Re: [Zope-dev] Zope RPMs/debs and Linux FHS
This looks GREAT!!
A couple of points:
*) Python 2.2.x ?? This is scheduled for Zope 3 ?? Is there any way this
could find its way in to a 2.x release?
*) Byte compiling: Why not schedule an 'at' job to do the byte compile?
*) Ownership/perms on the 'var' dir, this will need to be the same as the
user Zope runs as, which I assume is not the same as ${zopeuser}
Minor personal request:
*) Is there any way to detect if apache is installed, and have zope run as
the apache user? This would be great for CGI support, etc.

Subject: [Zope-dev] Zope RPMs/debs and Linux FHS
Hi all,
I am working towards a unified Zope configuration and installation
system on a branch of Zope named the 'chrism-install-branch'.
I have given the buildout process on that branch the ability to create
an RPM distribution of Zope. I intend later to give the buildout
process the ability to create Debian .debs as well and maybe Solaris
packages... I am doing this with the expectation that we might be able
to provide RPM and .deb distros of Zope from zope.org instead of our
current generic Linux as tarball distro. I haven't looked yet at the
Debian packaging of Zope (by Gregor Hoffleit), but I intend to do that
next to get some more ideas.
I know there are already at least two flavors of Zope RPMs which Jeff
Rush helped to package. There are a number of differences between the
packaging of the RPMs generated by my branch and the packaging of Jeff's
RPMs:
- One of Jeff's distros breaks Zope up into many different packages,
while another installs it as one or two. Mine only has one
distribution flavor: a single package.
- Jeff's puts some stuff into the current prevailing python's
site-packages directory and some other stuff into /usr/share/zope.
Mine puts nothing into site-packages, and installs all Zope software
into /opt/zope.
- Jeff's creates an INSTANCE_HOME in /var/zope. Mine creates an
INSTANCE_HOME in /var/opt/zope. I don't know if this is the right
thing but in reading the Linux FHS, it advises to not create
subdirectories of var directly... so I don't.
- Jeff's puts pid files into /var/run, while mine creates pid files
directly in INSTANCE_HOME/var.
- Jeff's puts log files into /var/log while mine puts them into
INSTANCE_HOME/var.
I am wondering if:
- anybody has opinions on the packaging layout. Why is it advantageous
to have many packages rather than one?
- anybody has any opinions of where Zope files distributed via RPMs and
debs should really go, especially wrt to the Linux FHS. I'm not sure
there is a right answer, but I don't know beans about this, so I
figure I'll ask. A file named 'Zope.spec.in' is attached to this
email which is the input file to create a Zope RPM spec file during
the make process, to give a better idea of how this works.
Thanks!

Re: [Zope-dev] Slow zope on windows 2000?
From: [EMAIL PROTECTED] Hello, I have a question for you zope administrators out there : What are your experiences whith zope running on Windows NT/2K? No matter what I try , zope will run significant faster on a Unixlike system (with the same hardware), especially when working alot with the ZCatalog. Very much so! On a Win2k with Dual P3 1Ghz Zope runs slower than the same install on a Linux box with 1 P133 (I have tested this on multiple different configurations and every time it comes out the same) Do you guys have any proposals how to make zope run faster on windows? My own experience is also that zope runs faster with the start.bat way instead as a Windows NT Service. Strange, because I tried several numbers of threads with both ways with the same startup parameters. I have yet to find any platform independant product that runs faster on windows. The only things on windows that are faster are programs that use windows specific APIs (Mainly designed to _prevent_ platform independance). Best bet:- Go get a £300 ($450) pc and install Linux on it and use your Windows box for what windows is good at (Sugestions anyone???) - This is what I did, and the results were not at all disappointing.

Nope... we have been down this path before. Note this what I need (see below on why) requires modification, and not simple replacement, of whatever code is currently running. As far as I can see, Patchkit does nothing to make this possible. The problem is that A) monkey patches may or may not have been applied before a given product sees anything, and B) there is no reasonable way to discover what (or even if) patches have been applied by other products. If you are going to go down the monkeypatch path, then there needs to be some way for other monkeypatchers to discover what you have done, so that they can decide if they can 1) extend your code to be compatible with theirs, 2) refuse to install their code, or 3) blow your pre-existing code away. Current monkeypatch code always does 3. Patchkit has, as far as I can tell no way to make 1 or 2 easier. It just makes it easier to blow other people's work away! Background: I am debian maintainer for zope-zshell. The debian release is currently a version behind. I have been holding off updating it because I would like the ZMI box. I cannot modify manage_main.py directly, because it belongs to the zope package and the changes would be blown away on any upgrade of zope. I was starting to turn it into a python product, but zope-externaleditor has been packaged, and it monkeypatches manage_main. The naive thing to do would be to install it as a monkeypatch. But then, either I blow away externaleditor, or externaleditor blows away zshell, depending on the order in which zope installs products on startup. There are several other products that monkeypatch manage_main as well, building a nice mutual destruction club. Jim Penny PS: I would also like to hear general responses to Jerome's proposal. Clearly this was not an API, no arguments have been specified. But is there a general consensus that this is a reasonable thing to do? Please, if it isn't to late, could we make it a 2.6 thing?

