Writing to browser from an external script?
by Ken Whitesell 03 Oct '03

03 Oct '03

Here's the situation - I have a database that needs to be monitored. By that I mean that I want to "watch" a certain table from a PC, with live updates made when the contents in the database changes. The problem is that the HTML table being created is rather large, so I don't want to retransmit that every time. I want to leave the connection open, and just send a short javascript routine as needed to update the specific cell that has changed. (I've already gotten a trivial prototype of this concept working.) The way I was thinking about doing it is to spawn an external Python script as a separate thread. So, first I send the page with the contents at that moment. Without closing the connection, I issue a blocking read on a pipe. When the process that updates the database completes the transactions, it writes a message to the pipes of all waiting scripts (there could be a dozen or so machines watching this.) Each script then queries the tables for what has changed, builds the JavaScript code and writes that to the browser. (Again, trivial prototype of this concept is working.) Now, this was done from straight Python, using the CGIHTTPServer module as a base. What I'd really like to do is integrate this with Zope. In other words, I want the 'home' page to be a Zope object (DTML template?) that can initiate this external thread. (I'm assuming that it would have to be an external thread because of the need to block on the pipe.) First - the sanity check. Have I lost my mind wanting to do it this way? The common alternative that I usually read about involves sending the command to the browser to auto-refresh periodically. Unfortunately, that means that the entire page would have to be retransmitted every time - and I really don't want to have to do that. It just seems very wasteful to me to have to transmit 1000 times the amount of data necessary to just update (typically) 15-20 bytes. So I guess my biggest question is - how can I send data directly to the browser from an external script? (Can I pass the connection object to that script?) Failing that, is there a way that I can create a DTML template to iteratively call an external script, until the script returns some magic value? As you can see, I'm no expert at Zope, but I'm not one to shy away from doing my own research, either. I'm not asking anyone to do this for me, but a quick pointer as to what I should be reading about would be most appreciated. Oh, and once this is done, would anyone else be interested in seeing this? I don't mind sharing at all. (Just don't laugh...) Thanks in advance, Ken

retrieving a blob stored file from mysql
by Aaron Kunkle 03 Oct '03

03 Oct '03

I am trying to implement a feature on my site where users can upload a file (typically a tif file) for other users to download. I have the upload working fine and the download side works with Linux with Mozilla (my development system) but IE6 won't open the file as if it were a regular link. When you choose "save as" it works but if you choose "open with" to open the file with some kind of image viewer Windows complains that the temporary file does not exist. This is what I'm doing: 1. I link to my python script from my dtml document <a href="get_attachment?attachment_id=&dtml-attachment_id;">&dtml-doc_name;</a> 2. get_attachment result = context.sqlSelAttachmentByID(attachment_id = attachment_id) container.REQUEST.RESPONSE.setHeader('content-type', result[0].type) container.REQUEST.RESPONSE.setHeader('content-disposition', 'attachment;filename=' + result[0].doc_name) #content-disposition can use either: application, inline, or attachment return result[0].attachment I've tried using all 3 of those content-disposition settings with the same results. Does anyone know what I'm doing wrong? Thanks, Aaron Kunkle

Persistant Zombies and a sanity check
by Dennis Allison 02 Oct '03

02 Oct '03

I use htmldoc to generate pdf documents connecting to Zope via a simple popen2() call in an external procedure which pipes input to htmldoc and grabs output from htmldoc. The htmldoc process remains in the process table as a zombie and remains there until Zope is restarted. To avoid persistant zombies, I'll need to not use the factory function, popen2, and do a bit closer management of the process--that is, the parent will need to iexecute a wait on the child (htmldoc) so that when it completes the child process can die. Am I missing something? -dra

by Michael Bleijerveld 02 Oct '03

02 Oct '03

Hi, In the following DTML document I am trying to give the parameter 'dtml-sequence-item''to the setDirectory python script. This parameter doesn't return the right value. Instead it returns '<&dtml-sequence-item>'. What have I done wrong ? <dtml-in "admin.objectIds('Local Directory')"> <img src="/misc_/OFSP/Folder_icon.gif"> <a href=<dtml-var expr="setDirectory('<&dtml-sequence-item>')">> <dtml-var sequence-item></a> </dtml-in> Regards.

Problems with Formulator
by Eric Merritt 02 Oct '03

02 Oct '03

I am a relative zope newbie, and I am tring to use Formulator to render and validate a input form. For the most part everything works well, I do however have two problems. The first problem is that the form.header() and form.footer() pieces that are shown in most documentation cause and attribute error. There is an easy work around, you just put the <form> tags in yourself. It does, however, lead me to think that I am missing something somewhere becuase all the docs use this notation. The second piece is a bit more problematic. Following a bit of instruction by the zope labs folks I created the below script(python). When I try to call it in the application I get an authorization error. This generally makes sense considering the constraints zope puts on scripts, but it does make using a generic validator a bit more difficult. Does have any suggestions for a workaround? Thanks for the input, Eric from Products.Formulator.Form import FormValidationError req = context.REQUEST error = '' try: container.signup_form.validate_all_to_request(req) except FormValidationError, e: for i in e.errors: title = i.field.get_value('title') text = i.error_text error = error + '' + title + '' + text + '' error_html = "The following errors were found in the form:\ \ <blockquote style=\"color: red; font-size: 13px\">" + error + "</blockquote>" return error_html else: return container.yourScriptOrMethod() __________________________________ Do you Yahoo!?

IPTables and Zope
by Kevin Carlson 02 Oct '03

02 Oct '03

I recently setup some IPTables rules on Zope and for some reason I am being denied access to Zope. I am running zope behind Apache and using VirtualHostMonster together with Apache rewrite rules to make things work. The iptables rules I set up are as follows: iptables -P INPUT DROP iptables -A INPUT -p tcp --dport 80 -j ACCEPT iptables -A INPUT -p tcp --dport 8080 -j ACCEPT Both the output and forward queues are set to accept all. I can get to the ZMI (port 8080) with no problem, but I cannot get to the zope site through Apache (on port 80). Has anyone worked this out before? I have searched the archives and can't find anything on iptables outside of ftp setup... Thanks, Kevin
