* Avoid conflict between contrib/uuid and system uuidEmmanuel Dreyfus2015-04-041-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* meta: (re-)Implement Meta translatorAnand Avati2014-05-051-0/+370
The meta translator exposes details about glusterfs itself in the form of a virtual namespace. Loading the translator on the client side creates the meta virtual view under $mntpoint/.meta by default. The directory is not listed (even with ls -a) and can be accessed by doing a "cd /mnt/.meta" Change-Id: I5ffdf39203841a9562a8280a1f79dc76d4dded5d BUG: 1089216 Signed-off-by: Anand Avati <avati@redhat.com> Reviewed-on: http://review.gluster.org/7509 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Harshavardhana <harsha@harshavardhana.net>
