Yes, thats a common problem - true HTTP-headers always
override these meta headers. Unfortunately file based
approach leaves you and most tools with the meta tags
to transport encoding accross different file based
tools. In Zope you should simply:
dtml-call expr=RESPONSE.setHeader('content-type','text/html;
charset=utf-8')
somewhere in the header and probably skipp the meta
tag (or have it at least the same content)

OK, mod proxy and such may change some headers in it, but the Content-Type's charset? The charset is about the HTTP response body, which is surely created inside Zope. Yes. Its entirely Zopes job. And if you are using pure Zope, you need to set the header in the publish process, e.g. with a python script or something you use for default display. Also you need to set a property manage_page_charset in zopes root to be able to use that encoding in ZMI too. This way you arent storing unicode - only utf-8 as you want to display it.

Well, ZSQL Methods always return result sets, never strings. The restult set is an object which works similar to a list with result objects, each result object having attributes which correspond to column names of your query. The result objects have a method dictionaries() which in fact return the data as regular list with dictionaries for the rows (easier to look at if you see their string representation) so what you probably want goes like this: result=container.getUserLevel(uname=user) if result: userlevel=result[0].userlevel else: userlevel=somedefault # or raise error or whatnot the if result: idiom handles the fact the query might not return any result. It is true however if you get at least one row. result[0] addresses the very first row of the result - which must exist in a non empty result set.

Next thing you would do is to set a lifetime of the cookie maybe in the source of cookiecrumbler or ExUserFolder.

[Zope-dev] DBTab/ZEO configuration in Zope2.7 beta1
Hi, looking thru code, examples and documentation, it seems DBTab is included into Zope2.7. Now how to configure it? Should I use a dbtab.conf file as it was with 2.6? The mkzopeclient.py with -z option just builts a custom_zodb.py which does not seem to be very 2.7-alike. Shouldn't that configuration not be in zope.conf? I cannot find relevant tags for the zodb_db tag. Are there any places I could look into for enlightement?

Re: [Zope-dev] DBTab/ZEO configuration in Zope2.7 beta1
Hi Chris,
thank you. By the time I got it working when I first
used filestorage, bootet zope so it created all folders
as it wants and then stop zope and use that Data.fs
for ZEO. Then I was able to mount the zeo as /
I'll investigate this further and provide the examples.
For now even the fallback seems to work.
Storage type temporary seems to not mentioned anywhere,
but I'll test this too.
Kind regards

This is because the default is to mount a temporary storage at

Something like this (untested) as an additional zodb_db entry should
work:
zodb_db temporary
temporarystorage
name sessions

mount-point /temp_folder

Hi Jaroslav,
perhaps you want to use dtml-with rootfolder ...navigation.. /dtml-with

Rootfolder could be the object you want to be the root (of course)
or in case of ZopeRoot, you get it via REQUEST.PARENT[0]
However, before beating the dead horse, you should consider
replacing your routine with a python script, which could
also use ZCatalog in place of ObjectValues() - this saves
Memory and time since not all Objects have to be activated.
This approach would also help you to go the way from
DTML to ZPT which is recommended.

image.gif
/folder11
/folder111
/folder112
/folder12
/folder2
/folder21
All three DTML* contains same code:
dtml-in objectValues('Folder')
dtml-var idbr
/dtml-in
img scr=dtml-var absolute_URL/image.gif
Imagine what is doing that DTML Document or DTML Method are called from
inside of /folder11. DTML Document make bad, but still functional (due
acquisition) link to image.
But DTML Relation will still give that same output, independent from where
you call it:
folder11
folder12
img src=http://domain/folder1/image.gif;
Output is still independend from where you calling that DTMLRelation and
give you right URL paths (relative or basolute).
I think that DTML Relation (or you can call it better) should be very
usefull, for example:
1. for navigation structure when you want to have constant navigation
buttons what are dynamically generated from folder structure that have
strong changes in any folder names
2. for image menus, where it give right path to images folder instead of
acquired images
etc. (I now, you can specify path with dtml-var BASE1/images/image.gif)
Many thanks for your kindly attention.
If it have simple solution by standard DTML code, let me know that code,
please.

Oktober 2001 12:11 +0200 Itamar Shtull-Trauring [EMAIL PROTECTED] wrote: Actually, this brings up this idea I had - Zope should replace medusa with Twisted. Why, you ask? 1) Twisted separates transport from protocols, and the event loop it uses is extendable and generic. That means: - It can run on Jython (using threads, someday with java.nio), and it can be integrated with the Tk and GTK event loops. - Your protocol doesn't have to worry about the transport - Twisted supports SSL, TCP and unix domain sockets right now, without having to make any change to the protocols. 2) Twisted is designed to run multiple servers and protocols at the same time, and these can be changed at runtime. It already includes pure python support for HTTP, FTP, LDAP, SMTP, POP3, DNS, telnet, AIM TOC, and IRC, all integrated with the main event loop (all have server support except DNS and LDAP). Adding new protocols to Zope is not easy, at the moment. 3) Twisted is being actively developed and extended. medusa less so. 4) Good integration with threads - while event based, twisted has a very nice model for dealing with threaded apps. 5) Twisted has Perspective Broker, an async.ready remote-object protocol that supports caching, object migration, and remote messaging, with integrated authentication and authorization. And it ideologically meshes with the object publisher notion in Zope. No, really :) Twisted already includes a high-level web framework, but Zope probably would not use it, and instead build its own on top of twisted's low-level http support. ___ 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 ) ___ 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 )

