Re: [Zope-dev] Using Java-Script with DTML
If you don't mind the complication, you can use the xml-rpc Java Applet (I can't remember where it comes from) and the Javascript hooks that it provides to make xml-rpc calls from javscript to Zope. >> Original Message << On 6/29/00, 10:14:06 AM, Hung Jung Lu <[EMAIL PROTECTED]> wrote regarding Re: [Zope-dev] Using Java-Script with DTML: > --- In [EMAIL PROTECTED], Thomas Weholt <[EMAIL PROTECTED]> wrote: > > >not work, of course.

Re: [Zope-dev] Product Data Storage
Just my $0.02 worth... If you can at all avoid it, I think you should find a way to store it in the ZODB. Maybe a Configuration product that would allow you to create arbitrary configuration information and still be able to access it without making filesystem calls. Think about DC's Zope on a CD demo. Not that you really need to do that sort of thing, but it's really not going to work if you have to write stuff to the filesystem. Actually, an XML Docment somewhere at root level should give you the kind of flexibility you're looking for. Lot's of people are using XML files for conf these days (they're all jumping... don't you want to...) That being said, I totally agree that if you need to store something in a file, put it in Zope/var. I, for one, have my Zope application code on partition along with other apps, and the data, like Data.fs on another. I typically don't expect the apps partition to grow very much, or very often, In fact, only when I install something. So it would be quite shocking to have that space filling unexpectedly. But, as always, the choice is completely up to you. Monty >> Original Message << On 6/30/00, 3:27:42 PM, Dan "L."

[Zope-dev] ZEO Replication/Cache
I just installed an instance of ZEO Storage Server with a client on the same machine and a client on a different machine. So far, it seems to work reasonably well, with one exception. None of the changes I've made on one client seem to propagate to the other client unless I restart the other client. This can't be the intended modus operendi.

Re: [Zope-dev] Overriding a method in an instance.
It seems to me that the problem here is in appearance. Although it seems that you're aquiring an index_html or searchResults in those cases, they are actually instantiated in scope just like anything else you'd add inside that particular object, you just can't see them. So you have two choices. Sub-class Tracker or Squishdot and override that way. OR Make a folder that contains the overridden methods and call things through the context of that folder. In the case of what it seems you want to do I'd say sub-classing is going to be your real answer. Hope that helps...

[Zope-dev] MySQL Transaction Support
We were talking about this a while back and I believe came to a consensus about having two different ZMySQL adapters, one for transactions, one for not. However, since each table can have a different type, this might not bode too well for someone that needs a connection to draw from one table with BDB and one without. If you look at the output of the mysqldump utility, using --opt, it shows both server version and table type. I think we should be able to add a function to _mysql.c that would expose that information on a per-table basis. We could then make the call as to whether the sever supports transactions or not. A question would be, what should the commit/rollback mechanism decide to do when the transaction deals with tables of both types. I would suggest a default behavior of not allowing transactions in a mixed type situation, with a way to set an overriding option to allow the rollbackable table to be rolled back and leave the other as is. Hopefully the application designed wouldn't cause that kind of insanity, but hey, if they want to, they'll find a way. Does anyone have any thoughts on this approach? Baring any blaring negative comments, I'll start working on knocking up something like this.

Good point. It still irks me to have two DA's though. It gets confusing enough with the three different DA's running around now, much less if one of them actually had two valid versions. What if we had two classes like you said, but then in the manage_addForm had a checkbox for Transactions enabled, which would determine which Class got instantiated?

Re: [Zope-dev] [Zope] App isolation
I'm fairly sure there's already a Zope COM interface, and I know Zope can do xml-rpc. And SOAP support is coming.

[Zope-dev] Shared Libraries and Persistent Objects
Hey guys, I've got a question about how Zope deals with shared libraries. Say I have a 2Meg shared library that I've generated with SWIG. (I know it's big, but for sake of argument) Say then that I create a Python Class that imports this library and provides a front-end for each of its exported methods. Then, I instantiate this class 2000 times within a Zope instance. My question is, the library code is loaded into memory once, right? That seems to be what should happen, but I want to make sure before I start selling people here on SWIGing a few utilities and bundling them into one of our Zope objects instead of doing fork/execs to call an executable. I'm not shifting the burden from loading time to storage size, am I?

I think I'd like to talk to you about this. We're about to work on
transitioning a web-based product to Zope, and we use Store Procedures
exclusively. I'd love to have the extra ZSQL goo instead of having to wrap
the code at such an individual level. Maybe we can stick someone on the task.
But I'm sure we'll need a guiding hand or two. All of this assumes I can get
past the basic problem that follows...

I've been looking through that code (we've started using DCOracleStorage on
the backend.) For some reason, though, I can't get the stored procedure stuff
to work like you do. Check out the following:

[Zope-dev] ZMySQLDA transaction issues.
We were chatting a while back about how to handle the MySQL issue of support/non-support for transactions, with the dominant suggestion at the time being two DAs. I just got done talking with Michael Widenius (Monty of MySQL fame) and he offered to add a warning on rollback if the table doesn't support transactions. So what I'm going to do is this, unless anyone can raise a beefy suggestion. 1) Actually get off my ass and incorporate all of adustman's MySQLdb changes into my ZMySQLDA. :) 2) Make transactions un-supported until the release of MySQL that contains the warning. Since the 3.23 line is pre-release, there shouldn't be any issues with people using a version of MySQL that supports transactions but not being able to upgrade to one that ZMySQLDA supports (you should never be that tied to a pre-release version of anything.) 3) For all MySQL versions that we don't 'officially' support as having transactions, throw an exception if a rollback is attempted. 4) Include a config option to turn off the exceptions. I believe we should be able to keep a simple, and single, ZMySQLDA this way. But please, shoot holes in the plan for me.
