Re: [Zope-dev] Session Objects?

Basically we would like to use something similar to the session objects in ASP (yuck), or Java JSP/servlet model. I've seen several Zope session products although they all seem to hook directly to a DB and don't seem to provide memory persistence which is what we would like to use. Is there any existing products which do this? Boring old ZSQL Methods actually do exactly what you want - check out the caching options under the advanced tab (or the ZSQL docs on zope.org). The database will only be hit the first time you call the method with a given set of parameters, or when maximum time to cache expires. If your GUF hooks make use of ZSQL methods, you should have a look at tuning these too as it can be a big performance improvement. Actually - I tell a slight lie. The DB might be hit once for each thread, as the ZSQL cache is not shared between Zope threads. You need to be aware of this as a cached result may be refreshed in one thread but not yet expired in another and can give ambiguous results and unreproducable bugs if you are not aware of it when you are developing. -- ___ // Zen (alias Stuart Bishop) Work: [EMAIL PROTECTED] // E N Senior Systems Alchemist Play: [EMAIL PROTECTED] //__ Computer Science, RMIT WWW: http://www.cs.rmit.edu.au/~zen ___ 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 )

Re: [Zope-dev] ZCVS Mixin class... feedback sought.
Hi Chris, The basic idea is that you can export individual zope objects in a container to the filesystem, not to the 'var' directory, but to a directory under CVS control. Then you can commit, update, add, remove etc files (each of which is the xml representation of a zope object) and keep track of what's what. The only commands available zope right now are 'add' 'commit' and 'update'. You can of course use CVS in the normal way. -steve "Chris" == Chris Withers [EMAIL PROTECTED] writes: Chris Steve Spicklemire wrote: http://www.zope.org/Members/sspickle/ZCVSMixin Chris Sounds like a cool idea, but I don't really understand what Chris it does and how you use it.

Could you give use some enlightenment? JS ZCVSMixin is a sort of replacement for a standard Zope Folder JS Object. If you want to be able to maintain an entire Zope JS Folder (and everything in it) in CVS, use a ZCVSMixin Object JS instead. Then, from the Manage view, you get a new tab showing JS up that provides the interaction with CVS. That's basically right. Technically there are two parts. ZCVSMixin is a python "Product" that handles talking to CVS and importing and exporting objects. There is also a ZClass that inherits from both Folder, and ZCVSMixin to provide Folder behavior and methods while adding CVS support, hence the name Mixin. I believe you could really use the 'Mixin' to add CVS support to any subclass of ObjectManager, in a similar way. JS What it actually does is an Export as XML on the whole JS "folder", which then can be stored, view, checked out, checked JS back in, and otherwise thoroughly managed and maintained JS within CVS. For developers that are deep into Zope, and JS familiar with CVS, this represents some potent possibilites. Well.. close! It exports and imports all the objects in the folder individually. This way I can edit one method, then 'checkin' that change with CVS. Anyone else with access to my repository can do a 'checkout' from their Zope and get all the latest versions of my objects in their zope. Think of it as the public CVS that CD uses now to publish Zope itself, but taken to the level of tracking individual zope objects contained in Zope folders. I've just been playing with it.. and you can sorta get the idea looking at: http://cvs.spvi.com/cgi-bin/viewcvs.cgi/zopeObjs/testCVS/ With CVS you can tag revisions etc and take a snapshot in time of your zope objects, just like we do now with source code. JS Think about checking out a Zope Widget from a CVS on the other JS side of the planet, importing as XML into your local Zope, JS where it is marshalled back from its CVSish XML form into the JS original native Zope self. Now you can tweek it to your hearts JS content, export as XML, then check the updated version back JS in, where it becomes part of the trackable, archived, JS searchable CVS system.

Re: [Zope-dev] ZCVS Mixin class... feedback sought.
Good questions! You can just go to the 'admin' tab and type 'diff'. The admin tab lets you execute just about any cvs command with arguments stat, rtag etc etc. Doing a diff on a zexp file isn't going to be very helpful, though. Any thoughts on integrating some sort of xml diff tool? Conflicts.. uh... bad news. ;-) I think it's essentially impossible to 'merge' two different versions of a zope object... so my plan would be to pick one version, or the other. Login and logout are handled when you set up the directory on the filesystem. Basically you need to 'checkout' a module (maybe an empty module) into a directory on the filesystem before you can use it to keep the xml representations of your Zope objects. That checkout, might, or might not, require a login, depending on your CVSROOT. You must 'be' the zope user (the same user that the zope process runs as) when you checkout the module, so that zope can manage the contents. So essentially all checkins are by the same cvs user, so you lose the ability to track accountability? I'd like to see something that was on a per-user basis, maybe tied to the zope user, maybe not. There's been a ton of talk about a zope cvs product. I've been thinking about giving it a shot for a while now. I'm excited to see someone actually doing something about it.

