Hi, Anyone using Zope on (RedHat) Linux? I couldn't find a init script anywhere, but before I write it myself; did anyone write such a script already? Thnx Jonathan -- UR Communications - Solutions for a wired world Who, what & where @ http://www.ur.nl/

ADVICE needed: multi-site Zope installations, PCGI and ZServer
by Tony McDonald 15 Sep '99

15 Sep '99

Hi all, I'd like to gather the collective wisdom of the list on this situation I need to sort out; 1) We run Apache with lots of virtual servers. Within the virtual servers I have Rewrite rules that point to various subfolders of a Zope 1.10.3 installation, which uses PCGI. Each one of the subfolders corresponds to a site that shares a set of core DTML, ZSQL and External methods, along with their customizations specific to that subfolder (subsite). 2) This works, but the manage screens for the subsites are mangled, which can lead the admins of those sites getting very confused. I understand that this is something that can only be fixed in the innards of ZPublisher, ie beyond my ken. [DC guys - this is definitely a pain for those wanting to run several subsites from a single Zope installation, thus taking care of shared methods etc.] 3) I'm also running a Zope 2.0.0 system on a higher port number using ZServer (ie bypassing the Apache server entirely). I'm in the process of shifting parts of the 1.10.3 site to this 2.0.0 site. This site is quite fast and I'm pleased with it. The intention is to run the main site and the subsites from this installation. 4) What I *want* to do is save the effort of exporting (and keeping up to date!) to different installations of Zopethe various core methods I have in the 1.10.3 installation, whilst at the same time allowing the virtual hosts to point to subfolders in the main distribution. I also want maximum speed and to be able to keep all my Zope products *for all the subsites* in one place. (I want, I want....) 5) If I understand it correctly, if I use Apache to manage the virtual servers I *have* to use PCGI rather than ZServer. PCGI is approximately 4 times slower than ZServer (this from a Jason Thaxter email of 1/9/99) "While many benchmarking stats are meaningless, I can support Amos' basic contention that zerver is about 4x faster that apache/pcgi/zerver." My questions are: Can I *somehow* use Apache to manage the virtual hosts (passing on the authentication headers) to a ZServer based Zope instance. This way I get Apache logging and other benefits? Can I split this instance into subsites that get less confused management screens? As I'm using MySQL as my database adapter, which is currently not thread-safe, am I better off just creating these subsites separately and running three or four different Zope instances? Should I use the SOFTWARE_HOME and INSTANCE_HOME variables to run several Zope instances (each containing what would be a subsite), but only one software instance, thus keeping all my External methods and Products in one place? (and if so, any pointers on how to do this would be great) any thoughts on this would be appreciated.

REQUEST.traverse builds up a list of parents, so this could be used as a context for NotFound errors. It will also enable us to customize the error message. Can't we somehow pass the list build by REQUEST.traverse back to ZPublisher.Publish.publish, and then use this list for finding the standard_error_message? -- Martijn Pieters, Web Developer | Antraciet http://www.antraciet.nl | Tel: +31-35-7502100 Fax: +31-35-7502111 | mailto:mj@antraciet.nl http://www.antraciet.nl/~mj | PGP: http://wwwkeys.nl.pgp.net:11371/pks/lookup?op=get&search=0xA8A32149 ------------------------------------------

Strange 'with' behavior? (Q1959)
by picasso＠videotron.ca 15 Sep '99

15 Sep '99

Hi, I made another stupid test with strange results: in '/myCDs/' I wrote a DTML Method called 'test': <dtml-with 0001> </dtml-with> 0001 is a ZClass object in myCDs. When I click on the tab view, I was asked to download the file 'test'. I did it. The downloaded file is empty. Sure the test is not very useful, but I try to undestand better how Zope works. Does anyone, can explain the result of my 'test'. Thanks.

i am trying to get the bobobase_modification_time of a DTML-document(news) within a folder (content). Tried lots of variants looking like :      - but this always turns out the bobobase_modification_time for the folder(content) instead of the document (news).

Add new item menu...
by Francisco Sam Castillo 15 Sep '99

15 Sep '99

Hello, I been trying to limit the options that get display on define group of users, Is there a way to limit the options on the selection drop menu for a "Add a new item" for a specific previously define group? The case is that I jus want some of the currently install products to show up on some groups and other on another set of groups but not all, because even when I have deny permissions to create new objects they still appear and then the users can install what ever they want, and this is not good, hope some one cud give, hint or a clue as to how to acomplish this task. Thanks in advanced Sam

zGold
by Phil Harris 15 Sep '99

15 Sep '99

Hi all, Just a note about zGold. It seems to be creating a lot of interest (my surprise knows no bounds), but one thing I would like to say . This is a work in progress and is by no means a final production, that means that there are probably bugs and lots of them. I don't think it should be used out of the box for anything more than it's intended purpose, namely, look at the code and then fix it for your purposes. zGold was created as a learning aid, don't base your livelyhood on it. That said, I'm more than willing to help develop it in anyway. Thanks for listening. Phil phil(a)philh.org ~~~~~~~~~~
