Hi there,
Web Polygraph 2.6.3 is available. The change log is attached.
http://www.web-polygraph.org/downloads/
This is a minor release that fixes a few 2.6.2 bugs and polishes
SrvLB-L7 workload. One of the fixed bugs led to floating point
exceptions at start-up time for some workloads. Please read the change
log for other details.
Those of you using Polygraph for proxy caching tests, including
fourth cache-off preparations, please note that version 2.6.3 fixes an
important bug that may affect your hit ratios.
Thanks,
Alex.
------------- change log -----------------
2.6.2 -> 2.6.3
20010627
- emit (errUnreachContType) "unreachable content type" when an
embedded content type cannot be found on the [visible] server that
hosts the container object; Polygraph can only handle embedded
objects that reside on the same visible server as the container
- use the same content distribution for all L7 servers (except
for the URL extension) so that all servers will get similar
load
- when server's direct_access probabilities are specified manually,
use them and do not compute our own
- added "byte.rptm.mean", [milliseconds / kilobyte] object to Report
Generator. The object value is visible in make_report as "byte"
table entry in the Response Time table and as the byte_rptms plot.
- replaced --rng_seed option with two new options: --global_rng_seed
and --local_rnd_seed. Both default to 1. All processes within a
test must have the same --global_rng_seed value to correctly
generate "global" information such as a URL extension for the same
object ID. All processes within a test should have different
--local_rnd_seed settings to avoid lock-step behavior of things that
should not be synchronized.
- do not print "Potential problems" header if no problems are detected
by make_report
- when generating a public miss, use local public world slice
only; using remote slices creates race condition for
generating a miss with the corresponding remote agent; these
race conditions lead to buggy offered hit ratio
- W2K select(2) fails if no FDs are passed to it (i.e., all FDs sets
are empty)
- fixed fixed a very old bug (again) that, under certain conditions,
left some FDs ignored by select(2); the earlier fix was ineffective
- fixed ceil() workaround once again: the earlier fix was ineffective
