Re: [Zope] Accessing Zope site through network
Do you have a firewall running on that machine? Is it blocking? Remember also, it's port 8080 by default, but you probably know that because you logged in locally. (I assume) You can ping that machine over the network,right? Try login with IP not name, too. http://yourip:8080 or example: http://192.168.0.1:8080 Just thinking out loud now... good luck!

[Zope] ZASync method calls
Hi! I'm having a really complicated problem that I don't know how to put into words properly, because I'm really vague on what's causing it and the setup is highly involved; I would be _really_ glad if someone could help me out with this: I have a ZOPE instance (connected to a ZEO server) running a custom method call wrapper that decides (based on the method's arguments) to run a method asynchronously using zasync (as well as some other stuff that I think isn't important in the context of my problem). All this has been tested. For various reasons, the method call's path is approximately as follows: 0. Method call using a generic Python method 1. Python code - resolves the method's location and name using ZOPE methods 2. Method dispatcher (called via ZOPE): dispatches synchronously or asynchronously, using zasync, zope_exec and putSessionCall; the method called is again a ZOPE method that calls the final method as another ZOPE method The apparent massive indirection cannot be avoided (for rather complicated reasons). Everything is supposed to be highly generic. My problem is this: if I use a test method that dispatches such an asynchronous method that is supposed to change an instance variable (the class is persistent) and run for ten seconds, then wait for fourteen seconds and see if the method has run (check the instance variable) synchronously (while the asynchronous method is supposed to work in the background), I find the variable unchanged; further checks (using print statements) confirm that the asynchronous method indeed doesn't run until my assertion fails, even if I give it a lot of time. If I disconnect both - run the long running method asynchronously, then run (via ZOPE directly, not from within the same method call) a synchronous method that waits for fourteen seconds and checks the variable, the asynchronous call works just fine (even though both run alongsinde for a time). It isn't the number of threads available to the zserver, I've increased that and nothing has changed. Manual tests of asynchronous methods also don't show anything wrong with my zasync setup. I can only assume that the asynchronous method is _started_ only _after_ the caller has finished. Is there a reason for that, and can I circumvent it? Or am I completely wrong and something else isn't working? I'm on Windows XP SP2, ZOPE 2.7.6, Python 2.3.5 with Twisted installed.

I guess my thought it that I want everything to happen normally with
the PUT except no object creation (which seemed to occur where I had
commented it out) of the PUT method. My workflow script and method
from a tool still needs the content type and body for processing so
overriding the original methods seemed a reasonable way to go.
I'm hoping to get something together enough to test today or tomorrow.

You do use a "PUT" function (!) but you do not define it.
Definitely, this will fail...

"SQLConnectionIDs" does not have an explicit security declaration. Therefore, it is protected by the folder's "object permission". Looks like the visitor does not have this permission.
