Release 0.36
Redhat kernel + syscall
Release 0.37:
Darwin 10.2
ubc
find fd/vnode leak (fhopen)
OSF/1 5.1a
ubc
FreeBSD 4.5
ubc ?
OpenBSD 3.1 and NetBSD 1.5
dubble-buffer (X ?)
Linux 2.4
ubc
(sparc64)syscall table 64 vs 32 bits syscalls
Solaris 9
ubc
TODO-list, in no particular order.
Please mail arla-drinkers@stacken.kth.se if you want to work on
any of these things so we don't do double work.
Store fcache entries on a list on the appropriate volcache entry to
make volume callbacks faster.
split cred for !bsd to rd_cred and wr_cred
fix weirdness with fake mount points
installattr (token w/o data) (ls -l ; ls foo ; ls bar)
write2: bsd
fix usage of token between nnpfs and arla
fix usage of open-token between nnpfs and arla
fs flushall:
-volume ?
is this really good ?
nnpfs/linux:
check that we DTRT wrt Documentation/filesystem/Locking.txt
nnpfs/*: teach nnpfs to read AFS directories for readdir
merge in tol's code from winnt
nnpfs/linux: check if we can hook into vm_operations/address_space to
figure out when cache pages are dirty and need to flushed.
dubble buffer instead, look how its done on netbsd nnpfs
*/Makefile.in: allow creation of shared libraries
*/Makefile.in: homogenize
arlad/nnpfs: implement advisory locking
arlad: more improvements on writing in disconnected mode
arlad: fallback to disconnected mode if networking is not working (possibly per cell)
arlad: more consistency checks before recovering state
arlad: remove unused stuff from FCacheEntry
nnpfs/aix: figure out where the PAG should be stored
nnpfs/irix: fix syscall and implement setgroups wrapper
nnpfs/irix: port to Irix 6.5
nnpfs/solaris: verify multithreadness, merge xnode and vnode mutex locks
nnpfs/sunos: implement setgroups wrapper
OPTIMIZATIONS
This is a list of posible optimizations that could be done to different parts
of arla.
- Delay reads and writes to cache and AFS-servers. Make the more operations
in one batch. (possible with rx?) Especially directories don't have to be
synced for every operation.
- send more messages to/from arlad in one sweep. (lookup on whole path in one
message, getattr+getdata, etc..)
MILKO
Filbunke, the nnp-class-server generation:
- callbacks
- logging
- fsck/salvage, stability, more tests
- SPEED, real i*op
- volser (?)
- pts,vldb
- security