It needs a place to type a command, that is, it is a free form text box. That is, zshell gives zope a CLI. Historically, you have had to click on something to get to the CLI. If it is made part of the ZMI, then the CLI is part of every management window, with no extra work needed to use it. What is needed is to insert a form with a single textbox as element. This seems to be a hard problem. Introducing monkeypatches, has, in my opinion made it harder, before people would have simply given up. Hmm, the more you describe this, the less the ObjectManager's contents view seems quite the right place for it. If the relationship to the current ObjectManager is required, then what is the problem with a ZMI tab (Titled zShell or Command Line or whatever). This could easily be implimented, would survive upgrades, and (To me at least) would be a more logical interface.

Re: [Zope-Coders] Re: [Zope-dev] DTML and REQUEST data changesabout to be checked in
I'd like to second this. It was one of the contibuting factors in the decision of my former employers to opt for spectra instead of a Zope solution (That already existed!!). I, in contrary, appreciate the openess and fast response with respect to security problems. I do not install most hotfixes because the vulnerabilities do not affect our sites but it is a good feeling that there are fast fixes when this would be once the case. In some way we need to make it clear that most hotfixes don't matter for most sites. A lot of hotfixes ensured that users who could write DTML couldn't get extra privileges. They really only mattered for sites like zope.org, where anyone with an email address is allowed to write code that will be executed directly on the server. But: You are exactly right... but... The problem is not one of clarity of labling, it's one of targetting: The people that actually make this level of decision (i.e. board level execs) are not techies, and are just not interested in _why_ the fix is needed, or in _what_ technical problem it fixes, but that ZC (visibly) releases 'n' fixes per month for Zope, while M$ (visibly) releases less than that number per year for IIS/ASP - Therefore, Zope must be the less stable/reliable product etc? The logic is flawed, we all know that, but who is volunteering to visit every companies senior execs worldwide and spend the time to make them care enough? The hotfixes, and new releases need to be marketted (I use that word loosely) quite differently, new releases are A Good Thing(tm), while the fixes need to be under the hood where the execs won't be bothered by them, but the techies can find them when they need them. I appologise, in advance, for the sweeping generalization that all execs are like Dilbert's pointy-haired boss, but some really are!

Subject: Re: [Zope-dev] Nesting Forms
Although I would probably avoid what you are trying to do, it doesn't seem
that hard. Here is how I would do it (Which I think is just an extension
of
the other sugestions here).
Have one base class which contains (For example class _base)
* a method to produce an empty, or almost empty, page - All classes will
override this.
* a DTML Method which contains header, form start, a call to the
method
above, form buttons, form end, footer. No classes will override
this.
Then each desendant class would work something like (e.g. class A(_base) )
* Override the method, get the HTML returned by _base.method() and add
your
new HTML to it.
* Do not override the DTML Method
All descendants of A could do the same by adding their own HTML onto the
end
of A.method() etc...
This should work (And could be repeated for as many screens as there are
in
the product), because the head/head, body/body and form/form
elements are NOT part of the HTML returned by the base class method, so
the
ordering should be correct.
Of course, you will need to do the same with the form handler functions,
but
that is basic python, and all products do that without thinking.
I hope this is clearer to you than it is to me now I am re-reading it. :)

I would prefer a more elegant approach. Perhaps I can define some
method in A that the dtml will reference, and then B can override

snippet).
That sounds good. It is how the ZMI works...
ZMI = Zope Management Interface (i.e., in the core app), or is this
something else? At any rate, I'm not sure what you're referring to,
or where to look.
First, I'm not exactly sure how to pick up the method from the
DTML.
There are two cases:
* view of an existing object
then the object is the client of the primary view.
Make all you snippets attributes of the object
and you can simply access them by name.
The ZMI does this. If necessary, look how it does.
The problem isn't just accessing them, but combining them. Say C is a
subclass of B is a subclass of A. Each subclass has the entire user
interface of its base class (aka superclass) and some extra stuff.
Either each class implements its novel stuff with a unique name. In
that case, I still have to make a separate dtml file for each,
referencing the appropriate names (though your suggestion below helps
on that).
Or each has the same name. Then the problem is how to get the
subclasses method to return its unique stuff plus everything in its
base class. For vanilla methods that's not a big deal, but if each is
a DTMLFile, I don't think it will work. More about that at the very
bottom.
* object creation form
That's much more difficult. ZMI does not reuse fragments for
this case.
There is a partial solution for DTMLFiles, but it is not nice
and restricted to DTML.
DTMLFile constructors accept a dictionary with default
name bindings. This way, you can customize your
DTMLFile with different bindings according to context,
e.g.
addAForm= DTMLFile('dtml/addForm', globals(),
comp1= AComp1
comp2= AComp2
...)
addBForm= DTMLFile('dtml/addForm', globals(),
comp1= BComp1
comp2= BComp2
...)
This suggests one semi-refined strategy: the file defines the maximal
interface, and then parts of it are guarded by dtml-if ... tests on
these
extra variables I pass in. I could even pass the class in, but I
suppose if I try to do issubclass(PassedInClass, MyApplicationClass)
in the dtml-if I will find that I lack security to access
PassedInClass, issubclass, or MyApplicationClass.
Second, I'm not sure if this is the best solution. For one thing,
I
would prefer to keep all my dtml in separate files, rather than
defining it into my methods.
You can have separate files and do something like:
class YourProduct:
mySnippet= DTMLFile('dtml/mySnippetFile',globals())
The problem comes if I stick the different interface segments in
different files, so A.dtml has the user interface for A and B.dtml has

Re: [Zope-dev] Last-modified and bobobase_modification_time
Ah, well, that is not quite true.