oodb philosophics ;) was: Re: [Zope-dev] Experiments with ORMapping
Hi shane, I think the motivation people want an RDBMS storage beneth zodb is because they understand RDBMSes these days are performant, relieable and can quiete easy maintained. I've seen Java implementations using this approach to achive persistens using as example Powertier[tm] to explicit map oop data to an RDBMS. I didnt like it because you have to map your objects each time you create a class, keep in mind not to infere with others etc... Would it not be better to improve the abilities of the Filestorage to handle updates better? May be most of the storage system in C? With logfiles like modern RDBMSes use to incorporate fast changes? However, to avoid pickling/unpickling and may be to update on attribute-change, we need the approach you mentioned. What about using a real oodb for zope?

Re: [Zope-dev] another Zope hanging..
Hi, most problems with hanging zope come from external RDBMS-access. You wont see anything useful in the logs because there are some objects published before the *sql-method is hanging. If you have a monitor program for your database, you see many blocks on tables or rows during this times. I expect it with DB-adapters not fully thread aware and - with to high timeout. In fact it seems we need timeoutsockets and asynchronous rdb-access. If one thread is hanging, in the scope of 120 instructions, zope has to wait before the global interpreter lock frees. So if its stuck in the call of a C library (database adaptors are most in C) it cannot continue until the call returns. Regards Tino Wildenhain --On Donnerstag, 3.

Instead reference only an index of a list with the columns to sort. oder by dtml-sqlvar orderindex type=int is also a solution. The index ranges from 1 to number of returned values. Regards Tino You can change the properties of an object in DTML by callling its manage_changeProperties method, for example: dtml-call expr="foo.manage_changeProperties(bar='New Value')" will changes the value of foo's bar property to 'New Value'. There are several ways of getting the effect of assigning variables in DTML, but it really isn't meant to have a direct way of declaring and assigning variables. The way you're trying to use an object's properties will, I believe, cause problems in the case of simultaneous users, because it will act as a global variable.

My simple question is how do I assign a value to this variable inside of the dtml method!

It's cool. Your patches are big and therefore, naturally, are a bit worrisome to us in terms of checking them into the core. Do you have a set of test DTML scripts that verify your patch? Say, a set of scripts that verifies backwards compatibity, and a set of scripts that verifies the new functionality? I would suggest even investigating "ZUnit" and creating DTML unit tests. Then we would *really* love you. ;) Have to find this ZUnit... ;) Ok, I made some further tests and improvements. There was a mistake (ok, it comes from variables spilled randomly over DT_In.py and DT_InSV.py ;) with the prefix. In some cases it wasnt there as supposed. Now all the prefix-handling should be ok. I've made an yet simple test-suite, all available thru http://www.zope.org/Members/tino/ (See "Patch for dtml-in" there) Note: the prefix prepends only the in-tags own variables. Any attribute coming from the sequence is untouched. This is also true for statistic variables and the magic "mapping" symbol. While it could easy be implemented, I think prefixing all attributes is not such a good idea. If you are ilterating over database queries you can rename the attributes there.

[Zope] Patch to avoid hypenation variables and more
Hi there, finally I want to release my patch for the in-tag. I hope it finds its way into the source-tree. I was sick writing such ugly constructs as _[_['sequence-item']] and so on, so I patched DT_In.py and DT_InSV.py (in lib/python/DocumentTemplate) to use sequence_item as well. All hypenation variables have now a second representation with underscores instead of hypenation. I hope, some time we can drop these hypenation variables. The second problem is if you put one in-tag into another. You have to use dtml-let oder REQUEST.set() with variables of the outher in-tag to be able to reference them in the inner loop.

You get better performance and much cleaner solutions (better to maintain and more secure) then any of the mentioned solutions allow. Many things are better done completely different in zope. How does Zope deal with serving virtual domains off of a single NT box? What approach would that require? There are several options. One of it is site-access (product at zope.org) You can also server different instances of zope off the same server (using different ports and apache or squid in front as dispatcher) Zope looks like a really nice platform, any real-world evaluations would be most appreciated...

Re: [Zope] expr=id 'index_html issue
hi,
as usual, if such things happen, "id" is a method.
it gets called by zope if you just use dtml-var on it.
So either use id() or better, look for title and
if not set (dont set a title on html_index then)
dont display it.

dtml-in expr="objectValues('DTML Method')" sort="title"
dtml-if expr="id 'index_html'"

Does anyone know why?

