[Zope-dev] External method
This is not a strictly zope related question but it is zopeish :) In an external method I need to call an executable and capture the output it generates. This executable however needs to connect to a running X Server. I used the popen2 command but it returns with the obvious error : "theprogram : cannot connect to X Server". So how does one tell a program to attach to a X server? Any help would truly delight me Roché ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )

Because both are quite capable of crashing a thread (maybe the whole thing), with poorly written regex expressions.

[Zope-dev] Performance enhancements, ZCatalog
ZCatalog enthusiasts, I just upgraded our zope installation from 2.1.6 to 2.2.4, and the ZCatalog performance is aweful. Can someone remind me what the command for speeding up python on a dual processor machine is? python -T? I'm looking for any way to speed this up. I have a text index with 47,000 objects and a search takes about 15-18 seconds, hardly what we were used to. It used to be 2 second tops. My company is being shopped around and if we get bought I want to convince the new company that Zope and python and Linux are the way to go. I need all the help I can get.

[Zope] [Zope-dev] [BUG] Background processes interfere with Zope's HTTP responses
Today was again a hard Zope day.
Did you ever hear, that usually (i.e. if you do not do special
things) Zope renders a complete page before it starts
sending the result back to the client.
This implies that you should never see only half of a page.
I heard it and I saw the code that does it.
Therefore, I was convinced that this were really the case.
Then our client phoned:
He visits a page that allows him to generate a
newsletter. When he presses the "generate newsletter button",
a result page is build that tells him that the newsletter
is being generated and send is a few minutes.
He reported, that this response page is build only
half, then stops, to be completed only half a minute later,
at the same time when the newsletter arrives.
The effect is reproducible. If newsletter generation
takes longer, he must wait longer for the page to complete.
He is convinced that we generate the newsletter synchronously
and let him wait until the generation is complete.
And he is angry.
I know, that the newsletter is generated in a background
process, started in an external method with:
os.system("gen_newsletter ")
I try to reproduce the behaviour in our test environment
and fail. I do not have to wait, until the newsletter
generation finished. Then, I use the official service
URL and see, I observe the same behaviour.
The difference: in the test environment, the browser
connects directly to ZServer; with the official
URL, it connects via a proxy.
Puzzling!
What happened?
The background process inherits Zope's open file descriptors.
Among them are all currently open HTTP request sockets.
The process keeps these sockets open until it finishes.
There are two HTTP modes:
1. single request mode
a new TCP connection is created for each HTTP request,
the request is completed, when the TCP connection
is closed.
2. multi request mode
several requests share a single TCP connection.
The "Content-Length" HTTP header allows
client and server to determine the request boundaries.
That means: when a client uses the multi request mode,
everything is fine. Clients, however, that use
the single request mode wait until their connection
is closed and can observe serious delays.
These delays may be very difficult to explain, as
the background process not only delays its own
request but may delay arbitrary other requests
that happen to be served at the same time.
How to fix the problem:
There should be a (file) control "CloseOnExec", that tells
Unix to automatically close the file like object upon
an exec.
ZServer should probably use it on each of its sockets.
I can not see a serious application that should have
direct access to ZServer's HTTP request socket.
I will soon file a bug report into the Collector.
Dieter

Re: [Zope-dev] 'Subclassing' another product
Hi Morten,
There are two ways to subclass products. You can use straightforward
Python subclassing:
e.g.,In your custom Product.. here is an example from Zwiff:
import Products.PythonMethod.Guarded
from Globals import HTMLFile, MessageDialog
from App import Common
manage_addZwiffForm = HTMLFile('addForm',globals())
def manage_addZwiff(self, id, title, params, body, REQUEST=None):
"""Add A Zwiff to a folder just like PythonMethod..
"""
it = Zwiff(id, title, params, body)
self._setObject(id, it)
return self.manage_main(self, REQUEST)
def handleMovieOutput(movie, RESPONSE):
fname = tempfile.mktemp()
movie.save(fname)
f = open(fname)
s = f.read()
f.close()
RESPONSE.setHeader('Content-type', 'application/x-shockwave-flash')
os.remove(fname)
return s
class Zwiff (Products.PythonMethod.PythonMethod.PythonMethod ):
meta_type = 'Zwiff'
def makeFunction(self, compile=0):
from Products.PythonMethod.Guarded import GuardedBlock, safefuncs, theGuard
if compile:
self._checkCBlock(GuardedBlock)
if self.errors:
raise "Python Method Error", string.join(self.errors, '\n')
return self._newfun(compile, {'$guard': theGuard},
__builtins__=mysafebin, _=safefuncs)
So the class Zwiff is a subclass of PythonMethod. Look at Zwiff for the full
source: http://www.zope.org/Members/sspickle/Zwiff
Or you can create a ZClass that subclasses from a 'base class'. To do
this you've got to register the base class with the ZClass machinery
(e.g., here is the code for ZCVSMixin that does this ZCVSMixin
is a base class... CVSFolder is a full blown product that happens
to be a subclass of ZCVSMixin... )
import ZCVSMixin
import CVSFolder
__doc__ = ZCVSMixin.__doc__
__version__ = ZCVSMixin.__version__
def initialize(context):
context.registerClass(
CVSFolder.CVSFolder,
constructors=(CVSFolder.manage_addCVSFolderForm,
CVSFolder.manage_addCVSFolder),
icon='fish.gif',
)
context.registerBaseClass(ZCVSMixin.ZCVSMixin)
does that help?
take care,
-steve