Bottom line, internal bugs to one side, Z2.x works a particular way, and is documented as doing so. This is a powerful and useful feature, and we are likely to severly impact the power and process of Zopeing by removing it.

Although you can use this to clever ends, it opens up many doors to misuse of a site or even significant security holes. For instance, it used to be possible to access the Control Panel (and shutdown Zope) as a user defined in a subfolder of the root who had the local Manager role, just by forming a URL like: http://somezope/myfolder/Control_Panel/manage_main The point is that this grants way too much power to the end user to muck up the namespaces. It is difficult, if not impossible to design an app in Zope today that accounts for all possible namespace variations gracefully, since there are effectively an infinite number of them for every given object in Zope based on different URLs. Now I won't argue that implicit acquisition isn't useful. It rules in solving (and simplifying) problems in creating highly coordinated objects. But, being an implicit and magical thing, it is better if it is invoked through an explicit gesture rather than simply being there all the time. Having it around all the time also makes it easy to use it when its not the best (or most robust) solution because it also excels in creating namespace chaos that is difficult to predict and account for.

Re: [Zope-dev] Re: stacks != easy to explain
Don't even get me started on that one! I don't think this is neccessarily a criticism of Zope though, or ZPT. We are all human, and apt to err. ZPT is imperfect, but the balance of opinion would appear to be that it is better than what has gone before. It is irritating to learn a new syntax, it is hard to read (Some of us design Zope sites TTW...) the flow of logic is obscure and sometimes downright impossible to follow, but people seem to work around it anyway. Much the same is true of the failure of Netscape, Microsoft, and all the others to even read, let alone follow, the defined standards on, well, just about anything. There is one important point being missed here though - Why should the non-programmers be interested in the coding? If the concept of a stack is to hard for them to understand, so what? Shouldn't they be designing plain pages, which the coded templates simply render? Or are we now passing off the task of designing look and feel to non-experts? Anyone want to find another area of the industry to dilute? Now, return to the Marc and Chris' last comments, why exactly can't leading browsers follow standards, because they are written by people that can't program, in languages that were made simple for the sake of non-experts.

Re: [Zope-dev] Re: ZClasses useful! [Was: ZMI / JavaScript brainstorm]
Maybe a little Perl psychology might help us here, i.e. There is more than one way to do it - Some are faster, some more feature rich, and (in this case) some are TTW codeable. The only ones that are actually _wrong_ are the ones that don't work at all. ZClasses are one of the two things that bring Zope up to and above the level of the competition (In this case Coldfusion) IMHO - TTW coding, including writing products TTW, and DTML which is far more powerful and focused than the competitions offering. I think that blindly disposing of both, just because a newer idea has come along is just that - blind. So what if ZPT is more (choose your comparison here) than DTML? DTML is far easier to learn, far easier to read, far easier to write, and much much easier to explain to newbies. It has always been clear that ZClasses are the poor relation of Python products, but even that does not earn ZClasses a death warant (IMHO) - Have you never needed a quick fix product that needs writing in a few minutes and in a week will no longer be needed?

For people who dont know coding or want to do quick prototyping they have a place. However if someone asks me how to do a product, I normally give them the choice: use ZClasses but I would strongly recommend using a Product etc (and then be ready with the reasons why which is the next question). Unfortunately people deciding the right and wrong ways for other people to code is a trait sometimes found in Python / Zope world.

I just don't see the need to throw out the ZMI - Are we in a baby/bathwater situation here? address. While CSS support varies widely in all the various browsers, and I think we should *ship* with a CSS file that requires a standards-compliant browser such as those that Toby lists, I see *no reason* why we should design the html itself so that a NS4 user could not use the default skin simply by building him or her a new CSS file.

