You know what I mean, “This code should really have been designed to do XYZ.” Or “This module shouldn’t have to talk to that module.” I figured I’d try to record some of the [...] Phil Harmon wrote a blog entry over a year ago ( Solaris Threads Tunables ) where he mentioned a list of tunable parameters that you can use to fiddle around with the implementation of Solaris libthread. You can fine tune the spin-lock timeouts, and other timing details. But one of the flags that he mentioned is [...] One of the things that’s really hard about debugging threaded programs is tracking down which threads own which locks, and figuring out which locks they are supposed to own. In other words, synchronization bugs. The most difficult symptom to debug is data corruption, because it’s very hard to track down exactly where things start to go [...] I’ve been working in my spare time on the idea of converting dwarf debugging information into XML so that I can format it as XHTML using a stylesheet, and so I can check it using a Schema of some sort. When I started fiddling today I assumed that using a DTD was the way [...] |
