When mount option use-readdirp=yes is provided it starts using
fuse-kernel's readdirp.

fuse-bridge: Pass unknown option down to fuse

2012-09-12T21:39:06+00:00

In Linux, certain "filesystem-specific" options (passed in string form in last
argument to mount(2)), such as "rootcontext" or "context" are in fact common to
all filesystems, including fuse. We should pass them down to the actual
mount(2) call untouched.

This is achieved by adding "fuse-mountopts" option to mount/fuse translator and
adjusting the mount helper to propagate it with unrecognized options as they
are encountered.

mount/fuse: add mount-option "enable-ino32" for the native client

2012-09-07T01:32:26+00:00

By default the GlusterFS-native client uses 64-bit inodes. Some 32-bit
applications can not handle these correctly. Introduce a client-side
mount option "enable-ino32" which causes the FUSE-client to squash the
64-bit inodes into a 32-bit value.

fuse-bridge: expose negative entry caching of FUSE

2012-07-19T16:05:30+00:00

Fuse kernel module supports caching negative entries, enabled
by specifying a timeout while returning ENOENT to lookup. This
patch enables the functionality to be enabled with the command
line.

Also fixed a typo bug in mount.glusterfs.in.

libglusterfs,mount/fuse: implement gidcache mechanism in fuse-bridge

2012-07-17T15:11:48+00:00

This change genericizes the cache mechanism implemented in commit
8efd2845 into libglusterfs/src/gidcache.[ch] and adds fuse-bridge as
a client. The cache mechanism is fundamentally equivalent, with some
minor changes:

  - Change cache key from uid_t to uint64_t.
  - Modify the cache add logic to locate and use an entry with a
    matching ID, should it already exist. This addresses a bug in
    the existing mechanism where an expired entry supercedes a newly
    added entry in lookup, causing repeated adds and flushing of a
    cache bucket.

The fuse group cache is disabled by default. It can be enabled via
the 'gid-timeout' fuse-bridge translator option and accompanying
mount option (i.e., '-o gid-timeout=1' for a 1s entry timeout).

fuse/md-cache: add support for the 'fopen-keep-cache' mount option

2012-07-13T16:46:09+00:00

fopen-keep-cache disables unconditional page-cache invalidations
on file open in fuse (via FOPEN_KEEP_CACHE) and replaces that
behavior with detection of remote changes and explicit
invalidations from mount/fuse. This option improves local caching
through the page cache and native client.

This change defines a new 'invalidate' translator callback to
identify when an inode's cache mapping has been determined to be
invalid. md-cache implements the policy to detect and invoke
inode invalidations. fuse-bridge and io-cache implement
invalidate handlers to invalidate the respective caches (page
cache in the case of fuse).