Re: [Zope-dev] OpenSSH configuration between ZEO clients storage server
Yes. The best solution would be for the ZEO protocol to support auth and crypto natively... +10 (At least) The next best solution (while you wait) is to use CIPE ;-) Could be, if you can: a) Get your customers to run a platform it's been ported to b) Run something so low level that is esentially replacing functionality that is already in their kernels. Anyone here want to try to explain to *ahem* technically non-expert *ahem* clients why PPTP is bad (Inspite of _all_ major and minor OS's now bundling support for it). As far as I understand it, even regular TCP port forwarding is TCP over TCP and suffers from the unreliable carrier assumption causing excess (eg retransmit) traffic over a reliable channel. By port-forwarding you mean... ? a) A firewall PC that receives an external connection and reroutes it to a machine on the inside? No, this is not TCP/TCP. b) An apache that takes a connection and forwards it to Zope? No, this is not TCP/TCP. What port forwarding are we talking about here? Consider: host --TCP-- local interface --TCP tunnel-- local interface --TCP-- host host --TCP-- virtual loopback interface --TCP-- host In this common port forwarding scenario, the SSH or SSL tunnel creates a virtual single loopback interface that the two hosts use to talk to each other, using TCP. The transport that joins these two physical interfaces to create one virtual loopback interface is also TCP. Therefore it's TCP over TCP If you insist on using User Land utils for Kernel Land functions, this will be the result IMHO.

I was wondering if there was any consensus on how best to fix or compensate for the unfortunate behaviour of IE6 with regards to the width calculation of textarea boxes. For anyone who hasn't seen it, the full-width texareas that are everywhere in the ZMI suddenly started pushing the width out in IE6, causing the horizontal scrollbar to become active, and generally making ZMI editing life miserable. Would it be possible to include in 2.6 (or 2.5.1, even better) a user preference, sitewide configuration setting, or other means of suppressing a few pixels/percent of that default width? I'm loathe to apply a massive search-replace to put 95% in my local ZMI source, and IE6 must be a common enough platform for Zope users to warrant a workaround. I wouldn't hold my breath that MS would fix IE or anything sensible like that.

Re: [Zope-dev] Error removing NT Service
Two points about deleting services (Well one really, just looked at from two angles): 1) Services must have fully stopped before you delete them, or they get marked for deletion on the next reboot (Good, solid server software: expecting frequent reboots!) 2) The service must have had all the SCM handles closed otherwise the same happens What is probably happening is that the SCM handle from the service shutdown has been deleted, but python or something still has a reference to it that has not been garbage collected yet.

The current, not yet available, incarnation is very highly based on PythonScripts, however I wondered if something better couldn't be done, because it seems to me to be an unneeded repetition of most of the PythonScripts' code : AnyScripts AnyScripts would have a mandatory first line similar to the one of any Unix shell script. By unix shell script I mean any script which can be launched directly under Unix, not only bash or csh scripts, but also perl, tcl, etc... So an AnyScript would contain a first line like : #! /scripts/interpreter And the execution of this script in the context on which it is applied would be delegated to another object present in the path which was set on this very first line, i.e. /scripts/interpreter So you could put any interpreter object of your choice in for example the /scripts folder (no path would mean search the interpreter object within the acquisition path) For example PythonScripts would contain something like : #! /builtins/python or something like that. Out of my mind I can already think of a ZShell interpreter object, but why not other types of interpreter objects : perl tcl C (the language ! Why not after all) etc... Each interpreter object would have at least two methods : compile() = returns a code object from source code, if meaningful (otherwise returns the source unchanged), to be stored in the AnyScript object which calls the compile() method. execute() = executes the above code object. This method of the Interpreter object would be called by the AnyScript object at run time, passing it the code object obtained with compile() Of course all of this come straight out of my mind, and there would probably be some problems I'm not able to understand yet... Bound variables would be like for PythonScripts, with the exception of their content would be the best format for the Interpreter in question, so each Interpreter object would probably also have a bind() method which would bind vars in the preferred format for the AnyScript object which calls this method, and would be accessible using the preferred syntax of the langage in question, e.g. : for PythonScripts, vars like context would be Zope Objects, like they currently are. for ZShell AnyScripts, vars like context, would be paths to Zope Objects, and accessible with names like $context for example. for C AnyScripts, vars would probably be something like PyObjects pointers. etc... So AnyScripts objects would interact with their interpreter object of choice to compile their source code, bind their vars, then finally execute the code and get the result back. What do you all think about this idea ? Are any of you interested ? I admit I don't know anything about the feasability of such a project with other languages than ZShell, however if a single implementation could be done, then anyone could add his own interpreter later...

The aim in my sugestion is to allow ideas such as Marc's here to be applied to patches as well has fully formed products. If all patches were loaded into a PatchManager, there could be a global off switch, and an individual off switch for each patch. This would also encorage patch writers to make their patches in a common style, that could be easily queried (On the Control_Panel or a sub page) to report on patches and their basic actions.

