My custom scripts for starting/stopping multiple Zope instances
by Jim Cain 01 Feb '00

01 Feb '00

All, There have been some questions on here recently on how to start and stop Zope. The system I've created may not be the fanciest, but it works for me. It all begins with the standard SysV script in /etc/rc.d/init.d, which calls zstart and zstop as appropriate. This is fairly standard, and I won't bore you with the contents of my script here. zstart and zstop both read configuration files in /etc/zope.d/*, which currently contains two files: env and instances. The env file is sourced to redefine defaults that are set in zstart and zstop. The instances file describes how to start z2.py. I run ZServer on Red Hat 6.0 from behind Apache. Here is env: ---begin--- # /etc/zope.d/env # # Set environment variables that differ from default ZOPE_USER=www ZOPE_BASE=/usr/local/Zope ---end--- Here is instances: ---begin--- # /etc/zope.d/instances # # instance_name ftp_port n_threads use_manager # polonius 8022 2 0 gertrude 8023 2 1 ---end--- Here is zstart: ---start--- #!/bin/bash # # Set default environment # ENV_FILE=/etc/zope.d/env INSTANCES_FILE=/etc/zope.d/instances ZOPE_USER=nobody ZOPE_BASE=/opt/Zope CGIBIN_BASE=/home/httpd/cgi-bin INSTANCE_BASE=/home/httpd/zope PS="ps wax" PYTHON=/usr/local/bin/python # # process command line options # while getopts "c:" opt do case "$opt" in i) if [ -r "$OPTARG" ] then INSTANCES_FILE=$OPTARG else echo "$0: cannot read $OPTARG" exit 1 fi ;; e) if [ -r "$OPTARG" ] then ENV_FILE=$OPTARG else echo "$0: cannot read $OPTARG" exit 1 fi ;; ?) echo "Usage: $0 [-i instances-file] [-e environment-file]" exit 3 ;; esac done # # Read environment file # .

Annyeong haseyo. Arrghh... this is a can of worms. :) There are just way too many formats. For Chinese characters embedded in English, people use UTF8 (Unicode Transform Format?). Nice people use Unicode, but there are very few of them out there. :) Most people use BIG5 for the traditional characters, and GB (Guo Biao) for simplified characters. GB and BIG5 are two-byte encoded. You can tell from the first byte whether it's 7-bit ASCII character or a Chinese character. So, you can mix 7-bit ASCII characters and Chinese characters together without problem. There used to be a good website at www.ifcss.org, but always as things with the Chinese, people get political and fight between themselves, and sue each other in American courts. :) And voila, the website is gone. :) And now I am left in a limbo. You can probably find information just as fast as I do. Koreans are a lot luckier, as long as you don't use Hanja. :) Fact is, Korean is actually an alphabetized language. Typing Korean on computers is actually faster than typing Vietnamese. And Americans are eating up the rest of the world alive. Even the French are scratching their heads on what to do with http addresses... no one dares to use accented characters for their URL. Voila, so much for the defense of the French languages. It took internet to knock down the pride of the French. :) --------------------------- In short, I don't have a clue. :) Even after trying for a while on the web. I did do some work a while back with BIG5 and UTF8. But now I don't even know where to find info. regards!

PIL
by Daniel G. Rusch 01 Feb '00

01 Feb '00

I know that this isn't exactly a Zope question, but it is pyhton and I am using it in Zope :) I downloaded and installed the Python Image Library (PIL). How can I get the Python interpreter to find the PIL modules. In pyhton if I enter: >> import Image I get ImportError: No module named Image If I put Image.py into a directory that python currently knows about it finds it. The question then is how do I get the interpreter to know about the new PIL directory, I don't want to move all the files to an existing directory??? Thanks, DR

Zope/SuSE 6.x How-To v0.1 ready for review
by Jules 01 Feb '00

01 Feb '00

|At the end of boot.local, I put these lines... | |cd /zopedir ## Had to cd, or start would not run correctly |. /start & ## Running as a background process stopped it from | ## halting the rc boot process. | |It is crude, but it works. I don't know what, if anything, is the |downside of this approach, but I would certainly like to know if |there is one. The only problem I can see is that you're not calling PATH_TO_ZOPE/stop . Maybe one of the Zope Gods can point out if this is a Bad Thing. At 8IPC, the Digital Creations folks said that ZODB is pretty much bullet proof so it might not be a problem. If that was truly the case, why the stop script anyway? ;-) |Again, thanks, and perhaps this SHOULD be your first(?) HOW-TO on |your Zope member site!! Nice job. You're very kind. Thank you. Please have a look at http://www.zope.org/Members/jules/SuSE-6.3_html and let me know if anything is screwy with it. I've included my zope start script as a link in that page. The only problem I can see with the way I call start is that if it fails, I don't know about it at boot. My script simply forks the zope start script and that will always return success. Chris McD just warned about piping in this thread so ideas and tweeks gleefully accepted! Cheers, Jules PS Maybe if enough SuSE users drop SuSE a line, they'll include an RPM in the next version.

Newbie: Can Zope do this?
by Jacob Gorm Hansen 01 Feb '00

01 Feb '00

Hi, I need to develop a resource-localization system for an inhouse project. I want to be able to maintain a reference object hierachy of English texts, and a number of "mirror-hierachies", one for each locale, where translations can be entered. Something like: +English Hello world How are you? +German Hello world: Hallo Welt How are you: Wie gehts? +French... +Japanese.... >From what I've read so far, it seems I need to develop one or more Products (one for the English reference-texts, and one for the mirroring?), but I am unsure as to the possibilites of having objects mirror one another automatically. I guess I'll also have to use unicode or something, in order to support Japanese etc. Does Zope support that? Is this possible? How would this best be achieved? Thank you, Jacob

Zope & search engine indexing...
by addyd＠unk.edu 01 Feb '00

01 Feb '00

Is there any problem with Zope generated pages being indexed by search engines? I'm assuming that since a bot simply requests an URL (and "normal" URLs are one of Zope's strengths) that the bot will index the full page source assembled from the Zope object pieces by the server (the same source that would normally be rendered by the browser). Is this correct, or am I missing something? Darren Addy University of Nebraska at Kearney

I was using base64's encoding, but then I was still running into problems. I don't remember the exact situation, but base64 was not good enough. At the end, I had to switch to urllib, by using urllib.quote_plus() and urllib.unquote_plus(). The resulting string was bulkier, I didn't like it too much... but at least it did not fail like base64.

Dynamic sorting with dtml-in
by Ingo Assenmacher 01 Feb '00

01 Feb '00

Hi Zope-Folks! There is the question: I am displaying dynamic contents of a folder f using: <dtml-in "objectValues('type')"> [render stuff in a table] </dtml-in> So far, so good. I thought it would be nice, that when the user hits the table header of one coloumn of the table, the table gets reordered using <dtml-in "objectValues('type') sort=[new criteria]> So i factored the display method into a dtml-method called "show_table". But I simply can not figure out how to assign the sort attrib to the chosen value... I tried: <a href="show_table?sort=title">Title</a> but that did not work (as I thought) Any Ideas? Or do I have to rewrite the complete show_table to "show_table_sort_title"-stuff and call each seperately? There nust be a more Zopish thing to get that working. Regards, Ingo ------------------------------------------
