why can zope not handle large files
by Christopher N. Deckard 21 May '01

21 May '01

For a project we are working on we have export of an MS Access database as csv (comma seperated) files. The csv file is about 37MB with rows of 18 numbers sepearted by commas. The file has been uploaded into Zope and then we are trying to insert each row into a PostgreSQL database using either the PoPy or PsycoPG database adapter. Basically Zope never comes back from trying to do this. We have also tested against Oracle with the same results. It's been run on an Athlon 600 and a Sun E450. Zope just starts to take up more and more memory eventually filling up swap and never completing the transaction. If we split the 37MB file up into small 3-4MB chunks, everything works fine. But it just can't handle the larger file. To me, 37MB doesn't seem like much. If it were .5GB, I could understand Zope having problems. How can I get this to work? I am not on the zope list (though I'll probably subscribe here in a moment) so please CC me on a reply. Thanks, -Chris

I would take the second tack. Please CC the zope-cmf list with any replies, as the community of folks who share your interests is more focused there.

simple workflow system
by Timothy Wilson 21 May '01

21 May '01

Hi everyone, I'm working on a project and I'd like to implement a simple workflow system. There would be "reviewers," "contributors," and anonymous visitors would be able to submit content too. Should I: 1. Have the item cataloged after it is reviewed and approved. (I believe this is how Zope.org functions.) 2. Catalog everything, but have a property called "published" that only the reviewers can set and use Zope's security mechanism to prevent viewing unpublished content for anonymous visitors. 3. Use the CMF. 4. Something else My concern about the CMF is that it seems to be an all-or-nothing package at this point. I really don't need the membership part of it because my site is 99.99% read-only. It's a small group of people creating the content. Any thoughts? -Tim -- Tim Wilson | Visit Sibley online: | Check out: Henry Sibley HS | http://www.isd197.org | http://www.zope.org W.

RE: [Zope] Q: Verifying the poll numbers
by Max Møller Rasmussen 21 May '01

21 May '01

> From: Paul Everitt [mailto:paul@digicool.com] > OK, on to the discussion. Are those numbers *really* > accurate? I gotta My biggest beef with the numbers is that the poll is missing the most obvious category. Pre-built Lego style interoperable modules that you can just install and then have them automagically work together on a site. If the module is there it shows up in the site structure, if it isn't, there is no trace of it. Oh yes ... and a smart way to syndicate stuff. As far as I can see soon we will all have our own personal portal for various reasons. (Big ego's being one). At the same time I see all the major portals crosslinking excessively to each other. All off them having their own articles and discussions around one "source" article. It ought to be easy to be a syndicator of both articles and comments, so that articles and comments from several sites will be synchronized automagically. And while we are at it we should make it easy for all Zope products to do this. Calendars would also be easily sync'able then. Well anyway ... I am currently planning/building both of the above, I'll get back when the code is sound. Regards Max M

thread safety
by Jerome Alet 21 May '01

21 May '01

Hi, In the ZShell external method I've written, I've got some code which does the shell globbing for wildcards using the glob.glob module after having redirected some methods from the os module to my own, e.g. : --- CUT --- oldlistdir = os.listdir os.listdir = mylistdir ... glob.glob(...) ... os.listdir = oldlistdir ... --- CUT --- So my question is: is this code thread safe, wrt to other Zope threads accessing the os module methods while they are redirected to mine ? I don't want other Zope threads to access my own methods, just the current one. If it is not thread safe, then how can I do it another way ? Thanks in advance. Jerome Alet - alet(a)unice.fr

At the web you can only make some guesses how long a user stays on a page. You never will get feedback if the user simply goes elsewhere or closes the browser. For pay per view (in your case for time) you may - use a specialized application to play the video (not user friendly :) - force the user to do something to keep the video stream alive (also not user friendly :) First do a decision about which way you ensure pay-per-time then think about the implementation. An option would be of course pay-per-view without time limitation. Regards, Frank