Re: [Zope] Newbie question: adding a tinyTables objec
If a product contains only a Help object, it means that the product is a Python Product, rather than a ZClass Product. No broken box in front of the Product name, hmm... Does Zope raise any errors when you try to start it? Try to remove the whole TinyTable folder and reinstall it again after having had a second look in the INSTALL or README docs. If there are any. Don't give up my friend! No, that's the problem. The icon isn't a broken box, but a regular product icon. Clicking on the link shows that there's one item in TinyTablesPlus, a Help document; when I open that, it tells me that there are no items in TinyTablesPlus. So Zope seems to be seeing the product, but not adding a TinyTable to the list of Available Objects. Is there some setting that I need to change? Sorry to be so dense. It's tantalizing to have all this power so close at hand, and not be able to access it. Richard At 10:25 PM + 12/18/00, Peter Bengtsson wrote: Go to the Control Panel and click on Products.

[Zope] Weired catalog_object problem in python product
Hi, I read about ZCatalog been _the_ method of managing and searching objects in the ZODB. So I decieded to do searches and lists of object using ZCatalog. After reading all how-to's/API-doc about ZCatalog, a lot in mailings lists and studying a lots of code (ZDiscussions, Squishdot, PTK) I tried to use ZCatalog the proper way. But there is one problem I could not solve for about 8 hours of work. A short description of what my code does: I have three classes (NewsManager, NewsItem and ContentFolder) caring about news items. If I am creating a news item, it's object gets saved and cataloged in the content folder (the content inherits from ZCatalog). The NewsManager object responsible about creating the news item is named news and resides in the same directory as the folderish content object does. So the directory structure is: /orgname/content (content object, inherits from Products.ZCatalog) /orgname/news(NewsManager object, inherits from OSF.Folder) Now the problem (for a step by step description see below): The news items are correctly created in the content folder. But the item is cataloged as it would reside in xxx/news/content (which does not exist). I use self.absolute_url(relative=1) (called by __uniqueCatalogId()) to generate the catalog id (see manage_afterAdd below). It seems (for me) that some aquisition magic is going on. Later when I edit the news item (manage_editNewsItem called by manage_editNewsItemForm) there appears an additional catalog entry with the id xxx/content. Now there are two catalog entries for one news item. If I delete the news item manualy using the zope management GUI one of these catalog entries will be deleted only. Hints: 1) The following status message appears in zopes error log after having edited /orgname/news/content/20001219_news22: 2000-12-19T11:10:41 ERROR(200) Catalog uncatalogObject unsuccessfully attempted to uncatalog an object with a uid of /orgname/content/20001219_news22. 2) It seems for me that the magic resides in absolute_url(). Does somebody know about a solution of this problem or have an additional hint about generating catalog id's (it's a requirement for me to have the /orgname/-info in the catalog id!)? I'am a Zope newby, so forgive me errors that are obvious. System and SW-Versions: - WinNT4 SP6 US - Zope 2.2.4 started manualy Remark: It's all programmed in Python because I don't like GUI programming tools (click, click, ... :-( ). So I implement all logic in python (as a Product). what I've done in the zope management GUI Create a news item: http://localhost:8080/up/news/manage_addNewsItemForm View Contents (content folder): http://localhost:8080/up/content/manage_main -- item 20001219_news22 is listed and links to: -- item 20001219_news22 is listed and links to: http://localhost:8080/up/content/20001219_news22/manage_editNewsItemForm View Cataloged Objects (content folder): http://localhost:8080/up/content/manage_catalogView -- content contains 1 record(s).

