accessing DTML variable namespace outside DTML
by Service Informatique CHSR 02 Apr '99

02 Apr '99

Hello. I just posted this to the collector. What do you think? -----------------8<------------------------- DTML variable namespace is not available from eg External Methods, ZSQL Method, etc... Only the variables defined in REQUEST are available. Because of this feature,  construct are useless when used in conjunction with Z* Methods. For example, in   ...   cookedvalue is not available from query, even if the name "cookedvalue" is among the ZSQL Method parameter. However,   ...  works great. But it is sometimes indesirable to leave the variable 'cookedvalue' in the namespace. I had to patch my Zope to implement REQUEST.unset, but I'd like to use as few patches against pristine Zope as possible. Also, a DTML Method calling an External Method (or ZSQL Method, or whatever method) that is evaluating another DTML Method (or ZSQL Method, or whatever method) often do not render as expected because only the variables stored in REQUEST are kept. I suppose this feature would require a rewrite of the REQUEST variable handling, causing it to also 'carry' the current DTML namespace along with it. Anyway, I think it would be useful. It would also allow me to simplify some of my code :-) -----------------8<------------------------- Regards, Jephte CLAIN Service Informatique CHSR

It is really a very simple server based on CGIHTTPServer. ZServer *does* support and supports it rather well. Checking out Sam's Medusa site http://www.nightmare.com/medusa.

Hyperfiction Questions
by Christopher.Abraham＠cio.treas.gov 01 Apr '99

01 Apr '99

(Sorry about sending the previous with the Digest Appelation) Hi: I am a newbie, and am only using Zope like SSI. I have experience with Cold Fusion and PHP3 and need to do the following on my little hyperfiction site, COELABORATION.COM. I have collected a main file of content that looks like this: << - - - - - 8:41) Ginny Little 06-JAN-98 18:26 no downer, just a cycle, a circling round, a pause for breath, a look at shadows in the light, offering contrast, offering calm resolve, as people die on skis on slopes i have traversed, so i pause, and i wonder a bit, and i don't say much-the silence comforts and words capture nothingness. - - - - - 8:42) Katherine Blanke (KAT) 06-JAN-98 23:07 Late at night, on break from the pile of homework that still eludes me...had a glimpse of the "adult world" today in the registering of college. Funny how when I reach the end of a stage, I always look to the next steps as being wonderful and transforming. Funny, isn't it... Late at night, the only thing alive is my mind and my writer's voice, sometimes a whisper at the back of my mind, other times a shout I turn frantically for but no one else hears. House settling, vent rattling, clock chiming the hour, quarter after, half-hour, quarter to...every fifteen minutes, part of my life is gone away. I used to waste away the hours, no one to share them with, why do anything? Old habits die hard, as I now have many people, I still sit alone when they are not there. alone, together, flip-sides of the same mirror. When you are with people, you long to belong, when you are not, you still wish to be with them. Tick-tock....tick-tock....tick-tock....mind shuts off and soul uncovers the cloth... Sometimes, I just want to dance. I want my feet to jump and sweep along the old carpeting of the confined space that is my living room, feeling my arms stretch out and my legs twirl me around and around. I want to move my arms and legs and twist about and feel graceful, feel immortal, with my dreams hanging in the ceiling and my fallings-out in the basement, forgotten for the moment. Sometimes... @!KAT - - - - - 8:43) Ginny Little 07-JAN-98 12:35 i think about somedays. someday i will... - - - - - 8:44) Kathy Madden 08-JAN-98 19:56 Dance, dance, dance....those who feel the desire should never repress it.

Re: [Zope] Zope+Virtual Domains
by Anthony Baxter 01 Apr '99

01 Apr '99

I haven't seen a reply to this... ZopeHTTPServer (or ZServer, which is replacing it) certainly doesn't seem to have any support for virtual domains. However... they bind to the wildcard address (listening to all addresses on a box), so there's no reason you couldn't do _some_ sort of switching based on the IP, using the Host header from the request in your DTML. cc'ing in zope-dev here: Hm hm hm. I wonder if it would be worth adding a hook to ZServer, to make it look for a Host: header, and prepend something to the request URL it passes to zope? Eg. hostmap = { 'www.zope.org': '/Zopesite/', 'www.elvis.com': '/elvis/' } thoughts? (anyone know if ZServer will appear in public CVS anytime soon?)

Debugging Tip
by Amos Latteier 01 Apr '99

01 Apr '99

Maybe you know this one already but I didn't. Did you know that you can fire up Python and import Zope's Main module to get access to Zope's objects from the comfort of the Python prompt? 1. cd to lib/python, this will make things easier, since you won't have to add lib/python to your sys.path. 2. start Python (if you're using a binary of Zope, you may want to use Zope's copy of Python) 3. import Main 4. The Zope app object is Main.app 5. From there you can get at any Zope object. 6. Some objects may be ghosts and will look empty when you do a dir on them. To load them from the object database, try to access one of their attributes. 7. If you want to make changes to the database don't forget to call get_transaction().commit() to commit your changes. If you really want to mess up your Zope install this will let you do it in style ;-) Of course you wouldn't be considering this unless your broken Product already messed things up, so what do you have to lose? Also, don't forget about the Zope debugger which is a more controlled way to get access to Zope internals. Have fun! -Amos

NT Service

I'm suprised noone could suggest an easy way to run Zope as an NT Service, but this is so useful I thought it would be worth writing. The script below uses the service support from the win32 extensions package, at http://www.python.org/windows, although I have not tested it with the binary distributions. Hopefully this is useful to someone else too, Toby Dickenson ---- port=80 swhome='D:/Progra~1/Zope' python_cmd='d:/progra~1/python/python' import sys import os import win32serviceutil import win32service import time import thread import string sys.path.insert(0, '%s/lib/python' % swhome) sys.path.insert(1, '%s' % swhome) import ZopeHTTPServer from ZPublisher import Client try: access=string.split(open('%s/access'%swhome).read(),':') zope_admin_user_name=string.strip(access[0]) zope_admin_password=string.strip(access[1]) except: zope_admin_user_name="" zope_admin_password="" def run_zope(): args = ['-p', str(port), 'BOBO_DEBUG_MODE=1', '%s/lib/python/Main.py'%swhome ] try: ZopeHTTPServer.main(args) except SystemExit: pass def stop_zope(): url="http://localhost:%d/Control_Panel/manage_shutdown"%port f=Client.Function(url) f.username=zope_admin_user_name f.password=zope_admin_password try: f() except: pass class ZopeService(win32serviceutil.ServiceFramework): _svc_name_ = "OZope" _svc_display_name_ = "Zope" def SvcStop(self): print "Stop request received" self.ReportServiceStatus(win32service.SERVICE_STOP_PENDING) # need make http rpc to zope in a different thread since we need to return from # this stop request sooner than the rpc will complete.

Ok, maybe I was misunderstanding what Pavlos' code was intended to do (probably because I didn't read it, just glanced at it)... try this... >  >  > (The 'PARENTS[0]' should be unnecessary. What I had suggested was PARENTS[-1] as an alternative method of globalizing the unique ids. That is, with PARENTS[-1] the same code could be used in five different directories, and each id would be unique in the flat namespace inclusive of all five. This would look like: >  >  > Howard C.
