Re: [Zope-dev] PAU question - how to I handle roles on principals

Thanks Kevin Hi, I suppose you have to use a PrincipalAnnotations utility, which can store anything about principals which are not in the zodb (metadata, roles, etc.).

Re: [Zope-dev] Runaway processes
Hi Jim, first of all, thanks a lot for your quick response. On Thursday 06 December 2007, Jim Fulton wrote: > - You should avoid runaway processes. :) I'm actually quite serious. Yes, we are trying hard. :-) We are currently using lovely.remotetask to export those calls even to a different server, where we run the code in forked subprocesses. After having played for a day with this problem, I came to the following conclusion: Python assumes that all used C-libraries are wrapped in a way that they are non-blocking and cannot lock up. When forking, you better know what you are doing. Based on your comment, I think you agree. :-) > - You can run multiple processes and monitor their progress -- killing > processes that are stuck.

Wow, zc.z3monitor -- and zc.ngi which I looked at too -- are very cool. How useful! I have been following the checkins and had an idea of what it was about, but it is definitely cooler than I thought. :-) However, some code calls a blocking operation, zc.z3monitor will be locked up as well. I guess then I only have to check whether I get connectivity or not. ;-) > - It might be interesting to see if Java or .Net give better control > over threads.

Java has a lot more control over threads, but I still have found complaints that they left out some features for portability reasons. I could not immediately find an answer on whether blocking, run-away C-calls are handled correctly. I talked to Roy Mathew, a once at a time Java guru, and he said that Java has a time-limit it gives each thread for doing some work. (I am not supposed to quote him on that. ;-) So if that is true, then Java does not have the problem. Roy did mention, though, that debugging locked threads in Java is a common skill after you reached a certain level of Java Zen. I looked yesterday quiet a bit at Win32 threads. That part of the Win32 kernel seems pretty well thought out and from what I can tell you can have quiet a bit of control over the threads. Again, I am not sure how hanging threads are handled.
