...a linked list assertion with debug=y builds or memory corruption on debug=n ones. Fix by swapping the order the two kinds of table are torn down in. While at it, remove the condition in p2m_final_teardown, as it is already checked identically in p2m_teardown_hostp2m itself.

...hat would be related. Has anyone seen this before, can anyone suggest anything I might try? With both being unable to reproduce this at will and the lack of messages or log entries pointing to the problem I'm pretty much up against a wall.

Coverity generates false positives when read_atomic() and write_atomic() are called with pointers to objects smaller than 64 bits (because it can''t see that the 64-bit access in the switych statement is dead code). I don''t want to automatically suppress all ofthose, because read_atomic() and write_atomic() could still be called with mis-cast pointers, but for atomic_t accessors

Hey We have a static analyzer setup for Xen called Coverity. It allows the code to be inspected for bugs and such. Originally I setup this so that we could make sure that there are no bugs that cause security issues - and as such invited only folks on the security Xen mailing list. But there are other folks who I am sure would like to contribute and as Coverity is pretty amazing at analyzing

Does anyone know if patlooptest either doesn't work for fxo/fxs signaled channels or if you have to do it a different way? If I run ./patlooptest /dev/zap/25 60 with a config like: fxsks=25-32 fxoks=33-48 it gives me a bunch of output along the lines of: (Error 4071): Unexpected result, 254 != 255, 11 bytes since last error.

Hi, I recently posted about running a Rails app inside of a Cocoa application via RubyCocoa. I have a (very raw and ugly) proof of concept available: http://www.ldaley.com/dl/RailsInCocoa.dmg Also, a short write up about it: http://www.ldaley.com/2006/11/23/ruby-on-rails-dipped-in-cocoa/ To build and run the proof of concept, you will need RubyCocoa installed on your machine.

We are building a web-based application with Ruby on Rails and MySQL backend. The client now wants us to add various workflow features that will eventually expand into SOAP web services. These workflow features include tasks such as automatically sending reminders for due tasks, or if a particular set of information hasn''t been logged by a certain time to automatically send an email

Greetings -- I've got some sensor data of the form t1_1, t1_2 t2_1, t2_2 ... tN_1,tN_2 -- time intervals measuring starts and stops of sensor activity. I'd like to see whether there's any regularity in it. Seems natural to consider these data timeseries -- except most of the timeseries packages and models assume regular ones, with a fixed frequency. I wonder what's a
