[DTML] I give UP!!!! (well, almost... ;))

I've been trying to figure this out, and I've given up (at least for the day...:(). How do I change the value of a temporary variable that I created with a namespace method? e.g.:      ...      ... I tried the following and they don't work :   I've tried to look at the dtml of all the products I've d/l'ed and also at the proto-FAQ but I haven't found one that exactly does this. Thanks in advance to any DTML guru(s) who can help me this... Butch Landingin butchland(a)yahoo.com _________________________________________________________ DO YOU YAHOO!?

It will continue to accept new connections. If all those connections need to wait for a single-threaded database server, then you don't gain much by running in multi-threaded mode. >Even if ZHS doesn't block completely, more and more queries can pile up. Right. >ZHS has no capability to limit the number of simultaneous threads, Yes, but ZServer does.

While it would appear at first that running a multi-threaded >ZHS would be a win (allows short-running stuff that can be handled >completely by the published module to complete), I think the bad (nay, >catastrophic) failure mode suggests otherwise. I'm not sure how things would work out in real life. I suggest you do some tests to see how things perform under a heavy load. If ZHS is creating too many threads, you might want to switch to ZServer. If you don't like running alpha software, you might want to change ZHS to use a thread pool, which wouldn't be very hard. (Not that I'm volunteering ;-) Otherwise, you might want to start caching results of your database queries, this could potentially help you quite a bit, no matter what server mix you end up using. Finally, I have no idea what your database server is like, but if there are any easy ways to make it multi-threaded or simply faster, go for it ;-) It sounds like this is where your performance bottleneck lies. Good luck. -Amos

The Spanish Aquisition

Zopistas, I am trying to reference a property of a Folder that is in a totally spearate hirearchy of Zope. When inserted below the folder Iwish to grab the property of it works fine, but when moves elsewhere it dies.    name is the property, and candidate1 is the folder id. I have tried _.namespace and the #with and #in tags, all have the same problem. Here is the traceback  Do I have to know the folder that separates the hirearchy and put that in somewhere? Zope-on!

Skip> Will I need to make changes to Fredrik Lundh's XML-RPC code to Skip> make this work? Amos> I don't know much about this code, but I doubt it is causing any Amos> concurrency issues or otherwise for you. I guess what I meant to say is will I need to modify the I/O that XML-RPC does to take advantage of Medusa's multi-threading I/O? Alternatively, will not making a change reduce or eliminate the multi-threading? Fredrik's xmlrpclib module uses vanilla httplib to communicate with the server. Does loading asnycore/asynchat do something to fiddle with the I/O in standard packages or do you have to explicitly modify them to use it?