Subject: [Zope-dev] Adding gzip compression to HTTPResponse.py
I'm looking for architectural suggestions for adding gzip compression to
HTTPResponse for text types.
First, I just wanted to compress xml-rpc output, since I'm returing lots
of table data as
XML text (not objects), then loading that text/xml into a DOM for XSLT
processing.
I hacked the attached code into HTTPResponse, at the end of setBody. It
works for
xml-rpc responses and I suppose any text output, so long as the response
object has a
header named dogzip set.
I know dogzip is a stupid name, but this is just a testing thing.
Representative compressions:
compress oldlen 150366 new len 11926
compress oldlen 204382 new len 14170
compress oldlen 12746 new len 1364
As you can see, very useful compressions for xml-rpc output.
But for HTML output, what's really needed is I think a special kind of
Cache Object.
One that combines HTTP Caching with Ram caching to keep gzip compressed
objects
in memory.
Some HTML pages are really quite large, and gzip compression can make a
noticable
difference. Just the javascript code sizes themselves are .. really big.
For xml-rpc, obviously every response must be compressed if it's worth
it, and I can
see that having to set a response property on a per request basis is
appropriate for
xml-rpc.
But for text file objects, Page Templates and stuff.. How does setBody
work with Ram
Cache objects? I have some ideas...
Anyone think this is worthwhile?
Also, RESPONSE.setBody really should have access to REQUEST.headers.
What's
the clean way to do that? Just pass the request object to response
object's init
method?
Here's quick gzip compression hack-in, based on code posted by Neil
Schemenauer
Thanks Neil.

Re: [Zope-dev] Zope on Linux and Database as MS-SQL Server on WinNT
Just to paint the complete picture (As I think the readme/news article does not at the moment). 1) The ODBC Socket Server software for the Windows database server can be downloaded from http://odbc.sourceforge.net/ which is the primary source for Team FXML's excellant product. 2) The next releases of XMLKit and ZDataQueryKit will see the ODBC Socket Server Client move from XMLKit to ZDataQueryKit (Sorry about this) so that they can all use the new relational logic and visual design tools. XMLKit will continue to support the product (Erm somehow), but you will not be able to add the XMLKit version.

Re: [Zope-dev] How to automatically redirect publishing request to another folder?
Try using a site access rule, it's almost as powerfull as the traversal
roulette, but it happens after zope has finished traversing. You could write
a Python Script, something like:
=
import string
if string.split(context.REQUEST['PATH_INFO'], '/')[-1] ==
'my_parent_folder':
context.REQUEST.RESPONSE.redirect('my_first_slide')
=
CAUTION: Remember how to turn off site access rules (Adding
_SUPPRESS_ACCESSRULE to the begining of the path) incase it all goes wrong

Subject: [Zope-dev] How to automatically redirect publishing request to
another folder?
Hello:
We have a Slideshow product that is similar to OrderedFolder in that it
maintains an ordered
list of contents. Each subfolder represents a slide. To view a
particular slide, you navigate to the
subfolder, it automatically calls index_html, and there's your slide.
All of the slides actually acquire their index_html DTMLDocument from
high up on the food chain. The index_html in turn calls dtml-var
body and the body is, of
course, different for each slide. This is convenient, b/c each slide
shares header/footer/etc.
My problem is this. When you type in the URL of the top level folder
(that is, the slideshow folder itself)
I want Zope to behave as if you typed in the URL of the first slide
automagically. The Slideshow product
has an easy way to get our mitts on the firstSlide object, so that part
is not a problem, but I cannot get it to work.
Of course, if I create an index_html() method directly in my
Slideshow.py, that screws up my acquisition.
Zope dies with an infinite recursion.
Next try: using __bobo_traverse__() That is a little bit nasty, b/c
you have to figure out whether you are
the end destination or if Zope is just passin' thru.
[ See http://www.zope.org//Members/andym/wiki/MessingWithTraversal ]
Nothing works quite right. Conceptually I know what I want to do:
call index_html on firstSlide()
in the _context_ of firstSlide(). However, my Zope Zen is failing me.
Has anyone done something like this?
Thanks in advance!

Re: [Zope-dev] Re: [Zope] Security Assertions
Just a quick note on this point, there are two points during startup when a product can get control: 1) When the __init__.py is imported 2) When the initialize function within that __init__.py is called. These seem to occur quite far apart in terms of loaded modules so to get something done early, do it at import time.

Thanks very much for the patch! We don't maintain 2.3.X anymore (at least not that I know of, although somebody probably should). And the 2.4 branch is a little up in the air at the moment. There will be a 2.4.4 to fix crashing issues but I don't know what the policy will be for introducing noncrash bugfixes. 2.5 already has the fix. So... this is why I suggested a monkeypatch. What I meant by monkeypatch is ... well, now you made me say it... hotfix. There, I said it. In other words, a Product that you can download and install that dynamically changes the running code without actually requiring that folks running 2.3.X/2.4.X patch their source code. Note that this is *not* a vulnerability in case anybody gets nervous. It is a bug that has to do with Zope security, but it is not a vulnerability. (That's why I didn't want to use the term hotfix) You can make a monkey patch by creating code modeled after ZC hotfixes that does some specific set of steps. In this case, you'd probably want to replace the ModuleSecurityInfo class/function with your fixed function dynamically. Of course, in this case you'd need a way to arrange that it was among the first Products registered (in order for the other Products to make use of the patched function).

