From 8160399a36eff62a49a066f16dea9140d877c5e8 Mon Sep 17 00:00:00 2001 From: Anand Avati Date: Wed, 26 Mar 2014 11:52:53 -0700 Subject: meta: (re-)Implement Meta translator 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 Reviewed-on: http://review.gluster.org/7509 Tested-by: Gluster Build System Reviewed-by: Harshavardhana --- xlators/meta/src/plugins/root-dir.c | 67 +++++++++++++++++++++++++++++++++++++ 1 file changed, 67 insertions(+) create mode 100644 xlators/meta/src/plugins/root-dir.c (limited to 'xlators/meta/src/plugins/root-dir.c') diff --git a/xlators/meta/src/plugins/root-dir.c b/xlators/meta/src/plugins/root-dir.c new file mode 100644 index 00000000000..bd6870b21d7 --- /dev/null +++ b/xlators/meta/src/plugins/root-dir.c @@ -0,0 +1,67 @@ +/* + Copyright (c) 2014 Red Hat, Inc. + This file is part of GlusterFS. + + This file is licensed to you under your choice of the GNU Lesser + General Public License, version 3 or any later version (LGPLv3 or + later), or the GNU General Public License, version 2 (GPLv2), in all + cases as published by the Free Software Foundation. +*/ + +#ifndef _CONFIG_H +#define _CONFIG_H +#include "config.h" +#endif + +#include "xlator.h" +#include "defaults.h" + +#include "meta-mem-types.h" +#include "meta.h" +#include "meta-hooks.h" + + +static struct meta_dirent root_dir_dirents[] = { + DOT_DOTDOT, + + { .name = "graphs", + .type = IA_IFDIR, + .hook = meta_graphs_dir_hook, + }, + { .name = "frames", + .type = IA_IFREG, + .hook = meta_frames_file_hook, + }, + { .name = "logging", + .type = IA_IFDIR, + .hook = meta_logging_dir_hook, + }, + { .name = "process_uuid", + .type = IA_IFREG, + .hook = meta_process_uuid_file_hook, + }, + { .name = "version", + .type = IA_IFREG, + .hook = meta_version_file_hook, + }, + { .name = "cmdline", + .type = IA_IFREG, + .hook = meta_cmdline_file_hook, + }, + { .name = NULL } +}; + + +static struct meta_ops meta_root_dir_ops = { + .fixed_dirents = root_dir_dirents +}; + + +int +meta_root_dir_hook (call_frame_t *frame, xlator_t *this, loc_t *loc, + dict_t *xdata) +{ + meta_ops_set (loc->inode, this, &meta_root_dir_ops); + + return 0; +} -- cgit