Re: [Zope] ZCatalog raises index out of range exception error
I believe I saw this error when trying to use the Catalog in a SiteRoot-ed folder... Me too :-( And me too. The most irritating Zope bug for me. No solution, sorry ;) :-( Partial solution: at something like 2:00 AM delete your SiteRoot rule, reindex with ZCatalog and create this rule again. Searching works (although I needed to edit the paths found a bit in the form responsilbe for search results presentation). I can imagine writing the script (XMLRPC?) which would do it from the cron job - although I have not yet found spare time (I still think someone will do something with this nasty bug). -- http://www.mk.w.pl / Marcin.Kasperski | Dokumentacj kodu warto wygenerowa: @softax.com.pl | http://www.mk.w.pl/narzedzia/narzedzia_gendoc @bigfoot.com \ ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )

[Zope] Re: [ZWeb] Feedback
Hi Martin, I moved this thread over to the Zope mailinglist; the Zope-Web mailinglist is intended for discussion related to the Zope.org website itself. You'll get more feedback on the Zope mailinglist. On Tue, Dec 19, 2000 at 05:41:34PM +0100, Edwin Martin wrote: The last couple of months I developed a dynamic website in Zope. You can take a look: http://www.joods.nl/, but be warned: it's Dutch. Cool, I always like to see more Dutch websites. I never really convinced my colleagues at my previous employer about the advantages of Zope; they were/are entrenched in the Java point of view of the world. I did manage to convince my COO though, who is now starting his own Zope-driven business. You may want to tap into the Dutch Zope community as well; see http://zll.zopatista.com:9673/ I used Zope 2.1.6 with python 1.5.2 on Debian Linux 2.2r2. While developing in Zope should be fast, unfortunately, it was not. Some minor things, which would be no problem in any other language, took me hours to do in Zope. Here is a list. I'm sure some things are already solved in the newest version of Zope. I'm posting this list not to offend, but to help you improve the system. Feedback is always welcome, please keep it up. Indeed, many issues are already solved in the current release of Zope. Note that Debian Woody has the most recent version, 2.2.4, packaged as a .deb distribution. You don't need to upgrade to Debian Woody to be able to run this; you can download the distribution and use dpkg --install manually: http://packages.debian.org/unstable/web/zope.html 1) When I make an error in an DTML-page, all my changes are lost! This is really frustrating. And unnecessary. This is more a browser cache issue, where the browser (esp. Netscape, IIRC), would re-retrieve the edit form when pressing the Back button. Try tuning your browser cache parameters. 2) Variables with a minus-sign in it! Who came up with that? Now I have to write dtml-var expr="_['sequence-length'] 10". Yep, they are lame. They are a remnant of the times before expressions in DTML where added, something that many regard as a mistake. You can use dtml-var to create an alias of such variables. Another option is using external methods to deal with the coding of these areas; usually you are dealing with logic, not presentation, and that is better suited for Python code. DTML should only be used for presentation. In Zope 2.3 you'll be able to use Python Script objects for this as well, giving you TTW python code. 3) sequence-start is only valid at the beginning of dtml-in. This really limit it's use, for example to print a 'previous'-button on the bottom of the page. You can use a seperate dtml-in construct for that, using the 'previous' or 'next' attributes. 4) Zope has an Image object, but you can't ask for the width and height (which should be trivial). You can actually. In DTML: dtml-with imageThis image is dtml-width; wide/dtml-with 5) You can use dtml-var myImage to show an image. But it's not possible to set border=0, which is also trivial. Use: dtml-var "image.tag(border=0)" The tag method generates an img tag for you, with the extra attributes inserted. You can also use this to remove or replace the autogenerated alt, width and height attributes, or scale the width and height values. 6) I invested some time to learn ZClasses. Only to find out the query-features are very poor, which made it useless to me. Now I only use 'real' databases. Query features? Could you elaborate? 7) The dtml-let tag is nested. So how can I remember a value I discovered in an dtml-in loop? I am not sure what you mean here. Within a dtml-let tag the surrounding namespace is still available, including the dtml-in loop values. 8) I made a big HTML-form to post and edit articles. To make a form to edit an article, I used: dtml-in getArticle form..Big form here/form /dtml-in But how can I use the *same* big form for a new article? I think putting the form in another file (as I did) is not the right solution. Why not? Putting the form into a seperate DTML Document or Method would make the form a reusable object, which to me looks like the right thing to do in this case. 9) I consider this a bug: dtml-var expr="objectValues()[0]" gives the value HTML-quoted. Very strange. I can't reproduce this. What object is returned by objectValues()[0]? (objectValues returns an array of object instances, of which you select the first, which is then 'represented' in the output stream). 10) It's pretty hard to use a checkbox in a form. Browsers don't submit unchecked checkboxes, which result in Key-errors. Writing wrappers for every checkbox is an ugly way to solve this. Use a hidden value with ':default' appended to the name. This makes the variable alwas available, browsers always send hidden fields, even if the value is empty: input type="hidden" name="a_checkbox:default" value="" input type="checkbox"

