Photo Product Release
by Andrew 12 Nov '99

12 Nov '99

The Photo product allows the user to view an image at their preferred display size. The Photo product also automatically produces a thumbnail. The Photo product works by resizing the image after upload using PIL. Thereafter, the user can set their optimum display size as a parameter in the URL. The default display sizes correspond to all popular display sizes, including webtv. Displays can be added, removed and resized using DTML. This release of the Photo product is an alpha version and is intended for developers only. The DTML methods, web management screens and properties may all change before the first stable release. An upgrade path may not be provided. Please send comments and feedback to andrew(a)apl-software.com Drew

RE: [Zope-dev] string functions - need a how-to... joining two properties
by Digital Hyakugei 12 Nov '99

12 Nov '99

Once again, i have managed to answer my own question - here you go if you were wondering. <dtml-call "REQUEST.set('t1', 1)"> <dtml-call "REQUEST.set('t2', 2)"> Integer addition. <dtml-call "REQUEST.set('t3', t1 + t2)"> <dtml-var t3> gives you 3 string addition <dtml-call "REQUEST.set('t3', _.str(t1) + _.str(t2))"> <dtml-var t3> gives you 12 got it?

string functions - need a how-to... joining two properties
by Digital Hyakugei 12 Nov '99

12 Nov '99

And, again, questions... lets say i have some properties that i want to concatenate. they are both int's (or not, i'm sure i will want to do this with strings too at some point) that i would like to cast to strings. propA = 1 propB = 2 lets say that i want to be able to do something like propC = string(propA) + string(propB) which should result in propC = "12" I've *read* about string.join() but am unable to make it work... Any help would be great!!! thanks again! j

Writing results directly back to browser
by David S. Harrison 12 Nov '99

12 Nov '99

I have an external method that is capable of generating a PNG image in response to some input data. I would like to use this in the context of Zope to display a computed image on the fly. I am looking for suggestions on a couple of fronts: how can I wire this infrastructure into DTML and how does one write directly back to the browser from an external method? Here are my first guesses on both fronts. For DTML, my thinking is along the following lines: <IMG SRC="GenerateGraphics"> Here, I imagine that "GenerateGraphics" is an external method. I read somewhere (although I can't recall where), that an external method can take RESPONSE as an argument. So, on the second front, I am imagining that the external method uses RESPONSE to set the content type and then writes the results using the RESPONSE.write() method. Am I on the right track here?

Performance?
by Lalo Martins 12 Nov '99

12 Nov '99

A friend (owner of the site where we will plug our Zope machine) has being conducting some benchmarks and found Zope+Apache to be a lot faster than Zope-z2. Why? Is there any way to improve it? Is there any other webserver that is not so much of a pain to configure and overkill to run, that can make Zope run faster? Hmm... this should be on zope, not zope-dev :-) let's fix it: Is there anything we can do to improve z2? Or to make Zope work nicely with one of the ``lightspeed'' webservers such as boa?

Best way to do access logging?
by Andrew Wilcox 12 Nov '99

12 Nov '99

I'm interested in doing some access logging for my Zope site -- a record that such and such an authenticated user accessed such and such a page. Anybody have an access log product already? Where is the best place to hook into the page serving process to grab the user name and URL when a page gets served? Any issues with storing the log in the ZODB? I can send it out to a SQL database if necessary, but would prefer to keep it within Zope (and more portable) unless there is a good reason not to. Thanks! Andrew

Zope 2.1.0 beta 1 caution - please read
by Brian Lloyd 11 Nov '99

11 Nov '99

Hi all - We (DC) have run across a bug in the 2.1.0 beta that has given us some grief on the zope.org site, and I wanted to post a caution to those folks currently using the beta. In short, if you are doing any ZClass development where your ZClasses are based on Python base classes that are still in development (e.g. you are updating the Python base classes at times), there is a risk of getting a non- unpicklable object stuck into your object database. While the sequence of events required to cause this is pretty arcane, it can potentially be a real pain to recover from. So, if you are doing active ZClass development in 2.1.0b1 we strongly suggest that you either go back to 2.0.1 or take a break until tomorrow or Monday (I hope to have a 2.1.0 b2 ready that resolves this by then). If this is too painful (or you're hardheaded or just like living on the edge :) at least be sure to back up your Data.fs regularly just in case.