[Zope-dev] One object where there should be two
I am having a problem with XMLKit. I have the following code in which should
use one disk based DTML Method and produce two slightly different creation
forms, one for XML and one for RSS (a specialization of the XML form):-
manage_addRSSDocumentForm = Globals.DTMLFile('www/addXMLDocument',
globals(), kind='RSS')
manage_addXMLDocumentForm = Globals.DTMLFile('www/addXMLDocument',
globals(), kind='XML')
The problem is that both of my constructors run the RSS form, the XML
version never gets displayed. I have checked the code in __init__ and it
appears fine:-
context.registerClass(
XMLDocument.XMLDocument,
meta_type='XML Document',
permission='Add XML Documents',
icon='www/XMLDocument.gif',
constructors=(
XMLDocument.manage_addXMLDocumentForm,
XMLDocument.manage_addXMLDocument,
),
)

meta_type='RSS Document',
permission='Add RSS Documents',
icon='www/RSSDocument.gif',
constructors=(
XMLDocument.manage_addRSSDocumentForm,
XMLDocument.manage_addRSSDocument,
),
)
I've tried just about everything I can think of, can anyone shed any light?
Is this a special rule I have broken?
Thanks.

Subject: [Zope-dev] RAMCacheManager and gzip
Hi,
Is it possible to marry the RAMCacheManager and gzip?
I'm just working on a little shop and - for speed's sake - do 'ram-cache'
the article-listings and push all the Zope-Content through mod_gzip. With
this combination, I'm getting it 3x faster in Zope and 5x faster over the
wire (normally 64k). That's great so far. But I don't see any sense in
zipping cached content over and over, so I tried to zip the cached data in
RAMCacheManager. In my first attempt, i replaced:
ZCache_get (RAMCacheManager.py):
entry.access_count = entry.access_count + 1
return entry.data
with:
entry.access_count = entry.access_count + 1
ob.REQUEST.RESPONSE.setHeader('Content-Encoding','compress')
return zlib.compress(entry.data)
The results:
1.
This works with Mozilla 0.96 only for very small entry.data. When I set
entry.data to 'XX', it works, but any real page gets
'htmlbody/html/body' as the result.

I'm willing to spend some days of work for this feature, but although I
have
2 years experience in Python I'm quite new to Zope and Internet-RFC's
and this is definitely a point, where I would appreciate some hints from
more experienced Zope-programmers (or a product, of course -- or the

All permissions would have another setting to specify it group. That way the Zope base permissions could be grouped together into a Zope Base persmission group. We could group our in an Torped Easy Publisher permission group, and so on. Good idea or stupid? Well, for your use you could just hardcode some permission groups and include them in the dtml-file which resembles zopes security screen. A little bit javascript and selecting one of your groups would automagically be checked when you check one of your groups. What I'm missig more is flexibility for the Add object mechanism. The possibility to install products not globally, but locally for a folder and it's subfolders and some hierachical sorting of add type selectbox.

Re: [Zope-dev] Any interest in a set of Zope products to support CVS-versioned, XML/XSLT-based Zope development?
I'll leave the CVS to others, XML stuff is right where I am looking at the moment. My XML kit is not standards based (And anyone who has spoken to me about XMLKit will know that I don't like the current SAX/DOM implementations in python as they try to make Python think like Java...). I have been looking to greatly improve the proccessing in my XMLDocument because it is currently both counter-intuitive and clumsy to use. I may have misunderstood, but my XMLFile and XMLProxy objects my provide some of what you were taking about with the Zope access to XML both inside and outside of your Zope. Maybe we can move XMLKit in the directions you are talking of aswell? The two criteria that I have are: 1) The code needs to be Python, not C (For now at least) for the platform independance. (A number of Zope products I would love to use will only run on one platform and I need complete platform independance for most of my installations). 2) The product needs to be easy enough to use that a someone who is not an XML-guru can use it to good effect.

Greetings! We at Ariel have recently started using Zope and, needless to say, we are enjoying a large increase in productivity compared to our previous Apache-Cocoon2-Tomcat-Servlet-dbXML-Java environment. In our opinion, Zope is about a year or two ahead of where these guys are in many respects. Kudos! The main problems we faced while moving to Zope were these: - how to support version control, branching, merging, tagging, etc. etc. (we use CVS) - how to support our XML/XSLT-pipeline based document publishing paradigm (cf Cocoon2) We have seen several efforts underway to address these issues within the Zope community. We have gone a slightly different direction, but hope to contribute to these efforts in some way. In our environment: - multiple author/developers work on the same documents at the same time - we work on content for several clients at the same time - web pages are cobbled together from content pulled from several XML documents, according to a PagePolicy (similar to the way articles are collected and pasted into a newspaper page). - the PagePolicies can be changed independent of the underlying content (header-body-leftmargin-footer, header-body, etc) - all content is in XML, transformed into HTML/DTML by XSLT. - we use lots of tools other than Zope, so we want to keep our content in XML, not pickled Zope objects. (hold the pickles ;-) In order to make all this work, we created three Zope Products: ExternalFile: Points to a file in the filesystem. Unlike ExtFile, it is not copied into a repository directory, but remains in situ Behaves similarly to a symbolic link in UNIX or windows shortcut. Metadata stays in Zope, but content stays in the file. index_html and __call__ return the content as if it were a real Zope object, so Zope doesn't know the difference. :-) Due to permissioning and other possible problems, this is probably only appropriate for development, not production. In future, we hope to add an option to copy in the content to ZODB, essentially converting it to a DTMLDocument. At that point we will probably rename the class ExternalizableFile more on this later. CVSFile: inherits from ExternalFile.Same thing, but the file is assumed to be inside of a CVS sandbox. Includes buttons for doing normal cvs commands. Sandboxdir is stored in a cookie, so each developer can access his own sandbox via THE SAME ZOPE OBJECT. That is, all developers can share a single Zope server but each see content from his own sandbox. (play in your own sandbox :-) This avoids the locking issues and other problems inherent in things like CVSwebClient. It also enables the content to stay native rather than becoming a Zope extract like in ZCVSMixin/ZCVSFolder. XMLDocument: (Sorry for the name clash). Inherits from CVSFile.Has a notion of a transformer property that points to an XSLT transformer. This enables it to be rendered automatically into HTML when __call__ or index_html is called.The underlying XML file can either be external or not. The XMLDocument object represents the entire file, as opposed to the parsedXML stuff that explodes a single document into multiple Zope objects for each XML node (correct me if I am wrong...) There is lots more to do, but we do have initial development versions of all three working in the lab. Is there interest in this kind of Product? Would it be considered heretical? ;-) Are others working

