Hi there,
We have released Poly 1.0p6. The change log is below.
Patch level six adds two more tools for extracting info from binary
logs (lx) and generating experiment reports (exprep.pl). Both are under
construction. We will add more functions and document the interface as soon
as we can. For now, you may try the following command to extract a few
useful "objects" from a binary log file:
./lx --prn_names yes --objects all,resp_tm_perc:50 /tmp/some.binary.log
This release also includes a couple of workarounds for known proxy
compatibility problems. Let us know if something is still broken.
Finally, because of the limited testing we had time for, we do not
call this release "stable" at the moment. We expect to catch up after the
bake-off.

P.S. 1.0p6 will not be used for workload generation at the bake-off. It can
be used for reading the bake-off logs and generating the reports though.
--------------- change log --------------
1.0p5 -> 1.0p6
19990310
- added "lx", a routine to eXtract objects from binary logs; also
mergers logs to support multiple client/server experiments
- added "exprep.pl" script to generate reports from binary logs
of several experiments (needs more work)
- replaced all ETag: headers with X-ETag (requests and replies);
ETag is not a request header and gets filtered out on some proxies
- added "Last-Modified: Wed, 18 Feb 1998 17:53:58 GMT" reply header
to cachable replies; some proxies may not cache replies otherwise
(a magic constant value should be eventually eliminated)
- changed the default for the "--log_size" option to 10KB
with no logging and 10MB with logging enabled
- various fixes to handle log buffer overflows; we now ignore all
new entries if the buffer is full (needs more work)
- fixed a lot of bugs in interpreting logged data (recording was OK?)
no program was interpreting logs so bugs stayed undetected
- mandatory phases should not stop even when too many errors;
we used to abort if that happens (needs more work to detect
error flood early as we used to)
- increased required verbosity level for "got N xactions..." message
to 2; a more detailed but less readable progress/goal message is
printed with a verbose level of 0.
