Using Apache rewrite to server Zope/Plone - VirtualHostMonster and / or SiteAccess?
by Cormac McClean 18 Jun '04

18 Jun '04

Hi, I'm running Debian 3.0, Python 2.3.3, Zope 2.7 and Plone 2.0.3. I have Apache 1.3.27 running, and I am attempting to serve a Plone site via Apache's rewrite rules. Here's how things are set up: Apache DocumentRoot at /usr/local/apache/htdocs, contains a folder zope Within Zope, I have a folder, zope, which contains a Plone site (erebus_plone) and a Virtual host monster. Apache is running on the institute's internal network (only) at erebus.ait.ie (port 80), and Zope is on erebus.ait.ie:8080 I want the Plone site to appear in response to http://erebus.ait.ie (I need to retain Apache for cgi-bin and other legacy content). Here's what I have in httpd.conf: DocumentRoot /usr/local/apache/htdocs/zope RewriteEngine On RewriteLog "/usr/local/apache/logs/rewrite_log" RewriteLogLevel 1 RewriteRule ^/local/ - [L] RewriteRule ^/icons/ - [L] RewriteRule ^/~(.*) - [L] RewriteRule ^/cgi-bin/ - [L] RewriteRule / http://erebus.ait.ie:8080/zope/VirtualHostBase/http/erebus.ait.ie/VirtualHo… [P] This gives me access to the Plone site in response to the URL http://erebus.ait.ie, but it doesn't display correctly: I get a very basic html page, not Plone in all its glory. As an alternative approach, I tried RewriteRule / http://erebus.ait.ie:8080/zope/erebus_plone/VirtualHostBase/ [P] This gives me Plone in all its glory, but with a 404 error message: not found. I've been reading any relevant material I could find (searched zope.org, read the relvant section of the Zope Book) and I have to admit I'm not sure how to correct this problem - in fact, I'll admit I don't fully understand the syntax in the RewriteRules. Possible options: 1. Put the Virtual Host Monster into Zope's Root folder? The reason I'm not doing this is that on a previous attempt I lost access to the ZMI. 2. Add a SiteRoot object into the Root folder? zope folder? Again, I've tried this, and have had problems getting access to the ZMI. I'd appreciate it if someone could point me in the direction.

Reg External methods
by gknath2003＠dacafe.com 18 Jun '04

18 Jun '04

hi all, i am new to zope and am using external methods to call an exe file( say for example winword.exe). i also need to pass vlaues to the same. but whenever i invoke(thru DTML) or test the external method from inside zope, i can see an instance of the application getting started (in the process tab of the task manager) but am not able to see the application window (eg., in our case, a blank word doc) I am using winxp. Is this a problem with Zope or the operating system? If the problem is with zope, what settings do I need to change? Thx for the help. Cheers, Gk ----------------------------------------- This email was sent using http://cafemail.edacafe.com .

ANN: VarImage 2.3.2 Released
by Terry Hancock 18 Jun '04

18 Jun '04

Version 2.3.2 includes the large cache-optimization patch written by Eric Pollman which reportedly can improve performance by 10X or more in certain test conditions. I have tested it on Zope 2.5.1 and Zope 2.6.4 (on FreeBSD and Debian Linux platforms, respectively), but it probably works on later Zopes and any platform on which PIL is available. This also fixes a bug with handling width and height attributes, should they be set to strings instead of ints, which avoids some annoying editing problems. Get it from the Narya project at SourceForge: http://sourceforge.net/projects/narya-project Cheers, Terry From the README.txt file: VarImage 2.3 VarImage means "variable image". It provides a way to make on-the-fly modifications to an image in Zope simply by referring to the correct URL. [...] Syntax The URL-command is parsed as a chain of "operations" to be applied to the original image, separated by "." (period). Each operation is specified as an "operator", followed by zero or more "arguments", separated by "_". Arguments and operators must be composed of only letters and numbers ([A-Za-z0-9], note that "_" and "." are not legal because they are used as separators). Other than the fact that floating point values have to use "o" (the letter "o") instead of "." for the decimal point, this works well. Colors are represented by strings, usually as hexadecimal codes, with a prefix of "x" and 6 hexadecimal characters. Component images may be referred to by their unadorned Zope ID, so "myimage/components/mycomponent" is simply "mycomponent". Note that, to be useful, you have to use only letters and numbers in the name of components. Each operation is applied in sequence, to the result of the previous operation, and then the final result is returned. Examples If you have a VarImage "shinobu_jpg", you can get it in an exact size of 100x100 (regardless of the original aspect):: shinobu_jpg/s_100 or 100x50:: shinobu_jpg/s_100_50 or you can thumbnail it into a 70x50 space (the longer dimension will be determined by the specified limit, while the smaller is determine by the image aspect ratio -- i.e. the image will "fit" into the available 70x50 space):: shinobu_jpg/f_70_50 or you can set the horizontal or vertical dimensions:: shinobu_jpg/h_85 shinobu_jpg/v_100 (The above examples are converted from the Version 1 docs). You can also convert the image to PNG or GIF format:: shinobu_jpg/tn_100.png shinobu_jpg/tn_100_200.gif And do color effects, such as black-and-white:: shinobu_jpg/bw or color-multiplication:: shinobu_jpg/mult_x0e5f00.png shinobu_jpg/bw.R.gif Special Commands For a help page with a complete list of all currently understood operators, use:: shinobu_jpg/help If you need to clear the cache and start over for some reason (this is necessary a lot when you're writing a new plugin):: shinobu_jpg/clear_cache [...] How It Works VarImage inherits from Zope's Image and ObjectManager types, so it is an image that also acts as a folder. The folder contains a Temporary Folder named "cache". When you query for a modified image, it first checks to see if the cache already contains the image. If so, it returns that. Otherwise, it uses Python Imaging Library to generate the image, and stores the result in the cache. [...] Writing Plugins It is now trivial to add a plugin operator to VarImage, and you do not need any understanding of Zope to do this. You will need to understand how to manipulate and process images in Python. [...] Author and Licensing Terry Hancock wrote VarImage for Anansi Spaceworks.

I am suddenly receiving mail from the zope list again
by Max M 17 Jun '04

17 Jun '04

I have unsubscribed from the zope list some weeks ago (using gmane instead). But suddenly I am receiving mail from it again. Is there something I have to do or will the problem magically be fixed for me? I assume others might have the same problem. -- hilsen/regards Max M, Denmark http://www.mxm.dk/ IT's Mad Science

Since the cache is per-thread, it can sometimes be better to run fewer threads with bigger caches. You could try lowering the number of threads to 2 and doubling the cache size. This may be better than 4 at 15000, but it depends heavily on your application and the load it experiences > I am using ZEO with one ZEO client, running on same server. > > I'll try using 15,000 cache setting. This is what I now have in my > zope.conf: > > <zodb_db main> > cache-size 15000 > <zeoclient> > cache-size 20000000 Try upping the client disk cache size as well. This looks like the default (20MB) which is quite small. I would probably multiply this by 10-30x. An indication for a too small ZEO client cache is many "Cache flip" log messages from Zope. -Casey
