[Zope3-Users] Various zope3 packages release
Hi I've created some generic packages while working on an application and put them on http://www.jellofishi.com/zope. The code was last touched about half a year ago, and was last tested against 3.3.1. Please excuse any stupidities or anything that is no longer relevant, and enjoy :) I don't read the list too often, so any feedback or questions should be sent directly to me. ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users

[Zope3-Users] z.a.component.vocabulary.UtilityNameTerm bad implementation ?
hi using zope3.3.0 on gentoo zope.app.component.vocabulary.UtilityNameTerm is marked as implementing ITokenizedTerm, but in fact tries to implement ITitledTokenizedTerm, and fails at that, because token and title are implemented as methods not properties. bug ? ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users

[Zope3-Users] problem trying to use layers in a custom skin
hi. (using zope 3.3.0) i'm trying to make my own skin, using rotterdam as a basic layer, and adding my own layer. this is what i have so far : the classes : class jzclean(IBrowserRequest): """Layer for registering jzclean-specific resources.""" class JZClean(jzclean, rotterdam, IDefaultBrowserLayer): """The ``JZClean`` skin. It is available via ``++skin++JZClean``. """ configure.zcml : and then i set the default skin to JZClean : when i go to http://localhost:8080/@@/zope3_tablelayout.css i get the rotterdam version. when i remove rotterdam from the layers, i get my version. tried moving rotterdam and jzclean around in the inheritance list, but that didn't help. could somebody give me a clue ? ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users
[Zope3-Users] problems using os.popen2 in a heavily used utility
Hi.
i have a utility that generates thumbnails for objects that can be displayed
as an image (faxes).
the part that generates the thumbnail :
def generate_thumbnail(self, data):
"""Return a smaller view of the data stream"""
# if data stream is a djvu file, convert it to ps before
thumbnailing.
magic = getUtility(IFileMagic)
mimetype = magic.getMimeType(data)
if mimetype == "image/x.djvu":
(stdin, stdout) = os.popen2("djvups - -")
stdin.write(data)
stdin.close()
data = stdout.read()
stdout.close()
# Explenation of convert command line attributes :
# -resize 150 : resize, while keeping aspect ratio, to a width
of 150 pixels
# -[1] : input file in stdin (-) to extract only frame 1:
-[1]).
#format detected automatically from data stream
# png:- : output file on stdout (-) in png (png:) format
(stdin, stdout) = os.popen2("convert -quiet -resize 150 -
png:-")
stdin.write(data)
stdin.close()
thumbnail = stdout.read()
stdout.close()
return thumbnail
this utility is used by a view that displays a grid of a few thumbnails.
when the view is loaded, several thumbnails are generated at once. (calls from
the tags to an /@@thumbnail view on the obect)
some thumbnail make it through (very few), the rest fail with :

thumbnail = stdout.read()
IOError: [Errno 4] Interrupted system call
i read somewhere that os.popen2 is not friendly towards twisted framework, and
that twisted.internet.reactor.spawnProcess or
twisted.internet.process.Process should be used.
i can't undersnad what format the parameter childfds should look like when
calling those. could somebody show me the equivalent of (stdin, stdout) =
os.popen2() ?
