glusterfs.git/libglusterfs, branch v3.3.1qa1

core: check for pre-allocated blocks in backend fs, fix it.

2012-08-17T06:58:13+00:00

There is a possibility that the backend FS (like XFS) can
allocate blocks beyond EOF for better performance reasons, which
results in 'st_blocks' with higher values than what is consumed by
the file descriptor. This would break few logic inside GlusterFS,
like quota behavior etc, thus we need the exact number of blocks
which are consumed by the file to the higher layers inside GlusterFS.

Currently, this logic won't work for sparse files (ie, file with holes)

cluster/dht: Optimize readdirp calls in DHT

2012-08-17T05:25:17+00:00

Bring in option which is supported by posix xlator
to filter out directory's entries from being returned.
DHT would now request non-first subvols to filter out
directory entries.

dht xlator-option readdir-optimize will enable this
optimization

acl: enable handling of FMODE_EXEC flag

2012-08-09T16:38:37+00:00

on linux systems, with open(), we can get below flag as per
'linux/fs.h'.

/* File is opened for execution with sys_execve / sys_uselib */
'#define FMODE_EXEC              ((fmode_t)0x20)'

Instead of adding '#include , its better to copy this
absolute number into other variable because then we have to deal
with declaring fmode_t etc etc..

With the fix, we can handle the file with '0711' permissions in
the same way as backend linux filesystems.

calls to dict_allocate_and_serialize() are not 64-bit clean

2012-08-03T10:54:50+00:00

All calls to dict_allocate_and_serialize() pass the address of a 32-bit
type, but must cast it to the 64-bit pointer type (size_t *).

This happens to work on LE machines, but even if it's apparently benign,
it's still a bug. On BE machines it is not benign.

GF_PROTOCOL_DICT_SERIALIZE() hacks around it by creating a size_t temp
var, but that's, well, a hack, IMO when you consider that all the callers
are actually passing &; the param should just be a u_int * and
eliminate the buggy casts and the temp var in the macro.

Nobody apparently uses the Fedora/EPEL PPC RPMs, but they might. People
are trying to build gluster.org bits on SPARC and tripping over this.
