dht,posix: support for case discovery

2013-06-08T21:51:22+00:00

This is support for discovering a filename in a given directory
which has a case insensitive match of a given name. It is implemented
as a virtual extended attribute on the directory where the required
filename is specified in the key.

E.g:

  sh# getfattr -e "text" -n user.glusterfs.get_real_filename:FiLe-B /mnt/samba/patchy
  getfattr: Removing leading '/' from absolute path names
  # file: mnt/samba/patchy
  user.glusterfs.get_real_filename:FiLe-B="file-b"

In reality, there can be multiple "answers" as the backend filesystem is
case sensitive and there can be multiple files which can strcasecamp()
successfully. In this case we pick the first matched file from the first
responding server.

If a matching file does not exist, we return ENOENT (and NOT ENODATA).
This way the caller can differentiate between "unsupported" glusterfs
API and file not existing.

This API is used by Samba VFS to perform efficient discovery of the real
filename without doing a full scan at the Samba level.

glusterd, cli: Task id's for async tasks

2012-12-19T21:32:49+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.

This patch reverts the revert commit 698deb33d731df6de84da8ae8ee4045e1543a168.

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

This reverts commit ed15521d4e5af2b52b78fd33711e7562f5273bc6

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

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 = ;
      }
