare) situations,
e.g. when exceptions occur in destructors.
The exception above seems to have been raised in such a situation.
The missing thing betwenn in and ignored should tell us which situation
this was.
It tells you that something tries to access the attribute thisown
on a ShapeFile instance but this does not have the attribute.

Another tip for the future. When you report problems, you need
to include full error information. Beside the Error Type and

You find all this information in the error_log object in

No idea what shapelib is doing but reading a file from the locale
filesystem as it seems to work from an external method is *different* from
a accessing
content that is stored within the ZODB. I really wonder why you think it
would work the same way? The hierarchical object storage of Zope looks
similar to a filesystem but it is not a filesystem and the Python APIs for
accessing filesystems don't apply. We have no idea what the ShapeFile
constructors expects as data. If it expects a filename of a file within the
filesystem then you must obtain the content of your data stored within the
ZODB, create a temporary file and call the constructor as you did within
your external method. Possibly the constructor accepts the data directly
as *string*..in this case this would make things a bit easier. But it is up
to *you* to check the Shapelib API and take appropriate action.
