protocol: increase default group-cache-timeout to 300 seconds

2015-05-06T17:34:22+00:00

sssd uses 300 seconds by default too. There is no need to overload sssd
with requests that it would have cached.

geo-rep: Fix ignoring geo-rep safe errors

2015-05-05T06:15:21+00:00

Fix ignoring geo-rep safe errors in fuse layer
and also ignore logging in client translator
for mknod. Though it is rare, to happen with
mknod, it might happen with history crawl on
overlapping changelogs replay.

geo-rep: Don't log geo-rep safe errors in mount logs

2015-05-04T13:29:57+00:00

EEXIST and ENOENT are safe errors for geo-replication.
Since mkdir is captured in all the bricks of the changelog.
mkdir is tried multiple times as per the number of bricks.
The first one to process by gsyncd will succeed and all
others will get EEXIST.  Hence EEXIST is a safe error
and can be ignored. Similarly ENOENT also in rm -rf case.
And also gsyncd validates these errors and log them in
master if it is genuine error. This is up with
the patch http://review.gluster.org/#/c/10048/
Hence ignoring above said safe errors.

build: make contrib/uuid dependency optional

2015-04-10T11:39:52+00:00

On Linux systems we should use the libuuid from the distribution and not
bundle and statically link the contrib/uuid/ bits.

libglusterfs/src/compat-uuid.h has been introduced and should become an
abstraction layer for different UUID APIs. Non-Linux operating systems
should implement their compatibility layer there.

Once all operating systems have an implementation in compat-uuid.h, we
can remove contrib/uuid/ from the repository completely.

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.

mount.glusterfs: mounting volumes with volume files

2015-04-07T09:01:29+00:00

This is a patch for bug-1208676.

When using volume files to mount glusterfs volume,
this line is always true:

[ -z "$volume_id" -o -z "$server_ip" ] && {

That's because at this place, $volume_id and $server_ip are
set only and only if the $volfile_loc file was unreadable
or undefined.

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.