Re: [Zope] Feeling like a newbie.. document id if statement?
dtml-if "_['id']=='index_html'" I wonder if someone would be kind enough to translate Rik's code into Enlish for me. I know that expressions inside "" are Python, but what is the function of the [] and _? Hm, I'm afraid this is a DTML trick (nothing more). I hope I can explain this right. Please correct me if I go wrong. Normally in DTML, you access variables in the current namespace with dtml-var id, which actually stands for dtml-var name="id" In an expression like the one used by J you actually use an expression, like dtml-var expr="id", in which case you do not get the id variable in the current namespace, but the actual value of the id attribute (property) of the object in the current namespace. The problem here is that the id of index_html is a python method (which is actually returned by dtml-var expr="id"). This will never be equal to 'index_html' as that is a string. The solution is to call the variable in the current object namespace by using it like a dictionary in the python expression dtml-var expr="_['id']". Because it's a method, you could (in this case) also use dtml-var expr="id()", in which case a string is returned (so that dtml-if expr="id()=='index_html'" will once again be useful. However, the _['id'] is preferred, because it will work on different objects and the id of most other objects is a string. For example: dtml-in "objectValues(['DTML Method', 'File'])" dtml-if "_['id'] == 'somestring'" do something nice /dtml-if /dtml-in would work, whereas dtml-if "id() == 'somestring'" would break if there are objects whose ids are not methods (assuming File is one of them, which I wouldn't know) So the different forms are (actually there are some more, but they do not matter here): dtml-var id dtml-var "id" dtml-var "_['id']" dtml-var "id()" dtml-var "_[id]" will give you an error Now that was probably more English than you'd hoped for hth Rik ___ 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 )

Would you please expand on the "make XPCOM components" task. By

constructed in Python from components interfaces that are accessible

Are you doing this by wrapping the the interface to the XPCOM Type

interesting approach is the way the ORBit-Python project reads CORBA
IDL files at run time and links directly to an ORBit ORB.)

it be possible to write the equivolent of the XUL completely in

[Zope] Reloading products
newbie time: I'm trying to write a product AlbumImage which extends Image to include a thumbnail. I was determined to slog it out without begging for help, but I've come up against a very strange brick wall. I'm getting problems with an import statement at the beginning of my product from OFS.PropertyManager import PropertyManager now then. I originally mis-spelled PropertyManager 'PropertyManageer' and got a traceback telling me it didn't exist. Fine. I changed it to the correct spelling, stopped and started my zope (n.b. is there any way of reloading a product without the tedium of stopping and starting zope?), and it still said 'no module named PropertyManageer'. So I tried changing it to ProoopertyManager, restarted Zope and sure enough the error was 'no module named ProoopertyManager'.

[Zope] RE: [Zope-Moz] Good news for Zope/Mozilla efforts!
Hi Michael --
Would you please expand on the "make XPCOM components" task.
I could, but you ask all the right questions, so I can just answer those.
By this are you adding new components, written in Python, that will be
accessible through the XPCOM interface?
Yes.
Would these components be
constructed in Python from components interfaces that are accessible
through the XPCOM interface?
Yes.
If this isn't the case then is does this
simply mean that Python can be used to assemble chrome using existing
XPCOM components.
It is the case, so "no". I read that last sentence as "can you use Python
to assemble existing components [written in e.g. C++]". While that is _a
part_ of the capability we're talking about, we are also talking about the
ability to have Python components act invisibly to the rest of Mozilla as
full-fledged XPCOM components (much like existing C++ components currently).
This is not unlike what one can do in PythonCOM currently in the Windows
world.
Are you doing this by wrapping the the interface to the XPCOM Type
Library or will you be parsing the XPIDL files directly. (Another
interesting approach is the way the ORBit-Python project reads CORBA
IDL files at run time and links directly to an ORBit ORB.)
The former.
By this do you mean that in the following XUL the value of "oncommand"
cannot be python code?
menuitem
value="Mozilla Help"
oncommand="window.openDialog('chrome://help/content/help.xul',
'_blank',
'chrome,all,dialog=no')" /
Correct.
or are you talking about not being able to embed Python instead of
javascript as in the following:
script language="javascript"
function doCMD(el) {
v = el.getAttribute("value")
if (v == "New") alert('New clicked')
elsif (v == "Open") alert('Open clicked')
else alert('Close clicked')
}
/script
...
menu class="menu" value="File" oncommand="doCMD(event.target)"
menupopup
menuitem oncommand="alert('New item alert')" value="New" /
menuitem value="Open" /
menuitem oncommand="alert('Close handler')" value="Close" /
/menupopup
/menu
That too. Both of those (really the same feature) require considerable
changes to the parser and to the DOM model, as documented in e.g.
http://www.mozilla.org/scriptable/agnostic.html. Again, that is part of our
long-term plan.
Instead of using XUL to write the menuitem... definition from the
first example or the menu... definition in the second example will
it be possible to write the equivolent of the XUL completely in
Python? That is, will the planned interface make it possible to build
an XPCOM component based application, such as the Mozilla browser,
entirely in Python.
In the long term, yes -- but not in the short term. In the short term
you'll have to use some JS in XUL files, although it will be able to
reference and call and manipulate components written in Python outside of
the XUL.
An interface between the Glade IDE and Mozilla has recently been
checked into Sourceforge. The documentation on MozGlade is weak.
The freshmeat announcment
http://freshmeat.net/appindex/2000/05/16/958529719.html hints at the

