[Zope-dev] Zope 2.3.3 back-downgrade
Hi! If I use PythonScripts, are there any serious problems with downgrading a Zope-2.4.3/2.4.4 to 2.3.3? I cant remember if 2.3.3 had pythonscripts, but i recall that there was a product that later became officially pythonscripts... Are there any other incomaptibilities that anyone knows about?

[Zope-dev] FileSystem based products markup.
Yo,
We have a file system based product, and some dtml-methods are defined the
usual way
myMethod=DTMLFile('myMethod',globals())
We want our webbies to be able to add some eye-candy. But how would they
go about if they want to add some images ?
Remember: THEY ARE WEBBIES, so it has to be really easy and simple and
changeable, so no
myImage=ImageFile(..)
solutions are possible.
Ideas appreciated
Sloot.

FYI: This list is for messages concerning development of Zope itself, not
developing with Zope.
Anyway, to answer your question, If the classes that your product defines
support acquisition (the subclass Acquisition.Implicit or some other base
class that does, such as SimpleItem.Item) then you can put the Images in the
ZODB anywhere you like, so long as they can be acquired by the instances of
your product class(es).
Another idea would be to make your instances ObjectManagers (just subclass
OFS.ObjectManager.ObjectManager) and the webbies can put the images
directly in the instances. They would need to know what ids to use so that
the dtml could pick them up properly.
To make the dtml work without the images you can sprinkle in missing
attributes so they fail gracefully if the image is not found:
dtml-var name=some_image missing
Yet another idea (if the images are global to all instances of the product)
would be to create a filesystem directory in the product (or anywhere on the
server readable from Zope) that the webbies can save their image files
directly into. You could then code the product so that it scans the directory
and loads each image using the ImageFile method. The id could be based on the
file name. Or, just make it pull them from the directory on the fly by
defining a getImage method or somesuch that takes a file name, and loads it
on demand. That way no code changes would be necessary to add new images to
the product.

[Zope-dev] Document Library Question
I have modifiedthe DocumentStore.py file. After making the necessary corrections, I have noticed that when I use the DocumentLibrary, the modificationsstill have not beencorrected. what I´m doing wrong?. Perhaps somebody had implemented what I´m trying to do: to make DocumentLibrary able to upload multiple files ( not only one by one), in this case please send me an email back.

AJ == Andreas Jung [EMAIL PROTECTED] writes: AJ Does this problem persist when you remove the 3rd-party products AJ ? Are you running Zope with enabled garbage collector ? Just a reminder that you *should* be running with the garbage collector enabled. We are aware of no current bugs in the garbage collector, which has been in use since Python 2.0. If you see a crash and the gdb stack trace points to the garbage collector, it is almost surely a sign of memory corruption caused by bugs elsewhere in Python or in a C extension. You can prevent those crashes by disabling the garbage collector, but you are more likely to get bizarre errors or storage corruptions since the interpreter memory is corrupted.

Re: [Zope-dev] Zope 2.4.4b1 dumps core
Python 2.1.2 has some extra safety checks that will immediately detect the stack overflow bugs that caused problems with PythonScripts before 2.4.4. The fact that you're seeing crashes in the garbage collector and not assertion failures in Python/ceval.c makes me think the problem isn't with the PythonScripts. I wouldn't rule it out completely, but it seems unlikely. Does the community have any Zen about how to narrow down bugs like this? It seems a daunting task, in general, because it's not obvious what particular request exercises the bug, and the error report doesn't come until long after the bug occurs. I wonder if you could crank up the garbage collection frequency -- either use gc.set_threshold() to see the threshold very low or add an explicit call to gc.collect() after each request. If you're lucky, this would cause the bug to be detect -- like right after the request that exercised the bug. Where exactly would you put the gc.collect() call to make this work?