RE: [Zope] Zope's . vs _ unsolved issue (Re:To retrieve properties from a dtml document) document)
What kind of content is it that you are uploading to Zope, and what is your workflow? As someone working in the news industry with several online newspapers and also fairly experienced with Zope and content automation, I might be able to make some suggestions that might help you out. Zope has some weird issues with namespaces and syntax that sometimes clash with Python's. That said, I think that things are constantly improving. Perhaps _['identifier'] solves your problem, at the slight cost of being just a bit kludgy. Do you use Zope for your staging server, or just for your live site? There might be ways to use it at both ends, integrate with dreamweaver, and bypass using wget... From the sounds of it, you are using zope as the back end to an "editorial-system" workflow using Dreamweaver, but you are not taking advantage of most of Zope's features that facilitate content management. If I was familiar with your workflow, I'd be happy to provide advice if I could be of any help.

You still have given no cogent reason for using Zope. If you have only, or predominatly static content, you are paying a huge overhead penalty. If you have mixed static content and dynamic content, use apache and ProxyPass to front-end the dynamic content, and apache to serve the static content. Then you have no conversion worries at

Or you could use "_['id']" in place of "id". Which does exactly the same
as the let tag does in the above statement, ie a lookup in the namespace
and then calling it if it is a method. Example:
dtml-with your_object
dtml-call "REQUEST.set('id_name', _['id'])"
/dtml-with
This kind of hoopjumping is exactly why in Zope 2.3 you now can use the
method 'getId()', which will hide the confusion for you. From Zope 2.3
onwards, *always* use getId():
dtml-with your_object
dtml-call "REQUEST.set('id_name', getId())"
/dtml-with
or:
dtml-call "REQUEST.set('id_name', your_object.getId())"

You don't need to delete your SiteRoot. You can use one of techniques
described in SiteRoot docs to suppress it within particular request.
I use trick with phantom folder, call it 'Z'.
So my AccessRule looks like:
Is there a path, and does it start with 'Z'?
dtml-let stack="REQUEST['TraversalRequestNameStack']"
dtml-if "stack and stack[-1]=='Z'"
Get rid of 'Z': dtml-call "stack.pop()"
Put it back logically: dtml-call "REQUEST.setVirtualRoot('Z')"
dtml-else
Is the first-level domain 'hotsite.com'? Ignore sub-domains and port
number.
dtml-if "_.string.split(_.string.lower(_.string.split(HTTP_HOST,
':')[0]), '.')[-2:]==_.string.split('www.hotsite.com','.')[-2:]"
Add physical root:
dtml-call "REQUEST['TraversalRequestNameStack'].append('hotsite')"
dtml-call "REQUEST.set('SiteRootPATH','/')"
/dtml-if
/dtml-if
/dtml-let
In my SiteRoot, I have all properties left blank.
When I access my server using URL like www.myserver.com/Z/something, then
SiteRoot is turned off.
With this solution, your site may be still accessible to customers, while
you are working without SiteRoot (i.e. cataloging objects).

[Zope] Newbie: manage_changeProperties and wrong permission
I need to call manage_changeProperties but Zope refuses to accept my
authentication.
There's a "Fir" class with two subfolders ("cz" and "en"). The
subfolders contain identically named properties: lst_name and lst_text.
These properties are then displayed using simple acquisition:
http://...instance/cz/display and http://...instance/cz/display, where
"display" is a method of Fir class that calls dtml-var lst_name.
Simple.
To change the lst_name and lst_text properties thru the web, I created
simple form and a method within the Fir class. This is the
changeLST_form:
dtml-if expr="REQUEST.has_key('lst_name_new')"
dtml-call
expr="manage_changeProperties(lst_name=REQUEST['lst_name_new'])"
h1The property 'lst_name' has changed/h1
dtml-else
h1No properties were changed/h1
/dtml-if
dtml-if expr="REQUEST.has_key('lst_text_new')"
dtml-call
expr="manage_changeProperties(lst_text=REQUEST['lst_text_new'])"
h1The property 'lst_text' has changed/h1
dtml-else
h1No properties were changed/h1
/dtml-if
Unfortunately, authorization fails when this script is supposed to run:
"You are not authorized to access manage_changeProperties."
I'm running this script as a "manager" defined at Zope root, in other
words with the default setup. Normally I can do anything in Zope with
this authorization.

