danger: FCGIServer.py rev 1.5 breaks fastcgi for me.
by Anthony Baxter 29 Nov '99

29 Nov '99

I'm running Zope on a Linux box (redhat 5.2) and have mod_fastcgi_SNAP_Oct06 compiled into Apache 1.3.9 on a Solaris x86 box. This patch, from FCGIServer.py r1.4 to r1.5 utterly breaks FCGI support. Any attempt to connect via FCGI makes zope go into an infinite loop, gobbling up memory. Yes, this is in the collector now, but it's worth mentioning it to zope-dev so anyone else who is trying to make this work doesn't end up screaming and ranting... (As an aside - how do I get CVS to checkout a particular revision of a particular file? Can I do this?)

Sybase DA import error

I seem to be getting in import error when testing the SyBase adapter. import error follows: >>> import ctsybase Traceback (innermost last): File "<stdin>", line 1, in ? ImportError: /opt/sybase-11.9.2/lib/libct.so: undefined symbol: scl_sess_alloc Any ideas? I have reinstalled the rpm to no avail (as expected).

Best way to email a newsletter to thousands of recipients from a Zope site Zope site
by Itai Tavor 29 Nov '99

29 Nov '99

Hi, I need to add a newsletter feature to a Zope site. Interested people will be able to register their email addresses, and the newsletter will be mailed to all addresses every 1-2 weeks. The number of recipients could potentially have 4 zeroes in it (and no, it won't be 0000). What would be the best way to do the mailing? Use mailhost with a very long recipient list? Call mailhost once for every recipient? Use some external tool to do the mailing?

MIMETag.py patch
by Ava 29 Nov '99

29 Nov '99

Hello, I found myself having a need to send mail with the ability to customize stuff like disposition, name, filename, encoding, etc. I modified the MIMETag to allow the use of type_expr, disposition_expr, encode_expr, name_expr, filename_expr, and skip_expr attributes in the mime and boundary tags. * type_expr, disposition_expr, encode_expr, and name_expr work like type, disposition, encode and name, except that they take expressions instead of names. * filename_expr allows to give the filename of the attachment. Note that the filename attribute is included only if the disposition attribute is set, and that in the header, the filename attribute is attached to the Content-Disposition: header, just like the name attribute is attached to the Content-Type: header. I don't know if it is ok, but it seems to be the way Netscape Messenger and Microsoft Outlook do it. * skip_expr allows to skip an attachment if the skip_expr evaluates to true. Here is an example. document is a FileUpload object. <dtml-sendmail mailhost=MailHost> to: you(a)anywhere.com from: me(a)nowhere.com subject: this is the subject <dtml-mime type=text/plain> Thanks for you input. <dtml-if "document.filename"> The file you attached is <dtml-var "document.filename"> <dtml-else> You did not attach any file </dtml-if> <dtml-boundary disposition=attachment filename_expr="document.filename" name_expr="document.filename" skip_expr="not document.filename" type_expr="document.headers['Content-Type']" encode=base64><dtml-var "document.read()"></dtml-mime> </dtml-sendmail> Please send me any comment on this work.

I'm trying to override manage_beforeDelete(self,item,container) in a python class that inherits CatalogAware.

Using asyncore in external methods
by Petru Paler 28 Nov '99

28 Nov '99

Hi, I have an external method which calls a function from a module. That module opens a couple of sockets and polls on them. The problem is that 'socket_map' from asyncore.py is global, so things conflict with ZServer's use of asyncore. Which is 'the right way' to use asyncore with Zope ? -Petru

Lobby: Renderable ZClasses
by Lalo Martins 27 Nov '99

27 Nov '99

Kevin Howe wrote a version of my ``Renderable base ZClass'' which plugs directly into the ZClass system. Background info: a Renderable ZClass is one with control of what happens when you <dtml-var some_object_of_this_class>. Kevin's version is really cool, but it patches stuff outside Products/Renderable, so I won't distribute it as the ``official'' Renderable Product. Still, I'd like to lobby for its inclusion in Zope itself. How it works: when you create your ZClass, you select ``Renderable'' as one of the base classes. Then (in Kevin's version) in the Basic tab you select some method to be executed when people <dtml-var some_object_of_this_class>. My BannerAd Product and Kevin's ActiveImage Product both use Renderable. AFAIK, both work with my version and Kevin's. []s, |alo +---- -- I am Lalo of deB-org. You will be freed.
