No, that's it. And done by setting "logfile_rotate 0" in squid.conf so
no code changes is needed for it.

Sequence is:
1. Rename log files.
2. Tell Squid to reopen log files (-k rotate)
3. Optionally wait a little for Squid to react.
4. Process the logs (gzip etc).
Normally compression is only done on the older logs already rotated in
last rotation, so late writes is usually not a big deal.
If compression is done immediately after rotation then there is a slight
risk that some log entries may be lost, especially in cache.log.