Hi Deiter,
Hmm.. I just tried this with my highly experimental product
(LocalProc 0.0.1) and I didn't observe the same effect that you did
behind my Proxy Server. (I normally run with Rewrite... but when I got
your note I tried ProxyPass and it worked on the first try.)

Anyway... I ran 'sleep 20' as my local process (I checked the
'background' button on my product) and the web page returned
immediately, but the process ran on in the background as I wished. The
main difference I see between what you are doing and what I do.. is
that I redirect stdout and stderr so that my subprocess has no open
files shared with the parent process.. anyway.. you might try this to
see if it suits your needs. Lightly tested on FreeBSD only.. but any

hi all i have a zope site that uses ZEO, runs behind apache and on RH6.x what puzzles me is that only *one* zserver thread is alive after some time and it consumes most of the processors cycle. the top snapshots are at the bottom of this message anybody got any ideas why this happened? i think this may have contributed to the slow response to the site. if i restart zope, everything works dandy... until some time when only one thread is used, instead of 4 what are others seeing? is it my codes? thanks 8- ZC1 4515 nobody 0 0 99.2M 99M 1592 S 0 4.1 2.5 183:37 python 4537 nobody 0 0 99.2M 99M 1592 S 0 0.0 2.5 0:07 python 4538 nobody 0 0 99.2M 99M 1592 S 0 0.0 2.5 724:16 python 4539 nobody 0 0 99.2M 99M 1592 S 0 0.0 2.5 751:47 python 4540 nobody 0 0 99.2M 99M 1592 S 0 0.0 2.5 735:11 python 4541 nobody 0 0 99.2M 99M 1592 S 0 0.0 2.5 749:27 python 4542 nobody 0 0 99.2M 99M 1592 S 0 0.0 2.5 741:45 python 4543 nobody13 0 99.2M 99M 1592 R 0 94.0 2.5 1734m python ZC2 4348 nobody 0 0 102M 102M 1828 2 S 2.1 13.5 214:33 python 4350 nobody 0 0 102M 102M 1828 2 S 0.0 13.5 0:10 python 4351 nobody 0 0 102M 102M 1828 2 S 0.0 13.5 398:08 python 4352 nobody 0 0 102M 102M 1828 2 S 0.0 13.5 407:02 python 4353 nobody 0 0 102M 102M 1828 3 S 0.0 13.5 406:32 python 4354 nobody 0 0 102M 102M 1828 3 S 0.0 13.5 392:10 python 4355 nobody14 0 102M 102M 1828 2 R95.5 13.5 4712m python 4356 nobody 0 0 102M 102M 1828 2 S 0.0 13.5 388:41 python Z3 18567 nobody 0 0 73652 71M 1724 S 0 4.4 14.2 273:56 python 18571 nobody 0 0 73652 71M 1724 S 0 0.0 14.2 0:44 python 18572 nobody 0 0 73652 71M 1724 S 0 0.0 14.2 42:03 python 18573 nobody 0 0 73652 71M 1724 S 0 0.0 14.2 63:13 python 18574 nobody19 0 73652 71M 1724 R 0 91.2 14.2 6144m python 18575 nobody 0 0 73652 71M 1724 S 0 0.0 14.2 47:54 python 18576 nobody 0 0 73652 71M 1724 S 0 0.0 14.2 57:10 python 18577 nobody 0 0 73652 71M 1724 S 0 0.0 14.2 57:13 python -- http://www.kedai.com.my/kk http://www.kedai.com.my/eZine if you SMELLL ... what the Rock is cookin ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )
[Zope] Re: Network hangs
Apache sit's on port 80 w/all static pages Zope is now on port 8080 until the move is completed (then it becomes primary on 80). So I was able to narow it down. With Apache now stopped, Zope is running great. I assume there was some arguement between Zope and Apache about who controlled what (?) but with Apache stopped it's solid. Anybody have any ideas? Should I scrap Zserver and do the pcgi patches? (This machine will eventualy host 2 domains so I may have answered my own question). Input please...

[Zope] newbie zcatalog
Please consider the following code fragment:
dtml-if expr="REQUEST.REQUEST_METHOD=='POST'"
dtml-call "REQUEST.set('ts', ZopeTime())"
dtml-call "REQUEST.set('id',_.str(_.int(ts)))"
dtml-call "postings.catalog_object(REQUEST.postingtext,REQUEST.id)"
Classified:p
dtml-var "REQUEST.postingtext"
p
On execution, REQUEST.postingtext is displayed as expected. An object is
placed in the Zcatalog postings as determined by using manage. However,
clicking on the underlined id of an object in manage yields a traceback
ending in an object not found. It is sort of expected to display "Hello
World".
Please advise.
