Got rid of InodeDB. This feature was optionnal and i have never heard of
2007-04-27 Benoît Dejean <benoit@placenet.org> Got rid of InodeDB. This feature was optionnal and i have never heard of anyone using it. I have never touched it so it may be broken since 2.6. svn path=/trunk/; revision=2573

Not all UNIXes provide an easy way to get the filename if you have
|
||||
the device it is mounted on and its inode.
|
||||
|
||||
Well, under Linux we can simply read /proc/<pid>/maps to get the filenames
|
||||
but I don't see any way to get this under FreeBSD.
|
||||
|
||||
In this case you can give configure the optional `--with-libgtop-inodedb'
|
||||
parameter to build this stuff here.
|
||||
|
||||
It uses the GNU database library `gdbm' to find the inode in a database
|
||||
which is created when libgtop is installed. This should be reasonable
|
||||
fast since the entire filesystem only needs to be traversed once when
|
||||
libgtop is installed (and each time you install new software, of cause).
|
||||
|
||||
We have two databases:
|
||||
|
||||
* First the system administrator may place a system-wide database
|
||||
in `$(prefix)/var/libgtop/inodedb.db' when installing libgtop.
|
||||
|
||||
* Every user can have his/her own one in `~/var/libgtop/inodedb.db'.
|
||||
This one has precedence over the system wide one.
|
||||
|
||||
The `mkinodedb' program which is build in this directory takes two
|
||||
command line arguments: the full pathname of the database to be created
|
||||
and the name of a configuration file consisting of directory and file names
|
||||
each on a line by itself - see `/etc/ld.so.conf' for an example.
|
||||
|
||||
Putting a directory name in this file means all regular files found in this
|
||||
directory are included in the database, but it will not recursively descend
|
||||
into subdirectories (for instance, we want everythink in `/usr/lib' but not
|
||||
every single file in `/usr/lib/sgml'). You can also use filenames to include
|
||||
a single file.
|
||||
|
||||
To use this interface in your program, you first have to call
|
||||
`glibtop_inodedb_open ()':
|
||||
|
||||
glibtop_inodedb *
|
||||
glibtop_inodedb_open (unsigned databases, unsigned long cachesize)
|
||||
|
||||
glibtop_inodedb *
|
||||
glibtop_inodedb_open_s (glibtop *server, unsigned databases,
|
||||
unsigned long cachesize)
|
||||
|
||||
There are some constants defined in <glibtop/inodedb.h> for the `databases'
|
||||
parameter - you can use zero as default:
|
||||
|
||||
#define GLIBTOP_INODEDB_SYSTEM 1
|
||||
#define GLIBTOP_INODEDB_USER 2
|
||||
#define GLIBTOP_INODEDB_CACHE 4
|
||||
|
||||
The `cachesize' gives the size of a not yet implemented in-memory cache for
|
||||
looked up entries.
|
||||
|
||||
This function will return a pointer of type `glibtop_inodedb *' which you need
|
||||
to lookup an entry in the database.
|
||||
|
||||
To look up an entry, use the `glibtop_inodedb_lookup ()' function:
|
||||
|
||||
const char *
|
||||
glibtop_inodedb_lookup (glibtop_inodedb *inodedb,
|
||||
guint64 device, guint64 inode)
|
||||
const char *
|
||||
glibtop_inodedb_lookup_s (glibtop *server, glibtop_inodedb *inodedb,
|
||||
guint64 device, guint64 inode)
|
||||
|
||||
It will either return a pointer to the filename - which you have to
|
||||
`g_free ()' once done with it - or NULL on error.
|
||||
|
||||
You can use the `file_by_inode' program in this directory to test the
|
||||
interface - just call it with two command line arguments: the device number
|
||||
and the inode number.
