* Improve behavior when out-of-order record detectedMac Mollison2010-12-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order to sort records from different files into a single stream (in order of timestamp), unit-trace uses per-cpu buffers; the length of the buffers was previously hardcoded. If that length proved insufficient (resulting in out-of-order records), before this commit, unit-trace produced a FATAL ERROR and terminated. Now, unit-trace merely keeps a record of all out-of-order records and prints a warning at the end, listing them. The motivation for this change was the observation that at least some times, grossly out-of-order errors were at the very beginning of the trace (e.g. task system release), so they don't really matter. If we know the IDs of the records that are unordered, we are able to check (with the -o output) to see if their misordering actually matters or not. Moreover, the buffer size can now be specified with -b, and the previously hard-coded value (200) is the default. Making this number smaller greatly improves runtime, and vice versa. I suspect that further investigation into the problem of sorting records will show that the current method is overkill; down the road, we may be able to replace this method with something much faster. (The current method has the advantage that it is extremely scalable, but I don't think that pays off for the size of traces we typically examine.)
