TODO revision 1.1
1 $NetBSD: TODO,v 1.1 2007/05/19 12:03:30 pooka Exp $ 2 3 Document some possible user-visible changes that may take place. 4 For a complete list, please dump my brain and excavate. 5 6 * figure out what do to with struct vattr, maybe introduce some 7 vattr-like puffs-specific structure (translation costs?) instead 8 of direct exposure 9 10 * get rid of pid argument on most ops - virtually nobody (not the nfs guy) 11 uses it and we should provide the lwp also. introduce puffs_caller(pcc)? 12 13 * make puffs_node opaque outside the library 14 15 * make it possible to cache symlink names and getattr results in 16 the kernel ... although I'm not as critically concerned with the 17 kernel caching as I am with userlevel caching 18 19 * try to implement a kernel policy for VOP_ACCESS, it's called 20 very very often - but this requires some kernel caching 21 22 + also try to figure out how to implement it in cases where it's 23 more difficult to do, e.g. how can we know readdir on sshfs will 24 fail without actually trying to read the directory? If we fail 25 readdir itself, it's treated as success 26 27 * implement file system layering .. this will most likely bring 28 massive changes to how the ops vector is handled, for instance. 29 pcc/pu division should stay quite like the way it is now, but 30 maybe there will be layer specific ops. 31 32 * make puffs more like kernel vfs - or make kernel vfs more like puffs 33 34 * decide what to do about setback operations. they kind of violate 35 the transparency of FAF for op handling. also decide if the refs 36 parameter in inactive is still needed 37 38 * fix incoming requests to not require memcpy with continuations 39 (not user-visible?) 40 41 * make continuations play with libpthread, lib/36011 (not user-visible?) 42 43 * clean up the request dispatching / continuation code (not user-visible?) 44
