I've finally committed changes to Lusca which migrate the HTTP Header management routines away from individual malloc/free calls per HTTP Header entry to (hopefully!) one malloc/free for every N. (N being tunable, of course.)
A lot of incremental preparation work was required in the HTTP parser to tidy things up enough to (hopefully!) minimise any impact on stability and functionality.
There really isn't all that much noticable improvement unless you're working on small, embedded platforms with slow CPUs. It's more of a precursor to further optimisation and reorganisation work. The cumulative effect will be worthwhile.
I've released a tarball with the work - r14674 - which also includes a handful of ATF unit tests in the test-suite/atf/ subdirectory.
I'll likely next work on reorganising some more of the FTP and HTTP protocol specific code which can be migrated out of src/ . I'd like to then spend some more time writing unit tests before (hopefully!) finishing off the IPv6 related DNS changes in preparation for more IPv6 related tomfoolery.
