glusterd: fail vol set when value = empty string/string with all whitespaces

2012-12-10T22:18:17+00:00

PROBLEM:

'volume set' operation accepts empty strings and strings containing
all whitespaces for value. The result - subsequent attempts to start
glusterd fail.

FIX:

Added relevant checks in xlator_option_validate_* functions in options.c
and in conversion functions in common-utils.c to invalidate wrong option
values.

Revert "glusterd, cli: Task id's for async tasks"

2012-12-04T23:59:52+00:00

This reverts commit ed15521d4e5af2b52b78fd33711e7562f5273bc6

Strangely, the test scripts are "silently" passing for failures too. Reverting patch for now.

glusterd, cli: Task id's for async tasks

2012-12-04T22:44:36+00:00

This patch introduces task-id's for async tasks like rebalance, remove-brick and
replace-brick. An id is generated for each task when it is started and displayed
to the user in cli output. The status of running tasks is also included in the
output of "volume status" along with its id, so that a user can easily track the
progress of an async task.

Also,
 * added tests for this feature into the regression test suite.
 * added a python script for creating files, 'create-files.py', courtesy
   Vijaykumar Koppad (vkoppad@redhat.com) into the test suite.

features/locks: implement fgetxattr and fsetxattr

2012-11-28T06:54:27+00:00

implement xattrs for GF_XATTR_LOCKINFO_KEY, which will be used
for posix-locks migration from old to new graph after a switch.

fgetxattr (fd, GF_XATTR_LOCKINFO_KEY) will return a dict.
This dict has a serialized dict stored for key
GF_XATTR_LOCKINFO_KEY. This serialized dict in turn has fdnum
value of locks acquired on this fd with modified pathinfo
(containing hostname and base directory components) as key.

fsetxattr (newfd, GF_XATTR_LOCKINFO_KEY, dict) has following
semantics. dict can be the result of a previous fgetxattr with
GF_XATTR_LOCKINFO_KEY. In that case, a dict_get on dict
constructed using serialized buffer is done on modified pathinfo
as key. If a value is got, that value is treated as fdnum and for
every lock l on newfd->inode we do,
      if (l->fdnum == fdnum) {
         l->fdnum = fd_fdnum (newfd);
         l->transport = ;
      }
