XDR: cli-glusterd xdr consolidation

2011-11-16T09:42:29+00:00

By using only 1 xdr struct for request and 1 xdr struct for response,
we will be able scale better and also be able to parse the o/p better

For request use-
        gf1_cli_req - contains dict
For response use-
        gf1_cli_rsp - conains op_ret, op_errno, op_errstr, dict

Rewrite of glusterd_volume_brickinfo_get in glusterd-utils.c
An additional argument to glusterd_volume_brick_info_get_by_brick
and glusterd_volume_brickinfo_get enables matching brick path in
two ways: Complete or partial(ancestor and descendent paths matched).

support for de-commissioning a node using 'remove-brick'

2011-09-13T09:10:12+00:00

to achieve this, we now create volume-file with
'decommissioned-nodes' option in distribute volume, then just
perform the rebalance set of operations (with 'force' flag set).

now onwards, the 'remove-brick' (with 'start' option) operation tries
to migrate data from removed bricks to existing bricks.

'remove-brick' also supports similar options as of replace-brick.

* (no options) -> works as 'force', will have the current behavior
         of remove-brick, ie., no data-migration, volume changes.

* start  (starts remove-brick with data-migration/draining process,
          which takes care of migrating data and once complete, will
          commit the changes to volume file)
* pause  (stop data migration, but keep the volume file intact with
          extra options whatever is set)
* abort  (stop data-migration, and fall back to old configuration)
* commit (if volume is stopped, commits the changes to volumefile)
* force  (stops the data-migration and commits the changes to
          volume file)

Eliminate many "var set but not used" warnings with newer gcc.

2011-09-08T06:48:01+00:00

This fixes ~200 such warnings, but leaves three categories untouched.

(1) Rpcgen code.

(2) Macros which set variables in the outer (calling function) scope.

(3) Variables which are set via function calls which may have side effects.

modify to the way we used XDR definitions files (.x files)

2011-09-07T17:48:52+00:00

Earlier:
step 1: copy the existing .x files to /tmp
step 2: generate '.[ch]' files using 'rpcgen .x'
step 3: check diff with the to the existing files, add only your part
        of changes back to the original file. (ignore other changes).
step 4: there is another file to write wrapper functions to convert
        structures to/from XDR buffers, update it with your new structure.
step 5: use these wrapper functions in the newly written procedures.
step 6: commit :-|

Now:
step 1: update (mostly adding only) the .x file
step 2: run '/extras/generate-xdr-files.sh .x' command
step 3: implement rpc procedure to handle the request/response.
step 4: commit :-)