Users could have full write permissions to one branch only. * Backups or exporting from development to production servers. With the code all in one place, it would be possible to export the entire project from a development server and import it to the production server in one action (Ok, one action each end) eliminating the possibility of getting code and ZClasses out of sync. * Reducing the size of the Add List - This has to be a pain for everyone! However I also understand the appeal of having a central, restricted, ZClass repository as well, it just serves a different (Not incompatible) purpose.

I just don't see what I could really do with a ZClass in the instance space (reading this twice, see below for some possible examples). A totally different aspect is whether Zope should have something like an in-built support for virtual instances, i.e. sub-folders could be like full Zope instances, providing a local Products directory etc. To clarify, you use instance here in the spirit of Zope instance a-la INSTANCE_HOME and not in the sense of instance of a class... That would probably be a good thing. I am more in favor of getting things OUT of the instance folders than getting more stuff in. That is completely different from what I would like to do. It makes absolutely no sense to me why the Zope management interface displays database adaptors, user folders, and actual content objects all in the same folder. It makes lots of sense for me! Consider a large site hosting many applications, partly developed and maintained by different people/departments. It is very nice to be able to structure the site hierarchy into folders corresponding to appliciations and allow each team responsible for an application to put in everything they need for the implementation: database adapters, additional user definitions, special roles, ZClasses, Zope already allows this partially. Unfortunately, the product registry is global and not managed similar to user folders. Your proposed virtual instances would be an alternative solution. I could live with it, though I would not think it is better. To come back to the ZClass question: I see and use them mainly as templates. That's what they are good for. So they should reside in a template folder. Right now, this folder is the Products folder. Maybe we need local Products/Templates folders, so that it is possible to have ZClasses that just work locally or that overload a base ZClass defined up in the tree. But what we definitely don't need is freely floating ZClasses. I am much in favor to structure objects *NOT* according to type (e.g. all images in a folder, all SQL methods in a folder, all Scripts in a folder, ...) but according to applications/services: One folder for each service which contains everything needed only for this service: images, scripts, SQL methods, content, ZClasses, There are things that are used more globally.

Could this be an Internet Explorer failing to pass the AUTH info problem?
It sounds as though you are getting access to the edit tab via Anonymous permissions (Have you restricted access to the manage_main method using the __permissions__ settings)? In that case, Zope will not show you the other tabs because the Anonymous User is not allow to see them.
(Does it show that this one got me too???)

Subject: [Zope-dev] manage_tabs
Hi.
In my Zope product, I've got this;
manage_options = SimpleItem.manage_options+(
{'label':'Edit', 'action':'manage_main'},
)
If I view the management sceen of this product, I get four tabs (Undo,
Ownership, Security and Edit).
But If I click on Edit, all tabs but the edit tab is removed. Why?
My Edit dtml looks like this;
dtml-var manage_page_header
dtml-var manage_tabs
p class=form-help
This is the edit form.
/p
dtml-var manage_page_footer
Thanks,

