TODO list (in order of priority)
---------
- integrate statfs patch
- find alteratives way to determine PGDATA at runtime (by NOT
asking the Postgresql server)
- find a way to calculate PGDATA while compiling
- handling of most file system metadata
- ownership: how is this done depending on
per-user or root mounts? think about security
here!
- extended attributes
- how much access control is possible if not using default_permissions:
- group membership doesn't work (design limitation in FUSE)
- Selinux will not work because we can't assign parallel contexts,
maybe forcing a security context mount option is an option, but
so far the fuse mount helper doesn't pass the Selinux mount option
to the kernel
- fill in st_nlink correctly
- strategy for half-blocks, help PostgreSQL optimize disk usage
of data in BYTEA columns. Try to support tails of growing files
and tiny files (without padding to the block size)
- establish self-containment (with respect to
a temporarily unavailable Postgresql server)
- minimal SELinux support, i.e. one fix security context
per mount point
unique: 8, opcode: GETXATTR (22), nodeid: 7, insize: 68
unique: 8, error: -38 (Function not implemented), outsize: 16
lsetxattr("file.sgml", "security.selinux", "system_u:object_r:httpd_sys_content_t:s0", 41, 0) = -1 EOPNOTSUPP (Operation not supported)
- investigate SELinux races
- make some performance tests, see http://archive09.linux.com/feature/127055
- add options to specify:
- prefix for tables and indexes
- a --init and a --clean option, using schema.sql as template?
- support options to specify names of tables, prefixes or/and namespaces?
- optimizations:
- use prepared statements, measure performance gain
- use of asynchonous read/writes
- optimize using .flag_nullpath_ok = 1, check functions if they can live without
path (but for verbosity and error messages), maybe add path to PgFuseFile
- make table names options, in order to store many pgfuse filesystems in one
database
