Zope Code Exchange
by Jordan B. Baker 27 Apr '99

27 Apr '99

I have been working on a site that will allow people to contribute files into various categories. I was wondering if there would be any interest in a site for DTML and external methods to be categorized, searched and downloaded? Something along the lines of the PHP code exchange (http://px.sklar.com) Anyways, a couple questions: 1) Does anyone else think this is a good idea? 2) Does anyone know of other examples of this kind of site that we can draw on for inspiration? I think a Zope Code exchange would be a great place for new users to find common solutions to problems, also for seasoned users to find well-written methods so they don't have to re-invent the wheel. ------- Jordan B.

Database hosed!?
by Bill Anderson 27 Apr '99

27 Apr '99

Hello, after restarting one of my Zope servers, it fails and I get the following: ... raise DatabaseError, ( DatabaseError: The database contains records, starting at position 112192, that have time stamps 629676609.614 seconds in the future. This could lead to database corruption. Please double check your system clock! Now just how hte heck do I fix this one? (outside of modifying the code to ignore the date and hope I can fix it once it is up and running?)

New versions of a product
by Robert Leftwich 27 Apr '99

27 Apr '99

What is the best strategy to use when upgrading to a new version of a Zope Product that is already in production and has significant amounts of data in it? The issues are : 1. Modified hierarchy of objects 2. New classes/objects - not a problem as they don't exist in the earlier version. 3. Deleted classes/objects (i.e. no longer required) 4. Renamed classes/objects 5. New methods/attributes - not a problem as they don't exist in the earlier version. 6. Deleted methods/attributes (i.e. no longer required) 7. Renamed methods/attributes Robert Leftwich

I want to stream data through an external method.
by Jay, Dylan 27 Apr '99

27 Apr '99

What I have is several large files for downloading that I don't want to put inside BoboPOS as importing them seems to take forever. It is also more convienient if they exist outside the OODB. So what I want to do is for the user to dl the file through Zope. I have the following external method that works def serveFile(self, file, RESPONSE): RESPONSE.setHeader('Content-type', 'application/x-msdownload') dl_name = "C:/Provision/downloads/"+file dl_file = open(dl_name,'rb') retval = dl_file.read() dl_file.close() return retval However I think this is quite inefficient and will probably not work when large number of users attempt to download the same file at the same time. Anyone have a better solution?

Authentication with ie5 and zope.
by Jay, Dylan 27 Apr '99

27 Apr '99

Has anyone found a solution to basic authentication with ie5 and iis4.0. This is HUGE problem for me as my site has to go live in less than a week and it relies on have users authenticate themselves through the UserDB package. If they can't use ie5.0 to do this, then I have a big problem.

RE: [Zope] Has anyone tried to make Zope invisible using IIS
by Jay, Dylan 27 Apr '99

27 Apr '99

I tried using the isapi filter and it only sort of works. Any links of the first page use the original address not the one that was filtered. What I would like is for it to be completely transparent ie all links point to the virtual directory not the exe file. I assume this doesn't work because of the BASE tag that zope puts in the header. It also won't work because of my use of BASE0..n tags etc. How can these problems be overcome? > -----Original Message----- > From: Brian Lloyd [mailto:Brian@digicool.com] > Sent: Thursday, 15 April 1999 23:58 > To: 'Jay, Dylan'; 'zope(a)zope.org' > Subject: RE: [Zope] Has anyone tried to make Zope invisible using IIS > > > > I basically want to make a virtual directory that points to > > everything on > > the other side of the PCGI exe file however stupid IIS seems > > to be only able > > to make a real directory a virtual directory.

Re: [Zope] [off topic] question?

Well, there are a dozen of fine languages older than Java. What happened is that Java caught the attention of the big media because of the responsivity of web applets in HotJava, the first java-enabled web browser. Java was the first language to be "known" by Wall Street before it was known to programmers. The name of the language, "java", was aptly chosen, too. BB