Re: [Zope] Zope not starting after VaryTag install
Hi Didier,
so it looks like the vary Tag may be not compliant
to older ( 2.2.x) releases of Zope?
I have to check this. You should probably check if
you really need an ancient version of Zope ;-)
I'm really wondering how the tag can cause such a
behavior. Its almost an extract of the mime-tag
implementation which ships with zope.
Certanly you have a copy of your Data.fs before installation?
Good luck

I can open up a high port on your machine that'll let me connect to your Zope process in a python interpreter prompt. Then your server is my oister. Thats badly true, but importing of a whole bunch of objects is also often needed. IIRC does pickle only handle instance data but not class code. (although I see using of marshal in the import code which does in fact import code as oposite to pickle) Importing instance data schould not be a problem since it can only work if the user in question has access to the classes. This access is already handled by permissions. Moreover we could restrict importing via web to the superuser at all. Allowing imports from arbitrary paths will let me exploit security holes in other internet daemons on your machine to create a pickle file for import; preferably the /tmp directory as it is world writeable. Restricting imports to one directory allows you to be much more restrictive as to who can write there. You can set up restricted FTP access or even only allow scp (ssh encrypted file transfer) for trusted people to upload exports to the Zope import directory if you need to give others import rights. Uh, do you know any ssh-daemon for windows? ;-) Regards ;-) Tino ___ 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] Import from file via management-interface
Hi all,
I found it very disturbing having to get my .zexp exports
into the subdirectory 'import' of the server and then using
the management-interface to do the actual import.
So I patched ObjectManager and the compaining dtml-file.
Please check them out (included in the mail, sorry for the
traffic) if I should post them to the collector.
Regards
Tino

So it took me 3.5h to rewrite it from scratch. This time it works according to rfc2616 (HTTP/1.1). Its just one solution for serving multi language documents, but it works very well.

I would say string.replace() should be a bit faster.

Re: [Zope] SQL Methods

This worked fine in Zope 2.1.6 so I guess it has something to do with the new security model. I also have explicit ownership of all objects that I'm working with - still no luck. There was a bug in sql-methods returning subobjects without giving them the proper access rights. This was due to a change in the security mechanism on 2.2.x. The default policy is now: disallow everything as log as its not explicitely permittet. I would suggest to look for the patch on sql-methods or simply upgrade to the latest 2.2.1 where this (and much more) has already been fixed.

Re: [Zope] Changing a Z object's __class__ dynamically
hi ... I don't know what exactly is going on. My conjectures are: (1) Digicool people have re-written Python's system function setattr(), so that when it is an Z Object, the __class__ cannot be changed. (2) Caching: when I change the class of a Z Object, somehow it does not reflected in the Z Object's memory-cached version. When I remember correcly, DC's setattr does not change attributes with leading underscore in a persistence way. These attributes are considered to be local.

So you should set headers with RESPONSE.setHeader() hth Tino Wildenhain ___ 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 )
Re: [Zope] space in variable returned by queries

Hello,
I'm working with Zope and PostgreSQL
When i do a query, Zope returns me a variable with a space at the end
Do you know how i can do not to have this space at the end?
dtml-var "_.strip(var_with_space_at_the_end)" should do.
Or dtml-call
"REQUEST.set('var_without_space_at_the_end',_.strip(var_with_space))"

Re: [Zope] just html, help, help, help !!!
Hi,
Just some hints: think about it is really necesary to use JS here.
Often it does not add comfortableness for the user.
If it really brings gain in functionallyty, it schould work
both ways, with and without JS.
In the example below, a ular reform in the parent can be used.
In a Zopish way, you would take an extra submit button (or image)
to open a new part of the page to input the needed information.

Subject: [Zope] "just html", help, help, help !!!
Hello,
Can you help me ???
I have one page with a "form", in this page I have an "OnClick" who open a
new page who have some informations and when I "Submit" (I think that I must
use a form also in this page to send the informations to the first page), I
want to receive the informations on the first page, in a input or something
else ???
We are three people for find the answer but we don't find the way, this is
why I call you...
The key is `opener' propery of `window'object
(browser must be capable JavaScript 1.1)
I have tested it - just for you :) - with IE5 and NN4.61
Just a draft:
The parent HTML:
HTML
BODY
FORM NAME=aForm
INPUT TYPE=TEXT VALUE="DEFAULT"
/FORM
A HREF="anInvalidLink" OnClick="window.open('child','childWindow');return
false;"A link to a child/a
/BODY
/HTML
The child:
HTML
BODY
SCRIPT
function setInParent(aString)
{
window.opener.document.forms[0].elements[0].value=aString;
}
/SCRIPT
FORM NAME=childForm
OnSubmit="setInParent(document.childForm.elements[0].value)"
INPUT TYPE=TEXT VALUE="DEFAULT_CHILD"
INPUT TYPE=SUBMIT
/FORM
/BODY
/HTML

I know that it's going to be a good day.
