glusterd: run 'volume top read-perf/write-perf' in different thread

2011-09-20T05:00:25+00:00

Runs the 'volume top read-perf/write-perf' operations in a different
thread without blocking glusterd. Prvents glusterd from being
unresponsive when large values of 'bs' and 'count' are given.

Also increase cli timeout for top/profile commands , from 120s to 300s
to allow large i/o top read-perf and write-perf to return result.

glusterfsd: enable max fetch attempts

2011-09-19T06:45:36+00:00

Enables usage of 'volfile-max-fetch-attempts' option of glusterfsd.
Also, adds an option to 'mount.glusterfs' for setting the max fetch attempts.
For a server with multiple ips, each call to gf_resolve_ip6() returns a
different ip. Since gf_resolve_ip6() is called for each fetch attempt,
this change also enables rrdns support for gluster.

add --user-map-root option

2011-09-12T13:22:51+00:00

This makes client fake that given user is a superuser,
by changing FUSE requests coming with uid of user so that uid
is set to 0.

User can be given in numeric form, in which case it's treated
as an uid directly, or else it's tried to be resolved to an
uid with getpwnam(3).

Implies --acl.

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 :-)
