[Gluster-Maintainers] Update on experimental branch (was Re: Jenkins build is back to normal : experimental-periodic #21)

[Amar Tumballi]

Experimental branch is back to successful build now. So I think its a good
time to update everyone about it.

Currently the branch has changes for:


   1. Added new on wire XDR changes.
      - All is working as expected with newer protocol.
      - So, if there is a change required for 4.0, I encourage everyone to
      propose it and send a patch so we can test it out.
   2. Changes in STACK_WIND/UNWIND to measure count and latency.
   3. A separate way to dump metrics
   - Similar to statedump, but only metrics, ie, a key and a value (as
      int/float) as entries in the file.
      - Some more improvements planned to provide functions in xlator_t
      itself for all translator to dump their private metrics if any.
      - I got a project going to draw these metrics in graphite/grafana @
      https://github.com/amarts/glustermetrics
      4. Subdir mount
      - Still waiting for authentication handling in
      xlator/protocol/auth/addr to send it to master.
      - Will take CLI changes after handling auth, thought for now is, same
      auth.allow volume set option can be reused in early state.
      5. New discover fop.
      - Currently its implemented at xlator_t, defaults and all the place.
      - Saw major regressions with DHT / AFR by using it.
      - Hence reverted the consumption of the discover fop for now.
   6. Global Inode table.
      - Most of the work was done and changes were present mainly in
      inode/fd files of libglusterfs.
      - Saw issues with regression tests, and some behaviour at the moment,
      and have reverted the patch.


Also it has one patch from Hari on tier add-brick/remove-brick.


Considering I don't have more traffic on the branch yet, I am planning to
branch out from master and rebasing all these changes on master again to
stick with 3 months branch out timelines.
Regards,
Amar
