quota/disperse: handle inode quotas in xattr aggregate

2015-04-14T05:01:18+00:00

with the inode quota feature, quota size is now
increased from 64bit to 192bits which contains
values of 'file size', 'file count' and 'dir count'

This change in quota size xattr needs to be handled
in disperse xattr aggregation

cluster/ec: Entry self-heal fixes

2015-04-13T11:01:39+00:00

- Directory deletion should always happen with 'rm -rf' flag, otherwise the
  call may fail with ENOTEMPTY.
- Instead of doing an explicit 'link' call, perform mknod call with
  GLUSTERFS_INTERNAL_FOP_KEY which acts as 'link' if the
  gfid already exists.

cluster/ec: Fix readdir de-itransform

2015-04-11T09:11:15+00:00

Problem:
gf_deitransform returns the glbal client-id in the complete graph. So except
for the first disperse subvolume under dht, all the other disperse subvolumes
will return a client-id greater than ec->nodes, so readdir will always error
out in those subvolumes.

Fix:
Get the client subvolume whose client-id matches the client-id returned by
gf_deitransform of offset.

cluster/ec: Fix iobuf mem leak

iobuf_get and iobref_add implicitly
ref the iobuf.

Hence, it is necessary to unref iobuf
before setting it to NULL.

libglusterfs/syncop: Add xdata to all syncop calls

2015-04-08T15:14:59+00:00

This patch adds support for xdata in both the
request and response path of syncops.

Few calls like lookup already had the support;
have renamed variables in few places to maintain
uniformity.

xdata passed downwards is known as xdata_in
and xdata passed upwards is known as xdata_out.

There is an old patch by Jeff Darcy at
http://review.gluster.org/#/c/8769/3 which does the
same for some selected calls. It also brings in
xdata support at gfapi level.

xdata support at gfapi level would be introduced
in subsequent patches.

ec_manager_xxx() function for [f]set/[f]remove xattr is exactly same except the
reporting part. So moved that to common function and use same
ec_manager_xattr() function for all these fops.

cluster/ec: Refactor inode-writev

2015-04-07T05:35:07+00:00

All _cbk() functions in inode-write.c do same things, i.e. store
op_ret/op_errno, stat structures if they are available and combine them.  Moved
this common operation into one function ec_inode_write_cbk() and made all the
other _cbk() functions to use this instead.

Avoid conflict between contrib/uuid and system uuid

2015-04-04T17:48:35+00:00

glusterfs relies on Linux uuid implementation, which
API is incompatible with most other systems's uuid. As
a result, libglusterfs has to embed contrib/uuid,
which is the Linux implementation, on non Linux systems.
This implementation is incompatible with systtem's
built in, but the symbols have the same names.

Usually this is not a problem because when we link
with -lglusterfs, libc's symbols are trumped. However
there is a problem when a program not linked with
-lglusterfs will dlopen() glusterfs component. In
such a case, libc's uuid implementation is already
loaded in the calling program, and it will be used
instead of libglusterfs's implementation, causing
crashes.

A possible workaround is to use pre-load libglusterfs
in the calling program (using LD_PRELOAD on NetBSD for
instance), but such a mechanism is not portable, nor
is it flexible. A much better approach is to rename
libglusterfs's uuid_* functions to gf_uuid_* to avoid
any possible conflict. This is what this change attempts.