RE: [Zope-dev] ZSQL and Normalized databases (or why ZSQL sucks)
Title: RE: [Zope-dev] ZSQL and Normalized databases (or why ZSQL sucks)
May be I am misunderstanding your problem here, but are you suggesting that
SELECT tab1.col1 col1, tab2.col1 col2
FROM ... etc ...
Does not expose 'col1' and 'col2' in the namespace for you? This is not my experience. Ok, I only have about 50 ZSQL methods on my intranet but they are all complex queries with column naming clashes. If it failed to work as you are suggesting, I would not have continued using Zope - Database connectivity was one of my criteria.
The normality (or abnormality) of your databases should make no difference, (Except to how complex your individual SQL statements become). What database are you running against? Maybe you have hit a database connector bug?
I have the following query that our sales-reps use to check how much product we sold in the last 'n' days/weeks/months etc...
-
PARAMS: dDate, sOffsetSize, nOffset
SELECT DISTINCT
Order_.Shipped_Date Date,
Region.Region_Name Region,
Employee.Number_ ID,
Territory.Territory_Name Territory,
Currency_Exchange_Rate.From_Currency_Code Currency,
SUM(Order_.Sub_Total - Order_.Order_Discount_Amount) Local,
Currency_Exchange_Rate.Current_Exchange_Rate * SUM(Order_.Sub_Total - Order_.Order_Discount_Amount) Dollar
FROM Region
INNER JOIN Territory ON Region.Region_Id = Territory.Region_Id
INNER JOIN Company ON Territory.Territory_ID = Company.Territory_ID
INNER JOIN Order_ ON Company.Company_ID = Order_.Bill_To_Company_ID
INNER JOIN Currency_Exchange_Rate ON Order_.Currency_ID = Currency_Exchange_Rate.From_Currency_ID
INNER JOIN Employee ON Order_.Account_Manager = Employee.Employee_Id
dtml-sqlgroup where
(Currency_Exchange_Rate.To_Currency_Code = 'USD')
dtml-and
(Order_.Status IN ('Invoiced', 'Billed', 'Shipped'))
dtml-and
(Order_.Shipped_Date IS NOT NULL)
dtml-and
(Order_.Sub_Total 0)
dtml-and
(datediff(day, Order_.Shipped_Date, 'dtml-var dDate') = 0)
dtml-and
(datediff(dtml-var sOffsetSize, Order_.Shipped_Date, 'dtml-var dDate') dtml-var nOffset)
/dtml-sqlgroup
GROUP BY Order_.Shipped_Date, Region.Region_Name, Employee.Number_, Territory.Territory_Name, Currency_Exchange_Rate.From_Currency_Code, Currency_Exchange_Rate.Current_Exchange_Rate
ORDER BY Region.Region_Name, Employee.Number_, Territory.Territory_Name, Currency_Exchange_Rate.From_Currency_Code
-
This exposes 'Date', 'Region', 'ID', 'Territory', 'Currency', 'Local' and 'Dollar' to the calling script. I use this from a Python product, python scripts and from DTML all the time (10's or 100's of times per day at least).
As far as the 'foo=0' example, if you set foo to 0, and do nothing in between to change it, of course a test for not equal to 0 will fail, what would you expect?

* Loosing the variable between the form and dtml-if
I don't understand this. I'm assuming that you are losing values that
are not in your argument list. All you have to do is add the arguments.
That isn't what I mean. Try this (typed in, so it may need to be
adjusted):
paramfoo=0/param
dtml-if expr=foo != 0Life is good/dtml-if
You'll NEVER get Life is good to print out. EVER. This is because
ZSQL is setting foo to 0. But dtml-var and dtml-sqlvar both work.
* Inability to handle table.field names for variables
* And enough flexibility to work around the above problems
This makes ZSQL extreamely nasty, and impossible to use with a
normalized database.
Database normalization isn't really an issue. It sounds like you're
really just having problems with the syntax of joins.
Nope, can do joins. Been doing joins (mainly inner). Not the
problem. The problem is that if I have tables like:
Table1
--
id
name
desc
Table2
--
id
Table1ID -- Foreign Key thrown in for fun.
name
desc
And I join them, then I MUST rename all the selects using AS:
select
Table1.id as id1
Table1.name as name1
...etc
Because I can't have zsql put the variables in the caller's
namespace as Table1.id. It puts them in as id (without the AS).
Fortunately, I found the column for sqltest (which is the other end
of ZSQL):
dtml-sqltest id1 column=Table1.id
What's the point? ZSQL sucks, how do I talk to the DB directly?
Grab the Python database adapter and write some python classes or
external methods to do what you need.
Can I use them from a python script? If not, what's the point? I
mean: External methods are nice to have when you have *no other
choice*, but they aren't something I'd want to debug and deal with
for object.
This makes things work MUCH better. So there are work arounds.
This isn't a work-around, it is the way that it is intended to be used.
RE: [Zope-dev] ZSQL and Normalized databases (or why ZSQL sucks)
Title: RE: [Zope-dev] ZSQL and Normalized databases (or why ZSQL sucks) I am using ZODBC talking to an MS-SQL7 database (Yack spit), so the syntax is a little different. As for the unchangeable defaults, I use defaults a lot, and I don't think I've ever seen your problem. What you appear to be trying to do with the ZSQL Method in your example strikes me as 'A Bad Idea'(tm). Having the schema of the returned data change depending on the value of a parameter seems to be asking for problems (IMHO). If you look back at the my last example, and replace the PARAMS with: dDate=2001/03/31 sOffsetSize=month nOffset=1 This certainly does work, I just tested it. Interestingly, so does: PARAMS: testval:int=0 dtml-if testval select count(shipped_date) cnt dtml-else select count(shipped_date)/2 halfcnt /dtml-if from order_ If you call it with testval=1, you get a column called cnt, with testval=0 you get a column called halfcnt.
