      More work on getting ready to switch over to apache 2.2 ... Move the · 96bc3d62
      Leigh B Stoller authored
      different versions into v1/v2 subdirs, since I did not like the
      Add new version of the ops httpd.conf file, again taken from Dave's
      linux-port branch, and then whacked on.
      Add utah versions of the boss/ops config files and a utah target.
      These will probably get removed later when we switch over, but I do
      not want to lose the work I did to merge in the local hacks.

      Add hgmail script · 89982747
      Ryan Jackson authored
      hgmail is like our gitmail script, only for Mercurial instead of git.
      Filtering emails based on the branch doesn't work correctly, so it has
      been disabled for now.  Filtering based on path should still work

      Fixup the last commit so newer-style linux shaping with netem works. · 72fb9e3a
      David Johnson authored
      I didn't know this initially, but it turns out that with newer netems,
      you can't add another netem qdisc instance (nor an htb instance)
      inside another netem instance.  The linux maintainers removed
      "classful" qdisc support from the netem qdisc (which makes it
      possible for another qdisc to be "nested" inside a netem qdisc)
      because 1) netem couldn't even nest an instance of itself inside
      itself -- which isn't stricly necessary for us because we can do
      both delay and plr in one netem instance), and 2) because apparently
      non-work-conserving qdiscs already didn't work inside netem (a
      work-conserving qdisc is one that always has a packet ready when its
      underlying device is ready to transmit a packet -- thus, a
      bandwidth-shaping qdisc that might not have a packet ready because
      it's slowing down the send rate is non-work-conserving), and 3) to
      support code cleanups.
      So -- what this means for us is that by using modern netem, we are now
      doing bandwidth shaping first, then plr and delay.  With our old
      custom kernel modules, we were doing plr, delay, then bandwidth.
      I talked this strategy over with Jon (because adding classful support
      back to netem is nontrivial and defeats the point of trying to use
      what's in the kernel directly without patching it more), and we believe
      it's ok to do -- one because it doesn't always change the shaped rate
      from the old way we used to do things, and second because using these
      params *in tandem* to do link shaping is kind of a poor man's way
      of actually modeling real link behavior -- a la flexlab.
      So we'll just document it for users, call it beta for now, and test
      it against the old way and BSD.  If it looks reasonable, we'll stick
      with it; otherwise we'll look at reviving the old style.