Komono IDE project.
I'll look into it, thanks for the pointer.
Will there be a mailing list for the project?
We're still working out how to proceed with respect to working with folks
outside of the company. I expect much of the discussion will take place on
existing Mozilla newsgroups.
What is your best guess
on when the "make XPCOM components" capability will be available for
testing from the Mozilla CVS?
Sorry, I'm unable to give a best guess at this point with any meat behind
it, especially when it involves integration with the main Mozilla tree, over
which we have no control.
While it's not a direct answer to your question, we are collecting email
addresses of those who want to be notified when Komodo is ready
(http://www.activestate.com/Products/Komodo.html).
I hope the above is helpful.

How difficult is it to implement case insensitive searches in this manner? Also, I've noticed that DTML documents don't appear to automatically add themselves to the Z catalog.

Re: [Zope] Subclassing from Custom Python Classes
Thank you for the useful information!!
I do have one more question regarding your persistence comments. How
does using a temporary name notify the Zope persistence machinery that
self.map has changed? Doesn't 'self.map=m' do nothing in Python if
one already did a 'm=self.map'? In the end, aren't they referencing
the exact same object? Hows does Zope know its different?
Thanks again,
Pete
On Wed, May 24, 2000 at 12:38:03AM -0400, Chris McDonough wrote:
You should also note that your subclass must obey the ZODB
persistence rules, which basically state that mutable sub-objects
should be treated immutably. For example,
self.bird='parrot' # OK
self.map['bird']='parrot' # NOT OK, will not trigger persistence
machinery
m=self.map
m['bird']='parrot'
self.map=m # OK, treats a mutable object immutably
What are these "persistence rules" and how come the second example is
ok? I thought in Python, when you assign "m = self.map" that m is
simply pointing to the same object as self.map and that any changes to
m affect self.map too? Does the "self.map = m" have any effect?
Don't they point to the same object?
It's a long story. :-) Attributes of Zope objects need to play by some
ground rules to be persistent. The description in the docs is sort of a
half truth. It works as described, but you can also do something like:
self.map['bird'] = 'parrot'
self._p_changed = 1
to trigger the persistence machinery. The "m=self.map..." stuff in the
example does the same thing. In either case you're bringing it to
Zope's attention that it needs to at some point re-write the object
referred to by "self" out to the ZODB. By doing the jiggery up there
where you use "m" as a temp object, operate on it, and then reassign
"self.map" to "m" in order to let Zope know you've really changed the
object and that you really want to write a new copy of it out to the
ZODB when it's convenient for it to do so. the _p_changed flag applies
to any Zope object, and just needs to be set true at some point during
the method to let the persistence machinery know that the object has
changed state.
In english the phrase "mutable sub-objects should be treated immutably"
means that attributes of the Zope object you're mucking with that can be
reassigned "in-place" (things you can append to like a list, or add
items to like a dictionary) should be treated as though they can't be.
So when saying (where 'self' is a Zope object):
self.mylist.append("foo")
This should be given special treatment, either by saying:
self.mylist.append("foo")
self._p_changed = 1
or
mytmp = self.mylist
mytmp.append("foo")
self.mylist = mytmp
I ask because I've already built my first product based on a custom
python class I wrote (its a router object that has methods to query
various snmp oids) based on a ZClass and I want to make sure that I am
not doing anything wrong.
In addition to the methods that query the oids, I store the results in
an instance variable of my Python class so I can cache the information
for a specified amount of time. Is this safe to do? Can I store
these values in my Python instance (self.), not a ZClass property?
Sure, just make sure you abide by the stuff above.
Also, What happens if multiple people activate my query method, do I
need to worry about them stomping over each other as the method writes
the results to the instance variables? Is there any record locking of
objects?
The ZODB will flag a ConflictError and will cause the second attempter
to retry. This is pretty normal, and your data won't get munged. Look
out, however, if you're really concerned, about "hot spots" that can
effect performance.
Lastly, since I couldn't really find any pointers regarding a builtin
Zope scheduler that is bug free, I need to write a small python script
that I can place in a cron job to run every ten minutes to call the
query methods of these objects so they update their cache instances.
Is there a link on how to get a regular Python script access to the
ZODB?
Yes... sort of. Try looking for a HowTo named "The Debugger is Your
Friend" by Michel Pelletier. That shows you how to use the Zope module
from inside python. It's simpler than you might expect. Here's an
example (make sure you shut down your Zope before you try this or it
won't work):
[chrism@opar chrism]$ cd Zope2.1.6/lib/python
[chrism@opar chrism]$ python
import Zope
app = Zope.app()
app
Application instance at 8455220
dir(app)
['Control_Panel', '__allow_groups__']
Play around inside Python, call methods on things, etc. This is a great
way to learn more about Zope.
